PROVISIONAL SPECIFICATION.
Improvements in or relating to Rotary Shuttles for Looms and
Mechanism for Actuating the same.
A communication from abroad by JOHANN HERMANN MAHR, of Flensburg, in the
Empire of Germany.
I WILLIAM PHILLIPS. THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster, and 323, High Holborn, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is the arrangement of a shuttle, having a rotary motion
for the purpose of conducting the woof or weft from one side only into the warp,
whilst the ordinary shuttles, which have a see-saw motion are conducting the woof
from both sides into the warp.
For this purpose the shuttle guides, in which the under part of the shuttle engages
and is secured, are constructed and arranged in the form of a circle, and resembling
the letter I in cross section.
The motion of the shuttle is effected by toothed segments fixed on the guides
(on the outside or on the inside) into which engage toothed driving wheels.
The apparatus may be arranged with three shuttles, or a greater or less number
may be employed.
These apparatus are especially applicable for ribbon weaving to make the laces or
edgings, which hitherto have been generally executed by hand.
Dated this 15th day of April 1889.

COMPLETE SPECIFICATION.
Improvements in or relating to Rotary Shuttles for Looms and
Mechanism for Actuating the same.
A communication from abroad by JOHANN HERMANN MAHR, of Flensburg, in the
Empire of Germany, Gentleman.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool and 6, Bank Street, Manchester, both in
the County of Lancaster, and 323, High Holborn in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
The object of this invention is the arrangement of one or more shuttles having a
rotatory motion for the purpose of conducting the woof or weft from one side only
into the warp, whilst the ordinary shuttles, which have a reciprocating motion, are
conducting the woof from both sides into the warp.
In the drawings:
Figure 1 is an elevation of an apparatus constructed and arranged in accordance
with this invention.
Figure 2 is a section through the line of Figure 1.
Figures 3 and 4 are similar views of a modified construction.
The shuttle guides a, in which the under part of each of the rotating shuttles
engages and is secured. are constructed and arranged in the form of a circle, and

page_text: The motion of the shuttle is effected by circular toothed racks c fixed on the guides a
(on the outside, as shown in Figures 1 and 2, or on the inside, as in Figures 3 and 4)
into which engage toothed driving wheels e e.
These driving wheels e e are themselves driven by means of other spur wheels.
In Figure 3 they are shown as driven by a single central wheel 9, whilst in
Figure 1 the motion is communicated from one wheel e to another by intermediate
wheels one of which is actuated by a pinion i keyed or otherwise fixed on a
crank shaft.
°
Another gear wheel K may be used to transmit the motion from wheel i to a
second similar apparatus, and in this way two or more may be driven from one
crank shaft.
The apparatus may be arranged with three shuttles, or a greater or less number
may be employed.
h is the groove in which the ordinary shuttle is conducted.
The guide and rack a are formed with a recess B which allows of the shed being
formed as described below. A hole A is formed in the supporting plate of the apparatus
through which the warp threads are led. The warp beam is at one side of said plate
and the cloth beam is at the other.
The mode of action is as follows:-
The warp threads C normally lie preferably rather below (or above) the periphery
of the rack and guides a. When the apparatus is in the position shown in the
drawings the shed is formed by raising a certain number C₁ of the warp threads and
depressing the remainder C³. The number and order of the threads raised will of
course depend upon the pattern desired.
The series of rotating shuttles is now passed through by means of the goar
wheels, actuating the rack, and the apparatus again assumes the position shown.
The reciprocating shuttle or shuttles may also be passed if desired, or the shed
may first be reformed and then the reciprocating shuttle passed.
It must be understood that the above mode of using the apparatus is merely given
as an example.
These apparatus are especially applicable for ribbon weaving to make the laces or
edgings, which hitherto have been generally executed by hand.
The weft passing over the top of the ribbon forms a series of loops each reaching
from edge to edge and these are afterwards cut & their two halves go to form the
laces or edgings of the ribbon.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
The arrangement of one or more shuttles in a circular guide, which shuttles are
adapted to be driven in one direction by wheels arranged either within or without the
said guide, substantially as and for the purposes set forth.
