CENTAIN IM- PROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING, SLUBBING, AND ROVING COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1856

page_text: LETTERS PATENT to Joseph Lamb, of Manchester, in the County of
Lancaster, Spindle and Flyer Maker, for the Invention of "CENTAIN IM-
PROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING, SLUBBING, AND
ROVING COTTON AND OTHER FIBROUS SUBSTANCES."
Sealed the 24th February 1857, and dated the 3rd September 1856.
PROVISIONAL SPECIFICATION left by the said Joseph Lamb at the
Office of the Commissioners of Patents, with his Petition, on the
3rd September 1856.
I, JOSEPH LAMB, of Manchester, in the County of Lancaster, Spindle and
Flyer Maker, do hereby declare the nature of my said Invention for "CER-
TAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING, SLUBBING, AND
ROVING COTTON AND OTHER FIBROUS SUBSTANCES," to be as follows:-
My Invention relates to improvements upon the construction of the well-
known apparatus used in machines for preparing, slubbing, and roving, called
presser flyers," and particularly to that class or description of such flyers as
are called "centrifugal" presser flyers, (and whether such flyers have "single
pressers" or "double pressers,") whereby the required elastic pressure of the.
small spur or "presser" which conducts the sliver of cotton on to the bobbin
is obtained by the application of the principle of centrifugal force, instead of by
the use of springs, or other analogous mechanical pressure.

page_text: My improvement consists in suspending or mounting the presser with its
upright rod upon the hollow flyer leg in such a manner that the centre of
suspension or motion of the 'presser shall be concentric with the centre of the
flyer leg, which I accomplish by turning the upper extremity of the presser
rod into a hooked shape, and placing it in a small boss or cup at the top of the
flyer leg, in which it hangs by its hooked end, the point of which is immediately
concentric with the hollow flyer leg, or as nearly so as shall have the same
effect. This peculiar mode of hanging or mounting the presser will be
found still further to equalize or perfect its operation, as well as by dispensing
with the weight which has usually been applied, considerably to economize
the power required in working the machines.
A second improvement consists in placing a small pin or stud inside the
flyer leg in such a position that it shall prevent the "presser" rising up the
flyer leg, and also limit the extent of its horizontal action.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Lamb in the Great Seal Patent Office on the
3rd March 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
LAMB, of Manchester, in the County of Lancaster, Spindle and Flyer Maker,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of September, in the year of our Lord One
thousand eight hundred and fifty-six, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Joseph Lamb, Her especial license that I, the said Joseph Lamb,
my executors, administrators, and assigns, or such others as I, the said Joseph
Lamb, 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 "CERTAIN IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR PREPARING, SLUBBING, AND ROVING COTTON AND OTHER
FIBROUS SUBSTANCES," upon the condition, amongst others, that I, the said
Joseph Lamb, by an instrument in writing under my hand and seal, should
particularly describe and ascertain the nature of the said Invention, and in

page_text: 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Lamb, 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 improvements upon the construction of the well-
known apparatus used in machines for preparing, slubbing, and roving called
presser flyers, and particularly to that class or description of such flyers as are
called centrifugal pressers flyers, and whether such flyers have single pressers
or double pressers, whereby the required elastic pressure of the small spur or
presser which conducts the sliver of cotton on to the bobbin is obtained by the
application of the principle of centrifugal force, instead of by the use of springs,
or other analagous mechanical pressure.
My improvements consist in suspending or mounting the presser with its
upright rod upon the hollow flyer leg in such a manner that the centre of
suspension or motion of the presser shall be concentric with the centre of the
flyer leg, which I accomplish by turning the upper extremity of the presser
rod into a hooked shape, and placing it in a small boss or cup at the top of the
flyer leg, in which it hangs by its hooked end, the point of which is imme-
diately concentric with the hollow flyer leg, or as nearly so as shall have the
same effect. This peculiar mode of mounting or hanging the presser will be
found still further to equalize or perfect its operation, as well as by dispensing
with the weight which has usually been applied, considerably to economize
the
power required in working the machines.
A second improvement consists in placing a small pin or stud inside the
flyer leg, in such a position that it shall prevent the presser rising up the flyer
leg, and also limit the extent of its horizontal action.
In order that my Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawing, made about full size,
and having similar letters of reference marked upon corresponding parts of the
apparatus.
Fig. 1 is a front elevation of the flyer, shewing the cup or bearing above the
centre of the hollow leg, and the hooked end of the rod bearing therein, and
also the stop or pin at the lower extremity of such leg to prevent the "presser"
rising up the leg, and to limit the extent of its horizontal action; Fig. 2 is a
side view of the same, showing the bearing in section; and Fig. 3 is a plan
view of the presser and stop, taken through the line A, B. In Fig. 1 a, a, is

page_text: the flyer; and b, the hollow leg, immediately over the centre of which is placed
the cup or bearing c, in which the hooked end of the rod d bears. At the
lower termination of this rod is the presser e, which is prevented from rising
up the leg by the stud or projecting pin f, which also limits the horizontal
motion of the said presser. It will be evident that when a rotatory motion is
imparted to the flyer that an evenness or pressure will be exerted by the presser
upon the roving or slubbing, and a more balanced and steady motion will be
given to the flyer by reason of the centre of suspension of the presser being
immediately, or nearly so, above the centre of motion of the flyer leg, and
also that the action of the presser may be confined by the stop to any desired
size of bobbin.
Having now described the nature and object of my said Invention, together
with the method of performing the same, I would remark, in conclusion, that
I claim,―
First, placing the centre of suspension or motion of the presser concentric
with or immediately above the centre of the hollow flyer leg, and forming
thereupon a bearing or cup for the support of the hooked end of the presser
rod, or as nearly so as shall produce the same effect.
And, secondly, the application of the stud or pin to confine or limit the
action of the presser both in a vertical and horizontal direction.
In witness whereof, I, the said Joseph Lamb, have hereunto set my
hand and seal, this Second day of March, in the year of our Lord
One thousand eight hundred and fifty-seven.
JOSEPH LAMB. (L.S.)
