Description: |
| Claim:
This invention relates to power hammer and other blow-striking devices, and some, of its objects are to provide means whereby the stroke of the hammer may be varied while the driving shaft is in motion; to provide means for automatically causing the stroke to become zero when the operator leaves the machine or ceases to control the hammer: and to improve the construction of the machine generally. |
