JAMES BLAIR, OF VORCESTER, MASSACHUSETTS.
SUPPORT FOR SPINNING-SPINDLES.
SPECIFICATION forming part of Letters Patent No. 482,860, dated September 20, 1892.
Application led July 27, 1891. Serial No. 400,780. (No model.)
.To @ZZ whom it may concern:
Be it known that I, JAMEs BLAIR, of Worcester, in the county of Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Supports for Spinning-Spindles, of which the following is aspecification.
The present invention relates to spindles for supporting the bobbins of spinning-machines; and it consists in the means for holding the spindle in the upper or bolster bearing.
The improvements are illustrated in the accompanying drawings, wherein-- Figure l is a central vertical section of the lmprovements. Fig. 2 is a horizontal section herelof in a plane indicated by the line 2 2 in A is a portion of the bolster or spindle rail. Extending through the bolster-rail is the bolster-case B, which has a flange c, resting upon the upper surface of the bolster-rail.
C is an oilcup,`which embraces the lower portion of the bolster-case B and screws onto the same below the bolster-rail. The oil-cup screws tightly against the lower face of the bolster-rail, thereby clamping both itself and the bolster-case B to the bolster-rail. 4
D is the spindle,which extends down through the bolster-case B, and its lower end seats in a spindle-step b, formed in the bottom of the cup C. The bolster-case B at its upper end is slightly contracted and is bored to a true circle to constitute an upper or bolster bearing c for the spindle. The general bore of the bolster-case below the bearing cis slightly greater in diameter than the spindle, so that the latter turns in said bore without friction.
Extending through the flange a of the bolster-case B is an oil-inlet d, which communicates with the annular space between the spindle and the bolster-case, immediately beneath the bearing c. A longitudinal groove f on the interior of the bolster-case conducts the oil from the oil-inlet CZ to the oil-cup O. A screw-plug E lits inand closes the inlet CZ, thus keeping dirt and dust out of the oil-cup. The longitudinal groove f is necessary in order to conduct the oil to the bottom of the oil- 5o cup. The annular space between the spindle and the b01stercase is so small as to be in effect a capillary space, and consequently the oil would not in the absence of the groove f be conducted freely to the oil-cup. On its outer surface, within the bolstercase B, the spindle has a spiral groove g', which carries the oil from the oil-cup to the upper bearing r c for lubricating the latter. Said bearing has on its inner face a groove, which is a continuation of the groove f and which retains the oil pumped up by the spiral groove g.
Above the bearing c the spindle is reduced in diameter, forming a shoulder h. A screwcap F, preferably of brass, surrounds the upper reduced portion of the spindle, having a slight longitudinal play thereon. This cap screws onto and over the top of the bolstercase B and prevents the spindle being accidentally removed from the bolster-case when the bobbin is taken off, since should the spindle be lifted its shoulder 71, would encounter the cap where the latter embraces the contracted portion of the spindle. The cap F has immediately surrounding the spindle a downwardly-extending annular iange m, which lits within an enlarged bored portion or annular recess at the upper end of the bolster-case B and seats against a shouldert' within the bolster-case, which is formed by said enlarged bore or recess. The cap F thus serves to prevent the escape of any surplus oil which may be pumped up to the bearing c by the spiral groove. Any such surplus oil passes into the groove f and is conducted back to the oil-cup.
Above the cap F the spindle carries its driving-pulley G, which is fixed fast thereto.
I claim as my inventionl. The bolster-case B, having an internal bore and a reduced bearing c at its upper end, and the spindle D, extending through the internal bore of said bolster-case and turning in said bearing c,said spindle havinga reduced portion forming a shoulder 7L at the bearing c, in combination with a cap F, removably secured to the upper end of the bolster-case and embracing the reduced portion of the spindle above said shoulder h, substantially as set forth.
2. The bolsteucase B, having bearing c and ICO an annular recesswith shoulder at its upper In witness whereof I havehereunto signed end, anda spindle D, turning insaid bearing my name in the presence o'f two subscribing ro c, in combination with a cap F, screwing onto the exterior of said bolster-case and embracing said spindle, said cap F having a downwardly-extending annular ange m, entering said recess and seatingonsad shoulder z', substantially as set forth.
