To (If/Z rch/om. t may concern:

Be it known that I, J EAN BAPTISTE IDAUDE- LlN, a citizen of the United States, resldlng at Fall River, in the county of Bristol and Conil monwealth of Massachusetts, have invented certain new and useful Improvements in Sell-Threading Leoni-Shuttles, of which the following is a specification. l

This invention relates to selfthread1ng shuttles, and particularly to that class 1.11 which the thread when in the deliveryeye 1s |ection of some sort.

will be capable of easy and accurate adjustment and which will be held irinly in place in the shuttle-body.

To this end the presentinventionconteni! plates Athe use of a delivery-eye or bushing which shall have such a construction and ari rangement of parts as will make possible such an adjustment and ease and accuracy-in the dis osition of the slots in the-shuttle-body an bushing, through which the thread must pass to enter the eye.

E 1s an opening throng In the drawings', in which like letters of reference indicate corresponding parts throughout, Figure l is a view of one end of such a shuttle. Fig. 2 is a section on the line 2 2 Fig. l. Fig. 3 is a view of the delivery-eye, and Fig. 4 a modication of the same.

' There is shoWn a shuttley of the type above mentioned, the actual shuttle shown being that of my Patent 756,592. In the shuttle-body A is a delivery-eye D, in which is located a bushing or delivery-eye This eye consists of atubular body portion B, closed at one end and having a threaded and slotted head H, the slot h being adapted to receive a screw-driver'for driving the eye in-*the shuttle-body and adjusting the saine after it is located therein. The body portion vB ma be also screw-threaded to engage the WoodI of the shuttlefbody and act as a transverse strengtheni -bolt.

` which the thread f the passage F in the shuttle-body. time the eye becomes displacedorthe edges of arts may be is drawn into the tubular body B, and E2 is a slot connected therewith to allow the thread, which passes through the threading-passage F in the shuttle-body, te enter the eye. The

l portion of the eye E adjacent to this slot is l cut down or cleared,

thread to pass between the eye and the shuttle-body; This cleared portion S may be in g the' forin of a sunken or recessed area, as' l shown in Fig. 3, or the body B may be gradl ually thinned or tapered at this edge to allow deflected or held away from the passage by which it entered by a bar, shoulder, or pro- F It is particularly de- .sii-able in-these shuttles to have an eye which the thread to enter the slot, as shown in In assembling the parts the eye is introduced into the shuttle-body and screwed in, it being turned until the s'lot E2 registers with if :1t any the passages wear down, the immediately adjusted by snnp )nturning the bushing with a screw-driver 1n the slot z as at S, to allow the- A What l therel'ore claim, and desire to se l cure by Letters lat'ent, is-
