Application led February 9, 1912. Serial No. 676,629.

Toall whom 'it may concern:

Be' it known that I, EDMUND M. REDDY, a citizen of the United States, and residing at Ossining, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Ceiling utlet-Boxes, `of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to what are known as, outlet boxes, used in wiring a lire-proof or other building for electric lighting and.

other purposes, and the object thereof is to provide an improved device of this class designed for use as a ceiling outlet box, and in connection with chandeliers and other hanging apparatus, and with this and other objects in view the invention consists in a device of the class specitied, constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specitication of which the accompanying drawing forms a part in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure l is a cross sectional view of a floor and ceiling construction showing the method of using my improvement g-Fig 2 a top plan view of vmy improved outlet box, and Fig. 3 a bottom plan view thereof.

ln the drawing forming part of this specitication I have shown a floor and ceiling construction involving ordinary I-beams a together with the usual concrete l), and t-he fiooring c laid on ashes or similar material c2 placed on the concrete. In forming the concrete part of the floor and ceiling construction a wood frame or support is provided consisting of, boards 1l-(Z2 and d3 placed as shown so as to provide a sort of mold into which the concrete is poured, and this part of the drawing isintended to illustrate the method of using my improved ceiling outlet box e.

rThe outlet box e is rectangular in horizontal section, in the form of construction shown, but may be of any desired shape, and is open at the top when in use, and provided with a bottom e2 having a central depending rim c3 of less transverse dimensions than the body of the box, and preferably abut one fourth the depth of said body of the box. rlhe bottom c2 of the box is provided with spaced holes f which are normally closed by plates f2 inthe usual man-- ner but which, when the box is put in use, are broken out so as to leave the holes f or a part thereof free for the passage of the lead pipes g, which are used in the usual manner, and the end portions g2 of which are bent `downwardly through the box and passed through the openings f two of said pipes being thus shown in the drawing. The center of the bottom of the box is also `provided with a central opening or hole z,

similar to the holes f, but which is intended to serve as an attachment, or means of attaching a threaded plug h2, which plug serves as a support or attachment for an electric, or any other illuminating hanger, lighting device, or other article. The plug h2 may be passed downwardly through the bottom of the box as shown, and may be secured by means of screws h3, or said plug may be secured to the bottom of the box, the only object of said plug, as hereinbefore stated, being to serve as a support and attachment for a chandelier or other hanger.

In practice the box is irst placed in position on the board .or boards d. The pipes g are then placed in position, as shown inFig. 1, after which the concrete is filled in up to` the tops of the -beams a, and in this operation the box e is also filled with concrete, after which the floor-ing consisting of sleepers c3, ashes or other suitable material c2, and the fioor boards c is placed in position, and this completes the operation, of forming the floor and ceiling construction, it being understood that after the concrete has had time to set or become hard, the supporting or molding boards 1l-Z2 and d3 are removed, which operation leaves the bottom rim c3 of the box, the plug 71,2, and the ends vg3 of the tubes g exposed, and a chandelier of any kind may be suspended from the plug ft2 and electric wires passed through the tubes g in the usual manner. It lwill also be understood that my improved outlet box may be used as a combination gas and electric fixture, if desired, all that is necessary being to pass a gas tube through the central opening h in thebottom of the box instead of the a plug h2 or said gas tube may be passed -through said plug.

rlhis improvement provides a perfectly safe, permanent and practical outlet box, and one which may be much more conveniently used in a floor and ceiling construction than' most other devices of this class, as now constructed, and my improved outlet box, used as described, avoids the necessity of cutting in to the concrete in order to place the box, after the concrete Work has been finished.

The bottom rim e2 of the box is secured in position by means of screws i in the form of construction shown, but this maybe done in any desired. manner, and in practice the body of the box, When not in use, may be provided with a detachable cover if desired, and changes in and modifications of the construction hereinbefore described may be made, Within the scope of the appended claim, Without departing from the spirit of my invention or sacrificing its advantages.

of the box being also provided with pipeapertures or' openings, and with a central opening to receive a hanger attaching device. In testimony that Lolam the foregoing as my invention I have signed my name in.

presence of the subscribing 'Witnesses this 8th day of February 1912.

EDMUND M. REDDY.
