2 Claims.

This invention relates to a deodorizing device, of the type in which a specially treated material is burnt to produce the desired deodorizing eifect, and it has for one of its objects the provision of an improved arrangement in which a combustible deodorizing material is protected, used, and its combustion controlled in a simple and efficient manner.

The invention is particularly concerned with the provision of a portable unit that can be provided with a. supply of specially treated deodorizing material which is fed by suitable means into a combustion area where it is ignited, and means are provided to insure burning of the material only in predetermined amounts, at the conclusion of which the material is extinguished automatically, or if desired it may be extinguished, before the predetermined amount has been consumed, by simple manipulation of portions of a structure designed for this purpose. Likewise, the device can be manipulated from time to time after the material has been ignited to provide for continuous burning and deodorizing eifect for as long a period as desired.

In the drawing:

Fig. 1 is a perspective of a device embodying the invention;

Fig. 2 is a medial vertical section of the device shown in Fig. 1; and

Fig. 3 is a plan of a sheet of material in blank form from which the casing of the device can be constructed.

In practicing the invention a casing 10 is provided and opposite sides l2, back l3, and bottom [5 of such casing can be stamped from a single sheet of material iii in the form shown in Fig. 3. A receptacle ll adapted to contain matches, can also be stamped as an integral part of the blank sheet of material and is provided with a neck l9 connecting it to the bottom l5. In order to complete the contour of the receptacle marginal flanges 20 are provided which are bent into the position shown in Fig. 1. Likewise, a tray 22 can be stamped from the sheet of material and preferably it is severed and dished during the stamping operation in order that it can be removably supported upon the bottom I5 in the position shown in Fig. 2.

A channel 23 having a front wall 25, rear wall 26 and bottom 21, is secured by means of rivets 28 to the back of the casing and the upper portion of its rear wall 23 is bent to form a semicylindrical hinge channel 29, the ends of which are materially spaced from the side walls 12 (Fig. 1). A complemental semi-cylindrical hinge channel 30 connected to the hinge channel 29 is formed upon one edge of the cover 32 which is thus hinged to the upper portion of the casing and provides a closure therefor. An angular flange 35 at the lower or free end of the cover is adapted to snap beneath the front edge of the bottom [5 of the casing, and thus releasably maintain the cover in closed position. Suitable openings 36 are formed through the cover to communicate with a combustion chamber 34 that is defined by the cover 32 and easing Walls I2l3l5. 1

The front wall 25 of the channel 23 is provided with forwardly extending opposed flanges 31 which rotatably support a pair of rollers 40 and 42 journaled therein transversely of the casing between the casing walls 12. The surfaces of the rollers are gear-like in form and have relatively loosely intermeshing teeth 43. The upper roller 40 extends through one of the walls l2 and is provided with a manually operable knob 45, which provides means to rotate both of the rollers.

A spool 46 is disposed loosely in the channel 23 and it has a roll of fibrous material 48 in strand form wound thereon. This roll of material is thus separated and insulated from the combustion chamber 34 by the Walls 2621 and the contiguous wall portion of the closed casing cover. The free end of the fibrous material is directed between the rollers 40 and 42 and can be drawn therebetween by turning the knob 45 until a suitable length depends from the rollers as indicated in Fig. 1. In order to facilitate the movement of the fibrous material and to direct it toward the central location with respect to the length of the rollers 46 and 42, a notch 49 is provided in the front wall 25 of the casing channel 23, and the material is guided therethrough.

The fibrous material, which can be in rope or strip form, is treated by impregnating it with a suitable deodorant, such as resins, and is adapted to be ignited by applying a lighted match to the end projecting from the rollers. fibrous material which has been treated with a deodorant is of such nature that it will glow without blazing, and'thus, will burn or smoulder slowly.

When the cover 32 is closed the fumes or smoke from the smouldering material escapes from the casing through the openings 36 in the cover. Since the roller teeth 43 compress: the fibrous material relatively tightly, the latter will not burn or smoulder back toward the spool 46 beyond the portion thereof projecting forwardly from the location of clamping of the rollers. Thus a short or relatively long length of material can be ignited at a given time, depending 5 upon the period of time it is desired to maintain the glowing and smouldering action. The ashes of the burning material drop into the tray and can be disposed of by removing and emptying the tray at any time in. any convenient manner. In order to extinguish the embers of the fibrous material at any time after the latter has been ignited, the rollers 40 and 42 are rotated to draw the smouldering portion of the material between the teeth 43 whereby the pressure exerted at this location causes the embers to be immedim u l- 11 therefrom, and disposed inside t 15 ately extinguished. On the other hand, thelmob 45 can, before the material burns to the rollers 1 30 saturated with the deodorant in which the flexible material has been treated 'or impr ated. Accordingly, a very eflicient method of "deodorizing is insured by the thoroughly'saturated fumes which escape through theopenings in the cover into the room or other locationin which the :de-

viceis used.

This device can be secured upon any smooth wall or glass surface by meansof a vacuum cup 50 secured to the outside portion of the casing ;9 andcan be employed for deodoriz'ing purposes in various locations and under variouscondi'tions.

Although only one form of the invention has been shown and described in detail, it will be apparent to those: skilled in the art that the invention is not so limited, but that various changes may be made therein without departing from, the 5 spirit of the invention or from the scope of the appended claims.

I claim:

l. A deodorizing device comprising a casing having a combustion chamber, a container in 10 the casing separated by its walls from. the combustion chamber, a roll of deodorizing material pylfl'ljstrand form enclosed and supported by the container, said container having flanges extendcombustion chamber, a pair of toothed intermesh'ing rollers for clamping the deodorizing material therebetween and rotatably carried by said flanges tofeed said material into the combustion chamber, means for operating the rollers anda .cover closing the container and having a; plurality of openings communicating :from the combus'tion chamber to the atmosphere to admit air for combustion and to. allow the deodorizing fumes resulting from the combustion of the deodorizing material to escape.

2. A deodorizing device comprising a casing having a combustion chamber, a container holding a roll of deodorizing material, rollers engaging between them an end of the material to feed it into :the combustion chamber, means extending from the container for 'rotatably supporting said rollers, a hinged top closing the container and extending over the combustion chamber having :a plurality of openings in that portionvof the top covering the combustion chamber; serving to admit air for combustion and provide exit for the deodorizing fumes.
