WILLIAM T. CARROLL, OF \VORGESTER, ASSIGNOR TO GEORGE DRAPER 85 SONS, OF HOPEDALE, MASSACHUSETTS.
BOLSTER [FOR SPINNING-SPINDLES.
SPECIFICATION forming part of Letters Patent No. 357,977, dated February 15, 1887.
Application filed November 5, 1886. Serial No. 218,078. (No model.)
To all whom it may concern.-
Be it known that I, WILLIAM T. CARROLL, of Worcester, county of \Vorcesteryand State of Massachusetts, have invented an Improvement in Bolsters for Spinning Spindles, of which the following description, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.
This invention has for its object to improve the support of that class of spindles known as top spindles, or a spindle which has but a single bearing and that at its lower end below the whirl, the pintle of the spindle running in the bolster which is held loosely in the bolstercase, but is prevented from rotation in the said bolster-case with the spindle.
Prior to myinvention the bolsters employed in bolster-cases have been composed of a metal tube formed by casting and boring a piece of Iron.
In accordance with my invention the bolster is composed of two, but it maybe two or more, concavo convex shells, which are inserted loosely into a sleeve like portion of the bolstercase, the said sleeve-like portion being herein shown as screwed into a shank portion,which in turn is attached to the bolstcr-rail, the lower end of the sleeve-like portion of the bolster case being provided with a nut which is fitted into its lower end, the said nut serving to support the bolster, and having, as herein shown, a projection to enter a slot at the lower end of the bolster, the projection and slot restraining the bolster from rotation with the spindle.
My invention consists, essentially, in the combination,with aspindle and a bolster-case, of a bolster composed of two or more concavoconvex shells extended longitudinally in the bolstencase between it and the pintle. WVith the foregoing I combine means to prevent the rotation 'of the bolster with the spindle.
Figurel in vertical section shows a sleevewhirl and bolster and bolster-rail embodying my invention, the spindle and nut referred to as having a projection to restrain the bolster from rotation with the spindle being in elevation. Fig. 2 is a detail showing in side elevation the said spindle and nut, and Fig. 3 is a plan view of Fig. 2.
The bolsterrail A, having ahole in the usual manner, receives within it the shank portion B of the bolstercase, the same being held in place by the usual nut, 13*. The shank portion B is screw-threaded, as at 2,to receive the screw-threaded lower end of the sleeve-like portion B, the said sleeve-like portion and shank portion B constituting the bolster-case.
My improved holster is herein shown as composed of two concavo-convex shells, at 6, formed of either cast or wrought metal, they being of sufficient length to extend from near the upper end of the bolster-case down to the foot of the spindle, and constitute the lateral bearing for the spindle.
The sleeve-like portion B of the bolster-case is so chambered, as herein shown, as to leave a shoulder, 3, against which may act the upper end of the bolster to thereby prevent the lifting of the bolster from the upper end of the 7 said sleeve-like portion, the bolster when inserted in working position being passed into the lower end of the said sleeve-like portion, and thereafter the nut G is screwed into the lower end of the sleeve-like portion B, the
Fig. 2 shows this projection as the nut, comprises the foot-rest for the spiudie, or a washer might be dropped into the tube to serve that purpose.
A bolster composed of concavo-convex shells such as shown may be made more cheaply than a bolster which is tubular throughout, and a 9 two-part bolster may be readily changed should one part become worn more than the other.
By making the bolster in two parts, divided longitudinally with relation to the length of the spindle, the said bolster entering the bolster-case loosely, the bolster acts the more thoroughly as a cushion to take up and neutralize the vibrations given to the foot of the spindle when rotating rapidly under an unbalanced load.
whirl spindle combined with a bolster composed of independent separable concavo-convex shells inserted within the said sleeve-like portion from its lower end, and with a nut to support the bolster and constitute a footstep for the spindle, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
WILLIAM T. CARROLL.
