Abstract
Abstract A meat slicing machine has a base which supports an inclined rotary knife and a removable reciprocating carriage having an inclined material supporting surface extending parallel to the axis of the knife. The meat is advanced down the surface by a gripper having a plurality of depending prongs engaging the meat and supported by a pivotable arm slidably mounted on an inclined guide rod. The gripper and arm are fed by a follower engaging an inclined lead screw which is indexed during each return stroke of the carriage by oscillation of a one-way clutch having a finger extending for engagement with an adjustable stop mounted on the base.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
191 words
An improved slicing machine comprising a base, an inclined circular slicing knife rotatably supported by said base, a carriage having an inclined surface extending substantially parallel to the axis of said knife and adapted to support material to be sliced, means supporting said carriage for reciprocating movement of said surface adjacent said knife through a feed stroke and a return stroke, an inclined guide rod mounted on said carriage and extending substantially parallel to said surface, a gripping member having a plurality of prongs adapted to engage the material on said surface, an arm pivotally and slidably mounted on said guide rod and supporting said gripping member for lateral movement relative to said surface, an inclined elongated lead screw mounted on said carriage and extending generally parallel to said guide rod, means slidably mounted on said guide rod with said arm and engaging said lead screw to effect lateral movement of said gripping member and movement of the material downwardly on said surface in response to rotation of said screw, and means for indexing said lead screw in response to movement of said carriage for producing slices of precisely uniform thickness.
Claim 2
Dependent Claim
191 words
An improved slicing machine comprising a base, an inclined circular slicing knife rotatably supported by said base, a carriage having an inclined surface extending substantially parallel to the axis of said knife and adapted to support material to be sliced, means supporting said carriage for reciprocating movement of said surface adjacent said knife through a feed stroke and a return stroke, an inclined guide rod mounted on said carriage and extending substantially parallel to said surface, a gripping member having a plurality of prongs adapted to engage the material on said surface, an arm pivotally and slidably mounted on said guide rod and supporting said gripping member for lateral movement relative to said surface, an inclined elongated lead screw mounted on said carriage and extending generally parallel to said guide rod, means slidably mounted on said guide rod with said arm and engaging said lead screw to effect lateral movement of said gripping member and movement of the material downwardly on said surface in response to rotation of said screw, and means for indexing said lead screw in response to movement of said carriage for producing slices of precisely uniform thickness.
Claim 3
Dependent Claim
53 words
A slicing machine as defined in claim 1 in combination with an inclined gauge member positioned substantially parallel to said knife, and said gauge member being infinitely movable in relation to said knife for cooperating with the positive lateral fee of said gripping member to aid in producing slices of precisely uniform thickness.
Claim 4
Dependent Claim
41 words
A slicing machine as defined in claim 2 wherein said means for indexing said lead screw is infinitely adjustable between predetermined limits, and calibration means for correlating the position of said gauge member with the lateral advancement of said gripping member.
Claim 5
Dependent Claim
67 words
A slicing machine as defined in claim 1 wherein said means for indexing said screw include a one-way clutch connected to the lower end of said screw, a second one-way clutch connecting the upper end of said lead screw to said carriage, and an adjustable stop member mounted on said base and cooperating with said first said one-way clutch to effect predetermined indexing of said lead screw.
Claim 6
Dependent Claim
41 words
A slicing machine as defined in claim 1 including means for releasably securing said carriage to the corresponding said supporting means, and said guide rod, said screw and said gripping member all being removable with said carriage to facilitate cleaning thereof.
Claim 7
Dependent Claim
71 words
A slicing machine as defined in claim 1 including pivot means connecting said gripping member to said arm, said means engaging said screw comprise a yoke member including parallel spaced ears slidably mounted on said guide rod with said arm located therebetween, and a spring biased retractable plunger mounted on said yoke member and releasably engaging said screw to provide for lateral movement of said gripping member without rotating said screw.
Claim 8
Dependent Claim
51 words
A slicing machine as defined in claim 1 wherein said screw is positioned below said guide rod, means connected to the upper end portion of said guide rod and rotatably supporting said screw, and said carriage including means for supporting the lower end portions of said guide rod and said screw.
Claim 9
Dependent Claim
30 words
A slicing machine as defined in claim 1 wherein at least one of said prongs comprise a plastic member for engaging said surface of said carriage to protect said surface.
