SHUTTLE-EYE.

Specification of Letters Patent.

Patented Feb. 27, 1912.

Application filed February 24, 1910. Serial No. 545,759.

To all whom it may concern:

Be it known that 1, JOHN H. HorKiNsoN, of Fall River, in the-county of Brlstol and Commonwealth of Massachusetts, have invented an Improvement in Shuttle-Eyes, of

which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The objects of this invention are to provide a shuttle eye which can be easily threaded without applying the lips to the shuttle, and when threaded will retain the yarn securely in the eye, and which will apply a proper amount of tension to the yarn.

In the accompanying drawings, Figure 1 is a top View of a shuttle to which my improved eye has been applied. Fig. 2 is a side view thereof showing the eye in dotted line. Fig. 8 is an isometric view of my improved eye.

My device consists of a single piece of metal of peculiar shape. The shank B is flat, and is provided with a hole through which it is fastened to the front part of the shuttle body A, by the screw C. To the rear of the shank portion, the metal is broadened and bent down as shown at forming a bed-piece, which rests against the body of the shuttle and greatly assists in holding the eye in position, under the repeated shocks caused by the operation of the shuttle. At the lower edge of the bed-piece If, it is bent back upon itself forming a small tube. The inner end of this tube is at or near the axis of the shuttle spindle; its outer end pierces the side of the shuttle and is flush therewith. It will be noticed that the metal is so bent, as to form a practically complete round tube in which the yarn runs. I regard this small tube as an essential and important part of my invention. The slit along the top, through which the yarn enters the tube when the shuttle is threaded- I is so narrow that the yarn does not in practice work into it while the shuttle is in operation. The size of the tube may be suited to the number of the yarn which is being used; and the tube serves, not only as a yarn guide, butalso as a tension device. Above the tube, the metal is continued upward and forward parallel with the bed-piece and shank and very close thereto, forming a guide-piece b which terminates in the rounded point 6.

In threading the shuttle, a loop of yarn is caught under the point of the guide-piece b. The free end of the yarn is then drawn outward and backward close to the shuttle. This causes the inner end of the loop, which is attached to the bobbin, to slide down along the inner edge of the guide-piece until it reaches and enters the inner end of the tube at b The outer and free end of the loop slides down the outer edge of the guide-piece b, and enters the tube at the outer end 12 The yarn slips down between the guide-piece and the bed-piece and enters the tube. The yarn is then grasped at the outer end of the tube, is pulled clear, and the shuttle is threaded. The course of the yarn is shown by E e. I regard the shape of the guide-piece, as well as its proximity to the bed-piece and shank, as of importance. The yarn is retained in position by an inner lock-piece Z2 and an outer lock-piece 6 The inner lock-piece is integral with the bed-piece. It is bent out, over and parallel with the guide-piece b leaving just sufficient clearance,'between the inner edge of the guide-piece and the inside of the lock-piece, for the passage of the yarn when the shuttle is threaded. It prevents the inner end of the yarn from being drawn out of the tube, by the ballooning action of the yarn, when the shuttle is in use. The shape of this inner lock-piece is peculiar and important. The upper edge has a downward slant; the point is rather broad and rounding; the lower edge slants slightly upward making a round-pointed wedge of irregular shape. The reason for this peculiar shape of the inner lock-piece is as follows: It often happens in the operation of a shuttle that the yarn balloons forward, due to its own momentum and the sudden stopping of the shuttle at the end of the lay. Occasionally, the ballooned thread catches under the lock-piece, in which case, when the shuttle has started back on its return stroke and the yarn tightens, it will, owing to the peculiar shape of this inner lock-piece, slip off it and not break. The outer lock-piece b is integral with the bed-piece b and is bent across the space between the bed-piece and the guide-piece just above the tube. There is just sufiicient space between the outer edge of the guide-piece and the inner side of the lock-piece b to permit the passage of the yarn When the shuttle is threaded.

Having thus described my said invention, I claim 1. A shuttle-eye consisting of a bed-piece laid back on itself to form a guide piece and crimped to form a slotted tube, the inner end of said tube being in line With the point of a shuttle spindle, and a lock-piece extending from the bed-piece over the edge of the guide-piece.

2. A shuttle-eye consisting of a bed-piece laid back on itself and forming a g'uidepieee extending close to and parallel with the bedpiece, an inner lock-piece extending from the bedpiece over and beyond the inner edge of the guide-piece, and an outer lockpiece extending from the bed-piece over the outer edge of the guide-piece.

3. In a shuttle-eye a bed-piece, and a gnide-piecein combination With a lock-piece having the shape of an irregular curvilinear triangle With rounded point extending from the bed-piece over and beyond the inner edge of the guide-piece.

4. A shuttle-eye consisting of a bed-piece adapted to be fastened to the shuttle, a longitudinally slotted tube integral with said bed-piece, a guide-piece integral with said tube, and a lock-piece extending from the bed-piece over and beyond the inner edge of the guidepiece.

5. A shuttle-eye consisting of an angular bed-piece and a guide-piece parallel thereto connected at the loWer edges by a tube slotted longitudinally between said bedpiece and said guide-piece, and a lock-piece extending from said bed-piece over and beyond the inner edge of said guide-piece.
