PROVISIONAL SPECIFICATION.
Improvements in connection with the Uprights of Jacquard Machines.
We, MAHLON PRIESTLEY, of 37 Copley Street, Great Horton, Bradford, in
the County of York, and JONAS PRIESTLEY, of Slackside, Wibsey near Bradford,
aforesaid, Machine Makers, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object the arrangement of Jacquard uprights in a
manner, that they are applicable to that class of Jacquard machines in which both
operating reciprocating grates are above the card needles, and to so construct and
combine cach pair of uprights, that one of the operating uprights acts direct on the
harness in a manner, that neck bands are dispensed with, and when any of the warp
threads require to be held up for more than one pick of the shuttle, the respective
uprights operating the raised warp threads are held up as long as required by the
pattern of the fabric.
We accomplish our object in the following manner. Each upright is formed
with a hook for engaging with the respective reciprocating grates operated in the
usual manner; and each upright is continued through holes in a grid fixed near the
bottom of the Jacquard machine, the uprights also passing through loops formed
on the card needles.
To one of each pair of uprights is secured a bar, through which the other
upright freely passes for some portion of its length, and is provided with a collar
or other projection, which, as the upright is raised, lifts the first named upright
also, to which the harness thread is attached. Should the warp thread thus raised
be required to stop up for more than one pick of the shuttle, a hook formed on the
first named upright is allowed to, rest upon a stationary rail, until it is removed
therefrom by the pattern card operating the card needle connected therewith, the
other upright passing through the bar may continue to reciprocate without affecting
the position of the raised upright or warp threads.

Improvements in connection with the Uprights of Jacquard Machines.
We, MAHLON PRIESTLEY, of 37 Copley Street, Great Horton, Bradford, in
the County of York, and JONAS PRIESTLEY, of Slackside, Wibsey, near Bradford,
aforesaid, Machine Makers, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention has for its object, the arrangement of improved Jacquard uprights
in a manner that, they are applicable to that class of Jacquard machines in which
both operating reciprocating grates are above the card needles; and to so construct
and combine each pair of uprights that, the operating uprights act on the harness
in such a way, that when the pattern of the fabric requires the warp threads to be
held up for more than one pick of the shuttle, the uprights operating the raised
n
.

page_text: warp threads are held up as long as required and liberated by the pattern card
surface of the fabric.
In explaining our invention in detail, reference is made to the accompanying
drawings in which
Fig. 1 represents a pair of Jacquard uprights constructed according to our
invention.
Fig. 2 shows one of the uprights raised and supported by a stationary bar and
the other free to reciprocate.
Fig. 3 the raised upright in position for operation by the Jacquard needle, should
the pattern surface require the upright, harness and warp threads operated thereby
to be lowered.
Fig. 4 is a view showing the relation of the uprights and needle bar on beginning
to lower the raised upright, and
Fig. 5 is a view of a portion of a card needle.
The uprights are mounted in that class of ordinary Jacquard machines, in which
both reciprocating grates for operating the uprights are above the card needles
which embrace the uprights in the manner as hereinafter described.
Each upright is formed with a hook ou the top for engaging with the respective
reciprocating grates which are operated in the usual manner, the bottom portion of
each upright sliding through a perforated plate fixed near the bottom of the
Jacquard machine, to which and to other parts of the Jacquard machine, except
the uprights and needle, we make no claim as forming part of our invention.
To one upright A. of each pair of uprights is secured a bar B. through a hole in
which the other upright C. is free to pass for some portion of its length, and is
provided with a collar or suitable stop piece projection D. in the required position,
the bottom portion of each upright being free to slide through suitable holes in
plate P. fixed to the Jacquard machine.
Should the upright A. be raised, by a cross bar of one of the ordinary recipro-
cating grates engaging with the hook A' the said upright will be lifted until the
hook E. is above the stationary rail F. and if the raised warp threads connected to
the harness cord are required to stop up for more than one pick of the shuttle, the
hook E. is allowed to engage with the stationary rail F. thus supporting the
upright A. and harness attached thereto, and the raised warp threads until such
time as the card pattern surface allows the hook E. when raised, to be pressed clear
of the stationary rail F. for descending. The other upright C. by passing freely
through or independent of the bar B. can continue to reciprocate without affecting
the raised upright A. and warp threads, so long as they are in a raised position.
Should the design of the fabric require the harness and warp threads to be
raised on the ascent of the reciprocating grate operating the upright C. by
engaging with hook C₁ then as this upright is lifted, the collar or stop projection D.
attached thereto, being on the underside of the bar B. the upright A. is raised
also, independent of the Jacquard reciprocating grate set for operating same by
hook A¹ the hook C' raising both uprights A. and C. until the hook E. is above
the stationary bar F. as shown by Fig. 3 and if the upright A. and warp threads
are required to remain up for more than one pick of the shuttle, then on beginning
to descend, the card pattern and Jacquard needle J. allows the hook E. to rest upon
the stationary bar F.
When a change of the raised warp threads is required by the pattern, the card
needles are operated in the usual manner, each needle J. embraces a pair of
uprights and is provided with two holes, through which the respective uprights
pass, the upright A. through an oblong hole K. and the upright C. through a
circular hole L. of such diameter as to hold the upright in its required position, but
allow it to pass freely through same.
The upright A. may be raised clear of stationary bar F. by either reciprocating
grate as before explained, but when the said upright is required to be lowered by
the upright C. the card cylinder allows the needle J. to be operated by the ordinary
spring in the direction of arrow, one end of the oblong hole K. being in contact

page_text: with the upright A. and the hook A' clear of the respective reciprocating grate,
the upright is sprung until the hook E. is clear of the stationary bar F. and is held
in that position by the ordinary card and needle J. until the projecting portion A'
of upright A. is in contact with the face of stationary bar F. as shown by Fig. 4 by
which the hook A' of the said upright is held in a position to allow the ascending
grate to pass.
Our invention may be effected by a modified arrangement such as shown by
Fig. 6 representing certain portions of the uprights required to explain same which
consists in making the bar B. shorter and reversing the upright C. so that the
collar or stop projection D. is on the underside of bar B. and the upright C. at end
of same clear of any hole through the said bar. The hook C¹ is also reversed, but
the operation of uprights is effected in the manner as before described.
The foregoing part of the Specification describes, and the drawings show only
one pair of uprights; it will be understood by persons conversant with Jacquard
machines that, the operation of the other uprights with which the machine is fitted
is only a repetition of that already described.
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. The upright A. and bar B. working in combination with the upright C.
arranged substantially in the manner and for the purpose as herein before set forth.
2. The uprights A. and C. as described, combined with the bar F. and needles J.
arranged substantially in the manner and for the purpose as set forth.
Dated this 7th day of January 1895.
