Granted: 1900-08-04
Abstract: 10,579. Siemens Bros. & Co., [Siemens & Halske Aktiengesellschaft]. June 9. Points and switches, railway. The point tongues Z<1>, Z<2> are connected by a bar carrying two locking hook levers H<1>, H<2>, which are connected to a crank K by the rods G, so'that, when the crank is driven by worm gearing from the electromotor M, the points are unlocked, thrown, and locked again by one or other of the hooks engaging with the corresponding stop R', R<2>. The motor has a winding for each direction connected to the cabin switch U<2> by supply leads I, II, a common return IV, and another conductor III. A cam-groove on the crank gear throws the switch U<1> over the contacts shown, of which k<1>, k<2> overlap, so that, in the intermediate position of the switch, both circuits are open for current from the switch U<2> in order that the points may be reversed before the throw is completed, if necessary. Near the end of the stroke the motor is short-circuited, so as to stop quickly, by the switch C bridging the contacts k<12>, but, at the beginning, when the switch U' is operated, this switch arm C is pressed back and held by a catch F. The catch is liberated by the magnet E, supplied with current at the end of the stroke through contacts k<3>, k4 at the switch U<1>. The switch arm C carries an indicator T, which shows when the points are in motion, as the arm C is then, out of the normal short-circuiting position. A switch k<5>, k<6>, operated by the switch bar G, distributes current to one or other of the magnets K<1>, K' to connect up the proper semaphore, which may then be operated by an arrangement similar to that for the switch. The safety-bar G<2> is connected to one of the locking-hooks H<1> in this apparatus. In the modified form shown in Fig. 3, both hooks are - formed on one lever H<3> to engage a single fixed block R and to operate the signal distributing- switch U<3>.

Title: Improvements in Machines for Cutting Toothed Gear Wheels.
Inventor: BILGRAM HUGO
IPC: B23F23/12
Filed: 1900-12-13
Granted: 1901-02-16
Abstract: 22,746. Bilgram, H. Dec. 13. Shaping.-A machine for shaping toothed-wheels has a ram g, Fig. 1, driven by an adjustable crank e on a pulley d, and carrying a tool-holder h. The blank n is carried by a spindle u in a bearing p mounted on a segmental plate q. A cone s, corresponding to the pitch cone of the blank, is attached to a housing r, which is connected to the spindle o during the forward stroke of the tool only. The plate q is slowly rotated about a vertical axis by worm gearing 26 driven by a cord 23 from the main shaft c. As the plate q moves round, the cone is rotated, as if it rolled on a plane surface, by bands t connected to opposite sides of the cone and to the body of the machine. This rolling motion causes the tool to generate the tooth surface by taking successive cuts in successive tooth spaces, the blank being rotated one space during each back stroke of the tool. The spacing apparatus, mounted in the housing r, is driven by gearing u, v and a flexible shaft w, Fig. 4, from the main shaft, the gearing being proportioned so that the flexible shaft drives the worm-wheel y at half the speed of the main shaft. The wheel y has two rollers 2, 2<1>, which alternately engage with grooves 3, 4 in a disc 5, the result being to impart to the disc an intermittent rotation of a quarter of a revolution during each back stroke of the tool. By means of change gearing 9, mounted outside the housing, and the spacing- pinion 13 and wheel 14 inside, the movement of the disc is caused to advance the wheel blank one space. The spindle 10 carrying the spacing-pinion also carries a notched disc 21 engagad by a locking lever 18, which is released at the commencement of each back stroke and re-engaged at the end by means of a double cam on the end of the spindle 15 carrying the worm-wheel y. This locking and unlocking ensures that the spacing-apparatus acts only during the back stroke, and that the blank has a rolling movement only during the forward stroke. During each back stroke the tool is raised clear of the teeth by a cam-operated lever k engaging an arm l on the tool holder. To start cutting, the blank is rolled to one side, so that the tool i just touches the circumference. The spacing and slow rolling movements then continue till the tool ceases to touch the blank, having cut one side of the teeth. The tool is then re-set, and the spacing-pinion angularly adjusted on its spindle so that the tool may cut the remaining side. In the machine described, the blank is subjected to a movement relatively to the tool as of a rolling cone to cut bevel teeth, but spur teeth may be cut by giving the blank a movement as of a rolling cylinder, and, if the axis of the blank is inclined to the line of movement of the tool, spiral wheels may be cut. The invention may be applied generally to gear-cutting machines.

Gas and explosive-vapour engines.-Petroleum, benzene, &c. kept at a uniform height in the vessel c is splashed by a paddle h on to the gauze l<1>, through which air is drawn from the pipe i into the cylinder. To regulate the carburetting, the amount of liquid that reaches the gauze is regulated by a wing valve or baffle l, or the air pipe is covered more or less by a valve. The speed of the engine may be controlled, especially when used on a motor car, by altering the angular position of the exhaust-valve cam 5 by adjusting the pinion t of the epicyclic gear t, u, v through which it is driven. The timing of the ignition can be adjusted by altering the angular position of the insulated disc 10 carrying one of the ignition terminals 8, by means of a lever 11 operated by hand or the governor. The speed-regulating devices may be used with gas engines.

Abstract: 9775. Imbs, J. A. A. May 10. Spindle apparatus. -Relates to ring throstles, in which the upper spindle bearings are replaced by rollers b in a box c. The lid i of the box is provided with flanged openings j for the spindles, the flanges projecting within the overhanging lower portions of the wharves. The box is carried by vertically-sliding brackets d, which may be lowered for cleaning purposes by means of a shaft f, which is connected with the brackets d by chains g and lifting-pokers h. The pivots of the rollers b are arranged in a trough m, which may contain lubricant. Beneath the box c is a bar o carrying sliding wedge-shaped latches or blocks p, which may be forced between the spindle and the bar for the purpose of stopping the spindle for piecing-up &c., the spindle being simultaneously forced against the guard plate r or against the sides of the apertures s in the box c. In order to allow of the slight lateral movement of the spindle necessary for stopping purposes, the footstep bearing t is placed loosely in its carrier, and is prevented from rotating with the spindle by means of a pin V. In order to prevent the spindles from being removed when doffing the cops, and also to allow of the removal of the spindles when desired, a sliding bar X is caused to engage with grooves W in the spindles, the bar being provided with notches or recesses at intervals which may be brought into line with the spindles when it is desired to remove them.
