IMPROVEMENTS IN LOOMS FOR WEAVING DOUBLE PILE FABRICS
Year: 1884

page_text: I HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, London in the 'County of Middlesex do hereby declare
the nature of said invention for "IMPROVEMENTS IN LOOMS FOR WEAVING
DOUBLE PILE FABRICS," to be as follows:-
This invention relates to looms for weaving double pile fabrics, so called,
composed of duplicate foundation webs united by intersecting or intermediate
threads, which, when subsequently divided, form two single fabrics each having a
pile or velvet-like surface.
The loom for weaving or producing the said double-pile fabric is provided with
an upper raceway which will effectually support the shuttle during its fight, which
may be adjusted in various ways to fit it for the most effective performance of the
work required therefrom, and which is of a construction strong and durable, and
at the same time capable of easy change and repair.
In carrying the said invention into practice I arrange at the ends of the lay,
duplicate shuttle-boxes. The lowermost shuttle-boxes are so placed that the shuttle
therefrom will be projected along the lower race way which answers to the usual
race of an ordinary loom. The upper shuttle-boxes are arranged to project their
shuttle through the suspended race of pendant fingers or prongs hereinafter more
fully set forth; the race thus provided being in the same relation to the upper
shuttle-boxes as the lower race is with reference to the lower shuttle-boxes, and
being designed to carry the shuttle used in forming the upper fabric without
permitting the said shuttle to come in contact with the warp of said fabric.
Suitable pickers or projecting devices operated in any appropriate manner are
connected with the shuttle boxes, to simultaneously project the two shuttles along
their respective races alternately in opposite directions as required in the operation
of weaving.
The top rail, is preferably made of cast metal, and has formed longitudinally
therein an internal chamber, open at the back; formed longitudinally in the under
side of this top rail is a groove rectangular in cross section. In this groove is a
bar which, in its cross section, corresponds in shape and size with the said groove,
so that it may be adjusted therein. This adjustment is provided for by means of
two or more set screws, which have broad heads, and which; passing down through
suitable holes in the bottom of the chamber are screwed into threaded sockets or

page_text: nuts formed vertically in the said bar so that by turning the said set screws by
means of a suitable wrench passed down through a suitable opening in the squared
head of each set screw, the said bar may be vertically adjusted within the groove
and fixed in position by screws. This bar is composed of several parts one of
which comprises a flat plate or relatively thin bar, to one side of which are screwed
a longitudinal series of flat blocks, each of which is firmly screwed to the side of
the thin bar by screws. Each of the flat blocks has attached to one of the sides
a pendant finger or prong having an upwardly projecting tongue which is attached
to the end of the block by means of a counter-sunk crew. That portion of the
finger or prong, immediately below the tongue, constitutes a shoulder, which fits
snugly against the under side of the thin bar. The fingers or prongs being securely
attached to the blocks by the screws, and the said blocks being in their turn firmly
attached to the sides of the thin bars by means of screws, the said fingers or prongs
are ranged in line side by side at a distance apart about equal to the length, or as
it may be termed the width, of the blocks. Furthermore ina-much as the bar, with
the thin bar and the blocks are capable of vertical adjustment with reference to
the top rail as hereinbefore explained, it follows that the fingers or prongs are
themselves, as a series, vertically adjustable, enabling the suspended race formed
by the lower ends of said fingers or prongs as hereinafter explained to be duly
adjusted in relation with the path of the upper shuttie as the same is thrown to
and fro from one to the other of the upper shuttle boxes The lower end of each
of the fingers or prongs is provided with an elongated bulb-shaped vertical spur
which, on account of its rounded contour, prevents the yarns of the upper warp
from catching thereon during the operation of the weaving. In the rearmost side
of this vertical spur is formed a horizontal groove or notch. Projecting backward
from the lower part of each of the fingers or pro igs; is an arm in which, in a
parallel direction with that of the horizontal notch, is formed an opening from
which to the lower outer surface of the said arm, extends a relatively narrow slit.
The fingers or prongs being placed side by side with their flat lateral surfaces
parallel and at substantially regular distances apart, as here before ex lained, it
follows that the horizontal notches of the said fingers or prongs will be substantially
coincident or in the same horizontal line, and that, in like manner, the openings
with their narrow slots will be coincident, or in substantially the same line. The
shuttle of the upper shuttle-box has at one of its sides a rib, which, in diameter
and cross section, corresponds in size and shape with that of the openings, and
which is longitudinally connected with the adjacent rear edge of the shuttle by a
narrow neck or strip which, in diameter and shape, corresponds substantially with
that of the narrow slit. Provided longitudinally at the front of the shuttle is a
spline which in size and cross section corresponds substantially to that of the
horizontal notches, the said parts, and the shuttle itself, being so proportioned
that while the rib may pass within and through the opening, the spline may pass
within and through the horizontal notches. The shuttle, and its boxes, being
arranged in due relation with the race thus provided by the lower ends of the
fingers or prongs, the said shuttle in its flight from one of the boxes to the other,
is suspended out of contact with the warp, inasmuch as the rear of the shuttle is
supported by the passage of the rib through the openings while the front of the
shuttle is supported by the passage of the spline in and through the horizontal
notches. What may be termed a skeleton race is thus provided for the support of
the said upper shuttle during its flight.

page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co, Patent Agents
Southampton Buildings, in the County of Middlesex do hereby declare the
nature of my invention for "IMPROVEMENTS IN LOOMS FOR WEAVING DOUBLE-PILE
FABRICS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:—
"
This invention relates to the production of double pile fabrics, so called, composed
of duplicate foundation webs united by intersecting or intermediate threads, which,
when subsequently divided, form two single fabrics each having a pile or velvet-
like surface.
The loom for weaving or producing the said double pile fabric preparatory to
the separation of the two fabrics thereof as herein before indicated is provided with
an upper raceway which will effectually support the shuttle during its flight,
which may be adjusted in various ways to fit it for the most effective performance
of the work required therefrom, and which is of a construction strong and durable
and at the same time capable of easy change and repair.

Figure 8 is a sectional view on the line z, z, Figure 6.
Figure 8 is a detail view of one of the shuttles.
A is the reed of a loom and B is the top rail of the said reed. At the ends of
the lay are duplicate shuttle boxes C, D. The lowermost shuttle boxes C are so
arranged that the shuttle therefrom will be projected along the lower race way a
which answers to the usual race of an ordinary loom. The upper shuttle-boxes D
are arranged to project their shuttle through the suspended race of pendant fingers
or prongs G hereinafter more fully set forth; the race thus provided being in the
same relation to the upper shuttle-boxes D, as the race a is with reference to the
lower shuttle boxes C and being designed to carry the shuttle used in forming
the upper fabric without permitting the said shuttle to come in contact with the
warp of said fabric. Suitable pickers or projecting devices, operated in any
appropriate manner, are connected with the shuttle boxes C and D, to simul-
taneously project the two shuttles along their respective races alternately in
opposite directions, as required in the operation of weaving.
The top rail B is preferably made of cast metal, and has formed longitudinally
therein an internal chamber a open at the back as shown at a¹.
Formned longitudinally in the underside of this top rail is a groove b, rectangular
in cross section as shown in Figure 3. Placed in this groove b is a bar F which in
its cross section corresponds in shape and size with the said groove b, so that it

page_text: may be adjusted bodily up and down therein This adjustment is provided for by
means of two or more set screws c, which bave broad heads c' as shown in Figure 3
and which, passing down through suitable holes in the bottom of the chamber a*,
are screwed into threaded sockets or nuts formed in the bar F so that by turning
the said set screws c by means of a suitable wrench passed down through suitable
openings f, the bar F may be vertically adjusted with the groove band fixed in
position by screws a¹¹.
The bar F is composed of several parts (as represented in Figure 4) one of which
is a flat plate or relatively thin bar g to one side of which is secured, by means of
screws i, a series of flat blocks h. Each of the blocks has attached to one of its
sides a pendent finger or prong, G, having an upwardly-projecting tongue k which
is attached to the end of the block by means of a counter-sunk screw m
portion of the finger or prong G immediately below the tongue constitutes a
shoulder f which fits snugly against the under side of the plate g as more fully
indicated in Figure 8.
That
It will be seen that the fingers or prongs G being securely attached to the
blocks by the screws m and the said blocks h being in their turn firmly attached
to the sides of the plate g by means of screws, i, the said fingers or prongs G are
ranged in line, side by side, at a distance apart about equal to the length, or as it
may be termed, the width, of the blocks has more fully indicated in Figure 2.
Furthermore, inasmuch as the bar F composed of the plate g and the blocks h is
capable of vertical adjustment with reference to the top rail B as hercinbefore
explained, it follows that the fingers or prongs G are themselves, as a series,
vertically adjustable, enabling the suspended race formed by the lower ends of said
fingers or prongs G, as hereinafter explained, to be duly adjusted in relation to the
path of the upper shuttle as the same is thrown to and fro from one to the other of
the upper shuttle-boxes D.
The lower end of each of the fingers or prongs G is provided with an elongated
bulb-shaped vertical spur n which on account of its rounded contour, prevents the
yarns of the upper warp from catching thereon during the operation of weaving.
In the rearmost-side of each vertical spurn is formed a horizontal groove or notch r.
Projecting backward from the lower part of each of the fingers or prongs G is an
arm m, in which, in a direction parallel with that of the horizontal notch r, is
formed an opening, from which to the lower outer surface of the said arm m³
extends a relatively narrow slit 11. The fingers or prongs G being placed side by
side with their flat lateral surfaces parallel and at substantially regular distances
apart, as hereinbefore explained, it follows that the horizontal notches r of the
said fingers or prongs will be substantially coincident, or in the same horizontal
line, and that in like manner the openings with their slits will be coincident
or in substantially the same line.
The shuttle H of the upper shuttle box has, as represented in Figure 8ª, at one of
its sides a rib s, which, in diameter and cross section, corresponds in size and shape
with that of the openings r¹, and which is longitudinally connected with the
adjacent rear edge of the shuttle H, by a narrow neck or strip a¹ which, in diameter
and shape, corresponds substantially with that of the slit 011, Provided longi-
tudinally at the front of the shuttle H is a spline t, the size and cross section of
which correspond substantially with those of the notches r, the said parts and the
shuttle H itself being so proportioned, that while the ribs may pass within and
through the opening, the spline t may pass within and through the notches r.
The shuttle H and its boxes D being arranged in due relation with the race thus
provided by the lower ends of the fingers or prongs G, the said shuttle in its flight
from one of the boxes D to the other is suspended out of contact with the warp
inasmuch as the rear of the shuttle is supported by the ribs which passes through
the openings while the front of the shuttle is supported by the spline t which
passes in and through the notches T. What may be termed a skeleton race is thus
provided for the support of the said upper shuttle H during its flight.
