Patent GB-189816157-A (GB)
Title: Improvements in Means for Moving Revolving Tool Carriers, Crank Pins and other Devices in a Direction at Right Angles to their Axes of Revolution.
Inventor: BERGER ERNST MAX
Filed: 1898-07-25
Granted: 1899-05-20
Abstract: 16,157. Berger, E. M. July 25. Tool-holders; boring and drilling; lathes; slotting; planing and shaping.-Relates to means for moving revolving tool-holders, crank-pins, &c. in a radial direction. Referring to Fig. 1, the faceplate b, which may be screwed on the mandrel of a lathe or drilling or other machine, supports a screw e and a sleeve f provided with bevel pinions c, d. Nuts on the screw project through slots in the sleeve and engage with the tool - holders a, which are fitted in guideways on the faceplate. Mounted co-axially with the faceplate are bevel-wheels m, n in gear respectively with the pinions c, d. The wheel n is secured upon a sleeve o provided with an arm by which it is held stationary. The wheel m has fixed to it a worm - wheel q in gear with a worm p provided with a handle by turning which in one direction or the other the screw is caused to rotate in relation to the sleeve, and thereby to move the tool-holders towards or away from the centre. The epicyclic train may be composed of spur-wheels, and worm gearing may be used to connect the screw and sleeve with the spindles of their respective pinions. In another arrangement, the tool-slides are formed with racks which engage one on each side of a toothed ring loosely mounted on the boss of the faceplate, beside another toothed ring of the same size which is keyed on. A spindle mounted in an arm loose upon the boss carries at one end two pinions in gear with these rings, and at the other end two other pinions which differ in size from the first two ; one of these gears with the fixed wheel on the sleeve o, and is formed integral with the pinion which is in gear with the keyed ring ; the remaining pinion gears with the controlling-wheel, and is connected with the pinion which is in gear with the loose ring. In a modification of this arrangement, applicable as a variablethrow crank for cycles, pumps, shaping and slotting machines, &c., the loose toothed ring on the boss of the faceplate is formed in one with a spirallygrooved disc which engages with the grooved back of the slide carrying the crank-pin. Fig. 8 shows another construction, in which the slides a are formed with racks in gear with segments i upon the spindles of which are secured pinions h adapted to gear with a cylindrical rack m. This is formed on the boss of the hand-wheel which works over the screwed stationary sleeve o. A modification of this construction is described in connection with a boring-bar. In another modification, the cylindrical rack is replaced by straight racks which are retained in their proper position upon the boss of the wheel l by grooves in the faceplate ; the wheel l is in this case operated by gearing.

The diaphragm K is made to turn in a mask B, so that the greatest length of the aperture may be turned vertical or horizontal by means of the lever H turned by the external knob J. Modifications are described in which the positions of the diaphragm, mirror, and object lens are interchanged, or the mirror may be dispensed with.

Patent GB-189824851-A (GB)
Title: A New or Improved Rotary Motor.
Inventor: DEFLESSELLE LEONCE
Filed: 1898-11-24
Granted: 1899-09-16
Abstract: 24,851. Deflesselle, L. Nov. 24. Annular - chamber type.-Water, steam, compressed air, or other fluid under pressure, or explosive fluids such as gas, petroleum, and acetylene, act between movable pistons c and the radial vanes of a rotary disc a on the shaft R. The motive fluid enters by way of valves E, controlled by centrifugal governors l, and in the case of gas engines is ignited in explosion chambers d by tubes X, heated to a cherry-red, or electrically. Exhaust takes place through chambers h to a pipe M. Air entering by openings g is more or less compressed, and, being driven into air chambers F having valves as shown, acts behind the pistons c to keep them in contact with the disc a. From the piston chamber the compressed air is led to a central reservoir. If the pressure produced in this way is not sufficient, it may be increased by air pumps. The cylinder B is cooled by water circulated through compartments N by pipes O. In the case of steam engines, steam is circulated through the compartments N.

Granted: 1899-07-22
Abstract: 10,596. D÷mjÚn, J., and Schr÷tter, C. May 19. Targets.-Relates to electrical apparatus for releasing clockwork w h i c h automatically delivers a prize to the marksman when the bull'seye is struck. In the arrangement shown in Fig. 1, the bull's - eye 1 is attached to a spring contactpiece 3, which momentarily completes a circuit 6 through an electromagnet 8 when the bull's-eye is struck and forced back. The electromagnet attracts an armature 9 attached to a hooked retaining-lever 10, and the clockwork stop-wheel 11 is released. The hooked lever is held out of action, until the clockwork is fairly started, by an electromagnet 13 in a secondary circuit 12, which is closed by the lever coming in contact with the metal strips 17. As the stopwheel rotates, a spring contact-lever 15 is released the circuit 12 is broken, and the lever 10 is drawn back by a spring to engage with the next tooth of the stop-wheel. In a modification, the lever 10 is held out of action until the clockwork is started by a stepped lever, aLd the lever 15, when released, completes a circuit through an electromagnet which attracts an armature on the stepped lever. The lever 10 is thereon released, and caused to engage with the next tooth of the stop-wheel. The automaton may deliver any kind of reward, or play a piece of music.

Title: Improvements in Driving and Speed-changing Mechanism for Motor-road Vehicles.
Inventor: CRAIG JAMES
Filed: 1899-09-06
Granted: 1899-11-11
Abstract: 18,051. Craig, J. Sept. 6. Motor road vehicles.-Relates to speed-changing driving-gear, applicable also for reversing, and specially adapted for use with compressed air and gas motors. The gear, together with the moving parts of the motor, is enclosed in, and supported by, a frame or casing which is mounted by means of adjustable eccentric bearings on the driving-axle of the vehicle, so that the motor with its driving- gear may be shifted relatively to the driving-axle to bring one or other of two toothed wheels into gear with a wheel on the axle. In the position shown, the wheel 9 on the motor shaft gears directly with the wheel 14 on the axle. On throwing over the lever 7 the eccentric bearings are turned and the wheel 13 is brought into gear with the wheel 14, which is thus driven at a low speed. In the intermediate position the wheel 14 is free. The intermediate wheels are mounted in plates or webs extending from one end of the casing to the other and serving as strengthening- stays. The motor is supported at the cylinder end by a bar 15 capable of sliding in a bracket 16.

Abstract: 9760. Hookham, G. May 28. Current meters.-A maximum-demand indicator consists of a float n, which is movable about vertical pivots n<1> in a vessel containing glycerine and water, or other viscous liquid, and which carries a pointer m over a scale on the front of the vessel. The pointer and float are movable in one direction by a counterbalanced arm of a galvanometer needle d, which is suspended by a torsion wire and turned by two stationary flat coils a, carrying the current to be measured, or the current from a thermopile, of which one set of junctions is surrounded by a eating-coil carrying the current to be measured. The float moves only slowly, and remains where it is placed by the action of the galvanometer. In the form shown in Fig. 3, the float is pivoted in the angle of a vessel of quadrant form in plan. The "needle" may be a rectangular tube of soft iron as shown ; or two steel bars may be arranged astatically. The float and vessel may be cylindrical, the float being provided with radial vanes, and the vessel with T-shaped partitions. A pivoted lifter may be provided, movable by hand, to support the galvanometer needle during transport.
