On opposite sides of the track are provided with slots 34 and at their lower 100 are Vpits 7, one to one side of the roadway ends with eyes 35.r Pins 36 extend'll, vSlots 34 and 30 to provide pin and slot connections between the levers 28 and the bars 33. Springs 38 are anchored to the eyes 35 and to a foundation member 39 at the bottom of the pit for normally holding the bars downwardly and the free ends of the levers in engagement with the anti-friction rolls 29. A block 40 is mounted on the platform 11 above the rocker bracket 10 and tapers from an intermediate portion c as is indicated at a, away from the tracltway while the other end tapers toward the trackway as is indicated by o. Inclined openings 41 extend from the top surface of the upper end ofthe portion c to the bottom surface of the portion a in parallelism with each other and in substantial parallelism with the upper surface of the portion a. through the openings, terminating at one end in eyes 43 and adjacent the other endbeing formed with slots 44. intermediate portion c extends through the slots 44, thereby limiting the movementA of these bars 42. Springs 46 are engaged with the-eyes 43 and anchored on the platform 11 to hold the bars inwardly of the openings.

A pair of tables 48 are engaged withthe bars 42 and with the bars 33 and extend between the two blocks 31 and 40 in a taut condition. Y

If no train is approaching andthe bolts 19'are properly set in their normal position, an automobile riding on the platform may pass freely there over. n However, should the train be approaching and the switch 25 be closed to cause energization of the motor 23, it will be seen that the bolts 19 will be withdrawn so that when an automobile rides onto the platform 11, the platform will tilt and the front axle' will engage on the cables 38 and the ends of these cables adjacent the block 31 will be raised because the platformwill rock the lever 28 thereby pushing the bars 33 upwardly, placing the cables on an incline upwardly in a direction of movement of the automobile, so that the automobile will be brought to a gradual but positive stop and be unable to cross the railroad track.

lt is thought that the construction, operation, utility and advantages of'this inven- Vtion will be now quite apparent to those skilled in this art, without a more detailed description thereof.

The present invention hasbeen disclosed in detail merely for the purpose of exemplication, since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

- It will be apparent that changes in the details of construction and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or `sacrificing any of its advantages.
