This invention provides a ceiling ventilator constructed and arranged to carry an electric light or electric light fixture and thereby provide a combined ceiling ventilator and electric light fixture; and the objects and nature of the invention will be readily understood by those skilled in the artin the light of the following explanations of the'accompanyi'ng drawings that illustrate'what'l now believe to be the preferred mechanical expressions or embodiments of my invention from among other forms, constructions and combinations within the spirit and scope thereof.

An object of the invention is. to provide a combined ceiling ventilator and support or carrierfor electric lights or fixtures to gain the advantages incidental to the provision of a common support or carrier for both the ventilator and the electric fixture whereby both can be arranged at the central portion of the ceiling of a room and whereby the heat generated'by the electric bulbs can be rapidly carried off and the ventilation of the room will be promoted by the air heated by the bulbs, and further to so construct'and form the ventilator as to carry the electric wire terminal box and to enclose and protect the electric wires leading to the electric fixture, and further to provide ceiling ventilator improvements whereby such ventilators can carry electric fixtures and provide for safe wiring therefor.

With these and other objects in view, my invention consists in certain novel features in construction or in combinations and arrangements as more fully and particularly set forth and specified hereinafter.

Referring to theaccompanying drawings, forming part hereof I Fig. 1 is a perspective view of acombined ceiling Ventilator and electric fixture support; in accordance with my invention, secured in or to a ceiling and carrying anelectric fixture.

Fig. 2 shows in perspective, the combined ceiling ventilator and electric light support carrying a differently constructed or different electric light fixture from that shown 'Fig. 1.

Fig. 5 is a top plan of a portion ofthe ventilator.

Fig. 6 is a vertical section on the line Fig. 5, the light fixture of Fig. 2 being shown, and the light pendants being omitted.

Fig. 7 is a detail cross section onthe line 7-7, Fig. 6.

To provide room or enclosure and to reduce the temperature adjacent to the electric light bulbs of a ceiling electric light fixture, I form avertical ceiling b, above the electric fixture, leading into the air space or into an ofi'take flue above said ceiling.

Around the lower end of this outlet opening a, I secure a ventilator and electric fixture supporting vertically open annulus 1, as by securing means 2, entering the ceiling supports 0, although I do not wish to so limit my invention.

This strong metal annulus 1, surrounds the air outlet a, and forms, in effect, a portion of the surrounding wall thereof, and at its lower end provides a horizontal facing flange approximately fiush with the ceiling and concealing the joint between the annulus and the hole through the ceiling.

The bottom face or lower end of this annulus, also provides an annular seat or surface 1, against which the circumferential portion of the ventilator closure disk 3, can seat or close upwardly to close the annulus against upward air fiow.

The disk 3, isv horizontally disposed in the room below an alined with the annulus and is carried thereby. The exposed bottom face of this disk is preferably ornamental and exposed and accessible in the room from below ,for operation to move the disk upwardly "to restrict or stop the outflow of air through-the annulus or downwardly to promote the outflow of air. This up and down movement of the disk is preferably accomplished by rotation thereof in opposite directions through the medium of a screw threaded connection for the proper ventilation of a air opening or outlet a, through the room usually integral with radial arms 6, usually integral with the annulus 1. The upperend of the spindle extends through hub 5, and is clamped thereto, as by upper and lower nuts 7 and spacing sleeve 7.

.The spindle 4, is utilized as the hanger or immediate support for any suitable electric fixture or so-called electric light, such as 10, Figs. 1 and 4, or 11, Figs. 2, 3, 6 and 7 and to carry the terminal box 12, and enclose and protect the electric light wires 13, leading from the house wiring system through said box to the light bulb sockets 14, of the electric light fixture.

To this end the spindle 4 is formed of a strong metal or other suitable-material tube with the longitudinal bore 4 thereof, open at the ends, for the passage of the electric wires from the terminal box or of a flexible metal protecting tube carrying said wires, and from which the wires can be distributed to the respective sockets of the hanging electric light fixture.

The terminal box 12, is supported by and rises from and is screwed onto or otherwise fixed on the projecting upper end of the spindle 4, so that the open upper end of the bore of the spindle opens into the box. The terminal box thus upstands on the upper end of the spindle in the air space or flue above the ventilator and yet is accessible up through the annulus secured to the ceiling. The wires from the house wiring extend into and are secured in the terminal box in the usual manner, and are threaded or otherwise carried from the box down through the spindle and out at the lower end thereof for distribution and coupling to the fixture when applied.

The lower end of the spindle 4 is variously equipped for hanging the electric light fixture therefrom and for leading the electric wires thereto.

For instance, in Figs. 1 and 4, the bottom stop nut 8, extends downwardly from transversely open eye or loop 8 and depending tubular threaded nipple 8 through which the electric wires can continue downwardly from the spindle bore. A depending sup porting eye or loop 16, having a hollow threaded nipple is attached to and supported from the nipple 8*, by a tubular screw threaded coupling, and if so desired an ornamental canopy 17 can be secured between the eye 16 and the nipple 8 The eye 16, forms the support for the depending hanger or other shank 18 of the electric fixture 10. The electric wires pass from spindle 4, through open loop 8 the hollow nipple 8 and the nipple of eye 16, down the hanger 18 for distribution to the sockets 14.

Where a fixture of the type of that shown at 11, Figs. 2, 3, 6 and 7, is employed, the horizontally disposed ornamental disk-like frame 20 from which the sockets '14, are suspended, is clamped to the nipple 8 of the nut 8, on the lower end of spindle 4, by the screw 21, and the wires 13, are passed from the lower end of the spindle bore laterally through the open loop 8 of said nut along channels in the upper side of disk 20, to vertical holes therein leading downto the sockets 14.

The spindle 4 is adapted to carry and provide protected wiring facilities for various kinds of electric light fixtures, particularly those of the general chandelier type.

The ventilator provides for protected wiring in accordance with known municipal and governmental requirements, while the electric bulbs are so arranged with respect to the ventilator as not to interfere with the accessibility of the disk 3, from below, and its operation to control the outflow of air from the room, and also the relative arrangement of the electric bulbs and the ventilator is such as to promote the direct upflow of air to and through the ventilator which aids in the ventilation of the room and in preventing a dangerously high temperature in the vicinity of the light bulbs. i

It is evident that various departures and modifications can be resorted to without departing from the spirit and scope of my invention and hence I do not wish to limit my invention to substantially the disclosures hereof.
