HEMMER FOR SEWING-MACHINES.

T at whom it may concern.-

Be it known that I. JOHN W. EsHELMAN, a

citizen of the United States, residing at Pas saic, in the county of Passaic and State ofNew Jersey, have invented a certain new and useful Improvement in Hemmers for Sewing-Machines, of which the following is a full, clear, and exact description.

The object of this invention is to provide a sewing-machine hemmer with means for presentingthe hem fold to the initial action of the cloth-feeding and stitch-forming mechan- ISIIl.

Prior to this invention the operator when I 5 starting a hem was obliged to advance the material through the folding-scroll .by the use of somepointed instrumentsuch, for instance, as a small screw-driver, a wire sharpened at one end, or some other device which would pass through the slot between the edges of the folding-scroll. To avoid the use of these more or less inconvenient devices, I provide the hemmer with a slide-plate havinga tongue which enters the folding-scroll at the upper side of the guide-plate and between the hem folds of the material, so that a movement of the slide-plate in the direction of the feed of the material will advance the hem folds to the action of the stitch-forming mechanism.

In the accompanying drawings, illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 isa plan view of a hemmer'used in hem'stitching handkerchiefs supplied with the slide- Fig. 2 is a perspective view of the slide-plate detached. Fig. 3

is a view similar to Fig. 1, except that the slide-plate is shown in its forward position or advanced to present the hem fold to the nee- 4 die action. Fig. 4 is a rear elevation of Fig. 3.

The hemmer comprises a base-plate 1, by means of which it may be secured in position upon a sewing-machine, a supporting-plate 2, secured on plate 1 by screws 3 3, a lug or spacing-piece 5, attached to plate 2 by screws 4 4 and serving as a guide for the edge of the fabric, a guide-plate 6, having an extended portion or tongue 7 notched, as at 8, and an edge-turner or scroll 9, secured to the supporting-plate 2 and bent over and under the 5 edge of the guide-plate 6, leaving a small space through which the fabric is passed as it is fed. to the sewing mechanism.

Heretofore in the use of this hemmer the operator inserted a sharp instrument in the slot 10 in the scroll to advance the fabric for the commencement of the stitching operation. As a substitute for this sort of feed the present invention provides a slide-plate 11, adjust- .ably secured to the guide-plate 6 by a screw 12, passing through a slot 13 in the guideplate and held against vertical displacement by a nut 14:. The slide-plate 11 at its free end 15 is of substantially the form of the free end 16 of the guide-plate 6, the oppositeend 5 17 of said slide-plate being narrowed to pass through the folding-scroll and rest upon the upper side of the tongue portion 7 of the guideplate 6. The end 17 of the slide-plate is shown as provided with teeth 18 to insure its hold on 7 the material, and while this form of construction is desirable it is not essential to the practical operation of the device, since the eX- treme point if slightly beaked would effect the desired result. The operation is as follows: The slide-plate 11 is first adjusted as illustated in Fig. 1, when the fabric is brought under and around the free ends 15 and 16 of the slide-plate 11 and guide-plate 6 until the edge of the fabric 0 abuts against the spacing-piece 5, when the fabric is passed forward until it enters the folding-scroll sufficiently to be acted upon by the end 18 of the'slide-plate 11. The slideplate 11 is then moved forward to the posi- 5 tion shown in Fig. 3, carrying the fabric with it by virtue of the engagement therewith of its toothed end 18, thus presenting the hem fold to the action of the stitch-forming mechanism, and after the commencement of the 9 stitching the slide-plate is again returned to its normal position, as illustrated in Fig. 1.

What I claim is- 1. A hemmer, having a supporting-plate, a folding-scroll attached thereto, a guide-plate, and a slide-plate movably secured to the guideplate and having an end passed through the folding-scroll and adapted to enter the hem fold of the material to advance it to the action of the stitch-forming mechanism, the said slide-plate is manually moved in the proper direction.

2. A hemmer, having a supporting-plate, a guide-plate having a tongue portion, a folding-scroll inclosing said tongue portion, and a slide-plate mounted upon the guide-plate and having a narrow end passed through the folding-scroll above the tongue portion of the guide-plate, said slide-plate movable manually in the direction of its length to advance the folded material to the action of the stitchforming mechanism.

plate movable manually in the direction of its:

length to advance the folded material to the action of the stitch-forming mechanism.

In testimony whereof I have hereunto set my hand this 25th day of May, A. l). 1904;. JOHN \V. ESHICIJMAN. \Vitnesses:
