Abstract
854,523. Windscreen wipers. TRICO PRODUCTS CORPORATION. Dec. 5, 1956 [Dec. 5, 1955], No. 37210/56. Addition to 828,298. Class 138(1). The spring hinge of the wiper of the parent Specification is made adjustable, a thumb adjustment being provided in the form of a disc 23 pivoted at 24 on the lever 14 and having a stepped series of seats 25 for selectively receiving the spring terminal 21. The series of seats extends about the pivot 24 on an eccentric arc so that the successive seats serve to support the terminal 21 at different elevations and thereby increase or decrease the spring stress accordingly. The seats 25 are cam-like in shape to ease the spring terminal out of one seat and into the next. In a modification, Fig. 9, the superstructure levers 1411, 15<SP>11</SP> are hinged together by a pin 17<SP>11</SP>. A tension spring 18<SP>11</SP> is anchored by a pin 19<SP>11</SP> at one end and by a connector plate 32 engaging into hook 33 in an eccentric opening 34 provided in an adjustment disc 23<SP>11</SP>, the latter being given floating support within slots 35 formed in the side flanges of the channel-sectioned lever 15<SP>11</SP>. The periphery of the disc is formed with a series of seats 25<SP>11</SP> for engaging in the adjacent end walls of the slots 35 under the urge of the spring 18<SP>11</SP>, and when adjustment is desired, the oppositely projecting portions of the disc are engaged between the thumb and forefinger and bodily withdrawn against the spring tension, then rotated, and finally released to-present another selected .pair of seats 25<SP>11</SP> to the end walls of the slots 35. This adjustment serves to rotate the eccentric opening 34 to vary the stress in the spring 18<SP>11</SP>. An additional modification is that pressure is transmitted from the arm-attaching member to spaced points on the central part of the blade unit by means of a yoke member instead of to a single point as in the wiper of the parent Specification. Specifications 702,849, 702,899 and 702,900 also are referred to.
