TROLLEY- GUARD.

Specification of Letters Patent.

Application filed February 3, 1913.

Patented Nov. 25, 1913. Serial No. 746,077.

To all whom it may concern Be it known that I, MAURO GUARIGLIA, a non-citizen of the United States, residing at Morgantown, in the county of Monongalia and State of West Virginia, have invented certain new and useful Improvements in Trolley-Guards, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in trolleys or electric railway cars. the object of the invention being to provide an improved means for securing trolley wheels against displacement on the line wire, while the car is in motion.

Another object of the invention is to provide a device of this character which will possess advantages in points of efliciency and durability, is inexpensive of manufacture and at the same time'is simple in construction and operation.

-With the above and other objects in view, the invention consists in the novel features of construction and the combination and arrangement of parts hereinafter more fully described, pointed out in the claims and shown in the accompanying drawings, in which- Figure 1 is a side elevation; Fig. 2 is a vertical sectional view; Fig. 3 is a top plan view; Fig. 4 is a detail plan view of the upper end of the arm; Fig. 5 is a front elevation; Fig. 6 is a detail perspective view of one of the retaining arms; Fig. 7 is a detail perspective view of one of the actuating bars; and Fig. 8 is a front elevation of the inner ends of the retaining arms.

Referring more particularly. to the drawings, 1 indicates the usual trolley pole having the wire engaging trolley wheel 2 mounted upon the outer end thereof and adapted for normal engagement with the wire 3. Mounted upon the pole 1 adjacent the outer end thereof is a sleeve 4 which is provided with a longitudinal opening 5 and arranged upon each side of the opening 5 are the spaced ears 6. Arranged within the ears are the bolts 7 upon which are mounted the winged nuts 8 whereby the sleeve 4 may be readily applied or removed from the pole.

Projecting outwardly and upwardly from the sleeve 4 is an integrally formed curvedv arm 9. The outer end of the arm 9 curves upwardly as shown at 10 and is provided with an enlarged upper end 11 having a flat upper surface as shown at 12, upon which is mounted the plate 13, said plate being secured thereto in any suitable manner. The upper end of the arm 9 is securely braced and held in spaced relation with the outer end of the trolley pole by means of the spaced parallel bracing members 14 integrally formed with the arm and projecting forwardly and secured to the outer end of the t-rolleypole as shown at 15.

Hingedly secured to the front side of the plate 13 is the guard member 16, said guard comprising the spaced side walls 17 which are substantially triangular in shape and integrally connected at one end by means of the transverse member 18. .The side walls 17 of the guard member are provided at their ends with outwardly projecting flanges 18 having an opening 19 formed therein. Secured within the opening 19 are the actuating cords 20 which are secured as shown at 21 to the main cord 22. The side walls 17 of the guard member are provided with the transverse alined openings 23 and secured to the outer face of the side walls 17 are the resilient angular arms 24, the horizontal portions of which project through the openings 23 and are arranged above the trolley wire to prevent the removal thereof from the guard. The inner ends of the arms 24 are provided with the inwardly beveled portions 25 so that when the wire 3 is engaged thereby, the inner ends of the arms may be readily separated to permit the wire to pass into the guard member. The plate 13 is provided upon its longitudinal edges with the threaded openings 26 which are arranged at diametrically opposite points and are adapted to receive the reduced threaded ends 27 of the tapering bars 28. The bars 28 are disposed at an angle with respect to the plate 13 and the upper ends thereof are arranged within the recesses 29 formed within the inner faces of the arms 24 so that the bars 28 are arranged between the arms and the side walls of the guard.

A coil spring 30 is arranged between the plate 13 and the transverse piece 18 which normally retains the guard member in the guard member.

position shown in 'Fig. 2, so that the same will normally retain the trolley wire 8 in engagement with the wheel 2.

In the practical operation of my device, it will be apparent that in Fig. 2, the same is shown in its normal position. In order to release the wire, the cord 22 is pulled downwardly which in turn will move the guard member downwardly toward the plate 23 and upon the downward movement of the guard member, the bars 28 will pass 7 upwardly between the arms 24: and the side walls of the guard member, separating the outer ends of the arms and allowing the wireS to pass out of the open end of'the Upon releasing the cord 22, the guard member 16 will pass upwardly, the wire 3 striking the beveled portions 25 and separating the arms 24 sufiiciently to allow the wire to pass into the open end of the guard member and be disposed beneath the outer ends of the arms 24:, thus retaining the wire in engagement with the trolley wheel 2. It will be apparent that upon releasing the cord 22, the spring 30, which has been placed under tension by the downward movement of the guard 16 will return the guard member to its normal position.

From the above description taken in connection with the accompanying drawings, it will be readily apparent that I have provided a simple and durable devicewhereby the trolley wheel will be securely held against accidental displacement on the line wire while the car is in motion. It will also be apparent that the device in itself is extremely simple in construction, eflicient and durable in its operation and can be manufactured at a comparatively low cost.

While I have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction and in the proportion may be resorted to for successfully carrying my invention into practice, without sacrificing any of the novel features or departing from the scope of the appended claims.

7 What I claim is 1. The combination with a trolley pole and wheel, of an open ended guard member adapted to receive the trolley wire, angular arms carried by the guard and normally closing the open end thereof to retain the wire into engagement with the wheel, tapering bars adapted to engage and actuate the arms upon the downward movement of the guard to release the wire and means for returning the guard to its normal po- SItlOII.

-2. The combination with a trolley pole and wheel, of a sleeve removably mounted upon the pole, a curved arm integrally formed with the sleeve, an open ended guard member hingedly secured to the upper end of the arm and adapted to receive the trolley wire, means carried by the guard for normally retaining the wire in engagement with the trolley wheel, means actuated by the downward movement of the guard for releasing said wire, and means for returning the guard to its normal position.
