Title: Device for Magnetizing Iron by Means of and Alternate Current and Improvements in Dynamo Electric Machines.
Inventor: WALKER MILES
Filed: 1904-12-16
Granted: 1905-12-16
Abstract: 27,424. Walker, M. Dec. 16. Armatures; dynamos, regulating; electromagnets ; field m a g n e t s .- Relates to means for magnetizing iron to obtain constant polarity by alternating currents, particularly applicable to homopolar or direct-current machines for exciting an alternator. Fig. 1 shows the principle underlying the invention. A ring, consisting of parts of which the part 2 is of lower resistance than the part 3, is rotated round the core 1 synchronously with the alternating current supplied through the brushes 4, 5. By this arrangement the core 1 is given constant polarity. The core may be surrounded by a ring 25, Fig. 2, of low resistance. The resistance 3 may be a ring, and the conductor 2 a coil with one or more turns, in the latter case the speed of the rotating element being reduced below that of synchronism. In the form shown in Figs. 6 and 7, the conductor 2 is a helix of copper strap around which is shrunk a ring 3 separated by insulation 7, the whole being mounted on the iron cylinder 1. Fig. 8 shows the application to a homopolar machine for exciting an alternating-current generator 20, the voltage to be maintained notwithstanding changes in the load. The armature consists of a solid steel cylinder 1, and through the centre of the shaft 19 is a copper bolt 17 lightly insulated. A ring 16 is also insulated from the shaft but connected to the bolt 17, and on it rub brushes 15. The field magnet 10 is excited by a coil 23, and the brushes 15 are connected by conductors 13 with brushes 12 rubbing on a ring 11 on the core 1. When the armature rotates, a current flows from 1 to 11, 12, 13, 15, 16, 17, field coil 18, and shaft 19 back to the cylinder 1. The magnetization is varied in accordance with the load by means of the coils 2, 3, similar to those of Figs. 6 and 7, which are excited from the series transformer 22. To regulate in accordance with the power factor, the brushes 4, 5 are rocked so that on unity power factor the magnetizing effect is below its maximum, so that, as the current lags, the magnetization is increased. For a polyphase machine, several primaries may be employed to produce the current in the coil 22.

Title: Improvements in or relating to Mechanism for Operating Brakes and for similar purposes.
Inventor: ROCHE DAVID
Filed: 1905-05-29
Granted: 1905-11-02
Abstract: 11,238. Roche, D. May 29. Brakes.-Relates to mechanism for applying, holding on, and releasing railway-wagon brakes, applicable also to other purposes. The usual hand-levers J are mounted loosely on the usual transverse shaft F, and are connected together by transverse bars G, G<1>. Arms F<1> on the shaft F are engaged by the bar G when the brakes are applied. The brakes are held on by one of several pawls B of different lengths engaging a ratchet segment A, fixed to the shaft F, and shown partly broken away. The pawls are mounted in a frame B<2> pivoted at b to a fixed bracket E'. In the ' brakes-applied' position shown, the pawls are free to engage the ratchet segment, and the frame B<2> is prevented from turning on its pivot by a cam C engaging its end B<4> To release the brakes, the cam C is turned into a position in which a slot C' in the cam comes over the end B<4> of the frame B<2>, which can then turn until the tail ends B<3> of the pawls B are engaged by a stud E on the bracket E<1>. The pawls are thus released, and a spring A<2> or a weight takes the brakes off. The cam C is turned by a pinion engaging a toothed segment D, which is mounted loosely on a shaft F and is formed with an arm D<1> to engage the bar G<1> carried by the levers J. The levers J are held up by lever catches K connected by a transverse shaft K<1>. The catches K may be released, to apply the brakes, by raising an arm N in the permanent way into the path of a lever M<1> depending from the vehicle. The lever M' on striking the arm N lifts a lever L and thereby* turns the shaft K<1> connected to the catches K. The arm N is actuated by a lever N<2> and is held in the raised position by a catch O.

Title: Improvements in Apparatus for Regulating the Admission of Air to the Furnaces of Steam Boilers and for the Better Consumption of Smoke therein.
Inventor: BUTTERWORTH SAMUEL
Filed: 1905-07-21
Granted: 1906-07-21
Abstract: 15,010. Butterworth, S. July 21. Means for absorbing mechanical shocks.-Relates to door-controlled dampers particularly applicable to steam-boiler furnaces having fire-bars arranged as described in Specification No. 25,426, A.D. 1896, [Abridgment Class Furnaces &c.]. Behind the bridge b of the furnace, a chamber a is formed as described in Specification No. 17,771, A.D. 1902, [Abridgment Class Furnaces &c.), and provided with a weighted, hinged, or sliding door d, so that air may pass to the flue and assist in consuming smoke. A cylinder f, containing oil, is fitted with a piston f<1> having a disk or flap valve g, and the piston-rod g<1> is coupled to a cross-head h which in turn is coupled by rods to a lower cross-head h<1>. This cross-head is connected to the air door d by links and levers, one of which j is placed beneath the hinged pin j<1> of the furnace door k and carries a pivoted catch k<1>. As the furnace door closes, a catch, pivoted thereto, operates the catch k<1> and causes the door d to be opened and the piston f to be raised so that oil passes through passages m to the lower side of the piston. The lever j, through the links and levers i, pulls a lever i<1> beneath the outer end of the catch k<1>, thus, with the aid of the spring l<2>, effecting the disengagement of the catches immediately the furnace door is closed. The weight of the air door causes it to close gradually, and operates the links and levers so that the oil is forced through a regulating-valve n to the upper side of the piston. A spring may be fitted between the bottom of the oil cylinder and the lower cresshead, and, instead of employing a liquid, air may be used in the cylinder and the latter may be arranged horizontally. [Reference has been directed under Patents Act, 1902, to Specification No. 15,996, A D. 1900, [Abridgment Class Furnaces &c.].

Granted: 1906-06-21
Abstract: 26,601. Imray, O., [Hoffe, J. A.]. Dec. 20. Cut-outs; switches.-An arm adapted to complete a circuit between two contacts is normally supported by the armature of an electro-magnet, but is released when an excessive current passes. In the construction shown in Fig. 1, a coil a is connected in series with the springs b, b<1>, and is provided with an armature d, pivoted on the pole f. The arm c is pivoted at c', and is supported by a catch d' on the armature while it connects the two springs b, b<1>. A spring g on an adjustable stop h keeps the catch d' in engagement with the arm a. When an excessive current flows, the armature d is attracted, and the arm c drops, thus breaking the circuit and exposing the surface of an indicator i. 'An insulating-stop e may be used to prevent the springs b, b<1> from closing on each other. In a modification, shown in Figs. 2 and 3, the coil a is supported in spring clips j and the spring confacts are normally connected through the metallic indicator i. After operation, the device may be reset by sharply tapping the end m<1> of a short bent lever, the other end m<2> of which jerks the indicator i back to its normal position. The apparatus is particularly applicable for use with the condenser or phonopore coil of a telephone working over an ordinary telegraph circuit, or as a protector against lightning, and may be connected in series with a lightning-arrester.
