SPECIFICATION formingpart of Letters Patent No'. 629,339, dated July 25, 1899.

i Application tiled April l, 1899. Serial No. 711,332. (No model.)l l

To @ZZ whom t may concern:

Be it known that, Gossip M. CLAPPER, a citizen ofthe United States, residingl at Axline,` in the'county of Muskingum and Statev of Ohio, have invented a new' and Y'useful Shears, of which the following is a specifica-l This invention relates to shears, and more especially to that class thereof employed for cutting or clipping the wool of sheep and other animals; and the objectof the invention is to provide a simple, light, and inexpensive article of the character specified To enable others to understand thelinven-V tion, l have'i-llustrated the preferred embodiment thereof in the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a top plan view of shears constructed in laccordance with my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a detail in perspective of the clampingspring. Fig. 4 is a transverse section taken through the center ofthe spring.

Like characters'denote li ke and corresponding parts in each of the several liguresof the drawings.

The shears represented includes in its construction the juxtaposed cutter-plates C and C', which may be made of any suitable material and which are provided at theirfront ends with projecting bars or' teeth 2 bf tapered form and which are beveled along-their opposite angular edges to produce cutting portions, and the cutting portions of the up,-

per series of bars or teeth project in opposite directions to those on the lower set. The lower plate of the device is held stationary, while the upper plate is reciprooated across the same, so that the sharpened edges of the respective projecting bars/2 can cooperate to cut or clip the wool or hair of an animal, and

complshed. y .The handle of the shears is denoted by H, being formed from a single length of fiat spring metal bent intermediate of its ends into substantially U shape, the opposite branches or members 8 and 4, respectively, having their extremities l0 twisted transversely at right angles to the plane of the respective members 3 and 4, so as telit flat `against the outer faces of the-respective cutthisoperati'on can be rapidly and cleanly aca l ter-plates() and C', to which said connecting l ends are fastened by rivets 1l or other suitable fastening means'. By twisting the ends of thel handle the dat sides thereof are disposed in aV convenient position for operating the device., One of the members, as '3, is preferably bowed outward slightly, as shown in Fig. l, and is adapted to be held in the Y palm of the hand, the bowed portion fitting evenly Within the palm. The opposite inem- `ber 4 has a convolute form to accommodate the ngers of the hand, whereby the two members are given a shape to conveniently it the hand of the operator.

Ordinarily the branch 3 of the spring-handle H will be held in the hollow of the hand and the iingers will press the cooperating branch 4 inward, thereby moving the upper bars or teeth 2 across their companions, and consequently compressing said branch 4, so that when it is released it can retract by its own action, and thereby return the several upper fingers to their initial positions, at which point the operation will be repeated.

The pressure between the plates O and C is regulated by the dat bowed spring 5, having openings 6 near its 'opposite ends to receive the bolts 7, carried by the under plate C. These bolts extend through longitudinal slots 8 in the upper plate and are provided above the upper surface of the spring 5 with nuts 9, adapted to bind against they spring 5 and adjust its tension upon the upper plate, and consequently to vary the contact of the latter with its companion. The opposite ends of the spring 5 bear firmly against the upper plate at points beyond the clamping-bolts and serve to hold said upper plate withthe proper degree of pressure, which can be va.-

spring 5. As the olipper'is in use the'cutting edges of the bars or teeth 2 are selfsharpening, and the contacting faces of the parts are worn away somewhat in operation;

but this can be compensated for by tightening the spring, thereby insuring tbeproper contiguty between the two parts.

The shears constructed as aforesaid can opcrate with rapidity and can do close smooth work, and it will be evident that they are light and consist of a small number of parts, which can be produced and assembled for use at a low cost.

Changes in the form, proportion, size, andY the minor details of construction within the scope ot' the appended claims may be resorted to without departing from the spirit or sac riiicing any of the advantages of this invention. i

Having thus described the invention, what I claim isl. A shears consisting ofv two juxtaposed cutting-plates carrying coperating teeth, means for holding said plates in contact, and a handle consistingof a flat U-shaped spring having its ends bent transversely to its shoulder and secured to the outer faces of the j uxtaposed plates, one branch of the spring being slightly bowed outwardly so as to fit-within the palm ot" the operators hand and the other branch having a convolute form to accommodate the operators lingers.

2. The improved shears herein described andshown consisting of two juxtaposed plates carrying coperating teeth, one of said plates being provided with transverse slots, a bowed spring extending over said slots and having its ends bearing on said plate beyond the slots, bolts carried by the non-slotted plate and projecting through said slots and the spring, thumb-nuts mounted on the said bolts and bearing against said spring, and afhandle consisting of av tlatU-sh'aped spring having its ends twisted in a plane at right angles toits shoulder andl secured to the outer faces of the juxtaposed plates.

In testimony that I claim the foregoing as my own I'have heretoatfixed my signature in the presence of two witnesses.

GUSSIE M. CLAPPER.
