SPECIFICATION forming part of Letters Patent No. 783,228, dated Febraary 21, 1905.

Application filed August 11, 1904. Serial No. 220,361.

1'0 a, whom it may concern:

Be it known that I, OHARLns J. SosnN- HEIMER, a resident of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Trolleys; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to trolleys, and has special reference to such a form of trolley in which the wheel will be kept in contact with the wire at all times desired and will be prevented from jumping off while the car is going around curves, &c.'

The object of my invention is to provide a simple, cheap, and effective trolley for this purpose, as well as one which will be strong and durable and one in which no parts are in such position as would be liable to catch on the wire, &c.

My invention consists, generally stated, in the novel arrangement, construction, and combination of parts, as hereinafter more specifically set forth and described, and particularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains to construct and use my improved trolley, I will describe the same more fully, referring to the accompanying drawings, in Which- Figure 1 is a side elevation of the upper end of a trolley, showing my invention applied thereto. Fig. 2 is a rear elevation of the same. Fig. 3 is a top view of the trolley-pole socket. Fig. l is a bottom plan view of the harp. Fig. 5 is a detail view, partly in section, of the upper end of the socket and joint connection on the harp for engaging with said socket.

Like symbols herein indicate like parts in each of the figures of the drawings.

As illustrated in the drawings, 1 represents the trolley-pole socket-piece, which is adapted to be connected at the lower end to the trolleypole, (not shown,) while its upper end 2 is provided with the enlargement or head 2 thereon, having the vertical opening 3 through the same to receive the vertical pin t on the lower end 5 of the harp 5 in forming the swiveled joint 5. This harp 5 extends upwardly at about an angle of forty-five degrees (45 from the opening 3 and is provided with the sides 6 thereon for supporting the spindle or axle 7 which passes through openings 7' in said sides 6 and has the trolley-wheel 8 loosely mounted around the same, while such axle 7 is held in place by means of the cotters 8, passing down said sides 6 and axle 7.

Extending up from top 2 of the enlargement or head 2 and on each side of the opening 3 in said enlargement are the projections 9, which are provided with the stop faces or shoulders 9 on each end thereof and formed at an angle to said opening 3, while extending out from and on each side of the pin 4 on the lower end of said harp 5 are the projecting front and rear jaws 10, and such jaws are provided with the stop-faces 10 thereon for engaging with the stop-faces 9 on the projections 9. The jaws 10 are alsoprovided with the curved lower bearing-faces 10" thereon for engaging with and conforming to the oval-shaped bearing-faces 10*, formed on the top 2 of said enlargement or head 2 around said opening 3 and between the stop-faces 9 on the said projections 9 in forming the oval bearing-joint 9. The lower end 4 of the pin 4 in forming the swiveled joint 5 extends through the opening 3 in the enlargement or head 2, so that it can he held in place within said opening 3 bymeans of a cotter or pin 11, which passes through said lower end 4c, while a washer 11 is placed around said lower end 4, so as to fit between said cotter 11 and the lower face 3 of said enlargement or head. A bracket 12 extends from the lower face 3 of said enlargement or head 2 to the socket-piece 1, and such bracket is preferably formed as part of said enlargement and socketpiece, so as to fit over the lower end i of said pin 4. and prevent the trolley-wire 8 from being caught by said pin 4 at any time.

When my improved trolley has had its parts assembled and in use with the trolley-wheel 8 in contact with the wire 8, the opening 3 in the enlargement or head 2 on the socket-piece 1 and carrying the pin 4 therein on the harp 5 will be in substantially a perpendicular plane, so that such harp 5, carrying the said wheel 8, will always remain at about an angle of forty-five degrees to said opening 3 and pin 4:, which will allow said wheel 8 to continually follow the wire 8 and prevent such wheel from jumping off or leaving said wire. In passing around curves in said wire 8 the pin 4 will turn in said opening 3, so as to allow the trolley-wheel 8 to conform to the curve in the wire 8, and the curved faces 10 and the jaws 10 will travel along the oval-shaped faces 10 on said enlargement or head 2 in order to allow the stop-faces 10 on the jaws 10 to strike against the stop-faces 9 on the projections 9. By the engagement of the stop-faces 10 on the jaws 10 with the stop-faces 9 on the projections 9 the trolley-wheel 8 will beheld in line with the wire 8 in all ordinary curves of said wire and in either direction of from right to left, while the oval bearing-joint 9, formed by the bearing- faces 10 and 10 on the jaws 10 and enlargement 2, respectively, will permit the trolleywheel 8 to work and turn freely and quickly by means of the harp 5, with its pin 4: in the socket 3, through all degrees of the curves in said wire. It will thus be obvious that in the use of my improved trolley the wheel can be pulled from the wire by means of the usual rope quickly and conveniently without any complicated or projecting parts to interfere with the same, as in the case with the ordinary class of these devices, and in case of the transfer of the trolley from one wire to another the jaws by engaging with the stops around the swivel-joint will prevent the harp and wheel from turning too far, so that the wheel can be easily and quickly adjusted to the other wire. It will also be seen that the car carrying the trolley can be run backward without danger of tearing down the feed-wire or guide-wires in case thetrolley should leave the feed-wire by reason of the lack of exposed or projecting parts to catch onto such wires and by reason of the wheel being able to conform and adjust itself to the curves in the feed-wire, thereby forming an alinement therewith, so that it will be evident that such wire will not strike against the sides of the wheel, which form the trough or groove for such wire, and thereby'causing great saving in the wear of said wheel and wire.

Various modifications and changes in the design and construction of the device may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

W hat I claim as my invention, and desire to secure, by Letters Patent, is-

1. A trolley comprising a trolley-pole having curved faces on its upper end, a trolleywheel, a harp for carrying said wheel and adapted to be connectd to said pole by a swiveled joint, vertically-extending stops on said pole, and projections on said harp for engaging with said stops to limit the revolving movement of said harp and wheel by said joint, said harp-stops having curved faces on their lower ends for engaging with the curved faces on said pole to form an oval bearing-joint.
