Application June 10, 1946, Serial No. 675,516

1 5 Claims- This invention relates to apparatus for carrying articles under manufacture or assembly through various work stations, for example, parts of garments to the sewing, button attachment. and other work performing stations required for the completion of garments.

Heretofore in the assembly of garments, an operator must pick up parts on which she Works. arrange the parts in their required relation and then perform her allotted part of work on the garment. As an operator vfinishes her allo ed work, the garments are piled in a stack to await removal to the next operator. It is obvious tha much time is lost in picking up, sorting, and arranging the parts before an operator starts the actual work. Also, for many reasons, arments may accumulate at one operators station while the succeeding operator has finished her work supply. Such irregular movement of the work is not inducive to good and efficient work or in a uniform high standard of quality in the finished product. It is also difficultifo supervis rs to make inspections and to efficiently adjust the work to be carried on by each worker so as to maintain a smooth, steady flow of production. Other difficulties are that the parts are lik ly 1 be mixed, that is, parts cut from one fabric may be incorporated in a garment with parts out from another piece of fabric with the result that the finished garment may have different shades in parts thereof. In many cases the garments are soiled by dropping on the floor or the cloth becomes wrinkled and disarranged. Many of these diiliculties are also present .inthe straight line progressive piece systems now in "use by many manufacturers.

Therefore, the principal objects of the present invention are to overcome these dimculties by providing a garment conveyor wherewith partly finished garments are carried in succcssive order from one operator to the next; to provide for support of the garments by the conveyor while they are being worked. upon by the operators; to provide a conveyor which permits better observance of theflow .of production and inspection of the garments by the superiz'isors; and to provide for location of the operators at different elevations relatively to the tconyeyer so that the operatin machine is in position .to 3.13!) on the work while the work .is supported from the conveyer.

In accomplishing thcseand otherobjectsof the invention hereinafter pointed out, I have Jerovided improved structure, the preferred form .of which is illustrated in the accompanying d aw ings wherein:

Fig. 6 is a modifi d f rm o gar e t attachins me ns- R errin more in detail o e drawin s:

1 designates an apparatus for facilitating assembly of the parts of an article of manufacturn; for examp e, arm su h s w rk pants. indicated at 2 in the drawing. Work pants are u u lly assembled f o two n a s a front composed of a right front and a left front and a back composed of a right back and a left back which require certain operations thereon before the front back parts are united. For example, operations involved in c mp e g th backs are:

Serge the backs Dart the backs Set the left pocket Set the right pocket Finish the left pocket Finish the right pocket The operat ons carried upon the fronts of the garment are:

Serge the fronts Set and finish the watch pocket Set the front pockets Sew the 'buttonhole fly on left front Sew button fly on right front lithe operations car ie on n assem l n h backs and fronts are:

Sew the outseams Sew the inseams Sew on the band Sew on curtain Serge edges of backs from waist to crotch Face button fly Stitch band Tack and stitch down buttonholefly Buttonhole pants and pockets Seat seam fromtop of waist to bottom of fly Tape crotch Sew on buttons Tack belt loops Tack pockets .In view of the aboveoperations, the assembly of work pants may best involve the use of at least three conveyers of the type illustrated, one for carrying the backs to the stations at which the above mentioned operations of the backs are performed, one for use in connection with work on the fronts, and a finished line conveyer to facilitate completion of the assembly and finish of the garments. However, any number of conveyers may be used or the length of the conveyers may vary to accommodate the required operating stations in finishing any given type of workpiece.

In the illustrated instance a conveyer includes laterally spaced stands 4 and 5 each including telescoping sections 6 supported on a .base 1 and which are adapted to be adjusted for height upon loosening of a .clamping screw 8. 'If

necessary the stands may be braced by guys 8' to maintain stability thereof. Journalled on the upper ends of the stands are wheels 9 and iii having grooves H in the periphery thereof to accommodate an endless cable I2 such as a wire, rope, or the equivalent. The cable l2 preferably has a smooth exterior for mounting a plurality of rings or the equivalent l3 that are adapted to be frictionally engaged therewith or to slide relatively thereon. Flexibly attached to the rings l3 by connectors 14 are clips or pins i5 having substantially the shape of a clothespin as shown in Fig. 3. The connectors may be formed of stretchable material such as rubber or they may be coil springs M as shown pushes the garment away from the machine, the weight of the garment on the rings will cause the rings to be moved along the cable until the lower portion of the garment strikes a part 01 the next station so that it is in position for the operator of the next station to effect the work allotted to her after she has completed her work on the preceding garment and has been moved along to the next station.

The operator at the next station 36 may be required to work on a higher portion of the garment. Therefore, the machine will be carried on a stand 39 and the operators seat is supported on a platform 40 as best shown in Fig. 2.

Should one of the operators get behind with her work the garments which have been worked upon at a preceding station will be carried along by-the conveyer cable and will be stopped when they strike a part of that operators work station; for example, the table on which the machine is supported. The garments will continue to accumulate and be supported in position, but the operator may quickly grasp the first garment, move it into sewing position which when completed frees the garment for travel to the next station. Should an operator get too far j behind with her work the system may be planned in Fig. 6. The clip illustrated includes a pair ii of pivoted levers l6 and Il having gripping jaws l8 and IS on one of their ends to engage a workpiece therebetween. The other end of the levers serve as handle portions 26 and 2! by which the jaws may be moved apart against ,1.

for example, the wheel El. One of the wheels, for 1 example, wheel 9, carries a ring gear 29 meshing with-the pinion gear 36' that is fixed to the armature shaft 3| of a variable speed motor 32. The motor 32 is mounted in position on the post 5 by a bracket 33. The conveyer cable or strand i2 is thus adapted to move along a line of work stations 34, 35, 36 and 31 and returned on the opposite side of thewheels so as to travel along additional stations if desired. The stations 3 may be equipped with the machinesnecessary to perform the work to be accomplished on the workpieces carried by the conveyer such as a sewing machine, button attaching machine and the like. The machines are located at a' level with the work to be accomplished on the reso that another operator may be provided for that particular work on the garment. Then, the first operator may let every other garment go by so that the second operators work is in timed relation with the other operators.

In using the apparatus, the height of the cable from the floor may be adjusted to suit the length of the workpieces, and the stations arranged along the conveyer in desired sequence. The operator at the first station would take a part of a garment at a time from a pile and attach it by one of the clips to one of the rings oi the conveyer or she might first do her work and then clip the garment to a pair of adjacent clips being carried on the cable of the conveyer. When the work is completed, release of the garment permits the cable to pick up the garment and carry it to the next station where it stops in position to be engaged by the next operator. This operator may perform her allotted work and the garment passed on to the next operator and so on until it passes the last work station of the conveyer. The garment may then be removed and applied to a succeeding conveyer where it is carried along the various work stations assoand suspended from the link portions thereof,

the machine will beat a convenient level to permit the operator seated on the chair 38 to sew the waistband while the garment is supported from the cable of the conveyer.

As long as the operator is holdingonto the garment or the garment is in the machine the cable will merely slide through the rings. However, when-the operator finishes the work and ciated therewith.

During movement of the workpieces along the conveyer they are readily inspected by the supervisor. The garments are supported while being worked upon at their respective stations so that it is not necessary for the operator to support and position the garment preparatory to performing her allotted work. The garments are also supported 0E of the fioor so that they are v not apt to become soiled or disarranged.

It is obvious that the set up at the various stations might be changed from time to time due to change in style of the garment or the method of making the same. It is also obvious that various set-ups may be provided for different types of garments that may be manufactured. The fact that the apparatus described is adapted to be easily and quickly altered permits the emcient and economical machining of various garments to be produced by the machine.

From the foregoing it is obvious that the conveyer furnishes the operators with an orderly flow of work and that by use of the conveyer with which help may be given to every operator should they lag behind is also a feature of the invention and helps to maintain a steady flow of garments through the production lines. The individual movement of the respective workpieces also permits the increased visual control by the supervisors.

Use of the conveyers provides for more usable and clearer floor space as many of the tables, bins, baskets and the like ordinarily used in connection with manufacture of garments are eliminated.
