CATTLE GUARD.

Application filed October 7,

Our invention relates to cattle guards for railways and its primary object is to provides guard of simple construct-ion which is easily applied to the ties of a railway track and which provides a substantial, du rable and efficient safeguard against cattle crossing or passing along the track.

A. guard made according to our invention may be applied at opposite sides of a highway andpositively prevent the escape of cattle from the fields and from the highway onto thertracks.

posed of six sections secured to the ties between and at opposite sides of the track and formedto provide two series of mclined surfaces between and. over the ties. These surfaces give no foothold to the cattle and the animals are in consequence prevented from crossing or passing along the track.

An embodiment of the invention thus briefly described,'is illustrated in the accompanying drawings in which like characters designate corresponding parts in all the views and in which Figure 1 represents a plan view of a portion of a railway track showing our improved cattle guard in its operative position Figure 2, a side elevation of the track looking in the direction of the arrow A in Figure 1, and p Figure 3, an enlarged transverse section of the track taken on the line 3--3, Figure 1.

The rails 5 0f the track are laid as usual on ties 6, spaced the required distance apart. At the portion of the track at which the cattle guai is applied, two ties 7 alternate with the other are reduced in height and fastened upon these lower ties are chairs 8 for the rails.

The chairs as best shown in Figure 3, have integral ridges 8 for the abutment of the outer flanges of the rails, and they are provided with clamp plates 9 that engage the inner flanges of therails. The plates are held in lace and are drawn downwardly to clamplngly engage the flanges of the ties, by bolts 10.

The chairs having bottom flanges that are apertured to receive the bolts or spikes 12 by which the chairs are fastenedto the ties and their sides slant u wardly to increase their rigidit and sta ility in use.

The cattle guar in its preferred form,

1927. "Serial No. 224,618. a

comprises two series of sections 13 and 14 of uniform length, placed one behind the other along the track. The sections of each series consist of plates made of steelor other suit able metal bent at their ends to provide oppositely projecting parallel flanges 15.

The flanges are bent at an acute angle to the body" portions of the plate so that when r the flanges are fastened in engage ment with the upright sides of two of the railway ties their body portions will extend s slantingly with reference to the horizontal. The guard in its preferred form is com- In the construction shown in the drawings, the sections of the guard are fastened to alternate ties 6 of regular form and supported upon the low ties 7 between the others. The flanges of the sections engage corresponding sides of the ties to which they are fastened by bolts 16, so that the sections at their uppermost ends extend across the ties. The two series of sections are placed successively with their adjacent flanges fastened one above another upon the same face of the same tie.

The sections of the series are arranged between and at opposite sides of the rails of the railway track in parallel relation to each other, the middle section 13 being of a width corresponding to the distance between the rails and the outer sections 14 being narrower so as to cover the end portions of the ties outside the rails.

It will be apparent that the arrangement of sloping plates between and over the ties shown in the drawings and hereinabove described provides an efficient, practical and very simple guard to prevent cattle from crossing or passing along a railroad track.

Having thus described our invention, what we claim and desire to secure by Letters Patent is 1- 1. The combination with a railway track having alternate ties of reduced height, of a cattle guard comprising aplate slanting between alternate ties of regular height and across the tie of reduced height.

2. The combination with a railway track having alternate ties of reduced height, of a cattle guard comprising a plate slanting between alternate ties of regular height and supported on the tie of reduced height.

3. The combination with a railway track having alternate ties of reduced height, of a cattle guard comprising a plate slanting between alternate ties of regular height and across the tie of reduced height, and chairs on the intermediate tie, supporting the rails of the track.

4. The combination with a railway track having alternate ties of reduced height, of a cattle guard comprising a plate slanting between alternate ties of regular height and across the tie of reduced height, and chairs on the intermediate tie, supporting the rails of the track, each chair having a ridge for abutment of a flange of the rail, and a clamp plate engaging the opposite flange of the rail.

5. The combination with a railway track, of a plate having its ends bent oppositely and at acute angles to provide flanges for its connection to ties of a railway track, the flanges engaging corresponding sides of two ties whereby the plate extends slantingly from one of the ties to and over the other tie.

6. A cattle guard comprising in combination with a railway track of standard construction, a flanged plate slanting from a face of a tie of the track across two following ties, the plate having its flanges fastened upon corresponding faces of the outer ties and the intermediate tie being reduced in height and providing a support for the plate, and chairs on the intermediate tie, supporting the rails of the track above the same.

7. A cattle guard comprising in combina tion with a railway track of standard construction two sections following one another in unbroken succession, each section comprising a flanged plate slanting from a face of a tie of the track across two following ties, the plate having its flanges fastened upon corresponding faces of the outer ties,

and the intermediate tie being reduced in height and providing a support for the plate, and the adjacent ends of the plates of the two sections being fastened upon the same'face of the same tie, and chairs on the intermediate ties of the sections, supporting the rails of the track above the same.

In testimony whereof we have afiixed our signatures.
