I, WILLIAM HENCHMAN, of Leeds, in the County of York, Machine
Maker, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY OR APPARATUS USED IN THE PREPARATION OF FLAX, JUTE,
HEMP, TOW, AND OTHER FIBROUS MATERIALS FOR SPINNING," to be as follows:-
1
My Invention refers to improvements in machinery or apparatus for
preparing flax and other fibrous materials for spinning, and the In-
vention particularly refers to machines know as "spreaders," "drawing
frames," roving frames, "gill spinning frames," and other machines
of a like nature.
The first part of the Invention consists of improvements in the
bearings of the pressing rollers, as well as the means employed for
attaching the same to such machines, and the chief object of this part of
the Invention is to dispense with the side bearings now generally used
in machines of this description for supporting the pressing rollers.

page_text: To the bar known as the conductor bar I attach or cast thereon
stands, I extend the head of the bearing known as the "gib". or hook
bearing of each pair of pressing rollers, so that one end of such head
shall lie between and be interlinked with its respective afore-named
stand, and be therein capable of such vertical or lateral adjustment as
may be necessary. The head of such "gib" or hook bearing is then
carried over the top of the axle of its respective pair of pressing rollers,
and between them and to its other end I attach a lever by means of a
link, bolt, rod, hinge, or other suitable method of attachment, such lever
being connected with a weight, spring, or weighted lever, or other power
necessary to give the required pressure in the ordinary way. To the top
of the said bearing is or may be, as required, attached a fixed bar or
movable levers for carrying the cleaning rubbers. I prefer to arrange
the pressing rollers saddlewise, each pair of rollers being placed together
on one axle, and the bearing resting between them on such axle as
herein-before described, and in this manner I am able to entirely
dispense with the use of side bearings, as aforesaid.
The second part of my Invention has reference to the back conductors
used in the aforesaid machinery. Heretofore much difficulty has been
experienced in adjusting the position and distances of the conductors,
and the object of this part of my Invention is to obviate this incon-
venience. For this purpose I mount the back conductors on two rods or
bars, one side flange of each conductor being on one rod or bar, the
other side flange of each conductor being on the other rod or bar. At
one and the same end of each rod or bar, I form or cut a screw thread,
the thread on one rod or bar being right handed, while the thread on the
other is left handed; thus it will be understood that by communicating
motion to both rods or bars at one and the same time, and in the same
direction, that the side flanges of each conductor are brought nearer to
or extended farther from one another as required; and in this manner I
am able to regulate with the greatest nicety, and without trouble, the
' distance between the side flanges of the conductors.
