RING-SPINNING MACHINE.

SPECIFICATION forming' part of Letters Patent No. 257,162, dated May 2, 1882.

Application tiled February 5, 1881.

"o model.)

To all whom 'it may concern:

Be it known that I, GEORGE RHAZARD, of the city and county of Providence, and State of Rhode Island, have invented a new and useful Improvement in Ring-Spinning lVIachines; and I hereby declare that the following is a full, clear, and exact description ot the same, reference being had to the. accompanying drawings, forming part ot' this specification.

This invention has reference to an improvement in ring-spinning machines constructed to spin the filling-yarn used in weaving, and to wind the same on cops to be used in shuttles.

The invention consists in the peculiar and l novel mechanism by means of which the ringrails of a spinning-machine are reciprocated, so as to lay the yarn to form a cop, either on a bare spindle or on an ordinary cop-tube ot' uniform, ornearl y uniform, diameter, and when the cop is completed return the ring-rail automatically to the point of lowest traverse to commence a new cop or set of cops, as will be more fully set forth hereinafter.

Figure l is a view of the mechanism hy means of which vertical reciprocating motion is imparted to the ring-rail ot a spinning-machine, showing the worm and worm -gear through which and the connecting-gears a slow motion is imparted to the cam controlling the gradual building up of the cop, as also the cam by which the conical layers are laid in close spirals and bound by an open spiral bindingthread, by giving to the rail a slow vertical motion in one and a rapid motion in the opposite direction. Fig. 2 is a top view of part ot' a ring-spinning machine, showing part of the ring-rail as broken away, so as to exhibit the mechanism for controlling the vertical reciprocating motion more fully. Fig. 3 is a side view ofthe mechanism, showing the connection ofthe cams with the lifting-rod connected with the ring-rail. Fig. 4 is an end view ot' my improved mechanism secured to the frame of a spinning-machine, showing the connection fromthemain driving-shafttothe shatton which the cam for laying and binding the cone of the cop is placed andthe gears connecting this shaft with the lower shaft, from which the worm and worm-gear are driven and by which the buildercam is operated. Fig. 5 is a skeleton vie\v,showing the lii'ter-rodotl the ring-rail, the bell-crank, the cam journaled at the upper end of the bell-crank, the laying-cam, and the connection between the two cams. Fig. 6 is a skeleton view ot' most of the parts shown in Fig. 5, seen from the other side, and also showing the latch for locking the bell-crank to the connection between the cams, together with the incline for lifting the latch. Fig. 7 is a sectional view ot' the oop built up by the mechanisni forming the subject-matter of this invention when applied to a ring-spinning machine.

Similar letters of reference indicate corresponding parts.

In the drawings, a represents the ring-rail of a spinning-machine; b, the liftingrod connected with the ring-rail, and c the horizontally-projecting arm of the be'l-crank C, pro` vided with an adjustable stud for supporting the lifting-rod ot the rin g-rail. The hell-crank C is fixed on the horizontal rock-shaft c2, on the farther end of which another arm, c, is secured to support the lit`ting-rod of the ringrail on the opposite side of the frame. A weight, c3, is secured to another arm ot' the rock-shaft c2 for the purpose ot counterbalancing the ring-rails. 'lhe upright arm c of the bell-crank C is supplemented by an upright arm, cw, fixed on the rock-shaft o2 at some distance from the arm c ot' the bell-crank. These two upright arms, c el", constitute a fork ot' the bell-crank. 1n the upper ends of these arms o' c1 of the bell-crank is journaled the cam d, on the shaft orjournal of which is keyed a spurwheel, g3, for driving the cam` with a continuous slow rotary motion from the main driving-shaft e3 through a train of gearing which will be presently described. Cam doperates against an anti-friction roller on the outer end of the link d', the other end of which is pivoted on the stud-pin fixed in the eye of a slide-rod, D, tted in ahorizontal guide, D', Xed to the frame. The sliderod D carries an an ti-friction roller which bears against the face ot' the cam e, fixed on the horizontal shaft, e?, and constructed with a hood, c', for quickly drawing the anti-friction roller of the slide-rod from the widest to the narrowest part ot' the cam.. The cam e, being rotated rapidly, rocks the bell-crank C in one direction, while'the weight of the ring-rails rocks it in the opposite direction, so that. the result will be a constant reciprocation of the ring-rails and the laying of the yarn on the cop in conical layers-bound by,spiral binding-threads laid during the rapid descent of the rin g-rails each time the hood e of cam e passes the anti-friction roller on the slide-rod D. The hood c of the cam c may be dispensed with; but I prefer to use it,"because its presence enables me to more nearly counterbalance the ring-rails. The cam-sha( t c2 is driven from the main driving-shaft c3 by means of a counter-shaft, e4, and the bevel-wheels c5 c c7 e8, as best shown at Fig. 4. As the laying-cam e lays the yarn on the cop in conical layers the cop is gradually built up by the builder-cam d, hung in the npper end ofthe forli of the bellcrank G, as before described, and which gradually changes the traverse of the ring-rails by gradually lifting them until the cop is completed. Rotary motion is imparted to the builder-cam from the main driving-shaft by way of they camshaft e?, connected by a train of spur-wheels,- 1, 2, 3, and 4, to the shaftf, a beveled wheel, ff, on which drivesabeveled wheel, f2, on the worm-shaftf, the worm of which drives the worm-gear g,journaled 011 the rock-shaft c2, and connected with a spur-wheel, g', which drives the spur-wheel g3 on the shaft of the cam (Z through the intermediate spur-wheel, g2, journaled in the fork of the bell-crank C.

rlhe following devices are used for the purpose of controlling the returning of the ringrails from the highest to the lowest traverse. The upright arm c of the bell-crank is provided with a laterally-projecting stud or pin, h, which plays between the projections or stops h h on a slide-rod, h2, fitted to slide horizontally in suitable fixed guides. A block, t', with horizontal ways or grooves formed in its sides, is fixed to the slide-rod h2, and is provided with pivoted switches Z', arranged in said ways. This block Z is embraced by the fork of the lever Z, fulcrumed on the frame of the machine. The fork of said lever is provided with stud-pins which project into the ways of the block Z, and are adapted to pass under the switches 1'. as the slide-rod h2 is moved in one direction, and over said switches when such slide-rod is moved in the other direction. A yoke, Z, is suspended from the lever Z, and in this yokeIare journaled the intermeshing spurwheels Z4 and Z5. The journal of the wheel Z5, being elongated, passes through a sleeve on a hanger-frame, Z2, and ca-rries at its outer'end a spur-wheel, Z, which is driven by a spurwheel, Z8, on the shaftfthrough the intervening spur-wheel, Z7, journaled on a stud on the hanger-frame Z2. The hanger-frame Z2 is pivoted'on the shaft f, and is nearly counterbalanced bythe weight Z3, adjustably fixed on an arm/of said han ger-frame.

' The rack m is fixed on the slide-bar h2 in position t0 be engaged by the spur-wheel Z4. The

rear end of the rack m is constructed with a cam-wheel, mf, as shown in Figs. 1 and 3. The weight of the yoke Zl and its adjuncts and connections tends to hold the lever Z with its studs resting on the lower edges of the ways in the sides of the switch-block t'. As the bellcrank C is gradually turned by the action of the builder-cam d it gradually forces the sliderod h2 in the direction of the arrow shown in Fig. 1 until the free end of the switches t" finally passes beyond the studs of the lever Z by the time the cops have been completed.

The moment the point of the builder-cam escapes from the friction-roller on the link d the ring-rails descend, causing the bell-crank to move the slide-rod ZZ'Z in the direction opposite that indicated by the arrow in Fig. 1, whereby the switches Z are forced under the studs in the fork of lever Z, lifting said lever, and with it the yoke Z', so as to throw the spurwheel Z4 in gear with the rack m. The continuously-rotatin g pinion Z4 then moves the sliderod farther in the same direction until the pivoted ends of the switches Z have passed from under the studs of lever Z, so that it can again descend to the lower edges of the ways in the switch-block, the descent being made positive by the cam-heel m on the rack m depressing the pinion Z4. By the time this is accomplished the ring-rails have descended to the position of lowest traverse and the bell-crank returned to its first position, so that the building up of a new set of cops can be commenced as soon as the iinished cops are doffed or removed.-

The laying-cam and builder-cam are so timed 4with reference to each other that during the highest and last traverse of the ring-rails the point of the-builder-cam escapes from the antifriction roller of link ZZ while the hood of the laying-cam is passing the antifriction roller of the slide-bar D, as shown in Fig. 6. t

In order that the bell-crank may remain with certainty under the control of the layingcam up to the moment of the completion of the cop, and to insure the laying of the last binderthread from thev uppermost end of the cop, I provide the latch 1J, pivoted to the slide-bar D. The hookhead of this latch is elongated, and rests on without engaging the journal ofy the builder-cam during the lower traverses of the ring-rails; but during their higher traverses the latch drops and hooks over said cam-journal at each upstroke of the ring-rails, andlis lifted at each downstrolre by the fixed incline p2 operating on the toep on the latch. when the point ofthe builder-cam, havinglifted the ring-rails to the point of highest traverse, is about to escape from the anti-friction roller of link d the latch p will drop over the jour-y IOO IIO

nal of the builder-cam, and the bell-crank'will .j-l

thus remain under the control of the layer-,cam until the completion of the highest andlast traverse, when the latch is again lifted by inoline p2 releasing the bell-crank, so as to al'- low it toswing or rock back to its rst position and allow the ring-rails to descend to the point of lowest traverse, in readiness, after the dofling of the finished cops, to begin the building up of a fresh set of cops. The journal of the builder-cam moves in slots of links D2, which are pivoted to the slide-bar D and limit the movement of the bellcrank and the descent of the ring-rails.

Fig. 7 (representing a cop built up on this machine) illustrates the different conical layers, commencing on the spindle and gradually enlarging until the angle is reached at which the cop is built up, until completed.

-With this machine filling-yarn can be spun and wound on cops that can be used in shuttles for weaving with great economy.

Having thus described my invention, what I claim as new is l. The combination, substantially as before set forth, of the ring-rail, the bell-crank for supporting it, the builder-cam journaled to the bell-crank, the laying-cam, and the slide-rod and link through which the laying-cam operates on the builder-cam for working the bellcrank.

2. 'lhe combination, substantially as before set forth, of the ring-rail-supporting rocking bell-crank provided with a stud or pin, h, the slide-rod engaged by said pin and carrying a rack, the movable pinion, a yoke for supporting said pinion, the lever from which the yoke ofthe pinion is suspended, and the switch on the slide-rod for lifting said lever to throw the pinion in gear with said rack.

3. The combination, substantially as before set forth, of the ring-rail-supporting rocking bell-crank provided with a stud or pin, h, the slide-rod engaged by said pin and carrying a rack constructed with a cam at its heel, the movable pinion, a yoke for supporting said pinion, the lever from which the yoke of the pinion is suspended, and the switch on the sliderod for lifting said lever to throw the pinion in gear with said rack.

In witness whereof I have hereunto affixed my name.
