METHOD AND AIPIAIRATUS FOR DISPEBSING TOXIC AND OTHER IRRITANT SUBSTANCES.
Originalli'o. 1,541,103, dated June 9, 1925, Serial-No. 713,599, filed May 1924. Application for reissue flied September 2, 1926. Serial No. 133,288.
This invention relates to the dispersion of toxic and irritant substances without sub stantial chemical decomposition.
Among the objects of. .,this invention 1s to i provide a process and apparatus for dispersing toxic and irritant substances, for ex ample, diphenylaminechlorarsine and chlor 5 decomposition of a substantial portion of the evolved irritant or toxic material and whereby overheating of the toxic is practically reduced to a minimum. A further object of this invention ls'to I provide a portable apparatus serving .as a candle wherein avaporizable body of irrisame, the hot gases acting as avehicle for the vaporized irritant. Preferably, the
i evolved combustion gases are caused to pass over a body of the toxic orirritant in such manner as to avoid overheating of the toxic or irritant and thus prevent raising thebody ,of such material or the evolved products therefrom to a temperature which would result in a substantial decomposition.
Other,.further and more specific objects of the invention will become readily apparent to persons skilled in the'art from a consideration of the following description when taken in conjunction with the drawing, wherein a specific form of a device for carrying out" my invention is shown partly in elevation and partly in section, a. portion of the device being broken away to illustrate the interior construction thereof.
This apparatus consists of a can having a lower compartment (1) bolted or otherwise fastened to the upper compartment (2) suitablepacking material (3), for examp e asbestos'paper, bein provided to make a tight connection. Att e bottom-of compartment (1) is laced a suitable fuel mixture 4) upon w i'ch is placed amatch composition (5).. This match composition is set ofi by pulling. the rod (6) which brings the scratcher composition (7) in contact with the match composition (5), the latter being sensitive to frlctlonal engagement with the scratcher composition (7). When this match compositlon burns it ignites the fuel mixture t) and the products of combustion through the stack. (8). I The stack (8) is connected to the plate forming the base of the upper compartpass out ment (2). Upon this plate .(9) is placed thetoxic or irritant (10). As the products of combustion of the fuel (4) leave thestack (8) they pass over the surface of the toxic or irritant (10), being deflected by the .baflie plate (11) so as to travel over practically the entire surface of the toxic or irritant material. These combustion gases heat the toxic or irritant and cause same to volatilize and become entrained in the combustion gases and pass out therewith through the conduit (12) leading to the opening (13).
at the' top of the can. tant is subjected to hot gases to vaporlze the The portion (14) of the baflie plate (11), whlch is directly over the mouth of the stack (8) from which the combustion gases issue, is preferably re-enforced by plate (15) and asbestos material (16) is inserted between plates (14) and (15). This portion of the plate (11) is also-near the exit opening (13) of the can and it is desirableto-prevent as much as possible the'heating of these gases as they issue from the can. By providing this asbestos (16), excessive heating-by the combustion gases of theplate (11) at this point'is eliminated to a large extent, if not completely avoided.
In order to facilit'atethe' operation of the rod (6) carrying the scratcher composition (7),- one-end of rod (6) is provided with a handle (17). The match composition (5) is kept 1n position by means of a zinc strip (18) and the anchor wires (19) embedded inthe fuel ('45).
The fuel (4) may be a suitable explosive such as black powder;nitrocellulose, a mixture of nitrocellulose and nitroglycerine, a mixture of charcoal and NHJTO or a mixtureofcharcoal and NaNO I A suitable -match composit'on consists of KQIO v (5 parts) and black antimony sul' phlde (2 parts) bound together i 1 Clplart). v e scratcher composition may consist of by dextrine red phosphorous (6 parts) and fine sand 83 use chloracetotoluone, capsaicin or diphenylchlorarsine.
As is known, the halogen derivatives of acetophenone are capable of producing irritation and lac'h-rymation at concentrations below .01 milligrams per liter in three minutes when persons are exposed thereto.
The device is operated by drawing the scratcher over the match composition, causing the latter to ignite and fire the fuel (4). The combustion gases of this fuel pass over the surface of the body of irritant, thereby heating and volatilizing the irritant. This exchange of heat raises the irritant to a temperature permitting the products of com bustion, as they pass over the surface of the irritant, to carry off a considerable amount of the irritant vapors. The combustion gases are also partially cooled by this exchange of heat, thus preventing objectionable or serious decomposition of the irritant gases. The net effect of this lengthy passage of the combustion gases over the surface of the irritant is to accomplish the distillation of the irritant at a much lower erature than would occur by direct heating and. thereby avoiding exposure of the-evolved irritant to temperatures promoting decomposition or chemical reaction rendering the volatilized material unfit for the purposes desired. v
In my reissue Patent 16,495, there is disclosed and claimed a specific form of my broad invention in which the fuel and the irritant are in contact with one another and are preferably intimately distributed.
The present invention is not limited to the specific details set forth in the foregoing examples which should be construed as illustrative and not by way of limitation, and in view of the numerous modifications which may be effected therein without departing from the spirit and scope of this invention, it is desired that .onlysuch limitations be posed as are indicated in the appended claims.
