ATENT SEWING-MACHINE ATTACHMENT,

SPEGIFIGATION forming part of Letters Patent No. 249,733, dated November 22, 1881.

Application filed August 20, 1881. (No model.)

To all whom it may concern Be it known that I, WILLIAM A. ALRICI-I, of Ghatham, in the county of Pittsylvania and State of Virginia, have invented certain new and useful Improvements iuSewiug-Machine Attachments; andI do hereby declare that the following is a full, clear, and exact description of the invention,whieh willen able others skilled in the art to which it appertains to make and use the same, reference hcin g had to the accompanying drawings, which form a part of this specification.

This invention relates to a ripping attachment for sewing-machines, the construction and operation of which will be hereinafter more fully described, and particularly pointed out in the claim. 1

My invention consists of a narrow sharp blade capable of being secured in the needlebar of any ordinary sewing machine, and operated by the mechanism of such machine, so as to cut or rip seams previously made in an easy, convenient, and effectual manner.

In the drawings hereto annexed, Figure 1 represents my invention as attached to a sewing-machine, of which only the head, needlebar, and bed-plate are shown; and Fig. 2 is a perspective view of my improved cutter detached.

Similar letters of reference indicate corre sponding parts in'both figures.

A in the drawings refers to the needle-bar, and to the bed-plate, ofany ordinary sewingmachine.

D is the sharp narrow knife-blade which constitutes my invention, and which is so constructed as to be capable of being secured in the need ereneniae lot the needle-her; Te ef: e t an ear! the sla n knife is mended an l G.

i an Beret ten the nreeeeeie t n e he ereti reathe pat ent; an! time see: a l-re; gr teeeseie enetleet rel he he em senate, llltl areal the tie-tie at eettee ill being attached to the needle-bar of sewingmachines adjoining the needle are not new, such being shown, for example, in the patents to Dwyer, January 2, 1877, and Allen, May27, 1873, and such I do not claim. In these cases the needle, if not removed, will interfere with the operation of the cutter, and a separate openingfor the latter must be cut in the bedplate, which is very undesirable, as, besides weakening the bed plate, it will accumulate dust and lint, and be apt to catch and arrest the progress of goods being sewed.

By myinvention the cutter may be attached to any sewing-machine without making the slightest change in the construction thereof,

and the cutters may be furnished at a trifling cost.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States-- Tbe' combination, with the needle-bar of a sewing-machine, of a knife or cutter, D, having shank 0, adapted to the needle-opening of said needle-bar,by which it may be seciired in said opening, so as to work in the needle-opening of the bed-plate, as herein described, for the purpose shown andspecified,
