Title: Improvements in and connected with Current Collectors for Electric Vehicles.
Inventor: LAVAGNE LOUIS
Filed: 1902-02-06
Granted: 1903-01-01
Abstract: 3059. Lavagne, L., and Bertrand, L. Feb. 6. Electric railways and tramways with overhead conductors. Collectors.-The trolley wheel B is mounted in the arms C of the fork, of which the swivelling shank E is secured in the bearing by a nut G where its pointed end rests on a screwed block H locked by a nut. A fork consisting of two arms L pivoted on the wheel spindle is normally held upright by springs Q and stops J on the slides I which are dovetailed to the sides of the fork C and are held up springs P. In case of obstruction by cross-wires &c., this slide I is lowered by the cam-shaped ends T of the outer and larger fork or arms M pivoted at N, and both forks can thus pass, afterwards being returned to aid in keeping the trolley wheel on the wire. To set the wheel on the wire in the first instance, use is made of a gaff V with a long spike to act as a guard and a hook to engage the arm U. The trolley wheel runs in a box Y placed in the swivelling fork and filled with oil to lubricate its groove and the wire. Adjustable slides Z close the top of this box and fit close to the rim of the wheel. If obstructions from cross-wires &c. are absent, the guide forks may be fixed.

Title: Improvements in Commutators for Polyphase Currents
Inventor: HEYLAND ALEXANDER
Filed: 1903-01-02
Granted: 1904-01-02
Abstract: 117. Heyland, A. Jan. 2. Commutators;motors, alternating-current.-Relates to arrangements for converting a polyphase current into a current of different frequency or into a direct current or vice versa, alternating- current motors being employed. In Specification No. 11,738, A.D. 1901, an alternating-current motor is described in which the closing-ring of the armature is formed as a commutator and a current is supplied to it by means of brushes. The brushes and commutator sections are so arranged that there will be no complete interruption of current, the commutator sections being connected through a resistance. In the present arrangement, means such as auxiliary circuits are provided for reducing or dispensing with the resistances. Fig. 18 shows the invention applied to a self-exciting machine for converting a polyphase into a direct current. The stator S is supplied with three-phase current from the mains I, II, III, and the rotor with a portion of the current obtained from a transformer T through the brushes b and commutator C. A direct current is taken off from collecting-rings w, w<1> connected to the commutator. In this arrangement, the brushes and commutator are so fitted that the winding is never open, and the resistances are dispensed with, as shown in Fig. 14. The arrangement of brushes and commutator segment is made to suit the different kinds of motors employed. Fig. 3 shows an arrangement in which auxiliary brushes connected by resistances r', r<2>, r' to the main brushes are employed, and the winding is connected to alternate segments. In other cases, the brushes may be divided into three or more sections connected by resistances. It is stated that the object of these connections is not to prevent sparking, but to secure that the winding circuits are never open. With multipolar machines it is not necessary to place brushes on all the segments connected to the windings, it being sufficient to interconnect segments symmetrically placed. Fig. 10 shows such a machine, and, in addition, the auxiliary brushes are shown disconnected from the main brushes but interconnected through resistances r ; with this arrangement of brushes the windings c are either closed by the main brushes or the auxiliary brushes. This arrangement is stated to be advantageously used with the machines described in Specification No. 13,738, A.D. 1901. Fig. 11 shows a commutator for a two-phase winding, or one winding may be entirely omitted, when the transformed current will be a single-phase current of lower periodicity. It is not necessary with synchronous rotation to subdivide the commutator into small segments, but with a proper width of brush the arrangement shown in Fig. 14 may be adopted.

Abstract: 8278. Thomson, J. M., and Thomson, W. T. April 9. Nitro-cellulose.-In the manufacture of nitro-cellulose, the waste acids are removed by direct displacement with water. The nitrating- vessel a is provided with a perforated false bottom b, supported on the base c by means of ribs c<1>, the outlet pipe being provided with a perforated plate e. A charge of nitrating-acids is introduced by the pipe m, the cellulose is then added, and sulphuric acid, or other inert liquid, having a density not greater than that of the waste acids formed, is run on to the surface of liquids from the tank k through the pipes h, h<1> into the perforated troughs f and down the depending aprons g. When the nitration is complete, water is run gently on to the surface through the tubes h, h<1>, and the acid slowly drawn off. The first part of the nitration may be carried out with waste acid from a previous operation, and the apparatus may be used merely for washing purposes, the nitro-cellulose being introduced, covered with waste acid, and treated as described above. The process may be carried out in an ordinary centrifugal nitrating machine, which is used to effect preliminary drying after the acid separation. The acids and water may be supplied to the centrifugal machines or other vessels by perforated pipes lying along the edges of the nitrating-vessels.

Granted: 1903-10-22
Abstract: 16,878. Stiner, C. M. Aug. 1. Telegraphs.-Relates to appliances for receiving and storing the ribbon or tape from printing-telegraph instruments in such a manner that any portion is readily accessible, coils of tangled tape being avoided. Fig. 1 shows the apparatus in plan view, G being the printing-instrument, and H the tape, which is received in grooves s<5> formed in sliding pans s<1> fitted in supporting-trays s. The grooves have overhanging edges s<6> to retain the tape. The trays s are supported on platforms B, C, carried by shafts B', C', which are connected together by gearing b<1>, D, c<1>. At each revolution of a drum K, over which the tape passes on its way to the printing-instrument, the arm M' and shaft M are rocked by the tripper k, and a weight-driven motor J is released for a sufficient time to effect the ope. ration of a shearing-blade P, and to move the tray s forward by means of the pawl n', Fig. 5, so as to bring the next channel s<5> into position to receive the strip. The trays are thus gradually trans. ferred from the pile on the platform B to the pile on the platform C. Each time a tray is moved clear of the pile B, the subdivided weight E<2> lifts the pile, and at the same time drops one of the members e so as to compensate for the removal of the tray. After a time, the weights fare picked up, to compensate for the increasing load on the platform C. Fig. 6 shows how a sliding pan s<1> can be withdrawn from any tray in the pile for inspection.

Title: Improvements in Railway Switching and Signalling Apparatus.
Inventor: NEELEMANS ALFRED
Filed: 1904-05-10
Granted: 1904-08-25
Abstract: 10,778. Neelemans, A. May 10. Controlling and locking signals.-Relates to arrangements in connection with electricallyoperated switches and signals, and comprises improvements in the apparatus described in Specification No. 6546, A.D. 1903. In the Specification referred to, a magnetic cut-out switch is described as operating in the event of a short-circuit in the system to prevent a false movement of a switch or signal. The present Specification describes an arrangement in which the same false movement is avoided although the cut-out switch may be held closed. Fig. 1 shows a circuit-breaker relay, the contacts j, k of which are normally closed, allowing the current to pass through the posts d, b The circuit through the magnets e is of high resistance and is always closed, having no effect while a current passes in the main circuit, but breaking the main circuit when the current ceases. By way of example, a short-circuit is supposed to exist between the wires 14<b>, 14<c>, Fig. 3. Should the operator move the controller so that the brushes 19<c>, 20<c> are in contact with 16<c>, 17<c>, 22<c>, 23<c>, the current flows from the battery 36 through the contact k, switch arm 39, contact 41, fuse 31<c>, magnet 30<c>, brush 19<c>, and the wire 14<c> to the wire 14<b>, and then through the brush 19<b>, magnet 29<b>, releasing - coil 47, and the wire 49 to the battery 36. The releasing-coil 47 neutralizes the retaining-coil 51 and permits the switch 39 to fly open. The current is then shunted through the coils e of the switch k, moving the arm i and breaking the main circuit. If, however, the switch 39 is held closed, nothing is accomplished, since the circuit is broken by the arm i. Closing the battery through any motor in the system will have no effect on the magnets e, and the open condition will be maintained as long as the shortcircuit exists. The same result would occur if the short-circuit existed between an operating-wire, say 6<a>, and an indication wire, say 14<b>.
