5 Sheets-Sheet 5 IN VEN TOR. 44,419 WN/QJAXB Y United States Patent 0 MACHINES FOR MAKING SHOULDER PADS Marvin R. Saxby, Tottenville, Enterprise Corporation, tion of New York N. Y., assignor to Machine New York, N. L, a corpora- This invention relates to an apparatus or machine for making garment parts, and more particularly shoulder pads of the triangulated form presently employed in womens dresses, coats and other garments.

These pads usually consist of a soft interior padding or lining covered by an outer textile fabric. this kind are in the form of a square section of both materials in superposed relation, folded diagonally and stitched along two edges of the pad to form a triangulated pad with both of its exposed faces covered by the outer fabric or covering.

It is an object of the invention to provide an apparatus for producing pads of this character, and which pads will be rapidly and uniformly produced at a minimum of manufacturing cost.

It is another object of the invention to produce an apparatus which will feed the pad material; which will sever the material into the required lengths or squares; fold the severed sections diagonally and hold the resultant folded, triangular sections While two of the edges thereof are stitched to produce the finished triangular pad, and to provide means for extracting the finished pad from its holding means.

With these and other objects to be hereinafter set forth in view, I have devised the arrangement of parts to be described and more particularly pointed out in the claims appended hereto.

In the accompanying drawings, wherein an illustrative embodiment of the invention is disclosed, Fig. l is a top plan view of a machine constructed in accordance with the invention but with certain portions of the machine omitted to more clearly show features of the invention.

The machine forming the subject matter of the present invention, is particularly adapted for the manufacture of shoulder pads of the type used in dresses, coats and other garments intended for feminine wear. Such a pad is disclosed in Fig. 2 wherein it will be observed that the same is of triangular form and consists of an outer covering of a relatively closely-woven textile material 1 enclosing a lining or padding 2 of cotton or other suitable soft, compressible material. These pads are usually made by folding a square section of the padding and underlying cover material on a diagonal line and then stitching together the two meeting edges of the doubledover square by the stitching extending along said edges and indicated at 3 and 4.

Pads of I.

2,714,350 Patented Aug. 2, 1955 ice In the machine of the present invention, the padding and covering fabric therefor are intermittently fed together from a source of supply, such as webs from supply rolls, to a point where squares of the padding and underlying fabric are successively cut off. Each square is suctionally held upon an angularly-slotted supporting plate until a descending blade strikes the square of padding-and-covering, thus folding it diagonally upon itself and forcing the doubled-over square down through the slot in the supporting plate. A clamp is, at that time, positioned below the slot in the supporting plate and as the doubled-over square is forced down through the slot, it enters into the open upper end or mouth of the clamp and is received and held between the jaws of the clamp. The blade then begins to rise, and tendency of the pad then located between the jaws of the clamp to follow the rising blade, is prevented by a retaining means in the form of a member having prongs which enter through openings in the clamp and penetrate the pad and hold it between the jaws of the clamp until the rising blade clears the upper limits of the clamp. The clamp, which is one of several clamps carried on a conveyor, and is moved through a rectilinear path, is then pivoted downwardly to a horizontal position and is moved by the carrier to a sewing machine which applies the stitching shown at 3. The conveyor then carries the clamp with the partially stitched pad between its jaws to a second sewing machine which applies the row of stitching indicated at 4, and the sewing of the pad is then completed. The clamp, now carrying the sewed pad, is moved to a. final position, where a rotating extractor grips an exposed part of the pad and draws it out of the jaws of the clamp and carries it away from the clamp to a point of discard, where the finished pad is released by the fingers and dropped into a suitable collection receptacle.

The invention includes a number of other features present in the machine, and the construction and operation of the same will be readily apparent as this description progresses.

By reference to Fig. 3, it will be noted that the supply of padding material 2 is carried by a supply roll 5 suitably supported at one end of the machine. The supply of relatively closely-woven, thin covering material 1 is drawn from the roll 6, and the two webs from the rolls are drawn therefrom toward the left over the table 7, with the covering material 1 disposed underneath the padding.

The padding and the covering material are moved toward the left in Figs. 1 and 3, by means of a reciprocating carriage 8, including a plate 9, carrying a plurality of needles or prongs til which penetrate the padding and covering upon the descent of the pronged plate, and thus pick up the material from the surface of the table 7. The carriage plate 9 is supported from the cross bars 11 by bars 121:, the cross bars 11 riding on vertically-movable rails 12 carrying rollers 13 for engagement with the in clined faces of earns 14. The earns 14 are mounted on a slide 15' suitably actuated by an air cylinder 90 or other means by which said slide will be reciprocated at the proper time. The feed carriage 8 is reciprocated by the air cylinder 16 in which a double-acting piston is contained, the same being moved in opposite directions by the air flow through the pipes or tubes indicated at 17 and 18 respectively. The piston rod 19, extending from the piston in the cylinder 16, terminates in a clevis 20 pivotally attached to a lug 21 extending upwardly from one of the cross bars 11 of the feed carriage. Table 7 is grooved as at 91 to provide clearance for prongs Iii.

The arrangement just described is such that when the piston in the cylinder 16 is moved toward the right, as viewed in Figs. 1 and 3, the carriage 8 will be drawn in that direction While held elevated by the earns 14.

At the end of its travel toward the right, the carriage Will be caused to descend by movement of the cam slide 15 toward the right, and the descent of the carriage will cause its prongs to penetrate the padding 2 and covering material then underlying the same upon the surface of the table 7. The carriage 8 is next moved to the left, and it will move the padding and covering material then impaled on its prongs along the surface of the table. Adjacent to the left end of the table 7 and adjacent to the grooves 91 is provided suction openings 23 through which suction is exerted to hold the end portion of the material on the table during elevation and retracting movements of the carriage 8. The carriage is next elevated by movement of the slide and it becomes free from the material and retracts toward the right, while the padding and covering material is suctionally held on the table 7.

On the next feeding movement of the carriage 8 by the means just described, the covering material and padding is urged forwardly beyond he table 7 and over the face of a substantially square suction plate or block 24, shown in plan view in Fig. 6. The suction plate 24 is provided with a fiat upper face 25 and a hollow interior. The suction holes 26 emerge at the upper face of the plate, and a vacuum is exerted through the plate by means of a pump or other source, operative through the piping 27 connected to the hollow interior of the plate 24. Extending diagonally across the suction plate 24 is a slot 28 and a square of the padding and underlying fabric covering is thrust downwardly through this slot in a manner to be presently explained. The square of the padding and covering therefor that is cut from the webs is severed by means of a pivoted knife blade or shearing member 29 which is pivoted at 30 and co-operates with a fixed shearing blade 31 to sever successive squares of material of predetermined size from the webs. The blade is pivotally moved, at the required times, by means of an air cylinder indicated at 32.

Located above the suction plate 24 is the folder blade indicated at 33, and the same is secured by the bracket 34 to a plunger 35 which is caused to vertically reciprocate by means of an air cylinder or other suitable actuating mechanism. The lower end of the blade is notched as indicated at 36 to clear retaining prongs on an element to be shortly described. The lower end of the blade 33 is provided with prongs 37 which, upon the descent of the blade, penetrate the square of fabric then resting on top of the suction plate 24 and prevent the square from becoming askew while it is being doubled upon itself and is being forced downwardly through the slot 28 in the plate 24.

When the blade 33 descends through the slot 28, forcing the doubled square of material down through said slot, a clamp 38 of the type shown in Fig. 5 is positioned directly below the slot 28 in an upstanding position with its mouth or open end in position to receive the folded pad. The clamp consists of a pair of triangular plates or jaws 39 held in suitably spaced relation by a spring hinge 40. The clamp is also capable of pivotal movement on a pivot 41 to enable it to assume either a vertical position as shown in Fig. 5, or else assume a flat or horizontal position as indicated at A and B in Fig. 1. It will also be noted that the jaws 39 of the clamp are apertured, as shown at 42, to permit of the passage of a pair of prongs 43 provided on a swinging arm 44. Said arm 44 is pivoted at 45 on a bracket 46 which has an arm 47 supporting a solenoid 48. The core 49 of the solenoid 48 is pivotally connected to the

pivoted links

50 and 51, and the link 51 is pivoted at 42 to the end of the arm 44. This arrangement is such that when the solenoid is energized, the core will be retracted and the arm 44 will be swung in a manner indicated by the dotted lines in Fig. 4. This will cause the prongs 43 to enter through the apertures 42 in the clamp and penetrate the doubled-over square material now in triangular form then held be tween the jaws of the clamp. The prongs 43, thus entering the pad then held by the clamp will hold the pad until the blade 33 is elevated out of the clamp, so that any tendency on the part of the folded pad to rise out of the clamp when the blade 33 is elevated, will be prevented by the prongs 43.

In the arrangement shown, four clamps at equally spaced positions, are moved through a rectilinear path from the loading station directly below the slot 28, and indicated at C, to the sewing stations indicated at A and B respectively and thence to the extraction station indicated at D. The clamps are moved by a chain conveyor, a portion of which is shown at 55, and which is of known construction and therefore will not be herein dercribed in detail. It is sufficient to state that the conveying means moves the several clamps to the several stations where the sewing occurs and the sewed pads are successively moved to the extraction station where they halt and are removed by an extractor to be presently described.

After a folded square of the padding and covering therefor has been inserted in a clamp then located at the station C directly below the slot 28, and the blade 33 has been eievated and the prongs 43 withdrawn from the apertures 42, the clamp at station C is then folded down to horizontal position. This is done by means of a pushrod 56 having a rounded knob or end 57 which, upon forward movement of the push-rod, impinges against the then vertical clamp and folds the same downwardly upon its hinge 41. The push-rod is connected to the piston of an air cylinder, and said piston is double-acting and is moved in two directions by the air fiow exerted through the conduits indicated respectively at 59 and 60. The folded-down clamp, now in its horizontal position is moved under a frame 61 which holds it down in a horizontal position, while the push-rod retracts to the position shown in Fig. 1.

The folded square of padding and covering material that is held in each clamp has two of its edges, namely, those in which the stitching 3 and 4 is placed, protruding beyond the edges of the jaws of the clamp so that the stitching can be made along those edges of the pad. As the folded-down clamp is moved from the station C to the station A the edge which receives the stitching 3 is guided between guide rollers (not shown) preparatory to reaching a sewing machine 63 which is preferably of the merrow or zig-zag type, and which sews the stitching 3 along one edge of the pad. When the pad reaches the point A, the stitching 3 has been applied, and now the pad is moved toward the station E and past a second sewing machine indicated at 64. On its way to the sewing machine 64, the edge of the pad that is to receive the stitching 4, is flattened under rollers 65 suitably rotated by belt drive 66 to press down the edge of the pad. The sewing machine 64 produces the line of stitching shown at 4 and the work on the pad is then completed. The two sewing machines are driven at similar speeds by means of the connecting driving means extending between them and consisting of the bevel gear 67 in mesh with a gear 68 on the shaft 69 carrying a gear 70 that meshes with a gear 71 on shaft 72 which carries the bevel gear 73 in mesh with the gear 74 on the drive shaft 75 of sewing machine 64.

Means is provided for cutting the threads at the conclusion of each sewing operation, such means not being shown herein but being the subject matter of my copending application Serial No. 398,519, filed December 16, 1953. It is sufficient to state that when the pad reaches station B, the same is complete and is in the form shown in Fig. 2 and is ready for extraction from the machine.

The extraction or delivery point is shown at D and at this point the clamp holding the finished pad has risen to a vertical position with the sewed portion of the pad protruding slightly out of its jaws. The extractor includes a vertical rotated shaft 76 carrying a radially-extending arm 77 at the end of which is a pair of

fingers

78 and 79, said fingers being adapted to be either brought together into gripping position when engaged in holding the pad, or else separated to cause them to release the pad at the required time, by means of the stationary cam around which the arm 77 rotates.

From the foregoing, the operation of the described machine will be readily understood. By means of the feed carriage 8, the padding and covering therefor are moved along toward the cutting means 29, 31 where the material is cut off into squares of predetermined size and said squares are successively delivered to the suction plate. The descent of the blade 33 doubles each square upon itself, and forces it between the jaws of the waiting clamp. The retainer 44 has its prongs forced into the pad and holds it in the clamp while the blade 33 ascends. Pushrod 56 folds the clamp down to a horizontal position and the clamp, while in such position is moved to the sewing machine 63 where the stitching indicated at 3 occurs. The clamp then carries the pad to the sewing machine 64 where the stitching 4 occurs. Now the finished pad is moved to the delivery or extraction station D. There the arm 77 swings around to cause its

finger

78 and 79 to locate the projecting edge of the pad between them. The cam 30 closes the. fingers on the pad, and as the swing of the arm 77 continues in a counter-clockwise direction as viewed in Fig. 1, the pad then held between the

fingers

78 and 79 will be drawn out of the clamp and carried by the extractor to a point beyond the edge of the table 81. At this time, cam 86 will act to separate the

fingers

78 and 79, allowing the finished pad to drop out into a waiting receptacle.
