RAILWAY-GATE.

Specification of Letters Patent. Patefited Dec, 30 1919;

Application filed April 9, 1918. SeriaI No. 227,501.

- To all whom it may concern:

Be it known that I, CORNELIUS A. Non- MAN, a citizen of the United States, residing at Brysoinin the county of Jack, State of Texas, have invented certain new and useful Improvements in Railwayfiratesy and I do hereby declare the following to" be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is an improvement in gates and has particular reference to a railway gate employed as a cattle guard.

An object of the invention is to provide an improved mechanism of simple and inexpensive construction for automatically adjusting a gate, which extends across a-track, from its closed or operative position to its opened position by the approach of a train.

Another object is the provision of improved means for returning the gate from opened to closed position after a train has passed the same.

The inventive idea involved is capable of receiving a variety of mechanical expressions one of which, for the purpose of illustrating the invention, is shown in the accompanying drawing wherein Figure 1 is a top plan view of a track showing the invention applied and with the gate in closed position.

Fig. 2 is a transverse section on the line 22 of Fig. 1 through the track with the gate and its operating mechanism in operative or closed position.

Fig. 3 is a similar view with the gate in opened position.

Fig. 4 is a sectional view on the line 1- 1- of-Fig. 1.

Fig. 5 is a section on the line 55 of Fig. 1.

Fig. 6 is an enlarged elevation of the re taining device for the gate when the same is in closed position.

Referring more particularly to the draw ing the numeral 10 indicates atrack with which is associated the gate 11 which may be of any desired construction and which extends transversely across the track when.

in its closed or operative position and which is adapted to be swungin a vertical plane transverse of the track to its opened or inoperative position. When closed, the free end of the gate is engaged between a pair of retaining members 12 carried by a post 13 mounted adjacent one ofthe rails of the track so that the gate cannot be opened by cattle.

Preferably positioned below the track 10 and transversely thereof: is apa-ir of spaced bearing members l-liaving a rotatable shaft 15 mounted in adjacent ends thereof. The end member 16 of the gate 11 extends below the track 10 and has its lower end fixed to the shaft 15 so that when the latter is rotated the gate will be swung in a vertical plane with the shaft as a pivot. The lower end of the member 16 is connected to the shaft between the bearings 14 and has disposed adjacent thereto a gear 17 also fixed to said shaft and meshing with another gear 18 supported by one of the bearings 14 and said gears are adapted to be rotated to actuate the shaft 15.

The mechanism for rotating the gears 17 and 18 so as to open the gate 11 upon the approach of a train preferably comprises a pair of tread members 19 arranged along side of the rail of the track adjacent the member 16 of the gate in such a manner as to be engaged by the wheels of a train. A tread member 19 is arranged on each side of the gate so that the same will be opened by the approach of a train from either direction and the end of the tread member remote from the gate is pivotally mounted as at 20. The adjacent ends of the tread mem; bers 19 are connected by a coupling plate 21 which is bent about said ends to house the same and to whichsaid ends are pivoted as indicated at 22 in order to permit of a depression of the tread members when the wheels of the train or car are engaged therewith. The coupling 21 is provided with a depending rack bar 23 which engages the teeth of the gear 18 so that when the tread members are depressed the train of gearing will be actuated to automatically open the gate as a vehicle approaches on the track.

After the train has passed, it is desirable that the gate be returned to its normal closed posiion and, for this purpose, an end of the shaft 15 which projects beyond one of the bearings 1 1 has secured thereto one end of a oounterbalancing weight 24: which normally depends in a vertical position, as shown in Fig. 3 but which is swung to a horizontal position, as shown in Fig. 3;

when-the tread members 19 are depressed.

The swinging of the weight 24 to its operated position is done against the action of a spring 25 one end of which is connected to the weight 2% while the other end is secured to the adjacent bearing 1% and after pressure has been removed from the tread members 19 by the passing of the train beyond the same the combined action of the weight 24 and spring 25 will be sufficient to overbalance the weight of the gate 11 and return the same to its closed position.

What is claimed is The combination with a track and a depressible track instrument, of a gate disposed in a plane transverse to the track and having at one end an upright that depends below the bottom of the gate and is provided at its lower end with a pivot shaft, spaced bearing plates in which the pivot shaft is journaled, a counterweight rigidly connected with the shaft, a spring connected with the counterweight in position to draw the weight to its lowermost position and swing the gate in the direction of the track, a pinion fixed upon the shaft and connections between the track instrument and pinion for actuating the latter against the tension of the spring, a v

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