ELECTRIC CIRCUIT CONTROLLER.
APPLICATION FILED SEPT. 24, 1907.
l/vilmcaaca M a from current flowing through the circuit, and
winding to the line, whereupon the speed of the motor will increase; to further increase the speed of the n otorrod 2 is pushed further into casing 1 whereupon the circuit will be from line 8, spring 7, rod 2, contacts 11 and 14, and conductor 21 to the motor wind-- ing, cutting outt-he resistance, and thence to the line, whereupon the motor will operate at high speed. The speed of-the motor may be varied as desired by pressing in rod 2 0r allowing the same to be pushed out-by spring 7 to bring either pair of contacts into engagement as desired. Thus, with a sewing ma chine eqdipped with-my improvements the same may be operated by merely operating rod 2 by .the footas desired for throwing in more or less resistance to the circuit. Byhaving the contacts 9 to 14 inelosed within casing 1, the operator is protected sparks from the make and break at. tliecon tacts are confined within the casing.
Having now described my invention what lcliiimis: p i H 1. The combination of a casing, a rod mounted to slide therein, and provided with contacts in circuit therewith andspaced apart", contacts to co-act witl1 -t-he first nain ed contactsand s aced apart, and a spring to move said 'ror upwardly, QLfldUCbOIiS connected with the second named contacts," translating devices connected with said "conk. duet-ors, and a conductor in circuit-with said devices and with said rod.
2. The combination of a casing, a rod mounted to slide tl'iercin and provided, with; contacts spaced apart, contacts to. co-act with the first named contacts and spaced apart, a spring to move said rod upwardly, and nc-ans to prevent rotation of said rod, conductors connected with the second named contacts, translating devices connected-with said conductor ainl a conductor in ir ui with said devices and with the first named contacts,
3. The combination of a casing, a rodl guided to slide therein and provided with a plurality of contacts spaced apart, a plurality of contacts within said casing, a resistance, and a motor, one of saidcont'acts being connected with one terminal of the resistance,'another of said contacts being connected with an intermediate part of said resistance, and another of said contacts being connectedwith'the motor around said resistance, saidfresistance also being connected withthe niotor.
4. The 'i'combination of a casing, a rod guided to slide therein and provided with a )lurality of contacts spaced apart, a plurality of contacts within said casing, a resistance, and a'motor, one of said contact-s being connected with one terminal of theresistance, another 0. mid contacts being connected with an intermediate partof said'resist- :ance,'and anoth'e'riof said contacts being connected with the motor around said resistance,
said resistanceal so being connected with the -motor, a sprin infcircuit with the rod to move i outwar ly, and a line wire connected with said sprin I 'SQiThe coin ination'of a casing, a rod guided to slide therein and rovided witha -foot piece insulated there rom", a spring c'oile'd around said rod and in contact t ierewith, said rod having a plurality of contacts spaed apart, cont-acts withinsaid casing "s aced apart,"a motorand a-resistance, one
0 said contacts being connected with a terminal of said resistance, another of said contacts being connected with an intermediate part of said resistance, another of said con-- tacts beingconnected with a motor around said resistance, and a line wire connec ed with said spring. g
