19 Claims.

This invention relates to textile and other machines provided with one or more yarn or strand receiving spools, bobbins, tubes, or other similar devices, and more particularly concerns the means for mounting and operating such yarn or strand receiving devices.

Textile machines, such as certain yarn winding and twisting machines of the type manufactured and sold by the U. S. Textile Machine Company, of Scranton, Pennsylvania, ar provided with one or more decks ofsimilar yarn winding and twisting units, each of which units comprises means for mounting and rotating the spools, or other similar devices, on which the yarn is wound. The spool mounting and rotation means of such units, are all alike, and are arranged so that the yarn receiving spools can be mounted in the machine, subjected to the yarn receiving operation, and then removed from the machine. The modernization of such machines, to increase their output capacity, has been found to involve various problems. For example, it has been found that when the operating or rotating speed of the yarn receiving spools is increased beyond a certain point, the spools develop a wobbling action of such magnitude that the frictional driving connection between the spools and the spool driving means is interrupted in sporadic manner. This detrimentally affects the uniformity of the yarn winding arrangement and action. Then too, increase in output capacity of these machines necessitates the inclusion of certain desirable labor and time saving features, such as spool mounting means arranged to permit quicker and easier insertion and removal of the spools, means operative to permit positioning of the spools so as to facilitate the work of the machine operator in overcoming the difficulties resulting from yarn breakage, etc., and means permitting the insertion of spools of different sizes or lengths so as to increase the usefulness of the machine.

One object of my invention is to provide a novel spool mounting device that can be readily embodied in machines of the referred to type and which solves the indicated modernization problems of such machines.

Another object is to provide such a device which has certain structural and functional features of advantage over the similar devices of the prior art.

A further object is to provide such a device which embodies a novel lengthwise extensible multi-section member which is rotatably mounted in such manner that rotational movement of the member will efiect axial shifting of a pair of spool-end supporting elements, toward and from each other, so as to hold or release spools of the same or different lengths.

An additional object is to provide such a device in which the spool-end supporting elements each have combined therewith a freely rotatable roller arranged so that the respectively combined elements and rollers are independently and limitedly movable in parallel planes, and the rollers may contactingly engage frictional spool drive means, individually or simultaneously, thereby to maintain constant spool driving connection irrespective of any wobbling of the spool during high speed operation of the latter.

It is also an object to provide such a device having novel latch means arranged to releasably maintain the said lengthwise extensible multi-section member in one of a plurality of selective rotational positions, and novel resilient means arranged to urge axial movement of one the member sections relative to the other.

Another object is to provide such a device which comprises a base, a sleeve fixedly mounted on the base and provided with a spiral slot, a tubular member rotatably mounted in said sleeve and provided with a longitudinal slot, a rod-like element having a section thereof slidably arranged within the tubular member, a pin secured to the side of said section of the rod-like element in such manner as to project through the longitudinal slot of the tubular member and the spiral cam slot of the sleeve, an arm secured to the tubular member, an arm secured to the rod-like element, and spool-end supporting means on each of said arms.

Other objects are, to provide such a device in which said pin is' of determined lesser diameter than the width of the longitudinal slot of the tubular member, so as to afford limited turning movement of the tubular member relative to the rod-like element; in which a spiral spring is arranged within the tubular member so as to urge sliding movement of the rod-like element in one direction; andin which a latch is arranged to releasably maintain the tubular member in one of a plurality of selective rotational positions.

With these and other objects in view, which will become more apparent from the following detailed description of one practical and illustrative form of the improvements shown in the accompanying drawings, the invention comprises the novel device, elements ieatures of construction and arrangement of parts in cooperative relationship, as more particularly defined by the hereto appended claims.

Fig. 8 is a partial elevational and partial sectional view of certain parts of the device seen by looking in the direction of the arrow 8 in Fig. 2.

As previously indicated, the device of my invention may be embodied in a yarn winding machine, or some other machine, of the well-known type in which one or more yarn or strand receiving spools, bobbins, tubes, or other similar means, are arranged to be mounted and operated so as to have yarns or other strands wound thereon. Machines of this type are provided with such usual parts shown in the drawings as a frame member I and spool operating or rotating means 2, for properly mounting and operating a conventional spool unit, and it is to be understood that my device is designed so that it can be substituted in such machines for said units, in a manner requiring no changes in the construction and operation of the machine. In the present instance, the spool operating or rotating means comprises a pair of similar drive wheels 2, that are fixedly secured to a power driven shaft 2 of the machine.

The form of my invention illustrated in the drawings generally comprises a bracket or base 3 provided with two similar integrally formed pinch-binding clamps 4 and a bearing 5; a separate sleeve 5 provided with a cam slot I; a lengthwise extensible multi-section member generally indicated by the numeral 8; a pair of similar freely rotatable oppositely arranged members generally indicated by the numeral 9, that are carried by arms I and II in such manner as to .function as rotatable supports for a standard or conventional type spool I2; and latch means generally indicated by the numeral I3.

The bracket or base 3 is secured to the frame member I by suitable means, such as by stud screws I4, and the sleeve is held in fixed adjusted position by the pinch-binding clamps 4-.

As more particularly illustrated in Fig. 5, the lengthwise extensible multi-section member 8 comprises a tubular member I5 having a longitudinally extending slot I6, and a rod-like element comprising three integral parts of circular cross-section, each of which is of a different diameter and respectively marked I1, Fl and IT. The parts I'I and I'l of the rod element are telescopically arranged in the tubular member I5 so as to be axially shiftable or slidable therein, and the part I'I is of such diameter as to have an easy sliding fit along the inner surface of the tube I5. The outer surface of the tube I5 is of such diameter as to have an easy rotating fit within the sleeve 6, and the bearing 5 of the basemember 3. Fixedly secured within the tube I5, by press fit, or otherwise, is a bushing I8. A spiral compression spring I9 is mounted in tensioned condition on the rod element part II between the bushing I8 and a freely rotatable adjusting nut Il, which is in threaded engagement with a threaded end portion of the rod element part I'l as clearly shown. Secured to the rod element part Il so as to extend from the outer surface thereof, is a Stud screw or pin 20, arranged so as to project through the longitudinal slot I6 of the tubular member I5 and the cam slot 1 of the sleeve 6. It is to be particularly noted that the pin 20 is of lesser diameter than the width of the longitudinal slot I6. This provides for a certain amount of play, or rotary movement between the tubular member I5 and the rod element comprising integral parts IT, H and Il and consequently permits the arms Ill and I I and the members 9 secured thereto, to independently move in parallel planes. In other words, this arrangement permits the members 9, and therefore the spool ends in engagement therewith, to independently move in vertical direction, to a limited extent, during the time that the members 9 and drive wheels 2 are in driving association. The importance of this feature will become apparent from the later description of the operation of my device.

As more particularly shown in Fig. 6, each of the members 9 comprises a freely rotatable, double ball bearing drive head of standard construction, which is rotatably mounted on a short shaft 2|, having a threaded end portion extending through a side section of the respective arm It] or I I with which it is associated.

In each instance, the shaft 2| is secured in fixed position to its respective arm, by a nut 22, and a split lock washer 23 is interposed between the nut 22 and the arm to assure retention of the nut in locked position. Centrally secured to the inner rigid side wall of each of the freely rotatable drive heads, is a shouldered stud screw 24, the head of which is of such length and diameter as to snugly but easily fit into the outer ends of the bore of the spool I2. A split lock washer 24 is interposed in each instance between the stud screw shoulder and the said rigid inner side wall of the drive head, to assure retention of the stud screw 24 in position. In order that the freely rotatable members 9 may not only support, but also have driving engagement with the ends of the spool I2, a gasket 25 of relatively soft rubber or the like, is fixedly secured in an indentation formed in the inner rigid side wall section of each of the drive heads, in such manner that one of the flat side surfaces of the gasket 25 will contactingly engage and will press against the outer flat surface of the spool end or flange IZ when the spool I2 is properly mounted on the members 9. Similarly, the peripheral surface section of the drive heads is formed of a material, such as rubber or the like, providing good frictional contact, so as to assure good frictional driving connection between the members 9 and the drive wheels '2 of the machine.

The rear end of the arm I is provided with an integral pinch-binding clamp section II! which is adapted to be fixedly secured in selective position along the length of the rod element part ll. The rear end of the arm II is similarly provided with an integral pinch-binding clamp section I I adapted to be fixedly secured to the tubular member I5, between the bearing and one of the pinch-binding clamps 4 of the base member 3, as clearly shown in Fig. 5. The arms I0 and II are consequently alignedly secured in opposed adjusta'bly spaced relation to the parts I5 and I I of the lengthwise extensible member 8, in such manner that these parts are rotatable in unison about the center of the member 8, as indicated in Fig. 4. When the member 8 and arms II] and II have been unitedly rotated so as to occupy the position indicated by the dct-and-dash lines 9 in Fig. 4, the spool I2 is supported by the freely rotatable members 9-9 in its operating position, and the members 99 are in driving connection with the wheels 2* of the drive means 2 of the machine.

The latch means I3 is provided to releasably maintain the unitary structure comprising the arms I0 and II, members 9, and the lengthwise extensible element 8, in certain of the positions indicated in full and in dot-and-dash lines in Fig. 4. The latch means I3 comprises a latch arm 21, which is rockably secured to the outer side of arm II, by means of a stud screw 25, the rear end of which latch arm 21 is shaped to form a hook-like section 21 adapted to cooperate with two latch elements 28 and 29, integrally formed on the outer portion of the bearing 5. A spiral spring wire 3a is wound about the shank of the stud screw 26 (see Fig. 7), one end of which spring wire is anchored in an aperture extending through the side of arm II and the other end of which is turned about the latch arm 21 in such manner that the latch arm will be constantly urged by the spring wire 30 to effect engagement of the latch hook 2'! with the latch elements 28 and 29 on the bearing 5. Fixedly secured to the bearing 5 is a stud 3| directly in back of the latch hook section 21 which stud 3I functions as a safety lock element to prevent unintentional rearward rotational movement of the unitary structure comprising the arms In and I I, member 8 and members 9, without first operating or depressing the forward end of the latch arm 21.

Operation Referring more particularly to Figs. 1 to 5 inclusive, the device of my invention is operated substantially as follows:

The forward end of the latch arm 21 is depressed so as to disengage the hook-like section 2! thereof from the particular latch element 28 or 29 with which it is engaged, and this action will release the unitary structure comprising arms I!) and I I, members 9 and lengthwise extensible element 8, for turning or rotary movement about the longitudinal axis of the latter.

Assuming that the spool I2 has just completed its rotational yarn receiving action to form a completed yarn package, and the members 9 are still in engagement with the drive wheels 2 then the forward end of the latch arm 21 is depressed and upward and rearward rotational swinging movement of the arms I0 and II can be carried out from their position indicated by the dot-anddash representation thereof marked 1! in Fig. 4, to either the inoperative full line position thereof as shown in Fig. 4, or the inoperative dot-anddash position thereof marked I in Fig. 4. R0- tational movement of the arms I0 and II to the full line position shown in Fig. 4, will result in continued engagement of the members 9 and spool I2 as shown in Figs. 2, 3 and 6. However, as the arms I0 and II are rotationally moved upwardly and rearwardly, from their full line position of Fig. 4 to the dot-and-dash line position I, the extensible member 8 will be elongated, i. e., the rod element comprising the parts I1, 11* and I'l will move to the right as seen in Fig. 5, thereby causing compression of spring I9 and moving the arm I0 laterally away from the arm II This elongating action of the member 8 is caused by travel of the pin 20 to the right, between and along the cam edges of the cam slot 7. Movement of the pin 20 will also take place in the longitudinal slot I6 of the tubular member I5, so that the arms I0 and I I will be maintained in parallel aligned relation, except to the limited extent of the previously referred to play, or spacing, existing between the pin 20 and side edges of the slot I6. The said lateral separating movement of the arm II), from the arm Ii, will cause a corresponding separating movement of the members 9. When the position is reached that is indicated by the dot-and-dash lines I, in Fig. 4, the arms I0 and II, and consequently the members 9, will have become separated to an extent making it possible to withdraw the spool l2 from the stud screws 24. That is to say, the free ends of the stud screws 24 will have become separated by a distance which is reater than the distance between the outer surfaces of the spool flanges I2 2 When this rotational position of the arms Iii and II has been reached, the latch arm 2! may be released so that the hook-like section 2'! thereof may engage under the latch element 29, to hold the various unitary parts in the said position indicated by the dot-and-dash lines I.

Having removed the filled spool I2 from between the stud screws 24, a new or empty spool can then be inserted therebetween, the forward end of the latch arm 2'! depressed, and the arms I0 and I I again swung to the position illustrated by the dot-and-dash lines 0 in Fig. 4:, thereby to cause contraction of the member 8 so that the spool will be engaged by the studs 24 and members 9 as shown in Fig. 6, and again establish driving connection of the elements 9 with the driving wheels 2 of the driving mechanism of the machine. The hook-like section 21 of the latch arm 21 will then rest on top of the latch element 28 formed on the bearing 5, as indicated in Fig. 4. During the contracting movement of the member 8, the compression spring I9 functions to pull the rod element com prising parts II, I'I and I7 to the left, so that the part I! will slide lengthwise within the tubular member I5, and any existent free play or spacing between the pin 20 and cam slot 1 will be taken up, or this play will cause the members 9 to be pressed more tightly against the spool flanges l2 by the spring action.

When it is desired to quickly move the spool I2 to an inoperative position, so as to permit the operator to repair a breakage in the yarn being wound on the spool, or for some other reason, it is merely necessary that the arms Ill and I! be moved upwardly a suilicient distance to cause the hook-like part 2'! of the latch arm 2i, to become engaged with the portion 28 of the bearing 5, as shown in full lines in Fig. 4. The drive heads of the members 9 will then be disengaged from the drive wheels 2 sufficiently to discontinue the driving action of the spool. Thereafter, that is when the yarn breakage has been repaired, the spool l2 may again be rotated as before by simply depressing the latch arm 21 and permitting the arms and II, together with all therewith associated parts, to drop to their former position indicated by the dot-and-dash lines 0 in Fig. 4.

As previously indicated, the pin 20 is of lesser diameter, by a determined amount, than the space between the longitudinal edges of the slot IS. The play afforded by this arrangement, between pin 20 and the said edges of the slot [6, permits limited relative rotary or turning movement of the rod element comprising integral parts [1, H and N and the tubular member l5. Consequently, the arms l0 and II, and the members 9 secured thereto, will have limited independent rotary or turning movement in parallel planes. This limited independent movement of the members 9 permits the spool l2 to carry out the characteristic wobbling action, which develops during high speed rotation or operation thereof, and at the same time assures that, during this action, the driving heads of the members 9 will be maintained in constant driving contact with the drive wheels 2 of the machine, either individually or simultaneously. This feature is highly important in effecting proper yarn winding action at high speed operation of the spool, since either one, or both of the members 9, will be in contact with the driving wheels 2 at all times, thereby providing smooth and uniform rotary operation of the spool l2.

When it is desired to set the device for receiving spools 12 that are of a different length, than the spool shown in the drawings, it is merely necessary to release the pinch-binding clamp Ill at the rear end of the arm 10, and slide the latter on the rod part [1, toward or away from the arm H, by the proper amount to accommodate the spool of different length. After this has been done, the pinch-binding clamp Ill is again applied so that the arm I0 is fixedly secured to the rod part I! at the new location or adjusted position.

Of course, the novel device and improvements herein specifically shown and described, can be changed and modified in various ways without departing from the invention disclosed, the scope of which is more particularly indicated by the hereto appended claims.
