IMPROVEMENT IN HEMMERS FOR S-EWING-MCHINES.

Specification forming part of Letters Patent No. 144,333, dated November 4, 1873; application filed July 7,

To all whom -t may concern:

Be it known that I, JOHN M. GRIEST, of Delavan, in the county of Tazewell and State of Illinois, have invented a new and valuable Improvement in Adjustable Hemmers and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specication, and to the letters and figures of reference marked thereon.

Figure l of the drawings isa representation of a plan view of my adjustable hemmer. Fig.

Fig. 3 is a transverse, and Fig. 4 a longitudinal, section of the same.

My invention relates to sewing-machine hemwith an inch-scale on the 0E edge, showing the precisewidth of the nished seam,`the several parts being so constructed as to slide to-v gether without separating. The object of this invention is to improve hemming attachments for sewing-machines of all varieties; and consists in the employment of a flexible or folding support for the upper folded portion of the hem between the adjustable and fixed plates, as will be hereinafter explained; also, in the construction and novel arrangement of In the accompanying drawings, A represents the horizontal slotted portionA of the stationary plate A2, which receives through it a of a sewing-machine. al represents the vertical portion of this iixed plate 5 a2, the overhanging lon gitudinally-slotted portion, which is slotted at a3; and B represents the scroll (r cloth-turner, which is constructed with a turning tongue, b', extended beyond its scrollshaped portion b, as shown in Fig. 3. This fixed plate is also provided with scale fmarks c4 along one of its longitudinal edges, as shown is about the same width as the lixed plate, and is connected to this fixed plate beneath it by means of three clasps, g3, g3, and f, and a tongue, F,which extends from a raised handle at the outer end of plate E over the horizontal and slotted portion a? of the ixed plate, and is riveted to a flange, g2, of a vertical bearingstrip, g. The bearing-strip supports the overhanging portion a2 of the xed plate on the sewing-machine cloth-plate, and it also supports the adjustable plate E free from the cloth-plate, so that the fabric being hemmed will not drag beneathplate E. The inner end of themovable plate E is turned up vertically, and then bent over horizontally at e; and

between the vertical'ly-upturned portion and the bearing `g is a space for the fold of fabric, which is carried beneath the movable plate, and up through said space; thence over the flange e to the turner B, which latter turns the hem on its way to the sewing-machine needle. For the purpose of supporting the fabric from the flange e to the turner B, I em. ploy two jointed arms, C and D, which are connected together by a pivot, and also pivoted, respectively, to the scroll B and flange e. These arms articulate about their joints, so as to fold and extend in accommodation to the adjustments of the plate E 5 and on one of these arms I form a check-lip, c, to prevent this arm sliding over the tongue b. I utilize the clasp g3, which slides over the scale a4, as a pointer to this scale for indicatingl on the plate a2 the width of hem which it is required to make.

It will be seen from the above. description that I employ but two platesr to form the hemmer, on the upper overhanging one oi' which theV turner B is formed and the indicating'- scale applied, and on the lcwer sliding one of which the gage is formed, against which the folded edge of the cloth is guided.

It will also be seen that I employ one of the clasps g3 as a pointer for the scale a4; also, that I support the sliding gage-plate E, as well as the overhan ging fixed plate a2, by means of a bearing, g, which is connected to the tongue F of the gage-plate, and movable with it. I finally employ an extensible cloth-support between the xed and stationary plates.

What I claim as new, and desire to secure by Letters Patent, is-

tensible jointed arms C and D, substantially as shown'and specified.

In testimony that I claim the above I have hereunto subscribed my naine in the presence of two Witnesses.

Witnesses: JOHN M. GRIEST.
