Year: 1858

page_text: LETTERS PATENT to Richard Longden Hattersley, of Keighley, in the
County of York, for tho Invention of "IMPROVEMENTS IN LOOMS FOR
WEAVING."
Sealed the 23rd November 1858, and dated the 24th May 1858.
PROVISIONAL SPECIFICATION left by the said Richard Longden Hattersley
at the Office of the Commissioners of Patents, with his Petition, on
the 24th May 1858.
I, RICHARD LONGDEN HATTERSLEY, of Keighley, in the County of York, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN LOOMS
FOR WEAVING," to be as follows:-
This Invention relates to looms to which rotary shuttle boxes are employed,
and consists,-
Firstly, in the employment of portable hooks or catches for connecting the
lever or levers, which is or are acted upon by the cam on the picking or
treading shaft, with the levers, which operate the rotary shuttle boxes, such
hooks being connected to the said levers at the time only when the boxes
require to be changed, by means of taper rods alone, or in connection with
suitable cams or levers, which are operated by the jacquards or other indi-
cating apparatus.
Secondly, in having the first-named lever or levers so attached at the fulcrum

page_text: ends as to be capable of lifting therefrom, if the shuttle does not box or not
go properly into the box, or from any other cause when the shuttle boxes are
fast and not capable of rotating, which lever or levers is or are so constructed
and arranged as to act upon the strap guide, and stop the loom.
Thirdly, in working the rotary shuttle boxes by means of right and left-
hand ratchet wheels and catches, which catches are kept out of gear therewith
at all times, except when acted upon by the before named lever or levers,
through the medium of a rod or rods for turning or changing the boxes.
Fourthly, in the application of a friction roller or pulley to the spring pin,
which acts on the star wheel attached to the rotary boxes for holding them in
a proper position.
Fifthly, in the employment of friction rollers or pullies at the end of the
shuttle boxes, instead of the plates now in use for pushing the shuttle back
into the box.
And sixthly, in having a groove formed in the bottom of each shuttle
iakon tong to move in to keen the nicker steady.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Longden Hattersley in the Great Seal Patent Office
on the 23rd November 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
LONGDEN HATTERSLEY, of Keighley, in the County of York, send greeting.
WHEREAS IIer most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of May, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Ierself, Her heirs and successors, give and grant unto me, the
said Richard Longden Hattersley, Her special licence that I, the said Richard
Longden Hattersley, my executors, administrators, and assigns, or such others
as I, the said Richard Longden Hattersley, 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 LOOMS FOR WEAVING," upon the condition (amongst
others) that I, the said Richard Longden Hattersley, 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

page_text: performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Richard Longden Hattersley, 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, reference being had to the accompanying two Sheets of
Drawings, and the letters of reference thereon, similar letters referring to the
same parts in each Figure.
This Invention relates to looms to which rotary shuttle boxes are employed,
and consists,
Firstly, in the employment of portable hooks or catches for connecting the
lever or levers, which is or are acted upon by the cam on the picking or treading
shaft, with the levers which operate the rotary shuttle boxes, such hooks being
connected to the said levers at the time only when the boxes require to be
changed by means of taper rods alone, or in connection with suitable cams
or levers, which are operated by the jacquards or other indicating apparatus.
Secondly, in having the first named lever or levers so attached at the
fulcrum ends as to be capable of lifting therefrom, if the shuttle does not box
or not go properly into the box, or from any other cause when the shuttle
boxes are fast and not capable of rotating, which lever or levers is or are so
constructed and arranged as to act upon the strap guide and stop the loom.
Thirdly, in working the rotary shuttle boxes by means of right and left-
hand ratchet wheels and catches, which catches are kept out of gear there-
with at all times, except when acted upon by the before-named lever or levers
through the medium of a rod or rods for turning or changing the boxes.
Fourthly, in the application of a friction roller or pulley to the spring pin,
which acts on the star wheel attached to the rotary boxes for holding them in
a proper position..
Fifthly, in the employment of friction rollers or pullies at the end of tho
shuttle boxes instead of the plates now in use for pushing the shuttle back
into the box.
And sixthly, in having a groove formed in the bottom of each shuttle
box for the picker tang to move in to keep the picker steady.
Sheet 1 of the said Drawings represents an end elevation of so much or of
such parts of an ordinary loom as are necessary in order to illustrate my said
Invention. A is a lever having its fulcrum at the end a (which will be
afterwards referred to); Bis a cam or tappet fixed on the end of the picking
or treading shaft of the loon which gives motion to the said lever; C, D, aro

page_text: portable hooks or catches hinged to the aforesaid lever one on each side, the
bottom ends of which pass through a separate slot hole in the plate E fixed to
the loon frame, so that the levers are capable of oscillating therein; F, G,
are two rods with taper ends, or with fixings thereon wedge-formed, each of
which also pass through or are capable of sliding freely in the slot plate E;
the upper ends of these rods are here shewn as broken off, because I do not
claim any particular means of operating them, but they may be raised and
lowered by a jacquard machine, or any other suitable indicating apparatus
such as are now in use for similar purposes; H, I, are two levers with their
fulcrums near the middle at J, in one end of each are fixed studs, and to the
other ends are attached or hinged two rods K, L, which extend upwards, and
are connected to two short levers M, N, for working or turning the rotary
shuttle boxes, which are more clearly explained herein-after by detail
Drawings; O is a bell crank lever for casing the rotary boxes when turning;
P is a pulley and frame, which is capable of sliding up or down in a slot
formed in one arm of the lever O when operated by the jacquard or other
indicating means, so as to be brought into contact with the cam Q affixed on
the treading shaft. The other end of this lever is attached by a rod to the
spring pin or shuttle box holder; R is a pin jointed to the lever A, with a
friction pulley betwixt the jointing, which pin is capable of sliding in the
two lugs, loops, or bearings of the fixing S, which is fixed to the loom frame;
T is a cap for preventing the pin R and fulcrum of the lever A from rising,
being held down by means of a spring U, except when the shuttle is fast in
the box, or from any other cause, when the other end of the lever cannot rise,
the
сар T will be forced up by the lever A, and by means of a stud t fixed in
the said cap the strap guide V will be "knocked off" and thus stop the loom.
Fig. 1, Sheet 2, is a side view of a portion of one of the portable hooks
and taper rods, with part of the slot plate, and end of the lever A drawn full
size; Fig. 2, shews the fulerum end of the lever A with the pin R, fixing S,
cap T, spring U, strap guide V, and the stud t; Fig. 3 is a plan of the same
half size. W, Fig. 4, is a section of a set of six rotary shuttle boxes with
grooves in the bottom of each box for the picker tang to move in for holding
the picker steady; X is a section of the fixing or frame which carries tho
rotary shuttle boxes, and underneath is a short shaft Y, on which is fixed the
short levers M, N, and jointed to which are two catches b, c, for operating the
right and left-hand ratchet wheels Z, Z. To the frame Y, are also attached
two inclines d, e, which a small lug or projection on the side of each of the
catches b, c, slide or are pushed up by the levers M, N, whereby the catches
are raised off or out of contact with the ratchet wheels when not required to

page_text: turn the boxes, but when pulled by the levers drop into gear with the ratchet
wheels. It will be observed that the rods K, L, and levers M, N, with their
respective catches operate or turn the ratchet wheels in contrary directions,
consequently one catch must be out of gear when the other is operating.
Motion is communicated from the shaft Y to the rotary shuttle boxes by spur
gear wheels; Fig. 5 is a side elevation of the ratchet wheels, catches, &c.;
Fig. 6 is a plan of the shuttle boxes half size, shewing the application of the
pulleys f, g, instead of guard plates for pushing the shuttle back into the
box, and also shewing the grooves h in the bottom of the boxes with a cor-
responding slot in the plate which carries the pullies f, g, for receiving and
guiding the picker tang into the boxes again. Figure 7, shews the friction
roller or pulley on the spring pin which acts on the star wheel for holding
the boxes in position.
Having thus described the nature of my Invention, and the manner in
which the same is to be performed, I would have it distinctly understood that
I do not confine myself to the precise details as herein set forth; but I claim,―
Firstly, the portable books, and taper rods or wedges.
Secondly, having the fulcrum end of the lever A. capable of lifting, and at
the same time to knock off the strap guide and stop the loom.
Thirdly, the method of working rotary shuttle boxes by right and left-handed
ratchet wheels and catches, in combination with rods and levers.
Fourthly, the application of a friction roller to the spring pin or shuttle
box holder.
Fifthly, the employment of friction rollers at the end of the shuttle box.
And sixthly, the use of a groove in rotary shuttle boxes for the picker
tang to move in.
In witness whereof, I, the said Richard Longden Hattersley, have here-
unto set my hand and scal, this 22nd day of November, in the year of
our Lord One thousand eight hundred and fifty-eight.
Witness,
RICHARD LONGDEN HATTERSLEY. (L.S.)
