Description: |
| Original application filed 13 May, 1954, now Patent No. 2,816,485, dated 17 Dec., 1957. Divided and this application 20 Sept., 1957.
Claim:
The primary object of the invention is to provide an "elevator" on which the operator of a large machine tool may ride in ascending and descending the vertical distances he must cover in inspecting the progress of the machine work, making adjustments on cutter tools or tracer mechanisms, and changing cutters or control settings. Transport of the operator is not merely a nice convenience but a real, practical need in very large machine tools, for the fatigue brought about by his climbing, twisting, and crawling over the machine may so diminish the operator's keenness of perception and quickness of action as to bring on a serious mistake resulting in damage to the machine itself or ruination of a workpiece into which much machining time and money has already been invested. |
