Definitions

  • the present invention relates to an arrangement .for controlling electrically operated apparatus, and aims to provide means whereby a limb of the :human body, for example, a finger, (and hereinafter, for convenience of reference only, referred to. as fingerfi, can control said apparatus in such manner that thexamount of work performed by the apparatus is determined by the pressure of the finger thereon, and the capacity or amount of work performed is perceptible to said finger.
  • a limb of the :human body for example, a finger
  • fingerfi can control said apparatus in such manner that thexamount of work performed by the apparatus is determined by the pressure of the finger thereon, and the capacity or amount of work performed is perceptible to said finger.
  • My invention broadly comprises a finger .operable lever with a servo-energy source and an arrangement of switches, whereby the finger is rendered sensible to the movements and force exerted by the working members of the apparatus.
  • pressure .on the lever is adapted to set in motion a .motor fed. by a source of energy, said motor driving the working parts .of the apparatus, so that the movement and force exerted by these working parts react on the finger-operating the lever and cause its mechanical reaction.
  • said motor may, by suitable means, he set operation and stopped both by the finger and by the reaction exerted by the working parts of the apparatus in carryingout their work, so that the working parts can .be stopped during their movement and be locked automatically in a static loaded position without further expenditure of energy on the part .of the source of energy feeding said motor.
  • the finger operable lever of the apparatus constitutes part (of a closed chain .of mechanical parts arranged betweenlsaid finger and the working parts of the apparatus.
  • Fig. 1 is a diagrammatic, mechanical and electric representation of "the device incorporating a pair of scissors, in a position of rest.

  • said pliers being in a position wherein they exert a certain pressure, without use of electricity.
  • Fig. 4 shows the device during the separating movement of the working parts, i. e., the jaws of the pliers.
  • a lever I pivoted on a pin 2 to a fixed part of the apparatus (not shown and fastened to a table or stand by suitable means) supports at its other end a two way switch 4.
  • a toothed sector 5 is pivoted at 6 at a short distance from a pin 2.
  • Said toothed sector 5 is in engagement with a worm gear I on the shaft 8 of an electromotor 9, the latter being firmly secured to lever I and .fed by a battery It, sector 5 is pin-joined to two levers H and 12, which in turn are operatively connected at H H to the blades of the scissors (or pliers) 13, 54 adjacent thereto and which are pivoted at IE to the fixed part of the device.
  • the outer laminae H and I 8 of the switch 4 are held equidistantly from the middle lamina t9 by means of an insulated distance piece latter is fastened to an end 2
  • the other end 25 of the inner part of the Bowden cable 22 is connected with a cranked lever '26, whose axis of rotation 21 is on the fixed part of the device and whose shorter arm can be moved by the shank 3 of a lever pivoted at 3 and adapted for operation by one finger.
  • the movable lever 3 and an immovable lever 3 form together a scissor-like mechanism movement of which can be effected by the fingers of one hand similarly to a scissors or pliers move ment, and a spring 25 ensures that the shorter arm of the lever 25 is always adjacent to the lever 3 which latter is kept in position by a spring 3
  • a switch 28 having fine laminae, the two inner laminae 3c and 38 being held by an insulated distance piece 32 equidistant from the middle lamina Said distance piece 32 is connected by another Bowden cable idwith the sector 5, and the outer fixed casing of the cable 34 is made fast at '35 andtt to the fixed part of the device.
  • An operating arrangement comprising in combination, an implement to be moved, said implement comprising at least one movably mounted operating member for operating the same; a first pivotally mounted support member connected to said operating member of said implement for moving the same; a second pivotally mounted support member supporting said first pivotally mounted support member; electrically operated drive means mounted on said second support member and engaging said first support member for moving the latter so' as to move said operating member; first switch means mounted on said second support member; a pivotally mounted actuating lever operatively connected to said first switch means for operating the same; second switch means mounted on said actuating lever; an electrical circuit including said first and said second switch means and said drive means so that the latter is controlled by said first and second switch means; and transmission means interconnecting said second switch means and said first support member for transmitting to said actuating lever resistance encountered by said implement during movement thereof, so that the operator will encounter during operation of said actuating lever a resistance varying in dependence upon the resistance encountered by said implement.
  • a support member having a portion thereof mounted for pivotal movement about a given point; a first switch means mounted on said support member on one side of said point and comprising at least two leaf contact members mounted for movement toward and away from each other; an actuating lever mounted for pivotal movement at an intermediate .part'thereof;
