Title: Improvements in windscreen cleaning systems
IPC: B60S1/48
Filed: 1957-02-21
Abstract: 858,364. Windscreen cleaners. TRICO PRODUCTS CORPORATION. Feb. 21, 1957 [Feb. 21, 1956], No. 5909/57. Class 138(1). A windscreen cleaning system comprises a combination of a wiper motor with a speed control, a power-operated speed selector serving to move the control to predetermined positions corresponding to different speeds, and a manual actuator for causing operation of the speed selector. The wiper motor, Fig. 3, is of the dual range type disclosed in Specification 820,021 and comprises a kicker 19 that is shiftable to one or other of two positions by piston 22 so as to impart to the wipers a panoramic range or a frontal area range. Chambers 23, in which piston 22 operates, is connected by conduit 30 to power-operated speed selector 31, Fig. 2, in which coupler rod 44 supports diaphragms 36, 37, 38 which partition the selector casing into low speed chamber 51, intermediate speed chamber 52, high speed chamber 53 and washer energizing chamber 54. The forward end of rod 44 is connected to a wiper control valve 62 which is formed with a recess 63, Fig. 15, for connecting supply passage 27 of the wiper motor to a graduating port 64 in a manner either to block off the port from the passage for parking the wiper, or to bring the port and passage into communication to three different extents for low speed, intermediate speed or high speed wiper operation. The speed selector is controlled by a multi-ported valve which is connected to chambers 51-53 via nipples 55-57. Thus, for example, the application of suction to low speed chamber 51 acts upon diaphragm 36 which moves rod 44 along with valve 62. Passage 47, Fig. 2, is also connected to the multi-ported valve in order that the wiperrange may be adjusted. A manual actuator for controlling the multi-ported valve is disclosed in connection with Figs. 5-7 (not shown). On operation of the washer, suction is applied to chamber 54 via nipple 58. Diaphragms 36-38 are thus moved to the left so that the wiper motor operates at high speed if it has originally been set to a lower speed or to the parked position. Specifications 849,908 and 857,490 also are referred to.

Abstract: 1,000,104. Valves. ROBERTSHAW CONTROLS CO. Feb. 14, 1963 [Feb. 27, 1962], No. 6070/63. Heading F2V. [Also in Division G3] A pneumatic relay responsive to temperature or both temperature and pressure signals, has the signal transmitted to the pilot valve by a lever system. A lever 13, pivoted about an adjustable pivot C, Fig. 6, and pivots A and B, receives a temperature signal supplied by a temperature responsive device 10 through a lever 11 connected to point A, and a pressure signal fed through a diaphragm 50, lever 52 and lever 58 which is connected to point B. A lever 14 on the lever 58 is adjustable to vary the proportion of the pressure signal from zero. The lever 13 carries a changeover lever 21 movable from the full line position to the dotted line position to provide direct or reverse actuation of a lever 22 through a cam 21a, which abuts cams 24 or 25. Movement of the lever 22 is imparted to a bearing point 26 of triangular lever 27 connected to a fixed pivot 28. The lever 27 has a centrally positioned bearing lug 31 which abuts a hinged pilot valve 32 controlling leakage from a nozzle 34. Feedback from the relay may be provided through levers 39 and 43, the latter acting at 48<SP>1</SP> on the lever 27, the amount of the feedback signal being adjusted by a lever 37 from zero. The pneumatic relay comprises a fluid supply 47, Fig. 7, fed to a chamber 72 and past a valve 77 to a signal outlet- 40. A valve member 82 carried by diaphragms 81, 90 co-operates with the stem 86 of valve 77 to control flow from the chamber 78 to exhaust. The valve 82 and hence valve 77 is positioned by the pressure in the chamber 91 which is controlled by the pilot valve 32, whereby the relay output signal is proportional to the input signal to the lever system.
