SELF-ACTING Muts ron SPINNING.

Specification of Letters Patent I No. 11,279, dated July 11, 1,854.

T0 all whom it may concern: j

Be it known that I, GEORGE WRIGHT, of New England Village, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improve-l ments in Self-Actor Mules for Spinning;

and I hereby declare the following t-o be a full, clear, and exact description of the same, reference being had to the accompanying' drawings, making part of this specification, f

Y whenever the machine is in operation and in which- Figure l, is a plan with the carriage taking out; Fig. 2, a side View; Fig. 3, an

end view of the hand stock; Fig. 4, a view of the other end of the mule; Figs. 5, 6 and 7, details which will be hereafter referred to. j

The nature of my invention `consists in; transmitting the power which actuates thef mule in its and out motions through cone` pulleys, in combination with some means of automatically shifting the band upon the cones, by which means a great saving of- -machinery is effected `andI am enabled to give to the carriage a varying velocity, suited to the requirements of the different parts These drums carry the endless chains or of its traverse.

My invent-ion furthermore consists in, backingoff the yarn at the moment the spindles are stripped by means of a friction f clutch and stationary band which are brought into action by the rising of the stripping wire and operated by 'the'last moj tion of the carriage as it takes out. My invention also consistsvin winding on f the yarn as the carriage takes in by means of the aforesaid clutch and cord which clutch is regulated in its bite by the tension Of the yarns, so that when the strain` upon the latter becomes too great the underfaller wires is depressed, 'thereby opening' the clutch and permit-ting the cord which drives the spindles `to slip and thus regulating the degree of tight-ness with which the yarn is wound. I

scribe its construction and operation.

A is the head stock, B the floor.

C is the main driving Vpulley lupon the shaft D from which motionis communicated through the band E tothe operating parts of the machine. l

F is a pulley made fast to the shaft G upon which also revolves the loose pulley `H. Upon the same shaft is secured the ratchet wheel a with which the pawl Z9 pivoted to To enable others skilled in the art to make l and use my invention, I will proceed to def the pulley is kept in contact by the spring c.

Vhen the band E is upon the drum F the shaft Gr is driven in the direct-ion indicated 4 by the arrow in Fig. 2, and the loose pulley H remains stationary. When the band is shifted upon the pulley H the pawl b engages with the ratchet wheel L and the shaft Gr is driven in the same direction, so that the shaft G 1s driven constantly and uninterruptedly in one and the same direct-ion whether the driving band be upon one or the other of the pulleys F and H. `Upon the shaft Gr is also secured the cone I, the corresponding cone K, being secured to the shaft L which runs in boxes in the end of the carriagey ways M, or in other suitable bands P, whichv take the carriage in and out. These bands pass over carrying rollers Q, which run upon studs projecting from the carriage ways M.

R are arms pivoted to the carriage at g.

and secured to the endless band P at h, by

which means, as the endless band revolves the carriage will be taken in and out.

The speed of the carriage is to be so varied that it shall `move out with a velocity suited to the proper performance of the spinning operation, take in at a much more rapid rate to economize time, and have its velocity checked immediatelybefore it reaches the head stock to prevent breakage, etc. This variation in the speed of the carriage is effect-ed 'in the following manner. T is a horizontal shaft-carrying the arms U, V, which is connected `with an arm W project.- ing from the `belt-shipper X which regulates the position of the belt Y. Z is a lever of the form represented in Figs. l and 2 secured firmly beneath the botto-In of the carriage. A is another lever pivoted at z' to thelbottom of the carriage. One end of this lever is borne up against the lever Z by the spring 71: as seen in F l, thus forming a switch'which may be opened by pressure in one direct-ion but not in the other.

When the carriage commences to take ried into the position shown in dotted lines' in Fig. 3, and the carriage takes in with its fast motion. Before it arrives at the inner y' end of its stretch, the lever Z upon the carriage strikes the arm U and presses it over again into the position seen in Fig. l, and the speed of the carriage is'thus retarded beforeit reaches the head stock, the band Y being left in the position required to take the carriage out with its slow motions.

I will now describe the manner in which the spindles are driven as the carriage takes out..

The belt shipper B which governs the lbelt E is attached to the vibrating shaft C from which rises the arm Z. Beneath the carriage is secured a metallic plate having two inclined edges m, n, by which means the belt is shipped at the proper time as will be hereafter described. The twist pully D is secured to the loose pulley H. While the carriage is taking in the belt E runs upon the fast pulley F, and the pulley vH no l longer driven by the'belt is left free to turn asdriven by the cord E, the winding on being accompilshed by other mechanism which will be hereafter described. When the carriage has reached the forward end of its stretch, the inclined edge m upon its under surface strikes against the pin p upon the belt shipper B and the belt E is thrown upon the pulley H, and the spindles are thus made to revolve as the carriage takes out. The cord E after leaving the twist y pulley D passes around the lofer disk of the friction clutch F, thence around the guide ypulley Q, upon the carriage and over the stationary guide pulley Gr, thence around the Y' intermediate pulley H 'which runs freely upon the spindle t of the friction clutch F, thence around the driving drums I from which motion is communicated to the spindles r by means of the bandsK. The spins dles are thus driven as the carriage takes out, and as the latter reaches the end of its stretch, the incline n upon-its under surface strikes against the arm Z of the shaft C', and the belt E is shifted onto the pulley F, and the spindles are no longer driven by the twist pulley D. i

The yarn is partly stripped and partly backed off as follows: L is the stripper or under faller wire which is carried by arms j M projecting from the shaft N. O is the faller carried by arms P upon the shaft Q. It is held up when not in operation by the spring R', and is connected with the building apparatus in a manner that will now be described. Z2 is an arm projecting from the shaft Q to which is hinged the L shaped lever T which vibrates upon the shaft U which has its bearing on the carriage. One end of this lever carries a pin c which rests upon the surface of the former V as the carriage takes in and passes beneath it as seen in Figs. 2 and 5 as the carriage takes out. The former V at its outerv extremity bends at an acute angle as seen at W Figs. Q and 5. d is a latch or switch pivoted to the former at the point e which is raised by the pin c upon the lever T as the carriage reaches the end of its stretch. This latch is seen up in Fig. 5. X are bearings rising from the floor of the machine to which is hinged the former V by the long rods or bars f so as to permit V to rise and fall freely. This up and down motion of the former is effected in the following manner: A is a metallic plate sliding freely in mortises in the post B. This plate has two inclines gtupon which rest the rods f which carry the former V. If now the bar A be moved longitudinally in one direction or the other, the former will be raised or lowered. This motion of the bar A is produced as follows. L is a nut (Figs. l and 2) attached to the outer end of this bar into which works the screw C which runs in stationary bearings and carries at its extremity the ratchet wheel D. z" (Figs. 1, 2, and 4f) is a pawl carried by the arm k which rises from the shaft T. This shaft as already explained vibrates with each in and out motion of the carriage, and through the above connections turns the screw C a certain distance each time the carriage takes out, by which means the bar Aso A is moved longitudinally, and the inclined planes g sliding beneath the rods f" raise the former V as required to build the cop. m is an arm projecting from the shaft N which locks with a catch in the arm projecting from theshaft Q. The spring E attached to the arm n projecting from the shaft N tends constantly to revolve the latter and to raise the under faller wire'L, when the arm m is released from the catch o. 1?` is `an arm projecting from the shaft N. To this arm is hung by the adjustable connection g the lever F which is pivoted at the point r. Through this lever F passes the spindle t of the friction clutch F', the upper disk of which slides freely upon this spindle and is connected with the lever F by means of collars (Fig. 2) so that when the lever is raised by the depression of the under faller wire L and revolution of the shaft N, the clutchy is opened and the two disks revolved independently of each other. When however the lever F is permitted to yield to the action of its spring G the clutch is closed and its two parts revolve together. t is a pulley attached to the upperihalf of the clutchl and revolving `with it. Around this pulley passes the' cord H which isilattachedatboth ends u f to /as--they are turned bythe cord F. When the carriage takes out, the belt E runs upon the pulley H and the" spindles are driven by the cord E.

At such times it is evidentthat the friction clutch should be openedp and this is eifected in the following manner.

Theunder faller wire L is depressed in the l usual manner by the arms I which are suitably connected thereto and pass between the projections K from the front of thel roller beam, and `the shaft `Y is thus re-; volved until the arm m passes beneath the catch b and through the connections p g F `the clutch is `kept open. The pin c upon the lever `T having passed over the `end of theformer` V the shaft Q is re- `volved by the spring R and the catch b holds' the arm m fast. When the carriage reaches the end of its stretch, the pin` 6 comes in contact with the inclined WV up which it slides past the latch Z by` which4 means` the shaft Q is revolved and the arm m escapes from the catch As soon as this takes place,\the spring Ffthrows up the stripper L at the same instant the lever F descends, the `friction clutch `is closed andthe spindles through the cord H and i pulley `receive a slight backward motion which backs off the balance of the yarn,the

driving belt E having been previously` shippedonto the pulley F. The winding,

on may be accomplished by the motion of? the carriage 1n a manner analogous to that l above described, theextra cord H`be1ngi dispensed with, and the driving cord E being caused to perform the spinning as described when the carriage takes out and to perform the winding on as it takes in. Fig. 7 is a diagram for the purpose of illustrating this method of winding on. 1 is the driving pulley or twist pulley upon the head stock. 2 is a loose or carrying pulley upon the same shaft. 3, 4, and 5 are loose pulleys upon a common shaft upon the carriage. 7 and 8 4are loose pulleys upon a stud at the lower end of the machine. 6 is a pulley attached to the drum which drives the spindles. The pulley 3 is encircled by a friction band brake `which is operated by the faller and under faller in manner precisely similar to Vthat in which the friction clutch is operated. As the carria'geltales out the twist pulleyl drives the spindles and the spinningis performed, all the other pulleys eX-V cept G operating only as carrying pulleys. Zhen the carriage takes in, the pulley 3 is clamped fast and prevent-ed from turning the driving belt at the same instant being` so shifted that the pulley l becomes a loose or carrying pulley. The cord g fbeing clamped to the carriage is driven by it as it takes in, and the` winding on is hus accomplished by the motion of the cartiiage.

Some contrivance becomes necessary to give an equable surface mo-tion to the cop, driving, the winding on process, and this is accomplished in the following manner. The yarns on the way from the delivering roller pass beneath thefaller wire O and over the under faller L. If now the tension of the yarns becomes considerable theydepress the under faller and by means of the connection between it andthe friction clutch, the latter is opened or allowed to slip slightly until the under faller again yieldsto the action of the springs E and G and thus' the winding on is effected under an uniform tension, whatever may be the size of the cop.` y

Other parts of the machinery no-t immedi at-ely connected with my improvements it is deemed unnecessary to describe.

The extreme simplicity of the mechanism above described results from the use of the cone pullies for the purpose of imparting the varying motion to the carriage', The operation of these cones has been found to be most perfect, particularly where `the lower cone has been hung upon a weighted or spring lever. v

Operation: Commencing with the carriage as it begins to talle out, the belt E running upon the pulley Hand the belt Y being in the position seen in Fig. l, the carriage runs out with a slow motion and the spindles are .driven by the cord E upon the twist pulley D in the manner described, the friction 'clutch F having been opened by the depression of the counter faller wire L', which state of things is maintained by the arm Z which catches over the arm m as already eX- plained and as seen in Fig. 2. The pin c upon the lever T" having passed over the end of the former V', the faller Q is held up out of the way of the yarns asin Fig. 2, by the spring R assisted by the weight of the lever T. As the carriage nea-rs the end pf its stretch the incline n strikes the arm Z and shifts the belt E to the pulley F and the spindles are no longer driven by the twist pulley D which as before stated runs together with the pulley H loosely upon the shaft G. The next instant, by the rising of the pin c up the inclined plane VV, the arm m is loosed from the catch Z and the under faller L is thrown up; the friction clutch F closing just before the carriage has completed its outward motion, the spindles make a few retrograde revolutions and the balance of the yarn is backed off. The pin o has now ascended the inclined plane W and passed the latch cZ, and in so doing has depressed the faller wire o which is now in position to commence the building of the cop. The arm V upon the shaft T having during the last moments of the outward traverse passed between the levers VZ and A raising the point of the latter againstts spring 7e, is now in position to be operated Vupon by thelever A for the purpose of Ain with its fast motion, the clutch F remaining closed the spindles are driven by the cord I as already explained,r and should .the yarn, as the cop increases in size, become too tight, the under faller is depressed which opens the clutch and permits the disks to slip upon each other, and thus retard the lnotion of the spindles as required. The pin c upon the lever T rests upon t-he surface of the former V as the carriage takes in, by which means the motion of the faller is governed and the co-p is formed.

As it would not be safe to permit the carriage to arrive under the speed with which it takes in, before it reaches the head stock the lever Z strikes the arm U and shifts the belt Y into the position seen in Fig. l, and the motion of the carriage is eased off as it comes in. The under fallerr is then depressed and the friction clutch ope-ned by the passage of the arms I beneath the projections K, the arm m passing beneath the catch Z which has the instant before been depressed by the dropping ofy the pin o over the end of the former V. The incline m now strikes the pin p upon the belt shipper B and shifts the belt E onto the pulley H, and

be constantly stopped and reversed, while the original cost of construction'is greatly reduced.

Vhat I claim as my invention and desire to secure by Letters Patent, isfl. Driving the carriage in and outV by the continuous motion of the cone pulleys in combination with some method of automatically shifting the belt, for thepurpose of adapting the speed of the carriage to the requirements of the different parts of its traverse, by which means I am enabled to dispense wit-h the complicated mechanism heretofore adopted for the attainment of the same end.

2. I claim the pulleys F and H upon the shaft Gr arranged and operating substantially as described, bywhich a continuous motion in one direction is given to the shaft' tjr for the purpose of driving the carriage, and .an intermittent motion to the twist pulley D, when the winding o-n is accomplished by mechanism. independent of the motion of the twist pulley.

'3. I claim the friction pulley F or its equivalent lconstructed and operating substantially as described, n combination with an efficient method of regulating the speed of the spindles by the tension of the yarns in the manner set forth, by which means I dispense with the complicated machinery heretofore made use of to regulate the winding on, and am enabled to run my machine at a speed far exceeding that which can be attained where the motions of heavy cogged gearing are to be constantly reversed.
