IMPROVEMENTS IN THE MANUFACTURE OF TURNBUTTONS AND PLATES FOR FASTENING OF DOORS AND WINDOWS
Year: 1884

page_text: I, JOSEPH WALKER, of 13 & 14 Augusta Street Birmingham, in the County
of Warwick, Diesinker do hereby declare the nature of my invention for
IMPROVEMENTS IN THE MANUFACTURE OF TURNBUTTONS AND PLATES FOR
FASTENING OF DOORS AND WINDOWS to be as follows:-
Instead of casting the Turnbuttons and plates in the usual manner I make dies
of the exact size and pattern of the parts required and stamp and press the parts of
the Turnbuttons and plates out of sheet metal. I then with ordinary press tools
cut the surplus metal away from the outer edges and by a further process I pierce
the holes for the screws and also the centre hole in the button to receive a pin or
rivet upon which the button revolves, I then for the purpose of supporting the
button and to make it firm insert in the button a piece of cast iron or other metal,
with a hole in the centre through which the pin or rivet passes. The three parts
being thus prepared, I then pass the pin or rivet through the hole in the Turn-
button and through the block of metal inside the button and afterwards through
the centre hole in the plate; I then fasten or rivet it underneath the plate leaving
it sufficiently loose for the button to revolve upon the plate in the usual manner.
By the method I have now described, I can obtain a clearer and more dense
surface than by casting, and by using cominon or cheaper metal for the separate
supporting block inside the button the cost of producing is reduced.
claim the making of Turnbuttons and plates from rolled sheet metal by
stamping or pressing the same into dies, the shape and size of the said dies
corresponding with the shape and size of button and plate required.

of Warwick Diesinker do hereby declare the nature of my invention for
IMPROVEMENTS IN THE MANUFACTURE OF METALLIC TURNBUTTONS AND PLATES
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
Instead of casting the turnbuttons and plates in the usual manner, I make dies
of the exact size and pattern of the parts required, and stamp and press the parts
of the turnbuttons and plates out of sheet metal. I then with ordinary press tools
cut the surplus metal away from the outer edges and, by a further process I pierce
the holes for the screws and also the centre hole in the button to receive a pin or 1
rivet upon which the button revolves.
I, then, for the purpose of supporting the button and to make it firm, insert in
the button a piece of cast iron or other metal, with a hole in the centre, through
which the pin or rivet passes. The three parts being thus prepared, I then pass
the pin or rivet through the hole in the turnbutton, and through the block
of metal inside the button and afterwards through the centre hole in the plate;
I then fasten or rivet it underneath the plate, leaving it sufficiently loose for the
button to revolve upon the plate in the usual manner. By the method I have now
described I can obtain a clearer and more dense surface, than by casting, and by
using common or cheaper metal for the separate supporting block inside the button,
the cost of producing is reduced.
Having now particularly described and ascertained the nature of my said
declare that what
Invention, and in what manner the same is to be performed,
I claim is
First, the making of turnbuttons and plates from rolled sheet metal by stamping
or pressing the same into dies, the shape and size of the said dies corresponding
with the shape and size of button and plate required.
Secondly, I claim the making of turnbuttons and plates as herein before
described, tho said turnbuttons each having a supporting block of iron or other
common metal, inserted underneath and within the said hollow turnbuttons for the
purpose of supporting and giving firmness to the said turubuttons,
