I BENJAMIN WHITEHEAD of Hope Works Bradford Road Birstall, in the county
of York Master Mechanic do hereby declare the nature of my invention for IMPROVE-
MENTS IN SHEDDING MECHANISM OF LOOMS to be as follows:-
The particular part of the loom to which this invention refers to is the heald
jack lever and hook or blade which are two pieces of metal about 8 in. thick.
One end of the jack lever requires to be connected to the bottom end of the jack
blade, in such a manner as to allow of the two working at right angles with each
other. This invention relates to the mode of making this connection, to facilitate
explanations hereinafter one of the two parts shall be called A and the other part B.
One end of A is formed by the metal of the required thickness and strength coming
round ths (more or less as required) of a circle the remaining 1th or thereabouts
being left open or not encircled by the metal; at the top, or bottom of the
circle, and in about the center of the thickness of the metal is a groove or concave
slot, whilst opposite, although not necessarily directly opposite is a lug or piece of
metal, about the same thickness as the breadth of the slot, and placed in about the
center, of the thickness of the metal, and projecting into the circle, whilst the end
of B which is to be connected to A is a circular end the same thickness as A & of
such a diameter as to just fit and work in the circular space formed in A the circular
end of B is a kind of head connected to B by a continuation of the metal.
On this head there is a lug or piece of metal about the thickness of B & pro-
jecting out from about the center of the thickness of the said head, whilst opposite
although not necessarily directly opposite a groove or concave slot is made in about
the center of the thickness of the metal & the same breadth as the aforesaid groove
in A, a part of one or both sides of the said groove in B is left open.
By placing B behind A and at such an angle as to cause the open space in the
side or sides of the groove in B to be directly behind the lug or projection in A, it
will allow of B being brought forward so that the circular head of B enters the
circular space of A move the two pieces at right angles and the projection of A enters
the groove in B, whilst the projection of B enters the groove in A and thus connects
the two together and allows them to work one in the other.
The angle at which the two are placed to connect or dis-connect them, being a
different angle to what they ever, reach whilst moving in their working positions,
makes it impossible that the two should become disconnected except when required.
Dated this 30th day of November 1888.

I BENJAMIN WHITEHEAD of Hope Works Bradford Road Birstall in the county of
York Master Mechanic do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
The particular part of the loom to which this invention refers is the "heald jack
lever and hook or blade." One end of the jack lever requires to be connected to the
bottom end of the jack blade in such a manner as to allow of the two working at
right angles with each other.
".
This invention relates to the mode of making and working this connection.
Drawings herewith will facilitate explanations.
A is the book or blade. B is a projection the thickness of A and is placed in
the centre of the diameter of A. C is a concave or slot in the centre of A. D is the
end of lever. E is the thickness of D and is the outside third. F is a concave or
slot in the centre of the diameter of D. G is a projection the thickness and in the
centre of D.
Place D behind A at an angle that brings B to E. D can then be brought forward
into the centre of A.
Move the lever D down when B will enter slot F whilst G enters slot C and the
joint becames connected, the position of the projections may be varied somewhat and
another form of connection is shown by H being the hook. I is the thickness of,
and is placed in the centre of the diameter of H. J is the end of lever, the back of
which is solid. K is a groove in and is the depth of J. L is two slots the
thickness of J. and in the centre of its diameter. These slots are open into the groove K
and to the outside of the circular part of J. Place J behind H at an angle of 1 equal
to K, then J can have its circular end brought forward into the circular space of the
hook H. Move the lever J down, then I will pass into L and form the desired con-
nection. The connecting angle being different to the working angle or position
makes it impossible to disconnect them except when required.
I am aware of the Specification of Letters Patent No. 15672 of 1888 granted to
James Ward and John Ward and I wish it to be understood that I do not claim
anything described and claimed therein.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
(1) The construction and arrangements of the parts marked A to L with their
varied applications for forming a joint or connection between the jack levers and
blades employed in the shedding mechanism of looms for weaving or for other purposes.
Dated this Twenty-ninth day of August Eighteen hundred and eighty-nine.
