TROLLEY-POLE FOR CONDUCTING ELECTRIC CURRENT T VEHICLES.
Specification of Letters Patent.
Patented June 11, 1907.
Application filed June 26,1905. Serial No. 267,159.
To aZZ whom it may concern.-
Be it known that we, JOHN LINDSAY and ROBERT LINDSAY, subjects of His Majesty the King of Great Britain and Ireland, residing at Dunedin, in the Provincial District of Otago, in the Colony of New Zealand, carpenter and engine-driver, respectively, have invented certain new and useful Improvements in Trolley-Poles for Conducting Electric Current to Vehicles, of which the following is a specification.
This invention relates to trolley poles used upon vehicles for conducting electric current from an overhead wire to the motor upon the car and consists in improvements whereby the trolley pole may be easily reversed when the direction of the car is changed.
According to this invention the trolley pole is pivoted at its base to a bracket in any ordinary manner and provided with springs and connecting parts which tend to keep the trolley pole in a vertical position. The pole is divided into two parts, the bottom part or inner tube telescoping into the upper part or outer casing. A spring is introduced between two collars one secured to each of the said outer casing and inner tube. The outer casing or upper part of the pole is thus free to slide upon the inner tube. when the spring is compressed. At the upper end of the trolley pole are provided two eyes one on each side of the pole. A rope has one of its ends attached to one of the eyes and passes down to a pulley sheave fixed upon the front of the car then upon rollers along the roof to a pulley sheave at the other end of the car, and is then returned and has its other end attached to the other eye of the trolley pole. The rope is thus always ready for the conductor to operate the trolley pole without getting off the car. When the trolley pole is reversed the outer casing telescopes upon the inner tube, the spring compressing to allow of this movement.
The drawing illustrates the invention Figure 1 is a side elevation of a car fitted with our invention. Fig. 2 is a side sectional elevation. Fig. 3 a front elevation of the trolley pole and its bracket. Fig. 4 is a section on line AA, Fig. 3, and Fig. 5 is a sectional elevation through the trolley wheel and its jaw.
The trolley pole is divided into two parts, the bottom part or inner tube 1 telescoping into the upper part or outer casing 2. A collar 3 is secured upon the inner tube 1 by rivets 4 and another collar 5 is secured upon the inside of the outer casing 2 by rivets 6. The upper end of the inner tube 1 is reduced in diameter to pass through the collar 5 and provide an annular space 7 for a spring 8 which is introduced between the collars 3 and 5. A socket 9 is screwed upon the bottom end of the outer casing 2 for which it forms a guide by sliding upon the inner tube 1. A cap 10 is screwed to the top of the outer casing and carries the head piece 11 which has the usual jaw 12 and trolley wheel 13. The inner tube 1 is pivoted upon a pin 14 in a bracket 15 attached to the car.
The pole is kept upright in any ordinary manner but preferably by springs 16 and 17 which are mounted upon bolts 18 and 19 pivoted to the pole in jaws 20 and 21 by pins 22 and 23. The springs are in compression between washers 24 and 25 and the ends of the bracket 15 and the tension of the springs is adjusted by means of nuts 26 and 27'. A bar 28 adapted to work in a slot 29 provided in the outer casing 2 passes through the top of the inner tube 1 and is secured thereto by a bolt 30. Holes 31 and 32 are provided in the ends of the bar 28 and a rope 33 has one end fixed in the hole 31, passes down to a pulley 3 L fixed upon the front of the car and is carried over the roof of the car upon rollers or pulleys 35, around a pulley 36 at the rear end of the car and thence upward to the hole 32.
The head piece 11 is made solid and is provided with contact pieces 37 and 38 inside the jaw 12 in which the trolley wheel 13 revolves. The contact pieces are secured to the jaw by rivets 39 and 40 and have holes through which the pin 11 of the trolley Wheel passes.
To reverse the pole the conductor goes to the front of the car and pulls the rope which causes the trolley wheel to run along the trolley wire, the weight of the trolley Wire and outer casing compressing the spring so that the trolley wheel does not leave the wire.
What I do claim and desire to secure by Letters Patent of the United States is In apparatus for the purpose indicated in combination, a trolley pole pivoted in a bracket upon the top of a car, and having an outer casing telescoping upon an inner tube, a spring supporting the outer casing upon the inner tube, a bar secured to the top of the inner tube and having holes, a rope attached at one end to one end of the bar, a pulley sheave upon the front of the car around which the rope passes, pulleys upon the top of the car names to this specification in the presence of over which the rope passes, a pulley sheave two Witnesses. upon the rear of the car around Which the ROBERT LINDSAY. rope passes, the rope having its other end at- I JOHN LINDSAY. 5 tached to the other end of the bar, substan- Witnesses: l tially as specified.
