IDlSlNFECTlNG APPARATUS.

SPECIFICATION forming part of Letters Patent N0. 788,805, dated May 2, 1905.

Application filed November l, 1904. Serial No. 230,983.

To rtf/ when it may concern:

Be it known thatl, CHARLES J. WALZ, a citizen oi' the United States, residingin New York city, borough of Manhattan, New York, have invented certain new and useful Improvements in Disinfecting Apparatus, ot' which the'lollowing is a speciiication.

My invention relates to improvements in the class oi' disinfecting apparatus in which the disinfecting 'fluid is gradually fed from a reservoir to the open air for evaporation and delivery in small quantities to the place to be disinfected; and the object of my invention is to provide means for controlling at will the amount of fluid to be distributed and to provide for the more equal distribuion of the iiui'd for evaporation.

My invention comprises a casing provided with a Huid-containing reservoir, a fluid-1e ceiving chamber, means to regulate at will the height of the iluid to be delivered to said chamber from the reservoir, means for transferring fluid from the chamber, and means for receiving such fluid and causing its distribution. Y

The invention also comprises the novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein- Figure 1 is a side elevation, partly broken, of a disinfecting apparatus embodying my invention. Fig. 2 is a plan view thereof, part of the cover being removed. Fig. 3 is a vertical section substantially on the line 3 3 in Fig. 2. Fig. 4L is a detail of a modiiied form of the valve for controlling the liow ot' Huid from the Y main reservoir to the receiving-chamber, and

1 are perforated, as at 1*. Above the partition 3 is a main fluid-containing reservoir 5, which is shown contained between an upper partition (i, an inner wall 7, the lower partition 3, and the outer walls or sides of casingl. The wall 7 opens through the top partition 6 and 'fo rms a chamber 8 in conjunction with part of the casing 1 and the lower partition 3. (See Fig. 2.) The wall 7 at its lower portion has a vertically-disposed opening 7, which in Fig. 3 is shown in the form oi' a slot providing com munication between reservoir 5 and chamber 8, and 1 provide a valve device (shown located in chamber 8)to control the flow oi'iluid from reservoir 5 to said chamber'. For this purpose I have shown a tube 9 disposed vertically in chamber Sand provided with opposed openings 9 9", shown in Fig. 3 in the form oi' vertically-disposed slots on opposite sides ol' tube 9, said tube being secured iiuid-tight to the wall 7, so that its opening 9 alines with opening 7 a in said wall to permit the passage of 'Huid from reservoir 5 to chamber 8. Vithin tube 9 is a valve stem or rod 10, which is screw-threaded to mesh with corresponding threads within tube 9, said tube being' threaded throughout its length, the threads on rod 10 extending along' the same suiiiciently far to enable said rod to be screwed down to positively close the passage through openings 9 9b throughout their whole length. Rod Il() may have a squared .end or the like 10 to receive a key inserted through the open end of chamber 8 to permit operating said rod. When rod 10 is screwed outwardly the desired distance, iluid from reservoir 5 will ilow through opening 7lL 9" 9" into chamber 8 to the height at which the lower end of rod 10re mains. Instead oi' having slots 9u 9" in tube 9 said tube may be provided with a series of vertically-disposed perforations, (indicated at 9.)

The partition 6 is shown provided with an opening 6", having a threaded neck 6, reeeiv ing a threaded plug 11, that is'provided with a bore 11 opening through the bottom and one side of said plug, whereby when said plug is screwed down tight, as in Fig. 3, the passage of air through opening 6:x will be prevented, but when the plug is screwed outl rlhe details of construction shown and dewardly sufficiently far air may enter reservoir 5 through bore 11. By unscrewing plug 11 so that air may enter the reservoir said reservoir may be filled by screwing rod 10 outwardly and pouring the fluid into chamber 8, which will pass thence into the reservoir. If preferred, however, the reservoir may be filled through the opening 6, in which case the plug 11 may be removed, or, if preferred, a screwcap 12 may be provided on neck 6b, as in Fig. 5.

l/Vithin chamber 8 is a tube 13, that is shown extending nearly to the .top of said chamber and at its lower end opens through the partition 3, and at 14 is a wick that passes through tube 13, preferably extending therefrom into chamber 4, part of said wick also being located in chamber 8 and extending down substantially to the bottom thereof, as in Fig. 3. By means of said wick the fluid from chamber 8 is by capillary action carried through tube 13 and delivered into chamber 4. /Vithin chamber 4 is a fluid receiver and evaporator 15, which is shown in the form of a shell, having relatively large perforations 15, a space 4 being provided between shell 15 and the walls of casing 1. The top 15b of shell 15 is shown located below the Lipper edge 15c thereof, providing a shallow pan or receiver 15d for liquid delivered thereto by wick 13, the lower end of which wick is above such pan. At 16 is a drip-tube extending from the bottom 2 of casing 1 and communicating with space 41.

In the operation of this device the reservoir 5 is filled with liquid, the valve rod or stem 10 is raised to the desired height, so that liquid will enter chamber 8 to a height corresponding to the bottom 0f stem 10, and the wick 14 delivers such iluid to the pan or receiver 15d, which fluid spreads out thereon and when said pan or receiver is filled the liquid overflows and slowly travels down the outer wall of shell 15, where the free circulation of air through the openings 15a assists in causing relatively rapid evaporation of such Huid, and the excess liquid flows upon the bottom wall of chamber 4a and passes through drip 16 to the place to Vbe disinfected. The rapidity of delivery of fluid caused by wick 14 may be controlled at will by raising or lowering the valve rod or stem 10, whereby to increase or decrease the size of the opening or communication between reservoir 5 and chamber' 8, to thereby regulate the height of fluid in said chamber, for when no air is admitted to the top of reservoir 5 the fluid in chamber 8 will only rise substantially to the height of the lower end of rod 10, even though the liquid in reservoir 5 is above the lower end of said rod, and the deeper wick 14 dips into fluid in chamber 8 the faster will be the feed of liquid by said wick and the less the wick dips into said fluid the slower will be the feed of iiuid by the wick.

scribed may be varied without departing from the spirit of my invention.

A disinfecting apparatus comprising a fluid-reservoir and a chamber for communication with each other, means to control at will the height of fluid in said chamber flowing from said reservoir, means to cause evaporation of fluid from said chamber, and a fluidreceiver beneath said reservoir and chamber provided with a top and perforated side walls beneath said top, substantially as described.
