Application filed November 7,1890. Serial No. 370,596. .(No model.)

To all whom it maij concern:

Be it known that I, Jesse P. Robert, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of 5 Pennsylvania,have invented certain new and useful Improvements in Disinfecting Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled io in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, xvhich form a part of this specification.

My invention relates to an improved disin15 fecting apparatus; and it consists in the certain details of construction hereinafter specified.

In the accompanying drawings, Figure 1 is a central sectional elevation of my improved 20 apparatus as constructed in accordance xvith my invention. Fig. 2 is a plan view of the same, a part of which is shoxvn in section.

Toput my invention into practice,! provide a cyliudric metallic vessel a, having a closed 25 base and a perforated concave top b, through xvhich a liquid disinfectant may escape. Centrally located xvithin this vessel a is a coneshaped chamber c, which forms an annular space within thevessel a. The space between 30 vessel c and the outer wall is filled with asbestus, mineral wool, or other like indestructible and porous material cl. This annular space and the interior of the chamber c are in communication with each other by means of 35 ports or openings e, formed through the base of the partition. This cone-shaped chamber c is provided with'an opening at the top and fitted xvith a screw-cap f to render the same air-tight. At the back of the apparatus is secured a disk g, having screxv-holes formed 40 therein for the purpose of attaching, the apparatus to the xvall of a room. A small ring h, attached to the screxv-eap f, serves as a means for suspending the same to a hooK or nail. Surrounding the perforated top of the 45 apparatus is an annular rim i, xvhich will prevent the fluid from the apparatus from runnine doxvn the outside.

In operation the cap f is removed and a liquid disinfectant placed in the inner chain- 50) ber c and the cap f replaced, xvhich renders the apparatus ready for use. The liquid gradually saturates the fibrous material, and the vapors arising escape into the room.
