PROVISIONAL SPECIFICATION left by the said William Terry and John
Scott at the Office of the Commissioners of Patents on the 22nd December
1882.
WILLIAM TERRY and JOHN SCOTT of Dudley Hill near Bradford in the
County of York Commission Wool Combers "IMPROVEMENTS IN MACHINERY
OR APPARATUS FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES
"
This Invention relates to improvements in the method of and apparatus for
feeding tufts of wool on to a circular comb. For this purpose we employ a
reciprocating gill head placed outside the circular comb the gill combs placed
outside the circular comb the gill combs or "fallers" being curved to the same
radius as the inner row of teeth in the circle and placed at a higher level than the
circle so as to be capable of advancing over the whole width thereof. In the
interior of the circular comb wo employ a pair of nipping jaws which are opened
and closed as the gill head reciprocates to draw off a tuft of wool from the gill
combs, the jaws are then lowered and the tuft deposited upon the circular comb
and dabbed therein by a brush in the usual manner.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Willian Terry and John Scott in the Great Seal Patent Office
on the 22nd June 1883.
WILLIAM TERRY and JOHN SCOTT of Dudley Hill near Bradford in the
County of York, Commission Wool Combers "IMPROVEMENTS IN MACHINERY
OR APPARATUS FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES"
This Invention relates to improvements in the method of and apparatus for
feeding tufts of wool onto a circular comb. For this purpose we employ a
reciprocating gill head placed outside the circular comb, the gill combs or "fallers"
being curved to the same radius as the inner row of teeth in the circle and placed
at a higher level than the circle so as to be capable of advancing over the whole
width thereof. In the interior of the circular comb we employ a pair of nipping
jaws which are opened and closed as the gill head reciprocates to draw off a tuft
of wool from the gill combs, the jaws are then lowered and the tuft deposited upon
the circular comb and dalbed therein by a brush in the usual manner.
In order that our Invention may be more fully understood we herein give
reference to the accompanying sheets of drawings, illustrative thereof. Fig 1 is
sectional elevation of those parts of a circular comb and feeding apparatus necessary
to illustrate our improvements and Fig 2 is a plan view of such parts. Fig 3 is a
detail. A is the framework of the machine upon which are mounted the large and
small circular combs B and C-and the reciprocating gill head D the operation of
which is well known and of which a description is given in the Specification of
Patent granted to us, dated the 13th of October A.D. 1881 N° 4464.
In carrying out our present Invention we have found it convenient in order to
reduce the travel of the nipping jaws to invert the ordinary arrangement of the
gill fallers that is to say we place the combing series underneath with the points
downwards and cause them to advance over the whole width of the comb circle.
E and Fare a pair of nipping jaws which are hinged together at a and are carried
by a vertical sliding bar G working through box G¹ to the bottom of which bar
are attached two rods H connected at their upper ends to lever arms J between
which is a friction bowl L resting upon a cam M mounted upon a shaft N and
caused to revolve by toothed wheels 1 and 2, the former of which is mounted on
the driving shaft 3. As the cam revolves the nipping jaws are caused to rise and
fall vertically and have no other movement beyond that of opening and closing
which is effected as follows. The pillars O support two lever arms P which carry
a bowl P¹ and are connected from their opposite ends by means of rod P2 to the
bottom of the sliding bar G. To the back edge of the lower jaw is attached the
upright b to the top of which is hooked a spiral spring c which is also fastened
to the upper nipping jaw. On the ends of the lower jaw are hinged catches d
(See Fig 3) the lower ends of which are bent inwards and to the upper ends of
which are attached springs e. In the drawings the jaws are shewn closed and the
gill head is receding and leaving a tuft of wool between the jaws. As the cam M
revolves the jaws will descend and deposit the tuft upon the comb B and when
at about its lowest point the ends f of the catches & will strike upon studs g
and release the upper jaw which is then raised by the spring c and the tuft is
released
It will be seen from the drawings that as the jaws and sliding bar G fall, the
bowl P¹ must rise and on the jaws and bar rising the bowl falls, pressing upon and
closing the upper jaw as soon as the gill head reaches the full extent of its forward
movement and places the end of the tuft between the jaws which then close and
are locked by the spring catches d. The amount of pressure exercised upon the

page_text: ጥ
nipping jaws is regulated by the spiral spring p which bears upon the collar and
against the square stud & through which the rod P³ passes.
As the tufts are deposited upon the comb they are dabbed into the teeth thereof
by an ordinary dabbing brush, the action of which is so well known that we have
not thought it necessary to illustrate it.
Having thus described the nature of our Invention and shewn by Drawings
how the same is to be performed, we would have it understood that we claim-
Firstly. A pair of nipping jaws, working within a circular comb, having a
vertical rising and falling motion only, substantially as and for the purpose herein
shewn and described.
Secondly. The method of and apparatus for opening, closing and locking the
jaws substantially as herein shewn and described.
Thirdly. The use of the parts H. J. L and M for raising and lowering the sliding
bar and jaws substantially as herein shewn and described.
Fourthly. The arrangement of a reciprocating gill feeding-head in combination
with a pair of nipping jaws working within the comb circle, substantially as herein
shewn and described.
In witness whereof we the said William Terry and John Scott have hereunto
set our hands and seals this sixteenth day of June, in the year of our Lord,
One thousand eight hundred and eighty three.
