RAI LWAY-GATE.

SPECIFICATION forming part of Letters Patent No. 391,019, dated October 16, 1888.

(No model.)

" To all whom it may concern:

Be it known that I, JOHN H. CANDEE, residing at New Haven, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements in Railway- Gates; and Ido declare the followingto beafull, clear, and exact description of the same, reference being had to the accompanying drawings, which form a part of this specification.

[0 My invention relates to an improvement in railway-gates, the object being to provide, for the protection of railway crossings, gates adapted to be operated by the drivers of the locomotives passing over the track, combining simplicity of construction and reliability of operation, and constructed so as to be readily pushed open by hand.

Vith these ends in view my invention consists in railway-gates having certain details of construction and combinations of parts,as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of a pair of gates embodying my invention, and Fig. 2 is a view thereof in side elevation.

As herein shown, there are two gates, and being alike in construction, only one will be described. Each gate is provided with a horizontal gate-beam, A, swinging through an angle of about forty-five degrees, to which it is limited by the posts 13 and C. The inner end of the beam is attached by a pivot, D, to the lower end of an upright movable gatehead E, having its upper end adapted to play in a staple, F,applied to the workingface G of the gate-post H,which, as shown,isrhombicin transverse section. The lower end of the gate-head E is provided with a bifurcated o arm, I, carrying a roller, J, traveling on a ridge, K, running lengthwise of the upper face of a rocking carriage, L, forming a support for the gate-head, and pivoted midway of its length upon a block, M, offsetting from the said working-face of the post. A frame, N, secured to the ends of the carriage, passes through the arm I at a point above the roller carried thereby, whereby the gate-head and roller are held in their proper relations to the carriage. A stay-rod, 0, attached to the outer end of the swinging gate-beam A,is connected at its upper end to a bar, 1?, projecting from the working-face of the post at a right angle therewith,and arranged to slide in and out of a head, Q, attached to the top of the post,and having a set-screw, R, for holding the bar in any desired adjustment. The gate-beam isin its central position when midway between the two posts, 13 and C; or in other words, when it makes a right angle with the working-face of the gate-post. This being the case, and the bar 1? being located in line with the beam when the same is in its central position, it will be seen that as the beam swings away from such position the stay rod will pull 6 against the outer end of the beam, and so check or break its movement and prevent it from slamming, so to speak, against the posts B and C. By adjusting the bar P the checking action of the rod may be regulated as desired. A bell-crank lever, S, carrying the hammer ofa gong, T, is pivoted to the postH, so as to be operated in sounding the gong every time the gate-head is lifted, which is every time the gate-beam is swung open and closed. For the purpose of shifting the movable gate-head, the carriage is rocked on its center. This is done through the drivers of the locomotives as they pass over the track U.

One end of the frame M is attached by a short link, V, to the upper arm of a bell crank lever, \V, pivoted to the outer edge of the gatepost and having its lower arm connected by a rod, X, with a horizontal four-armed pivotal head, Y, located between the two gate-posts and connected with the lower arm of the corresponding lever of the opposite gate-post. This head is also connected by a long wire, Z,

to a gate-closing dog, A, located up the track in position to be engaged and operated by the drivers of the engines, and by a wire, B, to a corresponding gateclosing dog, C, located down the track. These dogs operate to shift the carriages of the two gates so as to swing the gate-beams closed,and are effectively actuated in only one direction, and that in approaching the gates. The opposite end of the frame M of the carriage is connected by a link, D,

to the upper arm of a bellcrank lever, E, pivoted to the inner edge of the gate-post and IOO having its lower arm connected by a wire, F,

to a dog, G, located between the posts, connected, also, to the corresponding lever of the opposite post, and arranged to be effectively operated in either direction by the drivers of the locomotives,so as to rock the carriages for shifting the gate-heads so as to effect the opening of the gates.

The gate-head works upon the flat outer face of the gate-post, which is set so that the gate-beam will be at a rightangle with such face when it is in the center of the arc in which it swings. This arrangement secures the freest action of the beam, which opens and closes under the action of gravity by changing the center of gravity in it by shifting the position of its inner end.

When the gates are closed, as shown by the drawings, the carriages are inclined outward and the lower ends of the gateheads moved outward. Then when the train passes them it trips the gate-opening dog,which is adapted to be effectively operated from either direction. The tripping of this dog operates to shift the carriages so as to incline them inward, and so throw the lower ends of the gate-heads inward. This shifts the center of gravity in the gate-beams and causes them to open and swing outward until they are stopped by the flying posts B. The gate-beams being now open, they .will be closed by the tripping of either of the gate-closing dogs, whereby the carriages are inclined outward again,with the effect of shifting the lower ends of the gateheads outward, and so again changing the center of gravity in the gate-beams, which at once leave the flying posts and swing back to the posts adjacent to the track.

Under my invention very little power is required for opening and closing the gate-beams; nor does the fact that the operating-dogs are sometimes struck quickly and at other times slowly, according as the speed of the engine may be fast or slow, interfere with the successful operation ofmy invention; It is also to be noted that the beams may be readily pushed open from the inside for escape in case of being caughtin between them. The apparatus is, moreover, simple and cheap of construction, easily put up and kept in repair, durable in use, and reliable and effective in action.

It is apparent that in carrying out my invention I may make some changes and alterations from the construction herein shown and described. I would therefore have it under stood that I do not limit myself to such con struction, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention,what I claim as new, and desire to secure by Letters Patent, is-
