Oscillating spray-cleaning device

Claim 2

A spray-cleaning device comprising a movable platform, swiveled holder means on the platform arranged for holding a spray nozzle in a generally horizontal and forwardly directed position, and means to swing the holder means and nozzle laterally through a limited arc of travel relative to the platform whereby to spray a fluid delivered to the nozzle under pressure in a flushing action over a surface strip forwardly of the device, said swiveled holder means swinging about a rearward point through a relatively small arc on each side of a directly forward position.

Claim 3

A spray-cleaning device as set forth in claim 1, including handle means secured to the platform and extending upwardly and rearwardly therefrom and wheel means under the platform to facilitate manual movement thereof.

Claim 4

A spray cleaning device as set forth in claim 2 wherein said wheel means for the platform are disposed at a rearward position to permit the nozzle to be tilted up and down during movement thereof to direct the spray to a selected area.

Claim 5

A spray-cleaning device as set forth in claim 1, wherein said handle is hollow and arranged to pass the cleaning fluid from a supply to the nozzle.

Claim 6

A spray-cleaning device as set forth in claim 1 wherein said platform is in the form of a housing generally enclosing the holder means and nozzle and having a forward aperture through which the spray from the nozzle may pass.

Claim 7

A spray-cleaning device as set forth in claim 1 wherein, said swiveled holder means includes means to releasably secure the nozzle and a hose coupled to the nozzle in place on the platform.

Claim 8

An oscillating spray-cleaning device comprising a movable platform having wheels and a handle extending rearwardly from the platform for manual movement thereof, a spray nozzle, a swiveled nozzle holder member mounted on the platform including pivot means for a rearward position of the holder member to permit the forward end portion to swing through a limited arc of travel, said holder member supporting the nozzle in a generally horizontal and forwardly directed position above the platform, and a lever-operated mechanism arranged to swing said holder member laterally from side to side whereby to spray a fluid delivered under pressure into the nozzle.

Claim 9

An oscillating spray-cleaning device comprising a movable platform having wheels and a handle extending rearwardly from the platform for manual movement thereof, a spray nozzle, a swiveled nozzle holder member mounted on the platform including pivot means for a rearward position of the holder member to permit the forward end portion to swing through a limited arc of travel, said holder member supporting the nozzle in a generally horizontal and forwardly directed position above the platform, and a lever-operated mechanism arranged to swing said holder member laterally from side to side whereby to spray a fluid delivered under pressure into the nozzle.

Claim 10

An oscillating spray-cleaning device comprising a movable housing having a forward opening and a hollow handle opening into the housing and extending rearwardly and upwardly therefrom, a spray nozzle, a hose extending through the handle and coupled to the nozzle, a swiveled nozzle holder member mounted in the housing including an elongated support member pivotally mounted at its rearward end to the base of the housing, an annular clamp means to secure the nozzle in a generally horizontal and forwardly directed position for oscillatory lateral movement from side to side through a limited arc of travel, and a manually actuated mechanism for oscillating the swiveled holder and nozzle including a spring member secured to one side of the support member to pull it to one side position and a cable attached to a pivotal lever on the handle to pull the support member to an opposite side position whereby to spray a fluid delivered under pressure through the hose into the nozzle in a flushing action over a strip of surface forwardly of the device.

Claim 11

An oscillating spray-cleaning device comprising a movable housing having a forward opening and a hollow handle opening into the housing and extending rearwardly and upwardly therefrom, a spray nozzle, a hose extending through the handle and coupled to the nozzle, a swiveled nozzle holder member mounted in the housing including an elongated support member pivotally mounted at its rearward end to the base of the housing, an annular clamp means to secure the nozzle in a generally horizontal and forwardly directed position for oscillatory lateral movement from side to side through a limited arc of travel, and a manually actuated mechanism for oscillating the swiveled holder and nozzle including a spring member secured to one side of the support member to pull it to one side position and a cable attached to a pivotal lever on the handle to pull the support member to an opposite side position whereby to spray a fluid delivered under pressure through the hose into the nozzle in a flushing action over a strip of surface forwardly of the device.

Claim 12

A spray-cleaning device comprising a movable platform, swiveled holder means on the platform arranged for holding a spray nozzle in a generally horizontal and forwardly directed position, and means to swing the holder means and nozzle laterAlly through a limited arc of travel whereby to spray a fluid delivered to the nozzle under pressure in a flushing action over a surface strip forwardly of the device, said means to swing including a tension member connected to one side of the holder means and a lever-operated cable connected to the other side of the holder means.

Claim 13

A spray-cleaning device comprising a movable platform, swiveled holder means on the platform arranged for holding a spray nozzle in a generally horizontal and forwardly directed position, and means to swing the holder means and nozzle laterAlly through a limited arc of travel whereby to spray a fluid delivered to the nozzle under pressure in a flushing action over a surface strip forwardly of the device, said means to swing including a tension member connected to one side of the holder means and a lever-operated cable connected to the other side of the holder means.
