Description

Nov. 2, 1937. A. A. MARYOTT FOUNTAIN SPRAYING DEVICE Fild Sept. 28. 1956 Patented Nov. 2, 1937 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to fountain spraying devices, and has more particular reference to an improved device of this kind embodying a novel form of dispensing tank adapted to constitute a 5 reservoir for the liquid to be sprayed and from which such liquid to be sprayed may be efiectively forced or dispensed by water under pressure in such a manner that the liquid to be sprayed will not be diluted by such water under 19 pressure.

A more specific object of the present invention is to provide a spraying device of the above kind wherein the liquid dispensing tank is divided into two non-communicating compartments by means of a flexible diaphragm, wherein such tank is provided with a port communicating with each compartment, and wherein a hose conveying water under pressure may be connected with either port for supplying the water under 20 pressure to either compartment and actuating the diaphragm to discharge liquid to be sprayed from the other compartment.

Other objects are to provide a fountain spraying device having a dispensing tank of the above character which is simple in construction, economical to produce, efficient in operation, and convenient and easy to use.

Still further objects of the present invention will become apparent from the following description when considered in connection with the accompanying drawing, in which:-

Figure 1 is an elevational view of a spraying device embodying a dispensing tank constructed in accordance with the present invention;

Figure 2 is an enlarged plan view of one section of the tank shown in Figure 1 and looking interior thereof, the tank section being partly broken away; and Figure 3 is an enlarged transverse section on line 3-3 of Figure 1.

Referring in detail to the drawing, while the present inventionis adapted for general use in the dispensing of liquids, itis particularly designed for and useful in spraying trees and other vegetation. As shown, the device includes a dispensing tank of elongated and preferably cylindrical form, and composedof two

longitudinal half sections

5 and 6 bolted or otherwise secured 50 together as at 1. Clamped at its marginbetween the

half sections

5 and 6 of the tank so as to form a water-tight joint between said tank sections, is a flexible diaphragm 8 which divides the interior of the tank into two non-communicating 55 compartments or chambers. Each tank section is provided with a port surrounded by a projecting nipple 9, thereby affording communication with each of the tank chambers. The nipples 9 are of similar form so that the end of a hose l0 may be coupled with either nipple for supplying water under pressure to either chamber of thetank at one side of the diaphragm 8 for operating such diaphragm and forcing the spraying liquid from the other cham ber of the tank at the opposite side of said diaphragm 8 and through the other nipple 9. A suitable outlet hose H is also provided, adapted to be coupled at one end with either nipple 9 and provided at its other end with a suitable spray nozzle i2.

It will be noted that the diaphragm 8 is of such a character or form that it may be forced into engagement with the surface of either tank section for completely discharging spraying liquid from either chamber of the tank. Also, the nipples 9 are preferably provided in the

sections

5 and 6 intermediate the ends of the latter, and in order to insure against clogging the nipples 9, as well as to insure complete discharge of spray liquid from either chamber of the tank, an inwardly convexed screen is arranged and suitably secured within each tank section so as to extend longitudinally and from end to end thereof in a plane intersecting the nipple 9 of such section. Each screen l3 thus prevents contact of the diaphragm 8 with the associated tank section throughout the length of the latter at a zone coincident with the nipple 9 of said tank section, thereby permitting substantially complete discharge of the spray liquid from such tank section. It will particularly be apparent that the screen B3 of each tank section will prevent the diaphragm 8 from closing the nipple 9 of such section. In order to avoid distortion of the screen l3 to an objectionable extent and to substantially maintain the inwardly convexed form of each screen, a rod [4 extends longitudinally of each tank section beneath the center of each screen I3 or between the central portion of each screen and the opposed portion of the associated tank section.

In use, the liquid to be sprayed is introduced into the tank so as to substantially fill the latter at one side of the diaphragm 8, whereupon the outlet hose i l is coupled to the nipple 9 at this side of the diaphragm and the water supply hose [0 is coupled to the remaining nipple 9. When water under pressure is allowed to flow into the tank through the hose ill, the diaphragm 8 will be forced by the pressure of this water in a direction away from the nipple 9 to which the hose III is coupled, thereby forcing the liquid to be sprayed from the tank through the other nipple to which the outlet hose i l is coupled. When the spray liduid has been completely dispensed from the tank, the tank will have become filled with water at the other side of the diaphragm, and another charge of spray liquid may be had by simply adding the desired material to this water. The hose l0 and outlet hose ii are then reversed so that the hose I0 is coupled to the nipple 9 to which the outlet hose H was initially coupled and so that the outlet hose i l is coupled to the nipple 9 to which the water supply hose H) was initially coupled. The new or second charge of spray liquid may then be similarly dispensed from the tank when water under pressure is supplied by the hose I 6. This operation may be repeated as often as desired, the water used to dispense the spray liquid being utilized in forming the next charge of spray liquid.

From the foregoing description, it will be seen that I have provided an eihcient means for carrying out the stated objects of the invention.

What I claim as new is:-

1. In a fountain spraying device of the character described, a dispensing tank of elongated form adapted to constitute a reservoir for the liquid for spraying, a flexible diaphragm dividing the interior of said tank into two non-communicating chambers, outlet nipples for said tank at opposite sides of said diaphragm, said nipples being of similar form to facilitate connection of either of the same with a source of supply of water under pressure, said diaphragm being of a character to be actuated by said water under pressure when introduced at one side of said diaphragm to substantially completely discharge a liquid to be sprayed from said tank at the opposite side of said diaphragm, said nipples being arranged intermediate the ends of the tank, and inwardly convexed screens running longitudinally of the tank and over the respective nipples to prevent closing 01 the latter by said diaphragm.

2. In a fountain spraying device of the character described, a dispensing tank of elongated form adapted to constitute a reservoir for the liquid to be sprayed, a flexible diaphragm dividing the interior of said tank into two non-communicating chambers, outlet nipples for said tank at opposite sides of said diaphragm, said nipples being of similar form to facilitate connection of either of the same with a source of supply of water under pressure, said diaphragm being of a character to be actuated by said water under pressure when introduced at one side of said diaphragm to substantially completely discharge a liquid to be sprayed from said tank at the opposite side of said diaphragm, said nipples being arranged intermediate the ends of the tank, inwardly convexed screens running longitudinally of the tank and over the respective nipples to prevent closing of the latter by said diaphragm, and a wire arranged outwardly oi each screen and running from end to end of the tank beneath the central portion of said screen to maintain the inwardly convexed form thereof.

3. In a fountain spraying device of the character described, a dispensing tank of elongated form adapted to constitute a reservoir for the liquid to be sprayed, a flexible diaphragm dividing the interior of said tank into two non-communicating chambers, outlet nipples for said tank arranged intermediate the ends of the latter and at opposite sides of said diaphragm, said nipples being of similar form to facilitate connection of either of the same with a source of supply of water under pressure, said diaphragmbeing of a character to be actuated by said water under pressure when introduced at one side of said diaphragm to substantially completely discharge a liquid to be sprayed from said tank at the opposite side of said diaphragm, said tank being composed of longitudinal half sections secured together, and the margin of said diaphragm being clamped between the sections of said tank so as to form a watertight joint therebetween, and means for preventing closing of said nipples by said diaphragm.
