Application filed December 20, 1917. aerial Ito. 205,138.

To all whom it may concern:

Be it known that I, HULEN BRAZEAL, a citizen of the United States, residing at Harrison, in the county of Boone and State of Arkansas, have invented certain new and useful Improvements in Automatically-Operated FarmGates, is a specification.

This invention relates to farm gates and more particularly to vehicle actuated gates of this character.

The object of the invention is to provide a simply constructed, automatically opened and closed gate, the operating parts of which are amply protected to prevent rust and the consequent inoperativeness incident thereto.

Another object is to provide operating means for a gate of this character located entirely below the surface of the earth and having platforms for engagement by the wheels of the vehicle for opening and closin the gate.

- ith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without de arting from the spirit of the invention.

11 the accompanying drawings Figure 1 represents the rear end of a gate' and its supporting post with the latter shown broken out and the operating means of the gate shown in longitudinal section,

Fig. 2 is a front elevation of the gate with its actuating mechanism shown in trans verse section, and

Fig. 3 is a detail horizontal section taken on the line 3-43 of Fig. 1.

In the embodiment illustrated, a gate G of ordinary construction is shown having the usual front and rear uprights U and U", respectively, and which is mounted to swing between front and rear posts P and P.

' The rear upright U has a shaft 1' extended longitudinally therethrough and projected at its opposite ends'beyond the ends of said uprights. This shaft 1 is provided wlth reduced terminals 2 forming journals for the shaft and which are engaged with hearings in arms 3 and 4: which'extend laterally inof which the following to be engaged ward from the upper and lower ends of the rear post P. Another arm 5 extends lateral y from the lower end of shaft 1 and is provided at its terminal with an eye 6 for a purpose presently to be described.

The post P may be composed of any sultable material and is here shown c0mposed of wood with its lower end pointed and embedded in a concrete base B which has a well or socket 7 arranged in front of the post into which projects the lower arm 4 and the lower end of shaft 1 as is shown clearly in Figs. 1 and 2.

Extending laterally in opposite directions from the well or chamber 7 are two conduits 8 and 9, preferably composed of metal pipes although obviously they may be made of any other suitable material. These conduits 8 and 9 are arranged in longitudinal alinement and may be of any suitable or desired length according to the distance at WlllOll it is desired to position the elements by a vehicle for opening and closing the gate.

These conduits open at their outer ends into Wells or chambers 10 and 11 located on opposite sides of the gate and which are covered by depressible platforms 12 and 13. These platforms are hingedly connected at their inner ends to suitable supports 14 mounted within the wells 10 and 11 at their inner ends. As shown, the platforms are provided at their inner ends with depending apertured lugs 15 through which the hinged pintles 16 pass and connect forms to their supports. 7

These platforms 12 and 13 are provided at their free ends 'on their lower faces with eyes 17 with which are engaged links 18. These links 18 connect said platforms with one arm of hell crank levers 19 which are fulcrumed at 20 on the bottoms of the wells in which they are mounted as is shown. clearly in Fig. 1.

Rods 21 and 22 connect the free ends of the other arms of said bell crank with the eye 6 carried by the arm 5 of shaft 1 as is shown clearlyin Fig. 2

By so connecting these platforms with the axle or shaft 1 on which the gate is de. signed to swing, it will be obvious that when the platform 12 is depressed by the passage thereover of a vehicle wheel or by a person or animal stepping thereon, a pull will be exerted on rod 21 which will operate the plat- Mitt to swing the gate into open position and to raise platform 13. After the vehicle passes through the gate and the wheels thereof engage the platform 13, it will be lowered and thereby operate through rod 22 to return the gate to closed position.

It will also be understood that when a vehicle approaches the gate from the opposite side, the wheels thereof will depress platform 13 and through link 18, bell crank 19, and rod 22 connected therewith, will 0 en the gate G in a manner similar to that 1ust above described, and that the closing operation at the other side of the gate will be effected in the same manner by the depression of platform 12.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the'method of operation will be readily apparent to those skllled in the art to Whic the invention appertains and while I have described the principle of operation of the invention together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

An inspection of Fig. 1 will show that the conduits 8 and 9 and all the actuating parts for opening and closing the ate, except the platforms 12 and 13 will be posed underground and the platforms closing the wells Leaders 10 and 11 operate to protect the contents thtiregf thus performin' g a double function.

e am:-

In a gate of the class described, the com-- bination of a supporting ost, a chamber arranged in front of sa1 post at the base thereof, arms extending laterally from said post at its upper and lower ends, one of said arms projecting into said chamber, conduits leading from said chamber in opposite directions and in longitudinal alinement, wells arranged at the outer ends of said conduits and communicating therewith, closures for said wells, hinged at one end to the inner side walls of the wells at their upper ends, other ends of said closure bein adapted to swing downwardly into the we s, stops for limiting the downward movement of said closures, an arm extending laterally from the lower pintle of said gate, rods connected at one end with said arms and extending through said conduits into the wells, links depending from the free ends of said closures, and bell cranks fulcrumed in said well between the outer ends of said rods and said links and connected at their free ends with said rods and links whereby the depression of either closure operates to open the gate.

In testimony whereof I afiix my signature in presence of two witnesses.
