APPARATUS FOR DESTROYING ANIMAL LIFE.
Application flled J'anuary 8, 1921. Serial No. 435,892.
T 0 all whom it may concern:
l 3e it known that I, DAVID B. MACKIE, a citizen of the United States, residing at Los Angeles, county of Los Angeles, and State of California, have invented a new and useful Apparatus for Destroying Animal Life, of which the following is a specification! My invention relates to apparatus used for the destruction of insect life, bacteria or the like in various fabrics, food products and other merchandise. It is particularly applicable to the treating of food stuffs and to the treating 0f hides, fabrics and plants of various kinds.
The principal object of the invention is to provide apparatus for destroying insects or bacteria in all such merchandise without injuring the merchandise or without leaving it in such a condition as to make it necessary to afterwards dry or otherwise treat the merchandise.
Further objects and advantages will be made evident hereinafter. ,7
Referring to the drawings which are for illustrative purposes only,
Fig. 1 is a view of an apparatus with the 3 door closed.
Fig. 2 is a similar view with the door open showing a case of merchandise therein, a portion of this case being broken away to show the internal arrangement.
Fig. 3 is a side view of the apparatus shown in Fig. 1 and, v
Fig. 4 is a detail of a small portion of the apparatus showing the locking action.
In the embodiment of the invention shown, a shell 11 is provided, this shell being'supported on feet 12 from a floor 13. The shell 11 is formed of sheet metal welded or riveted so that it will withstand consider" able pressure, this shell being closed at one end as shown at 14 and being open at the other end. Surrounding the opening is a flange 15 forming an integral part of the shell. Formed on the shell are hinge bosses 20 in which an axle or pin 21 is secured. Turning on the axle 21 are arms 22, forming a support which carries a bolt 23 which passes through a cover 24 at its center, and about which this cover may turn. The cover 24 is provided with lugs 25 which project outwardly beyond the edge thereof, and which may be swung into engagement with lugs 26 formed on the flange 15. The lugs 25 and 26 have the form shown in Fig. 4 being wedge shaped so that as the cover is turned in the 64 with the interior ofthe container.
The interior of the receptacle 62 communi-' cates through a pipe 63 controlled by a Vall municates with the interior of the .container and a gauge 67 is so connected that it will indicate the vacuum in the container. The method of operation is as follows:
The merchandise to be treated, such for example as the merchandise in the cartons 53 is placed. inside the shell 11 and the door 24 is closed and locked in gas tight relationship with the shell of the flange 15. ,The valves 64 and 66 are closed. The valve 61 is opened and the pump 60 is started exhausting the air from the interior of the shell 11 to a certain degree. The packing case 51 and the cartons 53 not being air tight, theair is also exhausted from the interior thereof to the same degree. When the exhaustion has reached the desired point as indicated by the gauge 67, the valve 61 is closed and the valve 63 is opened. This allows gas to be taken from the top of the receptacle 62,
2 morass this gas being either replaced with air admitted through a pipe controlled by a valve 71 or being spontaneously generated in the receptacle due to the reduction in pressure.
I find that carbon disulphide is an excellent lethal agent for most purposes. When carbon disulphide is used, it is placed in the liquid form in the receptacle 62 and the valve 71 is opened a small amount so that air is drawn through the pipe 70, immersed in the liquid bubbling therethrough and becoming impregnated with carbon disulphide vapor. This mixture of air and vapor passes through the pipe 63 into the interior of the shell 11, being forced into the interior of the packing case 51 and the cartons 53 and being further forced into all the interstices of the merchandise. The merchandise is then allowed to stand with the carbon disulphide vapor permeating it for sixty minutes or in some cases longer, and the valve 64 is again closed. The pump 60 is started and the valve 61 is openedf A second exhaustion of the interior of the cylinder 11 then takes place, the carbon'disulphide vapor being drawn out by means of the pump 60 from the interior of t-heacartons 53 and from the crevices in the merchandise which it is desired to treat. Vi/ hen this exhaustion has reached any desired degree, the valve 66 is opened and air is allowed to enter the container. If it is desired to effect a very complete removalof the carbon disulphide, the valve 66 may then be closed and a second exhaustion maytake place. These exhaustions may-be repeated to any desired degree.
