Year: 1867

page_text: LETTERS PATENT to Richard Longden Hattersley, of the Firm of Geo.
Hattersley & Sons, of Keighley, in the County of York, Machine
Makers, and John Smith, of Sutton Cross Hills, in the same County,
for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
Sealed the 11th October 1867, and dated the 12th April 1867.
PROVISIONAL SPECIFICATION left by the said Richard Longden
Hattersley and John Smith at the office of the Commissioners of
Patents, with their Petition, on the 12th April 1867.
We, RICHARD LONGDEN HATTERSLEY of the Firm of Geo. Hattersley &
Sons, of Keighley, in the County of York, Machine Makers, and JOHN
SMITH, of Sutton Cross Hills, in the same County, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN LOONS FOR WEAVING"
to be as follows:-
This invention relates to means or apparatus for operating healds or heddles
in looms for weaving, and our object is to enable looms to be worked at a
greater speed and with more steadiness of action than is generally obtained
with ordinary heald machines, shedding motions, or jacquard apparatus. We

page_text: accomplish this object by means of a series of bell-crank levers equal in
number to the number of healds or heddles employed, such levers being
hinged upon a fulcrum or shaft supported in suitable bearings, one arm of
each lever is attached to one of the healds or heddles, and the other is hinged
to the middle of a swing bar, to each end of which swing bar is hinged a hook
or catch capable of taking on to a knife or lifting bar when placed in suitable
position.
We employ two knives or lifting bars which are operated simultaneously
in opposite directions by means of levers and a connecting rod attached
thereto, and to a crank or eccentricfixed on the tappet shaft or elsewherefrom
which the same speed can be obtained The hooks or catches are arranged in
two sets so that each catch in each set may be operated upon by its proper
knife, and each set of catches is selected and placed into or out of position by
means of a cylinder and pug-legs or cards which require moving every
alternate prick only and operate upon a series of levers according to their
arrangements, which levers actuate a series of slidable wires or pins placed
in contact with the hooks. In the above arrangement we require springs or
weights for pulling down the healds.
This apparatus is also capable of adaptation for working the healds or
heddles so as to dispense with springs or weights for pulling down the healds,
for which purpose we employ double the number of bell-crank levers, swing
bars, hooks, or catches, and knives or lifting bars, one half of these parts being
arranged to raise and the other half to depress the healds by connection with
the usual levers underneath the healds.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Longden Hattersley and John Smith in the Great
Seal Patent Office on the 12th October 1867.

in the County of York, Machine Makers, and JOHN SMITH, of Sutton Cross
Hills, in the same County, .send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of April, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors give and grant unto us, the
said Richard Longden Hattersley and John Smith, Her special licence that

page_text: we, the said Richard Longden Hattersley and John Smith, our executors,
administrators, and assigns, or such others as we, the said Richard Longden
Hattersley and John Smith, our 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 "Iм-
PROVEMENTS IN LOOMS FOR WEAVING," upon the condition (amongst others)
that we, the said Richard Longden Hattersley and John Smith, our executors
or administrators, by an instrument in writing under our, or their, or one of
our or 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
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said Richard Longden Hattersley and
John Smith, do hereby declare the nature of our said Invention, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement and accompanying Sheet of
Drawings, (that is to say):-
This Invention relates to means or apparatus for operatinghealds or heddles
in looms for weaving, and our object is to enable looms to be worked at a
greater speed and with more steadiness of action than is generally obtained
with ordinary heald machines, shedding motions, or jacquard apparatus. We
accomplish this object by means of a series of bell crank levers equal to
the number of healds or heddles employed, such levers being hinged upon
a fulcrum or shaft supported in suitable bearings; one arm of each lever
is attached to one of the healds or heddles and the other is hinged to
the middle of a swing bar, to each end of which swing bar is hinged a hook
or catch capable of taking on to a knife or lifting bar when placed in suitable
position.
We employ two knives or lifting bars which are operated simultaneously
in opposite directions bymeans of levers, and a connectingrod attached thereto
and to a crank or eccentric fixed on the tappet shaft or elsewhere from which
the same speed can be obtained. The hooks or catches are arranged in two
sets, so that each catch in each set may be operated upon by its proper knife,
and each set of catches is selected and placed into or out of position bymeans
of a cylinder and peg-lags or cards which require moving every alternate pick
only and operate upon a series of levers according to their arrangement,

page_text: which levers actuate a series of slidable wires or pins placed in contact with
the hooks. In the above arrangement we require springs or weights for pulling
down the healds.
This apparatus is also capable of adaptation for working the healds or
heddles so as to dispense with springs or weights for pulling down the healds,
for which purpose we employ double the number of bell crank levers, swing
bars, hooks or catches, and knives or lifting bars, one-half of these parts being
arranged to raise the other half to depress the healds by connection with
the usual levers underneath the healds.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 represents the front elevation of a loom frame with our improved
apparatus applied thereto.
A are the bell crank levers which are hinged on a shaft or rod A', supported
on the frame B, one arm of each lever is attached by a cord A² to one of the
healds or heddles C, the other arm being attached to a swing bar D, to each
of which are hooks or catches D' and D'. These catches drop and catch on
the knives or lifting bars E and E' when not held out of contact therewith
by the rods or pins F resting upon weighted levers G, which levers are
lifted by pegs G¹ projecting from the peg lags G. The knives E are supported
by and capable of sliding in grooves formed in the frame B and operated by
rods E and E³, connected to a three-armed lever H and hinged to the frame,
and oscillatory motion given thereto by a rod I connected to a crank J fixed
on the low shaft of the loom. It must be understood that each hook or catch
has its separate rod F and lever G with its own line of pegs or peg holes in
the lags G. The cylinder G³ carrying the peg lags is turned by a pawl or
catch G', a lever G, which is hinged to the frame, and a rod G° connected to
the lever H. By this apparatus any of the healds can be arranged to be
lifted and pulled down when liberated by springs in the usual way, or by the
use of an additional set of bell crank levers K, as shewn at Fig. 2, with
bottom levers K' connected thereto, and to the healds, whereby the usual
springs can be dispensed with. It will be observed that cards or other
indicating or actuating means may be used instead of the peg lags with this
apparatus.
Having thus described the nature of our said Invention, and shewn the
manner in which the same is to be or may be performed or carried into
practice, we would have it understood that we do not confine ourselves to the
precise details herein set forth, but we claim the combination and arrangement
of apparatus for operating healds or heddles, substantially as herein shewn

page_text: and described, whether indicated by peg-lags, cards, or other similar indi-
cating means.
In witness whereof, I, the said Richard Longden Hattersley, for and
on behalf of myself and the said John Smith, have hereunto set my
hand and seal, this Eighth day of October, One thousand eight
hundred and sixty-seven.
RICHARD L. HATTERSLEY. (L.S.)
