(011424-139) In the ordinary worsted spinning machine, given the active roving or supply spools, the spin ning units below and forward of such spools and the drawing and retaining rolls between the rov 5 ing spools and the spinning units (the retain ing rolls being usually adjustable toward and from the drawing rolls), the reserve or empty spools which are to replace those on the spindles of the spinning units when the latter spools are 10 ?lled and doffed are usually supported on pegs o-r skewers pivoted on'the respective retaining ' In the drawings, Fig. 1 is an elevation of so much of one side of a worsted spinning machine as includes and is pertinent-to this invention; and > ' Fig. 2 vis-a ‘sectional view on line 2-2, Fig. l. The ?xed structure of the machine includes the usual stand or rack l to support on pegs 2 and thereby hold in upstanding positions the row of active roving spools or equivalent yarn sup plies '3 and extending above such rack the up- I rights, such as 4, whichcarry the rack 5 for the roll assemblies so that they can be shifted to a reserve of ?lled'roving spools or equivalent yarn more or less forwardly projecting position for supplies 6. The active receiving spools, the spin dles-inclugling spinning units on whose spindles such spools are mounted, such spinning units removing the spools therefrom and placing fresh 15 empties thereon or to a position in which they project rearwardly and toward the active roving spools, out of the way. Latter-1y, the receiving being arranged ‘s at lalower level than the rack ' spools are being formed longer than heretofore between each roving spool and the corresponding so as to- have greater’ capacity, the consequence 20 of which is that when these spools are in their spinning unit, are not shown as not material but may be according to the usual construction. The retracted or back positions they extend too closely to the active roving spools.‘ The object of this-invention is to provide for empty receiving spools or equivalent yarn sup» supporting these reserve receiving spools, what 25 ever their length, so that they will be in conven ient reach of the attendant and need not in any way interfere with the spinning operation or be in the way of the attendant in such duties as may be necessary to that operation. To» this end I 30 have provided a rack to support the row of such spools and which overhangs the row of roving spools but may be pushed back transversely of such row and out of overhanging relation there to when the roving spools require to bedoffed This rack desirably is movable‘from its overhanging rela tion to the roving spools back and upwardly, pref erably having arcuately arched portions and be ing suitably guidedin the ?xed structure of the 35 and replaced by freshly ?lled ones.
