UNITED STATES PATENT EEICE,
ALBERT B. CROUNSE AND CHARLES A. RUTLEDGE, OF PASSAIC, NEW JERSEY.
TROLLEY-WIRE HANGER.
SPECIFICATION forming part or Letters Patent No. 519,446, dated May 8, 1894. Application led July 21,1893. Serial No. 481,158. (No model.)
To all whom t may concern: Y
Beitknown thatwe, ALBEETB. CRoUNsE and CHARLES A. RUTLEDGE, citizens of the United States, residing at Passaic, in the county of Passaic and State of New Jersey, have made a new and useful Improvement in Trolley- Wire Hangers or Supports, o f which the following is a specification.
Our invention is directed particularly to improvements in insulated hangers or supports for trolley wires used in connection with electric railways where such trolley wires are sustained on cross arms or cross trees from overhead and its objects are, first, to afford better insulation to this type of hangers, and second, to provide ahanger which will be possessed of great strength and durability. These objects are accomplished by the novel form of hanger or support hereinafter described and particularly claimed at the end of this specification.
For a full and clear understanding of our improvement reference is had to the following specification and accompanying drawings, in which- Figure l represents a side elevational view of the hanger, and Fig. 2 a vertical sectional View thereof through the body, parts being shown in elevation. Fig. 3 is a plan view of awasher which rests upon the insulatingliquid in the body of the insulator cup.
Referring now to the drawings in detail in all of which like letters of reference represent like parts whereverused, A represents a rod preferably of metal which is supported on the cross arm or cross tree through the agency of means passing through holes a a in its opposite ends.
B represent-sa sheathing of insulating ma pletely and thoroughly in'sulates the upper portion of the standard S and the two metallic clasps or bands C C.
The trolley wire proper, not shown, is supported from the lower endof the standard S by the usual well known form of clip or Asupport.
The insulating sleeve T is provided with a screw thread t near its central portion and adapted to 'receive a petticoated insulator R made of glass in the well known manner, and provided with an inner receptacle adapted to receive oil or other insulating liquid O. The space between this petticoated insulating cup R and the lower end of the insulating sleeve T is shown as partially filled with insulating material F, such as sealing wax, asphalt or the like. This space may be entirely filled with such insulating material if preferred after the insulator R has been secured in place.
W is an insulating washer made of leather, vegetable fiber or the like and adapted to direct any moisture which might accumulate on the upper portion of the sleeve T into the receptacle which contains the oil O.
H is a protecting shield or cap which covers the insulating cup R and is rendered adjustable vertically upon the sleeve T by screws s, the arrangement being such that it may be raised into the position shown in dotted lines when it is desired to remove or replenish the oil O in the cup R.
D is a washer made of a strip of wood w and corresponding strips of leather l and 'o' and adapted to iioat upon the surface of the oil and prevent it from being thrown out by undue vibrations as the trolley passes beneath the support.
The operation of the entire apparatus it is believed will be fully understood in view of the foregoing description.
We do not limit ourselves to the special construction herein shown and described as we believe it is broadly new with us to provide a trolley hanger or support with'A an insulating medium in the nature o f oil which shall prevent the creeping of moisture. Nor
do we limit ourselves to` the special location of such insulating medium, and our claims are generic in this particular.
Having thus described our invention,what We claim, and desire to secure by Letters Patent of the United States, is-
l. A trolley hanger or support provided at its upper end with means for insulating it from the sustaining arm, in combination with an insulating cup containing oil or a liquid insulating medium, substantially as described.
2. A trolley hanger or support insulated at its upper end from the sustaining arm and surrounded by an insulating sleeve, in combination with a petticoated insulator secured to the insulating sleeve by a screw thread, substantially as described.
3. A trolley hanger or support insulated at its upper end from the sustaining arm and throughout its body by an insulating sleeve which sleeve in turn sustains an insulating cup, substantially as described.
4. A trolley hanger or support insulated from its sustaining arm, in combination with an insulating cup containing an insulating liquid which surrounds the hanger or support, said cup being provided With means for preventing the liquid from escaping, substantially as described. 4
5. A trolley hanger or support insulated from its sustaining arm and surrounded by an insulating cup containing an insulating liquid, in combination with adjustable means 3o for preventing theliquid from escaping, substantially as described.
6. A trolley hanger or support provided with an insulating cup containing a liquid insulating medium and a floating Washer which 3 5 retains the liquid in place, substantially as described.
7. A trolley hanger or support provided With an insulating cup containing a liquid in sulating medium, in combination with an ad- 4o a surrounding insulating cup containing an 45 insulating liquid, in combination with a movable cap for the cup adj ustably secured above its top, substantially as described.
In testimony whereof we have hereunto subscribed our naines this 15th day of July, 1893. 5o
