SEPARATOR MECHANISM FOR RING-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 498,340, dated May 30, 1893.

Application filed February 10, 1893. Serial No- 461,733. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHANNING WHITAKER, a citizen of the United States, residing at Tyngsborough, in the county of Middlesex and State of Massachusetts, have invented acertain new and useful Improvement in Separator Mechanisms for Ring-Spinning Frames, of which the following is a specification, reference be ing had therein to the accompanying drawings.

The invention is an improvement in separator-mechanisms of the class in which the separators are applied to suitable supports that are carried by vertical rods, termed sepa-. rator-rods, having communicated thereto a vertical reciprocating movement resembling. that which is communicated to the liftingrods which support the ring-rail with its rings. The invention relates mainly to the means for imparting to the separator-rods and the parts which are supported thereby the vertical reciprocating movement aforesaid.

It relates also to the guides or stands by means of which the separator-rods are held and guided in proper vertical position.

The main object of theinvention is to provide a simple, inexpensive, andconvenient arrangement and construction'of parts for communicating movement to the separator-rods positively in both directions, which shall include a convenient means of eifecting the vertical shift or translation of the traverse of the separators that sometimes it is desired and necessary to make without altering the extent of such traverse, and which shall require-or consume very little of the power that is used for the purpose of actuating the ring frame to which it is applied.

Another object of the invention is to provide a stand of simple and strong construction which shall have capacity for enabling to be made all the adjustments ordinarily re-l I quired to be made in practice.

Another object of the invention is to pro-f vide for supporting the separator-rail on the separator-rods in such manner as that when desired the separators may be turned from their working position between the spindles to a retracted or backward inoperative posi{; tion, and at any time the separator-rail and drawings, and as is particularly pointed out and clearly defined in the claims at the close of this specification and forming a part hereof.

In the accompanying drawings, Figure 1 is a view in front elevation showing a portion of a ring-spinning frame with the preferred embodiment of my invention applied thereto. Fig. 2 is a view in vertical section on the line 2-2 of Fig. 1.

I In Figs. 1 and 2, 1 is the roller-beam, 2 the thread-board-diinged thereto as usual, 3 the finger-boardshinged as usual to the threadboard, athe yarn-guides secured to the finger-boards, 5 the yarns passing from the yarnguides 4. to the bobbins 6, through the travelers 7 on the rings 8 supported by the ringrail 9, 10 the spindles on which the bobbins" are mounted, 11 the spindle-rail, 12 the lower or guide-rail, 13 the lifting-rod for the ringrail, let the shoe or foot at the lower end of the said rod, 16 the cross-shaft arm carrying the stud or pin 15, the latter either acting diat 18 the crossshaft on which the said arm is secured, the said cross-shaft turning in bearings in brackets 19 (only one of which brackets is shown) and being caused to rock by usual means for the purpose of moving the ring-rail up and down.

All of the foregoing parts may be of any usual or preferred construction.

At 20 the separators are shown, and at 21 the rail on which the separators are mounted.

At 22 is shown one of the separator-rods by the upper ends of which the separator-rail 21 is supported, the said rod being held in up right position by a guide or guides 23.

In making provision for actuating the rod.

22 from the cross-shaft arm 16 simultaneously.

with theactuation of the ring-rail from the said arm, and in the same direction but through a traverse of less extent, and also positively in both directions, I contemplate employing various connections, differing among themselves in minor structural details, but all embodying thesame generaland i characteristic elements or features and prin-;

ciples. The first of the essential elements or} features is the collar 24, the said collar beingl slipped upon or applied to the separator-rod. Thesecond of the said essential elements or features is an appropriate securing or ad-} justing device by means of which the collarj 2-tis secured in place at an intermediate point in the length of the separator-rod.

In the drawings I have shown the collarv held in place by means of a clamping-screw 25, which is fitted to a threaded hole in the collar and takes bearing at its inner end; against theshaft. The third of these essen-l tialelements or features is a connecting-rod, one instance of which is the connecting-rod? 27 in Figs. 1, 2, 3, 4and 5, interposed between} the collar 24 and the cross-shaft arm 16, thel upper end, of the said connecting-rod being; pivotally or otherwise suitably connected or} engaged positively with the collar, and the} lower end of the connecting-rod being con-, nected likewise in a positive manner with the} cross-shaft arm 16 as bya stud or pin 30 onf the said arm at a point intermediate the axis-j on which the said arm turns and the point at which movement is communicated to thelitt. ing-rod for the purpose of actuatingthe ring-j rail. 1

The general considerations which lead to the employment of the foregoing features the following: The said connectionsare such asto cause the separator-rail and separators to rise and fall simultaneously with the ring: rail and rings, but through a traverse of less: extent, as is necessary in order that the separators may be maintained at all ti mes in proper position relative to the parts adjacent to which they are in the spinning-frame, the connect-, ing-rod swinging laterally in all arrangements in which it is connected pivotally with the; collar, to enable its lower end to follow the; curve of the arc in which the stud or pin 30 travels as the cross-shaft arm rises and falls.

By varying the point at which the collar 2t is fixed by the screw 25 to the separator-rod 22, the height of the separator-rail and separators in the spinning-frame may be varied as required, and, also, the traverse of the separators may be shifted or translated vertically without the extent of such traverse being changed.

It is found in practice, that cotton flyings continually collect upon the surface of the separatorrod, particularly when such surface is rough or oily. It results, when the bearings through which the separator-rod slides vertically have been too loosely fitted to the said rod in the first instance, and also when the said bearings have become too large through the wear incident to use, that the cotton fiyings which collect upon the surface of the rod pass in betweenv the rod and the said bearings, thereby clogging theopening between them, and this clogging, if not, relieved by the attendant, goes on increasing until the resistance due to it becomes so great as to overcome the tendency of the parts to fall of their own .weight after having been raised. l-Ieretofore, it has been customary to nearly counterbalance the weight of these partsand to depend upon the unbalanced portion of such weight to carry them down after being lifted, and it has resulted in practice that the parts would not descend as intended ,when the bearings became clogged, but would'remain for some time suspended, and then, perhaps as the result of a jar, go down suddenly with a jerk. If, at such times, through the too great flexibility of the separator-rail, some of the separators should strike against the ring-rail the regularity of, the winding-on of the yarn would be disturbed. Asa complete safeguard against the obj ectionableresults of such clogging, I make the movements of the separator-rod positive in both directions, as above mentioned, so that if, in consequence of clogging, the separator-rod should stick sufficiently to prevent the separators from descending because of the weight of the parts, the machinery will draw them down.

It has been proposed heretofore to make the movements of the separators positive in both directions in separator-mechanisms of the same structural type as that which isrepresented in the accompanying drawings, ,butin all known instances of this kind the construction adopted has been of such character as to prevent adjustment such as is required in order independently to shift or translate vertically the traverse of the separators. My present invention has as a special object ,to entwisting or rotation.

28, of the connecting-rod is forked or split,

the arms 2929, of the fork, receiving between them the collar 24, and the said arms being made to occupy positions at the front and rear sides respectively of the collar.

Screws 31, 31, are passed through the said arms and into the collar, to connect the con meeting-rod and collar, and also to serve as pivots on which the connecting-rod can turn as it swings with the cross-shaft arm.' The connecting-rod is symmetrical on each side of the axial line indicated in Fig. 3, and is of open construction, with the two sides 3232, thereof, bowed apart and separated to the extent which is necessary in order to provide against contact of the said sides with the parts which are located between them. The lower endof the connecting-rod is formed with a hole, 33, therethrough to receive the stud or pin, 30, projecting from the cross-shaft arm, 16, the said end being held-in place upon the said stud or pin, 30, by means of a split pin, 34, passed through a hole in the free end of stud 30 outside of the connecting-rod. The lower end of the separator-rod extends down between thetwo arms, 2929, of the forked upper end of the connecting-rod, and also between the two sides 3232 of the said connecting-rod, while the said sides are located at opposite sides of the lower guide, 23, for the separator-rod. The construction is such as to enable the lower end of the connectingrod to be pivoted to the cross-shaft arm at a point on the latter which is so located that the horizontal component of the movement of the pivotal stud or pin 30, as it swings in a circular arc, shall be bisected by the center, line of the separator-rod. I consider this the best arrangement. It results in maintaining, at all times, in the movement of the cross-shaft arm, the point at which force is transmitted from the cross-shaft arm to the separator-rod as nearly as possible in line with the separator-rod, and reduces to a minimum the side pressure and frictionof the separator-rod in itsguide's. Also, the line of the force transmitted to the separator-rod from the cross-shaft arm is located in the same vertical plane as the center line of the separator-rod, from which it results that there is no tendency to twist or rotate the separatorrod in its guides, and it is madeunnecessary to employ special devices to prevent such Further, in the case of the connecting-rod shown in Figs. 1 to 5 the force transmitted by means of the connectingrod is transmitted in a line passing through the axis of symmetry of the connecting-rod. This form of connecting-rod may be made very light because of the rigidity and strength secured by its structure.

A modified form of connecting-rod capable of securing similar results, but requiring to be made of somewhat heavier build in order to give it the necessary rigidity and strength is represented in Figs. 6 and 7. The difference' existing between this form and that which has been described is simply that in this form the connecting-rod is not made bilateral and symmetrical, when viewed in the position represented in Fig. 7, but is unilateral and unsymmetrical. Both forms are sym metrical when viewedin the position represented in Figs. 2 and 6. That part of the form of connecting-rod shown in Fig. '7, which is intermediate the ends thereof, is bowed sufficiently to provide against contact with the lower end of the separator-rod and the lower guide, 23. I

In the modification that is represented in Figs. 8, 9 and 10, the collar, 24, is provided with a rearwardly projecting pin, 35, on to which is fitted the upper end of the connecting-rod here designated by the numeral 271, the said end of the connecting-rod having a hole through which the pin, 35, passes, and theconnecting-rod being held in place upon the pin, 35, by a split pin, 36, which is passed througha hole in the end of the latter. The connecting-rod at its lower end is formed with a hole therethrough to receive the stud or pin 30'projecting from the cross-shaft arm, 16, the said lower end being held in place upon the said stud or pin by means of a split pin, 34, passing through a hole in the free end of the stud or pin outside of the connectingrod. In these figures I have shown the stud or pin formed separately from the cross-shaft arm and with a screw-threaded portion which is passed through a hole, 38, made transversely in the cross-shaft arm, 16. The said hole may be either plain, or screw-threaded as shown. On the stud or pin are placed nuts, 39, 39, fitting against the opposite sides of the cross shaft arm and serving to hold the stud or pin fixedlyin place. In this modification, in consequence of the'conneotion of the upper end of tion with the features already described as pertaining to this modification a directing guide which shall hold the separator-rod against being turned or rotated on its axis,

'while, at the same time, it shall leave the said separator-rod free to be moved up and down as required. A simple form of directingguide is that shown in Figs. 8, 9 and 10.- In these figures, the projecting-head or end of the screw, 25, by which the collar, 24, is clamped in place upon the separatorrod, passes into a vertical slot, 40, which is provided in the upright portion or web, 41, of the stand 410 carrying the guides 23-23, for the separator-rod. g

In all of the foregoing modifications, I have embodied a connecting-rod which ispivotally joined at its upper end toa collar on the separater-rod, and is similarly joined at its lower end to the cross-shaft arm. This mode of construction and connection provides for actu-, ating the separator-rods with a minimum of resistance due to friction resulting from the movements of the connecting devices relatively to and upon one another. In Figs. 11 and 12, I have shown a further modification bearing in certain particulars of form a slight resemblance to that which is presented in Figs. 8' and 9, but resembling those which are presented in Figs. 1 to 7 in, having the line of the force transmitted tof the separator-rod lying in the same vertical;

plane with the center line of the separatormeeting-rod, instead of having the lower end of the said connecting-rod pivoted to the said-j In Figs. 11 and 12, the connect-; ing-rod is designated 272, and the slot in the stud or pin.

said connecting-rod in which plays the stud} or pin on the cross-shaft arm 16 is marked 42. The upper end of the connecting-rod is joined to the collar at a point which is offset from the separator-rod, as in the case of the con-i struction represented in Figs. 8 and 9. Inasmuch as in this modification it is unnecessary for the connecting-rod to swing or vibrate lat-. erally as the cross-shaft arm moves up and down, the connecting-rod and collar may be. formed integrally, as shown, or otherwise? fixedly connected togetherso as to form either actually or practically one piece.

n the lower rail 12.

To hold the connecting-rod from vibrating or moving laterally, I apply thereto a guide, 43, which is fitted to the said rod at some point where it will not interfere with the mov: ing parts. In Figs. 11 and 12, I have shown the said guide as receiving the prolonged lower end of the rod below the slotted por-. tion, and as forming a part of a stand, which is held by bolts 45, 45, and the nuts 46, 46, to The said bolts and nuts may be, as shown, those which secure the stand 410 to the said rail 12. In this (3011- struction, inasmuch as the force by which the separator-rod is moved up and down is applied always in a line which is parallel with the axis of the separator-rod and. sometimes is identical therewith, there is no tendency to rotate the separator-rod in its bearings, and hence the directing guide of Figs. 8, 9 and 10, is omitted.

More or less work, in the shape of fitting and adjusting, ordinarily has to be performed in applying and adapting separator mechanisms to ring-frames. To economize labor,

trouble, and expenditure of time in this direction, I have devised an adjustable stand for the separator-rod which is so constructed as to admit of being changed and shifted in a manner to meet all of the requirements or:

dinarily encountered in practice, and .to enable a separator mechanism to be quickly applied in exactly the desired and proper position and relations. In Figs. 5, 6, 7 and 13, I have shown the details of the said adjustable stand. In the remaining figures of the drawings I have shown only an ordinary and simple form of stand, in order to avoid confusion and to secure simplicity in the said other figurest In Figs. 5, 6, and 7, (see more particularly Fig. 6) the stand is shown composed of the main portion, 41, which is provided with the guides 23-23 for the separatorrod and with the two separate brackets 411, 412. Two of such brackets are provided, in order to secure steadiness, but one alone may be employed. The said brackets 411, 412, are formed substantially L shaped, and through a horizontal slot 418 in the vertical part of each is passed the stem of a headed bolt, 413, which also passes through a vertical slot, 416, in the main portion, 41, the said bolt receiving on its threaded end a washer, 415, and a nut, 414,- for securing the bracket andthe main portion together. Thehorizontal part of each bracket 411 and 412 has formed therein a slot 417 extending lengthwise of the said horizontal part, that is, at a right angle to the direction of the slot 418, and through this slot is passed the stem of the headed bolt, 45, the said bolt receiving on its threaded end the washer, 47, and the nut, 46, by which each bracket is secured to its supporting rail 11 or 12. The slots 416, 417, and 418, permit of, the guides 23, 23, being given a range of adjustment universallyin all directions to theextent ofthe limits imposed by the lengths of the said slots.

I do not herein lay claim broadly toa link pivotally connected at its one end to the separator-rod and at its other end tothe crossshaft arm, nor to actuating mechanism for a separatonrod embodying such a link and also adjusting means whereby the position of the separator-rail and separators may be shifted Vertically, for these are claimed in my application for Letters Patent for improvements in separator-mechanisms for ring-spinning frames filed February 10, 1893, Serial.
