GARMENT-CUTTING APPARATUS.

Specification of Letters Patent.

Patented July 1141, rate.

Application filed December 1, 1911. Serial No. 663,339.

To all whom it may concern:

Be it known that I, Gnonon M. LAUB, a citizen of the United States, and a resident of the city of Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Garment- Cutting Apparatus, of which the following is a specification, reference being had to the accompanying drawings. This invention particularly relates to that class of cutting devices which may be manually caused to traverse a pattern, and which is provided with a relatively movable cutting tool, mechanically actuated to cut or perforate a plurality of layers of sheet material.

The principal objects of this invention are to provide a device of the class decutting a plural ity of thicknesses of sheet material such as cloth, paper, leather, etc., which, if desired, may be securely fastened to the surfacecf an operating table; to provide a cutting device which is capable of free movement over the surface ofthe material, and which is adapted to cut in any direction either forward or backward; to provide a cutting device which may be operated so as to begin cutting at any point on the surface of the material without the necessity of beginning the cut at some point at the edge of the cloth; and to provide a cutting device with guiding means, which, in connection with a pattern or templet placed upon'the surface of the material to be cut, will'assure an accurate adherence to the design which is desired to produce, thus relieving the operator from the nervous and bodily strain inherently incident to guiding a cutting'device along marked lines for longperiods of time.

Further objects of this invention are to provide means whereby a garment cutting device may besuspended over the work table, and whereby the weight of the apparatus is entirely supported; thus freeing the operator from the necessity of exerting much physical effort'in order to move the device over the layers of material to be out; and to provide a garment cutter in which the knife is designed to out either forward or backward with respect to said knife; and toprovide means for variably adjusting the pressure exerted downwardly on the materiahby the cutting apparatus, since it is 'tor desires to produce.

desirable toalter such pressure when operating on various sortsof material.-

This invention also comprehends all of the various novel features of construction and arrangement hereinafter more definitely specified.

In the accompanying drawings, Figure l is an elevation of the complete garment cutting apparatus; Fig. 2 is a vertical transverse fragmentary section taken on the line 2-2 of Fig. 1; Fig. 3 is an enlarged elevation of the cutting device, shown partly in vertical section for conveniently showing its actuating mechanism; Fig. 4 is an enlarged fragmentary view of the knife actuating plunger shown in vertical section; Fig. 5 is a horizontal section taken on line 55 in Fig. 3; Fig. 6 is a horizontal section taken on line 66 in Fig. 3; Fig. 7 is a horizontal section taken on line 77 in Fig. 4'; Figs. 8 and 9 are elevations of alternate forms of knives which may be employed in connection with the cutting device shown in Figs. 1 and 3; and Fig. 10 is a horizontal section of said knives taken on lines 10-10 in Figs. 8 and 9.

Referring to the drawings, 1 represents a table or other suitable support for the material 2, which it is desired to cut, and which is laid smoothly thereon and preferably fastened firmly thereto by any desired clamping means, said means not being shown in the drawings. On the upper surf-ace of the said material is preferably laid a pattern or templet 3 which can be constructed of any desired material, such as card board or thin fiber and the outline of which corresponds to the shape of the pattern which the opera:

also be firmly secured in position, ably by the same clamping means which are utilized to hold the goods. v

Suspended from the ceiling 6 by the bracket 7, are the track rails 8. The brackets 7 are secured to'the ceiling bythe lag screws 9, and are preferably formed in a channel or U-section, the open sides of the channels being turned inwardly in such a. manner as to be mutually opposed as best shown in Fig. 2. The track rails 8 are preferably formed-With one edge beveled, and are secured to the brackets 7 by the bolts 10 in such a manner that the beveled portions of the track rail project over the opti sides of the channels in the brackets 7 This templet may;

prefer- Mounted upon the horizontal plate 12 are the roller supports 13 and 14 which are se cured to the said plate 12 the bolts 15, and which furnish support for the spindles 18 on which are revolubly mounted the inwardly beveled rollers 19. The spindles 18 are secured to the supports 13 and 14 in any desired manner. In the construction shown, the spindles pass through horizontal holes properlysituated in the supports 13 andl4, and are held in position by the nuts 21 which" engage with the threaded inner ends of the said spindle, as best shown in Fig. 2. It will be understood that the eight rollers 19 are symmetrically placed with respect to the plate 12, and that the description of the mounting for one of the said rollers covers the similar mountings for the other seven.

Secured to the underside of the plate 12 by the bolts 28, is tlle vertical supporting rod 29,which extends downwardly from the said plate. At its upper end, this rod is provided with a flange 30 through which the bolts 28 pass and which serves to afford a means for firmly securing the supporting rod to the plate 12.

g A collar'32 surrounds the supporting rod 29 and is secured thereto by the set screw 33. Downwardly extending braces 34 extend from the corners of the plate -12 to this collar. These braces are formed in pairs in asort of V-shape and have feet on the upper ends, affording means to secure the upper ends of said braces to the supporting plate 12 by the bolts 35 which pass through suitable holes in the plate and the feet. That portion of the V where the two arms intersect is formed into a lug 36 which rests against the collar '32 and is firmly secured theretoby the screw 37 which passes through a suitable hole in the lug and engages in a threaded hole in the collar 32, a similar construction being used for the diametrically opposed brace on the other side of the collar. At the lower end of the supporting rod 29 is provided-the horizontal collar 40, which drical aperture aforesaid 1s firmly secured to the said rod by means of the set screw 41. The upper surface of this collar is slightly hollowed or grooved forming a race-way for the ball bearing 43 Y on which rests a suitable portion of the bracket 44. This bracket is formed preferably in the manner shown in Fig. l, which may be described as being in the form of a semi-inverted L, that portion of the bracket corresponding to the base of the B. being preferably circular in horizontal section and having a central cylindrical aperture. the sup the bracket '44 thus being free to revolve horizontally around the said rod. That portion of the bracket adjacent the lower end of the cylinis hollowed out slightly to provide the upper race-way of the ball bearing 43. The bracket 44 is also preferably provided with the yoke 47 dependent therefrom and to which is secured an electric motor 48 by suitable bolts 49, which pass through holes in suit-able portions of the yoke 47 and through corresponding holes in the base of the motor 48 and are fitted with nuts 50. The yoke 4:7 is designed to support the motor 48 in such manner as to bring its greatest weight directly on the axial line of the rod 29, so that'the weight is evenly distributed on the ball bearing 43.

The outer end of the bracket 44, considering the rod 29 as a center, is provided with a boss 53, the-lower face of which is circular in form. Through a. suitable hole in the boss 53 passes the vertical pivot bolt 54, which is provided with a head 55 to keep it from falling through-the hole. On the lower portion of this bolt, which extends below the face of the boss 53, is revolubly fitted another boss 58, which is practically similar in form to the boss '53, but which is fitted upon the bolt 54 in an inverted position and is secured thereon by the collar 59, which fits upon the lower end of the bolt 54 and which is held in position by the set screw 60. Between the two opposed faces of the bosses 53 and 58, is provided a ball bearing 61, the faces of the bosses being suitably hollowed out or grooved to provide race-ways for the balls.

The horizontal arm 62 extends outwardly from the boss 58, being integral therewith, and has firmly affixed to its outer end the boss Through a suitable hole in this boss passes the vertical pivot bolt 64, which is provided with a head 65. Another boss (56, practically similar in all respects to the boss (53, is held in opposed inverted relation to the latter by means of the bolt 64 which passes upwardly through a suitable hole in the said boss 66 and through asuitable hole in the boss 63. A collar (37 is secured upon the upper end of this bolt -by set screw (58. Betwe-en the two opposed faces of the bosses is provided the ball bearing (39, said faces being suit-ably hollowed out or grooved to provide race-ways for the balls.

It .will be understood that the construction just described is in allrespects practically similar to the construction of the bosses and ball bearings on the end of the bracket 44, except that the bolt 64 passes through its respective bosses in the opposite direction to that in which the bolt 54 passes through its respective bosses. In practice, it is preferred to make the bolt 54 a tight fit in the boss 53 and a working fit in the boss 58, and the bolt 64 a tight fit in the boss 66 and a working fit. in the boss 63.

Extending outwardly'and downwardly in a curved direction, as shown in Fig. 1, from the boss 66, is the arm 70, the outer end of toned by means of which tcrmimites in a boss 71 preferably of cylindrical form. A. vertical plunger 72 slidably passes through a suitable aperture in the said boss 71. At the upper end of the plunger 72 is pivoted the link 73 by means of the horizontal pivot 7-1 and to the upper end of this link is similarly pivoted the beam 75 by the horizontal pivot T0. Near its center, the beam 75 is provided with a longitudinal aperture through which passes the arm 70.

The beam 75 is pivoted to the arm by means of the pivot 78 which passes through suitable apertures both in the beam and in the bracket 70, and which is provided on one end with an integral head and on the other with suitable threads on which is secured a nut. lVashers T9 are preferably placed between the aforementioned head and nut and that portion of the beam adjacent thereto. The end of. the beam opposite to the link 73 is provided with an adjustable weight 80 which may be secured in any desired adjusted position by the set screw 81.

he lower end of the plunger 72 is provided witha flange to the under-side of which is firmly secured the casing 86 by the bolts 87. This casing, which is preferably rectangular in horizontal section, is constructed in such manner that one side 88 may be readily removablo to permit free access to the mechanism inclosed therein, said removable side being preferably secured by the bolts 89. I

Within the case 86 is a crank shaft 90 which has its ends reduced in section and suitably journaled in bearings 91 and 92 provided in the walls of the casing, the hearing 91 being preferably located in that side if the casing which is removable. of the crank shaft journaled in the bearing 92 extends through the casing and may be connected by a. suitable coupling 93 to the flexible shaft 91, of any well known construction, tending upwardly and connected to the motor 48. This flexible shaft may be supported, if desired, by a book 95 attached to a wire 96 which is secured to a lug 07 upon the bracket 1-1.

The crank shaft 90 is provided with a connecting rod 100 which embraces the eccentric portion of the crank shaft, and is secured thereto in a well known manner by means f the cap 101 and the bolts 102. The connecting rod 100 is einln'aced at its outer end by. a bifurcated portion of another connecting rod 105 to which it is pivotally fasthe pivot 106 which passes through suitable holes in the bifurcated end of the connecting rod 105 and a similar hole at the end of the connecting rod 100, and which is secured in position by the nut- 107. 1

The lower nd of the connecting rod 105 is provided with an integral ball which, in

The end.

connection with a ca 108 and the base 109 forms a ball and socket joint in the Well known manner. The cap 108 is secured to the base 109 by means of the bolts 110.. The lower portion of the ball and socket joint namely, the base 109 is integral with the cylindrical lunger 112 which extends downardly therefrom. Surrounding said plunger 112, is the sleeve 113 in which the said plunger forms a snug working fit. The upper portion of the said sleeve is provided with an integral flange 11s, the upper face of which rests against the lower side of the bottom of the casing 86,

.1 collar 116 having a c ntr l cylindric l hole of a size to permit the sleeve 118 to pass therethrough and form a snug working {it therein, is secured to the underside of the casing 86 by the bolts 117. The upper part of the hole in this collar is enlarged in di ameter in such manner as to snugly receive the. flange on the upper portion of the sleeve 1.1; so that when the collar 116 is secured in position. on the casing, the sleeve 113 extends downwardly therefrom and is held firmly in position against the lower side of the casing 86, without however preventing it from being capable f rotation around its axis.

Diametrically opposed to each other on the outside of the sleeve 113 are provided the two vertical feathers 120, 121 which extend longitudinally along the sleeve for a considerableportion of its length. Near the lower endof the sleeve 113 is provided a 100 small set screw 12% which is screwed into a suitable threaded hole in the sleeve 113 and 1UjCtS from the inner surface of said sleeve into a suitable longitudinal slot 125 rovided in the lower portion of the plun- 105 err 112 as best shown in Figs. 4' and 7. The object of this set screw is to prevent relative rotation between the plunger 112 and the sleeve 113, while permitting free movement of the plunger within the sleeve along j-cto its axial line. p

The lower end of the plunger 112 is provided with an upwardly extending rectangular slot which is formed of proper dimensions to snugly contain the upper portion of a knife 130-. Surrounding the lower end of the plunger 112 is a collar 131, and in a suitable threaded horizontal hole provided in. this collar and also through a correspond.- ing hole in the lower end of the plunger 112, the thumb screw 132 is arranged to pass, so that When the knife 130 is inserted in the rectangular slot provided therefor in the, lower end of the plunger 112, and the thumb scrcw132 is screwed inwardly to a sutlicient distance. the knife will be held firmly in fixed relation to the plunger.

31 knife guide 110 is provided which is of peculiar conformation, as best shown in Figs. land 3.

The upper portion of this guide extends for a short distance in a horizontal direction and is provided with a vertical cylindrical aperture which forms a good working fit upon the outside of the sleeve 113. Diametrically opposed key-ways 1%1, L12 ar provided, extending outwardly from the inner surface of the cylindrical aperture aforesaid, to permit the passage of the keys or feathers 120 and 121, as best shown in Fig. 6.

On the outside of the portion of the guide 110, which embraces the sleeve 113 is provided a lug 14.3, which has a vertical saw cut extending th'erethrough, and at right angles to this saw out extends the horizontal bolt 1-14 which is secured in the lug for a short distance near its head,,and which eX- tends freely through the remainder of the lug. Said bolt is provided at its other end with screw threads to accommodate the wing-nut 145, so that by tighteningthe said;

wing-nut, the diameter of cylindrical hole in the knife guide 140. may be constricted and the guide 1-10 thus clamped in any position desired upon the sleeve 113, and by loosening the said wing-nut, the guide 140 may be adjusted up and down upon the said sleeve. A Washer 146 is, in practice, preferably inserted between the Wing-nut and that part of the surface of the lug upon which it bears.

The knife guide 140 extends substantially downwardly from the portion thereof'just described, and at its lower end is provided with an upwardly extending recess forming a sort of fork in which is located the presser roller 150. This roller is mounted upon the horizontal spindle 151, which passes through the roller and upon which it is free to revolve. This spindle is preferably made in the form of a bolt having threads upon the end opposite its head 152 which engage in a suitable threaded aperture in the knife guide as best shown in Figs. 3 and 5.

Adjacent that side of the roller 150 nearest the axial line of the plunger 112, the knife guide is provided with a downwardly extending lug 155 so formed as to project slightly below the lowerface of the roller 150, and to readily engage, when the machine is in operation, the profile of the templet 3. A suitable slot 156 is provided in the knife guide 140, which is extended forwardly on either side thereof, as best shown in Fig. 5, in which the knife blade'l30 is free to vertically reciprocate. This slot is preferably made of a sufficient width to readily accommodate the knife 130, and to permit its reciprocation therein but not wide enough to allow any lateral bending of the knife blade. The knife guide 140, is also provided with the handle 162 on the right hand side of the knife when the machine is viewed in the position shown in Fig. 1, and on the opposite side of the knife with the thumb piece 163.

These projections are so formed as to afford a ready hold for the operators hand.

the point is rounded, which is found, in

practice, to be more effective on certain sorts of material. Both forms of knives are sharpened on each of their side edges, or in other words are double edged, for a con-' siderable distance from the point, as illus trated in Fig. 10, where a horizontal sectional view is shown. The upper portion of the knives are formed with rectangular sections adapted to engage in the slot in the end of the plunger 112. It will be understood that other forms of knives may be employed, k

for" instance a rotary knife, or a knife for cutting separate perforations. To the supporting plate 12 is attached on either side cords 170 and 171, which pass over suitable pulleys 172, and terminate in handles 17 3 in.

convenient position for the operator, thus permitting him to readily move the plate 12 along the trace rails by pulling on the handle. The pulley and handle for the cord 171 are not shown, but they may be located in any convenient position in a manner similar to the pulley and handle of the cord 170.

:The operation of the garment cutting apparatus is as follows: The material being secured to the table as already explained,

and the templet 3 being clamped to the upper surface of the goods, the guide 136 is brought in contact with any portion of the profile of the templet. The wing-nut 145 is loosened and the knife guide adjusted vertically in such manner that the point of the knife 130, when in its lowermost position,

will reach the surface of the table 1 when the presser roller 150 is resting on the upper surface of the templet. The desired position of the knife guide being ascertained, the wing- Ilut 145 is tightened, thus clamping the knife guide in position and the power turned on to the motor 48. The knife 130 at-once thumb on the thumb piece 163, is able tomove the knife guide around the edge of the templet 3 in any direction which he chooses, the flexible arms of thesupporting means afiording' perfect freedom of movement in any direction and the double edge knives being operative to out either forward or backward. The pressure of the pre'ss'er roller 150 upon the surface of the templet may be regulated by sliding the weight 80 along the beam 7 5, it being found desirable, in practice, to vary the pressure according to the different materials upon which the machine has to operate. If, owing to the extent of the pattern which it is necessary to cut, it is found desirable to move the plate 12 along the track rails, which extend preferably longitudinally of the cutting table 1, such movement may be readily accomplished by a pull on the handle 173.

It 1s not desired to limit the scope of this invention to the precise details of construction as set forth in this specification and the appended claims, since it is obvious that various changes and modifications can be made therein without departing from the spirit or scope of the invention.
