Index type-wheel machines for marking laundry articles; pad inking-arrangem ents. -(1) In arrangements in which an inking- pad is rocked against and away from the type-wheels and is then moved laterally to allow the impression stroke to be made, the lateral movement is controlled by a lever which is held stationary by a concentric part on the operating-cam while the pad is being rocked. As shown, the pad 27, Fig. 1, is secured to a slide 23 which is mounted in a guide 22 pivoted at 30. The operating-cam 32 engages a nose 31 on the guide and a roller 33 on a lever 19 which engages a slot 20 in the slide. When the shaft 9 of the cam is rotated, the pad is initially rocked against the type-wheels 1 by the cam and is then returned by a spring 55, the concentric part 32a of the cam meanwhile holding the lever stationary. A part 32b of the cam then comes opposite the roller 33 and permits a spring 34 to move the pad laterally. In 'a modification, the pad may be mounted to move vertically on a laterally movable carrier. The pad may be inked by means of a supply-pad in a receptacle 57 mounted on a vertically movable support 2 for the type-wheels, the supply-pad being depressed on to the pad 27 at each operation. The receptacle 57 is normally closed at the bottom by a finger 59 on the lever 19.

The liquid may be syrup or concentrate which is mixed with water by the injector principle. The valve 10 is spring-biased closed and solenoid controlled by a timer. When the valve 10 is closed the spring causes initial bowing of the valve member 13, Fig. 4, but the member rapidly returns to its planar form to apply a suction to the water inlet 8 to retract the water from the end of the inlet, Fig. 7 (not shown). If a highly viscous liquid is dispensed a plug of liquid forms in the outlet 9 when the pump and water flow are stopped to seal the outlet. If a lower viscosity liquid is used the level of liquid in the mixing chamber falls to the level of the outlet, Figs. 8 and 9 (not shown), when the pump stops. The pump 5 has an impeller 6 mounted on an eccentric axis in the pump housing and the blades of the impeller are elastically yieldable. The blades are deformed by the housing wall and define pockets which expand at the pump inlet 5a to apply a suction and are compressed at the pump outlet 5b to pressurize the discharged liquid to a mixing chamber.
