SPECIFICATION forming part of Letters Patent No. 355,823, dated January-11,1887.

Application tiled September 14, ISEF.

To all whom t may concern:

Be it known that l, ALvIN F. JnNKs, of Pawtucket, county of Providence, and State of Rhode Island, have invented an Improvement in Ring-Rails for Spinning and Twisting Machines, of which the following description,`in connection with the accompanying drawings, is a specilication, like letters on the drawings representing like parts.

This invention has for its object to improve, and at the same time simplify and-cheapen, the construction of ringrails for use in spinning and twisting frames, my improved rail, with its attached rings,be ing lighter in weight than usual cast-metal flanged rails now commonly made.

Heretofore in the manufacture of spinningmachines great diiiiculty has been experienced in correctly mounting the ring-rail upon the 2o lifting-rods, such difficulty arising from the lack of trueparallelism of the holes bored through the rail for the reception of the liftingrods, or from the lifting-rods being out of true parallelism,owing to fault in their guides.

In practice the ring-rail must be moved uniformly at each end, and must be restrained from the possibility of either longitudinal or lateral movement when in operation, and the lifting-rods must be free to be moved without 3o binding or cramping in their guides.

In accordance with my invention the ringrail, with 'rings attached, may be quickly applied to the usual lifting-rods without rereaming` the holes, and the rods may be moved freely. v

My improved rail is composed of two narrow metallic bars secured togethenfone above the other, by means of screws or bolts and nuts in such manner as to leave between the said 4o rails a space in which to insert the ring-holding plates, the latter being` clamped between the said bars and extended laterally therefrom, the said plates near their other ends being supplied with rings. The rings are clamped in the said rail before it is applied to the frame, and to enable lthe rail, with its attached rings, to be applied to the machine with the rings in correct position with relation to the spindles, and at the same time enable the ring-rail to 5o be readily combined with or to be attached to Serial No. 213,516. (No model) the usual lifting-rods, so that the latter may be moved freely and without any liability of being cramped or bound in their guides, I have provided my improved ring-rail with one round hole, which will be fitted snugly by one of the lifting-rods,and with a second hole, oblong in shape and ofl enough greater areain cross-section than the lifting-redes to enable the said lifting-rod to enter it loosely, such construction enabling the ring-rail to be read- 6o ily applied to any lifting-rods without reboring the rail or enlarging or rereaining the holes therein.

Providing the ring-rail with one round hole which is a fit for one of the lifting-rods,al1 lia- 65 bility of longitudinal movement of the rail is obviated, while the oblong or larger hole near the opposite end of the rail passes readily down over the other co-operating lifting-rod.

If both of the holes in the rail were a fit to 7o the lifting-rods,the rail could not be so quickly applied.

Figure 1,in front elevation, shows part of a spinning-frame,its liftingrods, and aring-rail applied thereto. Fig. 2, in plan view, broken out to shorten the ligure, shows al ring-rail and attached holders and rings embodying my invention; Fig. 3,a section in the line .fr of Fig.

2; Fig. at, a modification showinglone ring and holder and part of a ring-rail, part of the rail 8o above the holder being broken out; and Fig.

5 is a section of Fig. 4 in the dotted line x.

The frameA, rails B B', and lifting-rods C C', having usual bearings, are and may be all as in United States Patent No. 222,330, or of usual construction common to ring-spinning frames.

The rings a, herein shown as double rings, but which may be of any usual shape, are forced into or otherwise suitably heldin hold- 9o ers c', composed preferably of sheet-steel, slotted as at 2 2.

The rail is composed of two narrow metal bars, b b, preferably of T shape in crosssection (see Fig. 3) for sake ot' lightness, the 95 said bars being firmly clamped together to secure the holders between them by screws b2, preferably two screws for each holder, the said screws also passing through the slots 2 2 in the said holders.

(See Fig. 2.) Instead of roo these screws I may use bolts, as 3, or I may employ rivets, as 4, in Figs. 4 and 5, they entering holes in the holder.

Each rail has a round hole, c, near one end, which is of a diameter to exactly fit the liftingrod 0,130 which it is to be secured; but near its other end the said rail is provided with an oblonghole, o', which is enoughlarger than the lifting-rod to' fit over the other lifting-rod, C. without touching it except at its front and rear sides, as shown in Fig. 2, in which condition the rail may be connected to the said lifting-rods by set-screws d d.

The oblong hole c' obviates any reaming or reboring of the rail, or adjustment of the usual bearings for the lifting-rods G C.

A ring-rail such as described, andprovided with holes, as stated, may be readily applied to the lifting-rods of any spinning-frame of substantially like capacity.

. I do not claim a rail having two round holes or holes of the same area in cross section asA the lifting-rods.

My improved rail may be sold with its rings and ring-holders attached, thus avoiding the trouble in the mill ofsetting and adjusting the rings separately after applying the rail to the machine.

I claim- A ring-rail composed of two bars,one above the other, and provided with one hole, c, to fit one lifting-rod, and with another hole, c', of greater area in cross-section than the liftingrod to enter it, combined with a series of platelike ring-holders extended from one side of the said ring-rail, and with rings held by the said holders, substantially as described.x

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
