CATTLE-GUARD.

I @ZZ whom, t may concern:

Be it known that we, FRED OTTO RICHTER and GUsTAv ADODPII RICHTER, Citizens of the United States, residing at Buckholt's, inv the county of Milam and State of Texas, have invented a new and useful Cattle-Guard, of which the following is a specification.l

This invention relates to cattle-guards, and has for an object to provide a device of the class embodying new and improved features of reliability, utility, and efliciency. f

With these and other objects in view the present invention consists in thek combination Vand arrangement of parts, as will be hereinafter fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being underving the gears 18 18 vany approved number and stood that changes in the form, proportion,

size, and minor details may be made Without departing from the spirit or sacrificing any of the advantages of this invention.

In the drawings, Figure 1 is a perspective view of the improved cattle-guard with the gate raised by an animal shown thereon in dotted lines. Fig. 2 is a top plan view of the o erating mechanism with the platforms slilown in dottedy lines and the rails broken away. AFig.v 3 is a' transverse sectional view taken on line 3 3 of Fig. 2, showing the gate raised and in dotted lines the position of the parts with the gate depressed.

Like characters of reference indicate corre-y sponding drawings.

In its preferred embodiment the improved cat tle-guard forming the subject-matter of this application is carried upon a pair of beams 10, engaging stationary abutments 11 11, whichform cross-ties for the support of rails 12 12 and, With the cross-tie13, carpartsin all of the gures of the ried on the beams 10 10, support the rails in-f termediate the abutments. To, the beams adjacent their ends are secured cross-bars 14 and 15 and a third cross-bar 1 6,spaced from the bar 14. Between and to the cross-bars 14 and 15 are'journaled the shafts 17 17 extending parallel with the beams 1() 10 and carryrigidly thereon between the bars 14 and 16. Rigidly secured to the shafts 17 17 are the c'urved levers 19 19 in wardly above the beams 10 10 and' `beneath Specification of Letters Patent.

the rails 12 12 To cause the shafts 17 17 and the gears 18 18 to move simultaneouslyV and oppositely when any one ofthe levers `19 -55 19 is depressed, the gears are connected by the links 20 20', pivotally connected to and eX- tending from the upper .side of each gear to the lower side of the other. Engaging the gears 18 18 are the pinons 21 21, mounted" 6o upon shafts 22 22, journaled on the crossbars 14 and 16 and having crank-arms 23 23 extending beyond the bar 14 and toward the abutment 1 1".

To the abutment 11 are secured the ver- 65 tical guides 24 24, wherein is mounted to slide vertically a gate 25, provided-With slots 26 26 embracing the beams 10 10 and the rails 12 12. The crank-arms 23 23 are connected with the gate by means of the links 7o 27 27, pivoted to the gate, as by the pins 28 28.

Upon the levers 19 19 are supported the platforms 29 29 between the beams `10 10 and the rails 12 12" and connected, if pre 75 ferred, by a cleat', as 30. The cross-tie 13 may be provided with shoulders 31 31to engage the cleat 3() and prevent a displacement of the platforms. The platforms -may be further secured by hooked members 32, se- '8o cured to the under sides thereof and engaging beneath the beams 10 10. To cover the gearing, a plank 33 may be secured beneath i the rails and adjacent the gate.

In Figs. and 3 the gate is shown in a raised 8 5 position and the associated parts in the positions assumed when the gate is at the eX- treme of its upward movement. When the weight is removed from theplatforms, the weight of the gate forcesv the crank-arms 9o 23 23 downward, as indicated by thearrows, thereby rotating the pinons 21 21 the gears 18 18, and the levers 19 19, as indicated by their respective arrows, and to the-positions indicated in dotted lines and raising the platforms 29 29 to the level of the 'cross-ties 1 1 1 1 and 13, leaving the track unobstructed and the platforms inposition to be depressed.

It is evident'that an application of a weight to the platforms will move the parts in reverse order and raise vthe ate.

As the levers 19 are al rigidly secured to one shaft and the levers 19 to the other and as the rotary movementof one shaft moves the platform and a vertically-slidable gate operatively connected with the arms and movable to operative position When the platform is depressed.

2. The combination with a railway-track, of a depressible platform disposed beneath the same, shafts extending longitudinally of the track, laterally-projecting arms secured to the shafts and bearing against the botto-m of the platform, and a vertically-slidable gate operatively connected with the shafts and movable to operative position when the platform is depressed.

3. The combination with a railway-track, of a depressible platform, shafts disposed beneath the latform and provided with gear- Wheels, linls connecting said gear-wheels,lat erally-extending arms secured to the shafts and bearing against the bottom of the platform, a vertically-slidable gate, and pinions meshing with the gear-Wheels and operatively connected with the gate for moving the latter to operative position when the platform is depressed.

4:. The combination with a railway-track, of a depressible platform, shafts extending longitudinally of the track and provided with gear Wheels, laterally extending arms secured to the shafts and adapted to bear against the bottom of the platform, pinionsmeshing with the gear-wheels, a verticallyslidable gate, and crank-arms carried by the pinions and pivotally connected with the gate for moving the latter to operative position When the platform is depressed.

5. The combination with a railway-track, of supporting-beams extending longitudinally of the track, transverse braces connecting the longitudinal beams, shafts journaled in the braces and provided with gear -wheels, a depressible platform, laterally-extending arms secured to the shafts and bearing against the bottom of the platform, a vertically-slidable gate, links pivoted to one side of the gate, and pinions meshing with the gearwheels and provided with crank-arms the ends of which are pivotally connected to the links for movingr the gate to operative position when the platform is depressed.

6. The combination with a railway-track, of the cross-ties some of which are provided with recesses, a depressible platform disposed between the cross-ties, and a vertically-slidable gate operatively connected with the platform and movable to operative position when the latter is depressed, the upward movement of the platform being limited by engagement with the walls of said recesses.

7. In a cattle-guard, a vertically-sliding gate, angularly-m ovable arms connected with and to move the gate, shafts rotatably mounted, gears connecting the shafts and arms and whereby a rotary movement of the shafts moves the arms, levers rigidly mounted upon the shafts, and a platform so mounted upon the levers that a weight thereon rotatably moves the shaft.

8. The combination with a railway-gate, of shafts extending longitudinally of the track and provided with spaced gear-wheels connected by diagonally-disposed links, laterally-extending arms secured to the shafts, a depressible platform supported by said arms, and a vertically slidable gate operatively connected to the gate and movable to operative position when the platform is depressed.

9. The combination with a railw:ty-track, of the cross-ties, vertical guides secured to the ends of one of the cross-ties, a gate mounted for vertical movement between said guides, a depressible platform, shafts extended longitudinally of the track and provided with spaced gear wheels connected by diagonal braces arms extending laterally from the shafts and bearing against the bottom of the platform, and pinions meshing with the gearwheels and provided with crank-arms operatively connected with the gate for moving the latter to operative position when the platform is depressed.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
