rection of the axis causing the changing of the effective position of the sleeve 3. In the lower part ofthe cylinder I there is a coiled spring 6 acting on the underside of the piston; this spring is pressed together when the piston moves downwards and is released back to its original position after the compression stroke has been performed. The piston12 is secured to a piston rod 1 the upper part 'I' of which being hollow and embracing the enlarged lower end of the rod 4 with a considerable axial slip thus forming the above mentioned lost-motion device. At the other end .the piston rod 'I is fastened to a plate 9 in form of a bell or an inverted cup, this cup 9 participating in the motion ofthe piston and moving to and fro relatively to the cup 8. This cup 8 is similar in form to the other and preferably at a short distancefrom it and may be integral with the casing 8 surrounding the cylinder andthe reciprocating parts of the device. It will be noted that both cups or agitating members 8 and 9 lhave a conical upper portion and a substantially vertically depending cylindrical lower portion.M At one side of casing 8' there are arranged ,two tubular parts I and II for the connection of hoses IIa and IIa. serving for the introduction and discharge of the .duid un- The part I0 is in communication with the interior of the cylinder I by portsAIZ and the part II also with the interior ofthe cylinder by ports I3. The casing 8 is connected with the cylinder I by partitions I4r and I4a.I soldered or welded or secured thereto in some other .appropriate manner and dividing the space between the'se walls in such a manner that only the communication mentioned above is possible.
The sleeve of slide valve 3 is so arranged in the upper part of the cylinder that it alternately shuts ports I2 and I3. The movement of this valve is limited, upwards by the top plate of the cylinder and downwards Aby a The connecting-rod 4 is joined to the inner ends of the springs 5 by means of a pin I1 slidable in slot I6a of a fork I6 secured to the top plate of the cylinder, the outer vends of the springs beingattached to the inner surface of the sleeve in a suitable manner.
The drawings show the mechanism when the spring 6 of the piston is released, the piston moving upwards and the fluid under pressure escapas the ports I2 are closed. The position of the movable parts represented in Fig. 1 corresponds to the moment in the ascending stroke of the piston when the piston has approached'its uppermost position so far that it is just touching the rod 4 and begins to push it upwards till the end of its stroke. This upward movement is also transmitted to the pin I'I so that the springs in being compressed pass their dead-center posiltion and suddenly turn in a .reversed angular,
position contrary to that shown in the drawings. the Springs 5 exercise a downward push to the 'sleeve 3 thereby shifting it into its lower position till it reaches thestop I5. 'I'he ports I2 are now uncovered and the ports I3 are shut. The fluid under pressure entering by the tubular part I8 is now acting on the piston 2 thereby causing its downward stroke. When a certain 'part of the Way is accomplished the piston gets in touch with the rod 4 and carries it on together with the pin I1, thus bending the springs downwards into the angular position shown in the drawings. springs produce a push acting in an upward div thereof.

It will be noted that'in practical operation the washing apparatus is placed into a. tub I8 containing a washing liquid I9 and the articles to` cross section of which remains substantially constant during the reciprocation of the agitating members. uid motor employed in the apparatus of the invention that the downward movement of the piston will be gradual as the upper cylinder space is filled up with the iluid under pressure. Therefore, the distance between the agitating members will be gradually increased and will be filled up with washing liquid drawn in as by a pump. At-
the same time return spring Ii will be completely compressed. After the piston has reached its lowermost position, slide valve 3 will be reversed in a trigger-like manner and the fluid under Ipressure will be shut oi. As the pressure on the upper surface of the piston will be suddenly re-i moved, piston 2-will be almost instantaneously returned to its uppermost position by return spring 6. Agitating members 8 and 9 will be pressed together at a high speed and will forcibly eject the liquid contained in the space between the upper portions of the agitating members through the constricted annular space 22 between the vertically depending lower portions Thus, the Washing liquid will be ejected at a very high velocity' and pressure and will set up powerful and hig'h speed pulsations in the liquid which will readily loosen the particles of dirt adhering to the articles to be washed.
