SAMUEL THOMAS ONIONS Hinge Maker 56 Dudley Road Wolverhampton in the
County of Stafford, do hereby declare the nature of this invention to be as follows:-
A machine for making from cold metallic plates joint hinges known in the trade as
butts, flaps, chest, bed, and tee hinges, and the like, and by so doing obviate the
present mode of forging the same from hot metals.

COMPLETE SPECIFICATION.
Improvements in Appliances for Making Metallic Hinges from
Cold Metals.
SAMUEL THOMAS ONIONS Hinge Maker, 56 Dudley Road, Wolverhampton, in the
County of Stafford, 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 :—
Improvements in appliances for making metallic hinges, known in the trade as
butts, flaps, chest, bed, and tee hinges, and the like, from cold metals, and by so
doing obviate the present mode of forging the same from hot metals.
The accompanying drawing filed with the Provisional Specification shews:-
Fig. 1 Front end view of closing machine.
Fig. 2 Sectional view of the machine shewing the lever in horizontal position
for receiving the metal plate (the plate is shewn as being in the machine).
Fig. 3-Back end view.
Fig. 4 Plan of the bed of the machine.
Fig: 5 & 6 Metal platos cut with slots-or burrs-of more or less number to be
placed in a stamp or press for forming into the desired shape as shewn A A
figure 9.
Figs. 7 & 8-Tools used in a stamp or press by which the metal plate (5 or 6),
is formed into a shape as shewn A. A. fig. 9.
Fig. 10 Sectional view of machine shewing the plate in position in the machine
ready for closing by the lever.
Fig. 11-Shews the lever raised to a vertical position, which action closes the plate
as shewn at A. in this figure.
In carrying out the Invention, I take a metal plate cut with the necessary
slots or burrs-and place it in a stamp or press in which has been inserted tools
shewn in figures 7 & 8 of the accompanying drawing, the action of the stamp or
press is to form the plate into a shape marked A. A. fig. 9. which forms the first
[Price 6d.]

page_text: flap. I then place the plate in the machine in the position shewn in fig. 10; a
mandril (worked automatically), passes through the groove formed in the plate, then
the lever of the machine is lifted by mechanical or other means to the position shewn
in fig. 11, whereby the plate is closed, and the second flap formed, and the hinge
joint completed.
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
The closing of cold metallic plates for the formation of a hinge joint by an
appliance known as a lever, shewn in the drawing accompanying the provisional
specification moved by mechanical or other power.
