Description: |
| Claim:
The improved counterbalancing mechanism comprising
the present invention has been designed primarily for use
in connection with machine tools of the type commonly
known as milling machines. The invention, however, is
capable of other uses and the same may, if desired, with
or without modification, be employed in connection with
a . great variety of machine tools having moving parts
thereof which require counterbalancing.
Heretofore planer type milling machines have presented
relatively serious alignment problems occasioned by the
weight of the headstock and its offset or overhanging
relationship with respect to the supporting structure upon
which it is slidably disposed. Briefly, machines of this
type ordinarily include an elongated bed upon which
there is supported a reciprocatory work-supporting table. |
