RAILWAY-GATE.

SPECIFICATION forming part of Letters Patent No. 351,128, dated October 19, 1886.

Application filed June 10, 1886. Serial No. 204,716. (Mullet) which form a part of this specification.

This invention relates to that class of railway-gates which stand across the track, and which are automatically lowered by an approaching train, and then automatically resume their normal elevated position.

More specifically, the gate in this invention is one of that class which has a cross-bar rotatively mounted beneath the rails, to which vertically-extending pickets are secured; and the bar is turned to lower the pickets by connection with rods which run parallel with and inside the rails, and are acted upon by the flanges of the car-wheels.

The invention consists in the construction and arrangement of the parts which co-operate to raise and lower the gates, as will be hereinalter set forth in connection with the description of theaccompanying drawings, in which Figure 1 is a plan view of a portion of a railway 1 track provided with the improve ments. Fig. 2 is a vertical cross-section in a plane indicated by the line 2 2 in Fig. 1, showing the gate raised. Fig. 3 is asimila-r section showing the gate lowered, and Fig. 4is a longitudinal section. in a plane indicated by the line 4 4. 1

A A are the track-rails, and B B the crossties. At the place where the gate is to be lo cated the track-bed between two ties is cut away and suitably boxed to admit the cross bar 0 of the gate to be placed beneath the rails. This bar is rotatively mounted in bearjug-pieces D D, secured to the cross-ties on either side of the track. To the bar 0 are secured the gate-pickets E E. The gatc'bar is normally held in proper position to cause the pickets to assume a vertical position by means of a strong spring, F, secured at one end, and

pressing at its free end upon a stop, c, carried by the gate-bar.

Between the rails A A is fixed a bracket, G,

to which is fulcrumed a lever, H, of the first 5 class. One end of this lever is connected to the bar 0 by means of an eye, 8, through which passes a circular arm fixed to the bar, which arm may be the same as the stop a, and

the other or inner end, in, of the lever, which 6 extends midway between the rails, is connected to the operating-rods I I. There are two of these operating-rods, one 011 each side ofthe gate. They are located between and adjacent to the rails, one being alongside of one rail 6 and the other alongside the other rail. Each of these rods has a horizontal portion, b,whieh is parallel with the rail, and located in a plane substantially that of the tread-surface of the rail. This portion 1) is of sufficient length to 70 ond horizontal portion, 9, of the rod I extends s just above the surface of the ties from the pivot (I nearly to the lever H. The end of this section 9, which is a continuation of the imaginary axis passing from pivot d to pivot f, is bent to constitute a crank, h, having a $5 crankpin, 1;, which extends through an aperture in the end in of lever H. The two rods I I are substantiallyalike. Only one, how ever, has the horizontal portion nan1ely,

the one toward which the gate turnsand 0 while one has a crank-pin, t, on the crank h, the crank h of the other rod has an elongated slot or eye, 0, which embraces the crank-pin.

The operation of the l'llGOllZtlllSlll is as follows: .WVhen a train approaches, the flange of 5:

the first wheel enters between the downwardly and inwardly curved end 0 of the rod I and the rail. On the further advance of the train the flange of the wheel encounters the body b of the rod I and moves it inward, the piv 10o ots d andf permitting the movement. This turning of the rod turns the cranks h h down- Near the gate the 75 ward, thus depressing the inner end, m, of le ver H, and consequently lifting the outer end thereof, which is connected with the gatebar. This upward movement of the outer end of the lever acting upon the arm a lifts the arm, and so turns the cross-bar on its axis, thus lowering the pickets out of the way of the train. The circular shape of the arm a permits the bar to turn under the action of the lever. The downward movement of the end n of the lever H turns the rod I on the other side of the gate inward away from its rail, and it is held in that position by the wheelflanges until the last car has passed. WVhen the last car has passed, the spring F restores the parts to their normal position.

The long section b of the rods I I may be supported by links H, pivoted to the crossties in line with the pivots d f.

I claim as my invention- 1. A railway-gate bar rotatively mounted crosswise of the railway-track and beneath the rails, means for holding the gate-bar normally in position to interpose the gate across the track, andalever pivoted between the rails and connected at one end to the gate-bar, in combination with operating-rods pivoted on either side of the gate within the rails, said rods having sections parallel with and adjacent to the rails, and in substantially the same plane as the tread-surface of the rails, and a crank on the end of each rod next the gate connected to the inner end of said lever, substantially as set forth.

2. A railway-gate bar rotatively mounted crosswise of the track and beneath the rails,-

and a curved arm, a, secured to said gate-bar in a plane at right angles to the bar, in combination with an operating-lever pivoted between the rails in a plane substantially parallel with the gatebar, said lever'having an eye which is engaged by said curved arm, substantially as set forth.

3. A railway-gate bar and an operating lever connected thereto at its outer end, said lever having an aperture in its inner end, in combination with two rods acted upon by the flanges of the carawheels, said rods having cranks, one of said cranks having a crank pin passing through said aperture in said le ver, and the other crank having an elongated slot which embraces said crank-pin, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

I JACOB J. BUYER.
