SPECIFICATION forming par Application filed May 13, 1880. (No model.)

the bar reaches its full height. Dhe movements of the gate-bars are controlled by the I vertical movements of the shoes d d, which 55 movements are produced as will hereinafter appear.

' he rods D I) arej within the standards E E, so as to move vertically, the said standards protecting the rods 6c from injury by pas g ve ides. Ilhe lower D are respectively conwhom it may concern: e it known that OH s YOUNG, of

fof Rhode Island, have in and useful Improvements in Railway-Gates, and I do hereby declare hat the following specification, taken in connection with the acconipanying drawings, forming a part of the same, is a full, clear, and exact description thereof.

My invention relates to a railw aygate which is composed of bars located respectively on each side of the thoroughfare, and which are s raised and lowof the said bars being aushed bv a passing train.

H, which is mountet o rk underthe cross In order that the mechanism thus far ded shouldit become l and fail to work, t e arm His loosely is connected to n heavy coiled spring,

ployed for securing the movements of the gate, 0 bars composing the and in mountin, e

that they are capasuch a manner mounted on 20 same in ble of a lateral swinging movement, whereby, f should they descend upon a vehicle passing said shaft by means of under them, the said vehicle could clear itself one end of which is sccurct o the arm heir proper positions. and the other t a collar, h, attached to the the proper position of till h passing e hub of said arm, as show: and its immediat 25 Referring to the gs, Figure 1 reprea 't ack supplied with *ig. 2 hows the same in side elevation. ig. 3 represents, in plan, the mechanism located beneath the road-bed at 30 the crossing. Fig. 4 shows, in elevation, one of the gate-bars and the standard to which it is pivoted; and Figs. 5, an l 7 show details of the parts.

he rails located upon the r t a s are located in a pit nd are suitably protecte .2 and 3, an arm,J,iss r its end, the said a1 oad-bed, the r02 A A are t 5 which is planked at the crossing in h usua F manner. BB are the two bars composing the 1 and 2 is a wire lope or chain, ,which ate, which bars are arranged one on each side tends along l e of the track, and is the track,and are tached to an ad ustable rod, 70, whic ro( ar of a bell crank lever fro of the thoroughfare crossing pivoted to sleeves c c,loosely moun 4o ards G O,

To one of its ends is oted a lever, said lever being connected with the othe of the bell-crank lev As hereinbefore se the gate-bars, and consequent opening closing of the thoroughfare, is intended accomplished by a passing train.

For t iis purpose the sleeves 00, which arm of a bell-crank lever, T, secured to are loosely mounted on the standards 0 (J, are 115 it ,as shown in Fi sland 3. When arranged to revolve on said standards and or t is depressed therefore, the arm a ow the gate-bars to swing in a orizontal JG l-crank lever T is laised, the shaft plane, the said bars beingretnrned to position e( toward the right and the gate-bars v means of weights Y, attached b r cords ct Into a horizontal positi n. passing-over )ulleys in the standardsy to arms me using the gate-bars and openin the c, secured to sair sleeves, as s lfare when the train is moving from ,an 7. g'ht, the lever U is p hown in Figs. 2, rovided, the said 1g pivoted to a block,

ers of the road-bed at any desired '"rom the crossing. This lever U is 125 s shown only on one side of the track,- but it is to be undera Wire rope, is connected stood that both sides of the track may be pro lcal arm of the bell-crank lever T, as vidcd with gates which will 1g. 1. When, therefore, the lever with and o ssed the shaft 'ill b both be connected peratcd by the to e rocked to- :ft and the ck-shaft as de 1 0 scribed.

ate-bars will be moved Although I have chosen to locate the levers cal position. N 011 the outside of l I not shown in the drawings, it is to employ tie track and to rollers attached to the tender to operate them, yet I am aware that the said levers and their blocks may be placed on the inside of the track, the rollers be dispensed with, and the said levers be arranged so as to be operated .by the flanges upon the car-wheels. If,

however, rollers are employed, I prefer that they be adjusted at unequal heights above the rails, in order that the movement of the levers shall be more gradual.

The inclined faces of the levers N 0 R U are in practice much longer and of less inclination than shown in the drawings, and, if desired, the said levers may be balanced. When the levers N O R U are to be depressed by rollers located on the tender, both sides of said tender may be supplied with rollers and arrangements be made for raising those on the side not to be used when the train is running in a certain direction.

Although I have shown the rods D D as located exteriorly to the standards (3 0, yet they may occupy the vertical axes of said standards and the standards E E be dispensed with.

If desired, in place of moving the gate-bars in a vertical plane, they may be arranged to swing in a horizontal plane by substituting raclcbars for the shoes d and employing the proper gears to move the gates horizontally.

In order to give warning to approaching travelers, a gong-bell maybe located at the crossing and be connected by suitable devices to the mechanism working the gates.

As far as practicable, allmechanism coming to the weather should be housed.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The combination, with one or more railway-gates located at a road-crossin g, and each composed of two swinging bars pivoted on opposite sides of the thoroughfare, of a pivoted lever, N or R, located beside the track and connected with said gate or gates by mechanism substantially as described, whereby the gate-bars are simultaneously moved to close the thoroughfare by an approaching train, substantially as set forth.

2.

8. The combination, with the sliding block M, P, R, or U, its pivoted lever having an inclined face, its connected bell-crank lever, and a wire rope or equivalent. connecting said mechanism with the shaft I of the spring W, whereby the pivoted lever is maintained in its proper elevated position, substantially as set forth.

J. The combination, with the sliding block M, P, R, or U, its pivoted lever having an inclined face, its connected bell-crank lever, and a wire rope or equivalent connecting said mechanism with the shaft 1, of a wire rope or equivalent connecting said block with some rigid object, substantially as and for the purposes specified.
