IMPROVEMENT IN LOOMS FOR WEAVING LADDER TAPES For VENETIAN BLINDS
Year: 1885

page_text: We THOMAS FRENCH & JOHN MONKS 21 Dyer Street Manchester county of
Lancashire Smallware Manufacturers we do hereby declare the nature of our
invention for IMPROVEMENT IN LOOMS FOR WEAVING LADDER TAPES For
VENETIAN BLINDS to be as follows:-
This invention relates to that class of goods known as woven throughout Ladder
tapes for venetian blinds & the object is to simplify the Looms for weaving the said
tapes and instead of mounting two sets of Jacks or leavers on each side of the
Jacquard Machine as at present in use, we only mount one set which we fix direct
under the Jacquard Machine and by this means we can lift or sink the Heald Shafts
which fomes the cross tapes more direct, with greator ease, & with less power and
also produce more work in a given time.

Smallware Manufacturers we do hereby declare the nature of our invention for
IMPROVEMENT IN LOOMS FOR WEAVING LADDER TAPES FOR VENETIAN BLINDS and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
A. Jacquard Machine Hook of which there is sixteen in one row. B, streight
chain of which there is eight in one row C, Slack chain of which there is eight
in one row and there is one chain connected to each Hook arranged alternatly, one
streight and one slack.
D. is a cord attached to each slack chain to prevent them getting entangled.
E, one of eight Jacks which are mounted on one level and we connect two chains
to each Jack, one streight the other slack, and when the said Jacks are operated on
by the machine books and chains each Jack lifts two different heights and by this
means we can lift or sink the heald shafts which formes the cross tapes two different
heights as they are required to do.
.F, wires connected to Jacks and heald shafts for lifting the said shafts G wires
connected to Jacks above and Jacks below at one end the other end connected to
healds below for sinking the said heald shafts and the above named wires are
formed dowble so as not to impede the up and down movements of heald shafts
H, two sets of Jacks of four each with iron weights attached, for balanceing heald
shafts.
I, rod for Jacks to rest opon to prevent them raising shafts too high J, heald
shafts for carrying the warp threads which formes the cross tapes.
K, two sets of Jeks of four each mounted below and connected by wires G to
Jacks above for sinking the said heald shafts.
Having now particulary described and ascetained the nature of our said
invention and in what manner the same is to be performed we wish it to be under-
stood that we do not-confine ourselves to the precise details relative proportions or
dimensions of the various parts of the improved apparatus herein before discribed
and illustrated on the accompanying drawing as the same may be considerably
varied without departing from the inventian but what we claim as our improve-
ment in machinery for weaving ladder webs for venetian blinds is
First. Method of mounting Jacks and connecting same to Hooks in Jacquard
Machine.
Second. Mode of connecting Jacks to heald shafts balanceing and operating same
as described and illustrated on the accompanying drawing.
