8 Claims.

This invention relates to gauges for use in connection with sewing machines of the single head or multiple head types, and particularly for use in guiding automobile interior trim panels or the like through the machine'during the operation of stitching together the materials of the panel.

I Heretofore it has been necessary to guide the trim panel by hand and inasmuch as it is desirable to 1 provide several rows of stitches located in predetermined spaced relation, it has required the services of skilled operators to guide the panel through the sewing machine so as to produce straight, as well as parallel, rows of stitching.

The trim panel or panels lend ornamentation to V the interior of a vehicle body, and for this reason it is important that the stitching extend in straight rows and that the rows be equidistantly spaced or parallel since any variation or irregularity in an individual row of stitching or any unevenness in the spacing apart of the rows is easily discernible. It will be obvious that such proper application of the rows of stitching is difficult and it was often necessary, with the old hand method of feeding and guiding the panel, to rip out entire rows of irregular stitching and to re-stitch the panel.

It is, therefore, an object of my invention to provide means for accurately guiding a trim panel through a sewing machine in a predetermined straight line path so that the stitching applied to the panel will bein a straight line and so that the several rows of stitching will. be properly and equidistantly spaced one from the other.

Another object of my invention is to provide improved means whereby a row or rows of stitching may be applied to a panel in predetermined positions, and further to provide guide means which is easily and quickly adjustable by the operator so as to permit the application of the row or rows of stitching at different predetermined locations on panels of varying sizes and shapes.

7 Another object of my invention is to provide indexing means for the panel guide means, thus permitting accurate adjustment of the panel with relation to the stitching .head or heads of thesewing machine.

A further object of my invention is to provide adjustable guide means for sewing machines having a battery of stitching heads together with adjusting means for the guide or guides permitting the accurate adjustment thereof by the operator without the necessity of handling the 55 guide means itself.

Another object of my invention is to provide adjustable guide means of the foregoing char acter capable of permitting accurate adjustments atwill to accommodate different panels of varying sizes and shapes so that the operator, by

movirig the indexing mechanism to a new position, effects the relocating of the guide means within a relatively wide range to accommodate the different panels to be stitched.

Another object of the invention is to provide guide means which is capable of adjustment by a remote control device located within easy reach of the machine operator.

Another object of my invention is to provide improved guide adjusting means for use on various sizes of sewing machines wherein one or a plurality of panels are being fed through the machine and wherein one or more guide members are employed.

Another object of my invention is to provide improved adjusting means ofthe foregoing character having indexing mechanism provided with means, such for example as symbols, for identifying or indicating the various positions of adjustment.

The above and other objects of the invention will appear from the following descriptionand appended claims when considered in connection with the accompanying drawings forming a part of this specification.

Before explaining in detail the present invention it is to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanyingdrawings, since the invention is capable of other embodiments and of being practiced or carried out in various'ways. Also it is to be understood that the phraseology or terminology employed herein is for the'purpose of description and not of limitation, and it is not intended to limit the invention claimed herein beyond the requirements of the prior art.

Referring now particularly to Figs. 1 to *5 inclusive of the drawings, there is shown one form of guide means and indexing mechanism therefor embodying the present invention. This particular form of the invention is adapted for use in connection with sewing machines of the multiple head type, one unit thereof being shown as a whole at A-in Fig. 1. The machine, of which only a portion is shown in the drawings, consists of a flat horizontal bed l5 along which the material or work B, such for example as an interior trim panel for a vehicle body, is moved either by hand or by suitable conveyor chains (not shown) to be stitched by the sewing machine head mechanism A. The head or unit A including needle carrying and actuating mechanism for applying the threads C to the trim panel B, is preferably carried by a bridge 3 extending transversely above the bed of the machine. The head includes a pair of needles I! mounted upon a needle bar [8 which is vertically slidable in the needle guide bar H! which extends up to the mechanism for actuating it. The needles I! extend into the material or panel B through slots formed in the presser foot 20 and as the panel B is moved relative to the presser foot, two parallel rows of stitching D are applied to the material. I have described merely a portion of the sewing machine mechanism for the reason that the sewing machine per se forms no part of the present invention, the same being more fully described in my co-pending application Serial No. 70,345, filed March 23, 1936.

In Fig. 1 it will be seen that an adjustable guide bar or strip 2|, preferably formed of hard wood andhaving a reenforcing metal angle strip 22, is mounted upon the top of the bed l5 and extends lengthwise thereof adjacent but slightly spaced from the left hand edge of the sewing machine unit A, see Fig. 1. As shown in Figs. 4 and 5, the vertical flange of the reenforcing angle 22 engages the outer face of the bar 2! and screws 22a are provided to secure the reenforcing angle in place. This guide strip 2| is adapted to be adjusted into various positions relative to the the line 'and calculations so as to set the guide at the proper location for the particular work piece upon which the machine is operating. For example, if the machine has been operating upon a series of trim panels for the front door of an automobile body and it is desirable to then run through the machine a series of panels for the rear door or for a rear quarter portion of the body; it is necessary to change the adjustment and the position of the guide bar 2| which has to be correspondingly adjusted at both of its ends. It is an extremely diiiicult operation to effect such adjustment in accordancewith previous practice and it will be understood that any variation or mistake in the adjustment of the guide member will cause the machine to produce imperfect work.

In Figs. 1 to 5 inclusive I have shown one form of indexing mechanism or device for effecting a quick, easy and accurate adjustment of either one or both ends of the guide bar 21. In the instant form of the present invention, as shown, the bed I5 is provided with a rectangular pocket or recess 23 in which is set a metal plate 24 held in place by screws 25 upon which is mounted a second metal plate 26 of smaller size than the plate 24 and which serves as a spacer and supporting base for a third metal plate 21, the plate 21, as shown, being somewhat thicker than the plates 24 and 25. These three plates together provide a platen and are secured together in any suitable manner as by means of screws having countersunk heads or by welding or soldering, as desired. As best seen in Figs. 1, 4 and 5, the plate 27, in addition to being somewhat thicker than the plates 24 and 26, is wider than the plate 24 and thus its longitudinal side edges overlap the corresponding edges of the plate 25, these overhanging portions providing flanges 21a which are spaced from the base plate 25 for a purpose to be hereinafter described. As seen in Figs. 3 and 4 the plates 24, 26 and 2'! are provided with vertically alined holes or apertures 28. The apertures are preferably staggered and beside each on the top of plate 2'! is an identifying symbol, such as the letters a, b, c and d, see Fig. 2. If desired, a single plate or platen having a thickness which corresponds to the combined thickness of the plates 24, 26 and 21 may be employed.

In Fig. 2, the base plate 24 is provided with a pair of slots 240. through which the attaching screws 25 pass. Since the plates 24, 26 and 2'! are all secured together as a unit, said unit can be moved lengthwise in the recess or depression 23 toward and away from the inner end wall of the depression and the guide bar 2! by loosening the screws 25 and sliding the base plate along. Thus the base unit or platen of the indexing mechanism provides a wide range of adjustment so that the sewing machine may be employed to perform work on trim panels having a wide range of sizes.

The indexing mechanism includes also an adjusting member or block 38 formed preferably of some sort of malleable metal capable of being readily drilled to produce spaced holes or apertures 3| to receive and support a removable loeating pin 32. The vertical holes 3|, as seen in Fig.2, extend in a row transversely of the block and each is identified by a different symbol, such as the letters a, b, c and dwhich correspond to similar letters which mark the holes 28 in the plate 21. The block 30, as shown, has along its side edges flanged metal plates or strips 33 provided at their under sides with inturned flanges 34 which underlie and are spaced from the bottom of the block 30, see Figs. 4 and 5; The plates 33 are held in place upon the sides of the block preferably 'by screws 35 having countersunk heads.

I The block 30 is applied to the top plate member 21 of the base unit by inserting the flanges 34 under the side edges or flanges 21a and sliding the block over the base piece 21. The parts are made to have a sliding fit so that the block 30 can be moved longitudinally over the base members or unit but cannot be'shifted laterally relative there-' to,.thisfor the reason that .the holes 3| in the block 30 must be alined with certain of the holes 26 formed in the plates 24, 26 and 21 in order that the removable locating pin 32 can be shifted from one set of vertically alined holes to any other set of similarly alined holes in the several members. As shown, see particularly Figs. 2 and 3, the block 33 is adapted to move with the guide bar'and is attached directly to the guide bar 2| by means of a metal angle piece 31, the horizontal flange of which is secured to the top face of "entwork pieces.

the block 30by screws 38, the vertical flange in each block and sliding the blocks 30 over the plates 21. As shown in Fig. 1, one of these indexing devices is .provided for each end of the guide bar 2|, the devices being located a short distanceinwardly from the ends of the bar. Each of these indexing devices is identical so that by moving the indexing pins 32 to like positions in the two blocks 30, like adjustments of both ends of the guide bar are effected. The holes 28 and 2| formed in the plates 24, 26 and 21 and the slidable block 30, respectively, are located at predetermined positions, each with a view to adapting the guide bar for use in guiding the edge of trim panels 'of different sizes and also different shapes. By predetermining the positions of the holes and by numbering or lettering the top of the block 30 adjacent the holes 3|, as by'using the letters a, b, c and d, and correspondingly lettering the holes 28in theplate 21, an unskilled operator can shift the block. 30 and relocate the index pin 32 in any chosen and like lettered holes,'t:such as in holes b. b, so as to adjust the guide bar tosult differ- 7 By virtue of the indexing mechanism with its predetermined and symbolized ad'- justment effecting positions, itis unnecessary to" have to take any measurements whatsoever to effect the proper adjustment. If the base'blocks I or plates 24, 25 and 21 do not have a sufllcieni number of adjustment holes for a given variation in workpieces, it is merely necessary to drill additional'holes in the plates and,ifnecessary,-to

add other holes to the slidable block 30 so that a wider range of adjustments can be effected: for

use in connection with additional work pieces of varying dimensions. Such additional holes would, if desired, be identified in the same manner as the holes 28 and 3|. A number of surplus base plate units may be kept in stock so'that in the event a wider range of adjustment of the guide bar 2| is desirable, a reserve indexing base plate unit or a pair of such units can be substituted for those on the machine bed. While the various base plate units contain different arrangements of symbolized holes to receive the indexing pin, they are all of the same proportions so that they may be interchanged at will.

Referring now particularly to Figs. 6 to 8 inclusive there is shown a somewhat modified form of indexing mechanism embodying the present invention. In this form the indexing mechanism also serves as means for guiding the work pieces, such astrim panels, through the sewing machine and is particularly adapted for use with a single unit sewing machine of the bracket-arm type wherein the work pieces are moved by hand over the bed of the machine and wherein the space under the machine is limited. Referring especially to Fig. 6 there is shown asa whole at E a sewing machine of the so-called bracket-arm type in which the machine is mounted upon a metal base 40 supported upon a table or bed 4| provided with upright legs 42.

The combined indexing and work guiding mechanism or device of the present embodiment of the invention is mounted upon the metal base 40 beneath the horizontal arm of the machine E and comprises preferably a rectangular metal base plate 43 provided adjacent its left hand corners with slots 44 through which machine screws 45 are passed to secure the plate to the base 40 and to permit its adjustment longitudinally over the base. Mounted substantially centrally of the plate 43 is a relatively long and narrow metal plate or strip 46 upon which is mounted a second metal plate 41 preferably of the same length as the plate 46 but of slightly greater width so that its longitudinal edges 41a project beyond the longitudinal edges of the plate 46 to provide, in effect, flanges which are spaced from the bottom plate 43 (see Fig. 8) fora purpose to be described. The plates 46 and 41 are provided at predetermined spaced points with a plurality of vertically alined holes or openings 48. The plates 43, 46 and 41 are preferably secured together in flatwise relation by welding or soldering, or by machine screws or studs so as to provide a single unit in which the several plates are fixed against movement relative to one another. Mounted to slide upon the indexing plate 41 is a rectangular work piece guide block 49 having attached to its opposite lateral side walls,'metal plates 50, each provided with an inturned horizontal flange 5|. The plates, as shown, are held to the side walls of theblock 49 by means of screws 52. As shown, when the block 49 isassembled with the top plate 41-the flanges 5| engage beneath the flanges 41a and provide guides for maintaining the block against lateral shifting but permitting its longitudinal or approximately straight line movement or adjustment over the indexing plate 41, so that the holes or openings 53 formed in said block can be selectively alined vertically with the holes 48 formed in the plates 46 and 41. A removable indexing or locating pin 54 is provided for insertion in any one set of the series of vertically alined holes so that the movable block 49 can be maintained in any of its predetermined adjusted positions.

The combined indexing and guiding device of Figs. 6 and 8 inclusive is adapted for use in connection with trim panels or other work pieces of relatively small size, as well as to guide one edge of a panel of large size beneath the sewing machine head while stitches are being applied to one portion of said large panel. This device is used either prior to or after the said large panel has been provided. with a row or rows of stitching at different locations on the panel, it having been previously guided at its opposite edge by means of a remote control guiding and indexing device such as that described hereinafter and shown in Figs. 6 and 9 to 14 inclusive. Where the trim panels are of extra large size and consequently difficult for the operator to handle it is extremely helpful to be able to guide opposite edges of the panel at different times, dependent upon'the position at which the stitching is to be applied. As in the case of the form shown in Figs. 1 to inclusive, the entire indexing mechanism may be adjusted, as a unit, by loosening the screws 45 and shifting the unit along the base 40 and the minute adjustments for panels of different sizes and shapes is effected by withdrawing the index pin 54 and shifting it into one of the other holes 53 in the sliding block which is alined with another of the holes 48 in the indexing plate members 46 and 41. As in the preceding form of the present invention, the holes 53 in the block as well as the cooperating holes 48 in plates 46 and 4'! may be identified by different sets of numerals or letters or other indicia so that the operator will know how to make the proper setting and adjustment for the particular work piece to be guided through the machine.

Another form of indexing and guiding mechanism or device embodying the present invention is shown in Figs. 6 and 9 to 14 inclusive. This form of the invention is adapted for use with a machine such as the machine E and for purposes of convenience, is herein referred to as a remote control type of guide and indexing mechanism, wherein the guide bar or member is located at a point remote from the indexing mechanism, the latter being conveniently located adjacent the sewing machine head and in easy reach of the operator who is seated in front of the machine. As seen in Fig. 6, the guide member or bar is. located at the front edge at the left hand end of the bed or table 4| and is designated as a whole at F, whereas the indexing mechanism is located adjacent the right hand forward edge of the bed and is designated as a whole by the reference G. The details of the present form are best shown in Figs. 9 to 14 inclusive. Considering first the indexing mechanism G, it will be seen that an oblong base plate 55 is mounted upon the table 4| adjacent the right hand front edge of the table. The plate 55 has a limited range of longitudinal adjustment on the table through the medium of slots 56 through which the securing screws 51 pass. ly of this plate and extending lengthwise thereof is a second relatively narrow plate 58 upon which is mounted a third plate 59 of slightly greater width than the plate 58 so that its longitudinal side edges extend outwardly beyond the side edges of the plate 58 and provide, in effect, flanges 59a. which, as seen in Fig. 11, are spaced from the plate 55. The plates 55, 5B and 59 are preferably secured together in flatwise relation by electric welding or soldering orin any other convenient manner so that the three plates provide a unitary structure capable of longitudinal adjustment Mounted approximately centralwhen the screws 51 are released. The plates 58 and 59 are provided with a series of vertically alined holes or openings 60 which, as shown, are arranged in staggered relation, see particularly Figs. 9 and 10, for a purpose to be described. The holes of each series are provided with lettering or other symbols (not shown). At its right hand end the top plate 59 is provided with a stop or abutment 6|, see Figs. 6 and 9. The indexing mechanism includes a relatively long metal plate or strip 62 which is preferably the same width as the plate 59 and is of sufficient length to extend from the indexing mechanism indicated as a whole at G to the guide member F. In other words, the bar 62 extends between the indexing mechanism and the guide member and its left hand end is connected to and serves as a support for one end of the guide F, see particularly Figs. 12 and 14. A slidable block 63 is mounted upon the plate 62 adjacent its, right hand end and is located on said bar by means of an inverted machine screw 64 having its head counter-sunk in the member 62. Attached to the top face of the plate 62 to the right of and adjacent the block 63 is a pivoted indexing member or block 65 which is pivotally and oscillatably connected to the sliding plate 62 by means of a removable sleeve nut and cooperating bolt member, shown as a whole at 66. The block 65 is adapted to describe an are having its axis at the center of the threaded sleeve 66 and carries on its top face a metal plate 61 fastened thereto by screws 68. The block member 65 and plate 61 have alined vertical holes extending therethrough. The slidable metal strip 62 is provided with an arcuate slot 69 (Fig, 9) which is in vertical alinement with said holes when the block 65 is moved in its arcuate path about its pivot 66. The top face of strip 62 adjacent the slot 69 is provided with symbols (not shown) which correspond to those on the top face of plate 59 adjacent the holes 68. The purpose of the alined vertical holes and the arcuate slot is to receive and support a removable index pin 16 whose lower end is adapted to be inserted in any one of the holes or'openings 60 formed in the base plates 58 and 59 (Fig. dependent upon-the angular position of the member 65.

The block member 63 is maintainedin slidable relation with respect to the base members 58 and 59 and is prevented from lateral movement relative to these members, and from displacement during its longitudinal adjustment, by means of to permit easy and non-frictional sliding movement of the plate 62, block 63 and indexing member 65 over the plate'59.

At a point approximatelymidway between the base plate and the work guide F in its position of Fig, 6, the bed 4| is provided with a metal plate 15 and a spacing metal block or plate 16 which serve as supporting means, for the slidable member 62 to prevent it from sagging and thus facilitate its easy movement. v

.In Figs. 12, 13 and 14, the'details of the trim panel guide member F are shown. Adjacent the forward left hand end of the bed 4| there is provided a metal base plate or support 86 which is attached to the bed by screws or the like BI.

Mounted upon the plate 80 adjacent its front and rear longitudinal edges are metal strips or the slidable bar or strip 52 of the indexing mech anism overlies and is adapted to slide upon the plate 84. The plates 88, 82 and 84 are preferably secured together, as a unit, by welding or in some other suitable manner to provide a fixed base.

The plate or strip 83 supports a somewhat thicker metal plate or strip 85 which is somewhat longer than and projects inwardly beyond the plate 83 and is also of somewhat greater width than the plate 83 so that its longitudinal side edges overlap or extend beyond the corresponding side edges of the member 83 to provide, in effect, horizontal flanges 85a for a purpose to be described. The'strips or plates 83 and 85 are preferably welded together and to the base-plate 80 so as to provide a unitary structure. As seen inFig. 6, the plate or member 84 is provided with a stop or upstanding abutment 88 for the purpose of limiting the outward movement of the guide F.

The guide member F comprises, preferably, an oblong metal block 90 having secured to the top thereof a metal plate 9| whose inner longitudinal edge extends beyond the adjacent edge of the block 90 and is turned or flared upwardly at 92.

; The cover plate 9| ispreferably secured to theblock by means of screws 93 and the block in turn is secured at its forward end to the outer end of the sliding plate 62 by means of metal screws 94 whose heads are countersunk in the metal of the member 62. The forward end wall of. the block 98 is provided with a reenforcing member or guide plate 95 having at its lower edge an inturned flange 96. The plate is secured to the end face of the block by a screw .or screwsv 91. As seen in Fig. 14 the flange 88 engages under the flange 84a and .thus serves to hold -and guide the front end of the guide member in place so that it can travel with the slidable bar 62 over the fixed bar or plate 84. The cover plate 9| is attached to the block 90 adjacent its rear end by screws or bolts 98 which terminate short of the fixed plate 85 so that the block can slide over and relative to said plate. The inner or rear end wall of the block 90 is provided with a metal reenforcing and guiding plate 99 similar to plate 95 and has at its lower edge an inturned flange I00. The

, plate 99 is secured to the block end wall by means of a screw or screws IUI. As seenin. Fig. lithe flange I extends beneath and engages the under face of the flange 8511 thus serving to guide the inner or rear end of the guide member F as it is shifted by the sliding plate 62 over the fixed plate 85. Thus, the front and rear ends of guide block are held against lateral displacement and can slide freely over their respective supports 88 and 85.

The purpose of the flared inner longitudinal edge or lip 92 on the cover plate is to prevent the edge of a trim panel from becoming disengaged from the guide as it is being fed through the machine. The lip also facilitates the locating of the trim panel against the guide and thus speeds up the work of the operator.

As in the case of the preceding forms of the present invention the indexing mechanism of the present embodiment of the invention is provided with prelocated holes which may be designated by lettering, numerals or other indicia, as stated, to indicate to the operator and enable him to release the pin 54, shift the indexing blocks 63 and and move the guide F to a given predetermined-position for guiding a given size or style of trim panel or other-work piece through the machine, It will be understood that the plates 58 and- 59 can be provided with any desired number of holes or openings 80 in any desired locations, to receive the pin 10 so that any reasonable adjustment of the guide F within a relatively wide range can be effected, thereby materially increasing the range of sizes of trim panels or other work pieces capable of being stitched by the machine E, It will be understood that each symbol or pair of symbols are intended for use with a given size or shape of work piece or trim panel. Thus, the operator is enabled to set the guide accurately and promptly for the particular work piece to be operated upon.

As mentioned above in connection with the form of Figs; 6 to 8 inclusive, in the case of large trim panels I or other work pieces it is possible for the operator to employ the remote control guide device F and feed the panel through the machine to apply rows of stitching at certain predetermined points, to shift the indexing mechanism and also the guide F so that additional rows of stitching in predetermined parallel relation can be applied to the panel, and then, if necessary, to apply still other rows of stitching at different locations on the panel to complete the job, by turning the panel around to bring the opposite edge thereof into engagement with the block 49 of the combined indexing and guiding of Figs, 7 and 8 to complete the stitching of the panel. g
