Core lamination selecting apparatus
First Claim
1. Apparatus for selecting a predetermined, axial distance of columnar annular laminations having radial slots formed in the annular surface for use in dynamoelectric machine cores comprising:
- supporting means for receiving a plurality of laminations in columnar relation and for supporting one end of the column;
a first member;
first means for mounting said member in reciprocable relation along the columnar axis and for controlling said member in movable relation towards and away from said supporting means along the columnar axis;
a second member;
second means for mounting said second member in reciprocable relation to said first member along the columnar axis to engage the other end of said column and for exerting a selectively releasable force between said first member and said second member to releasably compress the laminations in said column; and
pick-off means for selectively exerting a holding force to at least one lamination spaced a predetermined axial distance from said other end thereby defining a stack of laminations having a predetermined columnar dimension.

Abstract
A supporting mandrel receives a plurality of electrical motor core laminations in columnar relation. An overhead ram carrying a ram head is in movable relation towards and away from the supporting mandrel along the columnar axis. A cylinder is formed in the ram head opening towards the supporting mandrel. A piston is reciprocably mounted in the cylinder and is coupled in force transmitting relation to the upper end of said column. Selectively releasable fluid pressure is operable to move the piston toward the supporting mandrel for compressing the laminations in the column. Coplanar pick-off fingers are mounted in an axially aligned member and are movable in a radial direction relative the axis and exert a holding force to at least one lamination. The plane of the fingers is spaced a predetermined axial distance from the upper column end defining a predetermined stack height of laminations. The holding force is maintained until the fluid pressure to the piston is released. The stack is then lifted and retaining means engage the stack while it is moved to a second subsequent station to prevent droppage of any laminations in the stack.

22. Apparatus for selecting a predetermind axial distance of columnar annular laminations having radial slots formed in the annular surface for use in a dynamoelectric machine core comprising:
-
first means for stacking a plurality of laminatIons to form a column of laminations; second means for applying a compressive force to said column to remove lamination irregularities; third means for gripping a lamination a predetermined axial distance along said column while said second means maintains said compressive force to define a lamination stack corresponding to said axial distance; fourth means for releasing the compressive force while said third means maintains said gripping force; fifth means for separating the lamination stack while said third means is maintaining said gripping force and after said fourth means has released said compressive force.
