Description
@anni @twine JAMES E. BOUTELLE, OF FISHERSVILLE, NEW HAMPSHIRE.
Latas PazmNo. 101,975, dated April 19, 1870.
IMPROVEMENT IN LATHESPINDLE.
The Schedule referred to in these Letters Patent and making part pf the same.
To all whom 'it may concern.
Be it known that I, J AMES E. BOUTELLE, of Fishersville, in the county of Merrimack and State of New Hampshire, have inventeda new and useful Improvement in Lathe-Spindle; and I do hereby declare that the following is a full, clear, and exact description thereof,which will enable others skilled in the art t0 make and use the same, reference being had to the accompanying drawings forming part of this specification.- 1
This invention relates to a new and useful improvement in iathe-spindles for wood turning, whereby heating of the center is. prevented, while it is made selflubxiaiting; and It consists in a. rim-center revolving with the wood to be turned around the stationary center, and in the arrangement for rendering the revolving and the fixed centers self-lubricating, as hereinafter more fully described.
The accompanying drawing represents a view of the invention partly in section.
Similar letters of reference indicate corresponding parts. l
'lhe dotted lines represent asection of the lathe.
A is the spindle.
B is the stationary center or point of the spindle. Y
C is the rim-center, which is tubular inform, and which enters the wood as seen in the drawing, and revolves with the wood around the center B.
D is ascrew in the tubular cellier' O, the end of which enters the grooveE in the stationary center, by which arrangement the rim-center is kept in place. Oron the stationary center when the wood is removed from the lathe.
F is a reservoir, for tallow or other suitable lubricating material, attached to the stationary spindle A. Gis a washer of copper or other suitable metal or material between the end 'of the rim-center and the shoulder of the spindle. The lubricating material is conveyed 'down through the orifice H to the washer G. It passes through notches or recesses under the edgc of' this washer, and lubricates the center B and the rim-center C.
If tallow is used in the reservoir or cup F, suiiicient heat will be generated to melt it as it is wanted, and the parts willvnot heat (iujurionsly) when properly lubricated.
By transferring the point of greatest friction from the wood to the iixed spindle, where lubrication is constant and free, the greatest difficulty experienced by wood-turners is obviated.
It iswell known that the heat generated at the tailccnter of a rapidly revolving lathe is suicient to char the wood, by which thecenter is often varied, and the 'work spoiled or injured.
By lthe use of the revolving rimcenter the fixed center is relieved. No heating or charring of the wood is possible, while the lubrication throughout is perfect.
Having thus described my invention,
I claim as new and desire to secure by Letters Patent- In combination with the iixed center of a lathe, the y
