Title: Improvements in or relating to water heaters
IPC: F24H1/18
Filed: 1936-06-22
Abstract: 477,298. Liquid-fuel burners. KNUPFFER, M. June 24, 1936, No. 17561. [Class 75 (i)] [Also in Group XXXV] The atomizing nozzle 7 of a liquid-fuel burner is mounted in an extension 6 or a member attached in heat conducting relation to a fuel preheating chamber 1, the extension or member being of large mass in proportion to its heat radiating surface so as to maintain the fuel near the nozzle sufficiently fluid to ensure atomization by the air blast when the fan motor is started. The preheating chamber contains a fuel strainer and two thermostats 31, one controlling the supply of current to an immersion heater 29 and the other the current to the motor driving the fuel pump and fan. The fan is arranged in a casing 8a and delivers air past a pivoted light aluminium damper 11 to a draught tube 4 which is fitted adjacent the nozzle 7 with a cone 17 formed with airswirling vanes 22, a flame inspection window, and ignition electrodes 21. The draught tube and cone are slotted to allow the draught tube to slide rearwardly in guides 37 on the housing 8a to allow of access to the nozzle 7. A tubular filling piece 18 for the slots in the draught tube and cone is attached to the extension 6. A valve 10 controlling the fuel passage in the nozzle 7 is pressed by a light spring into contact with a spindle 27 attached to a spring-pressed diaphragm arranged in a housing 14 carried by a tube 3 which is secured to the extension 6. The tube 3 communicates with the fuel passage 9 in the extension 6 so that the valve 10 only opens when the fuel pressure on the diaphragm overcomes the resistance of the spring 26. The chamber 1 may be partially or wholly surrounded by asbestos lagging 35 covered with aluminium sheeting. In a modification, a single thermostat arranged in a tubular strainer operates in succession two mercury switches, the first operated starting the fuel pump and fan motor and the second opening the circuit of the immersion heater. Specification 479,019, [Group VII], is referred to.

Filed: 1935-11-18
Abstract: 468,062. Controlling aircraft. HEINKEL, E. Nov. 18, 1935, No. 31962. Convention date, Dec. 1, 1934. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 18, 1936.] [Class 4] Relates to automatic means for limiting the maximum accelerations to which an aeroplane structure can be subjected by use of the elevator controls, such means being of the type in which the movement of resiliently mounted or resiliently constrained masses is utilized to control the elevator setting. It is stated that the vertical acceleration of the centre of gravity of an aeroplane as the result of elevator application reaches a peak value substantially later than does the angular acceleration, according to the invention therefore the controlling mass if of the type having resiliently controlled linear movement is mounted as far as possible from the centre of gravity or if of the type mounted for resiliently controlled rotary movement about a fixed axis is disposed at or near the centre of gravity of the aeroplane. In one form, Figs. 3 and 4, a mass 31 is slidably mounted in a casing 32 arranged with its axis vertical at the tail of the aeroplane. Movement of the mass is restrained by springs 30, 30<1>. Mass 31 is formed with a projection carrying contact members 33, 35 connected to the terminals of battery 34. Contact 33 is adapted to slide along one or other of two resistances 41, 41<1> connected to the terminals of a reversible electric motor 40 and contact 35 is adapted to engage one or other of two contact pieces 43, 43<1> also connected to the motor. The motor may be connected to the elevator or to an auxiliary elevator 60 by cable and rack and pinion mechanism as shown in Fig. 6. In another form, Fig. 5, a mass 63 is rotatably mounted on a shaft 65 and is coupled thereto by a spring 64, the mass being placed at or near the centre of gravity of the aeroplane. Mass 63 is coupled by a rod 66 either directly or through a relay to an elevator trimming tab.

Title: An improved differential gear for motor driven vehicles
IPC: F16H48/30
Filed: 1925-12-21
Abstract: 268,017. Emmitt, C. G. Dec. 21, 1925. Balance or differential gearing is adapted to be locked solid when a car fitted with the invention is running straight, and to be freed from the steering-gear when a curve is to be taken. The locking is effected by plate clutches T, Fig. 1, making connection with holders 0, which can slide radially but not turn in their sockets in the planet-carrier M, which may be driven as usual by a worm Q. The holders O are normally held thrust outwards by springs H so as to lock the clutches and prevent epicyclic action. A slidable cone G bears upon the holders 0 through steel balls R. When a cam frame D, Fig. 2, is moved through suitable connections from the steering wheel, the cone G is thrust to the left of Fig. 1, and the differential is set free.

Title: Improvements in jib cranes and the like
IPC: B66C23/82
Filed: 1929-10-24
Abstract: 340,670. Jib cranes. REID, J., 9, Beechwood Gardens, Calder Road, Mossend, Lanarkshire. Oct. 24, 1929, No. 32290. [Class 78 (iv).] A safety device consists of an auxiliary tie rope e<2> reeved round two series of pulleys f<3>, g and anchored at its end f<7>, the upper series f <3> being fixed and the lower series g being adapted in normal operation to move to or from the fixed series f <3> with the descent or ascent of the jib, in combination with automatically acting means whereby (1) if the main jib tie f breaks or (2) if the luffing winch gets out of control, or (3) if an attempt is made to lower the jib before it has been sufficiently slewed, the lower block of pulleys g is prevented from approaching the fixed block f<3>, whereby the jib is held on the auxiliary tie rope. The spindle of the pulleys g is slidable in slots in side plates f and carries a pair of pawls g4 which are normally retained in the position shown in Fig. 3 by the vertical rod j<1>. In any of the three above-mentioned contingencies the rod l is automatically urged upwards thus allowing the rod jl to fall outwards and the pawls g<4> to swing by gravity to engage the racks in the plate h which slides by slots h<1> on pins h<2> in the side plates f<5>. The pulleys g and the pawls g<4> rise, carrying the plate h with them until the pins h<2> reach the ends of the slots h<1>, when further movement is prevented. Almost at the same moment the links i, i<1> apply a brake to one of the pulleys f<3>. To operate the safety device, (1) if the main jib tie breaks, the pulley n<1> in the heavy casing n<2> pivoted below its centre of gravity falls and the plate n<4> strikes the lug n upward (2) if the luffing winch rotates too quickly a governor displaces the lever m<4>, allowing the weight m<3> to fall and the lever m<1> to strike the lug m ; and (3) if the jib is lowered before being sufficiently slewed a lever p<8> at the lower end of the jib by engagement with a raised quadrant on the base of the crane releases jaws which hold the rope p, allowing the weight o<3> to fall and the lever o<2> to strike the lug o.

Filed: 1949-12-16
Abstract: 668,578. Spray carburetters. CARTER CARBURETOR CORPORATION. Dec. 16, 1949, No. 32376/49. Class 7(iii) In an automatic choke device a fast idle cam 36 freely mounted on the choke shaft 13 is connected to a disc 24 fixed to the shaft 13 through a spring 40 which allows lost motion in both directions to permit the choke valve to close and open freely irrespective of the position of the cam 36. The choke valve 12 is controlled by a thermostat 21 and a suction-actuated piston 27 connected to the disc 24 and the throttle valve control arm 16 is connected by a link 51 to a sliding member 48 provided with fingers 50, 49 co-operating with a finger 47 on a lever 45 which has a finger 46 co-operating with the cam 36. With the choke valve closed for cold-starting, the cam 36 holds lever 45 in a position in which the finger 47 prevents the throttle valve closing beyond the fast idle position. When the engine fires, the choke valve 12 slowly opens and the disc 24 rotates clockwise in which position the finger 46 engages in a notch 37 to permit the throttle valve to close to the normal idling position. If the engine is stopped with the finger 46 engaging in the notch 37, the resilient connection between the disc 24 and cam 36 permits the thermostat to close the choke valve. Flooding of the intake manifold during starting is relieved by opening the throttle valve to wide open position, when the finger 50 rotates the lever 45 to cause an arm 56 thereof to contact a finger 55 on the disc 24 and pull the choke valve partially open. Specifications 472,090 and 638,377 are referred to.

Abstract: 821,136. Electromagnetic switches. BURGESS, V. E. Feb. 12, 1957 [Nov. 12, 1955], No. 32406/55. Class 38 (5). A D.C. operated make-and-break switch and transformer for electrifying fencing comprises a magnetic core 1 with an air gap 3 and primary and secondary coils 2. An armature 4 carrying an insulated contact 8 is pivoted on the core 1 at 6 and urged to bridge the gap 3 by a rubber pad 11. A balance wheel comprising an aluminium disc 5 is mounted on ball bearings on the pivot 6 and is urged by an adjustable spring 9 to press a contact 7 thereon against the contact 8 and oppose the bias on the armature due to the pad 11, a stop 12 limiting this movement. When a series switch 17 is closed to energize the primary coil through the normally closed contacts 7, 8, the impulse on the armature 4 is imparted to the disc 5 through the contacts so that the disc rotates against the spring bias to open the contacts which close again to repeat the cycle of movement when the disc is returned by the spring 9.

Abstract: 447,961. Brush - making apparatus. EBSER, G., (trading as EBSER MASCHINENFABRIK, G.), Todtnau, Baden, Germany. Nov. 22, 1935, No. 32418. Convention date, Nov. 24, 1934. [Class 19] Bristle feed to a slotted quadrant r, Fig. 2, in conjunction with a filler nozzle 8 is characterized in that each time the quadrant feeds a bunch of bristles to the nozzle the feed box is caused to recede temporarily from the quadrant. In this way, a constant quantity of bristles is ensured as the pressure is always the same during the formation of the tuft. The notched quadrant r is provided at its rear end with a cam u which in conjunction with an abutment 6 on one of the bristle-box members forces the bristle box back an extent commensurate with the amount of bristles withdrawn by the notch a. The bristles are held in a box comprising side members f, g, Fig. 1, and an adjustable bottom plate d, supported in a pivoted frame b on an axis k. The bristles are pressed forwards by an arm h, i secured to the axis k, the lower part of which is connected to a disc l urged forwards by a weight 2 and pulley, Fig. 3. Backward movement is prevented by a spring detent m. To ensure bristles remaining in the slot s as the quadrant moves to the right, a spring finger w, Fig. 2, is provided on the box. To extend the back of the box for fresh material, a curved bar y pivoted at x is provided, having a curved member z to close the box. To fill the box, the arm h is swung to the left and held by a pin 3. The bar y is then opened and material is pressed in with both hands and the part y, z closed with the bar h, i pressing on the bristles. When the cam u acts on the abutment 6, the box slides along the material which is prevented by the plate i from taking part in the return movement. As the material near the edge 9 is first to be used, a cam 7 on the quadrant places stationary material in the vicinity of the edge 9. The bristle box may be adapted to move rectilinearly relatively to the quadrant r instead of as shown.
