SPECIFICATION forming part of Letters Patent No. 375,104, dated December 20. 1887. Application iiledDlcemher 20, 1886. Serial No.222,019. (No model.)

.To @ZZ w/'wm/ it may concern:

Beit known that I, FRANK H. STETsoN, of Lawrence, in the county of Essex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement 1n Loom-Shuttles, of which the following is a I ull, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to a shuttle having a spindle especially designed forholding worsted bobbins; and it comprises a spindle made in two longitudinal sections, one of which is permanently hinged to the base or rear end of the shuttle and the other of which is adapted to beheld thereto, when the spindle is in operative position, at its butt-end by means of a bar or stud, which extends across the spindlecavity close to the hinge, and the spring which holds the spindle in its straight position in the shuttle-cavity, and. at its front end by engagement with the front end of the hinged mein-v ber of the spindle.

Referring to the drawings, Figure 1 is a vertical longitudinal section of a shuttlel having the features of my invention. Fig. 2 is a longitudinal section showing the same parts as shown in Fig. l, but in a different position. Fig. 3 is a view of the two parts of the spindle removed from the shuttle. Fig. 4 is aview of the same parts, showing a slight modication. Fig. 5 is a detail view. Fig. G is a cross-section of the divided spindle on the line indicated by the dotted arrow in Fig. 3.

A is the shuttle-body.

c is the cavity.

B is the section or part of the spindle which is hinged or pivoted by the pivot b to the shuttlc-body.

Gis the removable section Vof the spindle. The part B has at its base or innerend the extensions or plates b 112, which are substantially parallel with eac-h other in the direction of their length, and which form between them a dovetail holding recess or cavity, b3, for the reception of the butt-end ofthe other section or part of the spindle. These plates or projections each have a cross note-h or groove, b4, which is formed to be in line with the stud or pin b5 when the spindle is in operative position. The removable section of the spindle has its butt or inner end, c, shaped to fit the dovetail recess or cavity b3 and the .cross groove or notch c', which receives or is moved upon the erossstud b5 when the spindle is moved to its operative position. rlhe hinged section B has the flat surface b, the curved surface bl, and is somewhat shorter from its shoulder bs to its end than the full length ofthe complete spindle. The removable section C has the flat surface ci, which fits the fiat surface of the hinged section, the curved surface c3, and the fullsection or end c, to the end of which the button or disk cb is fastened, and the outer end of the hinged section is attached to the outer end of the removablesection in any desired way. I have shown in the drawings two methods of attachment.

In Fig. 3 the hinged member is represented as provided with a short pin or reduced section, b, at its end,whieh fits the hole c, formed in the full part of the removable section of the spindle.

In Fig. 4 I have shown the outer end of the hinged section as cut away or tapered to form an extension which shall entera recess of corresponding shape'formed in the full end of the detachable section. The first-named construction I consider preferable. There are other ways by which the outer ends may be secured, and I would not confine myself to the especial forni herein mentioned.

In use the detachable section of the spindle is slipped through the bobbin-hole until the disk o r button bears against the outer end of the bobbin. This brings the butt or inner end of the removable section beyond the butt ot' 4the bobbin. The flat surface of this inner end is then placed upon the dat surface of the hinged section oft the spindle, and the bobbin and detachable section are moved thereon until the butt of the detachable sectionenters the dovetail cavity or hole at the butt of the hinged section, and the reduced section or end of the hinged section enters the hole or cavity in the end of the detachable section, and the bobbin is `confined between the button or disk c5 and the base-shoulder bs of the spindle. The spindle is then moved into the shuttle-cavity, and the spring D serves to hold or maintain itin the cavity, and the two sections of the IOO spindle are locked together by the cross-stud, so that endwise movement of the movable section of the spindle in relation to the fixed section cannot take place while the spindle is in this position.

It will be seen that this construction affords a very simp'ie way of placing and removing the bobbin, and that the button or disk serves not only to hold the bobbin upon the spindle, but also as a guide over which the yarn is drawn from the cop.

It will be seen that by the use of a spindle of this construction, having the disk or button c5, there is a very even tension upon the yarn in weaving from the bobbin or cop as the yarn passes over aguiding-surlace, which is always of the same sizeg'also, that the disk serves to permit the use of split or cracked bobbins, because it serves to hold the yarn away from the edge of the bobbin. being always larger than the end of the bobbin.

I would say that I do not conine the invention to its use with Worsted bobbins, but may employ it for any purpose Where a divided spindle with an end disk can be used for the `purpose of holding a spool, bobbin, or cop in 'a shuttle.

of the United Statesl. The combination, with a shuttle-body, of a longitudinally-divided spindle,the two parts of which are connected together at or near their opposite ends to prevent lateral displace ment, the removable part of the said spindle being provided with a disk or button, substantially as set forth.

2. The combination, with ashuttle-body, of a longitudinally-divided spindle, one part of which is attached to the said body and is provided at its butt-end with a holdng-recess,the other or removable part of the said spindle being provided at its outer or free end with a disk or button and having its inner or butt end tted to fill the said holding-recess, substantially as set forth.

3. The combination of a shuttle-body with a tWo-part spindle,one ofWhich parts is hinged to the shuttle-body and has the plates b b2 and cross notches or grooves b4, and the other of Which has an end section having a cross groove or notch, c', and is adapted to t the space between the said plates and the locking-bar b5, substantially as described.

4E. The combination, With the shuttle-body, l

of a longitudinallydivided spindle, one part of which is hinged to the said body and is provided at its butt with a dovetailed' holding-recess, the other or removable part of the said spindle having its butt-end fitted to the said dovetailed recess and being provided at its outeror free end with a disk orbutton, substantially as set forth. y

5. The combination, with a shuttle-body and a longitudinally-dividedv spindle, one part of which is provided at its butt with a holdingrecess and the other part of which has a butt iitting the said recess, ofthe cross-stud or locking-bar If and the spring D, substantially as set forth.

6. Thecombination, With ashuttl'e-body, of a longitudinally-divided spindle consisting of the sections or parts B and C, the part B having its outer end reduced and being provided at its butt or hinged end With a holding-recess, and the part C having near its outer end a hole or cavity for the reception of the said reduced end and having its butt-end fitted to fill the said holding-recess, substantially as set forth.

7. The combination ofthe shuttle-body with a spindle made in two longitudinal parts, one of which is hinged to the spindle-body and the other of Which is removably attached at its butt and point ends to the hinged part of the spindle, and a disk or button secured to the end of the removable part, substantially as described.
