Title: Improvements in Track Brakes for Electric Tram Cars and the like.
Filed: 1906-11-13
Granted: 1907-11-07
Abstract: 25,557. Mountain & Gibson, and Head, A. F. H. Nov. 13. Brakes. - In a track brake for electric tramcars &c., the bulk of the stress comes upon the side frames of the undertruck, and wear of the brake shoes is automatically compensated for. The shoes b and holders a at the two sides of the vehicle are connected by cross-bars d, and are suspended by an adjustable link e<3> from an arm f on a cross-shaft g. The shoe is held in the elevated position shown by springs l, which are connected to a bar n on the holder a and are suspende from bell-crank levers k<1>, k<2> mounted in brackets j on the truck frame i. The shoes are pressed on to the track by pulling on one of the rods p<1>, p<2> connected to a lever o on the cross-shaft g. The frictional drag between the shoe and the rail causes the serrated edge of the bracket e<1> or e' on the holder a to engage the toothed end of the lever k<1> or k<2> respectively, and as the lever turns it presses the shoe harder on to the track. The movement of the levers k<1>, k<2> is limited by stops m, q. To compensate for wear, a lever r, mounted loosely on the shaft g, carries an excentric z which engages a disk w fast on the shaft. When the disk w is turned in applying the brake, a spring t moves the lever r over until the excentric meets a stop s<1>. If the shoe is worn, the shaft g can continue to turn until the shoe meets the rail, so that, when the brake is released, the excentric z is engaged by a different point of the disk w, and as the backward rotation of the shaft is stopped when the disk has carried the excentric into contact with a stop s<2>, the wearing surface of the shoe is maintained at a constant height from the rail. The disk w and excentric z may be replaced by a ratchet-wheel and pawl. Springs acting upon the rods p<1>, p<2> tend, in conjunction with the spring t, to apply the brakes, but their combined strength is less than that of the releasing- springs l.

Title: Improvements in Variable Speed Pulleys and Gearing.
Inventor: HAIGH CHARLTON
Filed: 1907-07-03
Granted: 1908-07-03
Abstract: 15,276. Haigh, C. July 3. Driving-mechanism; motor-cycles.-In a variablespeed gear for motor-cycles &c. two disks c, d with internal conical faces are mounted on the boss b fixed to the driving shaft and are adapted to slide on feathers e. Balls h are mounted in ball races, consisting of hardened steel rings placed in grooves in the disks c, d, and partly rotatable rings g. These second rings are each provided with a radial arm i, the two being connected by a pin j to which is attached a rod k coupled with an operating- handle on the machine frame. The outer faces of the rings g are provided with inclined planes m, corresponding surfaces n being formed on stationary brackets n<1> attached to the casing directly or through distance-pieces p. By partly rotating the rings g, through a rod k, the disks c, d may be simultaneously moved. Ball races q may be used on one or both sides of the pulley to take up the strain between the boss b and ring g. To prevent the displacement of the balls h, to the rings g are fixed arms r or a metal tube with projecting screws or ends s, engaging an annular recess or a flange on the disks c, d. When two pulleys are used together the belt may be kept at the same tension by causing suitable levers to operate the cams in unison. A jockey pulley may be used for the same purpose by mounting its shaft in slots in additional arms affixed to the cam rings. The shaft is also adapted to slide in suitably shaped grooves in the machine casing, so moving the pulley to tension the belt.
Patent GB-190718881-A (GB)
Title: Improvements in and relating to Dynamo Electric Machines.
Filed: 1907-08-21
Granted: 1908-06-25
Abstract: 18,881. British Thomson-Houston Co., and Dawson, W. F. Aug. 21. Motors, controlling; brush holders.-Relates to the short-circuiting devices used in dynamo-electric machines and more especially in induction motors of the type having wound rotors, and consists in mechanism for removing the brushes from and returning them to the slip-rings interlocked with other mechanism for independently short-circuiting the rings, so that it is impossible to move the brushes when the short-circuiting device is inoperative. The collector - rings and brush - carrying mechanism are enclosed in a hinged casing b surrounding the end of the rotor shaft. A rod c is mounted parallel to the shaft in bearings in the casing and secured at one end to a lever d outside the casing. The other end of the lever d has a spring-pressed pin f at its end, by means of which the rod c may be moved from end to end of an arc-shaped slot g<11> and locked in position at either extreme end. Rigidly fixed upon the rod c are a number of crank members k through the outer ends of which passes a rod l of insulating-material. To the rod l are connected, through a lost-motion connexion, a number of clips m adapted to be sprung on the brushes n of the machine. When the lever d is turned, the brushes are lifted out of or returned into their holders o in a direction radial to the slip rings. For short-circuiting the rotor windings, the contact member p in the form of a cylinder is adapted to be inserted or withdrawn through a cylindrical aperture in the rotor shaft so as to make or break contact with the slip-rings. In starting the machine, the contact member is withdrawn so as to open the shortcircuit, and when the proper speed is attained it is inserted to its full extent. The contact member is interlocked with the lever d by means of a slot d<1> in the lever, through which the end of the contact lever passes so that it cannot be withdrawn except at the enlarged portion of the slot, that is, only when the brushes are rubbing upon the sliprings. In the same way, the brushes can only be removed when the short-circuit is closed.

Title: Improvements in Balancing the Lines of Electric Circuits particularly those Employed in Duplex Systems of Telegraphy.
Inventor: JUSTICE PHILIP MIDDLETON
Filed: 1907-10-15
Granted: 1908-09-03
Abstract: 22,728. Justice, P. M., [Rowland Telegraphic Co.]. Oct. 15. Testing.-In a method of balancing the artificial and real lines in duplex telegraphy, also applicable for indicating the equality of the time-constants of other electric circuits, the relative effects of the different quantities concerned are indicated separately and the values of the constants are changed until a balance of each is indicated. In the arrangement shown in Fig. 1, the real line L and the artifical line A are connected through the two coils of the differentially-wound relay M to the field coils F of two indicating-instruments of the electro-dynamometer type. The moving coils B, D are connected in parallel across the ends of the real and artificial lines, a resistance rand condenser c being arranged as shown. In balancing the circuits, the artificial line is adjusted until the two pointers p, p<1> rest at zero on their scales. In modified arrangements (1) an inductance replaces the condenser c ; (2) the field-coils are divided into two similar sections, one section being in the line - circuit and the other in the artificial line ; (3) the field-coils are in a separate circuit or branch from the main circuit. In a further modification, a permanent magnet P, Fig. 5, replaces the field coils F, Fig. 1, the coils B, D being then connected in series with a resistance r. With this instrument, the resistance-adjustment is first made until the coil D remains unaffected, and the capacity-adjustment is then made by observing the coil B. In practice the instruments shown in Figs. 1 and 5 would be combined and provided with a switch so that the resistance-adjustment and a fair capacity-adjustment would be made with the instrument shown in Fig. 5, and then a more accurate capacitybalance obtained by the instruments shown in Fig. 1. When alternating-currents with reversed half-waves are used for telegraphing, the coil B, Fig. 5, indicates the balance for the alternating-currents and the coil D for the kicks due to the reversed half-waves. In order that the lines may be balanced while signals are being received, the indicating - instruments may be momentarily connected in circuit by a rotating commutator.

Granted: 1908-02-27
Abstract: 22,833. Conrad, F. Nov. 3,1906, [date applied for under Patents Act, 1901]. Armatures; sparking, preventing.-In order to prevent sparking at the commutator, the armature of an alternating-current machine is wound with several coils arranged in each core slot and provided with cross-connectors so that brushes fewer in number thin the number of poles may be used, the cross-connectors being so arranged that they divide the armature winding into groups of coils, each group comprising coils connected to three or more commutator segments. In the arrangement shown, the magnet system is provided with eight poles 1, 2, 3 ... 8 for starting and lowspeed running, switching arrangements being provided to reduce the poles to four for normal running. The armature winding consists of a number of coils 11 one or more of which may be placed in the same core slots, the winding being in this manner divided into groups of coils 25, 26, 27, &c. ; each coil is connected to a segment of the commutator 12 on which bear two brushes. The terminals of the groups of coils, which are correspondingly situated with regard to like poles and consequently are at equal potential, are connected together by means of cross-conductors 15, 16, 17, &c. In the position shown, the brush 14 short-circuits the coil 29 of the group 25, and the groups 26, 27 and another symmetrical group (not shown) ara connected together, by the cross-connexions, in parallel, and all connected in a closed circuit which includes also the coils 30, 31. The arrangement is shown diagrammatically in Fig. 3. The electromotive force on the three parallel connected groups of coils 26, 27, 28 is for the most part opposed by the electromotive force in the coils 30, 31, and the short-circuit current in the coil 29 is reduced by reason of the impedance offered by the parallel circuits 26, 27, 28 which have the same effect as resistance leads.

Abstract: 25,051. Lock, W. H., [Wood, H. A. W.]. Nov. 12. Printing-apparatus combined with apparatus for printing from engraved plates.-Relates to intaglio printing- plates, and to means whereby intaglio plates may be used in conjunction with relief plates of usual form. In the example shown in Figs. 5 and 6, the intaglio design a<3> on the plate a is surrounded by a surface which contacts with the paper during printing extending outward from the design only as far as the line a<2>, and around this surface is a surface b depressed below the plane of the design, which does not contact with the paper. Between the two surfaces is the usual bevel c to facilitate the passage of the scraping or cleaning device. On the plate a, or on a separate plate at the side, relief characters d may be arranged, either in the same plane as, or slightly lower than, the intaglio design. In the former case, the scraper is cut away or raised to avoid removing the ink from the relief characters. In a modification, each plate has on its surface a design which extends close up to the edge,
