ATTORNEYS United States Pat Y FLYER Elvin B. Robinson, Gastonia, N. C., assigner to Ideal Industries, Inc., Bessemer City, N. C., a corporation of North Carolina Application April 7, 1955, Serial No. 499,863 12 Claims. (Cl. 'S7-117) method of making same in which the inverted U-shaped body which carries the yarn depositing mechanism or presser is made of a piece of metal tubing with the pilot member thereof, for axing the same to the spindle, being made of another piece of metal suitably secured to the flyer, as by a pressed fit.

It is another object of this invention to provide a flyer having the inverted U-shaped member or body made of a piece of tubing with the leg of the body accommodating the depositing mechanism or presser being of smaller diameter or tapered so that, when the depositing mechanism is added thereto, the ilyer will be in perfectly balanced condition.

It is another object of this invention to provide a'yer made of a piece of tubing with the presser attached thereto` and in .perfectly balanced condition with the central portion of the liyer being made of a separate piece securely mounted on the tubing.

Someof the objects of the invention having been stated,

`other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which- `Figure l is a side elevation of the improved yer in association with parts of a roving frame shown somewhat A upper central portion of the flyer shown in Figure l,

and looking `along line 7-7 in Figure 4, but omitting the spindle.

In the drawings 'the numerals 1t) and "11 indicate the front rollsof a roving frame or slubber while 12 and 13 indicate the middle rolls. A'roving frame has other rolls, all which is common to the art. The improved flyer is adapted to .be used instead of the conventional `flyer and. is used on apparatus such as shown in U. S.

PatentNo. 2,046,376 of July 7, 179316, issued-to P, A. Gwaltney et al. i

j The rolls 10-13 are mountedin suitable rol] standsllS i and a` strand of roving or sliver S passes `throughfthe n .rolls and is attenuated and moves into the improved ilflyer, the body of `which is broadly designated at 16.` `The flyer works on a `spindle 17` which 1is driven by any` t 2,873,571 Patented Feb. 17, 1959 suitable means, such as shown in said patent, in a right to left direction and the flyer rests on top of the spindle 1,7 while the spool or bobbin 18 is driven by a suitable whorl 19 in the same direciton as, but at a lesser rate of speed than the flyer.

The flyer body 16 is an inverted U-shaped tubular member, preferably made from stainless steel, with the central portion or pilot member 2t) thereof made of a separate piece but Welded or otherwise secured to the tubular member 16. The pilot member 20 is aiXed, as by a pressed lt, to the U-shaped member 16 or by any other suitable means such as being slid over one of the legs of the flyer and axed in central position. The flyer body 16 has

legs

22 and 23, part of the leg 22 being of lesser diameter than the leg 23 or being tapered so as to give the leg 22 lighter weight to compensate for a presser assembly 2d loosely mounted thereon.

The tubular pilot member 26 has a slightly tapered bore 25 therein for receiving the slightly tapered upper end portion of spindle 17. The tubular pilot member 2t) has a transverse pin 47 therethrough which s adapted to ht into a notch d8 in the upper end of the spindle 17. The presser assembly 24 is similar in all respects to that shown more clearly in said patent.

The leg 22 has a slot 26 running its entire length and up to the point where the member Ztl is axed thereto. The slot 26 runs to the eXtreme free end of theleg 22 and is in open position before the bobbin is started `but when the bohbin is filled partially or fully the lower end of the presser assembly closes the slot 26.

The pilot portion 2t) has a square breached hole 30 which extends downwardly and communicates with the enlarged tapered bore 25 in the lower portion of mem# ber 20. After the flyer 16 is fixed in position, this closes the lower end of hole 3l) and the tubular body 16 has an opening or aperture 31`therein which communicates with the upper portion of the square hole 3l). The yer body 16 also has an opening 33 in its side which communicates with an enlarged tapered bore 34 in the pilot member 2li and the strand S passes downwardly through the

bores

30, 31 and longitudinally through the leg 22 i of the body 16. The roving S passes out of the bottom It will also be noted that the leg 22 has a pluralityof bores 36 therein to prevent suction from having any effect on same. The leg 22 is recessed and has a tting 40 mounted in the same which accommodates one end 41 of the presser assembly 24 and the presser assembly has a vertical body portion indicated at 43 whose lower end has a rounded member 45 thereon to which one end of the presser foot 35 is connected. The rounded member 45 is cut away to permit threading of the strand S into the slot 26, preferably, when the bobbin 18 is empty. p

Heretofore, flyers have been cast or forged of a single piece, with the exception of the presser assembly, and the subsequent forming and finishing operations required to balance the conventional flyer have been such that the flyer has been expensive to produce V,as compared to the present yer. Also, the useful life of the `conventional type of yerhas been limited due to ballooning ofthe legs thereof by centrifugal force. This is overcome in l 3 Another outstanding feature of the improved flyer disclosed herein resides in the fact that the tubular body 16 is of the same internal diameter throughout its length Ythereby permitting' polishing of the interior wall of the vbody 16 throughout its length with a polishing tool of corresponding size. Conventional flyers are provided with a funnel-like leg through which the roving passes in its course to the presser foot and the shape of this funnellike leg has made it practically impossible to smoothly polish its interior surfaces.

It is seen that l have provided a flyer made of two separate pieces and suitably secured together so that the expensive method of making a flyer such as shown in said patent is eliminated and a perfectly balanced yer is made out of two pieces of separate material fixed together. The roving S may also be threaded into the lower end of a slot 26, through the leg 22 and then through the bore 34 and through opening 33 and through the central portion of member 16 and up through the broached bore 30 and between the rolls of the roving frame.

In the drawings and specitication there has been set forth a preferred embodiment of the invention, and although speciiic terms have been employed they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.
