Application filed April 22-, 1903. Serial No. 153,752. (No model.)
To all whom, it may concern.-
Be it known that LWILLIAM HULSE MILLS- IAUGH, a citizen of theUuited States, residing ing Apparatus; and I do hereby declare the apparatus embodying my invention.
followingto be a full, clear,'and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to apparatus for mixing and spraying differentliquids; and its principalobject is to provide a simple and highly-efficient apparatus for such purpose in which the admixture or commingling of the different fluids will be effected thoroughly and in precisely the desired proportions. Such an apparatus is particularly useful in oil-spraying outfits in which kerosene or other oil is mixed and sprayed with water or other liquid for insecticide, disinfectant, or other purposes where it is essential that the liquids be commingled uniformly and in the desired proportions for the purpose intended; but the invention is of course not limited to any specific application.
The invention will hereinafter be first fully described with reference to the accompanying drawings, which form a part of this specification, and then pointed out in the claims following the description.
In said drawings, wherein corresponding parts in the different figures are indicated by like reference-symbols, Figure 1 represents in elevation a liquid mixing and spraying Fig. 2 is a detail longitudinal sectional view of the connection or junction of the discharge or outlet hose or pipes from the liquid-tanks of said apparatus. Fig. 3 is a detail plan view of the apertured plate in said junction through which theliquids pass audby means of whichthe proportions of the different liquids in the discharged admixture are regulated. Fig. i is an enlarged detail elevation, partly in section, of a different form of connection or junction for said discharge hose or pipes; and Fig. 5 is a detail plan view of one of the apertured plates in said latter junction.
The apparatus herein illustrated comprises, in the main, a pair of air-tight tanks or receptacles for the difierent liquids, an airpump having free connection with both tanks at their upper parts, so as to exert equal pressures on the two liquids, outlet hose or pipes from saidtankshavingajunction or connection to a common discharge-pipe, means for regulating the flow of eachliquid through said junction, and a spray-nozzle connected to said outlet pipe and through which the mixed liquids discharge.
Referring to Fig. l, the letters A and B dos-- ignate said tanks, the former of which may contain oil and the latter water. These tanks are connected at their upper parts by a pipe 0, which is joined intermediate said tanks to a hose or pipe D,1cading from the air-pump E. The pipe 0 may be provided with controlling-valves, one at each side of its junction with the pipe D, so as to out off the airpressure from either tank when desired. The hose or pipe D may be provided with a suitable check-valve d to permit the flow of air from the air-pum p, but to prevent backward pressure thereof. The letter F refers to the outlet hose or pipes, each of which may also be provided with a controlling valve or valves for cutting off the flow of liquid at will. Any suitable strainers may be placed within the tanks for straining and freeing the liquids of foreign substances before they fiow into said hose or pipes. The hose F are shown con nected to pipes G, which have a junction or union with a discharge-pipe H, which latter may be provided with a spray-nozzle J. The juuctiou'of said pipes G may be effected by any suitable means. As shown in Figs. 1 and 2, said pipes G are screwed into a plug K,
-haviug bores therethrough registering with date L fits within the recess of the enlarged part h of pipe ll and is clamped between the inner liat face of the latter and the plug K. Said plate has liquid-apertu res l therein registering with the liquid passages or bores in the plug and of suitable sizes to allow the passage of the desired proportion of each liquid. The sizes of the apertures may be determined by tests or by any of the ordinary scientific methods. Tlhe plate L, as shown in Fig. 3, has three apertures therein. The
smaller ones, 1, register with the bores in the plug It, while the larger one, l, fits over a pin or stud 70, set in said plug, as'indicated by dotted lines in Fig. 2, so as to insure registration of the apertures Z with said bores. Dfiercnt plates with suitably -SiZ9 d apertures ttl j1LtS8UOIflObDalH'Itlgllfgfilggll pro por tionsbf thYalliquids' inf the admixture.
For example, assn ming that theta'nk'sAand B contain liquids having substantially the same fluidity or flow properties, it fifty per cent. of each liquid be desired in the admixture the holes in the plate should be of the same size. If a mixture of twenty per cent.
of oil and eighty per cent. of water be desired, a plate should be employed having apertures approximately one-sixteenth and one eighth inches. For other proportions other plates should be substituted having apertures of proper sizes to allow the desired llow of liquids under the same pressure.
\Vhere tho tauks'contain liquids one of which is more or less viscous or less fluid than the other, special plates are required having apertu res adapted to allow the passage of the desired proportions of said liquids, the sizes of said apertures being of course determined by proper tests or calculations. For any desired admixture, the proper plate being used,
it is obvious that precisely the required proportions of the liquids will be obtained, since the pressures on both liquids in the tanks are equal, and the rate of flow depends only on the sizes of the openings. Whatever pressure may be exerted on the liquids in the tanks, or however such pressure may vary,
the proportional rate of tlow will remain constant, since the pressures in both tanks are always equal. By reason of the junction of the outlet-pipes the different liquids coming oppositely together under pressure are thoroughly com mingled and a perfect mechanical mixture in desired proportions is thus obtained.
In Fig. 4 a different form of junction or connection for the outlet-pipes is illustrated. In this figure the hose F are shown connected to short flanged thi'mbles or pipe-sections M, which are joined bysuitable unions N to the branches 0 of a discharge-pipe P, which latter is shown having a socket between its branches, in which fits a handle Q. This handle may be of any suitable length, and by means thereof the discharge-pipe or spraynozzle thereon can be pushed up into the foliage or trees to be sprayed. Between the flanged end of each thimble M and end of each branch 0 is clamped asnitable plate R, having an aperture of proper size to allow the desired rate or proportion of flow.
The invention is susceptible of various modifications in details of construction and arrangement and is not limited to the particular embodiment herein illustrated. It may also be embodied in an apparatus having any suitable number of tanks containing different liquids desired to be commingled. tVhere such a plurality of tanks are employed, any one or more may be out OK from operation by closing the valves of the air-inlet and liquid-outlet pipes thereof.
