TAFE OR BRAID XVINDER.

Application filed November This invention relates to'textile machinery and has particular reference to tape or braid winding machines.

Among the objects of this invention is to provide a tape or braid winding machine which is of particularly simple construction so as to be relatively inexpensive to manufacture and to be wholly reliablein operation, said machine including various novel features such as, for instance, means for facilitating the forming of a skein of braid or tape which is tightly wound and in such manner as to be retained in good condition in shipment, and means for automatically stopping the machine after such skein has been completed.

Another object of this invention is to provide a tape winding machine or the like which is of novel mechanical construction to facilitate the rapid winding of tape or the like into a skein and with the desirable degree of uniformity and tightness to secure the maximum uniformity of appearance, such machine comprising a minimum number of moving parts which are soarranged with respect to each other as to secure the maximum reliability.

With the foregoing and other objects in View the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is bad to the accompanying drawings in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a plan view of the machine showing the same at the moment of beginning a new winding in the course of the formation of a skein of tape.

Referring now more specifically to the drawings, 1 show my machine as comprising a reel including a plurality of spaced parallel arms 12 which are supported in any suitable manner as by means of a bar or frame 13 which is rotatable about a shaft 1 1. The arms of the reel are secured to said frame in any suitable manner as by means of anchor members 15, said anchor members boing bolted to the frame through slots 16 so as to be movable along said frame for ad justment of said arms toward or away from each other according to the size of the skein to be formed. The shaft 14 constitutes the main drive shaft of the device and is journaled in bearings 17 and 18 which are fixed upon the frame 19 of the machine. Journaled freely on said drive shaft is a pulley I 21,) which has a groove to receive a belt 21, a disk being provided to have frictional engagement with said pulley as by means ofa friction gasket 23 inserted directly therebetween. The disk 22 has a hub 2% which has connection with the drive shaft by means of a spline A spring 26 mounted upon said shaft is provided for actuating the disk 22 into frictional engagement with the gasket 23 while the spline 525 permits of suitable movement of said friction disk along the shaft for this purpose; Suitable drive means such as a worm 27 is fixed rigidly to the drive shaft, and preferably for the sake of siinplicity of construction, the spring 26 has direct abutment relation against said worm at one end thereof and at the other against the hub it is clear that when the belt 21 operates as, for instance, in the direction of arrow a, that a torque will be transmitted through the gasket 23 and hub 24 and thence to the worm. 27; the reel being mounted upon the drive shaft is rotated directly thereby, while other parts in the operating mechanism that will be described hereinafter are actuated from the worm The reel may assume such form as is feasible with the main idea. of this invention as will be indicated hereinafter. I have found it desirable to provide the arms 12 with grooves 28 extending along the outer surfaces of said arms remote from each other. the groove being deepened as shown at at the free end of each of said arms, the side portions said arms about said groove at 29 beingbent somewhat toward each other, thus tor-mine a reliable spring -lan1 It will now be seen that a cord 3 can be readily placed in position in said groove. one end thereof being clamped at 29 and the other by any suitable spring clamp 31 which is positioned upon the tired end of each of said arms. Before the tape T is to be wound upon the reel cords are placed in position as described, and then. the skein is formed and after being completed, the strings may be tied about the skein before removing the same from said arms. Inasmuch as these cords are positioned at the ends of the slzein, they provide a reliable fastening therefor.

The tape is wound on the reel at one portion thereof forming a winding of a certain number of turns and then the tape is supplied to another portion of the reel pref erably immediately adjacent to the winding last formed and a new winding is formed thereon, continuing in this manner until the slrein is completed. A guide isso arranged as to be movable relatively to said reel. Preferably the guide is mounted upon a shifter bar 38 which carries a rack 34 and is preferably cut directly into said bar. a cam being; operatire to more said bar whenever a new winding of tape is to be formed upon the reel. It rill be understood that the vitch of a tooth of said rack will be equal to the width of the tape. Likewise that tae pitch of the cam will be equal to the width of the tape so that every time the bar shifts the guide will be moved jus' enough to feed the tape to a portion unmedn ately adjacent .ie vnnding last formed. The cam 35 is for the sake of sin'iplieity of construction supported upon the shaft 14rso as to be rotatable about the axis of the reel. said 1, being; secured to the frame 13 of the reel as by means of screws 36 and a sup porting bar 2-}? which is fastened to the hub 38 of the reel. It follows consequently that he cam makes a COIIlPlGlLt-B rotation every ees-e95 tape have been formed upon the reel at one particular portion thereof, it being then desirable to begin a new winding as shown in Fig. l. The means for mounting the ba in said manner and for causing such movement of the bar transversely to the axis of the am 35 may assume any suitable form. However, I prefer to use a worm wheel 89 which has meshing; engagement with the worm 27 and carries a suitable actuatin member or cam 40 which co-operates with follower 4-1 to cause a transverse movement of the shifter bar as aforesaid every time that the worm wheel completes revolution. it clear that the gear ratio as between th worm and the worm wheel will control as to the number of turns of tape formed upon the wheel before a new winding is put on, and that the bar 33 moves in constant parallelism to the axis of the cam 35.

The worm wheel 89 has a hub 42 which is secured to a shaft 4; journaled in a bear ing at. a collar being used to retain the shaft in its proper place within the bearing. The can]. 4.0 mounted rigidly upon the hub 42 and has working contact along a comparati ely steep surface 46 on the foll lower It is obvious that actuation of the follower 4- 1. by the cam must occur through a relatively small angular moremeut of the worm, wheel as determined by the size of one of the teeth thereon inasmuch as rotation of the worm wheel through such angular dista ce is caused by one complete rotation of the worm. The shifter oar 33 movable in any suitable manner toward or away from the cam 35 when the follower is actuated by the. cam. Pr. u'ably, h wever, for the sake of simplicity of construction. a bracket 4'? is pro vi ded wlich is arranged to l'Oi'li upon a hearing or shaft .28 which is mounted within the bearing supports l-t'l upon the ame or". the machine. The bra :ket 4.7 includes a guide or housin portion for the shifter bar and an an ary stationa y supporting member or bar 50 acts as rei orcenient for the shifter bar. A cover plate 51 secured guide oortion ii A by n runs of cwsor the li e to retain the shift .1; bar in liable slidable position. The. lower end of. bracket 4' is provider with a holder poron. within which the follower ll is i lon 'itudinally and generally transof the reel. The follower s cooperation therein to prevent. The screw is follower a nins e holder til) er is thus adjustable to suit any operating conditions and to obtain a precise adjustment for maximum efliciency of operation.

(lo-operating with the cam 40 is a spring 56 which is secured at one end to the frame of the machine and at the other end to a portion of the bracket 47- so as to be operative to tilt or rock the bracket toward vertical position as shown in Fig. l and with the rack of the shifter bar out of engagement with the cam 35. hen this occurs, the working face 46 on the follower will be positioned directly in the path of the cam 40 so as to be readily actuated thereby. A stop 57 is secured to the frame of the machine and operative to limit the tilting movement of the bracket under actuation of the spring 56. i

The guide member a9 is provided with automatic or resilient means to engage the shifter bar 33 and retain the same and consequently the guide 32 in relatively fixed position while tape is being wound upon the reel at one portion thereof. This means takes preferably the form of a spring 58 while the shifter bar is provided with a series of grooves or recesses 59 along an edge surface thereof opposite to the rack 34, the pitch of said grooves being equal to the pitch of the rack teeth. Consequently when the cam 35 operates to move the bar longitudinally for starting a new winding of tape on the reel, the spring 58 snaps into a new notch or groove and is eflective for retaining the bar against unintended movement until the winding at the particular portion of the reel is completed. Moreover, assuming that the entire skein on the reel has been wound and a new; skein is about to be begun, the bar 33 is readily moved through its supporting member or guide 49 back into initial position and against the force of the spring 58 which will then slip in and out of the series of notches. To facilitate such manual movement or actuation of the bar, a handle which may take the form of an upright rod 60 is provided secured rigidly to the shifter bar.

My invention includes novel means for automatically stopping the machine after a skein has been completed. However, conforming to my object for providing a ma chine of maximum simplicity, I have devised a novel arrangement of parts having particularly simple and easy co-cperation with the other and main members of the machine. For bringing the machine automatically to a stop, I use a bar 61 which is movable or tiltable about the shaft 48 as an axis and is provided with a cam surface 62 to wedge or engage with the projection 63 which is formed integrally on the hub .24 of the disk 22. While the machine is operating in its normal manner, the bar 61 is preferably positioned in spaced relation to the hub 24;. However, when the machine is to be stopped, said bar or lever drops, thus permitting the cam surface ($2 to engage or wedge against a projection 63, and inasmuch as the direction of rotation of the operating mechanism is as indicated by arrow a, it is clear that the machine will in'imediately be brought to a stop, the clutch said locking mechanism including a trip I member which is arranged to be actuated by the shifter bar 33 after the same has moved outwardly to its predetermined position of motion. lvlore specifically, a bell crank 63* is provided which is tiltable about a pin or screw 64 while the hub 65 of the lever 61 is provided with a projecting portion 66 which is arranged to lock behind an arm 67 of the bell crank as is clearly shown in Fig. 6. A spring 68 is operative to throw the bell crank into normal locking engagement with the lever 61. The bell crank includes a transversely extending arm or member 69 while the shifter bar 33 has a strike member 70 secured thereto and having an inclined face 71 so that when the same strikes the arm 69 of the bell crank, said arm will be depressed and the locking portion 67 of the bell crank, raised, thus releasing the lever 61 and permitting the same to drop by reason of its own weight. Said lever may be provided with a weight orhandle 72 at the free end thereof to insure a reliable action of the lever in this respect.

The operation of the machine so far as the locking mechanism is concerned will now hebriefly described as follows: Assuming that the locking mechanism has been actuated and is in ope ation to stop the machine, if it should be desired to again start the machine, it is merely necessary to grasp the handle portion 72 and raise the same to a predetermined extent. The locking portion 6% of the lever will then be operative to pass beneath the adjacent portion of the bell crank and finally the spring 68 will tilt the bell crank into locking engagement with the lever. lVhen this occurs the machine is in position to be started. Assuming now that a skein is being wound upon the reel. and the guide 32 and consequently the shifter bar 33 is moving constantly toward the free end of the reel, the arm 70 is moving in that direction likewise and finally comes into abutment relation with the bell crank and due to the steepness of the surfaces will t ll the same the desired amount within the space of a movement equal to he pitch the tooth on the rack the lever 61 to be released in the escribed hereinbetore and the mastopped. specific arrangement has been described, it is to be understood changes n ay be made within scope or his invention. t will be understood parti ularly that certain features of the invcnti n are applicable for use in connection with a machine that is constructcd procure generally a relative movement between a guide and reel regardless of how such movement may be obtained. liurthermore, the rack S t may assume various terms or shapes. the teetxi, however, beessential in o'der to secure the inter nxittent or periodic movement for the sake of obtaining a relati "e movement as between the guide and the reel. Furthermore, it will be understood that as between the 85 and the s.."' bar 2-33, various arrangements are feasible which are operative to secure a re Ive movement of these mem hers into meshing engagement with each other for intermittent actuation of the bar. Furthermore, the term cam as regards the carused herein in the broad sense to indicate any means which may be used to actuate the SlllI tQY bar. Likewise the n'icans for obtaining relative movement as between the shifter bar and said cam may take various specific forms such as will be readily understood by those skilled in the mecaanical art.

in the employment of this machine for the winding or coiling of ribbon or other species of tapes upon cards or the like, it is customary to simply lay or otherwise place and hold temporarily a card upon or against the arms ol the reel so that by the operation at the machine as fully explained above, the conuuodity wound upon will be rolled or the card until a sulllcient amount thereof wil. be so rolled. The card will then be removed and another one put in place for similar treatment.
