The present invention improves upon the prior ~ ~
art by providing an electrical pipe fitting having an ~ -integral grounding fixture which is specifically designed to be used in an electrical conduit system to bring such a system into compliance with municipal code requirements.

A raised portion extends from the hollow tubular member and has an aperture for receiving and securing a grounding wire.
Preferably, a screw is used to secure the grounding wire within the aperture. The screw extends into the iaperture of the raised portion of the fitting and presses an uninsulated portion of the grsund wire against a wall of the aperture to establish a ground path between the grounding wire and the electrical pipe.
Additionally, a clamp is preferably disposed adjacent the aperture for securing an insulated portion of the ground wire against the hollow tubular member.
The raised portion can be formed integral with the tubular member or integral with a sleeve which extends over the tubular member.
The electrical pipe ~itting can either be a straight section or, alternatively, can include an angled corner, such that the ends of the fitting are perpendicular to each other. A removable cover is preferably provided in the embodiment of the invention with the angled corner to facilitate access to the electrical wire. A frictional lock is provided to prevent unintentional dislodging of the removable cover.
Advantageously, the fixture of the present invention is simple, economical, easily installed and provides secure grounding at the point of connection.

Referring to Fig. 2, the present invention relates to an electrical pipe fitting in the form o~ a hollow tubular member 34 for receiving electrical wire.
A raised portion 36 extending from tubular member 34 has an aperture 38 for receiving a grounding wire. A screw 39 extends into the aperture and presses an uninsulated portion of a grounding wire against a wall of aperture 38.
The hollow tubular member 34 is adapted to be coupled as an intermediate section of a grounded electrical pipe. Tubular member 34 has a first end 40 which fits snugly inside the end of a pisce of electrical pipe or conduit. A number of small ridges 41 extend at least partially circum~erentially around the end 40 to assist in securing the end inside the conduit. When the end 40 is inserted fully, the conduit end comes to rest against a collar 42 on the tubular member 34. The collar 42 has raised bumps 43 which~afford a better grip on tubular member 34.
A plat~orm 44 disposed adjacent raised portion ~ -36 extends laterally with respect to the tubular member and includes a U-shaped~recess 46 for receiving the grounding wire. A wire clamp bracket 48 with an opposing . -2~ ~8392 -U-shaped recess 44 is secured onto platform 44 with screws 47, the wire being held in place between recesses 46 and 49. ~ -~
The tubular member 34 is also adapted to be ;
removably connected to an electrical receptacle bsx. As ~ -shown in Fig. 8, a second end 50 of tubular member 34 can :~
be inserted through an opening 29 in the receptacle box : :
25. The receptacle box 25 has a plurality of removable disc-shaped covers 26, each of which can be easily punched out to provide an aperture for receiving the second end 50 of tubular member 34. The second end 50 of :. :
tubular member 34 includes threads 51 which mate with ~ - -threads 53 of a collar 52 to secure the fitting within the receptacle box. The electrical receptacle box also includes threaded tabs 27 for securing a face plate, and apertures 28 for receiving screws to secure the :
receptacle box within a wall or other desired structure.
A second embodiment of the invention is shown in Figs. 3 and 9, wherein like reference numerals are used to d~signate like elements in Figs. 2 and 8. In the - :
second embodiment, the raised portion 36 and platform 44 are disposed on a separate metal sleeve 60, a portion of : :~
which, identified by reference number 64, extends over --tubular member 34. Sleeve 60 has a hollow collar :portion, perpendicular to portion 64, through which the second end 50 of tubular member 34 is inserted, prior to being inserted within the receptacle box.

The second embodiment of the invention shown in Figs. 3 and 9 also differs from the first embodiment in that electrical pipe fitting 32 comprises a straight tubular member 34 for accommodating electrical wire, but does not include a male end 40 extending therefrom which fits into another section of electrical pipe. Rather, tubular member 34 is a female piece and receives a section of electrical pipe. A screw 55 extends through an aperture 56 in tubular member 34 for securing the fitting to the section of electrical pipe inserted therein. Tubular member 34 includes ridges 57 spaced ~
