Title: Improvements in Piano Players.
Inventor: WARREN CHARLES
Filed: 1902-11-21
Granted: 1903-01-29
Abstract: 25,654. Warren, C. Nov. 21. Automatic instruments.-Relates to piano players, Fig. 4 being a cross-section. The upper part, containing the greater part of the mechanism, is supported by screwed adjusting-rods on the lower, which consists chiefly of a cabinet with shelves, the middle part being cut away to accommodate the blowing- pedals J. The piano pedals are operated by shoes l<4> carried on rods l<2> by adjustable arms L<3>. These are operated by a cross-bar L' carried on a shaft L, which can be turned by a handle l<1>. Either pedal can thus be operated, the other being freed at the same time. A tension equalizer K, Fig. 3, supplies the playing-pneumatics and also the tune-sheet motor. The tension for the latter can be controlled by a valve so as to regulate the tempo. The motor turns a shaft n<4>, which operates sprocket and clutch gearing by which the tune-sheet rollers are driven in either direction. The clutch is operated by an arm Q, which is adjustably connected with a rod Q<1>. This rod is also adjustably connected with its handle Q<5> and again to a valve, the spindle of which is shown at Q<3>, which cuts off the wind from the playing-pneumatics while the tune sheet is being re-wound. The playing-pneumatics are shown at P, P', and actuate arms p, p<1> which strike the keys. The primary pneumatics, which are controlled by a tune sheet and tracker board 0 in the usual way, are shown just behind the pneumatics P, P' in Fig. 4, and separately in Fig. 9. The chambers p<7> are open to the atmosphere and p<6> to the vacuum. The ports leading from the tracker board are covered by flexible diaphragms p<4>, which have small holes 5 for restoring the vacuum in the ports. The valves have cylindrical bodies 2 and rest on the diaphragms. They are covered in by plates P<3>, and control passages P<5> leading to the pneumatics P, P<1>. In order to obtain forte effects, the movable board of the equalizer can be locked by a rod R which is attached at its lower end to a fixed pivot r, and passes through a friction clamp T on the movable board. The clamp can be closed on the rod R by an eccentric, which is operated by a rod controlled by a handle w. This handle also actuates a valve in the wind trunk k<2>, which, when opened, allows the full tension of the vacuum to operate the playing-pneumatics.

Patent GB-190301068-A (GB)
Title: Improvements in Method of and Means for Generating and Distributing Alternating Electric Current.
Inventor: CAROLAN EDGAR ALFRED
Filed: 1903-01-15
Granted: 1904-01-14
Abstract: 1068. Carolan, E. A., [General Electric Co.]. Jan. 15. Dynamos, regulating. - Relates to devices for causing the voltage to remain substantially constant with a change either in the load or in the power factor of the current supplied thereby. An ordinary induction machine 1 has, for example, a stator 2 having a three-phase winding with terminals 3, 4, 5 leading to mains 6, 7, 8 supplying current to such apparatus as an induction motor 9, lamps 10, &c. The rotor 11 has a three-phase winding connected by rings 12, brushes 13, and leads 18 to a low-frequency alternating current exciter 14 having a directcurrent field magnet shown as a rotor 15, mounted upon a shaft 16, and excited by current from a small direct-current exciter 17. The main machine is driven by a belt or the like 20, and the exciter is driven at some relatively definite speed by any device, spur gearing 19 being shown. The machine 14 excites the main machine 1, and the rotor 11 is then rotated in the opposite direction to the rotary magnetic field produced by the current from the exciter. When the speed of the rotor reaches a definite amount, the rotation of the magnetic field ceases ; when it becomes faster, the rotation of the magnetic field changes. At this time, instead of delivering energy to the rotor, the exciter 14 receives energy, and acts as a motor. The fall of potential in the leads 18 is therefore from the generator 1 to the exciter, and, as the electromotive force of the latter is constant, that at the terminals of the rotor winding must rise with an increase of load. The amount of this rise may be adjusted by means of resistances in the leads 18, so that the voltage of the generating- current may remain substantially constant regardless of the variations in the magnitude or in the power factor of the generated currents.

Title: Improvements in Vapor or Gas Compressors.
Inventor: GUTHRIE JOHN
Filed: 1903-04-24
Granted: 1903-06-25
Abstract: 9274. Guthrie, J., [Dubern, G.]. April 24. Stuffing-boxes; pistons.-Compressors for vapour or gas derived from sulphurous acid or other volatile liquid &c., used for refrigerating and other purposes, are provided with improved means for packing, lubricating, and cooling the piston-rods and for packing the pistons. Two stuffing-boxes B, D are used, the annular area of the packing A being twice that of the packing C. The two packings are separated by a differential lantern E, so that, when the upper gland G is screwed down, both packings will be compressed but the intensity of the compression of C will be twice as great as that of A. Any vapour escaping past the packing C will have its pressure reduced, before reaching the packing A, during its passage through the lantern E, which communicates, as shown in Fig. 7, with the low-pressure refrigerator 6 by means of a pipe 1 fitted with a pressure gauge 4 and a reducing-valve 2. The gauge indicates the pressure to which the reducing-valve must be adjusted in order just to prevent the vapour from passing the packing A. To cool the piston-rod, the volatile liquid is circulated through the space Z below the stuffing-box D. For this purpose, when sulphurous acid is the vapour compressed, the space Z communicates by pipes with both the high-pressure vessel or condenser 7 and the low-pressure vessel or refrigerator 6. A filter 16 prevents any foreign material from entering the stuffing-box. Escape of the liquid downwards from the space Z is prevented by a third stuffing-box K. The piston packing-ring consists of a main ring 14 shouldered to receive two auxiliary rings 13, the caps in the ring, being arranged to break joint. Springs 19 aid the expansion of the ring.

Title: Improvements in or relating to Receptacles or Containers for Molten Glass.
Filed: 1903-06-06
Granted: 1904-01-21
Abstract: 12,799. Lake, H. H., [Toledo Glass Co.]. June 6. Crucibles and melting-pots.-Relates to a rotary container for molten glass, which, when a portion of the glass has been withdrawn by the suction gathering-mould &c., is rotated to bring a fresh portion of the metal into position to be gathered, while the portion chilled by the gathering-appliance is carried round to be re-heated. The container G is mounted on a spindle K<1> and is adapted to be rotated by ratchet gearing L &c., the gathering being effected at the part K of the container which projects beyond the cover H and wall I, the cover and wall forming a heating-chamber M above the rest of the container. The molten metal is delivered from the usual melting-tank A, through the passage E, controlled by the shut-off valve P, into the container G. When a portion of the metal has been gathered at K, the container is rotated to bring a fresh portion of the metal into position, the portion chilled by the gathering- appliance being carried round under the chamber M and re-heated. The re-heating is effected by the heat passing from the tank A through the passage E. For working small batches of glass, the tank A may be dispensed with, and the container G heated directly by gas supplied by pipes c &c.
Patent GB-190313808-A (GB)
Title: Improvements in the Manufacture and Production of Derivatives of the Anthraquinone Series.
Inventor: NEWTON HENRY EDWARD
Filed: 1903-06-20
Granted: 1904-03-24
Abstract: 13,808. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. June 20. Anthraquinone and amidoanthraquinone - alpha - sulphonic acids are prepared by treating anthraquinone with fuming sulphuric acid in the presence of mercury or of mercury compounds, such as mercurous or mercuric oxides or salts. Compounds, such as boric acid, may also be added. At first the monosulphonic acid is obtained, but by a more energetic sulphonation the disulphonic acids are obtained. To produce the monosulphonic acid, the anthraquinone is used in excess, and this excess is subsequently filtered off. The potassium salt is eventually thrown down by adding potassium chloride, and forms straw-yellow brilliant leaflets difficultly soluble in water. The free acid is obtained by adding concentrated hydrochloric acid. On heating the acid or its salts with ammonia, the alpha-amidoanthraquinone is obtained, or with an aqueous monomethylamine solution the alpha-methylamidoanthraquinone is formed. In preparing the disulphonic acid, the temperature must not exceed 150‹-160‹ C. During the heating the alpha1-alpha3-anthraquinone disulphonic acid separates as well-formed crystals, whilst the alpha1-alpha4-anthraquinone-disulphonic acid remains in solution. The two are separated by filtration. The solution is run into water, the solution heated, and potassium chloride added, whereby the potassium salt of the latter acid is precipitated as light yellow needles. The two acids may be separated by other means, such as fractional crystallization. By heating either of these disulphonic acids with ammonia or monomethylamine, the corresponding alpha-diamidoanthraquinones or alpha-dimethyldiamidoanthraquinones are obtained. The Provisional Specification states that instead of fuming sulphuric acid, other suitable sulphonating agents can be used.

Patent GB-190315456-A (GB)
Title: Improvements in Machinery for use in the Manufacture of Mosaic or Inlaid Floor Cloth.
Inventor: BATTEN EDWARD
Filed: 1903-07-13
Granted: 1903-08-13
Abstract: 15,456. Batten, E. July 13. Coated fabrics.- Relates to the manufactureof mosaic or inlaid floorcloth by machines in which tesserµ, cut from sheets of linoleum by knives secured to cylinders, are deposited on a backing in contact with an inlaying-cylinder, such as those described in Specifications No. 4986, A.D. 1899, No. 3984, A.D. 1900, and No. 12,155, A.D. 1901. The knives 13, Fig. 1, are held between plugs 1, into which screw bushes 3, adapted to act as guides for the stems 5 of ejectors 9 secured by countersunk screws 10. Helical springs 7, interposed between the bushes 3 and collars 8 on the stems, press inwards the ejectors, and the chambers 6, in which lie the springs, are long enough to allow the ejectors, when drawn fully outwards, to project beyond the edges of the knives 13, and so to permit the removal of any accumulated particles of linoleum. Just before the tesserµ are cut, the ejectors may be additionally pressed inwards by a rotating roller provided with projections. To ensure complete severance of the tesserµ, a rotating roller is so mounted relatively to the cylinder carrying the knives 13, that the knives enter grooves in the roller immediately after the cutting has occurred. When the tesserµ are secured to the backing by adhesive waterproof composition in addition to holding-pins on the inlaying-cylinder, the pins are arranged in circles, and the backing is pressed on to the pins by heated rollers provided with circular grooves opposite the pins. The means, shown in Figs. 3 and 4, for justifying a defective fabric 15, comprise a justifying-cylinder 14, round which the fabric is led under shoots 18 containing tesserµ. The tesserµ are normally prevented from falling out by pins 20 on the ends of springs 19, but any recess in the fabric allows the corresponding spring to open the shoot, out of which one of the tesserµ falls into the recess and is pressed under the roller. The tesserµ are shaken dowu into the shoots by means of the ratchet-released hammers 21, which fall at intervals on to the spring-supported trough 16 containing the tesserµ. When travelling round the justifying-cylinder 36, Fig. 6, the surface of the fabric may be scored to represent woven fabrics, by disc-shaped knives 37 and flat-knives secured transversely to rollers 38. The edges of the knives may be coloured from troughs 39 by means of the rollers 40, 42 and the scrapers 41.

Patent GB-190323992-A (GB)
Title: Improvements in Semi-automatic and Full Automatic Lathes and Screw Machines and Multiple Speed Counter Shaft Arrangement for and in Combination with same.
Filed: 1903-11-05
Granted: 1904-11-05
Abstract: 23,992. Hitchon, A., Bannister, W., and Howard & Bullough. Nov. 5. Lathes; tool-holders; screwing -In a semi-automatic or fullautomatic lathe or screwing- machine, the spindle is driven by helical gearing 3, Fig. 1, from a cross-shaft 1, thus producing a constant end pressure and preventing axial movement of the spindle. The draw-in tube which effects the tightening of the chuck collet is effected by a stiff spring 14 to allow for variations in the size of the stock. The release is effected by fingers 10 and a sliding cone 9, or these parts may be used to effect the tightening, the pressure being transmitted through the spring. The tool spindles 16 of the turret 17 are positively fed and retracted by a yoke 19 engaging an arm 20 on a sliding bar 32, or the yoke and arm may be interchanged. The tool-holders 21, Fig. 8, are held in the ends of the turret spindles 16 by a divided bush 22, 24 tightened by a screw or bolt so that the holder is clamped at three points. The cams for operating the chuck, the wire feed, and the turret spindles are mounted on a single drum 28 driven by worm gearing, the worm-wheel being directly connected to the drum. The sliding bar 32, and similar bars for operating the wire feed and the chuck, have bowls engaging the cams and may be of considerable length to prevent binding. The worm shaft 29<a> driving the drum shaft is driven by a two-speed gear of the kind described in Specification No. 23,515, A.D. 1903, a cam disc 38 operating the belt-shipper. The cross-slides 41 are operated by levers from a cam disc 43, the knuckle ends of the levers engaging in blocks 40 adjustable on the slides to allow the positions of the tools to be adjusted, and provided with coverplates to protect the knuckles from dirt &c. A multiple-speed countershaft arrangement for use with the machine is described as adapted for two and four speeds, but may be adapted to any reasonable number by increasing the number of belt pulleys &c. In a two-speed gear, the slow speed is obtained by a pulley 49, Fig. 11, which drives the countershaft 46 through a roller clutch 51, the belt being normally on this pulley, but shifted to a loose pulley 50 when it is desired to stop the machine. The fast speed is obtained by a pulley 48 keyed on the shaft, on to, or from which, the belt is automatically shifted by a shipper 62 when the fast and slow speeds are respectively required. The shipper is operated by an eccentric 61 frictionally driven by a shaft 54 from the countershaft and locked by a projection on it engaging one or other of two arms 66 on a vertical rod 68, controlled by a cam disc on the lathe and a weighted arm 70 to form an escapement. During each release of the eccentric, it rotates to operate the shipper through arms 60 to transfer the belt fron one of the pulleys 47, 48 to the other.
