Title: Method of Making Alkali Hydroxids.
Inventor: SADTLER PHILIP BRIDGES
Filed: 1908-01-04
Granted: 1908-08-06
Abstract: 273. Sadtler, P. B., and Sadtler, S. P. Jan. 4. Caustic alkalis; oxides of sulphur.-Caustic alkali is produced from an alkali sulphate by mixing it with alumina, the mixture being preferably first made into a paste with water, and by dehydrating by heat. The material is then preferably ground and roasted with free access of air, or with a slight suction, and oxides of sulphur are evolved and alkali aluminate is formed. The aluminate is leached out, filtered from excess of alumina, and then decomposed by agitation and again filtered from alumina. The remaining aluminate is precipitated by means of milk of lime, and caustic alkali remains in solution.

Title: Improvements in or relating to Carburetters for Internal Combustion Engines.
Inventor: WELSH TOM
Filed: 1908-08-28
Granted: 1909-02-18
Abstract: 4667. Welsh, T. Aug. 28. Gas. or explosivevapour engines, carburetting in. The air entering t b e carburettor is divided into two streams, one of which flows past the nozzle to form the mixture, the other being diverted from the nozzle to act as supplementary air. The flow of air past the nozzle A, is regulated by disks B, C with partitions D, E to form tortuous passages. The disk C is fixed to the nozzle A, but the disk B can be adjusted through a rod H and nut J. The increased resistance offered by the tortuous path on an increase of speed, prevents the mixture from becoming too rich, as more air flows through the by-pass, which may be formed by a casing concentric with that of the carburettor, instead of being inside the carburettor as shown. In the construction shown, the throttle valve G nearly closes the by-pass and so facilitates starting.

Inventor: BERESFORD ROBERT
Filed: 1908-03-24
Granted: 1909-01-14
Abstract: 6588. Beresford, R. March 24. Motor road vehicles.-Relates to variable - speed gearing of the class comprising three epicyclic parts, a driving-element, a variably driven element, and a controlling-part operated automatically through auxiliary friction or other gearing. Improved means comprising a yielding coupling is employed to effect the automatic control. In Figs. 1 and 2 is shown a form suitable for motor-vehicles, but application to cycles &c. is also mentioned. The epicyclic train comprises a casing 1 carrying pairs of intermeshing planet-pinions 4, 4<1>, which mesh respectively with a sun-pinion 2 upon the engine shaft 5, and with a sun-pinion 3 loose upon the shaft 5 and connected by a sleeve 9 and jaw coupling with a hollow driven shaft 10. A sleeve 13 slidable on a feather &c. on the shaft 10 transmits power to a hollow propeller shaft 16. A countershaft 20 driven from the shaft 16 by chain gearing 19 carries a feather-mounted pinion 21, which can be traversed across the face of a disk 22, driving that disk variably. The variable speed of the disk 22 is imparted through worm gearing 12, 11 to the casing 1, which is the controlling-part of the epicyclic train. The pinion 21 is operated automatically by means of inclined surfaces 14, 15 transmitting the drive from the sleeve 13 to the shaft 16. Axial thrust on the sleeve 13 is resisted by a spring 17, which yields to an extent varying with the load. The consequent axial displacement of the sleeve 13 is communicated through a pivoted lever 25, collar 30, and rods 31, to the pinion 21. Modifications are described employing three-element spur-and-bevel epicyclic trains.

Title: Improvements in Safety Devices for Preventing Overspeed and Overwinding in Hoisting Apparatus.
Filed: 1908-04-07
Granted: 1908-09-17
Abstract: 7664. Fraser & Chalmers, and Whitmore, F. L. April 7. Lifts ; ovenwinding, preventing.-In automatic stop-gear for hoisting- apparatus of the kind described in Specification No. 29,424, A.D. 1904, mechanism is provided for stopping the engine if the speed should become excessive during the period immediately before the end of the wind. The modified mechanism is shown in Fig. 1. The nuts D which traverse the vertical rotating screws C are fitted with projections adapted to engage a notched arm U, which is so connected by links and levers to the governor sleeve that, in the event of excessive speed, the arm U is placed in the path of the nuts D. The arm is pivoted to a lever V on the spindle S, which also carries a notched plate H<1> and a locking-pawl h. When the nut D strikes the notched arm U, the spindle S is rotated, causing the pawl h to disengage from the lever j, which is then sprung over by a spring so as to throttle the engine and apply brakes. To prevent accidental disengagement of. the pawl h, the plate H<1> has a notch on its upper side engaged by a bridle lever R, from which are suspended two pins R<2> in the path of the nut D, so as to disengage the bridle lever before the nut reaches the notched arm U. If the load is being raised at normal speed, the nut D passes the arm U and is freed from its vertical guide, so that it rotates with the screw D and engages the arm H, thereby rotating the spindle S and stopping the engine. If the screw C still rotates, the nut D engages the bevelled underside of a lever r' which is mounted on the same pivot as the bridle lever R. The lever r<4> acts as a guide for the nut after it has left the vertical guide and prevents backward rotation of the nut when the motion is reversed. The notched arm U is drawn upwards by a spring, and its position is adjusted by a screw W.

Title: Improvements in Dobbies or Head Motions of Looms for Weaving.
Inventor: HOLLINGWORTH EDWARD
Filed: 1908-06-04
Granted: 1909-03-11
Abstract: 12,110. Hollingworth, E. June 4. Loom dobbies ; change-box motions.-In head motions of the Hollingworth and Knowles type, the pattern surface f acts on weighted levers g, which are guided in a grate h and control sliding bars k, and levers m connected to the vibrator levers c<1>, a raised lever g allowing a corresponding bar k to be drawn forward by its spring l and move the shoulder m<2> of a lever m into the path of an oscillating knife n. The corresponding vibrator lever c<1> is thus raised, and its gear c is placed in mesh with the upper cylinder gear. When a lever g falls, its finger g' or extension acts on the heel k<1> of the corresponding bar k and moves it away from the corresponding lever m. A bar k in its forward position engages beneath the shoulder or offset part m<2> of the corresponding lever m and retains this lever in a raised position until the pattern mechanism causes the bar to be moved to the left. The lever m in this case falls, and is moved inwards about its pivot pin z, by means of the heel or projection m<3> coming into contact with a fixed shoulder or bar, or set-screw r. The upper end of the lever m then passes under a locking plate or bar s, where it remains until the corresponding bar k is again actuated. The bars k may be supported in grates or grids i, and they may be moved from the levers m by the springs l, instead of vice versa as described above. The knife n may be oscillated by a crank n<2>, arm p, and cam o. The levers m are guided by forked guides j<1>.

Abstract: 5545. Gilbert, B. A., and General Electrical Display Co. March 8. Reel and web apparatus. - A displayapparatus, in which a sheet is wound with intermittent motion from one drum on to another, is driven by a reversible motor arranged, when operating in one direction, to move the screen, and, when operating in the other direction, to move the means controlling the reversing-device. The motor is geared to a shaft 41, Figs. 3 and 8, and, when rotating in one direction, drives a shaft 26 through ratchet and chain gearing 43, and 27, 28, respectively. The shaft 26 is connected to one or other of the drums 13 carrying the band by clutches 30. These clutches are connected by a yoke 24, and are operated by stops 35 on a chain 34 tripping arms 33. The clutches drive through shafts 19, and bevel and ratchet gearing. The band is in sections which are secured together by strips 12<1>, 12<2>, Fig. 2a, each strip being provided with a slot and a headed stud which engage with a corresponding stud and slot in the other strip, screws 12<c> preventing accidental displacement. The strips 12 project from the side of the sheet, and, when the section is in position for display, close contacts 57, 57a, thereby reversing the motor. The motor, when reversed, drives the shaft 38 through ratchet-gearing 42, Fig. 8, spur-gearing 39, and bevel-gearing 38<b>, Fig. 9. The shaft 38 is geared to the shaft of one of the wheels carrying the chain 34, the gearing in the construction shown being mutilated so that the chain may be shortened and operate with a quick motion. The shaft 38 also drives a wheel 41 through ratchet-gearing 49, and this wheel is also driven in the same direction by gearing 41<b>, 41<e>, Fig. 8, when the motor is running in the opposite direction. The wheel 41 carries a cam 50; which depresses an arm 54, closes contacts, and effects the reversal of the motor, the sheet being again moved until the next section is in a position for display. To effect the reversal of the motor, actuation of the arm 54 energizes an electro-magnet 65, Fig. 4, and attracts the armature 60 carrying the moving part 62 of the commutator. A catch 59 retains the armature 60 in this position, the catch being released when an electro-magnet 58 is energized by the closing of contacts 57, 57<a> by one of the strips projecting from the band. The contacts for the lamps illuminating the band are carried by the rocking part 62, so that the lamps are extinguished when the sections are changing. The projecting strips 12, Fig. 2, at the ends of the screen are longer than the others, and close contacts 67, 67' energizing an electro-magnet, which releases the arm of the main switch and stops the motor. The apparatus may be set, to stop after a certain time by arranging a cam, driven by the motor, to close contacts which effect the energizing of the electro-magnet above referred to, and break the main circuit.
