eAlLRoAn cAr'rLe-GUARD.

SPECIFICATION forming part of Letters Patent N o. 546,775, dated September 24, 1895. Application liled April 2, 1895. Serial No. 544,168. (No model.)

To all whom it may concern:

Be it known that I, EDWIN G. EMMERT, a citizen of the United States, residing at Sherdahl, in the county of Republic and State of Kansas, have invented certain new and useful Improvements in Railroad Cattle-Guards;

and I do 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The special object of the invention is to makea cattle-guard gate which may be automatically opened by each train as it appreaches.

Figure 1 of the drawings is a-plan and Fig. 2 a perspective view of my invention, showing it applied.

In the drawings, A A represent the rails of a railway, under and between which is secured the board or plate B, from which, at one corner, uprises a post C. To the latter is hinged a gate D, extending across the track to prevent stock from passing out of a fenced field.

E is a crank-shaft pivoted to turn in postbearings c c and connected by an eye e at its outer end with adouble hook F, the latter being connected with an eye-rod G, made fast tothe gate-stile ol. The gate is heldin position across the tracks by a coiled spring H, one of whose ends is secured to the gate-'stile d, while the other is coiled about the staple I, or any other suitable contrivance. When the force which opens the gate has ceased to operate, the tension of the spring will close it.

J is a pinion fast on the lower end of the crank-shaft E and meshing with a spur-wheel K, which turns on a pivot in the board or plate B. On this spur-wheel is a fixed arm It, which extends under the track A', and on this arm is middle-riveted a plate L, with a hole Z near each end. In each of the holes l is secured one end of a rod M, whose other end is pivoted to the lower end of a lever N, whose upper end is struck by the wheel of each car on that side of the tracks, so as to operate the train of mechanism described and open the gate. The latter is thus held open until all the train has passed, when the coil-spring reti-acts the gate into position across the track. I may support thc rod M in a pivoted hanger o, but, while preferable, that is not necessary.

I am aware that cam-blocks, vibrating carnlevers, springs, and chains over pulleys are not new in connection with hingedY railroadgates; but

What I claim as new is The combination of a post C, a gate D hinged thereto and extending across the track; a shaft E supported in bearings on the post which carries a pinion J and hasa crank-arm extending behind said post; an arm G secured to the gate-stile; a link F connecting arm G withthe crank-arm; a spurwheel K intermeshing with the pinion .I and having an arm which passes under and completely across the track, tread-levers N connected to said arm; and a retracting spring secured to the gate, all substantially as shown and described.

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

EDWIN G. EMMERT. Witnesses:

B. M. EMMERT, ROSE EMMERT.
