BUNCH BUILDER FOR SPINNING MULES
‘Carl J. Paolucci, Millbury, Mass, assignor of one
half to Richard K. Mitchell, Millbury, Mass.
Application October 28, 1937, Serial No. 171,583
6 Claims.
The present invention relates to new and useful
improvements in bunch builders for spinning
mules and has for one of its important objects to
provide, in a manner as hereinafter set forth, a
5 device of this character embodying a construction
and arrangement which is such that a compara
tively short, uniform wind will be made when
forming the bunch and, further, which will cause
the bunch to be formed at the very bottom of the
bobbin.
Another very important object of the invention
an operating lever or handle 5.
'
Fixed at spaced points on the rear end portion
of the shaft 4 are substantially angular metallic ~ 1
arms 6. Fixed on the free ends of the arms 6 and
engageable on top of the rail 2 is a metallic builder
bar ‘I which constitutes the most important part
of the present invention.
As illustrated to advantage in Fig. 2 of the 10
drawings, the top of the builder bar 1 slopes from
is to provide a bunch builder of the aforemen
the rear end thereof toward the forward end to a
comparatively abrupt portion 8 and terminates in
Still another important object of the invention
is to provide a bunch builder of the character
described embodying novel means whereby the
device may be conveniently positioned on the
20 builder rail of the mule for operation and removed
therefrom after the bunch has been formed.
Other objects of the invention are to provide a
bunch builder of the character described which
will be comparatively simple in construction,
strong, durable, highly e?icient and reliable in
use, compact and which may be manufactured at
low cost.
All of the foregoing and still further objects
and advantages of the invention will become
apparent from a study of the following speci?ca
tion, taken in connection with the accompanying
drawings wherein like‘ characters of reference
designate corresponding parts throughout the
several views, and wherein:
Figure 1 is a perspective View, showing a bunch
builder constructed in accordance with the pres
ent invention mounted in position and ready for
use on the builder rail of a spinning mule.
Figure 2 is a view in side elevation of the inven
40
ence numeral 3. Journalled in the bearings I is
a shaft 4 having ?xed on its forward end portion
tioned character which may be expeditiously in
stalled on a conventional mule without the neces
15 sity of materially altering same structurally.

tion.
'
Figure 3 is a view in cross section, taken sub
stantially on the line 3—3 of Fig. 2.
Figure 4 is a cross sectional view substantially
similar to Fig. 3 but showing the bunch builder
45 disengaged from the rail.
Figure 5 is a view of a bobbin having thereon a
bunch formed with a builder in accordance with
the present invention.
Referring now to the drawings in detail, it will
be seen that the embodiment of the invention
which has been illustrated comprises a plurality
of bearings l which are ?xed in any suitable man
ner at longitudinally spaced points on one side of
the usual builder rail 2 of a conventional spinning
mule which is designated generally by the refer
a point in a manner to facilitate the mounting
thereon from the rail 2 of the usual wheel of the 15
builder mechanism of the mule. Further, the
builder bar 1 has formed therein a plurality of
arcuate recesses or dips 9 which, as will be readily
apparent, cause the aforementioned wheel It (see
Fig. 1) to rise and fall. The bar ‘I may be posi 20
tioned as desired on the rail 2 by adjusting the
shaft 4 longitudinally in the bearings l.
Movable
collars I l are provided on the shaft 4 on opposite
sides of one of the bearings l for securing said
shaft in adjusted position.
25
The construction and arrangement of the bar ‘I
is such as to make a short, uniform wind on the
bobbin when forming the bunch.
Further, the
bunch will be formed on the lowermost portion of
the bobbin. To engage the builder bar 1 on the
builder rail 2 of the mule for use, it is only neces
sary to rock the shaft 4 in one direction through
the medium of the handle or lever 5. Of course,
when the shaft 4 is rocked in the opposite direc
tion the builder bar 1 is swung to inoperative 35
position, as seen in Fig. 4 of the drawings. Fig. 5
of the drawings illustrates a bobbin l4 having a
comparatively short, uniformly wound bunch l5
formed thereon by the device constituting the
present invention.
40
It is believed that the many advantages of a
bunch builder constructed in accordance with the
present invention will be readily understood and
although a preferred embodiment of the device is
as illustrated and described, it is to be understood 45
that changes in the details of construction and in
the combination and arrangement of parts may
be resorted to which will fall within the scope of
the invention as claimed.
What is claimed is:
5.0
1. A bunch builder of the class described com
prising a rockable shaft, and a builder bar
mounted on said shaft and engageable with the
builder rail of a spinning mule, said shaft sub
stantially paralleling the builder rail, said bar 55

having a plurality of substantially arcuate re
cesses therein.
2. A bunch builder of the class described com
prising a rockable shaft, means for actuating said
shaft, arms ?xed on the shaft, and a builder bar
?xed on said arms and engageable on the builder
rail of a spinning mule, said shaft substantially
paralleling the builder rail, said bar having a plu
rality of substantially arcuate recesses therein.
10. ‘3. A bunch builder of the class describedcom
prising a plurality of bearings, a rockable shaft
journalled in said bearings, means for actuating
said shaft, a plurality of arms ?xed on the shaft,
and a builder bar ?xed on said arms and engage
16 able on the builder rail of a spinning mule, said
shaft substantially paralleling the builder raiLthe
top of said builder bar sloping from one end
toward its other end and having formed therein a
plurality of substantially arcuate dips.
_
20 4. In a spinning mule including a, builder rail, a
plurality of bearings on one side of said builder
rail, a shaft rotatably and slidably mounted in
said bearings, adjustable means on said shaft on
opposite sides of one of the bearings for securing
g; the shaft against longitudinal movement in the
bearings, an operating handle ?xed on one end
portion of the shaft, a plurality of arms ?xed on
the shaft, and a builder bar ?xed on said arms and
engageable on the builder rail of the mule.
> 5. Ina spinning mule including a builder rail, a’
plurality of bearings on one side of said builder
rail, a shaft rotatably and slidably mounted in
said bearings, adjustable means on said shaft on
opposite sides of one of the bearings for securing
the shaft against longitudinal movement in the 10
bearings, an operating handle ?xed on one end
portion of the shaft, a plurality of arms ?xed on
the shaft, and abuilder bar ?xed on said arms and
engageable on the builder rail of the mule, the top
of said builder bar sloping from its rear end 16
toward its front end and having formed therein a
plurality of substantially arcuate dips.
6. In a spinning mule including a builder rail, a
shaft journalled on said builder rail substantially
in parallelism therewith, means for manually 20
actuating said shaft, and a‘builder bar mounted
