(Granted un derthe act ofjMarch made under the act of l '30, 1928, and the inventionherein described, if patented, may be manufactured 'anduse'dby or for the Government ofjthe United States of America for governmental purposes without the payment to us of any royalty thereon.
We hereby dedicate ,theinvention herein described to the'free use'of'the" people in the territory of the United States'tdtake effecton the granting of a patent to us.
This invention relates to devices for dispersing insecticides, and has among its objects the provision of a device of this kind which is sirnple to manufacture and which may be used rapidly to disperse a controlled amount of insecticide throughout a large'reg'lon, giving a flnely divided dispersion of the material and with uniform coverage thereof. v
i Inge'neral, according to the inventiommeans .isfprovided'for releasing" a relatively large volume of ga'sfrom a high-pressure'source through a tube, thus to give a'high velocity of as fl w.-
I A container is provided for holding a quantity of the insecticide material to be dispersed, and part of the gas flowing throughthe tube is deflected into the container above the insecticide material therein, thus to create pressure on it. A relatively large opening leads from the container from near its bottom and empties into the tube at a point beyond that from which the gas is deflected into the container. The gas pressure developed in the container quickly forces the insecticide material, which is free flOWiIlg (a liquid or powder), through the opening into the stream of gas passing through the tube, and the material in finely divided form is uniformly dispersed with the stream of discharged gas throughout a relatively large region.
For a detail description of the invention, reference is made to the accompanying drawing, in
which Figure 1 is an elevation of one form of the disperser designed primarily for dispersing a liquid;
Figure 2 is 'a central section taken in the plane of the paper showing a part of the disperser of Figure 1; 1
Figure 3 is a partial section on the line 3-3 of Figure 2;
Figure 4 is a partial elevation of a modified form of the disperser showing two containers and designed especially for dispersing a free-flowing powder; and V Figure 5 is a detail, partially in section, showing one of the containers of Figure 4.

high-pressure gas,
we, as In the drawing, ll representsa cylinder of small cylinder of compressed "carbon dioxide 101' ofdichlorodifluoromethane (flre extinguisher type) being satisfactory for the purpose. The cylinder is provided with a handle I! and triggervalve' I I3-,for release of the gas in a well-knownmanner.v 7
The dispersing device isprovided with a rigid tube through which the released gas passes, this tube being connectedto the outlet from the cylinder II by means of a fflexible tube E6. The free end of tube 15 may be provided with an angled portion such as a 45 elbow ",if desired.
Container is provided for holding the insecticide material. shown, this container is in the form'o'fiapipenipple 2! closed at the bottom with a cap 22' and at the top. with a cap 23; Cap 23is welded directly to the tube 15, as I illustrated.
In use, a measured amount of a liquid insecticide material is placed in container 20. This may be accomplished by merely demounting the nipple 2| from cap 23. With the insecticide material in place, operation of trigger valve is ejects a large volume of high velocity gas through tube l5 while simultaneously a high pressure of gas is obtained in thecontainer on the liquid therein due to deflection of a portion of the gas by the deflector 21. This results in a rapid expelling of the insecticide material from the container through pipe 3! and into the gas stream flowing through tube [5. With a small size device, 2! may be a 1" by 3 nipple, in which case one-half ounce of liquid may be quickly dispersed with one or two short blasts of gas release.
The form shown in Figures 4 and 5 is generally quite similar to that previously described. In this form;a.,tube 35" leads fromftheigas pressure cylinder (not shown) and communicates with two divergent tubes 36 and 31, each of which is provided with an upright closed container such-as beyond the fixed tab, whereby as gas is released through the tube a portion of it is deflected into the container to create pressure on the dust therein and force it through heopening into the stream ofgg'as passingtlthrough gthe itube.
2. An insecticide disperser comprising a tube, means for releasing gas from a high-pressure osource through the tube, an upright closed conshown at 38 attached at its bottomportionto the tube, thus to provide a double disperser. The containers are similar, and fonly'onewillebe described in detail. 7
The container 38 is provi'dedewith a nipple closed at its top with cap 40 and at its lower end with cap 4|, in this form the lower nipple 4i being welded to tube 31. Aperture 42 and opening 43 correspond to aperture 24 and opening'30; -respectively, in Figure 2. In the-present form a tamer-for holding a quantity 7.
of free-flowing insecticide dust attached at its bottom portion to the ;;tube, .an
(aperture having a pipe communicatin'g' therewith and projecting upwardly into thefcontainer,fterminating near the upper end thereof establishing communication between the :tube and container and a deflector positioned in the tube for deflecting a portion of the gas from the tube through the aperture and pipe and into the container and an ,opening for passage of pipe 44 is mounted in aperturll andiextends upwardly into the container terminating near its upper end, deflectorf 45being provided for the purpose previously described-{in reference to ,defleQtor containerand empties into tuber3l.
musing-this iormof thefdev ice, the cover cap '40 is removed; a'measured quantity ofinsecticide dust is placedin the container and the cover is replaced. Operation of-the'trigger' valve results in rapid expulsion ofthef dust from the container in a mannersimilar to that'previously described in "referencetd thrfirst-mentionedform.
