Title: Improvements in or relating to a windshield cleaner
IPC: B60S1/16
Filed: 1953-09-09
Abstract: 733,972. Controlling friction clutches. TRICO PRODUCTS CORPORATION. Sept. 9,1953 [Sept. 9, 1952], No. 24970/53. Class 80 (2). A windshield cleaner comprises a wiper, a transmission for the wiper including a speedresponsive clutch having a driving member 32, Fig. 2, driven clutch shoe means 36- 38 resiliently urged to frictionally engage the driving member, a rotatable shaft 62 having limited axial movement, and means 44 operable by the axial movement of the shaft to move the shoe means radially out of contact with the driving member, the means 44 operatively connecting the shaft to the shoe means. The driving clutch member 32 is connected to the driven shaft 24 of the motor vehicle generator, and is formed with oil ducts 33. The means 44 comprise prongs, inclined to the axis of the clutch and engaging slots 40 in the shoes, fast for rotation and axial movement with the shaft 62, which is flexible and transmits drive through mechanism to the wiper arms. Movement of the shaft 62 and prongs 44 to the left of Fig. 2 against the force of a spring 54 moves the clutch shoes 36-38 radially outwards against the force of a surrounding garter spring 39 to disengage the clutch. The clutch shoes are acted upon by centrifugal force, when the clutch is engaged and rotating, in such a way as to tend to disengage them from the driving member, the effect being to allow slip when the speed of rotation of the driving member exceeds a certain value, whereby the speed of rotation of the driven shaft is constant. In a modification, Fig. 9 (not shown), the clutch shoes are directly engaged by bell-crank levers, pivoted on axial movement of the driven shaft to move the clutch shoes out of engagement with the driving member. The shaft 62 is connected to a worm 79, Figs. 5, 6, meshing a worm gear 70 connected by links 13, 15 &c. to the wiper blades which are thereby oscillated. A plate 105 can be moved downwardly first to compress a spring 108 and then release a catch 99, to move the shaft 62 axially and disengage the clutch, the spring 108 abutting a sleeve 91 fast with the shaft; downward movement of the plate 105 is caused by moving a link 109, pivoted to it at 111, so that its end is engaged by a pin 116 on the gear 70, rotation of which then compresses the spring 108 &c. The link 109 is controlled by manually rotating a pivoted plate 112 having a pin 113 engaging a slot therein, the parts being so arranged that the clutch is disengaged when the wipers are in the parked position. To re-engage the clutch, the plate 112 is turned to move the link 109 out of the path of the pin 116 and pull the sleeve 91 upwardly of Fig. 6 to restore the position shown. In a modification, Figs. 7, 8 (not shown), the pivoted link acts directly on a sleeve connected for axial movement with the shaft 62 but not rotating therewith.

Abstract: 1,012,387. Master cylinders. WAGNER ELECTRIC CORPORATION. June 24, 1963 [Oct. 31, 1962], No. 24985/63. Heading F2F. A fluid pressure generating device for a vehicle comprises a housing 28 having first and second fluid pressure generating portions 36, 37, a pressure fluid reservoir 30 including first and second separated sump chambers 65, 66 for supplying fluid to the portions 36, 37, a main supply portion 67 in the reservoir and normally providing pressure fluid transfer between the chambers 65, 66, vertical wall means dividing the reservoir laterally to define the sump chambers, and means 70, 71 projecting from the vertical wall means for limiting to a predetermined minimum the amount of pressure fluid retained in one of the chambers 65, 66 due to pressure fluid transfer between the chambers in response to changes of velocity of the vehicle. As shown, an operator applied force on the pushrod 33 moves the piston 31 to the right to displace pressure fluid from the first chamber 36 through 15 to rear brakes 18, 19. The fluid pressure created in the first chamber 36 is effective on the second piston 35 to move it to the right to displace pressure fluid from the second chamber 37 through the outlet 21 to front brakes 24, 25. On release of the brakes springs 42, 48 return the pistons to their original positions. In the event of a leak in the rear brake system the extension 38 of the first piston will slide in sleeve 39 until it abuts face 41 when it will actuate the second piston to apply the front brakes. Similarly in the event of a leak in the front brake system the second piston will move until extension 52 contacts surface 53 when the piston 31 can then move to pressurize the fluid in the chamber 36. The two sump chambers 65, 66 are separated by two walls 64 formed with a table 69 which with restrictions in the side walls of the reservoir forms a passage 68 providing communication between the two chambers 65, 66. In modifications a single separative wall with a table, the side walls being formed flat, is provided or a separating wall extending from the top to the bottom of the reservoir and having a tubular member extending therethrough to provide communication between the two sump chambers is provided.
