Improved Means of Supporting Bobbins or Spools, applicable to
Winding Frames and Carding Engines, and to Mules or Spinning
Frames.
I, CHARLES AUBREY DAY, Chartered Patent Agent, of 321, High Holborn,
in the County of London, do hereby declare the nature of the said invention, and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The object of this invention is to prevent the slubbing as it is wound upon a
spool, from packing and compressing. The invention is not only applicable to
winding frames and carding engines, but is also applicable to mules or spinning
frames where the slubbing is unwound from the spool. Heretofore, both in winding
the slubbing upon and unwinding it from the spool, the weight of the spool itself
was carried by the slubbing on the spool; consequently as the spool increased in
size, the weight became greater, and, consequently, the pressure was such that in
many cases when the slubbing was unwound from the spool it would pull apart at
frequent intervals causing much delay, and the thread spun from the slubbing was
not of the finest quality.
In the accompanying drawings-
Figs. 1, and 2, are side views of a spool frame or creel adapted to be placed in
front of a carding engine or spooling machine. The lower tier of spools only are
shown, but it will be understood that two or more tiers may be used without
departing from the invention.
Fig. 3 is a front elevation of the lower part of the spool-frame shown in Fig. 1 ;
and
Fig. 4, is a view of a modification of the invention.
A, represents the two side frames tied together in any suitable manner. Pro-
jecting from each frame are arms B, on which is supported the driving drum C, and
the spool D. The shaft c, of the driving drum is mounted in suitable bearings b,
on the arms. The spool D, has flanges d, and a bobbin portion d', between the
flanges, and projecting from each end of the spool is a journal d². These journals
rest, in the present instance, on curved portions a, of the arms, although, in some
instances, the arms may be perfectly straight.
The spool is supported by the arms and is pressed against the drum C, by two
levers E, in the present instance, hung to the side frames at e, and attached to each
of these levers is a rope or cord f, which passes over a sheave f¹, and suspended
from this cord is a weight F. This weight may be made in sections so that it can
be regulated to regulate the pressure of a spool upon the drum; one weight may be
used where the two arms are connected.
A spring may be used in some instances in place of the weight without departing
from the invention. The spring may be attached as shown in Fig. 4.
The object of curving the face a, of the arms on which the spools rest is to
utilize part of the weight of the spool so that the lever pressure need not be so
great. The arms are so curved that when the spool is small, and consequently
light, the incline is greater; thus the spool is forced against the drum, but as the
arm recedes from the drum the incline becomes less, and the greater proportion of
the weight of the spool is sustained by the arm, the minor portion of the weight
taken by the drum is about the same as the pressure taken by the drum when the

page_text: spool is empty. In some instances, this curved surface alone may be used without
the lever mechanism, the object being to give pressure sufficient only to turn the
>pool through the medium of the drum in order to wind the slubbing thereupon or
to unwind it from the spool.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what
I claim is —
1. The combination of the drum, bearings therefor, a spool adapted to rest
against the drum and to be turned thereby, and an eccentrically curved bearing
surface for the spool, the incline of said bearing surface being greater as it nears
the drum, substantially as specified.
2. In a spool support, the frame having substantially horizontally extending
arms, a drum mounted in fixed bearings on said frame, with a spool having journals
by which it is suspended between the arms, whereby the arms take the major
portion of the weight of the spool, with means for pressing the spool against the
drum so that the pressure will be uniform, substantially as described.
3. The combination of the frame, the driving drum adapted to bearings thereon,
horizontal arms projecting from the side of said frame, a journalled spool supported
by said arms at the side of the drum, pivoted levers bearing against the journals of
the spool, and weights secured to the levers, substantially as described.
