AUTOMATIC RAILWAY STOCK-GATE.

To all whom it may concern:

Be it known that I, IVILLIE 'W. NELSON, a citizen of the United States, residing at Monticello, in the county of Lawrence, State of Mississippi, have invented certain new and useful Improvements in Automatic Railway Stock-Gates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in railway gates and particularly to stock gates for railways.

One object of the present invention is to prov de a novel and improved means for opening the gates actuated by a passing train.

Another object it to provide novel and improved means for mounting the gates whereby they will be more quickly and positively moved into open and closed positions.

Another object is to provide novel and eflicient means for automatically closing the gates after the train has passed, and also to prevent injury thereto and noise thereby.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a transverse sectional view of a railway showing my improved gates thereon and in closed position.

Fig. 2 is a top plan view of the same.

Fig. 3 is an enlarged vertical sectional view taken on the line 33 of Fig. 1.

Fig. 4 is an enlarged vertical sectional view taken on the line H of Fig. 1.

Fig. 5 is a vertical sectional view taken on the line 55 of Fig. 1.

Fig. 6 is an enlarged vertical transverse sectional view taken on the line 6-6 of Fig. 2.

Fig. 7 is a longitudinal sectional view taken on the line 7-7 of Fig. 2.

Fig. 8 is an enlarged vertical sectional view taken on the line 88 of Fig. 7.

Referring particularly to the accompanying drawings, 10 represents the rails and 11 the ties of a railway. Mounted in suitable brackets 12 carried by the ties, and extending longitudinally in close proximity to one of the rails, is a shaft 13, the intermediate portion of which is formed with a crank 14. The opposite ends of the shaft are turned at Specification of Letters Patent.

right angles to the shaft to form crank arms 15. In one of the ties is countersunk a socket member 16, and movable vertically in this socket is a pin 17 the upper end of which is pivotally connected to the intermediate portion of a rail 18 which is supported at one side of the rail 10 in position to be engaged and depressed by the treads of the car wheels. Encircling the pin 17 and disposed between the rail 18 and the upper surface of the tie is a coil spring 19 which holds the rail 18 in normal elevated position. At suit able distances from the pin 17, the rail 18 has pivotally connected to its lower face, the depending links 20, said links being pivotally connected to the crank arms 15, before-mentioned.

In a line transversely of the railway, and on opposite sides of the railway, are disposed the fence sections 21, each of which carries the U-shaped brackets 22, supporting the grooved rollers 23. Disposed to roll in the upper portion of the grooves of the lower rollers is a ribbed strip 24, and rolling in the lower portions of the grooves of the upper rollers is a second similar strip 25. These strips are suitably connected to the upper and lower portions of the gates 26,,whereby said gates will slide easily and positively toward and away from the railway. Mounted adjacent each of the fence sections, and approximately midway of the lengths thereof, is a base member 27 on which is supported a crank shaft 28, by means of the bearing blocks 29 carried by the base. One end of this shaft is provided with a crank arm 30 which is pivotally connected to the adjacent gate by means of a link 31. On the other end of the shaft, which projects beyond the outer bearing, there is disposed a coil spring 32, one end being secured to the shaft and the other end to the bearing. This spring serves to normally move and yieldably hold the shaft in its normal position, or in the closed position of the gates. Connecting the crank portion 28 of the shaft 28 with the crank 14 is a link 33, whereby when the rail 18 is depressed the shaft 13 will be rocked and communicate its movement, by means of the link 33, to the shaft 28, and cause the sliding movement of the gate into open position. After the train has passed the gates, the springs 19 and 32 reset the parts to normal position, including the closing of the gates.

On the opposite side of the railway, to that just described, the parts are duplicated,

but it will be noted that the crank of the shaft 28 normally extends downwardly while the other crank eXt'en'ds upwardly. By this arrangement the gates will be moved in opposite directions through single simple movement of the connecting rod 3 1 which extends between and connects said cranks. This rod extends below the rails and between the ties.

Connected to the free vertical end of one of the gates, by means of the springs 35', is a buffer strip 36, which is arranged to engage with the corresponding end of the other gate 1 to relieve the gates of the shock and noise when closing.

\Vhat is claimed is: A railway stock gate including a pair of gates slidable toward and away from each other and across a railway, crank shafts mounted on opposite sides of the railway, springs carried by the shafts for holding eora-ea them yieldably in normal position and serv' ing to close the gate, a rod slidable transversely beneath the railway, links pivotally connected to the ends of the rod and to the respective crank shafts, a depressible member located adjacent one of the rails of the railway, a crank shaft mounted adjacent the depressible member and in parallel relation thereto, links connected to the depressiblc member and the last-named crank shaft and a link" connected to the lastenamed crank shaft and to one of the first-named crank Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, .D.
