To (Il/IZ '1o/'20171. it wi f1.1/ concern.' Be it known that l, tiAirn MnnooLiUs, s citizen ot the United States, und e resident. of Richmond` in thc county oi yllenrico and State of Virginia, have inrented certain new and useful improrements iu ivlethods ot Restoring or llejuvenating;l Bale-Tie Bands. of which the following is a specification, This invention relates to u process for treating or reworking old or used tie-bsnds employed on cotton bales or the like. The tie-bands employed on billes of cotton are manufactured in standard lengths. usually eleven and one-half 'feet when used in conjunction with soft bales. @n compressed bales, the length is usually reduced to eifzht and one-hulll feet. uWhen the cotton or other .materiel in the bale is to be taken therefrom, the tie-bands ure cut or severed land the pieces or 'fragments of the tie-bauds are discarded, being regarded ss u miste product. lt is truc that. heretofore, it has been proposed to torni tie-hands of tivo or more pieces riveted together but such so culled piecedi tie bands have been 'found unsetW istsctory generally and in some States their use has been prohibited by inw. ln the fece of these objections the use ot the pieces or fragments ot' old tie-bends, that issot those which have been cut or severed in taking the cotton from the bale is impracticable und entirely inexpedient. The object oi' the present invention is to provide :L process for trentineY or reworking these pieces of old or used fragments to pro- (luce one-piece :ind integral tie bands of stsndsrd length and of requisite. tensile strength so that the tie-bands produced by the process are in all respects conformable to the law and es highly adapted to perform their functions as the. original tie bands of which they had been port. Another object is to provide a process ot this 'character which is inexpensive `and. which may be Carried out with instrumentslities'resdily :available and without the employment of skilled operators. iin cerrying out the process, the longer pieces or fragments' alone are utilized, the short pieces being; discarded. Ordinarily pieces less than five feet in length iare not used. The selected pieces are iirst subjected to s picliling-hsth ond for this purposetliey are immersed in e vat or tank cont-:lining n piclrling solution lot any standard composi tiorn the picklingvbsolution usually consisting of sulphuric or hydrochloric acid. The piel;- lingl solution cleenses the surfaces 01"' -the pieces and removes sil paint or costingf7 Well es all rust, seele. dirt or other foreign matter ond all adhering bres of cotton or the like. Thus the pieces of the tie-bends present in their entirety, clean, ineteliic sur feces. After having been thus treated, the pieces ot the tie bands are annealed. Thesnnesling gives to pieces the requisite softness and' eliminates all brittleness or brittle 'or strained spots. Further, and what is regarded :is most important, 'thev annealing gives to the metal composing the pieces the property or capacity ot taking gloss or finish in the final loperation, feature which. is essentiel to the complete rehabilitation or" the tie bands for trede purposes. Any stond ard method oinnneziling adopted to this character of nietsl and to the structure of. the tie-bands may be availed ot and any conventional apparatus used inI conjunction with annealing inziy he employed. i The linal step in the proc consists in cold rolling the annealed pieces to elongate them in order to produce tic-bends ot stand ard length :rnd ot requisite tensile strength. The apparatus employed is the conventioneel apparatus for cold rolling' steel but it should operate only to elongate the metal or". the pieces and should not he perinittedcr be such as to Widen the bends. The elongation is o'f course et the expense oi the ot the nietsl but the gauge nietsl making up the originel tie-bsnds is :imple to permit of reduction Without decreasing the tensile strength below the required point or degree. lt has been mentioned tiret the cold rolling f 'must .be carried outso es to elongate sione and so es not to Widen the bands.. ln order to illustrate this operation it ins-y be said. that one oit the rolls of the apparatus may be formed with s plurality of spaced circuinferentiaily extending grooves and the other roll with spaced oircuniferentielly extending annular ribs fitting onto or running in seid grooves, the side edges of the tiebunds or the pieces tliereoiljeing subjected to the cold rolling` operation shutting the ribs whereby interni spreading: or widening is prevented. it is to be understood howm ever that the invention is not to be restrict ed to any torni of apparatus and that theA .1 construction of solis referred to is instsnee-ti merely tor the sii-lie oit iiliistrstion. When the cold rolling operation has heen completed, the pieces have been reworked or ormed into tie-hands oli substantially standard dimensions and of strength. over they have the smoothness. iinish and gloss which gives to them the appearance necessary for their complete rehabilitation for trade purposes. In the preferred Inode of practicing the process, the sequence of the steps or phases is as has heen described but it is to he understood that. itl desired` the cold rolling of the pieces may follow their treatment' with the pickling solution and the annealing ma): constitute the final step and in this event of course follows. the cold rolling. Should it be desirable the tie-hands thus produced may he suitably 'tempered and also may he cut to standard length should they he in excess thereof. Although any conventional or desired form of apparatus may he utilized .tor carrying out the process and t'or producing the reworked tic-hand, it is thought liest for the sake of illustration to show ,generally and diagramniatically one form oiI apparatus hy which the process may he earried out and the article produced. Accord ingly, reference had to the accompanying drawings forming a part ot this specification, and in which: Figure l is a view, partly inelevation and partly in section.y showing diagrammatically and generally the type ot' apparatus which may he employed; and Figure 2 is a view. in elevation. showing one form or type of rolling apparatus ior carrying out the cold rolling ot the pieces. Referring to the drawing", the numeral l() designates diagrannnatically a pickling tank or vat which contains the pickling solution and wherein the pieces or fragments of the used tie-hands are immersed wherehy the rust or oxidation and all scale7 dirt, foreign matter, paint or coating and adher ing fibre are removed. The apparatus 'for carrying out the annealing is shown diagramrnatically and for the sake of illus tration as comprising an annealing .Furnace 11. From the annealing tui-nace the pieces are conveyed in any suitable manner to the cold rolling apparatus designated generally at 12. The cold rolling apparatus may he of any conventional or desired type and as shown in Figures i and 2 it- .may comprise a pair of standards or pedestals i3 mounted upon a suitable hase and in which the rolls le and 15 are rotatably mounted. The rolls are constrained to partake o' proper motion h v means ot' twin gears l5 and are driven trom any source of power. As previouslyY indicated it may lie desirable to provide some means 'for preventing widening or spreading of the pieces during the cold rolling operation, and one manner in which this may he done is shown in Fignre and consists in providing the roll la with a plurality ot circumt'erentially extending annular grooves ll" in which Circuin't'erentially extending annular ribs or flanges 15 l'ormed on the roll l5 run or inter-tit. the pieces having their side edges abutting the flanges or rih during the operation in order to prevent widening or spreading. (inviously, many other mechanical expedients will suggest themselves to persons skilled in the art and are eomp'rehended within the spirit and scope of the present invention and of the appended claims. lt is to he understood that if desired the pieces may he cold rolled in such a manner as .to permit slight widening thereof. in this event the rihs and grooves of the rollers may be omitted. (')t course even though the pieces were slightly widened 'they would he in the main elongated. The widened or elongated hands thus formed will he well adapted for a variety ot' uses such as on India haies or as hoops for 1barrels or the like. "While it is to he understood that the larger pieces are utilized for producing a reworked or rejuvenated tie hand, the small pieces may he utilized tor the production of hoops for around kegs as well as for other purposes. l claim: l. rThe herein-described process of converting the pieces ot used tic-hands into standard tie-handswhich consists in suhjecting the .pieces to a piekling hath. suhsequent'ly annealing the pieces and in cold rolling the pieces in such manner as to elongate them while maintaining their width. 2. The herein-descrihed process of reworking the pieces of used tie-hands or the like which consists in annealing the pieces 'and cold rolling the pieces to elongate them. C. The herein-described process of con verting the pieces ot' used tie. bands into standard tie-hands which consists in coid rolling the pieces in suohmanner as to elongate them while maintaining their width. t. The herein-described process of reworking the pieces ot' used tie-hands or the like which consists in subjecting the pieces to a piclzling hath7 annealing `the pieces`r and eoid rolling the pieces to elongate them.
