- FIG 6 Oct. 26, 1954 E. RAPHAEL 2,692,382
- the invention relates to machines for inserting pins or similar fastening devices in cloth fabrics and the like and, more particularly, is concerned with a machine whereby curtain or drapery pins or pin-hooks may be applied or inserted more or less automatically to or in a curtain, drapery or the like in a uniformly desirable manner and at a desired place. While the machine herein disclosed, or certain of its features, may be employed for other purposes, it is especially useful for the particular purpose of applying pin-hooks, i. e. combination pins and hooks by which curtains and drapes are hung, to curtains and drapes. Therefore, in the interest of simplification of description, the machine will be revealed in the form peculiarly adapted to that particular purpose.
- Draperies, curtains and other hangings for interior decoration or for purely utilitarian purposes are hung or supported in various ways but commonly are hung upon rods, taut cables or the like.
- the drapery or other hanging may be mounted directly upon the supporting rod or other device as Where a rodpocket is provided in the hanging along a marginal portion thereof for reception of the rod support.
- the hangings are equipped with pin-hooks which include a pin shank portion to be inserted in or pinned to the material and a hook portion to be hooked over the supporting rod or hooked into eyelet or other devices in turn carried by the rod or support.
- pinhooks Much depends on correct placement of the pinhooks for attainment of desired effects and cor rect appearance of the hanging. If the pinhooks are of such type or construction that proper placement requires the pin shanks to be so placed in. the material for instance, to lie in parallel array, or to be arranged at equal intervals transversely of the hanging, or to be located at the same or some predetermined distance from the upper transverse marginal edge of the material or from a heading line, then any departure from such placement, array or location may cause the in-hooks, supports or drapes or all to function improperly and, in any event, will be almost certain to destroy or prevent the desired effect or appearance. Therefore, it is of utmost importance that the pin-hooks be correctly pinned or set in the drapery or curtain and in the manufacture of such.
- One of the principal objects of this invention is to provide a machine by which pin-hooks. or other pin devices may be placed speedily and with absolute precision in drapes, curtains and the like.
- Another important object is to provide a machine of the character mentioned whereby drapes or the like and other fabric items, Whether plaited, ruflled, folded or plain piece goods, may be pinned with pin-hooks or other pins or similar fastening devices for hanging or other purposes.
- Still another important object is to provide a machine, of the type and for the purposes specicapable of placing a pin-hook or a pin of other type in a pre-formed plait, seam or other part of a fabric item and at a predetermined place and in predetermined orientation therein with respect to the plait, seam or part and/or some other physical feature such as an edge of a heading or hem margin of the item, and, in connection therewith or independently thereof, to provide means for accommodating various thicknesses of materials and plaits, seams or folds.
- a further object of a primary nature is to provide an arrangement of mechanism whereby a pin-hook or other pin may be so engaged with the fabric or other material that the final relative attitude of the pin shank and the plane or line of the material along the pin shank will be more or less parallel or, so that the material, between places engaged by the pin shank, may be straight and smooth, thereby to avoid puckering or launching of the material along the pinned portion where puckering or bunching is undesirable.
- the machine embodies a Work support and a pin inserting mechanism so constructed and related that a pin, point first, and the pin shank are caused to travel in a path, relative to that portion or part of the material in which the pin is to be secured, such as will intercept and enter the material at the desired point or place of entry, the pin point and shank being thereupon and thereafter caused to travel in a path whereby the pin point will lie or be disposed at a desired place or position wholly within a plait, seam or fold, or will reenter or emerge from the material layer or layers at a desired point or place after the usual manner of a pinning operation heretofore performed by hand.
- Still further objects include the provision of a work support of special utility and functions, a novel mechanism for guiding and inserting pin-hooks, a mechanism for securing material in a predetermined position while the pin-hooks are inserted, and magazine feed means for holding a plurality of booked or loose pin-hooks and supplying them successively as needed to the guiding and inserting or applying mechanism.

- the other end of the crank arm iii i is secured to the shaft 12 for oscillation of that shaft.
- the side of the frame adjacent to the crank arm I it and rocker arm 3? has a vertically extending slot Hi1 of a length sufficient to permit the shaft 12 to move up and down to an extent corresponding to vertical movement of the .pinsetter head in the guideways 62.
- Pin-hooks could be fed to the setter head and the setting arm 65 by hand but it is preferable that they be fed automatically from a magazine holding a substantial number for successive advancement to the setting mechanism.
- the machine illustrated is provided with a magazine feed mechanism adapted to hold a substantial number of pin-hooks and from which the pin-hooks may be fed automatically as .required, one at a time and in proper oriented position, to the inserting mechanism.
- the magazine is of such type as will permit a plurality of pin-hooks to be assembled together in the same order or register in booked relationship as with lacquer, or the like, for insertion on an arbor in the magazine in such multiple unit form, yet also of such type as will permit the pin-hooks to be loaded individually without booking.
- the magazine and pin-hook feed and the inserting mechanism desirably are of such construction and arrangement that the magazine may be removed with ease for reloading and replacement or for inner-change with a different magazine carrying a full charge of pinhooks.
- pin-hooks of different sizes or different form might be utilized.
- the housing member 6'! has an opening I88 conforming generally to the overall profile outline of a pin-hook such as that shown in S-A as that pin-hook may be viewed when in the position and with the orientation illustrated in Fig. 5-A.
- the opening 588 extends from the exterior of the housing member 6? to the guide slot provided by the recesses 58 thereby to permit the pin-hooks to pass from th magazine into the guide slot and on to the end of the pinsetter arm as shown in Fig. 5-A.

- a lower pin-hook guide member I I4 Disposed in the bottom of channel member 109 and relatively permanently secured therein as by screws 5 i3, is a lower pin-hook guide member I I4 which is formed with a groove H5 extending throughout its length, the groove being transversely contoured as indicated in th section of Fig. 8 thereby to conform generally to the lower part of the outline of a pin-hook when oriented as above stated.
- Fitting on top of and mating with the lower guide lid within the channel I09 is an upper pin-hook guide member I it formed with a groove HT conforming in transverse contour to the upper part of the outline of a pinhook
- the upper guide H5 also has a longitudinally extending groove H8 adapted snugly but removably to receive a pin-hook arbor H3 which fits therein throughout its length, and is secured therein by screws H9, and has a projecting tongue portion l 2! which is received in the opening N38 for centering and aligning purposes.
- Pinhooks in multiple number, whether booked or separate, are slidably threaded on to the arbor and are fed forward therealong into the opening I08 and on to the end of the setter-arm 69 by a follower I22 carried on a guide rod I 23 and slidable therealong within the confines of the upper and lower pin-hook guide members H4, N6, the follower having a configuration permitting it freely to slide longitudinally in the grooves of the upper and lower guide members and about the pin arbor H9.
- a spring I24 surrounds the rod I23 and reacts between a fixed abutment I25 on the outer end of the rod and the follower I22, normally urging the follower toward a limiting abutment or stop I26 at the inner end of the rod.
- the lower end portion I 2i ⁇ of the arbor I I9 is forked to straddle the rod I23 and spring I26.
- the outer end of the rod I23 has a return bent portion I26 the free end of which is provided with a hook part I21 adapted to pass into a drilled bore I28 extending through the U-shaped housing member I09 into the lower pin-hook guide member H t.
- a pair of handles I29 secured to the upper pin-hook guide H6 may be employed for the removal of the upper pin-hook guide member HE and the pin-hook arbor III) after the rod I23, spring I24 and follower I 22 have been removed as an assembly, the rod end I21 being first removed from the bore I28.
- a pin I3I] (Fig.
- the drape is composed of cloth fabric, as shown more particularly in Figs. 10 to 13, inclusive, and has a cloth fabric lining on the reverse side, that it is to have a heading I3I extending to a predetermined height above the line of support, that pinch or multi-fold plaits extend across the heading in transversely spaced relation to one another, that pin-hooks are to be placed or inserted in the fabric material on the reverse side thereof at each fold or plait and at exactly the same distance from th top margin or top edge of the heading, that the pin shanks or hooks or both are to be arrayed in parallelism and perpendicular to the top margin of the heading, and that the pin points as well as the shanks are to be concealed within the material or the drape folds so that neither of such pin-hook parts will grin through at either side of the drape.
- drapery plaits of the type illustrated herein may consist of several pinch folds of which three, I32, I33, I34, are shown in Fig. 6 and in Figs. 10, 11 and 13, wherein the cloth material is shown as doubled back upon itself to provide four folds I35, I35, I31 and I33, and secured in such folded condition.
- the heading I3I may be tacked down by sewing I39.
- the usual and ordinary method of securing the folds of the illustrated plait is by sewing th two outermost folds I35 and I38 directly together by sewing down the valleys of the folds, as shown at I45], over their length or height across the heading I3 I and thereafter tack sewing the three pinch folds I32, I33 and I34 at the bottom of the heading, as indicated at I 4 I the tacking being done at the lower ends of the folds or plaits and usually within the id drapery heading area or close thereto.
- These plait forms and sewing thereof are old and well known practices as shown and described, for instance on pages 119, of The New Encyclopedia of Modern Sewing, Wm. H. Wise 8; Co., Inc., N.
- the first preliminary operation may be the forward or rearward adjustment of the work support and work supporting shoes II, II to set the work margin abutment flanges 55 at such predetermined distance from some fixed or datum point circumferentially about the axis of shaft H, as will result in placement of some particular point on or part of a pinhook at that distance from the top marginal edge of the drape heading as will give the drape its support at the desired line.
- the scale markings and index plate E'I may be graduated and arranged to determin the desired position of the work stops 55. Upon release of the clamp knob 22 the adjustment knob 35 may be rotated in one direction or the other to turn the shaft I?
- the next step may be the adjustment of the slot width between shoes ll, 4!. If the drapery plaits are all of the same general type and transverse thickness, only one transverse setting of the shoes may be required to provide the correct slot Width for disposition of all of such plaits therein so that it is not necessary to readjust the slot width until a thicker or thinner plait is to be pinned. Adjustment of the slot width is readily accomplished by rotation of the knurled knob It which, through the oppositely threaded portions of shaft t6, simultaneously moves both work support shoes 4!, 4
- the slot width preferably is such as to furnish a firm but light pressure on the material at opposite sides of the plait but the lips of the projections 52, 52' should not be so close together as to interfere with the insertion or placement of the pin point and shank of a pinhook.
- the upper edge is thrust over the surfaces of the work support shoes il, ill with the plait to be pinned depending into the slot and with the material at each side of the plait disposed downwardly and outwardly over the inclined upper surfaces 53, 53' and the cylindrical surfaces 5i, iii of the work shoes after the manner illustrated in Fig. 6.
- the upper edge of the drape is brought up evenly against the adjacent faces of the work stops 55.
- the slot 183 permits freedom of movement of the crank arm within limits with respect to the rocker arm since the rocker and crank arms have difierent swinging radii and other differential movements.
- the fabric is clamped to the work support. but there has been little if any rotative movement of the shaft l2, lever arm H and pin-setter arm 69 as Fig. 5-A indicates. However, at this time a pin-hook will have entered the slot and been disposed as shown over the reduced end of setter arm.
- the pin portion of this pin-hook normally is closed against the hook portion as shown in Figs. 5-A and 8-A.
- the hook portion H is a loop somewhat of horse-shoe shape since the loop ends are curved in toward one another while the shank part S of the pin portion is bent back rather sharply at one side of the hook loop so that it is substantially tangent to the outer side of the loop of the hook portion, as indicated at C.
- shank portion actually makes contact with the loop of the hook portion or merely extends in close proximity thereto generally is not of material consequence so long as the gap between these portions at C is sufficiently narrow and the pinhook wire has a degree of resilience or spring quality suificient to offer resistance to the escape of the fabric from within the small loop betvveefi such portions.
- the shank portion terminates in the usual point P.
- the opposite or free end of the hook portion H terminates in an outwardly flared nib F which is designed primarily to facilitate engagement of the hook over drapery supports such as rods and by reason of this flared part the pin-hook has greater transverse width at this place than the transverse width at any other section.
- housing members $1, -61 terminate in a plane parallel to a tangent or substantially parallel to a tangent to the upper edge of the arcuate lips of the work support projections 52, 5.2 substantially at the mean of the pin shank length so that, when the setter head is in its down position, as shown, the terminal surface 86 becomes substantially tangent to. the arcuate edges of the work support lips and the pin-hook guide slot is opened on its outer side for emergence of the pin shank portion S including point P.
- the spring ID! Upon release of the treadle 99, the spring ID! will return all of the operating parts of the machine to their initial inoperative positions the inserted, pin-hook, of course, remaining where placed in the material.
- the magazine mechanism operates to place the next pin-hook over the receiving end of the setter arm which, until such position is attained serves to obstruct the entry of pin-hooks into the guide slot.
- the fabric clamp With the return of the setter head to its uppermost or inoperative position, as in Fig. 3, the fabric clamp is raised away from the material to. permit the drape or other work to be removed.
- a machine for setting pin-hooks comprising, means for supporting fabric having a pre-formed fi-xed plait with the plait in a predetermined po- 13 sition, and means for inserting a pin-hook in the fabric at the plait with the pin shank of the pinhook extending substantially longitudinally with respect to the plait of the fabric and the hook in predetermined relation to the shank.

Patented Oct. 26, 1954 PINHOOK SETTING MACHINE FOR DRAPERIES AND THE LIKE Edwin Raphael, Holland, Mich, assignor to Edwin Raphael Company, Inc, Holland, Mich, a corporation of Illinois Application August 20, 1952, Serial No. 305,415
26 Claims.
The invention relates to machines for inserting pins or similar fastening devices in cloth fabrics and the like and, more particularly, is concerned with a machine whereby curtain or drapery pins or pin-hooks may be applied or inserted more or less automatically to or in a curtain, drapery or the like in a uniformly desirable manner and at a desired place. While the machine herein disclosed, or certain of its features, may be employed for other purposes, it is especially useful for the particular purpose of applying pin-hooks, i. e. combination pins and hooks by which curtains and drapes are hung, to curtains and drapes. Therefore, in the interest of simplification of description, the machine will be revealed in the form peculiarly adapted to that particular purpose.
Draperies, curtains and other hangings for interior decoration or for purely utilitarian purposes are hung or supported in various ways but commonly are hung upon rods, taut cables or the like. In some instances the drapery or other hanging may be mounted directly upon the supporting rod or other device as Where a rodpocket is provided in the hanging along a marginal portion thereof for reception of the rod support. More often, however, and especially for hangings of drapery and draw-curtains, the hangings are equipped with pin-hooks which include a pin shank portion to be inserted in or pinned to the material and a hook portion to be hooked over the supporting rod or hooked into eyelet or other devices in turn carried by the rod or support.
Much depends on correct placement of the pinhooks for attainment of desired effects and cor rect appearance of the hanging. If the pinhooks are of such type or construction that proper placement requires the pin shanks to be so placed in. the material for instance, to lie in parallel array, or to be arranged at equal intervals transversely of the hanging, or to be located at the same or some predetermined distance from the upper transverse marginal edge of the material or from a heading line, then any departure from such placement, array or location may cause the in-hooks, supports or drapes or all to function improperly and, in any event, will be almost certain to destroy or prevent the desired effect or appearance. Therefore, it is of utmost importance that the pin-hooks be correctly pinned or set in the drapery or curtain and in the manufacture of such. furnishings great care must be and is exercised with that end in view. Since the operation of inserting Iii or placing the pin-hooks has been performed manually hereto-fore and since so much care is required in performing that operation for reasons stated, a substantial part of the labor and expense involved in the manufacture of items such as curtains and drapes may be attributed to this phase of the manufacture.
One of the principal objects of this invention is to provide a machine by which pin-hooks. or other pin devices may be placed speedily and with absolute precision in drapes, curtains and the like.
Another important object is to provide a machine of the character mentioned whereby drapes or the like and other fabric items, Whether plaited, ruflled, folded or plain piece goods, may be pinned with pin-hooks or other pins or similar fastening devices for hanging or other purposes.
Still another important object is to provide a machine, of the type and for the purposes specicapable of placing a pin-hook or a pin of other type in a pre-formed plait, seam or other part of a fabric item and at a predetermined place and in predetermined orientation therein with respect to the plait, seam or part and/or some other physical feature such as an edge of a heading or hem margin of the item, and, in connection therewith or independently thereof, to provide means for accommodating various thicknesses of materials and plaits, seams or folds.
A further object of a primary nature is to provide an arrangement of mechanism whereby a pin-hook or other pin may be so engaged with the fabric or other material that the final relative attitude of the pin shank and the plane or line of the material along the pin shank will be more or less parallel or, so that the material, between places engaged by the pin shank, may be straight and smooth, thereby to avoid puckering or launching of the material along the pinned portion where puckering or bunching is undesirable. In this connection it should be mentioned that the machine embodies a Work support and a pin inserting mechanism so constructed and related that a pin, point first, and the pin shank are caused to travel in a path, relative to that portion or part of the material in which the pin is to be secured, such as will intercept and enter the material at the desired point or place of entry, the pin point and shank being thereupon and thereafter caused to travel in a path whereby the pin point will lie or be disposed at a desired place or position wholly within a plait, seam or fold, or will reenter or emerge from the material layer or layers at a desired point or place after the usual manner of a pinning operation heretofore performed by hand.
Still further objects include the provision of a work support of special utility and functions, a novel mechanism for guiding and inserting pin-hooks, a mechanism for securing material in a predetermined position while the pin-hooks are inserted, and magazine feed means for holding a plurality of booked or loose pin-hooks and supplying them successively as needed to the guiding and inserting or applying mechanism.
Many other objects as well as the advantages and uses of the invention will be appreciated and understood after reading the following description and claims and upon viewing the accompanying drawings in which:

Fig. 13 is a sectional view taken along the section line I 3-l3 of Fig. 12.
The drawings generally portray a machine built and successfully operated for application of pinhooks to draperies and the like. In the construction of that machine it was deemed desirable to employ several different kinds of material (metal) for different parts and to an extent the section lining of the drawings hereof will reflect the kind or type of material employed in making that machine. Therefore, the section lining in the drawings, where departing from the usual simple type used to designate metal section, follows standards prescribed for different metals by American Standard Symbols for Section Lining as represented in a number of reference Works including Machinerys Hand Book, by Oberg and Jones, 14th ed. Copyright 1949, The Industrial Press, New York. Of course, choice of construction materials for the various parts of a machine of a character of the instant one is largely a matter for the discretion of the machine designer.
Construction The machine frame includes a base portion l2 adapted to be mounted upon a bench l3 fragmentarily illustrated in Fig. 2 and to be held thereon by suitable bolts passing through drilled openings 14 extending through bosses l5 cast integral with the base and other parts of the frame. Rising from the sides of the base l2 and integral therewith are a pair of spaced flanges It which are drilled on aligned axes for the passage of a shaft H upon which a work support base or work-shoe holder 18 is secured as by a pin l 9, the work support base I8 being drilled for passage of the shaft l1 therethrough. One end of the shaft ll, the left hand end viewing Fig. 1, is threaded as indicated at 21 for reception of a knurled clamp knob 22 which has a sleeve portion 23 the end of which is adapted to make frictional contact with the side of the adjacent flange I t to lock the shaft l1 against rotation of oscillation relative to the machine frame.
At its opposite end, the shaft ll projects outwardly beyond the adjacent flange I6 for reception of an elongated hub 24 of a worm gear 26 fixed on and to the shaft by a pin 25, the hub 24 being disposed so that one radial face normally bears against the exterior side of the adjacent flange [6. The worm gear 26 is housed within a gear case composed partly by an outwardly projecting circular part of a flange 21 integral with the adjacent flange iii of the machine frame and. a cover plate 28 secured to the first part by cap screws 29. The lower portions of the flange 2'! provide spaced vertical walls which are drilled on aligned axes for reception of a shaft 3! r0- tatably mounted therein and carrying a worm 32 in meshing engagement with the worm gear 26. The worm 32 is secured to the shaft 3| for rotation therewith and may have thrust engagement at its opposite ends with the adjacent interior walls of the depending parts of flange 27. A thrust collar 33 fixed on the rear end of the shaft 3! by a pin 34 permits the shaft 3! and worm 32 to rotate while retaining the shaft against displacement in one direction. A knurled knob 35 is secured to the shaft 3| for rotation of the shaft and may abut against the adjacent exterior side of the adjacent flange 21 to prevent rearward displacement of the shaft. When the knurled clamp knob 22 is unscrewed to release its inner end from frictional engagement with the side of the adjacent flange l6, rotation of the knob 35 will rotate the worm 32 whereby to rotate the worm gear 26 and the shaft ll. Since the shaft l l is keyed to the work support I 8, the latter will be swung forward or backward as the case may be, relative to and between the machine frame flanges H5.
The work support It rises above the upper ends of the base flanges it and at each side of a center portion is extended laterally and forwardly and rearwardly thereabove as indicated at 36 in Figs. 1, 2, 3 and 6. Extending laterally of the top surface of each of the upper portions 36 is a guideway, the bottom wall of which is designated 3'! and the side walls of which are designated 38, while intermediate of the portions 36 is an upwardly extending projection 39. Each of a pair of complementary work support shoes 51-46, each the mirror image of the other, has an inverted T-shaped guide portion. 42 adapted to seat and to slide transversely of the machine within the guideways 3l38 while gibs 43, which may be secured to the portion 35 by screws, serve to override the fore and rear edges of the guides 42 to prevent displacement of the work support shoes from the guideways.
Each work support shoe is drilled to provide a bore extending through it from side to side on aligned axes transverse to the machine and parallel to the guideways 3138 and guides 42. Each drilled bore is tapped at its outer side as indicated at M for threaded mating engagement with threaded portions d5 of a shaft 46, one of the threaded portions d5 bearing a left hand thread and the other a right hand thread for a purpose to be described. The inner portions of the drilled bores may be counter-bored as indicated at ll to provide clearance for the shaft 86 which also passes through and has bearing in a drilled bore in the projection 39. At each side of projection 39 shaft to is equipped with a thrust collar 48 for rotation therewith in abutting engagement with the opposite sides of projection 39. On one end of the shaft to, a knurled knob 49 is secured so that the shaft may be rotated in either direction and since the threads of portions are engaged with the correspondingly threaded portions M of the work support shoes ib-4!, these shoes will either be moved toward or from one another transversely of the machine.
The upper surface 52 of each work support shoe LL-t l could be flat or of other contour but preferably is arcuately curved from front to rear, desirably being generated as a portion of a surface of a cylinder the axis of which is coincident with the axis of the shaft ii. The inner or adjacent edges of the work support shoes 3!l|' project toward one another as indicated at 5252', overhanging the center part of the shoe holder base member 58, and their upper surfaces 53-53 incline upwardly to their parallel terminal and adjacent margins from the surfaces 5l-5l. The inclined surfaces 5353' are arcuate in a fore and rear direction concentric with the axis of the shaft I! and surfaces 5l-5l. The adjacent marginal edges of projecting portions 52-52 are rounded and their under sides may be tapered away from one another as indicated at 54-54 for a purpose which will later appear. The rear end or margin of each of the surfaces 5 l5 l terminates in a radially extending flange 55-55, the two flanges being aligned with one another and together serving as an abutment against which a fabric edge or margin may be abutted for gauging purposes. The upper portion of each of the frame flanges It, the outer upper surface of flange 2'! and the upper edge of cover plate 28 may be rounded as indicated at 56 to permit the work support shoes and base to swing freely forward and backward about the axis of shaft l1 and the forward upper portion of one of the flanges It may be provided with index markings 56 while the support base l8 may be provided with a fixed gauge marker 5'! for registration with the index markings 56 thereby to determine the rotated position of abutment flanges 55-55 with respect to a vertical plane containing the axis of shaft I? or with respect to the position at which the pin-hooks are to be placed.
Integral with the flanges l6 and base portion i2 and extending upwardly from the base portion at the rear thereof are a pair of parallel frame members 53 which at their upper ends extend forward to provide portions 59 overhanging the work support shoes and associated parts in spaced relation thereto. At their forward ends, portions 59 are integrally joined together throughout their vertical height as indicated at 6!. Portion 5| is provided with a vertically extending T-shaped guideway 62 (see Fig. 6-A) formed in part by removable gibs 62 and within this guideway a correspondingly formed slide 63, integral with what will be termed the pin-setter head, generally designated 64, is mounted for vertical reciprocatory movements toward and from the work supporting shoes and work support. The upper end of the guideway 62 may be closed by a plate 65 secured to the frame portion 6| by cap screws 66.
The pin-setter head 64' comprises a pair of semi-circular housing members 6'i6l' each complementary to the other and held together as by screws (55'. Each of the two housing member halves has a semi-circular recess portion 53 mating with the corresponding recess in the other to provide a guide slot for reception of a pin-setter arm $9 carried by a lever arm I! in turn secured to an oscillatable shaft l2 by means such as a pin 73, for swinging movements between p-redetermined limits about the axis of the shaft 12. Each of the housing members til-67 has a pair of portions Hi-l4 projecting toward and substantially abutting against the corresponding projections on the other of these housing members, the innerside of projection M of each housing member being spaced from the adjacent inner side of projection M of such member to provide clearance for limited swinging of the lever arm H and to provide inclined surfaces l5l5' forming limit stops between which the lever arm H may be oscillated. The guide slot over a substantial length of the lower part of the pin-setter head is so dimensioned, transversely, as to receive and, together with the pin-setter arm 69, to guide a pin-hook during the insertion operation.
The pin-setter arm 69 is of arcuate shape to correspond to the curvature of the guide slot provided by the registering recesses 68 between the housing parts 6'|6'I of the pin-setter head 6% and is dimensioned to have a sliding fit within the slot. At its free end arm 89 is cut away or reduced along its top and bottom edges IE-l6 to conform generally to the hook portion H of a drapery pin-hook as clearly illustrated in Figs. -A and 5-3. Preferably the dimensions of the reduced end of the pin-hook setter arm iii! are such that it is not thicker, transversely, than the diameter of the wire of which the pin-hook is made and of a thickness between its top and bottom edges -16 somewhat less than the narrowest portion of the hook part H since, during the pin-setting operation, the hook part H is to be partly collapsed or sprung together as will be explained hereinafter.
The rear edge of each of the projections is is provided with half of a vertically extending slot which mates with the other half in the other projection for reception of a stem 18 of a fabric clamp, the lower or clamp portion of which is bifurcated as shown at 19 to provide a pair of tooth-ed fabric clamping feet 31 disposed on opposite sides of the lower end portion of the housing members til-6?, the housing members at their lower ends being cut away as indicated at 2 for this purpose. The fabric clamp has a vertically elongated slot 83 through which the threaded stem of a clamp screw 84 passes for threaded engagement within a threaded bore in one or both of the projections M. By loosening and tightening the clamp screw 84 the fabric clamp may be adjusted vertically to a desired position on the pin-setter head with which it travels toward and from the work supporting shoes.
A boss formed on the side of the upper portion of the right hand frame portion 59 carries a stub shaft 85 upon which a rocker arm 8! is pivotally mounted between the boss 85 and a nut '38 with a washer 89 interposed between the nut and rocker arm. The rocker arm 8'! at its rear end is pivotally connected by a pivot bolt 9! to a link 92 adjustab-ly connected with a connecting rod 93 which, at its lower end, is connected with a second yoke link SE in turn pivotally connected, as at 95, with a foot operated lever 96 pivotally mounted on a pivot pin 91 between the sides of a bracket 98. The bracket 98 may be secured to the floor or upon any suitable pedestal in convenient location beneath the bench 13. A foot treadle 99 is provided on the other end of the lever and a spring ifll connected between a forward end of the foot lever 96 and the bench l3, as by hook Hi2, normally holds the end of the foot lever in the upper full line position shown in Figs. 1 and 3 and dotted line position shown in Fig. 2. When the foot lever 96 is in its upper or inoperative position, the rocker arm 81 will be in the dotted line position shown in each of Figs. 2 and 3.
In the forward end of rocker arm 81 is an elongated slot I03 the long axis of which is in alignment with the pivot axes of the rocker arm on the stub shaft 86 and pivot bolt ti. Projecting from one end of a crank arm I04 is a pivot stud I95 which carries a roller sleeve Hi6 adapted to ride within and between the ends of the slot N33. The other end of the crank arm iii i is secured to the shaft 12 for oscillation of that shaft. The side of the frame adjacent to the crank arm I it and rocker arm 3? has a vertically extending slot Hi1 of a length suficient to permit the shaft 12 to move up and down to an extent corresponding to vertical movement of the .pinsetter head in the guideways 62.
Pin-hooks could be fed to the setter head and the setting arm 65 by hand but it is preferable that they be fed automatically from a magazine holding a substantial number for successive advancement to the setting mechanism. Accordingly, the machine illustrated is provided with a magazine feed mechanism adapted to hold a substantial number of pin-hooks and from which the pin-hooks may be fed automatically as .required, one at a time and in proper oriented position, to the inserting mechanism. Preferably also, the magazine is of such type as will permit a plurality of pin-hooks to be assembled together in the same order or register in booked relationship as with lacquer, or the like, for insertion on an arbor in the magazine in such multiple unit form, yet also of such type as will permit the pin-hooks to be loaded individually without booking. The magazine and pin-hook feed and the inserting mechanism desirably are of such construction and arrangement that the magazine may be removed with ease for reloading and replacement or for inner-change with a different magazine carrying a full charge of pinhooks. Of course, with slight modification of the structure, pin-hooks of different sizes or different form might be utilized.
At a place adjacent to the upper or inoperative position (Fig. 5-A) of the reduced free end of the setter-arm 69, the housing member 6'! has an opening I88 conforming generally to the overall profile outline of a pin-hook such as that shown in S-A as that pin-hook may be viewed when in the position and with the orientation illustrated in Fig. 5-A. The opening 588 extends from the exterior of the housing member 6? to the guide slot provided by the recesses 58 thereby to permit the pin-hooks to pass from th magazine into the guide slot and on to the end of the pinsetter arm as shown in Fig. 5-A. A U-shaped or channel member N39 is provided with lateral flanges [H at one end thereof for abutment against the exterior surface of housing member 5'5 along opposite margins of that housing member defining the opening I 06, cap screws 1 12, passing through those flanges into the housing wall to secure the member I69 in its position where it projects laterally from the side of the machine. Disposed in the bottom of channel member 109 and relatively permanently secured therein as by screws 5 i3, is a lower pin-hook guide member I I4 which is formed with a groove H5 extending throughout its length, the groove being transversely contoured as indicated in th section of Fig. 8 thereby to conform generally to the lower part of the outline of a pin-hook when oriented as above stated. Fitting on top of and mating with the lower guide lid within the channel I09 is an upper pin-hook guide member I it formed with a groove HT conforming in transverse contour to the upper part of the outline of a pinhook oriented in th manner previously stated.
The upper guide H5 also has a longitudinally extending groove H8 adapted snugly but removably to receive a pin-hook arbor H3 which fits therein throughout its length, and is secured therein by screws H9, and has a projecting tongue portion l 2! which is received in the opening N38 for centering and aligning purposes. Pinhooks in multiple number, whether booked or separate, are slidably threaded on to the arbor and are fed forward therealong into the opening I08 and on to the end of the setter-arm 69 by a follower I22 carried on a guide rod I 23 and slidable therealong within the confines of the upper and lower pin-hook guide members H4, N6, the follower having a configuration permitting it freely to slide longitudinally in the grooves of the upper and lower guide members and about the pin arbor H9. A spring I24, surrounds the rod I23 and reacts between a fixed abutment I25 on the outer end of the rod and the follower I22, normally urging the follower toward a limiting abutment or stop I26 at the inner end of the rod. The lower end portion I 2i} of the arbor I I9 is forked to straddle the rod I23 and spring I26. The outer end of the rod I23 has a return bent portion I26 the free end of which is provided with a hook part I21 adapted to pass into a drilled bore I28 extending through the U-shaped housing member I09 into the lower pin-hook guide member H t. A pair of handles I29 secured to the upper pin-hook guide H6 may be employed for the removal of the upper pin-hook guide member HE and the pin-hook arbor III) after the rod I23, spring I24 and follower I 22 have been removed as an assembly, the rod end I21 being first removed from the bore I28. A pin I3I] (Fig. 4) secured to and projecting from the upper pin-hook guide member I I8 rides in a slot I3I provided in the outer end of the channel member 5439 and requires the upper pin hook guide member lit to be removed or slid longitudinally to the left viewing Figs. 1, 4 and 9 for removal of the tongue I2I from the opening I98 before being lifted out of the channel member I69.
Operation In describing the operation it will simplify matters to refer to one manner in which the machine may be employed to apply or insert pin-hooks in interior hangings such as drapes. It will be assumed that the drape is composed of cloth fabric, as shown more particularly in Figs. 10 to 13, inclusive, and has a cloth fabric lining on the reverse side, that it is to have a heading I3I extending to a predetermined height above the line of support, that pinch or multi-fold plaits extend across the heading in transversely spaced relation to one another, that pin-hooks are to be placed or inserted in the fabric material on the reverse side thereof at each fold or plait and at exactly the same distance from th top margin or top edge of the heading, that the pin shanks or hooks or both are to be arrayed in parallelism and perpendicular to the top margin of the heading, and that the pin points as well as the shanks are to be concealed within the material or the drape folds so that neither of such pin-hook parts will grin through at either side of the drape.
As is well known and well established practice in the industry, drapery plaits of the type illustrated herein may consist of several pinch folds of which three, I32, I33, I34, are shown in Fig. 6 and in Figs. 10, 11 and 13, wherein the cloth material is shown as doubled back upon itself to provide four folds I35, I35, I31 and I33, and secured in such folded condition. The heading I3I may be tacked down by sewing I39. The usual and ordinary method of securing the folds of the illustrated plait is by sewing th two outermost folds I35 and I38 directly together by sewing down the valleys of the folds, as shown at I45], over their length or height across the heading I3 I and thereafter tack sewing the three pinch folds I32, I33 and I34 at the bottom of the heading, as indicated at I 4 I the tacking being done at the lower ends of the folds or plaits and usually within the id drapery heading area or close thereto. These plait forms and sewing thereof are old and well known practices as shown and described, for instance on pages 119, of The New Encyclopedia of Modern Sewing, Wm. H. Wise 8; Co., Inc., N. Y., 1946, copyright 1943 by The National Needlecraft Bureau, Inc., revised edition, copyright 1946, Wm. H. Wise 81 Co., Inc. See also page 268 of The Complete Book of Sewing, by Constance Talbot, Garden City Publishing Co., Inc., Garden City, New York, copyright 1943 by Book Presentations, New York, and page of The Wise Encyclopedia of Modern Sewing, Wm. H. Wise & Co., Inc., New York, 1950, copyright 1947, 1948, 1949, 1950 by Wm. H. Wise & Co., Inc.
The machine parts being in their normal inoperative positions as shown in full lines in Fig. 3 and in dotted lines in Fig. 2, the first preliminary operation may be the forward or rearward adjustment of the work support and work supporting shoes II, II to set the work margin abutment flanges 55 at such predetermined distance from some fixed or datum point circumferentially about the axis of shaft H, as will result in placement of some particular point on or part of a pinhook at that distance from the top marginal edge of the drape heading as will give the drape its support at the desired line. The scale markings and index plate E'I may be graduated and arranged to determin the desired position of the work stops 55. Upon release of the clamp knob 22 the adjustment knob 35 may be rotated in one direction or the other to turn the shaft I? through operation of the worm 32 and worm gear 26 thereby to swing the support base I8 and the work support shoes 4i, GI forward or backward until the index plate 57 registers with the desired mark on scale 55. Thereafter the clamp knob 22 is again tightened to secure the setting.
The next step may be the adjustment of the slot width between shoes ll, 4!. If the drapery plaits are all of the same general type and transverse thickness, only one transverse setting of the shoes may be required to provide the correct slot Width for disposition of all of such plaits therein so that it is not necessary to readjust the slot width until a thicker or thinner plait is to be pinned. Adjustment of the slot width is readily accomplished by rotation of the knurled knob It which, through the oppositely threaded portions of shaft t6, simultaneously moves both work support shoes 4!, 4| toward or from one another along guideways 3'I38. The slot width preferably is such as to furnish a firm but light pressure on the material at opposite sides of the plait but the lips of the projections 52, 52' should not be so close together as to interfere with the insertion or placement of the pin point and shank of a pinhook.
Grasped by hand along a portion of the upper part of the plaited drape with the rear, or reverse side of the drape upward, the upper edge is thrust over the surfaces of the work support shoes il, ill with the plait to be pinned depending into the slot and with the material at each side of the plait disposed downwardly and outwardly over the inclined upper surfaces 53, 53' and the cylindrical surfaces 5i, iii of the work shoes after the manner illustrated in Fig. 6. The upper edge of the drape is brought up evenly against the adjacent faces of the work stops 55.
With the work so placed on the work support the operator depresses the foot treadle which, during the first part of its movement, permits the setter head to lower by action of gravity until the work clamp feet 8| make firm clamping engagement with the work, the feet 8| pressing the work against the sloping or inclined surfaces 52, 52. The depression of treadle 99 urges the connecting rod upward thereby swinging rocker arm 8! in a counterclockwise direction, viewing Fig. 2 from the dotted line position shown in that figure toward the full line position. As the rocker arm starts this swing carrying the crank HM with it, the shaft 12, being attached to crank Hi4, drops down the slot H37 and the entire setting head 84 carrying the fabric clamp 79 drops with it. The slot 183, of course, permits freedom of movement of the crank arm within limits with respect to the rocker arm since the rocker and crank arms have difierent swinging radii and other differential movements. During the first part of the depression of treadle 99 then, the fabric is clamped to the work support. but there has been little if any rotative movement of the shaft l2, lever arm H and pin-setter arm 69 as Fig. 5-A indicates. However, at this time a pin-hook will have entered the slot and been disposed as shown over the reduced end of setter arm.
It will be helpful to an understanding of certain functions performed by the setting mecha nism, to digress momentarily from the statement of operation to describe the type of pin-hook employed with the machine of the instant embodiment. The pin portion of this pin-hook normally is closed against the hook portion as shown in Figs. 5-A and 8-A. As most, clearly illustrated in the latter figure, the hook portion H is a loop somewhat of horse-shoe shape since the loop ends are curved in toward one another while the shank part S of the pin portion is bent back rather sharply at one side of the hook loop so that it is substantially tangent to the outer side of the loop of the hook portion, as indicated at C. Whether the shank portion actually makes contact with the loop of the hook portion or merely extends in close proximity thereto generally is not of material consequence so long as the gap between these portions at C is sufficiently narrow and the pinhook wire has a degree of resilience or spring quality suificient to offer resistance to the escape of the fabric from within the small loop betvveefi such portions. The shank portion terminates in the usual point P. The opposite or free end of the hook portion H terminates in an outwardly flared nib F which is designed primarily to facilitate engagement of the hook over drapery supports such as rods and by reason of this flared part the pin-hook has greater transverse width at this place than the transverse width at any other section. Advantage is taken of this last mentioned feature of the pin-hook to aid in opening a gap between the pin shank portion S and the hook portion H at point of tangency C to permit easy entry of the pinned material therebetween into the small loop, the natural resilience of the pin-hook wire being relied upon again to close the pin shank. portion against or toward the hook portion upon passage of the pinned material past the gap into the small gathering loop.
As will be seen upon inspection of Figs. LA and 5-33, the opposed and abutting projections 14 of the housing members are cut away at the juncture of the radially angular edges 15' with their arcuate walls 10, as indicated at Hi, to permit the nib- F free entry into the pin-hook guide slot 68 over the end of setter arm 69. However, since the radial width of the remainder of the guide slot. between the arcuate wall '10 and the opposed outer wall of such slot is less than the transverse width of the pin-hook thereacross at the nib F, movement of the pin-hook into such narrower part of the slot under impetus of the setter arm 69 will cramp the pin-hook transversely causing the nib F to be moved resiliently toward the opposite side of hook portion H. It will also be noted in these Figs. 5-A and 5-3 that the housing members $1, -61 terminate in a plane parallel to a tangent or substantially parallel to a tangent to the upper edge of the arcuate lips of the work support projections 52, 5.2 substantially at the mean of the pin shank length so that, when the setter head is in its down position, as shown, the terminal surface 86 becomes substantially tangent to. the arcuate edges of the work support lips and the pin-hook guide slot is opened on its outer side for emergence of the pin shank portion S including point P.
Therefore, as the treadle 9Q is further depressed beyond the point above mentioned, the radial lever arm H swings in a clockwise direction (Figs. 5-A and 5-B) from the position in Fig. 5-A to that in Fig. 5-B, causing the setter arm 69 to move the pin-hook with which it is engaged into and along the confining part of the guide slot with the nib F compressed toward the opposite side of hook portion H. When the pin-hook reaches that portion of the guide slot which is open at the outer side thereof the pin point P followed by the succeeding increments of the shank portion S will spring or tend to spring radially outward away from the adjacent parts of the hook portion H thereby opening the pin to provide a gap at C to permit passage of the material therethrough into the gathering loop atthe junction of the shank portion S with the hook portion H. The emerging point of the pin-hook will be inclined downward toward the material with which it is to engage and into which it is to be inserted but will continue to be swung in an arc. The result is that the pin point and the balance of the pin shank will enter the material or the seam of the fold or plait and come to rest (upon completion of movement of the setter arm 89) in the position illustrated in Fig. 5-3 and Fig. 6.
Upon release of the treadle 99, the spring ID! will return all of the operating parts of the machine to their initial inoperative positions the inserted, pin-hook, of course, remaining where placed in the material. As soon as the setter arm returns to the position shown in Fig. 5-A the magazine mechanism operates to place the next pin-hook over the receiving end of the setter arm which, until such position is attained serves to obstruct the entry of pin-hooks into the guide slot. With the return of the setter head to its uppermost or inoperative position, as in Fig. 3, the fabric clamp is raised away from the material to. permit the drape or other work to be removed.
The invention has been described and illustrated in a presently preferred form for a particular purpose but, as will be appreciated, it is susceptible of embodiment in other forms and for other purposes and many variations in construction and arrangement may be made. Consequently, I desire to be limited only by the invention spirit and the scope of the appended claims.
