Engine-lathe
|
Sherman C. Schauer |
Hamilton, OH |
Sherman C. Schauer had been superintendent of the Hamilton Machine Tool Co., which made drilling machines and engine lathes. In late 1898 or early 1899 (certainly by February of 1899) he had left that firm to co-found drilling machine manufacturer Cincinnati Machine Tool Co. It seems likely that this engine lathe was developed while working for Hamilton Machine Tool Co. but we cannot confirm that they actually used it or had the rights to it. We have seen this patent date listed in a 1901 catalog from Lodge & Shipley, for their "Raise-and-Fall Rest". |

Hans Baerbalck |
Hamilton, OH |
Robert S. Carr - patent attorney
My invention relates to relieving mechanisms for engine lathes, of the class adapted for turning fluted reamers or other tools with relieved cutting edges, and the objects of my improvement are to provide means to reciprocate the tool carrier in different horizontal angles of adjustment; to adjust the tool carrier in the direction of its reciprocating movement; to provide means to automatically advance or retard the movement of reciprocation of the tool carrier in relation to the speed of rotation of articles to be turned to register with, a, predetermined helical line thereon; to provide adjustable means to adapt the attachment to relieve the rutting edges of either straight or tapered articles having a predetermined number of either straight or helical flutes, and to adapt the mechanism to a wide variety of engine lathes.

Metal-planer
|
Hans Baerbalck |
Hamilton, OH |
"My invention relates to metal planes, and the objects of my improvement are to provide means for changing the speed of the table in one direction only while its speed in the opposite direction remains constant; to inclose the change gears within the planer bed to protect them from injury and for obviating the usual vibration of the parts; to provide shifting mechanism on the outside of the bed for shifting the change gears separately to prevent them from conflicting; and to provide the most durable, simple and compact construction and assemblage of parts..." |
