v SPRAY NoZzLE Jan. 14, 1941.
Filed Feb. 15, 1940 Huw 'VITA-JESS Patented Jan. 14, 1941 UNITED STATES SPRAY NOZZLE Gustav Olson, Woburn, Mass.
Application February 15, 1940, Serial No. 319,138
2 Claims. l (Cl. 299-140) The invention relates to devices for spraying insecticides, fungicides and disinfectants in the control of bugs, insects, Worms and fungae, and for disinfecting hen-houses or other buildings,
soil, etc.
The object of the invention is to provide a new and improved and a simple and inexpensive spray nozzle readily attachable to an ordinary garden hose and so constructed that the discharge of water from the nozzle will draw a spray liquid from a suitable container, mix it thoroughly with the water, after the latter has left the nozzle to form a spray of desired strength and discharge this spray where desired with un- 5 usual force and with no danger of any resins, fats, oils or other substances in the insecticides or the like being used, clogging any part of the nozzle to interfere with proper performance of the spraying operation.
With the foregoing in View, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying draw- 111g.
Figure 1 is a side elevation showing the nozzle connected with a garden hose and with a suction hose leading from a quantity of spray liquid in a container.
Figure 2 is a central vertical longitudinal sectional view through the nozzle.
Figure 3 is a transverse sectional View on line 3-3 of Fig. 2.
In the drawing above briey described, a preferred construction has been illustrated and 5 while this construction will be specifically explained minor variations may, of course, be made within the scope of the invention as claimed. i
The nozzle includes a casing 5 comprising two 4 parallel substantially vertical side walls' 6, a longitudinal top wall l, a forwardly inclined bottom 8, a substantially vertical back wall 9, a forwardly projecting neck I0 at the front acute corner of the casing, a rearwardly open water inlet socket Il at the rear acute corner threaded for connection with an ordinary garden hose I2, a cap I3 threaded on the neck I Il and having a front wall I4 formed with a water discharge orice I5, a boss I 6 carried by the 50 upper portion of the back wall 9, and a lug I 'I projecting downwardly from the top wall 'l and extending between the side walls 6.
A spray liquid tube I8 is threaded through the boss I6 and lug Il and is disposed through- 55 out the greater part of its length within the casing 5, said tube I8 having a reduced front end I9 which projects forwardly a slight distance, preferably aboutone-sixteenth of an inch, through the orifice I5, said tube end I9 being spaced from the wall of said orifice to leave a water discharge space 20. The effective size of 5 24 in a jar 25. 15
'Ihe discharge of water through the orifice I5 creates suction in the tubes I8 and 23, thus drawing the spray liquid 24 and causing discharge thereof from the front end of the tube I8 into the water after the latter has discharged through said orifice I5. 'I'he spray liquid and water are thoroughly mixed to form a spray of desired strength and this spray may be deposited wherever desired. By having the spray liquid 25 mix with the water after the latter has left the casing 5, it is insured that any resins, fats, oils or other substances in the spray liquid shall not clog any part of the nozzle. Moreover, the improved nozzle will discharge a much more forcible 30 spray than prior art nozzles in which internal suction-and mixing occur and the force of the water is expended somewhat before discharge.
From the foregoing taken in connection with the accompanying drawing, it will be seen that a simple, inexpensive and efficient device has been provided, one which will be long-lived and trouble-free and one which will be advantageous from all standpoints. While the device has beendescribed in one position, it may of course be used in any desired positions to reach the zones to be sprayed. The novel casing structure and the rearwardly projecting tube portion 22' cooperate in forming a pistol-grip formation which may be conveniently held inl one hand.
I claim:
1. In a spray nozzle, a casing comprising two spaced Vtriangular substantially vertical side Walls,
a longitudinal top wall, a substantially vertical back wall, a forwardly inclined bottom, a forwardly projecting neck at the front acute corner of the casing, a rearwardly open water inlet socket at the rear acute corner threadedy for connection With an ordinary garden hose, a cap threaded on said neck and having a front wall after discharge of the latter from said casing and will mix the spray liquid with the discharged water, and a lock-nut on said tube abutting said boss, the construction of said casing and said rearwardly projecting portion of said tube cooperating in forming a pistol-grip formation which may be conveniently held in one hand.
2. In a spray nozzle, a casing comprising two spaced triangular vertical side walls, a horizontal top wall, a substantially Vertical back wall, a forwardly inclined bottom, a water inlet socket at the rear acute corner of the casing and opening in a rearward and downward direction for connection with an ordinary garden hose, and a closure for the front acute angular end of said casing and having a Water discharge orifice; and a spray liquid conducting tube passing through the upper end of said back wall and terminating in operative relation with said orifice, said tube having a portion projecting rigidly rearward from said back wall; the construction of said casing and the association of said rearwardly projecting tube portion cooperating in forming a pistolgrip formation which may be conveniently held in one h-and.
