FLIER.

Application filed November 19, 1923. Serial No. 675,519.

To all whom it may concern:

Be it known that LJAMEs H. HARNETT, a citizen of the United States, residing at Nutley, in the'county of Essex and State of New Jersey, have invented certain new and useful Improvements in Fliers, of which the following is a specification,

This invention relates to fliers used in spinning and the like operations and particularly. to fliers, used in spinning hemp, jute and such materials, of the type characterized by a tubular central upstanding head having a lateral, eye for the roving andiby two depending tubular and longitudinally slitted legs into one of which (by its slit) th rovingis entered so as to be guided thereby between the. eye in the head and the eye alsoprovided at the lower end of the leg. That I will herein term the body part of these devices consists of a one-piece structure comprising the legs and the up,

per connection between them, the head as well as the mentioned eyes in the lower ends of the legs being separate parts attached to the body part. Heretofore this body part has been a forging which, though as to its slitted tubular legs it was formed so that the material had substantially uni form thickness throughout, was thicknened up as to the mentioned upper connection between the legs, both so as to give it strength in this portion necessary to prevent the legs yielding outward in response to centrifugal. force or inward due to a fall or blow and afford a substantial base forattachment of the head, which was held in place by a screw passed up through a hole in the connection and screwed into the head. On account of the forging the expense of making these body parts was very great, especially as it is very ly balanced and be nicely finished. My invention seeksto provide a flier body part which shall be very much cheaper to manufacture than the ordinary one, above described, and which shall if anything be stronger, though lighter in weight, than the same. My invention further seeks to provide a flier which shall be in general cheaper, stronger and otherwise better and moreefficient in use than the ordinary flier.

- Fig. 5 shows the blank from which the body part is made;

Fig. 6 is a transverse sectional view of the upper part of the improved flier through its greatest dimension; and r Fig. 7 is a vertical sectional viewof an other form of the improved flier.

To form the improved body part of the flier an elongated blank is provided, such as is shown in Fig.8 5, the same having the wide central portion a and the slightly tapered extremities 6, each of which may be reduced in width as shown at b. This blank is formed from a piece of sheet metal, as sheet steel, being of substantially uniform thickness throughout. For the form- 4 is a sectional view on line 44:

ing of the eye-receiving hooks 9 it may have the extension pieces 0 separately formed and then welded, to its reduced extremities, one of these being indicated by This blank is approximately from end to end then shaped, after heating, vtolongitudinally U-shaped channeled form-(Fig. 4;) and then, at equal distances from its central transverse line, the extremities b are bent off into parallelism with each other and each opposite to the direction in which the. channel opens. This produces the two legs 0?. and the con nection 6 between them; The connection e is left transversely U-shaped, but each leg at preferably has the side edges ofits channel bent inward toward each'other, as shown in Figs. 2 and 3, but so as to leave a longitudinal slit d at the outside of the leg, which it is better to do after the bending off of the extremities of the channeled blank to produce the legs, but this is not indispensable. A hole 6' may be provided centrally in the connection 6 at any stage in the forming of the body part. The. eyes 7 are attached at any stage by bending the extensions ointo 1 the form of hooks -g so as to embrace and hold said eyes, as shown in Figs. 1 and 2. It will be noted that the channeled form prevails clear across the connection and substantially to the end of each leg; in other words, each side wall of the connection forms with the corresponding side wall of each leg a single uninterrupted wall, the continuity or uninterruptedness of which is of greatest imporance especially within the length of the connection where the influence of centrifugal force to throw the legs of the fller outward when in rotation, or the effect of a blow or fall to bend them inward, seeks a bending moment. In the older typ of flier body part a bar was forged with a thickened (3611-- tral part (to form the connection) and with its extremities (to form the legs) thin but rolled into slitted-tubular form, and it consequently had the disadvantages already alluded to. By using sheet metal and forming the body part as described I obtain without special operations, such as those incident to forging, not only great strength but a proper distribution of metal for both balance and, to a certain extent, finish and I am able to reduce the costof manufacture very considerably.

The flier head is shown at it. It is as usual tubular and has two lateral and opposite eyes it for receiving the roving, which it will be understood is threaded down through one eye it, the corresponding leg d and its eye f, being entered into the leg by its slit d. The head should be secured to the body part in some substantial way and in View of the thinness of the material of the body part I provide an elongated block 2' which is arranged in the channeled connection c and in crosssection fits the same (Fig. 4) so that it is thus confined against lateral movement, being also held against longitudinal displacement by some suitable means as rivets j, incidentally, the ends of the block are bevelled, as at i, so as to eliminate any recesses that might otherwise be left for lodgment of fibres of the roving. The block has central hole 2' registering with hole 6. A screw 70, entered through and fitting the aperture formed by e i" in the support for it thus formed by e and i, is screwed tronbelow up into the head, which is seated in tlie channel of the connection 6 upon the block a. The screw may be held against loosening by a rivet Z; it is as usual tubular to receive the upper end of the spindle on which the flier when in operation is placed.

The construction in F 7 is substantially the same as that already described except that the block, m, bears against the under side of the connection 6, the screw, 3), bearing here against the block and holding the head, 0, bearing directly against the connection,

seated as before in its channel. The block is shown held against lateral displacement. by being longitudinally grooved, as indicated at m, to receive and fit the convex under side of the connection, and it is held against longitudinal displacement by suitable means, screws nbeing shown.

in each construction the I head-including structure formed in the present examples by the parts it, 2', is, or 0, m, p has a rigid elongated portion or m) which, by extending lengthwise of the connection part of the flier body, atlords solid support for said structure and reinforces said connection part.

If desired, a portion of the connection 6 may be cut away, as shown at g in Fig. 6 by dotted lines, to afiiord the attendant increased finger room in threading the flier.
