IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1875

page_text: LETTERS PATENT to Ferdinand Henry Ziffer, of the Firm of Ziffer
and Walker, of Boston Works, Manchester, in the County of
Lancaster, Engineers, for the Invention of "IMPROVEMENTS IN LOOMS
FOR WEAVING."
Sealed the 2nd November 1875, and dated the 10th May 1875.
PROVISIONAL SPECIFICATION left by the said Ferdinand Henry
Ziffer at the Office of the Commissioners of Patents, with his
Petition, on the 10th May 1875.
I, FERDINAND HENRY ZIFFER, of the Firm of Ziffer and Walker,
of Boston Works, Manchester, in the County of Lancaster, Engineers,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
LOOMS FOR WEAVING," to be as follows:-
This Invention is designed to more effectually stop the loom on the
shuttle not arriving in the shuttle box at each beat up of the sley, and
to more effectually stop the loom in the proper position when the loom
stops on the breakage of weft. In carrying out this Invention I employ
a brake in connection with a brake wheel, which is keyed on the crank

page_text: shaft of the loom, as in the case of the arrangement ordinarily known
as the Burnley brake. The upper part of the said brake is mounted
on a stud fixed to the frame side, the lower part being formed for
attachment to a brake bar. The said brake bar extends from the brake
to the frog on the loom side, and is fastened to the said frog, and
also to the brake. I form the said brake bar from sheet steel, and so
bend or curve it as to form a spring; but I prefer to make the spring
of an undulated or corrugated form, so as to give elasticity to the
aforesaid brake bar. On the protector striking the frog the said brake
bar draws the brake to the brake wheel, and the momentum of the sley
being imparted to the aforesaid spring brake bar through the frog causes
it to tighten the brake against the brake wheel, the brake bar forming
an elastic medium to receive the blow from the sley.
In place of the ordinary thrust bolt usually bolted to the stop rod or
spring handle I employ a bolt having a forked end resting on the horn
of the frog.
On the weft lever knocking off the loom through breakage of the
weft the forked bolt attached to the stop rod or spring handle pulls the
back brake to the brake wheel, and so stops the loom in position to
receive a new supply of weft.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Ferdinand Henry Ziffer in the Great Seal Patent
Office on the 10th November 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FERDINAND
HENRY ZIFFER, of the Firm of Ziffer and Walker, of Boston Works, 2
Manchester, in the County of Lancaster, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of May, in the year of our
Lord One thousand eight hundred and seventy-five, in the thirty-eighth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Ferdinand Henry Ziffer, Her special licence that
I, the said Ferdinand Henry Ziffer, my executors, administrators, and
assigns, or such others, as I, the said Ferdinand Henry Ziffer, my exe-
cutors, administrators, and assigns, should at any time agree with, and

page_text: 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
LOOMS FOR WEAVING," upon the condition (amongst others) that I, the said
Ferdinand Henry Ziffer, my executors or administrators, by an instru-
ment in writing under my, or their,. or one of their hands and seals,
should particularly describe and ascertain the nature of the said Inven-
tion, 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 Ferdinand Henry Ziffer, 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, reference being had to the Drawing
hereunto annexed, and to the letters and figures marked thereon (that is
to say)
:-
This Invention is designed to more effectually stop the loom on the
shuttle not arriving in the shuttle box at each beat up of the slay, and
to more effectually stop the loom in the proper position when the loom
stops on the breakage of weft. In carrying out this Invention I employ
a brake in connection with a brake wheel which is keyed on the crank
shaft of the loom, as in the case of the arrangement ordinarily known
as the Burnley brake. The upper part of the said brake is mounted on
a stud fixed to the frame side, the lower part being formed for attach-
ment to a brake; but the said brake bar extends from the brake to the
frog on the loom side, and is fastened to the said frog, and also to the
brake. I form the said brake bar from sheet steel, and so bend or curve
it as to form a spring; but I prefer to make the spring of an undulated
or corrugated form, so as to give elasticity to the aforesaid brake bar.
On the protector striking the frog the said brake bar draws the brake to
the brake wheel, and the momentum of the slay being imparted to the
aforesaid spring brake bar through the frog causes it to tighten the
brake against the brake wheel, the brake bar forming an elastic medium
to receive the blow from the slay.
In place of the ordinary thrust bolt usually bolted to the stop rod or

page_text: of frog.
On the weft lever knocking off the loom through breakage of the weft.
the forked bolt attached to the stop rod or spring handle pulls the back
brake to the brake wheel, and so stops the loom in position to receive
a new supply of weft.
Fig. 1 is a side elevation shewing so much of loom as is required to
describe my Invention; Fig. 2 is a plan of same.
the spring brake bar
A is the crank shaft, on which are keyed the brake fly wheels B, B,
and the fast and loose pulleys C, C. On the crank shaft A arc con-
nected the crank arms D, D, at one end, and on the opposite end by a
pin to slay swords E, E. The slay swords being made to swing on their
respective centres F in the usual way on front of slay sword is fit a stop
rod or protector bar G; on loom side is fit a frog H (or frogs H, H,)
having a shank or "horn" I cast on side, to which is fit a hook bolt J,
which is bolted to the spring handle K, the spring handle K being
bolted to loom side. The frog plate L is made with a recess to receive
M, and is bolted to frog plate L by bolt fastening
plate L to the frog H, and the opposite end of spring brake bar M is
connected to back brake N by means of a set screw O, the back brake N
working on a stud P bolted to loom side in the usual way. On the
shuttle failing to arrive in the box on the opposite end of loom the
protectors G come down on the frog or frogs H and force the said frog H
in the direction of the slay sword D, the spring brake bar M being
attached to the frog plate L on one end, and on the opposite end being
attached to back brake N the action of the frog H draws the back
brake N by means of the spring brake M to the brake wheel or wheels
B, B, and thereby stops the looms. The spring in the said brake
bar M to receive the concussion of the slay is formed by corrugating or
undulating a bar of sheet steel in place of the usual straight bar; this
said action of spring back brake bar M being utilised when the shuttle
fails to "box." On the weft or thread breaking, and the spring
handle K being removed from its notch to "knock off" the loom by the
action of the weft fork, the hook bolt J draws the frog H and through
the brake bar M (which is connected to frog H) and brake N to the
brake wheel or wheels B, B, thereby stopping the loom in proper
position to receive a new supply of weft, dispensing with ordinary

page_text: weights and levers and combining weft and back brake in one; this
arrangement may be used as a single or double brake, as required.
Having now described the nature of my Invention, and the manner in
which the same is applied to looms, I distinctly wish it to be understood
that I claim the application of a corrugated or undulated steel draw or
brake bar for stopping the loom on the "knocking off" of the loom.
In witness whereof, I, the said Ferdinand Henry Ziffer, have here-
unto set my hand and seal, the Ninth day of November, in
the year of our Lord One thousand eight hundred and seventy-
five
