ATTORNEYS United States Patent TELEPHONE BOOTH LIGHTING AND VENTILATING MEANS Percival H. Sherron, Jamaica, NY.

Application September 1, 1955, Serial No. 532,001

3 Claims. (Cl. 98-39) This invention relates to lighting and ventilating means for a telephone booth and, more particularly, to a telephone booth ceiling structure which includes means for producing air flow, means providing a light source and means for transmitting air flow and light into the telephone booth below the ceiling structure.

In my copending patent application Serial No. 307,630, filed September 3, 1952, I have disclosed a telephone booth provided with a hinged ceiling panel through which access may be gained to apparatus in a ceiling chamber above the ceiling panel when the ceiling panel is hinged downwardly. This arrangement facilitates access to illuminating means mounted in the ceiling chamber. It is customary to mount an air blower in the ceiling chamber of a telephone booth and to provide an inlet to the ceiling chamber from the exterior of the booth and an outlet from the ceiling chamber into the interior of the booth in order that a circulation of air may be provided through the booth when it is occupied. Heretofore, the air blower has generally been mounted at a location displaced from the center of the booth ceiling and, when a hinged ceiling panel is employed, displaced from the" hinged ceiling panel. This was done generally because of the fact that illuminating means, desirably positioned centrally in the ceiling chamber, and above the hinged panel when a hinged panel is employed, prevented, by its physical presence, the mounting of the air blower in a region located centrally of the ceiling chamber. Furthermore, the use of a transparent panel in the displaceable portion of the ceiling panel led to positioning the blower adjacent to some other region of the ceiling through which there was provided opening for the passage of air.'..

These heretofore employed arrangements had the disadvantage of positioning the fan in. relatively inaccessible locations within the ceiling structure and giving rise to a delivery of air into the telephone booth at a location displaced from the most desirable location, namely, the central portion of the ceiling thereof which would be directly over the head of a caller in the telephone booth.

It is the object of this invention to provide a ceiling structure in a telephone booth in which an air blower or fan is mounted substantially centrally in the ceiling structure over an air grill in the central portion of a translucent displaceable portion of the ceiling panel. With the blower in this arrangement, illuminating means are positioned around the air blower and over the region of the transparent panel not cut away to make provision for the air grill.

These and other objects of the invention relating particularly to details of construction thereof will become evident from the following description read in conjunction the accompanying drawings in which:

Figure l is a perspective view of a complete telephone booth embodying the invention;

Figure 2 is a top view of the booth shown in Figure l with the top cover removed;

2,925,770 Patented Feb. 23, 1960 Figure 3 is a fragmentary vertical section through the booth taken on the trace 3-3 shown in Figure 2 show ing a hinged ceiling panel hanging open; and

Figure 4 is a fragmentary vertical section through the booth taken on the trace 3-3 shown in Figure 2 and showing another embodiment of the invention from that shown in Figure 3 with the hinged ceiling panel in the closed position.

In Figure 1 there is shown a telephone booth including corner posts 2 mounted upon a base member 4 and supporting side panels 6 and a conventional door assembly 8. Lintels 10 extend between the corner posts above the side panels 6 and the door assembly 8.

Positioned behind the lintels 10 and supported from the upper edges thereof is a ceiling fan assembly indicated generally at 12 in Figure 2. The ceiling structure includes four vertically extending sides 14 having outwardly turned flanges 16 at their upper ends adapted to rest on horizontally extending flanges formed on the inner legs of channel members 18 resting over the lintels 10. The structure thus far described is substantially identical to that described in greater detail in my abovementioned copending patent application.

A pair of plates 17 and 19 extend horizontally between the lower edges of the vertically extending side walls 14 of the ceiling structure. These plates 17 and 19 extend transversely of the booth as viewed from the front thereof. A hinged ceiling panel 20 is positioned between these plates 17 and 19 and is mounted in a frame 22 which is hingedly connected to the plate 19.

The panel 20 is preferably formed of a translucent material and preferably a translucent plastic material which is less susceptible to breakage than glass. A louver assembly 24 providing suitable grill openings and also providing for diffusion of flow of air is mounted in the panel 20 at substantially the center thereof.

A channel member 26 is supported on the flange 16 of the ceiling structure and extends transversely of the booth from the front to the rear thereof. A fan motor 28 is mounted on the channel 26 and drives fan blades 30 which are fixed to the lower end of the motor shaft extending downwardly from the motor 28. The motor 28 and the fan blades 30 are positioned to be directly above the fan grill 24.

Also supported from the channel 26 and from an angle member 32 are a pair of circular lamp tubes 34, The lamp tubes are positioned so as to surround the fan 30, thus light emanating from the lamp tubes passes downwardly through the translucent panel 20 around the grill 24 without there being cast upon the translucent panel 20 an obvious shadow of the fan motor 28 or the fan blades 30. This arrangement of the lamp and tubes 34 and the fan motor 28 provides for easy access to these parts when the hinged ceiling panel is in the open position as shown in Figure 3.

Intake louvers 36 are provided in the rear lintel panel anda grill screen 38 is mounted over an opening in the rear wall 14 of the ceiling structure. The louvers 36 and the grill screen 38 are connected together by a suitable air duct 37 and provide for the inflow of fresh air to within the ceiling structure from which the fan blows air downwardly through the grill 24 into the telephone structure.

in the door post and positioned to be actuated upon closure of the telephone booth doors in order to initiate operation of the fan when a caller is in the telephone booth. If desired, a switch may be located withinconvenient reach of theyoperator such as, for example, the switch 42 which is located above the telephone mounting panel 44 shown in Figure 1. A switch thus located gives the caller control of the, operation of the fan.

An alternative embodiment of the invention is shown in Figure 4 in which the lintel panels 10, the support channel 18, the ceiling side plates 14, the translucent panel 20 and the illuminating lamp support angle 32 and the illuminating lamps 34 are identical to those described in connection with Figure 3. In this modification of the invention, the fan motor 48 is supported by means of a frame 50 which extends upwardly from the fan grill 52. In this arrangement a switch'54 may be conveniently located in the fan grill assembly to provide for control of theoperation of the fan by a caller. Furthermore, in

this form of the invention when the translucent ceiling panel 20 is swung downwardly in the position of the panel 20 shown in Figure 3, the entire fan assembly including louver and fan blades swing downwardly with the hinged panel thus providing a still greater degree of access to the fan and fan motor than has been heretofore provided. It will be evident that the moving parts of the fan will, on occasion, require cleaning and other maintence and this extreme degree of accessibility is highly desirable. Furthermore, the lamp tubes 34 may be more easily and more completely examined when the fan motor and the blower are displaced from their position within the lamp tubes when the translucent ceiling panel is hanging downwardly.

From the foregoing it will be evident that both embodiments of the invention described herein provide a central air inlet in the ceiling of a telephone booth and surrounding illuminating means which are unobstructed while at the same time both embodiments also provide the necessary access to both the air blower and the involve the relocation of the air inlet or outlet provided -bythe louvers 36 and the air duct 37 to, for example,

the top cover'plate extending over the top of a ceiling It will be evident that these and other modific'ations may be made in the structure embodying the invention as disclosed herein without departing from the scope of'the' invention as set forth in the following claims.
