stantially rectangularly-shaped opening in its upper portion for receiving a box-like casing, with means carried by the casing for securing it at a number of points to the wall panel, this casing being filled with sound-proofing material such as rock-wool retained in position therein by a perforated plate which forms a lining for the interior of the booth, while means in the form of a Wooden frame secured to the wall panel exteriorly of the booth serves as a guard against damage to the box-like casing.

Each of the side walls for the booth consists of two panels having registering openings and securely held in contacting fiatwise relation to each other to form a mounting frame for a cas-, ing closing the rectangular opening of the exteriorly disposed wall panel with means carried by the peripherally disposed rim of the casing for securing the latter in assembled relation in the registering openings of the panels. Means in the form of perforated plates similar to that used in connection with the rear wall serve as a lining for the side walls at the interior of the booth, while moldings serve for collectively securing the longitudinal adjacent edges of the perforated plates at the corners of the booth to the rear wall and inner panels of the side walls.

The ceiling of the booth consists of supporting means in the form of a Wooden frame to which a perforated plate is secured to form a container for sound-proofing material, with means secured to the perforated plate outwardly of the booth for supporting a lighting fixture, the top edges of the inner wall panels included in the side walls providing means for supporting and securing the ceiling thus constructedin assembled relation to the walls. Means secured to the rear wall and to the outer panels of the side walls and to the front wall is provided for supporting and securing a roof of non-metallic material, while the rear wall and the side walls are held collectively in assembled relation at their lower ends by means in the form of a base having upright extending flange portions fitted between the panels forming the side walls of the booth.

Means secured to the rear wall and side walls serve as linings at the interior of the booth, such linings extending from the lower disposed edges of the perforated plates to so-called kick plates formed with a flooring of non-metallic material secured to the base. of the booth with means provided for securing the upper edges of the kick plates and the lower edges of the linings collec tively to the booth walls, other means being secured to the. rear wall and to one. of the side walls to support a telephone apparatus in the form of a coin collector in the sound-proof zone of the booth.

Other novel features and advantages of the invention will appear from the following description and by the claims appended thereto, reference being had to the accompanying drawings in which:

Referring to the drawings, a metallic base IS having formed integrally therewith at three sides upright extending flange portions such as ll, best seen in Fig. '7, one of which is secured to the outer disposed surface of a rear wall R at its lower end, while the other flange portions of this base are fitted between the cooperating panels l2 and i3 of the left side wall R2 and the right side wall R3 of the booth. The panels l3 of the right and left side walls are secured to the side flange portions H of the base by a number of screws I4 while the rear vwall R is secured to its flange portion II by a plurality of screws I5, the wall panels l2 at the right and the left side of the booth being secured along their longitudinal edges to their cooperative wall panels l3 at the rear of the booth by a plurality of wood screws l6 shown in Figs. 1, 2, 5 and 7.

- The frontwall R4 which forms the entrance of the booth is grooved longitudinally as shown in Fig. 2 for receiving tongues H and it at the longitudinal edges of the panels l3 of the right and left side walls and these walls are held securely in assembled relation at their longitudinal edges by wood screws l9 and 20. Similarly, the rear wall R of the booth is provided with longitudinally formed grooves for receiving tongues 2| and 22 formed longitudinally of the panels I3 of side walls R2 and R3 at the rear of the booth, these walls being held securely in assembled relation at their longitudinal edges by a plurality of wood screws 23 and 24.

A ceiling CL for the booth as shown in Figs. 1,

4 and 5 consists of a wood frame 25 to the underside of which is secured a perforated metal sheet.

28 retaining in place a sheet of woven fabric 29, best seen in Figs. 4 and 5, a pad 30 of fibrous material such as rock-wool for sound-proofing the top end of the booth, and a second sheet of woven fabric 3|, the perforated sheet metal 28, the rock-wool pad 35 and sheets 29 and 3| of woven fabric each having a central opening for receiving a wood frame 32 provided for mounting a fixture LF, best seen in Figs. 4, 8 and 9 for the lighting of the booth, this fixture having a metallic casing 50 provided for housing a wire connector 5| and a switch mechanism not shown for controlling the operation of a lamp 52 while an inverted translucent dome 53 and a molding ring 54 close the opening of the frame 32 at the underside of perforated sheet 28, the ceiling CL, thus constructed being fitted interiorly of the booth and supported on the top disposed edges of panels [3 of the side walls R2 and R3 where it is secured by a plurality of screws 21 best seen in Fig. 4.

The panels l3 of the side walls R2 and R3 are provided with rectangularly- shaped openings 33 and 35 registering with similarly sized rectangularly- shaped countersunk openings 35 and 36 see Figs. 4 and 5 in their cooperating panels l2 for receiving the peripheral rims 3s and 40 of two casings 31 and 38, thelatter casings cooperating with perforated metallic plates 46 and 41 to form housings for sheets of woven fabric 4| and. 42 and pads P and PI of sound-absorbing material, such as rock-wool, provided for sound-proofing these walls a distance extending from the underside surface of ceiling plate 28 down to a point substantially midway of the length of the booth as shown in Figs. 1 and 3. I

To the rims 39 and 40 of casings 31 and 38 are welded a plurality of similar angle pieces as 60 provided for securing these casings and their metallic perforated plates 46 and 41 collectively as by screws 63 to the'panels [3 of the side walls R2 and R3, as shown in Figs. 2, 5 and 6. The rear wall R of the booth as shown in Figs. 2, 4 and 5 is provided with an opening for receiving a casing 0L3 cooperating with an apertured plate 55 for housing a pad 56 of sound-proofing material and a sheet of woven fabric 51, while a wood frame 58 shown in Fig. 2 is nailed to the rear wall R to serve as a guard against damage to the sound-proofing casing GL3. The front wall R4 is provided with an opening for receiving a door consisting of folding door sections FS and PS! hinged together by a so-called piano hinge 59 while the folding section FSI is pivoted onto the front wall R4 by a pair of hinges 6| in a manner to permit the movement of the door from the folded position shown in Fig. 1 to the unfolded closed position shown in Fig. 2.
