Title: Improvements relating to scaffolds with moving platforms, elevators and the like
IPC: E04G1/20
Filed: 1946-09-16
Abstract: 632,579. Scaffolds with moving platforms. SANTI, T. G. DI. Sept. 16, 1946, No. 27669. [Class 20(ii)] [Also in Group XXX] A scaffold for workmen comprises vertical parts with parts slidable thereon which form part of a brake unit supporting a working platform the weight of which is used to operate the brake or brakes of the unit to hold the platform in any position on the posts. Manually operated brake release means are provided. As described each brake unit 18 comprises two sleeves 19, 20 sliding on a pair of parallel posts 16, 17 and rigidly joined by a framework 21, 22, 23, 26. The sleeves 19, 20 are slotted to clear lugs 70 on the posts to which cross bracing 68 is secured, the bracing connecting the posts 16, 17 to a similar pair on which slides a second brake unit, the two units supporting the platform between them. A T-bar 30 on which rests one end of the platform has depending legs 32, 33 fitting into slots 25, 28 in the framework and pierced by two holes through which pass levers 37, 38 pivoted at 37a, 38a to the framework. The lower ends of the levers enter sockets 39, 40 in brake shoes 41, 42 slotted to slide on inclined ledges 46 on the members 22 of the framework. The weight of the platform thus forces the brake shoes against the posts 16, 17. The brakes may be released by lifting and pushing down a handle 56 which turns, through lever and ratchet mechanism, a plate 66 which raises the levers 37, 38. A further up and down movement of the handle allows the brakes to re-engage. For raising and lowering the platform, the brake unit 18 is suspended by block and tackle from a similar unit 75 initially positioned at a suitable height on the posts and comprising a pair of sleeves 76 joined by a framework 77 to which are pivoted levers 82, 83 operating brake shoes 79 and passing through a hole in a vertically slidable plate 88 to which the upper block 98 is secured. A lever 94 is provided operating a bolt 92 to lock the plate 88 in the brakes released position. In a modification (Fig. 12) the platform rests directly on framework 210 joining sleeves 212, 213 sliding on posts 214, 215, the operating levers 220, 221 for the brake shoes 216, 217 are pivoted at one end to the shoes and at the other to the framework 210 at 222 and springs 224, 225 assist to urge the shoes against the posts through pivoted levers 232, 226 and 233, 227. The brakes may be released by depressing a lever 249, 237, pivoted at 236, which carries a roller 238 engaging the levers .232, 233. The brakes may be locked in the released position by pulling a cord 271 which rotates, through ratchet mechanism, a plate 252 into contact with an extension 239a, of the lever 237. Further rotation of the plate 252 unlocks the brakes. This modified brake unit is suspended from a modified upper unit which is clamped to the posts at a suitable elevated position by screwoperated jaws.

Title: Improvements in and relating to the starting of automobiles
IPC: F02N1/00
Filed: 1926-11-04
Abstract: 277,826. Snell, S. Nov. 4, 1926. Turning-gear.-In order to enable the manual effort applied to the starting handle or the like of a motor-vehicle engine, to be augmented automatically by an electric or other starting motor, a connection is provided between the starting- handle and the controlling means of the motor. In one form, Figs. 1 and 2, a double arm b on the shaft a of the starting handle actuates intermittently a tongue c on a slide d which actuates an electric switch e for the starting motor. The switch e is in parallel with the normal starting- switch, or is adapted to be operated independently of the starting-handle by a Bowden-wire connection g to a plunger h on the dashboard. In a modification, Fig. 5, a starting switch q on the dashboard is connected by a Bowden wire g to a slide similar to d actuated by the starting handle, the wire g being connected to an arm or a pair of leaf springs s on the plunger h of the switch. If the engine backfires at starting reverse rotation of the starting handle is prevented by the opposing torque of the starting-motor.
Patent GB-829719-A (GB)
Title: Sheet feeding apparatus
Inventor: MENTZER JAMES SAMUEL
IPC: B65H3/52
Filed: 1957-09-03
Abstract: 829,719. Feeding sheets. CUMMINSCHICAGO CORPORATION. Sept. 3, 1957, No. 27725/57. Class 100(1) In a sheet-feeding apparatus comprising a sheet-separator which supplies sheets from a stack or other source to a pair of feed rollers, the feed rollers have friction surfaces in rolling engagement with one another and one roller is power driven, and the arrangement is such that when two or more sheets are supplied to the feed rollers, the friction driven roller ceases to rotate, and such non-rotation causes the sheet-separator to be disabled. As shown, sheets 22, such as cheques, in a stack are separated sequentially by a friction roller 25 which protrudes through an aperture 24 in a plate 23 and co-operates with a plate 30 which is curved upwardly towards the roller to reduce the likelihood of feeding more than one sheet at once. The roller 25 is of rubber and is formed with spaced ribs 27 on its periphery. It is coupled to a shaft 26 by a coil spring 29 which constitutes an over-running clutch 28. The feed rollers comprise a powerdriven roller 40 and a friction-driven roller 45, both having rubber peripheries. The roller 45 is secured to a shaft 46 and is braked by means of a friction disc 55 which is retained against rotation by an anchor 60, and is urged against the side of the roller by a spring 62. The shaft 46 is mounted in arms 48, 49 swingable about a shaft 50 and biased upwardly by coil springs 51, 52 to urge the roller 45 against the roller 40. The shafts 26 and 46 are connected by gears 71, 72, so that the separator roller 25 will cease to rotate when the roller 45 is stopped due to the presence of two superposed sheets between the rollers 40, 45, since in that case the roller 45 is not driven. Relative slippage takes place between the two superposed sheets, enabling the top one to be discharged by the roller 40, and the lower sheet is held back on the surface of the braked roller 45: when the top sheet is clear, the lower sheet is then discharged by the two rollers. The over-running clutch 28 ensures that one further sheet is separated from the pile by the roller 25 even when the roller 45 is stopped. The sheets are passed between transport rollers 73, 74 driven at a higher peripheral speed than the roller 40. In a modification, the separator roller is driven through an electric clutch by a motor which also drives the top feed roller, the clutch being controlled by the lower friction-driven feed roller such that the separator roller is not driven if the lower feed roller does not rotate due to the presence of two superposed sheets. In this case, there are two or more sets of feed rollers which can cope with circumstances in which three or more sheets are separated together from the pile. A rotation detector is mounted at the end of each braked roller for the purpose of operating electric contacts in the circuit of the electric clutch in response to the rotation of the braked roller. The clutch is rendered inoperative when more than one sheet is present between any of the sets of feed rollers.

Abstract: 333,771. Barmer Maschinenfabrik Akt.-Ges., and Lenk, M. Sept. 12, 1929. Ring twisting-frames; spindle and lifting rails; building-motions; thread guides; spindle-driving apparatus; creel arrangements.-In ring twisting- machines, particularly intended for twisting artificial silk, the ring rails are connected to a common frame 23 slidable on guide-bars 24 and coupled by chains 27 to a bar 5 operated by the building-motion and the delivery bobbins 6 are driven by helical gears 14 arranged in a casing 16. The thread guides 21 are carried by the frame 23 so that they remain at a constant distance from the rings. The guide-bars 24 are spaced from the plane in which the spindles are mounted so that broken ends will not be soiled by contact therewith. The spindle-driving shaft is driven by gearing 9 from a shaft 8 which also drives the delivery bobbins through gears 10 and sprocket gear 12. The building-motion comprises an eccentric 18 which oscillates a slide 17 connected by chains 19, 19<1> with the bar 5, the lift being effected by rotating a sheave 32 on the slide, to which the chain is connected, by means of worm gear 31 operated by ratchet-mechanism. The gearing is enclosed in a casing 2 at one end of the machine.

Abstract: 988,860. Insulating railway rails. ETERNIT S.p.A. Aug. 3, 1961 [Aug. 4, 1960], No. 28204/61. Heading E1G. An electrical insulation device for the insulation of the rails, as 1, of railway lines with respect to the sleepers, as 3, is characterized in that a bushing 4 is enclosed in the sleeper itself, when the sleeper is manufactured, a layer of insulating material 5 being interposed between the bushing and the sleeper and provided with grooves which prevent sliding or rotation of the bushing when the bolt is tightened. The rail 1 rests on a layer of insulating rubber 2 on the sleeper 3, which is of asbestos cement. The bushing 4 may be frustoconical in shape, and has parallel grooves round its outer surface in planes at right angles to the central axis of the bushing to prevent it from sliding out of its seating. The layer 5 of insulating material is provided on both sides with peripheral grooves to co-operate with those on the bushing 4 and also to grip the sides of the seating for the bushing. Vertical grooves are provided in the bushing and vertical ribs on the outside of the layer of insulating material 5 to prevent rotation of the bushing and the layer of insulating material 5 respectively. Alternatively the grooves in the bushing and the layer 5 may be helical. A bolt 6 with n T-shaped head is inserted into the bushing and is anchored by rotation of the bolt in the same direction as that of tightening a nut 7 which clamps a spring plate 8 serving to fasten the rail to the sleeper in place. A layer of insulating material 9 comprises a sheet of insulating material interposed between the two arms of a folded U-shaped sheet of non- hardenable bituminous material. When the nut 7 is tightened part of the bituminous material is squeezed out round the plate 8, as at 10, to provide a watertight insulation.

Title: Tetramethyl titanate
Inventor: STANLEY ROBERT HOLROYD
IPC: C07F7/00
Filed: 1961-08-03
Abstract: Tetramethyl titanate is prepared by adding a dry tetraalkyl titanate, in which each alkyl group contains 2-4 carbon atoms, to dry methanol and recovering the substantially pure solid tetramethyl titanate precipitated.  The reaction is preferably carried out at a temperature substantially below the boiling-points of the alkanol produced and of methanol and in particular at room temperature or below.  The tetramethyl titanate may be separated from the reaction mixture, for example, by filtering or centrifruging and may be subsequently dried by heating. The tetraalkyl titanates used as starting materials may be obtained by reacting dry titanium tetrachloride and excess dry alcohol and thereafter introducing ammonia until no more ammonium chloride is precipitated.  The use of tetraisobutyl titanate as starting material is excluded from the scope of the invention.

Filed: 1959-08-20
Abstract: 902,730. Endless conveyers. BARRACLOUGH Ltd., R. W., and BARACLOUGH, R. W. Aug. 23, 1960 [Aug. 20, 1959], No. 28440/59. Class 78 (1).  In apparatus for feeding articles 12 to a case-packing-machine the articles are transported in a plurality of guideways 17, 18, 19 by individual conveyer belts 17a, each guideway guiding the articles in a single file and delivering them to an aligned intermediate support 20, and individual transfer means for each intermediate support, each adapted to operate only when the associated intermediate support has received a predetermined number (four, as shown) of articles to transfer the articles thereon to a receiving conveyer. The receiving conveyer comprises intermittently driven endless chains 13, 14 arranged transversely to the guideways and carrying cross-bars 15 on each of which are mounted pushers 15a-16d corresponding in number to said predetermined number. The pushers project through slots formed by slides 11a-11e and are pivotable, being maintained erect on their conveying run by a ramp 16. Each support 20 consists of a pair of plates 20b, 20c having inturned upper edges 20d, 20e. Each support is mounted for movement parallel to itself by parallel links 23, 24 and is independently movable by a lever 25 having a roller 25a coacting with a corresponding one of three cams 26 driven in timed relationship with the receiving conveyer. Each roller 25a is normally prevented from following the contour of the associated cam by a solenoid-operated latch 27 which is withdrawn only when the corresponding one of three micro-switches 28 is operated by the foremost article on the associated support 20, i.e. when the support carries a full complement of articles. The arrangement is such that if a switch 28 is not operated until after the roller 25a has left the high part of the cam 26 the solenoid 27 is not operated and a batch is delivered from only two of the guideways, the articles from the third guideway awaiting the next cycle of cam 26. Delivery of the batch from the supports to the transverse conveyer is effected automatically when the supports have reached their lower position by endless chains 30 each passing between the plates 20b, 20c of the associated support 20, the chains carrying pushers 31 and being adapted to be driven for a distance sufficient for a pusher 31 to transfer the articles from the support 20 on to the receiving conveyer. For this purpose, each chain 30 is driven by a motor which is controlled by a switch 36 operated by a cam 35 on the shaft 33 which carries cam 26. A stop 29 attached to each support by a bracket 20h arrests the articles on each of the belts 17a  when the associated support is in the loweredposition. Specification 739,373 is referred to.
