Title: Improved Construction of Asynchronous Motor for Single or Polyphase Alternating Electrical Currents in Combination with an Auxiliary Synchronous Motor.
Filed: 1897-03-02
Granted: 1897-12-24
Abstract: 5569. Abel, C. D., [Soc. Anonyme pour la Transmission de la Force par l'ElectricitÚ]. March 2. Motors, alternating - current.- An asynchronous motor, for utilizing monophase or polyphase alternating currents, is combined with an auxiliary synchronous motor. T h e stationary induced part S of the asynchronous motor M is wound with a number of coils C', C<2>, C<3>, C<4>, which are closed respectively upon a corresponding number of coils C<5>, C<6>, C<7>, C<8> on the stationary armature A of the synchronous motor N. The revolving inducing part I of the asynchronous motor is wound with coils B', B<2> so as to produce two opposite poles, and these coils are connected with the working circuit through contact-rings b<1>, b<2> and brushes f<1>, f <2>. The inducer or field magnet J of the synchronous motor is furnished with a winding D, capable of being connected with a continuouscurrent supply, and carries an annular conducting-screen E which opposes any variation of magnetic flux. When the inducing circuit of the asynchronous motor is supplied with alternating currents, it acts first as a transformer, and supplies the armature of the synchronous motor with currents which cause it to start and run up to a speed very near synchronism. On supplying the inducer of the synchronous motor with a continuous current, the asynchronous motor will be automatically started. Resistances are inserted between the two motors at starting and are afterwards cut out. When monophase currents are supplied to the asynchronous motor, the synchronous motor must be started either by hand or by providing it with two starting circuits, one containing a self-induction coil or condenser and the other a resistance.

Granted: 1899-03-08
Abstract: 5605. Crompton, R., and Wyman, H. March 8. Loom shuttle-changing mechanism.-The shuttle which has failed is automatically displaced or discharged from the shuttle box on the lay, and a full shuttle is taken from the receptacle D and put in place on the lay by an auxiliary shuttle box e, which is carried by a normally stationary rod D<6> capable of sliding in guides D<4>, D<5> in a stand D<3> loosely mounted on the shaft D<2>. When the weft fails, the weft-fork slide is operated by the hammer C<2>, and by means of levers B<8>, B<10> releases the device d<x> which holds the rod D<6>. The spring d<6> acting upon the arm d<7> is then allowed to move the auxiliary shuttle box against the lav and underneath the shuttle box on it. The former shuttle box is then raised to take the place of the other at the level of the shuttle race by means of levers e<2>, e<3>, e<5>, operated by a crank disc on the shaft e<8>, which is rotated at the required times by mutilated gearing f, G from the cam shaft B<2> under the control of levers e<12>, f<6> actuated by fingers g, g<x> on the box rod U‹. The other shuttle box is lifted between the guides A<4> , and its shuttle is thrown upon a receiver m. A plate h<2> at the back of the shuttle box e is mounted upon a shaft h<1> and is held in position by an arm h<3> connected to a leg h<5>, which in the raised position of the shuttle box rests upon a step h<9>. After the shuttle has been picked from this box the other box is allowed to descend again, and the auxiliary box is withdrawn to its normal position. During this movement the step h<9> acting upon the leg h<5> causes the plate h<2> to be moved backwards to the position shown in dotted lines, in order to take another shuttle from the receptacle D. Finally the holder d<x> again retains the auxiliary box in its stationary position, and the step is removed from the leg by the movement of the lay.
