PROVISIONAL SPECIFICATION.
Improvements in Jacquards for Looms.
We, SOLOMON WILSON of 25 Finchley Street, Bradford, Mechanic and
MATTHEW WOODROW of Wibsey, Joiner and WILLIAM HENRY PEEL of
Hopewell House, Lightcliffe, Jacquard Machine Maker, all in the County of
York, do hereby declare the nature of this invention to be as follows:-
The object of our invention is to dispense with half of the uprights usually
employed in a double lift jacquard, and so greatly simplify the mechanism
in such.
I employ one set or half the usual number of uprights with an extra neb hook or
engaging part, (for the bars or knives of the blocks to lift the said uprights by) and
a horizontal movement of the grate, operated by a fixed tappet or projection upon
the bottom block, which acts upon a runner on the said moveable grate, the said
grate being returned by a spring or weight; or other suitable mechanism may be
used for operating the grate.
The aforesaid grate thus draws back the uprights for the other block or grate to
pass or clear, and then moves back and allows them to return into position.
The bottom fixed grid only requires half the number of slots or holes in. The
needles or uprights are easier to take out and replace than hitherto.
When required the aforesaid jacquard can be used either as a single or double
lift by operating only one block.
Dated this 23rd day of January 1893.

DESCRIPTION OF DRAWINGS.
Fig. 1. is a front elevation of our improved jacquard, both blocks being at rest
at the bottom of their traverse, and not geared up.
Fig. 2. is an end view of Fig. 1.
Fig. 3. shows our improved upright or wire detached.
Fig. 4. is a plan of part of bottom plate on which the uprights rest.

of its traverse.

page_text: We employ one set of what are technically called single uprights or wires A,
with nebs B, B and B', namely 304 of such uprights in place of double that
number. Each of the said uprights or wires are formed with an extra neb, hook
or engaging part B', for the grids or knives C of the ordinary top lifting block D,
to operate upon or engage with and lift up those of the said uprights which are
required up, so that their lowest nebs B engage with and are held up by the
fixed grid M until required down when they are released by their respective
needles and cards in the ordinary manner. The blocks D' operating only upon the
nebs B'.
The uprights not required to be lifted are pushed clear of the blocks by the
needles operated by the pattern card in the usual manner, the blocks D and D' rise
and fall vertically, oppositely in the usual manner, that is when one is rising the
other is falling.
At the top, the wires A are prolonged and pass through a plate E for steadying
purposes, there is the usual fixed grid M and pattern cylinder.
We also employ a horizontal grid or grate F, operated by fixed cams, tappets, or
projections G upon the bottom block D', which operates a runner H upon the
extra horizontal grid or grate F, moving the grate forwards horizontally in the
slots J, the said grate being returned by a spring or weight. Or other suitable
mechanism may be employed for giving the horizontal movement to the grate.
The grate having slots J, which slide upon pins or studs K, fixed to the frame L
of the jacquard.
As the block D¹ rises, or falls the grate F pushes back all the uprights, the
result being to keep all those uprights which are falling clear of the knives of the
block which is ascending at the time, and all those which are being raised, from
the knives of the block which is descending, the two blocks acting to lift certain
uprights at alternate picks according to the pattern.
We employ a bottom fixed plate E', for the uprights not required to be lifted
to rest upon, the said uprights or wires are much easier to take out and replace,
on account of there being much more space between each row.
When required
the aforesaid jacquard can be used as a single lift by operating only one of the
blocks.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In jacquards, the employment of an extra horizontal grid F, to which a
horizontal movement is imparted for pushing the uprights clear of the aforesaid
blocks, the said grid F being returned by springs, weights or other means, as and
for the purposes substantially as shown and described.
2. The combination of the single uprights or wires A, having extra nebs B',
with horizontal moveable grid F, bowl or runner H, cams or projections G, top and
bottom plates E and E, as and for the purposes, substantially as shown and
described.
