*"i l a I'I /6 i I A5 I l l l I nventm' Attorney Patented May 21, 1935 UNITED STATES PATENT OFFICE ELECTRICAL OUTLET AND CONNECTER FOR RAILWAY TRACKS 1 Claim.
This invention appertains to new and useful improvements in electrical outlets and connecters for electrical cables and more particularly to such a device for railway use to accommodate the usual Parkway and similar type cables.
An important object of the present invention is to provide a combined outlet and connecter which is of such construction as to permit its use at a lower cost than the combined price of material and labor required in installing the old types.
During the course of the following specification and claim, other important objects and advantages of the invention will become apparent.
In the drawings:
Figure 1 is a side elevational view of the device.
Figure 2 is a side elevational view of the device at a point substantially ninety degrees removed from the side portion shown in Figure 1.
Figure 3 is a vertical sectional view through the structure.
Figure 4 is a cross sectional view through the cap.
Figure 5 is a side elevational view of the installation box assembly.
Figure 6 is an inside elevational view of one of the plugs.
Figure '7 is a perspective view of one of the plug liners.
Figure 8 is a top sectional view taken substantially on line 8-8 of Figure 3.
Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents the usual conduit pipe through which the Parkway cable 6 is disposed. The outlet end of the conduit 5 is split longitudinally as at I and has a clamp 8 thereon whereby this end of the conduit can be snugly clamped against the contact block assembly shown in Figure 5. This contact block assembly has a head portion a and a reduced extension 2), the extension and head being connected by a tapered neck 0, all of which is shown in Figure 5. The extension b projects into the end of the conduit 5 and a dielectric bushing 9 is interposed between the same and the inside of the conduit 5. The bushing 9 has a flared extension III which is disposed along the tapered neck portion c of the contact block assembly.
Between the contact sections and d are the plates l|--I| of insulation. The contact block assembly has a bore extending longitudinally therethrough for receiivng the outlet end of the cable 6. The insulation plates II have longitudinally extending grooveways I2 thereon to fit into this bore and completely insulate the cable from the contacts. The conductors l3 from the cable extend out of the end of the cable and are connected to the top of the blocks c-d by binding screws M. A pair of sockets l5--l5 are provided in the sides of the blocks cd for receiving the usual conventional type connecting plugs "5 having the track wires I! attached thereto.
It will be observed that the head portion a of the contact block assembly is provided with a cap l8 which fits over the head portion a and this cap is provided with an annular band I9 of insulation at its inner side for spacing the cap from the said head a.
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having described the invention, what is claimed as new is:
A combined outlet and connecter comprising a conduit containing a cable having oppositely disposed slits in one end thereof, a pair of semicircular shaped contact blocks partially disposed in the slit end of said conduit, a band around the slit end thereof for securing said blocks in position, each of said contact blocks being provided with oppositely disposed semi-circular shaped bores therein for the reception of a cable, insulating members between the cable and the blocks comprising a longitudinally extending central portion semi-circular in transverse cross section having laterally extending integral side portions for disposition between the inner faces of the block, oppositely disposed bores in the sides of each of said blocks, and contact pins lon- 45 gitudinally disposed in said blocks extending from the upper faces thereof and having a. portion terminating in the bores.
