IMPROVEMENT IN HEMMER, MARKER, 650., FOR SEWING-MAGHINES.

6th: fitigeuule new to in tins: fitrtters intent me making part of tip same TO ALL WHOM IT MAY CONCERN Be it known that I, D. HEYER,'0f the city'of New Orleans, in thcparish of Oi-ieans, and State of Louisiana, have invented anew, useful, and improved Attachment for ScwingJ-Iachinos, for, the purpose of guiding, marking, or creasing, and preparing the cloth for hemming, tucking, cording, and quilting; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the some, reference being had to the annexed drawings, making-a part of this specification, in which-- Figure 1 is a perspective view of the machine, showing also the cloth prepared for hemming.

Figure 2 is a vertical section, taken at right angles to the line of sewing, showing also the cloth prepared for cording. Y

Figure 3 is a top view, showing also the operation of tucking and creasing.

Figure 4 is a perspective view of the machine, attached to the stationary arm of a sewing-machine, showing the manner-of using it as a quilting-guide.

Figures 5 and 6 are plans of pieces of metal, of which the main portions of the machine are made.

Figures 7 and 8 are vertical sections, showing the metal strips bent into shape.

Similar letters indicate corresponding parts in thcscveral figures.

This invention consists in a novel and very simple arrangement of the various attachments to sewingmachines, so that they may be all combined in oncmachine. V

Itelso consists in forming the hamstring-device with a concentricgroeve, and a roller running in an oblique slot, for keeping the edge of the cloth to he hemmed always in the groove.

It also consists in forming the quilting-guide by a projecting edge, making a part of the same machine.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction 4 and operation.

A, fig. 5, represents along, narrow flat piece or metal plate, having a portion cut out at b, and being perforated with oblique slots at a a, and having a middle longitudinal slot, c, half of which is much wider than the other part. This metal plate is bent, at the dotted lines, into the form shown at fig. 7, the-part rl coming before. 0, which forms a straight-edge or gauge. The portion f forms a spring, which keeps the horizontal part,g, down on the cloth. The plate is also provided with rollers, r r, having either grooved or flat faces running in the oblique slots a a, and is also provided with a screw at k, fitted with a nut, Z, as shown in figsrl, 2, 3, 4. A second fiatometall plate is shown at B, 6, having a portion cutout at m, and being perforated at n ando withtwo rectangular slots, one being placed straight and the other obliquely. This piece is bent, at the dotted lines, into the form shown at fig. 8, the portion p being bent into a concentric form. It is also provided with a groovedrollcr, running in the slot at, and with another, either grooved or flat, running in the slot 0, and provided-with an elastic axis, q, to allow it to rise or fall according to the thickness of the-,cloth operated upon. This is shown in figs. 1, 2, 3, 4. The piece}? is attached to the part A by'inserting it at b, and clamping it in any position by the nut Z. The machine is now complete.

I do not limit myself to constructing the machine of sheet metal, and bending it into shape, for it may be constructed' by casting, or other means, of any suitablc-material, and the concentric groove in B may be cut, out of the solid material; nor do I limit myself to making the concentric groove circular, for it may he fiat or angular.

The manner of using my invention for the different operations of which it is capable is as follows The machine is secured to the plate of a. sewing-machine, at right angles to the line of sewing, by a screw passing through the slot 0, and into a, screw-hole in the plate. To use the machine as aguidc for sowing, it is, merely necessary to insert the clothmnder the horizontal piece g, and pass it to the feeding-mechanism of the machine. As the cloth is drawn along, the oblique-placed rollers, r 1', revolve by the friction of the cloth and force it fllWflXSjJP to'thc gauge, as shown in fig. 3. If desired, the part B can be turned out of the way, or entirely rcmm'pd. To Mick and crease the work, the cloth is placed as bct'ore, and the piece 13 is clamped to the portion'A by the nut Z, the end containing the grooved roller 8 projecting over the cloth at such a distance that the grooved roller will mark the place of the next tuck. When the cloth is moved along, the grooved roller will mark a. narrow'double crease, and the cloth will rise slightly between the two creases, so that it can be readily bent by the fingers end folded for the next tuck. The operation is shown in fig. 3. To cord, the machine is arranged in thesaine manner, but the grooved roller s is moved close up to the guide; as shown in fig. 2, and thepiece of cloth containing the cord is placed under the plate, the portion covering the cord passed under the groove in the wheel 8, and drawn through, as before. To hem, the ninchine'is arranged as shown in fig. 1, the concentric portion, 1.1, being projected sufiieiently beyond the gauge for the width of thehem required. The cloth is placed doubled under the horizontal piece and the edge is then laid in the concentric groove of n and drawn through, as before. The obliquely-placed roller t, revolving by the friction of the cloth, always keeps it close up to the end of the groove. To quilt, the machine is attached, by a screw, to the stationary arm of c. seiriri'g-niachinbQas shown in fig. 4, the portion B being clamped to A obliquely, placed over a. line of stitching at the distance from the needle required, and the cloth, guided by this edge.

What I claim its myinveiitio'n; mid desire to secure by Letters Patent, is-

1. The heinmerp, formed with a concentric groove, and provided with a roller, p ing the ,work in the groove, and constructed substantially as specified.

2. The combination, in n single machine, of a sewing-guide, hemmingdeviee,tucking and creasing-device, cording-device, and quilting-guide, constructed and operating substantially as specified.
