UNITED STATES DANIEL HEWITT, OF FORT WORTH, TEXAS.

HIGHWAY vsnnim'n.

Application filed March 18, 1929.

My invention relates to signals and more particularly to signals for the intersections of highways, railway crossings or crossing of highways and railways, and curves and the like; and the object is to provide signal devices which will be automatically operated by the passing of the wheels of a vehicle over certain actuating devices and to provide devices which will be positive in action and which are simple in construction and operation and which will serve as warning against the passage in case of danger. Other objects and advantages will be fully explained in the. following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application.

Fig. 1 is a perspective view of a roadway and the signal devices mounted thereon.

Fig. 2 is an interior elevation of the signaling devices.

Fig. 3 is a transverse section of a road bed, showing the main actuating bar.

Fig. 4: is a vertical section, taken substantially on the line 47-41: of Fi g. 3.

Similar characters of reference are used to indicate the same parts throughout the several views.

The drawings show a portion 7 of a road bed having a transverse groove 6 therein. A rod or pipe 5 is mounted partly in the groove 6 and projects slightly above the road bed. The rod 5 is yicldingly supported in frame members 1 and 2 which may be of concrete or other material. Rods 4, L- shaped, are operatively connected to the rod or pipe 5 and project loosely through the upper sides of the frame members 1 and 2. Metallic plates 8 are attached to the upper side of the lower parts of the frames 1 and 2 and the rods 1 project loosely through these plates 8. The plates 8 protect the frame members against wear, and also form seats for the springs 9. The springs 9 are mounted on the rods et and held thereon by nuts 10 and washers 11 form seats for the upper ends of the springs. The tension of the springs 9 may be controlled by the nuts 10. When a vehicle runs over the rod 5, this rod will be depressed and after the passage of the vehicle the springs 9 will restore the Serial No. 347,762.

rod 5 to normal position to be engaged by the next passing vehicle.

Vertical brackets 14 are attached to the frame 1 parallel to the arms or rod 1 and knockers or clappers 13 are pivotally mounted in the brackets 14 with ends projecting towards the rod 1. Across bar or pin 15 is rigidly mounted in the rod 4 and projects from both sides thereof adapted to strike the knockers or cla'ppers 13. Metallic disks or sounding devices 12 are suspended from the upper member of the frame 1 in position to be struck by the knockers 13.

Then a vehicle runs 011 the bar 5, the bar 5 will be depressed suddenly carrying the pin 15 which will actuate the knockers 13 and cause the knockers to strike the sounding devices 12. This will be done as often as a vehicle runs on the bar 5. The rods 14- are held against displacement by the frames 1 and 2. Blocks 16 are mounted in the bottom of groove 6 to limit the down ward movement of the bar 5. These blocks 16 may be made of any suitable material.

What I claim, is,-

1. Signaling devices for highway crossings comprising a depressible bar and provided with vertically extended members, a guide frame for said members and said members adapted to move freely in said guide frame, springs operatively associated with said members for restoring said members to normal position after a depression, an actuating pin carried by one of said members, sounding devices suspended from the frame on opposite sides of said pin, brackets attached to said pin carrying member, and knockers pivotally mounted in said brackets having arms projecting in the path of said pin and arms projecting under said sounding devices and adapted to strike said sounding devices when actuated by said pin.

2. Signaling devices for highway crossings, (the highway being provided with a transverse groove,) comprising a depressible bar mounted partly in said groove and pro jecting above the surface of the highway and provided with upstanding guide arms, one arm being a signal actuating arm, a rectangular supporting and guiding frame for one of said arms, a rectangular signal-carrying frame for supporting and guiding said signal actuating arm, springs mounted on said arms and confined between the members of'said frame for restoring'said arms and bar. to normal position after a signaling operation, soundin devices suspended in said '5 signal-carrying frame, an actuating pin carried by said signal actuating arm, and knockers of clappers pivotally mounted in said signal carrying frame and each knocker having one arm projecting in the path of said pin and another arm adapted to strike 1 a sounding device when actuated by said pm.

In testimony whereof, I set my hand, this 5th day of March, 1929.

DANIEL HEWITT.
