LYNDON ARNOLD, OF ST. J OHNSBURY, VERMONT.

RAI LWAY-CAR GATE.

SPECIFICATION forming part of Letters Patent No. 481,540, dated August 23, 1892.

Application filed May 1, 1891. Serial No. 391,220. (No model.)

To all whom it may concern:

Be it known that I, LYNDoN ARNOLD, a citizen of the United States, residing at St. J ohnsbury, in the county of Caledonia and State of Vermont, have invented a new and useful Railway-Oar Gate, of which the following is a specification.

My invention relates to improvements in railway-car gates in which a gate is operated on the car-platforms for the safety and convenience of passengers; and the objects of my improvements are, first, to provide a substantial gate to prevent persons from falling or stepping off the platform; second, to afford facilities for opening and closing the same quickly and easily; third, to secure the same open or closed, and, fourth,to provide a clear passage-way when the gate is open. I attain these objects by the mechanism illustratedin the accompanying drawings, in which- Figure 1 is a vertical section of the entire mechanism. Fig. 2 is a vertical section of the gate raised or open. Fig. 3 shows framework with parallel bars detached. Fig. 4C is a section of device for holding gate open with grip loose. Fig. 5 is a section of holding device with grip fast on rod. Fig. 6 is a vertical end section.

Similar letters refer to similar parts thro ughout the several views.

The center piece A, side pieces D and E, with parallel bars B and O, constitute the framework of the gate. The side piece E is securely fastened to the corner of car or other suitable support, side piece E is connected with the center piece A by means of parallel bars 0, and center piece A is connected to side piece D by parallel bars B. All the connections of parallel bars B and C with side pieces D and E and center piece A are by means of bolts, forming hinge-joints. Side piece D has at its lower extremity a double flanged roller running in grooved track flush with platform. At the end next the car and side piece E the track ends in a starting-block G for roller F. The top parallel bar B is continued past center piece A, forming lock-lever J, which is made to engage with catch H on the top of side piece E. At its other end it is made to engage with catch I, thus fastening the gate securely when closed. A cord M is attached to lock-lever J by means of ring L and passes up and over rollers N down to ring 0 on eccentric P, Fig. 4, which is pivoted in sliding sleeve R and provided with a grip-lever S. The eccentric P is pivoted in sleeve B, so that when lever S is held close to rod Q the eccentric does not touch rod Q, but allows sliding sleeve R to move freely up and down on rod Q, as shown by dotted lines in Fig. l. The cord M is attached to eccentric P in such manner that when the grip-lever S is released it causes eccentric P to turn toward the rod Q, gripping it and holding it locked in that position until released by grip-lever S being forced down.

In raising the gate the grip-lever S is held close to rod Q, turning eccentric P till it releases its grip on rod Q. The sliding sleeve R is then drawn down on rod Q, pulling cord M over rollers N and raising the end L of lever J, which lifts center piece A and all the ends of parallel bars B and C that are connected to A, drawing side piece D toward side piece E. At the same time that center piece A is raised side piece D, moving on roller F till the roller F strikes starting-block G, when the grip-lever S. being released, the weight of gate on cord M raises the side 0 of eccentric P, looking it against rod Q and holding the gate in that position.

In closing the gate, lever S is held down, releasing eccentric P, when sleeve R slides upon rod Q, releasing the tension on cord M, allowing roller F to roll off starting-block G, when the weight of center piece A tends to bring parallel bars 15 and G into horizontal line and closing gate, and by pushing side piece D toward rod Q allows end K of lever J to engage with catch I, and end L of lever J engages catch H, locking the gate.

I am aware that prior to my invention cargates have been made to close the passageways to car-platforms. I therefore do not claim such a combination, broadly; but

Vhat I do claim my invention, and desire to secure by Letters Patent, is-

1. A railway-car gate coinprisinga stationary side piece and a horizontally-sliding side piece, each pivotally connected to a verticallymovable central piece, and means for raising and lowering the central piece to open and close the gate, substantially as specified.

2. In a car-gate, the combination of the vertically-tnovable center piece A, connected by parallel bars B and O to side pieces D and E, substantially as described.

3. The parallel bars B and (J, hinged b 5 joints V to center piece A and at the other end to side pieces D and E, as shown.

4. The combination, in a car-gate, of the starting-block G, grooved track, and flanged carrying-roller F, substantially as described.

10 5. The lock-lever J, pivoted by joints V to center piece A and side piece D and engaging catch H at one end and catch I at the other, for the purpose specified.

6. The combination, in a car-gate, of the 15 rollers N, cord M, loop L, eccentric-loop O,

pose specified.
