R. w. BERGMAN SANITIZING DEvIcE Filed may 21. 1942 -Mwwf Patented May 30, 1944 A SANITIZING DEVICE Raymond W. Bergman, Lockport, IIL, assigner to The Scholl Mfg. Co., Inc., Chicago, lll., a corporation of New York Application May 21,1942, serial No. asse s claims. (ci. 21-54) This invention relates to improvements in a sanitizing device and a method of sanitizing, the invention being highly desirable for use in connection with the sanitizing or sterilizing of articles of wearing apparel such, for example, as shoes, gloves, hats, etc.

Frequently, in stores or other places where articles of clothing are sold or otherwise dispensed, it is necessary for a customer to actually try on the particular article desired before a proper fit is obtained. This is especially true in stores where shoes are sold. Ofttimes a customer will try on several pair before deciding which pair to purchase, and if that customer is a victim of some infectious ailment or disease, the shoes tried on but not purchased are quite probably infected. Thus, there is the danger of a subsequent customer acquiring, innocentlyy enough, some such aiiliction as epidermophytosis, pompholyx, scabies,

, or some other serious or distinctly uncomfortable aiiction. 'I'he lsale of gloves, hats, and similar items of apparel may also result in the transmission of infectious skin diseases and eruptions.

With the foregoing in mind, it is an important object of the present invention to provide a device which will easily and quickly sanitize or sterilize an article of apparel.

Another object of this invention is the provision of a device wherein the sanitizing or sterilizing medium may be disposed within the article to be treated, so as to insure adequate sanitization or sterilization.

Still another object of this invention is the provision of a device which utilizes a radiation lamp so arranged as to project inside the article to be treated to insure an adequate emanation-of sterif lizing rays to the article.

It is also a feature of this invention to provide a sanitizing device in which a sterilizing lamp is used, and which device is provided with means to both support the article of apparel to be treated and also act as a guard for the sterilizing lamp.

Still another feature of the invention resides in the provision of a sanitizing device for articles of apparel which is in the form of a cabinet with an electrical sterilizing device in the cabinet, and in which cabinet the article to be treated may be placed, the energization of the electrical sterilizing device being controlled automatically by the door of the cabinet.

While some of the more salient features, characteristics and advantages of the instant invention have been above pointed out, others will betaken in conJunction with the accompanyin drawing, in which:

Figure 1 is a view in projection of a sanitizing device embodying features of the present invention, illustrating its use with an article of apparel; l

Figure 2 is an enlarged vertical sectional view through the device of Figure 1;

Figure 3 is a fragmentary sectional view, with parts in elevation, of the upper right-hand portion of Figure 2, illustrating the cabinet door in partially open position to denote how the sterilizing medium may be controlled automatically by the action of the door;

Figure 4 is a simplified wiring diagram of the elecrical connections associated with the. invention.

As shown on the drawing:

For the purpose of clarity and convenience, the instant invention will be described in connection with the sanitizing or sterilizlng of shoes, an article of apparel forwhich the invention is highly desirable.

The illustrated embodiment 4of the invention includes a cabinet 5, preferably provided with a transparent panel 6 in a wall thereof. To ailord ready access to the interior of the cabinet 5, a door or lid 'I may be provided, hinged or otherwise secured to the body of the cabinet as indicated at 8, this door preferably seating in a mortised seat as indicated at 8.

One wall Il, in the illustrated instance the bottom of the cabinet, is false with the true wall or bottom' II disposed therebelow thus providing a space I2 therebetween. Secured to the true wall or bottom I I and occupying the space I2 is a pair of sockets I3 for the reception of a radiation lamp preferably energized by electricity and preferably of a character to provide ultra-violet radiation oi.' a character to destroy germs, bacteria, mold, and other micro-organisms.

Above each socket I3 the false wall or bottom III is provided with an opening I5 through which the lamp extends into the interiorof the cabinet 5. It will be noted that the lamp is thus spaced away from all walls of the cabinet except that through which it extends. Immediately below the opening I5 in the false wall or bottom III aI rays emanated by the lamp Il, extends throughv the opening I! and is secured to the flange I5.

come apparent from the following disclosures, In the illustrated instance. this guard is in the y ly simple and very highly effective.

form of a wire shield made up of a plurality of pieces of bent wire, each leg of the shi ld extending through the opening I and being turned over as indicated at I8 to provide a foot which is spot-welded or otherwise secured to the flange I6. The lamp I4 extends inside of the guard Il as clearly seen in Figure 2.

' All electrical apparatus that might be deemed necessary, such as transformers, and all electricalwiring, with the exception of a pair of leads I9 and 20 and a switch 2I located near the top of the cabinet, preferably occupy the space I 2 and are secured for stability to the true wall or bottom II. The energization of the lamps Il is controlled by the switch 2|, and such control of the electrical circuit is entirely automatic resulting from the mere opening and closing of the door l. The switch 2l is provided with an actuating pin or plunger 22 which projects up into the mortised seat 9 for the door lI, as seen in Figure 3, when the door is opened. In this position, namely when the door is opened, the switch 2| breaks the circuit and de-energizes the radiation lamps. When the door is closed, as seen in Figure 2, the plunger 22 is depressed by the door and closes the circuit, thus energizing the lamps.

In Figure 4 I have illustrated a schematic diagram which is satisfactory for the operation of one or more radiation lamps in a device of the character illustrated. In this diagram, conductors 23 and 24 may extend to any suitable source of electrical energy. The switch 2i is preferably in one of these wires, in the illustrated instance wire or conductor 23, between the source of energy and the first lamp connection, so that this switch automatically controls all of the lamps simultaneously. Each lamp I4 is preferably connected across the secondary of a transformer 25, and the primary of the transformer is preferably connected across the line 23-2. All such lamp and transformer arrangements are preferably paralleled across the line 23-24 on the opposite side of the switch 2l from the source of energy.

While I have illustrated a cabinet containing two radiation lamps, it will be appreciated that only one lamp or as many more as might be desired may be used in the cabinet. In operation, the present invention is extreme- It is only necessary, in connection with shoes for example, for the clerk or sales person to assemble shoes tried on but not purchased by a customer. The clerk.may then take these shoes, a pair at a time, simply open the door 'I of the cabinet, and

place a shoe 26 over each guard I4 so that both the guard and the lamp extend Within the shoe, as seen clearly in Figure l. With the shoes so placed, the clerk merely closes the door 'l and by way of the switch 2l, both lamps are simultaneously energized and emanate their bacteriadestroying rays directly into the interior of the shoes being treated. After a short interval of time, the door is again opened, thus de-energizing the lamps, and the sanitized or sterilized pair of shoes removed, a new pair substituted, and the process repeated. It should be especially noted that the guard I'I not only protects its respective radiation lamp, but also functions as a support for the article being sanitized. If any question should arise as to thorough sanitization or sterilization in view of the use of the guard I1. it is a simple expedient to turn the shoe slightly on the guard from its original position to insure direct emanation of rays to every part of the shoe. v

The cabinet 5 may have its electrical arrangement so that the wires 23v and 24 extend through a wall of the cabinet inside a cable 21 equipped with the usual wall plug 28 to permit the cabinet to be placedin a desired position adjacent any wall plug, and transported from place to place as may be deemed most expedient.

It is believed that my novel method of sanitizing or sterilizing articles of apparel is sufciently apparent from the foregoing as to render further description herein unnecessary.

From the above description, it will be noted that I have provided a novel sanitizing or sterilizing device, conveniently handled, highly effective in operation, substantially foolproof and simple in its operation, and which is highly durable and may be economically manufactured and used. It is also apparent that I have provided a new and novel method of sanitizing or sterilizing an article of apparel.

It will, of course, be understood that various details of construction maybe varied through a wide range without departing from the principles of this invention and it is, therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of. the appended claims.
