GATE.

PECIPICATION forming part of Letters Patent No. 329,308, dated October 27,1885.

Application filed May 12, 1885. Serial No.165,225.

To all whom it may concern.-

Be it known that I, HIRAM S. HARRIS, a citizen of the United States, residing at Millville, in the county of \Voodford and State of Kentucky, have invented certain new and useful Improvements in Gates, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in gates especially adapted to farms, and is designed to produce a gate so constructed that it may be opened without alighting, that it automatically latches and unlatches, and that it will permit the passage of small animals without being opened.

In describing the device, reference is had to the annexed drawings, showing in Figure l a perspective view of the device, in Fig. 2 a detail of the latch, and in Fig. 3 a detail of one of the sheave-rollers.

A double post, A, is placed on one side of a roadway, and an abutting post, B, on the other side. About the same distance away, and at the rear of the main post A, is a post, 0, braced by a strip, D, which extends from the said main post. At a proper distance on each side of the main post are posts E, connected to the said main post by bracing-rails F. \Vithin a slot, G, in each of the posts E is a large flanged roller or wheel, H, operated by a'handle, I. Between the two parts of the main post, and next to the ground, is a roller, K, having a central groove. In the road, about midway, is fixed a roller, L. The gate M rests with its lower rail on the rollers K and L, and is guided in a measure thereby. The rear is supported by a roller, N, which travels on a rod, 0, or similar guiding-support extending from the main post to the rear post, 0.

On'thc main post, near the top, are fric tion-rollers P, which bear against the sides of the upper portion of the gate, and thus keep it steady.

On each part of the main post, both front and rear, are sheave-rollers R, as shown in Fig. 3 in detail. These rollers rest laterally,

and have the casing extended more on the under side than on the upper, forming thereby a rest for the'wires, which pass from the (No model.)

large wheels or rollers H to the front and rear of the gate, respectively. The extended portion of the casing reaches the outer edge of the periphery of the roller, as shown in Fig. 3. Vere the lower side the same as the upper side, when the wire became slack from any cause, it would slip from the groove in said pulley or roller and easily jam between the edge of the roller and the casing. By the extension of the casing this accident is prevented, as the edge of the roller is not exposed. By turning the rollers H, to which the wires are attached,the gate may be opened or shut. \Vire is preferable for the connections to either chain or rope, as it will not stretch, rot, or jam. The abutting post B is recessed longitudinally and receives the end of the gate. Within the recess is a projecting piece or pin, S, normally resting with in the end of the gate between the rails when closed, which forms a support for the end of the gate when the said end is raised for the purpose of allowing small animals to pass through, the roller N operating in lieu of a hinge. The latch is composed of a springarm, T, secured at one end to one of the rails of the gate, and having its free end projecting through the end of the said gate, and there provided with a catch or enlargement, which engages under a pin or similar device within the slot in the post B. A bell-crank, U, straddles the spring-arm T, and is pivoted to the rail carrying the said arm, and is provided with a strap, V, which passes over the arm. The wires passing to the front of the gate pass into the opening through which the spring-arm projects, and are connected to the bell-crank,so that theimpulse to open the gate will depress the said spring-arm and disengage it from the post.

I claim- 1. In combination with asliding gate,drums journaled in side posts, wires passing therefrom to both front and rear of the gate, and a latch consisting of a spring-arm with an en largement at its free end, and a pivoted bellcrank lever straddling said arm and having a strap which engages over it, the whole combined and operating substantially as and for the purpose specified.

2. lhe combination, with a sliding gate, of rest on, substantially as and for the purpose drums journaled in side posts, wires passing specified. Iotherefrom to both the front and rear of the In testimony whereof I affix my signature gate, sheave-pulleys with the under sideof in presence of two witnesses.
