Abstract
1,197,425. Windscreen wipers. FORD MOTOR CO. Ltd., 5 May, 1969 [6 June, 1968], No. 22734/69. Heading A4F. [Also in Divisions H1 and H2] In a windshield wiper control system, a wipe cycle is initiated by actuating switch 11 to close contacts 3, 4, and open contacts 1, 2. Motor 17 then causes movement of the wiper system from a park position to the normal wipe cycle and constant repetition of the cycle. A power signal is maintained on circuit B during movement from the park position, and, up to the start of the wipe cycle, an earth signal is applied to circuit C whilst circuit A is changed to a power signal. When a wipe cycle commences, the power signal remains on circuit B, circuit C receives a power signal, whilst circuit A has an earth signal over the major portion of each wipe cycle. At the end of each cycle, the signals on circuits A, C, are interchanged. Contacts 1, 2, are closed and contacts 3, 4, are opened for return to a park position, the motor circuit being completed through lead 24. The motor is reversed by the interchange of signals on circuits A, C, and the motor is braked when both circuits receive earth signals. A switch 23 has terminals 22, 42, 43, associated with the circuits B, A, C, respectively as well as an earth contact 48. Strips 51, 52, are adapted to interconnect contacts 67, 48, respectively with contacts 46, 44. A pivotable element 53 associated with cam 54 enable the various signals to be applied to the circuits A, C, the cam being driven in synchronism with the motor. Initially, pivotable cam follower 62 engages stop surface 67 whereby surface 57 does not actuate strip 51 whilst surface 58 actuates strip 52 to apply an earth signal to circuit A. Rotation of the motor causes the follower 62 to move along track 68 to ramp 69 whereby neither of the strips 51, 52, are deflected. Further rotation of the cam causes the follower 62 to move up the ramp 69 and around the surface 71 so that strips 51, 52, are both pivoted to apply an earth signal to circuit A and a power signal to circuit C. The interchange of signals on circuits A, C, is effected when the cam follower reaches step 72. Thereafter, the follower moves up the ramp 69. If the switch 11 has been moved to close contacts 1, 2, the interchange of signals causes the motor to reverse and the follower 62 moves along track 68 until it engages stops surface 67. The length of the track 68 determines the distance through which the wiper blades are moved from the wipe cycle to the parked position.
