To all whon'z/ it 711/14 concern/.-

Be it known that l, \VILLIs C. BURDON, a citizen of the United States, resident of Louisville, in the county of Jell'eison and 5 State of Kentucky, have made a certain new and useful lnv; tion in Trolley-Controllers; other convenient manner. '..hepawl-slide is and I declare the following to be a full, ele 1', designed to move freely up and down on the and exact description of the same, such as catch-bar in zueordance with the movements will enable others skilled in the art to which of the trolley-pole and is of sullicient weight [0 it appertains to make and use the invention, to take up the slack of the rope at all times.

This cam-lever Zhas a camhead which is normally in close proximity to the inner surface of the bar d, and upon a sudden surge or jerk of the trolley-rope the connection-spring will yield and the camhead of the lever Z be caused to engage with the inner surface of the bar (1 in a frictional manner, so that the trolley-pole will be locked down until adjusted to proper position by the conductor.

An antifriction-roller 0 is employed at the upper end of the member p, working against the bar d.

Having described the invention, what I claim, and desire to secure by Letters Patent,

1. In a trolley-controller, the combination of a vertical catch-bar attached to the wall of the car, a slide working upon said bar and consisting of a main portion and a secondary portion pivoted to said main portion, a pulley carried by said secondary portion and adapted to engage a loop of the trolley-rope, a tension-spring connecting said main and secondary portions, and means for engaging said vertical catch-bar to stop the movement of the trolley-pole and slide upon sud den upward movement of the same.

2. In a trolley-controller, the combination ofavertical bar attached to the wall of the car, a slide working upon said bar and consisting of a main portion and a secondary portion pivoted to said main portion, a pulley carried by said secondary portion and adapted to engage a loop of the trolley-rope, a tensionspring connecting said main and secondary portions, a cam-lever device pivoted to said main portion, and means in connection therewith for causing said lever device to engage the vertical bar to stop the movement of trolley-pole and slide upon sudden upward movement of the same.

3. In a trolley-controller, a vertical bar attached to the wall of the car, a slide working upon said bar and consisting of a main portion and a pivoted portion carrying a pulley enga ing a loop of the trolley-rope, a tensionspring connecting said main and pivoted portions, a lever pivoted to said main portion and having a tail resting upon a lug of the pivoted portion, said lever having a camhead adapted to frictionally engage the vertical bar to stop the movement of the trolleypole and slide upon upward movement of the same, substantially as specified.

4. In a trolley-controller, a vertical bar attached to the wall of the car, a slide working upon said bar and consisting of a main portion and a pivoted portion carrying a pulley engaging a loop of the trolley-rope, a lever pivoted to said main portion and having an arm resting upon the pivoted portion, said lever having a cam-head adapted to frictionally engage the vertical bar to stop the movement of the trolleypole and slide upon upward movement of the same, substantially as specified.

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

WILLIS C. BURDON.
