GATE.

SPECIFICATION forming part of Letters Patent No. 433,434., dated August 5, 1890. Application filed March 23, 1889- Serial No. 304,448- (No model.)

To aZZ whom, it may concern:

Be it known that I, FELIX J. BAXTER, a citizen of the United States, residing at Braxton Court-House, in the county of Braxton and State of est Virginia, have invented certain new and useful Improvements in Gates of which the following is a speeification.

This invention relates to new and useful improvements in automatic gates; and it has for its object to provide a gate of this character having a simple and effective construction and operation, possessing strength and durability, and comprising but a comparatively small number of parts, and consequently to reduce the cost of manufacture.

I11 the drawings, Figure 1 is a perspective view of my invention, one of the gates being open. Fig. 2 is atransverse vertical sectional View on the line m m, Fig. 1. Fig. 3 is a longitudinal vertical sectional view on the line My y,Fig. 1. Fig. 4 is a top or plan View, the

gates, uprights, and flooring being removed. Fig. 5 is a detail elevation of a modification. Fig. 6 is a bottom or inverted plan view of the stop-block.

Corresponding parts in the figures are denoted by the same letters of reference.

The gates and their supports and the base or box platform and its beams are preferably constructed of wood; but it is obviously apparent that other materials may be substituted therefor as may be desired.

Referring to the drawings, A designates a rectangular base platform or box of suitable size, which may be buried below or remain fixed above the surface of the ground. This platform consists of two side planks A, united to two end planks A all of which are arranged on edge, and also has two long planks A, arranged to lie flat and be secured to the bottom edges of the planks A and A A top covering or flooring A is fitted on the top edges of the planks A and A and within said flooring are provided corner aperturesa and side apertures a, the latterbein g intended for the lower ends of the pivot-bars of the gates. Extending transversely across the platform is a beam or plank B, whose ends pass through central mortises in the lower part of short side planks O 0', arranged edgewise. These planksO O are arranged inside of the side planks of the frame and parallel therewith, and are provided with horizontallydisposed pulleys 0, arranged on each side of the center about midway from the ends. The ends of said planks C C are secured to cross-planks 0 arranged edgewise and bolted or otherwise secured to the sides of the platform A. In the said planks 0 adjacent to each of the ends of planks O and O, openings I or slots 0 are out, and adjacent to each of said openings 0, extending from the inside planks (3 to the ends of the platform ata downward incline, are pairs of braces 0 forming inclined planes, for a purpose hereinafter described. At the side of said openings 0 are provided vertically-disposed pulleys 0 Over the plank B a beam D is mounted, whose ends project through mortises formed in the central lower part of the planksO and O, as will be clearly seen in Fig. 3. This beam D has two springs S secured thereto, which project downward and bear on the plank B. The length of said beam is less than the width of the platform, to allow the same to have free vertical movement. The ends of the beam are formed with recesses 61, which engage with vertical guides or rods d, secured against the side planks A of the platform. The beam D is provided between the planks C and O with rollers to, which are mounted in a horizontal position and project above the surface of said beam.

Over the beam D, resting on rollers w and parallel with the sides of the platform, are two longitudinally-disposed bars E, which are shorter than the inside space of the said platform, and on the ends thereof above the inclined braces 0 hereinbefore referred to, are fastened blocks or keys e, rising above the top or flooring A and projecting through the apertures 0: therein. As the gates are open ed or closed the bars E shift backward and forward. The ends of the said bars E pass through the openings or slots 0 in the planks G which are sufficiently broad and deep enough to allow free longitudinal and vertical play therein ofthe ends of said bars.

Posts F extend upward from the center of the sides of the platform A and are joined together by a capbeam F, extending from one to the other. On the inner side of the said cap is a centrally-disposed locking plate or block'F provided at diametrically-opposite corners with recesses f, adapted to regudgeons f extending into and having bearing in cap-beam F. On the inner upright bars h gudgeons of similar character, but of less length than the gudgeons f are also mounted and adapted to engage apertures f in the locking-plate F and serve .in the capacity of bolts to secure the gates.

For operating each gate I have provided a cord or chain Z, which is secured to theoutside of the foot of the outer upright or pivot bar of its respective gate, from which point the ends of the cordare brought to the front, crossed, passed along the outer. side of the planks G orO, as the case may be, around the horizontal pulleys c, and brought back again, passing over the pulleys c and secured to the adjacent block or keys 6 on the respective barE. The gates being hung in reverse relation to each other, the operation of the cord mechanism is consequently reversed and the gates adapted to open in opposite directions.

The operation and advantages of my invention will be readily understood by those skilled in the art to which it appertains. Advancing toward the gate in either diree; tion, the operator depresses the key 2 at the right-hand side. This operation first lowers the beam D and consequently the gate, releasing the gudgeon h, and then moves the respective bar E toward the operator, causing the cord to draw upon the gate from the opposite side and throw it open in that direction. To close the opened gate, the key at the farther end of the bar E previously acted upon is depressed, drawing upon the cord in a contrary direction, and consequently imparting a reverse movement to the gate. Previous to the closing of the gate, however, the beam D is depressed by the operation of the bar E, permitting the gudgeon 7b to pass under the locking-plate F and when-the pressure upon the key is released the gudgeon h enters the aperture therefor in the locking-plate.

For retaining a gate against closing until the proper key is depressed I employ the construction illustrated in Fig. 1. It consists of two uprights S S, provided at the diametrically-opposite corners of the platform, toward which the gates are adapted to turn, connected with the ends of the cap-beam F by horizontally-disposed planks or bars S S provided at their farther ends, upon the under sides, with apertures s 3, adapted to -receivethe gudgeonsh'. The operation in connection with this eontrivance will be obvious. The gate during the swinging movement being at a lower plane than normally, it passes under the adjacent plank S and when pressure is removed from the-key e just operated upon the gudgeon h enters the aperture .9 and holds the gate open until properly closed.

If it is desired that the gates shall be low and without a cap overhead, the beam D is provided with under hinged sections d the springs S being interposed between the beam and hinged sections, as shown in Fig. 5. The

beam D is provided with upwardly-projecting pins that are adapted topass up into the inner upright bar of each of the gates to lock them, in lieu of the gudgeons h.

Having thus described my invention, what I claim as new isnected with and adapted to be turned'by the latter, substantially as deseribedn 2. In a gate of the character herein set forth, the combination of the platform, the frame-planks, the central sprmg-actuated beam, the bars with keys, inclined ways for the latter, the cords, and the gates, substantially as described.

3. In a gate of the character herein set forth, the combination of the platform, the.

thereof, the cross-bars having end keys mounted on said rollers, inclined ways for said keys, and the pulleys and cords, substan tially as described.

5. In a gate of the character herein set forth, the combination of the base-platform, the gates proper, the central spring-actuated beam having recesses in its ends, the guide IIO pins or rods with which said recesses engage,

the cross-bars having projecting keys, in clined ways upon which said keys slide, and the cords and pulleys, substantially asdescribed. V

6. The combination, with the gates provided with looking pins or gudgeons atthe upper ends thereof and adapted to engage apertures in a locking-plate, of a verticallyyielding bar forming the lower bearings for the gates, and means for depressing said bar, whereby the gates are lowered and the pins or gudgeons released from the locking-plate, substantially as set forth.

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