SAL R. LIBERTY, OF PAWTUCKET, RHODE ISLAND BOBBIN-HOLDER FOR SHUTTLES.
Specification of Letters Patent. Patnted Ian 11, 1919.
Application filed July 29, 1918. Serial N0. 247,224.
' bin-Holders for Shuttles; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled inthe art to which kit appertains to nia-ke and use the same.
My invention has for its object to provide extremely simple and inexpensive, yet highly eflicient, reliable and durable means for holding the bobbins of loom shuttles and the like in place upon the spindles and for releasing the bobbin automatically whenthe spindle is raised, the device being particularly well adapted for use upon looms employed in the weaving of duck and analogous fabrics, although it is not restricted to any particular type of shuttle.
lVith. the foregoing object in view, the 1nvention resides in the novel construction hereinafter fully described and claimed.
In Figure l of the accompanying drawing, a longitudinal section of a portion of a shuttle is shown, equipped with the present invention, the bobbin or spindle being in lowered or operative position.
Fig. 2 is a view similar to Fig. 1 showing the spindle and loobbin swung upwardly for removal of the latter.
Fig. 3 is a horizontal section on the plane indicated by the line 3 3 of'Fig. 1.
Fig. 4 isa vertical transverse section on the plane indicated by the line 4-4 of Fig. l showing the normal relation of parts.
Fig. 5 is a transverse section on the plane indicated by the line 5 5 of Fig. 2 illustrating the 'manner in which the bobbin4 holding arms are spread ywhen the spindle is raised.
In the drawing above briefly` described, the numeral 1 designates a common form of shuttle having the usual bobbinrecess 2 and spindle 3, the latter being pivotally mounted -at 4 for normal disposition inthe recess 2 and for Yswinging upwardly therefrom as seen inFig. 2 when the bobbin 5 is to be removed or applied. Heretofore, numerous arrangements have been employed for automatically kgripping the bobbin when the spindle is forced downwardly into the recess and for releasing said bobbin when the spin dle is raised, but the majority of these devices have been comparatively complicated and expensive. yet have given little satisfaction, often damaging the bobbin. The present invention however` aims to overcome these difficulties by the provision of an eX- tieinely simple and inexpensive arrangement for accomplishing the saine results as the devices mentioned. In attaining this end, I provide the construction described below.
A pair of yielding arms 6, preferably in the form of flat springs`constructed of a single'strip of metal, and disposed one on each side of the pivoted spindle end are provided, said arms being connected with said end for movement bodily/therewith This connection may be effected in any one of a number of ways, but I preferably )ass the pivot pin 4 of the spindle through t e arms and in addition use one or more rivets 7 passing through the pivoted end of the spindle and through'the arms in question. The free ends of the yielding arms 6 project into one end of ,therecess 2 and are provided with suitable bobbin holders 8 preferably formed by bending the ends of the arms inwardly as shown clearly in Fig. 3. A pair of downwardly diverging release arms 9 have their upper ends pivoted at l0 upon a common aXis to a metal plate ll secured to one end wall of the recess 2, the lower ends of said arms being tapered and located betweeivthe spring arms 6 and the position of F ig.` 2, said spindle will engage.
the inner edges of the release arms 9 and force them apart as depicted clearly in Fi'g. 5, thus disengaging the bobbin holders 8 from the bobbin 5 and permitting the latter to be easily detached. When. another bobbin is applied A to the spindle Aand the latter forced downwardlyV into the recess 2, the arms 6 again move the holders 8 to operative position. y
A fiat spring 12 is inset in a recess 13 in the bottom of the shuttle and bears eccentrically against the pivoted end of the spindle 3 to hold the latter in lowered position, and the iXed ends of the arms 6 are `preferably beveled at 14 for coaction with the beveled end l5 of the spindle in forming a Hat surface for contact with the spring when said spindle is raised, whereby said spring will also retain the spindle inthe last named position.
From the foregoing taken in connection with 'the accompanying drawing, it will be obvious that I have provided an extremely simple and inexpensive bobbin holding means, yet one which will be highl efficient, reliable and durable. Since pro ably the best results are obtained from the details shown and described, they are by preference followed, but within the scope of the invention as claimed, considerable latitude is allowed for making such minor changes as occasion may dictate.
I clain: In combination with a shuttle having the usual bobbin recess and a spindle pivoted at one end to swing into said recess, a pair of yielding arms disposed one at each side 4upper ends in one end of said bobbin recess,
and having downwardly diverging lower ends disposed between said spindle and said yielding arms and in the upward path of the former, lwhereby raising of said spindle will spread said yielding arms to releas the bobbin.
In testimony whereof I have hereunto set my hand. 4
