44 1 k 1 0O 5 7.0 2 s NITE LEANDER J. MURRAY, OF MILFORD,
MASSACHUSETTS, ASSIGNOR TO THE SAWVYER SPINDLE COMPANY, OF BOSTON, MASSACHUSETTS.
SPINDLE AND BEARING.
SPECIFICATION forming part of Letters Patent No. 579,118, dated March 16, 1897.
Application filed October 26, 1896. Serial No- 610,07'7. (N0 model.)
T0 at whom, it may concern Be it known that I, LEANDER J. MURRAY, a subject of the Queen of Great Britain, residing at Milford, county of Worcester, State of Massachusetts, have invented an Improvement in Spindles and Bearings, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.
This invention relates to that class of spinning spindles and bearings wherein the spindle has a tapering pintle which enters a tapering hole in the bolster, a step being connected by a screw-thread to the lower end of the bolster, rotation of the step relatively to the bolster preserving the proper contact be tween the bolster and spindle.
In United States Patent No. 490,245, dated January 17, 1893, the occasional binding between the pintle of the spindleand the bolster is obviated by connecting the bolster and step by a spring the normal stress of which is sufficient to prevent rotation of the bolster relatively to the step due to the friction of the spindle in the bolster. Should the spin dle stick or bind, however, sufficiently to r0- tate the bolster relatively to the step against the stress of the spring, the bolster would be lowered away from the pintle to thereby reduce the friction.
In this my present invention I utilize the spring connecting the bolster and step to not only perform the function herein described, but also take the place of the usual packing interposed between the bolster and bolstercase and acting as a lateral cushion for the bolster.
Figure 1, in vertical section, represents a spindle and its support containing a bolster and step embodying my invention; and Fig. 2 is a side elevation of the bolster, step, and controlling-spring.
The rail A, bolster case or support B, mounted thereon and secured in place by a nut B, the sleeve-whirl spindle S, having a tapering pintle, the bolster b and the step 5 secured thereto by a threaded shank s to engage the thread I) of the bolster, andthe means for supplying oil to the spindle are and may be substantially as shown in said patent.
I have connected the bolster Z2 and step 5 by a spring S coiled about the exterior of the bolster at the reduced portion 1) thereof, the end 2 of the spring entering a groove b in the bolster, its other end 3 entering a notch or groove 8X in the step.
Preferably a plurality of retaining-grooves b are formed in the bolster (see Fig. 2) to facilitate adjustment of the step in the bolster.
As best shown in Fig. 1, the portion of the spring surrounding the bolster takes the place of the usual packing interposed between the bolster and its case B and affords some free dom of movement therebetween, acting as a yielding medium and forming a lateral cushion for the bolster. The spring also serves to lock the bolster and step together in a yielding manner.
The spring is so applied that it is adapted to be Wound tighter as the spindle is rotated in the direction of spinning, but under ordinary circumstances the spindle running with proper freedom will not turn the bolster to further tighten the spring. Should the spindle stick or bind, however, the partialrotation of the bolster will cause the spring to be tightened sufficiently to lower it on its step and away from the pintle of the spindle, reducing the friction.
By my invention I obviate the use of a separate packing for the bolster and at the same time maintain a yielding lock or connection between the bolster and step.
I-Iaving fully described my invention, What I claim, and desire to secure by Letters Patout, is-- A bolstencase, a bolster therein having at its upper end a cylindrical head to loosely fit the case, said bolster also having a tapering bore, a spindle having a tapering pintle to enter therein, the body of the bolster being externally reduced in diameter, a step having a threaded shank to engage the lower end of the bolster, and a spring surrounding the reduced body of the bolster between it and name to this specification in the presence of the bolster-case, to form a yielding lateral two subscribing Witnesses.
cushion for the bolster one end of the spring his being attached to the bolster-head and its LEANDER ii 5 other end to the step, to form a yielding lock yv therebetween, substantially as described. HERBERT MANLEY In testimony whereof I have signed my GEO. OTIS DRAPER
