Abstract
Abstract A device for limiting the travel of an arbor press when pressing inserts into a panel. Two insert halves are pressed into a panel from opposite sides by means of an upper and lower anvil. The press movement is stopped by the device when a specified gap between the insert head and the exterior surface of the panel is obtained, compensating for any variations in the panel thickness.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
171 words
A press anvil position control comprising: a lower anvil adapted to be located on a first side of a panel workpiece; an upper anvil adapted to be positioned adjacent to the second side of said workpiece opposite said lower anvil; said anvils adapted to relative movement toward and away from each other; a compensator body mounted on said upper anvil for movement therewith; a pin slidably mounted on said body for reciprocating movement substantially parallel to the path of anvil relative movement, said pin adapted to contact a workpiece between said anvils as said anvils undergo relative movement toward each other; a switch bar mounted on said pin with its major axis substantially normal to said pin; and a limit switch mounted on said body and disposed for operation by said switch bar after said pin contacts said workpiece during relative movement of said anvils toward each other; whereby said switch may control said anvil movement to stop said movement with said anvils at a selected position relative to said workpiece.
Claim 2
Dependent Claim
171 words
A press anvil position control comprising: a lower anvil adapted to be located on a first side of a panel workpiece; an upper anvil adapted to be positioned adjacent to the second side of said workpiece opposite said lower anvil; said anvils adapted to relative movement toward and away from each other; a compensator body mounted on said upper anvil for movement therewith; a pin slidably mounted on said body for reciprocating movement substantially parallel to the path of anvil relative movement, said pin adapted to contact a workpiece between said anvils as said anvils undergo relative movement toward each other; a switch bar mounted on said pin with its major axis substantially normal to said pin; and a limit switch mounted on said body and disposed for operation by said switch bar after said pin contacts said workpiece during relative movement of said anvils toward each other; whereby said switch may control said anvil movement to stop said movement with said anvils at a selected position relative to said workpiece.
Claim 3
Dependent Claim
30 words
The device of claim 1 further comprising an adjustment screw in threaded engagement with said switch bar and located to contact said limit switch during a portion of said travel.
Claim 4
Dependent Claim
37 words
The device of claim 2 wherein said compensator body is slideably mounted on said upper anvil, and further comprising a set screw in threaded engagement with said compensator body for tightening said body to said upper anvil.
Claim 5
Dependent Claim
25 words
The device of claim 3 further comprising a compression spring disposed between said pin and said body for biasing said pin in an extended position.
