GATE FOR RAI LWAY-TRAC KS.

SPECIFICATION forming part of Letters Patent No. 395,056, datedDecember 25, 1888.

Application filed March 9, 1888.

To all whom it may concern.-

.Be it known that we, WILLIAM RAMSEY JAcoBs and SAMUEL CALLAHAN HoUsToN, citizens of the United States, residing at Sulphur Springs, in the county of Hopkins and State of Texas, have invented a new and usef ul Improvement in Gates for Railway-'lracks, of which the following is a specification.

Our invention has reference to gates for To railway-tracks; and it consists in the improvements hereinafter described on the construction wherein a gate spanning the track is automatically operated by the train moving in either direction to swing the gate out of position.

In the drawings, Figure l is a plan view of a section of track having our improvements applied thereto. Fig. 2 is a side view of the construction shown in Fig. 1, the gate closing the track, the closed and open position of the parts being represented in full and dotted lines.

A pair of the central ties, A, are extended to bear upon and be secured to the upper edge of the vertical plates B, located below the plane of and at one side of the track. A central longitudinal brace, O, is interposed between the said extended ties, and has lo cated upon its upper face a sectional hearing, a, the opening in which is transverse and in line with openings formed in like hearings to, located upon the upper edges of the plates B. A transverse shaft, D, turns in said bearings u, and has its extended ends bent downward in the form of stirrups E, in each of which is a weight, b. The lower cross-bar, c, of said stirrup is removable, in order to provide for the convenient removal and application of the weight. Upon the iii- 40 ner side of one branch of each stirrup is located a horizontal pin, upon which is mounted a grooved wheel, d.

All inclined curved arm, F, is secured at its upper end to the side of the adjacent plate B and extends along in contact with the grooved face of the roller, in order that said roller may move upon said bar, and the lower end of said bar is connected by a link, e, with the longer end of a lever, G, which is fulcrumed near one end to form a long and seen No. 266,695. (No model.)

short lever portion. The longer portion of said lever plays in a vertical guide-strap, H, secured on the side of the adjacent plate 13, and serving to limit the vibrations of said lever, while the short end is provided with a shoulder, f, upon which bears the outer bent end, g, of an extended arm, I, located at right angles to the track and secured at its inner end to the side face of one of the ties A. Said arm I is provided adjacent to one of the track-rails with a vertical lug, h, which has a shouldered notch formed in its upper end, and in which shoulder bears the free portion of a longitudinal bar, J, one end of which is pivotally secured to a metallic chair, t', 10- 6 5 cated at some distance from the arm I in order that said bar may exert a proper leverage. A tie adjacent to that carrying the chair i is provided. with a vertical guidebracket. The free end of the bar J, beyond the lug 71, is curved downward between the ties, where its end is guided by playing in a cut-away portion in the side of a spring-plate, K, secured in an inclined position to two of said ties.

The arrangement of levers, weights, &c., on the opposite side of the track is the same as that described.

The pickets J are secured vertically in the shaft D, each picket being tapered toward the top, and the base of each picket is inserted in the shaft D, and secured in position by means of bolts 75. As a train approaches from either direction, its wheels depress the bar J to effect the descent of the arm I, 8 5 thereby throwing the longer end of the lever G upward, and effecting the lifting of the arm F, thereby causing the roller to move along said arm, carrying with it the stirrup and weight to the position shown in dotted lines. 0 This movement of the weight and roller effects the turning of the shaft D in its bearings, so as to throw the pickets downward to a position substantially parallel with the rails and road-bed. 5

By reference to Fig. 1 it will be noticed that the rails are located between two of the pickets. The movement of the train over and past the gate brings the wheels onto the other bar J to depress the same and raise the other I arm F, so that the gate will be maintained in.

a lowered position until. the rear wheels have passed entirely from both bars J.

Each arm F has a slight: double incline, at;

5 the highest point of which is placed a triction-roller, l. \Vhen either arm F is raised,

the existence of the incline aids in determin ing the direction of the movement given to From the foregoing it will be seen that the 5 construction described is not onl vsimple and eiticient, but will operate with certainty bv the moven'ient ol the train from either dirce- 5 'tion.

A guide-strap. m. is located on the end ot' each plate H, to limit the movement of the arm I.

The position of the roller prevents the parts from occupying a dead-(enter relative tothe lever devices.

'6 elainil. The eombinat ion, with a shalt crossing a railway-track and provided with weighted de- 5 pcl'lding ends carrying rollers,o[ an arm serving as a track to slide under said roller and turn the arms, lever apparatus connecting said track-arm with a verticall v-moving bar located mljaeent to the rails, and a gate connected to said shall, as set forth.

2. The combination, with a shaft. crossing a railway-track and provided with weighted depending ends, of rollers connected eccentrically to said ends, a gate connected to said shaft, and lever and bar apparatus for operating said weigl'lted ends from the vicinity of the rails, as set forth.

3. The combination, with the transverse gate and its shaft, the latter having its ends bent and weighted, of rollers connected to said ends, a pivoted track-arm having a triotion-roller, and lever apparatus and connections for vibrating said pivoted arm, as set forth.

a. The eomhimition, with the transverse gate and its shaft, the latter having its ends bent and weighted, of rollers connected to said ends, a pivoted arm having a frictionroller and serving as a track for said weighted roller, lever apparatus for vibrating said arm, and a vertical limiting-stop, IT, as set forth.

The combination, with the gate, its shaft, and the weighted roller ends of the latter, ol lever devices for connecting said ends with a wheel-bar located parallel with one of the rails and lH'UVltlOtl with a tree depending portion, and a guide-plate tor the same, as set forth.

ti. The combination of the gate-shalt having bent ends, weights secured to the latter, lever apparatus for moving said weighted ends, and an arm, 1, provided with a shouldered lug connecting said apparatus with a wlnwl-har bearing on said lug, as set forth.

In testimony that we claim the 't'tn-egoin gas on r own we have hereto a tlixed our signal tires in presence of two Witnesses.
