PROVISIONAL SPECIFICATION.
Improvements in Butt and other Hinges, and in the Manufacture of
the same.
We ROBERT WOOTTON of 113 Harborne Road Edgbaston Gentleman and
FRANCIS HENRY GRIFFITHS of 74 Trafalgar Road Handsworth Engineer both in
Birmingham County of Warwick do hereby declare the nature of our said invention
to be as follows:-
Our invention has for its object improvements in butt and other hinges & in the
manufacture of the same by which such hinges are made of steel and consequently
have much more strength without increasing the cost of manufacture as it enables
us to utilize scraps of metal produced in the course of manufacture.
In carrying our invention into effect we take a length of tube of the length of
the hinge required and this be flatten down with the exception of the one side in
which we insert a mandril of the size of the pin after which we slot out the side
in any convenient manner so as to form the one half of the butt. We also form the
other half of the hinge in a similar manner but slot it out to fit the projections
upon the other half of the hinge and it is obvious that the sides may be slotted to
form any number of projections & recesses as may be required for the joint by
reason of the length of the hinge. The two halves are then jointed together by
the insertion of the pins which may be rivetted in position.
Our improvements are particularly suited to long hinges such as those for
pianoforte lids or other such purposes and we may bronze or nickle them as may
be required. Each half having the double thickness of drawn steel are free from
the liability to break as is the case with the cast butts.

COMPLETE SPECIFICATION.
Improvements in Butt and other Hinges, and in the Manufacture of
the same.
We, ROBERT WOOTTON, of 113 Harborne Road, Edgbaston, Gentleman, and
FRANCIS HENRY GRIFFITHS, of 74 Trafalgar Road, Handsworth, Engineer, both
in Birmingham, County of Warwick, do hereby declare the nature of our said
invention & in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
Our invention has for its object improvements in butt and other hinges and in
the manufacture of the same by which such hinges are made of steel and
consequently have much more strength without increasing the cost of manufacture
as it enables us to utilize scraps of metal produced in the course of manufacture.
In carrying our invention into effect we take a length of tube of the length
of the hinge required and this we flatten down with the exception of the one side
in which we insert a mandrel of the size of the pin after which we slot out the side

page_text: in any convenient manner so as to form the one half of the butt. We also form
the other half of the hinge in a similar manner but slot it out to fit the projections
upon the other balf of the hinge & it is obvious that the sides may be slotted to
form any number of projections and recesses as may he required for the joint by
reason of the length of the hinge. The two halves are then jointed together by
the insertion of the pins which may be rivetted in position.
Our improvements are particularly suited to long hinges such as those for
pianoforte lids or other such purposes and we may bronze or nickle them as may
be required. Each half having the double thickness of drawn steel are free from
the liability to break as is the case with the cast butts.
In order that our invention may be clearly understood & more easily carried into
practise we have appended hereunto a double sized sheet of drawings upon which
we have fully illustrated the nature of our said improvements and the mode of
carrying the same into effect.
Figure 1, is an end elevation of a piece of scrap of tube from which we form the
parts of the hinge.
Figure 2, is an elevation of Figure 1.
Figure 3, is an elevation showing the tube after undergoing the first process.
Figure 4, is an end elevation of Figure 3.
Figure 5, is a similar elevation to Figure 3 but after undergoing a further
process;
Figure 6, is a similar elevation to Figure 5 of the reverse half of the butt.
Figure 7, is an elevation of the butt complete shown open.
Figure 8, is a cross section through Figure 7.
Figure 9, is an end elevation showing the butt when closed.
Figure 10, is an elevation of a hinge suitable for pianoforte lids & other such
purposes.
We form the hinge from a length or scrap of tube such as A Figures 1 and 2
which we stamp press or otherwise flatten down into the form shown by Figure 3
a mandrel being inserted so as to form the socket at a for the pin of the butt.
We then slot the bulged side at a as shown by Figure 4 so as to form the one half
of the butt, the other half being manufactured in exactly the same way except that
the other side A' is slotted at a so as to leave the projecting sockets at a which
fit the socket piece a'. The screw holes a are then punched or otherwise formed in
the flaps of the butt and the two halves A and A' are secured together by the
pin B which may be rivetted in position or the centre socket a³ may be pressed
down so as to fix the pin firmly in position.
These hinges may be formed from tubes of steel brass or any other suitable
metal and are particularly suited for long hinges such as used for pianoforte lids
or other such purposes and are particularly free from any liability to break as in
the case of cast butts.
Having now particularly described and ascertained the nature of our said inven
tion & in what manner the same is to be performed we declare that what we
claim is
The improvements in butt and other hinges and in the manufacture of the same
substantially as and for the purpose herein set forth and shown upon the accom
panying drawings.
