APPARATUS FOR PREVENTING TROLLEY-WHEELS FROM LEAVlNG THE FEED-WIRE.

SPECIFICATION forming part of Letters Patent No. 703,786, dated July 1', 1902.

'Application filed March'3, 1902.

T0 aZZ whom it may concern.-

Be it known that I, GEORGE W. HAMMOND, a citizen of the United States, residing in the city and county of Philadelphia,State of Pennsylvania, have invented new and useful Im provernents in Apparatus for- Preventing Trolley-Wheels from Leaving the Feed-Wire, of which the following is a specification.

My invention relates to improvements in apparatus for preventing trolley-wheels from leaving the feed-wire and it consists of means whereby the jaws that prevent said wheels leaving the feed-wire may easily pass across; wire or similar object in the path thereof.

It further consists of novel details of construction, all as will be hereinafter set forth.

Figure 1 represents a perspective View of the apparatus. Fig. 2 represents an end elevation of the apparatus. Fig. 3 represents a plan view of the parts seen in Fig. 1. Fig. 4

represents a side elevation of certain of the parts seen in Fig. 1.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates the upper portion of a trolley-pole, which latter has journaled therein the trolley-wheel 2, which is in contact with the feed-wire 3, so as to convey electricity from the latter to a motor.

The wheel 2 is located between the members 4, which latter in the present instance are integral with the trolley-pole, it being noted that the forward portions 5 of said members 4' are inclined, as best seen in Figs. 1 and at, and the object of which is to elevate a cross-wire, &c., 6, which may lie in the path between the wire 3 and the lower extremity of the portion 5-, (see Fig. 4,) so as to lift said wire 6 and bring the. same to the ,wheel 2,

which latter will then'pass under the wire 6 when the trolley-pole is moving in the direction indicated by the arrow at in Fig. 1.

The direction-of movement of that portion of the wire 6 which comes in contact with the portions 5 of the members a is indicated by the arrow 1) in Fig. at and illustrates how said wire 6 is caused to pass over the wheel 2 when the trolley-pole 1 is in motion.

The rear, portions 7 of the members 4 are Serial No, 96,355. (No model.)

and 3, for a purpose to be hereinafter described.

Journaled, as at 9, in -the upper portions of 5'5 thetrolley-pole 1 are the collars 10, to each of which is pivoted, as at 11, the arms 12, which'latter are provided-with inwardly-projecting members 13, whose inner ends 14 meet at a point above the trolley-wheel 2 and are normally retained in contact with each other by springs 15, as best seen in Fig. 2, it being noted that one of said springs is seen in Fig.

[1 and indicated by dotted lines in order not to .concealfrom view the car 16, to which one of the arms 12 is pivoted. I

17 designates a cross-wire (see Figs. 1 and 4) located above the. Wire 3, it being noted that the cross-wire 6 is'located below the wire 3. The object in locating one of said crosswires above and the other cross wire below the wire 3 is to illustrate the manner inwhich the trolley-wheel 2 may be made to pass a cross-wire, 850., located either above or below the feed-wire" 3.

The operation is as follows: \Vhen the trolley-pole 1 is moving in the direction indicated by the arrow at in Fig. 1 and the trolley-wheel 2 is brought in contact with a cross-wire-for instance, the'wire ,17- -it is apparent that the 8'0 arms 12are caused'to turn on their pivots 9 and vmove in the direction indicated by the arrow c' in Fig.1 and caused to occupy the position seenin full lines in Fig. 4., it being noted that when the arms 12 are in said position their innervertical faces 18 (see Fig. 2) have been brought in contact with the flaring faces 1-9 of the rear portions? of the members 4: and are thus caused to turn on their pivots 11, whereby the inwardly-projecting clear the wire3 (seealso Fig. itand pass un- 5 der the cross-wire 17, after which thearms 12 are returned totheir normal positions, as seen in Figs. 1 and 2, by the springs 15, which latter yield when the arms 12 are acted upon The arms 12 are reby the flaring faces 19.

turned from the inclined position (seen in Fig. 4) to their normal or vertical positions, as seen in Figs. 1 and 2, by the springs 20. Any suitable meansfor instance,lugs 21 and 22may be employed to prevent said springs 20 from carrying the arms 12 beyond the desired point, it being understood that the hubs of the arms 12 are each provided with a l'ug21,

which moves in unison with said hubs, and that the portions 5 of the members 4 are each provided with a 'lug'2i, rigid with said portion 5 and against which the lugs 20 abut when the arms 12 are in their normal positions.

It Will be apparent that various changes may be made by those skilled in the art which will come Within the spirit of my invention, and I do not, therefore, desire to be limited in everyinstance to the exact construction herein shown and described.

Having thus described my invention,.what I claim as new, and desire to secure by Letters Patent, is-

1. In a device of the character named, a trolley-pole, forwardlyprojecting members attached thereto,rearwardly-projectin g members on said pole, collars journaled upon said pole, arms pivotally mounted upon said collars adapted to contact with said rearwardlyprojecting members, inwardly projecting. members upon said arms, and means for holding the latter in position with respect to each other.

2. In a device of the character named, a trolley-pole, forwardly-projecting members attached thereto,rearwardly-projectingmembers on said pole,vcollars j ournaled upon said pole,arms pivotally mounted upon said collars adapted to-cont-act with said rearwardlyprojecting members, inwardly projecting members upon said arms, means for holding said inwardly-projecting members in j uxtaposition, and means for permitting said arms and members to have a yielding rotary movement.

3. In a device of the character named, a"

trolley-pole, forwardly projecting members attached thereto,rearwardlysprojectin g mem- Ward portions and upwardly-flaring rear portions, collars journaled upon said pole, arms pivotally mounted upon said collars adapted to contact with said rearwardly-projecting members, inwardly-projecting members upon said arms, springs'for holding said members in juxtaposition, and means for permitting said armsand members to rotate with respect to said trolley-poles.

attached thereto,rearWardly-proj ectin g members on said pole, collars rotatably mounted I upon said pole, arms pivotally mounted upon said collars adapted to contact with said rearwardly projecting members, inwardly projecting members on said arms, and means for holding said members in position relative to.
