To all whom it may concern Be it known that 1, ROBERT N. ALLEN, a citizen of the United States, residing at Methuen, in the county of Essex and State of lVlassachusetts, have invented a new and useful Improvement in Hand Threading Shuttles, of which the following is a specification.

This invention pertains to certain new and useful improvements in hand threading shuttles, and relates more particularly to a new, novel and improved form of threading device.

The object of the invention to provide a threading device which is of simple construction and in which the entire structure is termed from a single sheet metal blank.

In the drawings: Figure 1 is a fragmentary top plan view of a shuttle having the present invention applied thereto. Fig. 2 is a side elevation. Fig. 3 is a top plan view of the blank from which the device is formed. Fig. 4 is a section taken on the line l4l of Fig. 1, the shuttle body being omitted. Fig. is a section taken on the line of Fig. 1, and Fig. 6 is a section taken on the line (3-43 of Fig. 1.

Tn carrying out the present invention, a sheet metal blank 1 is employed which latter is bent to form a body of 'Uehape in cross section, in which 2 designates one of the sides, 3 the other side and 1 the bottom. The outer end of the side 2 is curved inwardly as indicated at 5, and abuts an end wall (3 formed by the cavity 7 provided in the shuttle body to conformably receive the device. The side 3 has its top extended outwardly and turned at right angles to form a flange 10 which occupies a position substantially at right angles to the side 8. The flange 10 is received in a cut out portion .11 provided therefor in the top face of the shuttle body. The flange 10 is provided with a curved edge 12 which overlies the top of the diagonal thread slot 13 which latter at its lower end connects with a delivery eye 1a. A finger 15 at the free end of the flange 10 is bent downwardly so as to project adjacent the end wall 5 of side 2. The side 3 is formed with an eye 17 which is located at the base end thereof and forms a 11001; portion 18 that is spaced from a cutaway portion 19 formed on the bottom a. A pin 22 is located adjacent the eye 17 and engages the thread in its passage to the latter. The

pin is'preferably secured to the wall 3 by passing the ends thereofthrough openings formed in the wall. 3 and bottom a, as clearly shown in Fig. (3. The sides are formed with openings 23 and 2a and receive a screw 25 that is passed theretln'ough. The screw 25 has its threaded end in engagement with a threaded plug 26 secured in a depression 27 in. the shuttle body. A spacing block 28 is placed over the screw 25 between the side walls 2 and 3 and acts to maintain the walls in their relative positions as shown in Fig. 5. The spacing block 28 has a rounded or curved upper face 29 and an eye 30. A friction device composed of a felt block 31 is located between pin 22 and the front end of the block 28, and is held in place by frictional engagement with the parts.

In operation the thread is drawn so that it engages the rounded face 29 of block 28, and the end wall 5 and the finger 15 of the flange 10, the thread being drawn downwardly between the wall 5 and finger 15 entering the eye 30, and engaging the outer curved end 16 of the side 3, and on further movement of the thread the same passes under the hook 18 and thence enters the eye 17 which latter alines with the delivery eye 11. It will be understood that the thread is guided by the curved end 12 of flange 10 to enter the slot 13 at the same time that the thread rides down 011 the end 16 of wall 3.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a hand threading shuttle, a threading device of U-shape in cross-section, one of the sides having its outer end bent at right angles toward the other side, the sec- 0nd named side being bent outwardly to form a flange, said flange being formed with a finger that projects downwardly, and extends outwardly in the same direction that the right angular end extends and is disposed substantially parallel with said right angular flange, the space throughout the lengths of the sides and the right angular flange an d the finger being completely open, whereby the thread can be introduced in the device by direct downward movement so as to enter the space between the said sides and the space between the right angular flange and said finger, the outer end of the second. named side being curved downwardly and terminating in an eye anda hook which is spaced from the bottom of the device to permit the thread to enter the eye.

2. In a hand threading shuttle, a threading device of U-shape in cross-section, one of the sides having its outer end. bent at right angles toward the other side the second named side being bent outwardly to form a flange, said flange being formed with a finger that projects downwardly and extends outwardly in the same direction that the right angular end extends and is disposed substantially parallel with said right angular flange, the space throughout the lengths of the sides and the right angular flange and the finger being completely open,
