CABINET Application filed October 31,1927. Serial No. 230,079.

I zation is brought about throughthe opening and closing of the door to the cabinet.

Cabinets of this character ,as heretofore constructed, have been provided with apparatus/for spraying a sterilizer into the air of the cabinet, but as a rule the apparatus has required a separate operation, and was in no Way dependent upon the insertion or removal of the articles to be sterilized. One of the primary objects of the present 1 invention is the provision of a cabinet, having holders for supporting a plurality of similar articles, such as toothbrushes or the like,in position to be sprayed with a sterilizer,-'wherein the spray is co ordinated with the insertion and removal of the'article.

Another object is the provision in such mechanism of means for simultaneously treating two articles to be sterilized with the 5 sterilizing solution. 2

mechanism for the sterilizing liquid, operated to eject a spray of the liquid upon two symmetrically arranged articles whenever the door isclosed, and operated by the closing movement'of the door. Another 'object is the provision of an'air compressor normally 1 operated to expanded condition, and closed by the movement of the closingdoor thereby to relieve the opening 3 door from' the burden of expanding the bellows.

Another object is the provision of a tank or reservoir for the sterilizing liquid so arranged as to occupy a minimum of room, to

49 be as close as possible to the point where the spray is delivered, and of a nature such that a minimum depth of liquid is needed in the tank, and wherein substantially all of the liquid may be ejected by the spray.

Another object is toso arrange the parts as toenable removalof the spraying apparatusincluding thetank and the holders for the articles, as a unit, from the cabinet. 1

Another object is to provide in such acabinet of'a minimum-size to contain a selected Another object is the provision of spraying number of articles for. which, it is intended, a maximum of space for receiving related articles, such as tubes of toothpaste, and the like. V p

With these and other objects in view the invention consists in theconstruction and novel combination of parts fully described hereinafter, illustrated in the accompanying drawings, and pointed out in the claims appended hereto, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims, may b'e'resorted to without departing from the spirit of the invention.

In the drawings forming a part hereof Fig. 1 is a frontview of the improved cabinet.

Figs? and 3 are sectionson the lines 2-2 and 3-3 respectively, of'Fig. 1. q

Fig. dis a section on the'line 4 fl of Fig. 3. Fig. 5 is a perspective view of the cabinet with the doorpartially open. In the present embodiment of the invention, a suitable case is provided, comprising a body 1, and a base 2, the body having an opening 3 at the front thereof, which is normally closed by a door 4:, hingedto the easing at one end of the casing as indicated at 5. The door has the usual knob. 6'f0r manipulating the same, and preferably a mirror? is arranged on' thedoor, themirror beingheld in a frame 8. r

As shown in'Figs. 3 and 5, the base or bot tom 2 of, the cabinetis of somewhat greater area than the cross-section of the body, and

the saidbottom may be provided with suitale openings, for enabling it to be connected to a fixed support, as for instance awall.

A support for the sterilizing apparatus,

and for the articles to be sterilized is arranged within the casing. his support comprises a tank or reservoir 9, and a hood 10 of substantially L-shape in cross section. A'hood is'connected with the tank, the hood comprising a front wall 10, a top wall 11,'ends 12, and flanges 13 and 1d on the respective walls 10 and 11. The flange 13 is inturned, and is secured to the top of the tank 9,the said top being plane and horizontal as shown in Fig. 3. The other flange'l l is outturned, and has openings for receiving fastening means to connect it to the bottom 2 of the casing, the

fastening means in the present instance being bolts and nuts 15 as shown.

An air compressor is arranged within the hood, a bellows in tae present instance comprising a fixed member 16 connected to the end walls 12 of the hood by screws indicated at 17, and a movable member 18 which is hinged at its bottom to the fixed member, the hinge being indicated at 19. A flexible cover ing 20 is arranged over the hinge, and connects the two members of the bellows at the bottom. A similar covering 21 connects the tops of the members; and there are other flexiblecoverings at the ends, all being ar ranged to enable opening and closing movement of the bellows.

The member 18 of the bellows has one or more openings 22, which are normally closed by a flap valve 23 011 the inner face of the member. The arrangement is such as to enable the free passage of air into the bellows when it is expanded, but to prevent the escape of air when it is contracted. The bellows members are normally constrained toward open position by a spring 24. This spring is substantially U-shaped as shown in Fig. 2, the body thereof having a coil, while the arms are connected to the respective members of the bellows.

A plurality of holders 25 is supported on the wall 10, each of the said holders being constituted by a pair of spring clips, and each holder is adapted to support, in the present instance, a toothbrush 26, with the handle depending below the holder, and with the brush above the holder. Preferably the holders are even in number, six in the present instance, and the articles are arranged with the surfaces to be sterilized adjacent, as clearly shown in Fig. 1.

A discharge pipe 27 leads upwardly from the front of the tank between each pair of holders 25. As shown, each pipe is the liquid conduit of an atomizer, the air conduit indicated at 28 leading from the bellows through the fixed member to a connection with the spray nozzle 29 of the atomizer. The arrangement is such that when air is forced through the pipe 28, liquid is drawn through the pipe 27, and sprayed through the nozzle 29 The bellows, as previously mentioned, is normally moved to open position; by the spring 24. It is contracted or compressed by a pair of similar springs 30. As shown in Figures 3 and 4, each spring bears at one end against the top of the member 18 of the bellows, while the other end has a coil encircling a. shaft 31 held in angle brackets 32 on a plate 33 secured to the rear wall of the tank 9, and extending above the wall as shown. One end of the shaft has secured thereto a wheel 34 provided with radial openings 35, in which may be inserted a pin 36, to hold the shaft against the turning movement of the spring coils. Referring to Figure 4, it will be seen that the ends of the springs pass through openings in the shaft, and the arrangement of the coils is such as would turn the shaft from left to right. However, the pin restrains this movement, and by engaging it with different openings, the tension of the spring may be nicely adjusted.

The end of each spring remote from the shaft has an eye as shown in Figures 2 and 3, and the eyes are arranged between a pair of plates 37, rivets 38 or the like being passed through the plates and through the eyes to connect the parts. A pin 39 depending from the end of a lever 40 bears against the front plate 37. The lever is pivoted at 41 to the wall 11, and the outer end is connected by a link 42 with the door 4, the link engaging an angle bracket 43 on the inner face of the door.

It will be evident from the description that whenever the door is opened, the bellows will be opened, to draw in a supply of air through the opening 22. The opening of the bellows is assisted by the spring 24. 1 As soon as the door is released, the spring bearing against the depending pin of the lever operates the lever to close the door, and operates the bellows to discharge the air, which must pass through the air pipes 28 of the atomizers. The discharging air carries with it a spray of liquid in the tank 9, and this spray isdischarged onto the articles supported by the holders, in the present instance onto the bristles of the brushes. It will be evident that whenever the door is opened to insert or remove an article, the spray will be operated. Referring to Fig. 3, it will be noticed that the tank is relatively shallow, and that the bottom inclines downwardly toward the front. It will also be noticed that the front wall inclines rearwardly and downwardly, and that the pipes 27 lie along this inclined front wall and extend to the bottom of the tank at the deepest portion thereof. This arrangement enables with a height of cabinet no greater than necessary to contain the articles, a relatively large space for the reception of allied articles, such as dentrifices. The arrangement also brings the supply of the liquid as close as possible to the point of discharge.

A filling opening closed by a plug 44 is provided in connection with the tank, to enable the contents thereof to he removed, and the end walls 12 of the support, as well as the end walls of the casing body, having openings as shown for ventilation. It will be understood that the cabinet may be of any desired material, and it may be of any preferred shape. The exterior thereof may be suitably ornamented, if desired.

It will be obvious that any preferred cona sterilizing apparatus including a plurality of atomizers, a tank, and a bellows common to all of the atomizersto operate the same, a plurality of article supports for each atom, izer, mechanism operated by the opening and closing of the door to operate the bellows, the
