FERNAND A. STIEVENARD, 0115 GRAND FORKS, BRITISH COLUMBIA, CANADA.

CATTLE-GUARD.

Application filed September 29, 1914.

To all whom it may concern:

Be it known that l, FERNAND A. STIEVEN- ARD, citizen of France, residing at Grand Forks, in the Province of British Columbia, Dominion of Canada, have invented certain new and useful Improvements in Cattle- Guards; 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.

My invention relates to new and useful improvements in cattle guards for railway tracks and has for its primary object to provide a guard that will when the cattle attempt to cross or walk down the track be operated automatically by the cattle engaging a certain part of the guard. so that a barrier is formed and the cattle prevented walking on the tracks.

Another object of importance is to provide a device of the character described which employs means whereby the barrier is caused to rise from down position quickly so as to frighten the cattle and cause them to move away from the track.

Another object is to' generally improve and simplify cattle guards of the character described so as to render them more practical, reliable and efficient in operation and inexpensive to manufacture and install.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claim.

With reference to the drawings wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a top plan view of my improved guard, Fig. 2 is a side elevation showing the guard in up position, Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 1 showing auxiliary guards on opposite sides of the rails as well as between the rails and the end of a fence, and Fig. 4: is an enlarged detail sectional view showing the sliding pivot arrangement for the guard.

Referring to the drawings by characters of reference, the numeral 1 designates the rails of a track and 2 the ties thereof. Pivoted between the rails 1 is a barrier or guard Specification of Letters Patent.

member 3 that consists of a plurality of spaced parallel strips 4 that have interposed at the pivoted ends of the barrier spacing blocks 5 that are secured to the strips 4. shaft or pivot rod 6 is extended through the blocks 5 and strips i and projected beyond the outermost strips 4. Carried on the outer ends of the rod or shaft 6 are enlarged slide blocks 7 that are pivotally arranged upon the shaft 6. The blocks 7 are slidably mounted within longitudinal slots formed in guide blocks 8 which are secured upon one of the ties 2 of the track and are mounted inside of the rails 1. It will thus be seen that the member 3 is slidably and pivotally mounted.

Pivotally mounted between the rails 1 is an operating element designated 9 as an entirety that consists of a plurality of spaced strips 10 with blocks 11 secured between the pivoted ends thereof. A foot plate 12 is secured upon the pivoted end of the operating element 9 upon the blocks 11 and is of sufficient width to insure the cattle stepping thereupon when the cattle attempt to walk upon. or cross the track. A pivot rod or shaft 13 is inserted transversely through the strips 10 of the element 9 at a point adjacent to the end to which the blocks 11 are secured but intermediate the ends of the strips and is pivotally journaled in upstanding bearings 14 carried by one of the adjacent ties 2. The other ends of the strips 10 composing the member 9 are disposed between the strips 1 and wear blocks 15.that are arranged between the strips i by means of a pivot rod 16 that is inserted transversely through the strips 4: and 10, also wear blocks 15 and has suitable nuts 1'? turned on its free end to prevent derangement thereof. The ends of the strips 10 are connected with the strips 1 at a point intermediate the ends of the strips 4 thus when the foot plate 12 is en gaged by the cattle and depressed the opposite end of the member 9 will be moved upwardly and pull the guard 3 into up position as shown in Fig. 2 thus preventing cattle passing by the guard and at the same time frightening the cattle so that they will run from the guard off of the track.

If desired, the guard may be placed on either side of the track as shown in Fig. 3 as well as in the middle.

With reference to the foregoing description and accompanying drawings, it will be readily seen that I have provided a cattle guard which Will prove eflicient in use and may be easily installed and manufactured.

In practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most eflicient andpractical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as set forth. 4

hat is claimed is A cattle guard consisting of a guard element to be pivoted adjacent to one of the cross ties of a railway track and being normally in down position, below the level of the top of the rails of the track, an operating member pivoted at one end to said guard element at a point intermediate the ends of said guard element, a pivot rod extending through the other end of said operating member, longitudinally slotted guide blocks adapted to be secured to an adjacent cross tie and slide blocks secured to the ends of said pivot rod and being slidably mounted within said guide blocks.

In testimony whereof I aiiix my signature in presence of two Witnesses.
