the County of York, and James Harrop Buckley, of London, in the County of
Middlesex, for the Invention of " AN IMPROVED JOINT FOR CONNECTING THE
JACK-HOOKS AND LEVERS EMPLOYED IN LOOMS FOR WEAVING."
PROVISIONAL SPECIFICATION left by the said James Hollingworth and
James Harrop Buckley at the Office of the Commissioners of Patents on the
3rd July 1879.
JAMES HOLLINGWORTH, of Dobcross, near Huddersfield, in the County of York,
and JAMES HARROP BUCKLEY, of London, in the County of Middlesex.
"AN
IMPROVED JOINT FOR CONNECTING THE JACK-HOOKS AND LEVERS EMPLOYED IN
LOOMS FOR WEAVING."
In the accompanying Drawing we have illustrated our improved joint, which is
constructed by forming one of the parts, say the part marked A, with a rounded
end B having a central stud C and a small projection a, opposite to which is a clip
or hook b. The other part marked D is formed with a larger end É countersunk
within the dotted line F to receive the end B of the other portion. A hole d is
also provided to receive the stud C. The outer portion G is slotted from e to f, and
a small piece is cut out of one of the sides of the slot g. The edge H is formed
about one fourth the thickness of the part G. In putting the parts together the
clip bis placed on the edge H at about H', and the stud c and projection a passed
through the openings d and g. If the parts are then turned so as to form about a
right angle with each other they cannot be separated, the projection a within the
slot e, f, and the clip b on the edge H holding them together laterally, but allowing
the parts to turn or vary their angle to the extent of about 80 degrees, or nearly a
quarter of a revolution.

JAMES HOLLINGWORTH, of Dobcross, near Huddersfield, in the County of York,
and JAMES HARROP BUCKLEY, of London, in the County of Middlesex.
IMPROVED JOINT FOR CONNECTING THE JACK-HOOKS AND LEVERS EMPLOYED IN
LOOMS FOR WEAVING."
This Invention relates to the construction of the jack-hooks and levers employed
in looms for weaving, whereby we obtain an improved form of joint when the two
parts are placed together, our object being to dispense with rivets or screws and
retain as much strength as possible without increase of weight or trouble in
casting.
In the accompanying Drawings we have illustrated the method we adopt for
dispensing with rivets. Fig. 1 shews the two parts as they appear when joined
together, and Figs. 2 and 3 shew the parts as they appear when separate. It will
be seen that we construct one part, shewn in Fig. 3 and indicated by the letter A,
with a rounded end B having a 'central stud C and a small projection a, opposite to
which is a clip or hook b. The other part, marked D and shewn separately in
Fig. 2, is formed with a large end E countersunk within the dotted line F to receive
the end B of the other portion. A hole d is also provided to receive the stud C.
The outer portion G is slotted from e to f, and a small piece is cut out of one of the
sides of the slot at g. The edge H is formed about one fourth the thickness of the
part G.
In putting the parts together the clip b is placed on the edge H at about H', and
the stud C and projection a passed through the openings d and g. If the parts are
then turned so as to form about a right angle with each other, as in Fig. 1, they
cannot be separated, the projection a within the slot e, f, and the clip b on the
edge H holding them together laterally, but allowing the parts to turn or vary
their angle to the extent of about 80 degrees, or nearly a quarter of a revolution.
Having thus described the nature and particulars of our Invention, and shewn
by Drawings how the same is to be performed, we would have it understood that
we claim as our Invention,-
--
The construction and arrangements of the parts for forming a hinge joint for the
purpose substantially as described and illustrated.
In witness whereof, I, the said James Hollingworth, for and on behalf of
myself and the said James Harrop Buckley, have hereunto set my hand and
seal, this Twenty-second day of December, in the year of our Lord One
-thousand-eight-hundred and seventy-nine.
