Year: 1866

page_text: LETTERS PATENT to David Cochrane, of Dunmurry, in the County of
Antrim, in Ireland, Spinning Master, for the Invention of "IMPROVE-
MENTS IN SPINNING FRAMES."
PROVISIONAL SPECIFICATION left by the said David Cochrane at the
Office of the Commissioners of Patents, with his Petition, on the 11th
June 1866.
I, DAVID COCHRANE, of Dunmurry, in the County of Antrim, in Ireland,
Spinning Master, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN SPINNING FRAMES," to be as follows:-
Instead of the ordinary spinning saddle having a transverse guide pin which
moves in slotted guides or grooves in stands placed at each side of the saddle,
I use a saddle having a longitudinal slot for the head of a single stand, and
having also an inclined transverse slot or groove for the guide pin which is
fixed in the single staud, so that the use of a second guide stand is dispensed
with.

and of an Order of the Lord Chancellor, by the said David Cochrane in
the Great Seal Patent Office on the 19th December 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
'COCHRANE, of Dunmurry, in the County of Antrim, in Ireland, Spinning
Master, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of Juue, in the year of our Lord One
thousand eight hundred and sixty-six, and in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said David Cochrane, Her special licence that I, the said David
Cochrane, my executors, administrators, and assigns, or such others as I,
the said David Cochrane, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN SPINNING FRAMES," upon the condition (amongst others)
that I, the said David Cochrane, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said David Cochrane, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying Drawings, and to the
letters and figures marked thereon (that is to say) :-
My Invention relates to a contrivance for supporting in a desired position
certain rollers used in frames for the spinuing of flax, hemp, jute, tow, and
similar substances.
A bracket or stand is attached to the bearer or part of a spinning frame at
the rear of the drawing and pressing rollers, and having a cross guide pin at
the outer end which supports a saddle; this saddle has a longitudinal slot to
admit the outer end of the bracket or stand, and a transverse inclined slot or
groove to admit the cross guide pin on which the saddle rests; the saddle is
furnished with pillow blocks or bearings, fitted and secured into or upon it, in

page_text: which the axles of the front rollers are supported. The lower pillow block
may be of the ordinary construction. The upper pillow block has a tongue,
which is passed through the longitudinal slot, and secured in any required
position in the saddle by a major screw or bolt working into a minor screw in
the end of the tongue. The axles of the front rollers may have collars turned
on them, between which the pillow blocks of the saddle bear (so that the
rollers cannot travel in an axial direction), and outside of which the front
rollers are placed, or they may be limited in borizantal motion by other
means. The spring, rod, or wire passes through the frame, and a hole in the
boss of the bracket or stand, and through the longitudinal slot in the saddle,
so that the front rollers may be kept at the necessary pressure against the
face of the respective back rollers.
In order that the said Invention may be more particularly described I shall
refer to the Drawings on the Sheet hereunto annexed, the same letters of refer-
ence indicating the same or corresponding parts throughout all the Figures.
Figure I. is a front view of the bracket saddle and supported rollers;
Figure II. is a section following the line X, Y, on Figure I; and Figure III..
is a section following the line, z, on Figure II.
A is the upper back roller; B, the lower back roller; C, the frame in the
rear of the back rollers; D, the spring rod or wire; E, E, the front rollers;
F, the lower pillow block.
a, the bracket or stand; b, the cross guide pin; c, the saddle; d, the
longitudinal slot; 6, the transverse inclined slot or groove; f, the upper pillow
block; 9, 9, the axles of the front roller; and h, h, are the collars turned on
the axles 9, 9.
Having now described the nature of the said Invention, and in what
manner the same is to be performed, I hereby declare that I do not claim
the collars on the axles nor the. rollers spring wire or rod separately, but
what I claim as my Invention is the saddle arranged with slots, and so as to
be supported in a desired position on a single bracket or stand for the
purposes above described.
In witness. whereof I, the said David Cochrane, have hereunto set my
hand and seal, this Eighth day of December One thousand eight hun-
dred and sixty-six.
DAVID COCHRANE. (L.B.)
