Abstract

A device for automatically dispensing a unitary product has a frame having two grooves therethrough. A coil having a movable core is joined to the frame and one end of one U-shaped flange is joined to one end of the core of the coil for movement therewith. A stud is fixed relative to the frame and cooperative with the one U-shaped flange for guiding its movement. A projection from the one end of the one U-shaped flange joined to the core also butts against the stud, whereby to limit the movement of the one U-shaped flange with the core. A rack on the one U-shaped flange and a pinion rotate a toothed wheel at one end of another U-shaped flange. Two fingers are rotatably connected to the other end of the other U-shaped flange for movement respectively along the grooves upon the rotation of the other U-shaped flange for dispensing the product.

Claims

1. An automatic unitary-product dispensing device, comprising:

a frame having two grooves therethrough;

a coil having a movable core, the coil being joined to the frame;

one U-shaped flange joined at one end to one end of the core of the coil for movement therewith;

a stud fixed relative to the frame and cooperative with the one U-shaped flange for guiding the movement thereof with the core;

a projection at the one end of the one U-shaped flange joined to the one end of the core but butting against the stud, whereby to prevent further movement of the one U-shaped flange with the core;

a rack in the one U-shaped flange for movement therewith;

a pinion meshed with the rack for rotation upon the movement of the rack with the one U-shaped flange;

a toothed wheel meshed with the pinion for rotation thereby;

another U-shaped flange secured to the toothed wheel at one end for rotation therewith and extending into two lugs at the opposite end;

rotatable means positioned between the lugs for rotation therebetween;

two fingers connected to the rotatable means for rotation therewith and movement respectively along the grooves upon the rotation of the another U-shaped flange, whereby said fingers engage a product to dispense the product.
