Abstract

Abstract A corrosion resistant molded polyethylene tank for lawn and garden sprayable solutions is mounted to a manually propelled wheeled cart by a corrosion free attachment arrangement. Opposed sides of the tank are provided with relatively deep angled grooves or tracks engageable with and slidable on opposed, rearwardly extending and upwardly inclined frame components on the cart so that the tank can only be mounted from the rear of the cart with proper registration therewith assured. A removable stop between the frame components at the rear of the tank prevents tank displacement from the cart. A power spray mechanism is mounted to a support cover on the tank or, in a second embodiment, to a separate engine mount carried by the frame and seated against the stop.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 122 words
A utility sprayer unit, comprising: a support base having opposed sides and a front and rear, opposed spaced and parallel upstanding frame members secured respectively to said opposed sides, a tank having opposed sides each provided with a groove on the exterior surface thereof with said grooves being in parallel relationship to each other, the distance between the recessed end portions of said grooves corresponding substantially with the distance between said frame members, said tank being disposed on said base intermediate said frame members with said respective frame members nested in a respective groove to frictionally engage said tank and hold it securely on said base, and said tank being adapted for cooperative association with a power operated pump and spraying mechanism.
Claim 2
Dependent Claim 122 words
A utility sprayer unit, comprising: a support base having opposed sides and a front and rear, opposed spaced and parallel upstanding frame members secured respectively to said opposed sides, a tank having opposed sides each provided with a groove on the exterior surface thereof with said grooves being in parallel relationship to each other, the distance between the recessed end portions of said grooves corresponding substantially with the distance between said frame members, said tank being disposed on said base intermediate said frame members with said respective frame members nested in a respective groove to frictionally engage said tank and hold it securely on said base, and said tank being adapted for cooperative association with a power operated pump and spraying mechanism.
Claim 3
Dependent Claim 64 words
A sprayer unit as defined in claim 1 wherein: said tank includes a top and the upstanding ends of said frame members being substantially planar therewith when said tank is disposed on said base, and a stop member releasably secured to and between said upstanding ends and in engagement with said tank to prevent any movement of said tank relative to said frame members.
Claim 4
Dependent Claim 79 words
A sprayer unit as defined in claim 1 wherein: said tank includes a top and a back connected thereto, the upstanding ends of said frame members being substantially planar with the juncture of said top and back, and a stop member secured to and between the upstanding ends of said frame members and in engagement with said tank to prevent any tank movement relative to said fraMe members and said base when said tank is positioned on said base.
Claim 5
Dependent Claim 53 words
A sprayer unit as defined in claim 3 including: said tank being provided with a separate groove at the juncture of said top and back with said separate groove extending to and between said opposed sides, and said stop member being nested in said separate groove and releasably secured to said frame members.
Claim 6
Dependent Claim 35 words
A sprayer unit as defined in claim 1 including the walls defining said grooves being converged from the external surface of said tank towards their innermost depth to facilitate frictional engagement with said frame members.
Claim 7
Dependent Claim 32 words
A sprayer unit as defined in claim 1 including: a ground engaging wheel assembly carried by said base, and a handle unit operatively secured to the upstanding ends of said frame members.
Claim 8
Dependent Claim 43 words
A sprayer unit as defined in claim 1 wherein: said tank includes a flat top surface provided with a relatively large opening, a rigid cover removably arranged relative to said opening, and said cover adapted to support any selected engine powered spray assembly.
Claim 9
Dependent Claim 90 words
A sprayer unit as defined in claim 1 including: a platform designed to support any selected engine powered spraying assembly, means mounting said platform to said frame members so that said platform is disposed horizontally in close spaced relationship above said tank, means on said tank affording operably connection with any selected engine powered spray assembly on said platform with the contents of said tank, and said platform serving to isolate said tank from any vibrations emanating from the operation of an engine powered spray assembly mounted on said platform.
Claim 10
Dependent Claim 161 words
A sprayer unit as defined in claim 1 wherein: said tank includes a top and a back connected thereto, the upstanding ends of said frame members being substantially planar with the juncture of said top and back, a stop member secured to and between the upstanding ends of said frame members and in engagement with said tank to prevent any tank movement relative to said frame members and said base when said tank is positioned on said base, a platform for supporting any selected engine powered spray assembly, means for removably mounting said platform to said frame members and engageable with said stop member whereby said platform is disposed horizontally in close spaced relationship above said tank, said stop member serving to limit the movement of said platform relative to said frame members towards said tank, and said platform serving to isolate said tank from any vibrations emanating from the operation of an engine powered spray assembly mounted on said platform.
Claim 11
Dependent Claim 135 words
A sprayer unit as defined in claim 1 including: said frame members being secured to said opposed sides of said base at respective points near the front thereof and extending angularly therefrom upwardly and rearwardly, said grooves on said tank being angularly inclined correspondingly to the angle of inclination of said frame members, the nesting of said frame members in said grooves effected by the introduction of said grooves into an angled slidable engagement with said frame members only from a position at the rear of said base, and said grooves being relatively deep to substantially embrace said frame members whereby the cooperative engagement between said frame members and said grooves in mounting said tank to said base prevents any vertical or horizontal misalignment of said tank relative to its proper positioning on said base.
Claim 12
Dependent Claim 106 words
A sprayer unit as defined in claim 10 including: a platform for supporting any selected engine powered spray assembly, means for slidably mounting said platform to said frame members, a stop member mounted to said frame members and engageable by said platform whereby said platform is disposed horizontally in close spaced relationship above said tank, said stop member serving to limit the movement of said platforM relative to said frame members towards said tank, and when said platform has an engine powered spray assembly mounted thereto, the weight thereof serves to restrict the movement of said platform relative to said frame members away from said tank.
Claim 13
Dependent Claim 75 words
A sprayer unit as defined in claim 10 including: said base being provided with an opening, said tank including a bottom provided with a depending sump extended through said opening when said tank is disposed on said base, and said opening being oversized relative to said sump to provide for adequate entry clearance of said sump into said opening during its angled direction of movement as said tank is slid relative to said frame members.
