PATENT OEEIGE.

IMPROVEMENT IN RING RAILS AND HOLDERS FOR SPINNING.

Speoilication forming part of Letters Patent No. 135,944, dated February 18, 1.873.

. shows ring G, adjustable ring-holder D, and

cross-sectionof ring-rail A through w y. Fig. 3

is a plan of theadjustable ring-holder D. Figs.

4 and 5 show sections of different kinds ofringsj"V and how applied to ring-holder. Fig. 6 shows twister-rin g and traveler combined withadj ustable ring-holder.

The rail A,shown in Fig. 1, is of`- iron, cast 'with the holes B. It has the grooves C planed so as to receive the adjustable ring-holder l). This holder is made narrower than the space between the grooves, which renders it adjustable by the screws E, and it is also shorter than the distance between the centers of the rings, which renders it adjustable lengthwise of the rail. We, therefore,.can adjust the ring in any direction that may be desired.

An importantfeature of this adjustable ring- Y holder is the slot F. When the sides ofthe holder are not pressed by the screws the slot is open and will allow the puttin gin or taking out of the ring readily. When the ring is in the holder the screws are set up sufficiently to hold the ring fast, and the holder may then be adjusted as required.

By simply loosening one of the screws nearest the slot the ring can b e removed or replaced 5 but the holder can be used with or without the slot F and can be adapted to any kind of ring that is desired to be used, as shown in Figs. 4

and 5. This arrangement is'particularly well adapted to the twister-rin g and traveler, as shown in Fig. 6.

The old method of making the rails without the holder requires great accuracy in drilling the holes for the rings, and bringing them concentricwiththespindlesrequires expensive and nicely-constructed tools for doing the work and skilled and high-priced workmen to construct this part ofthe machine; but by this construction the nicety of workmanship and expense is not required. t

, It is alsowell known among manufacturers and operators of ring-Spinnin g machines that the ring-rail causes more trouble than all the rest ofthe machine, in consequence of the spindles gettin g out ofthe center of the rings, there- Claims.
