vBe ist knownhtha-t 1, ABEL H. BARTLETT, of Sipuyten Duyvil,.in` thecountyof:Westchester and State ot NewYork, jhavewinlvented newf1 and luseiulvImprovementsfftn Remmers ,L and I l do hereby declare that the follow-ingiis; a fulfl,

clear,y and exact description thereof, which? will enable others skilled in the art to make .and use thesame,reference beinghad to the` accompanying drawings, formin of this' specification.

This invention relates to improvements `in' that class of hemrnersfor .sewing-machines which are designed for markinghems of differ-1 ent widths, and which are attached to the presser-foot. My invention relates to hem'mers for sewingmachin'es; and it consists in certain improvements thereon, which will be first fully described in connection with all that is necessary to their clear understanding, and then specified in the claims.

Figure 1 represents a front elevation of my improved hem mer. Fig. 2 is a plan view ofthe same. Fig. 3 is a transverse section on the line :c x of Fig. 2. Fig. 4 is a transverse section on the line y y of Fig. 2. Fig. 5 is a section on the line z z of Fig. 4, looking in the direction of the arrows shown in Fig. 4. Fig. 6 is a front elevation ofthe same when arranged lfor the cloth-supporting plates to be used instead of the cord. Fig. 7 is a. front elevation of one of the plates used to support the cloth in the space between the two parts of the former when the latter is separated; and Figs. 8 and 9 are views of two ot' said plates, the same being inverted. i

Similar letters of reference indicate corresponding parts.

A represents a hem-folding and guide plate for aiding in folding the edge of the cloth and guiding it after it has been folded and turned under to the needle. Itis made semicircular, or nearly so, at the receiving end B, and ter` minates next to the needle in an angular form, as shown at C. This grooved guiding-plate is connected to or made a part of a plane plate, D, by which it is to be attached to the plate E, which is a prolongation of the presser-foot F. The connection with this plate E is made by a clamping-screw, Gr, and a stud, H, which enter slots in the end of plate E, to be secured by the clamping-nut, so that the attachment l oraremolval may be effected wit-hout takin gthe clam-pin.glinutL out of plate D.

21. `The front end B1 ofthe guide A is provided with aiblock or plate, I, which, together with the block or plateK, I call the folder,77 over 'Swhfioli threxclothfis-.to beturned to form the foldl of' the hem, the widthofwhich `is to be fgoyerned' yby theseA plates. The plate K is .nfiounftedE on a-x long .arm,L,forlnedl from one i edge ofia; plate, M, bent' perpendicular to the saidplate, so that when the latter is clamped between thevrguildefA and the plate Eby the -clampingescrew Gr: passing through aslot, N, in it theA said arm will rest onv the platey of the machine in front of the end B of the guide A and perpendicular to it. The said arm L is separated from the plate M by a space, O, twothirds, or thereabout, the length of the plate M. Beyond the end of the arm L to which the plate or block K is attached the plate M is bent around the convex side of plate K, as shown at P, to form the cloth-guide for the outer edge ot' the fold and for turning the cloth in making the first fold. .These two plates or blocks I K form a divided and extension folder, which, when brought close together by adjusting the plate M valong the. plate D and clamping-screw Gr to the required position, form the interior wall of a scroll-groove, Q, in which the cloth is turned to form the hem. The outer wall of the groove is formed by the bent endP of the plate M, a part of the top of the latter, and the guide A. These two parts I K are designed to he, when reduced to practical form, of the proper size to form the narrowest hem to be made when placed close together, and by separating them more or less Widely apart it is designed to make hems of any required width. When making wide heins it is necessary to support the cloth belevel with the same. This may be donein various ways. For instance, a cord, B, of any kind may be attached to the top of plate K, extended to the top of I, passed through it in a hole so arranged that the cord will pass out at the bottom on the opposite side, and thence along the arm L to a spring, S, beyond, for holding it' taut, the arrangement being such that in adjusting the plates M and K along one way or the other the cord will run through the plate I freely.

Instead of the spring S, the cord may be ati tween the tops of the two parts of the folder,-

tached to any other support., and the slack which occurs by thestretching of the cord may be taken up from time to time; or, instead of the cord for supporting the cloth, plates T, made in different lengths for hems of different widths, may be used, the said plates being provided with long arms U, with langes V to it in the channels in the arms L, formed by turning up one edge, as shown at W, so that the plates T may slide into or out of position between the plates I K; orthese plates'lmaybe made without the arms U, and hinged or otherwise attached to the arms L, so as to lie down on a projecting and supporting flange arranged above the table of the machine when not required for use, and be raised up for use and supported in any approved Way. They may be made in short sections for the hems of ditferent widths when arranged in this lastinentioned way, and one or more sections may be raised up for use, as required. The plates 'lwhether made to slide in and out or hinged to be raised up for use, as described, may be arranged in speciticlengths and have the same marked on them in igures, so that the required plate for a specitied Width of hem may ne readilyVV selected, and the plates I K may be readily and accurately adjusted by it.

The object of the stud H in the plate D is to act inV conjunction with theclamp-screw G to prevent the said plate D and the plateMfrom being turned on the screw; and the object of shaping the folding and guiding plate A so as to terminate in the angular form shown is to provide a Hat level surface on which the fold, after it has been completed, may slide along toward the needle, close up to the vertical part of plate A, which here assumesthe character of a guide, against which it is desired that the fold shall move, so that the said vertical part shall. govern the distance of the line of stitchingjfrom the edge.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of plates I K with the cord R, for the purpose specied.

2. The combination of cord R with tensionspring S, When-relatively arranged in connection with a hemmer, as and for the purpose specified.

lhc above specication ot' my invention signed by me this 17th day ot' May, 1870.
