Patented Dec. 22, 1931 UNITED STATES ALBERT BACHRACH, or DECATUR, ILLIIv'o'Is J FURNITURE Application filed August 1, 1 328 Serial No. 296,658;

Another object is to provide improved means of the kind describedfor efliciently disinfecting upholstered furniture, for the prevention and destruction of moths, insects, etc., thus contributing to the comfort of the user and the preservation of the upholstery.

Other objects will appear hereinafter.

In the drawings Figure 1 is a perspective view of a sofa wherein my invention is embodied.

Figure 2 is a perspective view of an up bolstered seat showing my invention in a slightly modified form.

Figure 3 is an elevational view, partly in section, of an upholstered chair with my invention applied thereto.

Figure 4 is a perspective view of my device shown as it appears detached from an article of furniture.

Figure 5 is a fragmentary enlarged sectional detail view of a valve employed by me in connection with my invention.

With more particular reference to the drawings wherein similar characters of reference indicate correspondingparts in the several views, A designates a sofa of conventional type having a seat 9, curving arms 10 and a back 11. In the rear of the arms, back and seat. valves 12 are provided which connect with pipes 13 having perforations 14, the pipes extending through the arms, back and seat, as shown in Figure 1.

In Figure 2 the pipe 13 is shown extending in helical form, the valve 12 projecting slightly beyond the outer edge of any convenient portion of the seat member 9 shown.-

Figure 3 shows my invention applied to a chair, the back thereof being shown in section with the pipe 13 extending upwardly therefrom from the valve 12.

In Figure 4 a system of intercommunicating pipes 13 is shown to which access is had by the valve 12. .The relative position of this system of disinfecting pipes to an arm chair is indicatedby the dottedlines which roughly indicate'the said chair; Y

- \The'valve 12 through which any suitable disinfecting medium, such as sulphuiidioxide, 'hydrocyanic acid gas, formaldehyde, etc, is injected into the pipes and thence through the perforationsinto theupholstery of the furniture, is shown in Figure 5; Thisgv'alvealsoserves to prevent the'return of the liquid or gas injectedv to the'out'er air by reason of back pressure from. within, thus permitting the use ofthe powerfubdisinfectantsindicated..- Figure 5 .designates the valve as a whole, which is provided' with a circumferential flange. 15 and an inner bore 16 having an "inner tapering portion 1-7 which isagain' widened toprovide a seat 18 for a ball 20 closingfa widened chamber 19 into which the bore 16 communicates.

Byinspectionofthis figure it will be seen ter" serve :as a means 50f "communication be;

tween the" channels of the pipe- 13 and the widened chamber 19. The plug 23, which isthreaded, also serves to connect the valve apparent by the brief explana- Assuming the device to be installed in the articles of furniture illustrated in Figures 1 to 4 inclusive, it will be desirable at periodical intervals of time, which will differ at different seasons of the year and in different climates, to connect the valve 12 with any suitable means for injecting disinfecting gases of the type indicated above or air laden with insect destroying powder. In practice I have found it eflicie'nt and con venient to connect the valve 12 to cylinders of compressed gases of the types indicated. By opening up the valve of the cylinders to a suitable degree, a rush of the'gaseous disinfectant through the valve '12 and through the communicating pipes, and thence through the perforations 14 into the 5 upholstery, will occur. If desired, the furniture in connection with this process may be simultaneously sweetened by the intermingling of some gas of agreeable odor with the disinfecting gas, or this may be done subsequent to disinfection. I have found the use of gases and power laden air preferable to liquids, although these of the 7 more volatile type may be employed.

The invention is especially valuable in 15 such climates and localities where vermin prove :an ever prevalent pest,'this being :particularly true during the :summer months and .in the tropical climates. I am aware of upholstered furniture wherein has been 3 incorporated means which are brought into playwhen the furniture is in .use-,'the aprinciple involved .beingthat of the bellows; The. chief disadvantage to ithis'method is that the source of supplyis quickly-ex- 'haustedif the articles of furniture are used frequently; It is also impractical to en ploy such powerful means of vermin eradication, as has been herein indicated feasible, for obvious considerations. I 7 .It will be obvious that the. invention is susceptible of some modification and change, hence Iv donot confine myselfliterally to the exact details :as 'set'forth, but desire to avail myself of such modifications and variations 35 as fairly fall within the scope er the appended claims.

' What I laim as new and desire to secure by LettersfPatent is:

An article of furniture of the character 4 described, .comprisingiza framework having upholstered portions, and 5 a plurality of rigid interconnected tubular members dis posed within the upholstering of said upholstered porIt-ions,f said tubular members provided with a plurality of perforations and having a common inlet and check valve connection, whereby a gaseous disiniectant maybe administered under pressure-and distributed through said upholstering.

I In testimony whereof I' have "signed my nameto'thisspecificat-ion.
