Definitions

  • the present invention is applied to a switch of the character having a selector member movable into a selected one of a plurality of evenly spaced switching positions, and provides two like-numbered sets of permanent magnets one of which sets is stationary and the other of which moves in concert with the selector member and so related, one set to the other set of magnets, that the fields of the two sets exert one upon the other either an optimum attraction or an optimum repulsion when the selector member of the switch is centered in any one of its several switching positions.
  • FIG. 1 is a view partly in elevation and partly in longitudinal vertical section illustrating a rotary switch constructed in accordance with preferred teachings of the invention
  • FIG. 2 is a front elevational view with a portion of a cover plate for the switch case broken away to expose positioner mechanism housed in a front compartment of the case;
  • FIG. 3 is a view similar to FIG. 2 portraying a modification.
  • a case for the switch is denoted by the numeral 10, being cylindrical in shape with an internal flange 11 dividing the case into front and back compartments 12 and 13.
  • the compartments are shielded from one another by a centrally apertured plate 14 which is secured to the flange, and have the outer ends closed by a respective centrally aperatured cover plates, as 16 and 17.
  • Ball-bearing assemblies 18 and 19 are received in the central apertures of the cover plates to provide a rotary journal for a through-spindle 20.
  • Set screws 21 fix the spindle to the inner races of the bearings to hold the spin- United States Patent O ice dle against endwise displacement.
  • a selector knob 22, with a pointer 23, is secured to an exposed end of the spindle.
  • the spindle has a radial selector arm 24 and a positioner disc 25 fixed thereto, the former for rotation with the spindle within the compartment 13 and the latter for rotation with the spindle within the compartment 12.
  • These two compartments function, respectively, as a switch compartment and a positioner compartment and will be hereinafter so termed.
  • the switching mechanisms 26 are housed in the switch compartment and in the particular embodiment which I have here elected to illustrate are shown as being the dry reed type, with a plurality, say four, of such reed switches being supported by conductive clips 27 to lie in a side-'by-side series at each of several switching stations.
  • the stations, five are here shown, are located at five of six equally spaced positions about the circumference of a circle having the axis of the spindle as its center.
  • a permanent magnet 28 which is or may be of the rubber type is screwed or otherwise secured upon the end of the switch arm, acting by magnetic attraction as the arm moves to a centered postion at a selected one of said stations to close the reed switches.
  • the reed switches are contained in normally incomplete electric circuits each functional to an electric device.
  • I have illustrated four reed switches at each of the switch stations, an arrangement which would pemit up to four separate circuits to be simultaneously closed.
  • Such an arrangement would be suitable for use in a profile mill like or similar to that which I illustrate and describe in my pending application Ser. No. 545,957, filed Apr. 28, 1966, wherein devices conveying logs along a guided travel path and chipping the same in course of such travel are each caused to selectively occupy one of several predetermined positions which are correlated to different log diameters.
  • the magnets in each set correspond as to number with the number of switching stations.
  • the set of magnets 30 is secured to the perimeter of the positioner disc so as to rotate therewith, being placed at equidistant intervals of the circumference of a circle having the axis of the spindle 20 as its center.
  • the magnets 31 of the other set are held stationary, being secured to the surrounding wall of the compartment in closely spaced relation to the movable magnets at equidistant intervals of a circle concentric to the circle occupied by the movable magnets.
  • a switch comprising a case having a spindle journaled for rotation therein,
  • a selector member coupled to said spindle for rotation therewith having a magnet for actuating reed switches mounted on said case at switching stations,
  • a positioner member coupled to said spindle for rotation therewith having a plurality of first permanent magnets equidistantly mounted about the periphery of said positioner member, said first magnets orientated to expose a single pole to said case with the polarity of said first magnet exposed poles being the same, and
  • a selector member coupled to said spindle for rotation therewith having a magnet for actuating reed switches mounted on said case at-switching stations,
