a-- we W WILLIAM T. JOHNSTON, OF OTTUMWA, IOWA.

Specification forming part of Letters Patent No. 31,277, dated September 10, 1872.

To all whom it may concern:

Be it known that I, WILLIAM T. JOHNSTON, of Ottumwa, in the county of Wa-pello and State of Iowa, have invented a new and Improved Gathering Attachment for Sewing-Machines 5 and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specifica tion, in which-'- Figure 1 is a view of one side of the device as it appears when the needle-bar'is raised to its highest point. Fig. 2 is a similar view of the same parts shown in Fig. 1 as they appear at the termination of the lower stroke of the needle-bar. Fig. 3 is a perspective view of the device.

Similar letters Of.1'6f61'61106 indicate corresponding parts in the, several figures.

This invention relates to improvements on mechanism designed for gathering or rufflin g; and consists in an adjustable vibrating yoke between which the head of the needle-bindin g screw on the needle-bar plays in combination with a gathering-slide and a pressure foot, as will be hereinafter explained.

The following description of my invention will enable others skilled in the art to understand it.

In the accompanying drawing, A A represent the frame of the device, to one end of which a pressure-foot, B, is secured. To the standard portion, A, of the frame a vertical- ]y:vibrating yoke is pivoted at g, which yoke consists of two curved arms, 0 0, and a connecting-plate, a. The plate a is pivoted, at 0,.

to the free end of the lower arm 0, and connected to the upper arm 0 by a movable pin, which allows the ends of the arms to be adiusted nearer together or further apart, accordin g to the length of strokes which it is desired to give to the gathering-slide a. The gatherin g-slide is a thin forked piece of metal, slight- 1y curved, and secured to an arm, h, so as to work beneath the pressure-foot B and against ed, at i, to an extension, f, of the yoke-arm C,

the length of the strokes being regulated by the connecting-pin of plate a, as above explained.

The device above described, if detached from the pressure-foot B of a sewing-machine, may be secured to the cloth-plate, or it may be secured to the overhanging bracket of a sewing-machine, provided always the slide a be adjusted to work between the pressure-foot and the cloth-plate, and the head of the needlescrew on the needle-bar be arranged between the two arms (3 C so as to alternately strike them.

.It will be seen from the above description that my gathering device is operated by the rise and descent of the needle-bar, and that the needle passes through the gather last formed and holds it before the slide a is caused to recede from such gather.

Having described 1n yinvention, what I claim as new, and desire to secure by Letters Patent,

substantially as and for the purpose described.

TVitness my hand inthe matter of my application for Letters Patent for gathering at tachment for sewing-machines.
