Title: Improvements in and relating to lever apparatus adapted for braking and for other purposes
IPC: F16D65/28
Filed: 1921-05-09
Abstract: 163,049. Siemens-Schuckertwerke Ges. May 8, 1920, [Convention date]. Prssses, mechanical. - In pressing-apparatus such as for applying brakes, of the kind comprising a lever the fulcrum of which is changed during the operation of the apparatus to vary the mechanical advantage thereof, the fulcra are provided by cataracts or dashpots which offer resistance successively. With the brake mechanism shown, when the application weight 3 is released by the catch 4, the valve 57 of the cataract 56 is at first seated so that this cataract supports the lever which turns about the pivot 55, the piston of the cataract 5 being provided with a non-return valve 31 to allow of this movement. .The brake blocks are thus quickly brought to the engaging position. The reaction on the pivot 55 when the blocks are engaged is insufficient however to hold the valve 57 seated against the action of the spring 57<1> so that the support for the lever is transferred to the pivot 8 on the cataract 5, the non-return valve 31 closing at this stage. The mechanical advantage is thus increased.

Abstract: 554,686. Carburetters. CHANDLEREVANS CORPORATION. Oct. 14, 1941, No. 13220. Convention date, Oct. 15, 1940. [Class 7 (iii)] Fuel delivered by a pump 2 to a metering- orifice 3 and nozzle 4 is controlled in accordance with the air flow through the intake 1 by means of a diaphragm 17, and in accordance with the fuel flow by means of diaphragms 21, 61, 95. Adjustment is further made in accordance with altitude by a sylphon 26, and in accordance with air temperature by a sealed bulb 28. An annular passage 15 connected by orifices 14 to the intake is in communication with the chamber A by ports 33 and passages 45, 44, 43, while the other side B of the diaphragm 17 is connected by passages 46, 47, 48 to another annular passage 13 having orifices 12 opening into the Venturi 10. A restricted passage 49 connects the chambers A and B. The pump 2 receives fuel at 56 from a tank 60 and delivers it at 59, and its output is adjusted by the diaphragm 61 moving the casing 53 of the rotor about a pivot 54. The pump delivery 59 is connected to the underside of the diaphragm 61, and through a restriction 69 with the upper side and also with a conduit 37a leading by a passage 37 to a chamber C to the left of the diaphragm 21. Fuel pressure is thus built up in the conduit 37 until sufficient to move the diaphragm 21 to the right and open a passage 40 leading to a relief vent 42. The fuel delivery passes into a tank 72 and from there to the metering-jet 3 by one or both of passages 82, 83, according to the position of a valve 8 adjusted by hand according to the richness of mixture desired. The suction at the jet 4 is prevented from varying the fuel supply, by means of a valve 101 controlled by the diaphragm 95, which is acted on by the fuel pressure and at the opposite side by the air pressure in the intake communicated through a passage 100. The altitude and temperature changes adjust a valve 30 controlling the ports 33. Throttles 5 are arranged as shown in front of the jet 4, and are adjusted together with a valve 9 controlling the fuel for idling. In a modification, the diaphragm 61 adjusts a bye-pass in the pump 2. This pump may be of the form described in Specification 544,375, [Group XXX].

Title: Improvements in or relating to landing gear for aircraft
IPC: B64C25/14
Filed: 1942-09-25
Abstract: 560,604. Aircraft landing gear. BENDIX AVIATION CORPORATION. Sept. 25, 1942, No. 13529. Convention date, Sept. 26, 1941. [Class 4] The hydraulic connections for the retraction motor of a landing wheel strut extend through the pivot of the motor on the aircraft whereby flexible conduits are avoided. A locking pin for the strut, operated by initial retraction movement of the motor and manually operated means for locking the wheel against castoring movement are also described. The strut comprises a shock-absorber cylinder 18 pivoted at 16 to the aircraft. The forked end 62 of the piston rod 32 of the retraction motor 34 which is pivoted to the aircraft at 36 has a pin 60 that extends through slots 64, 58 in a housing 54 secured to the cylinder 18 and in a locking pin 30 slidable in the housing. With the strut in the extended position shown, the upper end of the pin 30 is engaged in a fixed recess by a spring 56 to lock the strut in position. Initial downward movement of the piston rod first withdraws the pin 30 from the recess and when the pin 60'reaches the lower end of the slot 64, the strut is turned into the horizontal retracted position. The wheel fork 26 is carried by a cylinder 20 that telescopes into the cylinder 18 and contains shock-absorber liquid which is forced through an orifice 23 in the base of a perforated cylinder 21 fixed at its upper end 19 to the cylinder 18. Torque arms 22, 24 are pivoted together, to the wheel fork 26 and to a ring 46 rotatable on the cylinder 18. When it is desired to prevent castoring movement of the wheel, a pin 48 which can be withdrawn by a cable 38, is engaged with the ring 46 as shown. To avoid flexible conduits for the hydraulic supply to the double-acting motor 34, the pivot 36 upon which the motor is mounted is formed with passages 70, 78 that are connected by radial ports 72, 80 respectively to the cylinder chamber below the piston 33 and to a pipe 35 leading to the upper cylinder-chamber. Pipes 76, 86 connect the passages 70, 78 to the control valve.

Filed: 1957-04-30
Abstract: 804,710. Carburetters. DAIMLER-BENZ, A. G. April 30, 1957 '[April 30, 1956], No. 13760/57. Class 7(3) In a carburetter in which each passage 2, 3 has its own fuel feed device and the second throttle valve 7 does not open until the first throttle valve 5 has partially opened, a pin 11 on a lever 12 which operates the second throttle valve, projecting into the path of angularly spaced arms 15, 16 on the operating lever of the first throttle valve, a tension spring 17 is articulatedly connected between the operating levers of the two throttle valves the arrangement being such that the line of tension of the spring approaches the centre of rotation of each of the operating levers as the latter are turned in sequence for opening the respective throttle valves whereby the spring is operative with a decreasing effective leverage on the second throttle valve as the latter opens. The throttle valve 5 opens the passage 2 until after traversing the angle 19 the striker arm 15 encounters the pin 11 so that on further movement the throttle valve 7 is opened. Only in the event of breakage of the spring does the arm 16 bring the throttle 7 into closed position. The arrangement of the spring 17 is such that the torque applied to the shaft 6 of the throttle 7 is substantially constant over the entireopening movement of the throttle 7. This is advantageous particularly when controlling a plurality of carburetters.
