SIDNEY II. SHORT, OF CLEVELAND, OIIIO.

TROLLEY-STAN D.

SPECIFICATION forming part of Letters Patent No. 584,606, dated June 15, 1897.

Application filed February 16, 1897- Serial No. 623,757. (No model.)

T at whom, it may concern.-

Be it known that I, SIDNEY H. SHORT, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Trolley-Stands; 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.

My invention relates to a trolley-stand, the object being to provide simple, cheap, and effective construction whereby the trolleyarm when in service will have no lateral motion, but which may nevertheless be drawn out of contact with the conductor and then turned around so as to reverse its position relative to the car, whereby it will be operative when the car runs in the reverse direction.

The invention consists of a base adapted to be secured upon a motor-car, a trolley-arm support pivoted to said base upon a horizontal pivot, said trolley-arm having a rigid finger extended below its pivot, which, when the trolley-arm is in operative position, engages with a slot in the base, thereby preventing lateral movement of the trolley-arm, but which is disengaged when the trolley-arm is drawn down, whereby the trolley-ar m support may be turned on its pivot one hundred and eighty degrees to reverse the position of the trolley-arm.

It also consists in the more specific combination of parts hereinafter described, and pointed out definitely in the claim.

In the drawings, Figure 1 is a side elevation of what is perhaps the best embodiment of the invention. Fig. 2 is a plan view thereof. Fig. 3 is a side elevation; and Fig. 4 is a side elevation, partly in section, of an alternative construction. Fig. 5 is a rear elevation of same.

Referring to the parts by letter, A represents the base, which is adapted to be secured to the top of the car, B a trolley-arm sup port, which is pivoted on a vertical axis to the base, and O a trolley-arm, which is pivoted on a horizontal axis to the support B. A finger c is rigid with the trolley-arm and extends below its pivot and engages in a slot or slots in the-base into which said finger .11 b represent two parallel vertical ears between which the lower end of the trolley-arm projects and to which it is pivoted by the pin 0 Two fork-arms c c are rigidly connected with the trolley-arm outside of the ears b and two contractile coil-springs D D, which are connected at their ends with these fork arms 0 and with two arms 19 b, which are rigid with the support 13, exert their force to move the outer end of the trolley-arm upward and into contact with the conductor.

When the trolley-arm is in service, it stands,

preferably, at an angle of about forty-five degrees to the car, and when in this position the finger c enters the slot formed between the two cars a ct on the base. WVhen the trolley-arm is drawn down, the finger is withdrawn from said slot at and the support may be turned upon its vertical axis. IVhen it has been turned one hundred and eighty degrees, the

trolley-arm may be allowed to rise and the finger a will enter another slot ctZdiametrically opposite to slot a and between two other cars a a IVhen the finger is in either slotand it is in one or the other when the trolley is in service the support cannot turn.

In the embodiment of the invention shown in Figs. 3, 4:, and 5 the base is provided with a cylindrical stud 0. which passes through the bottom of the support and projects between the two ears 19 19 In the top oi? this stud is a slot a The finger c on the trolleyarm enters this slot when the trolley is in. service, is withdrawn therefrom when the trol- Icy-arm is drawn down, and again enters the small slot when the support has been turned one hundred and eighty degrees on its vertical axis.

In the construction shown in Figs. 3, 4c, and 5, inclusive, the trolley-arm, which lies between the ears h is secured by a set-screw c to a shaft c, which is free to turn in said cars 6 The fork ends 0 are secured by a set-screw 0 to the ends of this shaft. I

The particular construction described in the last paragraph may be varied at will without departing from the invention.

Having described my invention, I claim The combination of a base having a slot, a trolley-arm support pivoted to the base on a Vertical axis, a trolley-arm pivoted to the support on a horizontal axis, and a finger rigid with said arm and extended below its axis and adapted to enter said slot When the trolley-arm is in service, but to be Withdrawn therefrom when said arm is drawn down, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two Witnesses.

SIDNEY H. SHORT.
