ELECTRIC PLUG REGEPTAGLE.

Application filed February 7, 1920. Serial No. 356,899.

To all whom, it may concern.

Be it known that I, CARL H. BISSELL, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Electric Plug Receptacle, of which the following is a specification.

This invention relates to plug receptacles and has for its object a plug receptacle detachable forconduit outlet boxes and provided with a cover, which also serves to particularly simple in construction, highly etlicient and durable in use, and rea'di v applied to the conduit outlet boxes.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed. 5

In describing this invention, reference is had to the accompanying drawings, in which like characters designate corresponding parts in all the views. p Figure 1 is a plan viewof this plug receptacle and plug, the conduit outlet box being also shown.

' Figure 2 is an elevation of parts seenin Figure 1.

Figure 4. .is a vertical sectional view, partly in elevation, taken on the plane of line 4-4, Figure 1.

Figure 5 is an. inverted plan view of the plug.

This plug receptacle comprises generally 1 "a body having 1 an entrance opening by meansofwhich the plug with its terminals.

. carried by rods 9 extending into the tubu lar parts-7 and having shoulders 10 at theif lower ends. The springs 11 which serve to actuate the cover toward its closed position are located in thetubular parts 7 and are interposed between the shoulders 10 and the top walls of said tubular parts The body is provided with a suitable gasket 12 around the "opening 2 and on which the cover 8 normally seats and also on which the body 13 of the plug rests.

The plug is constructed to move laterally under the cover 8 .after the same has been of the springs 11 and, as here shown, is in the form of a circular box having an outwardly radially extending nipple. 14, or handle 14, for the body being closed at its top and edges and being open at its bottom. Central and outerterminals15 and 16 are supported by a base 17 of insulation in the body 13 of the plug and the terminals are exposed through the open side thereof, the base and terminals being here shown as held in position b the ring 18 threading in the open side 0 the bod 13- warolly to engage its inner and outer ter- 9 minals 15- and 16 with the central and

outer terminals

4 and 5 of the plug receptacle, the cover being clamped against the upper side of the plug by reason oft-he springs 11. Owing to the rin -sha ed body 1 of the receptacle and the epen ing tubular members 7, the body. is readily mountable upon the-open sideof a conduit outlet. box 20 which box is cylindrical in general form and has laterally extending nipples 21 for connection with electric conduits for en-' closing the

service wires

22 and 23 which are connected to the inner and

outer terminals

4, 5. The body of the plug receptacle is secured to the box in any suitab e manner as by screws 24 eiztending through lugs 25 in the ring-shaped body 1 and boxes and further in that it provides n1eans by which the lug is firmly engaged with the socket wit iout providing a comparatively deep socket or under plug.

What I claim is:

1. An electric plug receptacle comprising a body having an entrance opening and a seat around the opening and a cover normally resting on the seat, in combination with a plug receptacle movable into the receptacle under the cover, the cover being movable rectilinearly to and from the seat and into engagement with the plug when the plug is in the entrance opening under the cover and a spring for moving the cover rectilinearly against the plug.

2. An electric plug receptacle, comprising a body, formed with an entrance opening, and a seat around the opening, a cover movable rectilinearly toward and from the opening, and having a portion engaging the seat, and a spring for moving the cover into closed position, in combination with a plug movable under the cover and into the opening, the-cover being arranged, so'tha't, it presses; the plug into the receptacle.

3.- Anelectric plug receptacle comprising a body formed with an entrance opening, a cover movable toward and from the opening and having guide rods on opposite sides of the'opening, the body being formed with guide passages for the rods, and springs acting on the rods to move the cover rectilinearly into its closed position, substantially as and for the purpose described.

4. An electric plug receptacle comprising a body formed with an entrance opening, a cover movable toward and from the open ing and having guide rods on opposite sides of the opening, the body being formed with guide passages for the rods, and springs acting on the rods to move the cover rectilinearly into its closed position; in combination with a plug movable laterally under the cover and in position to be pressed rectilinearly by the cover against the receptacle, substantially as and for the purpose specified.

5. The combination with a conduit outlet box formed with an opening in one side of a plug receptacle comprising a body mounted in the open side of the box and guides depending from the body on the outside of the box, a cover closing the body and having projections movable in said guides, springs in the guides and acting on the projections to hold the cover in its closed position and in en agement with the plug, the plug being .n'iova lile' under the cover in position to be engaged and pressed into the receptacle by the cover.

6. The combination with a conduit outlet box having an opening in one side, of a plug receptacle. comprising a body mounted on the open side of the box, and having an opening, terminals carried by the body, the body also having tubular parts extending on opposite sides of the box, acover for the opening in tl1e body, and springs located in the tubular parts and acting on the rods, rods depending from the cover and extending into the tubular arts and a plug movable laterally'under tlie cover and having terminals for coacting with the terminals of the receptacle, substantially as and for the purpose specified.

7. An electric plug receptacle, having an entrance opening, a plug for coacting with the receptacle, and. a cover movable rectilinearly toward and from the opening, springs for moving the cover toward closed position, and such cover pressing on the "plug in the direction of the axis of the plug when the plug is in the receptacle. In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of Onondaga and State of New York, this 20th day of December, 1919.
