SPINNING MACHINE

Application May 1, 1937, Serial _No. 140,094
6 Claims. . (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
