To all whom it may concern:

Be it known that I, 1)UDLEY T. FISHER, a citizen of the United States, residing at Golumbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Highway Crossing Devices for Electric Railways, of which the following is a specification, reference being bad therein to the accompanying drawing.

This invention relates to improvements in highway crossing devices for electric railroads, having the trolley wire so low as to interfere with the passage of vehicles across the track.

The object of the invention to provide a means whereby a section of the trolley wire is automatically raised after the passage of a locomotive to provide clearance for vehicles, and automatically lowered into operative position at the approach of a locomotive.

Figure 1 is a perspective view of a high way crossing device embodying my invention. Fig. 2- is a view of the upper part of one of the poles, looking longitudinally of the track. Fig. 3 is a side view of the pole shown in Fig. 2. Fig. 4 is a detail drawing showing the operating mechanism.

In the drawings 1 is a locomotive running along the track 2, receiving power through a trolley 3, and the trolley wire 4. The trolley wire, except at the highway crossing, is suspended from brackets attached to the poles 11, or in any usual or preferred manner.

At each side of the highway are poles 55 having brackets 66 to support the ends of the trolley wire 4:. Journaled at 7-7 are counter-balanced arms or semaphores 8-8, to the ends of which is attached the trolley wire 10. The ends of this wire are secured to the next adjoining poles 11 by the eye-bolts 12. It is desirable that the eye-bolts 12 on the poles 11 exactly in line with the journals 77 in order that the wire 10 may be held in uniform tension in all positions of its travel. The semaphores are provided with sheaves 13-13 over which the chains 14 pass in such a manner that their movement tends to rotate the sheaves and with them the semaphores, causing the wire 10 to travel to a higher or lower position according to the direction of rotation. The forks 15-15 on the brackets 66 receive the semaphores 8-8 and hold them in exact longitudinal. position at the lower end of their travel while similar forks ill-16, located at the upper part of the pole, hold them in place when at their uppermost position. Electrical connection is made through the wire 10 when in its lower or operative position through the forks 15-15. The chains 14: pass downward and are guided over horizontally pivoted sheaves 171.7 and 18-48 to vertically pivoted sheaves 19 19 and 2020. The ends of chains ii are connected to wires 2121 which lead to operating mechanisms Q2 22 located be side the track at convenient distances from the highway crossing. These operating mechanisms consist of loosely mounted sheaves 2323 and 2l24c, chains 25-25 passing over these sheaves and connected at their ends to the wires 21-21' by the coil. springs 26-26 and 2727', and guide pulleys 28-28. 29 29 are spurs mounted upon the chains 25-25 so that when the wire 10 is in its uppermost position, they will be immediately above the centers of the chains 93-23.

The distance between the two sheaves of the operating mechanisms is such that the motion of the wire 10 and the semaphores 8 8 from the uppermost to the lower or operative position will cause the spurs 2929 to move to positions immediately above the centers of the sheaves Qt-Qt.

31 is a projection conveniently located on the locomotive in such manner as to engage the spurs 29-429 as the locomotive moves along the track.

Assuming the wire 10 to be in its uppermost position, as shown in Fig. 1, the op eration of the device is as follows: As a locomotive approaches the crossing, the projection 31 engages the spur 29 and moves it. forward causing the semaphore S to rotate and thereby bring the trolley wire 10 into alinement with the trolley wire 4, the arm being held against further rotation by the fork 15. The wire 10 carries with it in its downward motion the arm 8 which engages the fork 15. The spur 29 is at the same time carried by the motion of the chain 25 to a position over the sheave 24. Electrical connection is made to the wire 10 by means of the forks iii- 15 thus permitting the 10 comotive to receive power while crossing the highway. When the locomotive has moved the spur 29 to a aosition over the sheave 25L,

the coil sprin 2'4 elongates and permits the spur 29 to move downwardly over the sheave 24 sufficiently to permit the projection 31 to pass. The contraction of. the spring then restores the spur 29 to a position over the sheave 24.

IVhen the locomotive has passed the crossing, the projection 31 engages the spur 25) which is now in position over the sheave 24 and moves it to a position over the sheave 23, and thereby restores the arms 8-8, the wire 10 and the spur 29 to their original positions. The elongation of the spring 26 permits the projection 31 to pass, and its contraction restores the spur 29 to position. The position of the whole device is now such that it is ready for operation at the approach of another locomotive from either direction. If desired, signaling devices may be connected to the semaphores to serve to passers along the highway as a warning of the approach of a locomotive. Such a signaling device is shown at 30. The wire 10 when in its upper position is preferably insulated from the main trolley wire 4, so that there will be no danger of shock to persons in vehicles passing along the highway. This insulation may be accomplished in any preferred manner as, for instance, by constructing the oles 11 and 5-5 of wood or other non-cont ucting material.
