A. HOUGHTON, OF PUTNAM, CONNECTICUT, ASSIGNOR TO HIMSELF, AND EBENEZER D. DRAPER AND GEORGE DRAPER, OF MILFORD, MASSACHUSETTS.

SPINNING-FRAME.

Specification of Letters Patent No. 20,920, dated July 13, 1858.

T0 all whom t may concern:

Be it known that I, AMASA HOUGHTON, of Putnam, in the county of vWindham and State of Connecticut, have invented an Improved Bolster for Spindles of Spinning- Frames; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which- Figure l, denotes a front elevation, and Fig. 2, a vertical section of a spindle and a bolster rail having my improvement applied to them.

The ordinary bolster of the upright spindle is nothing more than either a narrow hole through the bolster rail or a tube projecting through and from the said rail, the spindle passing through the bolster and revolving therein when in use. In lubricating such a bolster, much waste of oil is experienced, as the oil on being poured into the bolster can flow freely downward between the same and the spindle, and run down onv that part of the spindle which is below the bolster.y The result is, that with a spindle having a revolution of six thousand times in a minute, it will be necessary to apply oil to the bolster about three times in each twelve hours, or once every four hours while 'it may be in operation.

My invention not only effects a great saving of oil, but experience has demonstrated that when it is applied to a spindle, the latter may be run about four weeks with butI once oiling.

The nature of my invention consists in combining' and arranging with the upright spindle and bolster a cup or oil receptacle vsuch being made to extend below and concentrically around the bolster and to project from the spindle.

In the drawings, A denotes the spindle; B, the bolster rail; C, the bolster extending through and below the bolster' rail and formed tubular and with the lower portion of its outer surface taperingas shown at a, a, in Fig. 2. The spindle works in the bolster in the usual way, and has a cup D, extending from it and around it and the bolster, the arrangement of such cup being as shown in Figs. l, and 2, a shoulder b, Z), of the bolster serving as a cap or cover to the cup while the spindle is in use. rIhe upper part of the bolster is grooved around the spindle or formed in the ordinary way with a channel c, for reception of oil.

In the operation of my invention, the lubricating Huid when lpoured into the channel c, will flow down between the bolster and the spindle and into the cup D. When the spindle is putin rapid revolution the oil within the cup by reason of the action of centrifugal force will be made to rise up, more or less between the spindle and the bolster, and so as to keep th-e rubbing surfaces continually lubricated.

That I claim as my invention is- The application of t-he cup to the upright, spindle and the bolster so as to operate lherewith substantially in manner as speci- In testimony whereof, I have hereunto set my signature.

AMASA HOUGH'ION.
