TROLLEY-POLE.

Application filed February 20, 1918.

To all whom it may concern:

Be it known that I EDGAR M. WAGES, a citizen of the United tates residing at Los Angeles in the count of 1210s Angeles and State of California, have invented certain new and useful Improvements in Trolley- Poles, of which the following is a specification.

This invention relates to trolley poles for use upon electric cars, having for its primary object to generally simplify and improve the construction and operation of devices of this character as well as to increase their efficiency.

A further object of the invention is to provide a trolley pole which is of such improved construction as to minimize the opportunity for the .wire engaging wheel becoming disengaged from the wire when rounding curves or striking obstructions in the wire. i

A further object of the invention is to provide a trolley pole which is capable of reel moving transversely of the car with which it is used, as well as longitudinally thereof, and which is equipped with means for maintaining the trolley wheel at all times properly engaged withthe feed wire.

With these objects in view, together with others which will appear as the description roceeds, the invention resides in the novel ormation, combination, and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings, and particularly pointed out in the claim.

In the drawings Figure l is a side elevation of a trolley pole constructed in accordance with the invention,

Fig. 2 is a vertical sectional view taken through one of the sections of the'improved telescopic pole, I I

Fig. 3 is an enlarged detail sectional view taken through the trolley pole,

Fig. 4 is a horizontal sectional view taken substantially upon line 44 of Fig. 2.

The improved pole comprises a pair of telescopic sections 6 and 7, the same being preferably rectangular in cross section, the section 6 being attached to the roof of the car and constituting the base member of the pole, while the section 7 is provided at its outer end with the usual grooved wheel 8 to engage the wire.

The base member 6 carries at its upper end a pair of spaced rollers 9, the extremi- Bpeclflcation of Letters Patent.

Patented J an. 18, 1921.

Serial No. 218,293.

section 7 may be readily moved inwardly or outwardly of the base section 6, the rollers 9--11 enabling this movement of the section to be performed with the least possible amount of friction, and the said rollers pro erly maintain the section 7 in position. he upper end of the section 6 is provided with a pair of hook members 12, to which are connected one end of contractile springs 13, the lower ends of the said springs being engaged with hooks 14 upon the lower end of the inner section 7. springs normally hold the section 7 extended so as to force the trolley wheel 8 into engagement with the wire sufficiently to maintain a proper contact. Undulations in the trolley will be compensated for by this particular arrangement.

Rockably mounted upon the car with which the pole is to be used is a frame 15.

These The supporting brackets 16 for this frame are arranged preferably in alinement longitudinally of the car, so that the frame 15 will be capable of oscillating transversely of the car. The base section 6 of the pole is seated at its lower end upon the frame, so that oscillation of the latter will be de livered to the pole. Theframe is provided with apair of spaced rods or supporting bars 17 which are engaged by forked members 18 depending from the sides of the base section 6. These forked members constitute bearings for the base section, and it is obconnected to hooks 21 projecting outwardly from the sides of the base section 6.

The springs 19 are so arranged as to normally hold the pole upright at right angles to the frame 15, and to maintain the latter in horizontal position. However, the frame is capable of oscillating freely, as is the pole capable of rocking either forwardly or rearwardly upon the supporting bars or rods 17.

Confined within the pole is a conductor Wire 23 which is connected at one end to the wheel 8, and may be led through the car to the motors thereof. It will be observed, particularly with reference to Fig. 2 of the drawing, that the wire 23 is loosely confined within the said pole, so as not to interfere with the operations of the latter, and yet sufiicient wire is provided to permit of the said pole being extended to its limitwithout affecting the electrical connection between the trolley wire and the car.

The base member 6 may be provided adjacent its outer end with eyes 24: to receive the ends of ropes or cords. It will be understood that ropes so connected to the pole will enable the operator to properly place the wheel 8 upon the wire.

By mounting the pole upon the oscillatable frame in the manner set forth, it is obvious that the said pole is capable of swinging forwardly or rearwardly oi the car, and is also capable of swinging; transversely of: the car, thus enabling the trolley wheel to prop erly follow the wire however devious may spect to a support and in a direction at right angles to the rocking action of said frame, rods carried by said supporting frame. hooks carried by said base and adapted to straddle said rods for holding said base upon said frame, hooks on opposite sides of said base, springs engaging said hoolcs in spaced relation to said base and secured iii their lower ends to a support for uorumlly maintaining said base in a vertical position.

In testimony whereof I ailix my signature in presence of two witnesses.
