Year: 1871

page_text: LETTERS PATENT to Peter Brimelow, of Accrington, in the County
of Lancaster, for the Invention of "IMPROVEMENTS APPLICABLE TO
WARPING OR BEAMING MECHANISM."
Sealed the 14th June 1872, and dated the 18th December 1871.
PROVISIONAL SPECIFICATION left by the said Peter Brimelow at the
Office of the Commissioners of Patents, with his Petition, on the
18th December 1871.
I, PETER BRIMELOW, of Accrington, in the County of Lancaster,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
APPLICABLE TO WARPING OR BEAMING MECHANISM," to be as follows:-
This Invention has reference mainly to an improved self-acting stop
motion for a warping or beaming machine, such stop motion being com-
posed of three reeds, two at the top and bottom, fastened together at a
convenient distance to allow the third reed to oscillate between them.
It can be oscillated either by an eccentric or suitable cams. It has an
advantage over the present oscillating bars, as it will knock off at the
coming or receding side of the eccentric, thereby saving one-half of the

page_text: time. The two reeds that are connected together are stationary and in
contact with the knocking-off lever, so that when the pin drops it passes
-between-the-reeds, and the oscillating reed comes in contact with the
pin and pushes the stationary reeds forward, by which action the lever
is pushed from its resting-place, thereby stopping the machine.
My Invention comprises also a cast-iron strap and a loose boss. This
strap is square on one side, and the other side is shaped like a wedge, so
that when the treadle is pressed down by the foot the full side of the
wedge presses a loose. boss against the friction pulley. By this 'action
the machine is set in motion.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Peter Brimelow in the Great Seal Patent Office on
the 18th June 1872.

NOW KNOW YE, that I, the said Peter Brimelow, 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:-
This Invention has reference mainly to an improved self-acting stop
motion for a warping or beaming machine, such stop motion being
composed of three reeds, two the top and bottom, fastened together
at a convenient distance to allow the third reed to oscillate between
them. It can be oscillated either by an eccentric or suitable cams, it
has an advantage over the present oscillating bars, as it will knock off
at the coming or receding side of the eccentric, thereby saving one-half
of the time. The two reeds that are connected together are stationary
and in contact with the knocking-off lever, so that when the pin drops
it passes between the reeds, and the oscillating reed comes in contact
with the pin and pushes the stationary reeds forward, by which
action the lever is pushed from its resting place; thereby stopping the
machine.
My Invention comprises also a cast-iron strap and loose boss. This
strap is square on one side, and the other side is shaped like a wedge, so
that when the treadle is pressed down by the foot the full side of the
wedge presses a loose boss against the friction pulley. By this action
the machine is set in motion.

page_text: machine; Figs. 4, 5, 6, and 7, parts applied to the machine; Nos. 2 and 5
beneath Fig. 4 are top views of the stop motion; they are formed like
_grates or reeds, the ribs being diagonal or straight, as shown at A and B.
Nos. 1, 3, 4, 6, 7, 8, beneath Fig. 4, show different forms of ribs and front
views of the grates, the ribs being either triangular, round, oval, diamond,
or pear-shaped. To produce a stop motion I take two of these grates
and place them as shown in Nos. 1, 3, and 8, or three, as shown at
4, 6, and 7, beneath Fig. 4. When three are used the top and bottom
are fastened together while the middle grate traverses to and fro. But
two are preferable on account of simplicity and-economy. These grates
are supported by a rail on which is cast four or more bearings, as shown
at'A; A, A, A, in Fig. 3; this rail goes across the machine, and is bolted
to the sides. The top grate remains still and in contact with the
knocking off lever, as shown in Fig: 3 at B or in Fig. 2 at A, while the
bottom grate traverses to and fro from side to side of the machine,
worked by an eccentric or suitable cam, as shown at C in Fig. 3, so
when an end breaks or is absent the pin falls between the ribs of the
top grate and projects a little below, so that the ribs of the bottom grate
comes in contact with the pin and moves the top grate with it. By this
motion the lever B in Fig. 2 is pushed out of its detent C by the V
bracket, which is fastened to the top grate (top view shown in Nos. 2:
and 5 at B, C, beneath Fig. 4), thus causing the stoppage of the machine;
the top grate being brought back to its place. by the motion of the
bottom grate when the machine is re-started.
By this arrangement I arrive at a direct stop motion, which reduces
the time of stopping the machine to a minimum, besides dispensing with
all complicated mechanism, and making the machine simple, durable,
and easy to understand. The warpers have also the advantage of
increasing their number of ends, as the widths of the grates enables
them to increase the number of rows of pins. Nos. 2, 4, 5, 6, 7, 8, 9, 16,
17, 18, 19, and 20, in Fig. 5, are front and side views of the pins used,
In
No. 16 showing the front view of the pins 17, 18, 19, and 20.
Nos. 2, 4, 6, 8, 16, 17, 18, 19, and 20, the pins are suspended by the
warp threads at A. In Nos. 5, 7, and 9, they are suspended by the warp
threads at B. Nos. 1, 3, 10, and 15, are front and side views of eyes
used, No. 3 being front and side views of an eye which is slided on at
the end of the staves or strips, and the pin is then passed through it, as
shown-in-No. 13. -Nos. 1, 10, and 15, are front and side views of spring
which can be placed on any part of the staves or strips. The
eyes

page_text: swells at C in Nos. 4, 5, 6, 7, 8, 9, 17, 18, 19, and 20, are pressed in when
they are passed through the eye, but open out again, as shown in the
Drawings, after they have passed the swell. These swells prevent the
pins from jumping out of their places, and so prevent bad work; the
eyes also steady the pins and prevent them from travelling with the
' warp threads. No. 2 is a pin placed in the eye before the eye is placed
on the stave or strip. The ring at B is to prevent it from jumping out of
its place. No. 11 is a front and side view of a double pin or two distinct
pins connected by the bridge marked A, A; this double pin spans the
top of the strip, as shown at No. 12, the hook C coming in contact with
the strip at A, as shown in the Drawing. This hook is to prevent the
pins from jumping out of their places.. This double or two distinct pins
connected by a bridge is well adapted for slack ends and fluke, as the
warp threads support the pins at B. The warp threads can be allowed
to work in close proximity with the tops of the strips, thereby con-
tinually clearing the fluke or floss away as it accumulates. Nos. 5, 7,
and 9 are pins that possess the same property. The eyes and pins men-
tioned are made out of round or half round wire or out of flat metal.
No. 14 is the end view of a stave of wood with a glass rod on the top, as
shown at A; this glass rod protects the stave from the friction of the
warp threads. Fig. 6 is a top view of a double hook and three staves or
strips. The letters D, D, D, represent the staves or strips; A is a pin
that passes through them; B, B, are two hooks that keep them asunder;
F, F, the hooks; C, the nut by which they are screwed tight (G, part
passed through the side of the machine). All three are drawn up tight
by the nut E. The other end of the staves are secured in the same way
as shown in the Drawing. Fig. 8 is a front view of the hook. In the
place of the double hooks I also use cast-iron bracket with a L slot cast
through them, the front view of which is shown at D, D, in Fig. 3;
these are secured to the sides by screws or bolts as shown at E, E, in
Fig. 3. After these brackets have been secured to the sides the staves
or strips are then slidden into their places, as shown at F, F, in Fig. 3,
and all drawn up tight by the screws or bolts E, E. These are preferable
to the hooks, for in case any fluke should gather between them they can
be slidden out of their places, and the fluke or floss cleared away without
going to the trouble of unthreading all their pins. The end view of
these brackets is shown at A, A, in Fig. 1. L, L, in Fig. 3 are friction
plates fastened to the drum shaft M, M; K, K, are friction pulleys
which run loose on the drum shaft G, G, the means by which the friction

page_text: is applied to start the machine. Their front view is formed like a wedge,
and they are secured to the treadle levers by the pins H, H. I, I, I, I,
are loose bosses with flats at each side. This part fits in the cast-iron
straps G, G, the straps preventing the bosses from revolving with the
drum shaft so that the inclines of the bosses are always in the same
position as the inclines of the wedges. When the machine is started the
warpers press their foot on the treadle N, and so bring the thick end of
the wedge on the right hand in contact with the bosses I; I, one boss
being pressed against the step. The other boss presses the friction
pulley K against the friction plate L, and starts the machine, the
treadle N being held down by the lever O falling in its detent at P, the
said lever being secured to the cast-iron strap by a pin, as shown at K
in Fig. 2. When a pin falls through an end breaking the lever O in
Fig. 3 is pushed out of its detent P, and the treadle N is then raised by
the weights as shown in Fig. 1 at G and in Fig. 2 at I, the treadle levers
being secured to a shaft which goes across the machine (end views of
which are shown at F in Fig. 1 and H in Fig. 2). When the treadle
rises it brings the thick end of wedge on the left-hand side of the
machine in Fig. 3 in contact with the bosses, pressing one against the
step and the other against the friction pulley, which runs in a reverse
direction to the one on the right hand, by which action the friction
pulley is brought in contact with the friction plate, and the machine
stopped almost instantly.
T
To prevent the machine re-starting in an opposite direction I secure
a spring to the side thereof, a front view being shown in Fig. 7.
A represents the side to which the spring is bolted; B shows the end
view of the treadle lever in contact with the spring; H in Fig. 1
shows the end view of the spring, so that when the treadle levers rise
-the-one-on-the-left-hand-comes in-contact-with the spring-and-over-
comes it for a time, so that the friction pulley comes in contact with the
friction plate and stops the machine. After the machine is stopped the
spring raises the treadle levers and removes the friction from the
reversing pulley; the machine is then free from all danger of re-starting
of itself. C-in-Fig-1 and F-in Fig. 2 are end views of the cast-iron
straps; D in Fig. 1 and E in Fig. 2 are end views of the bosses; B in
Fig. 1 and D in Fig. 2 are end views of the drum shaft; E in Fig. 1 and
Gin Fig. 2, the pins by which the cast-iron straps are secured to the
treadle levers.

page_text: raving now particularly described and ascertained the nature and
object of my said Invention, and in what manner the same is to be
performed or carried out in practice, I hereby declare that I claim
the Invention of "Improvements applicable to Warping or Beaming
Mechanism," it being understood that the following are special and
important features :-
The grates with their various formed ribs, likewise the various formed
pins, together with the various formed eyes through which the pins
pass.
Also the use of the double pin or two distinct pins connected or
spanned by a bridge.
Also the use of strips of metal or staves of wood, either with or
without glass rods on the top, which protect the staves from the friction
of the warp threads, together with the cast-iron brackets with a L slot
cast in them, and the double hooks by which the strips or staves are
secured to the machine.
Also the use of the cast-iron straps formed like a wedge, together with
the loose bosses that fit therein, for applying friction to start or reverse
the machine.
Also the use of the spring which is overcome for a time by the
treadle levers, so that the reversing pulley can nip the friction
plate and stop the machine, so that after the machine is stopped
the spring shall raise the treadle levers and remove the friction of
the reversing pulley, and so free the machine from all danger of
re-starting.
In witness whereof, I, the said Peter Brimelow, have hereunto set
my hand and seal, this Thirteenth day of June, in the year of our
Lord One thousand eight hundred and careantre tree
