` FUMI noesae.

Application filed February To all whom it may concern:

Be it known that I, PERRY S. BAUER, a citizen of the United States, residing at Chicago, in the county of Cook and State of llllinois, have invented new and useful Improvements in Fuinigators, of which the following is a specification..

rlhis invention relates to'fumigators and tudinal sectional view of a fumigator taken composition lar 4bead or rib 12 lar view showing the device ready for use;

and Fig. `3 isa sectional elevation on .thev

line 3 3 of Fig. 2.

Referring to the drawings 5 designates a shell preferably cylindrical in forni and vcomposed of sheet-metal or other non-combustible material. A receptacle or container 6 is fitted within one of the open ends of .the shell, an integral rib 7 being provided on theiw'all of the shell to prevent the container from slipping too far into the shell, and adapted to contain a charge 8 of volatile vdisinfecting material in solid form. The

be composed of any preferred but preferably consists of a of solid character which, when heated, will give oif formaldehyde vapor.

A cap 9 adapted to fit the end of the shell containing the charge of disinfectant contains a mass or charge 1() of solid hydrocarcharge may disinfectant bon such as paraffin and a wick 11 embedded in the charge', said wick being preferably formed of paper or other combustible inaterial which will initiate the combustion of the charge of paraffin. An internal annuis provided in the cap to prevent the charge waved. Similar of combustible materialv from, dropping out. when the cap is. rev-yf."

in the container to insure the retention of the charge ofdisinfecting material, if desired.

It will be observed from Fig. l tha-t the cap fits tightly over the end of vthe disinfect-ant container and while the rib 13 limits thetelescoping ymovement of the capon the shell it permits the edges 14 of the receptacle and shell to enter the paraiiiii contained in the cap suiiiciently to form an air-tight \seal for the container. The advantages of this hermetic sealing ofthe container willv be obvious when it is remembered that the charge consists of a very volatile disinfectant which would be vaporized and lost to 'the atmosphere long' before the device was ever used if no effective sealing were provided.` The device is marketed with the charges of disinfectant and combustible inaterial already" disposed in the container and the cap, respectively, and the cap being aiiiXed to the shell? as shown in Fig. 1, the article may be shipped, handled and eX posed without Vdanger of injury to Ieither of the contained charges and Without the liability or possibility of the disinfectant becoming vaporized prior to lthe removal -of the cap.

When the-article is to be used the cap is removed from the container end of the shell and is applied to the opposite end, as shown in Fig. 2. In this.po'sition of the parts the bottoni of the container constitutes a crownsheet which is exposed to the heat generated in the combustion chamber formed by the portion ofthe shell below the container 6. The charge of ooiiibustiblel material may now be ignited by applying. a flame to the wick, sufficient oxygen being supplied to the cornbustion chamber through the perforations 15 to properly support the combustion. The heat generated in the combustion chamber lcauses the charge 8 to give oif formaldehyde vapor which escapes from the open top of the container to the room to vbe disinfected. The charges of vaporizable and combustible material are preferably so proportioned thatthey will be consumed simultaneously, leaving only the non-combustible metallic parts which, being of comparatively inexpensive construction, may be discarded after the device has been used. s

.The edges of the end of the-shell opposite 'the .container are preferably'rolled inwardly ioo los,

at 16to present a smooth surface and obviate the liability of any one cutting themselves in handling the article.

Various changes yin the size, shape and proportion ofthe various parts shown and described may be made, as will be apparent, without departing from the spirit of the invention.

I claim:

l. A fumigat-or comprising a shell, a disinfectant container carried thereby, and a cap containing a Wick and a charge of combustible material normally forming a seal for said container, said cap being adapted to be disposed beneath the container for vaporizing the disinfectant therein.

2. A fumigator comprising a shell, a receptacle containing a charge of violatile disinfectantsituated near one end of the shell,

a cap\ containing a Wick and a charge of combust'ble material adapted to fit over 1 either end of said shell'to form a seal for the disinfectant receptacle and to supply heat to saidreceptacle to vaporize said disinfectant, respectively.

3. A fumigator comprising a shell provided at one end With an open top receptacle containing a charge of volatile. disinfectant, and 'a capv containing a Wick and a charge of solid combustible material adapted to fit each end of the shell to form a seal for the disinfectantl receptacle and to subsequently serve as a 'burner to heat said receptacle and Vaporize the disinfect-ant contained therein.

4. A fumigator comprising a shell, a disinfectant receptacle arranged within said shell adjacent one end thereof and containing a charge of volatile disinfecting material, and a cap containing a Wick and a charge of combustible material in solid form adapted to tit both ends of said shell, said cap when fitted upon one end forming a seal for the disinfectant receptacle and when fitted over the other end serving as a burner toheat saidreceptacle and volatilize the dis infectant contained therein.

5. A fumigator comprising a shell carrying a charge ofl disinfecting material, and a cap containing a Wick and a combustible charge consisting of a body of solidified hydrocarbon, said cap being adapted to Iit either end of the shell, the end of the shell being embedded in the hydrocarbon. when the cap is disposed over one end of the'shell thereby forming a hermetic seal for the dis infectant contained in the shell, the cap.

when fitted upoli the opposite -end of lthe shell serving as a burner to heat the disinfectant and cause the same to be volatilized. G. A fumigator comprising a shell having a charge of disinfecting material, and a cap carrying a charge of combustible material and a Wick, said cap being adapted to lit one end of the shell to form a seal for said disinfecting material and to be detached therefrom and positioned beneath .the other end rof the shell for vaporizing said disinfecting material.
