Year: 1874

page_text: LETTERS PATENT to John Bland, of Keighley, in the County of York,
Machine Maker, for the Invention of "IMPROVEMENTS. IN LOOMS."
COMPLETE SPECIFICATION filed by the said John Bland at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 11th July 1874, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BLAND, of Keighley, in the County of York, Machine Maker, send
greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
Looms," and have petitioned Her Majesty to grant unto me, my exe-
cutors, administrators, and assigns, Her Royal Letters Patent for the
same, and have made solemn Declaration that I am the first and
true Inventor thereof.
.
NOW KNOW YE, that I, the said John Bland, do hereby declare
that, the following Complete Specification, under my hand and scal,
:
:

page_text: Fig. 1 is an end elevation of my improved apparatus as applied to the
ordinary looms for weaving; Fig. 2 is an elevation of the same.
In Fig. 1 A, A, is the ordinary cast-iron framework of loom; B is
the end of ordinary cylindrical warp beam, to which I fix a flanged
collar C, upon which is cast a tappet T2; around this collar is placed
a jointed clip or break D, to which is cast a rod E having bracketed
projection at E 1, and carried down in order to secure clip to framework
of loom at F by bolt G. To the bottom half of clip D is cast a pro-
jection H, through which is passed a bolt J which which terminates as
a shackle K, through which end of lever L is passed, the fulcrum of
lever can be at M or N cast to top part of clip D. To the long end of
lever L is suspended a rod O by means of shackle O¹ terminating in a
hook O which carries shackle P, this shackle is center'd into long
lever L' at C¹, this lever L1 is center'd at C 2 into bracket B1 fixed
to loom end by bolt B 2 on the long end of lever; Ll is a moveable
carriage with several recesses to carry weight W in its required
position. Through a projection or flange Q 2 cast to carriage Qa
.

page_text: screw'd rod $
passes parallel to lever L', the other end of rod S is carried
by boss Q 3 cast to lever L'. To this rod S is keyed a catch wheel R,
and secured by nut R¹. To the rod E forming part of clip D is
cast a bracketed boss E 1, in which a balanced lever L 2, is center'd
at C3; on one end of 12 is a weight W1 to keep tappet end of
lever T against tappet T₂, to lever L2 is cast a lever L' at right angles
in order to carry catch C4 center'd-C 5, or in other centres provided to
suit the required motion ofcatch C 4 when working into catch wheel R.
All other parts of the ordinary loom not necessary for the elucidation
of these improvements are omitted in the Drawings, being the same in
any ordinary loom to which my improvements may be applied.
ACTION OF THE APPARATUS.
Motion is imparted to the warp beam in the ordinary way, cach
revolution of the beam tappet T2 on collar C presses down T of
lever L2, and concequently the catch wheel R is moved round any
number of teeth required, from one to six, by means of catch C4,
wheel R being fast to screwed rod S; it will be readily understood that
the carriage Q sliding on L' will be carried forward in the direction of
the catch wheel R, and thus relieve the break D of proportionate grip,
thus regulating the supply of the whole warp to the loom with uniform
regularity and tension and without the intervention or care of the weaver.
In witness whereof, I, the said John Bland, have hereunto set
my hand and seal, this Second day of July, in the year of our
Lord One thousand eight hundred and seventy-four.
Signed, sealed, and delivered by
the above-named John Bland in
the
presence of
JOHN WAUGH,
Engineer & Patent Agent,
Bradford.
