G. G. LYNDE. TROLLEY FINDER.

".No.'542,591. Patented July 9, 1895] UNITED STATES 7 PATENT OFFICE.

CHARLES o. LYNDE, or BUFFALO, NEW YORK.

TROLLEY-FINDER.

' 1 SPECIFICATION forming part of Letters Patent No. 542,591, dated July 9, I895. Application filed November 28,1894. Serial No. 530,228. (No model.)

To all uhom it may concern.

Be it known that I, CHARLES C. LYNDE, a citizen of the United States, residing at the city of Buifalo,in the county of Erie and State of New York,have invented certain new and useful Improvements in Trolley-Finders; and

prevent the trolley-pole from springing above the trolley-wire and colliding with the cross supporting-wires in the event of the trolley-wheel becoming accidentally disengaged while the car is in motion.

Myinvention consists of a certain improved construction and arrangement of parts connected to and operating with the trolley-pole, all of which will be more fully hereinafter described, and pointed out in the claims.

In the drawings, Figure l is a front elevation of my improved device, showing the trolley-wheel in engagement with the trolley-wire.

Fig. 2 ma side elevation of same. Fig. 3 is a top plan view of same, showing the trolleywheel disengaged from the trolley-wire and the wheel and its pole held under the wire. Fig. 4 is an enlarged detached View of the clamp. Fig. 5 is a sectional view of Fig. 4, taken in the line :0 m. Fig. 6 is a similar view taken in theline yy, and Fig. 7 is a side view of Fig. 4.

Referring to the drawings, A is the trolleywheel, journaled in the upper bifurcated end of the trolley-pole B, and E is the trolley-wire.

My improved device, which consists of a stiff wire frame pivoted to the trolley-pole B, is constructed as follows:

O O are two arms located on either side of the trolley-pole B and parallel therewith. A

loop on, having upper cross-bar M and lower a a are loops or sockets upon the side arms 0 0, above and beyond whichare the diverging arms 0' 0', connected at their upper ends by the crosspiece h, which curves downwardly and is depressed at its center, as shown.

E E are rubber rings which encircle the cross-piece h at its outer ends and serve as guards to prevent the trolley-wire from slipping off the upper part of the frame.

G is a strengthening-brace in the form of a loop attached at the points b b on the under side of the diverging arms OO' of the frame. This loop G, however, is not always essential and may be omitted if the frame is strong enough without it.

A clamp composed of the upper part D and the lower part-D is rigidly secured to the trolley-pole B by the bolts J. The lower part D of the clampis provided with the integral trunnions K K, adapted for loose'engagement with the loops or sockets a a upon the frame, which is by this means pivoted to the trolleypole B. A cord L is attached to the lower end of the frame by means of which the frame is manipulated.

My improved device, just described, operates as follows: When the trolley-WheelA becomes accidentally disengaged from the trolley-wire E the trolley-pole B is forced npwardl y and the cross-piece h of the wire frame strikes the trolley-wire E, thus preventing any further upward movement of the trolley-pole B, as clearly shown in Fig. 3. The trolleycord L is then pulled down, carrying with it the lower part of the wire frame below its pivot point, its movementbeing limited by the cross-bar M of theloop m at its lower end. This movement causes the upper part of the wire frame above its pivot-frame to be elevated, throwing the cross-piece it against the trolley-wire E, thus raising it a short distance above the trolley-wheel A, and on releasing the cord L the trolley-wheelsprings up in contact with the trolley-wire. When the trolleywheel Abecomes disengaged from the trolleywire E, the cross-bar C of the loop 1% comes in, contact with the pole B and holds the frame in the position shown in Fig. 3. When the trolley-wheel is to be reserved in position upon the trolley-wire, myimproved frame.

makes this operation simple and easy by guiding the wire directly to the groove in the wheel.

I claim 1. Atrolley-guide consisting of a frame centrally pivoted to the trolley-pole, its lower portion having a loop encircling the trolleypole to limit its swinging movement and its upper swinging portion having a cross-piece adapted for contact with the lower side of the trolley-wire substantially as and for the purpose stated.

2. A trolley-guide consisting of a frame centrally pivoted to the trolley-wire, a clamp adsigned my name to this specification in the justable upon the trolley-pole and upon which the pivot for the frame is located, the lower portion of the frame having a loop encircling the trolley-pole to limit its swinging movement and its upper swinging portion having a cross-piece adapted for contact with the curved cross-piece h, and the clamp l) D adjustably secured to the trolley-pole B and having the trunnions K, K, adapted for loose engagement with the sockets a, a, on the frame all combined and operating substantially as and for the purpose stated.

In testimony whereof I have hereunto presence of two subscribing witnesses.

CHARLES C. LYNDE.
