TROLLEY-POLE ATTACHlWENT.

Specification of Letters Patent.

latented July 30, 1907.

- Application filed December 22.1905. Serial No. 292,924.

To all whom it may concern:

Be it known that l, PATRICK FELIX DURoss, a citizen of the United States, and a resident of the city of New York, Flushing, borough of Queens, in the county ,of Queens and State of New York, have invented a new and Improved Trolley-Pole Attachment, of which thev following is a full, clear, and exact description.

The purpose of the invention is to provide a very simple, durable and effective trolley pole attachment, in which the guide fingers located at the sides of the trolley wheel and extending above the same will automatically pass all manner of overhead obstructions, and wherein said guide fingers may be purposely drawn from the wire at any time found desirable or necessary.

A further purpose of the invention is to so construct the guide fingers for the wire that the wire will be directed to the central portion of the groove in the trolley wheel, and will be prevented from accidentally leaving the same.

The invention consists in the novel construction and Combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a central side elevation ofthe trolley pole, the section being taken centrally and longitudinally through the fork; Fig. 2 is a plan view of the fork and parts carried thereby; Fig. 3 is a vertical transverse section taken practically on the line 3-3 of Fig. 1; and Fig. 4 is a perspective view of a cheek piece for the l wheel and the guide finger for the wire carried thereby.

A represents a trolley pole and B the fork therefor, and between the members of the said fork the usual trolley wheel 10 is mounted to turn on a spindle 11, which is carried through the members of the said fork at its upper or outer end, and the wheel l() does not turn directly upon the said spindle but on a sleeve 12 which is loosely mounted on the spindle, as is shown in Fig. 3. A cheek piece G is pivoted on the said spindle at each side of the said wheel 10 between the members of the fork as is also shown in Fig. 3; and each of these cheek pieces C is formed as is best shown in Fig. 4, wherein a segmental body section c is provided, the upper portion being curved; and the said body at its inner end portion is provided with a nose 13 extending at an inclination downward therefrom. A bifurcated ear 14 extends downward from the body where it connects with the said nose, and a similar ear 15 extends down from the forward lower portion of the said body, both of these ears 14 and 15 being provided with apertures 16. About centrally between the ears 14 and 15 a single ear 17 is carried down from the lower edge of the body, and in this central ear 17 an opening 18 is made, which loosely receives the spindle 11.

Each cheek piece just above the central ear 17 is provided at its upper edge with au upwardly-extending guide finger 19; and the inner or opposing faces 20 of these guide fingers 19 are more or less coneaved as is par ticularly shown in Fig. 3 and inclined from the top downward to the central portion of the trolley wheel 10, thus forming shoulders 21, which shoulders are located just beyond the peripheral side edges of the trolley wheel and overhang the said wheel. The shoulders of the fingers extending inwardly toward each other to such an extent that the distance between them is less than the width of the groove of the wheel. These inclined faces 2() of the guide fingers 19 serve to direct the wire to the central portion of the trolley wheel 10, and the shoulders 2l at the inner faces of the said guide fingers act to prevent the wire accidentally flying upward beyond the guide fingers.

The forward ears 15 of the cheek pieces C are connected by an arched connecting rod 22, shown in Figs. 1 and 2, and normally the nose 13 of each ofthe cheek pieces C rests `upon a cross bar 23 extending from one side of the fork to the other as is shown in Fig. 1, as the cheek pieces are of greatest weight at their inner or rear l portions, and at such time the guide fingers 19 extend upward in substantially vertical alinement with the center of the trolley wheel l0 as is also shown in'Fig. 1. A clip 24, of any suitable or approved construction is secured upon the fork B, back of the rear lower ends of the cheek pieces C, and the said clip at its lower portion carries a bar 25, located below the fork B; and on this bar, preferably at its center, a grooved friction pulley 26 is mounted to turn.

If for any reason it is desired to carry the guide fingers 19 forward, so as to take them away from Contact with any object overhead, it is simply necessary to pull down upon a rope 27, which is passed over the pulley 26 and is attached tothe connecting rod 22, since when such tension is applied to the rope 27 the cheek pieces will be made to rock on their bearings in a rearward and forward direction, thus if necessary bringing the guide fingers 19 to a horizontal position, or practically so.

The ends of a chain 28 are connected with the rear ears 14 of thecheek pieces, and the upper end of the conductors controlling rope 29 is connected with this chain, the chain being usually passed through aloop 29a formed at the upper end of the rope as is shown in Fig. 1. This rope 29 can extend down parallel with the rope 27 for shifting the cheek pieces.

In rainy weather water often runs down the controlling rope 29, rendering the use of said rope exceedingly uncomfortable and inconvenient at times, since it is frequently the cause of wetting the operators sleeves and other portions of his outer garments. This disagreeable experience is obviated by the employment of a Water conductor D, the body 30 of which conductor is preferably funnel-shaped as is shown in Fig. 1, and

is provided with a central tube 31 extending through beyond the top and the bottom; and the controlling rope Ais passed through this sleeve, and the body oi said conductor, after having been adjusted on said rope, is secured in adjusted position bya clamp or clip 32 of any approved pattern. At the lower end of the body 30 of the said conductor a spout 33 is provided, which conducts the water away from the rear platform and usually beyond the rear dash-board.

The upper end portions of the said guide ngers 19 are inclined in opposite directions at the side edges, practically meeting in a point at the top, and the lower portions of the Vsaid side edges are more or less concaved, so that the general shape of the said finger pieces is that of an arrow-head.

It will be observed that the action of the cheek pieces is automatic, since should the guide fingers come in Contact with any obstruction the rear portion othe cheek pieces will be elevated and the cheek pieces will assume a horizontal or forwardly-inclined posit-ion until the obstruction is passed, whereupon they will return to their normal position. It is evident that by the use of the rope 27 the lower rear portions ot the cheek pieces may be purposely elevated at will at any time.

Having thus described my invention, I claim as new, and desire Ato secure by Letters Patenu- 1. A trolley wheel, a support in which the wheel is mounted, cheek pieces connected together and mounted to rock on the spindle of the wheel, one at e'ach side thereof, each cheek piece being provided with an upwardly eX- tending and substantially centrally located guide nger, the guide fingers being inclined from the top downward and formed with inwardly projecting shoulders overhanging the wheel, and manually controlled means connected with tbe' ends ot' the cheek pieces for rocking the same.

2. A trolley wheel, a fork in which the wheel is mounted, cheek pieces pivotally mounted on opposite sides of the wheel and each provided with a guide nger projecting above the wheel, ropes connected with the ends of the cheek pieces, and means for limiting the downward movement of the rear ends of the cheek pieces.

3. A fork for a trolley wheel, a wheel mounted to revolve between the members of the said fork, a spindle on which the said wheel turns, segmental cheek pieces mounted to rock on the said spindle, one at each side'of the said wheel, said cheek pieces being provided with upwardly-extending centrally located guide fingers having pointed upper ends and their inner faces concaved and inclined downward in direction of the center' of the Wheel, forming shoulders above the periphery of the wheel, a

'flexible connection between the rear portions of the said cheek pieces, a stop for the r'ear portions of the cheek pieces and carried by the fork, a controlling rope attached to said exible connection and a rope connected with the lower' portions ot' the said cheek pieces, whereby to draw their rear ends upward and forward and carry the guide lingers to a substantially horizontal position when necessary.

4. A fork, a wheel mounted in the fork, cheek pieces mounted to rock on the spindle of the wheel and each provided with a guide finger projecting beyond the wheel, and r'opes connected with `the ends of the cheek pieces.

5. A fork, a wheel mounted in the fork, cheek pieces mounted on the spindle ot' the wheel and each provided with a guide linger projecting vbeyond the wheel, a stop on the fork with which the inner' ends of the cheek pieces engage, a pulley on the fork, and a rope connected with the outer' ends of the cheek pieces and passing over said pulley.

6. A fork, a wheel mounted in the fork, cheek pieces mounted on the spindle of the wheel, said cheek pieces being each provided with a central guide finger, depending ear's at its ends and a nose at one end, a bar connecting the ear-s at the forward ends of the cheek pieces, a bar between the members of the fork and with which the nose ot' cach cheek piece engages, a guide pulley on the fork, a rope secured to the bar connecting the ears of the cheek pieces andpassing over the guide pulley, a chain having its ends secured to the ears at the inner ends of the cheek pieces, and a rope secured to said chain.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
