IMPROVEMENTS IN CERTAIN MACHINES FOR PREPARING COTTON AND OTHER FIBROUS MATERIALS
Year: 1859

page_text: LETTERS PATENT to Robert Tempest and James Tomlinson, both of the
Roach Iron Works, Rochdale, in the County of Lancaster, Machine
Makers, for the Invention of "IMPROVEMENTS IN CERTAIN MACHINES FOR
PREPARING COTTON AND OTHER FIBROUS MATERIALS."
Sealed the 8th March 1859, and dated the 3rd January, 1859.
PROVISIONAL SPECIFICATION left by the said Robert Tempest and James
Tomlinson at the Office of the Commissioners of Patents, with their
Petition, on the 3rd January 1859.
We, ROBERT TEMPEST and JAMES TOMLINSON, both of the Roach Iron Works,
Rochdale, in the County of Lancaster, Machine Makers, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN CERTAIN MACHINES FOR
PREPARING COTTON AND OTHER FIBROUS MATERIALS," to be as follows:-
Our Invention is particularly applicable to drawing frames, and consists in
an improved combination of parts by which the machine is stopped when' the
sliver breaks between the drawing rollers and the calender rollers. The catch
lever to which the spout or trumpet mouth is fixed is jointed between its
fulcrum and the calender rollers, so that when the sliver breaks the lever with
the spout or trumpet mouth can easily be raised to facilitate the removing of
the knot or other impurity which caused the sliver to break.¨¨

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Tempest and James Tomlinson in the Great Seal
Patent Office on the 1st July 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ROBERT
TEMPEST and JAMES TOMLINSON, both of the Roach Iron Works, Rochdale, in
the County of Lancaster, Machine Makers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of January in the year of our Lord One
thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Robert Tempest and James Tomlinson, Her special licence that we, the
said Robert Tempest and James Tomlinson, our executors,, administrators, and
assigns, or such others as we, the said Robert Tempest and James Tomlinson,
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 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
CERTAIN MACHINES FOR PREPARING COTTON AND OTHER FIBROUS MATERIALS," upon
the condition (amongst others) that we, the said Robert Tempest and James
Tomlinson, our executors or administrators, by an 'instrument in writing under
our, or their, or one of our or their hands and seals, 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 we, the said Robert Tempest and James Tomlinson,
do hereby declare the nature of our said Invention, and in what manner.
the same is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say) :-
Our Invention is particularly applicable to drawing frames, and .consists.in
an improved combination of parts by which the machine is stopped when the
sliver breaks between the drawing rollers and the calender rollers.
."

page_text: The catch lever to which the spout or trumpet mouth is fixed is jointed
between its fulcrum and the calender rollers, so that when the sliver breaks;
the lever with the spout or trumpet mouth can easily be raised to facilitate the
removing of the knot or other impurity which caused the sliver to break.
Our Invention also consists in making an open spout instead of a circular
trumpet mouth to guide the sliver to the calender rollers.
But that the nature of these our improvements and the means we adopt in
carrying the same into effect may be fully understood, we will proceed to
describe the accompanying Sheet of Drawings, reference being had to the
figures and letters marked thereon.
Fig. 1 is a plan of part of a drawing frame to which our improvements are
applied; Fig. 2 is an elevation of the same; Fig. 3 is a detached view of
part of the same, shewing our improvements combined with a trumpet mouth
instead of an open spout as shewn in Fig. 2. a, a, are the drawing rollers;
b, b, the calender rollers; c, the spoons or guides for the slivers, which are
indicated by a dotted line in Fig. 2; and d, the rocking shaft, with feelers d';
these parts are all made in the usual manner. The catch lever e is supported
by the stand f, and it is hooked at one end and furnished with a guide at the
other; but instead of making the lever solid, it is jointed at g between its
fulcrum and the calender rollers, so that when the sliver breaks the jointed
end of the lever with the trumpet mouth, as shewn at Fig. 3, or the open
spout h, shewn in Figs. 1 and 2, can easily be raised into the position indicated
by dotted lines in Fig. 2, to facilitate the removal of the knot or other impurity
which caused the sliver to break, and to enable the attendant to pass the end
of the sliver through the guard over the calender rollers; the object of making
the guide above the calender rollers of the shape of an open spout instead of a
circular trumpet mouth is also to facilitate the piecing up when a sliver has
broken. The mode of operation is similar to that of drawing frames, having stop
motions of the ordinary construction, that is to say, the sliver in passing
through the trumpet mouth or spout h, keeps the hooked end of the lever e
above the feeler don the vibrating shaft d, but as soon as the sliver breaks
between the drawing rollers and the calender rollers, the hooked end of the
lever drops on to the feeler and the driving strap is moved from the fast to the
loose pulley in the usual manner.
Having thus stated the nature of our Invention, and described the manner
of performing the same, we declare that we claim as of our Invention,―
First, the application of a hinge to the catch lever forming part of the stop
motion of a drawing frame, the said catch lever being furnished either with a
trumpet mouth of the usual construction, or with an open spout.

page_text: And, secondly, substituting an open spout for the trumpet mouth usually
employed for guiding the sliver to the calender rollers of drawing frames.
In witness whereof, we, the said Robert Tempest and James Tomlinson,
have hereunto set our hands and seals, this Thirtieth day of June, in
the year of our Lord One thousand eight hundred and fifty-nine.
ROBERT TEMPEST. (L.B.)
JAMES TOMLINSON. (L.S.)
