IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1886

page_text: We WILLIAM THOMPSON, of Park Bridge Mills, Blackburn, in the County of
Lancaster, Cotton Manufacturer, and ROBERT HEAPS, of Park Bridge Mills,
Blackburn aforesaid, Mechanic, do hereby declare the nature of my said invention
for "IMPROVEMENTS IN LOOMS FOR WEAVING" to be as follows:-
The object of this invention is to render looms designed for the weaving of
wide fabrics better adapted for the weaving of narrow cloths by use of inter-
changeable parts combined with appliances hereinafter described.
We employ for the weaving of narrow cloths a separate slay comprising slay
beam, or "race" reed, and shuttle boxes, the latter being provided and combined
with adjustable brackets, for connecting the slay to the heads of the slay swords -
The knocking off, and weft fork lever, for narrower loom, is proportionately
longer-The driving pulley is also changed so as to speed the loom and picking
motion to the desired increase of speed in proportion to the narrower width of
cloth or fabric being woven.
The use of the above combined appliances admits of the ready alteration of wide
looms without cutting off, shafts, cross rails, going and other parts, and also the
ready adaptation of such looms to the weaving of wider cloths or fabrics when
required for such.

We WILLIAM THOMPSON of Park Bridge Mills, Blackburn Manufacturer and
ROBERT HEAPS of Park Bridge Mills aforesaid Manager do hereby declare the
nature of our invention for IMPROVEMENTS IN LOOMS FOR WEAVING 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 render looms designed for the weaving of
wide fabrics better adapted for the weaving of narrow cloths by use of inter-
changeable parts combined with appliances hereinafter described.
We employ for the weaving of narrow cloths a separate slay comprising slay
beam or "race"-reed and shuttle boxes; the latter being provided and combined
with adjustable brackets for connecting the slay to the heads of the slay swords.
The knocking off" and weft fork lever for narrower loom is proportionately
longer.

The driving pulley is also changed so as to speed the loom and picking motion
to the desired increase of speed in proportion to the narrower width of cloth or
fabric being woven.
The use of the above combined appliances admits of the ready alteration of wide
looms without cutting of shafts, cross rails, "going" and other parts, and also the
ready adaption of such looms to the weaving of wider cloths or fabrics when
required for such.
Such being the nature and object of this our invention the following is a
complete description of same reference being had to the accompanying drawings
forming a part of this specification in which
Figure 1, is a plan view of hand rail adjustable bracket and lengthened weft
fork lever.
Figure 2 is a back view in elevation of bracket fixed on hand rail and spindle
stud.
Figure 3 is an end view of same.
The other figures on sheet 2 are side elevation plan and end elevation of the
bracket.
According to this our invention we employ for the weaving of narrow cloths a
shuttle box 1, and slay provided with and combined with adjustable bracket 2 for
connecting the slay to the heads of the slay swords-The adjustable bracket 2
being secured by bolt 3 to the spindle stud 3s and by bolt 4 to the slay sword 4.
The under part 5 of the hand rail 6 is cut away more than ordinary so as to
receive the bracket 2.
The knocking off and weft fork lever 7 is made longer than ordinary so that the
weft fork 8 is in the right position in relation to the weft thread 9 and fork grate
by means of this adjustable bracket 2, we are enabled to move the spindle stud 3
(see Figure 2) nearer the centre of the loom and thereby to make the loom capable
of weaving narrow cloth or fabric.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be used we declare that what
we claim is
.
1. The separate or detachable slay adjustable brackets stud and slay swords all
in combination and for purpose herein described and as illustrated by annexed
drawings.
2. The separate or detachable slay adjustable brackets slay swords and weft
fork all in combination and as herein fully described and illustrated by annexed
drawings.
