CERTAIN IMPROVEMENTS IN HEALDS' EMPLOYED IN LOOMS FOR WEAVING."
Year: 1860

page_text: LETTERS PATENT to Alfred Augustus Larmuth, of Salford, in the County
of Lancaster, Dentist, for the Invention of "CERTAIN IMPROVEMENTS IN
HEALDS' EMPLOYED IN LOOMS FOR WEAVING."
PROVISIONAL SPECIFICATION left by the said Alfred Augustus Larmuth
at the Office of the Commissioners of Patents, with his Petition, on the
31st January 1860.
I, ALFRED AUGUSTUS LARMUTH, of Salford, in the County of Lancaster,
Dentist, do hereby declare the nature of the said Invention for "CERTAIN
IMPROVEMENTS IN 'HEALDS' EMPLOYED IN LOOMS FOR WEAVING," to be as
follows:-
The Invention relates to the healds or harness which contain a loop or eye
through which the warp threads pass, and by which the warps are raised and
lowered to effect the necessary "shedding" for the passage of the shuttle in
weaving.
The improvement consists in the novel employment of round wires of any
description of metal for such "healds" or harness, having the loop or eye
formed therein by stamping or flattening a part about the middle until it
assumes the form of a long ovoid, and in such flattened portion perforating or
forming the loop or eye, which may be either circular, oval, or other shape, as
required. The wires may be electrotyped or galvanized, or otherwise coated
to give the eyes a smooth surface, and prevent injury to the warps, and are to
be set or fixed in bands of india-rubber or india-rubber cloth to render them
slightly elastic in action.

by the said Alfred Augustus Larmuth in the Great Seal Patent Office on
the 30th July 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
AUGUSTUS LARMUTH, of Salford, in the County of Lancaster, Dentist, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of January, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Alfred Augustus Larmuth, Her special licence that I, the said Alfred Augustus
Larmuth, my executors, administrators, and assigns, or such others as I, the
said Alfred Augustus Larmuth, 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 Inven-
tion for "CERTAIN IMPROVEMENTS IN 'HEALDS
EMPLOYED IN LOOMS FOR
WEAVING," upon the condition (amongst others) that I, the said Alfred
Augustus Larmuth, 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 within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Alfred Augustus Larmuth, 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 (that is to say):-
In making the healds or harness employed in weaving for making or
forming the shed, I use a continuous round or flattened wire of any description
of metal, and where the loops or eyes for the warp threads to pass through are
required to be formed, I stamp or flatten the wire, and afterwards make a per-
foration, either circular, oval, or of any other desired shape, and in order to
prevent the shifting of the barness I stamp or flatten the wire at those parts
where it passes over the heald shafts, which operations of stamping and per-
forating are performed either by hand or suitable machinery. The wires may
be electrotyped or galvanized, or otherwise coated, to give the loops or eyes a

page_text: smooth surface, in order to prevent injury to the warps, and they may be set
or fixed in bands or tubes of india-rubber or other suitable elastic material to
render them slightly elastic in their action.
Having thus fully described the nature of my said Invention, and the manner
in which the same is to be performed, I desire it to be distinctly understood
that I do not claim the use of flattened wire in short lengths, as I know such
has been already adopted; but I claim as my Invention, and which to the best
of my knowledge and belief has not been hitherto used within the realm, the
manufacture of healds or harness used in weaving fabrics of continuous round
or flattened wire; if round it must be flattened at the places where the loops
or eyes are to be made for the warp threads to pass through, the said loops or
eyes being made by perforating the wire at the places so flattened.
In witness whereof, I, the said Alfred Augustus Larmuth, have here-
unto set my hand and seal, this Twenty-fifth day of July, in the year
of our Lord One thousand eight hundred and sixty.
ALFRED AUGUSTUS LARMUTH. (L.S.)
Signed, sealed, and delivered by the within-
named Alfred Augustus Larmuth, in the
presence of
E. J. HUGHES, Patent Agent,
Manchester.
