PROVISIONAL SPECIFICATION.
Improvements in Jacquard Apparatus.
I, JOHN GEBBIE of Kilmarnock in the County of Ayr, Lace Manufacturer, do
hereby declare the nature of this invention to be as follows:-
This invention has for its object to improve Jacquard mechanism by duplicating
the action of the needles, by dispensing with the ordinary springs used in conjunction
with these needles and by utilizing the upstanders to act as springs for returning the
needles to their normal positions, each upstander for this purpose being formed with
one, two or more hooks facing in opposite directions alternately.
In carrying out my invention the horizontal needles of the Jacquard apparatus
are pointed at both ends, and each end is acted on alternately by pattern cards
placed over barrels in the usual manner. Each needle has an upstander passed
through it which has formed in addition to the usual hook at its upper end, one or
more hooks at required distances apart throughout its length the hooks in each
plane constituting a row facing in opposite direction to those immediately above or
below. Each row of hooks is acted on alternately by a separate frame of knives,
the said frame being laid in an inclined plane. The plane of each series of hooks
of the upstanders is inclined parallel to the plane of the knife frames, that is to say,
the hooks of each upstander is on a level above or below its neighbour in the row
corresponding to the distance vertically between any two rows of adjacent needles
of the Jacquard apparatus.
The knife frames are actuated from the loom in the usual way.
The upstanders besides being guided by passing them through the Jacquard
needles, are further guided by being passed through holes in an inclined guide frame
and at their lower ends they are returned upwards so as to form a loop to which the
cords for operating the knitting needles of the loom are tied. The returned end of
each upstander is bent at a right angle to constitute a stop to prevent the upstander
dropping too low down and the loop is of sufficient length to prevent its being
withdrawn from the guide when the upstander is raised to the highest position by
the action of the knives.
The lowest row of horizontal needles has the upstanders at the lowest part of the
inclined plane passed through it and so on to the uppermost row of needles and the
highest upstanders are reached. The two hooks on each upstander being faced in
opposite directions, and the frames of the knives being correspondingly arranged when
the unselected needles have been pushed back by the action of the pattern cards at
one side of the apparatus, their upstanders will be sprung against the knives of the
frame which is at rest, whilst the other knife frame raises the selected needles the
said upstanders springing back to their normal positions taking the unselected
needles with them when the cards pass out of action.

Improvements in Jacquard Apparatus.
I, JOHN GEBBIE of Kilmarnock in the County of Ayr, Lace Manufacturer, 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:-
My invention has for its object to improve Jacquard mechanism by duplicating
the action of the needles by dispensing with the ordinary springs used in conjunction
with these needles and by utilizing the "upstanders " to act as springs for returning
the needles to their normal positions each "upstander" for this purpose being
formed with hooks facing in opposite directions alternately.
I attain these objects by the mechanism illustrated on the accompanying
drawings in which
Figure 1 is a side elevation of so much of a Jacquard mechanism as is necessary
to shew the improvements and
Figure 2 is a plan of some of the needles drawn to a larger scale.
In carrying out my invention the horizontal needles a of the Jacquard apparatus
are pointed at both ends, and each end is acted on alternately by pattern cards
placed over barrels b in the usual manner. Each needle a has an upstander c passed
through an eye d made in it and each upstander has formed upon it in addition to
the usual hook e at its upper end a further hook at the required distance apart.
The hooks in each plane constitute a row which faces in the opposite direction to
the hooks in the plane immediately above or below. Each row of hooks e el has a
separate knife frame provided in conjunction with it the said frames being laid in
an inclined plane. The plane of each series of hooks e e¹ of the upstanders c is
inclined parallel to the plane of the knife frames that is to say, the hooks of one
upstander are on a level above or below the hooks of its neighbour in the row
corresponding to the distance vertically between any two horizontal planes or rows
of adjacent needles a of the Jacquard apparatus.
The knife frames fare actuated from the loom in the usual way.
The upstanders c besides being guided by passing them through the Jacquard
needles a and through the knife frames fare further guided by being passed through
holes in an inclined guide frame g and at their lower ends they are returned
upwards so as to form loops h to which the cords i also connected to the fabric
producing mechanism of the loom are tied. The returned end of each upstander c
is as seen at j bent at a right angle to constitute a stop which prevents the upstander
dropping too low down and the loop is of sufficient length to prevent its being
withdrawn from the guide g when the upstander is raised to the highest position by
the action of the knives k.
The horizontal needles a in the lower row have the upstanders c at the lowest
part of the inclined plane passed through them and so on in succession with each
plane of needles until the uppermost row and the highest upstanders are reached.
The two hooks e el on each upstander being faced in opposite directions and the
series of knives k.being correspondingly arranged or inclined, when the unselecetd
needles have 'been pushed back by the action of the pattern cards at one side of the
apparatus, the upstanders of the needles will be sprung against the knives k of
the frame which is at rest and so that their hooks e or el shall be moved out of the
path of the knives k of the other frame which by acting upon the hooks e or e¹ of
the upstanders of the selected needles raises or lifts them. The upstanders of the
unselected needles spring back to their normal positions taking the unselected
needles with them when the cards cease to act upon them.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. In Jacquard apparatus the combination of a series of superposed rows of
horizontal needles pointed at and operated by Jacquard cards from both ends a
series of upstanders each passing through an eye in a horizontal needle and having
in its length two hooks the hooks facing in opposite directions alternately, a
separate knife frame for each plane or row of hooks the knives of the frame which
is temporarily at rest acting as abutments against which one hook of the upstanders
of the unselected needles is sprung so as to free its other hook from the corre-
sponding knife of the other temporarily operating frame and a guide through which
the returned lower ends of the upstanders, which constitute loops are passed
substantially as described.
2. In a Jacquard apparatus an upstander having in its length hooks facing
alternately in opposite directions each acted upon by a separate knife frame and
having its lower part returned to form a loop the end being bent over to constitute
a stop substantially as and for the purpose described.
