Abstract
Abstract An apparatus is disclosed for inserting elements into a workpiece. The apparatus includes reciprocating feeding means movable between first and second positions for sequentially advancing a supply strip of integrally connected preformed elements towards the workpiece. Actuating means cooperate with the reciprocating feeding means for rotating the reciprocating feeding means when the reciprocating feeding means has reached its second position. During the rotation, the supply strip of elements rotates with respect to the lead element which has been inserted into the workpiece thereby breaking the lead element from the supply strip. As the feeding means, holding the supply strip, rotates back to its initial position, the interaction of the supply strip and the lead element which has been inserted into the workpiece polishes and wipes away any burr that may have remained during the severance. The supply strip may comprise a plurality of integrally connected preformed terminal pins which may be utilized in the electrical and electronics industry after insertion into a substrate such as a printed circuit board, but other supply strips of integrally connected preformed elements may be utilized for application in non-electrical industries.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
59 words
Apparatus for inserting elements into a workpiece; said apparatus comprising: reciprocating feeding means movable between first and second positions for sequentially advancing a supply strip of integrally connected preformed elements toward said workpiece; and actuating means cooperating with said reciprocating feeding means for rotating said reciprocating feeding means when said reciprocating feeding means has reached its said second position.
Claim 2
Dependent Claim
59 words
Apparatus for inserting elements into a workpiece; said apparatus comprising: reciprocating feeding means movable between first and second positions for sequentially advancing a supply strip of integrally connected preformed elements toward said workpiece; and actuating means cooperating with said reciprocating feeding means for rotating said reciprocating feeding means when said reciprocating feeding means has reached its said second position.
Claim 3
Dependent Claim
21 words
The apparatus of claim 1 wherein said actuating means also moves said reciprocating feeding means between its first and second positions.
Claim 4
Dependent Claim
66 words
The apparatus of claim 2 and further including a drive shaft; and wherein said actuating means comprises an over-center linkage assembly having a first end connected to said drive shaft for rotation therewith and a second end operatively connected to said reciprocating feeding means for moving said reciprocating feeding means to its second position in response to an initial period of rotation of said drive shaft.
Claim 5
Dependent Claim
41 words
The apparatus of claim 3 wherein said reciprocating feeding means includes an outstanding projection, and wherein said over-center linkage assembly engages said projection to cause rotation of said reciprocating feeding means during a second period of rotation of said drive shaft.
Claim 6
Dependent Claim
58 words
The apparatus of claim 4 wherein said reciprocating feeding means includes a pivoting feed finger, one end of which is biased towards engagement with said supply strip, said one end positioned to permit relative motion of said feed finger with respect to said supply strip when said reciprocating feeding means is moving between its second and first position.
Claim 7
Dependent Claim
33 words
The apparatus of claim 5 and further including anti-reverse motion camming means for preventing reverse motion of said supply strip when said reciprocating feeding means is moving between its second and first positions.
Claim 8
Dependent Claim
44 words
The apparatus of claim 6 wherein said reciprocating feeding means is located a predetermined distance from said anti-reverse motion camming means when said reciprocating feed means is in its first position, said predetermined distance being a multiple of the length of said preformed elements.
Claim 9
Dependent Claim
43 words
The apparatus of claim 7 wherein said anti-reverse motion camming means is adjustably positioned relative to said reciprocating feeding means whereby said predetermined distance may be varied such that said apparatus may accommodate supply strips of integrally connected performed elements of different lengths.
Claim 10
Dependent Claim
37 words
The apparatus of claim 7 wherein said reciprocating feeding means is longitudinally movable relative to said anti-reverse motion camming means as said reciprocating feeding means moves between its first and second position but keyed for rotation therewith.
Claim 11
Dependent Claim
37 words
The apparatus of claim 6 wherein said reciprocating feeding means is longitudinally movable relative to said anti-reverse motion camming means as said reciprocating feeding means moves between its first and second position but keyed for rotation therewith.
Claim 12
Dependent Claim
66 words
The apparatus of claim 1 and further including anti-reverse motion camming means for preventing reserve motion of said supply strip when said reciprocating feeding means is moving between its second and first positions and wherein said reciprocating feeding means is longitudinally movable relative to said anti-reverse motion camming means as said reciprocating feeding means moves between its first and second position but keyed for rotation therewith.
