THOMAS MAYOR, OF PROVIDENCE, RIIODE ISLAND, ASSIGNOR TO GEORGE DRAPER & SONS, OF HOPEDALE, MASSACHUSETTS.
SPlNDLE-SUPPORT FOR SPINNING AND TWISTING MACHINES.
SPECIFICATION forming part of Letters Patent No. 454,282, dated June 16, 1891.
Application filed July I 1889. Serial No. 316,177. ,(No model.)
To all whom it may concern:
Be it known that I, THOMAS MAYOR, of the city of Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Spindle-Supports for Spinning and Twisting Machines; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.
This invention has reference to improvements in the bearings for spinning and twist ing machine spindles adapted to single-rail machines.
It consists in a bolster-case provided with a socket, a combined bolster and step tube provided with an enlargement to fit the socket,
the combined bolster and step tube outside the enlargement being of less diameter than the interior of the bolster-case to permit a slight oscillating motion, an elastic packing to resist or limit the oscillating motion of the bolster and step tube, and a sleeve-whirl secured to the spindle above the bolster-tube; also,'in a socketed bolster-case, a combined bolster and step of less diameter at certain points than the interior of said case, thus forming an oil-chamber, and an elongated slit connecting the interior of the combined bolster and step tube with this oil-chamber.
Similar numbers of reference indicate corresponding partsin the drawings.
Figure 1 is aview of my improved spindlesupport and spindle. Fig. 2 isa sectional View through the line A B of Fig. 3. Fig. 3 is a top view showing the driving-band. Fig. 4: is a View of the combined bolster and step tube, showing the packing and the elongated slit for lubricating the spindle.
Spinning and twisting machine spindles are required to revolve at such high speed that the slightest imperfection in the construction or lubrication of the bearings causes heating, binding, thumping, or Wabbling of the spindle. At times all these defects are caused in spindles of the most careful construction; but any one of these defects impairs and often prevents the successful use of the spindle in spinning at the required high productive speed.
- mospheric conditions.
In practical use two elements operate to deflect the spindle from the true axial line, which, to secure perfect yarn, must be at all times and at all points of the length of the spindle-blade exactly in the center of the ring on the reciprocating ring-rail, so that the trav eler is at all times and at all places at the same distance from the axis of the spindle. One of these elements is the lateral strain exerted by the driving-band and the other the strain of the yarn between the traveler on the ring and the spindle or bobbin, particularly when laying the yarn near the upper end of the spindle or bobbin. Other disturbing elements are incident to unavoidable imperfections in the construction and operation of the spindle in practical spinning. A spindle constructed with the best tools is not perfectly round. Neither is its bearing-surface perfectly straight. The bolster and step bearings are only approximately perfect. The spindleblade, if perfectly true when made, is liable to be strained in doftlng. The bobbin is continually changing by use and the varying at- The strain of the driving-band is continually changing, and so is the strain of the yarn on the spindle.
The object of this invention is to so 0011- struct a spindle that the strain of the driving-band and the ever-varying strain in all directions of the yarn will be resisted, while the spindle-bearing may adjust itself automatically to the imperfections of the structure, so as to produce a spindle running perfectly steady without a blur at high speed.
Another object of this invention is to secure perfect lubrication of the spindle, as well as the bearing of the bolster and steptube in the bolster-case.
The spindle consists of the blade 6, the shaft or journal 7, and the pintle 8. To this is secured the sleeve 9, on the lower end of which the whirl 10 is formed. The spindle is supported in the tube shown in Fig. 4. The upper portion 11 forms the j ournal-box in which the shaft 7 of the spindle revolves, and is usually termed the bolster-bearing. The lower end of the tube is closed and forms the stepbearing for the spindle. The projection 13 on this combined bolster and step tube is preferably placed so that when the spindle rests on the step-bearing in the tube the center of Every blow caused by the revolution at high the groove in the whirl 10 or the line of the speed of an imperfectly round or an otherband-pull is on a line with the projection or wise imperfect spindle is cushioned by the 70 enlargement 13 of the combined bolster and yielding packing, the action of which is instep tube. dependent of its own resilience, for as every 14 indicates a yielding ring surrounding a imperfection of construction in the spindle, portion of the combined bolster and step tube. the strain on the yarn being wound on the 15 indicates an elongated slit in the wall spindle or bobbin or an unbalanced bobbin, 75 of the combined bolster and step tube. all revolve with the spindle, the yielding of The bolster-case consists in thebase 16,havthe packing at one instant at any point ining a downward-cylindrical projection 17, the dents the same, so that in the rotation of this lower end of which is screw-threaded.
