7 Application filed April 30, 1919. s rial No. 293,74 1,

To all whom it may concern; v a v Be it known that I, ANTHONY Grnrores a citizen of Russia, residing at Worcester, county of WVorcester, and State of Massachusetts, have invented certain new and useful Improvements in Railroad-Gates, of which the following is a specification.

This invention relates to improvements 1n device for automatically operating the gates at railway and roadway crossings.

The principal object of the invention is to provide means, actuated by an approaching car or train, which will cause the gates to be lowered preventing the passing of teams, animals, or the like along the roadway crossing the tracks.

A further object is to provide means whereby the gates are automatically raised after the train has passed the crossing.

These and other like objects are attained by the novel construction and combination of parts hereinafter described, and shown in the accompanying drawings, forming a material part of this disclosure, and in which Figure 1 is a partial fragmentary side elevational and partial vertical sectional view, showing a conventional type of railroad and street crossing construction, indicating the application of the invention.

Fig. 2 is a transverse sectional view taken on line 22 of Fig. 1, and

Fig. 3 is a diagrammatic plan view showing the arrangements of operable parts, the cables indicated by the full lines acting to lower the gate, while the cables indicated by the broken lines serve to raise the same after the passage of the train.

Referring to the drawings, the numerals l0 and 10" indicate pairs of rails as used for a double track railway, the same resting upon ties or sleepers 11, while the roadway is designated by the numeral 12, the same being shown substantially level with the top of the running rails, at points between the railway tracks.

In Fig. 1 the element 15 designates a portion of a car or locomotive to which is attached a support spring 16, engaged at its lower end with a skid 17, having upturned ends 18.

At fixed intervals adjacent to the crossings, are secured in the roadbed, casings 19 in which are pivoted levers, respectively 20' @119 272, v e f rm eing in length upon" the pin 21', while the lever '22 is pivoted at its end upon the pin 23,

pivoted m dway J ournaled in the upper end of the levers 20 and 22, are rollers 24 with which the train carried skids 17 makes contact, thereby depressing the levers in an obvious manner.

Arranged at the intersecting corners of the railway and roadway, are posts 25, carrying pivots 26 on which are mounted the gate elements 28, the same being arranged in palrs as is usual, and of such length, that when in a downward position, as to prevent passage across the railroad tracks.

The rear ends 29 of the gate elements have engaged with them short flexible cables 30, connectmg with counterweights 31, movable freely in vertical casings 32, attached to the rear of the posts 25, and secured to the lower ends of the counterweights 31, are other cables 33, passing below guide pulleys 34, the cables 33 being joined together, as at 35, and continuing as at 36.

Engaged with the gate elements 28, upon the opposite side of the pivots 26, are other cables 40, running under guide pulleys 41, the cables connected together and passing over other pulleys 42, and under guide pulleys 43, rotatably mounted in the casings 19 and connecting with the lower end of the lever 20. 4

In operation, an approaching train or car, as indicated by the numeral 15, causes its attached skid 17 to make contact with the roller 24, tipping the lever 20 and exerting a pull upon the cable 40, which, being guided over the several pulleys, causes the gates 28 to swing downwardly, as indicated in the full line in Fig. 1. The train continuing, causes the skid to make contact with the pulleys set in the ends of the lever 20, there by exerting a pull upon the cables 36, which, passing freely over the several guide pulleys, exerts a pull upon the counterweight and cable connecting therewith, to the outer end of the gate elements, causing the gates to be raised, as shown in the broken line in Fig. 1, and as the same arrangement operates in a reverse manner upon the adjacent track it will be seen that a train moving in a forward direction upon either track 'will automatically lower and raise the gates at-its passage over the crossing.

Having thus described my invention What I clalin as new and desire vto secure by Letters Patent, is

A railroad-gate operating mechanism of the character described comprising casings secured in the roadbed adjacent to a crossing, a lever pivoted at its end in one of said casings and a second lever pivoted at its center Within the other casing, rollers at 10 the upper ends of said levers adapted to be 7 Copies of this patent may be obtained for depressed by a passing train, cables guided over pulleys and. secured With one end to the gate intermediate its ends and to one of said levers, and cables secured to the Weighted ends of said gate and to the other of said levers, substantially as described, and for the purpose set forth.

In testimony whereof I have affixed my signature.

ANTHONY GRIGAS.
