Abstract
A blade assembly which, during a single cycle of reciprocation, both halves a pear or the like and cuts out the calyx or equivalent portion thereof. This assembly is shown employed in apparatus which automatically and sequentially functions to halve and remove the calyx from a plurality of pears or the like. Control means is also provided for synchronizing reciprocations of a blade assembly (or a gang of blade assemblies) relative to each of a successive plurality of continuously moving pears or the like.
Claims10
A blade assembly adapted for incorporation into a splitter for pears and the like comprising
- (A) a rigid flattened blade member having a cutting edge portion defined on a side thereof for splitting a pear,
- (B) a shaft support means, including means associating same with said blade member,
- (C) guidance means allowing reciprocal movements of said blade member generally in the plane defined thereby in a direction generally transverse to said edge portion,
- (D) a pair of sheet-like members each conforming generally to a tapered section with the smaller edge thereof having a cutting edge surface defined therealong for removing the calyx region of a pear is split,
- (E) mounting means securing each one of said sheet-like members in opposed relationship to the other thereof and to said blade member with said respective tapered sections defining together generally a conical section and with said blade member extending transversely therebetween, the taper of said conical section extending generally towards said cutting edge portion, said conical section being oriented with said smaller circular edges thereof being in spaced relationship to said cutting edge portion.

A splitter apparatus for pears and the like comprising
- (A) a supporting frame assembly,
- (B) a blade assembly comprising a flattened blade member for splitting a pear, a blade shaft support means associated therewith, and associated bearing means for supporting and guiding said blade shaft support means during reciprocal movements of said blade member relative to an edge portion thereof in a plane generally defined thereby,
- (C) drive means for so reciprocally moving said blade member, including transfer means functionally associating said drive means with said blade shaft including actuation means therefor,
- (D) holder means for positioning and supporting a pear or the like generally axially of said blade shaft,
- (E) a pair of sheet-like members each conforming generally to a tapered section with the smaller edge thereof having a cutting edge surface defined therealong for removing the calyx region of a pear as said pair is split,
- (F) mounting means securing each one of said sheet-like members in opposed relationship to the other thereof and to said blade member with said respective tapered sections defining together generally a conical section and with said blade member extending transversely therebetween, the taper of said conical section extending generally towards said cutting edge portion, said conical section being oriented with said smaller circular edges thereof being in spaced relationship to said cutting edge portion.

Automatic continuously operable apparatus for sequential halving and calyx removal of each of a plurality of pears or the like comprising
- (A) a supporting frame assembly,
- (B) a blade assembly comprising a flattened blade member for splitting a pear, a blade shaft means associated therewith, and associated support means for supporting and guiding said blade shaft during reciprocal movements of said blade member relative to an edge portion thereof in a plane defined thereby,
- (C) first drive means for so reciprocally moving said blade member through predetermined cycles of reciprocal movement, including transfer means functionally associating said drive means with said blade shaft,
- (D) a plurality of holder means, each adapted for positioning and supporting a pear or the like generally axially of said blade shaft,
- (E) a pair of sheet-like members each conforming generally to a tapered section with the smaller edge thereof having a cutting edge surface defined therealong for removing the calyx region of a pear as said pear is split,
- (F) mounting means securing each one of said sheet-like members in opposed relationship to the other thereof and to said blade member with said respective tapered sections defining together generally a conical section and with said blade member extending transversely therebetween, the taper of said conical section extending generally towards said cutting edge portion, said conical section being oriented with said smaller circular edges thereof being in spaced relationship to said cutting edge portion
- (G) continuously movable conveyor means for translating each of said holder means in a fixed path into and away from a predetermined position beneath said flattened blade member,
- (H) control means for synchronizing reciprocations of said blade shaft means relative to each of said holder means as such continuously translate generally tranversely relative said shaft means by said conveyor means, said holder means being in generally equally spaced, longitudinally aligned relationship to one another as respects the direction of such translation.
