DESBROW M. SMITH, OF SPRINGFIELD, VERMONT, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO AMBROSE P. WARFIELD, OF SAME PLACE.
BOLSTER FOR SPINNING-SPINDLES.
SPECIFICATION forming part of Letters Patent N0. 227,066, dated April 27, 1880.- Application filed December 12, 1879.
To all whom-it may concern Be it known that I, DESBROW M. SMITH, of Springfield, in the county of Windsor and State of Vermont, have invented a new and Improved Bolster for Spinning-Spindles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being h ad to the accompanying drawings, and to the letters of reference marked IO thereon, making part of this specification.
This invention is in the nature of an improvement in bolsters for spinning-spindles; and the invention consists in the combination, with a bolster for a spinning-spindle constructed with a tapered sectional and threaded screw-flange, an extension below the flange having a neck, as described,and a cylindrical slitted stem or hearing, of a screw ring-nut, as and for the purpose more particu- 2o larly hereinafter described.
In the accompanying sheet of drawings, Figure 1 is a side elevation of my improved bolster; Fig. 2, a plan or top view, and Fig. 3 a longitudinal section, of same.
Similar letters of reference indicate like parts in the several figures.
The very great velocity at which the spindles carrying the quills revolve gradually wears away the spindle and the interior of 0 the bolsters which, in part, support and steady the spindles as they revolve, causing a loss of motion or play between the spindle and the interior of the bolster, and this lost motion or play, however slight it may be, between the spindle and bolster is very much amplified toward and at the upper end of the spindle, where the quill is fitted, giving a wabbling irregular motion to the quill, and consequently interfering with the regularity of the delivery of the thread and its twist and evenness.
To remedy this difficulty by providing a means to take up this lost motion caused by wear between the spindle and bolster, I construct my bolster A of any suitable metal,
(gun-metal being preferable,) with a flange, B, cast upon it. This flange is recessed in its interior, and its outer sides, a, are tapered and have screw-threads cut thereon. Immediately below this flange, and turned out of the extension I) of the bolster, is a neck, 0. The bolster also has a projection, 0, extending upward above the flange B; but this projection 0 is of less exterior diameter than is the lower part of the extension I).
The flange B and projection c and neck O are divided into vertical sections (1 by slits e. Onto the exterior of the flange B is screwed a screw ring-nut, f, provided with holes 2' formed in it.
The interior g of the bolster is bored out to truly fit the spindle D, which passes throughit.
Now, my bolster, constructed substantially as above described, is operated as follows: When from long use the interior of the bolster or the exterior of the spindle within it, or both, shall have become worn, so that they no longer accurately tit and bear within each other, the slack or play between the spindle and bolster in this way produced is at once taken up by inserting a spanner-wrench in the holesz' in the ring-nutf, and thereby screwing the nut down upon the flange B, and as the nut is screwed down upon the tapered sides of this flange the sectional portions d of the bolster (extending upward from the neck 0) are forced snugly into contact with the exterior of that portion of the spindle D which is within it, and so on for an indefinite number of times may this adjustment be made when necessary. This adjustment is largely due to the effect of the neck 0, which thins the metal of the extension I) sufficiently to enable the several sections 61 to yield as the nut f is screwed down, making each of the sections substantially springs forthis purpose.
Now, it is obvious from the foregoing de- I scription of the construction and operation of my bolster that not only can the regularity of the motion of the spindle be preserved without less of time or expense, but both the bolo ster and spindle maybe used for a much longer time without repair.
The recess formed in the flange B outside of the sections (1 is intended to receive a disk of felt or similar material, to be charged with 5 oil to lubricate the moving surface. This oil may be fed through the oil-hole m or through the several slits 0, forming the sections of the flange B and extensions 1) and 0.
Having now described my invention, what 5 I claim as new, and desire to secure by Letters Patent, is-
A bolster for a spinning-spindle, constructed with an extension, I), and with a slitted flange,
which has tapered and screw-threaded sides, and with a, neck, 0, which is likewise slitted, IO in combination with a ring-nut, substantially asand for the purpose described.
