GATE.

SPECIFICATION forming part of Letters Patent No. 236,094, dated December 28, 1880,

Application led September 17,1880. (No model.)

To all whom t may concern Be it known that I, NATHAN ScARRIT'r, of Kansas City, in the county of Jackson and State of Missouri, have invented a new and Improved Gate, of which the following is a specification.

The object of this invention is to provide a gate that lnay be opened by an approaching vehicle or by a person on horseback without dismounting, and closed in the same manner.

The invention consists of a gate made in two like sections that are pivoted on horizontal axes, and of novel mechanical devices whereby the gate-sections are moved apart and closed in a vertical plane, all of which is hereinafter described.

Figure l is a partly-sectional front elevation of the gate closed, on line o@ fr, Fig.3. Fig.2 is a partly-sectional front elevation of the gate open, on line a: m, Fig. 3. Fig. 3 is a vertical sectional elevation of the gate on line yy, Fig. 2. Fig. 4 is an elevation oi' a modified mechanical device for operating the gate.

Similar letters of reference indicate corresponding parts.

1u the drawings, A A represent the two sections oi the gate, through each one of which runs a diagonal supporting-bar, A', to which the gate-section A is rmly framed. Both sections A A'turn simultaneously in vertical planes on axes B B, that pass transversely through the lower ends of said bars A, which extend below the gate-sections A at the outer corners thereof, beneath the level of the road C, the operating mechanisms ofthe gate being placed beneath the gate A, in avault, C', formed in the ground and lined with boxing C.- The axes B B extend across this boxin g O" and rest upon its sides. The diagonal supporting-bars Al extend downward about nine inches below the axes B, and have pivoted to their extremities, by pivots a a, suspension-rods D D, that carry a weight, E, which extends along the vault O from one to the other ot' the said rods D D, which weight E is so suspended that when the gate A is closed said weight E tends to pull it open, and when the gate A is open the weight E tends to close it, so that in any position the weight E almost countcrbalances the gate A, thus making it easy to operate.

At about eighteen inches from the left-hand The device is operated by two iexible cords or ropes, K, preferably of wire, one end of each being made fast to the right-hand end of the lever G, both of said ropes or cords K passing through an opening, b, in the top of the vault O', and over the pulleys d d, perpendicularly above the axle F. One of these ropes or cords K extends outtiiteen feet, or thereabout, along the roadway in one direction, and the other extends about the same distance in the opposite direction, the outer end of each being fastened to the lower end of a perpendicular lever, L, which is hinged at about its center to the top ot' a short post,M, set iirmly'in the ground. The upper end of each oi' these levers L is furnished with a liexible handle, N, which reaches over toward the middle of the road, and which handle N can consequently be easily grasped by a person in a carriage or on horseback. Each cord or rope K passes around pulley K at the foot of each post M. By pulling upon either of said handles N toward Athe middle of the road the lever G will be turned until its arms are brought into a vertical position, as shown in Fig. 2, and the gate-sections A A open, as shown in full lines in said Fig. 2. This is as far as the said gate can be opened by a slow steady pull; but by a quick short pull, and then an immediate release ot' the handle N, the gate-sections A A at this point will have acquired a momentum that will carry them over, as shown in dotted lines. In shutting the gate the double lever G is carried a littlebeyond a horizontal position, so that the end thereof to which the long har I is attached is a little below its axis F, and the other end thereof is a little above said axis F, to form a lock for the gate when closed.

In Fig. 4is shown a modiiication oi' this device, which is designed as a substitute for the ropes K and lever G, as shown in Fig. 4. The reciprocating double crank O is to be placed IOO where the lever and post L M are now situated. The cylindrical pulley or drum P and its horizontal connecting rod or tube P are t0 be placed in the vault C', andthe inner end of said rod or tube Il engages with the ends of the axle F. Tires or ropes Q connect the opposite arms ofthe lever Q', to which the crank O is attached, with opposite sides of the drum P. The object ot' this moditication is to open and close the gates A by operating the reciprocating crank O with the carriage-wheels.

It will be seen that the lever Q is covered by a cap or box, It, about four inches wide. From one of these caps It, on one side of the gate A, straight through to the cap R on the other side of gate A, a guide is designed to run, of the same Width as the cap R, to guide the carriage-wheel.

In driving through the gate A one waysay easterly-thewheelof the right side of the carriage runs on the south side of the caps It and guide,but in drivingwesterly through the gate A the left-hand Wheel runs on the north side of the same. The said cranks O are so arranged that when the Wheel, in approaching the gate A, strikes against and presses down the first cra-nl; 0 it meets, the said gate A will open, and at the same time the corresponding crank O on the opposite side of the gate A be raised, and on the same side ot' the intended guide, which latter cra-nk O Will be pressed down b v the same Wheel after the carriage passes through the gateway, and thereby the gate A will be closed.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. An improved gate constructed substantially as herein shown and described, consisting ot' sections A A, provided with diagonal supporting-bars A A', axes B B, suspensionrods l) D, weight E, axle F, carrying lever G, bars H I, cords K, and hinged lever L, as set forth.

2. The combination, with the pivoted gatesections A A, provided with diagonal supporting-bars A A', ot' the suspension-rods D D, Weight E, bars G H I, and axle F, arranged and operated substantially as herein shown and described.

NATHAN SCARRITT.
