Definitions

  • tion is retarded at the ends of the swinging stroke with constant speed for the driving shaft, whereas the turning motion has its maximum speed when the arm is in contact with its counter contact.
  • Figs. 1 and 2 are views-partly in section-looking at right angles to each other, showing one form of the invention intended for the operation of the disconnecting switch arm of electric circuit breakers, Fig. 2 being a sectional view along the line 22 in Fig. 1, and Figs. 3a, 3b and 3c are detail views showing a portion of the mechanism in three difierent positions.
  • the operating shaft I is journalled in a bearing 2.
  • the shaft I carries a bow member 3, which is provided with a circular peripheral slot 4, accommodating rolls 6 mounted on pivots 5, which are attached to a member 'I, mounted on transmission pivots I B (Fig. 2) having an axis extendin through the meeting point 0 of the axes of the disconnecting switch arm 8 and of the operating shaft I.
  • the disconnecting switch arm 8 is pivoted at one end by means of pivots 9 to a socket III, freely turnable about a stud II attached to the said bow memher 3.
  • the disconnecting switch arm 3 traverses an opening or journal I2 in the member I and is, in this opening, so journalled or guided that it can turn around its own axis.
  • I3 designates the stationary contact, with which the contact in the outer end or" the disconnecting switch arm 8 engages.
  • Fig. 1 is in this detail figure represented by the dash-dotted lines.
  • Fig. 3a the stud II has the position shown in Fig. 1.
  • Fig. 3b the stud II and the pivots 9 are shown after a 90 turning of shaft I, and in Fig. 30 after a 180 turning of the shaft.
  • the arm 8 is swung through 90, but is turned through 45 about its own axis, and back again.
  • the pivots, projecting into the slot may be replaced by a ring freely sliding in the slot, and which ring is connected by pivots projecting into it and attached to the swinging member.
  • Mechanism for actuating a disconnecting switch comprising a swinging and rotating con tact arm, an operating shaft arranged with its axis intersected by the swinging and rotating axes of said arm, a member secured to said shaft, a second member pivoted to swing about a fixed axis intersecting the axes of the shaft and arm at a common point, means connecting the said member with the said second member so as to permit relative rotary movement, a universal joint connecting the second member with one end of said arm and having its center of rotation coinciding with said common point, and a journal carried by the second member in spaced relation to said common point and serving to impart the swinging movement to the arm while permitting said arm to turn about its own axis.
  • Mechanism for actuating the contact arm of a disconnecting switch comprising a shaft forming an angle with the contact arm, and having its axis intersecting the axis of said arm, a member carried on the end of said shaft, a second member in sliding engagement with said first member along a circle in a plane disposed at an angle to said shaft, said second member being pivoted along an axis passing through the point of intersection of the axes of said shaft and said arm, a stud mounted on said first member and extending perpendicularly to said plane, a pivot connection between one end of said arm and said stud, with a pivotal axis coinciding with the axis of said second member, said pivotal connection being rotatably mounted in relation to the axis of said stud, and a journal in said member for said arm.
  • Mechanism for actuating the control arm of a disconnecting switch comprising a shaft forming an angle with and intersecting the axis of said am, a member carried on the end of said shaft, a circular race forming part of said member, and arranged in a plane forming an acute angle with said shaft, a second member slidably engaging said race, pivots for said second member having an axis extending through the point of intersection of the axes of said arm and said shaft, a stud carried on said first member and arranged perpendicularly to said circular race, a sleeve rotatably mounted on said stud, a pivot on said sleeve with an axis coinciding with the axis of the second member, a journal in said second memher for said arm, and a fork-shaped part on said arm engaging said pivot.
