Abstract
Abstract A wheel-mounted housing having an open underside confronting a supporting surface to be treated with material. A pump is mounted to the housing and a crank and pitman assembly connect one wheel to the pump to cause operation thereof. A storage tank with treating material is connected to the housing and conduit means provides passage of material from the tank to the pump. The output of the pump is connected to a spraying nozzle toward the supporting surface upon which the wheeled housing rides.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
177 words
A spraying apparatus comprising a housing having a shielded opening therein directed downwardly for confining the spray zone of a coNfronting surface to be treated, said shielded opening being defined by a plurality of substantially vertical shield portions at the lower edge of said housing and adapted to be located immediately above the ground, a first set of wheels connected with the housing, a tank connected with the housing for containing treating material, a pump connected with the housing for pumping the material and including a stationary portion and a reciprocating portion, flexible hose means connecting the tank to the reciprocating portion of the pump, a crank assembly connected between said first set of wheels and the reciprocating portion of the pump for operating the pump as the housing travels along a supporting surface, a nozzle disposed in the shielded housing and being directed downwardly toward the confronting supporting surface, and conduit means connecting the pump output to the nozzle to generate a spray of material directed toward the surface when the housing travels along the surface.
Claim 2
Dependent Claim
177 words
A spraying apparatus comprising a housing having a shielded opening therein directed downwardly for confining the spray zone of a coNfronting surface to be treated, said shielded opening being defined by a plurality of substantially vertical shield portions at the lower edge of said housing and adapted to be located immediately above the ground, a first set of wheels connected with the housing, a tank connected with the housing for containing treating material, a pump connected with the housing for pumping the material and including a stationary portion and a reciprocating portion, flexible hose means connecting the tank to the reciprocating portion of the pump, a crank assembly connected between said first set of wheels and the reciprocating portion of the pump for operating the pump as the housing travels along a supporting surface, a nozzle disposed in the shielded housing and being directed downwardly toward the confronting supporting surface, and conduit means connecting the pump output to the nozzle to generate a spray of material directed toward the surface when the housing travels along the surface.
Claim 3
Dependent Claim
36 words
The device as set forth in claim 1, together with support means extending back from the housing, and a second set of wheels connected with said support means and spaced behind said first set of wheels.
Claim 4
Dependent Claim
53 words
The device as set forth in claim 2, together with handle means connected to said support means for pushing the device forward with the first set of wheels engaging the ground or with the first set of wheels disengaged from the ground and thereby reducing the force necessary to push the device forward.
Claim 5
Dependent Claim
33 words
The device as set forth in claim 3, together with adjustable valve means disposed in line with the house means, and remote control means for adjusting the regulating condition of the valve means.
Claim 6
Dependent Claim
26 words
The device as set forth in claim 4, wherein said remote control means is mounted on said handle means to permit convenient adjustment by the operator.
Claim 7
Dependent Claim
131 words
The device as set forth in claim 1, wherein said crank assembly includes an arm, means pivotally mounting one end of the arm to the first set of wheels, a first crank handle, means pivotally mounting the free end of the arm to the crank handle, a rotating shaft passing through the housing and secured at the outer end thereof to the first mentioned crank handle, a second crank handle secured to the inward end of the rotating shaft, the second crank handle including a loop head therein, a collar fixedly attached to the reciprocating portion of the pump, a crankpin extending outwardly from the collar and through the loop head to effect rotational displacement therein whereby the pump can be caused to reciprocate resulting in the pumping of material therethrough.
