Year: 1854

page_text: LETTERS PATENT to Thomas Haimes, of Melbourne, near
Invention of "IMPROVEMENTS IN WARP MACHINERY."
Derby, for the
Sealed the 23rd February 1855, and dated the 13th December 1854.
PROVISIONAL SPECIFICATION left by the said Thomas Haimes at the
Office of the Commissioners of Patents, with his Petition, on the
13th December 1854.
I, THOMAS HAIMES, of Melbourne, near Derby, do hereby declare the nature
of the Invention for "IMPROVEMENTS IN WARP MACHINERY" to be as follows:-
This Invention consists of improvements in warp machinery; first, in regard
to the instruments used when joining up the edges or selvages of two fabrics
simultaneously made of two warps in a warp machine. Heretofore in such
cases there has been found great difficulty in so arranging and working the
needles and instruments that the join of two edges or selvages shall be done
in such manner as to appear similar to the other parts of the fabric. For
this purpose, a point is applied to the needle bar at the selvage, and in the
points used to hold the work in the proper position there is at the edge or
selvage provided a hook, and these instruments are so worked as to uphold
for a time the selvage loop, and prevent its being pressed off.
The second part of the Invention consists of the application of needles with
droppers or lever covers to the beards or hooks in constructing circular warp

page_text: machines, and also in the application to circular warp machines of lever guides,
which are constructed and arranged in such manner that one set of guides
is constantly rotating in one direction, and the other set of guides is constantly
rotating in the opposite direction, and the one set of guides is formed to work
within or pass under the other set of guides, in order that the guides or each
set of guides may cach loop with the needles as they pass by them, the needles
being set round a circular or endless holder, by which the warp threads will not
only loop on to the needles and into each other, but they will produce tubular
traversed warp fabrics. -
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Haimes in the Great Seal Patent Office on the
13th June 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
HAIMES, of Melbourne, near Derby, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of December, in the year of our
Lord One thousand eight hundred and fifty-four, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Thomas Haimes, Her special licence that I, the said Thomas Haimes,
my executors, administrators, and assigns, or such others as I, the said
Thomas Haimes, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
WARP MACHINERY," upon the condition (amongst others) that I, the said
Thomas Haimes, by an instrument in writing under my hand and seal, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Thomas Haimes, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof (that is to say):-
This Invention consists of improvements in warp machinery; first, in regard

page_text: to the instruments used when joining up the edges or selvages of two fabrics
simultaneously made of two warps in a warp machine. Heretofore in such
cases there has been found great difficulty in so arranging and working the
needles and instruments that the join of two edges or selvages shall be done
in such manner as to appear similar to the other parts of the fabrics. For
this purpose, a point is applied to the needle bar at the selvage, and in the
points used to hold the work in the proper position there is at the edge or
selvage provided a hook, and these instruments are so worked as to uphold
for a time the selvage loop, and prevent its being pressed off.
The second part of the Invention consists of the application of needles with
droppers or lever covers to the beards or hooks in constructing circular warp
machines, and also in the application to circular warp machines of lever guides,
which are constructed and arranged in such manner that one set of guides
is constantly rotating in one direction and the other set of guides is constantly
rotating in the opposite direction, and the one set of guides is formed to work
within or pass under the other set of guides, in order that the guides in each
set of guides may each loop with the needles as they pass by them, the needles
being set round a circular or endless holder, by which the warp threads will not
only loop on to the needles and into each other, but they will produce tubular
traversed warp fabrics.
Having thus stated the nature of my Invention, I will proceed to describe
the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows the section of sufficient of the working parts of a warp
machine for making two fabrics simultaneously, and joining up the edges or
selvages where it is desired to do so, in order to connect the two fabrics
together, to enable me to describe my present improvements; and as the
nature and working of this class of machinery has been most fully described in
former Patents granted to me and others, it will only be necessary to describe
those parts which relate to my present improvements. It is found in working
warp machines of this description, where two full sets of guides to each needle
bar are employed, that when a selvage guide (carried by one of the outer-
most guide bars) has lapped its warp thread over the selvage needle of the
opposite set of needles, in order to connect the two fabrics on the two sets of
needles together, that, in consequence of the guide being at such a distance from
the needle, its warp thread (looped around the needle) is caused to be at such
an angle from the guide to the stem of the needle that the selvage loop slips so
low down the stem of the needle as to prevent its passing under the beard of

page_text: the needle when the needle descends and the pressing takes place; hence, the
loop, instead of being retained on the needle, is knocked over with the previous
set of loops, which causes a difference in the character of the work at that
particular part; and the object of this part of my improvements is so to arrange
apparatus or instruments that the loop on the stem of the selvage needle shall
be retained in a proper position (with the other loops) to insure its passing
under the beard of the needle, in place of being knocked over, as heretofore.
For this purpose, the point (2) outside of a selvage needle is bent into a hook
at an angle towards the needle, as shown by the separate view, Figure 2, of
a lead of points, so that when the needle bar rises, the inclined point (1),
(shewn separately at Figure 3, carried by the needle bar,) in its upward
movement acts against the hooked end of the point (2), and causes its point to
pass behind the selvage needle into a position to sustain the loop on the stem
of the needle, whilst the needles descend and take the loops under the
beards; and I would remark, that in place of employing hooks carried by the
point bars, and actuated as described, independent hooks or instruments may
be substituted for sustaining the loops on the selvage needles, to ensure their
being correctly taken under the needle beards, without departing from my
Invention, which has for its object the holding or retaining the loops on the
selvedge needles for a time to ensure their passing under the needle beards, and
prevent their being pressed off.
I will now describe my improvements in circular warp machines.
Figure 4 shows a vertical section, drawn full size, of part of a circular warp
machine constructed according to my Invention; Figure 5 shows a vertical
section, and Fig. 6 a plan, partly in section, on a smaller scale, of the lower
part of the machine, showing the mode of giving motion to the several parts
which carry and actuate the needles and lever guides; the other Figures show
the parts in other positions, the nature of which is written thereon.
a', a', is a circular or endless needle holder, around the circumference of
which are affixed the leads of needles or hooks a, a, (shown separately at
Figure 7). The points of the needles are formed into hooks, as shewn, and
there is a dropper or cover jointed on to the stem of each needle, which acts
as a substitute for the ordinary beard, and is capable of turning over on to the
hook to close in the new loop, and allow the previous loop on the stem of
the needle to slide over or be knocked off the head of the needle; by which
arrangement or construction of the needle no pressing instrument is required,
which is a great advantage in the working of circular warp machines. At the
same time I would remark that I make no claim to the construction of needles
with lever droppers or covers separately, similar needles or instruments having

page_text: been before used in the construction of other descriptions of warp machines.
b, c, are two sets of lever guides (shown separately at Figures 8 & 9), which are
also carried by circular or endless holders b, c, which are caused to rotate in
opposite directions, as hereafter described. The needles or instruments a, a,
move up and down between the fixed plates or instruments (shown separately
at Figure 10), over which the work passes, the plates or instruments being
similar to those described in the Specification of a Patent granted to me,
dated the. Fourth day of July, One thousand eight hundred and fifty-
four. Each plate in this arrangement has an angular point formed on it,
so as to allow the work to pass downwards, but which serves to prevent
the work rising up with the needles when they move up to have other loops
formed over them. The plates or instruments are fixed to and supported
by the fixed circular holder l', connected by arms to the boss ², fixed on
the central axis d. The needles a, a, are fixed to and supported by the
circular or endless holder a¹, a¹, connected by arms to the boss a², which is
capable of moving up and down on the central axis d in the following
manner a³, a³, are cross bars, connected to the boss a² and to the forked end
of the connecting rod a', which at its lower end is connected to the lever a³,
supported by the bracket a", fixed on the under side of the fixed plate or
framing of the machine, as shown; the other end of the lever a carries a
truck or roller, which is acted upon by the cam a', fixed on the axis e, by which
an up and down movement is communicated to the circular or endless needle
holder a', a', and needles a. Motion is communicated to the axis e by the toothed
wheel e¹ taking into the intermediate toothed wheel e², which receives motion
from the toothed pinion e, fixed on the crank e'. The circular holders which
carry the lever guides b, c, are caused to rotate in the following manner:-
b, c, are toothed discs or wheels, which are caused to rotate in opposite
directions around the central axis d by means of the right and left handed
screws b, c, the axes of which are supported and turn in bearings fixed to the
under side of the fixed plate or framing f. b, c, are rack wheels (fixed on the
screw axes) which receive motion at intervals from the axis e by the rotation
of the projections or fingers b, c, which act on the teeth of the rack wheels
b, c, so as to give a step by step movement to the toothed wheels b, c³, and
circular holders b, c, a distance equal to one space of the lever guides in
opposite directions. The boss of the toothed wheel c is connected to the
circular plate or disc c* by set screws, as shown, so as to cause them to
rotate together, and the toothed wheel b² and disc c* are connected respectively
to the circular lever guide holders b, c, by the supports 66, c, as shown. b, c,
are two series of bobbins on which the warp threads are wound; the bobbins

page_text: are respectively carried by and rotate with the supports b, c, and the warp
threads are conducted to the guides over the rings bs, cs, carried by the supports,
as shown. The lever guides are actuated or moved on their axes so as to loop
or cross their warp threads over the needles in the following manner:-g is a
grooved ring, into the grooves of which the tails of the lever guides enter. The
ring g is connected by uprights g* to a ring g', having arms which connect it
to the plate g², which is connected by uprights to the ring g³, fixed by brackets
g to the forked connecting rods 95, which are connected at their lower ends to
the lever g, moving on a fulcrum at g'; the other end of the lever carries a
truck or roller, which is acted upon by the cam g³, so as to raise and lower the
grooved ring g, and thus cause the lever guides to move on their axes. I
would here remark that I make no claim to the working of lever guides, this
part of my Invention simply consisting in the application of lever guides
circular warp machines, as herein explained.
Having thus described the nature of my said Invention and the manner of
performing the same, I would have it understood that I make no claim to any
of the mechanical parts separately, nor do I confine myself to the details
herein shown, so long as the peculiar character of either part of my Invention
be retained; but what I claim is,—
First, the application of points or instruments to the selvage needles to hold
or retain the selvage loops, as herein described.
And, secondly, I claim the application, as herein described of needles with
droppers or lever covers, and also of lever guides in circular warp machines.
In witness whereof, I, the said Thomas Haimes, have hereunto set my
hand and seal, this 11th day of June, in the year of our Lord One
thousand eight hundred and fifty-five.
