IMPROVEMENT IN RING ron SPINNING'.

The Schedule referred to in these Letters Patent and maln'ngp'art o! the lame.

To all whom tt 'may concern:

Figure'l being a view of so much of a spinningflame as is necessary to represent my improvements, andthe same applied thereto.v

4Figure 2, a view, in perspective,'of one of the improved rings, inverted, in position.

Figure 3, a View, in perspective, of a portion of the bolster-rail, to which another feature of my invention isapplied.

Figure 4, .a view, in perspective, of my improved Figures 5 and 6, side and edge views, respectively, ofthe gib which I employ in connection with the said bush. p

' Like letters designate corresponding parts in all of the figures.

In constructing ring-rails for spi lining-frames, great diiiculty is found in getting the holes for the reception of .the rings precisely' concentric with the spindles When the hole is not thus concentric with the spindle, the ring being concentric with the hole, the traveller is thereby made to bear hardest upon one side ofthe ring, causing the ring 4to wear unevenly, and especially giving the traveller a vibratory motion and an uneven tension thereon, the effect of which is to make the yarn uneven, frequently to such an extent as to render it useless.

The traveller is caused to traverse around'the ring by the tension of the yarnyand since its speed is very great, reaching as high as from six to seven, or more, thousand revolutions a minute, the slightest eccentricity of the ring is injurious. I

The ring-holes may be originally eccentric, may become so hy some disturbing lcause in the operation otfthe machine, either in the disarrangement of the ring or ot' the spindle, by wear or other cause.

l' secure the required concentricity of the rings and spindles, in all cases, by the employment of rings withl eccentric bearings, to tit the ring-holes of the frame.

'lhus,.in the drawings, let A represent the ring-rail; B, the bolster-rail; C, the lifter-rod or pin; and D, one of the spindles.

The rings g g are turned as usual, except theirbean ing-flanges, which enter thefholes of the rail. These flanges are turned somewhat eccentric from the main part'of the rings, as indicated at a b, iig. 2.

The degree of eccentricity may be Onlysuicient to compensate for any ordinary degree of eccentricity Vwhich maybe found in the ring-holes 0f a spinningframe, andv diierent rings may have different degrees of eccentricity.

The rings are placed iu the holes of the rails, and if the latter are eccentric, the bearings of the rings are turned round therein until the eccentricity of the one exactly compensates for that 0f the other, so that 4the rings themselves are concentric with the spindles.

The rings are then secured in position by set-screws c c in the rail, made to press against the ring-bearings.

Another dicnl'ty experienced in spinning-frames is caused by the Wearing ofthe lifter-rod Orpin C, in its bush iu the bolster-rail B, the wear generally being on that side of the rod which is toward the front of the machine, and causing the ring-rail to lean forward,

thereby making the rings eccentric in relation to their spindles, with the evil eii'ects ab'ove mentioned.

The object here is to compensate for the wear, which readjustment I accomplish by means of a gib, j, situated in a slot or aperture in one side of the bush d, and bearing against the lifter-rod,'in connection with adj listing-screws f h, in the bolster-rail.

rlhe bush d may be of ordinary construction, except a suitable slot or aperture in one side, to receive the gib j, and retain it in position.

When it is placed in its hole in the rail, one setscrew,f, bears against the gib, and the other, It, against the opposite side of the bush.

A It' the lifter-rod G begins to wear loose in the bush, so as to get ont of proper position, the set-screws are 'adjusted so as to tighten up the rod again, and bring it into the required position to readjust the ring-rait Thus, with the combined use ofthe gib, bushes, and

rings with eccentric bearings, the ring-rail can always be properly adjusted, as well as the individual rings therein.v

What I claim as my invention, and desire to secure by -Letters Patent, is-

A spinning-ring, having an eccentric bearing, substantially as and for the purpose set forth.

Also, the combination of the gib-J and bu` d, substantially as and for the purpose herein set iorth.
