Patent GB-189900571-A (GB)
Title: Improved Electric Arc Lamp Clutch and Feed Mechanism.
Inventor: JAMES HENRY VICENT
Filed: 1899-01-10
Granted: 1900-01-06
Abstract: 571. James, H. V. Jan. 10. Arc lamps.-A clutch for an open arc lamp is constructed as shown in section. The upper carbon a is secured in a holder o on a tube p, which is passed up into a tube b, movable vertically by a controlling- coil. The clutch consists of two india-rubber pads r, adjustable by screws s in levers g, which are hinged to a loose plate i, and pass in inclined directions through slots in a block c, clamped on the tube b. Screws k prevent the levers from leaving the slots. When the tube b is raised, the block c moves the levers inward so that the pads grip and lift the carbon-carrier p; when the tube b falls sufficiently, the plate i is stopped by a part of the frame of the lamp, and opens the clutch. In modifications for enclosed-arc lamps, the carbon carrier o, p and pads r are dispensed with, the screws or plain projections on the levers acting directly on the carbon, which is inserted in a guide sliding in the tube b. The Provisional Specification states that the screws s may have heavy arms which bear on the lamp frame when the clutch is lowered, and which turn the screws inward against the carbon when the clutch rises.

Patent GB-189902490-A (GB)
Title: Improvements in Driving Mechanism for Motor Vehicles.
Inventor: MEES GUSTAV
Filed: 1899-02-03
Granted: 1899-12-09
Abstract: 2490. Mees, G. Feb. 3. Motor road vehicles.-Relates to driving-mechanism for motor cars whereby the power is transmitted to any intermediate shaft, which is driven at different speeds, the rotation of the motor being constant. One form of construction is shown in Fig. 1. Three separate gears, arranged on a common intermediate shaft W, are operated from the motor shaft by bevel gears k, K<1>, K<2>. A suitable number (three being shown) of planetwheels P', P<2>, P<3> engage with the internal wheels J<1>, J<2>, J<3>, and with the outer wheels Z<1>, Z<2>, Z<3>. When one gearing is running without driving, the planet-wheel is carried round the inner wheel, and carries with it a brake-wheel S', say, bolted to it. By braking the wheel S' by the brake B', the power is transmitted through the planet-wheel from the toothed wheel Z' to the shaft W, or from the smaller internal wheel J<1> to the shaft, depending on the speed ratio required The gearings Z<1>, P', J' and Z<2>, P<2>, J<2> are operated by the bevelwheel K<1> running to the right, and the gearing Z<3>, P<3>, J<3> is operated by the wheel K<2> running to the left. If one of the gearings driven by the wheel K<1> be thrown into action, the carriage travels forwards with speed depending on the gear, whereas if the third gear is used the travel is backwards. In the rearward movement, the power is transmitted from the bevel-wheel K<2> through the wheel F to the wheel J<3> and to the planet-wheel J<3> and outer wheel Z<3> to a wheel E mounted on the shaft. The brakes for throwing the gears into action are operated by two levers V, R, Fig. 5, keyed on concentric shafts v, r. The lever V controls the brakes B' and B<2> for the forward gears, and the lever R is the reversing-lever. At any instant one gearing only is in action. Both levers are connected together, so that only one lever, R, need be manipulated in order to throw one gear out of action and to apply the brake for the backward gear. The lever V may, however, be placed to right or left of the lever R independently. These motions are effected by means of toothed segments and pawls. The shaft w is mounted in the planet-wheel shaft W, and chain-wheels p<1> are provided. The differential gear D', D<2>, d<1>, d<2> is such that, when moving in a straight line, the wheels d<1>, d<2> are stationary on the bolts c<1>, c<2>, and in a curve the wheels d<1>, d<2> rotate on the bolts. In another arrangement, for smaller and lighter vehicles in which backward travel is unnecessary, the bevel-wheel K<2>, wheel F, and backward gear are omitted, and a brake-wheel is firmly connected with the shaft W and the capsule N<1> of the differential gear. A jaw brake also is employed instead of the band brake, the brake discs being pulley-shaped, and the brakes are applied or released by means of double levers keyed on the shafts v or r and link bars by the brake levers V and R.

Granted: 1901-08-24
Abstract: 15,188. Parsons, E. Aug. 25. Canals and rivers; weirs.-Relates to an intermittent watercurrent motor, and consists of means for closing the sluice gate or its equivalent until sufficient water to work the motor has accumulated, and then opening the sluice gate for a short time, after which it is automatically closed and the action repeated. The mill-stream a has a vertical cylinder c<5>, from which the water, when it rises to a certain level, can flow through a tube d to the bucket c. The bucket is suspended from a cord e, the other end of which is secured to a weight f heavier than the empty bucket, and the cord is connected to a pivoted lever g carrying a clutch h mounted on the shaft h'. The clutch engages teeth upon the loose pulley i<1>, which is driven from the motor shaft A, so that when the bucket falls under the action of the water flowing into it, the clutch h is thrown out of engagement with the pulley i<1>, and the consequent falling of the weight k<2> rotates the drum k and shaft h<1>, and so opens the sluice b by means of the gearing m<1>, n<1>, o. When the water falls to a certain level, the float c<4> by means of the cord c<2> opens the valve o' in the bucket. When the bucket is empty, it rises under the action of the weight f and in engaging the clutch h and pulley i<1> allows the rotation of the motor shaft to close the sluice b, and to wird up the weight k<3>.

Granted: 1900-11-24
Abstract: 17,686. Wadsworth, F. L. O. Oct. 5. Rolling; moulding.-Relates to the production of large sheets of prismatic glass. Fig. 1 shows the machine in sectional elevation, and Fig. 6 an enlarged section with the die inclined. The machine is mounted on wheels 3 to facilitate its movement to or from the annealing-furnace. Pillars 5 support a box 6, from which extend brackets 7 carrying rollers 8 for the support of the movable spreading table or platen 9. The glass is rolled into a sheet on the platen by means of a roller 19, connected by a cord or tape with the platen so that their surfaces move at the same speed. Within the box 6 is guide the piston-rod 13 of a piston 14 moving in the cylinder 15, to which compressed air can be admitted by a hand-operated valve 58. The piston-rod supports a table 10 provided with side flanges and a centering-rib, so as to receive and position the platen 9 on which the sheet of glass has been rolled. The die 23 which forms the prismatic ribs in the glass sheet when the latter is pressed against it is bolted to a plate 22 adjustably carried by the spring-pressed frame 20. The die is provided with knife-edge cutters 29, which trim the ends of the sheet by entering, as shown in Fig. 6, between the ends of the main portion of the platen 9 and the spring-controlled end-plates 33, which are moved by means of wedge-shaped surfaces on the die to admit the cutters. Rollers 49, loosely mounted on shafts 48, project slightly above the surface of the table 10 when it is in position for receiving the platen, but drop clear of the table when it rises. When the prismatic ribs are under-cut, as shown in Fig. 6, it is necessary to incline the die in order that it may separate from the moulded ribs. This is effected by means of adjusting-bolts 25, and the table 10 is caused to incline to the same extent by means of the adjusting-screw 55. The cavities in the die are vented by holes at the end of each cavity, or they may be formed with one end open. The prismatic glass formed in the above manner can be cut by a diamond or a glazier's cutting-tool in the same manner as ordinary glass.
