Abstract
Abstract A fogging attachment for an internal combustion engine in which a container of vaporizable insecticide solution may be coupled through two conduits to the muffler of the engine by a fitting which has a cylindrical stem adapted to extend through a cylindrical opening in the wall of the muffler and to be secured to the muffler by a deformable sleeve which is deformed to engage the inner wall of the sleeve, said stem having a cylindrical opening divided by a divider plate into two semicylindrical openings, each of which communicates with one of the two conduits.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
243 words
In an insecticide fogging attachment for an internal combustion engine having an exhaust gas muffler, a container of a vaporizable insecticide solution, two conduits of circular cross section for extending from said container to the muffler of the internal combustion engine, a first fitting for coupling said conduits to the bottom of said container, said fitting having means for coupling one of said conduits to the interior of said container with one end of said conduit adjacent the bottom of the container for delivery of insecticide from said container to the muffler and for coupling the other of the conduits to the interior of said container with one end of said conduit adjacent the top of the container for conveying gas from the muffler to the top of said container to replace the insecticide drawn therefrom, and a second fitting remote from said first fitting for coupling the other ends of said two conduits to the muffler, said fitting having at one end two circular cylindrical passages of substantially the same diameter as the external diaMeter of said conduits and in which the other ends of said conduits are secured, said second fitting further having at its opposite end a cylindrical stem adapted to extend through a circular opening in said muffler and to be secured thereto, said stem having two semicylindrical passages in said stem, each of which partially overlies and is connected with a different one of said two cylindrical passages.
Claim 2
Dependent Claim
243 words
In an insecticide fogging attachment for an internal combustion engine having an exhaust gas muffler, a container of a vaporizable insecticide solution, two conduits of circular cross section for extending from said container to the muffler of the internal combustion engine, a first fitting for coupling said conduits to the bottom of said container, said fitting having means for coupling one of said conduits to the interior of said container with one end of said conduit adjacent the bottom of the container for delivery of insecticide from said container to the muffler and for coupling the other of the conduits to the interior of said container with one end of said conduit adjacent the top of the container for conveying gas from the muffler to the top of said container to replace the insecticide drawn therefrom, and a second fitting remote from said first fitting for coupling the other ends of said two conduits to the muffler, said fitting having at one end two circular cylindrical passages of substantially the same diameter as the external diaMeter of said conduits and in which the other ends of said conduits are secured, said second fitting further having at its opposite end a cylindrical stem adapted to extend through a circular opening in said muffler and to be secured thereto, said stem having two semicylindrical passages in said stem, each of which partially overlies and is connected with a different one of said two cylindrical passages.
Claim 3
Dependent Claim
63 words
The fogging attachment of claim 1 in which a sleeve of relatively soft metal surrounds and is threadedly engaged with and abuts a shoulder on the stem of said first fitting so that when said first fitting is inserted through a cylindrical opening and said sleeve and stem are relatively rotated, said sleeve is compressed to engage the inner wall of said muffler.
Claim 4
Dependent Claim
39 words
The fogging attachment of claim 2 in which both said stem and said sleeve of relatively soft metal have bolt heads which are adapted to engage each other and which facilitate relative rotation of said sleeve and said stem.
Claim 5
Dependent Claim
42 words
The fogging attachment of claim 1 in which said stem has a single cylindrical passage with a divider plate extending centrally therethrough and being disposed at its inner end between the inner ends of said conduits to form said two semicylindrical passages.
Claim 6
Dependent Claim
25 words
The fogging attachment of claim 4 in which said divider plate has its inner end engaging and wedged between the inner ends of said conduits.
Claim 7
Dependent Claim
50 words
The fogging attachment of claim 4 in which said divider plate has an effective width slightly in excess of the inner diameter of said single cylindrical passage so that said divider plate tightly engages the wall of said cylindrical passage and acts to divide the same into said semicylindrical passages.
