WILLIAM LEONARD ELLIS and SIDNEY AQUILA ELLIS, of Dudley Hill, near
Bradford, in the County of York, Spinners and Manufacturers. " IMPROVE-
MENTS IN JACQUARDS EMPLOYED IN WEAVING AND IN APPARATUS CONNECTED
THEREWITH."
Our Invention relates to improvements in the harness of jacquards, by which
means we can alter the sets without casting ends out, and which allows of weaving
any fine or coarse sets; it has been impossible heretofore to weave with a fine set
out of a coarse harness, as only a coarse set could be woven with in casting out from
a fine harness.
For this purpose we employ long flat wire mails instead of the present small eye
mails. The flat wire mails are pierced with a series of small holes to allow, when the
harness is opened, of the passage of the warps through any of the holes to keep the
warps level and prevent wavy warps, which would prevent weaving.
To open the harness to any required set we employ an apparatus which is
constructed with a frame which is secured on brackets fitted to the top rail of the
loom, and on each side of the harness the frame is made with a long opening to
allow the harness to pass through, and also when the harness is opened. The cumber
board instead of being made in one piece is made in sections, and each separate
length is made to hold any suitable pattern. The separate cumber boards are fitted
on the top of the frame, through which passes the harness, and receive a sliding
backward and forward action to open or close the harness when required, and give
more or less opening, according to requirements. For this purpose we secure on the
front and back of each cumber board a plate having bosses or lugs, and the lug
towards the centre of the loom is cut with a screw thread, the other with a square
hole through which passes freely a square rod, Between each set of cumber board
plates having lugs are fitted studs cut on the outside with screws, and which screw
in the threads cut in the lugs; the studs are also cut with square holes to allow
the square rod to pass freely through them. The cumber board fitted in the centre
of the loom is fixed, and the lugs of the plates are both cut with square holes. The
rods are fitted at one end with wing handles to turn the rod right and left, or the
rods can be actuated by having small wheels fitted on the ends of the rods which
gear into an intermediate wheel actuated by a bandle. By turning the rods they

page_text: actuate the screwed studs which screw in the threaded lugs opening outwards on each
side of the fixed cumber board the harness; the rods are turned the reverse way to
bring in the harness.
From a fine set of harness to produce a coarse set we actuate the square rods
which give an outward motion to each cumber board right and left of the fixed
centre cumber board, and when the sets are altered from fine to coarse, and
according to the distance, the cumber boards are moved outwards, causes the lifting
up of the mails and consequently of the holes in the mails, so that the warps are
passed through holes to keep the warps level.
The number of cumber boords employed is regulated by the number of sets 1
required.
