A purpose of this invention is to combine a lighting fixture in conjunction with a ventilator. It is a well known fact that heated air rises and therefore the air heated by the lamp provided by this invention will, on ri ing and passing through the ventilator, create a draught, assuring perfect circulation.

This invention is useful in bathrooms, showers, tub-alcoves, kitchens and the like. The device is illustrated on the drawings herewith, showing it within a ventilating hood. It is to be understood that the use of the device is in no way limited.

One of the objects of this invention is to provide a combination ventilator and light fixture which is simple in construction and operation, and which retains its eficctiveness as an ornamental fixture.

Another object of this invention is to provide a combination ventilator and light fixture, the lighting means and ventilating means of which are independently operatable.

A still further object of this invention is to provide a combination ventilator and light fixture, the working parts of which are invisible, thus making it easier to keep clean.

A still further object of this invention is to provide a simple economical and effective combination ventilator and light fixture, avoiding the necessity of separate fixtures for light and ventilation heretofore used.

This invention will be readily understood from the following detailed description thereof, taken in connection with the accompany ing drawings in which:

Fig. 1 is a side elevation embodying a preferred form. of said invention, showing the shutter in its closed position.

Fig. 2 is a plan view of Fig. 1, omitting the socket and light bulb.

Fig. 3 is a vertical cross-sectional view taken on line 33 of Fig. 2, indicating the socket and lightbulb in dotted lines, and showing the shutter in its open position.

Fig. 4 is a side elevation of another embodi ment of the device, showing it in position within a ventilating hood.

Fig. 5 is a bottom plan view thereof.

Fig. 6 is a sectional view taken on line 6-6, Fig. 5."

Serial No. 239,327.

Fig. 7 is a fragmentary sectional detail, taken on line 77 of Fig. 5.

Referring now more in detail to the drawings and especially to Figs. 1, 2 and 3, which illustrates one form of the device particularly adapted for bathrooms, kitchens, tubalcoves, showers and the like, the numeral 10 represents the main body of my device, being annularly shaped as clearly illustrator in the plan view Fig. 2, and conforming in profile to that illustrated by the vertical cross-sectional view in Fig. 3. The member 10,1naybe a casting or otherwise formed. The upper raised portion 11, of the member 10, is provided with a plurality of evenly spaced slots or ports 12, and is adapted to carry in juxtaposition to its upper surface the circumferentially slidable shutter 13, which in turn carries a series of slots 14, the spacing num her and size of which preferably corresponds to those in the raised portion 11, of the member 10, thus assuring the coinciding of both series of slots when the device is in its open position as clearly illustrated in Fig. 3, of the drawings. Figs. 1 and 2 show the shutter in its closed position, the slots in the shutter 13, and those in the raised portion 11 of the casting 10 being staggered.

The casting 10, is provided on one sine with a slot 15, illustrated in Fig. 3, to receive the pin portion 16 of the member 17, said pin portion extending upwardly therethrough, to engage with the boss 18, of the shutter 13, in any suitable manner, preferably screw threaded into the boss 18. The lower end of the member 17 is provided with an opening 19, to receive the chain 20, rigidly secured in place bv the retaining screw 21, and passing I freely through the

guides

22 and 23. shown in Fig. 1, said guides tightly engaging with the main body 10.

The circumferentially moving shutter 13, is held in uxtaposition with the upper surface of the raised portion 11, through an outwardly extending boss 25, on the shutter 13, 95 and the guide 26 of the main casting 10.

The holes 27 provided in the casting 10, F 2, are'for convenience in mounting the fixture.

The extreme lower portion of the casting 10, is provided with an inwardly extending flange or shoulder 28, to support the upper member 29 of the socket 30.

In order to avoid unnecessary expense due to complication of form, the annular member 31 may be conveniently and economically spun from brass or the like and fastened to the lower end of the casting 10 in any suitable manner, being provided on its lowermost extremity with an enlarged screw threaded por tion 32, having around the circumference of its inner wall a plurality of vertically disposed stops 33.

The threaded retaining ring 34 fits over the bowl 35, and is screwed onto the threaded portion 32, tightly engaging the bowl with the stops 33, through a flange 36 on the retaining ring, and an outwardly extending ring on the bowl.

Numeral 36 designates the lower member of the socket 30, carrying a light bulb, said member passing through the opening 37 to engage with the upper member 29.

Numerals 38 and 39 are current supply wires. It should be clearly understood that the lighting means and the ventilating means operate entirely independently of each other.

A rubber gasket 39 is provided between the flange 36 of the retaining ring, and the outwardly extending ring on the bowl to eliminate the admission of steam or the like endangering a short circuit, while the upper surface of the socket 29 may be completely covered With a layer of wax or the like pre venting the admission of any moisture at the top.

Figs. 4, 5, 6, and 7 illustrate a modification of my invention especially designed to fit within a ventilating hood commonly used over kitchen stoves, but is not limited to such utilization.

Referring to Figs. 4, 5, 6, and 7, the reference character 40 designates the main body member or base of the structure. and for simplicity of illustration is shown within a ventilating hood or the like 41.

The member 40 is provided with a circular opening 42, clearly illustrated in Fig. 6, of the drawings, and carries on its lowermost surface 43 a downwardly extending annular flange 44. said member 40 having on either side of the flange, a plurality of transverse slots or openings 45 therein, shown in Fig. 5. and carries on its upper surface 46, a shutter 47 also provided with a circular opening 48 and transverse slots 49 therein. said opening and slots being preferably identical in size and shape to those in the member 40, and adapted to coincide with the same when the shutter is in its extreme open position. The shutter is horizontally slidable on the upper surface 46, of the member 40, and is guided thereon by a number of upwardly extending guide pins 50, on the member 40, engaging with slots 51 in the shutter.

The holes 52, in the member 40, are simply a suggestive means for conveniently mounting the device.

Referring especially to Fig. 6, the member 40 is provided with

slots

53 and 54 to receive

pins

55, 56, passing upwardly therethrough to tightly engage with the shutter 47, in any suitable manner, the lower end of said pins icing adapted to carry retaining

nuts

57 and 58, thus assuring positive engagement of the shutter 47, with the upper surface 46, of the member 40. The retaining nut 57, carries a chain or the like, rigidly fastened thereto in any suitable manner, said chain passing freely through

guides

59 and 60, tightly secured to the member 40.

One end of the annular member 61, is adapted to fit over and tightly engage with the downwardly extending ring 44, to abut against the lower surface 43 of the member 40, and is provided with an enlarged screw threaded portion 62, carrying around the circumference of its inner wall a plurality of vertically disposed stops 63.

A threaded retaining ring 64-, is adapted to fit over the bowl 65, being screwed onto the threaded portion 62, tightly engaging the bowl with the stops 63, through a flange 66, on the retaining ring, and an outwardly extending ring on the bowl. An annular gasket 67 may be placed between the flange 66 and the ring on the bowl.

One end of the annulus 68, is allowed to tightly engage with the inner wall of the screw threaded portion 62, the other end being provided with an inwardly extending flange, or supporting shoulder 69, for the electrical means, which consists preferably of a two piece electrical receptacle 70, the member A, being adapted to screw thread into the member B. and carries a light bulb or the like, said members A and B abutting opposite sides of the flange 69. Inasmuch as the specific construction of the electrical receptacle forms no part of my invention, I have merely indicated the general outline of the receptacle in dotted lines. The inner surface 71 of the annular supporting member 68 may be conveniently used as a reflector.

Numerals

72 and 73 are current supply wires.

A protective cap or cover 74 for the electrical means, fits over an upwardly extending ring 75 on the shutter 47 and is tightly en gaged with the shutter 47 through screws 76, or the like, said cap having a slot 77 or outlet for the current supply wires.

It should be clearly understood also in this modification of my invention that the electrical means and the ventilating means are independently operatable.

From the foregoing description considered in connection with the accompanying drawings, the construction, 0 eration and advantages of this device will e apparent.
