page_text: LETTERS PATENT to Edward Scott, of the City of Manchester, in
the County of Lancaster, for the Invention of "IMPROVEMENTS IN
WEIGHTING MOTIONS USED IN MACHINERY FOB PREPARING, SPINNING,
TWISTING, AND DOUBLING FIBROUS MATERIALS, AND FOR OTHER SIMILAR
PURPOSES." A communication from abroad by Windsor Brothers,
of Lille in the Empire of France.
COMPLETE SPECIFICATION filed by the said Edward Scott at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 2nd July 1869, pursuant to the 9th Section of
the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
SCOTT, of the City of Manchester, in the County of Lancaster, send
greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS
IN WEIGHTING MOTIONS USED IN MACHINERY FOR PREPARING, SPINNING, TWISTING,
AND DOUBLING FIBROUS MATERIALS, AND FOR OTHER SIMILAR PURPOSES," and have
petitioned Her Majesty to grant unto me, my executors, administrators,

page_text: and assigns, Her Royal Letters Patent for the same, and have made
solemn Declaration that the same has been communicated to me from
abroad by Windsor Brothers, of Lille, in the Empire of France.
NOW KNOW YE, that I, the said Edward Scott, do hereby declare
that the following Complete Specification, under my hand and seal,
fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement and accompanying Sheet of Drawings (that is to say) :-
This Invention consists in an improved combination of levers actuated
by a single weight working in connection with an improved saddle for
enabling the power produced by the weight and leverage to be distributed
equally or unequally on the top or feeding rollers, and on the bottom or
drawing rollers of the machine. For example, suppose there is a
pressing power of 100lbs. and it is required to apply 30lbs. on the top
rollers, and the remaining 70lbs. on the bottom rollers, these improve-
ments enable the power to be applied in this or any other proportion with
great facility.
The manner in which this Invention is to be performed will be clearly
understood by the following description thereof, reference being had to
the Figure on the accompanying Sheet of Drawings, and to the letters
of reference marked thereon, the Figure being an end view of one
arrangement of our improved weigh'ting motions adapted to a wet flax
spinning frame.
a represents one of the feeding roller ; 6, one of the pressing rollers
of the feeding rollers; c, one of the drawing rollers; and d, one of the
pressing rollers of the drawing rollers. The saddle marked e hangs or
swivels from a longitudinal bar or rod ffixed at any convenient distance
before, above, or behind the feeding rollers, and the lower end of the
saddle carries the step or brass which presses on the central shaft or
spindle g of the pressing rollers d. The great length of this saddle
admits of placing and using a very small as well as a very large pressing
roller d, and the large arc it describes admits of so doing without 'the
centre of the said pressing roller deviating to any injurious 'extent from a
right line with the centre of the drawing roller c by the saddle e;
between the bar f and the bottom rollers c, d, there is a block / with a
groove at each side, and the block can be placed at any required position
on the shank of the saddle and held fast by the set screw i. This block
carries a movable slide piece formed at one end as a brass or step fitted

page_text: to the central shaft or spindle k of each pair of pressing rollers 6, and
this slide has through it a pin to which one end of a top pressing
link m is hooked and therefore receives the pressure intended to be con-.
veyed to the top feeding rollers, and the other end of the link is hooked
to a pin in the top end of a double lever n, o, working on a fulcrum p
in a bracket q fixed to the stationary cross frame or rail ».
For giving
pressure to the bottom driving rollers I employ a second or bottom
pressure link & having a screwed end passed through the saddle and
provided with a nutt for regulating its length according to the diameters
of the pressing rollers d, and the other end of this second link 8 is
hooked to the pin " in the weight lever working on a fulcrum w in the
lower end of the double lever n, o, and carries the weight x. Thus the
lever v with its weight at one end has its fulcrum in the double
lever n, o, not absolutely stationary but capable of motion in itself and
causing proportionate motion to the other end of the double lever. The
power of the weight x and lever o is exerted on the pin u and the bottom
pressing link 8, and presses the pressing rollers d against the drawing
rollers c, and the top pressing rollers are pressed against the feeding
rollers a by the movement of the top of the double lever n, o, and the
pressing link m, the pressure upon the top rollers being in proportion to
the lengths of the arms n, o, and by varying the centre or fulcrum of
this double lever, it is obvious that the proportions of the weights to be
applied to the top and bottom rollers are also varied. The brackets for
carrying the double levers n, o, are placed behind the rollers, or in any
other convenient positions, and the various parts are modified to suit the
various sizes and requirements of the several machines, and the centres
or bearings of the double levers may either be variable in slots in the
said levers or have stationary bearings placed as required.
It will be seen that the main features of this Invention consist,-
First. In connecting a weighting link for the bottom rollers to a pin
in a weighted lever working on a fulcrum in the other arm of the double
lever, it being understood that the centre or bearing of the double lever
is to be placed according to the equal or unequal pressures required for
the top and bottom rollers.
And, secondly. In an improved form of saddle for enabling pressing
rollers of large and small diameters to be used in connection with
the drawing rollers.
Having now described the nature and particulars of the said Invention

page_text: as communicated to me, I desire it to be understood that I claim, the
improvements in weighting motions used in machinery for preparing,
spinning, twisting, and doubling fibrous materials, and for other similar
purposes, as herein desoribed and illustrated in the accompanying Sheet
of Drawings.
In witness whereof, I, the said Edward Scott, have hereunto set
my hand and seal, this Twenty-ninth day of June, in the
year of our Lord 1869.
