Estimating the term…
A portable wall and ceiling texture machine applicator is housed in a relatively small cabinet mounted on relatively large rear wheels for easy pulling up stairs and on swivel front casters for easy steering. A first material delivery system includes a variable speed pump which delivers particulate texture material at a selected flow rate which enables a creative application of texture. A completely separate delivery system delivers pressurized air to a spray head which merges the particulate texture material and pressurized air to spray it onto a wall or ceiling. Separate power cords supply energy for delivering the particulate texture material and pressurized air so that existing 15-amp house supply circuits may be used. The spray head may be on either a pole gun or a hand gun. A check valve on the spray head prevents a back flow of the particulate material when the spray head is turned off.
A portable applicator machine for applying any selected one of a plurality of known particulate textured surfaces onto walls or ceilings, said machine comprising a cart having a housing mounted on two relatively large rear wheels and front supports, said large wheels having a diameter which is large enough to easily roll up or down stairs, said housing including a hopper for holding said particulate texture material, a spray gun for applying said particulate texture material to said walls or ceilings, first delivery means comprising means for pumping said particulate texture material from said hopper through a variable speed pump driven by a first electric motor for transporting said particulate texture material from said hopper through a hose to said spray gun, second delivery means separate from said first delivery means, said second delivery means comprising compressor means driven by a second and separate electric motor for delivering pressurized air through a separate hose to said spray gun in order to drive said particulate texture material out of said spray gun, at least one nozzle tip orifice to provide a selected diameter through which said particulate texture material is delivered under the urging of said variable speed pump and said pressurized air.
A machine comprising a portable cart having a housing for receiving and delivering particulate texture material for texturing a wall or ceiling surface with a layer of particulate texture material deposited in a preselected one of several patterns, an air compressor on said cart, a spray head, two separate delivery systems, one of said delivery systems comprising variable speed means driven by a first motor for delivering said particulate texture material through a hose to said spray head with a preselected flow rate, the other of said delivery systems comprising other means driven by a second motor for separately delivering pressurized air through a separate hose to an outlet within said spray head for propelling said particulate texture material away from said spray head, said first and second motors being electrically independent of each other, each of said delivery systems comprising a combination of hoses and valves having internal bores of matched diameters to prevent turbulence in the delivery of said particulate texture material and said compressed air, and means for attaching a selected nozzle having an orifice with a particular diameter to said spray head for delivering said air and particulate texture material away from said spray head and toward said wall and ceiling.
A machine comprising a portable cart having a housing for receiving and delivering particulate texture material for texturing a wall or ceiling surface with a layer of particulate texture material deposited in a preselected one of several patterns, an air compressor on said cart, a spray head, two separate delivery systems, means for separately driving each of said delivery systems from differently fused electrical circuits whereby said machine does not draw more current than any one of the fuses can deliver, one of said delivery systems comprising variable speed means driven by a first motor for delivering said particulate texture material through a hose to said spray head with a preselected flow rate, the other of said delivery systems comprising means driven by a second motor for separately delivering pressurized air through a separate hose to an outlet within said spray head for propelling said particulate texture material away from said spray head, each of said delivery systems comprising a combination of hoses and valves having internal bores of matched diameters to prevent turbulence in the delivery of said particulate texture material and said compressed air, means for attaching a selected nozzle having an orifice with a particular diameter to said spray head for delivering said air and particulate texture material away from said spray head and toward said wall and ceiling.
