H. P. WOODMANGY. SUPPORT FOR SPINNING SPINDLES.

HENRY F. WOODMANCY, QF WHITINSVILLE, MASSACHUSETTS.
SUPPORT FOR SPINNING-SPINDLES.
SPECIFICATION forming part of Letters Patent No. 475,994, dated May 31, 1892.
Application filed September 18, 1891. Serial No. 406,114. (No model.)
To aZZ whom it may concern:
Be itknown that I, HENRY F. WooDMAr; CY, of Whitinsville, in the county of I'Vorcester and State of Massachusetts, have invented a new and useful Improvement in Supports for Spinning-Spindles; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming part of this specification.
This invention has roferen cc to an improvement in spindlesupports in which a combined bolster and step-tube is rigidly secured in the bottom of the bolster-case; and it consists in the peculiar and novel construction, as will be more fully set forth hereinafter.
Spinning-machine spindles adapted to be placed on spinning-machines and to be run at high speed require a whirl of limited diameter. In the construction of spindles to which my invention is applicable an upwardextending tube of the bolster-case extends into the whirl. Its diameter is therefore limited, and as the combined bolster and steptube must be of less diameter than the interior diameter of the bolster-case the diameter of this combined bolster and step-tubeis also limited. A supporting or combined bolster and step-tube so constructed and firmly secured for a considerable length in a tapering socket is practically rigid, but under excessive lateral strain will slightly spring, thereby yielding to the strain. With a tight drivingband the splice or knot where the two ends of the band are united exerts a momentary extra strain on the Whirl, the spindle, and the upper end of the combined bolster and step-tube, and this is liable to start a vibration of the spindle. To prevent or limit this springing of the upper end of the supporting-tube is the object of this invention.
The drawing is a vertical sectional View of the spindle and its support.
In the drawing, the numeral 2 indicates the bolster-case, and 3 the upward-extending tube of the same; 4, the sleeve-whirl; 5, the spindle; 6, the supportingtube, rigidly secured in the lower part of the bolster-case and having the step and bolster-bearing for the spindle. This tube 6 is provided with the shoulder 7 and is surrounded by the sleeve 8, which fits loosely on the supporting-tube and rests on the shoulder '7, and also fits loosely in the bore of the bolster-case. The tube 8 may be of the length shown in the drawing; but a shorter length Will practically answer the purpose. As the extra strain of the band caused by the knot or splice is instantaneous and acts as a sudden blow, which starts the tremor of the spindle-blade, and as the space between the tube 8 and the supporting-tube 6 as well as the space between the tube 8 and the inside of the bolster-case are very narrow annular cylindrical spaces filled at all times with oil, these sudden shocks are resisted by the oil, and any excessive strain of the band is limited by the tube 8 coming into contact with the inside of the upwardextending tube 3 of the bolster-case.
Having thus described my invention, I claim as new and desire to secure by Letters Patent The combination, with the sleeve-whirl spindle, the bolster-case provided with the upward-extending tube surrounded by the sleeve-whirl, and the combined bolster and step-tube rigidly secured at its lower end in the bolster-case and provided with a shoulder, of the tube 8, of slightly-less external diameter than the interior of the bolster-case Within the whirl and of slightly-greater interior diameter than the exterior diameter of the combined bolster and step-tube surrounded by it, as described.
HENRY F. WOODMANGY.
