IMPROVEMENTS IN THE STRIPE MOTION OF LOOMS FOR WEAVING STRIPED FABRICS."
Year: 1874

page_text: LETTERS PATENT to Henry Cockerham, of Bradford, in the County
of York, Stuff Manufacturer, for the Invention of "IMPROVEMENTS
IN THE STRIPE MOTION OF LOOMS FOR WEAVING STRIPED FABRICS."
PROVISIONAL SPECIFICATION left by the said Henry Cockerham at
the Office of the Commissioners of Patents, with his Petition,
on the 24th January 1874.
I, HENRY COCKERHAM, of Bradford, in the County of York, Stuff
Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE STRIPE MOTION OF LOOMS FOR WEAVING STRIPED
FABRICS," to be as follows:-
This Invention relates to certain improvements in the application and
arrangement of the stripe motion for weaving striped fabrics, and con-
sists of a four threaded worm wheel keyed or otherwise fastening on to

page_text: the top or crank shaft at the fly wheel end of any loom used for weaving
stripe patterns, this wheel works into a pinion fixed upon an upright shaft,
at the other end of which is fixed a bevel wheel working into another bevel
wheel fixed on to shaft carrying tappets, the number and configuration
of the same being suited to the pattern intended to be woven. Upright
shaft is carried by fixings attached to the side of frame of loom, and the
tappet shaft is carried by bearings fixed on to the top of the same frame.
The treddles are so fixed as to work into the tappets at right angles to
the tappets and tappet shaft, the treddles being connected to healds
by gearing composed of wire and strings in the usual way. The treddles
are kept on the surface of the tappets by small weights below the healds.
My Invention can be applied to a left or right-handed loom with equal
facility.
In the arrangement hitherto in use the required motion was obtained
from the low shaft of the loom by means of cog wheels working cams,
the treddles being kept on the cams by springs. The whole of this
arrangement being under the warp was difficult of access. My arrange-
ment being on the top of the loom is casily accessible, and being in
fewer parts is more easily kept in repair.
SPECIFICATION filed in pursuance of the conditions of the Letters 2
Patent, and of an Order of the Lord Chancellor by the said Henry
Cockerham in the Great Seal Patent Office on the 28th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
COCKERHAM, of Bradford, in the County of York, Stuff Manufacturer,
send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of January, in the
year of our Lord One thousand eight hundred and seventy-four, in
the thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Henry Cockerham, Her 3
special licence that I, the said Henry Cockerham, my executors, admini-
strators, and assigns, or such others as I, the said Henry Cockerham,
my executors, administrators, and assigns, should at any time agree

page_text: 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 "Im-
PROVEMENTS IN THE STRIPE MOTION OF LOOMS FOR WEAVING STRIPED FABRICS,"
upon the condition (amongst others) that I, the said Henry Cockerham,
my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, 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 on or before the Thirty-first day of July, One thou-
sand eight hundred and seventy-four.
NOW KNOW YE, that I, the said Henry Cockerham, do hereby declare
the nature of my said 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 relates to certain improvements in the application and
arrangement of the stripe motion for weaving striped fabrics, and
consists of a four threaded worm wheel keyed or otherwise fastening on
to the top or crank shaft at the fly wheel end of any loom used for
weaving stripe patterns, this wheel works into a pinion fixed upon an
upright shaft, at the other end of which is fixed a bevel wheel working
into another bevel wheel fixed on to shaft carrying tappets, the number
and configuration of the same being suited to the pattern intended to be
woven. Upright shaft is carried by fixing attached to the side of frame
of loom, and the tappet shaft is carried by bearings fixed on to the top
of the same frame. The treddles are so fixed as to work into the tappets
at right angles to the tappets and tappet shaft, the treddles being con-
nected to healds by gearing composed of wire and strings in the usual
way. The treddles are kept on the surface of the tappets by small
weights below the healds. This Invention can be applied to a left or
right handed loom with equal facility.
In the arrangement hitherto in use the required motion was obtained
from the low shaft of the loom by means of cog wheels working cams,
the treddles being kept on the cams by springs. The whole of this
arrangement being under the warp was difficult of access. My arrange-

page_text: ment being on the top of the loom is casily accessible, and being in
fewer parts is more easily kept in repair.
I now proceed to describe the apparatus employed and shewn in the
accompanying Drawings, in which like parts are indicated by the same
letters and figures.
'
Fig. 1 is an elevation of my apparatus looking from end of loom;
Fig. 2 is an clevation looking from back of loom.
A, A, A, is the framework of loom; B is the crank or fly wheel shaft
which is driven in the usual way and revolves in bracket B' secured to
frame A. C is a four threaded worm keyed on shaft B, into which is
geared worm wheel D keyed on upright shaft E, the bottom part of
which revolves in footstep E' forming part of bracket F secured by
bolt F¹ to another bracket G standing at right angles to frame A and
secured thereto by bolt G¹. H is a bracket for supporting top end of
upright shaft E which is secured to frame A by bolt H'; J is a bevel
wheel keyed on end of shaft E¹; K is another bevel wheel gearing into J
and keyed on to shaft K', revolves in bracket L secured to frame A by
bolt L'. M, M, M, M, are tappets secured on shaft K¹ which is left
sufficiently long to put on the requisite number of tappets to produce
the desired pattern in piece to be woven; N is a stud secured by nut N¹
to projecting part L³ which is cast to and forming part of bracket L.
0, 0, 0, 0, are tappet levers working on centre stud N; O¹ are holes
for adjusting the travel of healds; P is a bracket secured to A by means
of bolt P¹; Q is a stud secured to bracket P by nut Q¹; R, R, R, R, are
small grooved pullies working on stud Q, over which passes cords S, 8,
one end of which is secured to lever O at O¹, the other end to the
healds in the usual way.
Action of Machine.-B, the crank shaft, is driven in the usual way;
the worm wheel C secured to the same revolves, and gearing into worm
wheel D turns upright shaft E and bevel wheel J, gearing in bevel
wheel K keyed on shaft K³, thus causing the tappets M, M, M, M, M,
which are keyed on the same to revolve; S, S, the cords fastened to the
healds in the usual way passes over pullies R, and secured at O' on
levers O, the bottom part of which are kept in contact with tappets by
means of small weights, not shewn in Drawings, fixed to bottom of

page_text: healds, thus causing levers to follow tappets and give the required
motion to healds and warps.
In witness whereof, I, the said Henry Cockerham, have hereunto
set my hand and seal, this Twentieth day of July, in the year
of our Lord One thousand eight hundred and seventy-four.
Witness,
JOHN WAUGH,
Engineer,
Bradford.
