Year: 1874

page_text: LETTERS PATENT to John Keighley, Plumber, of Bradford, in the
County of York, for the Invention of "IMPROVEMENTS IN PICKERS USED
Scaled the 21st August 1874, and dated the 21th February 1874.
PROVISIONAL SPECIFICATION left by the said John Keighley at the
Office of the Commissioners of Patents, with his Petition, on the
24th February 1874.
I, JOHN KEIGHLEY, Plumber, of Bradford, in the County of York, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
PICKERS USED IN Weaving, and Apparatus thereFOR," to be as follows, that
is to say :-
My Invention relates to employing pickers made of metal, having
tubes through which pass the spindles, and having lock picking boxes
in which is placed the sizing or any other suitable material; also in
employing check springs and direct levers for checking the pickers.
For this purpose I employ a metal tube, through which passes tho
spindle. This tube is bushed at cach end with gun metal bushes, in

page_text: .
which works the spindle, thereby reducing friction. In the space left
between the bushes are placed cloth or felt washers, forming a lubricater
for the spindle. An opening is formed in the top of the tube, leaving
the cloth or felt washers exposed to allow of the oiling. The picking
strap is fixed round the tube. Two arms are cast on the bottom of the
tube, joining the lock picking box to the tube; this box is round,
having a flange cast on one side, keeping the picking material in its
place; this picking material is formed of washers of sizing, india-rubber,
and leather, or any other suitable material. The washers are placed in
the following order :-Sizing, leather, india-rubber, and sizing. These
washers are firmly fixed in the lock box by means of a lock, which is
formed by having in the box two ribs with faces at an angle in which
fits a lock made to pass through the opening left by the ribs, and having
also angular picces forming a thread of a screw, which fits in the ribs.
The back part of the lock is made with an opening, in which fits a key,
allowing the turning of the threaded pieces on the ribs locking the
picking material in the box, and keeping it firmly fixed. On the bottom
part of the box are cast projecting picces forming steadying heels.
I may construct my pickers with a tube and two guides, through
which pass steel rods forming guide rods; these guides havo bushes
fixed in each end to reduce friction. I also employ a spring attached to
the going part, checking the picker after the shuttle is gone, and I use
a direct lever fixed on the under side of the going part, having leather
or sizing traversing across the spindle box bottom to catch the bottom
part of the picker, thereby checking the picker and preventing its sudden
stoppage, doing away with check straps.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Keighley in the Great Seal Patent Office on.
the 24th August 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN 30
KEIGHLEY, Plumber, of Bradford, in the County of York, sond
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fourth day of February, in thio.

page_text: 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 suc-
cessors, give and grant unto me, the said John Keighley, Her special
licence that I, the said John Keighley, my executors, administrators,
and assigns, or such others as I, the said John Keighley, 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 PICKERS USED IN WEAVING, AND APPARATUS THEREFOR," upon the condition
(amongst others) that I, the said John Keighley, 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 John Keighley, 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 Drawing hereto.
annexed, and to the figures and letters marked thereon, that is..to
say :-
The said Invention relates to employing pickers made. of metal,
having tubes through which pass the spindles, and having lock picking
boxes in which are placed washers made of sizing, india-rubber, and
leather; also in employing checks with springs and direct levers for
checking the pickers. For this purpose I employ a metal tube (by pre-
ference of malleable cast iron), through which passes the spindle. This
tube is bushed at each end with gun metal bushes, through which works
the spindle, thereby reducing friction. The picking strap is fixed
round the tube. Two arms are cast on the bottom of the tube, joining
the lock picking box to the tube; this box is round, having a flange
cast on one side, keeping the picking material in its place; this picking
material is formed of washers of sizing, india-rubber, and leather. The"
washers are firmly fixed in the box by means of a lock, which is formed
by having in the box two ribs with faces at an angle, in which fits a lock

page_text: made to pass through the openings left between the ribs, and having
also angular pieces forming a thread of a screw which fits in the ribs.
The back part of the lock is made with an opening in which fits a key,
allowing the turning of the threaded pieces on the ribs locking the
picking material in the box, and keeping it firmly fixed. On the
bottom part of the box is cast a projecting piece forming a steadying
heel.
T
I may construct my pickers with a tube and two guides, through
which pass steel rods forming guide rods; these guides have bushes
fixed to each end to reduce friction. I also employ a check with
springs; this check is fitted to the going part of the loom, and checks
the picker after the shuttle is gone, doing away with check straps. I
also employ direct levers fixed on the under side of the going part; to
these levers is attached a leather strap, traversing the spindle box
bottom to catch the bottom part of the picker, thereby checking the
picker and preventing the sudden stoppage thereof, doing away with
check straps.
But in order to enable my improvements to be better understood I
will proceed to more particularly describe the same by reference to the
accompanying Drawing, in which Figure 1 represents a sectional front
elevation of a metal picker; Figure 2, sectional side elevation ;
Figure 3, side elevation; Figure 4, front elevation; and Figure 5, plan.
of the same.
Figure 6 represents a sectional front clevation of a check; Figure 7,
front elevation; Figure 8, side view; and Figure 9, plan of the same.
Figure 10 represents a front elevation of the going part of a loom with
check and check gear; and Figure 11, side elevation of the same.
Similar letters of reference, are used in all the Figures to represent
similar parts.
A, tube having gun metal bushes C screwed in and made taper,
through which passes the spindle B. The picking strap is fixed round-
the tube. Underneath the tube A are cast two arms or ribs F, joining
the lock picking box G to tlic tube, and at one end of the picking box is
cast a rim or flange H to keep the picking material in its place; this
picking material is formed of washers made of sizing I, india-rubber J,
and leather K. The washers are firmly fixed in the picking box G by

page_text: means of the lock L, which is screwed in or made with a thread of a
screw, which fits into ribs cast at angles in the box. The back part of
the lock L is made with an opening, in which fits a key, or with a screw
slot, in which may be placed a screwdriver to allow the turning of the
threaded pieces on the ribs, or of screwing in the lock, locking tho picking
material in the box, and keeping it firmly fixed. On the bottom part of
the lock box G is cast a projecting picce M, forming a steadying heel;
this projection is made with openings, in which may be fitted pieces of
sizing for the purpose of giving a lining and keeping the picker steady
in the groove of the going part end of the loom.
Figures 6, 7, 8, and 9 represent a spring check made of metal (by pre-
ference of malleable cast iron), which is fitted to the going part of the
loom. O, cylindrical outside metal box, in which slides the insido
box P; this box has a boss Q cast on it, in which fits the spindle B.
Inside the box P are placed india-rubber rings R, or steel springs,
through which passes the spindle. On the outside of the box O is placed
a leather washer to deaden the blow of the picker when striking. Tho
picker striking against the leather causes the india-rubber washers R to.
be compressed, thereby checking the picker. S, guide working in the
spindle guard attached to the sword end of the loom.
Figures 10 and 11 represent a check and check gear acting on the
picking box. U, going part of the loom, on the under side of which is
fixed a bracket V, having bosses W, through which works a; small
shaft X. A spring is fitted on this shaft to prevent it moving sideways,
and on this shaft are fixed, by means of, set screws Y, levers Z and Z!;
to these levers is fixed a leather strap A', forming the check. To the
lever Z is fitted by a screw and washer a piece of leather B', having a
wire D' attached to it, such wire having at one end a hook E', to which
is attached a leather strapping to join a similar wire on the other shuttle
box. The wire D' is guided by a leather support F'. The check strap A'
is fastened to the levers Z and Z' by screws and washers G', and an
opening H' is formed in the back of the going part to allow the check
strap A' to work. The picking box striking against the check strap A¹
receives a check, and at the same time pulls by means of the leather
connections attached to the wires D' the other check strap back, bringing
it into gear for the picking box when it arrives, and checking it. On the
top of the going part is fitted a break I made of steel, having at the end
á fixed piece of leather or sizing J', on which strikes the picker.

page_text: Having thus described my improvements and the best means I am
acquainted with for carrying the same into effect, I would have it
understood that I do not confine myself to the precise details shewn and
described, as these same may be varied without departing from the
peculiar character of the Invention, but what I do claim is,-
Firstly. The construction and employment of metal pickers made with
lock boxes, in which are placed picking materials made of sizing, india-
rubber, and leather, substantially as herein-before described and repre-
sented in the accompanying Drawing.
Secondly. The construction and employment of metal spring checks
for checking tho picker, substantially as herein-before described and
represented in the accompanying Drawing.
Thirdly. The employment of direct levers fitted on the under side of
the going part of the loom, having leather straps forming a check, and
provided with a break, substantially as herein-before described and repre-
sented in the accompanying Drawing.
In witness whereof, I, the said John Keighley, have hereto set
my hand and seal, this Twenty-second day of August, in the
year of our Lord One thousand eight hundred and seventy-four.
