HEMMING AND TUCKING ATTACl-lMENT FOR SEWING-MACHINES.

- SPECIFICATION forming part of Letters i'atent No. 423,452, dated March is, 1890.

7 Application filed July 22, 1889- Serial No. 318,315. (No model.)

To all whom it may concern.-

' Be it known that I, DAVID SNYDER, of Fall River, in the county of Bristol, State of Massachusetts, have invented a certain new and useful Improvement in Combined Hem and Tuck Attachment for Sewing-Machines, of

which the following is a description suffithe attachment in use as a tucker; and Figs. 4.,

5, 6, and 7, sectional-views illustrating certain details of construction. A

Like lettersand figures of reference indicate corresponding parts in the diiferent figures of the drawings.

My invention relates to an attachment forsewingqnachines, whereby the material may be folded and guided to form any desired width of tuck or hem; and it consists in certain novel featureshereinafter fully set forth and claimed, the object'being to produce a simpler, cheaper, and more efiective device of this character than is now in .ordinary use.

The nature and operation of the improve ment will be readily understood by all conversant with such matters from the following explanation.

In the drawings,.A represents the machinetable, B the arm, and O the presser-foot, these parts being all of the ordinary form and construction. A clamp 1), provided with a setscrew b, is adapted to receive the edge of the table A, the inner end of said clamp being provided witha vertical arm or standard 01. A hook shaped rod H has its long arm f fitted to slide longitudinally in a suitable opening near the top of said standard, said arm being held in'position therein by a set screw g. A flat plate or scale J, provided with a reduced and rounded end h, has its upper surface spaced by longitudinal parallel lines 2', the spaces between said lines preferably representing one quarter of an inch. Atube k projects laterally from the edge 1 of said scale, said tube being adapted to. receive the short arm at of the rod H, upon which-it is adjustable longitudinally of the rod, butlaterally of the plate. The edge 10 of said scale J is-provided longitudinally with a socket'q, (see Fig. 7,) in which a guide-bar 1' is'fitted to slide. A horizontal plate L is provided at one edge with a vertical arm t, the upper end of Whichis fitted to slide on the. arm f of the rod H, and is secured thereon by a set-screw o. A clamping-loop w, provided with a thumbscrew as, is disposed at the opposite edge of the plate L. l

p The hemmer proper M consists of a plate adapted to be adjusted longitudinally in the clamp w.

ward upon itself, as shown in Figs. 5 and 6. A portion of the second or inner fold is cut away at 15, as shown in Figs. 3 and 6, the purpose of said folds being to guide and fold under the raw edge of the cloth in hemming.

In the use of my improvement the device is attached to the table A by its clamp D, so that the edge 16 of the scale-plate J is opposite or in front of the presser-foot O. When employed for hemming, the width of the hem desired is ascertained on the scale-plate, the

example shown in Fig. 2 being seven spaces from the plate edge 1), representing one and three quarter inches. justed in the standard d,"so that the corresponding space-line is directly opposite the machine-needle. The hemmer proper M is adjusted in its clamp w, with the outer edge of its head 2 registering with said line. The cloth K to behemmed is passed under the scale-plate J' and turned upward over its edge 17 (see Fig. 2) and the bar 4" Withdrawn its entire length from its socket in said plate. The raw edge 17 of the cloth is then directed into the head z of the hemmer proper and passed around its inner fold, as shown in Figs. 5 and 6, which serves to'turn it under. The cloth being fed to the needle, the hem will be stitched. at 18 through its raw edge. (See Fig.2.) The plates J Mserve to form the hem the same width as fast as the cloth passes, and the rod 0, extending beyond the needle One end 2 of the plate M is extended laterally and twice bent or folded in-:

The rod H is then ad-.

and iuclosed within the hem, as shown, prevents the cloth from twisting or curving to one side after being stitched, thus forming a crooked or uneven hem.

In tucking, the guide-plate M is inverted and reversed on its clam p w, as shown in Fig.

3, and the rod 1" concealed in its socket. The scale-plate is then adj usted'so that the spaceline 1', representing the depth of tuck to be formed, registers with the needle, the example shown representing two spaces or one-half I inch. The plate M is then adjusted so that its end 19 registers with a space-line double the distance from the edge .19, in the present case being the fourth line. The cloth is folded over the scale-plate, as'before, and under the plate M, and stitched in the usual manner to form the first tuck.

To form succeeding tucks, the cloth is moved toward the left over the scale-plate until the end 19 of the guide-plate bears against the seam of the preceding tuck, as shown in Fig. 3. The plate M serves to guide the cloth as it passes the seam described, engaging the stantially as described.

pocket at its guide edge parallel therewith, a sliding guide-bar within said pocket adapted to form an extension of said guide edge, a I

support for said plate on which the plate is adjustable laterally of the feed, a hemmer proper, and a support for holding said hemmer justable in its support laterally of the line of feed.

2. The combination of a clamp for securing the device to a sewing-machine, a hook-shaped rod adj ustable longitudinally therein, a scaleover said scale-plate, said hemmer being adplate adjustable on said rod, a horizontal 'plate'provided with a clamp, and a vertical arm adjustable on said rod,and a guide-plate adjustable longitudinally in said clamp, sub- The combination ofa clamp for-securing the device toa sewing-machine, a horizontal rod adjustable longitudinally therein, a scaleplate adjustable on said rod, a guide-bar sliding longitudinally in said plate, a horizontal plate adjustable on said rod and provided with'a clamp, and a hemmer-plate adjustable longitudinally in said clamp and provided With a laterally-extended folded head, substantially as and for the purpose set forth.

4. The scale-plate J, havingthe socket q 1 and tube 70, in combination with the rod H, table A, and clamp D, having an'opening for 1 said rod, substantially as described.
