I HENRY HILL, of the Firm of Balm, Hill, and Sons, of Mansfield Road in tho
town and county of the town of Nottingham, Lace Manufacturors, do hereby
declare the nature of the said invention for "IMPROVEMENTS IN THE CONSTRUCTION
OF WARP LACE MACHINES," to be as follows:-
Each machine consists of two end standards, and one or more intermediate
standards, connected by a top tie bar, and two or more bearing rails.
and intermediate standards carry, or form bearings for, a main driving shaft, and
Both end
two rocking shafts below the needle bar, and two rocking shafts above the
needle bar.
The upper of the two first named rocking shafts, which rock in bearings carried
on the two end standards, and intermediate standards carry arms, the outer or front
ends of which are joined to an axle bar supporting tho needle bar, which rises and
falls vertically. The lower rocking shaft, (which also rocks in end bearings, and
bearings carried on the intermediate back standards) carries arins, the front ends of
which formn bearings for a shaft provided with other arms secured to a bar, to which
leads are fastened, which contain pickers or sinkers, which with their bar havo a
rising and falling, and backward and forward movements, communicated to them.
Above the needle bar, are two or more pillar bars, carried by arms, secured on the
two rocking shafts, before named, above the needle bar, these pillar bars, have a
rising and falling, and to and fro movements communicated to them, which together
with a lateral motion communicated to them by means of notched wheels or a
jacquard, cause the threads which they carry to lap round the needles, either to
form pillaring, or other looped net or fabric.
Behind the pillar bars are any required number of fancy bars, which carry the
thread for producing a pattern or fancy work upon the pillaring, net, or fabric.
The fancy bars are moved to the right and left by a jacquard, or equivalent means.

declaro the nature of my invention for "IMPROVEMENTS IN THE CONSTRUCTION
OF WARP LACE MACHINES," 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, shows a sectional view of one of my improved warp lace machines,
drawn one quarter the full size.
Figure 2, shows a sectional view of the operating instruments drawn the
full size.
Both Figures are lettered alike where necessary.
Each machine consists of two end standards A, and one or more intermediate
standards B, connected by an upper tio bar, and two or more bearing rails in the
usual way (not shown in the drawings).
Both end and intermediate standards carry or form bearings for a main driving
shaft C, and two rocking shafts D, E, below the needle bar and two rocking
shafts F, G above the needle bar. The shaft D carries arms, the front ends of
which are jointed to an axle bar D₁ which supports the needle bar 12c rrying
leads of latch needles secured to it in the usual way, the needles carried by the
bar rise and fall vertically (in a sley of the usual construction) operated by two or
more eccentrics, carried by the shaft C, each eccentric being attached to or forming
the lower end of a link Ds, having its upper end, carried by the axle bar D¹.
The shaft E carries arms, the front ends of which form bearings for a shaft E',
provided with other arms, the upper ends of which are attached to a bar E³, to
which leads containing pickers or sinkers E³, are secured, which have a rising and
falling, and backward and forward movements communicated to them, by links E,
each having its upper end carried by the shaft E¹, the lower end of each link being
operated by an eccentric carried by the shaft C.
Above the needle sley and needle bar aro two or more pillar guide bars F, carried
by the lower end of arms, which have their upper ends secured on a rocking shaft Fi
lying in the front ends of bearing armus having their back ends carried by a
rocking shaft G on which are secured two or inore pendant arms G' in which are
axle pins carrying the back ends, of two connecting links G³, G³, the front end of
the links G being hinged to the arms carrying the guide bars F, and the front ends
of the links G³ being hinged to arms G, one at each end of the machine, the lower
end of each arm being attached to, or forming an eccentric carried by the shaft C,
these eccentrics communicate a rising and falling, and forward and backward
movements to the pillar guide bars, which together with lateral motions communi-
cated to them either by means of notched cam wheels or a jacquard in the usual
way, cause the threads which they carry to lap round the needles to form pillaring
or other looped Det or fabric. Behind the pillar bars are any required number of
fancy bars which carry the threads for producing a pattern or fancy work upon
the pillaring, net or fabric, the bars H are traversed to the right and left by a
jacquard or equivalent means in the usual way.
By means of a warp machine constructed as above described, carrying latch
needles, the whole of the movements of the needle bar, the sinker or picker bar
and the pillar bars, except their lateral movements, are effected severally and in
combination by means of eccentrics on the driving shaft, the warp beams being
placed above the needle bar.

page_text: By a machine constructed as above described, I am enabled to produce a looped
net, or fabric, either in the piece, or in breadths alone, or in combination with
pillaring or fancy work, produced by the fancy bars, at a much greater speed, than
heretofore.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
"
The use of two or more pillar, or lapping bars on a warp lace machine of this
construction, the several movements of which are obtained from eccentrics,
substantially as described and illustrated in the Drawings annexed.
