SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 788,937, dated May 2, 1905.

Application iiled June 17, 1904. Serial No. 212,946. (Models.)

To all whom, it Wha/y concern;

Be. itknown that I, JOSEPH HERBERT NAsoN, a citizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Shuttles, of which the following is a specification, reference being had therein to the accompanying drawlngs.

Figure 1 is a perspective view of my improved shuttle eye-block, a part being broken away for greater clearness. Fig'. 2 is a side elevation of the eye-block looking at its threaddelivery side. Fig. 3 is a front end elevation. Fig. 4 is a top plan view of one form of shuttle embodying the present preferred form of my new eye-block. Fig. 5 isa side elevation of the front end of the shuttle with the eyeblock in place. Fig. 6 shows a modification in which an old form of eye-block A, substantially such as shown in Keeleys United States Patent No. 505,203, of September 19, 1893, is combined with a bent-wire thread-delivery eye and overhang, the inner end portion of the wire being bent to form a lateral thread-guiding continuation of the guide-rib of the eye-block to the thread-delivery eye. Fig. 7 shows the bent wire which forms the delivery-eye, its overhang, and its threadguiding inward extension.

The object of my invention is to produce a shuttle which may be threaded with improved facility either by hand or automatically and which when running will haveits thread, yarn, or filling kept down, and so properly in the thread-passage from between the outer end of the cop or bobbin to a point outside of the threaddelivery eye, thus preventing the thread from flying up out of the lengthwiseextending portion of the thread-passage in the front end of the shuttle and becoming snarled or broken, and thus preventing the thread from flying out of the delivery-eye.

In the drawings illustrating the principle of my invention and the best mode now known to me of applying that principle, A is the shuttle, having' the usual bobbin or cop space a. Itis herein shown with bobbin-holding jaws a', such as commonly used in automatic bobbin-changing shuttles.

Eye-block B has a lengthwise-extending thread-passage 1 from the front end of the bobbin-space forwardly to the recess a2 in the top wall of the shuttle near the front end thereof. Thisthread-passage is an open groove in the top wall of the thread-eye and may be of various formations without departure from my invention; but it is preferably diagonal to the longitudinal axis of the shuttle, whereby an overhang Qis more conveniently formed at the rear end of the eye-block to keep the thread from jumping up out of the rear end of the thread-passage. At the front end of the passage 1 there is the usual beak 3,the point of which enters the recess4 in the opposed opposite wall of passage 1. The top wall of the eye-block is downwardly inclined at the approximately triangular portion (indicated by 5, 6, and 6a) as heretofore, the overhang 2 also slanting downwardly at the rear end of passage 1 to facilitate either the manual or automatic guidance of the thread'down into passage 1 in threading the shuttle. The eyeblock is provided with a downwardly-extending thread-guide 7 in the form of a rib, the under thread-guiding edge of which extends downwardly from the under side of the beak, near the outer end thereof, to a point in a horizontal plane at and below which the side delivery-eye 8 is formed, the rib or guide 7 extending outwardly and slightly downwardly to a complementary thread-guiding rib 9, which terminates at 10 in the thread-delivery eye. The ribs 7 and 9 together constitute what may be called the delivery-eye guide and may be varied in constructional form without departure from my invention.

l/Vhen the thread is led from the bobbin forwardly and laid in passage l and carried past and under beak 3, its outwardly-extending portion, which may be in the hand or attached to a pin in the loom and which is the cloth-going portion of the thread, rides downwardly and outwardly to the thread-delivery eye, being guided in this movement by the edges of the ribs 7 and 9-that is, by what I call the delivery-eye guide. When the thread extends from the bobbin-space through the eye-block and out of the side deliveryeye, it may ride over the friction-filling 11,

IOO

if that be used, and is then at the bottom of the lengthwise thread-passage 1 and bent on the vertical guide-pin 12, coming out at the delivery-eye.

To keep the thread down in the deliveryeye, I recess at 13 the rear outer wall of the lateral lug 14 of the eye-block and provide an upwardly and rearwardly extending fingerlike extension 15 at the front part of such lug, the front end 16 of the finger entering the recess 13 and overhanging the rib 9, a clear space forming a thread-passage being left between opposed walls of rib 9 and recess 13 on the one hand and of the finger 15 on the other hand. From the upper side of finger 15 the eye-block curvesV upwardly and forwardly, forming the under wall extension 18 of the exterior downwardlyextending thread-passage 18, the upper wall of which is formed by the outer front edge 19 of the top wall of the eye-block. However, steel pins, such as generally used and vertically set in the eye-block at each side of the thread-delivery eye, are preferably provided for its protection against the friction of the thread, and the front upper end of extension 18 is preferably pinned to the shuttle at 21 to keep its free end from working loose under shocks to which the shuttle is subjected.

The eye-block is shown with the usual shank b and transverse bore b. A screw b2 through the shuttle-walls and bore holds the eyeblock fast in the shuttle.

In Fig. 6, showing a modification, an old -and well-known form of eye-block A is shown,

formed with the thread guide rib a. To guide the thread from this guide-rib a (which is the rib 7 of the preferred construction) into the thread-delivery eye, I form a wire, as shown, with a tang a', which is a means of confiningthe front portion of the wire in the shuttle at a2. From tang a2 the wire eX- tends rearwardly along the side of the shuttle to the recess a3 in the side of the shuttle and rearward of the delivery-eye opening. The wire is then bent at a? and carried forward to the front side of the delivery-eye opening, where it circles downwardly and upwardly and forms a circular bushing a5 for said opening, the inner or forward end portion of the wire being carried inwardly at a, so as to receive the thread from the rib a and guide it downwardly into the interior of the bushing as prevents the thread in the delivery-eye from jumping up out of the eye.

Vhat I claim is-- 1. 1n a shuttle having a thread-delivery eye, the combination of an eye-block having a lengthwise thread-passage and overhanging beak, and a downwardly-extending guide-rib with a lateral thread-guide between the rib and the thread-delivery eye; and an overhang for said eye; the lateral guide leading the thread from a lower part of the rib to the delivery-eye.

2. In a shuttle having a thread-delivery eye, the combination of an eye-block having an overhanging beak and a downwardly-extending guide-rib with an integral lateral thread-guide between the rib and deliveryeye, and an integral finger forming an overhang for the delivery-eye.

' In testimony whereof l affix my signature in presence of two witnesses.
