Application led May 28, 1915. Serial No. 31,035.
to the dischargingy nozzle and is directed' onto plants, trees,l shrubbery, etc., and my said invention primarily has for its object to provide' a spraying device of the general character stated, of a simple and economical construction, and of few parts that. can be conveniently 'manipulated for e'ectively serving their intended purposes.
With other objects lin View that will be hereinafter referred to my invention embodies the peculiar construction and novel arrangement of the parts hereinafter eX- plained, specifically pointed out in the appended claims and illustrated in the accompanying drawings, in which.-
Figure l is a vertical longitudinal section of my improved' spraying device. Fig. 2
is a horizontal section thereof on the line 2 2 of Figui. Fig. 3 is a perspective view of one of the spraying solution blocks hereinafter referred to.
rlhe body of the sprayer is in the naturev of a cylinder 4, the upper and lower ends of 1 which are externally threaded to receive the upper and lower cap members 20l and 8. Cap member 20 has acontracted threaded upper end that receives a spraying nozzle 1, as shown; and its lower end is threaded as at 3 for threading .onto the upper end of the cylinder 4.
9 designates an elbow shaped member that forms a Huid connection for joining the sprayer with the source of Huid supply and the said member includes a neck 90 that is externally threaded as at 91 to t into the threaded passage 80 in the lower cap 8.
6 is a perforated tube threaded at ythe lower end for removably connecting it to the threaded neck 90 of the Huid connection 9 and the said tube 6,'which extends the full length of the cylinder 4, has its upper end projected to discharge into the nozzle 1, as is clearly shown in Fig-1 of the drawing.
7 designates a soluble material in the nature of a block or cartridge made'of suitable composition, chemically hardened, andl which is slowly dissolved by the passing iuid, and the said block is of a diameter to snugly fit within thecylinder 4 and has a central bore for slidably engaging the perforated tube 6.
10 designates a handle on the lower end of a valve rod 16 that slides in a stuii'ing box l1 in the connection 9 and entends up into the tube 6 and carries a ball valve 5 slidably mounted in the said tube 6. y
14 designates a stop flange within the tube 6 that prevents the ball valve from choking the nozzle 1 in-case it should become loose from the rod or stem 10, or the fluid pressure tend to force it to the upper end of the tube 6. Y f
From the foregoing taken in connection with the drawing, the construction of my. improved spraying device will be readily understood. l
By reason of mounting the soluble block 7 within the cylinder 4 and on the tube 6, as shown, the iuid that enters the cylinder, asit passes into the lower end of the tube 6 discharges through the perforations 60 into the cylinder and seeps through the soluble block 7 and, mixed with the solution it Specification of Letters Itatent.- I PaQMtU-@d @eau :i145 39H50 i passes back'into the tube 6 above the valve n 5 when the latter is adjusted as in Fig. 1.
.By providing a. central tube 6 that extends the full len th of the cylinder, mounting the soluble lock 7 and providing a valve control, as shown, the force and volume of Huid entering the cylinder to mix withy the soluble block 'can be readily regulated, it being understood that by adjusting` the valve 5, to the position shown by dotted lines X on Fig. 1, the water that passes into the cylinder, vby reason of passing back into the tube 6 before it rises against the block 7, will become less saturated with the soluble substance than is the case when the ball valve 5 is located above the block 7, as shown in full lines in Fig. 1. Again, by reason of using the material that is to be. placed in solution, in block form, a plurality of such blocks may be readily mounted on the tube '6 within the cylinder 4 when a very strong spray solution is desired.
I'llhe several parts that constitute my spray device may be readily disconnected for cleaning and quickly reassembled.
What l claim is:
l l. The combination of a cylinder having a nozzle at one end and inlet connection at the other end adapted for being connected to a source of fluid supply, a perforated tube that .extends the full length of the cylinder whose upper end discharges into the nozzle` and whose lower end joins the inlet connection, a soluble chemical block fitting within the cylinder between the said cylinder and the perforatedtube and a body slidable longitudinally within the perforated tube to act as a dam or cutoff.
2. rllhe combination of a cylinder having a nozzle at one end and inlet connection at the other end adapted for being connected to a source of fluid supply, a perforated tube that extends the full length of the cylinder whose upper end discharges intothe nozzle and whose lower endjoins the inlet connection, a soluble chemical blocklitting within the 'cylinder between the said cylinder and the perforated tube, and a valve slidably mounted within the perforated tube-.for controlling the flow of fluid through the said tube, said valve having a rod that extends through and outside of the fluid connection at the lower end of the cylinder.
3. A spraying device comprising a cylinder having a discharging nozzle at one end, a pipe connection at the other end for joining the same with a source .of fluid supply, a perforated tube within the said cylinder detachably connected with the supply pipe connection, a valve slidable in the tube Whose rod passes through the pipe connection .and a soluble chemical block mounted on the perforated tube and engaging the cylinder.
