ROBERT RHYON, OF MONTREALQQUEBEC, CANADA.

SEWING-MACHINE ATTACHMENT.

y Application filed March 23, 1923. Serial No. 627,168.

To all 'LU/wm it may concern Be it known that I, ROBERT RHYON, a citi- Zen of the United States, and resident of the city of Montreal, in the Province of Quebec and Dominion of Canada, have invented certain new and useful Improvements in Sewing-Machine Attachments, of which the following is a full, clear, and exact description.

This invention relates to new and useful improvements in attachments for sewing` machines, and the object of the invention is to provide an attachment which will automatically guide, feed andprepa-r'e for stitching together three pieces of fabric where one piece is to have a hem turned over another intermediate piece, such as a stiften y ing member and a third piece isto be stitched Ato the other members to form a lining or facing therefor. The attachment is particularly adapted for use in making the waistband of trousers or` the like.

In my invention I provide a sewing base plate for the machine with slotscut thereinV and placed in such a manner that thefabrics to be stitched together are led in the proper position for stitching, adjustable guides being provided to accommodate the various widths of fabrics to be used,'said guides being provided with top and bottom guards for this purposeY attached to the underside of the sewing base plate and is adapted to leadthe hemming cotton and double same over the stilfening fabric before they are stitched together.

The fabrics are wound on ree-ls which are rotatably mounted in brackets attached to y the main bed of the machine.

In the drawings: e e Figure 1 is a perspective view of the attachment litted to a sewing machine.

Figure 2 is a perspective View of the base plate. i

Figure 3 isa perspective view of the heniming member. y e

Figures 4 and 5 are views of the guides. Figure 6 illustrates the finished work. y Referring more particularly to the drawings, 11 designates the main bed of a sewing machinel upon which is mounted the L bracket 12 supporting the head 13 of the sewing machine, in which the needle bar 14 is slidably mounted `and operated in the well known manner. A sewing base plate 15 s mounted on pillars or distance pieces The binding member is 16 through which, and the base plate, screws 17 are fitted into the bed plate. The pillars 161 may be loosely mounted on the screw 17a for reasons herina-fter described. Mounted on the bracket 13 which is attached to the bed plate is the reel '19 of stiening fabric or canvas, the sides of the reel being adjustable to any desired width of canvas. Also attached to the bed plate .by the bar support 2O are the reels of

cotton fabric

21 and 22. The cot-ton fabric reels are rotatably mounted on the spindle A3 which lits into open ended slots 24 cut in the bar supports 20, the said slots being` sloped so that any pull on the reels tends to hold the spindle 23 in position in the slots in the supports. The cotton on the reel 22 is used as the binding material and is led around the rotatably mounted pillar 16a to a binding or doubling member 25 which is secured by a. bent bar 26 to the underside of the sewing base plate. The doubling or binding. member consists of a flat hollow piece of metal curved at one end 27 to receive the cotton 22 and it is doubled over about its longitudinal centre at its other end, so that the cotton will be doubled over when it is drawn through the said end. A slot 29 is cut in the base for the canvas or stiffening meinber 19 and is guided therethrough by the guard 30 which is provided with guiding

pieces

31 and 32. the piece 32 being placed below the base plate and the piece 31 being positioned above the base plate, both pieces being oined together by the narrow neck 33 which is made to turn easily in the slot for dismantling.` The binding member is so positioned that the canvas 19 passes between the folded edges 22a of cotton before going through the slot` 29. The cotton 21a on the reel 21 passes over the top of the base plate and is taken through the long narrow apertures 34 towards the needle 35. Guides similar` to that shown in Figure 4 may be used or the pieces 31a may be shortened to y prevent overlapping of the slots cut in the binding cotton. The fabrics are then fed through the machine in the usual manner and stitched together by the threads 38. A. hole 39 may be drilled in the base plate to accommodate the rack feed cover plate 4:0 or the slots 41 may .bei cut directly in the plate for the feeding mechanism and needle. In the drawing I have shown an attachment for stitching' three pieces of fabric together but by slight modifications and cutting more slots in the machine base plate a greater number of fabrics may be automatically stitched together inthe one operation. A startingy slot l2 vmay be cut in thebinding member to assist in guiding the binding cotton through the guide by hand.

The operation of the device is as follows: The reels are, wound with fabrics of a. dcsired width cut on thebias and are mounted in the brackets on the bedplate of the machine. The canvas or stiffening member is taken.' under the. base plate and through the slot, nearest the doubled end of the doubling member. The binding Vcotton is taken from thereel around the rotatable pillar through the flat end of the doubling member and then through the doubled end folding itself over the edge of the canvas before passing through the same slot as the canvas to the upper surface of thefbase plate. The facing cotton. is first taken over the top of the base .plate .through one slot to the under side of the said. plate yand.t.l1en through another slotback onto theupper surface of the plate and so guided. that one edge of the cotton coincides with one vof the edgesof the bindingcotton. The reason for passing the cottonthrough the-double slots. is that theyprovide a tension for the feeding of said cotton. The three pieces are then fed towards the needlein t-he usual manner and stitched together as shown in Figure 6 of the drawings.

This attachment is a great saving as re- ,gardsetime .expendedfor operating and also material used, the operation being entirely automatic; 1n its action .andonly .needs the attention. ofv an. operatorvfhen setting-up.

needs no trimming when taken from the machine. The guards are provided with guiding pieces,.one above and-fone .belowthe .base plate, to keep the material in perfect align ment whenpassing. through the machine.V

.They are also placed as near the needle bar as possible .and whenv the guardiextends over the bound stiifening member4 as shown-in Figure l, arecessis cut as shown in Figure 4 and designated 4t3,to allow the guard to be .bolted to the. base plate and yet allow free movement of the stiftening member under it.

This attachment may be used for double curtains for trousers.

I-Iaving thus described my invention, what I cla-im is l. An attachment for sewing machines comprising a vbase plate adapted to be mounted above the bed plate of la sewing machine, a plurality of reels for fabric rotatably mounted on brackets attached to the bed plate, a doubling member secured to the underside of the base plate and adapted to receive fabric from one of the reels, said base having a slot for the passage of a stili'ening fabric which is bound by the doubled fabric before passing through the slot, and long narrow apertures in the base plate for thc remaining fabics and means to guide and posit-ion all the fabrics through the slots.

2. An attachment for sewing machines comprising a base plate mounted above the bed plate of a sewingmachinea pluralit)v of reels for fabric rotatably mounted on brackets attached to the bed plate, said bed plate having a slot adapted forthepassing of one of the fabrics, a doubling'member. means lto secure the doubling? member to th(` underside of the base plate, andso positioned that one edge of thestiifening member is bound vby the doubled fabric before passing` through: the slot, a guard with top and bottom guides for positioning said bound stif ening member, said base plate having other slots for the remaining fabrics. guardsrwith top and bottom guides situated in said slots to hold the fabrics in positionand adjusting means for altering-v the positions of the guards to suit varying widths of fabric.

3. Ina sewing machine attachment, a base plate,=pillars for supporting said base plate, a hollow doubling member situated under said base plate adapted to receive fabric led around one of said pillars. and n, slot cut in the base plate situated near the doubled end of thedoubling member.

4. In a device of the characteifvdescribed. a base, means to support said base. ya. doubling", member attached-to andv situated on the underside of said--base,said base'having The material 1s c utv to the exact width and-- gether by a narrow neck, to allow the guard to be fitted in said aperturealthetop guides being above the base and the bottom-guides being Abelow the base, and means for adjusting said guards.-

In witness whereof, I have hereunto set my hand,- f
