Y
vThe object of the present invention is the provision of a combined Ventilating and lightnxture unit of thevtype above-referred to which will be simple in construction and efficient in operation. In the drawing: y Fig. 1 is a view of the combined Ventilating and light iixture unit installedl'into va telephone booth, the booth being shown in perspective;
Fig. 2 is a top view of Fig. .l shown with vthe roof removed from the telephone booth and an air exhaust conduit of the Ventilating assembly shown with portions vbroken away;
Fig. 3 is `a frontview of the Ventilating and light xture unit, the ceiling and roof for the booth and the air exhaust conduit being shown in section taken on line S-Bof Fig.,2;
Fig. 4 is a partial view ofthe telephone booth shown in vertical section, diierent conduits of the Ventilating and light nxture unit being shown with portionsbroken away;" v .l
Fig. 5 is a front View of the Ventilating assembly shown with the front plate removed andwith portionsV or" 'different air conduits with portions broken away; and
Fig. 6 is a horizontal sectional view taken on line 6 5 of Fig. 4.
In accordance with the construction of the Ventilating and lighting xture unit of this invention, a sheet metal plate is bent laterally at right angles to form the walls IG and my of a casing tted at a corner of the telephone booth B, as best seen in Figs. 1 and 6, while a diagonally disposed plate II forms the front wall of the casing. A bottom wall I2 is secured to the walls I and Illy at their lower ends by a molding strip I4 and a plurality of screws I3. The front plate I I is secured to the parallelly disposed edges of walls Iii and |91/ by similar molding strips Illy and screws I5, while the top end portion of plate I I is secured to a molding strip I6 best seen in Figs. l, 3 and 4 by a plurality of screws Il, the strip I6 in turn being secured to the ceiling I8 of the booth by a plurality of screws Il.
The walls II! and Iy of the casing are Iformed with lug members I9 and 2e best seen in Figs. Li, and 6 serving for securingan air conduit 2| yconnecting with an air conduit 22 and an air blower 23. The air conduit 2| extends downwardly and terminates in the form of an elbow curve leading the stream of air generated by the blower 23 toward the person using the telephone booth. v
A valve 24 in airconduit 2lV is adjustatblev by the rotation of a rod 25 having a knob 26 which may .be actuated by the occupant of the'fbooth for.r controlling the stream of air delivered Vthr'ougha grid 2l atV the terminating endEof the .elbowf portion .of conduit 2i. Conduit 2 2Las best lseen infFig's. 2, 3, 4,5 and 'terminates' inl'the form of'a nozzle 28, disposed in concentric relationv tol'an, l enlarged'. portion of .an air'jconduit 29`of rectangular cross-section forming an' air exhaust path from two louver plates 32 and 33 at the int'eriorof thebooth to a louver plate 30 secured tothe .exterior of the booth, whileA another" louver .plate 3| secured to the top` front wall-,of the biooth forms an air conduit extending through 'the' space between the ceilingv I8 and roof ,Iyof the boothto the intake of blower2v3.
A` plate 34 as bestl seen. in Fig.VV 4v is secured tothe rear side lof front lplate I I and to' the bottom wall` I2V as' by screwsand 36tojsfervefor reenforcing'jthe casing thus y j constructed "and jas a reflectorjjfor falamplfprovided jfor lighting the telephone.' apparatus as' for example' a. coin kcollector 38 through Va 'j translucent glass plate "40' and the interior of the booththlough a trans'.-
lucent glass plate 40g, the energization 'of 'the lamp 31 and of the motor forl the air blower 23 being effected by the operation of a common switching device not shown controlled by the closing and opening movements of the folding door lil at the entrance of the booth.
In the operation of the Ventilating iixture of this invention, the closure of the telephone booth door is effective to operate a switching device for energizing the motor of the air blower 23 and the lamp 3l. The stream of air generated by the operation of the blower is directed into the booth by the air conduit 2I and through the grid 21 toward the subscriber using the booth. The stream of air from blower 23 divides at the junction of air conduits 2| and 22, the latter leading the stream of air towards the nozzle 28 disposed as above-described into the air conduit 29 to exhaust the air from the booth as by a Venturi action in a path including the louvers 32 and 33, the conduit 29 and the louver plate 30 at the top end of the booth, while the air intake path to the blower 23 includes the louver plate 3l, the space between the ceiling I3 and the roof Iy of the booth and the open top end portion of the casing. The stream of airfrom blower 23 to thegrid 2l is controlled by the adjustment of air valve 2li which may be moved in position to obtain a maximum amount of air flowing through the grid 2l or moved to the closed `position for completely stopping the flow of air through this grid. However, upon the closure of valve 24, the air stream generated by the blower 23 is now iiowing entirely into the air conduit 22 to the nozzle 28 to increase the Venturi effect and thereby accelerating the iiovvY of air from the interior of the booth to the airexhaustlouver plate 3U at the top 'of the telephone booth.
What is claimed is:
1. A Ventilating xture for a telephone booth and the like comprising a casing having an air inlet in one wall thereof, an air blower mounted in said casing, said casing having an opening in the upper portion thereof for supplying air to said blower, a bifurcated air discharge outlet duct, having two branches, connected to said blower, Ameans dening a, chamber mounted on the interior of said casing, said chamber having its lower portion communicating with said air inlet, .the -upper portion of said chamber extending beyond the confines of said casing and serving as Aan exhaust outlet, one branch of the air discharge outlet duct positioned within said chamber above said air inlet and having a length substantially shorter than the extending portion of said chamber and the other branch of said air discharge outlet duct passing through saidcasing and communicating with the interior of the Ybooth at a point remote from said exhaust'outoutlet duct, having two branches, connected to said. blower, means defining a chamber mounted on the,n interior of said casing, said chamber having its lower portion communicating with said air inlets, the upper portion of said chamber extending beyond the confinesA of said casing and` serving as an exhaust outlet, one branch of the air discharge outlet duct provided with a constricted end portion positioned within said chainber above said air inlets and having a, length substantially shorter than the extending portion of said chamber and the other branch of said air discharge outlet duct passing through said casing and communicating with the'interior of the booth at a point remote from said exhaust outlet.
3. A Ventilating fixture for a telephone booth and the like comprising a casing having a substantially triangular cross section to facilitate corner mounting, said casing having a plurality of air inlets in one Wall thereof, an air blower mounted in said casing, said casing having an opening in the upper portion thereof for supplying air to said blower, a bifureated air discharge outlet duct, having two branches, connected to said blower, means dening a chamber mounted on the interior of said casing, said chamber having its lower-'portion communicating with said air inlets, theupper portionV of said chamber exrtending beyond the confines of said casing and serving as an exhaust outlet, one branch of the air discharge outlet duct positioned within said ehamberabove said air inlets and having ka length substantially shorter than saidvextendingportion of said chamber and the other branch of said air discharge outlet duct passing through the bottom portion of said casing and extending at right angles thereto and communicating with the interior of the booth. y
