LEVI G. MOWRY, OF BUFFALO, NEW YORK.

TROLLEY-CATCHER.

SPECIFICATION forming part of Letters Patent No. 517,166, dated March 27, 1894.

Application filed December 11,1893. Serial No. 493,308- (No model.)

To all whom it may concern.-

Be it known that I, LEVI G. MOWRY, a citizen of the United States, residing at the city of Buifalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Trolley-Catchers, of which the following is 'a specification.

Tl11s invention relates to a device for automatically depressing the trolley out of reach of the transverse arms or cross wires which support the trolley-wire, in case the trolley accidentally leaves the wire. The trolley usually runs against the under side of this wire and 1s pressed against it, by springs applied to the trolley pole. When the trolley aceldentally leaves the wire, these springs swlng the pole and the trolley above the wire, causing the pole to strike the supporting arms and cross wires in its path. The pole is thus not only liable to become bent or broken as well as to injure or break such cross wires or arms, but the trolley, by catching in one of the forks at the junction of the switch wires w1th the main wire, is liable to tear the trolley pole from the top of the car.

The object of my invention is the provision of a reliable device which shall depress the trolley below the system of supporting arms or cross wires in the event of the trolley leavmg the wire and which will hold the same in that posltion until it is released and replaced agalnst the Wire by the conductor or other attendant.

In the accompanying drawings consisting of two sheetsz-Fignre 1 is a side elevation of a street car provided with myimproved depress- 1ng device. Fig. 2 is a sectional elevation of the device, on an enlarged scale, showing the depressor rod in its normal, elevated position. Fig.3 is a front view of the device. Fig. 4 is a horizontal section in line 44, Fig. 2, look- 1ng upward, showing the position of the parts when the depressor rod is locked in its elevated position. Fig. 5 is a similar section taken on the same line, showing the position of the parts when the depressor rod is released.

Like letters of reference refer to like parts in the several figures.

A represents the trolley wire, B the trolley pole attached to the top of the car in any ordinary manner, I) the trolley journaled at the upper end of the pole, b the spring connected with the pole for pressing the trolley against the wire, and c the rope attached to the upper portion of the pole for lowering it by hand.

D is a vertically movable depressor connected with the trolley pole, for lowering the same when the trolley accidentally leaves the wire. This depressor consists of a vertically swinging rod or bar pivoted at its lower end to a base board E, which is preferably removably attached to the dash board of the car. For this purpose the board is provided at its upper end with hooks e which engage over the upper edge of the dash board and the latter is provided on its front side, near its lower end, with removable pins or bolts (2', which are arranged in perforated horizontal ears 6 secured to the dash board and which overlap the projecting ends of a cross bar 6 secured to the lower end of the base board, as clearly shown in Figs. 2 and 3. The depressor rod is provided atits lower end with a cylindrical cross head or bar (1, the end portions of which are journaled in bearings d secured to the board E. The lower end of the trolley rope may be attached directly to the upper end of this depressor rod, but it is preferably secured to the upper end of an adjustable rod 01 which telescopes into the hollow depressor rod and is secured therein by a set screw 01 F is a spring applied to the depressor rod and tending to swing the same downwardly and outwardly. This spring preferably consists of a loop bearing with its outer bow-portion against the rear side of the depressor rod, and coils ff surrounding the cylindrical cross head of said rod on opposite sides of the latter and bearing with their'end portions f against the board E.

G is a bracket or horizontal supporting plate secured to the upper portion of the base board E and having a longitudinal slotgadapted to receive the depressor rod.

H is a holder whereby the depressor rod is confined in the slot of said bracket and held in its upright position against the pressure of its spring. This holder is approximately U- shaped and is pivoted to the under side of the bracket, on one side of, the slotot' the latter, by a vertical'pin h passing through alug formed on the curved portion of the holder,

so that the latter is capable of swinging horizontally. The front arm or member 71. of this holder is adapted to extend across the slot of the bracket G, in front of the depressorrod as shown in Figs. 3 and 4, and the holder is locked in this position by acatch I. The latter consists of a horizontal elbowlever pivoted to the under side of the slotted bracket G on the side of the slot opposite that on which the holderis pivoted. The long rear arm t'of this catch is arranged adjacent to the base board E, while its short front arm t" extends forwardly from the pivot of the catch and is provided with a locking nose or shoulder 71 with which the front arm of the holder is adapted to interlock, as shown in Fig. 4, thereby holding said arm against outward movement and confining the depressor rod in its upright position.

j is a spring whereby the locking shoulder of the spring catch is held in engagement with the holder and which consists preferably of a coil surrounding a depending stud 7" secured to the bracket G and bearing with its front branch against the rear side of the shouldered arm of the catch and with its other branch against the base board.

K is a trigger or trip lever whereby the spring catch I is unlocked from the holder, for releasing the depressor rod. This trigger is arranged above the slotted bracket G and mounted on a horizontal pivot carried by the base board. The actuating arm kof this trigger extends forwardly from the pivot of the latter, while its rear arm 71: extends downward from said pivot and engages against the rear side of the releasing arm t'of the locking catch.

Z is a trip or branch cord attached at its upper end to the main trolley rope c and at its lower end to the actuating arm of the trigger K, as shown in Fig. 1. This trip cord is of such a length that when the trolley isin engagement with the wire, the cord hangs slack and does not affect the trigger, while when the trolley leaves the wire and rises above the same, the cord is drawn taut and caused to pull the trigger.

When the parts are in the normal position, shown in Figs. 1, 2, 3 and 4, and the trolley accidentally runs oif the wire, the trip cord pulls the trigger, causing the depending arm of the latter to move forwardly and swing the rear arm of the locking catch in the same direction. This movement causes the front arm of the catch to move laterally out of engagement with the front arm of the holder, and the latter being new unlocked, releases the depressor rod and permits the same to be swung down by the reaction of its spring. As the rope of the trolley pole is connected with the depressor rod, the pole, with the trolley, is drawn down by the rod clear of the supporting arms or cross wires of the system and held in that position until the depressor rod i is again elevated. Injury to such wires and arms and to the trolley pole is thus obviated, and the danger to life incident to the use of trolley poles unequipped with such an automatic depressor is avoided.

The depresser rod in swinging down moves aside the front arm of the released holder, whereby the latter is swung into the position shown in Fig. 5, the outward movement of the holder beyond this position being limited by a stop m arranged on the under side of the slotted bracket G. When the holder is moved into this position, the outer end of its rear arm 71.2 interlocks with the shoulder 11 of the spring catch as shown in Fig. 5 and thus reliably retains the holder in the proper position for permitting the depressor rod to enter the slot of the bracket when it is elevated.

Upon elevating the depressor rod to its normal upright position, it strikes the rear arm of the holder and swings the same rearwardly, causing its front arm to swing across the slot of the bracket in front of the depressor rod and deflect the locking arm of the spring catch until it interlocks with the shoulder thereof as shown in Fig. 4. The depressor rod is thus locked automatically by the act of swinging it into its normal position.

It will be observed that the rear arm of the holder performs the double function of looking the holder in its open position when the depressor rod is released and swinging the holder into its closed position when said rod is elevated, and that the spring catch serves the double purpose of locking the holder in its open position as well as in its closed position.

By providing an adjustable connection between the trip cord and the depressor rod, as shown,the length of this cord can be properly and conveniently regulated, without disturbing its connection with the main trolley rope.

\Vhen the car reaches either terminal of the line, the depressing device is readily transferred to the opposite end of the car, by removing the bolts 6 of the dash board and disengaging the hooks of the base board from the dash board. In order to permit the device to be applied to either end of the car, each dash board is provided with a set of perforated ears e I claim as my invention- 1. In a trolley catcher, the combination with a swinging depressor rod, of a holder for retaining the depressor-rod in its normal position, and a trip or releasing device operating on said holder and connected with the trolley, substantially as set forth.

2. In a device for lowering trolleys, the combination with a pivoted depressor rod,.and a spring for lowering the same, of a locking device for retaining said depressor rod in its normal position, and a trip deviceacting upon said lock and connected with the trolley, sub- }stantially as set forth.

3. The combination with apivoted depressor rod and a spring for lowering the same, of a jholder for retaining the depressor rod in its elevated position, a catch for locking said holder, and a trip device for releasing said locking catch connected with the trolley, substantially as set forth.

7. The combination with a support and a bracket attached thereto, of a depressor rod pivoted to said support and having a spring for lowering it, a swinging holder pivoted to said bracket and having a front arm and a rear arm, a spring catch also pivoted to said bracket and having a releasing arm and a shouldered locking arm engaging with the front arm of the holder, a trigger having an arm engaging against the releasing arm of the spring catch, and a cord connecting the actuating arm of the trigger with the trolley, substantially as set forth.

8. The combination with. the pivoted depressor rod and its locking and releasing devices, of a trip cord, connected with the trolley, and an adjustable attachment connecting said trip cord with the depressor rod, substantially as set forth.

9. The combination with the pivoted hollow depressor rod and its locking and releasing devices, of a telescopic rod adjustably secured in the hollow depressor rod, and a trip cord attached to said telescopic rod, substantially as set forth.

10. The combination with the detachable base board carrying the parts of the trolley depressor, and provided at its upper end with hooks adapted to engage with the dashboard of the car and at its lower end with a cross bar, of the dash board having removable bolts or pins which overlap the end portions of said cross bar, substantially as set forth.
