DEVICE FOR TROLLEY-CONDUCTORS.
Specification of Letters Patent. Patented Apr. 12, 1921.
Application filed March 9, 1918. Serial No. 221.389.
device of the above-indicated character that shall be simple and durable in construction and economical to manufacture.
Another object of my invention is to provide an approach for trolley-conductor devices that shall comprise a relatively small number of parts, be readily transportable as a unitary structure and be readily mounted in operative position on a trolley conductor by the use of a simple tool, such as a hammer.
Inpractising my invention, I provide a removable extension member for av frog or other trolley-conductor device to take up the shocks and wear thereto incident to the passage of trolley contact members and which is so related to the frog and conductor, by the engagement of relatively broad surfaces, as to provide a rigid and efliclent mounting for the same. I
Figure 1 is a top plan view 0f a por t1on of a trolley frog embodying my mventlon; Fig. 2 is an end view of the device, as shown in Fig. 1; and Fig. 3 is a side view, partially in section, of the device shown in Flgs. 1 and 2.
A frog 1, for attachment to trolley conductors 2, the. approaches to only one end of which are shown, comprises channel portions 3 of substantially U-section, in which the converging conductors 2 are disposed and to which the latter may be attached in any suitable manner. An extension member4 preferably of malleable material, pro ecting from each of the approaches to the frog 1, but only one of which is shown, has a channel portion 5 for embracing the conductor 3, a flat end face 6 that engages the end of the approach to the frog, and a centrally d1sposed web portion? disposed in the channel 3 above the conductor 2. An incllned upper edge 8 of the member 4 isadapted for cooperation with a wedge member 9 havlng a similarly inclined face 10. Lugs 11, proectlng from the ends of the portions 3, are
provided with longitudinal grooves 12 for the reception'of transverse flanges 13 of the wedge member 9. The member a is provided with a laterally projecting tongue 14:
that projects through a slot 15 in the mem-,
her 9. lVhen assembled at the factory the members t and 9 are placed in this relation and the tongue 14 is slightly bent in order that the members may be transported as a. unitary structure. In mounting my device, it is placed in the positionshowninFig. 3 and the wedge 9 driven into rigid relation to the lugs 11 and the member 4, afterwhich an extension 17 on the member'i is turned up, as indicated by broken lines, to prevent loosening of the wedge.
When in operative position, the wedging pressure is exerted throughout a considerable portion of the conductor 2 by reason of the engagement of the relatively long web portlon 7 with the same. A readily trans- 7 portable unitary device of extreme simplicity and ruggedness, and which may be readily and firmly mounted with the aid of a hammer or similar tool, is thus provided.
While I have shown and described a particular form of my invention, changes may be made therein without departing from the spirit and scope thereof, as set-forth in the appended claims.
I claim as my invention:
1. An approach for a trolley frog comprising a trolley-conductor-engaging extension member disposed adjacent to the frog and having an inclined plane face, a wedge member engaging the plane face. of the extension member and a member on the frog for cooperation with the wedge member to assist the latter inholding the extension member rigidly against the conductor.
2. An approach for a trolley frog comprising a trolley-conductor-engaging extension member disposed adjacent to the frog, and having an inclinded plane face, a wedge member engaging the plane face of the extension member, a member onthe frog for cooperation with the wedge member to assist prising a trolley-conductor-engaging extension member disposed: adjacent to the frog andhaving an inclined plane face, a Wedge member engaging the plane face of the extension member, said wedge member having an aperture therein, a member on the frog for cooperatlon with the wedge member to assist the latter in holding the extension member againstlthe conductor and a member on the extension member disposed in said aperture and adapted forinterlocking the wedge member and the extension member.
i. A trolley-conductor device comprising a body member having a wedge-receiving portion, a renewable approach member, and
'a longitudinally-slidable wedge to be driven between said members to clamp the approach member in position. i
5. An approach for a trolley frog comprising a conductor-engaging extension member, a member disposed thereon, said members together being'disposed between a portion of the frog and the trolley conductor and means whereby a thrust movement of the one of said members with respect to the other rigidly positions said extension I member.
6. In a device for a trolley conductor, the
combination with a body member engaging the conductor and means for supporting the body member, of a removable member adjacent'and constituting an approach to the body member and adapted to embrace the conductor, said removable member having an inclined plane face, a wedge mcmberengaging the said plane face of the removable member, alug on the body member cooperating with the wedge member to hold the removable member rigidly in position,
and means for locking the wedge member and the removable member in position.
7. A trolley-conductor device comprising a body member of substantially channel.
shape for the reception of a conductor, said 9. A trolley-conductor device comprising a body member vfor the reception of a conductor and a longitudinally-slidable wedge to be driven between the body member and the conductor in the direction of the longi tudinal axis of the conductor for holding the latter in position.
In testimony whereof, I have hereunto subscribed my name this 28th day of Feb. 1918. r V
