OUTLET-BOX.

Specification of Letters Patent.

eowos.

To all whom it may concern:

Be'it known that I, W ILLIAM a citizen of the UnitedStates, and resident ofNew York city, in the-county of New York and State of New York, have invented.

a new and useful Improvement in Outlet- I Boxes; and I do hereby declare the following to be a full, clear, and exact description thereof.

4 My invention relates to an electric outlet box or what is commonly known as a rosette, which is adapted to be fixed to a wall, ceiling or other support for the convenient lead ing out of electric connections. Devices of this character are usually provided with several inlet openings for conduits which lead the conductor into the rosette. It frequently happens that the number of circuits led into the rosette is less than the number of open ings .wit-hwhich the rosette is provided, and

in orderto render the device perfectly safe,

it is" necessary to close the unused openings in order to prevent access of moisture or dust to the interior of the rosette, which might cause short circuiting of the electric connections therein. It is also necessary to so mount the closures or What are commonly known as the knock-out disks in the openings of the'rosette that they may be readily re moved when it isdesired to utilize'more of said openings. My invention, therefore, rclates, pa;r ticul-;ar1y to the construction and manner of mounting these outlet disks in the rosette.

ith this object in View, the invention consists in the construction and arrangement ofparts a preferred embodiment of'which is illustrated in the accompanying drawing,

is which F gure 1 1s a perspective view of a rosette embodyingrny invention; Fig. 2 is a vertical section of a rosette; and Fig. 3 is a bottom plan view thereof with the base plate removed.

In the embodiment of the-invention herein selected for illustration, 1 indicates. a rosette of ordinary and usual form, and'asusual, composed of porcelain. The rosette is provided with the outlet opening 2,:1nd with a p1u'rality,.here four inmumber, of inlet openings 3, for thereception of the ends of 0011-.

duit moldings such as L. These conduits may he of any desired form, but as here shown each consists of a base or. body'portion 5, and a cover portion 6. The bottbmypf the rosette is'closed by a metal plate di disk w A. BoNNnLL,

7, which is attached thereto by means of I screws 8, extending down between the conduit opening 3. The body portion of the conduit may be secured to the base plate 7 by means of screw 9.

In order to maintain the unused conduit receiving opening 3 closed against access of moisture and dust, I provide closer plates or knock-out disks 10 for each opening. These are made of substantiallythe shape, but of somewhat larger area than'the openmg, and :the side and'top walls of each opening are provided with grooves such as 11 into which the knocloout disks 10 may be sprung, or if the base plate has not yet been attached, these plates maybe slid into place. It is to be understood that these knock-out disks are formed of some flexible material such as resilient sheet metal or the like noncombustible material and that they are suf'licicntly flexible or pliable so that they may be flexcdgor bent by suitable tongs or other 'tool for insertion in the openings and when inserted in the openings or removed therefrom, the walls of the openings will not be cracked or otherwise broken or abraded.

lVhile I have shown herein a preferred embodiment of my invention, it is to be un del'stood that the same may be altered in construction and arrangement of parts within the scope of the appended claims.

What-I claim is:

1. An electric outlet comprising abody portion having an outlet opening and one or more conduit receiving inlets, the walls of each of said inlets being grooved and chaoticout disk fdmaach inlet adapted to be sprung into the groove thereof to close the inlet, and a. base plate for the device.

2. An electric outlet device comprising a body portion of porcelain 'or like material, I

curing the conduits thereto, the walls of each.

of said conduit 0 enin s bein rooved a;

closure plate for each inlet of greater area than that of the inlet and adapted to be sprung into closing position with its'edges held in. said groove. I

3. An e ectric outlet device comprising a hollow body portion, having an; outlet opening at. the to. -and an open bottom, a closure plate at the ottom of said device, thelower edge of said body portion having a plurality of notches or recesses for receiving conduits,

a closure plate for each of said conduit openirigs of greater area than of-said' openings and curved to conform to the curvature of the side wall of said body ortion, the walls of said conduit openings ing grooved to receive the edges of said closure plates and to removably hold said plates in position therein.

4. An electric outlet comprising a body portion having an outlet opening and one ved uni;
