ABSTRACT:
An escapement mechanism for advancing a leading one of a row of gravity biased objects supported on a guide comprises a leading stop bracket and a trailing stop bracket pivotally mounted in fixed relation to one another and a piston and cylinder assembly, which pivots the two brackets. The brackets are angularly displaced relative to one another such that at one time, one stop bracket is in the path of the objects to back them up and the other stop is out of the path of said objects. The objects back up against the leading stop bracket and then the piston and cylinder assembly simultaneously pivots the trailing stop bracket into the path of the object immediately behind the leading object and pivots the leading stop bracket out of the path of the leading object to allow the leading object to advance by gravity beyond the escapement mechanism. At a later time, the piston and cylinder assembly simultaneously pivots the leading stop bracket back into the path of the remaining objects and swings the trailing stop bracket out of the path of the remaining objects so that the remaining objects back up against the leading stop bracket.
