UNITED STATES PATENT OFFICE FABRIC HOLDING EQUIPMENT FOR EMBROIDERY MACHINES Joseph C. Gilardone, Fleetwood, Pa.

Application March 22,

Claims.

This invention relates to the fabric holding yequipment of embroidery machines, and more particularly to such equipment for hosiery embroidering machines of the general type dis- -5 closed in my Patent No. 1,482,680, issued February 5, 1924.

One object of my invention is to provide a novel fabric, or hosiery, holding device for embroidery machines.

Another object is to provide a novel fabric, or hosiery, holding frame'unit comprising a plurality of fabric holding devices, and a support therefor arranged to be mounted in a plurality of positions in the machine.

Still another object is to provide novel means in embroidery machines for more effectively and efficiently holding the fabric portions to be embroidered in position for cooperation with the embroidery stitching means, than heretofore possible.

A further object is to increase the production speed and efficiency'of embroidery machines by the provision of novel means therefor whereby the fabrics to be embroidered cany be more quickly and easily manipulated than heretofore, and wherebymore uniform results are obtained.

Another object is to provide novel hosiery holding equipment for embroidery machines which can be cheaply manufactured, which is 30 capable of self-adjustment so as to accommodate, with equal effectiveness, hosiery of different size, and which provides other advantages over equipment heretofore available for this purpose.

With these and other objects in vie'vv,v which will become apparent from the followingy detailed description of the illustrative embodiments rof the invention shown in the accompanyingdrawings, my invention comprises the novel elements, features of construction and arrangement of parts in cooperative relationship, as hereinafter more particularly pointed out in the claims.

Fig. 9 is an end elevational View with a stocking portion in position, partly in section; and

Fig. 10 is a view similar to that of Fig. 9, and shows certain parts in another position.

For illustrative purposes; a practical form of my invention will be hereinafter described as applicable to well known hosiery embroidering machines. In such machines, a multiplicity of individual hosiery holding frames or devices, are simultaneously moved as a unit by patterning means with respect to cooperatively associated embroidery stitching mechanism which functions to produce similar clocks, or other ornamentations, in each ofthe stockingson Vthe frames. The stocking holding frames, or devices, are generally of a rectangular shape and are open at the front, rear and bottom so that Y they may be positioned vertically over the individual shuttle arrangements of the embroidering mechanism. When a stocking is properly mounted on one of these frames, the portion of the stocking fabric at the front open side of the frame is positioned between the shuttle arrangement and the needle.

When the machine is in operation, all the stocking holding frames are moved in accordance with pattern controlled means, relative to the stitching mechanism which is mounted in fixed position, and in this manner a design is embroidered in the stocking fabric.

After a design has been embroidered in one side of the stocking, each frame is reversed so that the fabric extending over the rear `open end of the frame comes between its respective shuttle arrangement and needle, and the embroidering operation is repeated.

My invention is concerned with the stocking holding means of the type referred to.

The well known parts of an embroidery machine have been omitted in the drawings because their illustration is unnecessary to a com* plete understanding of the construction, function and operation of my invention by anyone skilled in the art. However, for additional information concerning corelated and associated parts, reference may be had to my above mentioned patent, and my Patent No. 2,094,699, issued October 5, 1937.

Referring now to Figs. 1 to rI inclusive of the drawings, II designates my novel hosiery holding frame members or devices, I2 elongated supports on each of which a plurality of the members II are detachably mounted, I3 brackets which are positioned intermediate the ends of adjacent supports I2 and on which the latter are seated, I4 a bar extending thev full length of the machine and to which brackets I3 are secured, I5 another bar extending the full length of the machine against which the upper parts of members I I are held to steady the same, and I6 another bar extending the full length of the machine to which vertically extending bracket supporting rods Il are secured.

The members II comprise an upper frame element I8 which is formed of a dat strip of resilent material, such as spring metal, Celluloid or the like, and a rigid base or frame I9, so formed as to provide an opening centrally and at the bottom of the device II to permit the latter to be positioned over a shuttle arrangement, for the purpose mentioned. The base I9, is provided with horizontally extending flanges 2i at the front and rear thereof, along which are secured a plurality of fabric impaling points 22. A foot plate extension 23 projects beyond the base on both sides thereof and these are notched as at 24 to accommodate the Shanks of bolts 25 `which form part of the means for detachably securing the devices II tothe elongated supports I2.

The outside surface of the frame member I3 is polished, or otherwise made smooth, in order that a stocking, indicated'at 26, may be drawn on and pulled from the same without injury to the fabric. To facilitate rthe mounting and dismounting of a stocking on the member II, the upper portion of the frame I8 is rounded or made 'arcuate' in configuration. Four horizontally aligned notches 2'I are also formed in the edges of the frame I8 to provide a seat for a rubber band 28, or other exible fastening means, placed over the stocking 26 at this point, for the purpose of maintaining the stocking fabric, between the rubber band 28 and the impaling points 22, in position and under desired tension.

Each of the elongated supports I2 is preferably made as an integral casting, but it can also be formed of separate parts; and comprises side rails 29 which are joined by reinforcing cross plates or members 3| which are centrally provided with bolt receiving apertures to accommodate the bolts 25. The end members 3io, and SIb are provided at their bottom with grooves 32. These grooves are somewhat wider than lugs 30 on brackets I3 so that the grooves and lugs eifect a loose seating arrangement for the supports I2 that permits of limited lateral tilting movement of the latter. This will become clear by reference to Fig. 7 which sho-ws the upper part `of a frame element II tilted against bar I5 and yieldably held in this position by a tensioned rubber band 33 which is anchored on bar I5, extends between two adjacent devices II, and is connected at the front of the latter with a retaining elementY 3d which rests against the at hosiery fabric holding rubber band 28. The retaining element 32 may be of wood, or other light material and extends partly across two ofthe devices I I so as to simultaneously function with rubber band 33 to,`

draw or urge both of said devices toward and against bar I5. It Will be noted that the element 34 is actually in contact with the rubber bands 28 on the devices II, which bands in turn suitably compress and hold the fabric of stockings 26 in the edge notches 2l. In this manner a convenient arrangement is provided whereby the stockings 26 are clamped against the upper parts of devices I I and the latter yieldingly held against the bar i5 without danger of injury to the stocking fabric. As an additional precaution for preventing injury to the fabric a continuous rubber strip, or separate rubber pads 35 are secured to the bar I5 to act as cushion contact means for the fabric when the members II are pulled and held against the bar I5 by the rubber bands 33, acting through elements 34.

It will be noted that six of the devices II can be conveniently mounted on one elongated support I2 by placing them in aligned arrangement between and alo-ng the rails 29 in such manner that the extensions 23 which project from the base of each device II, meet with those of an adjacent device li at the center of cross plates 3l on supports I2. By referring to Fig. l, it will be apparent that when the devices I I are so arranged, the bolts on support I2 will be sidewise straddled by the notches 2li of extensions 23 onV adjacent devices. Thumb nuts 36 are provided on the threaded portions of bolts 23 to simultaneously clamp tvvoy adjacent extensions 23 onto the cross plates 3I and thereby detachably secure the devices II to the support I2.

I have shown a support I2 with six devices II mounted thereon as comprising a hosiery mounting unit, but, of course, the number of devices II can be varied.v Such a unit can be conveniently handled and mounted, rst in one position, then removed by lifting the two retaining elements 34 over the tops of the last two-'devices Hat each end of the unit, then lifting the unit from its end seats on brackets I3, reversing it and again seating it on the lugs of brackets I3. By tilting the entire unit rearwardly and again placing elements 34 over the rubber bands 33 of the two devices II at both ends of the unit a quick and easy reversal of six of the devices is effected. Thus, instead of reversing the devices II, one by one, as heretofore, my invention makes it possible to reverse a multiplicity simultaneously.

Attachment, or removal of the devices II from a support I2 is quickly and easily effected by means of the thumb nuts 35 whch,`except at the ends of the units, in each instance secure the extension members 23 of adjacent devices II in place.

Referring now to Figs. 8 to 10 inclusive of the drawings, it will be noted that a modified hosiery fabric holding, or attaching means, is here illustrated as arranged on the base frame or portion of the hosiery mounting devices, designated by the numeral ila. The devices IIa correspond in all respects with the devices Ii, previously described, except for the fabric attaching means at the base. In view of this, the parts of device IIa which correspond With similar partsy of devices I i have similar reference characters applied thereto in these figures with the exponent a added in each instance.

The modified fabric attaching means comprises four angle pieces 31, one pair at the front and the other at the rear of the base, the two angles -of each pair being arranged in opposition to one another so as to form a channel-shaped fabric holder with an opening, or slot 39, extending the length of fai-18,614

.a -Itis to `be understood that my invention inves' cludes all the novel elements and parts which result in ladvantageous features in fabric holding means in embroidery machines over the prior .am t,

It is also noted that due to the shape and 'construction of H, there is provided a Ahosiery holding means which is self-adjusting to various sizes of hosiery because ofthe resiliency and limited yieldability of these frames. This feature is indicated in Fig.

2, wherein the devices port; and a plurality II having hosiery 26 mounted thereon, are contracted, more or less, intermediate the ends of frame member I8 by the hosiery. The effect is somewhat exaggerated for illustrative purposes.

As previously stated, in hosiery embroidering machines of the type to which my invention may be applied, all the hosiery to be embroidered is simultaneously moved in accordance with patterning means, relative to the embroidery stitching mechanism. Therefore, when my novel fabric, or hosiery holding means, is properly positioned in the machine, and the individual shuttle units are located within the devices II in readiness for cooperation with their respective stitching needles, which simultaneously coact with the shuttle units, all the devices II are moved in accordance with the usual and well known patterning means of the machine. The parts 'which are moved in unison by this patterning means include the devices II, supports I2, bars I 4, I5, I6, rods I'I and all associatedelements. The movement is mainly a vertical one, but limited sidewise motion is also effected.

Of course, my improvements in fabric, or hosiery holding equipment, as specifically shown and described in connection with hosiery embroidery machines, can be changed and modified in various ways without departing from the invention herein disclosed and hereinafter claimed.
