FLIER CONSTRUCTION Filed Feb. 20, 19355v SMQ/who@ Jam/Mmm@ GMM/wang Patented Sept. 11, 19134 11 Claims.

adapted for use with the hier block disclosed herein and also of general application in connection With iiier blocks having a peripheral Wire receiving groove.

En my application Serial No. M4554, filed Sept. 193i, there is disclosed a removable foot for ilier blocks wherein the foot is attached to the block by means of a suitable bushing or sleeve. In my application, Serial No. 554,312, tiled July 31,

931, l have disclosed an improved pre-formed iiier Wire and securing means therefor. The present invention is an improvement over the disclosures oi the above mentioned applications.

An object of my invention is to provide an improved flier blocl; having a removable foot.

Another object of my invention to provide a novel foot structure adapted to be attached to iiier blocks o the type designed to be locked to a hobbin by inea-ns of a flange or foo-t formed on the hier block.

`Yet another object of my invention is to provide a pre-ior'ned Wire construction, in Which the wire itself forms, locking means whereby the iier vvire is fastened to the block.

Still ano-ther object oi my invention is the provision oi impro-ved Wire constructions which are adapted for mutual interlocking.

With these and other objects in View, which may be incident to my improvements, the invention consists in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements, comprising my invention, may be varied in construction, proportions and arrangement, without departing from the spirit and scope oi the appended claims.

in order to make my invention more clearly understood, 1 have shown in the accompanying drawing means for carrying the saine into practical eiiect, without limiting the improvements in their useful applications to the particular constructions, which for the purpose oi explanation, have been made the subject oi illustration.

In the drawing, like numerals refer to similar parts throughout the several views, of which Figure 1 is an elevational view partly in vertical section of bobbin mounted upon a spindle and provided With a flier block and associated retaining bushing.

Fig. 2 is a perspective View of an improved ilier block showing the removable foot in position on the block.

Fig. 3 is a sectional view along line 3--3 oi Fig. l.

Fig. 4 is a perspective vievv of an improved preformed Wire.

Referring to the drawing and more particularly to Fig.

mounted upc le 2, having an upper section 3, which 1s adapted to support a freely rotataele r r block Il. The hobbin is also provided with the usual bushing 5 mounted in the opening 6 formed in the upper end thereof. The nier block 4 has a central aperture rI and is provided with a peripheral Wire receiving groove 8 into which the improved hier wire 9 is iitted. The block is further provided with a peripheral groove l0 adapted to receive the ioot member 1l, and is tapered at il to facilitate positioning of the foot in the groove.

Referring to Fig. 3, the novel foot inember 11 is substantially pear-shaped and is formed from a single piece oi Wire, shaped to conform with the groove l0. Wire from which the foot is made may be of steel or other suitably hardened material of the character adapted to retain the desired shape during the operation oi the flier.

The foot member is provided with an extension 12, eccentric with respect to the iiier block, adapted to engage with the bobbin bushing 5 and lock the hier to the bobbin. In attaching the eccentric foot to the iiier block, the vvire is sprung a sufficient amount to enable it to slip over the end of the block, and seat in the groove l0. Since the foot member is :formed of material which may be tensioned to give the desired spring effect, the wire will be retained in the groove during the normal operation of the device. It will be noted that the Wire forming the foot is not continuous and the ends 13, 14. may be sprung apart to enable the wire to pass over the lower end of the block. Y

While I have shown my improved eccentric foot in combination with a block designed particularly for this type of ioot, it will be apparent that the improved foot is adaptable for use with conventional iier blocks.

"in certain of the prior art devices, an eccentric foot formed integral with the body of the block is used. It has also been proposed to use blocks having projections of various kinds to form a foot adapted to engage with the bobbin bushing. In these devices, during the rotation of the bobbin, the block oscillates or rotates and the eccentric foot bears .against the under side of the bobbin bushing and is rapidly Worn down due to the comparatively small area oi bearing surface. Since the eccentric foot is formed integral With the body of the block, the block must be replaced after the foot has Worn away.

With my improved flier foot, it is possible to reclaim and use blocks which are initially provided with an integral foot or oppositely disposed flanges adapted for insertion into bobbins. It will be appreciated that the body of the block proper together With the Wire receiving means i, there is disclosed a bobbin l,

is generally in condition for further use alter the eccentric foot has Worn away.

In order to equip the discarded blocks with iny improved foot, part of the original eccentric ,toot or flange is cut away, leaving the body ci the block of uniform diameter. A. eripheral groove is then formed in the body of the block near the lower end thereof, and a foot inern'oer of the type disclosed, iitted into the groove. blocks may then be applied to bobbins andare in condition for further use.

It is to be noted that the eccentric ioct or ilanged foot inernber oi conventional flier blocks, is made of the saine material as the blocks, neually brass. Since the bol-coin bushings are of steel or other hard material, the foot member Wears away rapidly with the resu.t the block must be replaced. My irnpr ved flier foot inember is made ci steel or material equally as hard as the material from which the bobbin bushing is made and therefore will last longer under actual Working conditions, than the conventional brass foot. When, after a continued period of use, the foot begins to Wear, it may be readily replaced, thus effecting economies in maintenance oi such installations.

Referring to Fig. Ll, I have shown an improved preformed wire adaptel for use with the hier block disclosed herein and or general application to flier blocks having a wire re eiving groove. The nier Wire comprises a single piece of Wire having a drop arrn l5, and str ight arnis 16 together with the usual eyelets 17 iorncd at the ends or the respective The flier 'ire is provided With a central block engaging section 18 adapted to it into a peripheral groove formed in the block. At either side oi the central block engaging sections, oiisct portions 2) are provided. It Will be noted that these onset portions are substantially ill-shape formation and so designed to engage with each other and loci: the wire to the block aiter the Wire is positioned in the peripheral Wire receiving groove.

The manner in which the wire is attached to a :filler block is shown in Fig. l. T1 e cernL l block engaging section 1S seats the groove 8 arms 16 twisted or entwined so as to bring the oset portions 20 into muto. engage ent and fasten the wire to the block. y providing a preformed Wire accor-ding to the present construction, it is unnecessary to use means other than the Wire itself to securely ias-ten the wire to the block. 1t will be noted that when the block and Wire is in the operative position on a spindle, that the arms ci the vfire extend outwardly irorn the block in a direction opposite to the eccentric foot. This arrangement is for the purpose oi providing a balanced condition of the parts during normal operation of the device. 1n Fig. a, it will be seen that the eccentric foot lf2, nts under the ilange of the bobbin bushing 5, securely locks the nier to the bobbin.

It will be understood that the Wires may be formed with oset portions of various diierent congurations and arranged for mutual engagement with each other when the arins are in twisted relation. The basic concept of rny invention, however, is the provision of a self-locking flier Wire without reference to the specific details of the oiset portions or central bloeit engaging section. 1t will be appreciated that While the sel" locking wire is associated with a particular forni of block, that the Wire can be used with other blocks having a peripheral Wire receiving groove.
