Abstract
Abstract A rotary transfer member carries means for picking up a sheet-like article from the top of a supply stack supported within a hopper having an open top and an open bottom. An indexing mechanism includes means for intermittently rotating an output shaft in response to a continuously driven input shaft, and the transfer member is supported for rotation with the output shaft and also for axial movement relative to the output shaft. The transfer member is moved axially in response to linear movement of a follower which engages a cam connected for continuous rotation with the input shaft. Supply stacks of articles are successively elevated into the hopper from an index table by a power driven jack mechanism, and a set of magnets are positioned adjacent the hopper for magnetically spreading and spacing the articles within the upper portion of the supply stack within the hopper.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
184 words
Apparatus for intermittently rotating a head member and for also moving said head member in an axial direction, comprising an input shaft and a tubular output shaft supported for rotation in parallel spaced relation, a first cam mounted on said input shaft, a rotatable cam follower mounted on said tubular output shaft and engaging said first cam for intermittently rotating said output shaft in response to continuous rotation of said input shaft, means mounted on said output shaft and supporting said head member for rotation with said output shaft and for reciprocating axial movement relative to said output shaft, a rod member extending through said output shaft and connected to said head member for reciprocation within said output shaft, a generally cylindrical cam mounted on said input shaft for continuous rotation therewith, said cylindrical cam having a peripheral cam surface disposed generally adjacent the reciprocating path of said rod member, and a cam follower mounted on said rod member and engaging said peripheral cam surface for reciprocating said rod member and said head member in response to said continuous rotation of said input shaft.
Claim 2
Dependent Claim
184 words
Apparatus for intermittently rotating a head member and for also moving said head member in an axial direction, comprising an input shaft and a tubular output shaft supported for rotation in parallel spaced relation, a first cam mounted on said input shaft, a rotatable cam follower mounted on said tubular output shaft and engaging said first cam for intermittently rotating said output shaft in response to continuous rotation of said input shaft, means mounted on said output shaft and supporting said head member for rotation with said output shaft and for reciprocating axial movement relative to said output shaft, a rod member extending through said output shaft and connected to said head member for reciprocation within said output shaft, a generally cylindrical cam mounted on said input shaft for continuous rotation therewith, said cylindrical cam having a peripheral cam surface disposed generally adjacent the reciprocating path of said rod member, and a cam follower mounted on said rod member and engaging said peripheral cam surface for reciprocating said rod member and said head member in response to said continuous rotation of said input shaft.
Claim 3
Dependent Claim
74 words
Apparatus as defined in claim 1 wherein said first cam comprises a set of axial spaced disk-like cam element each having a peripheral cam surface, said rotatable cam follower mounted on said tubular output shaft including means for engaging said peripheral cam surfaces, and said cam elements follower cooperating with said cam to produce rotary indexing movement of said output shaft in one direction in response to said continuous rotation of said input shaft.
Claim 4
Dependent Claim
224 words
Apparatus for intermittently rotating a head member and for also moving said head member in an axial direction, comprising an input shaft and a tubular output shaft supported for rotation in parallel spaced relation, a first cam mounted on said input shaft, a rotatable cam follower mounted on said tubular output shaft and engaging said first cam for intermittently rotating said output shaft in response to continuous rotation of said input shaft, means mounted on said output shaft and supporting said head member for rotation with said output shaft and for reciprocating axial movement relative to said output shaft, a rod member extending through said output shaft and connected to said head member for reciprocation within said output shaft, a generally cylindrical cam mounted on said input shaft for continuous rotation therewith, said cylindrical cam having a peripheral cam surface disposed generally adjacent the reciprocating path of said rod member, a cam follower mounted on said rod member and engaging said peripheral cam surface for reciprocating said rod member and said head member in response to said continuous rotation of said input shaft, said means mounted on said output shaft and supporting said head member including a plurality of parallel spaced guide rods, and a corresponding plurality of reciprocating bearings mounted on said guide rods and supporting said head member for said reciprocating movement.
Claim 5
Dependent Claim
