RING SPINNING 0R TWISTING MACHINE.

Application filed November 25, 1910.

To all whom it may concern:

Be it known that I, ALoNzo E. RHoADns, a citizen of the United States, and resident of Hopedale, county of \Vorcester, State of.

Massachusetts, have invented an Improve ment in Ring Spinning or Twisting Machines, of which the following description, in connection with the accompanying drawing, is a specification, like characters 011 the drawing representing like parts.

This invention relates to ring spinning or twisting machines and it has more particular reference to the means for guiding the ring-rail in its reciprocation due to the builder-motion, such reciprocation of the ring-rail acting to lay the yarn with the proper traverse upon the rotating yarn receivers or bobbins carried by the usual spindles.

In apparatus of this type the means usually employed for guiding the ring-rail in its reciprocating movement is defective in that there is a tendency for the rail to chatter or vibrate more or less, particularly near the upper end of its stroke, such vibration having an objectionable effect upon the yarn. So, too, there is some tendency of the ringrail to become twisted or deflected out of true.

My present invention has for its object the production of novel and efiicient means for overcoming the objections mentioned, and as will appear hereinafter the means for guiding and preventing twisting or improper vibration of the ring-rail is entirely separate from the actuating connection between said ring-rail and the builder-motion.

I have herein shown my invention as applied to a twister of a well known character, and the novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a front elevation, partly broken out, of a portion of a twister embodying one form of my present invention, the view being taken at the power transmitting end of the frame, the builder-motion and the connections with the ring-rail being shown; Fig. 2 is a transverse section through the frame on the line 22, Fig. 1, looking toward the left; Fig. 3 is a horizontal sec tional detail on the line 3 8, Fig. 2, to show clearly in top-plan one of the rigid connectors between the ring-rails on oppo- Specification of Letters Patent.

site sides of the frame; Fig. 4 is an enlarged sectional detail on the line t-L, Fig. 1, to be referred to.

Referring to Figs. 1 and 2 the inclosed end A of the frame, to protect the gearing, the fixed side rails B in which the twisting spindles C are rotatably mounted, the V615 tically-reciprocating ring-rails D having suitable rings E, the delivery-rolls F mounted in the stands G, at each side of the frame, on the top-board H, the longitudinally movable traverserods I having usual guideeyes J, Fig. 2, and the spindle-driving drum K connected by flexible bands L with the whirls M of the spindles to rotate the latter, may be and are all of usual construction, the drum-shaft in practice being provided with fast and loose pulleys, (not shown).

Referring to Fig. 2 the shafts of the lower front delivery-rolls F have usual attached gears N driven by the large intermeshing gears O, 0 one of which meshes with the pinion P fast on the shaft of the changegear Q, driven in usual manner and carried by the radius-arm R, all of such parts being substantially of Well known construction and forming no part of my present invention. Herein the builder-motion is actuated by a sprocket-chain S driven from the shaft of one of the gears O, and while certain portions of the builder-motion and its actuating means form the subj cot-matter of claims in a co-pending application Serial No. 467,252 filed by me December 12, 1909, a sufiicient part of the same will be herein described to enable the operation thereof to be understood, though my present invention is not restricted in its use merely to the particular builder-motion shown herein, as will be manifest. Said sprocket-chain drives a gear 40 meshing with a pinion 41, see dotted lines Fig. 2, on a short shaft 42 which serves as, and also provides, a fulcrum for the head &3 of a sleevebearing l l in which is mounted rotatably the transmitting shaft l?) having on one end a worm 4:6 and at its other end the bevel-gear e7 driven by a like gear 48 on shaft 42. Worm 4E6 drives a worm-gear &9 fast on the longitudinal shaft 50 supported in the end A and by bracket 51, the traverse cam 52 and hand-wheel 53 being fixedly mounted on said shaft, the cam actuating the builder-motion, all as shown in my application referred to.

The rocker-arms S, S are attached to the transverse rock-shafts T, T, Fig. 1, and shaft T has an upturned arm T connected by a link T with a similar arm T fast on the rock-shaft T, the latter having also the fixedly attached segment V connected by a chain V with the builderarm G7, the follower-roll 68 on the builder-arm cotiperating with the builder-cam 52, all in well known manner. The chain V passes over a guide-sheave V shown in Fig. 1, and the hub 76 of the builder-arm rocks 011 the fulcrum-bar 7a, and as the rotating cam 52 acts upon the follower 68 the builder-arm is oscillated, the down stroke of the latter pulling on the chain V to rock the shafts T, T and thereby elevate the free ends of the rocker-arms S, S.

In my present invention I have dispensed with lifter-rods fixedly attached to and depending from the ring-rail and vertically slidable in bearings on the spindle rail or other fixed part of the frame, said lifterrods resting attheir lower ends on rolls carried by the rocker-arms, as is common in apparatus of this type, and instead of such construction I have provided vertical and fixed guides for the ring-rail, with independent and separate lifter connections be tween the ring-rail and the rockerarms. Each ring-rail D has rigidly attached to it at suitable intervals, depending upon the size and length of the frame, backwardly extended carriers, shown as brackets 1, shaped to clear the rail-flange at the back and then upturned at 2 to support a horizontal stud 3, the bracket being prolonged toward the longitudinal center of the frame from the upturned part 2, to form a head. 1. The head 1 is provided with a heavy bearing boss or hub 5, and a second and similar bearing 6 in alinemcnt therewith is formed on the lower end of a hanger 7 depending from the bracket head 4 and rigidly secured to or forming an integral part of it, said alined bearings sliding upon a vertical guiderod '8. Each guide-rod is seated in a holder 9 fixedly attached to the under side of the top-board H, the guide-rod being secured in said holder in any suitable manner, as by a set-screw 10, and between the bearings 5 and 6 the guide-rod is rigidly connected with the spindle rail 13 by a brace 11 extended from the back thereof, the brace being laterally curved, as shown by the shading thereon in Fig. 2.

By the means described each guide-rod is held fixedly in vertical position by direct connections with the main frame, so that the ring-rail D is guided in a true vertical path during its reciprocating movement, the bearings 5 and (3, which are fixed with relation to the ring-rail, embracing the guiderod above and below, respectively, the brace 11 and sliding upon said guide-rod. As said bearings 5 and G coiiperate with the guiderod at quite widely separated points, one adjacent the ring-rail and the other at a considerable distance below the spindlerail B, it is impossible for the ring-rail to be deflected laterally between or adjacent the several guide-rods. Furthermore, as the bearing 5 is fixed with relation to the ringrail and is adjacent thereto no chattering or vibration of the rail can occur at any point of its traverse, for the guide-rod 8 laterally sustains and guides the bearing 5 at all points of the traverse. The two ring-rails reciprocate in unison, and to still further stilfen them and prevent any tendency of the rails to twist out of true horizontal planes 1 connect them at intervals by rigid connectors. Herein each bracket head 4: has bolted to it the foot 12 of an upright ear 13, and as shown in Fig. 3 the ears are laterally offset from each other, to cooperate with a rigid arched bar or connector 14, cut out at its ends on opposite sides to receive the ears, clamping bolts 15 passing through said ears and the contiguous ends of the connector to rigidly unite the parts.

To accommodate any slight irregularities in the several castings I provide the ears and the ends of the connector 1 1 with slots 16 for the shanks of the bolts, the latter being set up by suitable nuts 17, as clearly shown in Figs. 2 and 3. Thus the two ringrails are rigidly connected to move as a unit, each rail serving to stiffen and brace the other, and in a measure each ring-rail thus is guided in its vertical reciprocation not only by its sliding connection with its own series of fixed guides 8 but also by the fixed guides for the other rail, so that the traverse movement of each ring-rail is smooth and even and wholly free from vibration or chattering at any time.

Lifter rods 18 are pivotally mounted at their upper ends on the studs 3, and each lifter rod has at its lower end a hub 19 which loosely embraces the shank of a headed pivot-pin 20, Fig. 4, reduced in diameter to leave a shoulder 21 which bears against a collar 22 surrounding the pin between the hub 19 and the enlarged end 23 of the rocker-arm, as S. This end 23 has a segmental slot 2% for the reception of the pin 20, and the latter is clamped in adjusted position on the rocker-arm by a nut 25, the adjustment being provided so that each lifter rod 18 may be accurately connected with its particular rocker-arm. When the nut is set up the end 23 of the rocker arm is clamped between the collar 22, and the nut, with the pivot-pin 20 in the desired adjustment, the hub 19 rocking freely on the pin as the rocker-arm swings up and down during the traverse.

From the foregoing description and the drawings it will be seen that the builder-motion effects the vertical reciprocation of the ring-rails by or through the lifter rods 18, and it will be clear that the latter are entirely independent of and separate from the means for guiding the ring-rails in their reciprocating movement.

Inasmuch as the lifter rods 18 have some slight lateral movement about the studs 3 as centers the guide-rod braces 11 are laterally curved, as hereinbefore referred to, to permit such movement. Each lifter rod acts upon the ring-rail adjacent one of its bearings 5 which slides on the guide-rod 8, and any tendency of a lifter rod to twist or distort the ring-rail is counteracted and prevented by the adjacent rigid connection with the opposite ring-rail. As a matter of fact the action of the builder-motion is transmitted directly by the lifter-rods to the opposite and rigidly-connected pairs of railcarrying brackets 1, and as these brackets are positively guided in fixed vertical paths of movement and support the ring-rails the latter are practically relieved from any function beyond that of carrying the rings and effecting the traverse thereof. By this construction and arrangement I obviate any direct strain upon the ring-rail from the action of the builder-motion, and the operation of the machine as a whole is greatly improved.

I have shown and described herein the most satisfactory practical embodiment of my invention now known to me, but the same may be varied or modified in different details of construction and arrangement by those skilled in the art without departing from the spirit and scope of my invention as set forth in the claims hereunto annexed.
