UNITED STATES PATENT OFFICE.

J'OHN DESMOND, OF CHICAGO, ILLINOIS, ASSIGNOR TO ARTIZAN BRASS COMPANY, OF

' CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

' LIQUID-DISPENSER.

To all whom it may concern:

Be it known that I, JOHN DEsMoNn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Liquid-Dispensers, of which thefollowing is a specification.

My invention relates to improvements 111 liquid dispensers. It has particular reference to devices of this character wherein liquid is held within a receptacle or reservoir under pneumatic pressure and projected therefrom in=a solid stream, or in an atomized spray as its use may vary.

One of the objects of my invention is t.o provide a device. wherein-a spraying liqu d, such as an insecticide, ora cleaning liquid, such as gasolene or the like, or a very finely divided powder may be contained under pneumatic pressure and sprayed or projected against or on objects in desirable quantities and at convenient times.

Other and further objects of my invention will become apparent to persons skilled in the art from the description and drawings,

wherein- Figure 1 is'a longitudinal section of the device; and Fig. 2 is a similar view of a fragment of the device, showing a spraying nozzle inserted therein, instead of the solid, stream nozzle shown in Fig. 1.

In both views the same reference characters refer always to like parts.

The reservoir or cylinder, 5, may be made of a suitablemetal, such asbrass or the like,

and is preferably provided with bumped ends. p j

A handle, 8, is secured to an end of the casing, as shown,,by means of which the evice may be manipulated. A nozzle, 9..

for projecting a solid stream, shown in-Fig. 1, is screwed into a threaded opening, '10. It is provided with'a clearfront opening and with a relatively long bore, as shown at 11, for guiding'and retaining'thevalve stem, 12. At the inner end of thebore, 11, a valve seat, 13, is provided for rece tion' of .the needle valve, 14, on the end of t e valve stem 12. Lateral openings, 1515, admit liquidor powder, as the'case may be, to the nozzle proper. A gland, 16, is secured to the other i packing thevalve reciprocation and to" render the casing "substantially pressure-'- end of the casing-for stem to permit its easy tight. Packing, 17, as usual in suchdevices,

Specification of Letters Patent. Patented Del}. 10, 1912., Application filed January 10, 1910. Serial is employed for this purpose. is secured to the valve stem, 12, 19, against which the open spring, 20, abuts for normally the valve closed, as clearly shown. The outer end ofthe valve stem, 12, carries a handle which is limited in its reciprocating movement by the. handle 8. When the handle, 21, is moved its full extent, or until it comes into actual contact with handleS, it has not been moved sufficiently to withdraw the valve, nozzle, 9, and thus the valve cannot be displaced with reference to its seat. A filling cup, 22, is screw-threaded'and extends into the cylinder about one third of' the way across the diameter thereof so as to leave an unoccupied space above its lower edge when filling the .device with materialto be 'applied in the manner described." A stopper, 23, is screw-threaded into said cup and when inserted therein tightly closes the same. An air valve, 24, similar to valves of this character used on the cylinder, therein. The use and operation of-the device is as as by a pin, compression 5, and controls an air opening with, the material to be dispensed, it should be held in the position shown in the drawing, and the liquid,for other material poured in through the cup, 22. The reservoircannotbe filled beyond the lower'edgeof the cup, leavingan unfilled space between the lower edge of the'cup andthe top of the reservoir. The device is then connected to an air pump, vthe valve, 24, and air under'pressure is thereby admitted into thefotherwise unoccupied space Within the reservoir. The air may be compressed to any pract'cable limit, say inpractice anywhere from 2 square inch, more or less. The instrument is now ready for use. If it has been charged wit-h gasolene or the like, and compressed air, itshould beheld in the position shown a downward directionand .themha'ndlef2l, compressed or drawnitowardthe handle 8.- he valve is thusv opened andthel liquid constream, against a used for'other-purposes. When the nozzle maintaining tents'will be violently'pro ect'ed, in a solid A collar, 18,

1% from the bore, 11, of the 'pneumatictires, is secured to follows: When the reservoir is to be filled or compressed air reservoir at to pounds per or with its nozzle end pointing slightly in surface to be cleaned, such for-1nstance as the oily surfaceof an enginefi H or the like, or the liquid in astream may b64 9', shown in Fig. 2, is substitutd for the nozzle 9, the liquid will be atomized or sprayed. The device may be charged with a suitable insecticide, such as the Bordeaux mixture, and the otherwise unoccupied space may be filled with air under pressure from a source of air supply. The air may be passed into the cylinder through the nozzle, 9 or 9, when the-valve thereof is retracted by pressure applied to the handle, 21, in which event the check valve, 24, will not be necessary. The device thus loaded may be taken to the tops of high trees, from which position limbs and branches, inaccessible by the usual spraying devices with hose attached, may be convenientlyand thoroughly suitable closures, in combination with a nozzle for said outlet providing a small bore, a valve. seat at the inner end thereof, and a cylindrical valve-stem-guiding portion extending inwardly from said valve seat, a valve stem extending through the opposite end of. said cylinder, at its inner end shaped to coact with said valve seat and at its outer end having a portion extended" laterally to provide a handle movable to move the stem, and a stationary handle mounted on said cylinder, by which said cylinder may be pointed in any desired direction, said handle for the valve stem being spaced from the stationary handle a distance less than the length of said cylindrical guiding portion of the nozzle, whereby said nozzle bore may be opened by grasping and drawing together said handles, said stem being in all positions guided at its inner end so that lateral pressure may be conveniently applied thereto, adjacent the handle, to aid in manipulation of said cylinder by suitable gripping of said handles.

In testimony whereof I hereunto set my hand. in the presence of two witnesses.
