GUARD FOR eARBERs SHEARS.

SPECIFICATION forming part of Letters Patent No. 297,964,,dated May 6, 1884.

' Application filed January 18, 1884. (No model.)

To all whom it may. concern.- Be it known that I, ENOOH BATEMAN, a citizen of the United States, residing at Rockford,

, which are specially designed for the use of barbers, and in which a guard is provided to hold 7 the hair in proper relative position to the blade.

The object of the invention is'to provide a pair of shears of this class possessing superior advantages in point of simplicity, inexpensiveness, durability, and general efficiency, whereby, in cutting, the hair will be held in proper position, and will be effectually prevented from slipping away from or along the cutting-edge.

A further object of the invention is to provide a guard which will act to secure a true and even operation of the cutting-edges.

To this end the invention consists, broadly, in providing one of the blades of the shears with a guard-plate having a toothed or serrated edge extending along the cutting-edge of the blade and projecting from the same.

This guard-plate is secured against the blade of the shears by means of the pivot pin or screw, and in such a manner that it acts with a spring-tension against the head of said screw, to retain the blades of the shears together and cause their cutting-edges to run true and even, substantially as will-be hereinafter more fully set forth. r

In theiilrawings, Figure 1 is a side view of a pair of shears embodying my invention. Fig. 2 is another side view taken from the opposite side, showing the blade extended. Fig. 3 is an edge view of the same. Fig. 4 is a longitudinal sectional view taken centrally through the pivot-pin. Fig. 5 is a detail transverse sectional view taken on the line as m, Fig. 1. Fig. 6 is a detail perspective view showing the guard-plate, a portion of the blade to which it' is secured, and the means by which it is secured in position, all the parts being-detached.

Corresponding parts in all the figures are denoted by the same letters of reference.

I Referring to the drawings, A and B designate, respectively, the blades of a pair of barbers shears, which are mainly of the ordinary construction, and are pivoted together by the usual transverse pivot or fulcrum pin, 0.

D designates my improved guardplate, which is secured against the outer face of the blade B, that will be next to the head when the shears are in use, and the edge of this guard-plate corresponding to the cutting-edge of the blade B is toothed or serrated, asshown at d. This edge at projects from the cuttingedge 7), and the guard-plate preferably corresponds to the width and general contour of the outer face of the said blade B, and fits closely and neatly against the same. The guard-plate is secured to the said blade B by the pivot pin or screw 0, which passes through a correspond ing perforation, d, provided in the guard-plate at its inner end, d The inner end or portion, ri is adapted to normally set a slight distance from theface of the blade B, and is formed with a spring or. elastic tension, so that when the pivot pin or screw 0 is screwed home it will act against this spring-tension to force this end d toward the face of blade B. By this arrangement the spring-tension of the guard-plate acts against the face of blade B and the head of the pivot-screw G, to retain the blades A and B neatly together and to allow them to give slightly, whereby a true and even relative action of the cutting-edges of the blades is secured. To secure the guardplate from lateral displacement, I provide a small transverse plate, E, which is secured to the face of the guard-plate, at the inner end of the same, by a pin or screw, F, passing through a perforation, e, and into a corresponding recess or perforation, b, in the blade B. This plate E is provided with inwardly-projecting ends e e which embrace the side edges of the myself to the exact construction and arrangement herein set forth, as numerous modifications can be made without departing from the spirit and scope of my invention.

I claim as my invention- 1. The combination, in a pair of barbers shears, with one of the blades, of the plate secured closely against the outer face thereof, and provided with a serrated edge having the serrations projecting slightly from the cuttingedge of the blade, substantially as and for the purpose set forth.

2. A pair of shears having a guard-plate secured in position against the face of one of the blades by means of the pivot pin or screw of the shears, substantially as set forth.

3. A pair of shears embodying the blades,

a guard-plate disposed along the face of one 25 of the blades, a plate arranged at the inner end of the guard-plate, and embracing the said guard-plate and blade, and a pin or screw securing this plate in position, substantially as set forth.

4. A pair of shears having a spring-plate secured against the outer face of one of its blades by means of the pivot pin or screw of the shears, the said plate being compressed by the pin and caused to exert its tension to se- 35 cure an even movement of the cutting-edge of the blades, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ENOGH BATEMAN.
