Abstract
Abstract A multi-motion parts handler including a transfer arm that is mounted for reciprocal movement through the agency of mechanical power derived from a motor or the like, the conveying structure of the arm is further mounted for both reciprocal movement in a vertical direction and oscillating movement in a transverse direction, with both of said movements being derived from a roller gear indexing drive operatively associated with a lower segment of the shaft that mounts the conveying member of the transfer arm. The reciprocal movement of the arm may also be derived from said indexing drive through the agency of a lever communicating with a face cam track provided to one side of the cam and which motivates a second shaft coaxially arranged within said first shaft, or the reciprocating movement to said arm may be acquired from another cam that actuates a follower provided upon said second shaft and which induces its basic lineal reciprocating movement.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
234 words
A multi-motion parts handler for use in transferring a part from one position and through a variety of motions to another and the intended position, including transfer means for use in supporting a part through its variety of said motions, said transfer means including at least one arm capable of reciprocal movement in a lineal direction, means operatively associated with said arm to induce said movement in the said lineal direction, a shaft coupled to said transfer means and disposed for inducing its reciprocating motion in another lineal direction, a roller gear indexing drive operatively associated with said shaft and provided for inducing the transfer means in an oscillating motion, said roller gear indexing drive including in combination an indexing cam and roller follower hub, said roller follower hub being secured to said shaft, means associated with said indexing cam for inducing said shaft and its coupled transfer means into its reciprocating movement in the said another lineal direction, motor means which when energized providing for rotation of said indexing cam and inducing movement of the said means operatively associated with said arm, a speed reducer coupled with said motor means and providing for a reduction in its speed of rotation, whereby upon actuation of said indexing drive and the means associated with the arm said transfer means and its arm is induced into a plurality of movements for precision transfer of a part.
Claim 2
Dependent Claim

A multi-motion parts handler for use in transferring a part from one position and through a variety of motions to another and the intended position, including transfer means for use in supporting a part through its variety of said motions, said transfer means including at least one arm capable of reciprocal movement in a lineal direction, means operatively associated with said arm to induce said movement in the said lineal direction, a shaft coupled to said transfer means and disposed for inducing its reciprocating motion in another lineal direction, a roller gear indexing drive operatively associated with said shaft and provided for inducing the transfer means in an oscillating motion, said roller gear indexing drive including in combination an indexing cam and roller follower hub, said roller follower hub being secured to said shaft, means associated with said indexing cam for inducing said shaft and its coupled transfer means into its reciprocating movement in the said another lineal direction, motor means which when energized providing for rotation of said indexing cam and inducing movement of the said means operatively associated with said arm, a speed reducer coupled with said motor means and providing for a reduction in its speed of rotation, whereby upon actuation of said indexing drive and the means associated with the arm said transfer means and its arm is induced into a plurality of movements for precision transfer of a part.
Claim 3
Dependent Claim
29 words
The invention of claim 1 wherein the means operatively associated with said arm and capable of inducing said reciprocating motion in the said lineal direction includes a cam means.
Claim 4
Dependent Claim
46 words
The invention of claim 2 wherein said cam means operatively associated with said arm comprises a plate cam, said plate cam having an integral face cam track provided to one side and useful for inducing the reciprocating motion of the arm in the said lineal direction.
Claim 5
Dependent Claim
85 words
The invention of claim 3 and including a second shaft, said second shaft being coaxially arranged within said first shaft, said second shaft having a follower provided at its approximate downward end and being engaged with said cam means, the upper end of said second shaft being operatively associated with said arm of the transfer means, whereby the turning of said cam means induces a reciprocating motion of said second shaft which effects the said reciprocating motion of the same arm in a lineal direction.
Claim 6
Dependent Claim
46 words
The invention of claim 4 and including a bell crank disposed within said transfer means and being operatively associated with both the approximate upper end of said second shaft and the said arm for translating the reciprocating motion of said second shaft to the said arm.
Claim 7
Dependent Claim
14 words
The invention of claim 1 wherein two of said motions may occur substantially simultaneously.
Claim 8
Dependent Claim
14 words
The invention of claim 1 wherein two of said motions may occur substantially alternately.
Claim 9
Dependent Claim
28 words
The invention of claim 1 wherein said indexing cam comprises a dwell inside indexing cam having integral face cam tracks provided at least at one of its sides.
Claim 10
Dependent Claim
28 words
The invention of claim 1 wherein said indexing cam comprises a dwell outside indexing cam having integral face cam tracks provided at least at one of its sides.
Claim 11
Dependent Claim
26 words
The invention of claim 1 wherein said indexing cam comprises a dwell inside indexing cam having integral face cam tracks provided at either of its sides.
Claim 12
Dependent Claim
26 words
The invention of claim 1 wherein said indexing cam comprises a dwell outside indexing cam having integral face cam tracks provided at either of its sides.
Claim 13
Dependent Claim
60 words
The invention of claim 1 and including a lever, said lever having follower means provided proximate either of its ends, one of said follower means cooperating with said indexing cam, the other follower means cooperating with said shaft, whereby upon operation of said indexing cam the transfer means is induced into its reciprocating motion in the said another lineal direction.
Claim 14
Dependent Claim
22 words
The invention of claim 12 wherein the portion of said indexing cam cooperating with said lever follower comprises a face cam track.
Claim 15
Dependent Claim
91 words
The invention of claim 13 wherein the means operatively associated with said arm includes a second shaft, said second shaft being coaxially arranged within said first shaft, said shaft having a follower means operatively associated at its approximate downward end and cooperating with said indexing cam, the upper end of said second shaft being operatively associated with said arm of the transfer means, whereby the turning of said indexing cam induces a reciprocating motion in said second shaft which effects a reciprocating motion of the said arm in the lineal direction.
Claim 16
Dependent Claim
31 words
The invention of claim 14 wherein the follower means associated with the said second shaft is engaged within a face cam groove provided at the other side of said indexing cam.
Claim 17
Dependent Claim
