Title: Improvements in Machines for Forming, and Finishing the Edges of Lenses
Inventor: WEST JAMES
Filed: 1901-05-14
Granted: 1901-08-10
Abstract: 9963. West, J., Raphael, H. J. W., and Ettinghausen, H. L. May 14. Lenses, spectacle &c., bevelling. Relates to improvements on the invention described in Specification No. 13,357, A.D. 1898. Figs. 1 and 2 show views at right - angles. The internal meeting edges a' of the moulds a, a', in which the grinding is effected, are in a plane inclined to the shaft c, or, if at right-angles to this shaft, the edge is interrupted by pins. The halves a, a' of the mould are mounted in the ends of sleeves b<1> which are moved simultaneously in opposite directions by a handle d', acting through a pivoted arm d<1>, and links d' on levers d<3> carrying the sleeves b<1>. The shaft c, mounted between centres, is driven from the shaft q, by a band t on pulleys p, c'. The shaft c, having been started, is automatically stopped when a certain number of revolutions have been made by the following mechanism :-A scroll on the pulley c' drives a pinwheel e on a shaft, on the other end of which a worm-wheel e<3> is mounted to drive a screw f fixed between centres : parallel with the screw f<1> are guides j upon which a monkey i<6> is adapted to slide. This monkey is fitted on opposite sides with spur-wheels i, i<1> which engage with the screw. Normally the wheels i, i<1> are prevented from rotating by brake blocks, which are forced apart by a wedge i<12> on an arm i<13> held up by a catch i<18> pivoted at i<19> and made with a tail arm i<23>. As the shaft c, therefore, rotates, the wheels i, i<1> of the monkey i<6> being locked, the monkey ascends on the screw f<1> until the arm i<23>, striking against an adjustable stop j<2>, liberates the catch i<18>, and thus the locking-wedge i<12>. The monkey then falls upon crossheads k<1>, k<2> sliding on the guides j and resting upon the upper end of a rod l, the lower end of which rests upon one end m of a bell-crank lever. The other arm of this lever forms a catch to engage with one arm n of a three-armed lever on a clutch shaft o. When, therefore, the arm n is liberated by the depression of the rod l, the spring n<4>, coming into action, rotates the shaft o, and thus throws out of engagement the clutch which locks the driving-pulley p to the shaft q. The third arm n<2> operates a pawl s<2>, which effects through an arm i<22> the re-locking of the arm i<13> by the catch e<18>. This automatic releasing-mechanism is fitted to each grinding- shaft. The bolts which secure the lens holders to the shaft c are passed through radial holes which only bear on the bolts at the ends. Abrasion is thus minimized.

Title: Improvements connected with Enclosed or Open Electric Arc Lamps.
Inventor: MENSING LOUIS CARL HENRY
Filed: 1901-11-16
Granted: 1902-11-13
Abstract: 23,225. Mousing, L. C. H. Nov. 16. Arc lamps.-Brake regulating-mechanism is constructed as shown, for use with the arc either open or enclosed. The frame of the lamp includes two uprights 3, and three depending tubes and a plate, 16. The weighted upper carbon-holder 24 and the lower holder slide on and in the tubes 26, 27 respectively, and have arms engaging slots in the third tube. The holders are hung by flexible conductors from opposite sides of two pulleys on an axle 2. One pulley has a cylindrical periphery 1 to serve as a brake-wheel, which is situated between the inturned ends of arms 6 of a plate 4, and a curved plate 7. The plate 4 is slotted, to slide across the axle 2, and the plate 7 is held loosely on the plate 4. A cam 9 is pivoted on the plate 4 ; when the cam is raised, it forces the curved plate 7 against the wheel 1, the ends of the arms 6 of the plate 4 being at the same time drawn against the opposite side of the wheel. The cam 9 is connected adjustably to a regulating-lever 10, which is fulcrumed on the uprights 3, and carries a counterweight 14 and the core 11 of a series solenoid. The curved plate 7 may be omitted, the cam 9, then bearing directly against the wheel 1. The upper carbon only may be movable. The action of the regulating-mechanism is sufficiently energetic to allow the upper carbon to be passed through an asbestos packing-disc into an arc-enclosing globe. The lever 10 may be omitted, the cam 9 being connected directly to the movable core of the solenoid ; the cam may be formed to move the wheel in either direction.

Granted: 1902-07-10
Abstract: 24,220. Ransford, R. B., [Niclausse, J., and Niclausse, A.]. Nov. 28. Feedwater, heating; superheaters, steam.-Relates to heat exchangers in which the system of circu- lation and of jointing of the parts as employed in the Niclausse boiler is used. The heat exchangers may serve either to heat feedwater, to condense or superheat steam, and the examples of heat exchangers given in the Specification comprise feedwater heaters for boilers or other purposes, exhaust steam condensers, steam superheaters, and evaporators such as are suitable for evaporating sea water to produce fresh water for drinking purposes or for feeding marine boilers. (1) Feed- water and other heaters. The heater, Figs. 1 and 3, comprises a number of tubes D of the type used in the Niclausse boiler, the collectors or headers A with or without transverse partitions a, and the casing with the detachable doors or lids J and a non-conducting covering. The feedwater enters by the pipe B and passes from one collector to another by the tubes and leaves by the pipe C, while steam is admitted by the pipe K and together with the water of condensation leaves by the pipe L. (2) Steam superheaters. The super- heater is generally placed in the assemblage of boiler tubes, dividing the tubes into two groups. Steam from each group passes to the drum, then to the superheater, and to the steam pipe. The superheater, Fig. 4, consists mainly of Niclausse tubes H and of headers J. Steam passes from the boiler into the fore compartment a of the header, then into each of the directing tubes, to the compartment b and to one or more other headers if desirable. Several collectors or headers may be coupled together and superposed.

Title: Improvements in Apparatus for Automatically Controlling the Discharge or Feed of Sewage or other Liquid into Bacteria Beds or Filters, Tanks or the like
Inventor: GRAHAM JOSEPH
Filed: 1901-12-18
Granted: 1902-10-30
Abstract: 25,893. Graham, J. Dec. 18. Sewage and foul waters, treating; filtering; bacteriological processes; tanks.-Relates to apparatus for automatically controlling the supply of sewage or other liquid into bacteria beds, or filters, tanks, and the like, and consists of means for shutting off the supply to a filter as soon as it is filled and opening the supply to the next filter. The main supply channel a<1> communicates with each filter k by a passage a<2> leading to a chamber a, in which is a valve c over a passage a<3> leading to the filter. This valve is raised by the descent of a float g of superior weight guided in a chamber b and connected with the valve c by adjustable rods f and a lever d pivoted at e. When the filter is nearly full, it overflows by a siphon into the chamber b, and thereby the float g is raised and the valve c is closed. A projection d' on the end of the lever d, which moves in guides n, as it rises, pushes the arm m of a balance lever out of the vertical until it has passed the catch m<3> on the lever m. This catch then retains the lever d in its highest position, and keeps the valve c closed while the filter is emptying. When the next filter is nearly full, a hinged striking piece d<2> on its lever d closes two contacts t, and thereby completes the circuit of the electromagnet s of the first filter. The lever m, which is connected by a rod p with the armature r, is thereupon moved so that its catch m3 liberates the lever d. The float g then falls, and opens the valve c for recharging the filter k. The electromagnets may be used for stopping the engine which operates the pumps supplying the sewage, when the filters are full.

Title: Improvements in or relating to Apparatus for Automatically Signalling and Stopping Trains.
Inventor: HOFMANN ANTON
Filed: 1902-04-17
Granted: 1903-04-09
Abstract: 8972. Hofmann, A. April 17. Signals on engines; stopping engines and trains; signalling and communicating between trains; indicating and recording movements of trains; lamp signals; audible signals ; contacts, electric.-A conducting-wire K, interrupted at the ends of each section, is arranged along the line, and is engaged by a sliding or rolling contact T on the train Z, the contact T being connected to earth through the detector lamp g*, relay R, generator E, and lead e<2>. In each signal cabin, green and red lamps g, r, and bells lg, lr in parallel with the corresponding lamps, are provided in connection with the conductor K, similar signals being provided in connection with the conductor K' of the other line, so that the particular signals operated show the direction of movement of the train. The lamps g and bells lg are connected through relays b to the advance ends of the conductor sections K, the lamps and bells r, lr being connected through similar relays a to the rear ends of the conductor sections' Both sets of signals have a common earth connection, and can be cut out by the contacts m, n controlled by the track relays of the sections on either side of that occupied by the train. The relay R is of greater resistance than the track relays, and is inoperative when the current passes through it in series with the latter. With the train Z in the section 2 travelling towards the block station B from the block station W, the current from the generator on the train passes through the relay R (without operating it), lamp g*, contact T, and wire K, from which it passes through the relay b, lamp g, and bell lg of the station B, and through the relay o, lamp r, and bell lr of the station W. If, however, either of the sections 1 and 3 is also occupied, or becomes occupied, the relays a, b short-circuit the current through the earthed leads e, so that the relays R on the trains become more powerfully energized, and attract their armatures w<1>, the movement of which is utilized through suitable mechanical or electric means, to apply the vacuum brakes, or to sound the steam whistles or other alarm signals on the trains. The current is preferably taken from an accumulator charged by a dynamo driven from one of the axles, and the accumulator may also be employed to light the ordinary train lamps f.
