page_text: We, PAUL SPEAK, of the firm of Paul Speak and Sons, Spinners and Manu-
facturers and JOHN PICKLES, Designer, both of Mountain Mills, Queensbury near
Bradford in the County of York, 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 to weave simultaneously in the same loom, two
pieces of cloth of the same or a different colour, or of different materials, which
may be connected together by the selvage or woven entirely separate.
This may be accomplished by placing in the loom two separate warp beams, or
by obtaining the warp for both the top and bottom piece from one warp beam;
and alternately shedding the warp by reversing the order of the tread for the top
and bottom cloths; the tread continuing through the selvages when the cloths are
woven separate from each other, but altering the tread at the selvages when the
two cloths are there united.
In order to make clear the invention, we have appended hereunto a pattern
diagram, in which the lines A, represent the warp threads of the top cloth, and the
lines B, the warp threads of the bottom cloth, both of which are actuated by an
ordinary heald or jacquard machine.
For producing two cloths of the pattern shewn by the diagram, the warp threads
are manipulated in the following manner; we will first describe them in connection
with the bottom cloth in which the "shed" is formed by dividing them as
follows:-
The warp threads denoted by the crosses on the weft line C at A' B¹ and A' are
raised, the other warp threads indicated by the circles B* being lowered; all the
warp threads across the piece being actuated in this order forms the "shed" for
the first pick. For the next or return pick on weft line D, the "shed" is formed
by raising those warp ends denoted by the crosses at A¹ A¹ and B¹ and by lowering
the warp threads or ends indicated by the small circles B2, which operation is
repeated across the piece thus, forming the "shed" for the second or return pick of
the bottom cloth.
For the top cloth, the order of treading the warp threads is reversed; in the first
pick of the top cloth denoted by the weft line E, the top warp threads indicated by
crosses as at A¹ are raised, the others where the circles B² A² and B² appear being

lowered; the same is repeated for the width of the piece, thereby forming the
shed" for the shuttle to pass through. For the return pick denoted by the weft
line F, the shed is formed by raising the warp threads at the cross A¹ and lowering
those where the small circles appear as at A2 B2 and B³ between which the shuttle
is driven, thus completeing the return pick of the top piece.
By continuing the treading of the warp threads the entire width of the piece
including the selvages, two separate pieces are woven simultaneously, but by
treading the body of the piece in the manner described, and the selvage warp
threads lifted alternately otherwise than the body of the cloth, the two cloths are
united together at the selvages.
By having the two warps of different material, or colour, and the weft of the
two pieces likewise; cloths of a different colour or material are woven simul-
taneously, the top cloth may be light like gauze or canvas cloth, and the bottom
heavy and of a different colour shews through the top cloth when made into dress
goods, thereby giving a pleasant appearance.
The diagram shews the method of manipulating the warp threads for one design
of cloth, in which there are three threads up and one down, or visa versa, but we
wish it to be understood, that two fabrics may be woven in which more warp
threads are required to form the pattern, but in every case the treading of the
warp threads for the top cloth are reverse to those of the bottom cloth.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is
The weaving of two distinct cloths which may be separate or united at the
selvages by operating the warp threads substantially in the manner described.
