99,
Sealed the 17th January 1871, and dated the 11th August 1870.
PROVISIONAL SPECIFICATION left by the said Samuel Brooks and
John Standish at the Office of the Commissioners of Patents, with
their Petition, on the 11th August 1870.
We, SAMUEL BROOKS, of the Union Iron Works, West Gorton, near
Manchester, in the County of Lancaster, Machine Maker, and JOHN
STANDISH, of the same Place, Mechanic, do hereby declare the nature of
the said Invention for "CERTAIN IMPROVEMENTS IN MACHINERY FOR PREPARING
COTTON AND OTHER FIBROUS SUBSTANCES," to be as follows
:_
Our Invention is chiefly applicable to drawing frames and other
machines of the like description, and it consists in certain improvements
in the front and back'stop motions of such frames, whereby the machine

page_text: is stopped when a sliver fails between the cans and the back drawing
rollers, and between the front drawing rollers and the calender rollers.
Our improvements in the back stop motion consist in making the
balance spoons of a ✓ shape, so that they may be adapted to every
thickness of sliver; also in supporting the spoons on a knife edge and
making them with a projection which comes against the edge of the
covering plate, when they fall and are acted upon by the wings of the
vibrating shaft or other equivalent, or with a projection under the tail
end of the spoon which comes against the edge of a back plate when it
falls and is acted upon as before described.
Another part of our improved back stop motion consists in making
all the back guides separate, so that the distance between them can be
adjusted to distribute the slivers over the bosses of the drawing rollers,
also in making the rests against which the spoons fall with recesses to
hold the spoons when down.
Our improvements in the front stop motion consist in combining the
spoon or lever and the trumpet mouth together, the trumpet mouth being
placed over the fulcrum of the spoon or lever, also in placing two or
more of the said spoons or levers, or other spoons or levers, in diagonal
or other positions to convey the sliver or slivers to the calender rollers.
Our Invention may be modified by combining the guide or trumpet
mouth with the spoon of the back stop motion.
Our Invention is partly applicable to slubbing frames and other
machines of the same description.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Brooks and John Standish in the Great
Seal Patent Office on the 10th February 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, SAMUEL
BROOKS, of the Union Iron Works, West Gorton, near Manchester, in
the County of Lancaster, Machine Maker, and JOHN STANDISH, of the
same Place, Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of August in the year of
our Lord One thousand eight hundred and seventy, in the thirty-fourth

page_text: year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said Samuel Brooks and John Standish, Her special
licence that we, the said Samuel Brooks and John Standish, our
executors, administrators, and assigns, or such others as we, the said
Samuel Brooks and John Standish, 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
COTTON AND OTHER FIBROUS SUBSTANCES," upon the condition (amongst others)
that we, the said Samuel Brooks and John Standish, 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..
KNOW NOW YE, that we, the said Samuel Brooks and John Standish,
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 chiefly applicable to drawing frames, but it may be
applied to other machines of the like description, and it consists in certain
improvements in the front and back stop motions of such frames,
whereby the machine is stopped when a sliver fails between the cans
and the back drawing rollers, and between the front drawing rollers and
the calender rollers.
And in order that our Invention may be fully understood and readily
carried into operation, we will proceed to describe the accompanying Sheet
of Drawings, reference being had to the figures and letters marked
thereon.
Fig. 1 is a sectional elevation of part of a drawing frame to which our
improvements are applied, and Fig. 2 is a plan of the same; Figs. 3, 4,
and 5 are detached views of parts of our improvements.
a is the roller beam; b, the stands; c, c, the fluted rollers; d, d, the
top rollers; d, the calender rollers; e, the rail or plate in which the
guide studs e¹ are fixed; fis a plate placed rather below the plate e,

page_text: and g is the curved plate over which the slivers pass as they are drawn
out of the cans; h is the oscillating shaft, and i the oscillating rail of the
back stop motion, the parts above enumerated are made in the ordinary
manner, excepting that the front edge of the plate f is bevelled, the
object of which will be explained hereafter. To the lower edge of the
curved plate g are fixed the guides g', which are all made in separate
pieces, so that the distance between them may be adjusted to distribute
the slivers over the bosses of the drawing rollers. Between the ends of
the plates and g is the knife edge rail k, which extends the whole
length of the frame in order that the spoons 7 which fit upon it may be
placed in any position. The peculiar construction of the spoons is shewn
best in Figs. 2 and 3, the part through which the sliver passes is V-shaped
and rounded at the bottom, whereby the spoon is adapted to every size
of sliver, the bottom of the spoon is partly cut away in front to increase
the friction of the slivers on the spoons, and thereby to allow the same
spoons to be used for different thicknesses of sliver. When the slivers
are carried forward by the drawing rollers the spoons are held against
the rest f¹ fixed on the plate f, these rests are made with recesses
corresponding in shape to the bottom of the spoon, and the distance
between the recesses is a little greater than the largest part of the spoons,
to prevent them crowding together. The front angle of the spoon fitting
on the knife edge rail is made flat, so that it may bear against the
bevelled edge of the plate f, when the tail of the spoon has been pushed
forward by the oscillating rail i or other equivalent, as shewn in Fig. 4.
To the vibrating shaft h is fixed the lever h¹, the upper end of which
is provided with trunnions on which the forked end of the connecting
rod j fits, this rod passes as usual under the drawing rollers and it is
provided at the other end with two inclines which act on the tails of
the spoons m of the front stop motion when two such spoons are used,
as shewn in Fig. 2, but when only one spoon is used the end of the
red is made as usual.
Our improvements in the front stop motion consist in making the
spoon m, and the trumpet mouth n in one piece, or in combining them
together as shewn in Figs. 1 and 2, so that the trumpet mouth being
placed almost immediately over the knife edge or fulcrum on which it
vibrates may assist in balancing the spoon and render it more accurate
in its action. In a double drawing head, as shewn in Fig. 2, each being
supplied with three slivers as indicated by the dotted lines, the three
slivers from each boss are taken through one spoon m, and these spoons

page_text: are placed diagonally, so that the six slivers may be united in passing
between the calender rollers d', the object of using two spoons whether
of my improved description combined with the trumpet mouth, or of
the ordinary description is also to render their action more accurate.
The knife edges of the spoons mare cast with the curved plate o, which
is hinged to the bracket p as described in the Specification of Letters
Patent granted to the within named John Standish and John Gooden,
on the Twentieth day of August One thousand eight hundred and sixty-
two, Number 2331.
The mode of operation is as follows, and the Drawing represents the
parts in the positions they occupy when the slivers are all passing
through their respective guides and spoons from the cans to the calender
rollers, the tail ends of the spoons and mare held up, and the rail i and
the inclines on the connecting rod j are free to oscillate to and fro under
them. As soon as one or more of the slivers fails to pass through one of
the spoons 1, the preponderating weight of the tail end causes the spoon
to assume the position shewn in Fig. 4, the end of the tail then drops.
and comes in line with the oscillating rail i, which in moving towards
the knife edge rail k, presses the flat edge of the spoon against the
bevelled edge of the plate f, thereby preventing the advance of the rail i,
and causing the driving strap to be moved from the fast to the loose
pulley by the usual mechanism. The attendant then replaces the
missing sliver or slivers, and the spoon being again drawn forward, as
shewn in Fig. 1, allows the oscillating rail i to move to and fro under the
tail end of the spoons 1, as before.
In like manner when one or more
slivers fail between the front drawing rollers c and the calender rollers d¹
the tail end of the spoon m falls, and the incline on the end of the
connecting rod j comes against it, thereby binding the hook on the tail
end of the spoon against the bracket o¹ cast to the plate o, this stoppage
of the rod j throws the driving strap from the fast to the loose pulley in
the ordinary manner.
Fig. 5, represents a modification of our improvements in the back stop
motion. In this arrangement the tail end of the spoon 7 is made with a
projection, which when the sliver fails and the spoon falls back is caught
by the vibrating rail i and pressed against the rail g', which is fixed to
the under side of the plate g.
Our Invention is partly applicable to slubbing frames and other
machines of the same description.

page_text: Having thus stated the nature of our Invention and described the
manner of performing the same, we declare that we claim,-
First. Making the spoons of the back stop motion of a ✓ shape and
rounded at the bottom and leaving the bottom of the spoon partly open
to adapt them to slivers of different thicknesses, and to increase the
friction of slivers on the spoons.
Secondly. Causing the oscillating rail of the back stop motion to act
on the end of the tail of the spoon, when the spoon is supported on a
knife edge and binding the front plate of the spoon against the edge of a
plate or rail.
Thirdly. Making the knife edge rail for supporting the spoons of stop
motion of sufficient length to support the whole or any number of the
spoons whereby the spoons may be placed in any position.
.
Fourthly. The rests marked f¹ or any equivalent for supporting the
spoons.
Fifthly. Making the guides g' in separate pieces, whereby the slivers.
may be distributed at any distance apart.
Sixthly. Combining the spoon and trumpet mouth of the front stop
motion.
And, lastly, placing the spoons of the front stop motion in diagonal a
positions to unite the slivers at the calender rollers.
In witness whereof, we, the said Samuel Brooks and John Standish,
have hereto set our hands and seals, this Seventh day of February
One thousand eight hundred and seventy-one.
