Granted: 1901-08-24
Abstract: 16,052. British Thomson-Houston Co., [Steinmetz, C. P.]. Sept. 10. Distributing; transformers converting alternating and direct currents.-Relates to alternating current distribution, and essentially to the transforming of currents of one phase into currents of another phase or value. Magnetic fluxes are produced and combined, and the resultant flux employed to produce electromotive force. The invention is particularly applicable for regulating dynamo-electric machines on the principle described in Specification No. 29,585, A.D. 1897, in which alternating current is supplied to the armature of the separate exciter. Fig. 1 shows the application of the invention for regulating a two-phase generator G, and incidentally the construction of a transformer T and of an exciter E. The transformer T has three limbs square in section, and has windings e, b, a, f so proportioned, Fig. 2, as to produce a resultant flux which induces three-phase electromotive forces in windings s', s<2>, s<3>. Three windings are connected to the armature of the exciter E. For producing stability in an exciter having a weak field and high armature reaction, each field pole N has an auxiliary air gap formed by a deep cut or slit.

Granted: 1902-11-06
Abstract: 22,656. Baker, G. S. Nov. 9. Conveyers.-Consists of conveyer apparatus especially adapted for passing articles through a cooling, drying, heating, or like chamber without exposing the interior of the chamber to the external atmosphere. The chamber has a charging- mouth A<1> and a discharging-mouth A<2>, preferably one above the other, and the articles are contained in receptacles which fit these mouths. The receptacles are connected together and run on rails B', B', in line with the mouths. At the end of the rails within the chamber is an elevator apparatus, on to which the last receptacle of the upper train runs and is then lowered into line with the lower train on the rails B'. An elevator appatraus in front of the mouths of the chamber returns the receptacles as they are discharged into line with the upper rails, so that a continuous circulation may take place. The front elevator, one side of which is shown in transverse section in Fig. 4, comprises two pairs of lifting-springs H, and a pair of rail sections J supported on springs J<1> so that the rails J are pushed aside as the receptable rises, and then drop into place under it. The rear elevator consists of a rising and falling pair of rails, and, in a modification, the front elevator is similar. The receptacles in each train are coupled together by vertical bellmounted grooves and tongues, so that, when raised or lowered as described above, they are at the same time coupled or uncoupled. The upper and lower trains are moved alternately by reciprocatiog spring pawls. These pawls, and also the elevators, are moved in proper sequence by means of toothed quadrants F<1> carried on a rotary shaft F and engaging toothed wheels F<3>, L<6> with locking-portions F<5>, L<7>. The wheel F<3>, by means of the linkage shown, operates the elevators, and the wheel L<6> the pawls which move the receptacles into and out of the chambers. The cooling &c. fluid may be circulated in the chamber by pipes N, having gutters under them to convey away any condensed moisture to a discharge gutter N<3> and outlet N'. Various modifications are admissible. The receptacles, for instance, need not fill the mouths of the chamber, but may carry ribs or plates for that purpose. Or the coupling-tongues may be omitted, and the receptacles advanced and withdrawn by pushing.

Title: Improvements in and relating to Looms for Weaving Two Fabrics simultaneously, or for Weaving Figured Fabrics.
Inventor: BAUDRE GASTON
Filed: 1903-04-11
Granted: 1904-04-11
Abstract: 8370. BaudrÚ, G. April 11. Looms for weaving two fabrics in parallel planes, and double fabrics with the figured design and the foundation woven simultaneously. Jacquards.- Two sheds are formed, and, when jacquard mechanism is used, the hooks are made of two lengths. The shorter hooks are first engaged by the lifting-blades, and then the longer hooks, so that the shorter hooks are raised through the greater distance, and their warps form the upper shed. The warps, which come from one or two beams, are, normally, all in one plane. Shuttle boxes; pickers; shuttle - races.-Two shuttles are used, and are simultaneously propelled by a single elongated picker. The upper shuttle box 2 is supported above the lower by a bracket 1. The upper shuttle-race consists of a grid 6, with bevelled dents, mounted on supports 4, which are pivoted to the lay at 9, and held in place by a spring 7 abutting against a fixed part 8. In case of accident, the grid may be raised by being rotated round the pivot 9. The dents of the grid 6 come near the dents of the reed. Reflector arrangements.-In the space between the upper shuttle box and the grid 6, a mirror is placed, so that the lower fabric may be watched. Stop-motions.-If either shuttle fails to enter its box, one of two sliding abutments 13 fails to act on a swivelling piece 12, a lever 14 is not tilted, and the loom is stopped in the usual manner. Forming selvages.-A stout cotton thread is passed through the reed beside the last selvage thread, and the weft passes over and under it. The selvage is thus accentuated or made more distinct.
Patent GB-190309805-A (GB)
Title: Improvements in Emergency Brakes for Railway and Tramway Vehicles or Trains
Inventor: CAROLAN EDGAR ALFRED
Filed: 1903-04-30
Granted: 1904-03-24
Abstract: 9805. Carolan, E. A., [General Electric Co.]. April 30. Electric motor vehicles.-Relates to improvements in the emergency brake-controlling devices for railway and tramway vehicles described in Specification No. 19,562, A.D. 1902, and provides means for controlling the motors and for causing the brake to be applied when the controller-operating handle is released by the motorman in any position, including the off position, so that, if the man becomes incapacitated, the brake will be applied when he releases the handle ; it also provides means for releasing the brake, and for locking the brake-controlling means in such a position that the handle may be released without causing the application of the brakes. The invention is specially intended for use with fluid-pressure brakes in an automatic air-brake system, in which the emergency valve exhausts the train-pipe to the atmosphere, the valve P is connected by a pipe 13 to the train-pipe, and, in applying the brakes, exhausts this pipe through a port 14. If the apparatus is in the position shown in Fig. 2, when the motorman places his hand upon the handle, the pin e<1> is depressed, and a sliding bolt G forced down into a notch in a loose sleeve F locks this sleeve to a shaft D. Rotating the handle, through a cam f on the sleeve and a rocking shaft H, then closes a cut-out switch I, and controls the motor circuits through the controlling-cylinder B. The switch I is formed by an arm on the shaft H carrying a block H, on which are mounted two connected spring contacts co-operating with stationary contacts. So long as the knob is depressed, in any position of the controller, a lug o on the underside of the cam f, will be held out of engagement with a lever k, and the emergency valve will remain closed ; but, if a rod 20 be not pushed in to lock the cam, as shown in Fig. 2, as soon as the hand is removed from the knob, the sleeve is released and will be turned by a spring F<1>, so that the lug strikes the lever k before a lug f<1> contacts with a stop a' on the cap-plate. The emergency valve is thereby operated to apply the brakes, and, at the same time, the shaft H opens the motor circuit at the switch I. The mechanism is then in the position shown in Fig. 3, and the brakes cannot be removed by attempting to depress the knob, since the bolt G cannot enter the sleeve F. To remove the brakes, a rod 14<1> is used to rotate the cam, so that the lug o is disengaged from the lever k and the lug f moved away from the stop a'. The bolt G can then enter the sleeve and render the valve inoperative. If the man wishes to leave the car, he may lock the mechanism by pushing in the rod 20.

Title: Improvements in Automatic Stopping Devices for Power Looms
Inventor: KOZIAN JOSEF
Filed: 1903-05-27
Granted: 1903-09-17
Abstract: 12,079. Kozian, J. May 27. Loom stop - motions.-The object is to stop the loom after a certain length of fabric or a particular part of the pattern has been woven. A chain 20 driven from the sand roller 22 is provided with catches or stops 21, which, at the proper time, lift a forked lever 12. The lever 12 is adjustably carried by a cam-disc 13 near the lower end of a spring lever 4, the upper end of which carries a hammer 6, ard the lower a spring hook 17, which is normally held out of engagement with the projection 16 on the lay 15 by a nose on the cam-disc 13. When the lever 12 is raised by the catch 21, the spring hook 17 is released and brought into the path of the projection 16 so that, on the next beatup of the lay, the lever 4 is turned, and the hammer 6 releases the stop-rod 26. The lever 12 may be connected by a lifting-wire 33 with the dobby or jacquard of the loom.
