TROLLEY-POLE SUPPORT.

Specification of Letters Patent.

Application filed July 2, 1910. Serial No. 570,190.

and it consists in the novel details of construction more fully set forth in the specification and pointed out in the claim.

In the drawings, Figure 1 is a side elevation of a car-roof showing my invention applied; Fig. 2 is a top plan of the anchor and pole, the latter being broken; Fig. 3 is a vertical section on the line 8-3 of Fig. 2, parts being in elevation; Fig. at is a horizontal section on the line 4 1 of Fig. 8; and Fig. 5 is a view of the socket-wall of the base-plate, looking in the direction of the gap in said wall.

The object of my invention is to construct a trolley pole anchor which will permit of rotation of the base of the pole with a view of reversing the direction of the pole when the car is ready to make a return trip.

A further object is to provide an anchor which will yieldingly lock the pole, once the same has been set in proper position to effect engagement between the trolley and the trolley-wire.

The advantages of the invention will be readily apparent from a detailed description thereof which is as follows Referring to the drawings, O represents a portion of a conventional trolley car to the roof of which the device is secured.

Carried on the roof is a base-plate 1 in the.

center of which is formed a socket a bound ed by the annular wall 2 in which is formed a gap 1) bounded by outwardly converging sides 0. At the center of the gap is pivotally mounted about a spindle 8, an oscillating pawl 4: tapering inwardly or toward the center of the socket. In its normal po sition the axis of the pawl is substantially on the radius of the circles defining the bounding faces of the wall 2, being main tained in said position by the free ends of the

flexed springs

5, 5, engaging the side faces of the pawl, the fixed ends of the springs being secured to the outer peripheral face of the wall 2 on each side of the gap 5.

Projecting from the center of the socket ais a stud or spindle 6 which passes centrally and loosely through a gear-wheel 7 formed with or carried at, the bottom of a bearing or supporting plate 8 to which the pole is directly secured. The gear wheel 7 fits loosely in the. socket a, the teeth thereof being engaged by the oscillating pawl 4, the

springs

5, 5, whereof allow the pawl to yield in either direction, depending on the direction in which the plate 8 and its gear-wheel are turned. The upper end of the stud 6 is screw-threaded to receive a nut 11. by which the plate 8 is held thereon against accidental displacement. The sides of the plate 8 are provided with arms or

lugs

9, 9, in which the terminals of the cylindrical rocker-bar 10 are mounted, the central portion of the bar having secured thereto a collar 10. To eye-

bolts

11, 11, projecting in opposite directions from the collar 10 of the rocker bar, are secured the adjacent ends of con tracting

springs

12, 12, the opposite ends of the springs being secured to eye-bolts 11 on bearing plate 8. From the collar 10 of the rocker-bar 10 projects upwardly an elongated socket 13 forming the lower section of an extensible trolley-pole 14 which is secured in position when adjusted to the proper length, by a set-screw 15.

The forks 16 of the pole carry between them the elongated spindle-like trolley 17, very commonly used by traction companies.

When the car reaches the end of its journey in one direction, the conductor or motorman seizes the cable m, pulls the trolley away from the wire w. He then draws on the cable so as to rotate the pole, together with the plate 8 and its gear-wheel 7 about the axis of the stud 6, it being immaterial (since the pawl 4 yields either way) whether the rotation of the parts be in one direction or the other. As rotation is thus imparted to the gear-wheel 7, the pawl 4t readily yields to allow the teeth of the wheel to pass by; and when the pole has been swung around to reverse position to enable the car to make a return trip, the cable is released, whereupon the proper spring 12 will Patented Oct. 31, 1911.

force the pole upward, effecting rengagement of the trolley with the line wire 10. The pawl t being permanently between the teeth of the wheel 7, prevents accidental excessive rotation of the plate 8, that is to say, a rotation which would cause the trolley to jump the wire, but yet always permitting (by reason of the yielding character of the springs 5, 5) that limited oscillation of the plate and gear-wheel to allow the pole and its trolley-pole to conform themselves to the various curvatures of a line-wire which may prevail on a given road. By having a pair of

springs

12, 12, (one spring on each side of the rockerbar 10) the trolley is kept under better control, the springs acting conjointly to maintain the pole in proper engagement with the wire. Of course, the active spring will always be the one to which the greater stretch has been imparted for an inclination of the pole in a given direction, such inclination elevating one of the eye-bolts 11 secured to the rocker-bar 10, and depressing the opposite eyebolt- (Fig. By having two springs 12, the pole may be tilted in either direction indiscriminately.

Having described my invention, what I claim is In combination with a plate secured to a car-roof, an annular wall projecting from said plate and forming a socket, said wall having a gap bounded by outwardly tapering sides, a pawl pivotally mounted at the center of the gap and pointing inwardly toward the socket, a central stud in the socket, a plate provided with a gear-wheel and passed loosely over the stud, the gearwheel freely rotating in the socket and engaging the pawl, flexed yielding springs secured to the socket walls on either side of the gap and having free ends engaging the side faces of the pawl, a spring-controlled rocker-bar mounted on the plate on the side opposite the gear-wheel, and a trolley-pole secured to the rocker-bar, substantially as set forth.

In testimony whereof I affix my signature, in presence of two witnesses,
