BENJAMIN BROWN, of Bury, in the County of Lancaster. IMPROVEMENTS IN
THE CONSTRUCTION OF MACHINERY OR APPARATUS FOR SPINNING AND DOUBLING
COTTON AND OTHER FIBROUS SUBSTANCES."
This Invention relates chiefly to improvements in the construction of various
parts of the machines known as the "ring throstle" and the "ring doubler,"
but portions thereof are also applicable to other kinds of spinning and doubling
frames.
The first part of my Invention relates to the "wire boards," to which are fixed
the wire guides through which the threads pass. It is necessary that each separate
wire board should be capable of being raised up independently when required for
piecing or other purposes, and that the whole series should be capable of being
raised or otherwise moved out of the way for doffing the bobbins.
Instead of hingeing the "wire boards" to the front of the roller beam, or to a
fixed rail as usual, I hinge them onto a rail which is movable and is capable, by.
means of a rack and pinion or other suitable device, to be drawn inwards under the
roller beam so as to move all the wire guides simultaneously out of the way for
doffing; each "flap" is made with a cast iron casing enclosing a piece of wood into
which the thread wire is screwed.
The second part of my Invention relates principally to what is known as the
"rabbeth spindle," and especially to the method of fixing into the spindle rail
the long sleeve or collar in which the spindle revolves, and consists in the use below
the spindle rail of a loose ring or loop fitting round the lower portion of the collar,
and provided with chisel-edged teeth or projections on its upper side. The hole in
the spindle rail is bored out rather larger than the diameter of the lower part of
the collar, so that the latter can be adjusted in any direction till the spindle is
absolutely perpendicular and in the centre of the ring. The loose ring or loop is
Drina arr

page_text: then placed on the lower part of the collar and screwed up by means of one or two
nuts (one being a nut lock), which will force the teeth or projections to take
firm hold of the lower side of the spindle rail, and thus hold the collar firmly in
position.
This part of my Invention is applicable for fixing any other kind of bolsters or
footsteps for spindles.
A third part of the Invention relates to an apparatus for retaining the outer
tube and wharve in position, and preventing them from being withdrawn when the
bobbins are doffed. This part of the Invention consists in mounting a shaft along
one edge of the spindle rail, such shaft being carried in bearings and capable of
being turned a portion of a revolution.
On this shaft are fixed a series of catches (one for each spindle), which, when in
working position, project above the upper edge of the wharves and prevent their
rising, but can all be instantly and simultaneously withdrawn by turning the shaft
partly round, and restored to their original position by the reverse movement.
A fourth part of the Invention relates to an apparatus for lowering the "ring
plate" to the level of the bottom of the bobbins when required for doffing.
The "ring-plate" is traversed up and down so as to wind on the yarn in the form
of a cop by means of a chain actuated by a heart wheel and lever in the usual
manner, one end of the chain being fastened to a roller or block on the lever
provided with a ratchet wheel and worm gear by means of which the chain can
be unwound, and the ring plate lowered in whatever position the heart wheel
may be.
To adjust this movement with greater accuracy the carrier rollers over which
the chains pass, instead of being supported in fixed bearings, are carried at the
lower end of a suspended lever or arın, the exact position of which can be adjusted
by means of a screw or otherwise.

"IMPROVEMENTS IN
THE CONSTRUCTION OF MACHINERY OR APPARATUS FOR SPINNING AND DOUBLING
COTTON AND OTHER FIBROUS SUBSTANCES."
This Invention relates chiefly to improvements in the construction of various
parts of the machines known as the "ring throstle" and the "ring doubler," but
portions thereof are also applicable to other kinds of spinning and doubling frames.
Such being the nature and object of my said Invention I will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect; and in order that the same may be clearly understood
I have annexed hereunto a Sheet of Drawings illustrative thereof, and have marked
the same with figures and letters of reference corresponding with those in the
following explanation thereof.
The first part of my Invention relates to the "wire boards," to which are fixed
the wire guides through which the threads pass, and is illustrated by Fig. 1 in the
annexed Drawing, which represents a vertical section through the roller beam and
wire board.
It is also illustrated on a smaller scale on Fig. 3, which is a partial front view of
the machine, a, a, being the roller beam, and b, b, the wire boards. It is necessary
that each separate wire board b, b, should be capable of being raised up inde-
pendently when required for piecing or other purposes, and that the whole series
should be capable of being raised or otherwise moved out of the way for doffing
the bobbins.
Instead therefore of hinging the wire boards b, b, to the roller beam a, a, or to a
fixed rail as usual, each flap is made with a cast iron casing b, b, enclosing a piece
of wood b¹, into which the wire c, c, is screwed (see Fig. 3), and I hinge the pieces
b, b, onto a rail d, (see Figs. 1 and 3,) which is movable, and is capable by means
of a rack and pinion e, e, or by an excentric, incline, lever, or other suitable device,
to be drawn inwards under the roller beam a, a, as seen at Fig. 1, so as to move all
the wire guards simultaneously out of the way for doffing.
The second part of my Invention is illustrated by Fig. 4, which is an elevation
of a rabbeth spindle, showing the spindle rail in action.
This part of my Invention relates principally to what is known as the rabbeth
spindle, and more especially to the method of fixing into the spindle rail f, f, the
long sleeve or collar g, g, in which the spindle h, h, revolves, and consists in the use
below the spindle rail f, f, of a loose ring or hoop i, i, (see also plan view detached,
Fig. 5) fitting round the lower part of the collar, and provided with chisel shaped
teeth or projections k, k, on its upper side. The hole in the spindle rail f, f, is
bored out rather larger than the diameter of the lower part of the collar g, g, so
that the latter can be adjusted in any direction till the spindle h, h, is absolutely
perpendicular and in the centre of the ring. The loose ring or hoop i, i, is then
placed on the lower part of the collar g, g, and screwed up by means of one or two
nuts 1, 1, (one being a lock nut) which will force the teeth or projections k, k, to
take a firm hold of the lower side of the spindle rail f, f, and thus hold the collar
g, g, firmly in position. This part of my Invention is applicable for fixing any
other kinds of bolsters or footsteps for spindles.
The third part of my Invention is also illustrated by Fig. 4, and relates to the
apparatus for retaining the outer tube and wharve m, m, in position, and preventing
them from being withdrawn when the bobbins are doffed. This part of the

page_text: Invention consists in mounting a shaft n, n, in a planed groove formed along the
edge of the spindle rail f, f, such shaft being carried in bearings and being capable
of being turned a portion of a revolution. On this shaft n, n, are fixed a series of
catches o, o, (one for each spindle, which, when in working position, as drawn,
project above the upper edge of the wharves m, m, and prevent their rising, but
can all be instantly and simultaneously withdrawn (as shown in dotted lines) by
turning the shaft n, n, partly round, and restored to their original position by the
reverse movement.
I may here remark that I make no claim to the catches o, o, but only to the
method of mounting and fixing the shaft n, n,' as described.
The fourth part of my Invention is illustrated by transverse section, Fig. 2, and
partial front elevation, Fig. 3, and relates to an apparatus for lowering the "ring
plate" p, p, to the level of the bottom of the bobbins when required for doffing.
The ring plate p, p, is traversed up and down so as to wind on the yarn in the
form of a cop by means of a chain q, q, actuated by a heart wheel r, r, and lever s8, 8,
in the usual manner, one end of the chain q, q, being fastened to a roller or block t, t,
on the levers provided with a ratchet wheel u, u, and worm gear v, v, by means of
which the chain q, q, can be unwound, and the ring plate p, p, lowered in whatever
position the heart wheel may be. To adjust this movement with greater
accuracy the carrier rollers tv, w, over which the chains q, q, pass, instead of being
supported on fixed bearings are carried at the lower end of a suspended lever or
arm x, x, the exact position of which can be adjusted by means of a screw y, y,
or otherwise.
Having now described the nature and object of my said Invention, together
with the manner in which the same is to be or may be performed or carried into
practical effect, I wish it to be understood that I claim as my Invention the several
improvements in the construction of spinning and doubling frames, as herein before
described and illustrated by the Drawings annexed, or any mere modification or
imitation thereof, constructed and operating in substantially the same or a similar
manner.
In witness whereof, I, the said Benjamin Brown, have hereunto set my hand
and seal, this Twenty seventh day of May, in the year of our Lord One
