Definitions

  • My present invention relates to improvements when performing any switching operations, second to make provision for superimposing two switching operations (such as e. g., cutting in a motor and switching from first to second speed) so as to permit of performing same by a single hand lever, and third to afford means which permit of adjusting any speed or operative switching position alternatively after passing through the intermediate speeds appurtenant to the intermediate positions or, by omitting same, directly from neutral.
  • two switching operations such as e. g., cutting in a motor and switching from first to second speed
  • Fig. 1 is a wiring diagram of the switch and appurtenant devices
  • Fig. 2 shows the operative interpositions which may be effected by the switch lever.
  • the cams 2 for the selector contacts I as well as the special cam l actuating the auxiliary contant I, are secured to the hollow square shaft I.
  • the latter is actuated by the joy-stick 6 swinging in the plane of Fig. 2 at right angles thereto, and is journaled in the bearing 11.
  • the joy-stick 8 is also mounted rockable on the pivot I! in the guide It secured to the shaft I.
  • the coil ll of the circuit-breaker is connected across the holding contact I! in series with the auxiliary contacts in and 5, and the cut-in auxiliary contact 9 is connected in parallel with the holding contact l3. Contacts 9 and III are biased to closed position.
  • the circuit-breaker I2 When the lever B is in the position 0 of Fig/2, the circuit-breaker I2 is broken. When swinging the lever B into any of the positions V1, V2 (forward) and R1, R2 (rearward), is is held by the dented disk 20.
  • the auxiliary cam l is so adapted as to'open the auxiliary contact 5 v hen the lever B in Fig. 2 is in the position 0 or in positions intermediate of V1 and V: or R1 and R2, and to close same in these latter or switching positions.
  • the lever B When starting the motor It, the lever B is first swung into the desired position of Fig. 2, and then rocked into engagement (position E of Fig. l) axially with the rod 1. During the swinging movement the switch l2 remains broken, and only closes when the lever 6 is rocked into the position E of Fig. 1. The lever 6 also, however, may be rocked into the latter position while swinging, whereby the switch 12 is cut in. In swinging the lever according to Fig. 2, the switch l2, in this latter case, is momentarily interrupted due to the breaking of the contact 5. When switchin the motor it off, the lever 6 is rocked or pulled forward (Fig. 1), thereby breaking the contact l0 and interrupting the control current of the switch l2. When swinging the lever 6 according to Fig. 2, without simultaneously rocking or pushing it back (Fig. 1), the switch 12 is opened in the neutral or intermediate positions thereof.
  • , 22 are provided for.
  • the holding circuit of the switch I2 is interrupted. thereby dropping off the latter and keeping it open.
  • the switch I2 is excited and remains closed.
  • any speed or, respectively, switching position may be alternatively set either after having passed the intermediate speeds appurtenant to the intermediate positions or, by omitting same, directly from neutral.
  • a hand operated cam switch for machine tools or the like comprising a switch housing, a hollow shaft rotatably journaled in said housin ing and engaging said loose rod, a coil-tripped circuit-breaker series connected with said selector contacts, a pair of contactors actuated by said spring loaded lever, said last named contactors being so connected to said single contactor and said circuit breaker, that said circuit breaker will be disconnected from said selector contactors and said single contactor when said contactors are rocked by said lever through actuating said loose rod, and said auxiliary cam being so shaped that when said selector cams and selector contacts are not in contact at a determined position of aforesaid lever said single contact and said circuit breaker will be temporarily disconnected, whereby selective current and noncurrent switchings of a motor drive for said tool ay be made.
  • a hand lever engaging said hollow shaft when being swung in one plane and engaging said loose rod when rocked in one direction in a plane at right angles tothe former plane, and wherein said loose rod follows the rocking of said lever in the opposite direction under the action of said springloaded lever, the said lever being rocked to neutra'l whenever let loose.
