TELEPHONE BOOTH DOOR STRUCTURE Filed Jan. 13, 1937 3 Sheets-Sheet 3 v I I Q x \If V I VAVIIIIIIIIJIIII Patented July 16, 1940 UNITED STATES FATENT OFFlCE 2,208,166 V TELEPHONE BOOTH DOOR STRUCTURE Percival H. Sl1erron, Jamaica, .N. Y. Application January 13, 1937, Serial No. 120,324 3 Claims. (c1. 20- 20) This invention relates to an improved form of telephone booth door structure.
It has heretofore been customary to provide telephone booths with folding leaf doors in which the leaves were of unequal width. This was considered necessary because of the friction developed in the door pin and door hinge.
In accordance with this invention there is provided a telephone booth door structure which makes possible the use of even width leaves in the door with consequent greater ease of fabrication and assembly and improved appearance. Many other advantages in appearance, ease of operation and cost and ease of fabrication are possessed by the improved door assembly in accordance with this invention.
These advantages and the details of construction by means of which they are obtained may best be described in connection with the accompanying drawings, which show preferred embodiments of my invention.
In the drawings:
Fig. l is a perspective view of a telephone booth in which the invention is embodied.
Fig. 2 is a detail view, partly in section, showing one form of hinge construction in accordance with my invention.
Fig. 3 is a detail view of a modified form of hinge construction. v
Fig. 4 is a perspective View, partly in section, shown, partly disassembled, the several structural elements of which my improved door is formed.
Fig. 5 is a vertical sectional partial view through a booth showing the door assembly.
Fig. 6 is a detail view showing the guiding means for the door, and
Fig. '7 is a detail view of a door hinge showing an electric switch connected thereto.
A telephone booth I, which may be of any conventional design, but which preferably will be of the type disclosed and claimed in my Patent No. 2,176,980, dated October 24, 1939, has front wall portions 3 forming door jambs to one of which is secured by means of hinges 5 the folding leaf door 1. This door, as shown in Fig. 1, has two leaves 9 of even width hinged together at H and carrying glass panels l3. Adjacent the hinge on the inner side of the door is a handle |4.
Each leaf 9, is shown in Fig. 4, is formed by securing together, preferably by welding, a plurality of preformed, double-walled hollow metal sections. The central portions of each leaf 9 consists of rectangular sections l5, I], which are formed by bending flanges H3 at right angles around the edges of two panels of sheet metal,
of suitable dimensions, telescoping the panelsand welding th flanges together at I 9. The hollow column members 2|, forming the outer edge' of each lead, are made. in the same manner by telescoping two pieces of sheet metal of channel 5 cross section and welding together the contacting flanges 23 at 25. Top and bottom plates 26 are then welded in place to close the open ends. Y
The column members 21, 21a, forming the inner or adjoining edge of each leaf, are formed by blanking out a single piece of sheet metal of suitable dimensions, forming right angle flanges 29 along the long edges of the blank, bending the blank centrally about its longer axis over a 1.) form, so as to form integral hinge pole sections 3|, Sla and inset sections 33, until the flanges 29 are superimposed, and welding the flanges together at 35. Simple cover pieces 3! and cover pieces '39 carrying a bushing 4| are ultimately go welded in place at the top and bottom of the column members to close them.
The various body sections are then assembled in the position shown in Fig. 4 and united by welding the contacting portions. A window frame 43 is secured in place bounding the open ing between. sections l5 and I1, and 23 and 21;
If desired, the hollow spaces in the door assem bly, particularly within sections I5 and I1, may be filled with a sound proofing material.
In Fig. 3 there is shown a modified form of door structure, in which the column members 21' at the adjoining edges of the leaves are formed without an integral hinge pole, and sections of cylindrical tubing 45 and bushing lugs lll'are r welded to the face 49 of the columns to provide the hinge elements.
As shown in Fig. 4, the hinge pole sections 3|, 3|a are offset on the adjoining edges of the leaves 9 of the door. In hinging the two leaves of the door, a phosphor bronze or other suitable pin bearing 5| is positioned in the upper end of hinge pole 3|, in which it is a force fit, and in the lower end of hinge pole 3|a. The pin members am of these bearings are received in bushings 4! carried on plates 39 ultimately secured at the top of column 210. and bottom of column 27. A similar bearing is forced in place in the lower end of hinge pole 3|, while a bushing 52 is placed in the upper end of hinge pole 3|a in which it is a force fit. These several bearings and bushings will, of course, be secured in place and the pins 5|a positioned in bushings 4| before the plates 39 are welded in place.
In Fig. 2 there is shown a modified form of 55 9 adjacent its'free edge is a bracket memberE'I (see Figs. 5 andfi). A pin 59 rises from bracket 51 above the level of the upper edge of the door. and carries two flanges or collar members 6 I, one adjacent its upper end, the other near its lower end. Secured between the collars 6l-,.but. free to rotate are a plurality of rollers 63. Secured on brackets 65 or by other suitable means fixed to the booth walls and extending across the front of the booth just above -the level of the upper edge of the door isa track 67, the direction of ;which is that. of the motion of pin 59 as thedoorl moves from open to closed position.
The track 611 min. the, form of an inverted channel section; and the flanges 69 thereof are spaced justsufficiently to receive the assembly of rollers 63-. Gonsequently as the door is-opened or closed the. roller assembly travels along. the track. El,
the rollers 63 rotating freely and so minimizing friction: l
- Secured to one of. the hinge elements of one of thexhinges 5. so as to be. rotatable by the opening and closing of door I is astud. 'H'. Connectedvjto said; stud H by means of flexible coupling 13 and collar 15: so as to be rotatable therewith is a. cylinder: switch element 11 which is secured to a: wall of the booth above the door level by means (not shown) which will permit its free rotation. The: body of cylinder 11. is made of fibre or: other non-conducting material, but an insert 19. of. metal" or other" electrical conducting material extends over its; outer surface throughout:..anarc of perhaps b5. Mounted on the wall of? the booth adjacent theelement 11 are a pair of spring: contact: arms 81: which-are interposed inx one side of the electric circuit leading to the light, fan, etc. with. which. the booth may be provided. i
With the booth door I in open position the contact arms 8| will rest on the non-conducting surface of the cylinder ll, the circuit will be broken and the lights and fan will not operate. When, however, the booth door is closed, as it will be when the booth is in use, the cylinder 11 will have been rotated by means of hinge 5 and connector 13 so that the contact arms 8| rest on the metal insert 19, as shown in Fig. '7, thus completing the. circuit to the lights and fan.
What I claim and desire to protect by Letters Patent is:
l. A telephone booth door having two leaves hinged to each other, each leaf having an outer column and a hinge column, the outer columns being formed of two telescopic channel members, the flanges of the channels being welded to each other to form double thickness edge walls,
the hinge columns being formed of a single sheet bent to form hinge pole sections, the endsof the sheet being bent to: form overlapping flanges.
the full thickness of the column, said flanges being welded to each other to form double thickmess-walls, and upper-and lower cross rails welded to the inner faces of. the columns of each. leaf.
2. A telephone booth door having two leaves hinged to each. other, each leaf having an outer column and, a hinge column, the outer columns being formed of two telescopic channel members,
the flanges of the channels being welded to each other to form double thickness edge walls, the
hinge columns being formed of a single sheet bent to formhinge' pole sections, each of which extends approximately half the length of said hinge columns incomplementary relationship to the other, the ends of said single sheet being bent to form overlapping flanges the full thickness of the column, saidflanges being welded to each other toiormdouble thickness walls, and
upper and lower crossrai-ls welded: to the inner faces of the columns of each-leaf.
3. A'telephone booth door as described in claim 2, additionally characterized by the fact that the hinge pole sections are engaged with each other by an anti-friction bearing assembly.
