North Road, London, in the County of Middlesex, for the Invention
of "IMPROVEMENTS IN POWER LOOMS."-A communication from Henry
T
Sealed the 1st April 1858, and dated the 19th October 1857.
PROVISIONAL SPECIFICATION left by the said John James Sieber at
the Office of the Commissioners of Patents, with his Petition, on the
19th October 1857.
I, JOHN JAMES SIEBER, of 5, Baring Street, New North Road, London, in
the County of Middlesex, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN POWER LOOMS," (a communication from Henry Honegger,
of Thiengen, in the Grand Duchy of Baden,) to be as follows:-
This Invention relates to a new arrangement to cause the power loom to
make 200 and more strokes in one minute, and consists in a most practicable
and simple contrivance for stopping the shuttle in the shuttle box, which
stoppage, however, is taken off before the stroke is being made; and in the
use of a break for the purpose of stopping the loom without any shaking.
The front part or the small board in front of the shuttle box is moveable on
a pinion, which is fastened to an angle; to the hind part or small board of
the shuttle box is fixed a strong wooden spring, which by means of a screw
is connected with the small front board of the shuttle box, thus causing the
atter to secure the shuttle. The shuttle on arriving into the shuttle box is
hus, through the small front board, made fast; for loosening it again before
he stroke is being made an angle lever is attached to the outer end of the
mall front board of the shuttle box; this angle lever is in connection with
nother lever, which is acted upon by an excentric, and when pressed down

page_text: causes the small front board to move at the outer end inwards, and at the
inner end outwards, whereby the shuttle is being released. The outer end of
the small front board, as soon as the shuttle has arrived in the shuttle box,
moves inwards, and pushes thereby an angle lever attached to the stop-rod by
means of a screw backwards. By this movement the stop pinion is forced
upwards, and all communication with the stop rod ceases. When, however,
the shuttle is not being in the shuttle box, the stop pinion will act upon the
stop rod, which, by means of a screw, is in connection with a break. This
break operates upon the fly wheel, and thus prevents any shaking of the loom
when being stopped.
These improvements consist also in an improved témple, which is put in
motion by the machine. A vertical lever moveable on a pin is secured to the
framework of the machine. The upper end of this lever is connected with
the temple, which has the form of a pair of self-acting open tongs. At the
end of the upper arm of these tongs is attached a strap or band, which
passes through the lower arm, and thence over a guide pulley, down to a
horizontal lever, connecting both together. This lever is made fast at the
hind part of the loom, and is furnished with a roll, acted upon by an excentric
put in motion by machinery. At the lower end of the vertical lever upon
which the temple rests is attached a spiral spring, secured to the inner side
of the breast beam. The mouth of the tongs is bent forward as near as
If
possible to the reed, so as to get hold of the cloth close to the warp.
now, by means of the excentric, the horizontal lever is pressed down, the strap
or band will draw both arms of the temple or tongs together, which latter
keeps the cloth fast, at the same time distending it; the vertical lever attached
to the temple and the spiral spring will both also be acted upon. By
depressing the horizontal lever, the spiral spring will turn back in its norma
position, by which means the vertical lever is moved, and with it the temple
or tongs when the latter are open again, thereby releasing the cloth. Ther
are two temples acting together on both sides of the cloth. The whol
apparatus is secured to the breast beam.

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John James Sieber in the Great Seal Patent. Office
the 12th April 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN JAMES 35
SIEBER, of 5, Baring Street, New North Road, London, in the County of
Middlesex, send greeting.

my executors, administrators, and assigns, or such others as I, the
said John James Sieber, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there- .
after 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 "IMPROVE-
MENTS IN POWER LOOMS," a communication from Henry Honegger, of Thiengen, :
in the Grand Duchy of Baden, upon the condition (amongst others) that I, the
said John James Sieber, my executors or administrators, by an instrument in
writing under my, or their, or one of 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.
NOW KNOW YE, that I, the said John James Sieber, do hereby declare
the nature of the 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) :-
This Invention relates to a new arrangement to cause the power loom to
make two hundred and more strokes in one minute, and consists in a most
practicable and simple contrivance for stopping the shuttle in the shuttle box,
which stoppage, however, is taken off befor the stroke is being made; and
in the use of a break, for the purpose of stopping the loom without any
shaking.
In order that the Invention communicated to me may be better understood,
and more readily carried into effect, I will now proceed to describe the same,
referrence 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 referrence with regard to Figures 1, 2, & 3, and Figures 4,
5, & 6, respectively.
Fig. 1 is a top view of a power loom, with the improved shuttle box and
break; Fig. 2 is a side view of the same; and Fig. 3 shews the batten. The
front part or small front board a, b, of the shuttle box, see Figs. 1, 2, & 3, is
moveable an a pinion c, which is fastened to an angle d, c.
To the hind part

page_text: or sinall board of the shuttle box is fixed a strong wooden or iron spring f, g,
which, by means of a screw, is connected with the small front board at its
outer end at b, thus causing the latter to secure the shuttle. The spring f, g,
see Figs. 1 & 2, will cause the front board a, b, to press against the shuttle,
to keep it fast as soon as it arrives into the shuttle box. For loosening it
again befor the stroke is being made, an angle lever is attached to the small
front board a, b, at its inner end at a. This angle lever is in connection with
another lever attached to the hind part of the loom, and which is acted upon
by an excentric. When pressed down it will cause the small front board a, b,
to move at the one end at a inwards, and at the other end at 6 outwards,
whereby the shuttle is being released. In order for loosening the shuttle
befor the stroke is being made, the horizontal lever may also be dispensed
with, and carried out in the following manner :-The front board a, b, as shown
in Figs. 1, 2, & 3, has a prolongation from a to h. At h is a screw knob in
connection with a screw h, i, see Figs. 1, 2, & 3, which latter passes through
the lower part of the batten to an arm i, k, Figs. 2 & 3, which is fastened to
the stop rod, see Fig. 3. To the stop rod is attached another arm l, m, n,
Figs. 2 & 3, whose lower part m, n, is moveable an a pinion, and made to be
pushed in a backward direction. As soon as the batten is thrown backward
the arm l, m, n, Figs. 2 & 3, will touch the angle lever p, o, attached to the
frame, which causes the small front board a, b, to move outward at b, by
means of the arm and screw k, i, h, and release the shuttle; but at a it will
move inwards, just to let pass the shuttle, giving to the same a quite straight
direction, thus preventing it [from flying out. On the batten being thrown
inwards, the part m, n, of the arm l, m, n, will strip over the angle p, o,
Figs. 2 & 3, and thus not move the stop rod. If the shuttle arrives into the
shuttle box, the front board a, b, will move inwards at a, and outward at b,
whereby, by means of the screw and arm h, i, k, the stop pinion q is lifted,
and prevents thus a push to the stop piece r; but the shuttle not being in the
shuttle box, the stop pinion q will touch the band guide and stop piece z,
which latter, being connected by means of a screw, s, t, see Figs. 1 & 2, with
a break u, will cause the same to act upon the fly wheel, and thus prevents a
shake to the loom then being stopped.
And those improvements consist also in an improved temple, which is
attached to the breast beam, and put in motion by the machine. Figs. 4
& 5 shew the full size of the improved temple, which has the form or shape
of a pair of tongs; Fig. 6 is a side view of the power loom, with the temple
attached to it. The temple is attached at a to the upper end of a vertical
lever b, which latter rests and is moveable an a pin c, attached to the breast

page_text: beam. At the end of the upper part of the tong at d is attached a strap
or band, which passes through the lower part of the tong over the pulley e, and
from there over the guide pulley f, and is attached at 7 to a horizontal lever g,
connecting both together. To the lower end of the vertical lever b is, at h,
attached a spiral spring, which at its other end, at i, is attached to the inner
side of the breast beam, for the purpose of bringing the lever b, with the tong
at its top, to the normal position as soon as the lever g is released. The
lever g is attached to the hind part of the loom, see Fig. 6, (or it may be
attached to the breast beam, and acted upon by a pulley attached to the
batten,) and is pressed down at the pulley m, by means of the excentric n,
put in motion by machinery. The mouth or opening k of the tong is bent
towards the reed as near as possible, as shewn in Fig. 5, so as to get hold of
the cloth close to the warp. If now, by means of the excentric n, the
horizontal lever g is pressed down, the strap or band will draw both arms of
the temple or tong together, and outwards, thus keeping the cloth fast, and
distending it; and as there is a similar arrangement attached to the other
side of the loom, and acting in a similar manner, and at the same time, the
cloth will allways be regularly extended. If the excentric n release the
lever 9, the spiral spring will cause the temple to move to its normal position,
and being opened by means of the self-acting spring p, see Fig. 4, the cloth
is again released.
Having now described the nature of the said Invention, and the means of
performing the same, I wish to be understood that what I claim as the
Invention secured to me by the above in part recited Letters Patent, is,―
Firstly, the peculiar arrangement of the shuttle box for stopping the
shuttle and releasing it again, as well as the break, in which manner it is
applied to the power loom for stopping the same, as herein-befor described.
And, secondly, the peculiar form or shape of the temple, and the manner in
which it is applied to the loom, as herein-before described.
In witness whereof, I, the said John James Sieber, have hereunto set
my hand and seal, this Twelfth day of April, in the year of our Lord
One thousand eight hundred and fifty-eight.
JOHN JAMES SIEBER. (L.S.)
