Year: 1876

page_text: LETTERS PATENT to Daniel Smith and Isaac Bailey, of Keighley, in the
County of York, Commission Wool Combers, for the Invention of "IM-
PROVEMENTS IN MACHINERY FOR COMBING WOOL AND OTHER FIBROUS
SUBSTANCES."
Sealed the 16th September 1876, and dated the 23rd March 1876.
PROVISIONAL SPECIFICATION left by the said Daniel Smith and Isaac
Bailey at the Office of the Commissioners of Patents on the 23rd March
1876.

inission Wool Combers. "IMPROVEMENTS IN MACHINERY FOR COMBING WOOL AND
OTHER FIBROUS SUBSTANCES."
"
This Invention relates to what are known as Lister's nip combs, and our
improvements consist in the employment of apparatus for cleaning the jaws of the
nip." For this purpose we fix a pendulous arm or rod to the head of the nip,
the length of the same being equal to the radius of the circle of which the jaws
are a segment, and on the lower end of this arm are rubbers for removing the fibres
from the edges of the nipping jaws. These rubbers are thrown or drawn across the
nip as often as required by cams and levers arranged and actuated similarly to the
treading" or "picking" motion of a loom, which is well understood.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said Daniel Smith and Isaac Bailey in the Great Seal Patent Office on the
23rd September 1876.

This Invention relates to what are known as Lister's" or "nip combs," and
our improvements consist in the employment of apparatus for cleaning the jaws of
the "nip." For this purpose we fix a pendulous arin or rod to the head of the nip,
the length of the same being equal to the radius of the circle of which the jaws

or fibres from the edges of the nipping jaws, These rubbers are thrown or drawn
across the "nip" as often as required by cams and levers arranged and actuated
similarly to the treading" or picking" motion of a loom, which is well under-
stood.
"
In order that our Invention may be more fully understood we herein give
reference to the accompanyin Sheet of Drawings marked with figures and letters
of reference.

Fig. 1 is a front elevation of such parts of a gill head or nip" as are necessary
to illustrate our Invention. A and B are the nipping jaws, which are worked in the
usual manner. The sides of the "nip" are carried upwards, and form an arch over
the jaws, in the centre of which arch we hinge an arm C, the length of this arm being
equal to the radius of the circle of which the jaws are segments. A detail of the bottom
portion of this arm is shewn in Fig. 3, where it will be seen that a groove lined with
leather or other flexible rubber a is provided to receive the edge of the upper jaw.
The arm continued downwards terminates in a slot containing a spiral spring which
presses another cleaner D into the groove of the lower jaw. Both the top and
bottom jaws are cleaned by the rubbers being caused to pass across them when open,
which is effected by the rising and falling motion of the rod E acting upon the
bent lever F and rod G connected to the arm C. The rising and falling motion is
effected by a cam H (see detail, Fig. 2), which acts on the bowl J of the lever K,
the other end of which passes through a swivel boss L fixed to the arm E. As the
arm E oscillates with the nipping jaws the end of the arm is provided with a
slot M, which admits of the oscillation, and also the rising and falling motion
derived from the cam.
Having thus fully described the nature and particulars of this our said Invention,
together with the manner in which the same is to be performed or carried into
practical effect, we would have it understood that we claim as our Inven-
tion ―
The combination and arrangement of apparatus for cleaning the nipping jaws of
combing machines, substantially as herein shewn and described.
In witness whereof, I, the said Isaac Bailey, for and on behalf of myself and
the said Daniel Smith, have hereunto set my hand and seal, this Eighteenth
day of September, in the year of our Lord One thousand eight hundred
and seventy-six.
