4Be it. known 4that I, FRANK Alliance, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Trolley-Contacts, of which thefollowing isa specification.

An object of my invention is to provide a new and improved contacting device for use with trolley systems of electric railways for operating signals, or other translating devices, by means `of a current passed through the contact from the trolley-wire. A further object of the present invention is to provide simple and efficient means particularly adapted for cars running at a high rate of speed and of such a character that the contact with the trolley-wheel will produce the slightest shock possible, thereby eliminating serious troubles heretofore encountered.

In the accompanying drawing, which illustrates an applicationI of my invention, Figure l is a side elevational view of a trolley contacting device constructedin accordance' with my invention, shown in connection with a trolley-wire; Fig. 2, a diagrammatic plan; Fig. 3, a part end view and a part sectional view, the section being taken on line III-III of Fig. 1; Fig. 4, a vertical sectional view taken on line IV-IV of Fig. 1; Fig. 5, a sectional View taken on line V-V of Fig. 1; and Fig. 6, a sectional view taken on line VI-VI of Fig.. 1.

Referring to the drawing, 1 designates a trolley-wire secured.l to and supported by ears 2 in, the usual nimmer. Extending longitudinallyof the trolley-wire and supportedby the same suspension means as sup-.

' The vertically extending portion of the respective rods is projectedy up` through the support 4. and secured thereto by nuts, as particularly shown by Fig. `3, These metallic rods,'or the longitudinally ,extending portions 6 thereofl are located in a lower horizontal lane than the trolley-wire 1, and are adapted)to supportapair of flexible cone Atact strips 7 disposed on both sides of the T. COPE, of

trolley-wire. The opposite ends of the rods 5 6 are supportedlby a metallic bracket 8 secured to and depending from the support 4, as particularly shown by Fig. 6. One of vthe bolts as 8, may be employed as a conneet-ion between the bracket and awire (not shown) leading to a signaling device.

As illustrated and as preferred, the flexi- 'ble contact strips 7 are made of some suitable thin sheet metal and areeach provided on its lower edge with a series of engaging members 9,'said members 9 being adapted to be bent around the respective iongitudinally extending rods, as particularly shown by the sectional views Figs. 4 and 5. Strips 7 are loosely mounted on thev respective rods with the lower edges in a horizontal plane f considerably below the plane of the trolleywire on said rods. As illustrated,these thin yielding contact strips are inclined toward each other and have their upper inner edges resting upon metallic spreaders or stops 10.

Looatedat intervals along the strips 7, I provide springs 11, the latter being designed to vcontrol the movement of the strips. Springs 11 are preferably supported on light supporting members 12 secured to and proi jecting upwardly from the contact strips or members 7. Y

adapted to enter between the contact strips and makepositive frictional contact therewith spreading the movable and iiexible strips during the passage of the wheel through the contact device in a manner par- J f v 13 designates the trolley-wheelwhich' is ticularly shown in the diagrammatic View'.

What I claim is:

1. The combination of a contacting device including a metallic rod having a longitudinally extending portion disposed in a plane lower than the trolley-wire, and a bodily movable and yflexible contacting strip loosely connected at its lower edge,with the rod in a horizontal plane below` the trolley wire.

. 2. The combination with a trolley-wire, of a contacting device including a longitudinally extending insulating support, apair vof metallic rodseach having a longitudinally extending portion disposed `in a plane lower than the trolley-wire, a pair of bodily movable and. flexible contact strips cach respectively loosely connected at its lower edge with a rod in a horizontal plane below the trolley-wire.

3. The combination with a trolley-wire` with a trolley-wire, i

of a'contacting device including a longitudinally extending insulating support, a pair of metallic rods each having a longitudinally extending portion Vdisposed in a loiver than the trolley-Wire, and a 'p' oflongitudinally extending metallic rods, a n pair of bodily movable contact strips each spring-controlled bodily movable. and lexi ot er, and a member located betweenthe l30 v ble contact strips each loosely connected upper free ends of the strips.

with one of the rods in a horizontal plane e combination With a trolleywire, below the trolley-`vvireof a contacting device including a pair of 4. The combination with a trolley-Wire, longitudinally extending metallic rods, a of a contacting device including a longitupair of bodily movable cont-act strips each 35 dinally extending insulating support, afinerespectively loosely connected With one of tallic rod secured at one end to the insulatthe rods, said strips having their upper ends ing support and having a longitudinally eX- free and inclined toward each other, a me tending portion disposed in a plane lower tallic member interposed between the upper than the trolley-Wire, a. bracket at the oppofree ends of the contact strips, and a spring 40 connecting said strips.
