Welded or otherwise secured to the inner surface of front flange 67 is an outwardly extending flange 68 of an angle member 69, having a flange 70 parallel to and spaced from flange 66, and forming therewith a slot or groove 71. The groove 71 in corner post is adapted to receive edge d of panel 25, while the corresponding groove 71 in corner post 21 is adapted to receive edge portion 26d of panel 26. As clearly shown in Fig. 2,flanges 67 extend inwardly beyond angle member 69 and 72. Ane'longated channel shaped member 73 is fixed within the corner formed by flange 7-0 and extension 72 of flange 67. Said channel 73 comprises wall 74 preferably weldedto flange 70, a wall 75 spaced from and parallel to said wall 74, and a'wall 76 interconnecting said walls 74, 75. Secured to wall 75 of the channel in corner post 20, is an elongated strip 76a welded to the inner portion of said wall, for a purpose hereinafter appearmg.

It will be noted that the corner posts 18',

the- panels 25, 26 and 27 are somewhat longer than said corner posts. In building up the booth 10, the corner posts are first assembled with panels 25, 26 and 27 by inserting the side edge portions of said panels in their respective grooves in the corner posts. 4 The tight frictional fit is sufficient to clamp these parts together. The top and bottom edge portions of said panels, however, project above and below the ends of said corner posts. The floor and roof members 11 and 12 may then be fitted to the thus far assembled.structure by inserting the lower and upper projecting edges of the panels 25, 26 and 27 in their respective grooves in frames 16 and 17. The ends of the corner posts are adapted tov abut the adjacent edges of the frames 16 and 17 thus providing a rigid, compact structure.

Swingably mounted on wall 75 of channel I 73 in corner post-21 as on hinges 115, is a door 116 comprising two sections 117,118 having windows 117a, 118a. Said sections 117, 118 are hinged together as at 119, to permit section 117 to swing inwardly into the booth while section 118 swings against said section 117 into the position shown in dotted lines in Fig. 2 A handle 120 secured to seetion 118 is provided for moving the door from within the. booth. For guiding the hinged door section 117 118 to open and closed position, a channel shaped member 121 is secured to the undersurface of board 88 in a position inclined to the front of the booth.

Secured to section 118 adjacent the upper edge thereof is a bracket 122 on which is rotatably mounted a roller 123 projecting into-the groove 124 of said channel 121. Duringopening and closing of the door 116, roller 123 is guided in said groove 1:24 by side walls 125 of said channel. In closed position, the outer edge portion 118?) of section 118 contacts stri p 7611 of corner post 20.

flanges 141, is adapted to be engaged portions 131 of lower brackets 130. A pair The door 116, at the lower end thereof,

preferably terminates short of the plate 81 and at its upper end short of channel memher 105 to provide air Ventilating spaces.

For supporting the telephone support and table 116a within the booth, adjacent corner post 19, a pair of similar Z-shaped brackets 130 are secured adjacent each other on the inner facesof flanges 58 and 60 of angle member 59 in corner post 19. Saidbrackets are secured at about the mid-portion of said angle member, and each is provided with upstanding hook portions 131. Spaced from said brackets 130 are two similarbrackets 132, likewise securedto flanges 58, and 60 of said angle members, and similarly provided with upstanding hook portions 133. The supporting frame 134 shown in Fig. 5 for mounting a table'145'is provided with means for engaging said brackets 130, 132. Said frame 134 comprises a member 135 having arms 136, and137 extending at right angles 19 and 21 are all of equal'lengths and that are adapted to be engaged by hook portions.

133 of upper brackets 132'for mounting said frame. An angle iron 140 having vertical of connecting brace bars 143 are secured at their opposite ends to flanges 141 and flanges 139 respectively, thus forming a unitary frame which may be easily and quickly mounted or removed from brackets 130, 132. Secured to the horizontal flange 138 of frame 134 is a'substantially triangular shaped platform or table 145 made of wood or any other suitable materiahwhich serves as a telephone support or elbow rest, or other like purpose. Said table is. grooved as at 146 to receive one made of sound proof material.

-It will now be understood that the integral 1 parts above described may be easily put together and assembled solely by r clamping fits and that .no bolts or screws are necessary. When the floor, roof and side walls have been assembled, the table and telephone support are simply hung in place on the bracket 130, 132andthe door secured in i place by hinging it to corner post 21. The floor, roof, corner posts, wall panels, door and in hook iction .110 I end of a vertical board 147' which cuts the telephone support may be stored and shipped in knocked down condition, and the entire assembling operation may be done at the place of installation of the booth.

It will be further understood that where parts are above described as welded together, any other suitable rigid attachment means may be substituted.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
