IM- PROVEMENTS IN POWER LOOMS
Year: 1859

page_text: LETTERS PATENT to John James Sieber, of 5, Baring Street, New North
Road, London, in the County of Middlesex, for the Invention of "IM-
PROVEMENTS IN POWER LOOMS."-A communication from abroad by Henry
Honegger, of Thiengen. Grand Duchy of Baden.
COMPLETE SPECIFICATION filed by the said John James Sieber at the
Office of the Commissioners of Patents with his Petition and Declaration,
on the 6th September 1859, pursuant to the 9th Section of the Patent
Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENT SHALL COME, I, JOHN
JAMES SIEBER, of 5, Baring Street, New North Road, London, in the County
of Middlesex, send greeting.
WHEREAS I am in possession of an Invention which has been com-
unicated to me from abroad by Henry Honegger, of Thiengen, in the Grand
Duchy of Baden, for "IMPROVEMENTS IN POWER LOOMS," and have petitioned
Her Majesty to grant unto me, my executors, administrators, and assigns,
Her Royal Letters Patent for the same, and have made solemn declaration
that the same has been comunicated to me as aforsaid.
NOW KNOW YE, that I, the said John James Sieber, do hereby declare
that the following Complete Specification under my hand and seal fully
describes and ascertains the nature of the said Invention, and the manner in
which the same is to be performed (that is to say) :-
This Invention relates to a new arrangement applicable to the different

page_text: -
kinds of power looms by which the loom is worked at any desired speed, and
consists of a most simple and practicable contrivance which causes the shuttle
to stop and keep fast in the shuttle box on one side, whereby the same is
prevented from recoiling, and to release the same again therefrom befor the
stroke is being made, in order to give it a passage without any hindrance to
the shuttle box on the other side, where the same is stopped and again released
as befor.
In order that the Invention comunicated to me may be better understood
and more redealy carried into effect, I will now proceed to describe the same,
reference being had to the accompanying Sheet of Drawings, and to the letters
and figures marked thereon, the same parts being marked with the same
letters of reference with regard to Figs. 1, 2, & 3, and Figs. 4, 5, & 6,
respectively, of which Figs. 1, 2, & 3, show a power loom where the shuttle is
thrown by the stick (which passes through the bottom of the shuttle box)
without the use of a fly and strap. To let the shuttle pass from one shuttle
box into the other without any hindrance, and to keep it fast when it arrives
in it, a stop piece A is attached to the stop pinion. To this stop piece is a
strap attached at b, which passes accros the shuttle box, and at c downwards
towards the stick, to which it is attached at d. If-now, the shuttle arrives
into the shuttle box, it will push the stick outward at the top end a, and
tighten the strap, which causes the stop piece to press against the shuttle and
keep the same fast, so as not to let it recoil in any way, by which means the
power loom may be worked at any desired speed, and with much less power
than hitherto. To loosen the shuttle again befor the stroke is being made, a
point is attached to the framework of the loom, to support a movable
lever f, g. The stop pinion has a prolongation from i to k, which, by means
of a strap or string is connected with the lever from k to f. If, by means of
the excentric h, the lever is lifted at g, the other end of the same at will
move downwards, and being connected with the stop pinion by means of the
strap and prolongation i, k, to which the stop piece A is attached, it will pull
the part i, k, downwards, and loosen the shuttle till it again touches the stick
on the other side. The shuttle therefor passes from one side to the other
without
sany hindrance whatever, whereby every friction is prevented.
To another kind of power looms, as Figs. 4, 5, & 6, where the shuttle is
thrown by means of a fly and strap attached to the stick, a point c is attached
to the back of the shuttle box, on which is movable an angle a, b. This angle
is fixed so as to let the part a press against the stop piece d, e, (which latter
has the form or shape of a tongue.) The part 6 of the angle goes accros the
b
shuttle box, and at the end of it at b is a strap attached, which is fastened to

page_text: the end of the shuttle box at f. Now, as soon as the shuttle arrives into the
shuttle box, it pushes the fly outwards against the strap f, b, and causes the
same to become tight, by which means the end a of the angle is pressed
against the stop piece, which latter keeps the shuttle fast the moment it
arrives entirly into the shuttle box, so as not to let it recoil again. The
shuttle is made loose again befor the stroke is being made in the following
manner: A point is fixed to the frame of the loom, on which is movable a
lever m, g, put in motion by the excentric h. The stop pinion has a pro-
longation i, k, and a strap from h to k connects it with the lever. If now the
loom is put in motion, the excentric will lift the end g of the lever, and cause
the end m to move downwards, as well as the prolongation i, k, whereby the
shuttle is loosened again, and passes without any hindrance to the other shuttle
box till it touches the fly, where the same is kept fast and loosened again
as befor.
Having now described the nature of the said Invention, and the manner in
which the same is to be performed, I wish it to be understood that what I
claim as the Invention intended to be secured to me by the above in part
receited Letters Patent is, the peculiar shape of the shuttle stop piece, and the
manner in which the shuttle, when arriving into the shuttle box is stopped
and prevented from recoiling, and released again, as well as the whole
arrangement as herein-befor described, by which means the loom may be
worked at any desired speed, and with less power than hitherto.
In witness whereof, I, the said John James Sieber, have hereunto set
my hand and seal, this Sixth day of September, in the year of our
Lord One thousand eight hundred and fifty-nine.
TATTET
JOHN JAMES SIEBER. (L.B.)
