Year: 1870

page_text: LETTERS -PATENT to John Keighley, of Bradford, in the County of
York, Machine Maker, Richard Shephard, of the same Place,
Mechanic, and James Robinson, of Bradford aforesaid, Manager,
for the Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING."
"
Sealed the 2nd May 1871, and dated the 30th November 1870.
PROVISIONAL SPECIFICATION left by the said John Keighley, Richard
Shephard, and James Robinson at the Office of the Commis-
sioners of Patents, with their Petition, on the 30th November
1870.
We, JOHN KEIGHLEY, of Bradford, in the County of York, Machine
Maker, RICHARD SHEPHARD, of the same Place, Mechanic, and James
ROBINSON, of Bradford, aforesaid, Manager, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING,” (to be
as follows) :-
This Invention relates, firstly, to means of guiding the picker in
the shuttle box, and the improvements consist in dispensing with
the picker spindle, and in lieu thereof applying to each side of the

page_text: said box a guide or projecting flange, by preference of smooth glass
or other smooth material such as metal coated with porcelain, and
such as will not be subject to heat by friction or would require
lubrication, our object being to dispense with the use of oil or other
lubricant which the picker spindle now in use requires, which oil or
lubricant is detrimental to the fabric by being thrown upon it by the
action of the picker; also in the application of an additional spring for
holding the picker in the box in a parallel line with the aforesaid picker
guides or flanges, which spring is capable of adjustinent by set screws
to any amount of friction or pressure required to be put upon the
pickers.
4
Secondly. The Invention relates to the construction of the pickers,
and consists in having them made to fit the aforesaid guides and in
'forming a recess on one or both sides at the part where it strikes the
'shuttle for the insertion of buffalo hide, which is held therein by means
'of a thin metal ring fixed thereon with screws so that when worn out
new hide may be readily inserted; also we form a recess at each end of
the shuttle box into which we insert india-rubber or other clastic
material for the picker to strike against to prevent damage thereto; also
in forming a recess in or an opening through the front part of the shuttle
box 'to admit the weft and thereby prevent its being dirtied or chafed by
the action of the shuttle.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Keighley, Richard Shephard, and James
Robinson, in the Great Seal Patent Office on the 27th May
1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
KEIGHLEY, of Bradford, in the County of York, Machine Maker,
RICHARD SHEPHARD, of the same Place, Mechanic, and JAMES ROBINSON,
of Bradford, aforesaid, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of November, in the
year of our Lord One thousand eight hundred and seventy, in the
thirty-fourth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said John Keighley, Richard

Shephard, and James Robinson, Her special licence that we, the said
John Keighley, Richard Shephard, and Jaimes Robinson, our exe-
cutors, administrators, and assigns, or such others as we, the said John-
Keighley, Richard Shephard, and James Robinson, 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 "IMPROVEMENTS IN▸
LOOMS FOR WEAVING," upon the condition (amongst others) that we, the
said John Keighley, Richard Shephard, and James Robinson, our
executors, or administrators, by an instrument in writing under our
or their, or one of their hands and seals, should particularly, describo.
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. John Keighley,, Richard Shephard,
and James Robinson, 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 accom-
panying Sheet of Drawings (that is to sax):→
This Invention relates, firstly, to means of' guiding the picker in
the shuttle box, and the improvements consist in dispensing with
the picker spindle and in lieu thereof applying to each side of the
said box a guide or projecting flange by preference of smooth glass.
or other smooth material such as metal coated with glass or porcelain
and such as will not be subject to heat, by friction or would require
lubrication, our object being to dispense with the use of oil or other
lubricant which the picker spindle now in use requires, which oil or
lubricant is detrimental to the fabric by being thrown upon it by the
action of the picker; also, in the application of an additional spring
for holding the picker in suitable position in the box, which spring is
capable of adjustment by set screw to any amount of friction or pressure
required to be put upon the pickers.
i
Secondly. The Invention relates to the construction of the pickers,
and consists in having them made to fit the aforesaid guides, and
in forming a recess on one or both sides at the part where it strikes

page_text: the shuttle for the insertion of buffalo hide which is held therein by
means of a thin metal ring fixed thereon with screws so that when
worn out new hide may readily be inserted; also we form a recess
at each end of the shuttle box, into which we insert india-rubber or
other elastic material for the picker to strike against to prevent damage
thereto; also in forming a recess in or an opening through the front
part of the shuttle box to admit the weft or permit it to enter
and thereby prevent its being dirtied or chafed by the action of the
This Invention will be readily understood by reference to the accom-
panying Sheet of Drawings, wherein Fig. 1 is the front elevation of a
shuttle box with the first part of our improvements applied thereto;
Fig. 2 is a plan; and Fig. 3 is a cross section of the same,
A are the guides or projecting flanges, which are of glass by pre-
ference, but may be of metal coated with glass or porcelain or of other
material not liable to heat by friction and that would not require
lubrication, as one of the great objects in this part of the Inven-
tion is to avoid the use of any lubricant for the picker guides and
thereby prevent grease spots being made on the fabrics during the
process of weaving them; B is the additional spring for stopping
the picker in its return stroke and holding it at a distance from the
box cnd so that the picker becomes a buffer or retarder to the shuttle.
This spring is attached at one end to a lever O, which is hinged to a
bracket D fixed under the lay E, and projects upwards through it into
the shuttle box for the picker to come into contact with, the other
end of the said spring being attached by screw and wing nut F to
another bracket G, so that by means of this adjusting screw the pressure
of the spring, or the amount of resistance required may readily be
regulated or adjusted.
The second part of this Invention as relates to the construction
of pickers, is shewn at Figs. 4 and 5, which shew the form thereof full
size made suitable to fit the guides in the shuttle box and also shewing
the recess for inserting therein a piece of buffalo hide H for the shuttle
tip to strike against which is secured or held in its place by a ring of
metal I. It will be observed that by this construction pickers can be
readily repaired by removing the worn picco of hide and inserting new

india-rubber or other elastic material J for the picker to strike against
and the recess or opening K made in the front of the shuttle box to
receive the weft yarn are shewn in Figs. 1, 2, and 3, and their use will
be easily understood,
In witness whereof, we, the said John Keighley and James Robin-
son, for and on behalf of ourselves and the said Richard Shephard,
have hereunto set our hands and seals, this Twenty-sixth day of
May, in the year of our Lord One thousand eight hundred and
seventy-one,
Signed, sealed, and delivered by
the within-named John Keighley
and James Robinson, in the pre-
sence of
