Abstract: 853,475. Windscreen cleaners. TRICO PRODUCTS CORPORATION. Dec. 27, 1956 [Dec. 27, 1955], No. 39331/56. Class 138(1). A windscreen wiper arm, particularly for use on panoramic windscreens, is pivoted for universal movement under the influence of cams which impart a complex rocking motion during the oscillation of the arm. As shown, the arm comprises an inner section 8 mounted on operating shaft 7 and an outer wiper-carrying section 11 which has a channelled cam 13, the two sections being interconnected by clevis 12 and stub shaft 15. When the arm moves in accordance with the contour of the windscreen, laterally offset lobes 18, 19 rotate about axis 20 and react upon shelf 17 to impart a rocking motion to section 11 about shaft 15 and thus hold the wiper normal to the screen. Tension spring 23 connects sections 8, 11 and applies wiping pressure to the wiping blade. In two modifications (a) the inner section may be formed with a cam for co-operating with a supporting shelf on the outer section, and (b) the supporting shelf may overly the cam lobes, Figs. 6-8 (not shown).

Title: Fuel injection pump
IPC: F02M59/00
Filed: 1957-12-23
Abstract: 830,095. Starting fuel injection engines; regulating. SCHAFER, G., and SCHAFER, O., [trading as KUGELFISCHER G. SCHAFER & CO.]. Dec. 23, 1957 [Sept. 19, 1957], No. 39790/57. Classes 7(3) and 7(6) [Also in Groups XXVIII and XXXIV] In a fuel injection pump in which the return stroke of the plunger 28 is controlled by a lever 26 pivoted at 27, the other end of the lever is controlled by an adjustable tappet 40 engaging a cam 41 having a three dimensional curve and being axially slidable under the control of a lever 45 connected to the engine throttle and partially rotatable in response to the speed of the engine. In the two cylinder pump shown the plungers are actuated by tappets 22 engaging cams 24 on a driven cam shaft 10. The cam 41 is mounted on a shaft 42 parallel to the cam shaft 10 and at one end is connected through an energy storing spring housing 50 by a driving band 46 to a further parallel shaft 47 carrying permanent magnets and surrounded by a short circuited runner 48 driven through gears 51, 52 from the cam shaft 10. The minimum stroke of the pump is set by means of a screw 53 engaging the end face 54 on the cam 41 the face 54 being helical in order to close the engine throttle further than the idling setting on over-run. The pivot 27 for the lever 26 is eccentrically mounted on a shaft 55 connected to a lever 12 whereby additional control of fuel for starting and warming up is supplied; this control may also be used for abnormal conditions of altitude and temperature. Instead of the angular movement of the cam 41 being sensitive to speed the Specification states that it may be controlled by density. A worm 56 (Fig. 4) on the shaft 10 engages a worm wheel 57, having a cam face 61, secured to a plunger 58. The face 61 is more or less engageable with a pin 60 (Fig. 1) to reciprocate the plunger 58, under the control of a stop 64 which engages a lever 65 pivoted at one end at 66 and at the other engaging a cam surface 68 on the tappet 40 whereby the stroke of the plunger 58 varies with the stroke of the injection pump. The plunger 58 has a control groove 59 and draws lubricating oil from a port 62 and delivers it to outlets 18, 19 which supply lubricating oil to the engine directly or to the combustion air; the supply of lubricating oil is thus proportional to the fuel injected. The initial setting of the lubricating pump may be adjusted by moving the end of the lever 65 along the surface 68.
