Patented July *7 1914.

Application led April 10, 1914. Serial No. 831,068.

To aZZ whom it may concern Be it known that I, LA MARCUS A. THOMP- soN, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented a new and useful Improvement in Safety Devices for Pleasure-Railway Cars, of which the following is a full, clear, and exact description,

force. It is, therefore, advisable to provide means for locking the riders iii their seats. This has been done by providing a safety device comprising a pivoted handle bar which may be swung forwardly to allow riders to enter the carfand assume their seats yand then swing rearwardly to bring the bar into position in front of the trunks and above the legs of the riders. Means have been provided to secure the safety de 'ice inl locking position and also to release the same to allow the riders to enter and leave the car.` The object of my invention is to provide new and improved locking means accomplishing the results above set forth whichy will have certain advantages over known means in respect to simplicity of construction and operation and unlikelihood of getting out of order and in respect to its possession of other advantages and functions, all of which will be more fully understood by reference to the particular description in connection with the drawings, in which:

Figure l is a perspective view of the track, loading and unloading stations, and cams for releasing safety device. Fig. 2 is a sectional perspective view o-f part of a car with safety devices applied thereto. Figs. 3 and 4 are side elevations, respectively in locked and unlocked position, of the safety device. a is the loading station, b the unloading station, c the' track,"and Z the car. The safety device is in the form of a yoke comprising the cross bar c and arms f, f, each of the lattei being pivotally mounted between vertically extending guide plates g, g, within, and projecting from the rear wall of, a casing i secured to the car body.

Within the channel formeel between the guide plates g, g slides a locking bar z'. The

upper end of the channel is closed by a crosspiece or stop m, while a cross-piece or stop n connects the lower ends of the guide plates and is adapted to limit the downward movemeant of the bar z' by engaging a projection j on the bar. y

The upper end of the bar/Z is widened to form a cam 7c which is widest at its top and tapers downward and thence extends abruptly inward to form a shoulder Z. The

pivoted end of the arm f is also enlarged to form an upwardly and inwardly projecting Zhen the bar is held in a raised position, the arm 7 is free to move forward and up ward on its pivot, the high point of the cam 'o passing under the shoulder Z. Or if the Vbar is lifted substantially above its lowest position, but not to its extreme upper position, the cam o will act upon cani 7c to raise Athe bar z' to its eXtreme upper position and allow the high point of the Cain 0 to ride under the shoulder Z. As the arm f is completing its movement into its eXtreme upper or forward position, the high point of the rcam o moves slightly downward in an inclined direction, allowing the spring cushion or spring p, between the upper end of bar z' `and the stop m, to move the bar c' slightly downward, thus releasably holding the arm f in its upward oi` forward position, but per-` mitting it to be depressed with the exercise of moderate manual force.

When the yoke e f is swung downward and rearward into its locking position, the

bar i, unless otherwise upheld, drops until the lproject-ion '7' abuts against the stopy n, placing the cam 7c in such position that it acts as-a stop against the campo to prevent the arm f from being swung upward and forward.

Each bar z' extends downward beneath the car-body and is in alinement with cams s, t, arranged along the track. One pair of cams is provided at the loading station and another pair at the unloading station.

Let it be assumed that the car is' traveling along the course and that the yoke c f has been swung into position to lock the occupants in their seats, and that each bar i has dropped so as to prevent the yoke e f bars z' sufficiently high to allow the yoke e f to be swung into position to free the passengers. So long as the car remains at the unloading station, the yoke c f can be freely l swung in either direction. In the travel of l lower ends of bars z' engage cams t, which,y like cams s, lift the bars z' high enough to the car. from the loading station to the unloading station, the bars z' pass beyond the cams s, If the yoke e f has been moved into its unlocking position, it remains in that position owing to the downward pressure of the shoulder Z against the cam 0i. If

the yoke e f has been moved into its lock-A ing position, the bars a' drop as soon as they pass beyond cam s, thereby locking the yoke in its locking position.V When the car reaches or nears the loading station, the

permit the return of the yoke e f into position to allow ready ingress to the cars. So long as the car remains at the loading station, the yoke 'e f is freely movable from either position to the other. Before the car starts, the attendant swings the yoke e f into position to retain the passengers in their seats and as soon as bars z', in thev 'starting movement of the car, move beyond cams t, the bars drop and lock the yoke from being swung into its unloading position.

yoke e f and the locking bar Having now fully described my invention; what I claim and desire to protect by Let-l' ters Patent is-- l. In a pleasure railway, the combination withy the car, of a safety device movable thereon for locking the passengers tov their' seats, and a vertically lextending locking bar slidable in the direction of its length and adapted to be upheld 'by the safety devicel when the latter is in locking position and to slide down by gravity, the safety device is moved into lockingposition, into position to lock the safety device from re-l turning. i l
