Title: Improvements in or relating to load handling appliances having tiltable masts with trolleys thereon
Inventor: EDEN JOSEPH FOLKARD
IPC: B66F9/19
Filed: 1963-01-24
Abstract: 1,086,944. Masted lift trucks. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 24, 1964 [Jan. 24, 1963], No. 2974/63. Heading B8H. [Also in Division E1] In a lift truck provided with a lifting carriage movable on a tiltable mast and a load carrier mounted on the lifting carriage, the load carrier or a part thereof is arranged to be movable outwardly of the lifting carriage. As shown in Fig. 1 (c), a skip 98 is pivotally supported by pins 92 on the lifting carriage 91 and is connected by links 96 to fixed points 97 on the mast 94. With the lifting carriage at the lower end of the mast, forward and rearward tilting of the mast moves the skip into the shovelling and transport positions, Figs. 1(a), 1(b) (not shown). On raising the lifting carriage, the skip is tilted into a discharge position by the links 96. The mast may be used as a crane jib by detaching the load support from the lifting carriage, detaching the lifting carriage from the hoist rope and by tilting the mast forwardly. In a modification, Fig. 2 (not shown), the hoisting cable passes from the pulley at the top of the mast, under a pulley on the lifting carriage to an anchorage at the top of a skip pivotally mounted on the lifting carriage, whereby the skip is prevented from tipping to the discharge position when the hoisting cable is under tension. To discharge the skip, the lifting carriage is raised until it is supported by pivoted catches on the mast after which paying out of the hoist cable allows the skip to tip. When the mast is so mounted on the truck that the front wheels of the truck extend in front of the lifting carriage, a bolster 115, Fig. 3, is connected to the lifting carriage by toggle links 118 so that it may be projected to the broken line positions to prevent wide loads from engaging the wheels. In a modification, Fig. 4 (not shown), a lift fork is connected by parallel links to the lifting carriage and the hoisting cable is connected directly to the fork so that when the lifting carriage engages stops at the bottom of the mast, further paying out of the hoist cable allows the fork to swing forwardly and downwardly to its fully lowered position. In a further embodiment, Fig. 5 (not shown), the mast is bent rearwardly at its upper end and a shovel is pivoted to the top of the lifting carriage. To discharge the shovel rearwardly at the top of the mast, an hydraulic ram adjacent the top of the mast is extended to engage and raise a projection on the rear of the shovel to tip it rearwardly.

Title: Improvements relating to the setting of spools
IPC: D03D39/06
Filed: 1959-01-28
Abstract: Spools are set by winding on to a storage member a succession of single yarns sufficient to fill a plurality of spools and then transferring the stored yarns collectively on to the spools in the requisite lengths.  Two embodiments are described.  Firstly; differently coloured yarns are joined end to end, corresponding to the colour in a warp-wise row, are wound on to the member and the procedure is repeated for the next warp row until the member contains yarn sufficient for at least one pattern or unit of a pattern, whereupon the yarns are transferred collectively to the spools which then each contain the yarns weft-wise in the right sequence of colour.  In this embodiment the winding machine needs only one bobbin for each colour of yarn.  Secondly; different coloured yarns are wound weft-wise into the member and then transferred to the spools. In this embodiment each weft position has to be provided with the selection of colours appearing in a warp row.  A winding machine has a jacquard to select the yarns and to present them to a marking station where, at spool lengths, a bead is moulded on to the yarn. The bead may be utilized to join yarns of different colours.  The yarn is then wound on a storage member which may consist of separate sections for each warp row.  A feeler feels the yarn and controls a variable speed yarn drive.  Upon collective transfer to the spools the yarns are severed at the correct lengths indicated by the moulded beads.

Title: Improvements in and relating to upper cylinder lubrication of internal combustion engines
IPC: F01M3/04
Filed: 1929-01-30
Abstract: 330,227. Innes, G. P. Jan. 30, 1929. Lubricant conveyed by fluid.-In a lubricating device for internal-combustion engines wherein air is drawn by the engine suction from the atmosphere through lubricant in a vessel 14 into the intake manifold 30, the connection to the manifold is disposed either at a point 32 between the carburettor and the throttle 33 or at a point 34 beyond the throttle, in which latter case the connection includes a check valve, which closes automatically as the suction increases. The supply of lubricant carried by the air into the manifold is thus caused to be proportional to the supply of fuel. The glass vessel 14 is clamped between a cap 9 formed on a bracket 5 and the end 13 of a lever 10 adjustably mounted on the bracket. A passage 21 in the cap communicates with a tube 24 depending into the lubricant and with a pipe 23 open to the atmosphere. An outlet passage 18 in the cap, controlled by a valve 16, communicates with the pipe 19 leading to the manifold 30. The check valve 40, mounted in a two-part casing 35, 36, is acted upon on opposite sides by springs 39, 41 so that the valve is normally maintained open but closes progressively as the suction in the manifold increases. The loading of the valve may be raised by screwing the casing part 35 on the part 36. The vessel may be refilled by inserting the pipe 23 into a lubricant container, with the engine running.

Title: Improvements in or relating to shoe upper conforming machines
IPC: A43D21/12
Filed: 1942-03-14
Abstract: 556,240. Lasting machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). March 14, 1942, No. 3381. [Class 17 (i)] A machine of the kind described in Specification 520,194 is provided with a retarder instead of grippers. The retarder comprises a V-shaped wire member 26 with inturned ends engaging a V-shaped member 28 near its base, the ends of the arms of the member 28 being pivoted to a V-shaped bracket 30 fixed to the hold-down 6 and provided with out-turned lips 32 overlying the ends of the arms of the retarder. The part 4 of the hold-down carrying the retarder is removable so that a retarder and insole-lip support for the particular last in use may be readily positioned, pull on a knob 16 retracting a slide carrying fingers 14 engaging recesses in the part 4. The retarder is controlled by a lever 34 restrained by a pivoted link 42 and actuated by an arm 36 integral with an arm 48 angularly adjustable toward and away from an arm 52 integral with the upper part 54 of a clamp embracing a friction ring 58 held in fixed relation to a cam-operated rock shaft 38 by a pin 60. The part 54 is connected by a link 64 with the lower part 56 of the clamp, which is tightened on the friction ring by a link 68 and lever 66 urged anti-clockwise by an adjustable spring 70. A slot 94 allows the clamp imited movement around the ring. In operation, the rock shaft 38 is swung to depress the lever 34 to cause the retarder to grip the upper as the wipers 2 swing upwardly for the up-wipe. As the wipers continue to swing upwardly the grip is increased as the lever yields against the friction of the clamp and the pull of the spring 70. As the retarder is raised at its toe-ward end it is forced rearwardly and its heelward end is lowered so that an increasing portion of the upper margin at the sides of the toe is effectively retarded. Just before the wipers have completed their up-wiping movement, the rock-shaft 38 begins to turn reversely, to reduce the pressure on the retarder to minimize the danger of the wipers displacing the edge of the insole as they commence their overwiping movement. Before the completion of the over-wipe the margin is substantially free from pressure.

Filed: 1953-02-06
Abstract: 724,932. Load-handling machines. SAFWAY STEEL PRODUCTS, Inc. Feb. 6, 1953, No. 3426/53. Class 78 (3). [Also in Group X] A telescopic tower for supporting a work platform 38, Fig. 1, comprises telescopic tubes 10, 34, 36, containing a hydraulic ram and cylinder and a system of cables and pulleys, so arranged that an extension of the ram and cylinder through a given distance extends the tower through six times that distance. The hydraulic cylinder 54, Fig. 5, is secured in the tube 36 and the hydraulic ram 64 is rigidly connected to a pulley block 72 slidable in the tube 34. A pulley 58 is mounted at the upper end of the cylinder 54. One end of a cable 70.is attached to the ram 64 and passes around pulleys 58, 72 and is connected at its other end to the top of the tube 34. A given extension of the ram and cylinder acts through cable 70 and causes the tube 36 to rise three times that distance within the tube 34. A pulley 94 is mounted at the bottom of the tube 34 and one end of a cable 92 is attached to the lower end of the tube 36, passes around the pulley 94 and is connected at its other end to the top of the tube 10. When the tube 36 rises a given distance within the tube 34, the cable 92 acts upon the pulley 94 and lifts the tube 34 through the same distance with respect to the tube 10. The total extension of the tower is the sum of the extensions of the tubes 34 and 36. A pump having a hand lever 44, Fig. 1, is provided for pumping oil into the hydraulic cylinder. Alternatively, a motor driven pump may be employed. A telescopic air ram formed by' tubes 100, 102, 104 is mounted alongside the lifting column and serves to prevent the platform 38 from rotating and retards the gravitational descent of the platform in the event of failure of the lifting mechanism. The platform 38 has a guard rail 48 which may be lowered on to the platform and the tower is mounted upon a wheeled base formed by legs 12 which are swingable to a position in which the tower may be moved through narrow spaces. The tower may be mounted on a truck or other vehicle in which case a power take-off may be employed to operate the hydraulic ram instead of a manual pump. Specification 532,050, [Group XIV], is referred to.
