PROVISIONAL SPECIFICATION left by the said Frederick Tolhausen
at the Office of the Commissioners of Patents, with his Petition, on the
13th July 1861.
I, FREDERICK TOLHAUSEN, Civil Engineer & Patent Agent, of 35, Boulevart
Bonne Nouvelle, Paris, in the Empire of France, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING
RIBBONS AND OTHER FABRICS," a communication from Georges Duplay, Loom
Maker, a person resident at No. 11, Rue Notre Dame, St. Etienne, in the
Empire of France, to be as follows:-
The object of this Invention is a batten so arranged that any number of
shuttles may be employed for weaving figured fabrics. For this purpose,
instead of using one picking apparatus or "marionnette" for each shuttle, I
have devised a batten constructed as follows:-The shuttles are mounted on
racked carriers and in multiple moveable sliding frames, by which means

page_text: they may be thrown in and out of gear with a series of driving pinions keyed
on parallel shafts; said parallel shafts are arranged in a vertical plane, and
"simultaneously set in alternate motion by means of an endless chain, which
derives its motion from a shaft and bevel gear, which is driven by another
endless chain, to which the operator imparts a reciprocating motion by means
of a sliding carriage provided with right and left hand clicks; said sliding
carriage is put in motion by the ordinary means, viz., crank and connecting
rod.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Tolhausen in the Great Seal Patent Office on the
13th January 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
TOLHAUSEN, Civil Engineer and Patent Agent, of 35, Boulevart Bonne Nou-
velle, Paris, in the Empire of France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of July, in the year of our Lord One
thousand eight hundred and sixty-one, in the
year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Frederick Tolhausen, Her special licence that I, the said Frederick Tolhausen,
my executors, administrators, and assigns, or such others as I, the said
Frederick Tolhausen, my 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 "IMPROVE-
MENTS IN LOOMS FOR WEAVING RIBBONS AND OTHER FABRICS," a communication
from Georges Duplay, Loom Maker, a person resident at No. 11, Rue Notre
Dame, St. Etienne, in the Empire of France, upon the condition (amongst
others) that I, the said Frederick Tolhausen, 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 Frederick Tolhausen, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-

page_text: statement:-

As stated in my Provisional Specification, the object of these improvements
is to afford the means for using in a practical manner a greater number of
shuttles than heretofore, and thus weave fabrics of greater variety and richness
of colors; and also to obtain the shuttle motion by a single "marionnette" or
shuttle driver, instead of using one marionet 'for each shuttle, which is a source
.of much trouble in fancy weaving. Thus by substituting one single marionet,
or rather a marionet carrier, an indefinite number of shuttles may be used
instead of eight, which hitherto was considered to be the highest number
practically applicable.
Fig. 1 of the annexed Sheet of Drawings shews the body of the lathe-to
which I apply the mechanism shewn at Fig. 2, which is the ascending and
descending part of the lathe.
The carrier A is capable of producing a vertical reciprocating motion, and
is provided right and left with tongues B, B', each of which may be inserted
in the chain C by means of a small elbow lever D, which is acted upon by a
band from the jacquard. When the left hand lever is raised, and the left
tongue inserted in the endless chain, the contrary effect takes place on the
right-hand side, and vice versâ. The carrier A is actuated by the usual con-
necting rod for marionets; hence it will be easily understood how the vertical
motion is produced by the chain C, so as to correspond with the motion of
the shuttles. Thus upon imparting an alternate motion to the chain C, this
motion is transmitted in the same ratio to the endless chain G, by means of
bevel gear E and pinions F, F, F', which work the shafts H and pinions K.
Thence the motion is transmitted to the shuttles, by bringing the ascending
part (Fig. 2) of the lathe into the position shewn in pink lines Fig. 1, the
ascending or descending motion of the lathe being regulated in such manner
by the guide pieces L, that the pinion K shall produce their reciprocating
rotary motion, between the empty or open spaces M of the shuttle carriers,
i.e., so as to gear into the rack N (Fig. 3), with which the corresponding
shuttle is provided. Any of the usual systems may be applied for effecting
the ascending motion; I would, however, use in preference to others the
contrivance shewn at Fig. 4. In this plan, the main shaft O of the loom is
made to raise or depress the lever Q by means of the tappets P, and a
reciprocating motion is obtained by the rod R, provided with a hook R¹ at
the upper end. The ascending part of the lathe is attached by a rod to the
left-hand end of the upper lever S of the loom; to the right-hand end of this
lever I attach a box containing as many tongues as there are shuttles, each of

page_text: which is actuated by the strings of the jacquard. The hooked rod R passes
freely through these tongues, which are perforated for that purpose, and thus
any one of the tongues being drawn by the jacquard, the hook of the rod is
prevented from passing, and made to enter a hole recess provided for that
purpose. Thus it will readily be understood that according to the tongue acted
upon by the jacquard, a greater or less motion is imparted to the lever S,
and the ascending part of the lathe raised more or less.
In witness whereof, I, the said Frederick Tolhausen, have hereunto sét
my hand and seal, this Ninth day of January, A.D. 1862.
