a corporation of New York; said Meehan assigner to American Telephone and Telegraph Company, a corporation of New York Application December s, 1942, serial No. 467350 1 Claim.

This invention relates to booths and more specifically to a base for use in telephone booths and the like. A

The object of this invention is the provision of a base of the type above referred to which will 5 be simple, sturdy in construction, cheap to manufacture and in which with the exception of screws and other securing parts, the use of metallic material is avoided.

According to the booth base of this invention, a floor representing, for example, a rectangular geometric-shaped figure is constructed of plywood to which are integrated by screws and gluing, wooden sleeper members in turn integrated to each other at their adjacent ends at the rear corners of the booth by gluing. The inner disposed surfaces of the sleeper members are inclined relative to the plane of the floor to provide backing surfaces for covering plates of fibrous material extending vfrom the floor to a small distance beyond complemental supporting means coextensive of the sleeper members where these plates are secured at their top edges to the walls of the booth, while angle bars are provided for securing the adjacent ends of these plates to the complemental supporting means and to the sleeper members.

Means formed with the'sleeper members reg-` istering with means formed' with the walls of the o booth serves as bearing points for these walls, "0 while means is provided at the front disposed end of two of the sleeper members for securing wall elements at the entrance of the booth. A plurality of means disposed on the under-side of the plywood floor at the rear corners, the middle and front end portion thereof, form Abearing points on which the booth assembly rests, Means in the form of a tread bar secured to the top surface of the floor is provided with means for securely holding the front edge of a covering to 40 p the plywood iioor of the booth and means in the form of moldings secured by screws to the sleeper members is provided for collectively securing the other peripheral edges of the covering to the floor and the lower disposed ends of the covering plates to the inclined surfaces of the sleeper members, while means fitted in openings in the plywood iloor serves for securing the tread bar to the front disposed edge of this iioor and to serve as bearing points for the front wall elements of the booth.

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

Y Fig. l is a top View of the base shown with the floor covering `and molding used for `securing the -covering to the oor and the covering plates to the sleeper members;

Fig. 2 is an assembly viewkshown in perspective;

Fig. 3 is a sectional view taken on line 3-3 of Fig. l enlarged;

Fig. 4 is a sectional view taken on line 4 4 of Fig. l; and

Fig. 5 is a view similar tothat of Fig. 4 showing a modification `of the tread bar shown in that ligure.

The telephone booth base of this invention comprises a rectangularly shaped plywood floor consisting of plies Yl, Y2, YB, Yli and YE best seen in Figs. 3, 4 and 5 o-n which sleeper members sml, smZ and sm3 Aare mounted. rIghese sleeper members are as shown in Figs. 2 and 3 of a relatively large cross-section so as to provide a large base surface area for integration of these members to the plywood floor to one side thereof by similar screws SC shown in Fig. 3 and gluing, while the sleeper members are integrated to each other at their adjacent ends at the left and right corners of the booth by gluing. The sleeper members sml, sm2 and sm3 are each provided with similar shoulder portions :I: and :nl `as shown in Figs. l, 2 and 3 registering with similarly shaped portions formed at the lower ends of the side walls sw and swl and the lower end of the rear wall rw of the booth shown schematically by the dotted lines in Figs. 1, 2 and 3 to serve as bearing points for these walls, while a plurality of screws (not shown) engaging drilled holes h, hl, h2 and h3 secure the booth walls to the sleeper members.

The plywood iioor consisting of plies YI, Y2,

' etc. extends at the entrance of the booth a small distance beyond the ends of the right and left disposed sleeper members sml and sm3 to serve for mounting a wooden tread bar B of. substantially rectangular cross section shown in Figs. 1, 2 and 4 which in turn serve as bearing points for the wall elements w, wl shown schematically in Figs. 1 and 2 forming the entrance of the booth, while drilled holes as dl and dfi are engaged by screws (not shown) serving to secure the lower ends of the front wall elements w and wl to the sleeper members sml and sm3, the tread bar being secured to the plywood floor by a plurality of screws inl shown in Figs. l, 2, 4 and 5 eX- tending through openings in the tread bar in engaged relation with T-nuts tn fitted in openings in a wooden strip el extending across -Athe booth and integrated to ply Y5 of the floor, while serving in cooperation with wooden spacer members z2, z3 at the rear corners of the booth and the spacer member e4 at the center of the floor to form bearing surfaces for the booth assembly.

On the top surface of the plywood floor is mounted a covering C which may be of linoleum or other fibrous material held securely thereon at the front side of the booth by a chamfered portion BI of the tread bar B as shown in Fig. 4 and along its rear and side disposed edges by similar wooden molding strips ST, while other pieces of molding STI, ST2 are provided for securing the adjacent ends of covering CPI, CP2 and C133 to the inclined surfaces of sleeper members sml, sm2 and sm3 and to the wooden strips :r1/I, xy2 and `13g/3 complemental to sleeper members smI, sm2 and sm3 respectively. These plates which are of linoleum or other similar fibrous material are held at their top disposed edges by similar molding strips MI, M2 and M3 and screws cw directly engaging the rear Wall and the side Walls of the booth, while the lower disposed edges of plate covering CPI, CP2 and CP3 are held securely against the inclined surfaces of the sleeper members by the wooden molding strips ST securing the covering C to the plywood licor as 'above described.

In this construction the cross-sectional form of the sleeper members affords a large base surface area for integrating these members to the plywood floor and thereby obtaining maximum rigidity of the base and booth assembly, while the inclined surfaces of the sleeper members serve as backing elements for the linoleum covering plates CPI, CP2 and CP3 converging to the normal inner surfaces or inner peripheries of the walls SW, SWI and RW at which points the covering plates are secured to the booth walls by the molding strips MI, M2 and M3 and screws CW as described.

In the modication shown in Fig. 5, the front end of Hoor layer yI on which the linoleum oor covering C rests extends substantially in vertical alignment relative to the edge of the chamfered portion BI of the tread bar B While the layers y2, 113 and g4 extend beyond the front edge of layer yl Vto provide a support for the at portion of tread bar B, while the layer 'g5 and the spacer member al serve to form a bearing surface for the edge of the tread bar which is curvedalong the region of the booth door to facilitate the entrance to the booth.

Booth bases constructed according to the novel features of the invention provide a comparatively low step-up at the entrance of the booth, have been found to be cheap to manufacture, of sturdy construction, free from repairs and capable of long life in actual use while using a minimum amount of metallic material.

It is understood that minor changes may be made to the booth base of this invention without departing from the scope of the appended claim.

What is claimed is:

A base for a telephone booth comprising a oor of non-metallic material, sleeper members of non-metallic material, each of said sleeper members having a base portion integrated with said floor and having a plurality of bearing portions for supporting a wall of the booth, and each sleeper member having an interiorly disposed backing surface inclined relative to the plane of said floor, and a complemental wooden strip resting on one of said bearing portions of each sleeper member and having a surface registering with a surface of one of said walls and another surface registering with the inclined backing surface of one of said sleeper members for supporting an upwardly extending fibrous covering.
