Year: 1854

page_text: LETTERS PATENT to Robert Caunce, of Bolton-le-Moors, in the County of
Lancaster, Cashier, for the Invention of "CERTAIN IMPROVEMENTS IN
Sealed the 13th February 1855, and dated the 16th August 1854.
PROVISIONAL SPECIFICATION left by the said Robert Caunce at the
Office of the Commissioners of Patents, with his Petition, on the 16th
August 1854.
J, ROBERT CAUNCE, of Bolton-le-Moors, in the County of Lancaster,
Cashier, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN MACHINERY FOR PREPARING COTTON AND OTHER FIBROUS MATE-
RIALS to be as follows:-
The nature of my Invention consists in the application to roving frames and
other machines of the like nature of certain machinery, whereby any single
spindle and bobbin may be stopped for piecing up the ends, or for other pur-
poses, while the remainder of the bobbins and spindles continue to work; by
this means a considerable saving in time is effected, as at present the whole
frame is generally stopped during the time that any single bobbin is stopped
for piecing or other purposes. My improvements are carried into effect by
disconnecting catch boxes on the shafts for driving the spindles and bobbins.
When a roving breaks between the front roller and the bobbin, it is requisite
to break the roving between the traverse rail and the back roller to prevent
waste. When the piecing has been effected, and the bobbin that had been

page_text: stopped is again ready for starting, the catch boxes are put into gear with the
catches on the wheels driving the spindle and bobbin. By this means any
individual bobbin may be stopped and again started, while the remainder of
the bobbins continue their work.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Caunce in the Great Seal Patent Office on the 15th
February 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
CAUNCE, of Bolton-le-Moors, in the County of Lancaster, Cashier, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of August, in the year of our Lord
One thousand eight hundred and fifty-four, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Robert Caunce, Her special license that I, the said Robert Caunce,
my executors, administrators, and assigns, or such others as I, the said Robert
Caunce, my 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 COTTON AND OTHER FIBROUS MATERIALS," upon the condition
(amongst others) that I, the said Robert Caunce, by an instrument in writing
under my hand and seal, 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. I, the said Robert Caunce, do hereby declare the
nature of my 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 my Invention consists in the application to roving frames and
other machines of the like nature used in preparing cotton and other fibrous
materials of certain improved machinery, whereby any single spindle and
bobbin may be stopped and again started without stopping the entire machine;

page_text: and in order that my Invention may be fully understood and readily carried
into effect, I will proceed to describe the means pursued by me, reference being
had to the accompanying Drawing, and to the figures and letters marked
thereon.
DESCRIPTION OF THE DRAWING.
Figure 1 is a sectional elevation of a machine for winding fine rovings on
to bobbins, commonly called a "jack frame," to which my improvements are
applied; Figure 2 is a front view; and Figure 3, a plan of part of the same.
In these views a, a, are the spindles; b, the bobbins; c, the skew bevel pinions,
driven by the wheels d and shafts d', for giving motion to the bobbins b; f, the
skew bevel pinions, driven by the wheels g and shafts g', for giving motion to
the spindles a; h is the stationary bottom rail; and i, the moveable top rail by
which the spindles are supported in the usual manner. The foregoing parts,
and others not shewn in the Drawing, are similar to those in "jack frames"
of the ordinary construction. In my improved frame the pinions f are not
keyed on the spindles a, but they are connected to them by the clutch boxes f¹,
which slide upon fixed keys let into the spindles, and the pinions c are con
nected to the plates on which the bobbins rest by the clutch boxes c¹, cast on
the lower parts of the said plates. To the upper rail i are fixed two brackets i¹,
between which the rails and are supported; from the lower rails >² project
inclined surfaces , which act upon inclined notches in the upper rails ;
there are also similar brackets and rails with inclines, marked h¹, h², h³, and h*,
connected to the bottom rail h. The upright shaft k works below, through a
swivel socket in the bottom rail h, and above it passes through a bearing in
the moveable rail i. To this shaft is fitted below a double lever k¹, each arm
of which takes into a fork at the under side of the rail h²; near the upper part
of the shaft is fixed another double lever k², taking into forks in the rails i².
To the shaft k is fixed a catch piece ³, the longer end of which bears on the
stop plate 1, fixed to a bracket bolted to the moveable rail i; to the stop plate
lis hinged the trigger l', the object of which will be explained hereafter. The
rails and h³ are furnished with guide bushes, through which pass the pins
23 and h³. These pins enter into the grooves formed in the clutch boxes
c' and f', and those for the back row of spindles are sufficiently long to pass
through both the rails and h³; only four of these pins are shewn in Figure 3,
as they can easily be taken from the bushes in which they are shewn, and
inserted into those near the spindle and bobbin to be stopped. The mode of
operation is as follows:-As long as all the spindles continue to work the
various parts remain in the positions they occupy in Figure 2, and in the left
hand spindle of Figure 1, that is to say, the clutch boxes c¹ and f', remain in

page_text: gear with the clutches on the pinions cand f; but as soon as it is requisite to
stop any of the spindles and bobbins, the pins and h are pushed through the
bushes in the rails and h³, corresponding with the spindle and bobbin to be
stopped, until they enter into the grooves of the clutch boxes c' and f. The
double levers k and are then pushed by the attendant into the position
shewn by dotted lines in Figure 3, the effect of which draws the inclines
on the rails and 2 in the direction of the arrows in Figure 2, thereby
raising the rails 3 and h³, and with them the pins and ho, sufficiently high to
lift the clutch boxes c¹ and f¹ out of gear. By this means the spindle and
bobbin are stopped until the piecing or other object for which the stoppage
was required has been accomplished; the attendant then raises the trigger l'
thereby liberating the catch piece from the notch in the plate ; the spring k
acting on the short arm of the catch piece ³, then draws the double levers
and and the rails and into their original positions, the springs
and he draw down the rails and h³, and with them the clutch boxes
c and f', which again drop into gear, thereby giving motion to the spindle and
bobbin that had been stopped. When a roving breaks between the front
roller and the bobbin, it is requisite or desirable to break the roving between
the traverse rail and the back roller in order to prevent waste. By means of
the improvements above described, any single spindle and bobbin may be
stopped and again started without stopping the whole machine; consequently,
much time is economized, as it is now customary to stop the whole machine
when an end requires piecing, or for any other cause requiring the stoppage of
a single spindle. Although I have shewn the clutch boxes on the spindles,
they may be applied to the shafts d' and g¹.
Having thus described the nature of my Invention, and the manner of
performing the same, I wish it to be understood that I do not limit myself to
the precise details herein set forth; but what I do claim is, the improved
machinery shewn and described for stopping and starting any spindle or bobbin
of roving frames, or other machines of the like nature, independently of the
other parts of the machine.
In witness whereof, I, the said Robert Caunce, have hereunto set my
hand and seal, this Fourteenth day of February, in the year of our
Lord One thousand eight hundred and fifty-five.
ROBERT CAUNCE. (L.s.)
