DESCRIPTION OF THE DRAWINGS.
Figure 1 represents a cross sectional view of a warp lace machine constructed
according to my improvements, and Figures 2 to 10, portions of the same shewn
separately and referred to hereafter.
Each machine consists of the following parts:-Two end standards A and one or
more intermediate standards B connected by a top tie bar C and two or more
bearing rails D. The standards carry bearings for a main driving shaft E, upon
which the excentrics hereafter referred to are keyed. One end of this shaft is pro-
vided with a fly wheel E' and fast and loose pulleys (not shown in the Drawing)
round which a belt is passed from any prime mover. The end and intermediate
standards carry bearing blocks for three rocking shafts F, F', and G, the length of
the machine. The shafts F and F¹ have each four or more arms F², keyed or other-
wise secured upon them, the outer or front ends of which form bearings for an axle
bar F to rock in. The axle bar is provided with four or more bracketed connecting
links F the upper end of each link forms a bearing for and is secured to an angle
bar F, to which are secured needle leads; an end view of one such lead and
needle is shewn separately at Figure 10.
The lower end of each connecting link is hinged to the front end of one of the
lower arms F2, the needle bar rising and falling vertically when operated by
two excentrics Fo, a side view of one of which is shewn with its covering plate
removed at Figure 2; an edge view with the covering plate in position is shewn at
Figure 2ª.
The rocking shaft G is provided with with four or more arms G', the front
ends of which carry a shaft G2 which is provided with arms G³, the upper ends
of which are secured to a sinker bar to which leads are fastened which carry
pickers or sinkers. An end view of one such picker or sinker lead is shewn at
Figure 8.
The sinker bar has a rising-and-falling movement communicated to it by links G*
operated by excentrics, one of which is shewn at Figure 3, and also to-and-fro
movements by links G³ operated by excentrics, one of which is shewn at Figure 4.
There is a presser bar H, to which presser bit leads (one of which is shewn in
side view, Figure 6) are secured. This bar has a to-and-fro movement given to it
by means of a rocking shaft I carrying arms to which the presser bar is secured, the
shaft being provided with links I', cach hinged to an excentric, one of which is
shewn at Figure 5. The presser bits move backwards and forwards through the
sinkers, and also forms a supporting comb for them.
Above the needle bar is a pillar bar or bars J (in the Drawing only one bar is shewn)
which is moved to the right or left by an excentric cam wheel, or by the operation
of the jacquard in the usual way, so as to lap the threads it carries round the
needles. The pillar bar or bars are carried by and slide in bearings at the lower
end of arms J' secured on a rocking shaft J2 lying in the front ends of arms secured
on a rocking shaft J3 which is carried by bearings above the top tie bar C of the
machine. The rocking shaft J2 is provided near each end with a link J4, each of
which is operated by an excentric, shewn in side view at Figure 6, which com-
municate rising-and-falling movements to the pillar bar, a to-and-fro movement
being effected by arms secured on the shaft J2 hinged to arms J³, each operated by
an excentric shewn at Figure 7.
Behind the pillar bar or bars are any required number of fancy bars K which
carry the threads for producing a pattern or openwork upon the fabric. The fancy
bars may be the ordinary steel bars, and are carried by brackets which project
from a bar K¹ secured to the standards.
The fancy bars are supplied with threads passed through a sley L from warp
beams K2, and are moved to the right and left by a jacquard or equivalent means.

page_text: The pillar bar or bars are supplied with threads from a warp beam Jo. There is
a bar M to which is secured trick leads in which the needles work, and over which
the fabric passes as it moves from the needles. The tricks also assist in knocking
the work over the needle heads.
After leaving the needles the fabric is passed round a roller N covered with card
fillets or equivalent material, and over a smaller roller to the work roller O. The
roller N is moved at a given speed and holds the fabric tight so as to assist in
forming the loop and regulate the quality.
Having thus severally described the separate parts of the machine, I will trace
the working of a course.
Suppose the needles are at their lowest point, having pressed and just knocked
over the loops, the pillar bar or bars are at their highest point, or nearly so, the
pickers or sinkers being drawn back into the comb presser with their points under
the fancy bars in position to take the threads after the fancy bars have traversed.
Upon the machine being started the whole of the operating parts begin to move,
each movement being obtained from the excentrics. The needle bar rises, the pillar
bar or bars descend, and at the same time move backwards so as to get in front of the
needle beards to place thereon the lap.
The pickers move forward and downward, selecting the fancy threads and combing
down into the pillar threads so as to place them across the needles. The pillar bar
or bars then move outwards, placing the laps on the needles which are separated
from the back or previously formed loops by the pickers or sinkers, the needles
having received the laps from the pillar bar or bars are brought down, the presser
bits move forward on to the beards of the needles. The pickers retire as soon as
the front new loops are well under the needle beards, and at the same time rising
assist to bring the previously formed loops well on to the needle beards while the
pressers are on; the needles continuing the downward motion draw the new loops
to the work and the course is finished.
By a machine constructed and operating as above described I am enabled to
employ a greater number of fancy bars than heretofore, the workman can obtain
easier access to the several parts, and the machine can be driven at a greater speed
than heretofore.
Having thus fully described the nature of my Invention, and the manner of.
performing the same, I would have it understood that I claim,-
First. The movements of the pickers or sinkers as obtained from the excentric,
shewn at Figures 3 and 4, working together.
Second. The movements of the presser bar and pressers, as obtained from the
excentric shewn at Figure 5.
Third. The rising, falling, and to-and-fro movements of the lapping bar or bars,
as obtained from the excentrics, as shewn Figures 6 and 7, working together in
conjunction with their right and left traverse.
Fourth. The general arrangement and combination of the excentrics, as shewn at
Figures 3, 4, 5, 6, and 7, working in conjunction with the excentric shewn at
Figure 2, substantially as described, and illustrated in the Drawings annexed.

seal, this Seventeenth day of January, in the year of our Lord 'One thousand
