PROVISIONAL SPECIFICATION.
Improvements in or applicable to the Reeds of Looms, and the Mode
of Using the same.
I DAVID SMITHIES of 21 Rectory Road, Higher Crumpsall, near Manchester,
Heald Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My said invention relates to a novel method of constructing and using the reed of
a loom for the purpose of producing certain effects in the design or appearance of
the cloth.
According to my said invention I arrange the dents in the reed so that some of
them are inclined at an angle to the others so as to leave interspaces of a triangular
shape having the vertices of some of the triangles at the top while others are at the
bottom of the reed. In certain cases all the triangles may point upwards or all
downwards according to the pattern to be produced.
The warp threads destined to form the particular effect pass through the said
triangular interspaces. By raising or lowering the reed in suitable guides in the
slay the narrower or wider portions of the triangular interspaces in the reed come
into action and the warp threads therein are either crowded together or have room
to spread laterally. The width of the effect may therefore be determined by the
vertical position of the reed in the slay.
The up and down movements of the slay may be effected by hand as the weaving
proceeds or such movements may be obtained automatically as for example from a
chain of cards and a peg barrel as in the case of the mechanism used for operating
the shuttle boxes of drop box looms.
In some cases I divide or subdivide the triangular spaces by one or more central
dents.

COMPLETE SPECIFICATION.
Improvements in or applicable to the Reeds of Looms, and the Mode
of Using the same.
I DAVID SMITHIES of 21 Rectory Road, Higher Crumpsall, near Manchester,
Heald 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 :-
My said invention relates to a novel method of constructing and using the reed
of a loom for the purpose of producing certain effects in the design or appearance
of the cloth.
According to my said invention I arrange the dents in the reed so that some of
them are inclined at an angle to the others so as to leave interspaces of a triangular
shape having the vertices of some of the triangles at the top while others are at the
D

page_text: bottom of the reed. In certain cases all the triangles may point upwards or all
downwards according to the pattern to be produced.
The warp threads destined to form the particular effect pass through the said
triangular interspaces. By raising or lowering the reed in suitable guides in the
slay the narrower or wider portions of the triangular interspaces in the reed come
into action and the warp threads therein are either crowded together or have room
to spread laterally. The width of the effect may therefore be determined by the
vertical position of the reed in the slay.
In the accompanying drawing
Fig. 1 illustrates one form of a reed made in accordance with my said invention.
Fig. 2 shows a modification thereof having triangular interspaces in which are
inserted one or more dents a dividing such interspaces.
The positions and dispositions of the triangular interspaces may be varied
at will.
The up and down movements of the reed may be effected by hand as the weaving
proceeds or such movements may be obtained automatically as for example from a
chain of cards and a peg barrel as in the case of the mechanism used for operating
the shuttle boxes of drop box looms.
Such a vertically sliding reed with triangular spaces may be used in combination
with a Jacquard or shaft machine according to the particular pattern to be
produced.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
th
1. The use in combination with a loom of a reed whose dents are set so as to form
triangular passages for the warp and which is so mounted as to be slid up and down
in the slay as the weaving proceeds substantially as and for the purpose set
forth.
2. The process of producing fancy effects in weaving by using a vertically sliding
reed some of the dents of which are not parallel to each other substantially as set
forth.
3. A reed for a loom baving the dents set at angles to each other so as to leave
triangular interspaces for the passage of the warp.
4. As a new article of manufacture a fabric having a pattern produced by the
successive and alternate crowding together and spreading of the warp threads
substantially as set forth.
Dated this 16th day of January 1895.
