BENJAMIN I-IARTIVELL I-IESTER, OF MCALESTER, INDIAN TERRITORY.

GATE.

SPECIFICATION forming part of Letters Patent No. 612,039, dated October 11, 1898. Application filed October 26, 1897. Serial No. 656,443. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN I-IARTWELL HESTER, residing at McAlester, Choctaw Nation, Indian Territory, have; invented a new and useful Improvement in Gates, of which the followingis a full,clear, and exactdescription.

This invention is an improvement in gates, and has for an object to provide a simple construction by which the gate may be automatically operated by the party riding or driving toward and from such gate; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a perspective view of my gate. Fig. 2 is a front view of the gate, and Figs. 3 and tare detail views.

The gate A is suspended between the posts B by means of the stub-shafts C, which journal in the posts B, one of such shafts being provided with a drum D, supporting the Weight E, and which drumv is clutched to its shaft preferably by means of the pawl F, engaging at F with a notch or shoulder O on the shaft 0. This drum is operated by the weight E, whose suspending-cord E is connected with the drum, and the weight when run down is readjusted or wound by means of the tripping-levers G, which have crank-arms G and G the former being arranged for operation by the wheel of the vehicle and the latter being connected by cord or other connection G with the drum to turn the same properly to wind the weight up. Where desired,these tripping-levers G may be provided on opposite sides of the gate, so that the weight may be wound by the approaching and departing vehicle; but ordinarily it is only necessary to provide the lever Gon one side of the gate.

It will be noticed that the gate swings vertically between the posts B, and to stop it at different points I provide a detent, which consists in the construction shown of a springactuated bolt H, which is normally pressed upward in position to be engaged by projections on the gate and holds such gate from being turned by the stress of the weight E acting upon the drum, which is clutched to the shaft (3, as before described. In connection with this detent I provide tripping devices,

whereby it may be operated to release the gate, so that the latter maybe turned one step by the weight. These tripping devices may be the crank-levers I and I, connected with the bolt, as shown, and arranged for operation by the wheels of a vehicle, or they may be pull-rods J for manipulation by a horseback-rider, or they may be of other desired construction. This detent locks the gate from movement in one direction, and it is held from movement in the opposite direction byaswinginglatch K, which opens freely' toward the detent to permit the projections of the gate to swing to and against said detents, but is held from movement in the op I posite direction. This construction prevents the gate from being opened by the pressure of stock on either side.

WVhere a light weight is used, it is ordinarily sufficient to provide the projections II above and below the shaft 0 on the side bar of the gate, as the weight will turn the gate so slowly that both wheels will pass over the detent-tripping lever before the gate has swung to full open position; but when a heavy weight is employed the gate will be operated so quickly that intermediate projections H are necessary, and these I furnish when needed on a cross bar or arm H set at right angles to the side bar of the gate, as shown.

Now in operation when the gate is supplied with thefour stop projections if a vehicle approaches from one direction its front wheel will operate the lever I, release the detent momentarily, and the gate will swing one step, bringing the following projection H into contact with the detent, which will then be released by the hind wheel of the vehicle and the gate will be opened. These operations of the tripping-lever and the resulting opening of the gate will lower the weight E, which will be rewound by thepressure of the vehicle on the lever G, and such vehicle may pass through the gate. As it moves off from the gate its wheels by proper contact with the tripping-lever I will actuate the detentbolt twice, and the weight will tend to readjust the gate to its closed position. It should be understood that the gate is nicely balanced by the weights M, which may be metallic, as shown, or, where desired, ornamental boxes filled with stone may be employed. By thus balancing the gate I avoid the necessity of a very heavy weight E, as the gate swings easily, and the weight E is only required to overcome friction in turning the gate.

13y suspending the gate at both sides there is no danger of its sagging, and its motions from time to time prevent the accumulation below it of any obstructions.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination in a gate of the upright posts, the gate having at its sides uprights pivoted to said posts, means for turning the gate, a detent for controlling the movements of the gate and a series of projections on the gate arranged in a circle and adapted for successive engagement by the detent as the gate is moved a part of a revolution substantially as set forth.

2. The herein-described improvements in gates consisting of the gate proper provided with shafts, the posts in which said shafts are journaled, the detent-bolt arranged to control the movements of the gate, tripping devices for releasing said detent, a drum on one of the shafts of the gate, a pawl on said drum and engaging with said shaft, a weight for turning said drum and means for readjusting or winding said gate, substantially as described.

The combination of the upright posts, the gate having at its sides uprights and provided with horizontal shafts jonrnaled in the posts, the detent controlling the movements of the gate, the weight acting upon the gate to revolve the same, means for readjusting the weight independent of the movement of the gate, devices controlling the operation of said weight to turn the gate, and tripping mechanism for releasing said devices substantially as descrlbed.

4. The combination substantially as described of the upright posts or supports, the

suspended gate having horizontal pivots whereby it may swing in a vertical plane, a drum on one of its pivot-shafts, clutch devices for connecting the drum with the said shaft, the weight suspended from the drum, the devices for rewinding said weight, detent devices, and tripping devices for releasing the detent whereby to permit the operation of the gate by the weight substantially as described.

5. The gate substantially as described comprising the posts or supports, the gate having horizontal pivots in said posts or supports one of such pivots being a shaft fixed to the gate, a drum on said shaft, a clutch connection between the shaft and drum, a weight acting on the drum, a tripping-lever connected with the drum whereby to turn the same to wind up the weight, the detent and tripping devices by which to release the detent substantially as described.

6. The improvement herein described comprising the gate having horizontal pivots and provided at one side with an extension beyond said pivot in the plane of the gate and with opposite extensions at right angles to the plane of the gate, a detent engaging cooperating parts 011 the gate, the extension, and the arms, devices for releasing the detent, and means for revolving the gate when the detent is released.
