Title: Improvements in or relating to change speed gears
IPC: F16H33/16
Filed: 1921-12-30
Abstract: 176,325. Guiraud, H. J. March 3, 1921, [Convention date]. Variable-speed epicyclic gearing is controlled automatically by a braking action upon the planetary elements exercised by fluid friction. Arms d, Fig. 1, fast upon a driving-shaft a carry planet gears c<3> meshing with a gear b<1>, secured to the driven shaft b. The free rotation of the gears c<3> is restrained so that the shaft b is driven at varying speeds by fluid friction drums c, Fig. 2, which turn in the same direction as the arms d. These drums have vanes c<2> running their whole length inside, inclined against the direction of rotation as shown. Oil or glycerine in the drums is subjected to centrifugal force produced by rotation about two different axes, and the forces produced by viscosity resist the turning in a varying ratio. The application to motor-vehicles is mentioned.

Title: Improvements in liquid dispensing machines
Inventor: ROUNSIVELL WILFRED ARTHUR
IPC: G07F13/06
Filed: 1962-09-18
Abstract: 975,338. Dispensing liquids. SOUTHERN INDUSTRIES (CROYDON) Ltd. Sept. 11, 1963 [Sept. 18, 1962], No. 35397/62. Heading A4T. [Also in Division G4] A liquid dispensing machine of the type having storage containers 12, Fig. 3, for e.g. solutions of sugar, milk, tea, coffee, automatically replenishing open reservoirs 10, Fig. 11, thereunder from which means deliver predetermined quantities to a delivery channel 18, has a setting mechanism comprising a shaft 8 carrying cams 12a-15a, for selecting a combination of liquids, each of which at its high point lifts a link 30 about pivot 54 so that a pin 32 on a scoop funnel 21 enters the large horizontal part of L-slot 31 and the link can move without moving the pin, and at its low point allows the pin to move into the vertical part of the L-slot whereby the link can move the pin. On manual setting of the cams via gears 11, an interlock 49 and e.g. a coin-actuated device 59 permits manual shifting at 44 of bar 39 against return spring 41 under the control of a dashpot or timer 43 whereby lever 20 deposits a cup beneath channel 18, cranks 52 are turned to move links 30 so that the selectively lowered links tip their scoops about pivots 22 to lift a quantity of solution from the reservoirs and empty it into the channel via funnels 23, 24 on the return movement. Finally a crank directly lowers a scoop 63 into a hot water reservoir 65, outside refrigerator 35 holding the containers, for flushing the other solutions from the channel into the cup. The scoops may be replaced by valve apparatus and the containers, reservoirs, scoops and funnels are releasably clamped so that they can be removed for cleaning or scoops of different sizes introduced.

Abstract: 1,249,429. Retractable ball-point pens. K.C. PEN CO. Inc. 22 July, 1970, [31 July, 1969; 20 April, 1970], No. 35521/70. Heading B6P. A retractable ball-point pen comprises a barrel 11 including an internally threaded upper section 16 and an upper cap-section 12 rotatably supporting an externally threaded coaxial tubular actuator 23, which releasably engages the barrel threaded section 1.6. A cartridge carrier 33 slideably and. rotatably registers with the actuator upper portion. An inner. arcuate flange 19 (Fig. 4) affixed to the cap section is spaced from the carrier 33 to delineate an arcuate passageway (36) terminated by two stop shoulders (21) 200 degrees apart. An axially extending finger (24) affixed to the actuator 23 is movable along the arcuate passageway (36) between the shoulders (:21). A finger 22 projects from the flange 19 into engagement with an axial groove 34.in the carrier 33. The carrier 33 and the actuator 23 have complementary cylindrical cams 32, 40. Relative rotation between the barrel 11 and cap 12 causes the same relative rotation between the actuator 23 and the carrier 33, so that cams 32 and 40 cause projections and retraction of the cartridge. In an alternative embodiment (Fig. 9), interaction of the projecting and retracting cams restricts the relative rotation of the cap and barrel.

Title: Improved automatic device for the manufacture of parcel carriers
IPC: B31D1/06
Filed: 1954-12-10
Abstract: 795,241. Feeding webs. VOGL, H. W., EHRMAN, K., WEINER, G., and VOGL, O., [trading as CARRY-PACK CO., Ltd.]. Dec. 10, 1954, No. 35865/54. Class 100(1) [Also in Group XVII] Parcel carriers consisting of a gummed tape 61 having secured to it a ribbon 109, a free loop of which is passed through a slot 230 in the tape, are made in a continuous web on a machine of the kind comprising a reciprocating head carrying slotting tools and having operating independently within it a plunger for passing the ribbon loop through the slot, the machine having improved means for controlling the feed of the ribbon, tape and web. The tape 61 passes from a roll 250 round a pulley 63 for taking up slack due to intermittent feed over pulleys 68, 69 and past an intermittently raised clamping device 79 to beneath the reciprocating head 26. The head carries cutters 35-37, forming the slit 230 and apertures 229 respectively, and presses 38, 39 which press reinforcing strips on to the tape. These strips 149 are fed in at right angles to the path of the tape by ratchet means (Figs. 4 and 5, not shown), past gluing nipples and cutters to lie on the tape. The ribbon 109 is drawn from a roll 110 by feed wheels 256, 257, the latter being driven at variable angular velocity by an eccentric pulley 92, belt 94 and pulley 93. The pulley 93 comprises axially fixed and slidable parts 93B, 93A, respectively (Fig. 10) the latter being movable by a handwheel 126 and lever 130 to adjust the effective radius of the pulley 93 and thus the feed velocity of the ribbon. The ribbon passes over take-up means 115, 116 through the head 26 to lie beneath a spring-loaded presser 121. The tape 61 arrives beneath prongs 43 of a plunger 42 which force the ribbon through the slot 230 prior to descent of the head 26. Pressers 53, 57 cause the ribbon to adhere to the tape and a cutter 55 cuts slots 228, facilitating subsequent separation of individual carriers. The completed web is intermittently gripped between the raised portion of a cam 174 and a wheel 177 for drawing it through the machine, and it passes round a take-up pulley 212 and pulleys 202-204, 206, 207, 209, 210 to a driven collecting roll 197. The web is clamped by an element 192 when stationary and the speed of the collecting roll is controlled by a brake operated by members 221-224 connected to the pulley 212. The pulley 212 is carried by an arm 213 and should the web break, this arm drops, operating a switch to stop the machine. Reference has been directed by the Comptroller to Specification 727,341 [Group XVII].

Abstract: 1,205,821. Change-speed gears. UNITED GAS INDUSTRIES Ltd. 9 July, 1969 [26 July, 1968], No. 35897/68. Heading F2D. A two-speed toothed gear drive with no neutral position, for a variable tariff, e.g. pricing mechanism of an electricity or gas meter, comprises an integral pair of toothed wheels 5, 6 rotatably fast with but axially slidable on a hexagonal output shaft 2 into mesh with one or other of two gears 3, 4 integrally formed on an input shaft 1, the overall width of the slidable output gear pair 5, 6 being greater than the spacing between the input pinions 3, 4 whereby during ratio shift, i.e. axial sliding of the gear pair 5, 6 the gearing is locked, the new ratio being established before disengaging the existing ratio to avoid a neutral condition in which power (i.e. gas or electricity) could be consumed without the associated credit being recorded on the meter. Change of ratio is effected by manually turning in one or other direction, via a screw-driven slot 25, a helically splined shaft 18 to axially move a striker arm 12 correspondingly splined thereon and prevented from rotation by an axially extending fixed pin 19 piloted in the arm 12 at 20, the arm 12 having a forked end 15 carrying axial pins 13, 14 engaging with slight clearance each side of a disc 7 fast with the integral gear pair 5, 6 for axial gearchanging movement thereof, the pins 13, 14 being formed of or coated with a low friction material. The screw-driven slot 25 is formed at the end of shaft 18 in the face of a separate pinion 21 which meshes a quadrant marked with the relevant meter rates A or B one or other of which appears in an indication window 24 only when the appropriate gear pair 3, 5 or 4, 6 are fully meshed and the other pair completely disengaged, which condition allows a spring- loaded plunger (not shown) to engage one of two holes in a disc (not shown) ensuring correct complete movement of the sliding gear pair 5, 6 before the meter cover (not shown) can be replaced after such a gear ratio change, i.e. meter tariff change from A to B or vice-versa. The shafts, gears and various other components of the mechanism may be moulded in or constructed from synthetic plastics material.

Abstract: 800,079. Assembling force fits. SCHLOEMANN AKT.-GES. Nov. 28, 1956 [Dec. 2, 1955], No. 36360/56. Class 83 (4). [Also in Group XXIII] In a method of removing a shrunk tapered sleeve 18 from a tapered bush 17 on a rolling mill roll 2 using fluid pressure means between the surfaces 27 a force is applied to hold the sleeve 18 in position until the.fluid pressure has built up sufficiently for the parts to be in the floating state, when the force is suddenly removed and another force is applied in the opposite direction to separate the parts. The roll 2 is supported by its bearing housings 1 on a pair of carriages 14, 15 and is located longitudinally between end pedestals 3, 4 which are braced by tie rods 6, 7. One end of the roll is located against an intermediate piece 12 adjustable by a screw 13 in the pedestal 4 and the other end is located against a piston rod 9 bolted by an extension 8 to the pedestal 3. A double-ended cylinder 20 sliding over the piston 21 is bolted at 19 to the sleeve 18 to be removed, the weight of the sleeve being supported by inclined rollers 24 on a bracket 25 adjustable on the carriage 15. For applying or removing the sleeve 18, hydraulic pressure is applied between the forcefitted surfaces 27 through a bore 26 from an hydraulic multiplier. When applying the sleeve 18, pressure is supplied to the space 22 in the cylinder 20. In removing the sleeve 18, pressure is initially supplied to the space 22 to impose a force tending to hold the sleeve 18 in position until it is fully floating. The pressure in the space 22 is then suddenly released by a valve 42 which directs some of the escaping fluid into the chamber 23 so that cylinder 20 is urged to withdraw the sleeve. Complete withdrawal is obtained by supplying pressure fluid to the space 23. Valves (not shown) controlling the pressure supply are operated from cams on a pair of shafts which are common to some of the valves and arranged so that all the operations can be controlled by a pair of levers.
