SHUTTLE tvrnnnn.

Application filed September 23, 1328.

T 0 all whom it may concern Be it known that 1, JOHN F. lllirorinLL, a citizen of the United States, residing at T0- peka, in the county of Shawnee and State of hiansas, have invented certain new and use ful Improvements in Shuttle lVinders, of which the following a specification.

This invention relates to improvements 'in shuttles, more particularly tatting shuttles, and to devices for winding threadtheieon, and consists of the novel features of construction and combinations of parts hereinafter described andset forth in the appended claims. The present application is asubstitute for my prior application Serial n 151,457, filed Feb. 28,1917.

The objects and advantages of the invention will appear from the following description taken in connection with tie accompanying drawings wherein one form of the invention is illustrated.

In the drawings Figure l is aside elevation of the winding device showing the shuttle mounted in operative position thereon;

Fig. 2 is a ,jfront View of the apparatus;

Fig. 3 s'truction of the outer end of the shuttle carrying shaft;

Fig. 4: is a fragmentary .view showing the construction ofthe shuttle; and

5 is a section taken on the line 55 of Fig. 4.

Referringmore in detail to the drawings, the winding? device is shown as comprising a Staff or post 10 having a hand grip 10 at its lower end and beingbifu-rcated at its upper end to provide strips or fingers 10, which latter are bent over to form suitable bearings 10. lilounted in these bearings and extending transversely of the or post 10 isa shaft 11, having a hand crank 11 on. one end thereof. lieyed or otherwise fixed to the shaft 11 intermediate the bearings 10 is a collar 11 adapted to engage the bearings 1O at its opposite ends and to thus prevent longitudinal displacement of said shaft. The shaft 11 at the end thereof opposite the hand crank 11 is adapted for engagement within a centrally disposed passage'prov'ided in the shuttle 12 so that'said shuttle may be revolved upon rotation ofthe Shaft. l

The shuttle comprises the usual wings or side plates 12*" these plates being secured together according to the present invention by means of two web like members 1.1 placed face to face and secured to the inner races of the wings 12 by means of suitable upstanding flanges 12 Each web is provided with a transverse groove or depression 12 which when the webs are assemblech provide a transverse passage of noncircular design in cross section, this passage opening exteriorly oi the shuttle on each side thereof through the apertures l2 provided in the wings or side plates 12, The webs are also provided at opposite ends with small apertures 12 through one orthe other or which the end oi the thread may be inserted and knotted prior to the commencement of the winding-operation The flanges 12 oi the webs may be welded tothe wings or side plates of the shuttle or vmay he secured thereto by means ofsoldcr, rivets, or in any other suitable manner.

The end of the shaft 11 which is adapted to receive the shuttle 12 is slightly reduced along diametrically opposite plane's, as shown at 112 so to render said shaftof substantially the same design in cross section as that of the tranverse passage in the shuttle. As a means for preventing accidental displac nent of the shuttle longitudinallv of the aft after the same has been positioned thereoin the engaging end of the shaft ire-splitlongitudinally as at 1?, the spreading tendency or". the two prongs thus formed servirm, to i rictionally maintain the shuttle at any desired point on the shaft.

Carried by the staff or post 10 by means of a lateral projection 13 is a thread. guide 13. The projection i is provided with a flanged portion 13 adapted to receive the portion 10 of the post 10 and is provided with a screw-threaded stud l3 which. can tends through the slot 10 of the post sc that, by means of the nut 13 on said stud said thread guide may be adjusted longitudinally of the post and secured in any desired position. From the outer end or the lateralprojection 13, the thread guide extends rearwardly thence upwardly and forwardly in a curved direction opposed to the direction of rotation of: the shuttle, and terminates in the path traversed by the V shuttle when the latter is revolved and at a point-intermediate the wings thereof and in close proximity to the latter. This curved portion of the thread guide lies in the same plane with the shuttle and is provided, near its opposite ends, with grooves 13 and l3 which are adapted to receive and guide the thread as the same is drawn from a spool and wound on the shuttle. A linger 13 is provided near the groove l3 and serves to maintain the thread in said groo e, while the finger 13 at the other end of the guide serves to maintain the thread within the groove 1.3 The

grooves

13 and 13 preferably formed in the guide by pressing, and the hump or projection 13*, formed near the end of the guide during the op eration of pressing the groove 13 therein, may serve to spread the ends or points of the shuttle wings as the latter approach the thread passing between the

grooves

13 and 13, thus permitting the thread to pass between said points without being gripped or otherwise disturbed by contact therewith;

However, this spreading of the wi es is not essential to the operation of the device and vin practice it may be found preferable to mount the thread guide slightly higher on the staff or post 10 than shown in the drawings, so that the end of the guide may pass freely between the shuttle wings without effecting any spreading thereof. it also be found preferable to form the thread guide as an integral part of the staff or post 10.

In operating the device, it is preferred to grip the portion 10 of the staff or post 10 and to hold the device in substantiall vertical position. The thread as it passes to the guide may, if desired, be held between the fingers and thumb of the hand in which the device is held, so that said thread may be wound on the shuttle with the requisite degree of tightness. In cutting away of the shaft 11 along diametrically opposite planes,

' as above described, shoulders 11 are formed,

tle withrespect to the thread guide.

these together constituting a stop which determines the operative position of the shut- As will be observed, the shuttle receiving end of the shaft ll is made longer than really necessary for the supporting of the shuttle in operative relation with respect to the thread guide, this being done in order that, should it be desired to unwind thread from the shuttle for any reason, the same may be moved outwardly adjacent the end of said shaft, as shown in dotted lines in Fig. 2 of the drawings, whereupon the thread may be readily and quickly 'unwound without interference of the thread guide. The engaging end of theshaft being split, as above described, makes it posing accidentally displaced longitudinally of the shaft during a winding or unwinding operationl The form ofthe thread guide and its position relative to the shuttle and the direction of rotation of the latter constitute important features of the present invention. As previously pointed out, the gu de lies 1n the plane of the shuttle and proyects rearwardlyv from its point of attachment to the post 10 and thence upwardly and forward ly in a curved path opposed to the direction of rotation of the shuttle. The end of the guide terminates between the shuttle wings and the

thread grooves

13 and 13 formed in said guide are disposed in alignment the wing tips as the shuttle is rotated. This is an important advantage. The guidei preferably mounted in a vertical plane which contains the points of contact between the wing tips and by pressing the thread receiving grooves in the guide, as previously described, the thread may be disposed in the immediate plane of the latter and not nearer one side of the shuttle than the other. This coupled with the other features of they con struction insures an even winding of the thread back and forth on the shuttle and prevents the thread rom piling up or accumulating in the center or to one side.

It will be obvious to those skilled in the art, that the present invention is susceptible of various changes, and modifications, and it is not, therefore, desired to limit the same to the particular construction and arrange;
