SPECIFICATION forming part of Letters Patent No. 661,516, dated November 1 e, 1900.

Application filed March 21, 1900. serial No. 9,523. (No model.)

To (tZZ whom it may concern;

Be it known that I, HENRY S. GOUGHNOUR, of Johnstown, in the county of (Jambria and State of Pennsylvania, have invented a new and useful Improvement in Trolleys, (Case A,) of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,which form a part of this specification.

My invention has relation to certain new and useful improvements in trolleys, and is designed to provide means of improved character whereby when the trolley-wheel leaves the conductor from any cause the pole will automatically assume a position where it will not come in contact with and injure or be injured by span or guard wires or other overhead structures, together with means whereby the pole may be subsequently returned to its original position.

A further object is to provide a trolley-base of simple and efficient construction which shall have a minimum projection above the roof of the car, so as to permit the latter to pass under bridges and other low overhead structures.

\Vith these objects in view my invention consists in the novel construction and combination of parts, all as hereinafter described, and pointed out in the appended claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of my improved trolley. Fig. 2 is a plan view of the same. Fig. 3 is a detail View showing the spring and the means for holding the same in tension and for releasing the tension, and Fig. A is a detail view of the resetting device.

The letter A designates an arm or bracket which is swiveled to the roof of the car in any desired or usual manner, and B is the trolleypole, which is pivotally secured between the side portions of said bracket a short distance above its lower end.

0 is the spring which normally holds the trolley-pole in contact with the overhead conductor. This spring is coiled about one end portion of a rod D, whose opposite end portion is link-connected with the lower end of the pole, one end of the spring bearing against a head or stop on the end of the rod and its other end bearing against a slide E, in to which said rod extends through one end thereof. The slide E is seated between and guided by the side portions of the bracket A. On the rear end of the said slide is a catch projection F, which is normally engaged by a latch F, pivoted atfto a block F which is seated on the bracket A and which is formed with a lug or projectionf, to which is connected one end of a chain G, whose opposite end is connected to the trolley-pole a short distance above its pivot. In lieu of this chain I may employ a link or other equivalent connection. The block F is fulcrumed at its lower corner] and is held to its seat by a pin f whose end portions are seated in slots g of the bracket A and pressed by springs g H designates resetting-levers, which are pivoted at their lower end portions to opposite sides of the bracket A and are connected at their upper ends by a pivoted bail H.

I is a transverse rod which extends through longitudinal slots 7%; in the sides of the bracket A and which is formed with cranked end portions I, which are pivoted in the respective levers H. These levers normally lie in nearly flat positions down alongside the bracket A, as shown in full lines in Fig. 1, being returned to this position after operation by their own gravity. If desired, however, retractingsprings may be employed for this purpose.

P designates the usual guide-rope for the trolley-pole, one end being connected to the pole in the usual manner and the other end being connected to the bail H of the resetting-lever, the intermediate portion of the rope being designed to hang down over the back of the car in position to be readily reached. A separate rope may, however, be provided for the resetting-lever, if desired.

The operation is as follows: Under the normal running conditions the latch F is in engagement with the catch projection F of the slide E, and the spring C is thereby held under compression. hen, however, by any cause the trolley-wheel leaves the conductor, the pull on the chain G when the pole reaches or approaches a vertical position rocks the block F on its fulcrum and disengages the said latch. This releases the slide E, which is at once thrown toward the lower end of the pole by the spring 0, the latter thereby losing its tension. The pole now immediately drops to about the position shown in dotted lines in Fig. 1. The slide E is stopped by the rod I as the pole approaches this position, so that further drop of the pole by its pull on the rod D tends to compress the spring 0, and thereby cushion the impact of the pole.

To reset, a pull on that branch of the rope which is connected to the bail Hi raises the levers H, thereby causing the rod I to push backward against the slide E and force the latter back to its original position, where it is automatically caught and held by the pivoted latch F. Therod l by reason of its cranked ends exerts a push in a direct line upon the slide throughout its upward movement of the levers, and a very effective leverage is obtain ed for restoring com pression to the spring. The latch device being seated in the manner described remains in position to automatically engage the catch F, notwithstanding the fact that at the time the engagement is effected there is some tension in the chain G, which would otherwise tend to hold said latch in raised position. The describeddetails of said device are, however, not essential to my invention, since various forms of latch devices may be used. Nor do I wish to be limited in other respects to the mechanical details of construction and arrangement which I have herein shown and described, as these may be varied without departing from my invention as it is pointed out in the following claims.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is

1. In atrolley, the combination with a pivoted trolley-pole, of a spring for elevating the same, a slide forming a bearing for one end of said spring, a rod having a bearing for the opposite end of the spring, and connected to the said pole, a latch device for said slide, and a connection between the pole and said latch device for tripping the latter when the 'pole assumes a certain position.

means for restoring the compression in said spring.

3. In a trolley, the combination with a pivoted pole, and a spring for holding the pole in running position, of a slide forming a bearing for one end of said spring, a latch device for said slide, and a connection between the latch device and the pole for automatically tripping said latch.

4. In a trolley, the combination with a pivoted trolley-pole and its actuating-spring, of a slide forming a bearing for one end of said spring, a latch device for said slide, a connection between the latch device and the pole for automatically releasing said device when the pole assumes a certain position, a resetting-lever engaging the said slide, and means for actuating the said lever.

5. In a trolley of the character described, the combination with the pole, its actuatingspring, and a slide forming a bearing for one end of said spring, of a latch for engagement with said slide, a block to which said latch is pivoted and which is arranged to fulcrum at one of its edges, spring means for holding said block to its seat, and a connection between said block and the trolley-pole.

6. In a trolley of the class described, the combination with the pivoted pole, its actuating-spring, the slide forming a bearing for one end of the said spring, a latch for holding said slide with the spring under compression, and means for automatically releasing said latch when the spring assumes a certain position, of a resetting-lever engaging one end of the said slide, and means for actuating said lever.

'7. In a trolley, the combination of a swiveled bracket, a pole pivoted thereto, a spring seated in said bracket, a rod connected to the pole at one end and having a bearing for the distant end of the spring, a slide'on said rod having a bearing for the opposite end of the said spring, alatch for securing the said slide, means whereby said latch is released when the pole assumes a certain position, and means for restoring said slide to its original position after it has been released.

8. In a trolley-base, the combination with a swiveled bracket, apole pivoted thereto, an actuating-spring, for said pole, a slide forming a bearing for one end of the spring, and in which the spring is seated, means for holding said slide with the spring under compression, and forantomatically releasing the same when the pole assumes a certain position, of a resetting device engaging the said slide to move the same in one direction, and also forming a stop for limiting the movement of said slide in the opposite direction.

9. In a trolley, the combination with the bracket, and the slide mounted therein and forming a bearing for one end of the pole-actuating spring, of the connected resetting-levers pivoted to opposite sides of said bracket and the transverse rod seated in slots in said bracket and engaging one end of said slide, said rod having crankedend portions pivotally secured in said levers.

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

HENRY S. GOUGHNOUR.
