. FACE-PLATE FOB FLUSH RECEPTACLES.

Specification of Letters Patent.

Patented Apr. 1(1 1917.

To all whom 2'25 may concern.

Be it known that I, Gnonon B. TrroMAs, a citizen of the United States of America, and residing at Bridgeport, in the county of Fairfield and State of Connecticut, have in vented a certain new and useful Improve ment in F ace-Plates for Flush Receptacles, of which the following is a specification.

My invention relates to face plates for flush receptacles and particularly to the mounting of the doors in the face plate which normally obstruct the aperture lead ing into the chamber of the associated re' ceptacle.

Referring to the accompanying drawings,

Figure 1 is a perspective of a face plate in which my invention is illustratively embodied;

Fig. 2 is a longitudinal section therethrough showing one of the door wings opened;

Fig. 3 is an inverted plan of the face plate; and

Figs. 4 and 5 are cross sections through details of the door construction.

The face plate here shown is of the type commonly used in association with receptacles for attachment plugs of the Chapman type and comprises the plate proper 10 con trally apertured at 11 to permit the passage of the plug therethrough into the associated receptacle (not shown). This aperture is normally obstructed by a pair of door wings 12 adapted to swing open to permit the insertion of the plug and recessed at their meeting edges at 13 to accommodate the neck of the attachment plug and the lead wires which are connected therethrough.

In its main features the face plate is of well-known type and the present invention is confined to the hinge mounting of the door wings 12 so that when openthey extend substantially at right angles to the plane of the face plate. To this end each'wing 12 of the door is recessed at 14 to form a pair of short legs 15 straddling a broad tongue 16 projecting into the area of the central aperture 11 formed in the plate. Each door wing 12 is hinged to the face plate at opposite ends of the aperture 11 by means of pins 1'3 lying in registering grooves 18 and 19 cut in the inner face of the plate 10 and each 15 of the door and secured in position by pinching over the metal of the door and plate at 20 and 21 respectively to grip the hinge pin. The location of the grooves 18 and 19 and the pivot pin 17 is so predetermined that when the door wing 12 is swung outward into open position the tongue 16 abuts against the outer face of the wing 12 and halts the latter when it has reached a position substantially at right angles to the plane of the plate.

Any suitable means may be employed to halt the plates in their closed position. For instance, a metal disk 22 centrally perfo rated may be seated in a recess 23 formed in the plate 10 at the margin of the aperture 11 and in such position that a portion 24 thereof projects into the area of the opening. The disk is retained in position by a rivetlike stud 25 passing through the central opening in the disk and spread at its lower end over the surrounding inner margins of the disk. Corresponding recesses 26 are formed in the margins of the door wings 12 so that when the latter are closed and bear against the plate 24 they lie substantially flush with the outer face of the plate 10.

The construction indicated is extremely simple to manufacture and at the same time affords a workmanlike and efiicient doormounting so arranged as to prevent the door wings from turning back farther than substantially to the position shown in Fig. 2, namely, one in which they stand at substantially right angles to the plane of the plate.

Various modifications of construction may be devised to accomplish the same result without departing from what I claim as my invention and of course it is not intended as a limitation of my invention that the latter is embodied in a face plate of the type having a pair of door wings, since it might with equal facility be embodied in a face plate having but a single door.

I claim as my invention A face plate for flush receptacles having acentral aperture and a door normally obstructing the same, a stop tongue projecting from the body of the plate into said aperture In testimony whereof I have signed my and legs on the door straddling said stop name to this specification, in the presence of tongue and hinged to the door body in such two subscribing Witnesses. position that said stop tongue engages the GEORGE B. THOMAS. outer face of the door and halts the latter at Witnesses: right angles to the plane of the face plate, G. W. GOODRIDGE, substantially as described. H. M. WIoHnRT.
