Title: Improvements in or relating to windscreen wipers
IPC: H02K33/02
Filed: 1924-01-15
Abstract: 230,220. Melmore, W. M. Jan. 15, 1924. Windows and the like, cleaning.-A wiper is oscillated over the screen by means of a solenoid and plunger, and thermostatic control devices may be provided to give an intermittent action with a delay between the oscillations, the period of delay being variable. A soft-iron tube 1 adapted to be fixed to the edge of the screen has pole-pieces 2, 4 between which is secured a brass tube 3 having wound around it the solenoid 5. Within the tube 3 slides the iron plunger 6 having rack teeth 7 engaging a pinion 8 fast on a spindle 9 carrying the wiper. The plunger is guided by rods 11 and normally held against a rubber disc 13 by springs 12. When a pushbutton is pressed to energize the solenoid 5 the plunger 6 is drawn into the tube 3 thus rocking the wiper, and on release of the button the springs 12 return the parts to the normal position. An adjustable air-valve may be provided in the pole-piece 2 to vary the speed of the wiper. To give intermittent action a deformable drum 19 filled with methyl ether is fitted in an extension of the casing 1 and wound with resistance wire connected in series or in parallel with the solenoid 5. Current passing heats the drum which expands until a spring 22 fixed to it separates contacts 23, 25 to break the circuit until the drum has cooled sufficiently, when contacts 23, 25 are again made. The contact screw 25 is adjustable in the ebonite end 21 of the casing 1 so that the period of delay can be varied. Instead of a drum a Bourdon tube or a bimetallic strip, wound with resistance wire, may be employed. The push-button is of the type which may be closed momentarily or manipulated so as to remain closed. One Provisional Specification describes also a switch operated by the plunger at the end of each stroke to give continuous oscillation of the wiper. Specification 15609/14, [Class 106 (i), Calculating &c.], is referred to.
