THREAD-CUTTER.

SPECIFIGATION formingpart of Letters Patent No. 727,867, dated May 12, 1903.

Application filed August 6, 1902.

To all whom it may concern:

Be it known that. we, HERMAN A. WEHNER and JOHN J. KEUNST, citizens of the United States, residing at Berlin, in the county of Green Lake and State of Wisconsin, have invented certain new and useful Improvements in Thread-Cutters, of which the following is a specification;

This invention aims to provide a simple and inexpensive device for cutting thread, twine, or the like, and is specially designed to be used by bundle-wrappers, milliners, or any one having occasion to break or sever cord in any manner.

It is customary on the partof the bundlewrapper to part the wrapping-cord after securing the package by a quick jerk of the hands, the continued wear of the cord upon the fingers, however, often causing blistering or soreness of same or like inconvenience. In sewing also much inconvenience is experienced in having to reach for the scissors each time it is found necessary to sever the thread, this being done in innumerable instances, most frequently when the thread end is too short to enable breaking of the same with the fingers.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for edeoting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modificat-ion, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective View of the rear base-plate, showing more particularly how the catch-pin and guard are secured to same. Fig. 2 is a side elevation. Fig. 3 is a plan section on line X X of Fig. 2. Fig. 4 is a front view. Fig. 5 is a modification.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The cutter is designed in its preferred form to be applied to the garment of the user at a point found most convenient and depending much upon the character of work for which Serial Ne. 118,662. (No model.)

it is utilized. However, it may be secured in any suitable manner to the counter in a store or in any place of like character in which it would be a desirable acquisition for the purpose above described.

The device comprises, essentially, a base 1, a spring-guard 2,0f peculiar construction, fastened to the base, and a'cutter or blade 3, also secured to the base. The base in its preferred form is composed of plates-l. and 5,

soldered together: at their edges so as to constitute a hollow body. The plate 4. is slightly convex in form, the guard 2 having itsjshank secured by solder or like means-between the aforementioned plates .4 and 5.-

plates of the base in like manner as the guard -2. The cuttingblade 3 extends outwardly and upwardly from the base, the cutting edge thereof being spaced from and located upon the-base side of the blade. The springguard The shank 'of the catch-pin 6 also is secured between the 2 is formed with spaced members 8 and 9,

poses desirable to have this element secured at the bottom of the base 1 and having the spring members 8 and 9, extending upward, embracing the shank as in the other'form, as shown most clearly in Fig. dot the drawings.

The convex form of the plate 4 gives a finish to the device, also allowing the cord to be held at any angle during the operation of cutting same without any danger of its catching in the edges of the plate, as would be the case were the surface of the same flat. At the lower extremity of the plate 4 and integral therewith is formed the catch 10, the same being bent in approximatelysemicircu lar form and cooperating with the catch-pin 6 in the usual manner. The catch-pin 6 is bent inward at its point, so as to prevent pricking or scratching of the flesh or tearing of goods, which often happens in the usual form of pin having the straight point. It

will be understood that other securing means may be substituted for the catch-pin when it is desired that the cutter be attached to a counter or rigid support. The general shape of the base is immaterial within the contemplation of the invention, the same being made of any shape found best adapted for the puposes of the invention and deemed most suitable by us and may be either plain or fanciful in general contour.

In operation the cord or that which is to be severed is held quite taut and inserted between the guard and blade at the angle formed by the cutting edge of the blade and the said guard. Slight downward pressure will cause the guard to spring inward, and the cord is therefore given a sliding movement along the edge 7 of the blade, which readily parts the same. The principle would be substantially the same as regards the modified construction shown. It is preferred that the guard be composed of the spaced spring members and the shank members be formed of a single piece of material, springwire being preferred, though this is not important within the spirit of the invention, which is susceptible of various modified forms and changes of construction of the separate parts as included within the purview of the appended claims.

Having thus described the invention, what is claimed as new is 1. In an attachment of the character described, in combination, a base comprising front and rear plates rigidly secured together,

a cutting-blade projected from the said base, and a spring-guard cooperating with the aforesaid blade and having its shank portion secured between the aforesaid base-plates, substantially as described.

2. In a cutter for thread and the like, in combination, a-base comprising front and rear plates, the front plate being approximately of convex form and having a catch integrally formed therewith, a blade projected from the front plate of the base, a springguard embracing the sides of the blade and cooperating with the cutting edge thereof to separate the cord, and a catch-pin upon the rear side of the base, substantially as described.

3. In a thread-cutting attachment, a base comprising front and rear plates, a blade projected from the said base and cooperating with a spring-guard secured thereto, said guard comprising spaced members embracing the sides of the blade and formed from a single strand of spring-wire, the shank por tion of the guard being secured between the plates of the base, and means for holding the device in position, substantially as set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
