IMPROVEMENTS IN THE MANUFACTURE OF FLUSH HANDLE SOCKETS
Year: 1884

page_text: I, SAMUEL CRANMORE of Birmingham in the County of Warwick do hereby
declare the nature of my Invention for "IMPROVEMENTS IN THE MANUFACTURE
OF FLUSH HANDLE SOCKETS" to be as follows, that is to say:-
My invention has for its object improvements in the manufacture of flush handle
sockets by which I am enabled to make them much lighter in regard to the general
strength as a whole and also cheaper than such articles have been made heretofore
on account of the saving in labor.
Hitherto flush handle sockets have been made in two pieces viz the front
portion of cast metal and the back part of sheet brass or other wrought thin metal
which is rivetted or clenched over or otherwise fastened to the back of such cast
metal fronts.
Now according to my invention I take a plate of sheet brass or other soft metal
and having formed suitable moulds or stamp dies with easy inclinations to the
sides and curves I stamp or press these said plates by certain gradual operations
according to the thickness of the plates and the depth of the sockets. At two sides
of the said sockets deep recesses are formed somewhat square at the sides in which
I place the knuckle ends of the handle which are fastened with two pivots passing
through the sides of such recesses and the handles. But before placing the handle
in position I cut a certain amount of the backs of these recesses away to allow the
back or knuckles of the handle to clear the back of the plate. When the ears of
the handle socket found in the deep recess are required stronger than usual I turn
the metal of the bottom of the recesses back to form a double thickness at that
part which answers the purposes admirably and with very little cost in labour.
The back of the plate has its edges turned down all around to imitate a bevelled
edge of solid metal but it has the double object and effect of greatly strengthening
the plate at its edge from buckling, when the sockets are very light.
Though the sockets would be generally made from brass I do not confine myself
to that metal as wrought iron and other soft yielding metals may be used.

page_text: I SAMUEL CRANMORE of No 47 Vyse Street Birmingham in the County of
Warwick do hereby declare the nature of my Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF FLUSH HANDLE SOCKETS "and in what manner the same is
to be performed to be particularly described and ascertained in and by the following
statement that is to say :-
My Invention has for its object improvements in the manufacture of flush handle
sockets by which I am enabled to make them much lighter in regard to the general
strength as a whole and also cheaper than such articles have been made heretofore
on account of the saving of labour.
Hitherto flush handle sockets have been made in two pieces viz the front portion
of cast metal and the back part of sheet brass or other wrought thin metal which
is rivetted or clenched over or otherwise fastened to the back of such cast metal
fronts.
In order that my invention may be clearly understood and more readily carried
into practice, I have appended hereunto a sheet of drawings with the help of which
I will now proceed to explain my invention:-
Now according to my invention I take a plate of sheet brass or other soft metal
and having formed suitable metal moulds or stamps and dies with easy inclinations
to their sides and curves I stamp or press these said plates by certain gradual
operations such for instance as a series of dies leading gradually up to the finished
form required the number of operations of blows being suited to the thickness of
the plate under treatment and the particular form or depth of the socket being
made.
Figure 1 is a front elevation of a flush socket handle made according to my
invention.
Figure 2 is a cross sectional elevation through the centre of the said flush socket
handle.
Figure 3 is a part back elevation of the same with the handle out.
Figure 4 represents a front view of the same kind of flush handle socket slightly
modified in form.
Figure 5 is a cross section and elevation of Figure 4 and
Figure 6 is a view of the back of Figure 5 with the bandle in.
The plate is formed into a deep recess or recesses A as shewn by Figures 1, 4, 2, 5,
into which the handle is hung either by the pivot or pivots B Figures 1 and 2 or
by the pivot C of Figures 45 and 6.
In the case of Figures 1, 2 and 3 I cut away the back part D of the plate so as
to give perfect freedom to the back of the handle and in some cases instead of
cutting this metal out entirely I bend back a piece on each side to make the
ears e, e, e and thicker so as to better hold the pivot which answers the purpose
admirably with very little cost in labour.
The back the plate has its edges k, k, k turned down all round to imitate a
bevelled edge of solid metal, but it has the double object and effect of greatly
strengthening and stiffening the plate at its edge and also keeps it from buckling
when the sockets are very light.
It will be evident that many varieties of shapes may be made in these handles
such for instance as the socket plates for one finger or the socket plates which are
in themselves both sockets and handles.
Though these sockets would be generally made from brass I do not confine
myself to that metal as wrought iron and other soft yielding metal may be used.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed; I declare that what
I claim is
The improvements in the manufacture of flush handle sockets from wrought
metal plates forming the front sides and back of such sockets stamped or pressed
in dies with the pivots formed by either single metal as shown by Figures 4, 5
and 6 or with double metal and separate pivots or pivots B as shown by Figures 1,
2 and 3 and substantially as herein set forth and as shewn upon the drawings.
Dated this 7th day of October 1001.
