VAPORIZER.

SPECIFICATION forming part of Letters Patent No. 366,693, dated July 19, i887.

Application tiled October 13, 1886. Serial No. 216,175. (No model.)

To all whom it may concern:

Be it known that I, GARDNER M. SHERMAN, residing at Springfield, in the county of IIampden and State of Massachusetts, haveinvented certain new and useful Improvements in Deodorizing Evaporators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to deodorizing ordisinfecting vessels in which a chemical fluid is placed, and from which the vapors of evaporation are allowed to escape into the room, sewer, or other locality to be disinfected.

lFigure l is a vertical central section of the vaporizing or evaporating vessel. Fig. 2 is a plan or top view of the head of the retaining jar. Fig. 3 is a section similar` to Fig. l with the cover and tip-stopper of the jar lifted. Fig. 4. is a. cross-section of Fig. 2 on line as.

A in the drawings represents a tin or other metallic can, or ajarof glass or earthenware, having ahead, B, which is'provided with a crossbar, C. The crossbar C supports a hollow spindle, D, which is screw threaded externally and works in a thread in the bar C.

The spindle D is screwed or otherwise attached to cover E, so that the rotation of the cover will cause it to be lifted from the rim of the head B, as shown in Fig. 3.

The tip-stopper F has its seat in the cover E, and is held there by a screw-thread or in other suitable manner. \Vhen this stopper` is closed, the passage-way through the spindle D is stopped.

G indicates-a porous cup of plaster, having a baserim, l, which rim tits closely within the cup A. This leaves an annular recess, L, between the can or jar and the porous cup G.

The cavity Hin the porous cup G may be filled with a carbolic solution, or any other similar chemical in liquid form which is used as a disinfectant. This fluid will slowly percolate through the plaster cup, and the gases of evaporation will risc from the exterior of the cup in the annular space L. When the cover is tightly screwed down, the gas cannot escape; but when the cover is slightly lifted on the spindle D an openingA is formed all around the edge of the cover, from which opening the gas may escape into the room.

If it is desired to accelerate the rate of evaporation, the plug I may be removed from opening-fu1nes is desired, the cover E may be tightly closed and the stopper F removed, when the escape ofgas or vapor will be only through the tubular spindle D.

This apparatus may be used in a sick-room to great advantage, the capability for regulating the escape of the vapors with great nicety making it an excellent device for the purpose. For sewers or cesspools the plaster cup G may be used Without theinclosing-can, and a Very cheap and efficient device is thus produced.

The stopper S may be used with the cup G when the latter is inclosed in can A, when the evaporation must be entirely through the walls of the porous cup.

I claiml. The combination, with the inclosing-jar or can, of the porous cup having a flange near the bottom which fits the inclosing-can, but leaves an annular recess above the same.

2. The combination, with the inclosing-can and the inclosed porous cup, of a cover, and a spindle from said cover engaging a support on the can, by which spindle and support the position of the cover relatively to the can may be fixed and determined, substantially as dcseribed. i

3. The combination, with theinclosing-can, of the inclosed porous cup, a hollow spindle extending up from the cup, and a stopper at the top of said spindle, substantially as described.

4. The combination of the inelosi'ngcasing having an adjustable cover and a stoppered Ventilating or draft opening near the bottom of said casing, said opening communicating with the space between the casing and the inclosed cup, and the porous cup within but not entirely filling the casing, substantially as de scribed.

In testimony whereof I affix my signature in presence of two witnesses.

GARDNER M. SHERMAN.
