Claims2
A device for remote, precise rotary adjustment, comprising in combination a rotary adjustment knob, an annular toothed member fitted over and attached to said knob, an annular plate adjacent said toothed member and movable with respect thereto and a handle member pivotally connected to said plate and having a toothed end engagable with a notch in said annular toothed member;
- said device being characterized in that when said toothed end is engaged with a notch, movement of the handle in one direction moves said toothed member in the same direction;
- said handle being pivotable so as to be engageable with a notch on the opposite side to permit motion in the opposite direction by actuation of the handle.
A remotely actuatable device for controlling a rotary knob (20) or the like, comprising:
- a. an annular toothed member (17) having notches (18a) and adapted to be fitted over and attached to such a knob (20);
- b. an annular plate (11) adjacent said toothed member (17) and movable with respect thereto;
- c. a loop (12) rotatably positioned on said plate;
- d. a handle member (14) having a toothed end (15) and a transverse slot (16) positioned so that said loop extends into said slot;
- and
- e. a pin (13) extending across said slot (16) through said loop (12) so as to form a pivotal connection between said handle (14) and said plate (11);
- said device being characterized in that said handle toothed end (15) is engagable with a notch (18a) so that when said handle is moved in one direction said toothed member is moved in the same direction;
- said handle being pivotable so as to be engagable with a notch (18a) on the opposite side of said loop as to permit motion in the opposite direction by actuation of the handle.
