Abstract
Abstract A garden and orchard sprayer having identical canister halves which are bolted together with a flexible diaphragm therebetween for the purpose of containing and spraying insecticides, herbicides, etc. Each shell half is identical so a single mold may be used to form same. Each canister shell has a large mouth opening for filling the canister and a hose connection for applying water pressure to one of said canister halves while allowing flow from the duplicate hose connection on the other canister half for the purpose of spraying. An additional feature of this invention is in the operation thereof wherein the over-all canister need be filled with insecticide solution once and from then on the container has the proper amount of water therein for future mixes without any refilling as a separate step.

Claim 1
Independent Claim
217 words
A garden and orchard sprayer assembly for containing and spraying insecticide mixes and the like comprising: means so that the assembly needs to be filled only once including; two identical canister half shells for the assembly each formed with an open end and a substantially closed end, an outer radially extending flange circumferentially around the open end of each canister half shell, the substantially closed end of each canister half shell having an axially extending flanged end portion concentric with the canister walls, a central large mouth opening in the closed end concentrically within the flange end portion of each canister half shell so as to be below the outer edge thereof so that when the large mouth opening is closed with a complementary large mouth plug and the assembly is resting on a surface by means of the axially extending flanged end portion the plug does not touch the surface, a removable large mouth plug mounted in the said central large mouth opening, diaphragm means mounted between the radially extending flanges of the two shells, and an inlet/outlet opening in the closed end of each canister half shell having a hose connection integral therewith and with a coupling end extending outwardly through the axially extending flanged end portion for connection to an ordinary type garden hose.

Claim 3
Dependent Claim
51 words
The structure as set forth in claim 1, wherein the diaphragm means is made of flexible material and functions as a leak sealing gasket between the two canister half shells when said canister half shells are connected together in addition to functioning to separate spray mix from a pressure fluid source.
Claim 4
Dependent Claim
25 words
The structure as set forth in claim 2, wherein the canister means includes recessed handholds integral therewith for permitting easy maneuverability of the sprayer assembly.
Claim 5
Dependent Claim
