Title: Improvements in Switching Apparatus for Transformers for Alternating Current Systems of Electrical Distribution.
Inventor: OXLEY EUSTACE
Filed: 1897-12-07
Granted: 1898-01-29
Abstract: 28,921. Oxley, E. Dec. 7. Distributing; lighting, systems of; switches; cutouts.-Relates to means for cutting out the primary of a transformer in alternating-current distribution when there is no load on the secondary. Fig. 1 shows an electromagnetic switch for opening and closing the primary circuit ; Fig. 2 shows one form of hand-switch in the secondary circuit and controlling the electromagnets, and Fig. 6 shows one arrangement of the connections. 31 is the high-tension primary coil of the transformer in the circuit of which the switch 10 is interposed. The arms 2 are operated through the toggle-levers 6 and bar 7 connected to the pivoted armature 16 of the magnets 15. M is a meter, and 51 a local battery. The magnets and the battery are connected up to the hand-switch by the wires 48, 49, 50 as shown. When the handle 36<a> is depressed, a projecting piece 47 strikes the spring contact 43, forcing it against the contact 46 and completing a momentary circuit through the magnets 15 and pulling over the armature to close the primary circuit as shown in Fig. 1. Immediately afterwards contact is made at 41, so closing the secondary circuit. On opening the secondary circuit, contact is made between 43 and 45 and a momentary current sent through the magnets 14, so breaking the primary circuit. In a modified arrangement, a small transformer replaces the battery 51. Fig. 8 is a diagram showing the arrangement for automatically cutting out the primary when all the translators are switched off and for opening when any one is switched on. A small electromotor 62 is arranged in the secondary circuit, and is half-turned against the action of a spring so long as current flows in the secondary. This motor carries an arm 54 engaging a trip lever 58 adapted to close circuits controlling the magnets 14 for breaking the primary. The hand-switches control only the magnets 15 for making the primary. When all the switches have been opened and no current is flowing in the secondary, the motor 62 rotates under the action of the spring, the arm 54 striking the lever 58 and so completing the circuit of the magnets 14. In a modified arrangement, the motor carries two arms so forming a double-pole switch. This necessitates the duplication of several of the contacts.

Title: Improvements in Dredging Apparatus.
Inventor: O'CONOR MAURICE MARY JOSEPH OW
Filed: 1898-06-02
Granted: 1899-04-08
Abstract: 12,439. O'Conor, M. M. J. O. June 2. Dredging.-A pair of cylindrical vessels 1 are connected together by chains 2 in the manner described in Specifications Nos. 27,047 and 29,412, A.D. 1897, and are provided with lower wedgeshaped tanks or cutting-edges, and central tanks or receptacles 9<a> for receiving the dredged material as the cylinders are drawn together along the river bed or water-way. The loaded cylinders are rotated to bring the openings uppermost by pumping water out of the lower tanks, and the cylinders are raised by pumping water out of the end tanks and the remaining side tanks. The loaded cylinders are towed to any desired place, and are inverted to discharge the spoil by means of hydraulic rams acting on chains or flexible connections which pass under both cylinders, and are attached to the wedge-shaped tanks or cutting-edges. This inverting-apparatus may be used in connection with the wreck-raising apparatus described in the prior Specifications referred to above. The chains 2 are wound up within the cylinders as described in the prior Specifications, or are attached to rods which are fixed to movable hydraulic cylinders, and slide through stuffing-boxes or packing-rings. The cylinders slide between guides on ball or roller bearings, and are connected by slotted links to collars or bearing-rings on the stationary rams. The arms of the cylinders are also connected by pins and slotted links to collar guides or bearings which come into action as the cylinders are forced outwards. To facilitate the rotary movement of the cylinders past one another when they are inverted, they are fitted externally with antifriction balls or rollers. Arms 8, fitted with rollers, keep the cutting-edges at the proper depth during the dredging operation. End water-tight compartments 1<a> carry electric motors, pumps, and apparatus for working the vessels. Air tubes and electric cables 17 from the salvage ship 16 pass through the rounded ends of the cylinders, and chains 18 prevent any undue stress from coming on the cables. Valves or cocks for admitting water to the chambers for the purpose of sinking the vessels are operated by springs and fluid pressure, or mechanically by endless chains, shafts and gearing. Gratings or screens 10<i> prevent the choking of the valves, and the entrance of foreign matter. Air inlet cocks or valves are provided at the bottoms of the tanks 9<a> to facilitate the discharge of the spoil, and are operated by band-wheels, bevel-wheels, and worm gearing. In narrow water-ways, a single dredging-cylinder may be used. In this case, the free ends of the chains 2 are anchored down or secured to fixed points.

Title: Improvements in or appertaining to Automatic Key-board Music Instruments Actuated by Pneumatic Devices.
Inventor: EHRLICH PAUL
Filed: 1900-07-16
Granted: 1901-07-16
Abstract: 12,795. Ehrlich, P. July 16. Automatic instruments.-The invention relates to means for playing keyboard instruments mechanically. The tracker - board and tune-sheet are arranged upon the keyboard, and communicate with flexible diaphragms f below the keyboard by tubes which spread out fanwise and pass between the keys. The diaphragms f are situated in a chamber which is exhausted through a passage j. The diaphragm f is depressed when the corresponding hole in the tracker-board is opened, a valve g is thus opened, and a passage h to the outer air is closed, thus deflating the pneumatic i. This pneumatic i acts on the key c through rods p, and a sector l. To graduate the strength of touch, the rods q may be slotted, the sectors passing through the slots, and, their distances from the centre of their segments being adjustable automatically or otherwise, the motion communicated to the key can then be altered. The tune-sheet is wound off a roller 1 on to a roller 2 during the performance of a piece, and is re-wound automatically at its conclusion. The device for doing this is shown in Fig. 6. The take-up roller 2 turns freely on the driving-shaft 3, excepting when engaged by pins 7 on a pinion 5 which is splined on the shaft. The movement necessary for this is obtained from a lever 9, which, when moved into the position shown in dotted lines, connects the pinion 5 and the roller 2, at the same time disconnecting the pinion from a pinion 6 which operates the storage roller 1. The re-winding position is shown, in which the storage roller is driven and the take-up roller remains idle. Friction discs may be used instead of pinions. The lever 9 is operated by a pneumatic 10, and means for holding the pneumatic 10 in a coltapsed state are provided by a catch 14 on another pneumatic 12.
