iMPROVEMENT INYMODE DF ADJUSTING RING S AND RlNG-RAILS lN RING AND TRAVELER SPINNING FRAM ES Specification forming part of Iictters Patent No. 42,829, dated May 24, 1864.

To all whom it may concern:

Be it known that I, J 01m BIRKENHEAD, of llion, in. the county of Herkimer and State of New York, have invented a new and Improved Mode of Adjusting Rings and Ring- Rails in Spinning-Frames; and I do hereby declare that the following is a full and exact-'- dcscription thereof, reference being bad to the accompanying drawings and the letters of referencem'arktd thereon. t

To enable others skilled in the arts toniake and 'use my invention, I will proceed to describe its nature, construction, and operation.

The nature ,of my invention consists in placing an eccentric ring within the ring-rail, and gib-bushes within the holster-rail of spinningi'rames.

In constructing ring rails for spinnin gframes great difiiculty is found in getting the holes for thereception ot' the-ring precisely in the con ter of the rail or concentric with the'spindle. When the hole is not concentric with the spindle the-traveler is caused to bear harder upon one side of the ring, causing the ring to wear and giving the travelera vibrating .motion. The traveler is caused to revolve around the ring by the tension of the yarn, and as its speed should be from six to seven thousand revolutions per minute it is necessary that thus giving that even tension to the yarn which is necessary in producing good and even yarn. -Another great evil is eausedby the wearing of the lifter pin or and shown in the drawings at 0, Figure 1. This wear generally occurs on that ,portion of the rod or pin which is in front of the machine, andnhere my gib-bush becomes very valuable for the purpose of taking up the motion that the lifter rod or pin may have acquired by its wear.

Fig.- 1 is a view showing a portion of a nspinning-frame with my improvements. Fig.

2 is a view showing the eccentric-ring in an inverted'position for the purpose of showing its eccentricity at aand b. Fig. 3 shows a portion of bolster-rail with set-screws f and h.

Fig. 4 is a view of bush (1 with its gib j Figs.

5 and 6, front and edge view of gibs j.

' A. is the'ring-rail; B, the bolster-rail; (J, the lifter-pin; D, the spindle; g, the eccentric-ring;

a and b, the eccentric port-ions'of the ring 9 d, the bush; j, the gin; f and h, the set-screws for holding the bush and gib in position, and a set-screw for holding the ring.

I construct my improvements in the following manner: I first turn my'ring circular as' usual on a true mandrel. 1 then give a slight eccentric form to the outside'of the lower portion of' the ring by turning it upon, a mandrel having centers one side of the true een'ters. thus giving the outer side of the lower portion of the ring the required eccentricity.

The eccentric-rin g isplaecd in whatever hole in the ring-rail ot' the spinning-machine is not concentric with the axis of Y the spindle passing through the ring, and is turned. around until the spindle shall occupy a position precisely in the center of the ring, and it is then secured in its position by means of the set screw c, v

Fig. 1.

- The bush I construct in the ordinary manner, except making, a slot in one side for the reception of the gib, which is made as" shown in Figs. 5 and 6. The bush is then placed in the hole made in the bolster-rail for its reception, and the set-screw f is screwed slightly against the gib, and the set-screw h is screwed firmly against the rear side, of the bush in?" for the purpose of holding it in its proper position. Now, when the lifter pin or rod U becomes worn, the rin g-rail A is thrown toward the front side of the machine, which causes the traveler to have an irregular bearing upon. the ring, thus causing a greatwear of the ring,

increased tension ofthe yarn, and, consequent- 1y, uneven and worthless yarn. With my gib Within the bush d, and the set-screw f to screw against it, the. ring-rail can be brought back to its original position. Whatever spindle may not then be concentric wit-h its respective ringmay be brought precisely concentric by the use of my eccentric-ring. Thus with the combined use of my eccentric-ring and gibbash a spinning machine may hemacle to work very perfectly.

I do not claim as my invention the use of the firing placed within the rail A, neither do 1lgelgtim the bush d independent of the gihj Letters Patent of the United States, is-- l. The employment of the eccentric-ring 9,

What I doelim, and wish to secure by as and for the purpose herein described and set forth. I

2. The combination of the gibj and bush d, substantially in the manner as and for the purpose herein set forth.
