I wish it to be understood however, that while I have shown a particular type of bobbin, any other equivalent thread-carrier or wou'iid package may be employed in connection with the present invention,
In order to supply the shuttle with my improved retainer clip, it is necessary to alter the latter slightly, and as will be observed from the drawing, the shuttle is formed in its upper and lower faces with elongated grooves 1 opening into the aforesaid recess R. These grooves are undercut as indicated at 2 to accommodate portions of the hereinafter described retainer. The shuttle is further countergiooved as at 3, leaving a relatively thin web 4: as a partition between the upper and lower countergrooves.
Although the improved retainer could be constructed otherwise, it is preferably com posed of two symmetrical half lsections 5 which are substantially U-shaped in general outline. Each section comprises upper and lower attaching arms 6 which are bent as indicated at 7 to accommodate a portion of the head of the bobbin as seen more clearly in Fig. 1. The attaching arms are bent together at their free ends as indicated at 8 and the extremities thereof are inturned as at 9.
The bight portions of the retainer sections are bent into arcuate formation'as at 10 to provide opposed jaws for reception in the aforesaid grooves in the bobbin head. For the purpose of connecting the two wire sections together, I employ a pair of comparatively small coiled springs 11 which, as seen in Fig. 5, receive the inturned ends 9 of the sections. These springs 11 serve a very important additional function to appear later.
In order to secure the retainer in place, I preferably employ a pair of face plates l2 which are shaped to lit into the aforesaid elongated grooves 1. As seen more clearly from Fig. 2, these plates are provided with integral projections 13 on their inner faces which are adapted to be disposed in the aforesaid countergrooves-3. rI`he projections and plates are formed with alined holes, one of which is screw-threaded to receive the threaded end of a fastening screw or bolt 14.
It will be observed more clearly from Fig. 2 that the aforesaid springs 11 bear at one end against the projections 13. It is also to be noted that the so-called jaws 10 are spaced from the adjacent end of the recess it to permit a portion of the head of the bobbin to be disposed between said end and jaws. In this connection, it will be observed that the provision of the springs will permit the jaws to be moved towards and from said end of the recess to accommodate different sized bobbins. It is in this way that the aforesaid self-adjusting connection is had. Attention is also directed to the fact that the face plates 12 do not bear on the arms of the retainer. Hence, these retainers are freely slidable against the tension of the springs. As before intimated, the springs serve the additional function of shock absorbers for the bobbin.
While the foregoing, description will doubtless suffice to enable a clear understanding of the construction and method of application of the invention, it is deemed advisable to set forth in a more precise manner, the action of the important shock-ab-v sorbing means. To this end, it will be seen that as the springs are always under tension, they tend to maintain the head of the bobbin in very close spaced relation and sometimes in contact with the adjacent end of the recess of the shuttle. Fig. 1 and assuming that the shuttle has been struck by the picker stick to drive itv in a direction from left to right, it will be seen that the spring means will maintain the bobbin in the aforesaid relation, and the shuttle and bobbin will move instantaneously as a unit, this being unobjectionable, as they bobbin then has no tendency to be -driven out of the windings of thread. When the shutt-le reaches the remote end of the guide track and is checked by the other pickerl stick, it is obvious that the shuttle will move slightly with respect to the then inert bobbin, thereby absorbing the shock which would otherwise have a tendency to cause the endmost windings o-f thread to leavethe other windings on the bobbin by momentum.
While the specific structure shown and described is the preferred embodiment of the invention, it is to be understood that changes in shape, size, and arrangement of parts may be resorted to within the scope of the adjoined claims.
I claim:
1. A device of the class described comprising a recessed shuttle, bobbiirembracing jaws in the recess thereof, and shock-absorbing means mounting said jaws within said recess.
2. A device of the class described comprising a recessed shuttle, relatively movable bobbin-embracing jaws in the recess thereof, and combined means for yieldably forcing said jaws toward each other and for yieldably mounting said jaws in the recess for slight movement longitudinally of the shuttle.
3. A device of the class described comprising a recessed shuttle, bobbin-einbracing aws in the recess thereof provided with carrying arms slida-bly engaged with said shuttle, and spring means connected with Referring to.
said arnis and engaged with a part of said shuttle for resisting the sliding movement of the jaws with respect to the shuttle.
4. A device of the class described comprising a. recessed shuttle, a bobbin-retainer within said shuttle formed of two substantially U-shaped sections, the bight portions of said sections being shaped for reception in a groove in the head of a bobbin, the free end portions of said sections being slidably mounted in the bobbin, and coiled springs engaged with said free end portions of said sections to permit yielding thereof longitudinally of the shuttle.
5. A bobbin retainer comprising jaws for engaging the head of the bobbin, attaching arms for said jaws, and a coiled spring for connecting the ends of said attaching arms together.
6. A bobbin retainer formed from wire, said retainer comprising jaws for reception in the groove in the head of a bob-bin, and a. pair of attaching arms to slidably engage a portion of a shuttle, the extremities of said attaching arms being inturned, and a coiled spring in which said inturned ends are received.
7. A bobbin retainer comprising a pair of substantially U-shaped sections, the bight portions of each section being shaped for reception in a groove in the head of a bobbin7 the free end portions of the arms of said sections being bent together and the eXtremities being directed inwardly, and coiled springs Jfor reception of said inwardly directed ends.
8. A bobbin retainer comprising jaws for engaging the head of a. bobbin, and arms Jfor attaching said jaws to a shuttle, ai coiled spring for connecting said arms together, and a face for reception in a groove in a shuttle, said plate being provided with inwardly directed projections against which one end of the aforesaid spring bears.
In testimony whereof I have hereunto affixed my signature.
