page_text: LETTERS PATENT to Leonard Kaberry, of Rochester, in the County of
Lancaster, Mechanical Engineer, for the Invention of "IMPROVEMENTS.
IN MACHINERY FOR. PREPARING. FIBROUS MATERIALS, COMMONLY CALLED..
SLUBBING INTERMEDIATE. AND. ROVING FRAMES."
PROVISIONAL. SPECIFICATION left by the said Leonard Kaberry at the
Office of the Commissioners, of Patents, with his Petition, on the 18th
March 1866.
I, LEONARD KABERRY,. of Rochdale,. in the County of Lancaster, Mechanical
Eugineer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY FOR PREPARING FIBROUS MATERIALS, COMMONLY CALLED
SLUBBING, INTERMEDIATE, AND ROVING FRAMES," to be as follows:-
My Invention relates to a method of communicating motion from the
"differential" arrangement to the shaft which drives the bobbins. For this
purpose I employ a toothed pinion equal in length to the lift of. the copping
rail; this pinion is driven by the above-mentioned differential motion, and in
its turn imparts motion to a pinion connected with the bobbin shaft. As
therefore this shaft moves in the ordinary manner upward and downward its
pinion is always in gear with the aforesaid long pinion and the driving power
is maintained.

by the said Leonard Kaberry in the Great Seal Patent Office on the
18th September 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LEONARD
KABERRY, of Rochdale, in the County of Lancaster, Mechanical Engineer,
send greeting
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of March, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Leonard Kabberry, 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 there-
after 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 "IMPROVE-
MENTS IN MACHINERY FOR PREPARING FIBROUS MATERIALS, COMMONLY CALLED
SLUBBING, INTERMEDIATE, AND-ROVING FRAMES," upon the condition, amongst
others, that I, the said Leonard Kaberry, by an instrument in writing under
my hand and seal, 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 Leonard Kaberry, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings, that is to say :—
.
My Invention relates to a method of communicating motion from the
"differential" arrangement to the shaft which drives the bobbins. For this
purpose I employ a toothed pinion equal in length to the lift of the copping
rail. This pinion is driven by the above-mentioned differential motion, and
in its turn imparts motion to a à pinion connected with the bobbin shaft. As
therefore this shaft moves upward and downward in the ordinary manner its
pinion is always in gear with the aforesaid long pinion and the driving power
is maintained.
In the accompanying Drawing Fig. 1 represents a portion of a roving

page_text: frame constructed according to my Invention in elevation, and Fig. 2 is a
plan view thereof. The shaft of the usual "differential " motion is at a, upon
which is a bevil pinion 6 taking into another c fixed to a shaft d. At the
lower part of the shaft d is a spur pinion e in gear with a pinion f, which
is equal in length to provide for the lift of the copping rail. On the other
side of this long pinion, and in gear therewith, is a pinion 9 fixed upon a
shaft h, which is carried by the copping frame o, and this shaft by means of
a bevil i drives another bevil k so as to give motion to the back bobbin shaft l.
The front bobbin shaft m is driven by pinions n, p, as usual. It will now
be seen that as the copping frame o which carries the pinion g moves upward
and downward the said pinion g, will always receive rotatory motion from
the long pinion f, and the bobbin shafts l, m, will therefore continue to be
driven at a speed regulated by the differential motion. The pinion ƒ has
been stated to be as long as the lift of the copping rail, but it must of course
be also provided with an extra length for the pinion g to keep in gear. .
Having thus described and ascertained the nature of my said Invention,
and the manner in which the same is to be performed, I desire it to be
understood that I claim, as secured to me under the above in part recited
Letters Patent, the use of the long pinion f for the purpose above set
forth.
In witness whereof, I, the said Leonard Kaberry, have hereunto set my
hand and seal, this Twelfth day of September, in the year of our Lord
LEONARD KABERRY. (L.S.)
