Machinist for an Invention of "IMPROVEMENTS IN MACHINERY FOR PREPARING
SPINNING AND DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES

PROVISIONAL SPECIFICATION left by the said James Macqueen at the
Office of the Commissioners of Patents on the 10th August 1883.
JAMES MACQUEEN of Bury in the County of Lancaster Machinist IMPROVEMENTS
IN MACHINERY FOR PREPARING SPINNING AND DOUBLING COTTON AND OTHER
FIBROUS SUBSTANCES
My first Improvement consists in drawing the lap as made by the Scutcher
before putting it up to the Card. I prefer to do this by applying a set of drawing
rollers betwixt the lap and the taker-in of the Carding Engine in lieu of the
ordinary feeder for the purpose of drawing straightening and opening the fibres of
the lap before it passes to the taker-in I do this either by a series of top
and bottom drawing rollers or by what is known as a dish feeder and series
of rollers combined
My second Improvement consists in an improved method of lubricating and
holding down the Spindles known as the Rabbeth or other Spindles where the
bolster and footstep are combined-But part of the Invention is also applicable to
other Spindles-Beneath the rail which carries the Spindles I carry a cup or trough
by any suitable means into it I insert the lower end of one or more of the pillars
which carries the spindles and form a communication betwixt the trough and the
spindle by drilling a hole through the pillar into the step-The Spindle is provided
with any of the ordinary means for lifting oil-Preferably I use a spiral groove
which lifts the oil up to the bolstor-the bolster is carried in the pillar in the
ordinary way-At the top of the bolster and under the top of the pillar I cut a
slot or slots in the pillar extending downwards beneath the bolster-Over the pillar
and covering the slot or slots I pass a thin ferrule oil tight at its lower end-The
lubrication takes place as follows into the cup or trough under the rail I put oil
which passes from the trough through to the spindle step and is lifted by the action

page_text: of the Spindle to the top of the bolster from which it passes down through the slot
or slots in the pillar and is returned to the Spindle at the bottom of the bolster-
When the Spindle is at rest all the oil returns to the cup or trough through the
step thus a perfect circulation of Oil is secured and all dirt is deposited in the
trough or cup and the necessity for washing pumping or removing the Spindle is 5
done away with.
My Improvement for holding down the Spindle is as follows-the upper part of
the hook which catches on the warve is formed in the usual manner-its lower
end is formed like a T headed bolt-A Slot is formed through the sole of the pillar
and a recess is made underneath the sole of the pillar the book passes through this 1
slot from beneath a tail piece is attached to the T head of the hook which passes
round the shank of the pillar and through a hole in the sole to the front-When
the Spindle is in position the hook is held forward by a small spring inside of the
recess and when-it is desired-to-take-the Spindle-out or put it in a slight pressure.
on the wire in front presses back the hook and spring and allows the warve of 1
the Spindle to pass.

MENTS IN MACHINERY FOR PREPARING SPINNING AND DOUBLING COTTON AND
OTHER FIBROUS SUBSTANCES.

My first improvement consists in drawing the lap as made by the Scutcher before
putting it up to the Card I prefer to do this by applying a set of drawing rollers
betwixt the lap and the taker-in of the Carding Engine in lieu of the ordinary
feeder, for the purpose of drawing straightening and opening the fibres of the lap
before it passes to the taker-in-I do this either by a series of top and bottom
rollers or by what is known as a dish feeder and series of rollers combined. My
second improvement consists in an improved method of lubricating and holding
down the Spindles known as the Rabbeth or other Spindles where the bolster and
footstep are combined but part of the invention is also applicable to other spindles.
And in order that my invention may be fully understood and readily carried into
operation I will proceed to describe the accompanying shoot of drawings referenco
being had to the figures and letters marked thereon. Figure 1 shows my first
improvement, a represents the Cylinder of a Carding Engine, 6 the taker-in, c the
lap, d tho set of drawing rollers for drawing the lap as it is fed forward to the
taker-in by the lap roller f. e is a set of drawing rollers combined with a dish
feeder. These rollers are weighted and geared up in the usual manner of such
drawing rollers. Figures 2 and 3 shew my second improvement and represent a
Rabbeth spindle with my improvements on the same. Beneath the rail which
carries the spindle a I carry a cup or trough 6 by any suitable means, into it I
insert the lower end of the pillar c which carries the spindle and I form a
communication betwixt the trough and the spindle by drilling a hole m through
the pillar into the step o The spindle is provided with any of the ordinary means
for lifting oil, preferably I use a spiral groove which lifts the oil up to the bolster d
from the step o, the bolster is carried in the pillar in the ordinary way. At the
top of the bolster and underneath the top of the pillar I cut a slot or slots e in the
pillar extending downwards beneath the bolster. Over the pillar and covering the
slot or slots I pass a thin ferrule foil tight at its lower end, or solder a piece of
tbin metal over the slot or slots. The lubrication takes place as follows. Into
the cup or trough under the rail I put oil which passes from the trough through
the spindle step and is lifted by the action of the spindle to the top of the bolster
from which it passes down through the slot or slots in the pillar and is returned to
the spindle at the bottom of the bolster. When the spindle is at rest all the oil
returns to the cup or trough through the step, thus a perfect circulation of oil is
secured and all dirt is deposited in the trough or cup and the necessity for washing,
pumping or removing the spindle is done away with. My improvement in holding
down the spindle is as follows:-The upper part of the hook g which catches on
the spindle warve is formed in the usual manner; its lower end is made like a
T headed bolt-a slot h is formed through the sole of the pillar and a recess i is
made underneath the solo of the pillar, the hook passes through this slot from
beneath. A tail piece is attached to the T head of the hook g and passes round
the shank of the pillar in the recess i and through a hole in the sole to the front,
or, hook and tail may be made in one piece.-When tho spindle is in position the
book is held forward by a small spring inside of the recess i and when it is
desired to take the spindle out or to put it in, a slight pressure on the wire
in front presses back the hook and spring and allows the warve of the spindle
to pass.

page_text: Having described the nature of my invention and the manner of performing
the same I claim First. The applying of a set of three or more pairs of drawing
rollers betwixt the lap and the taker-in of the carding engine (in lieu of the
ordinary feeder) for the purpose shewn and described. Second, The arrangement
for lubricating Spindles as described. Third, the arrangement and combination of
the hook g, tail pieco j and spring as described for holding down the spindle in
its.place
In witness whereof I the said James Macqueen have hereunto set my hand
and seal this sixth day of February in the year of Our Lord One thousand-
eight hundred and eighty four
