UNITED STATES STINE L. JONES, OF BATON ROUGE, LOUISIANA.

RAILROAD-CROSSING GATE.

Application filed March 19, 1921.

To all whom it may concern:

Be it known that I, STINE L. Jones, a citizen of the United States, residing at Baton Rouge, in the parish of East Baton Rouge and State of Louisiana, have invented new and useful Improvements in Railroad- Crossing Gates, of which the following is a specification.

This invention relates to railroad devices, particularly to crossing gates, and has for its object the provision of a novel mechanically operated gate lowered at the crossing automatically upon the approach of a train.

An important object is the provision of a device of this character which requires ab solutely no manual manipulation whatever, the lowering of the gates being effected by movement of a train engaging member and raising of the gates being effected by spring action.

Another object is the provision of a device of this character in which the crossing gate is formed as an arm carrying a plurality of flexible members upon which are hung bells which will be jingled as the train passes over the operating device so as to effectually apprise persons that a train is approaching.

An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture, highly eiiicient in use, durable in service, and a general improvement in the art.

\Vith the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which- Figure 1 is a side elevation of my device complete,

Fig. 2 is a plan View,

Fig. 3 is a longitudinal sectional view through the special rail on a larger scale,

Fig. 4 is a plan view thereof, the underlying parts being shown by dotted lines,

Fig. 5 is a cross sectional view on the line 5 of Fig. 4e, and

Fig. 6 is a cross sectional view on the line 6-6 of Fig. 4.

Referring more particularly to the drawings, the letter A designates a trackway and B designates a crossing. In carrying out my invention I provide a specially constructed rail 10 interposed in one of the ordinary rails and comprising an elongated body 11 formed with a longitudinally extending Specification of Letters Patent.

groove 12 for the passage of the flanges of the wheels at one side of a train, the treads of the wheels passing over the body itself. This special rail member is formed with a trapezoidal recess 13 and has its lower surface formed with a semi-cylindrical recess 14-. I

Disposed beneath the rail section 10 is a casting 15 which includes a saddle portion 16 secured to the bottom of the rail section and this saddle portion is formed with a central hole 17 and two pair of sockets 18. This casting 15 further includes an arm 19 extending laterally beyond the rail and formed with a channel guide 20. The upper surface of this casting 15 is formed with a plu ality oi alined semi-circular recesses 21 which are complementary to the recesses 1% and which cooperate therewith to form bearings. The projecting portion of this casting 15 is formed with a pair of semi-circular recesses I Secured upon the projecting portion of the casting is a cap member 23 having a channel guide 24 complementary to the channel 20. This cap is also formed on its underside with semi-cylindrical recesses 25 which are complementary to the recesses 92 and which define bearings.

Journaled through the recesses 1i and 21 and and 25, is a shaft 26 which carries at one end a small pinion 27 and near its other end a larger pinion 28 located within the mating channels 20 and 24.

Disposed within the recess 13 of the rail is an operating member formed as a shoe 29 from the underside of which extends a rack 30 slidable through the hole 17 and meshing with the pinion 27. A plurality of coil springs 31 fit within the sockets 1S and engage against the inside of the shoe 29 for resiliently opposing downward movement of the shoe and for holding the shoe normally elevated in engagement with the inclined sides of the recess 13.

Located at some point near the crossing is a supporting arm 32 which carries upstanding cars 33 between which is journaled a lever arm 34- having its lower end formed as a segmental gear 35 and having its upper end formed as an upwardly inclined arm 36 adapted to extend across the crossing. Depending from this arm 36 are flexible members 37 from which are suspended bells 38.

Slidable along the bottom of the opening between the cars 33 and through the mating channels 20 and 24, is a longitudinally movable bar 39 which is formed at one end with rack teeth 40 meshing with the segmental gear 35 and formed at its other end with rack teeth 41 meshing with the pinion 28.

Ordinarily the shoe 29 is in elevated posi-' shaft 26 and gear 28 and this will result in longitudinal movement of the bar 89. The movement of the bar 39 will swing the lever 34Q and move the arm 36 downwardly at the crossing. As the shoe 29 is spring-pressed upwardly it will vibrate up and down as the successive wheels of the train pass over it and this agitation will be imparted to the arm 36 and will cause a continuous jingling of the bells 38 so as to warn all persons near that a train is approaching. After the train has passed by the springs 31 will operate to return the parts to normal position.

While I have shown and described the preferred embodiment of my invention, it is of course to be understood that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. In a trackway, a depressible shoe engageable by the wheels ofa train whereby to be moved downwardly, springs normally urging said shoe upwardly, a rack depending from said shoe, a shaft, a pinion on said shaft meshing with said rack, a second pinion on said shaft, a lever pivoted adjacent a crossing and having an inclined arm serving as a gate, a segmental gear on said lever, and a longitudinally slidable bar having its ends formed as racks, one rack engaging the second named gear and the other engaging said segmental gear.

2. In a. trackway, a depressible shoe engageable by the wheels of a train wherebyto be moved downwardly, springs normally urging said shoe upwardly, a rack depending from said shoe, a shaft, a pinion on said shaft meshing with said rack, a second pinion on said shaft, a lever pivoted adjacent a crossing and having an inclined arm serving as a gate, a segmental gear on said lever, a longitudinally slidalole bar having its ends formed as racks, one rack engaging the sec ond narned'gear and the other engaging said segmental gear, and a plurality of bells flexibly suspendedfrom said gate arm.

3. In atrackway, a rail section interposed in one of the track rails and formed with a recess, a shoe Within said recess normally projecting into the path of travel of the treads of the wheel of a train, a pivoted lever adjacent a crossing to be protected having one end serving as a gate and having the other end provided with a segmental gear, a longitudinally movable member having one end formed with rack teeth engaging said segmental gear and having its other end provided with rack teeth, a supporting member extending laterally from said rail section formed with a channel guide, a shaft journaled transversely of said track section and said lateral support, a pinion on said shaft within the channel meshing with the second named set of rack teeth, a second pinion on said shaft, and a rack depending from said shoe and engaging said last named pinion.

In testimony whereof I affix my si nature.

STINE L. Jo ivEs.
