Title: Improvements in and relating to the construction of buildings
IPC: E04B1/344
Filed: 1945-05-10
Abstract: 593,589. Extensible buildings. McDONALD, J. R. H. May 10, 1945, No. 11765. [Class 20(i)] [Also in Groups XXII and XXV] Buildings have one or more of the walls or the roof or sections thereof hingedly supported in such a manner that it or they may be rotated about the hinges to form part of the wall and/or roof of an extension of the building. Roof sections a, b are hinged at a<1>, b<1> so that they may be turned to form the side walls of an upper storey, the original truss members c<1> (if any) then forming part of the ceiling. Rafters d of the roof and adjacent joists e of the ceiling may be hinged together by a pin passing through bushes in these members (see Group XXII). In a modification of this joint the bushes and hinge pin protrude from the rafters and joists and have aligned holes diametrically through them to take tapered pins. These pins bear on washers and force them hard against the sides of the rafters and joists. Ordinary nuts and bolts may serve as hinges. When turned into the vertical position the lower ends of the rafters may rest on blocks q attached to the wall head immediately below, and to ensure that these blocks take the load, the bushes in the rafters may be slightly elliptical, the major axis then being vertical. The roof may form, on extension of the building, a mansard roof for an attic or it may be curved to give a Flemish-barn outline. Eaves pieces, fascia and roof ridge may be detachable and removable to a new position. Further provision for extension may be made by having wall sections, vertically hinged in a similar manner to the roof sections.

Title: Improvements in change-speed gearing
IPC: F16H3/08
Filed: 1929-04-16
Abstract: 310,036. Soc. Anon. des Anciens Etablissements Panhard et Levassor. April 21, 1928, [Convention date]. Variable-speed gearing comprises gears 11, 30 adapted to be clutched to shafts 3, 24 respectively bv sleeves such as 29 provided with projecting clutch fingers 28. Gear 30 is loose and is connected by a sleeve to a dog clutch ring 31. The fingers 28 have a gap which in the position shown clear the clutch 31 so as to leave gear 30 loose. When sleeve 29 is slid either way, the. fingers engage clutch 31 so as to entrain gear 30. A similar finger and ring arrangement is shown at 14, 13. The Specification as open to inspection under Sect. 91 (3) (a) describes the four-speed gear shown which has three pairs of gears. There is a direct clutch drive and a first reduced speed through train 11, 30, 27, 15. Between the latter speed and the low speed through train 11, 30, 23, 20 there is a second reduced speed through train 15, 27, 23, 20. The middle gear 15 fast on an intermediate shaft 3 can be clutched either to driving-shaft 1, or to driven shaft 2, or to both simultaneously. Gear 30 is loose on and clutchable to countershaft 24. The second reduced speed is obtained by clutching gear 15 to shaft 1, and gear 20 to shaft 2. The latter speed is produced by a sleeve. 18 with dogs 22 passing through a spur gear 32 fast on shaft 2 and adapted to engage holes 21 in loose gear 20. The sleeve 18 when moved to the left engages splines 17 on the hub of gear 15 for connecting that gear to shaft 2. Reversed driving is effected through an idler, not shown, caused to connect the gear 32 to the gear 23 by movement to the right of striking- ring 29 which carries the dogs 28. An arrangement for obtaining eight forward speeds from four pairs of gears is set out schematically. This subject-matter does not appear in the Specification as accepted.

Filed: 1938-04-19
Abstract: 513,557. Controlling motor vehicles. AUTO UNION AKT.-GES. April 19, 1938, No. 11795. Convention date, April 15, 1937. [Class 79 (v)] [Also in Group XXIV] A combined accelerater and gear change pedal 2, controlling both the engine throttle and a clutch effecting engagement of a mechanical gear unit associated with a hydraulic transmission, has its range of movement divided into two stages : between positions I and II during which it is connected with the throttle, and between positions II and III during which the clutch is actuated whilst the throttle is closed and remains closed throughout the return movement of the pedal to its initial position I. The invention is of particular application for the joint control of the throttle of a motor vehicle and a clutch for connecting and disconnecting a mechanical overdrive gear to and from a hydraulic torque converter. The pedal rocks on a pivot 1 and has an arm 4 having a lost-motion in-and-slot connection 8. 9 with the clutch actuating mechanism. A second arm 5 on the pedal has a knuckle-jointed pawl 17 engagable with a bell-crank 10 connected with the throttle. During movement of the pedal between positions 1 and 11 the pawl 17 rocks the bell-crank 10 and progressively opens the throttle, the pin 8 working idly in slot 9. Between positions II and III the pin-andslot connection becomes operative to actuate the clutch and introduce the overdrive gear, pawl 17 having slipped past the bell-crank 10 at positior II so that the throttle is disengaged and closed by a spring. Upon return movement of the pedal to position 1 pawl 17 re-engages the bellcrank 10 so that the throttle can be opened again by depressing the pedal between positions I and II, the overdrive gear remaining operative until the pedal is again moved to position III when the clutch is operated to disconnect it.

Abstract: 781,430. Gas turbine plant. RUSTON & HORNSBY, Ltd. April 25, 1955 [April 24, 1954], No. 11886/54. Class 110 (3). A gas turbine plant in which powdered fuel is fed to a combustion chamber by fluidization which occurs in two stages comprising a fluidizing column working at atmospheric pressure which feeds fuel to a second fluidizing column working at a pressure appropriate to the combustion chamber pressure has the fuel supply to the atmospheric fluidizing column controlled by a device having a piston sliding in a cylinder, the setting of the piston being controlled by a diaphragm which is responsive to the static pressure difference between the dilute phase and the bottom of the bed in the atmospheric column. The dilute phase is stated to be the space above a fluidized bed in which there are solids entrained in the upflowing gas. The invention is described with reference to the gas turbine plant described in Specification 781,427. The static pressures referred to are connected to unions 56 on opposite sides of a diaphragm chamber. The diaphragm 58 controls the buildup of pressure in a cylinder 59 and hence the setting of the piston 60. The piston 60 is connected to adjustable blades which control the rate of delivery of fuel to the atmospheric columns. Specifications 781,428, 781,429 and 781,431 also are referred to.

Filed: 1921-04-26
Abstract: 183,574. Bates, A., Minett, W. T., and British United Shoe Machinery Co., Ltd. April 26, 1921. Lasting and pulling-over.- In a pulling-over or pulling- over and lasting machine, means are provided to give warning of an abnormality (e.g. if no upper is gripped, or if any one gripper has lost its grip) in the state of any of a plurality of upper tensioning devices, and to prevent a later operation (e.g. tack-insertion) being carried out with such abnormality continuing. In the construction shown applied to a machine of the kind described in Specification 150,424, means for preventing the insertion of tacks are operated through a rod 3 adapted to be moved into line with a block 6 on the cam slide bar 2 (referred to as 252 in Specification 145,851) when any one of the gripper updraw levers 13 is not in correct tensioning position. Each lever 13 has pivoted to its rear end a link 14 which is slotted at 15 to receive one pin 12 which passes through all the links 14. The pin 12 is carried by one arm 11 of a bell-crank lever, loosely mounted on a shaft 10, the other arm 9 of which is yieldingly connected by a rod 7 to the rod 3. The rod 3 is connected through members 1, 4 fast on a rockshaft 5 to a link 17, the other end of which is pivoted to an arm 18 fast on the shaft 10. A second arm 19 fast on the shaft 10 is pivoted to a link 20 which operates, through bell-crank levers 22, 26 and a link 25, to move a recess 31 on a sliding bar 30 into the path of a lip 32 on the tack pot 33. A third arm 34 fast on the shaft 10 is pivoted to a link 35 the other end of which is pivoted to one arm 36 of a bell-crank lever fixed on one end of a shaft 37 having a bearing in a boss 38 formed on one of the blocks 39 about which the front tacker arm 40 swings. The other arm 41 of the bell-crank lever is connected bv a link 42 to an arm 43 mounted on a shaft 44 in the other block 45. The shaft 37 has on its opposite end a cam 46 and the shaft 44 carries two similar cams. The cams are embraced by the forked ends of slide rods 47 the other ends of which are arranged to enter notches 49 in the driver bars 50 when the shafts 37, 44 are rotated by the rod 35, preventing actuation of the driver bars. The lip 32 and recess 31 maintain the slide rods 30, 47 in operative position against the action of a spring attached to the arm 19 until the lip 32 is withdrawn on the recturn movement of the tack pot driving. mechanism. By inverting the action of the mechanism described it can be used to ensure that no tacks are separated or driven unless the grippers have moved far enough in tensioning the upper to be well clear of the feather of the insole in their in-closing movement.
