IMPROVEMENT IN TUCKERS FOR SEWlNG-MACHlNES.

Specification forming part of Letters Patent No. 132,235, dated October 15, 1872.

To all whom it fmay concern:

Be it known that I, JOSEPH H. BEAN, of Cincinnati, in the county of Hamilton and l State of Ohio, have invented a new and Improved Sewing-Machine Attachment; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.

This invention consists, mainly, in the combination of two adjustable hook-plates with a main stationary plate, the hookplates being so constructed that both are held, when in the desired position, by a single set-screw. It further consists in other details of construction, which will be fully described hereinafter.

.In the drawing, Figure 1 represents a plan view of the main plates 5 Figs. 2 and 4, plan views of the adjustable hooks; Fig. 3, a plan view of the shield; Fig. 5, a perspective vievlT of the knob or set-screw; Fig. 6, a plan View of the machine complete; and Fig. 7, a side elevation of the same.

To enable others skilled' in the art to make and use my invention, I will now proceed to describe fully its construction and operation.

A represents the main plate, having the arm c provided with the slot al, and extension c2 providedl with the slots a3 a, as shown. The slots a3 a4 are formed by properly cutting the plates and bending the metal downward out of the way, by which means, also, supports .5 a5 a a6, Fig. 7, are formed for the plate to rest upon when in place. Similar supports a7 ci' are also formed upon the sides of the plate by bending down lines of projecting metal, as shown. The arm a is provided with suitable distance-lines, regularly numbered each way from a line marked 0, as shown. B represents one of the hookplates, consisting of the hook proper b, arm Ill-having the slot b2, and catches b3 b3, as shown. C represents the other liook plate, consisting of the hook proper c, main portion cl having the central pin c2 and vertical guides c3 c3, and arm c4 having a iiange, c5, as shown. D represents a threaded knob or set-screw, adapted to fit a threaded pin, c2, of the hook-plate C. E represents a shield-plate, consisting ofthe main portion c having the slot el, arm e2, and guide e3. When these parts are put together the arm b1 of the hook-plate B lies beneath the arm a of the plate A, its

catches b3 b3 serving to hold it in place at one end and still permit it to slide freely. The hook-plate C lies beneath the arm of plate B, its guides c3 c3 extending up through the slots in plates A and B. It is held in place by the knob D, and being below the plate B it serves to support the inner end or" that also. The shield E is located upon the top of the plate A, and is also held by the knob, as shown.

The manner of using my improved tucker is as follows: It should be secured upon the ma: chine by means of the gage-screw, with the line marked 0 upon the plate A in a direct line with the needle. The slots a3 a4, designed for the gage-screw, adapt it for useA upon different machines. If it is desired to have the tucks meet, place the inner guide c3 in line with figure] upon the main plate A, andthe left hand or outer arm of hook B inline with ligure 8 upon the other side of the line 0 upon the plate A. By moving the hook e to figure 2 and hook B to figure et the tucks will be wider and yet meet. Ii' a space is desired between the tucks, move the hook B to the left, leaving hook C stationary. To put the cloth in the tucker, fold it at the edge so as to about iill the space between the hooks; then slide it from the left until the right edge ot' the cloth comes into the right hook; then put the left edge in the left hook; now adjust the cloth so as to just ll the space evenly; let down the presserfoot, and all is ready. When making the tuck the edge of the goods should be held in the left hand and the Jfolded edge in the right, and the space between the hooks kept f ull and the tucks made will be perfectly straight and all of one width. When the first tuck is made turn it to the left, place the edge of it in the hook B, fold the goods under and fill the space between the hooks as before, keeping the space just full, which is easily done, and the work will be perfect and always the same in width. The tuck may be commenced one, two, or three inches from the edge of the dressskirt, by placing the edge of the hem in the hook B and sliding it to the left the desired width. As the gage-hooks B and C are held in place by the setscrew D when the tucker is adjusted to the machine, it remains stationary, and there is no danger of altering the proper position when the Width of the tuck is changed.

Some ofthe advantages possessed by the construction described are as follows: By means of the supports of the main plate A it is held up sufficiently for the cloth-plate to relieve the hooks from pressure and permit them to be readily adjusted. The extension of the hooks beyond the line of the main plate toward the operator is advantageous because the work is much more easily 'placed in the tuclrer than if they were entirely beneath the main plate. The advantages arising` from this construction will be more readily understood, perhaps, if it is considered that in placing the cloth in the tucker a portion of the cloth must be placed in each of the hooks and a portion must pass under the hook B. The peculiar construction of the hook-plate C, with its arrn c4, instead of a continuation of the hook, enables the device to be used for making the nest' tucks. The shield E covers the arrn c4 and prevents the goods from crowding over the arm after leavin g the needle. rEhe device is very simple in 1 its construction, and can be made at a small cost.

Having thus fully described my invention,

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

1. The combination of the hook-plates B C with the plate A and set-screw D, the plates B U being both held in place upon the plate A by the screw l), as described.

2. The hook-plate U, having the arm c4, with supportingdiange c5 arranged in such relation Witnesses:
