    W 23,739 A.D. 1901 Date of Application, 22nd Nov., 1901—Accepted, 31st. Dec., 1901 COMPLETE SPECIFICATION. Apparatus for Destroying* Bugs and other Insects Infesting Dwellings and like Places. Constant Mattiiey-Meier, of 25 Steinenoorstadt, Bale, Switzerland, Master Caipentei, do hereby declare the nature of this invention and in what manner the same is to be performed to be particularly described and' ascertained in and by the following- statement. 5 10 lo 20 1 his invention relates to the destruction of bugs and other insects infesting dwellings and like places and has for its object the construction of an apparatus foi effecting the purpose by means of a poisonous gas produced by the complete combustion of sulphur or other substances m a closed chamber. It consists y . a 1^ ^ ^ d o f pan supporting near its upper part, a truncated conical envelope of sheet iron, at the lower part of which are provided channels or other apertures adapted to ensure the entry of the air for combustion into the apparatus ; the said tiuncated conical envelope, carries an internal grate or sheet iron per¬ forated annular disc, designed to receive the sulphur or other material to be burnt, and connected to a kind of vertical central chimney preferably of a tiuncated conical form, which, is prolonged towards the top above the said grate designed to receive the sulphur or other material. This chimney will preferably be connected below the said grate designed to receive the sulphur or other material to a second grate or perforated annular sheet iron disc, also carried by the truncated conical envelope the chimney being pierced with holes around the whole of the circumference in that portion which lies between the said grates or per¬ forated discs. this chimney is preferably crowned by a hood or cap perforated with holes and at the same time the said truncated conical envelope is surmounted by an annular hood held at a certain distance from its upper end and crowned by a 25 hood of its own so as to prevent the flame developed by the combustion of sulphur or other material being able to attain a great height above the apparatus and thus remove any danger of setting fire to the apartment. In the drawing annexed a form of construction of the apparatus is given as an example 30 Figure 1 is an elevation. Figure 2 is a vertical section. Figure 3 is a plan, and Figure 4 represents a horizontal section on the line ,i‘, of Figure 2. a is the pan provided with three detachable feet b which simnlv engage in 3; sockets arranged on the bottom of the pan. Just below the upper end of the pan an annular ledge c projects inwards on which rests the lower pai r of a truncated conical envelope of sheet iron d, corrugated at its loAvest part, so as lo form nearly vertical channels arranged to ensure the entry of the air for combustion into the apparatus in a nearly vertical direction. This truncated 40 conical envelope d has two internal horizontal ledges f r on which rest respec¬ tively two perforated horizontal annular discs g s connected together by a central vertical truncated conical chimney h perforated with holes around its circum¬ ference on the portion situated between the two discs g s and prolonged toward the top above the perforated disc g which receives the sulphur or material to be [Price Sc/.]
