ABRALWI W. HARRIS, OF PROVIDENCE, RHODE ISLAND.

RING-SPINNING MACHINE.

SPECIFICATION forming part of Letters Patent No. 596,016, dated December 21, 1897.

Application filed March 19,1897. Serial No. 628,273. (No model.)

2" 0 all whom it may concern.-

Be it known that I, ABRAM IV. HARRIS, of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Ring-Spinning Machines; and I do hereby declare that the following is a full, clear, and exact descrip tion thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to that class of spinningmachines known as ring -spinning frames, and is an improvement on the E. and A. WV. Harris patent, No. 257,321.

It consists, mainly, in an improved method and means for holding the rings and giving them the desired rotary. motion.

It is fully illustrated in the accompanying drawings.

Figure 1 is a front elevation of a part of each end and a portion of the middle of a ring-frame. Fig. 2 is a top view of a ringrail and ring-rotating devices. Fig.- 3 is a horizontal section of the lower part on line m a: in Fig. 1, showing the arrangement of the center and cross shafts, with the gearing for giving motion to the rings. elevation of the frame, showing the connection between the band-cylinder or main shaft, with the center shaft that drives the rings. Fig. 5 represents a ring-holder bearing separate. Fig. 7 is a vertical section of ring-holder on line 2 z in Fig. 6.

The object of the invention is to produce a simpler mode of giving the rings the desired rotary motion instead of the intermittent or variable rotary motion described in the patent above referred to. The object in view in causing the rings to revolve is fully explained in said patent, and may be briefly stated as being for the purpose of reducing the friction of the traveler on the ring and consequent drag on the yarn in spinning the finer numbers, especially at the time when the yarn is winding on the smaller part of the bobbin or spindle and the draft on the yarn is nearly in the direction of the center of the ring.

In the drawings, A is the machine-frame; D, the spindle-rail; O, the lower rail; F, the roller-beam; R, the center ring-driving shaft.

Fig. 4 is an end 'dle.

Fig. 6 is a top view of the ring-holden.

S S are the vertical ring-shafts. All those parts of a ring-spinning frame not described here, including such parts as the drawingrolls with their gears and devices for giving a vertical reciprocating motion to the ring-rail, may be constructed in any of the ways usual in such machines, the object in omitting them being to simplify the drawings and description of the improvement, and both sides of the machine are alike in construction, though only one is described.

In this method I make a separate support foreach ring-holder to revolve in. (Shown in Fig. It consists of a ring at, having an opening in it into which the ring-holder c, Fig. 6, is nicely fitted to revolve freely. The ring a has alegson each side of proper length to elevate it sufficiently to receive the whirl d, attached to the ring-holder a, under it but above the ring-rail J, to which the support is attached by means of horizontal ears projecting out from the legs, through which screws 0 0 are put and screwed into the ring-rail. The support for the ring-holder is placed across the opening in the rail through which the spindle and bobbin pass and is made adjustable by the enlargement of the holes in its ears through which the screws 0 pass, so it can be set exactly concentric with the spin- To allow the belt n to come in contact with the whirls d on each side, the ears are set nearly lengthwise of the ring-rail, varying sufficiently diagonally to allow the car on one support to lap beyond the ear of the next support and economize the room. The endless belt a is carried along both on the inner sides and outer sides of the whirls d d the whole length of the ring-rail'and make one or more turns around whirls e e, one at each end,held in a double-forked clasp P, attached to the ends of the ring-rail. The whirls e e are fitted to slide easily on vertical shafts S S, which cause the whirls to turn by means of splines 25 25, fast in the shafts and grooves made in the pulleys to receive them.

By reference to Fig. 2 itwill be seen that the belt a is held up close to the whirls cl on the ring-holders by means. of deflector-whirls 'v 1;, held on supports attached to the ringrail and placed between the rings alternately on each side of the rail. These deflectorwhirlso carry the belt in far enough between the whirls d on the ring-holders and, exerting equal pressure on both sides of theringholder, cause it to revolve freely in its support without pressing it against its bearing on either side. This avoids one difliculty found in those plans in which the rings are driven by the bands from the cylinder,whieh drew them over to one side so hard that they would not always revolve because of the great friction in the ring-bearings. A tightening device is attached to the back of the ringrail through which the belt 72. passes to keep tight. It consists of a forked frame m, held by screws through its two feet to the inner side of the rail, and a hollow hub f, which is made large enough inside to receive an open spiral spring 2', and a rod h, carrying a whirl g in a fork in its inner end, passes through the spring. The outer end portion of the rod 71 has a screw-thread made on it, and a milled washer-nut y is fitted to screw on the rod h, and a check-nut b is fitted to screw on the rod outside the washer and prevents the latter from turning when set. Two smaller whirls j are attached to the rail inside the tighteningframe (in the same way as the whirls 'u are) to guide the belt n to and from the whirl g as it passes through the tightener. The vertical spline-shafts S are held at their lower ends in bearings attach ed to a yoke Y, which is bolted to the lower rail C, and at their upper ends by a bearing G, bolted to the roller-beam F. The lower ends of these vertical shafts S have bevel-gears B made fast in them, which engage in like bevel-gears fast on its outer ends of the horizontal cross-shafts H, held in bearings on arms extending out from the yokes y, and bearings attached to the end frame. The bevel-gears B on the inner ends of the shafts H H on each side engage with like bevel-gears fast on a horizontal center shaft R, that is held at each end in bearings that are attached to the end frames A. At one end of this center shaft B it projects outside of the end frame and has a gear L attached to it that engages with the gear N, that receives mo-.

tion from the gear B through the gear on the cylinder or main shaft and the gear 0'.

The operation of the improvements is as follows: The power to revolve the rings is received from the main shaft through the gears O RN" L by the center shaft R, and is conveyed to the side cross-shafts through the bevel-gears B and from the cross-shafts to the vertical shafts S S and the whirls e,which slide up and down on their shafts to follow the motion of the ring-rail J from the whirls e by the endless belt at, which passes along each side of the whirls d on the ring-holders between them and the deflector-whirls, giving a rotary motion to the rings. The oper: ation of the belt-tightener is to draw out the bight of belt that is held around the whirl g when the nut y is screwed farther in 011 the rod h, and the spring 1' gives the belt at a proper tension at all times.

Having thus described my improvements, I claim as my invention 1. In aspinning-frame, the combination of a ring-rail, a revoluble ring, a holder for said ring, a whirl attached to said holder, a support attached to the ring-rail to carry said ring-holder, a belt to drive said ring-holder, a series of deflector-whirls held by said ringrail and arranged to carry the belt in between the ring-holder whirls, vertical end shafts, whirls secured thereon, and means for driving said end shafts, substantially as described.

2. In a spinning-frame, the combination of a ring-rail, a revoluble ring, a ring-holder,

a whirl attached to said holder,a belt, and

whirls to deflect said belt between said whirls on the ringholders, substantially as described.

3. In a spinning-frame, the combination of a ring-rail, a belt-tightening device consisting of a frame fastened to said ring-rail, a hub at the outer end of said frame, a spiral spring held in said frame, a rod passing through said spring, a whirl held in one.end of said rod, and a screw-nut fitted to screw 011 the outer end of said rod, substantially as described.

In testimony whereof I have hereunto set my hand.

ABRAM W. I-IARRIS.

In presence of-- BENJ. ARNOLD, M. E. LAwroN.
