PROVISIONAL SPECIFICATION.
Improvements in Small-ware Looms.
I, STEPHEN BARNWELL, of Cannon Street, Manchester, in the County of
Lancaster, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
.
This invention relates to that class of loom in which ribbons, tapes, and similar
narrow articles are woven and known as small-ware looms, and is designed with
the object of providing means whereby two, three or more fabrics superimposed or
placed one above the other will be woven at the same time the shuttles working
simultaneously so that a greater amount of work may be turned out with the same
expenditure of labour.
In carrying out the invention I construct the loom to receive two three or more
sets of warp threads drawn through to form as many sheds one above another and
the healds and harness are constructed and arranged to carry these several sets of
warps additional mails being provided to carry the threads above one another.
Each of the two three or more sheds are changed simultaneously.
Two three or more shuttles are employed one placed above the other the number
corresponding with the number of sets of warps or sheds. The races for these
shuttles are also placed one above the other and the shuttles are all propelled
forward through their respective sheds at the same time. The batton is. con-
structed in several parts or pieces screwed together from which one part can be
removed and replaced without disturbing or disarranging the other parts. And
the shuttles and their respective races are placed or fitted into a frame or its
equivalent which can be fitted into and removed from the batton. The shuttles
can then be filled and placed in the removable frame and when the quills of one
set of shuttles are empty all the shuttles can be removed at once and another set
supplied to take their place. Thus obviating any lengthy stoppage of the loom
whilst fresh quills are being supplied.
The slay or reed is arranged to beat up the weft in the several sheds after cach
shot of the shuttles. It is preferably divided into two three or more. divisions
corresponding with the number of the shuttles and sheds by narrow bars extending
across the dents for the purpose of dividing the different sets of warps and also of
supporting and strengthening the dents.
The invention may be applied to rack and pinion peg shot and other descriptions
of shuttles commonly employed in this class of loom.

COMPLETE SPECIFICATION.
Improvements in Small-ware Looms.
I, STEPHEN BARNWELL, of Cannon Street, Manchester, in the County of
Lancaster, Manufacturer, 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 :-
This invention relates to that class of loom in which ribbons tapes and similar
narrow articles are woven and known as smallware looms and is designed with the
object of increasing the production of the loom by providing means whereby two
three or more rows of separate and continuous fabrics can be woven superimposed

or one above the other at the same time instead of or in addition to a single fabric
such as at present produced so that a greater amount of work may be turned out
with the same expenditure of labour.
The invention consists essentially in constructing the loom with a combination
of parts arranged to receive two three or more sets or rows of warp threads drawn
through to form as many rows of sheds one above the other; two three or more
rows or sets of shuttles weaving independent fabrics; a slay or reed to separate
or divide the warps; a part of the batton which carries the shuttles movable or
detachable; and the healds constructed to carry the warps in two or more sheds
one above the other.
It will be fully described with reference to the accompanying drawings in which
sufficient of a small-ware loom is shown to illustrate my invention.

Fig. 2. end elevation.
Fig. 3. front elevation of part of slay or batton (enlarged scale).
Fig. 4. transverse section of Fig. 3.
Fig. 5. plan of same.
Fig. 6. view showing single heald or leash.
The frame work A which supports the various parts of the loom the shuttles B
and-the mechanism whereby the healds and other parts of the loom are actuated
are of ordinary construction and consequently the crank, shaft cranks, cams, and
smechanism at the end of frame for driving the shuttles are not shown in the
drawings.
The batton or slay is constructed with two three or more (preferably three)
shuttle races to receive two three or more sets or rows of shuttles B placed one
above the other the number of sets of warps or sheds corresponding therewith
all the shuttles being propelled forward through their respective sheds simul-
taneously.
The batton is further constructed in three separate parts a removable part C in
the centre which carries or supports the shuttles B and in which the shuttle
races are formed in rows one above the other; a front sliding frame D with
upright arms or brackets d which engage with the shuttles and propel them
backwards and forwards through the sheds; and a fixed frame E at the back
which carries or to which the reeds F are affixed.
The removable part C of the batton can be lifted up and removed and replaced
without disturbing or disarranging the other parts the bottom part being left open
so as not to come in contact with the warps when being removed from or placed in
position. I prefer to supply each loom with two of these removable shuttle frames
or parts and attach to each a cord G whereby they can be lifted up into a position
above the operative parts of the loom so that when the quills or pins in one lot of
shuttles become empty the removable part carrying the shuttles can be lifted out
of the batton and another one with full shuttles can be inserted to take its place
thus obviating any lengthy stoppage of the loom to supply fresh quills the empty
quills being removed and replaced whilst the shuttles are out of operation. The
cords G pass over pulleys H and I prefer to place guides at each end of the
framing by which the movable part C of the batton is when lowered guided into its
proper place..
The sliding frame D is actuated at one or both ends by the usual mechanism
and is held in position when in operation by the pivoted catches c. The catches c
are removed and the frame. D drawn forward when it is desired to remove and
replace the part C.
The reed F is divided into two three or more divisions corresponding with the
number of superimposed rows of shuttles and sheds, by narrow bars f extending
across the dents for the purpose of dividing the different sets of warps and also of
strengthening the reed or rendering it sufficiently strong to beat up weft in the
several sheds at the same time.
The healds J are each formed with two or more eyes; so that two or more rows
"

page_text: of warp threads are carried by each one above the other. Each heald thus changes
the three superimposed sheds at the one time.
The breast piece K is provided with two three or more wires over one of which
each of the separate fabrics passes when woven. The woven fabrics pass from the
wires over a roller L and from thence over a second roller M to a receiving
box N. The roller M is driven from the roller L by the strap and the fabrics
are held in contact with the roller M by pivoted levers or weights m each provided
with a pulley or runner n.
The rolls of warps I prefer to mount in a creel O at the back of the loom and
pass the threads forward over the guide rollers o o¹ as shown. Instead of placing
the creel O at the back of the loom it may be placed in any other convenient
position.
It is evident that although I prefer to place each row of shuttles immediately
one above the other one shuttle may be placed a little to the right or the left of
the one above it and the reed be placed in corresponding position.
The invention may be applied to smallware looms with any ordinary driving
mechanism for the shuttles such as rack and pinion, peg shot and other descriptions
of motions commonly employed in this class of loom.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I wish it to be understood
that I am well aware that two or more sets of superimposed shuttles with the
usual rise and fall action operated by jacquards have been employed for weaving
fabrics with colours or patterns and also for weaving ladder tapes for Venetian
blinds but such do not constitute any part of my invention, but I declare that what
I claim is :-
1. In a smallware loom the combination with a slay or batton constructed with
two or more superimposed shuttle races of two or more rows of shuttles which are
operated simultaneously, a sliding frame (or other mechanism) which operates all
the shuttles together, reeds divided into two or more divisions to maintain the warp
threads separate, healds with two or more eyes in cach leash, a breast piece with
two or more conducting wires or rods over which the finished fabric passes, and
two or more rows or sets of warp threads substantially as described and for the
purpose of weaving simultaneously two or more separate and continuous fabrics one
above the other.
2. In a smallware loom a slay or batton constructed with a loose removable part
or frame, provided with two or more superimposed shuttle races, which carries the
shuttles in combination with a sliding frame in front (or other mechanism) for
actuating the shuttles and a fixed frame at the back to which are attached the
reeds substantially as described and shown.
3. A smallware loom for weaving two or more separate continuous fabrics one
above the other having the several parts constructed and arranged in combination
substantially as described and shown.
