Patent GB-189728869-A (GB)
Title: Improvements in Prism Plates for Windows and the like.
Inventor: EWEN JOHN MEIGGS
Filed: 1897-12-07
Granted: 1898-04-02
Abstract: 28,869. Ewen, J. M. Dec. 7. Ornamenting; moulding. - Glass plates for windows &c. are formed with prisms C on the inner sides for the purpose of directing the rays of light in the required direction, and raised or recessed geometrical or ornamental patterns or designs D, E are formed on the outer surfaces of the plates. This breaking up of the outer smooth surface of the plate prevents the glared or glazed appearance which is sometimes presented by large uneven or strained surfaces of glass. In making the plate, molten glass is placed in a mould provided with a ribbed bottom, and the ornamental pattern is produced by a die or plunger. On raising the plunger, the cooled ribs or raised portions of the design form a kind of grid or network, and tend to prevent running of the hot glass, and distortion of the plate.

Title: Improvements in Acetylene Gas Generators.
Inventor: BOURNONVILLE EUGENE
Filed: 1898-01-13
Granted: 1898-03-05
Abstract: 1013. Bournonville, E. Jan. 13. Acetylene.-The carbide, in separate charges, each capable of producing nearly sufficient gas to fill the bell holder D', is placed in the compartments of a wheel H which is mounted in a casing G. The bottom of each compartment is hinged and is supported by a catch which is tripped by a projection on the casing G opposite the shoot I, I<1>. When the holder bell D<1> descends to a low position, a pawl e<1>, carried by a rod e rising from the bell, engages a ratchet-wheel F on a shaft F<1> which gears by a pinion F' with a wheel J on the shaft g of the wheel H. The latter is thus rotated so as to open a fresh compartment over the shoot I. The carbide falls into the water, and is deflected from beneath the shoot for preventing the gas produced from escaping thereby. The water tank A<2> has fitted in its top a ring B covered above and below by layers of cloth b, b<1>, between which are carried layers of powdered charcoal, and tannin saturated with caustic potash solution, for filtering and purifying the gas as it passes up into the holder. The pieces of carbide are coated with nil for protecting them from the atmosphere. The oil is detached in the water and rises to the surface, forming a layer a. The ball A', which is lighter than water but heavier than oil, serves to close the outlet a<1> and prevent the oil from escaping when the apparatus is being cleaned out. The pipe A<2> serves for the passage of air into or out of the generator when water is being drawn off from or run into it.

Title: Improvements in or relating to Cyclometers or like Registering or Recording Mechanism.
Inventor: LEUCHTER ARTHUR AUGUST HERRMAN
Filed: 1898-01-25
Granted: 1898-07-30
Abstract: 1988. Leuchter, A. A. H. W. Jan. 25. Counting-apparatus. - The casing of the apparatus is lined with celluloid or the like to exclude moisture, the lining being held by screws and flanges. The spindle of the star-wheel a<20> carries a pinion a<22> meshing with idlers a<23>, a<23> on a fixed plate a<10>. These idlers gear with an internally-toothed ring or disc a<24> having an eccentric pinion a<25> meshing w th two internally-toothed rings a<18>, a<17> differing by one tooth. The former of these is fixed, and the latter slowly rotates and with it the shaft a<16> to which it is fixed. A nut cap a<28> closes the star-wheel spindle bearing, and a spring a<29> acting on the collar a<27> gives the requisite friction to prevent over - driving. Numbering- wheels a<30>, a<31>, a<32>, a<33> are mounted on a sleeve a<14>, which is connected also with an enclosing-flange a<13>, and the driving-wheel a<34> is fixed to the shaft. The sleeve a<14> is formed with a series of projections a<35>, Figs. 8 and 10, separated by slots a<36> in which the wheels turn and are held against lateral displacement. Each wheel has an internallytoothed ring a<43> with which an eccentric pinion a" on the wheel of next lower denomination gears and normally runs idly. The next wheel also carries a loosely-pivoted dog a<40> which, when passing the projection a<35>, holds the pinion a<42> against rotation (see Fig. 8), and connects the two wheels for one-tenth of a revolution. The wheels are held snugly in place by a heavy split ring a<44> sprung over the shaft, and springs engaging scalloped wheels prevent any accidental displacements. The additional numbering-wheels a<48>, a<49>, a<52> are for recording daily runs and are set to zero when required without altering the main counter. The wheel a<52> can be fixed by friction to the shaft by turning the button a<63> of a screw clamp ; but when the day-trip register is to be zeroized, this screw is released and the button a<54> is turned, carrying with it the wheel a<52> and so setting the wheels to zero.

Title: Improvements in Governors for Air Compressors Driven by Electric Motors.
Filed: 1898-11-08
Granted: 1899-01-14
Abstract: 23,534. British Thomson-Houston Co., [Libby, S. H., and Potter, W. B.]. Nov. 8. Fluid governors.-Relates to pneumatic governors for air compressors driven by electric motors, and consists of means for controlling the electric motor automatically by a switch arrangement actuated by mechanism sensitive to variations in air pressure. Fig. 1 shows a part elevation, and Fig. 2 a median sectional view, of the governor. The switch contacts D mounted for oscillatory movement on iron fingers D' on, but insulated from, the shaft H, make or break contact with the fixed brushes C, according as the motor requires accelerating or retarding. The forked arm J, to which is hinged the piece J<1>. is rigidly mounted on the shaft H, and through J<1> imparts the motion of the piston N<1> to the shaft H. The arm K and spring K<1>, arranged as shown, act on the piece J<1>, and tend to keep the piece J<1> in that position in which the arm K is stopped by the projection A<5> on the base A. The main piston N<1> and cylinder N are for actuating the switch, and are related to the auxiliary piston O<1> and cylinder 0, and to the exhaust valve T controlled by the auxiliary piston O<1> and spring-pressed plunger T', as shown in Fig. 1. A rod Q, having a collar P<3> and screwed at one end into a nut Q<1> to which a spring P' is attached, presses against the piston O<1>. The pin 0' acted on by the springs O<4> and O<5> serves as a valve between the auxiliary cylinder O and the main cylinder N. On the right side of the casting M, a strainer V<2>, to prevent dirt from entering the governor from the pressure pipe V connecting the governor with the air-receiving tank, is mounted. Above the switch mechanism the coil B of the blow - out magnet is placed, receives current from a part of the contacts on the switch mechanism, and energizes the magnet for interrupting the arc formed when the circuit is interrupted between the stationary brushes C a n d the movable contacts D. Preferably a direct - con - nected series motor, which may be belted, should be used. Under normal conditions, the air pressure in the auxiliary cylinder 0, acting against the pressure of the spring P<3>, keeps the switch mechanism closed, and so maintains the motor driving the air-compressor. When the air pressure becomes greater or less than the normal, the piston O<1> moves down or up, causing the pin O<2> to be withdrawn from the valve S, or the lever R to open the exhaust valve T, and so cause the piece J<1> to move up or down. A quick-acting mechanism for operating the switch is also described. The main and auxiliary cylinders are formed in one piece, and bolted to the base in such a manner as to be easily removed without disturbing the switch mechanism.

Patent GB-189912762-A (GB)
Title: Manufacture of Chlorindigo.
Inventor: IMRAY OLIVER
Filed: 1899-06-19
Granted: 1900-03-24
Abstract: 12,762. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. June 19. Dyes, artificial.-o-Chlorindigo is produced by acting upon a mixture of o-chlor-o-nitro-benzaldehyde and acetone with an alkali, alkaline carbonate, or alkaline earth. For example, a 1 per cent. solution of caustic soda is added by drops to the said mixture, while it is being cooled and stirred, until a blue colouration appears, stirring is then continued for 10 hours, the condensation product thus formed is filtered off and dissolved in a little pure acetone, and the solution is run slowly into dilute caustic soda lye, whereupon the chlorindigo commences to precipitate. The product is more easily reduced in the hydrosulphite bath, and it yields purer and more powerful tints upon wool and cotton than natural or ordinary synthetic indigo. The o-chlor-o-nitrobenzaldehyde employed in the process is produced from o-nitrotoluene by chlorinating it, brominating the resulting chloronitrotoluene, and then converting the o-chlor-onitrobenzyl bromide thus obtained into the corresponding alcohol by hydrolysis and oxidizing the alcohol. Or the chloronitrobenzyl bromide is combined with an aromatic amine, and the product is oxidized to the corresponding benzylidene compound, which is then decomposed by acids. The aldehyde melts at 70‹-71‹ C., and is sparingly soluble in water but easily soluble in most organic solvents.

Title: Improvements in or relating to Lubricators.
Inventor: BOULT ALFRED JULIUS
Filed: 1899-08-05
Granted: 1899-11-25
Abstract: 16,081. B o u l t, A. J., [Michalk, W.]. Aug. 5. Lubricators.-Relates to a lubricator in which one or more pistons m are forced downwards by a screw spindle b. Adjustable bearings d, d<1> are placed at the ends of the spindle, so that wear can be taken up without altering the position of the ratchet-wheel e. The spindle b is worked backwards, for re-charging the cylinders, by turning the spindle z<1>, geared to the spindle b by wheels z, x. The worm f is driven by a ball ratchet, and, in order to ensure reliable working, even if a ball or ratchet tooth should break, two or more ratchetwheels g are coupled side by side as shown in Fig. 3. The partitions h prevent fragments of a broken ball or tooth from interfering with the action of the other ratchets. The ratchet-wheel drives the worm f through a clutch which is thrown out of gear as the piston m nears the bottom of the cylinder, the projection v on the crosshead w striking against the arm q<1> on the rod q which operates the clutch. The worm-wheel e is connected with the spindle b by a bolt operated by a pawl. The nose of the bolt engages projections on tho inside of the wheel e, the parts being so shaped that accidental disengagement is prevented. The delivery passage is provided with a safety-valve to prevent damage to the apparatus in case of stoppage. To prevent lubricant from being sucked out in case a vacuum is produced, in lubricating a steam engine for instance, the passage is fitted with a valve which closes when a vacuum occurs. A narrow passage permits some lubricant to pass even when the valve is closed.
