PECIFIOATION forming part of Letters :Patent No. 542,123, dated July 2, 1895.

Application filed February 4, 189 5,

. To'all whom it may concern.-

Be it known that I, JULES WEILL, a citizen of the United States, residing at Chicago, in

. the countyof Cook and State of Illinois, have invented certain new and useful Improvements in Automatic Railway-Gates; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to that type of gates for railway-crossings in which the gates are raised and lowered or opened and closed in an. automatic manner by a train of cars passing in either direction; and the objects of the present improvement are to provide a simple and efficient mechanism for such use which is adapted to operate in an automatic manner either a single gate-or a series of gates, and is capable of operation by a railway-train passing in either direction along the railwaytracks. I attain such objects by the construction and arrangement of parts illustrated in the accompanyingdrawings, inwhich .Figure 1 is a. vertical sectional elevation illustrating my present invention; Fig. 2, a plan view of the same with portions broken away to illustrate the operative underground connections of the present invention; Fig. 3, an enlarged detail transverse section of one of the longitudinal sliding heads or trucks by which the gate mechanism is actuated.

Similar numerals of reference indicate like parts in the different views.

As represented in the drawings, the gates proper will each consist of a long bar 1, of wood or other suitable material, pivoted in a suitable standard 2 at the side or sides of the wagon-roadway and adapted when lowered to bar or close said wagon-roadway.

3 is the rope or flexible connection by which gate-bar l is raised or lowered. This rope or flexible connection 3 passes over a sheave or I pulley 4 on the carrying-shaft of the alarmbells 6 at the upper end of an upright 5, that may form a part of the gatebar standard 2, if desired, and from thence down to an underground sheave or pulley 7, as shown in Figs. 1 and 2. From the pulley 7 the flexible connection or rope 3 passes along in a horizontal direction to and around a pulley or sheave 8, to and around a pulley or sheave 9, and then Serial No. 537,293- (No model.)

downwardly, to be connected to an operatingweight 10 or other equivalent means by which a pull can be effected upon the rope or flexible connection 3-such, for instance, as a spring or air cylinder and piston. This arrangement of ating or operating weight 10, which preferably has a central arrangement, as shown in Fig. 1, with relation to the gates andtracks.

11 isa sliding block or truck adapted to move in a guideway 12, preferably by means of the upper and lower bearing- wheels 13 and 14. This truck or block 11 is attached to one end of a flexible connection or rope 15 that passes around a pulley 16, then in a return horizontaldirection to a sheave or pulley 17, andthen downward to be connected to the common operati'ngweight 10.

- The guideway 12 is arranged between the railway-tracks, as shown, and extends parallel therewith, its upper end being slotted so as to form alongitudinally-extending way 18 v for the movement of the trigger or catch 19 of the sliding block or truck ll. This is engaged by any suitable part or projection on the railway-train,so as to be carried along by the same as such train approaches the crossing, and in so doing to raise the operating-weight 10 and release the different gates 1, so that they will descend by gravity and close or bar the wagon-roadway, such gates being of an overbalanced or loaded nature for such purpose.

The trigger or catch 19 is pivoted in the sliding block or truck 11,'and is engaged at one side only by a stop-pin 20, so that it can only be engaged by the railway-train in passing toward the roadway or crossing, the construction being such that it wili be merely tilted down by the railway-train in passing in the opposite direction, to wit: in running away from the crossing, after which it will be returned to its usual upright position by its weighted lower end 21.

In order that the block or truck 11 may which case the length of'theguideway 12 and only be carried a specified distance along with the train, and that just sufficient to raise' the common operating-weight 10 to allow the crossinggates l to descend or close, the guideway 12 is formed with a downwardly deflected portion 22 down which the sliding truck or slide 11 moves, so as gradually and finally to remove the upper end of the trigger 19 out of the path of the projection or other part of the railway-train by which it had been previously engaged and carried along. Such arrangement of the guideway and truck or slide and its connections to the common weight 10 constitutes the automatically-operating portion of the apparatus, by which the railway-gates are lowered by an approaching train and raised by the departure of the same; and such automatic mechanism will be duplicated at each side of the crossing for each and every railway-track upon the railway road-bed; In the drawings I have illustrated a single railway-track, with a corresponding pair of such automatic mechanisms in proper position with relaiion to the wagon-roadway and the railway track.

The operation of my invention is as follows: An approaching train before reaching the crossing moves the sliding block or truck 11 to raise the common weightlO through the instrumentality of the flexible connection 15 and the sheaves or pulleys 16 and 17. The raising of the weight 10releases the different flexible connections 3, so that the railwaygates will be free to descend and bar or close the roadway-crossing. After the passage of the railway-train past the sliding block or truck 11, the weight 10 is released to draw said block or truck '11 back to its original o: sition, as well as to lift or open the gates. I

In practical use the automatically-operating mechanism of the crossing-gate, of which the sliding block or truck 11 constitutes the operating part, may be located at any required distance away from the roadway-crossing, in

the amount of vertical inovementof the operating-weight 10 will be correspondingly increased, with an increase in the distance of location away from the crossing, it being in all cases the intention that the railway-train shall reach the crossing during the time that elapses in the raising of the gates and the return of truck or slide to its original position, such return movement of the slide or truck being slow as compared with the speed of the train.

The raising of the gates may be made very tardy and ina controllable manner when desired by providing a retarding device, such, for instance, as the the ordinary dash-pot retarder used in steam-enginery and other wellknown branches ofthe mechanical arts; and where the apparatus is used on roads in which the trains are run at an excessive speed, elasqblock 11,;providedwith a pivoted trigger 19,

arranged in the path of the railway train, and a flexibleconnection 15, between such block 11, and weight 10, substantially as set forth.
