UNITED STATES PATENT OEEICE.

THOMAS SHAILER, or HADDAM, CONNECTICUT,

TRAP EOE CATCHING ANIMALS.

Specication of Letters Patent No. 3,580, dated May 10, 1844.

they are continually forming new paths which are about three inches below the surface of the earth, in the formation of which they raise a portion of the earth, which enables us to discover the location and direction of their paths. Now if any portion of their path becomes pressed in, they will again restoreit to its former perfection, by `again raising the earth from the disturbed part.` From a knowledge of the last named fact it has occurred to me thata trap might be sprung by the motion of the earth, when raised, as above stated, and that pointed wires might be forced down intothe earth upon them which would secure them until taken away. New the nature of my invennent by entering holes made for that purtion consists in combining those two principles, into the form `of a trap and I willnow proceed to describe its construct-ion and operation. y

In the accompanying drawing, Figure l, isa perspective," andFig. 2, an end view of my trap.

A `represents a sliding board, made to slideup and down `by means of pins one in each end, which enter the slots t, k, in the two posts B, B, which are designed for that purpose and are made stationary to the two end pieces C, C.` From the lower surface of the sliding board A .project a number of wires a, a, a which are there made permapose and by being riveted therein. `These `wires areabout eight inches long, with their lower ends pointed, which pass through holes, bored through the bottom piece I-I, the

ends of which are made stationary to the two end pieces, C, C, and it serves also to keep those pieces at a proper distance apart, and in that manner forms a part `of the frame wo-rk. The `holes throughthe board I-I, are made large enough to allow the wires to slide in them freely as occasion may require. E represents a lever which extends through the upright D, at its lower extremity and is there suspended by a pin which admits of its working in the form of a lever, the pin forming the fulcrum. The upright D is fastened to the cross piece T which is extended across from one end piece to the other, for the purpose of supporting the upright, D and for inserting one end of the Hy lever F, the other end of which enters a notch made near the outer end of the lever E. The flying lever F is connected to the sliding board A by a string or wire which extends `around the top of the upright D, and thus, in connection with the two levers, form the setting part of the trap. The two end pieces C, C, are hollowed up from their lower edges, so that they may be placedupon the path without disturbing it, and that t-he mole may pass under them, without raising the frame 'work of the trap.

To set the trap-in the irst place press i down a small place of the path, then -place the two end pieces C, C, astride the path, and bring that endof the lever F which extends under the trap to touch that part of the path `which has been pressed down. W'ith the fly lever and string in the position described, place two brick, (or their equiva lent in weight) upon the sliding board A.

Its ope-ration is when the mole raises the i earth from its path which has been pressed( down, it also raises that end of the lever E i which extends under the trap, and of course lowers the outer end from the fly lever F, which liberates the sliding board A (and its wires) the weightthereon forces the wires down into the earth upon the mole, one half of the wires passing down on either side of the lever E, which renders thel trap sure though the mole come from either direct-ion.

The dimensions of the trap may be double that of the accompanying drawings.

What I claim as my invention and desire to secure by Letters Patent, is-

In the manner in which I have combined the lever E, one end of which is to rest on the ground, wit-h the sliding board A, and the pointed wires 1, 2, 3, &c., with each other, and with the other parts of the trap, so that the raising of the ground by the mole shall cause the wires to descend, the respect-ive parts being arranged substantially as herein described.
