TROLLEY.

Specification of Letters Patent.

Patented April 23, 1907.

Application filed June 906- serial 323,436.

, being disassociated in event of the trolleywheel jumping the trolley wire.

. The invention aims to provide a harp similar to the ordinary type of harp carried by the trolley poles of electrically operated cars, and in connection with the trolley-harp, I employ available means for preventing the harp from leaving the conductor or trolley wire in event of the trolley wheel being disconnected from or jumping the wire.

In constructing my improved harp, l have considered the possibility of interference by wire hangers, crossings, and overhead work that may tend to break and interfere with the positive operation of my improved. mechanism, therefore, I have constructed the harp, whereby a portion of the same may recede without breaking or injuring the overheadconstruction which supports a trolley wire. In this connection, the invention dispenses with the trouble and watchfulness on the art of a car operator heretofore necessitate by the construction of the trolley wheels and harps. To this end, I have devised a trolley-harp having spring-held arms which normally extend above the trolley wire.

The detailed construction of my im roved harp will be presently described an then specifically pointed out in the claims.

Referring to the drawing forming part of this specification, like numerals of reference desi nate similar parts in the several views, in w 'ch:

Figure 1 is a side elevation of my improved trolley harp, Fig. 2 is a plan of the same, Fig. 3 is a vertical sectional view taken on line x:z: of Fig. 1, and Fig. 1 is a longitudinal sectional view of a'portion of one of the side arms of my improved harp together with one of the yieldable fingers of the same.

My improved harp consists of a sleeve 1 adapted to fit upon the end of a trolley pole 2, said sleeve being secured thereon by a pin 3 or similarjfasteningimeans.,it The sleeve 1 carries two parallel arms 4 similar somewhat to any ordinary harp. Between these arms is mounted a transversely disposed pin 5, upon which a trolley wheel 6 is journalled, said wheel having a prolonged hub 7 normally held centrally of the pin 5 by springs 8, secured to the arms 4, as at 9.

The ends of the arms 4. are provided with angularly disposed extensions 10 and with sockets 11. In said sockets are loosely mounted the ends of rods 12, said rods being further supported intermediate their ends by springs 14. The springs 1 1 surround depending pins 15 carried by the rods 12, said pins extending through the extensions 10 and retained therein by cotter pins 16.

When the trolley wheel 6 is placed upon a trolley wire 17, the rods 12 extend upwardly at an angle upon each side of said wire, and ellectually prevent the lateral displacement of the harp. As the harp passes under cross over wires, or trolley boards, such as are arranged under bridges, the rods 12 re cede and are returned to their normal position by the springs 14, which rest upon the extensions 10. The arms 12 are independently arranged and independently supported by their respective rods 15 and springs 14, so that if an obstruction at one side of the trolley only is met with one of the arms only will be depressed, thereby leaving the other arm in position to protect the harp and wheel from lateral displacement. This is an important feature of the invention and adds materially to its e'l'l'iciency.

'Since a lateral movement of the trolley wheel 6 is possible by the construction herein shown and described, said wheel can readily adjust itself to a wire that may not be in di rect alignment with the pole 2.

The entire harp is constructed of strong and durable material especially the rods 12, which will be subjected to considerable wear and tear, by contacting with the wire 17 and its hangers or supports.

Such changes in the size, proportion and minor details of construction as are permissible by the appended claims may be resorted to without departing from the spirit and scope of the invention.

\Nhat I claim and desire to secure by Letters Patent, is

1. A trolley harp comprising a sleeve supported upon a trolley pole and with spaced arms extending from the forward end and I provided with longitudinal sockets interme above the line of the trolley wheel, and yieldable devices between said rods and the free ends of said arms.

2. In a device of the class described, a member having means for connection to a trolley pole and spaced longitudinal arms having sockets intermediate their ends and with apertures at their free ends, a trolley wheel journalled between said arms, rods bearing at one end loosely 1n sald sockets and extending at their free ends above the line of the trolley wheel, pins depending from said rods and extending through the apertures in said spaced arms, and springs operating between said rods and arms and maintaining said rods yieldably in their upward position. In testimony whereof I afliX my signature in the presence of two witnesses.
