PATENT GILES S. MOORE, OF INDIANAPOLIS, INDIANA, ASSIGNOR TO TRO'LLEY SHOE-W'I-IEEL COMPANY, OF INDIANAPOLIS. INDIANA, A CORPORATION OF INDIANA.

TROLLEY WHEEL.

' Application filed May 31,

To all whom it may concern:

Be it known that I, GILES S. MOORE, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful, Improvements in Trolley Wheels, of which the following is a specification.

My said invention relates to a trolley and it is an object thereof to provide a structure in which a sliding contact shoe shall engage the wire during normal forward progress of the car carrying the same, while on rearward movement of the car a rotary device shall engage the wire. The advantages of a sliding contact shoe over the contact wheel during forward movement are well understood by those skilled in the art and it is understood also that a rotary wheel is better suited for rearward movement of the car. It is an object of my invention to provide a simple, strong and compact arrangement of parts for carrying out the operation above indicated such construction being inexpensive to manufacture and not liable to get out of order.

Referring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate similar parts,

Figure 1 is a side elevation of my devic with the trolley moving in aforward direction as indicated by the arrow,

Figure 2 is a similar elevation with the car moving rearwardly as indicated by the arrow in said figure, and

Figure 3 a section on line 33 of Figure 1.

In the drawings reference character 10 indicates a trolley wire of conventional form and 11 indicates a harp having forks 12 connected by a bolt or equivalent device 13. A bracket 14 is pivotally supported on the bolt, this bracket being capable of assuming the positions indicated respectively in F1gures 1 and 2. A stop 15 on the harp engages a side of the bracket to limit its movement in one direction and astop 16 on the bracket engages the upper side of a fork of the harp to limit its movement in the opposite direction. The bracket comprises an upstanding part which may consist of two separate members mounted on the bolt 13 or on some convenient bushing or the like surrounding the bolt and held together at the 1923, Serial No. 642,572.

top by another bolt 17. A preferred con struction as here shown has a cross member 18 integral with or rigidly united with the side members 14 and a hollow shoe 19 of sheet metal or the like resting on the part 18 and held in place thereon by the bolt 17 part of the shoe for convenience in placing the shoe.

Each of the parts 14 has a laterally projecting arm 21, said arms being joined together by a bolt22 provided with any suitable anti-friction or lubricating devices such as are wellknown in the art and said bolt serving as a journal for a trolley wheel 23. One flange of the trolley wheel is provided with a tooth 24 adapted to be engaged b a pawl 25 pivotally supported by ears 26 on the members 14. A spring 27 is located between the tail of the pawl and the adjacent member 14 for holding the dog in contact with the flange or flanges of the wheel 23.

It will be obvious to those skilled. in the art that various changes may be made in the details of construction of my device without departing from the scope of the invention and therefore I do not limit myself to what is shown in the drawings and described in the specification but only as indicated in the appended claims.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a trolley, a harp, a bracket pivoted thereon and movable into horizontal and vertical positions, a sliding shoe on the bracket engaging the trolley wire in one of said positions, a wheel on the bracket engaging the wire in the other position, and a pawl on the bracket adapted to engage a tooth on the Wheel to raise the shoe and the bracket on forward movement of the trolley, substantially as set forth.

2. In a trolley, a harp, a bracket pivoted thereon and movable into horizontal and vertical positions, a sliding shoe on the bracket engaging the trolley wire in one of said positions, a Wheel on the bracket engaging the wire in the other position, a pawl on the bracket adapted to engage a tooth on the wheel to raise the shoe and the bracket on forward movement of the trolley, a stop on the harp engaging a side of the bracket in one extreme position, and a stop on the bracket resting on the harp in the other extreme position, substantially as set forth.

3. In a trolley, a support, a pivot on the support, a bracket on the pivot movable into vertical and horizontal positions, a sliding contact shoe resting on a fiat face at the outer end of the bracket, arms extendin'g laterally of the bracket, and a Wheel carried by said arms, said wheel and said shoe being arranged for alternate engagement with the wire, substantially as set forth.

4:. In a trolley, a support, a pivot on the support, a bracket on the pivot movable into vertical and horizontal positions, a sliding contact shoe resting on flat faces at the outer ends of the side members of the bracket, arms extending laterally of the side members of the bracket, a wheel carried by said arms, and means to support said bracket in vertical positionwhile mov ing forward and in horizontal position While moving backward, substantially as set forth- 5. In a trolley, a support, a pivot on the support, a bracket on the pivot movable into vertical and horizontal positions, a sliding contact shoe resting on flat faces at the outer ends of the side members of the bracket said shoe having side flanges, a renewable wear plate on said shoe between said flanges, anda bolt passing through the bracket, the shoe and the plate for securing the parts together, substantially as set forth. a i

6. In a trolley, asupport, a pivot on the support, a bracket on the pivot movable into vertical and horizontal positions, a sliding contact shoe resting onflat faces at the outer end of the side members, arms extending laterally of the bracket, a wheel carcrLEs s. MOORE; [Ls] Witnesses:
