EDMUND TlVEEDALE, SAMUEL TWEEDALE, AND JOSEPH SMALLEY, OF MANCHESTER, ENGLAND.
SPINDLE.
SPECIFICATION forming part of Letters Patent No. 564,905, dated July 28, 1896.
Application filed March 7, 1896. Serial No. 582,285. (No model.) Patented in England October 3, 1891, No. 16,799.
T0 all whom it' may concern:
Be it known that We, EDMUND TWEEDALE, SAMUEL TWEEDALE, and JOSEPH SMALLEY, all subjects of Her Majesty the Queen of Great Britain, residing at Castleton, Manchester, in the county of Lancaster, England, have invented a certain new and useful lmprovem ent in Spindles for Spinning and Doubling Machines, (for which We have obtained Letters Patent in Great Britain under date of October 3, 1891, No. 16,799,) of which the following is a specification.
This invention relates to improvements in the construction of the bolster-tubes of selfcontained spindles, such as are described in the specification to British Letters Patent granted to Samuel Tweedale in the year 1888 and numbered 14, OOO. The object of the present invention is to improve the method of attaching the spring in the above-named specication.
In carrying out our invention we form undercut holes opposite each other in that part of the bolster-tube Where the spring is fixed, the distance between the edges of these holes being made slightlyless than the length of the spring, so that to place the spring in position it has to be bent until the ends enter the holes, when on its being released it assumes the position required.
Referring to the accompanying drawings, Figure 1 is front elevation, partly in section, of a spindle having our improvement applied thereto. Fig. 2 is elevation of the bolstertube and spring. Fig. 3 is a sectional elevation of part of bolster-tube and bolster-carrier drawn to an enlarged scale, and Fig. 4 is a plan of same.
The bolster-tube is represented at 2 lying Within the bolster-carrier 6 in the ordinary manner. On one side of the upper portion of the bolster-tube We form a flattened surface and undercut openings 1into which are inserted the free ends of a bow-spring 3, which, after once being inserted, cannot of itself fall away or become detached. To assist the spring in retaining its position, it may be provided With the ears 3a. This bow-spring is free to move by compression endwise in both directions, according as more or less pressure is put upon the said spring, and it is arranged to project some little distance beyond the outer circumference of the bolster-tube, so as to enter one of the vertical grooves 9, formed Within the bolster-carrier 6, which groove will prevent the bolster-tube from turning around Within the bolster-carrier.
By the use of the undercut openings in the bolster-tube for receiving the free ends of the spring 3 We dispense With the riveting of the spring, and at the same time the removal of the spring is facilitated, and although We prefer to use one spring, more may be used if thought desirable. The pressure of this spring 3 acts in the same direction as the pull of the driving-band 4 on the Whirl S, and this keeps the bolster-tube in contact with the side of the hole in' the bolster-carrier, and as the hole in the bolster-carrier and the periphery of the bolster-tube are made parallel to the center line of the spindle the pressure of the spring tends to maintain the spindle in an upright position by pressing the parallel sides of the bolster-tube and bolster-carrier together. The hole in the bolster-carrier is made larger than the diameter of the bolstertube, and When the spindle is running with an unbalanced load the spring allows the bolster-tube to move slightly and permits the spindle to lind its own center, thus enabling the same to be run at a greater speed Without jar or vibration.
The holes 12 in the bolster-tube are made for the passage of oil to lubricate the parts, which oil is contained within the portion S of the bolster-carrier 6. Y
What we claim is- In combination the spindle,the bolster-tube I 2 in which the end of same is received, the said bolster-tube being provided with openings for the passage of a lubricant, the bolster-carrier 6 surrounding said bolster-tube adapted to contain oil or lubricant, vertical grooves being provided inside the bolstercarrier and at the upper end of same, the upper end of the bolster-tube having a fiattened surface and undercut openings l, 1, adapted to receive a bow-spring, the bow-spring 3 with ears 3a, at the ends of same, for bearing on our hands in the presence of tWo subscribing 1o the flattened surface and retaining it in its Witnesses. position, said spring being adapted to engage 1 with one of the grooves of the bolster-carrier,
5 and the undercut openings allowing it to be JOSEPH SMALLEY readily placed and held in position, and a Whirl attached to and carried by the spindle Witnesses: by which the same is driven. FREDERICK A. VERITY,
In testimony whereof We have hereunto set SAMUEL JACKSON.
