a. is an outer cylindrically shaped shell which extends, preferably in one piece, from the floor of the booth to its roof. The shell is not a complete cylinder, but has a vertically extending opening of somewhat less arcuate extent (say 90 w or less) than that of the sliding door hereinafter (ol. raaf-2) described. Secured to the inner wall of the outer shelll a, respectively above the bottom and below the top thereof, are circumferentially extending angle irons b and c. Resting on the lateral wing of angle iron b is an angle iron d. lSecured to the depending wing of angle iron d and extending above it is a circumferentially extending plate e. Hanging from the angle iron c is a circumferentially extending iron f. Resting on the lateral Wing of angle iron d and respectively at top and bottom against the outer faces 0f the depending wing of angle iron f and the upwardly projecting part of plate e, is the inner cylindrically shaped shell or lining, g, of the booth. This inner shell has substantially the same arcuate extent as the outer shell and is, preferably, also of one piece. The space between the outer and inner shells is lled with any suitable sound-insulating material h.

Resting on and extending inward beyond the lateral wing of the angle iron f is a fiat ring i. Screws a' extending through ring i and the lateral wings of angle irons f and c removably secure these members together.

Resting on the ring i is the outwardly extending annular flange of the false top, or ceiling k, of the booth. The flange of the ceiling lc may be secured to ring i by means of screws m. The ceiling is shaped to provide, adjacent its outer ange and above the ring i, a circumferentially extending channel n for a purpose hereinafter described.

The booth is provided with a flanged roof or top piece o which telescopically engages the outer shell a. Preferably a reinforcing ring p, beaded along its loweredge, is secured to the shell a, and the flange of the top o rests on the bead of the ring p.

The shell a has secured to its inner face, near its upper edge, a reinforcing ring r, and the roof o has secured to its lower face, near its depending marginal ange, a reinforcing ring s that rests on the uriner edge of the ring r when the roof is in position.

The booth is provided with a floor or base plate t, which is provided with two holes through which, from the bottom, are inserted two annullarly flanged tubular guides u. Resting on the base plate and telescopically engaging the guides u are two tubular standards v, which extend up through the interior of the shell, through holes in the ceiling k, through the compartment w formed between the ceiling lc and the roof, and into holes in the roof. o the standards v are secured a vertically extending plate .7: for supporting the telephone instrument and coin box (not shown), and a shelf y.

To the lower face of the oor t of the booth are secured spaced apart hat discs 64, which rest directly on the floor of the building in which the booth is located.

Within the compartment w is an electric light l0. An opening H in the ceiling 7c (see Fig. 7) allows the light to illuminate the interior of the booth. Properly positioned within the compartment w is a reflector l2, which throws an arc of light horizontally so as to light any sign composed of letters, figures, or trade-mark (z) which may be cut out of the surrounding flange of cover o and backed up with a transparent material so as to permit the light to penetrate through such sign.

The compartment w may also contain a fan (not shown) for delivering air through a screened inlet I3 in the roof and through one or more holes I4 in the depending flange of the ceiling 1c to the interior of the booth.

The wires for the electric light and fan motor and the telephone wires may be brought in through the hollow standards from either the holes in the floor t orthrough holes in the roof.

The electric light, and the fan also, if desired, may be controlled by a switch which is operable by the sliding door hereinafter described. This is a known arrangement and need not, therefore, be shown or particularly described.

It is necessary to afford closures between the outer and inner shell along the vertical edges thereof forming the doorway and to provide for sliding the door across one of said edges and sealing it (when closed) along both edges. The following construction ei'ects these purposes. The outer shell a, along the left hand vertical edge (see Fig. 4), is bent inward and thence backward about in alignment with the inner shell g. Applied to the inner face of the backward bend of the shell a is a block 2D of flexible material, such as felt, having a recess for the reception of the edge of the door 40. The block 20 is backed by a plate 2l, and the block and plate are held in position by means of a metal strip 22, which extends inside and along the backward bend of shell a, along the rear face of plate 2|, over the block 20,-thence bent back upon itself over the block 20 and back of the plate 2|, thence along the inner face of the inner shell g and back upon itself against said inner face, and thence around the edge of shell g and against its outer face.

At the other, or right hand, edge of the doorway the outer shell a is bent inward and thence backward and has secured to it a block 30 of felt or other suitable material, against which almost abuts the corresponding vertical edge of the inner shell g. A metal strip 3l extends within the backward bend of the outer shell, thence along the block 30 and behind it and between it and the end of shell g, thence along the inner face of the inner shell g and back upon itself against the said inner face, and thence around the edge of shell g and against its outer face.

Secured to and, projecting above the floor t of the booth are shafts affording bearings for rollers 4l between which slides the lower end of the door 40.

The :nain body of the door comprises a hollow shell filled with sound insulating material. The upper part of the door extends into the channel n formed in the ceiling k. The inner wall of the door shell extends up beyond the outer wall and has secured to its outer face a reinforcing plate 42. Turning on pins secured to the extension of the inner door shellwall andthe plate 42 are trolley wheels 43 (see Figs. 2, .5V and 6) which roll on a track 44 carried on the'upper face of ring z. l

Depending from ring i is an angle iron 45, to

the depending arm of which is secured a buier block 46, against which the upper end of the right hand edge of the door is adapted to abut when the door is fully opened. v Secured against the lower face of the ring i is a detent 41 of spring material, the under bend of which is adapted to be engaged by the upper corner of the door as it approaches its closed position and to yield upwardly and longitudinally to allow the door to be fully closed, whereupon the detent snaps into a notch 48 in the upper edge of the door and yieldingly holds it closed while again yielding to permit the door to be opened upon application of a reasonable pulling force.

When the door is closed, a flange along one vertical edge of the door extends into a recess in the felt block 20 (see Fig. 4). 49 along the other vertical edge of the door engages the inner face of the felt block 3U. Thus both vertical edges of the door are sealed.

The door 40 may also be provided with an arm 50 (see Fig. 2) carrying a roller 5l which extends between the depending wings of angle bars b and d.

The do'or 40 may conform to the radius of the booth, as shown, or it may have a flat contour. The door shell is preferably cut away to form a glass-covered opening. It is preferred to divide this opening by an upright center bar 52 and to provide this bar and also the edges of the door shell with grooves adapted to receive glass panes 53, 53.

The fioor or base plate t may be provided with a floor covering of linoleum or other material (see Fig. 2). Across the door-way, and in front of and fiush with the linoleum covering, is a metal strip 63 having a nose which is bent down in front of the front edge of the base plate t. A linoleum covering, or other material, 6I, may be applied to the inner wall of the outer shell a between the covered floor and the angle bar b. The inner wall of the outer shell may have applied thereto, adjacent the base plate t, a reinforcing plate 62, and the material 6| may be applied to this plate and to the inner wall of the outer shell.

The upper ends of the tubular standards v are preferably connected with and supported from the reinforcing ring r by means of laterally extending nipples 10, 10 connected by unions 'H (see Figs. 2 and 7): The two standards c may be connected together by means of nipples 12, 12 connected by a union 13.

When it is desired to disassemble the booth, the unions Il are removed, the screws m are removed and the top o lifted off. The screws :i are then removed, which permits the inner shell or lining f'to be lifted out. This gives access to each of the shells from both sides, thereby enabling any dents therein to be smoothed out. Since the telephone instrument, coin box and shelf are carried by the standards v, the inner shell or lining can be removed without disturbing any of these fixtures.

Except for the described buffers and floor covering, the entire booth may be constructed of metal, and since the sound deadening material is A spring plate also a nre-resisting material, the structure is fire-prooi. When the door is closed, not only does the wall prevent the transmission of sound through it, but the vertical edges of the door are sealed against the doorway and the booth is virtually sound-prooi. My experiments show, also, that a booth oi cylindrical shape eliminates low notes, While the other structural features, particularly the double wall enclosing insulating material, keep the high notes within the booth and prevent ordinary sounds from the outside penetrating thereinto. ,f

In Fig. 8 is shown a modiication wherein the shell of the booth is composed oi a single wall, 80, instead of two walls spaced apart. The outer shell is bent inward and backward upon itself at both ends to form the door frame. Secured to the shell 80, adjacent opposite ends, are holders carrying buiers 8|, 82. When the door is closed, one buffer 8| is adapted to be engaged by one vertical edge oi the door, while the other buffer 82 is adapted to be engaged by a flange on the opposite vertical edge of the door.

Fig. 9 is a diagram of the booth lof Figs. 1-7, enclosed, except for the doorway, in a rectangularly shaped box 90, so that the booth presents, exteriorly, a cubical shape.

Instead of making the booth of double walled cylindrical form, it may be made ci double walled polygonal form, as shown in Figs. 10 and 11. In Fig. 10 parts of two adjacent iiat sections |00, are cut away to form a doorway; the door l0|, when closed, spanning the space between these two thus narrowed ilat sections. In Fig. 11 one entire ilat section and also (preferably) short widths of two adjacent fiat sections |02, |02, are cut away to form the doorway; the door |03, when closed, spanning the completely eliminated shrt section. Y

In Fig. 12, the booth ||0 is made of double walled rectangular form. The door may be guided by rollers ||2, supported from the floor as shown in Figs. 13, one inside and the other outside the path of travel of the door. Instead of the door engaging stationarily positioned rollers, the door may carry one or more rollers H3, which engage a track ||4 secured to the floor of the booth, as shown in Fig. 14.

In place of the door guides shown in Figs. 2, 13 and 14, the door may be provided, along its lower edge, with a recess'l 5, as shown in Fig. l5, and withinthis recess may extend a roller ||6 supported from the floor, the roller being adapted to engage either side wall, or both side walls, of the recess. If adapted to engage both side Walls, there may be some danger of binding, for which reason it is preferred to support pairs of rollers |'l from the floor, as shown in Fig. 16,

'one roller engaging one side wall of the recess and the other roller engaging the other side wall of this recess.
