IMPROVEMENTS RELATING TO SPINDLES AND BOBBINS FOR SPINNING OR TWISTING MACHINES
Year: 1884

page_text: I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my Invention for "IMPROVEMENTS RELATING TO SPINDLES AND BOBBINS FOR
SPINNING OR TWISTING MACHINES" 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 the present Invention is to provide a device for the spindles of
spinning and twisting frames, which will cusure the continuous turning of the
bobbin or spool, whether it rises up on the spindle upon which it is set or rests
upon its bearing below.
And the said Invention will be fully understood from the following description,
reference being had to the accompanying Drawing, in which
Figure 1, is a side elevation of a spindle, showing the loose enveloping sleeve
and its base, with two feathers upon the said sleeve.
Figure 2 is a horizontal transverse section, on the line V, W, Figure 3, of the
spool in place upon the sleeve, and of the spindle, the top of the enveloping sleeve,
and the lower flange of the spool being shewn in plan.
Figure 3 is an elevation of the spindle and a vertical section of the spool, the
loose sleeve, and its base upon which the spool rests.
Figure 4 is a section on the line X, Y, Figure 3, shewing parts of the spindle,
the spool and the sleeve, to show that the bore of the spool is larger in that part
which surrounds the sleeve, than in its continuation above the sleeve, where it
surrounds and comes in contact with the spindle A.
Figure 5, is a vertical sectional view of an ordinary bobbin with a tube inserted
through the bore thereof to receive the spindle.
A is the spindle, the base of which rests below in the spindle-rail of the spinning
or twisting frame, when in use. C is a loose sleeve surrounding the spindle; C' is
the base or "wall" of the sleeve C; E, E¹ are two "feathers " or "splines" upon
opposite sides of the sleeve C. D¹, D" are the upper and lower flanges of the

page_text: spool D. F. F are two longitudinal grooves in the opposite sides of the bore or
interior of the spool D, which terminate above, before reaching the upper extremity
of the bore, thus leaving the bore of the spool intact for a short distance above the
upper end of the sleeve, (see G G) and permitting that portion of the bore to fit
the spindle snugly. These grooves, without detriment to the operation of the said
device, may be continued up throughout the whole length of the bore of the spool,
as they necessitate the removal of only a comparatively small portion of the
interior of the bore, as will be seen in Figure 2 in horizontal transverse section.
The bore of the tube at its upper flange I make so much smaller than that portion
of it surrounding the sleeve C as to enable it to fit the spindle A, about as closely
as the larger part of the bore fits the sleeve C; whereby, when the spool, in
operation, creeps or rises up, it will be guided in its vertical movement by the
upright spindle. When the old device of two short pins projecting up from the
upper surface of the base or "wall" C¹ was used, the least upward movement of
the spool upon the spindle or sleeve C freed the bobbin from the pins and it ceased
to revolve, but by the use of the feathers E, E' in the long grooves F, F¹, the spool
or bobbin may be permitted to rise nearly or quite to the upper end of the spindle
before it will be freed from the necessity of turning with the sleeve and its
feathers.
In the Drawing, I have represented the feathers E, E as being very short; they
may be elongated down towards the base of the sleeve C, as far as may be desired.
I have shown two feathers or splines, though one may be dispensed with, and only
one groove used if desired; but by the use of two feathers in two grooves, I find
that a more even revolution of the spools is obtained, than by the use of one.
The sleeve C may be made in one piece with the base or "wall" C¹, or it may
be secured thereto by shrinkage or otherwise. .
In transverse section in Figure 2, I have shown the grooves very wide and the
feathers very narrow, this is simply for the sake of clearness; in practice the
grooves are narrower than thus shown, and the feathers fit more snugly therein,
but the spool is capable of moving freely up and down upon the spindle A and
sleeve C. The sleeve C, when in place, is revolved by a band or cord upon the
spinning frame, which cord passes around the neck of the base or "wall" Ĉ¹ of the
sleeve, at the point where the said letter C' is placed in the Drawing; the sleeve C
turns freely upon the spindle A. H is a long rail or lifter plate through which the
spindles and the aleeves or tube C project, see Figure 3, and I is a similar rail
upon which the bases or "walls" C of all the sleeves C rest. The spindle rests
below in the ordinary rail well known to those skilled in the art to which the
said Invention appertains.
Instead of grooving the interior of the bobbin as at F, the bore of the bobbin
may be increased in diameter, and a tube inserted therein which may be grooved
internally and longitudinally so as to correspond with the grooving of the actual
bore of the bobbin. In other words the interior of this tube represents, when it is
inserted, the grooved interior of the bobbin shown in the Drawing. This tube
may be secured in the interior of the bobbin in any desired manner, for example,
by means of an outer feather or projection upon the tube, see Figure 5 fitting into
a groove in the interior of the bobbin, so that the bobbin and its tube can be
readily separated.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:-
First. The combination of a spindle A, provided with a loose sleeve C which is
provided with a feather E, and a spool or bobbin D having a groove F adapted to
engage with the said feather E, the bore of the said bobbin being a lapted to fit
snugly around the said sleeve, substantially as described.
Secoud. The combination of a spindle A, provided with a loose sleeve C which
is provided with a feather E, and a spool or bobbin D having a groove F adapted
to engage with the said feather E, the lower part of the bore of the said bobbin

page_text: fitting snugly around the said sleeve, and the upper part of the bore being smaller
as at G G and fitting snugly around the spindle A, above the upper end of the
sleeve C, when in place, substantially as described.
Third. The combination of a spindle A, provided with a loose sleeve C which
is provided with a feather E, and a spool or bobbin D having a groove F adapted
to engage with the said feather E, the bore of the said bobbin being adapted to fit
snugly around the said sleeve, the lower part of the sleeve C terminating in a base
or "wall" C which is provided with a neck or groove to receive the actuating
band or cord from the spinning frame, substantially as described.
Fourth. In a bobbin or spool D, the internal groove F, the latter being adapted
to receive a feather fixed on an internal spindle upon which the said spool or
bobbin may be set, substantially as described.
Fifth. A spindle for spinning frames provided with a sleeve C, having upon its
outer convex surface a feather or projection E, substantially as, and for the
purposes, described.
Sixth. In a bobbin or spool D, the internal groove F, adapted to receive a
feather as described, the bore of the said bobbin being of varying diameter, the
lower part of the said bore being of a size adapted to fit over a sleeve C, and the
upper part G G being contracted to clasp a spindle A at a point above the sleeve,
substantially as described.
