Description: |
| Abstract:
The main object is to produce a machine which will effectually cleanse the coarsest or finest clothing or fabrics in the least possible time without liability of mutilating or otherwise injuring the fabric. This object is best carried out by the use of inverted cup-shape piston is reciprocally movable in the vat into and out of contact with the clothes, so as to force the cleansing fluid back and forth through the interstices of the fabric by varying air pressures. Another object is to transmit motion from the motor to the pistons without in any way obstructing or restricting the full opening in the top of the vat for the free insertion and removal of the clothes. A further object is to provide means for automatically and intermittingly shifting the position of the pistons step by step rotarily so as to bring them into contact with all portions of the clothes during successive compression strokes.
Claim:
In a laundrying machine, a vat, a plunger extending through the bottom of the vat, a yoke mounted on the plunger and movable relatively thereto, a piston mounted on the yoke, spring connections between the plunger and yoke, and means connected to the plunger for reciprocating the same. |
