4 Claims.

This invention relates to telephone booths and its object is to simplify and improve the construction of such booths.

A feature of the invention is the provision of a 5: plurality of independent securing means whereby the walls of the booth are held in assembled relation at their lower ends without the use of a base.

Another feature is the provision of a novel 16" guiding mechanism for the booth door which efiected simultaneously and in timed relation with simplifies the construction of the booth while permitting a freer movement of the door.

Another feature is the provision of a lighting fixture and means whereby the use of separate housings for the switching device and the lamp socket is avoided.-

Another feature is the provision of means whereby the operation of the lamp and the fan is 2'0 respect to'the movement of the booth door.

Another feature is the provision of a ventilating system whereby the ventilation of the booth is efiected in an efficient manner and wherein the noise generated by the operation of the fan is 25 reduced to a minimum level.

Other novel features of the invention and advantages will appear from the following description'an'dby the claims appended thereto, referenoe being had to the accompanying drawings in which? i Fig. 1 is a front elevation view of the booth shown in perspective and 'with portions of one of the side walls cut away; Fig. 2 is atop view showing the roof and louver plates with portions cut away;

Fig.'13 is an enlarged view of a springused for mounting the fan on its supporting frame.

As shown in the drawings the telephone booth of this invention consists of walls Wl, W2, W3 and W4 which are held in angular relation at their lower frontend by two angle-shaped metallic members 28 and El and at their lower rear end by triangularly shaped

metallic members

22 and 23 secured to the booth walls by a plurality of ordinary wood screws 24, shown in Fig. 1, members and 2! being'in turn welded perpendicularly or formed integrally with a cross-brace 25 which serves to maintain the portions PI and P2 of front wallWl in space relation atthis point.

The walls WI, W2, W3 and W4 are held in angular relation at their upper ends by a ceiling 26 resting on the top ends-off wall's W2' and W4 as shown in Figs; 2 and 3 'and is secured thereto by a number of wood screws 21. On the top ends of walls W2 and W4 above the ceiling 26 is mounted a roof 23 provided with two oppositely disposed

openings

29 and 30 which are fitted with louver plates 3! and 32, the roof being held securely by a number of wood screws 21' A vertically disposed partition 33 extends from ceiling 26 to roof 28 to form two compartments 0 and CI for housing a fan assembly unit FA consisting of an ordinary'motor M and a fan wheel FW and a lighting fixture LF including a controlling switch CS, shown in Figs. 2 and 3.

The front wall WI is provided with an opening OP fitted with a door formed of two folding sections FI and F2. The folding section Fl is pivoted to one side of wall WI by a number of hinges, such as H3, shown in Figs. 3 and 4. The pin of the top hinge H3, however, is secured to the movable hinge flap'48 by screws 41 and rotates therewith upon the folding movement of the door. This hinge pin is formed integrally with a rod portion 45 extending above the ceiling 26 in a bearing in the form of bracket 55 for mounting a lever member 44, this bracket being secured to the front wall of the booth by screws 56 and 51.

The lighting fixture LF consists of plates 34 and 35 held to the ceiling 26 by a number of clamps, such as 36 and 31 shown in Fig. 3, and the lower disposed plate 34 is provided with a plurality of angularly disposed air openings dl shown in Fig. 1 and its central portion is fitted with a translucent dome-shaped glass shade 38. On the top surface of ceiling 26 is securely mounted a bracket 39 fitted with a casing 40 having a cover 40' provided for housing the terminals of the lamp socket 4i and a controlling switch US which may be of any well-known construction having an operating arm such as 43 for connection with the arm 44 at the end of rod 45, such connection being effected by a lengthwise adjustable bar 49 extending through an opening in the wall of casing as shown in Figs. 2, 3, 11 and 12.

The ceiling 26 is provided at its rear right corner with a square opening fitted with a similarly shaped frame 6| held securely thereon by a num-v ber of screws 62. This frame is provided at its corner portions with inwardly extending lugs such as 63 and 64 provided for hooking similar ends of a plurality of spring members, such as 65, the other ends of these members being disposed tangentially and hooked to corresponding

lugs

66 and 61 carried by the motor housing 68, on the armature shaft of which is mounted the fan wheel FW for rotation in the opening 60 of ceiling 26. r

The door section F2 is provided at its upper portion with a bracket 10 held securely thereon by a number of screws 12 and on the pivot of this bracket is mounted a slider member H which cooperates with a guide formed by two parallelly disposed rails 13 and M for controlling the movement of the door from its folded position as shown in Fig. 1 to its unfolded position as shown in Figs. 2, 3, 4 and 6. The rails 14 and 13 are secured to the front Wall of the booth by the sets of screws 16 and H engaging spacer members 18 and 19 at each end of the rails, the ceiling being provided along the rails with an open slot 80 shown in Figs. 2, 3, 4, 5 and 6 connecting the interior of the booth to the compartment Cl at the top of the booth in order to assist in the exhaust of the air from the booth as will be hereinafter described in detail.

The motor M of the fan is connected to the current supply line 8| through the controlling switch CS, the cable 82 and the wires 8 and 85, and a manually operable switch 86 shown in Fig. 1 is provided adjacent the telephone apparatus TA in the booth for independently and manually controlling the operation of the fan, the telephone apparatus being preferably positioned directly in the current of air generated by the fan.

In the use of the booth of this invention upon a predetermined movement of the booth door from its folded open position shown in Fig. 1 to its unfolded closed position shown in Figs. 2, 3 and 4 as controlled by the movement of slider ll between the guiding rails 13 and I4 is effective to impart movement to the switch arm 43 through its connection with the bar 49 for causing the operation of the lamp 42 and simultaneously the operation of the motor fan M.

The operation of fan wheel FW is effective to generate a current of air passing through an air inlet path including the louver plate 3|, the openings in the frame FA and the fan wheel opening 60 in the ceiling 26, the air current being directed in the interior of the booth toward the general location of the telephone apparatus.

The air is exhausted from the interior of the booth partly through the openings in'the lighting fixture plates 34 and 35 and partly through the slot 80 in the ceiling 26 from which it is finally exhausted through the louver plate 32 separated to the greatest distance to that of louver plate 3! as to prevent any amount of exhausted air to reenter the booth through this latter path, while the incoming air is prevented from mixing with the exhaust air in the space between the ceiling 26 and the roof 28 by the partition 33.

In this booth the disposition of the air inlet and exhaust paths at the top of the booth provides an efficient ventilating system and the use of springs 65 tangentially connected to the motor M effectively neutralizes the vibrations generated by the operation of the motor and thereby reduces the noise in the booth to a minimum level, while the lamp and switch unit together with the use of angle shaped members for securing the walls of the booth at their lower ends improves the construction of the booth and effects considerable saving in cost.

Obviously, minor changes may be made in this invention without departing from the scope of the appended claims.
