CATTLE-GUARD.

Specification of Letters Patent.

Application filed October 10, 1907.

1 atented Aug. 11, 1908.

Serial No. 396,835.

To allwhom it may concern:

Be it known that we, \VILLIs L. FLEWEL- 1.1.x and ROBERT W. Prr'rs, citizens of the United States, residing at Buffalo Ga in the county of Custer and State of South lDakota, have invented certain new and useful Imrovements in Cattle-Guards, of which the ollowing is a specification.

This invention relates to cattle guards, and has for its object to provide an improved structure of such guard for railways, and to provide an exceedingly simple and inexpensive guard capable of eilectlvely preventing cattle and other animals passing over it.

In the drawings forming a orti'on of this specification, and in which like umeralsof reference indicate similar parts in the several views, Figure 1 is a top plan view of a railway track showing the arrangement of our cattle guard at bot-h sides of a crossing, Fig. 2 is a section on the line 2-2 of Fig. 1, Fig. 3 is a sectional view on the line 33 of Fig. 1, Fig. 1 is a perspective view of one of the rollers, Fig. 5 is a perspective View of one of the bars composing the frame, Fig. 6 is a detail perspective view of one of the pins for the rollers.

Referring now to the drawings, there is shown a cattle guard which consists of a frame 10 which is arranged between the tracks A, of a railway B, and this guard further consists of the frames 11 and 12 respectively, which are arranged at the outer sides The frames 10 comprise a plurality of vertically extending bars 13 and 14 which are arranged longitudinally of the tracks A. The bars 13 are arranged adjacent the inner sides of the tracks A and the bars 14 are arranged between the bars 13 and at the center of the railway ties C, as shown, and at the outer ends of frames 11, and 12. Each of the bars 13 and 14 is provided with a vertically extending web portion 15, and at the lower ends, these bars are provided with laterally extending flanges 16. Vertically extending passages 17 are formed in the flanges 16 for the reception of fastening de vices 17 ,"and by means of these fastening devices, it will be seen that the guard may be securely held to the ties C.

In the web portions of each of the bars 13 and 14, there are shown horizontally extending passages 18, and arranged between the bars 13 and 14, there are shown a series of parallel spaced rollers 19 which extend I crosswise of the tracks A, and these rollers are provided with trunnions 20 which are arwhich are formed in the bars 13 and 14.- It will thus be seen that the rollers are free to revolve between the bars 13 and 14. Threaded passages 22 are formed in the rollers 19, and arranged in these passages there are shown the threaded ends 23 of pins 24, and these pins have their outer ends pointed as shown at 25.

The longitudinally extending bars 13 and 14 have their upper edges serrated as shown at 26, and these serrated edges thus provide upwardly extending spurs 27 which arearranged adjacent the ends of the rollers 19 and in line therewith, and the spurs 28 which lie between the spaced rollers. The upper edges of the spurs are beveled as shown at 29 to form a knife edge 30.

The frames 11 and 12 are similar to the frame 10, but consist of but two longitudinally extending bars 13 and 14 respectively, and these bars are identical with the bars, 13 and 14, and it is thought that a description thereof is unnecessar Rollers 19' are journaled between these ars in a manner similar to that shown in the frame 10.

From the construction described, it will be seen that the rollers 19 and 19' are both of equal length, and the bars which are used in the construction of the frame 10 being identical with those shown in the frames 11 and 12, it will be seen that the frames 10, 11 and 12 may be formed of the same material. It will further be seen, that the construction shown provides a strong and durable cattle guard which may be shipped with its parts in sections, and which may be easily and quickly set up at its place of use.

In use, it will be seen that if an attempt should be made by cattle or other animals to travel from the crossing to a point longitudinally of the tracks A, they would come in contact with the guards at either side of the crossing, and in the movement of the cattle or animals it will be seen that the rollers will revolve, and the pins which are carried thereby will inflict sul'hcient pain and prevent further travel of the anima s.

\Vhat is claimed is:

1. In a cattle guard the combination with longitudinally disposed parallel bars having base flanges and a plurality of vertically disposed spurs at-thelr upper edges, said bars UNITED STAWENT OFFICE. i

ranged in horizontally extending passages 2 l having alining passages, of rollers disposed between said bars, trunnions carried by said rollers and disposed in said passages, and re,

movable pins carried by saidmoll ers.

2. The combination with revolumfin'ced rollers having removable ins, and trunnions carried at the ends of sai rollers, of a, frame comprising longitiulinally disposed parallel bars having base flanges, said bars having alining )assages in which said trunnions are dispose sharpened s urs carried by said bars at their upper ec ges a'nd located between the roliers at their ends.

In testimony whereof we aflix onr signatures, in presenceof two witnesses.
