TROLLEY-POLE.
Specification of Letters Patent.
Patented June 24, 1913.
Application filed October 9, 1911. Serial No. 653,632.
To all whom, it may concern:
Be it known that I, AUcUs'rn Lnvns UE, a citizen of the United States, residing at New Bedford, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Trolley-Poles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to trolley pole attachments and has for its object to provide a device of this nature wherein constant pressure will be exerted in a vertical plane directly upon the wire.
Heretofore in the construction of trolley poles a pressure has been exerted upon the wire from springs located at the base of the pole, there being no independent pressure adjacent to the wheel or roll. The distance between the trolley wheel or roll and the base of the pole where the pressure is exerted greatly decreases the force of the pressure and increases the liability of the wheel or roll to jump the wire.
It is the object of the present invention to overcome this objectionable feature by providing independent pressure for the wheel or roll at the upper terminal of the trolley pole, which pressure in combination with the pressure now in use, will greatly increase the practical merit of trolley poles and insure the non-jumping of the wheel.
lVith the above and other objects in view, this invent-ion consists in the construction, combination and arrangement of parts, all as hereinafter more particularly described, claimed and illustrated in the accompanying drawings, wherein:
Figure 1 is an elevationof the outer terminal of a trolley pole, embodying the present invention, illustrating the same cooperating with the wire; Fig. 2 is a plan top view thereof; and Fig. 3 is a vertical section taken along line 3-8 of Fig. 1.
Referring more particularly to the drawings 10 indicates a trolley pole attached to a car in any suitable manner, having its upper terminal flattened as at 11 to rest in a horizontal plane, said flattened portion 11 being provided with a central, internally threaded opening 12. A cup or cylinder 13 is threaded into the opening 12 at its upper terminal, and is provided with an orificed closure 14: which is threaded into the interior of the cup. A piston rod 15 reciprocates through the opening of the closure'lat and carries a detachable piston 16 at its lower terminal. A spring 17 is interposed between the piston 16 and the bottom of the cup or cylinder 13 and normally tends to force the piston rod upwardly. At the upper terminal of the piston rod is formed a yoke 18 between the arms of which is rotatably mounted a trolley wheel 19 through the instrumentality of the shaft 20. Thus it will be seen that the action of the spring 17 forces the trolley wheel 19 into engagement with the trolley wire 21, thereby insuring the positive engagement therewith and the additional pressure exerted by said spring also eliminates the liability of said wheel jumping the wire 21. I
A brace 22 is interposed between the base of the cylinder 13 and the oblique portion of the main body portion of the trolley pole 10, and is adapted to normally rest at right angles to said trolley pole. A bolt 23 pierces the trolley pole and secures the adjacent terminals of the brace 22 thereof through the instrumentality of the nut 24. A. spring 25 is secured to the bolt 23 and carries at its free terminal a yoke 26, said yoke being pivotally connected to the projecting terminals of the shaft 20.
From this construction it will be obvious that the trolley wheel 19 is retained in positive engagement with the wire 21, and that the mechanism at the top of the pole is thoroughly braced and will in no way become loose by the jars to which the pole is subjected.
Having thus fully described my invention, what I claim as new and desire to secure by U. S. Letters Patent, is-
In a trolley, the combination with a trolley pole, a cylinder, means for connecting said cylinder to the trolley pole, a piston reciprocating in the cylinder, a spring interposed between the piston and the cylin- In testimony whereof I affix my signature der, a harp supported by said piston, a trol- 1n presence of two wltnesses.
ley Wheel mounted in the harp a U-shaped yoke pivotally connected to the harp, a bolt AUGUSTE.
passing Through the trolley pole and having \Vitnesses: an eye formed on one end thereof, and a 0011 THEODORE LEvns UE,
spring connecting said yoke to the bolt. EMILE AUGER.
