Title: Improvements in or relating to windscreen wipers
IPC: B60S1/42
Filed: 1948-11-23
Abstract: 685,291. Windscreen cleaners. O'SHEI, W. E. Nov. 24, 1949 [Nov. 23, 1948; Dec. 22, 1948], Nos. 30468/48 and 33007/48. Class 138 (i). A windscreen wiper of the type wherein the blade is mounted so as to be angularly movable with respect to the radial direction of the wiper arm and wherein resilient means are provided for normally holding the blade at any desired angle relative to the arm in such a manner that the blade can be twisted into a position deviating therefrom against the action of the resilient means, in which the resilient means comprises a helical compression spring. A diecast housing 12 which receives an arm 11 is pivotally connected to a wiper blade 2 by a rod 7 with a collar 7a passing through two relatively movable ears 1, 3 urged apart by a helical spring 6. The ear 1 is fixed to a channel member 16 secured to the blade by a rivet 17 and the back of the channel is provided with a T-piece 15 stamped-up therefrom to form a pivot 5. The movable ear 3 forms one limb of an L-shaped member the other limb 4 of which has a slot 18 to engage the stem of the T-piece. When the blade is moved angularly with respect to the arm in the plane of the windscreen the housing 12 swings about the fixed ear 1 and the movable ear 3 pivots transversely of the blade and also moves towards the ear 1 thus compressing the spring 6 which tends to restore the parts to a position in alignment with the blade. The T-piece may be replaced by a rivet. If it is desired that the blade shall move angularly to only one side of the normal position, a stop or other means may be provided to prevent relative movement in the opposite direction. Rocking movement of the blade relative to the housing, in order that the blade may incline to a trailing position as it moves over the windscreen, is limited by the ears engaging the side walls of the housing as described in Specification 685,290. The movable ear may be dispensed with and the helical spring would then bear at one end on the fixed ear and at the other end on the remote end wall of the housing. Specifications 512,138, 523,177, 657,822 and 685,307 also are referred to.
