3 Claims. 1

This. invention relates toimprovements in advertising devices, particularly those having; selfcontained electrical illuminating means.

One object of the invention is to provide an advertising display or sign for the inner face of public toilet booth doors, said display having selfcontained electrical illuminating means whichare switched on automatically by the act of latching the door closed from the interior of. the boothand are extinguished by unlatching. the door from the same side.

Another object of the. invention is to provide switching means operable; by any one. of the several types of latch utilized. on. such doors.

Still. another object of the invention is so to construct and. arrange the various elements of the invention as to allow of its application to booths already constructed and in use, in a minimum amount of time and. with very few, if any, minor alterations in the components of the booth.

Other objects and features of novelty will become apparent during the course of the following description which is to be read in the light of the annexed drawing, wherein:

Fig. 1 is a plan view of a toilet booth incorporating an advertising display in accordance with the invention.

Fig. 2 is a face view of the'inner side of the door with the walls sectioned and broken away and illustrates the advertising display and portions of the wiring for same.

Figs. 3, 4 and 5 are fragmentary views on a large scale of three different types of latches employed on toilet booth doors and illustrate the manner of cooperation of said latches with the electrical switch utilized by the invention.

Fig. 6 is the schematic wiring diagram of the invention.

Fig. 7 is a face viewof a modified advertising display.

Fig. 8 is a fragmentary detail illustrating the mounting the switches for said modified display,

and Fig. 9 is a fragmentary sectional view of a positioning device for said switches.

The toilet booth. illustrated in Figs. 1 and 2 comprises, as usual, wood or metal partitions I and I I projecting outward from a building wall I2, the former partition having a door I3 hinged to its free end and the latter partition having a face board I4 fastened to its free end and extending toward said door. The door I3 is hinged to swing into the booth when the door is opened.

The door may be. provided with any one of several types of latch, three being shown. in Figs. 3, 4 and 5.v Referring to Fig. 3, the latch shown therein comprises a bolt I slidably mounted in a housing I 6 bolted to door l3 and having a finger piece I! whereby the bolt can be slid into and withdrawn from a keeper I8, which is shown partially broken away in Fig. 3, secured to face board [-4. The latch of Fig. 4 comprises a bolt 20 pivoted on a shouldered screw 2| in door I 3. a limit stop 22 secured to the door and a keeper 23 fastened to face board M. In its unlatched position the bolt 20- rests against the limit stop 22 as shown in. dot-dash linesin Fig. 4 but can be swung about its pivot into engagement with keeper 23 by means of a knob or-finger piece 24 thereon.

The latch depicted in Fig. 5 consists of a bolt 25 projected from, and withdrawn into a housing 26 by means of a rotatable finger piece 21, and a keeper 2%], the housing 26 being mounted on the door [3 and the keeper 28 on the face board M.

The advertising display-may be of any suitable sort, the one depicted in Figs. 1 and 2 having been selected solely for purposes of illustration.

That display consists of a box 29 mounted on the inner face of door l3 and having a hinged front portion 30 which may beswung open to gain access to the interior of the box. Front portion 30 is made up of a. bevelled frame surrounding a window in which the advertising placard 3| is framed and behind which, an electric lamp 32, preferably a fluorescent tube, is mounted in the box. Such tubes, and the manner of mounting them are so well known that it is deemed necessary herein only to indicate them diagrammatically.

According to the invention the wiring for lamp 32 is so arranged as to require no changes in the structure of the booth. In the instance of the invention illustrated in the drawings the

conductors

33 and 34 for transporting current to the lamp emerge from box 29', (Figs. 1 and 2) are supported on door [3 in a strip of sheet metal channeling 35 and are carried to partition I0 in a length of flexible, armored cable 36, said cable being of a length suflicient to take into account the swinging of door [3 on its hinges. The conductors extend in channeling 35-along the top of partition [0 and across wall 12 to partition II where conductor 34 (see also Fig. 6) is connected to one terminal of a plug 31 engaged in a wall socket supplied with house current. The other terminal of plug 31 is engaged by a conductor 38 which, along with conductor 33 extends in channeling 35 along the top of partition II and onto face board M. The channeling and wires then travel down the inner side of board M to the keeper of whatever type of lock is provided. Mounted in the keeper or adjacent to it as shown in Figs, 3, 4 and 5 is an enclosed, two way make.

push button switch 40, the button of which i! resiliently extended into the path of the bolt.

It will be seen that as the bolt is advanced into the keeper to lock the door,

conductors

33 and 38 make contact and a circuit is closed (Fig. 6) from supply through conductor 34, tube 32, conductor 33, switch 40 and conductor 38 to supply return.

It will be realized of course that the particular physical arrangement of the circuit that has been described would not be satisfactory for all booths, but that the paths of the channeling strips 35 would have to be relocated to suit the conditions at hand.

In some instances, it is desired that two separate advertisements be displayed, and to this end, the box 29 is divided into two parts separated by a partition and frame at (Fig. '7) is provided with a center piece 4| to provide separate windows for two advertising placards 31. Each advertisement is illuminated independently of the other by a

fluorescent tube

32 or 32, the former being wired exactly as described above, and the latter having one of its termina s strapped as by lead 52 (Figs. 6 and 7) to lead 34 of the first tube and having the other terminal connected by lead 43 with one pole of a second push button two-way make switch M. Said switch is positioned adjacent the switch 40 described above in a manner to be described more fully hereinafter and has its second pole strapped by lead 44 to that pole of switch 4! which is connected to supply by lead 38. It will be seen that depressing the push button of switch 48' completes a circuit from supply through

leads

34 and 42, tube 32', lead 43, switch 45', lead 44 and lead 38 back to supply.

Switches 4!! and 43' may be mounted in any suitable way, but in order temporarily to disable the circuits to either or both of the fluorescent tubes 32 and 32', as for example when no advertising matter is present in either or both win dows, the switches are mounted as follows:

The switches are secured on a substantially T-shaped slide 45, the crossbar of which is provided at each end with a T-shaped slot 46 embracing the shouldered portion of a screw 41. The slots 46 are of such dimensions that when the slide is positioned vertically (Fig. 8) to locate the screws 4! at the centers thereof, the

push buttons of both switches are in the path of the bolt, which in Fig. 8 is indicated as bolt of the latch shown in Fig. 3 but which could just as well be bolt 20 (Fig. 4) or bolt 25 (Fig. 5). However, if slide 45 be moved up or down the push button of switch 40 or switch 40', respectively, is moved out of the path of the bolt and 'willnot be operated thereby; and if the slide be moved to the right in Fig. 8, so that the screws 41 are positioned in the horizontal branches of slots 46, the push buttons, although both remaining in alignment with bolt I5, are situated beyond the range of movement thereof and neither switch is operated thereby.

In order to maintain slide 45 in any of the four positions to which it may be moved, the third leg thereof is provided with a positioning device having a knurled head 48 (Figs. 8 and 9) which may begrasped by the fingers, said fingerpiece being the enlarged end of a plunger 50 which passes through a tubular casing 5| secured to slide 45 and projects through said slide mto one of four suitably positioned holes or sockets 52 in face board I 4. Within the casing the plunger is provided with a peripheral shoulder 53 with which a coil spring 54 ooacts ill llflillr.

taining the plunger in hole 52. To move slide 45, the plunger 50 is pulled free of socket 52 by means of head piece 48 and then, after repositioning said slide, allowed to snap into another hole 52 under tension of spring 54.

It is appreciated that in place of having the spring pressed two-way switches operated by the bolts of the various type latches, the switches could be mounted on the partition H) to be engaged by the pivoted edge of the door I3. In that position, the act of closing the door [3 would cause the pivoted edge of the door to engage the switch and complete the circuit to illuminate the sign carried by the inner face of the door.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

1. Means for adjustably mounting a pair of switches controlling separate electrical circuits on a face board against which the free edge of a pivotally mounted door closes so as to be selec tively independently closed or simultaneously closed by the extendable bolt of a lock mounted on the free edge of the door, comprising a slide extended vertically along the face board and having the switches mounted thereon one above the other to be engaged by the bolt when ex tended, said slide having vertically extended slots in its top and bottom ends, screws passed through said slots and threaded into the face board supporting said slide for vertical movements relative to the face board and the extend able bolt, and means for releasably holding said slide in desired vertically adjusted positions in which both switches will be engaged by the plunger when extended or in which one or the other of the switches will be engaged when the plunger is extended. 2.
