HAiWD-THREADIN SHUTTLE.

Specification/o1 Letters Patent.

Patented Feb. 18,1913.

Application filed July 27, 1912. Serial No. 711,933.

To all whom. it may concern Be it known that I, OCTAVIEN DALroNn, a citizen of the Uni ed States, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in, Hand- Threading Shuttles, of which the following is a specification.

This invention relates to loonrshuttles, particularly of that type commonly known as self-threading or hand-threading shuttles.

The object of this invention is to provide an attachment for shuttles having the usual delivering eyes and having continuous walls-that is, walls having no slits and therefore retaining their original strengthby means of which the strength of the shuttle at the eye is greatly increased and the thread fromthe cop or spindle may be positively pushed through the eye, which object, among others is accomplished by the construction and combination of parts hereinafter more particularly set forth and claimed, and illustrated in the accompanying drawings.

In the accompanying drawings: Figure 1 represents a plan view of so much of a shuttleas is necessary to illustrate the invention, said shuttle carrying the invention in one of its embodiments, the thread from the 'cop being placed in the thread receiving slot; Fig. 2, a vertical crossesectional view on the line 2 -2 of Fig. 1, the slide being drawn in and showing the intermediate position ofthe arm and link in dotted lines; Fig. 3, a similar view,-the slide being extended; Fig. 4, a longitudinal vertical scc tional view on the line 1-et.of Fig. 1, looking inthe direction of the arrow, showing the thread lying inthe grooves; Fig. 5-, an enlarged top plan slew of the threader and adjacent parts of the shuttle body, the top part of the eye being partially broken away to show the carrier 3 carrying the thread C and being in intermediate position; and Figs. 6, 7 and 8 represent details of various parts. I

Referring now in detail to the drawings, A designates the body of the shuttle, B the cop or spindle, C the thread carried by said spindle and D the usual V-shape feeding slot or groove" running transversely to the slide or carrier and longitudinally of the said shuttle body. The shuttle body A is transversely bored in its forward end at the usual point for the eye, said transverse bore having communication on its upper side and at the middle point thereof with the above mentioned slot D which runs transversely thereto, and on its lower side with a transverse slot forming communication between inwardly and downwardly tapering recess E running transversely of said body A and the slot in said eye 1. An eye 1 is secured in said transverse bore by means of screw threaded engagementat both ends thereof and has a narrow slot which registers with the transverse slot above mentioned, when the said eye 1 is in position. Said eye 1, which is tubular and of a width equal to the width of the shuttle at this point, is further provided with a thread receiving slot 2 ofusual shape, which registers with the bottom of said V,-shaped feeding groove D above mentioned. By reason of its tubular shape this eye 1 forms a strong brace for the parts of the shuttle A at this point. A slide or carrier 3 of cylindrical shape and of such diameter as to make a snug fit in said eye 1 is reciprocated therein at 5 in the forward part of the slot 19 in said carrier 3, see Figs. 2, 3 and 5-; and at the other end at 7 to the bifurcated upper end 1 of alink 8 slidably mounted in a deep recess 5) in spring pressed wheel 10 (see Fig. 3) having its edge milled, knurled or otherwise roughened to provide a frictional surface for the partial rotation by hand of said wheel. This wheel 10 is mounted in bearings 11 of plate 12 attached to the bottom of said shuttle by means of screws 13 or in any other convenient manner-and extends upward into the transverse recess E above mentioned, which communicates with the interior of the eye 1 by means of the transverse slot above mentioned. fiaid slide or carrier 3 is provided with a recess 18 in its rear end and extending from the upper to the lower external faces thereof, to receive the bifurcated upper end' of link 8 during the various positions of this link 8 and arm 41 during the travel to and fro of the carrier 8. This slide or carrier 3 is further provided with a central slot 19 extending from a point near the forward end of said carrier to and communicating with the recess 18. It is in this slot 19 that the forward end of arm,, 4= is pivoted, as above stated; so that both.the arm 4 and the link 8 have perfect freedom of motion in all their dillerent poby means of an arm 4 pivoted at one end' reaches to the thread-receiving slot 2 and is provided on its front end with an undercut lip 16 and on each side with a thread receiving groove 17 which communicates therewith, said grooves 17 being in the same horizontal plane.

The operation is as follows: The thread C is placed inv the thread-receiving slot 2 in advance of the lip 16 of carrier 3. The

wheel 10 is then'turned through an arc of about 90 degrees, against the action of spring 14. This, through arm 4 and link 8 slidablymounted in recess 9 in said wheel to simplify and expeditcthe assembling and disassembling of the device, -forces the carrier 3 to its outermost position, ,the thread fitting in the grooves 17 so as not to bind the movement of said carrier. The thread C is now removed from the lip of said carrier and held, the wheel 10 is re leased and by means of spring 14- it and the carrier 3 are both withdrawn to their original positions ready to repeat the operation.

'Having thus described my invention,

what I claim as new and desire to secure by Letters Patent is:

1. A shuttle body, a transverse eye secured therein and a carrier adapted to re: ciprocate therein, in combination with a spring pressed wheel, a link slidably mounted therein and an arm pivoted at one end to said link and at the other to said carrier.

2. A shuttle body, a transverse tubular eye mounted therein and a carrier adapted to reciprocate in said tubular eye, in combination' with a wheel, a link slidably mounted therein, an arm pivoted to said link at one end and to said carrier at the.

other, and means for normally holding said carrier in its innermost position.

3. A shuttle body, a transverse tubular eye, mounted therein and a carrier adapted to reciprocate in said tubular eye, in combination with a Wheel, a link slidably mounted therein, an arm pivoted to said link at one end and to said carrier atthe other, and means for normally holding saidcarrier in its innermost position, said carrier being provided with a slot and a recess to receive respectively the said arm and the end of said link in the various positions of th latter.

n testimony whereof, I have signed my name tothis specification in the presence of two subscribing witnesses.
