Abstract
Abstract The invention relates to nailing apparatus for use in making cable reel flanges or the like. Apparatus according to the invention comprises a rotatable element housed in a work support table of the apparatus and movable to cause a work-engaging surface of the element to raise a workpiece from a support surface of the work support table into a position in which the work-engaging surface supports the workpiece and provides a turning center so that the workpiece can be easily turned relative to nailing means of the apparatus.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
130 words
Nailing apparatus for use in making cable reel flanges or the like comprising a work support table having a support surface on which a workpiece having portions which require nailing can be supported, nailing means operable to insert nails into a portion of a workpiece supported on said surface of the work support table, a rotatable element having a work-supporting surface and a work-engaging projection extending from the work-supporting surface, the rotatable element being housed in the work support table, and means for raising the element into a position in which the work-supporting surface thereof supports the workpiece and said projection provides a rotatable center about which the workpiece can be turned between operations of the nailing means to present said portions of the workpiece successively to the nailing means.
Claim 2
Dependent Claim
130 words
Nailing apparatus for use in making cable reel flanges or the like comprising a work support table having a support surface on which a workpiece having portions which require nailing can be supported, nailing means operable to insert nails into a portion of a workpiece supported on said surface of the work support table, a rotatable element having a work-supporting surface and a work-engaging projection extending from the work-supporting surface, the rotatable element being housed in the work support table, and means for raising the element into a position in which the work-supporting surface thereof supports the workpiece and said projection provides a rotatable center about which the workpiece can be turned between operations of the nailing means to present said portions of the workpiece successively to the nailing means.
Claim 3
Dependent Claim
21 words
Nailing apparatus according to claim 1 wherein said rotatable element is rotatably mounted on said means for raising the rotatable element.
Claim 4
Dependent Claim
26 words
Nailing apparatus according to claim 2 wherein said work-engaging projection is a locating pin adapted to fit into a central aperture in a cable reel flange.
Claim 5
Dependent Claim
73 words
Nailing apparatus according to claim 2 wherein the apparatus also comprises a presser member in opposed relationship with the rotatable element, the presser member being relatively movable toward the element, in the operation of the apparatus, to apply pressure to the rotatable element to lower a workpiece supported thereby onto said support surface of the work support table thereby ensuring that the workpiece is on the support surface when the nailing means operates.
Claim 6
Dependent Claim
31 words
Nailing apparatus according to claim 4 wherein said presser member is mounted on said nailing means so that it applies pressure to the turning element upon operation of the nailing means.
Claim 7
Dependent Claim
42 words
Nailing apparatus according to claim 2 wherein said means for raising the rotatable element comprises pneumatic means energizable, in the operation of the apparatus, to continually urge the rotatable element in a direction to raise a workpiece on the work support table.
Claim 8
Dependent Claim
54 words
Nailing apparatus according to claim 6 wherein a plurality of freely rotatable ball members are housed in the work support table and, the apparatus comprises pneumatic means actuatable, in the operation of the apparatus, to urge the ball members into operative positions in which they project above said surface of the work support table.
Claim 9
Dependent Claim
31 words
Nailing apparatus according to claim 7 wherein said nailing means is operable to press a workpiece onto the work support surface thereby pressing said ball members out of their operative positions.
