Improved self-balancing centrifugal machine
|
David M. Weston |
Boston, MA |
This invention builds on the inventor's previous patented centrifuge which was intended for drying sugar, patent 63,770 and reissued as 2,845. The major change is to suspend the shaft from the bottom rather than the top. Like the previous patent, this one uses a spring to provide a yielding support for the spring so that it can rotate about its center of mass. This improved centrifuge was manufactured by American Tool & Machine Co. and was popular with textile manufacturers in dying, bleaching and finishing processes. |

Claim:
This invention has for its object to economize time of the workman when the lathe is to be changed to cut a thread of different pitch. Heretofore in screw-chasing lathes the follower has been composed of a metal block adjustably held in a socket of an arm extended from the slide rod, which is connected with and gives horizontal movement to the tool-holding carriage. |
