Year: 1861

page_text: LETTERS PATENT to John Eastwood, of Bradford, in the County of York,
Machine Wool Comber, and John Barnett Joyce, of Bradford aforesaid,..
Machine Maker, for the Invention of "IMPROVEMENTS IN MACHINERY OR
PROVISIONAL SPECIFICATION left by the said John Eastwood and John
Barnett Joyce at the Office of the Commissioners of Patents, with their
Petition, on the 17th September 1861.
We, JOHN EASTWOOD, of Bradford, in the County of York, Machine Wool.
Comber, and JOHN BARNETT JOYCE, of Bradford aforesaid, Machine Maker,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES,"
to be as follows:-
"
The Invention relates to improvements in machinery or apparatus for which
Letters Patent were granted to John Henry Johnson, a communication to
him by Cullen Wipple, on the Twenty-sixth day of April One thousand eight
hundred and fifty-nine, and numbered 1050, in which the fibrous substances
are taken by nipping instruments from gill combs used to feed the wool, and.
the present improvement consists in forming and substituting a. vertical nip.

page_text: in place of the radial one which is used in the machinery above referred to.
This vertical nip, moving in vertical slides and actuated in a similar manner
to the already mentioned radial nip by a cam or cams, is in so far superior
to the said radial nip as it. considerably increases the productive power of the
machine.
SPECIFICATION filed in pursuance of the conditions of the Letters Patent,
and of an Order of the Lord Chancellor, by the said John Eastwood and
John Barnett Joyce in the Great Seal Patent Office on the 25th March
1862..
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, Jon
EASTWOOD, of Bradford, in the County of York, Machine Wool Comber, and
JOHN BARNETT JOYCE, of Bradford, aforesaid, Machine Maker, send greeting.
WHEREAS Her most, Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of September, in the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said John Eastwood and John Barnett Joyce, Iler special licence that we.
the said John Eastwood, and John Barnett Joyce, our executors, administrators,
and assigns, or such others as we, the said John Eastwood and John Barnett
Joyce, our 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 night 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 MACHI-
'NERY OR APPARATUS FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES," upon the
condition (amongst others) that we, the said John Eastwood and John Barnett
.Joyce, our executors or administrators by an instrument in writing under our,
or their, or one of their hands and scals, should particularly describe and as-
-certain 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 Officer
within six calendar months next and immediately after the date of tho said
Letters Patent.
NOW KNOW YE, that we, the said John Eastwood and John Barnett
Joyce, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, that is to say:

page_text: This invention relates to improvements in machinery or apparatus for which
Letters Patent were granted to John Henry Johnson, a communication to
him by Cullen Whipple, on the Twenty-sixth day of April, One thousand eight
hundred and fifty-nine, in which the fibrous substances are taken by nipping
instruments from gill combs used to feed the wool, and the present improvement
consists in forming and substituting a vertical nip in place of the radial one
which is used in the machinery above referred to. This vertical nip, moving
in vertical slides and actuated in a similar manner to the already mentioned:
radial nip by a cam' or cams, is in so far superior to the said radial nip as it
considerably increases the productive power of the machine.
;
In order to explain our said Invention as completely as possible, we now
proceed to describe the best means we are acquainted with for carrying the
same into practical effect, reference being had to the illustrative Sheet of Draw-
ings accompanying these Presents, and to the numeral figures and letters of
reference marked thereon respectively as follows:
DESCRIPTION OF THE DRAWING.
Figure 1 is a front elevation; Figure 2 a ground plan; and Figures 3 and
4 transverse and vertical sections of a vertical nip constructed according to
our said: improvements. At each of the foregoing Figures similar letters of
reference are employed to denote corresponding parts in so far as such parts
appear or can be seen at each of such said Figures respectively. A.marks the
body of the nip, forming the bottom jaw thereof; B, B, are slides on each side
of A upon which said jaw moves in suitable bearings; C is a rib formed on
A with lugs D, D, fixed to or formed thereon; E, E, are levers connected by
pins a, a, to. the lugs D, D, said pins being the fulcra of said levers. We
would here remark that the Drawing only exhibits two levers, but their num-
ber may be increased to suit circumstances. The rib C at each end has a
projection b, b, forming a vertical groove, or they may be V-shaped guides, in
which fits and slides vertically the top nip or jaw G, said jaw being grooved
along its bottom edge to fit over a corresponding projecting piece c, c, fixed in
the bottom jaw A as at Figures 1, 3, and 4. The top nip G is raised by a
spring or springs H, which press against pins d, d, fixed in G, or instead of
springs the top nip or jaw may be raised by a weight I, placed on a bar e,
the ends whereof rest on the ends of the levers which in this case must be
connected to the jaw G; the top jaw G is depressed by the levers E, which
are raised by the pieces K, K, fixed on the shaft L, which has motion
imparted thereto in the usual way.

page_text: Having now fully described and set forth the nature and object of our said
Invention of "Improvements in Machinery or Apparatus for Combing Wool
and other Fibrous Substances together with the best means we are acquainted
with for carrying the same into practical effect, we would remark in con-
clusion that we do not intend to limit or confine ourselves to the precise
details of construction above described and represented by the Drawing, as the
same may be varied. But what we claim as our Invention, intended to be
secured to us by the herein-before in part recited Letters Patent, is as follows:-
We claim adapting a vertical nip to a machine for which Letters Patent
for the United Kingdom, bearing date the Twenty-sixth day of April, One
thousand oight hundred and fifty-nine, numbered 1050, were granted to John
Henry Johnson for an Invention of "Improvements in Machinery or Appa-
ratus for Combing Wool and other Fibrous Substances," communicated to
the said John Henry Johnson by Cullen Whipple, of the City and County
of Providence, in the State of Rhode Island, United States of America, and
the substituting of said vertical nip in place of the radial nip described and
referred to in the Specification of the aforesaid Patent, of tho Twenty-sixth
April, 1859, as constituting improvements in machinery or apparatus for
combing wool and other fibrous substances, whereby a considerably greater
quantity of the fibrous substanco can be combed in a given time than by the
use of the radial nip above referred to.
In witness whereof we, the said John Eastwood and John Barnett Joyce,
have hercunto set our hands and seals, this Twenty-first day of March,
in the year of our Lord One thousand eight hundred and sixty-two.
