GEORGE MARCH, of Leeds, in the County of York, Engineer. "IMPROVEMENTS
IN MACHINERY FOR SPINNING FLAX, Tow, HEMP, AND OTHER FIBROUS SUB-
STANCES."
This Invention has for its object improvements in machinery for spinning flax,
tow, hemp, and other fibrous substances.
Heretofore in the drawing apparatus of hot water spinning frames the "saddle"
is made with arms projecting at each side, by which it rests on its stand or support,
and these arms partially extend over or in front of the bottom pressing rollers, the
diameter of which is thus limited. Now according to my Invention these arms
are dispensed with by the substitution therefor of guides or grooves on the external
sides of the "saddle." The stand or support which carries the "saddle" and spans.
it, thereby steadying it, has two pins facing inwards, which pins fit into the external
guides or grooves on the said "saddle;" thus the "saddle" and stand are inade
sufficiently narrow to be received into the space between the lower pressing rollers.
I arrange the parts in the following manner:-On a beam running horizontally
from end to end of the frame are mounted at intervals brackets which carry the
bearings of the retaining and drawing rollers, and the bearings of the retaining
rollers are capable of adjustinent up or down by slides on the brackets, so that the.
distance between the retaining and drawing rollers may be varied as required.
The bearings of the top pressing rollers and of the bottoin pressing rollers are
carried in "saddle" pieces. The pressing rollers are made in pairs and the "saddle"
bears on the axle or spindle between the two rollers of the pair, one end of cach
"saddle" bears on the axle or spindle of a pair of top pressing rollers, and the.
other end on the axle or spindle of a pair of bottom pressing rollers. There is a
slide on the "saddle," so that the distance between the bearings of the top and
bottom rollers may be adjusted to correspond to the distance at which the retaining
and drawing rollers are set. The saddle" has on each of its external sides a guide
or groove, into which the pins of the stand fit, thereby supporting the said "saddle."

page_text: The weight or pressure is applied to the "saddle" and to the pressing rollers by a
rod connected with a weighted lever; this rod passes through the support or stand
centrally, and also through the "saddle," receiving beyond a ring and nut; the ring
has knife edges upon it which bear upon the "saddle." By this arrangement the
"saddle" is made narrower than the space between the pressing rollers, con-
sequently the size of these rollers are not limited by them as they are in the
ordinary arrangement.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said George March in the Great Seal Patent Office on the 1st August 1876.
GEORGE MARCH, of Leeds, in the County of York, Engineer. "IMPROVEMENTS
IN MACHINERY FOR SPINNING FLAX, Tow, HEMP, AND OTHER FIBROUS SUB-
STANCES."
This Invention has for its object improvements in machinery for spinning flax,
tow, hemp, and other fibrous substances.
Heretofore in the drawing apparatus of hot water spinning frames the "saddle"
is made with arms projecting at each side, by which it rests on its stand or support,
and these arms partially extend over or in front of the bottom pressing rollers, the
diameter of which is thus limited. Now according to my Invention these arms
are dispensed with by the substitution therefor of guides or grooves on the external
sides of the "saddle." The stand or support which carries the "saddle" and spans
it, thereby steadying it, has two pins facing inwards, which pins fit into the
external guides or grooves on the said "saddle," thus the "saddle" and stand are
made sufficiently narrow to be received into the space between the lower pressing
rollers.
I arrange the parts in the following manner-On a beam running horizontally
froin end to end of the frame are mounted at intervals brackets which carry the
bearings of the retaining and drawing rollers, and the bearings of the retaining
rollers are capable of adjustment up or down by slides on the brackets, so that the
distance between the retaining and drawling rollers may be varied as required.
The bearings of the top pressing rollers and of the bottom pressing rollers are
carried in saddle" pieces. The pressing rollers are made in pairs and the "saddle
bears" on the axle or spindle between the two rollers of the pair, one end of each
"saddle" bears on the axle or spindle of a pair of top pressing rollers and the other
end on the axle or "spindle" of a pair of bottom pressing rollers. There is a slide on
the "saddle" so that the distance between the bearings of the top and bottoni
rollers may be adjusted to correspond to the distance at which the retaining and
drawing rollers are set. The "saddle" has on each of its external sides a guide
or groove into which the pins of the stand fit, thereby supporting the said "saddle."
The weight or pressure is applied to the "saddle" and to the pressing rollers by
a rod connected with a weighted lever, this rod passes through the support or stand
centrally, and also through the "saddle," receiving beyond a ring and nut, the ring
lias knife edges upon it which bear upon the "saddle." By this arrangement the
"saddle is made narrower than the space between the pressing rollers, con-
sequently the size of these rollers are not limited by them as they are in ordinary
arrangement.
"
And in order that my Invention may be more completely understood, reference
is given to the accompanying Sheet of Drawings and to the letters and marks
thereon.

page_text: a is the beam; it is part of the main frame and runs horizontally from end to end
of the machine; bare brackets bolted to the beain a, they support the slides c;
these slides are capable of adjustment by turning the screws c₁; dare stands or
supports for the saddles, they are also bolted to the beam a, one of them is shewn
separately in plan at Figure 3, and in front elevation Figure 4; e are the saddles, onc
of them is shewn separately in plan at Figure 5; fare the slides on the saddles for
carrying the top pressing rollers. The slide is capable of being clamped on the
saddle nearer to or further from the guides or grooves on the external sides of the
saddle, so that the top pressing roller may be adjusted in position to correspond
with that of the retaining roller; are rods passing through the centre of the
Each rod at one end is hooked
stands or supports d and through the saddles e.
to a lever , carrying a weight upon it, or a spring may be substituted for this
weight, and at the other end each rod receives a ring g', having knife edges
bearing upon the saddle and a nut gto keep the ring in its place; i are brackets,
carrying the centres of the levers h; J are the retaining rollers, the axes of which
are carried in bearings on the slides c; are the drawing rollers, the axes of which
are carried in bearings fixed upon the brackets b; 1 are the top pressing bosses or
rollers, their axes are supported in bearings on the slides on the saddle; m are
the bottom pressing bosses or rollers, their axes are supported directly by the fixed
bearings of the saddle, which are prolonged to assist in lubricating by conveying
the oil to the axes.
Having now described the nature of my said Invention, and shewn by Drawings
how the same may be carried into practice, I would have it understood that I do
not limit myself to the exact limits, details, or configuration of the various parts I
have expressed and shewn, as the same may be varied or modified without in any
way departing from the nature or principle of my Invention; but what I do claim
and desire to be secured to me by Letters Patent is, the arrangement, construction,
and application of the saddles of spinning frames, and the supports or stands which
carry them, substantially as and for purposes herein set forth.
In witness whereof, I, the said George March, have hereunto set my hand
and seal, this Thirty-first day of July, in the year of our Lord One thousand
eight hundred and seventy-six.
