A novel electromechanical apparatus for operating the conventional rolling pin on a motor-driven disc board for making dough discs out of dough balls. The apparatus comprising: a box-like housing structure for the mechanism; a motor-driven disc board on top of the housing structure; a reciprocating rolling pin on top of the rotating disc board; a glider for mounting the rolling pin; a slider-guide mechanism for imparting reciprocatory motion to the glider; a drive link for translating the rotary motion of a motor-driven eccenter into the reciprocatory motion of the slider; a frame structure for supporting the aforesaid drive system; a manually shiftable motor mounting bracket for varying the rolling pin stroke length; a four-bar mechanism for raising and lowering the entire frame structure along with the drive system to effectuate raising, lowering, and pressing of the rolling pin over the dough; two lower brackets, rigidly attached to the housing walls for mounting the four-bar mechanism; a momentary stop switch for cutting off power when the rolling pin is fully upraised; a plurality of resilient means for counterbalancing all stationary and moving loads, and for keeping the contacts of the momentary stop switch open; a multifunction control handle for raising, lowering, and pressing of the rolling pin, for actuating the momentary stop switch, and for changing the rolling pin stroke length; and a variable speed gearmotor for changing the speed of the rolling pin stroke and for halting the rolling pin at the extremities of its longest stroke.

An electric rolling pin apparatus for making discs of dough comprising: an enclosed mechanism housing structure having four side walls, a top cover plate, and a bottom cover; a motor-driven rotating disc means located on top of said housing structure; a reciprocating rolling pin on top of said disc

An electric rolling pin apparatus for making discs of dough comprising: an enclosed mechanism housing structure having four side walls, a top cover plate, and a bottom cover; a motor-driven rotating disc means located on top of said housing structure; a reciprocating rolling pin on top of said disc means pivotally supported by two arms of a glider protruded upwardly through two parallel slots in said top cover plate, each laid diagonally across and tangentially to the periphery of said disc means; said glider formed into a U shape, having a slider disposed equidistant from its two vertical arms and rigidly secured to its bottom surface by shoulder rivets, leaving a gap between the two, equal to the height of said shoulders; a long slotted drive link disposed within said gap between said glider and said slider with its slot at one end in sliding and rotational contact around one of the shoulders of a centrally located slider pin pivotally disposed between said glider and said slider and held in its position by said shoulder rivets disposed on both sides of its central location; an eccenter having a mating slot to receive a drive shaft of a main drive gearmotor and an eccentric pin rigidly secured at an eccentric distance from the axis of said mating slot; said eccentric pin having its middle shoulder in sliding and rotational contact with the remainder of the long slot in said drive link which is retained in sliding contact between the head of said eccentric pin at the top and said eccenter at the bottom; a rectangular frame-like structure disposed in a horizontal plane within said housing structure having laterally disposed front and rear brackets to form two opposite sides of said rectangular frame structure, connecting a transversely disposed side bracket and a slider guiding means which form remaining two opposite sides; said drive link having its other end pivotally mounted on the horizontal flange of said side bracket and said slider installed within said slider guiding means on the opposite side; and a motor mounting bracket disposed on said frame structure, for rigidly securing said main drive gearmotor under said eccenter with its drive shaft protruding vertically upwards through the mating slot in said eccenter, thereby providing driving means to rotate said eccenter and said eccentric pin, causing arcuate displacement of said drive link about its pivot, resulting in the reciprocatory motion of said slider within said slider guiding means and also of said glider and said rolling pin mounted on it.
