North Britain for an Invention of "IMPROVEMENTS IN SPINNING AND
TWISTING FRAMES FOR SPINNING OR TWISTING JUTE, FLAX, HEMP, Tow OR

PROVISIONAL SPECIFICATION left by the said Alexander Freir at the
Office of the Commissioners of Patents on the 30th December 1882.

ALEXANDER FREIR, of Dundee, in the County of Forfar, North Britain
'IMPROVEMENTS IN SPINNING AND TWISTING FRAMES FOR SPINNING OR TWISTING
JUTE, FLAX, HEMP, Tow OR OTHER FIBROUS SUBSTANCES,"
This Invention, which relates to improvements connected with frames for
spinning or twisting jute, flax, hemp tow or other fibrous substances, consists in
dispensing with what are commonly known in such spinning or twisting frames as
the neck or step rails for carrying the neck and step bearings and in substituting
therefor such rails, brackets, or pockets wherein the neck and step bearings are
inserted. The upper or neck bearing is carried in a gland piece attached to the
upper part of the bracket or pocket by screws and the bearing itself is made
conical with the largest part of the cone at the bottom of the bearing-The step
bearing is formed in the upper part of a screw plug fitting into the bottom of each
pocket. This plug is adjustable to any required degree of precision and is provided
with a check knot, or its equivalent for fixing it when adjusted. The pockets or
brackets wherein the step and neck bearing are inserted, are carried on a flat bar
extending across the length of the frame and each pocket or bracket constitutes a
cavity for containing oil or other lubricant which being charged therewith insures
perfect lubrication. The "wharve" or pulley for driving the spindle is attached
thereto as closely as it can be conveniently arranged above the neck bearing.

"IMPROVEMENTS IN SPINNING AND TWISTING FRAMES FOR SPINNING OR TWISTING
JUTE, FLAX, HEMP, Tow OR OTHER FIBROUS SUBSTANCES
"
My said Invention which relates to improvements connected with frames for
spinning or twisting jute, flax, hemp tow, or other fibrous substances, consists in
dispensing with what are commonly known in such spinning or twisting frames as
the neck or step rails for carrying the neck and step bearings and in substituting
for such rails, brackets or pockets wherein the neck and step bearings are inserted.-
The upper or neck bearing is carried in a gland piece attached to the upper part of
the bracket or pocket by screws and the bearing itself is made conical with the
largest part of the cone at the bottom of the bearing.-The step bearing is formed
in the upper part of a screw plug fitting into the bottom of each pocket. This plug
is adjustable to any required degree of precision and is provided with a check nut
or its equivalent for securely fixing it when adjusted. The pockets or brackets,
wherein the step and neck bearings are inserted, are carried on a flat bar extending
across the length of the frame and each pocket or bracket constitutes a cavity for
containing oil or other lubricant which being charged therewith insures perfect
lubrication. The "wharve" or pulley for driving the spindle is attached thereto
as closely as it can be conveniently arranged above the neck bearing.
And in order that my said Invention may be properly understood I now proceed
more particularly to set forth the systein, mode, or manner in or under which the
same is or may be used or practically carried into effect, reference, being had to the
accompanying Drawings and to the Letters and Figures marked thereon, that is
to say:
Figure 1, represents in front elevation the arrangement of mechanism constructed
according to and constituting my present invention.
Figures 2, and 3, represent the same respectively in vertical section and horizontal
section, the latter section of which is taken on the line A. B, Figure 1.
In carrying out my present Invention I dispense with what are commonly known
as the neck or step rails, which are ordinarily used in Spinning Frames for
carrying the neck and step bearings and I substitute for such rails, brackets or
pockets wherein the neck and step bearings are inserted.-The upper or neck
bearing a, of each spindle is carried in the gland piece b, attached by the screws c
or in any other suitable manner to the upper part of the bracket or pocket d, and
the bearing a, is made conical with the largest part of the cone at the bottom of
the bearing as shewn on the accompanying Drawings and it is secured in its
The step
required position within the gland b, by means of the set-screw e-
bearing f, is formed in the upper part of the screw-plug g, which is fitted into the
bottom of the pocket d, and is preferably made of gun metal or other analogous
metal. At the lower end of this screw-plug g, there is formed the squared portion h,
which admits of a "spanner" or key being placed thereon for the adjusting of the
said plug g, and the step bearing f-The check nut i, is provided upon the
screw g, for the purpose of securing the same by tightening it against the lower
end of the pocket d, in the position into which it has been brought on the turning
of the said plug g.-The brackets or pockets d, wherein the steps f, and neck
bearing a, are inserted, are carried on the flat bar j, extending across the length of
the spinning frame, being attached thereto by the screws k, or by any other
suitable means and each bracket or pocket d, constitutes a cavity for containing

page_text: the oil, or other lubricant which, being charged therewith insures perfect
lubrication. The "wharve" or pulley m, for driving each spindle n, is attached
thereto as closely as it can be conveniently arranged above the neck bearing a.
By means of the arrangement of spindles and their attachments to spinning and
twisting frames as herein before described, the bearings a, and f, always being
properly lubricated, a great saving of wear is effected and they can be kept cool in
mineral lubricating oil; by reason of the pocket d, being of sufficient size to
contain a considerable quantity of oil, the spin lle n, is enabled to run for a
lengthened period, without the necessity of further oil being added.-A further
advantage is, that there is less liability for the spindles to get out of line as they,
being always in oil, the step bearings f, do not wear as hitherto when fitted up in
the ordinary way.
Having now described and particularly ascertained the nature of my said
Invention and the system, mode or manner in or under which the same is or may
be used or practically carried into effect, I would observe in conclusion that what
I consider to be novel and original and therefore claim as the Invention secured to
me by the herein before in part recited Letters Patent is :-
In Frames for spinning or twisting Jute, flax, hemp, tow or other fibrous
substances the mechanism represented on the accompanying Sheet of Drawings
and operating substantially as and for the purposes herein before described, con-
sisting of the parts referred to by the Letters a, to n, both inclusive, or the
mechanical equivalents of all or any of the said parts.
In Witness Whereof I, the said Alexander Freir have hereunto set my hand
and seal this Twenty-seventh day of June in the year of our Lord One
thousand eight hundred and eighty-three.
ALEXANDER FREIR (L.S.)
