Application filed March 13, 1900. Serial No. 8,483. (No model.)

To al?, whom t may concern:

Beit known that I, JOHN J. COUGHLIN, a citizen of the United States, and a resident of Bradford, in thecounty of Miami and State of Ohio, have invented a new and Improved Spraying Apparatus, of which the following is a full, clear, and exact description.

This invention is an apparatus for spraying liquids, and it is adapted especially for spraying trees, shrubbery, and the like, to which end it comprises a liquid-reservoir and an airreservoir, the two being separable and provided with means for removably engaging them, so that they may be carried about on a cart, the air-reservoir having a pump and being in communication with the liquid-reservoir by means of a iiexible tube.

This specification is the disclosure of one form of the invention, While the claims dene the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a side View of the invention. Fig. 2 is a sectional side view thereof, and Fig. 3 is a detail View of the safety-valve which I employ.

The air-reservoirct, in which the air is stored under pressure, is provided with a tongue 4, attached to one side thereof, and this tongue is slidably engaged with inwardlyturned lianges 5, fastened side by side to the liquidreservoir l). The upper end of the tongue 4 is fastened to the reservoir d, so that by moving the reservoir a upward relatively to the reservoir b the two may be disengaged. A handle 6 is attached to the reservoir l), and when the reservoir b is carried by this handle the other reservoir will also be supported. Owing to the fact that the reservoir l) is filled or partly filled with liquid, the whole device may be 'carried horizontally, and the reservoir a, having no weighty substance therein, will not tend to tilt the reservoir b.

A pump-cylinder 7 is mounted eentrallyin the air-reservoir a and provided at its loweil en d with a downwardlyopening valve 8, pressed to its seat by a spring 9, carried in the bottom of the pump-cylinder, which passes through the bottom of the reservoir a. The

lower end of the cylinder 7, below the valve 8, a tube l1 passes. This tube is situated within the air-reservoir and extends upward to a valve-casing 3l, mounted on the reser- Voir and communicating with the interior thereof. In the valve-casing 31 a needlevalve 17 works, such valve commanding the pipe l1. The air from the cylinder 7 passes by the valve S and through the pipe ll to the casing 31, from which it passes into the reservoir a through an opening Sll. By the parts 1l, 3l, and 17 leakage or air from the pump is prevented.

A flexible pipe 18 leads from the reservoir a to the reservoir b, the pipe being connected with the tops of the respective reservoirs and commanded by a cock 19. The pipe 1S has rigid extensions 18a projected, respectively, into the reservoirs d and b in close proximity to the bottoms thereof. A metallic dischargepipe 2O is located in the liquid-reservoir l? and has its receiving or lower end directly adjacent to the bottom of the same, the pipe passing upward through the top and having a cock 21 commanding the pipe. A flexible spray-pipe 22 with a rose or nozzle of any desired form is connected with the pipe 20.

In the operation of the apparatus the liquid is placed within the reservoir b upon removing the filling-cap 29,'and the valve 17 is operated to uncover the pipe 1l. Then the pump is operated to store air at a proper pressure Within the reservoir a. The valve 17 should now be shut. The valves 19 and 2l should then be opened, and the pressure of air inthe reservoir a will pass to the reservoir l) and act on the water therein to throw the same out through the pipes 20 and 22. If desired, a safety-valve, as shown in Figs. l and 3, may be provided for the reservoir a. This valve is here shown as consisting of a casing 23,


provided with a cap 24, in which is mounted to slide a valve-stem 25, carrying a valve-26, having a seat at the bottom of the casing 23. A spring 27 presses the valve yieldingly in closed position, and when the air-pressure within the reservoir a becomes so great aste force the valve 26 upward the excess of air may pass off through an orice 2S in the casing 23. A pressure-indicator 30 may also be provided for the reservoir d, if desired. By extending the pipe 18 down into the reservoir b the spraying solution therein is kept agitated and in proper conditi-011 for use.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A spraying apparatus, comprising a liquid-,reservoir and an air-reservoir, a flexible connection between the two, whereby to conduct the air from the air-reservoir to the liquid-reservoir, a handle on the liquid-reservoir, a tongue attached at its upper end to the air-reservoir, and a keeper carried by the liquid-reservoir and having the tongue slidably engaged therewith.

2. A spraying apparatus, comprising a liquid-reservoir, an air-reservoir separate therefrom, means for removably connecting the two reservoirs with each other, by which to carry Gear/'ee the one on and alongside of the. other, and a fiexibletube passing from one reservoir to the other to establish communication between the two.

3. A spraying apparatus, comprising a liquid-reservoir and an air-reservoir, m'eansfor removably connecting the two with each other, a {i'exible pipe extending between them to lead the air from the air-reservoir to the Waterreservoir,a liquid-discharge pipe leading from the liquid-reservoir,and an air-pum p mounted in the air-reservoir.

4E. A spraying apparatus having an air-reservoir, a liquid-reservoir, a pump carried in the air-reservoir, a pipe situated within the air-reservoir and leading the air from the pump, a valve-c`asi`ngcarried on an outer wall of the air-reservoir and communicating with the interior thereof, the said pipe com-municating with the valve-casing, and a valve commanding suchcommunication.

In testimony whereof I have .signed my name to this specification in the presence of two subscribing witnesses.
