PROVISIONAL SPECIFICATION left by the said Frederick Tolhausen
at the Office of the Commissioners of Patents, with his Petition, on
the 3rd November 1865.
I, FREDERICK TOLHAUSEN, of 149, Boulevart Magenta, Paris, Patent
Agent, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN SHUTTLE MOTION FOR LOOMS," a communication to me from Julius Schot-
tenfels, Manufacturer, a person resident in the City of New York, United
States of America, to be as follows:-
This Invention relates to certain improvements in the shuttle motion of
looms for narrow goods, such as ribbons, suspenders, or braces, and so
forth, in which the requisite motion is imparted to the shuttles generally
by a reciprocating toothed rack and a series of cog wheels arranged on
opposite sides of the gap, and in looms with two or more shuttles one above
the other. A vertically adjustable rack and pinion for each shuttle, or other
complicated mechanisms, are employed to impart to the shuttles the desired
motion, and the loom is rendered expensive and liable to get out of order.
These difficulties are obviated by this present Invention, which consists in

page_text: the employment or use of a reciprocating carrier in combination with the
toothed rack and cog wheels or other equivalent mechanism, and with a
series of shuttles mounted one above the other in a vertically adjustable
frame, and provided with guide grooves to receive suitable dogs which
project from the carrier in such a manner that by raising or lowering the
shuttle frame each of the shuttles in the tier can be thrown in gear with
one and the same carrier, and the desired motion is imparted to it without
requiring teeth in the shuttle itself, or without requiring a separate carrier
and separate racks and pinions for each shuttle, and with a mechanism
The
which is simple, durable, and not liable to get out of order.
mechanism last mentioned consists chiefly in arranging the shuttles in a
frame, which is vertically adjustable on dove-tailed strips secured to the
breast of the batten, and the several shuttles are arranged in different
shuttle races. These races are separated from each other by partitions,
which are held in place by vertical bars. Each of the shuttles is provided
on its rear surface with one or more vertical grooves, and if the shuttles
are driven clear to either end of the shuttle races the groove or grooves in
one shuttle register with those in the other shuttles and also with grooves
in the bottom rail of the frame. The carrier herein-before mentioned
travels in a suitable guideway in the batten, and which is provided with cogs
in its upper edge to gear into cog wheels that have their bearings on pins
secured in the batten, and to which a revolving motion is imparted first in
one and then in the opposite direction by the toothed rack herein-before
mentioned. This rack slides in the top edge of the batten, and is operated
by cords extending from its ends in opposite directions and secured to
pickers. The carrier aforesaid is provided on its inner side with one or
more studs or dogs which fit into the aforesaid grooves of the shuttles and

by the said Frederick Tolhausen in the Great Seal Patent Office 3
on the 27th April 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
TOLHAUSEN, of 149, Boulevart Magenta, Paris, Patent Agent, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters 3
Patent, bearing date the Third day of November, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-eighth year

page_text: 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, adminis-
trators, 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 "IMPROVEMENTS IN SHUTTLE MOTION FOR LOOMS,'
a communication to me from Julius Schottenfels, Manufacturer, a person
resident in the City of New York, United States of America, 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 performed, to be particularly described and ascertained in and by the
following statement :-
This Invention relates to certain improvements in the shuttle motion of
looms for narrow goods, such as ribbons, suspenders, and so forth, in which
the requisite motion is imparted to the shuttles generally by a reciprocating
toothed rack and a series of cog wheels arranged on opposite sides of the
gap, and in looms with two or more shuttles one above the other. A
.vertically adjustable rack and pinion for each shuttle, or other complicated
mechanisms, are employed to impart to the shuttles the desired motion, and
the loom is rendered expensive and liable to get out of order. These
difficulties are obviated by this present Invention, which consists in the
employment or use of a reciprocating carrier in combination with the
toothed rack and cog wheels or other equivalent mechanism, and with a
series of shuttles mounted one above the other in a vertically adjustable
frame, and provided with guide grooves to receive suitable dogs which
project from the carrier in such a manner that by raising or lowering the
shuttle frame each of the shuttles in the tier can be thrown in gear with
one and the same carrier, and the desired motion is imparted to it without
requiring teeth in the shuttle itself, or without requiring a separate carrier

page_text: and separate racks and pinions for each shuttle, and with a mechanism
which is simple, durable, and not liable to get out of order.
This Invention is illustrated in the accompanying Drawing, in which
Fig. represents a front elevation when the shuttle frame is raised and.a
portion of the batten is cut away to expose the working parts of the motion;
Fig. 2 is a transverse vertical section of the same taken in the plane indi-
cated by the line x, x, Fig. 1; Fig. 3 is a horizontal section of the same,
the plan of section being indicated by the line y, y, Fig. 1. Similar letters
of reference indicate corresponding parts.
A represents a portion of a batten or lay provided with a series of gaps a
through which the warp threads pass, and in which the shed is made to
let the shuttles pass. The shuttles B are arranged in a frame C, which is
vertically adjustable on dovetailed strips b, secured to the breast of the
batten, and the several shuttles are arranged in different shuttle races c,
that is to say, where four shuttles are used one above the other the frame
C is provided with four shuttle races, and it is obvious that the number of
shuttles and shuttle races can be increased to any desired extent. The
shuttle races are separated from each other by partitions d, which are held
in place by vertical bars e, and in practice the body of these bars and of
the partitions will be reduced as much as possible in order to obtain the
largest possible amount of light in weaving. Each of the shuttles is pro-
vided on its rear surface with one or more vertical grooves f, and if the
shuttles are driven clear to either end of the shuttle races the groove or
grooves in one shuttle register with those in the other shuttles and also
with grooves g in the bottom rail of the frame. C, D, is a carrier which
travels in a suitable guideway h in the batten or lay, and which is provided
with cogs in its upper edge to gear into cog wheels i that have their
bearings on pins secured in the batten, and to which a revolving motion is
imparted first in one and then in the opposite direction by the toothed rack
E. This rack slides in the top edge of the batten, and is operated by
cords extending from its ends in opposite directions, and secured to pickers
which are constructed in the usual manner. The carrier D is provided on
its inner side with two (more or less) studs or dogs j, which fit into the
grooves of the shuttles B and frame C, and by raising or lowering said
frame either of the shuttles can be thrown in gear with the dogs j and
made to pass through the shed. It is obvious that instead of securing the
dogs to the carrier said carrier might be provided with grooves and the
dogs attached to the shuttles, and in this case suitable grooves would have
to be made in the body of the batten to admit the dogs; the effect of

page_text: this arrangement would be precisely the same as that above described, and
I consider it a mechanical equivalent of my Invention. Suitable friction
springs m, secured in the shuttle races in the outer surface of the rising and
falling frame C, serve to retain the shuttles and to prevent them from
dropping into the shed spontaneously at such times when they are not
required. By this arrangement one toothed rack and one set of gear
wheels is sufficient to impart motion to all the shuttles, and the difficult
operation of adjusting the picker cords of the several shuttles is greatly
simplified, since only one pair of cords have to be kept in order, and if
these cords are of the proper length all the shuttles will work correct,
whereas in looms of the ordinary construction a separate pair of cords is
required for each shuttle, and it is exceedingly difficult to adjust all those
cords and keep them at the proper length.
It must be remarked that in a batten constructed according to this
Invention other means for propelling the shuttles might be substituted for
the rack and pinions.
CLAIM.
1. The carrier D, which travels in suitable guideways in the batten of
a loom when the same is used in combination with a rising and falling
shuttle frame C, carrying two or more shuttles one above the other, and
arranged to move up and down independent of the batten and carrier,
substantially as and for the purpose set forth.
2. Imparting motion to two or more series of shuttles one above the
other by one and the same rack, and by one pair of pinions to each
opening, substantially as and for the purpose described.
3°. The friction springs m in combination with the rising and falling
frame C, carrying two or more shuttles one above the other, and with the
carrier D and batten A constructed and operating substantially as and for
the purpose described.
In witness whereof, I, the said Frederick Tollausen, have hereunto set
my hand and seal, the Twenty-fourth day of April, in the year of
our Lord One thousand eight hundred and sixty-six.
