IMPROVEMENTS IN JACQUARDS
Year: 1884

page_text: I HENRY SWIFT, of the firm of Swift and Wass, of New Basford in the county of
Nottingham, Bobbin and Carriage Makers and Machinists, do hereby declare the
nature of the said invention for "IMPROVEMENTS IN JACQUARDS," to be as follows:
Above each top sley of a spring dropper jacquard, I secure standards or brackets
to which a pair of vertical plates are secured, each pierced to receive needles, rods,
or wires which are held securely in position by cotter pins or otherwise, between
the needles, rods, or wires, the spring portion of the droppers slide, the square stem
portion of each dropper is provided with a projecting stud or pin, these studs or
pins when the jacquard is driven at a great speed strike the needles, rods or wires
before named, and are thus prevented by them from rising too high, which has
frequently heretofore, been the case. By such means considerable damage hereto-
fore experienced is avoided, and the jacquard can with safety be driven at a much
greater speed.

page_text: I HENRY SWIFT of the Firm of Swift and Wass of New Basford in the County
of Nottingham Bobbin and Carriage Makers and Machinists do hereby declare
the nature of the said invention for IMPROVEMENTS IN JACQUARDS and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front view and Figure 2 a sectional view of the top sley A of a
spring dropper jacquard of the usual construction.
Above which I secure standards or brackets B to which a pair of vertical
plates C C are secured each pierced to receive flat rods D, the number of which vary
according to the width of the jacquard to which my improvements are applied,
the flat rods D are held securely in position by a plate E, placed at the back of
the heads of the rods, being pressed upon by a spring F at each end, the plate E
has a hole at each end to receive the heads of the screws which secures the back
vertical plate C to the brackets, when a dropper or series of droppers require to be
withdrawn or inserted it is only necessary to press back one of the springs F, turn
up the plate E and withdraw the flat rod D which is nearest to the left side of the
dropper or series of droppers to set it or them free, between the flat rods the spring
portion of the droppers which are of the usual form and construction slide, the
square stem portion of each dropper is provided with a projecting stud or pin G
these pins when the jacquard is driven at a great speed strike the lower side of the
flat rods and are thus prevented from being raised too high, or from being thrown
out of their sley, which has frequently heretofore been the case, by such means
considerable damage heretofore experienced is avoided, and the jacquard can with
safety be driven at a much greater speed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I claim the brackets B
vertical plates C C flat rods D the holding plate E springs F and studs G projecting
from the square stem of spring droppers the whole placed above the top sley A of
& spring dropper jacquard substantially as described and illustrated in the drawings
annexed.
Dated this twentieth day of February 1884.
