Year: 1866

page_text: LETTERS PATENT to Charles Hastings and James Briggs, of the Firm
of Messrs. Charles Hastings and Company, of Bradford, in the County
of York, Manufacturers, and James Law and Hiram Mitchell, of the
same Place, Managers, for the Invention of "IMPROVEMENTS IN MACHINERY
FOR SPINNING AND DOUBLING."
Sealed the 19th October 1866, and dated the 20th April 1866.
PROVISIONAL SPECIFICATION left by the said Charles Hastings, James
Briggs, James Law, and Hiram Mitchell at the Office of the Commis-
sioners of Patents, with their Petition, on the 20th April 1866.
We, CHARLES HASTINGS and JAMES BRIGGS, of the Firm of Messieurs
Charles Hastings and Company, of Bradford, in the County of York, Manu-
facturers, and JAMES LAW and HIRAM MITCHELL, of the same Place,
Managers, do hereby declare the nature of the said Invention for "IMPROVE
MENTS IN MACHINERY FOR SPINNING AND DOUBLING," to be as follows:-
Our Invention is applicable to the spindles and caps or bells of machines
for spinning and doubling, and it consists in certain improved modes of con-
structing and lubricating the said spindles and the tube of the spool or
bobbin. The cap or bell is fixed to the upper end of a dead spindle, which
is grooved longitudinally or diagonally to convey the oil or other lubricating
material from a recess in the top of the cap or bell to the tube of the spool or
bobbin, the top of which is countersunk. The spindle is held securely in the
spindle. rail by making a countersunk recess in the spindle to receive the end

page_text: of the tightening screw, and the cap or bell is held in its proper position on
the spindle by means of a shoulder on the spindle, against which the boss of
the cap or bell abuts. By means of these improvements a great saving of
time, labor, and lubricating material is effected, and the power required for
driving the frames is also reduced.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Hastings, James Briggs, James Law, and Hiram
Mitchell in the Great Seal Patent Office on the 20th October 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHARLES
HASTINGS and JAMES BRIGGS, of the Firm of Messrs. Charles Hastings and
Company, of Bradford, in the County of York, Manufacturers, and JAMES
LAW and HIRAM MITCHELL, of the same Place, Managers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of April, 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 us, the said
Charles Hastings, James Briggs, James Law, and Hiram Mitchell, Her
special licence that we, the said Charles Hastings, James Briggs, James
Law, and Hiram Mitchell, our executors, administrators, and assigns, or such
others as we, the said Charles Hastings, James Briggs, James Law, and
Hiram Mitchell, our 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 SPINNING AND DOUBLING," upon the condition (amongst
others) that we, the said Charles Hastings, James Briggs, James Law, and
Hiram Mitchell, our executors or administrators, by an instrument in writing
under our, or their, or one of our or their hands and seals, should parti-
cularly 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 we, the said Charles Hastings, James Briggs,
James Law, and Hiram Mitchell, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to be particu-

page_text: larly described and ascertained in and by the following statement (that is to
say) :-
Our Invention is applicable to the spindles and caps or bells of machines
for spinning and doubling, and it consists in certain improved modes of con-
structing and lubricating the said spindles and the tube of the spool or bobbin.
The cap or bell is fixed to the upper end of a dead spindle, which is grooved
longitudinally or diagonally to convey the oil or other lubricating material
from a recess in the top of the cap or bell to the tube of the spool or bobbin,
the top of which cap or bell is countersunk.. The spindle is held securely in
the spindle rail by making a countersunk recess in the spindle to receive the
end of the tightening screw. By means of these improvements a great saving
of time, labor, and lubricating material is effected, and the power required for
driving the frames is also reduced.
And in order that our Invention may be fully understood and readily carried
into operation, we will proceed to describe the accompanying Sheet of Drawings,
reference being had to the figures and letters marked thereon.
Figure 1 is an elevation; Figure 2 a section; and Figure 8, a plan of
our improved machinery, which is particularly applicable for spinning and
doubling worsted.
a is one of our improved spindles which is supported in the bolster or
lifting rail and spindle rail c; these spindles are of the description
technically called "dead" spindles, that is to say, they do not revolve on
their axes, but each spindle is securely held in the spindle rail c by the
tightening screw d, the end of which instead of pressing against the round
surface of the spindle, as now customary, fits in the recess a¹, and consequently
prevents the spindle from turning round. The cap or belle is fixed to the
upper end of the spindle a in the usual manner, and the top of the cap or bell
is recessed or countersunk, as shewn in Figure 2. The spool or bobbin f fits
on the tube g loose on the spindle a, which is grooved longitudinally or
diagonally in order to distribute the lubricating material which is poured into
the recess at the top of the cap or bell, and flows into the groove to lubricate
the tube and the spindle. The tube g is cast or fixed to the wharle h, the
lower boss of which rests on the copping or lifting rail b, which is raised and
lowered in the ordinary manner to distribute the yarn over the surface of the
bobbin or spool.
By means of these improvements the spindles are held securely in the
spindle rails, and the lubricating material which is poured into the recess at
the top of the cap or bell is easy to apply, and is retained for a long time in
the groove of the spindle, thereby effecting a great saving in time, labor,

page_text: and lubricating material, and reducing the power requisite for driving the
frame.
Having thus stated the nature of our Invention, and described the manner
of performing the same, we declare that we claim,-
First, the recess a¹ in the spindles, for the purpose described.
Secondly, the recess or countersink in the top of the cap or bell, as
described.
And, lastly, the longitudinal or diagonal groove in the spindle to retain and
distribute the lubricating material..
In witness whereof, we, the said Charles Hastings, James Briggs,
James Law, and Hiram Mitchell, have hereto set our hands and
seals, this Seventeenth day of October, One thousand eight hundred
and sixty-six.
