Year: 1860

page_text: LETTERS PATENT to Robert Tempest and James Tomlinson, both of the
Roach Ironworks, Rochdale, in the County of Lancaster, Machine
Makers, for the Invention of "IMPROVEMENTS IN CERTAIN MACHINES FOR
PROVISIONAL SPECIFICATION left by the said Robert Tempest and James
Tomlinson at the Office of the Commissioners of Patents, with their
Petition, on the 18th August 1860.
.. We, ROBERT TEMPEST and JAMES TOMLINSON, both of the Roach Ironworks,
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:-
The first part of our Invention is applicable to the drawing heads of carding
engines, to drawing frames, slubbing frames, and roving frames, and it consists
in an improved combination of parts for stopping the machinery when the
sliver or roving breaks between the drawing rollers and the calendar rollers, or
between the drawing rollers and the bobbin or spool.

page_text: In performing our Invention we apply a double catch to the balanced catch
lever, to which the spout or trumpet mouth is connected.. This double catch
when the sliver or roving fails, comes in contact with the feeler, mounted as
usual on the rocking shaft. This shaft is furnished with a saw catch box,
connected either in the usual manner to the strap guide by which the driving
strap is moved from the fast to the loose pulley, or to any other combination
of machinery for arresting the motion of the machine, or of parts of the
machine to which our improved stop motion is applied. By means of this
double catch the machinery is stopped more suddenly than was heretofore
possible, thereby preventing or diminishing waste.
Another part of our Invention consists in applying a guide slot to the
bearing for the balanced catch lever of front stop motions, to render such
levers easy of action and steady.
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 15th February 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, 'ROBERT
TEMPEST and JAMES TOMLINSON, both of the Roach Ironworks, Rochdale, in
the County of Lancaster, Machine Makers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of August, in the year of our Lord One
thousand eight hundred and sixty, in the twenty-fourth 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

page_text: 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):-
The nature of our Invention, which is applicable to drawing frames, slubbing
frames, and 'roving frames, consists in an improved combination of parts for
stopping the machinery when the sliver or roving breaks between the drawing
rollers and the calendar rollers, or between the drawing rollers and the bobbin
or spool.
In performing our Invention we apply a double catch to the balanced catch
lever to which the spout or trumpet mouth is connected; this double catch
when the sliver or roving fails comes in contact with the feeler, mounted as
usual on the rocking shaft; this shaft is furnished with a saw catch box
connected in the usual manner to the strap guide, by which the driving strap
is moved from the fast to the loose pulley. By means of this double catch the
machinery is stopped more suddenly than was heretofore possible, thereby
preventing or diminishing waste.
Our Invention consists, also, in applying a guide slot to the bearing for the
balanced catch lever of front stop motions, to render such levers easy of action
and steady.
: .
And in order that our Invention may be fully understood and readily
carried into effect,' we will proceed to describe the accompanying. Sheet of
Drawings, reference being had to the figures and letters marked thereon.
Fig. 1. is an elevation of a part of a drawing frame to which our improve-
ments are applied; and Fig. 2 is 'a plan of the same. a, a, are the drawing
rollers; b, b, the calender rollers; c, the roller beam; d, the rocking shaft, and
the plate to which the spools or guides for the slivers to pass thro'
are connected in the usual manner; e is the balanced catch lever, which is
supported by the stand f, and jointed at g to the trumpet mouth g¹ in the
manner described in the Specification of Letters Patent granted to us on the
Third day of January, One thousand eight hundred and fifty-nine; 'No. 25.
The lever e instead of being hooked at the end as formerly customary; is pro-
vided with the double catch e', the position of which is capable of being

page_text: The feelers d², shewn by dots in
which is put in motion in the
adjusted by a set screw, as shewn in Fig. 2.
Fig. 1, are fixed to the rocking shaft d,
usual manner by the lever d and connecting link d', one end of which
is jointed to a stud in the pinion a' fixed to the end of the third roller. The
lever d³ is cast with the half of a saw catch box, and is loose on the shaft d;
the other half of the catch box marked i is fast to the shaft d, as shewn best
in Fig.2. The elbow lever is acted upon by the lever d³, and serves as a
catch to the rod d³, which is in communication with the starting rod and strap
fork guide, as in drawing frames of the usual construction. The rocking shaft
d is also provided with the ordinary feelers for the spoons connected to the
plate d³, but these spoons and feelers are not shewn in the Drawing. The
stand fis made with a long guide slot for the levere to work in, and near each
end of the slot is a regulating set screw on which the lever e bears. The mode
of operation is as follows:-When the frame is at work the sliver indicated by
the dotted line h in Fig. 1, passing thro' the trumpet mouth g¹ holds the double
catch above the feeler d, which then passes to and fro under the said
double catch; but as soon as the sliver-breaks or ceases to pass thro' the
trumpet mouth, the double catch drops on to the feeler d³, and consequently
holds the shaft & still. The lever d³ continues its motion between the limits
indicated by the lines A, B, in Fig. 1, after the shaft & has been stopped, and
this motion of the lever, combined with the fixed saw catch i, forces the two
parts of the catch box asunder, that is to say, causes the lever d³ to slide along
the shaft d in the direction of the arrow in Fig. 2, and at the same time
causes the elbow lever 7 to liberate the rod d³, and thus to move the starting
rod until the driving strap is on the loose pulley.
It will be evident from the foregoing description and Drawing, that the
machinery will be stopped more suddenly than heretofore owing to the double
catch & and the double-action of the saw catch box i, which liberates the catch
lever in whichever direction the lever may be moving. By this means the
quantity of waste is reduced, and the guide slot in the stand f renders the
the action of the lever e more accurate than was attainable in the stands of
the usual construction.
We wish to remark, that our Invention is also applicable to slubbing and
roving frames.
Having thus, stated the nature of the Invention, and described the manner
of performing the same, we declare that we claim,-
First, the double catch e¹ when used in the manner and for the purposes
described.

page_text: Secondly, the combination of the saw catch box i with the double catch e',
as described.
And, thirdly, the constructing the stand f of the balanced catch lever e with
a guide slot, as described.
In witness whereof, we, the said Robert Tempest and James Tomlinson,
have hereunto set our hands and seals, this Thirteenth day of
February, in the year of our Lord One thousand eight hundred and
sixty-one.
