HORSE-SPECULUIVL Specification of Letters Patent.

Patented Jan. 15, 1907.

Application filed April 24,1906. Serial No. 313,495.

To all whom [it may concern.-

Be it known that I, J OHN SKLAR, a citizen of the United States, residing at Brooklyn, in the county of Kings, State of New York, have invented new and useful Improvements in l-Iorse-Speculums, of which the following is a specification.

This invention relates to certain improvements in horse-speculums.

This invention resides in certain details of construction set forth in the following speci- 1 fication and claims and illustrated 1n the annexed drawings, in which- V Figure 1 is a side view of a horsespeculum embodying this invention, Fig. 2 is a plan view showing one end of a bit-piece in section. Fig. 3 is a part of a check-piece or jaw, showing the hole for a pivot and the hole for engagement by the tail or bracing end of the spring or spring-coil. Fig. 4 is a detail view of a spring. Fig. 5 is an edge view of Fig. 4.

In the drawings are shown the sections a of a cheek-piece of horse-speculum hinged together at I).

A ratchet-rack is shown at c, which is movably held in engaging position by a spring (Z, which spring presses against a stud e on the rack to move such rack to engaging position.

The spring (Z of each rack comprises acoil part 72., which has a downwardly-extended part or tail end f, which tail is extended into a hole 9 in one of the cheek-pieces, as shown in Fig. 3, to hold the rack toward engaging position. The screw 'i, which forms a pivot for the I rack, is extended through the spring-coil 7L and fastened in the internally-threaded hole or tap it.

Bit-pieces are shown at m. These bitpieces are terminated at each end by a keyhole-shaped slot adapted to slip 011 and off the stem n in one direction. These stems are somewhat flattened, so that when given a quarter-turn the bit-pieces will be locked to or prevented from becoming disengaged from the studs n or aws or cheek-pieces a, carrying studs n. One jaw of each pair has a loop 0, which forms a steadying means for the free end of the rack 0. Each loop has a steel pin 29, forming a stop or engaging point for the rack or its teeth. These loops are secured by rivets or fastenings, (shown at g.)

The pins or studs 6 are suitably headed, so that the free or active end of the spring (Z slipped under the head will be held against accidental disengagement. Cap-pieces r on pivots i cover the brace end of the spring.

The speculum can be readily assembled or dismounted or its parts separated when not in use or to be cleaned.

The racks can be united by a hand-chain 8, serving to release both racks at once when the jaws are to close.

I claim- 1. A speculum comprising jaws, one of which has a pivot and a spring bracing-eye in proximity to one another, a rack having a pivot-hole of such size as to embrace or surround both said pivot and eye in the jaw, an engaging spring for the rack having an end seated in said bracing-eye, and a cap-piece on the pivot to conceal or cover the pivothole with the inclosed brace end of the spring.

2. A speculum comprising aws and bits, said parts having slotted or keyhole-shaped engaging portions permitting disengagement in one position but securing the parts when the bits are in position for use.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
