Year: 1860

page_text: LETTERS PATENT to Leonard Kaberry, of Rochdale, in the County of
Lancaster, Manager, for the Invention of "IMPROVEMENTS IN MACHINERY
FOR APPARATUS FOR PREPARING, SPINNING, AND DOUBLING COTTON AND OTHER
FIBROUS MATERIALS,"
Sealed the 18th January 1861, and dated the 25th July 1860.
PROVISIONAL SPECIFICATION left by the said Leonard Kaberry at the
Office of the Commissioners of Patents, with his Petition, on the 25th
July 1860.
I, LEONARD KABERRY, of Rochdale, in the County of Lancaster, Manager,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR PREPARING, SPINNING, AND DOUBLING COTTON AND
OTHER FIBROUS MATERIALS," to be as follows:-
My Invention refers, firstly, to the carding engine, and consists in the
employment of a novel forin of guideor tightening pulley over which the chain
which drives the rollers passes. This pulley 1 form with indentations upon its
periphery corresponding to the shape of the links of which the said chain is
composed.
Secondly, my Invention relates to the throstie when two tin drums are
employed; these drums 1 cause to run in contact with each other, and for
this purpose I employ strips of leather or other such suitable material, and I
nount one or both in bearings capable of adjustment, so as to regulate the
friction of contact.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Leonard Kaberry in the Great Seal Patent Office on the
25th January 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LEONARD
KABERRY, of Rochdale, in the County of Lancaster, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of July, in the year ofour Lord One
thousand eight hundred and sixty, in the twenty-fourth year of Herreign, did,
for Herself, Her heirs and successors, give and grant unto me, the said
Leonard Kaberry, Her special license, that I, the said Leonard Kaberry, my
executors, administrators, and assigns, or such others as I, the said Leonard
Kaberry, 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
terin therein expressed, should and lawfully night make, usc., exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Chaunel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR PREPARING, SPINNING AND DOUBLING COTTON AND OTHER FIBROUS
MATERIALS," upon the condition, amongst others, that I, the said Leonard
Kaberry, by an instrument in writing under my hand and seal, should
ticularly 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.
par-
NOW KNOW YE, that I, the said Leonard Kaberry, do hereby declare the
nature of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
and accompanying Drawing (that is to say):-
My Invention refers, firstly, to the carding engine, and consists in the
employment of a novel form of guide or tightening pulley, over which the
chain which drives the rollers passes. This pulley I form with indentations
upon its periphery corresponding to the shape of the links of which the said
chain is composed.
Secondly, my Invention relates to the throatle, when two tin drums are
employed. These drums I cause to run in contact with each other, and for
this purpose I employ strips of leather or other such suitable material, and I
mount one or both in bearings capable of adjustment, so as to regulate the
friction of contact.
In the accompanying Drawing, the first part of my Invention is shewn at

page_text: Fig.1,which represents a guide or tightening pulley of a carding engine with
one flange removed. The chain which drives the rollers is at a, and the
guide or tightening pulley at b, formed with indentations c,into which the
links of the chain pass.
The second part of my Invention is shewn at Figs. 2 and 3, the former
being a representation of the end frame of a throstle with the two tin drums,
and the latter a cross section, shewing how one of these drums is mounted.
The description of throstle to which my Invention refers is well known, so
that the method by which one drum a is caused to drive a set of spindles, and
the other drumb another set will not now require explanation. The drum a is
driven byordinary means, and is furnished with a projecting rim c of leather
or other suitable material, which rim runs in contact with a similar rim d
attached to the drum b, and thus communicates rotatory motion thereto. In
order that there may be sufficient friction of contact for this purpose the
drun 6 is mounted in bearings, which are adjustable, and a method I adopt is
shewn at Fig. 3. One of the bearings is at e provided with a V-shaped part,
which is mounted in stationary guides f. Against this bearing is placed a
spring g, which has an abutment against a fixed part h, and thus the bearing
with the tin drum is forced forward so as to cause the rims c, d, to bear
against each other. Or in place of springs as shewn at g the required
contact may be obtained by sliding the bearing e, and then confining it by set
screws.
Having thus described and ascertained the nature of my said Invention,
and the manner in which the saine is to be performed, I desire it to be under-
stood that I claim as secured to me under the abovo in part recited Letters
Patent,
Firstly, forming the aforesaid pullies of carding engines with indentations
for the reception of the links of the chain.
Secondly, as applied to such throstles, as aforesaid, causing one tin drum to
drive another by contact therewith.
In witness whereof, I, the said Leonard Kaberry, have hereunto set my
hand and seal, this Twenty-fourth day of January, in the year of our
Lord One thousand eight hundred and sixty-one.
LEONARD KABERRY. (L.S.)
