TROLLEY-GUARD.

SPECIFICATION forming part of Letters Patent No. 716,477, dated December 23, 1902.

Application filed July 10,1901. Renewed October 24,1902. s'eriaillo.123,667. (N0 model.)

To all 1072,0712, it may concern:

Be it known that I, POLADORE H. REED, a citizen of the United States, residing at 1&9 Paterson avenue, city of Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in 'lrolley-Guards, of which the following is a specification, reference being bad therein to the accompanying drawings.

The main object of my invention is to prevent the trolley from leaving the wire in turning a corner or in passing under guide-wires, thus avoiding the damage that frequently is caused to trolleyavires where the overhead system is in use.

Another object is to provide a device that will be simple in construction, durable, and cheap.

Referring to the accompanying drawings, which form a part of this specification, and in which similar letters of reference indicate like parts, Figure l is a side view of my device applied. Fig. 2 is an edge or front view of the same. Fig. 3 is a side view showing guide-rollers or split pulleys forced down and opened to allow suspenders to pass, and Fig. 4 is an edge View (part) of split-pulley guiderollers opened.

A is reference-letter of the device.

The frame 13 may be of the ordinary or any other suitable construction, having the stem or log B, adapted to be secured to the pole, and the contact wheel or pulley O, mounted in the harp or frame, to rotate on the pivotal bolt 0, which is secured in the harp by the button-head nut 0 My invention consists of a split pulley or guide-rollers D, mounted on, the studs H, which pass through the metal ferrules or bushes D D in the split pulley or rollers D D. The studs H pass through openings in the top of spring side arms E E. The arms E E are at their lower ends pivotallysecured on the pivotal bolt 0. A bolt K is passed through the lower portion of the frame B and is secured therein by the nut K. Strong wire springs F F, having coils or loops F at their lower ends, are held and secured by the bolt K, which passes through said loops. Thence said springs F F pass into the opening, one on each side of the frame, around the bolt 0 inside of the harp and then upwardly on the outside of the spring side arms and through openings in the outer ends of the studs H, the heads of which are countersunk in the hard-rubber split pulley or rollers D D. The washers H H are mounted on the studs H H outside of the spring side arms E E and inside of the wire springs F F. Plus a a are passed through the frame or harp, near the top thereof, and project through the same to form a stop to limit the upward movement of the arms E E.

The operation of my device is shown in the drawings, in which Figs. 1 and 2 show the device with my invention applied in proper position, A being the trolley-wire in contact with the groove of the contact-wheel C and my split pulley or rubber rollers D, which are cone-shaped, being held together in contact by means of the spring-arms E and the tension-springs F, the split-pulley device be ing above the contact-wheel C. The split pulley or cone-shaped rubber rollers D open, as is shown in an exaggerated manner in Fig. at, and pass over the trolley-wire A when the conductor by guiding the pole gets the de vice under the trolley-wire, when the usual spring of the trolley-pole and the trolleywire cause the split pulley to open, as is shown in Fig. 3, which illustrates the position of the split pulley forced down and beginning to open to pass the trolley-wire or any bracket or suspending device A, which may cross or project above the trolley-wire A.

In Fig. 3, A is another view of the trolleywire shown in the position it would be when beginning to open the split pulley or coneshaped rubber guide-rollers.

The stop-pins a a limit the movement of the spring side arms E E, the springs F con1- ing in contact with said stop-pins, so that the guide-arms can go upwardly no farther than is shown in Fig. 1; but when in the progress of the car the trolley comes to a corner or to any other place where there are cross-Wires, brackets, suspending devices, or guy-wires the split pulley or cone-shaped rubber rollers D D will meet said obstructions, brackets, cross-wires, &c., at an angle, so as to cause the spring-arms E to be pressed downwardly without causing the contact-wheel C of the trolley to leave the wire, and the split pulley being pressed down forms a pulley directly behind the contact-wheel C and prevents the trolley contact-wheel C from leaving the trolley-wire, and after the split pulley has opened sufficiently to pass said bracket or other obstruction it is forced upwardly by the springs F and the spring side arms E until it is again in the position shown in Figs. 1 and 2.

In practice my device has shown it to be next to impossible for the trolley to leave the wire, as my device yields sufficiently when it meets an obstacle to enable it to pass. It serves to keep the trolley proper on the wire and is adjusted so as to open or separate when it meetsthe obstacle and to immediately fly up to its normal position when in operation, as shown in Fig. l.

Withthis description of myinvention,what I claim is 1. In a trolley-guard, the combination with the trolley-harp, the stud mounted therein and the main contact-pulley mounted to rotate on said stud, of two upwardly-extending spring-arms pivotally secured at their lower ends to said stud, one on each side of the said pulley and inside of the trolley-harp, two short studssecured to the upper ends of said spring-armsone on the inner face of each, a split pulley consisting of two independent conical-shaped hard-rubber rollers, each half mounted and adapted to rotate upon one of said short studs and to be kept in contact with each other by the tension of said springarms, a spring connecting each of said springarms with the trolley-harp and adapted to keep said split pulley in contact with the upper side of the trolley-wire, and stops to limit the movement of said spring-arms, substantially as set forth.

2. In a trolley-guard, the harp, the stud mounted therein and the trolley-wheel mounted to rotate on said stud, in combination with two spring-arms pivotally secured at their lower ends to said stud, inside of the harp, one on each side of the trolley-wheel, a short stud mounted in the upper end of each of said spring-arms, a conical-shaped hard-rubher roller mounted to rotate on each of said short studs, means to force the outer ends of said spring-arms upwardly and means for limiting the upward movement of the same, substantially as set forth.

In testimony whereofl afiix my signature in presence of two witnesses.

POLAD ORE M. REED.
