RAILWAY-CROSSING GATE.

Specification of Letters Patent.

Patented Aug. 19, 1919.

Application filed December 6, 1918. Serial No. 265,548.

To all whom it may concern:

Be it known that 1, JOHN SUTCLIFFE, a citizen of Canada, residing at Riondel, in the Province of British Columbia and Dominion of Canada, have invented new and useful Improvements in Railway-Crossing Gates, of which the following is a specification.

This invention relates to gates especially adapted to be used at railway crossings and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a gate of this character which is of a simple and durable construction and which is actuated by mechanism on a train passing the crossing at which the gate is arranged to first swing the gate from its position transversely of the track to a position transversely of the highway crossing and thereafter, after passing the highway crossing, to swing the same to leave the crossing unobstructed.

l/Vith the above object in view the gate structure comprises panels hingedly mounted at the side of the track rails and adjacent the side edges of the roadway with springs for normally holding the panels transversely across the track rails. A tower may be positioned at any desired distance from the railway crossing and a bell crank lever is pivoted in the tower and is operatively connected by means of cables with the gate panels whereby the panels may be swung from positions across the track rails to positions across the roadway. Guide bars are located between the track rails and blocks are slidably mounted on the said guide bars. Cables are connected with the blocks and with the first mentioned cables and the said blocks may be encountered by the pilot of an approaching engine whereby the blocks are moved and the cables are manipulated and the gate panels swung as hereinbefore described.

In the accompanying drawings Figure 1 is a partial plan view of the device showing the arrangement of the gates at the crossing.

Fig. 2 is a plan View of the remainder of the construction.

Fig. 3 is a view showing the position of the bell crank lever when the gates are in one position.

Fig. 4 1s a similar view showing the position of the bell crank lever when the gates are in another position.

Fig. 5 is a side elevation, partly in section showing one of the slidable blocks in one position on the rods on which the said block is mounted. I

Fig. 6 is a sectional view through the device disclosed in Fig. 5, and looking toward the block.

As illustrated in the accompanying drawing the track rails 1 are arranged in a usual manner and the crossing 2 is disposed transversely of the track rails. Panels 3 are hingedly mounted adjacent the track rails 1 and the side edges of the crossing 2 and springs 4 are connected with thepanels at one end and fixed points 5 at their opposite ends and are under tension with a tendency to normally hold the panels 3 transversely across the track rails 1.

Cables 6 are connected with the panels 3 and are trained around pulleys 7, S and 9 and are connected with a cable 10. It is apparent that by drawing on the cable 10 the cables 6 will be moved longitudinally whereby the panels 3 will be swung from positions across the track rails 1 to positions across the roadway 2.

A bell crank lever 11 is pivoted at a point remote from the crossinn- 2 and is preferably located between the sets of track rails 1. One end of the cable 10 is connected with the bell crank lever 11. The bell crank lever 11 is swung by mechanism on a passing train engaging with a slidable contact member, as will presently be described, and the swinging of the lever causes the cable 12 to be moved longitudinally.

To the second end of the bell crank lever 11 are secured cables 12 which are trained around pulleys 13 and which extend longitudinally between the sets of track rails 1, the said cables being also trained around a pulley 14 located centrally between the track rails.

Spaced rods 15 are located between the track rails 1 and extend parallel with each other. The ends of the rods 15 are secured to the ties of the track by means of plates 16. The rods 15 are provided at their ends with inclined portions 17. Blocks 18 are slidably mounted upon the rods 15 and may move along the inclined portions thereof.

Cables 19 are connected at one end with the blocks 18 and are trained around the pulleys 20 and connected with one of the cables 12. Cables 21 are connected at one end with the other cables 12 and are trained around the pulleys 22 and connected at their other ends with springs 23 which in turn are connected with the blocks 18.

The parts are so arranged that when the bell crank leverll is moved so that the gate panels are swung to positions across the roadways 2 the blocks 18 are below the path of movement of the pilot of a locomotive which may travel upon the track rails 1. However should the gate panels loe in a position across the track rails 1 the blocks 18 willbe at the intermediate elevated portions of the rods 15 consequently an approaching pilot will strike one of the blocks and move the same along the rods whereby the gate panelswill b automatically swung from positions across the track rails to position across the roadway. Therefore the the end of its path of movement in either direction. However, when the bell crank lever is moved initially the tension of the spring 1 will come into play and unless otherwise influenced the gate panels 3 will be swung to positions transversely of the track rails 1. 7

Having described the invention what is claimed is l. A crossing gate comprising panels hingedly mounted, springs for normally holding the panels at predetermined positions, a bell crank lever p-ivotally mounted, means operatively connecting the bell crank lever with the panels, bars mounted at fixed positions and having inclined ends, a block slidably mounted on the bars and means operatively connecting the block with the first mentioned means.

2. A cross gate comprising hingedly mounted panels, springs for holding the panels at predetermined positions, a bell crank lever pivotally mounted, means operatively connecting the bell crank lever with the panels, rods mounted upon fixed supports and having inclined end portions, a block slidably mounted on the rods and adapted to move upon the inclined portions thereof, a cable connecting the block with the first mentioned means, a second cable connected with the first mentioned means and a spring connecting the second mentioned cable with the block.

In testimony whereof I aflix my signature.

- JOHN SUTCLIFFE.
