Application tiled December 4, 1916. Serial No. 134,979.

To all 'whom t may concern:

Be it known that T, CLAUDE R. GREENE, a citizen Vof the United States, residing at Rosston, in the county of Harper and State of Oklahoma, have invented certain new and useful Improvements in Gates, of which the following is a specification.

This invention relates to cattle guards and has for its object the provision of a simple, inexpensive and positively operating mechanism whereby a barrier will ordinarily be provided across a railroad track to prevent animals straying along the track from a road intersected thereby, and also to provide means whereby the barrier will be yieldably supported so that upon the approach of a train it will be lowered to permit the passage of the train and will automatically return to its normal position after the train has passed. The invention seeks to provide mechanism which will accomplish the desired results and which will be arranged in such a manner that it will be protected against the action of the weather and, therefore, will not need frequent repairs and renewals.

The invention is'illustrated in the accompanying drawings, in which,

Figure 1 is a plan view Of my improved cattle guard showing the guard or barrier in its lowered position to permit the passage of a train;

Fig. 2 is a sectional view taken longitudinally of the track and between the rails showing the barrier elevated;

Fig. 3 is a view similar to Fig. 2 showing the operating mechanism on a larger scale;

Fig. 4 is a transverse section on the line 4 4 of Fig. 3;

Fig. 5 is a detail perspective view of a portion of the track.

The track 1 is of the usual construction and the guard, consisting of a rock shaft 2 and pickets 3 extending therefrom, is disposed transversely of the track in line with a fence 4. Between the rails and adjacent each rail, I provide the operating levers 5 which are pivoted at their outer ends to the respectively adjacent track rail and have their inner opposed ends pivoted, as shown at 6, to brackets 7, the lower ends of which are each pivoted to an oscillating arm 8 eX- tending from a rock shaft 9. The Vupper edges of the levers 5 are grooved, as shown at 10, to accommodate the flanges of the car wheels and the pivot pins or bolts 11, by which the outer ends of the levers are attached to the track rails, extend transversely through the levers, the webs of the rails and the fillers 11 disposed between the track and base of the rail and between the web of the rail and the levers, as clearly shown in Fig. 5, so that the levers will be held against lateral movement and strain upon the pivot pins or bolts will be minimized. The rock shafts 2 and 9 are journaled in blocks or bed plates 12 which are disposed below the track rails and which preferably extend between adjacent ties. The oscillatory arms 8 are constructed at their free ends with racks 13 engaging pinions 14 on the rock shaft 2 so that oscillation of the arms will effect rotary movement of the rock shaft 2 and the barrier. The levers 5 are normally held elevated at their meeting ends by springs 15 secured to adjacent ties or other fixed supports and eX- tending over the ties to bear against the under sides of some of the levers at the free ends thereof, as will be readily understood on reference to Figs. 2 and 3.

It is thought the operation will be readily understood from the foregoing description, taken in connection with the accompanying drawings. Normally, the operating levers 5 will lie with their inner ends above the track rails, as clearly shown in Figs. 2, 3 and 4. When a train approaches from either direction, the car wheels will ride upon the levers and will immediately depress the nner ends thereof so that the oscillatory arms 8 will swing downwardly. This downward movement of the oscillatory arms will at once act upon the pinions 14 to rotate the shaft 2 and cause the pickets 3 to swing downwardly below the surface of the track rails and the levers 5. This movement is against the tension of the springs 15 so that immediately after the train has passed, the springs will act upon the levers and lift them so that the parts will be returned to their normal positions with the barrier in the position shown in Fig. 2 so as to extend across the track and prevent animals straying along the same. llt will, of course, be understood that the operating levers are of such length that as a train is passing there will always be Car wheels upon the levers at one or the other side of the guard or barrier and, consequently, premature rising of the barrier vio tween the levers, it becomes immaterial whether the train approaches from one or the other direction, The operating levers extend over the' springs and house the same so that they will not quickly corrode through the action of the elements and will be protected against breakage by stones which might tend to lodge thereon. The device is composed of few parts and operates positively in both directions.

Having thus described the invention, what is claimed as new is: 4*In 'a railroad gate, the combination of bed vplates adapted to be disposed below the rails of a track, a rock shaft journaled in said bed plates, a barrier projecting from said rock shaft, pinions on said rock shaft, oscillatory arms each pivotally mounted at one end on a bed plate and provided at its free end with a segmental rack meshing with one of said pinions, track levers adapted to be pivoted at their cuter ends to the rails and disposed adj acent'the same and above therock shaft and oscillatory arms, the inner meeting ends of the levers being over the respective oscillatory arms, brackets connecting the meeting ends of said track levers with each other and depending therefrom to connect them with the respectively subjacent oscillatory arms, and yieldable means to hold the levers and the oscillatory arms normally raised.

In testimony whereof I aiiix my signature.
