Abstract

A machine for directing a high pressure reciprocating spray of cleaning liquid against a shirt collar; comprising a frame, a work table, reciprocating spray suspended above, and pointing downwardly at the work table, a reservoir of cleaning liquid, a pump to supply the cleaning liquid to the nozzle at high pressure, and a means to move the spray in a reciprocating manner.

Claims

1. An apparatus for laundry spray cleaning comprising a housing containing a horizontally positioned open-top tub for containing a reservoir of cleaning liquid, a horizontal work table above said tub to support the item to be cleaned, a spray nozzle suspended closely above said work table and directed to spray said liquid downwardly against said item on the work table while moving in a horizontal reciprocating motion across said work table, a pump to receive said liquid from said tub, pressurize it and deliver, at a pressure of 500-2000 psig, the pressurized liquid to said nozzle, and means to selectively cause said spray nozzle to reciprocate.

2. The apparatus of claim 1 wherein said spray nozzle is moved in said reciprocating motion by the action of a piston in a cylinder of pressurized fluid.

3. The apparatus of claim 2 wherein said cylinder of pressurized fluid is a pneumatic cylinder.

4. The apparatus of claim 1 adapted to spray-clean shirt collars.

5. The apparatus of claim 2 wherein said reciprocating motion is provided by the combination of said spray nozzle being suspended rigidly and vertically from a block sliding horizontally in a track and with said block being fastened to said piston.

6. A shirt collar cleaning machine comprising a housing containing horizontally positioned, open-top, rectangular tub adapted to function as a reservoir for cleaning liquid, a work table adapted to support a shirt collar and positioned horizontally and overhanging a portion of said open-top, a spray pipe suspended vertically above said work table and terminated at its lower end by a spray nozzle pointing downwardly and positioned a few inches above said work table, a pump to provide liquid at a pressure of 800-1500 psig to said spray pipe and nozzle and having its suction inlet connected to said tub and its outlet connected to said spray pipe;

a pressurized fluid cylinder with a piston rod extending outwardly of said cylinder and moving horizontally and reciprocatingly when said fluid is pressurized, sliding support means connected to said piston and to said spray nozzle pipe; and

selective means to cause said piston to move horizontally and reciprocatingly.

7. The machine of claim 6 wherein said cylinder is a pneumatic cylinder.

8. The machine of claim 6 wherein said support means is a block sliding horizontally in a track.

9. The machine of claim 6 wherein said pump outlet and said spray nozzle pipe are connected by a flexible tubing suspended above said support means.
