RAILROAD GATE} Application 'filed iq'evember 'JJ8, 1-925.- Serial No. 69,419i

reference being had to the. accompanying drawings, and to letters or figures ot' reference marked thereon, which form a part oi this specification,

The invention has relation to means for operating railroad gates at crossings and other similar places, having for an object to provide improved means for automatically doing this work upon passage of the car or train in, eitherdirection and for automatically returning the gate to first or inoperative position.

The invention consists in the novel construction and combination of parts, as hereinafter set forth.

In the accompanying drawings illustrating the invention, Figure 1 is a plan View of the invention somewhat diagrammatic showing the gates as set to operative position and the car approaching a crossing; Figure 2 is a side view of the same; Figure 3 is a side viwe of the invention partly in section and parts broken away on a somewhat larger scale, parts being shown in adjusted positions in dotted lines, parts being in normal position in full lines; Figure l: is a detail plan view oi the latch to hold the gate set to operative position; Figure 5 is a detail view o't one of the drums showing the cables and Figure 6 a detail sectional view of the guideway wherein works the device actuated by the ramp upon the car or train.

In these drawings, the numeral 1 designates a railroad gate of any approved form, to the pivot 2 of which is fast a drum 3, whereon is wound in one direction a cable l, one end of which is extender downwardly at 5 around guide pulley 6, and horizontally extended at 7 along one side of the railroad track 8 a suflicient distance away from the crossing and having its termination attached to coiled spring 9, the other end of said s-ipring being connected to slide 10 having an upward projecting lug 11, adapted for engagement with the ramp of a locomotive, or

other: car, said slide working in guideway 12.

The other end of said cable 4 is extended downwardly at 13 around v guide pulley i l and thencehorizontally at 15 in a direction opposite to that of thesaid end portion 7 ot the cable, along the same side of the track as ondrportion 7 a suiiicient distance and .then around a: guide pulley 16 and extended rei-ersely at Hand havingits terminal connected to coiled-spring 18, the otherend ot' said. spring being connected to a slide 19, working in guideway 20 and having an upward projecting lug 21 adapted for operation by the ramp 22 of a locomotive or car.

Upon operation of the slide 19 by ramp 1 22, the movement of said slide in its guideway will extendthe spring 18 tov exert tension upon. the cable 15. and thereby rotate thedru n 3 andset" the ate from vertical to, horizontal JOSltlOIl where it is en a ed 7 c n. i

and yieldably held by spring latch 23, the slide at the end of its guideway moving latorally due to a lateral ofl set 20 of the latter and thus escaping from the said ramp, whereupon said slide will be reversely moved by its spring, to take up excess move- .ment thereof in escaping said ramp as stated.

The locomotive or car having passed the ".ng it is desired to return the gate to .,al position and to this end ramp 22 oil the locomotive engages the lug oi the other slide 10, thereby extending the coiled spring 9 and exerting tension upon the said end portion 7 (it thee-able to rotate said drum 3 and return the gate as stated with satlicient force to overcome the comparat velv slight re rsistancoot the spring latch '33, the lug ot the slide escaping from the ramp by lateral movement in a lateral extension 12 at said gnideway in the same way as before stated, and the spring 9 returning the slideautomatically to normal position, the tension upon the cable simultaneously returning the slide 19 to normal position. it will be noted that the norn'ial position of slide 19 is at one end of its guideway 20, and the normal position of the lOis at the other end of its guideway 12, and that in the operation of the slide 19 to set the gate to operative or horizontal position, the said slide 10 is moved to the other end of its guideway 12, preliminary to operation to set the gate to inoperative or vertical position. The coiled springs entill able tension to be exerted upon the cable in such a yielding manner as not to impose too much shock or strain upon the parts.

A duplicate set of devices is arranged upon the other side of the track in reversed relation for the purpose of operating the gate upon that side of the track, (the same numerals being employed for designating the parts) by a train or car traveling in the opposite direction, whereby the gate will be thrown by a train traveling in either direction, and in order that both gates shall be thrown to operative or inoperative posi-.

tion sinniltaneously, the two drums 3, which are located diagonally opposite each other, are connected by a cable 25, passing around guide pulleys 2(3 and so wound and directed as to cause the one drum to be operated or rotated when the other is rotated. It will be noted that the coiled springs also hold the cables taut at all times and yield in harmony.

I claim 1. Means for automatically operating railroad gates, including a drum upon the pivot of the gate and having a cable Wound thereon, a guideway spaced from said gate at one side thereof and having a. slide working therein, said slide having a spring con nection with one end portion of said cable and being operable by a ramp upon the car to tension said spring connection to thereafter set the gate to operative position, and a guideway spaced from said gate at the opposite side thereof and having a slide working therein, said slide having a spring connection with the other end portion of said cable and being operable by said ramp of the car to tension said spring and thereafter set the gate to inoperative position.

2. Means for automatically operating two laterally opposite railroad gates, including a drum upon the pivot of each gate and having a cable wound thereon, a. guideway for each gate spaced therefrom at one side thereof and having a slide working therein, said slide having a spring connection with one end portion of its related cable and being operable by a ramp upon the car to tension said spring connection to thereafter set both gates to operative position, and a gnideway for each gate at the opposite side thereof and having a slide working therein, said slide having aspring connection with the other end portion of the related cable and being operable by said ramp of the car to tension said spring connection and thereafter set both gates to inoperative position.

In testimony whereof I aiiix my signature.

CHARLES E. RICE.
