Title: Improvements in or relating to locks or the like
Inventor: HOBBS DUDLEY EDWIN
IPC: E05B65/32
Filed: 1948-08-11
Abstract: 649,126. Door latches. BRISTOL AEROPLANE CO., Ltd. Aug. 11, 1948, No. 21230. [Class 44] In a door latch of the kind having a swinging latch member 31, Fig. 2, for co-operation with a keeper 14, and a catch 39 adapted to retain the latch in the locking position, a bell crank lever 41, arranged to be actuated by out side operating means to release the catch 39, is carried on a slidable bar 42 adapted to be moved by inside operating means to cause the bell-crank lever to release the catch 39 and by further means to render both operating means ineffective. A spring 37, fixed at 38 to the catch and at 35 to the latch member, tends to turn the catch to the latch retaining position and to turn the latch to disengage the keeper and provide an initial opening of the door. The outside operating means comprise a press-button 15 having a spring loaded plunger 24 carrying a radial arm 29 at the inner end and a flexible diaphragm 26 at the outer. When the button is pressed, the arm 29 engages an arm of the bell-crank lever 41, turning it to rotate the catch. The bar is reciprocably carried on a link 43 pivoted to the catch pivot 40 and on a lever 52 pivoted to a bracket 53. A rod 17 pivoted to the other end of the lever 52 is displaced to the right by an inside press-button acting through a bellcrank lever. This movement carries the lever 41 against the short arm of the catch 39 and causes it to release the latch. The rod 17 is broken in its length and a mechanism is interposed to connect or disconnect the ends 17a, 17b, Fig. 6. A pusher 71 71 pivoted at 72 to the end 17a normally engages a pin 67 on the end 17b to transmit the releasing movement from the inside button. The pusher may be lifted out of engagement by a handle 58 carrying a cam 59 engaging a pin 70 on the pusher, thereby rendering the inside button inoperative. When the pin 67 is thus released the end 17b is drawn to the left by springs 68. This causes the bar 42, Fig. 2, to move to the right and place the lever 41 out of the path of the press-button arm 29 thereby rendering the outside press-button inoperative. The rod parts are re-connected by turning the handle 58, Fig. 6, in the opposite direction, the surface 66 of the cam engaging the pin 67 to displace the rod to its normal position and allow the pusher to return to the normal position under the action of :spring 73. The handle is retained in either position by a spring detent 62 engaging in either of a pair of notches 61 in a disc 60. Another connecting mechanism is described slightly different in construction to that shown in Fig. 6.

Filed: 1919-09-01
Abstract: 141,317. Soc. des Etablissements E. Feuillette. March 29, 1919, [Convention date]. Deflectable axle-ends; steering-gear and steering.-In a combined motor and steering unit, more particularly applicable for the operation of agricultural tractors, in which the motors are displaced angularly with the steering wheels which they drive, each of the motors and the wheel which it drives are displaced angularly about a vertical axis passing through two fixed points of the frame of the vehicle, the vertical axis being the axis of the motor cylinder. Two motor units 1 may be employed symmetrically disposed about the axis of the control shaft 9, as shown in Fig. 2, or a single motor unit may be used in conjunction with an idle wheel on the axle of the driving wheel, or four motor units may be employed to form a tractor with an equal number of driving and steering wheels. In the arrangement shown in Fig. 2, the motor casing 16 is integral with a sleeve 3 which extends through the driving wheel 4 and forms a bearing for the extension 2 of the crank-shaft. The steering movement is controlled by the shaft 9 which has a pinion 14 engaging toothed segments 15 extending from the motor casings. The shaft 9 is operated by the steering-wheel shaft 12 through worm gearing 11, 10, housed in a casing 8.

Abstract: 823,529. Controlling aircraft. FAIREY AVIATION CO. Ltd. July 12, 1956 [July 25, 1955], No. 21477/55. Class 4. A braking flap 10 is mounted on the rear end of an aircraft fuselage 11 by means of links 12 and 13 respectively pivoted to the flap at 14 and 16 and to the fuselage at 15 and 17. The pivot 14 provides also a connection for the ram of a jack 20 which is secured to the aircraft at 21. The flap, which for aerodynamic reasons has to be extended to the position shown by chain dotted lines by rearward and outward movement, may by this mechanism be retracted to the position shown in full lines clear of the outlet 23 of a jet pipe. There may be flaps on opposite sides of the fuselage 11 or a plurality of flaps may be arranged around the rear end of the fuselage in petal formation.

Title: Improvements in and relating to washing machines
IPC: D06F39/02
Filed: 1945-08-23
Abstract: 636,104. Washing-machines. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 23, 1945, No. 21556. Convention date, Aug. 25, 1944. [Class 138 (ii)] A washing-machine performs a series of operations in timed sequence, including a number of operations during which water is supplied to the machine, one of which operations is an intermediate washing operation ; tepid and hot water are supplied through separate valvecontrolled passages, hot water being supplied only during the intermediate operation; and a soap box is arranged in the hot water passage, which box can be loaded prior to the commencement of the sequence with water-conditioning compound to be flushed out by the hot water during the intermediate operation. As shown, the machine is of the kind described in Specification 625,324 and comprises an outer casing 1 in which is located a spinner basket 2 with centrifugal discharge holes 3 and an agitator 5. A sealed casing 4 contains mechanism for driving the agitator and rotating the basket. During washing, the basket is filled to overflowing by water from the base of the casing circulated by a pump 6 through a pipe outlet 9. Water is supplied to the machine through a pair of solenoid-operated valves 11, 12, under the over-riding control of a float-valve 14 which cuts off supply when the water in the casing reaches the desired level. During most washing operations, water at high temperature is unnecessary and tepid water is supplied through a valve 11 and a nozzle 15. Water at a higher temperature is obtained through valve 12 which discharges via a tangential pipe 16 into a soap box 17 creating a vortex within the box. The particles of soap are flushed out of the box through a pipe 18 and are dissolved as they pass through the pump 6, any undissolved particles being trapped in the filter 10 on the spinner basket.

[Class 122 (i)] In a piston packing, one or more grooves respectively are bounded by two non-expansible, non-split parts movable longitudinally relative to one another primarily under fluidpressure so as to clamp the piston-ring when the cylinder pressures are high. The head 1 and skirt 2 are connected by a nut 3, Fig. 1. The lower lateral wall 7 of the groove is carried by the skirt 2 ; the upper wall 8 and base 9 are carried by a closed, angle-like, stainlesssteel ring 12 with a cylindrical element 10 which freely surrounds the part 4 of the head 1 and extends into a recess beneath the groove. The ring 12, 10 is relatively displaceable with respect to the skirt 2 by fluid pressure. A piston-head flange 13 limits the play. Alternatively, a square or trapezoidal thread is arranged on the lower inner face of the part 10 and on the exterior face of the head 1. Slight longitudinal play is provided. A bayonet joint connection may be used. The external contour of the ring 12 follows that of the head 1. The head, skirt, and collar 4 may be in one piece. The ring 12 may be in two parts, Fig. 3, the wall 8 is on a part 14 which is shaped to fit beneath a flange 15 on the part 12. Packing 16 is arranged between the ring 12 and the head 1. Passages 18 in the flange 10 permit access of gases to effect scavenging of deposits.
