Title: Improvements in or relating to portable cranes
IPC: B66C23/36
Filed: 1940-09-14
Abstract: 542,786. Cranes. ORTHOSTYLE, Ltd., and CODD, R. Sept. 14, 1940, No. 14200. [Class 78 (iv)] The jib is pivoted on a portable crane at a point intermediate its length and is raised to, or lowered from, its operative position by the hoisting rope which passes round a pulley at the lower end of the jib, the hook being then anchored to the jib. The jib 10, 22 is pivoted at a point 18 to braced standards 17 on a carriage 11. When in the raised position shown in full lines, a stay 32 becomes taut and the lower end of the jib bears against an abutment plate on the carriage and is locked thereto by a cotter pin. The hoisting rope or chain 19 is led from the upper of two pulleys 20, 21 over a pulley 23 at the angle of the jib, and thence over a pulley 24 on the lower extension of the jib to a winch 25. When the hook 33 is anchored to a p int on the jib, and the cotter pin adjacent the abutment plate is removed, the jib may be lowered gradually by the winch into the position shown in dotted lines. The rope then engages pulley 31 on the carriage 11 to ensure effective leverage on the jib.

Filed: 1944-07-26
Abstract: 591,811. Well masts. MOORE & CO., Inc., L. C. July 26, 1944, No. 14272. Convention date, April 10. [Class 78(iv)] In an oil well mast &c. having a crown pulley block 10 at the top and a winding drum 8 at the bottom located so that the cable 16 from drum to crown runs outside the rear 6 of the mast 1 a fair-lead 18 is so disposed near the top as to guide the cable on to the take-up end pulley of the travelling block 17. The fair-lead 18 is mounted in a journal frame so that it stands askew of the rear face 6 of the mast and has its outer rim close to the vertical plane passing through the middle of the drum 8 and of the mast 1. The inner rim lies over one end pulley of the block 17 so that the cable will run on and off same with minimum side scrape, and the medial location of-the outer rim permits the cable to wind on the drum 8 more evenly than if the outer rim were at one side. The journal frame carrying the lead 18 is bolted to the mast 1 in a manner permitting reversal of the frame so that the inner rim of the lead 18 may lie over either end pulley of the block 17 at will. The cable 16 after passing over the pulleys of blocks 10 and 17 is taken over a pulley 13 disposed at right angles to the pulleys of the blocks 10 and 17 and thence down inside the mast 1 for attachment near the lower front corner.

Title: Improvements in Welding Controllers.
IPC: B23K9/067
Filed: 1918-09-03
Abstract: 129,858. Igranic Electric Co., (Cutler-Hammer Manufacturing Co.). Sept. 3, 1918. Regulation, automatic systems and apparatus for.-In electric-arc welding circuits, an electric switch, automatically closed by a reduction of current, is employed to shunt a starting resistance as the electrodes are separated after striking the arc. In the arrangement shown in Fig. 1, during starting the mains 7, 8 are connected through the work 3, the electrode 4, the holding and closing coils 11, 10 of a switch 5, of which the coil 11 is of less reluctance than the coil 10, and also through the starting-resistance 2, the switch-arm 9 being held in the position shown. As the electrodes 3, 4 are separated, the current strength falls and the coil 10 attracts the arm 9 so that contacts 12, 13 are closed and an increased current passes through the arm 9 and shunt 15. In this form, the coils 10, 11 are always in circuit. Fig. 4 shows an arrangement in which only the coil 10 remains in circuit during working, the arm 9 being connected to a point 17 between the coils 10, 11. In this form a working resistance 23 is always in circuit and the starting resistance 24 is adjustable. In modifications, there may be no working resistance, or the working, resistance may be variable and be cut out during starting. In another modification, the switch coils may be cut out of the shunt circuit, but may receive enough current through the resistance circuit to keep the switch in operation. In another form, the current through the coils may be provided for by arranging a special shunt always exciting both coils, or, as shown in Fig. 6, such a shunt 19 may be reinforced by a further shunt connexion 18 passing current through the coil 11 during the working operation. In another modification, the closing switch coil is arranged in a shunt circuit through which the current always flows, only the opening or holding coil being arranged in the main shunt circuit. In the form shown in Fig. 9, the coils 9, 10 are arranged in the starting-circuit, which includes the starting resistance 5, but a second reinforcing closing coil 11, consisting of a few turns of thick wire, is arranged in the main shunt circuit, which includes the working resistances 6, 8, in order to keep the switch closed. Fig. 10 shows the switch, in which the coil 11 surrounds the coil 9 and is connected to it bv a terminal 16. The switch-arm 12 falls to the open position under the action of gravity.

[Class 39(iii)] In an electric fire adapted to be supported from a wall or ceiling, the inclination of the fire is adjustable by means of a control rod 17 which carries switch operating means for switching the current to the fire on and off. The switch 25 is preferably of the " ceiling type and is connected by a cord 26 passing over a pulley wheel 29 and through the hollow control rod 17 to a tubular handle piece 27 which is movable longitudinally of the rod to actuate the switch. A reflector 1 carrying a heating element (not shown) is pivoted about a rod 7 by lugs 8, 9 and connected to an insulating ferrule 22 on the rod 17 by a link 20 attached to a lug 21 on the rear of the reflector. The control rod 17 is secured at its upper end to a rod 18 pivoted in end brackets 5, 6 attached to the wall or ceiling, and this allows movement of rod 17 in the plane of the paper. The fire is held at any desired inclination by suitable friction or other securing means between lugs 8, 9 on the reflector and the respective brackets. The control rod may be made in sections secured together by threaded joints to facilitate packing, and the lowermost section may be covered with an insulating material 19.

[Class 87 (ii)] [Also in Group XVII] Hollow articles, such as milk bottles, are cast centrifugally by projecting a filament of a solidifiable solution of cellulose acetate on to the interior surface of a rotating mould moving also in an axial direction so as to deposit the filament in a uniform helix, the convolutions of which merge together to form a coating of uniform thickness. The solution is supplied by a pump 5 through a tube 7 terminating in a nozzle 8 having one or more lateral orifices. The mould 10 is in two parts and is supported on a spigot 13 driven by an electric motor 14. When moulding a shaped article such as a bottle the mould is reciprocated vertically at a non-uniform speed in accordance with the variations of peripheral speed by means of a heart-shaped cam 15 and five-sided roller 16 through gearing 22, a counter-weight 30 being similarly reciprocated by gearing 26. The filaments may be of threadlike or tape-like form and several superposed layers may be deposited.

Abstract: 333,874. Chaffer, C. May 13, 1929. Gyroscopic apparatus.-In order to obtain directional indications from a neutrally mounted gyroscope, the axis of which wanders in azimuth relatively to the earth at a speed equal to -# Sin latitude, # being the angular velocity of the earth, there is provided clockwork, &c. mechanism disposed and operating independently of the gyroscope and capable of being regulated so as to apply to the indications derived from the axis of the gyroscope a correction such as to eliminate the effects of the wandering of the said axis. In one arrangement the gyroscope operates a follow-up member in the usual way and there is provided a second follow-up member which receives the movements of the main followup member and also receives the correction applied by the clockwork so that its plane remains in constant azimuth relatively to the earth. Alternatively the clockwork may be made to move the lubber ring. Where repeaters are used the transmitter may be controlled jointly by the gyroscope and by the clockwork so that the necessary corrections are applied to the repeaters: or the correction may be applied directly to each repeater instead of to the transmitter. The correcting mechanism shown comprises clockwork in a case A driving a spindle D on which is mounted a sphere B. A disc C mounted in a fork E is driven frictionally by the sphere, the fork being pivoted about an axis G so that it can be turned to vary the speed of the disc in accordance with the latitude shown on a scale P. The rotation of the disc C actuates a relay within a box M and the relay controls a follow-up motor.
