UNITED STATES PATENT; orrron ALBERT J. PAYN'TER, OF ALTON, KANSAS.,

To all whom it may concern:

Be it known that I, ALBERT J. PAYNTER, a citizen of the United States, residing at Alton, in the county of Osborne and State of Kansas, have invented new and useful Improvements in Safety Devices for Railroad-Crossings, of which the following is a specification. I

This invention relates to improvements in safety devices for railroad crossings, and contemplates the provision of a simple, re liable, and effective crossing barrier and signal which will be automatically .operated by the passage of trains. It is further pro-n posed to improve the operating mechanism by eliminating the use of electricity, and to incorporate therein a simple and effective device whereby the signal-setting device will only be operated by a car passing in one direction.

One embodiment of the invention whereby the above enumerated ends are effected is described in the specification below and illustrated in the drawings, the original features being pointed out in the claims.

In the drawings-* Figure 1 shows a railroad crossing provided with the barrier and signal comprised in the present invention.

Fig. 2 is a fragmentary side elevation of the signal arm and supporting structure, showing parts of the mechanism for moving the arm to the safety position, and the retaining device for the arm.

Fig. 3 is an end view of the arm and sup: porting structure.

Fig. 4 is a fragmentary view illustrating the portions of the setting device associated I with the track rail, and

Fig. 5 shows the tripping device and loose coupling in detail.

Referring to the drawings more specifically, the signal has a supporting structure shown in the drawings as a post or standard 1 bifurcated toward the upper extremity for receiving the barrier and signal arm 2 pivotally mounted toward one end for movement in a vertical plane by means shown as a biolt 3 passing through the arm and standar To normally retain the arm 2 in an upward position indicative of safety, a catch 4 is pivotally attached to the face of the standard 1 and provided with a spring 5 whereby it is maintained in the path of the long end of the arm 2. The catch 4 is con- Specification of Letters Patent. 1

, Patented Oct. 1', 1913; Application filed December 7, 1917. Serial No. 206,054. 4 4 I nected by a link 6 to a bell-lever 7 pivotally I mounted in the present instance on the side of the standard toward the base. i From the other arm of thebell-lever 7 suitable con necting means shown as a wire 8 extends to-' ward a contact element illustrated as a trip lever 9 and the end of the wire 8 is aloose coupling 11 preferably including a spiral spring 12 of suitablestrength to maintain the wire 8 tightly stretched and a second spring 13 is provided, tending in the opposite direction to maintain the trip-lever '9 in the path of the wheels of a car.

It will be seen that in the passage of a car in one direction, the catch/1 will be released to permit the long end of the arm to move downward to a position indicative of danger, while in the passage of a car in the other direction no result will follow.

To restore the arm 2 to the upward position a lever 14 has one end pivotally mounted in proximity to the track and the other end extended toward the standard 1 and 2 provided with an upwardly disposed arm 15 terminally connected by a link 16 to the the elevated position by the catch 4 the lever is permitted free upward movementfwhile in the lowermost position of the arm the weight of the arm is sustained by the link j horizontal -posij and lever to'maintain it in tion.

It will be obvious that by providing a second trip-lever disposed on the other side of the crossing and similarly connected to the catch, the device may be utilized for trains in either direction.

The herein-described embodiment of the invention is intended merely for purposes of illustration, and is not to be interpreted as in any way limiting the spirit or scope of I the invention, such limitation being confined to that indicated by the latitude of the claims.

Manifestly the arm? is adapted to serve the two-fold purpose of-signalarm and bar 1 rier, Fig. 1, though I do not limit myself to the employment of an arm sufliciently long to serve as a barrier.

What I claim is 1. 'I he combination with a railroad crossing arm, of a lever disposed-parallel to: a track rail and having linked connection at one end to-the arm, a pivotally mounted trip-bar overlying the lever with one end in juxtaposition to the track rail, whereby in the passage of a car the leverwill be actuated to 'operatethe arm to safety position, means for retaining the armin the safety position, andcar-operated means forreleasing'the last-mentioned means to allow the armto move to danger position.

Copies of this patent may be obtained for track rail and having linked connection to the, arm, a pivotally mounted trip bar overlying the lever with one end in proximity to the rail, a spring pressed catch on the arm support normally disposed in the path of the i arm to retain the arm in the safety position,

a contact element pivoted in proximity to the track rail, connecting means between said element and said catch whereby in the actuation of said element'by a car moving inone direction the catch will be displaced from the path of the arm, and a loose coupling in said connecting means whereby said contact element will not be aiiected by the actuation of said element by a car moving in the other direction. 1

In testimony whereof I afiix my signature. ALBERT J. PAYNTER.
