BOBBIN-SPINDLE.

Specification of Letters Patent.

Patented May 5, 1908.

Application filed. March 1, 1906. Serial No. 303,668.

To all whom 'it may concern:

Beit known that I, HORACE "WYMAN, a citizen of the United States, residing at VVorcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Bobbin-Spindles, of which the following is a specification.

My invention relates to improvements in bobbin spindles, and to that description of bobbin spindles which have one en'd provided with two or more annular projections or rings thereon to engage with yielding jaws in a shuttle, and a retaining head for the bobbin at the other end, which acts also as a bearing for the filling on the bobbin.

The object of my invention is to improve upon bobbin spindles of the description referred to, and more particularly to provide an end with two or more annular projections thereon to engage the yielding jaws in a shuttle, and a spindle or support for the bobbin, made separate from the head, and adapted to be attached thereto, and detached therefrom, and havingV on one end a retaining head for the bobbin.

Referring to the drawing 1-Figure l is a plan view of a self-threading shuttle of ordi nary' construction, having spindle holding jaws, and showing a spindle embodying my improvements combined therewith, and a sectional view of a iilled bobbin on the spindle. Fig. 2 shows, on an enlarged scale, a central longitudinal section of the spindle and bobbin, shown in Fig. l, detached. Fig. 3 is an end view of the spindle head shown in Fig. 2, looking in the direction of `arrow a, same iigure, and, Fig. 4 corresponds to Fig. 2, but shows the removable retaining head partially detached from the head of the spindle, and the bobbin moved down slightly on the spindle.

In the accompanying drawing, 1 is a selfthreading shuttle which may be of any usual and well known construction, and is provided with a pair of yielding holding jaws 1', in the usual way.

The spindle embodying my improvements consists of the head or end 2, having two or more annular projections 2l thereon, adapted to engage with the jaws l in the spindle.

The head 2 has a central opening 2 therethrough, of circular shape in cross section, at one side, and straight at its opposite side, as shown in Fig. 3. Vithin the opening 2 through the head 2, extends a leaf spring 3, which is secured at one end, in this instance by a screw or rivet 4, at the inner end of the head 2 on the hat side of the opening 2, and has at its other end a cam-shaped projection 3.

The other part of the spindle consists of a rodor support 5, forming the spindle for the bobbin 6, having filling 6 thereon.

The rod or support 5 at its inner end is preferably of reduced diameter, as shown at 5, and has a recess 5 therein to receive the cam-shaped projections 3 on the spring 3. Above the reduced diameter 5 of the spindle 5, the spindle is of somewhat larger diameter as shown at 5, and is adapted to enter loosely the central opening 2l in the head 2. Beyond the part 5' of the spindle 5 the diameter of the spindle is increased, as shown at 5, to correspond with the size of the central opening through the bobbin, being a little smaller than said opening, and forming an annular shoulder or ange to butt against the inner end ofthe head 2, as shown in Fig. 2. Between the part 5 of the spindle 5 and the outer end of the spindle, the body of the spindle is preferably of reduced diameter, as shown.

The outer end of the spindle 5 has the head or enlarged end 7 thereon, of disk shape and adapted to extend over the tip end of the bobbin, and having the reduced portion 7 to extend loosely within the central opening in the outer end of the bobbin.

The operation of my improved bobbin spindle will be readily understood from the above description in connection with the drawing.

When it is desired to remove the bobbin 6 from the spindle, or to place a lspindle on the bobbin, the part 5 is drawn out from the head 2, being yieldingly held therein by the spring 3; the bobbin is then drawn 0H from the spindle 5. After a new bobbin has been placed upon the spindle 5 by inserting the reduced end of the spindle throughthe central opening in the bobbin, the spindle 5 is attached to the head 2, by inserting the reduced end 5 through the central opening 2 in said head, and pushing it down until the cam-shaped portion 3 on the spring 3 enters the recess 5 on 'the reduced end 5/ of the spindle 5. The spindle 5 may beinserted in the head 2 without regard to the position 0f It Will be understood that the detailsa of 1 construction of ymy improvements may be varied if desired.

Having thus described my invention, What l claim as new and desire to secure by Letters Patent is:-

1. A bobbin spindle, comprising a head provided With tWo or more annular projections, and having a central longitudinal opening therethrough, and a flat or leaf spring contained ,Within said opening, attached at one end, and with its other end adapted to extend Within a recess in a support for the bobbin, and said support, adapted at one end to extend loosely into the central opening in said head and to be retained therein by said spring, and having an enlarged end or head at its other end to retain the bobbin thereon.

2. In a bobbin spindle, the combination with the head having a central opening therethrough, and a spring extending entirely Within said opening and attached at one end end enlarged or provided with a head to retain the bobbin on said support.

3. In a bobbin spindle, the combination With the head having a central opening therethrough, and a spring extending entirely Within said opening, and attached at one end in said head, and adapted at its other end to engage one end of the bobbin support, of said bobbin support, adapted to extend at lone end loosely Within. said head, and to be re'- tained therein by said spring, and having an annular shoulder to engage the end of said head, and an enlarged end or head on its other end adapted to retain the bobbin on said support.
