"GATE.

SPECIFICATION forming part of Letterslatent N0. 282,238, dated July 31, 1883,

- Application filed November 20, 1882. (N0 modelJ objectto provide an efficient and easily operated gate that will automatically operate its own latch mechanism.

In the drawings, Figure 1 tis a perspective view of my improved gate. Fig. 2is a vertical longitudinal sectional view thereof. Fig. 3 is a vertical transverse sectional view.

Referring to the drawings. A designates the frame, which comprises a latch-post, B, two

outwardly inclined uprights, G O, at the rear end, back of which are arranged two auxiliary posts, D D.

E is the gate, which may be of any suitable construction, having end pieces, F F, and

longitudinal rails G. The gate is pivoted between the uprights by a pair of levers, H H,

extending from the top of the gate to acrossbar, I, at the bottom of the uprights, blocks J J being preferably interposed between the ends of the levers and the uprights to increase the working space of the gate between the latter. The levers H H are arranged one on each side the gate, and in rear of these levers is arranged a corresponding pair of swing arms, K K, having their lower ends working on a transverse pivot-bar, L, between'posts D D. Each lever H has an about centrallylocated lateral pin, M, from which extends a line, N, to the end of a weighted lever, O, pivoted at the top of the upright C. These weighted levers O O aid in lifting the jumping gate. i

P P are a pair of bars, having slots Q at their lower ends, which work 'on the pins M. The topends of these bars P P are pivoted to the ends of a cross-piece, R, to which latter, at about its center, is pivoted the end of an operating-lever, S, pivoted to the upright, and having a hand-rope, T, at its end. S is a like overlapping lever, which is pivoted to and over the inner end of lever S, and is likewise provided with a hand-rope, T. It will, therefore, be seen that by operating either of the levers S S the gate is drawn up over the center of gravity and falls on the other side. The

bars P P are each provided with a rearwardly-extending pin or arm, U, which engages a cross-pin, V, passing through two levers, W W.

These levers are pivoted at 7 one end to one of the rails, G, and at the other to the longitudinal latch-bar, which works in openings X Y, respectively, in the front and rear end pieces, F F.

The latch-post B is formed with a recess, Z, to receive the end of the latch-bar.

When the gate is closed, the latch engages the recess Z, and the bars P P rest on the pins M M, which pins will then be in the top of the slots Q Q. By operating either of levers S S the bars P P are drawn up, without lifting the gate, the length of their slots Q Q, which movement throws the levers W W back, by means of pins U U and cross-pin V, so as to draw the latch-bar out of recess Z. Then the gate is thrown over by further movement of levers S or S.

The device is quite simple, and is ready and convenient in operation.

I claim as my invention-- 1. The combination of the outwardly-inclined uprights O G, the rear auxiliary posts, D D, the gate having pivoted arms K K and levers H H, the latter provided with lateral pins M, the lines N N, extending from pins M M to the weighted levers O O, the bars P P, pivoted cross-piece R, operatinglever S pivoted to the latter, and operating-lever S,

gate, having the longitudinal sliding latch-bar,

the pivoted levers W W, carrying the cross-pin V, the levers H H, having lateral pins M M,

the bars P P, having slotted ends Q Q, and

rear pins or arms, U U, said bars being connected to the operatinglever and the latchpost, as set forth.

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

JESSE THOMPSON.
