Inventor: MCMANUS NORMAN
IPC: B65H75/44
Filed: 1960-07-13
Abstract: 943,416. Hose reels. CHARLES WINN & CO. Ltd. Sept. 25, 1961 [July 13, 1960], No. 24361/60. Heading B8M. A hose reel 10 intended for mounting in a recess, alcove or equivalent position is combined with a guide which is movable automatically into an operative position when a pull is applied to the hose, the guide remaining in the operative position until it is manually returned to a position where the guide lies adjacent to a wall on which the reel is mounted after the hose has been rewound on the drum. As shown, the guide is in the form of a ring 19 mounted on an arm 18 having a sleeve 21 which is rotatable about the hose supply pipe 15 on a collar 23. The sleeve 21 is provided with a downwardly projecting peg which contacts a cam face on the collar 23, Fig. 6. Normally, the peg lies in the recess 25, but when a pull is applied to the hose the peg rides up the ramp 26 and into an arcuate recess which confines the arm 18 to movement through an angle of 35 degrees, each side of a plane at right angles to the wall on which the hose is mounted. A valve 16 controls the supply of water to the hose which is fed through the hollow spindle of the reel. A rubber, plastic or the like disc 28 may be mounted on the nozzle 11.

Title: Improvements in or relating to rotary pumps, compressors, motors, and the like
IPC: F01C3/02
Filed: 1932-09-02
Abstract: 411,465. Rotary engines. MORGAN, W., 106, Pembroke Road, Clifton, Bristol. Sept. 2, 1932, Nos. 24470 and 25019. [Class 110 (ii).] In a rotary engine or pump of the type described in Specification 341,013, having rotary vanes which are " feathered to pass through gaps in the abutment, mechanism is supplied to give an oscillating motion to the vane spindle so that during the time a vane is passing through an abutment the angular movement of a vane is slight. Fig. 1 shows a vane spindle c connected by a crank d' and link d<3> to a bar b which reciprocates in slots a<1> in the rotor body. A link d<2> is pivoted on a pin d<1> of a fixed shaft d, passing through the rotor, and is connected to the bar b. The vanes may be fixed at right angles to each other on opposite ends of the spindle c, or the angle may be other than 90‹. The construction may be varied by connecting the vane spindle to a swivelling attachment on the bar. In another arrangement the pin d<1> supports a bearing at one end in which slides a wrist-pin connected by two arms to the vane spindle c with which the wrist-pin is parallel. The wrist-pin may be pivoted to the arms and the off-set pin d<1> may be so mounted in the stationary shaft d that it is free to move endwise in its bearing, as well as to swivel therein. Fig. 4 shows a further construction in which stationary shafts d<6> are carried in journals aligned with the rotor axis, and a pin d' is supported between the off-set cranks d<8> obliquely across the interior of the rotor in such a plane that the axis of d<7> intersects the axis of the vane spindle c. The vane spindle c is cranked at c<7> and pin d<7> and crank c<7> are coupled by a Y-shaped link d<9>, the head arms d<10> of which turn upon the pin d' while the stem d<11> pivots within the crank c'. When the rotor and vane assembly rotate the Y-shaped link turns upon the stationary pin d<7> and the stem d<11> is rocked and imparts a corresponding rocking motion to the vane spindle crank. In a modified arrangement the rotor spindle has trunnions at right angles to its axis, and supports thereon a cranked arm which is given an oscillatory motion through a pin mounted in a stationary Z-shaped shaft. In Fig. 9 the shaft c is oscillated by means of a swash-plate c<15> pivoted to a ring c<14>, which joins the two shaft ends c. The swash-plate bears on the oblique face of the fixed shaft end d<15>. The annular working chamber may be divided into two by a circumferential web between the vanes, each of which may be in three portions. The two outer sections enter grooves cut into the side walls of the chambers when a vane passes through the double abutment.

Abstract: 792,083. Tractor power take-off mechanisms. FORD MOTOR CO., Ltd. April 29, 1955 [Aug. 24, 1954], No. 24569/54. Class 79(2) A tractor power take-off comprises a primary shaft 1 axially aligned with and directly driven by the engine crankshaft or flywheel (not shown) and a secondary shaft 3 axially aligned with the shaft 1 and driven over an epicyclic gear serving as a simple reduction and reversing gear and as a clutch for engaging or disengaging the drive without the need of stopping the tractor's motion, the gear having a brake band F operating on the planet gear carrier D. As shown the shaft 1 carries a sun gear A meshing with planet gears B mounted on the carrier D carrying a brake drum E, the shaft 3 carrying an annulus C meshing with the gears B. Rotation of the carrier D can be prevented by application of the band brake F to the drum E, thereby transmitting the drive from the shaft 1 to the shaft 3 and when the brake band 5 is released the epicyclic gear disconnects the shafts 1, 3. The shaft 1 passes through a gear cluster of a primary change-speed gear 2 and carries a gear 5 for driving a hydraulic power lift pump (not shown) mounted on the side of the tractor transmission housing. The shaft 3 passes through a gear cluster of a secondary change-speed gear 4. The epicyclic gear may be disposed to the rear of the secondary change-speed gear.

Title: Improvements in the control of lifts operated by polyphase electromotors
IPC: B66B1/08
Filed: 1926-10-05
Abstract: 282,910. Smith, Major, & Stevens, Ltd., and Stevens, P. H. Oct. 5, 1926. Motors, controlling-For controlling a polyphase lift-operating motor by moving the brushes on the commutator, a switch in the cage closes a circuit which controls an auxiliary means or connects to an outside source of power a device whereby the brushes are progressively rocked .against the action of springs or weights to increase the motor speed, the brushes being returned to their original position by the weight or springs when the circuit is opened. Fig. 1 shows the use of a rotary solenoid D<3> in the form of a motor armature having a limited angle of movement for rocking the brush carriers C of a motor B which operates the lift winding drum A<3>. The shaft of the solenoid D<3>, carries drums D<1>, the cords D of which are attached to arms C<2> on the brush carriers and terminate in weights D<4>. A pinion F actuates a dash-pot plunger F<2> and the angular movement of the brush carriers is limited by lugs E which bear on a stop E<1>. When the cage switch G is moved to the left-hand contacts H, H', the solenoid H<2> is energized and the main circuit is closed to cause the lift to ascend slowly. Further movement of the switch to the left-hand contacts H<3>, H<4> energizes the rotary solenoid D<3> and rocks the brushes slowly, against the action of the dash-pot, to accelerate the main motor B. When the switch G is put to the " off " position, the weights D<4> restore the brushes to their original positions at a high speed determined by the dash-pot. Movement of the switch G to the right gives similar operation for lowering. Figs. 2 and 3 show the use of a clutch J to connect an external source of power K to the brush carriers C. The clutch is operated by the core of a solenoid L<1> connected to the points H<3>, H' shown in Fig. 1. Engagement of the clutch tensions one or other of the chains M. M<1> and rocks a lever N, N<2> which is coupled by rods N<3> to the arms C<2> on the brush carriers. The brushes are thus moved against the action of the weights D<4>. In an alternative arrangement, the lever N, N<2> and the rods N<3> are directly coupled to and reciprocated by the core of a solenoid corresponding to the solenoid L', Figs. 2 and 3. Specification 242,714 is referred to.

Abstract: 943,852. Cast concrete floors; metal beams. P. KRAJCINOVIC. July 10, 1961 [July 15, 1960(2)], No. 24912/61. Headings E1K and E1V. A load bearing beam comprises a trough made of steel plate and having longitudinal edge flanges, steel concrete connectors secured to the trough, and means for structurally stiffening the trough against distortion comprising a structure connecting the trough sides while leaving the top of the trough sufficiently open to enable concrete to be introduced into the trough. In Fig. 1 a flanged trough 4, stiffened by welded on battens 6 and plates 10, 11, is provided with U- or loop-shaped connectors 12, 13 welded to the trough walls 5 to bond with concrete cast in the trough above the plate 10. Tubes 15 welded to spacers 16 which in turn are welded to the trough receive pre-stressing cables 14, which are tensioned prior to the introduction of concrete into the trough. Upward convex curvature is thereby given to the trough, which curvature may be increased by an extensible strut applied under pressure between abutments at the top of the trough before the concrete is poured and removed when the concrete has set so that the resilience of the trough applies pre-compression to the concrete therein. In a floor construction the reinforced concrete slab 17, Fig. 2, is cast after the in-situ pouring and setting of the concrete in the troughs 4. The projecting portions of the connectors 12, 13 key the concrete 17 to the troughs. The troughs may be stiffened by a steel lacing or mesh bridging their top flanges. In further modifications, Figs. 7, 8 and 9 (not shown) the trough members are connected by spaced webs to a lower member in the form of a trough or box section.

Abstract: 1367986 Rotary positive displacement pumps P VULLIEZ 30 May 1972 [1 June 1971 8 Sept 1971] 25278/72 Heading F1F A vacuum pump comprises a fixed disc 13' and a mobile disc 23' having co-operating spiral projections 13, 23, the mobile disc 23' performing circular translation movements relative to disc 13' so as to receive gas from a conduit 33 at the periphery of discs 13', 23' and to then compress the gas between the projections 13, 23 before delivering it from the centre of discs 13', 23' to the atmosphere via conduit 35. The fixed body 10, to which disc 13' is rigidly connected, carries three shafts 19 each having an eccentric portion 20 which engages, through bearings 22, the mobile disc 23'. The portions 20 have equal eccentricities E and are synchronized to provide the required circular translation of disc 23'. A central barrel 10', containing conduit 35, connects disc 13' to base 10" of body 10, the barrel 10' being surrounded by a bellows 11 which is sealingly connected via a bell-shaped member 28 to mobile disc 23' and via an annular member 30 to base 10". The bellows 11 thus seals the co-operating discs from the exterior. Cooling fluid is supplied by pump 40 and passes through conduits 41, 42 to a bulb 43 and the centre of spiral 13 and thence through conduit 44 to a bulb 45 in the centre of spiral 23. In operation, for a particular cycle, gas is drawn into the periphery of discs 13', 23' from conduit 33 which leads to the chamber to be evacuated. This process of suction occurs during a first revolution of disc 23' and at the end of it gas is trapped in volumes V 1 , Fig.2. A further revolution of disc 23' leads to compression of gas to the volumes V 2  and a still further revolution produces more compression, the two chambers being merged to a simple chamber V 3 . A final revolution of disc 23' causes the gas to be discharged through valve 34 and conduit 35 to the atmosphere. Alternatively Figs.4 and 5 (not shown) there can be two sets of co-operating spirals, the first having no bulbs and taking gas at the centre and discharges it peripherally to the second set which act as set out above. In a miniaturized version Figs. 6 and 7 (not shown) the vacuum pump is assisted by a diaphragm pump.
