WESLEY R. GOODWIN, OF DECATUR, ILLNOIS.

STERlLIZlNG-CABlNET.

eacrrrcn'rron forming pm of Letters Patent No. 649,512, dated may 15, 1900. Application lezl October 6, 1899. Serial No. 732,760. (No model.)

. a citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented certain new and useful Improvements 'in Sterilizing0abinets; and I do hereby declare the following to be a full, clear, and exact description of the invent-ion, such as will enable others skilled in the art to which it appertains to make and I desire it understood, however, that the use of the invention is not limited, but the same can be employed for various purposes. Heretofore it has been found entirely impractical to utilize awet sterilizing agent or material for sterilizing steel implements or toilet articles, such as brushes, &c., owing to the fact that the moisture carried by the steam, as an example, necessarily damages the articles. It has also been found impractical to use heat, inasmuch as the degree of heat often injures the articles. My invention is designed to overcome the objections to the above type of sterilizcrs and is designed'more particularly for use with chemicals or disinfectiug agents the vapors of which are generated bythe application of a'flame or relatively-small amount of'heat and penetrate the entire cabinet, ster-V ilizing the articles therein. L

To this end the invention comprises a cabinet conveniently formed of a series of drawers formed so that the sterilizing agent will penetrate the same, sterilizing the articles con` tained therein without heating or dampening the same.

Theinvention further consists in the particularconstruction and arrangement hereinafter described.

In the drawings l have shown the steril-` net.

struction can be made without departing from the nature and principle of the invention.

In the drawings, Figure 1 is a front elevation, and Fig. 2 isa longitudinal vertical section. y

ln the drawings. A represents the outer casing of the cabiuet,comprisin g a closed back and sides.

B designates the front door, which is couveniently hinged at one side. f

The cabinet is formed with a series of transverse supports C and a series of upright su pports C', the same being dispersed at proper points to form guides and supports for the various receptacles or sliding drawers. These drawers conveniently consist of four drawers substantiallyrectangular incross-scction arranged in pairs on opposite sides at the bottom, as at D, leaving an unoccupied space E between the lower two of the series and at the center-of the cabinet. The sides of the lower two of the drawers D are perforated, as shown atd. Above the space E is an `oblong drawer D2, having a perforated bottom; Above the drawers D and D2 are two oblong drawers D3, having perforated bottoms, and above these are conveniently arranged four relatively-smaller drawers D4, each of which is provided with a perforated bottom. Each of the drawers is supported on a rest, and they are separated by the uprights, so that they' `which is an escape-pipef, having a damper f' therein.

The cabinet is conveniently supported on suitable legs a. and has a bottom A', formed with a central opening a' therein, located at the center of the space E. Over thisopening is placed a metallic diaphragm H, the same being supported on.` legs h to form a clearance between the same and base of the cabi- In line with the opening his placed the burner of the lamp or gas-xture, and below the diaphragm are placedsuitable receptacles containing a vaporable sterilizing chemical. The lampl is of any convenient style or formation and preferably of the alcohol-burning type.

In practice the smaller drawers are designed to contain the implements, while the larger IOO ones lare designed to contain towels or other' cloths, fabrics, dto. rIhis, however, is Wholly arbitrary. The cabinet is designed to be un.-

A the lower draw ers and perforated bottoms of the upper drawers, thoroughly satnrating the interior of the various drawers and sterilizing the articles therein contained. By governing the damper in the exhaust-pipe the movement cf the sterilizing-vapor is governed,and the pipe may be conducted to any convenient point of discharge. In practice I purpose to employ duplicates ofLthe drawers, so that one canbe removed and the contents, as a soap-dish, with necessary brush, and another replaced while the contents of the one removed are being used.` This, however, is entirely arbitrary. IIaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a sterilizing-cabinet comprising a series of separated drawers having perforated bottoms and an aperture in the base of the cabinet, a burner in line with-the aperture, a diaphragm above the aperture and in line therewith, means adapted to contain a suitable sterilizing medium situated in the line of draft from the burner, andan escape ati the top of the cabinet and a governor for the same, substantially as described.

2. In. a steriiizing-cabinet, the combination with the walls of the cabinet, a series of `d rawers therein having perforated bottoms and arranged to leave a heating-space therebelow, of drawers in the base of the cabinet having perforated sides exposed to the heating-space and means for supplying heat comprising a burner leading to an opening in the cabinet, la diaphragm in the cabinetabove said opening, and means located near said diaphragm and in the line of draft from the burner, adapted to contain a suitable sterilizing medium, substantially as described.

3. In a sterilizing-cabinet, the combination with the walls, of a series of perforated drawers within the cabinet, arburner communieating with the cabinet through an aperturev in the bottom thereof, and means adapted to support a suitable sterilizing medium'in the line of draft through the cabinet, a domeand damper-exit from the dome, substantially as described. I

4. In a sterilizng-cabinet having a suitable outlet, the-combination with the walls of the cabinet, drawers supported therein and arranged to leave a centrally-disposed heatingspace in the lower portion of the cabinet and perforated respectively at the sides and bottoms to permit a thorough circulation, means adapted to contain a sterilizing medium at the lower portion of the cabinet, substantially as described. v f

Intestimony whereof I aix my signature in presence of two witnesses.
