Year: 1870

page_text: LETTERS PATENT to George Little, of Oldham, in the County of
Lancaster, Mechanical Engineer, for the Invention of "IMPROVE-
MENTS IN MACHINERY FOR COMBING COTTON, WOOL, AND
MATERIALS."
OTHER. FIBROUS
Sealed the 5th July 1870, and dated the 8th January 1870.
PROVISIONAL SPECIFICATION left by the said George Little at the
Office of the Commissioners of Patents, with his Petition, on the
8th January 1870.

I, GEORGE LITTLE, of Oldham, in the County of Lancaster, Mechanical
Engineer, do hereby declare the nature of the said. Invention for "Im-
PROVEMENTS IN MACHINERY FOR COMBING COTTON, WOOL, AND OTHER FIBROUS
MATERIALS," to be as follows:—
J
My Invention relates to machines which are constructed upon what
is commonly known as the Heilmann principle. In this known arrange-
ment there is a shaft carrying a cam which causes another shaft for
actuating the nippers to vibrate upon its centre, and it is to the method
of giving motion to this second shaft that my Invention refers, the

page_text: principle being that I “ square "the said shaft and avoid torsion by
imparting motion to it at more than one place.
The method by which I propose to carry out my Invention is to
continue the cam shaft from one end framing to another, and to adapt
a cam at each end thereof for causing the nipper shaft to vibrate; or
more than two cams may be employed if desired.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Little in the Great Seal Patent Office on
the 8th July 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
LITTLE, of Oldham, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth January, One thousand eight
hundred and seventy, in thirty-fourth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said
George Little, Her special license that I, the said George Little, my
executors, administrators, and assigns, or such others as I, the said
George Little, 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 MACHINERY FOR COMBING COTTON, WOOL, AND OTHER
FIBROUS MATERIALS," upon the condition, amongst others, that I, the
said George Little, 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 George Little, 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

page_text: the following statement (and accompanying Drawings), that is to
say:-
My Invention relates to machines which are constructed upon what
is commonly known as the Heilmann principle. In this known arrange-
ment there is a shaft carrying a cam which causes another shaft for
actuating the "nippers" to vibrate upon its centre, and it is to the
method of giving motion to this second shaft that my Invention refers..
In the accompanying Drawing, Fig. 1 represents in front elevation a
portion of a combing machine on the said Heilmann principle, but
constructed according to my Invention; Fig. 2 is a cross section of the
same. And in order fully to explain the application of my Invention I
will in the first place allude to some of the known parts.
The nipper bars are at a, and the nippers at 6, mounted upon levers c;
to which are jointed the rods d, connected at their other ends to levers e
mounted upon the shaft f. Upon this shaft is also the lever g, which
by means of set screws h acts upon the lever i attached to the shaft f.
The lower end of the lever i carries a bowl k situate within a grooved
cam 1, whereby the shaft f is caused to vibrate and impart motion to
the nippers b. This is the ordinary arrangement, and according to
which the cam is mounted upon a shaft m which is discontinued
at m*.
According to one arrangement of my Invention instead of thus dis-
continuing the shaft m I carry it across the width of the machine, and
place on its other end a second cam * of the same form as that shewn
at 1, and acting upon another lever i* upon the shaft f, and which after
the manner of that on the other side of the machine gives motion to
the lever and consequently to the nipper shaft f. It will thus be
seen that motion is communicated to the shaft ƒ at both ends thereof,
by which it becomes what is technically called "squared" and torsion
thereof is avoided, so that the nippers are caused to act more equally
through their series.
Instead of the exact arrangement above described one or more cams
with their corresponding levers may be placed at any required distances
apart between the two end cams 1, 1*, so as to impart motion to the
nipper shaft at more than two places. Also, if desired, the nipper shaft
may be made in two portions in the direction of its length, the shaft m
being provided with cams to act upon each end of such portions.

page_text: .
Fig. 3 shews a further modification of my Invention. In this instance
two cams n, n*, are placed upon a short shaft o, and acting upon levers
p, p*, the former of which gives motion to the nipper shaft q through
the intervention of a lever as as usual, but in this case the said shaft
terminates at q, and gives motion to a portion only of the series of
nippers, the remainder being actuated by a shaft s which passes through
the the first-mentioned shaft q and is provided at its outward end with
levers t, p*, connected to the second cam n*. Both of these nipper shafts
therefore turn together, but by the employment of the two cams the
work is divided between the two shafts q, s, and the tendency to torsion
is decreased.
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 for the purposes above set forth and in reference
to such machines as aforesaid, the use of two or more cams for giving
motion the nipper shaft.

In witness whereof, I, the said George Little, have hereunto set my
hand and seal, this Seventh day of July, in the year of our Lord
One thousand eight hundred and seventy.
