Vintage Machinery entry for E. W. Bliss Co.

Description: |
| This improvement is particularly applicable to presses used for extruding where the start of the extrusion portion of the press stroke causes a serious shock force, which limits the speed at which the press can be run. This improvement provides a variable stroke that slows down the initial part of the extruding process and then speeds up. |
