Abstract
Abstract A process and apparatus to lift, transfer and position penetrable stock such as resin, fabric, and filled or laminated material by impalement. One or more spearhead elements are driven through the penetrable material. The spears are turned axially and lifted to lift the penetrable material with the spears and present it to a work surface whereupon the spear is again turned or rotated, aligning the barbs or flukes so that a stripper plate easily strips the stock from the spearheads and onto a suitable work surface such as a die. The apparatus comprises one or more quills and each supports a harpoon-like spearhead in an adjustable support. A stripper plate in clearance relation with respect to the flukes of the spearhead is movable independently of the spearhead so that when the spearhead mimicks its entry postion, the stripper plate moves in the direction of the spearhead and forces the penetrable stock off of the harpoon points or spearheads and onto a work surface. The spearhead elements and stripper may be restricted to reciprocal movement such as up and down movement so that templets bearing the stock and dies receiving the stock are movable in a shuttle fashion to unload and load position beneath the spearheads or the spearheads and stripper structure may be movable laterally to a pick-up station and then laterally to a discharge or die loading station where the work surface receives the penetrable stock.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
109 words
A process for the transfer of blanket-like penetrable material including the following steps: positioning an impaling structure above said material; driving said impaling structure to penetrate said material and orienting by rotating the impaling structure to a position transverse of entry to resist withdrawal from said material; elevating said impaling structure whereby said material is lifted and carried with said impaling structure; orienting said impaling structure above a work surface while reorienting the impaling structure by rotation to a position registrable with the entry to allow material withdrawal and stripping said material from said impaling structure to disengage said material therefrom and drop said material onto said work surface.
Claim 2
Dependent Claim
109 words
A process for the transfer of blanket-like penetrable material including the following steps: positioning an impaling structure above said material; driving said impaling structure to penetrate said material and orienting by rotating the impaling structure to a position transverse of entry to resist withdrawal from said material; elevating said impaling structure whereby said material is lifted and carried with said impaling structure; orienting said impaling structure above a work surface while reorienting the impaling structure by rotation to a position registrable with the entry to allow material withdrawal and stripping said material from said impaling structure to disengage said material therefrom and drop said material onto said work surface.
Claim 3
Dependent Claim
88 words
A transfer process for penetrable stock comprising the steps of: placing sheets of penetrable material on a template; positioning said template beneath a plurality of spears and driving said spears through said penetrable material; turning said spears on their axes; lifting said spears and said material impaled thereon from said template; transferring said material to a position over a working surface and turning said spears on their axes to impaling entry position; stripping said material from said spears and onto said working surface; and repeating said operational sequence.
Claim 4
Dependent Claim
88 words
A transfer process for penetrable stock comprising the steps of: placing sheets of penetrable material on a template; positioning said template beneath a plurality of spears and driving said spears through said penetrable material; turning said spears on their axes; lifting said spears and said material impaled thereon from said template; transferring said material to a position over a working surface and turning said spears on their axes to impaling entry position; stripping said material from said spears and onto said working surface; and repeating said operational sequence.
Claim 5
Independent Claim
115 words
An apparatus for piercing, lifting and transferring penetrable material comprising: a machine frame; one or more spears in parallel spaced-apart relation; drive means connected to said spears for selected axial reciprocal rotation of said spears; a support carriage holding said spears; drive means connected to said frame and to said support carriage whereby said carriage is selectively and reciprocably driven on the axis of said spears; a stripper plate surrounding the shank portions of said spears in clearance relation thereto and movable with said carriage; and drive means connected to said carriage and to said stripper plate whereby said stripper plate is movable on the axis of said spears and disengaging material from said spears.
Claim 6
Independent Claim
115 words
An apparatus for piercing, lifting and transferring penetrable material comprising: a machine frame; one or more spears in parallel spaced-apart relation; drive means connected to said spears for selected axial reciprocal rotation of said spears; a support carriage holding said spears; drive means connected to said frame and to said support carriage whereby said carriage is selectively and reciprocably driven on the axis of said spears; a stripper plate surrounding the shank portions of said spears in clearance relation thereto and movable with said carriage; and drive means connected to said carriage and to said stripper plate whereby said stripper plate is movable on the axis of said spears and disengaging material from said spears.
Claim 7
Dependent Claim
53 words
In the combination of claim 3 wherein said frame includes shuttle means and a perforated template thereon for location of said template beneath said support carriage and at a drape loading station; and a work surface also on said shuttle means and positionable selectively beneath said carriage and movable to a work station.
Claim 8
Dependent Claim
41 words
In the combination of claim 3 wherein said carriage is laterally and selectively movable in said frame from a first position over a perforated template to a second position in registry over a work surface upon which said stock is deposited.
Claim 9
Independent Claim
132 words
An apparatus for penetrating, lifting and transferring penetrable stock comprising: an impaling head including a carriage and a plurality of spear support quills selectively locatable on said head; a machine frame supporting said impaling head and said carriage; fluked spear elements adjustably and removably supported in said quills; means connected to the shafts of said quills selectively rotating said spear elements to two positions; a drive element drivably connected to said frame and to said carriage whereby said carriage is selectively lowered and raised in respect to said frame; a stripper reciprocably and selectively movable axially of said spear elements; and a drive element drivably connected to said stripper and to said carriage whereby said stripper is selectively movable on the axis of said spears for removing stock impaled on said spears.
Claim 10
Independent Claim
132 words
An apparatus for penetrating, lifting and transferring penetrable stock comprising: an impaling head including a carriage and a plurality of spear support quills selectively locatable on said head; a machine frame supporting said impaling head and said carriage; fluked spear elements adjustably and removably supported in said quills; means connected to the shafts of said quills selectively rotating said spear elements to two positions; a drive element drivably connected to said frame and to said carriage whereby said carriage is selectively lowered and raised in respect to said frame; a stripper reciprocably and selectively movable axially of said spear elements; and a drive element drivably connected to said stripper and to said carriage whereby said stripper is selectively movable on the axis of said spears for removing stock impaled on said spears.
Claim 11
Dependent Claim
