Abstract
Abstract In a machine for attaching electrical components to a circuit board, wherein each of the electrical components has a body and a pair of generally aligned oppositely extending leads, and wherein the circuit board has preformed holes arranged in pairs to receive the leads of the respective electrical components, a reciprocable ram member cooperates with suitable lead-cutting dies and lead-forming cam means in cutting the leads of the respective electrical components to predetermined lengths, forming the leads so as to permit the leads to be driven through a selected pair of holes in the circuit board, and driving the leads therethrough.

Claim 1
Independent Claim
281 words
In a machine for attaching electrical components to a suitably supported circuit board wherein each of the electrical components has a body and a pair of generally aligned oppositely extending leads and the circuit board has preformed holes arranged in pairs to receive formed leads of the respective electrical components, the combination comprising a reciprocatable ram member, guiding means for guiding said ram member for reciprocating movement with respect to the circuit board, lead-forming cam means mounted for movement between an operative position in the path of said ram member and an inoperative position out of said path and biased to said operative position, and a pair of spaced-apart lead-cutting dies supported at opposite sides of the path of said ram member and adapted to support the leads of the respective electrical components as the respective electrical components are fed one at a time into the path of said ram member between said ram member and said forming cam means, said ram member having a pair of lead-cutting edges adapted to cooperate with said lead-cutting dies to cut said leads to predetermined lengths as said ram member initially moves toward the circuit board and said leadcutting edges engage said leads said ram member further having lead-forming surface means for forming said leads against said lead-forming cam means as said ram member further moves toward the circuit board after said leads have been cut, said ram member being adapted to move said lead-forming cam means to said inoperative position and drive said leads through the selected pair of preformed holes in the circuit board as said ram member further moves toward the circuit board after said leads have been cut and formed.

281 words
In a machine for attaching electrical components to a suitably supported circuit board wherein each of the electrical components has a body and a pair of generally aligned oppositely extending leads and the circuit board has preformed holes arranged in pairs to receive formed leads of the respective electrical components, the combination comprising a reciprocatable ram member, guiding means for guiding said ram member for reciprocating movement with respect to the circuit board, lead-forming cam means mounted for movement between an operative position in the path of said ram member and an inoperative position out of said path and biased to said operative position, and a pair of spaced-apart lead-cutting dies supported at opposite sides of the path of said ram member and adapted to support the leads of the respective electrical components as the respective electrical components are fed one at a time into the path of said ram member between said ram member and said forming cam means, said ram member having a pair of lead-cutting edges adapted to cooperate with said lead-cutting dies to cut said leads to predetermined lengths as said ram member initially moves toward the circuit board and said leadcutting edges engage said leads said ram member further having lead-forming surface means for forming said leads against said lead-forming cam means as said ram member further moves toward the circuit board after said leads have been cut, said ram member being adapted to move said lead-forming cam means to said inoperative position and drive said leads through the selected pair of preformed holes in the circuit board as said ram member further moves toward the circuit board after said leads have been cut and formed.
Claim 3
Dependent Claim
20 words
The combination of claim 1 wherein said lead-cutting edges are continuous with respective opposite side portions of said ram member.
Claim 4
Dependent Claim
30 words
The combination of claim 1 wherein portions of said lead-forming surface means are disposed at an angle leading way, upwardly, from said lead-cutting edges and away from the circuit board.
Claim 5
Dependent Claim
39 words
The combination of claim 1 wherein portions of said lead-forming surface means are disposed at an angle leading away, upwardly, from said lead-cutting edges and away from the circuit board approximately 20* relative to the leads to be cut.
Claim 6
Dependent Claim
58 words
The combination of claim 1 wherein said lead-forming cam means comprises a pair of lead-supporting shoulders adapted to support portions of the leads of the respective electrical components on opposite sides of and adjacent to the bodies of said electrical components after said leads have been cut and while said lead-forming cam means is in said operative position.
Claim 7
Dependent Claim
48 words
The combination of claim 1 wherein said lead-forming cam means is operatively associated with said guiding means in a recess in said guiding means, one surface of said recess serving to limit movement of said lead-forming cam means both toward said operative position and toward said inoperative position.
Claim 8
Dependent Claim
33 words
The combination of claim 6 wherein said lead-forming cam means comprises an axle supported by said guiding means for movement of said lead-forming cam means between said operative posiTion and said inoperative position.
Claim 9
Dependent Claim
73 words
The combination of claim 5 wherein said ram member further has lead-driving surfaces adapted to engage the portions of said leads supported by said lead-supporting shoulders so as to move said lead-forming cam means to said inoperative position and drive said leads through the selected pair of the preformed holes in the circuit board as said reciprocable ram member further moves toward said circuit board after said leads have been cut and formed.
Claim 10
Dependent Claim
54 words
The combination of claim 8 wherein said ram member further has a cavity between said lead-driving surfaces adapted to receive the bodies of the respective electrical components as said lead-driving surfaces engage the portions of said leads supported by said lead-supporting shoulders so as to avoid engagement of said ram member with said bodies.
Claim 11
Dependent Claim
51 words
The combination of claim 1 wherein said lead-forming surface means comprises outer lead-forming surfaces continuous with said respective lead-cutting edges and inclined inwardly from said lead-cutting edges and away from the circuit board so as to be adapted to bend the unsupported portions of said leads inclinedly toward the circuit board.
Claim 12
Dependent Claim
48 words
The combination of claim 10 wherein said lead-forming surface means further comprises inner lead-forming surfaces continuous with said outer lead-forming surfaces and essentially perpendicular to the circuit board so as to be adapted to further bend the unsupported portions of said leads essentially perpendicularly toward the circuit board.
Claim 13
Dependent Claim
40 words
The combination of claim 11 wherein said inner lead-forming surfaces include grooves adapted to receive the unsupported portions of said leads so as to prevent twisting of the leads of the respective electrical components with respect to said ram member.
Claim 14
Dependent Claim
78 words
The combination of claim 12 wherein said ram member further has lead-driving surfaces between said inner lead-forming surfaces and adapted to engage the portions of said leads supported by said lead-supporting shoulders so as to move said lead-forming cam means to said inoperative position and drive said leads through the selected pair of the preformed holes in the circuit board as said ram member further moves toward the circuit board after said leads have been cut and formed.
Claim 15
Dependent Claim
54 words
The combination of claim 13 wherein said ram member further has a cavity between said lead-driving surfaces adapted to receive the bodies of the respective electrical components as said lead-driving surfaces engage the portions of said leads supported by said lead-supporting shoulders so as to avoid engagement of said ram member with said bodies.
Claim 16
Dependent Claim
16 words
The combination of claim 13 wherein said lead-forming surfaces are adapted to assist said lead-driving surfaces.
