T (1Z5 whom it may concern.

Be it known that 1, Louis Zsr novsznr, a subject of Austria-Hungary, residing at Philadelphia, in the cour of Philadelphia and State of Perms \ania, have invented new and useful Improvements in Telephone Mocha: m for lrolley-Cars, of which the following is a specification.

My invention relates to new and useful improvements in telephone mechanisms for trolley cars, and has for its object to pro ride an exceedingly simple and effective dcvice of this character whereby a person riding upon the trolley car may either send or receive a n'iessage. thus permi ting conversat-ions to be car-ied on when a person is traveling or orders may be transmitted to the crew of the trolley car from the oes patchers ollice, or the position of the different cars along the line may be transmitted to the crews of different cars thus enabling the cars to be operated without the likelihood of wrecks, or accidents.

A further object of the invention is to provide a metallic circuit in the form of two wires parallel with each other and with the feed wire, but in a slightly lower plane than said feed wire, and with which con t-acts a pair of wheels each carried upon a separate arm, said arms being pivoted to a split collar mounted upon and insulated from a pipe or tubular pole carried by the car, each of said arms being held in a non mally raised position, whereby the wheels are held in contact with the circuit wires independent of the means which hold the pole in a normally raised position so that any irregularities the positions of the circuit wires may be compensated for.

ll ith these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawings forming a part of this specification, in which Figure l is a side elevation of one end of a trolley car partly broken away to illustrate the construction and showing my improvement applied thereto. Fig. 2, is an end view thereof. Fig. 3, is a side elevation of the pipe or tubular pole carrying the contact wheels, the casing hereon being shown in section. a, similar view at right angles to Fig. "1 is an enlarged end view thereof, and a portion of the arms being broken away; and (S, a section at the line P4 of 5.

in c rr fling out my invention as here embodied represents a trolley car provided with the ordinary trolley pole and trolley at which contacts with the feed wire 5.

On the car at some suitable point is placed the box or booth 6, said booth being;- preferably mounted on the on. .Idc of one. of the end walls and in which is placed the telephone set having wires 8 and 9 leading therefrom, said wires passing through the car in any suitable manner, either between the diii'erent parts of the wall or through a suitable molding through the roof thereof and into the tubular pole or pipe 10.

The tubular pole 10 is mounted upon the roof of the car in any suitable manner, pref-- erably similar to the ordinary trolley pole, the construction of which is well known in the artand to mechanics engaged in this class of work.

The wires 8 and 9 pass through the tubular pole 10 and out of the upper end thereof which is open and are secured to the arms 11 and 12, the lower ends of which lie at right angles as at 13 and these enos are each provided with a disk 1% mounted in the oppositely disposed sockets 15 of the split collar 16, the sections of said split collar being held together in any suitable manner such as by bolts 1' The split collar is secured to the tubular pole adjacent its upper end and is insulated therefrom by suitable insulating" material 18 interposed between the sections of the split collar and the tubular pole.

On the outer ends of the arms 11 and iii are journaled the contact wheels is and 20 which engage the wires 21 and 22 of the metallic circuit, said wires running parallel with each other and each parallel feed wire. but in a position some distanc' below said feed wire, so that when ti trolley leaves the feed wire it is not likely to hit either of the wires of the metallic circuit which mightcause said wires to be torn from their fast nings, and as said wires are mounted some distance on either side of the feed wire, it will be impossible for the trolley pole to contact with either of sait circuit wires and the feed wire at the same time.

In order that the contact wheels may be held in engagement with the circuit wires regardless of any irregularities between said wires I provide means for holding said wheels in a normally raised position here shown as comprising helical springs 23 and 24, each secured to one of the arms 11 and 12, and to one of the walls of the box or casing 25, said box or casing being mounted upon the tubular pole 10 by means of a sleeve 26, and the walls of said casing extend above the upper end of the tubular pole 10 and above the point whereby the ' wires 8 and 9 and the springs 23 and 24 are attached to the arms 11 and 12, thus protecting said a parts from displacement or breakage, should the contact wheels 19 and 20 accidentally leave the circuit wires.

From the above description it will be understood that an electrical circuit is obtained through the wires 21 and 22 of the metallic circuit through the contact wheels 19 and 20, the arms 11 and 12 on which said contact wheels are journaled, the wires 8 and 9 secured to said arms and running through the tubular pole l0 and the car and the telephone set 7 Of course I do not wish to be limited to the exact details of construction as here Copies of this patent'may be obtained for five cents each,

the wires are connected shown as these may be varied within the limits of the appended claim without departing from the spirit of my invention.

'Having thus fully described my invention, what I claim as new and useful, is- In a device of the character stated a tubular pole, a split collar provided with sockets mounted on said pole adjacent its outer end, an insulating material interposed between the sections of said split collar and the pole a pair of arms each provided with a disk for pivoting said arms in the sockets of the split collar, outer ends of said arms, wires leading from said arms and passing through the tubular pole, a casing carried by the outer end of the tubular pole surrounding the arms and projecting upwardly above the point where contact wheels journaled in the with said arms, and

springs each secured to one of the arms and 1 to one of the walls of the casing within the same, whereby either of said arms is held in a normal raised position independent 01": the other.

In testimony whereof, I have hereunto affixed my signature in the presence of two subscribing witnesses.
