PATENTO FFICE f V `MICHAEL J. MCHALE, oF scRAN'roN, PENNSYLVANIA ,Y FLYER CONSTRUCTION Agpiicati'on filednay 31,

This invention relatesto- -iyers for spin` ning machines and; more particularly to one having .completely replaceable parts.

\ Hitherto it has been pro-posed to use `flyer passing therethrough. In addition,mill nuts or'` other like devices areoften required to hold the i'ye'r blocks in place on the spindles. Where selfcontaine 3lf` springs held in place l5 by bushings have 4been used, thedisadvantage of' the mrllnut has been obviated but the re-Wiring of such devices is, in every instance, a customjob;` Where devices of the typev shown in the patent to' E. Herr 2U #l,6l4,552 have been-used, vconsiderable dificulty has been experiencedl withthe maintenance and repair ofthese devices, dneto thefact 1that'special tools Vare required for the assembling steps, ink order to removeV broken' wires and replace them with new ones, and, in addition, the. expansion anchoring sleeves frequently break and cannot be replaced, thus requiring scrapping of the entirre unit.

Y y lit is an objectV of the `present, inventi'onto pro-vide a `iyer for spinning purposes which is composed of -aplurality ofv replaceable parts.-

It is anotherobject-ofv this invention to-v provide; an. improvedflyer ofthe ltype described whichi's freely movable and pro videduwith replaceable' parts throughout. 1

H Yet `another object of this invention. isi the` provision of la novel flyerl construction v 40 in which lthe flyer wires orI arms serve as a Vlocking means. n

ItV isalso an object Vof this. inventionto novide agiyer which canbe readily assein` led-.and disassembledi and which cann'otbe V placed in. operation until? thev several parts are. respectively placed intheir correct loperatingzposit'ions'.

vReferring now tothe drawings, there'k is shown aconventional spooly or bobbin: 1. mounted on a spindle 2. The novel flyer of the presenti invention, designated genera/lily as. 3,. is. mounted on the `spindle. and attached. thereto'Y by mean-sof springl member 4 whose. function will beaverted to more in :detail hereinafter. The flyer body of the member v 3 is preferably made of .any suitable metal such as brass, bronze or the like, the' several parts being machined-to shape or otherwise formed and comprises an upper portion. 5 and a lower portionV 6L Member 5 comprises a cylindrical body portion having a `Centrall aperture 7 provided with ashoul'der portion n 8 adapted to retain spring member 4 in place.

The member 5 is provided with'flanges 9,1'0, the latter being adapted to 'abut` against shoulder 11 ofmember 6. In addition, meinber 5 is provided with a threaded extension 12, adapted toengage a corresponding female thread 133 in member y6.

The member 6 is provided with a central aperture 14 and an internally shouldered portion 15 adapted to serve as a stop for member 5 when screwed in place. Integral with portion 11, the socket or casingA member 6 is provided with an annular extension 16 adapted to receive flange 10 of member 5. In addition, member-1G is provided with a plurality of diametrically positioned slots 17 having laterally extending portions 18 adapted to receive sections 21 of flyer wires 20 and hold them in position. lVhile the apertures 18 have been shown as substantially horizontal they may of course be given any desired configuration as shown at 19 in Fig. 8' in which they are slanted downwardly and inwardly from the aperture or slot The flyer wires 2O are provided with a central semicircular bowed portion 22adapted to engage or abut against section 7 ot the fiyer holder and Vis further adapted to be locked in position in the apertures 18 and/or 19. The flyer wires may be inserted in position by passing the bowed portion 22 into the Y gap or space 23 formed between the abutting parts 5 and G of the flyerblock. After passing the bowed portion in this manner, a portion 21 of the wire is forced into engagement with section 18 of the retaining slots and the opposite section 21 of the same wire is forced into corresponding engagement with a like slot member. It will be seen that the leverage aiorded by the bearing of the portion 22 against the member 7 and of section 21 against portion. 16 of the cooperating part ofy the flyer device will maintain the members locked together due to the fact that the flyer, wire engaging flange 10 will prevent the unscrewing of the parts, thus serving as a. key or locking member.

When it is desired to unscrew the parts of the liyer block for any reason it will be sufficient to force both of the flyer arms out of engagement with their respective sockets and upwardly into slot 17 and out through aperture 23. As intimated hereinabove, a plurality of iyer wires may be applied, as is indicated in Fig. 4. In this instance, it is merely necessary to provide the slot 17 in member`16 with oppositely positioned' depressions or reentrant portions 18,19. rIhe flyer wires are providedrwith the usual eyes 24, formed at the end of the depending sections 25 of members 20. Owing to the fact that flyer wires wear out at the eyelet portions only under normal working conditions due to the abrasive action of the threads, the present invention.comprehends the idea of providing such sections of the flyer wires with a coating of an abrasion resisting metal such as chromium metal or the flyer wires may be formed of a potentially hardenable metal which is manipulated and formed in the 1 usual manner after which the sections 24 may be subjected to any desired treatment whereby to give them a differential hardness.

Referring now to the spring members 4, 1t will be noted that they are freely movable within the central portion of the flyer block and are held from axial movement by the shoulders 8 and 15 of the block. The spring member 4, Vas above indicated, is adapted to engage spindle 2 and revolve therewith the section 7 of the flyer block serving as a bushing or cage upon which the fiyer and itsassociated wires are adapted to freely revolve about the member 4.

While a spiral spring construction may be used, the invention also comprehends the use of a coiled flat spring of the general type shown in Fig. 9. This construction comprises a coiled spring 26havinga centrally offset portion 27, adapted to receive the ends 28, 29 of the spring and present a uniform internal and external diameter. q

It will now be appreciated that there vhas been provided an improved flyer construction comprising a plurality of mutually interlocking parts which are severally replaceable at will and which are characterized by ahigh degree of mechanical efficiency as well as comparative ease Aof manufacture and replacement. In addition, there has been provided an improved flyer wire having a Wear resistant section at the point where normal break down, due to abrasion occurs.

In accordance with the provisions of the patent statutes, Ihave described the principles of operation of my invention, together with the device which VI now consider to represent a preferred embodiment thereof;.but I desire to have it understood that the device shown is only illustrative of the basic concept of the present invention, and that the said invention may be carried'out by other means.
