4 Claims. (Cl. 1-49) The present invention relates to a dual stapling machine adapted to simultaneously drive two staples into a fabric, or other material, for marking or indicating specific pattern locations thereon.

In the sewing of garments, or similar articles, the various parts are frequently out to fit a paper, or other type of pattern, which indicates the shape and size of the individual garment section, and also designates the location of billtctons, button-holes, ornaments, tacking locations and the i e.

On most garment sections, the left and right-hand section are identical in shape and size, except for the location, when assembled into a finished garment.

The patterns are, therefore, made for the sections of one hand, so that both the left and right-hand section can be cut out simultaneously, by folding the fabric, and placing the pattern on the folded fabric plies.

In addition to cutting out the fabric sections, it is necessary to transfer from the patterns numerous points indicating the location of various points on each section, such as the location of buttons, button-holes, ornaments, and sewing and tacking points, so that these points will assume their correct position in the assembled garment, and the various parts will fit, as required.

Various methods have been evolved for locating these points from the pattern, but these have generally been unsatisfactory, as they either require a high degree of skill on the part of the operator, or the locations are indicated by chalk lines or similar media, which are removed or erased, in the process of subsequent handling of the garment parts, after the sewing operation is completed.

The object of my invention is to provide an apparatus, which will simultaneously mark locations at various points on left and right-hand garment sections from a pattern.

A further object is to indicate the locations in such a manner that when the folded fabric is opened, the various locations remain visible, until manually removed by the operator, after the garment section is completed.

A primary object is to provide a relatively simple, compact device, which will simultaneously drive a plurality of staples, or other type of marker into a fabric, in opposite directions in such a manner that they will retain their position, until manually removed, and will not injure or damage the fabric.

A primary object is to provide an apparatus which can be produced at low cost, and operated, serviced and I maintained by relatively unskilled personnel, over sustained periods.

The accompanying drawings, illustrative of one embodiment of my invention, and several modifications thereof, together with the description of their construction and the method of operation thereof, will serve to clarify further objects and advantages of my invention.

Fig. 13 is a partial plan view of the upper housing of the stapling apparatus of Fig. 1, and a partial longitudinal section through the body of the upper housing and the cavity formed therein.

Fig. 14 is a section through the case and the housing at the slot through the case wall, taken at 1414, Fig. 1.

It will be understood that the following description of the construction and operation of the dual stapling machine, is intended as explanatory of the invention and not restrictive thereof.

In the drawings, the same reference numerals dessignate the same parts throughout the various views, except where otherwise indicated.

The stapling machine, as indicated in Figs. 1 and 4, may be mounted in two housings, the upper housing 10 being pivotally attached to the lower housing 11, by means of a pivot pin 12, supported by a pair of side plates 13, attached to, or formed integral with the lower housing, as indicated in Fig. 1.

A stapling unit may be pivotally supported in each of the cavities 14 and 15, formed in the upper and lower housing, respectively, the narrow upper stapling unit 16, being pivotally attached to the upper housing by means of a pivot pin or screw 17, with the wider lower stapling unit 18, pivotally attached to the lower housing by means of a pivot pin 19, a screw, or other suitable pivot means, as indicated in Fig. l.

The housings may be made of wood, laminated wood, a plastic material, or cast, stamped and built up, or otherwise formed of metal, or other suitable material, the cavities 14 and 15, being molded in place, or cut out by other suitable means.

A plate spring 20, one end of which it attached to the upper surface of the solid portion of the lower housing by means of a plurality of screws or rivets 21, may be utilized to separate the two housings and stapling heads, and retain them in the open position, shown in Fig. 1, until the upper housing is manually pressed downward by the operator, to the stapling position, shown in Fig. 3.

A similar plate spring 22, may be mounted at the top of the cavity formed in the upper housing 10, one end of the spring being attached to the upper wall of the housing by means of a plurality of screws or rivets 23, the free end of the spring pressing against the top wall of the case 25, of the upper stapling unit 16, to retain the case in the free position, shown in Fig. l.

Another plate spring 28, may be mounted at the bottom of the cavity formed in the lower housing, one end of the spring being attached to the bottom wall of the housing by means of a plurality of screws 29, the free end of the spring pressing against the bottom wall of the case 30, of the lower stapling unit, in substantially the same manner as the upper stapling unit, above described.

The lower stapling unit, as indicated in Figs. 2, 3, 4 and 6 may be mounted in an outer case 30, of substantially rectangular cross-section, one end of the case having an opening 33, formed in the side walls 34 and 35 thereof, to receive the pivot pin 19, with one of the adjacent edges of the side walls rounded 36, to clear the bottom wall of the housing, when the case is canted into the position, shown in Fig. 1.

A pin or screw 37 may be inserted through one side wall of the housing, the pin engaging the bottom of a parallel-faced oval slot 38, cut through one side wall of the case, to limit the angular movement of the case about the pivot pin, in the open position, shown in Fig. 1. The slot '38 is made long enough to allow the case to move intothe cavity formed in the housing, to the stapling position, shown in Fig. 3. This construction 18 shown in greater .detail in Fig. 14, which shows a section through the .case

and the housing at the line of slot 33.

A row of staples 4-0, as indicated in Figs. 2- and 8,

. may be slidablysupported in the forward portion of the case, the prongs 42, of the staples, clearing the inner edge of the case side walls.

The rear portion of the bottom wall 43, of the case, may be cut out 44, the bottom of the side walls 34 and .35 being cut back, as indicated in Fig. 2, to provide an opening through which the staples, and the block, may be inserted into the closed forward portion of the case.

A block 45, madeiof wood, a plastic material, or other suitable material, may be slidably mounted in the case 39, the front end of the block pressing againstthe rear staples 44M, to pressthe row of staples against-the forward wall 46, of the case.

A long rod 47, of circular, or other suitable crosssection, may be located at approximately the center of the case, the intermediate section of the rod slidably-fitting into a longitudinal opening 48, formed in the center ofthe block45, to enable the blockto be slid along the rod, without contacting the walls of the case.

A loop 49 may be formed at the opposite end of the rod, an opening 50, formed at their centerof the loop fitting the pivot pin 19.

A coiled compression spring 51 may be mounted on the rod47, one end of the spring pressing against theblock 45, the opposite end pressing against the loop in-the rod, to force the block against the row of staples mounted in the case, regardless of the number of staples inthe case.

A loop may also be formed at the rear end of the spring 51, the openingin the loop, fitting over the pivot pin 19, to retain the spring in place, instead of the construction I shown in. Fig. 2.

A staple driver blade 52, formed of a thin strip material, may be mounted in the cavity of the lower housing, in a substantially vertical position, said element being in -.substantial alignment with the front staple 4%, when the staple is in the release position, shown inFig. 3.

The driver element maybe formed in an L-shape, the horizontal base section .54, being attached to the bottom wall of the housing by a plurality of rivets, screws or other suitable attaching means.

A narrow rectangular slot 55, may be cut out of the -;upper wall 56, of the case, adjacent the forward wall 46, the opening being wider than the thickness of the staple, Y toallow the forward staple till), to be pushed upward, by

the upper edge of the staple driver blade 52, to the positionshown in Fig. 3, the blade, passing through a similar rectangular slot 58, cut through the bottom wall 43, of the case, in substantial alignment with the upper slot, when the lower case is moved into the stapling position, shown in Fig. 3.

When the staple 49b is'moved upward, the prongs 42, straddle the side walls 61 and 62 of the narrow case 25, of the upper stapling unit 16, as indicated in Pig. 6, the inner edge of the staple prongs clearing side outer walls of the case, to allow the upper case to move from the stapling position shown in Fig. 3, to the openposition,

shown in Fig. 1, when the manual pressure on the housing is released.

The width of the cavity 14, in the upper case, maybe increased, by cutting additional grooves 63, into the side walls of the housing to clear the prongs of the lower staples :40, when they are pressed upward, into the stapling position, as indicated in Fig. 6.

The upper stapling unit 16 is constructed in substantially the same manner as that shown in Fig. 2, and hereportion of the case, in the same manner as the staples in the lowercase.

The rear edge of the side walls of the case may be those shown in Fig. 2 and previously. described.

'ofthe upper housing, as indicated in-Fig. 1.

A pin or screw 67, may be inserted through one wall of the housing, the pin engaging the top of a parallel-faced oval slot 68, cut through one side wall of the case, to limit the downward angular movement of the case, about the pivot pin, in the openposition, shown in Fig. 1. The slot 68 is made long enough to allow the case to move into the cavity formedin the housing to the stapling position, shown in Fig. 3.

The rear portion of the upper wall 69 of the case may be cut out, in the manner. indicated in Fig. 2, the side walls being cut back to provide an opening through which the staples and the block may be inserted into the closed forward portion ofthe case, in the same manner as those in the lower case.

A block '70 of substantially rectangular crosssection, similar to that shown in Fig. 2, although narrower, to clear the side walls of the case, may be slidably'mounted in the case, to press the staples againstthe forward wall 71, of the case.

The rod 47, and the coiled compression spring 51, pressingagainstthe block, are substantiallyrthe same as The staples maybe loaded in the case =30, by sliding the block 45, along'the rod 37, '[OWfildithG pivot pin'1l9, thereby compressing the spring 51. After. the block clears the rear edge of the bottom wall 43, of the case, a

-',10W of staples may beinsertedthrough the open section of the bottom wall, the release of the block.i5,-:pressing the staples forward into the closed section of the case, in the position shownin Fig. 2.

The upper casej25, ishownin Fig. 1, is constructed in substantially the same way, and may be loaded in substantially the same manner above described, except that the .staples are inserted through theopen section of'the upper wall 69,'of the case.

A staple driver element similar to that shown. in the lowerhousingmay be mounted adjacentthe inner edge of the forward wall 71,-of the upper case, the vertical staple driverblade 72, of the driver element,clearing the wall of the case, in the stapling position, shown in Fig. 3.

The horizontal base section 73, of the L-shaped staple driver. element, maybe-attached to the upperwall of the housingby rivets, screws, or other suitable attaching means.

A narrow rectangular slot 76 may be cut through the lower wall-76, of the case,.adjacent the. forward wall, to

clear the forward-staple 6517, when the staple is pressed -downward,-by the lower edge of the vertical-staple driver blade of the driver element, the vertical staple driver blade passing through a similar rectangular slot 77, cut through the upper wall of the case, in substantially alignment with the slot 75, when the'upper case is moved into the stapling position, shown in Fig. 3.

Fig. 9 shows a piece of fabric '80, folded over in two plies, 80a and 80b, after the fabric is'cut out in the form of a paper-pattern 81, or other suitable pattern. 'The paper patterntll, may beplaced on top of the fabric plies,

as indicated in Fig. 9, the fabricand pattern assembly being mounted above theupper wall of the lower case 30, in the position shown in Fig. 3, while the stapling units are in the open position, shown in Fig. 1.

The indicated location on the pattern, such as the positionof a button-hole,,or other similar location, may be moved into a position in alignment with theslot 55, in the lower case, the slot '75, in the upper case, or between the two slots, depending upon the accuracy of location, which is required.

After the fabric plies are located in the proper. position, the upper housing may be pressed downward by the op- :rator, the staple prongs entering the fabric in opposite lirections, with the cross-bar 82, of the wide staple 4t) abutting the lower edge of the fabric, and the cross-bar 83, of the narrow staple 65, abutting the upper edge of the pattern, as indicated in Fig. 11.

After the staples are in place, the fabric plies may be opened to the position, shown in Fig. 10, each staple, or row of staples, remaining in position in one layer of the fabric.

The wide staple 40 is attached to the right-hand section 800, of the fabric, to indicate the right-hand position of the right-hand pattern location, the narrow staple 65 being attached to the left-hand section'80b, of the fabric,

to indicate the position of the left-hand pattern location, as indicated in Fig. 10.

The prongs 42 and 64, of 70th staples, project upward through the fabric sections, as indicated in Fig. 10, thus allowing both staples to be manually removed, after the pattern locations are tacked, or permanently sewed.

The staples 40 and 65 may be made of wire of round, oval, or other suitable cross-section, in the substantially U-shaped forms, shown in Figs. 7 and 8, the wire being a metal wire, such as steel or brass, or the staples may be formed of a plastic filament, of substantially the same cross-section.

The open end of the prongs of both staples, may be pointed, 85 and 86, as indicated in Figs. 7 and 8, to facilitate entering the fabric, and removal therefrom, without injuring the fabric texture.

Both the wide and narrow staples 40 and 65, may be formed with plain prongs, as indicated in Fig. 7 or a series of serrations or corrugations 87, may be formed in the inner edge of the prongs 42 and 64, of both the narrow and wide staples, as indicated in Fig. 8, to grip the fabric, while the fabric layers are opened from the position, shown in Fig. 9, to that shown in Fig. 10.

The construction of the upper and lower housings 10 and 11 is shown in Figs. 4, 12, and 13.

The lower housing 11 may be of substantially rectangular contour, as indicated in Fig. 12, the sides 88 and 89, of the forward-portion of the base being extended outward, to provide a seat for the unit.

The cavity 15, of substantially rectangular contour, may be cut out of the forward section of the lower housing, as indicated in Fig. 12, the length of the cavity being somewhat greater than the length of the case 30, to allow the forward end of the case to be moved angularly from the open position, shown in Fig. 1, to the stapling position, shown in Fig. 3.

The upper housing may also be of substantially rectangular contour, as indicated in Fig. 13, the width of the rear portion 90, of the housing, being narrower than that of the lower housing, due to the narrower width of the cavity 14, to receive the case 25, of the upper stapling unit.

The sides of the upper end of the forward portion of the housing may be extended outward 91 and 92, as indicated in Fig. 13, to provide a wider striking area, to enable the operator to manually andrapidly move the upper housing into the stapling position, shown in Fig. 3.

The overall length of the housings would be considerably greater than that of the conventional type of stapling unit, to provide a long throat, into which relatively long fabric sections may be inserted, to mark the pattern locations hereinafter described.

The prongs of both staples may be open, after being driven through the fabric, as indicated in Fig. 11, or the prongs 64 of the narrow staple 65, may be bent over to close the staple, by providing a folding mechanism (not shown) below the slot 75, in the wall of the upper case.

The open end of the prongs may be pointed, as indicated in Figs. 7 and 8, or the tips may be rounded, depending upon the material of which the staples are made, and the texture of the fabric, through which the staples are driven.

The distance between the prongs of the wide staples would depend upon the prong-spacing of the narrow staples, the increment between the widths being great enough to allow the wide staples. to clear the side walls of the narrow upper case, as indicated in Fig. 6.

The wire used in the wide staples may be the same diameter as that of the narrow staples, or the wide staples may be made of a heavier diameter material, to offset the increased load on the longer cross-bar of the wide staples, to avoid bending the prongs.

While the narrow case and staples are shown mounted in the upper housing, in Fig. 1, the arrangement may be reversed, the narrow case being mounted in the lower housing, and the wide case in the upper housing, where an operating advantage can be gained by this arrangement.

It will be apparent to those skilled in the art that my present invention is not limited to the specific details described above and shown in the drawings, and that various further modifications are possible, in carrying out the features of the invention, without departing from the spirit and scope of the appended claims.
