AUTOMATIC RAILWAY-GATE.

SPECIFICATION forming part of Letters Patent No. 514,795, dated February 13, 1894. Application filed January 6, 1893. Serial No. 457,528- (No model.)

To all whom it may concern:

Beit known that I, GOVERNOR D. WARREN, of Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Automatic Railway- Gates; and I do hereby declare the following to be a full, clear, and exact description of the nvention, such as will enable others skilled in the art to which it pertains to make and use it, reference being bad to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in automatic railway gates; and it consists in 1 view partly in section.

p and journal box.

the novel combination and arrangement of parts which will be'fully described hereinafter, and more especially referred to in the claim hereto annexed.

Referring to the accompanying drawings, Flgure 1 is a plan view of a track showing mylmproved gate applied thereto. Fig. 2 is a side elevation of the same. Fig. 3 is an end Fig. 4 is a detached yiew of the center oscillating shaft. Fig. 5 1s a slmilar View of the combined rail brace Fig. 6, is a detail perspect1ve v1ew of one of the guide and supporting castings located beside the rail showing the pivoted arms or crank shaft therein, and in dotted lines showing the movable rails operated by the car wheels.

A, designates the main rails, B, the cross ties and O, the longitudinal ties or beams located beneath the gate.

Journaled beneath the rails A, and upon the beams O, is the shaft D, and projecting from the latter upward along the outer sides of the rails A, are the double arms E.

Near the respective ends of the shaft 0, are the studs F, and F, which respectively extend above and project beneath the said shaft. Secured at their inner ends to these studs are the, oppositely extending coiled springs G,

which latter may be secured at their outer ends to the cross ties B, or beams O, as desired. These springs counteract each other and in consequence hold the shaft D. nor.- mallyin one position. Now the pickets H, of the gate, preferably formed of sheet steel, are secured to the shaft D, so as to extend vertically with the said shaft in its normal position.

For automatically operating the gate by a train approaching in either direction a rail I, is extended outward on each side of the gate, the same being located on the outer sides of the respective tracks and loosely secured at their inner ends to the arms E, of the shaft D. These rails incline toward their outer ends so that at the latter points they are substantially flush with the main tracks. Suitably secured to the cross ties at intervals between the ends of the rails I, are the castings J having a bed plate or portion K, extending beneath the bottom of the 'rail which at its inner end is bent upward to grasp the rail flange brace for the same. From the outer end of this casting projects the wall L, having a countersunk inner side L, and between this wall and the rail works the arm M, having a journal N, atits lower end mounted in suitable boxings in the bed plate K. Eyes 1, depending from rails I, are loosely connected to the upper ends of these arms. By this construction the rails I, are held securely in the desired position. The inner recessed side L of the wall forms a guide as well as a portion of the covering for arm M.

Journaled upon the cross ties at the ends of the movable rails I, arethe short shafts 0, having projecting studs 0', to which the said rail ends are loosely secured and at the outer ends of these shafts are the crank arms P, to which the coiled springs Q, are connected, which latter the rails pull against when moving forward to open the gate. A head R, is formed on oneend of the shaft D, adapted to receive a wrench S, for the purpose of turning the gate down by hand when so desired. The wrench is hooked at its outer end to engage a ring secured to the track in a convenient position so that the gate may be held down as long as desired.

In operation an approaching train engages the outer end of the rail I, and in depressing it-swings it forward on its arms M, and the longitudinal movement of the rail thus secured is sufficient to push the crank arms E, of the shaft D, into a substantially horizontal position thus acoomplishin g the oscillation of the latter and the lowering of the gate beneath the rails A, out of the way of the passing train. The operating rails are preferably thus forming a secure operate the same.

extended about sixty feet in each direction from the gate so as to afford ample room to After the train has passed entirely over the rails it Will be readily understood that the several springs will automatically return the gate to its normal position. If from any cause the automatic operation should fail the pickets being formed of flexible steel will simply be pushed over by the passing train only to spring back again when the latter has passed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination of the picket shaft extending beneath the rails and provided with the upwardly extending cranks between the rails, springs yieldingly holding said shaft,

the tread rails extending along the rails, as described, and at their inner ends pivotally joined to the said cranks, a series of stationary guide blocks extending up beside each tread rail, the series of arms at their upper ends loosely joined to a tread rail, said arms being jonrnaled at their lower ends in said guide blocks and shielded thereby, and spring held crank shafts to which the outer ends of said tread rails are journaled, substantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.

GOVERNOR D. WARREN.
