page_text: LETTERS PATENT to Henry Kilshaw, of Haslingden,. in the County of
Lancaster, Cotton Spinner and. Manufacturer, and Thomas Elce, junior, of
the City of Manchester, Machine Maker, for the Invention of " CERTAIN
Sealed the 21st August 1863, and dated the 21st February 1863.
PROVISIONAL SPECIFICATION left by the said Henry Kilshaw and
Thomas Elce, at the Office of the Commissioners of Patents, with their
Petition, on the 21st February 1863.
We, HENRY KILSHAW, of Haslingden, in the County of Lancaster, Cotton
Spinner and Manufacturer, and THOMAS ELCE, junior, of the City of Man-
chester, Machine Maker, do hereby declare the nature of the said Invention
for CERTAIN IMPROVEMENTS IN MACHINERY FOR PREPARING AND DOUBLING COTTON
AND OTHER FIBROUS SUBSTANCES," to be as follows:-
Our Invention is applicable to the machines for preparing, known, as
intermediate frames, roving frames, and jack frames, and to doubling frames,"
and it consists in applying to such machines an additional pair of rollers placed
at the back of the drawing rollers. Between this additional pair of rollers
and the back drawing roller a series of hooks are inserted, and each roving or
yarn passes under one of these hooks; as long as the rovings or yarns con-
tinue to be supplied the hooks are held up, but as soon as a roving or yarn
breaks or fails to be supplied, the hook under which it had been pressing drops,
and comes in contact with a feeler fixed on a shaft revolving beneath the
hooks, or with a vibrating knife or bar, this feeler or bar being stopped by
the hook arrests the shaft, and by means of the ordinary mechanism now.

by the said Henry Kilshaw and Thomas Elce, in the Great Sea
Patent Office on the 21st August 1863,
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
KILSHAW, of Haslingden, in the County of Lancaster, Cotton Spinner and
Manufacturer, and THOMAS ELCE, jun., of the City of Manchester, Machine
Maker, send greeting,
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of February, in the year of our
Lord One thousand eight hundred and sixty-three, in the twenty-sixth year of
Her reign, did for Herself, Her heirs and successors, give and grant unto us,
the said Henry Kilshaw and Thomas Elce, Her special license that we, the
said Henry Kilshaw and Thomas Elce, our executors, administrators, and
assigns, or such others as we, the said Henry Kilshaw and Thomas Elce,
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 "CERTAIN IMPROVEMENTS IN
MACHINERY FOR PREPARING AND DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES,"
upon the condition (amongst others) that we, the said Henry Kilshaw and
Thomas Elce, 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 Henry Kilshaw and Thomas Elce,
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 applicable to the machines for preparing, known as inter-
mediate frames, roving frames, and jack frames, and to doubling frames, and
it consists in applying to such machines a self-acting apparatus, by means

page_text: whereof the machine 18 stopped when an end breaks, or when the supply
ceases.
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.
Figure 1 is a transverse section of part of an intermediate frame to which
one mode of constructing our improvements is applied; Figure 2 is an
elevation; and Figure 3, a plan of the same. a, are the fluted drawing
rollers; b, the stand; c, the roller beam; d, the driving pulleys; e, the strap
fork; f, the sliding rod to which the strap fork is fixed; 9, the starting rod;
h, the starting lever; and i, the catch for holding the lever h in its place by
means of the latch t¹, the parts above enumerated, and all the others requisite
to complete the machine, which are not particularly referred to hereafter, are
made in the usual manner; j is an additional roller furnished with a top
roller k placed at the back of the usual drawing rollers a, between the addi-
tional rollers and k a series of hooks or spoons are mounted, and each
roving passes over one of these spoons which are prevented from falling over
by the rail m; to each spoon is jointed a short pendent arm l', under which is
the shaft n provided with feelers n', this shaft n has a vibrating motion
imparted to it, as in drawing frames, by the eccentric o which is loose on the
shaft p of the upper cone, but connected to it when required by the sliding
clutch box p', which is moved to and fro on the shaft p by the lever qg, whose
upper end passes between shoulders fixed to the sliding rod f. The eccentric o
has a clip passing round it connected by the link o¹ to the crank pin pro-
jecting from the boss o², which is connected to the shaft n by a pin passing
through the boss o³, and fitting in an inclined recess in a bush fixed to the
shaft n. Near to the boss o² is a flange o³, which fits against the bush o'
loose on the shaft n, in this bush is a groove to receive the forked end of the
rod g', the other end of which is jointed to the upper arm of the elbow lever q³.
The horizontal arm of this elbow lever is connected to the latch by the
link 9. The mode of operation is as follows:-So long as the rovings con-
tinue to be supplied, the spoons are held in the position shewn in Figure 1,
that is to say, they are pressed against the rail m, and the pendent arms l¹ are
held up to allow the feelers n¹ to pass freely to and fro under them, but as
soon as a roving breaks or ceases te be supplied, the spoon over which it had
been passing falls back towards the rollers j and k, and the pendent arm l
projects downwards, so that when the feeler n' comes against it, the vibrating
motion of the shaft n is arrested; the pin in the boss o³ (which continues its
vibrating motion after the shaft n is stopped) then slides along the inclined

page_text: recess in the bush fixed to the shaft n, thereby causing the boss o², the
washer o, and the bush o' to move towards the stand b, the rod q is thus
moved in the direction of the arrow, and the horizontal arm of the elbow
lever is raised, thereby unlatching the latch ', which is drawn back by a.
spring or weight in the direction of the arrow upon it, by this means the
upper end of the starting lever h is brought against the stud g' fixed to the
starting rod 9, which moves the sliding rod f and strap fork e to traverse the.
driving strap from the fast. to the loose pulley, thus stopping the machine.
The sliding of the rod f to stop the machine, also disconnects the clutch-
box p' from the clutches on the boss of the eccentric o. When the attendant
has pieced up the broken end, the driving strap is brought again on the fast
pulley in the usual manner, and the various parts regain the positions shewn
in the Drawing.
Under
Figure 4 represents a modification of our Invention drawn full size. In
this view the rovings after passing between the rollers; and k pass under
the hooks s, which fit easily in holes in the rail t, the rovings then pass over:
the additional roller, and thence to the ordinary drawing rollers a.
the rail t is the vibrating shaft n, with feelers n¹. As long as the rovings
continue to be supplied, the hooks & are held up by the rovings, but as soon
as a roving breaks or ceases to be supplied, the hook drops, and the end pro-
jecting through the rail t, arrests the feeler n¹ and shaft n, thus stopping the
machine in the manner above described. The improvements above described
and shewn as applied to an intermediate or roving frame are also applicable
to jack frames and to doubling frames.
Having thus stated the nature of our Invention, and described the manner
of performing the same, we declare that we claim the application of a self-
acting apparatus for stopping intermediate frames, roving frames, jack frames,
and doubling frames, when the roving or yarn with which such frames are fed
ceases to be supplied.
In witness whereof, I, the said Thomas Elce, junior, have hereto
set my hand and seal, this Eighteenth day of August, in the
year of
our Lord One thousand eight hundred and sixty-three.
THOMAS ELCE, JUN³. (L.S.)
