HEMMER FOR SEWING-MACHINES.

F PECIJE'ICATION fQrming part of Letters Patent No. 351,762, dated November 2, 1886 Applicationfiled March 6, 1886. Seria1No.194,259. (ModeL) adjustable part properly bent. Fig. 3 is a front edge view of Fig. 2. Fig. 4 is a perspective view showing the improved hemmer applied to a scroll-bearing extension of a foot of a' sewing-machine. Fig. 5 is a perspective View ofthe foot, its extension, and scroll, without the adjustable portion represented by Figs. 1, 2, and 3. Fig. 6 is a vertical section through Fig. 4 in the plane indicated by the dotted lines, Fig. 4. Fig. 7 is a perspective view showing a modification of my device. Fig. 8 is a plan View of the scroll D and footextension B, having the portion A, Fig. 6,

cut off. Fig. 9 is abottom view of the presser- .foot and scroll, and Fig. 10 represents the scroll in blank form before it isbent into shape.

This invention relates to improvements in sewing-machine hemmers; and my object is to construct a hemmer in a novel manner, which is adjustable for different widths of hems, as will be fully understood from the followingde script-ion when taken in connection with the annexed drawings.

Referring to the accompanying drawings, A designates the presser-footlfor a sewing-Inachine, and a the vertical aperture through which the needle plays. At the toe of this foot is a transverse guiding ridge or rib, b, and from this toeiproj ectsadepressed angular portion, B, terminated by a narrow rib, 12, between which latter and the broad rib bis a transverse groove, b for apurpose hereinafter explained,

the floor of which is perforated vertically,and such perforations screw-tapped to receive a binding-screw, 0, (shown in Figs. 4 and 7.)

D designates the tapered scroll for turning the inner edge or fold of the hem. This scroll is secured to the oblique or beveled edge of the slotted extension or angular portion B by brazing, soldering, on Many other suitable manner, so that the top of said portion and scroll are near alevel. a bottom portion, 0, a top portion, 0, and an intermediate tapered tongue, 0, at the lefthand side of whichis a notch, 0 The right hand side of this scroll presents the longitudinal spacesthat is to say, the edges of the portions are disconnected. The right-hand corner, c, of the top portion, 0, is turned up so as to prevent the cloth from catching at this 'point. 7

I will now describe my improved adjustable portion E of the heinmer, shown finished and attached to the angular foot-extension in Fig.

' 4. This portion E, like the scroll D, is formed; out ofa thin metal plate, and consists ofa bottom portion, (7, a top part, (1, having parallel slots d d through it, and bars d d d, the mid dle'one, d of which is marked off to form a gage orrule by which the heminer can be adjusted for different widths of hems.

' Between the bottom and top portions is a narrow tongue, (1, which is aboutequal in Width to the width of the front bar, d", and lies directly beneath it and has its free end turned down, as shown in Fig. 3 at e. tongue serves to hold up the top fold of the cloth on its way to the scroll D and to keep the cloth smooth and even, and the short curve 6 somewhat stiffens this tongue.

In addition to the parts of the cloth-guide E, above described, there is a part, d which 'is directly above and parallel to the bottom portion, (1, upon which part (1 the extension B and scroll rest.

By reference to Fig. 4 it will be seen that the two rear bars, d d, lie in the grooved portion of the foot-extension or angular portion 13, and are guided by the two ribs 72 b thereon, that the binding-screw O is used to rigidly secure the adjustable cloth-guide E to said angular portion, and that the upturned corner or lip 0* of the scroll D rises through the slot d, so that it will not interfere with the passage or feeding of the cloth. It will also be seen that by simply loosening the binding-screw G the device E can be adjusted endwise, either to the right or left, and set by the rule-marks on the bar (i above described, for turning any de- This scroll consists of This.

sired width of hem, limited only by the length of the device E.

It will be further observed that the tongue d being made narrow, will not interfere with 5 the application of the extension or angular portion B and its scroll D, and that the operator can view the front end of the scroll through the slot (1.

By reference to Fig. 8 it will be seen that I employ that portion \vhichIhave denominated the extension B, independently of the presser-foot A. In this modification I make said extension and its scroll precisely as above described, but do not attach it to the foot-,which latter may be made in the usual well-known manner. Instead of using the foot as a support for the hemmers I employ a bent-plate, G, the portion g of which is slotted to receive a binding-screw, that secures it fast upon the bed-plate of the sewing-machinc. The narrow raised tongue 9' is perforated and adapted to be received on top of the adjustable portion E of the hemmer, between the two ribs b b of the angular portion B. The single binding-screw thus serves to secure the portion B and the hemmer E to the overhanging tongueg' of the plate or bracket G, and by loosening the screw which passes through the slotted portion g of the plate G the operator can sew as near'to the edge ot the hem as desired.

By loosening the binding-screw O the clothgnide E can be adjusted toward the right or left hand for different widths of henis. It will thus be observed that my improvement may be applied directly to a pressure-foot or to a separate support adj ustably secured upon the bed-plate of a sewing-machine.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

on its right-hand side, and a notch, c", at its lower left-hand corner, the cloth-guide E, having rule-marks on one of its bars, a bindingscrew, and a support on a sewing-machine for said devices, substantially as described.

3. The combination of the angular portion B, formed with ribs 1) b, the scroll portion D, constructed as described, with the upturned corner 0, the slotted adjustable cloth-guide, also constructed as described, and the binding-screw G, substantially as specified.

4. The cloth-guide E, formed of a single piece, and consisting of the bottom portion, (1, a top part, d, slotted as described, a part, (1, directly above the bottom portion, d, and a narrow tongue, (1 curved at e, in combination with the ribbed angular portion B, having the scroll secured to it, and formed as described, and the binding-screw 0, all constructed and adapted to operate substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.
