To all whom it may concem: Be it'known that I, CARLv H. BIssnLL, a

citizen of the United States, and a resident ofSyracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Plug Receptacle, of, which the following is a specification.

This invention has for its object a plug receptacle particularly applicable f0r elec-.

tric garages or charging stations, which is particularly simple in construction and highly efiicient and durable in use; and the invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed. v

In describing this invention, reference is had to the accompanying drawings inwhich like characters designate corresponding parts in all the views.

Figure 1 is a vertical sectional'viewof' one orm of this plug receptacle.

Figure 2 is a section online 2-2, Fig. 1.

Figure 3 is an inverted plan view partlybroken away of the detached housing showing the position of the sto shoulder coactin" with the shoulders of t e housing. v lligure 4 is a fra entary sectional view of parts shown in ig. 1, the plug inserted in the socket being shown in dotted lines. This plug receptacle comprises generally,

a body, an angular housing swivelled to the body, and a socket located in the housing.

1 is the body which is here shown as having a hooded top and a detachable wall or provided with a hollow nipple 3.

The body 1 is also provided with means as lugs 4 for attachment to a wall or other support and with means as an internally threaded nipple 5 for connection with an electric conduit enclosing the electric wires. The bottom wall 2 rests against a flange 6 extending around the inner face ofthe side walls of the body at the base of a marginal flange 7 skirting the open side of the body. The wall 2 fits into the flange 7 and abuts the flange 6 and is held in position by cap screws 8 threading through the margin of the wall 2 and into lugs 9 onthe interior of the body 1.

1O designates the housing which is angular in general form. As here illustrated the housing consists of a base section 11 swivelled to the nipple 3 and here shown as threadand is provided with-a head 20 which abutscoupling 2 at its bottom, the wall 2 being.

plug and pul ing thereon and an extension section 12 detachably connected to the section 11.

The section 11 is formed with an angular or curved body portion which terminates in a laterally facing tubular nipple 13 in which the extension section;12 threads. A set screw 12" holds the extension from turnq ing. Turning or swiveling movement ofthe housing 10 is confined to a half turn thereof by means of shoulders 14 projecting therefrom from diametrically o posite points and coacting with a stop shoulder 15 on the wall 2, the shoulder 15 being placed in position after the housing is threaded on'the nip 1e 3.

16 designates the socket including a ody' ofinsulatlon fitting in the extension 12 and-7 having shoulders 17. at its rear end which interlock with notches 18 formed in an in- .ternal annular flange 19 provided 'at .the

end of the socket 16.

This socket 16 slidably fits in the nipple 13 against the flange 19 and at 21'against the rear end of the extension section 12. The

socket is held from turning by the shoulders 17 and .notches 18 I and from endwise movement by the head 20 and flange 19 and end 21'of the extension 12. In'assembling, the socket 16 is first placed in the nippic 13 and the extension 12 then screwed into the nipple.

The extension 12 is provided with a suitable hinged cover 22 at its open end and when this cover is lifted a plug as 23 can be inserted in the extension so that the termi-' nals thereof make contact with the terminals of the socket 16.

In operation, a body is placed upon a 95 wall or post or other sup ort and the plug' is carried at the end of wlres and the hous ing can be swung into any angular position to receive the plug and if a, car. or vehicle, the battery of which is being charged, is

started before the plug is withdrawn, the

housing will swing until the wires connected to the plug pull in a straight line On the the plug out of the socket. What I claim is: r 1. An electric receptacle comprising a conduit outlet box for service wires, the box having an opening in one side, a coverfor the opening having a nipple on its outer side, and a housing having a portion swivelled to said cover on said nipple, for receiving the service wires passing through the opening from the box, an electric receptacle located in the housing for connecting to the service wires through the swivel joint, and means located outside of the housing and the nipple for attaching the cover to the box, substantially as and.

' threading on the nipple and havingperipheral shoulders, and a shoulder carried by the removable wall and coacting with theformer shoulder to limit the turning movement of the housing, substantially as and for the purpose set forth.

4. A plug receptacle comprising a housing including a base section, and an extension section detachably connected together, the base section being formed with. a shoulder opposed to and spaced from the inner end of the extension section, and a socket extending into the extension section from the inner end thereof and having means interposed between the shoulder and the opposing end of'the extension section for holding the extension section from endwise movement, substantially as and for the purpose specified.

5. A plug receptacle comprising a housing including a base section, and an extension section detachably connected together the base section being formed with a shoulder opposed to the inner end of the extension section, a socket extending into the extension section from the inner end thereof and having means interposed between the shoulder and the opposing end of the extension section for hol ing the extension section from endwise movement, the socket also having means for interlocking with the base section to prevent turning thereof, substantially as and for the purpose set forth.

6. A plug receptacle including ahousing comprising an angular base section, and a tubular extension section, the base section having a laterally facing-.ni ple, and an internal annular flange at tie base of said nipple and the extension extending into the nipple and having its inner end opposed to and spaced from the flange, and a socket extending into the inner end of the extension section and having a portion thereof interposed between the flange and the end of the extension section, substantially as and for the purpose described.

7. A plug receptacle including a housing comprising an angular base section, and a tubular extension section, the base section having a laterall facing nipple, and an internal annular ange at the base of said nipple and the extension section extending into the nipple and having its inner end opposed to and spaced fromthe flange, and a socket extending into the inner end of the extension section and having aportion thereof interposed between the flange and the end of the extension section, and also having means for interlocking with said flange to prevent turning of the socket, substantially as and for the purposespecified.

In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of Onondaga and State of New York, this 7th day of June, 1918.

CARL H, BISSELL.
