page_text: PROVISIONAL SPECIFICATION.
We CHARLES MACKINTOSH of 23 Worthington Street Leicester, Sewing Machine
Agent and WILLIAM MARSDEN RICHARDS of No 1 Millstone Lane Leicester,
Valuer do hereby declare the nature of the said invention for "A HINGE" to
be as follows:-
This hinge is capable of a variety of applications with or without modifications
in its construction, though it is particularly applicable to-the leaves of screens and
the like, as by its use they can be folded with inuch greater freedom than is possible
with the ordinary hinges.
This hinge consists essentially of two plates the ends of which may be rounded.
These plates are connected by one or more links, pivotted at the centres of the
rounded ends of the plates, in such manner that the plates are free to play round
each other with their ends in close proximity. This allows the leaves of a screen
to be placed in line with each other or over lapping, parallel or at any angle to
each other, and they can be brought together so as to exclude draught.
•
The link or links may be placed at either or both sides of the plates or sunk or
recessed into the plates.

page_text: We CHARLES MACKINTOSH 23, Worthington Street Sewing Machine Agent,
and WILLIAM MARSDEN RICHARDS 1; Millstone Lane both in Leicester, Valuer do
hereby declare the nature of this invention for "A HINGE" and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :--
This hinge is capable of a variety of applications with or without modifications
in its construction, though it is particularly applicable to the leaves of screens and
the like, as by its use they can be folded with much greater freedom than is possible
with the ordinary hinges.
This hinge consists essentially of two plates the ends of which may be rounded.
These plates are connected by one or more links, pivotted at the centres of the
rounded ends of the plates, in such manner that the plates are free to play round
each other with their ends in close proximity. This allows the leaves of a screen
to be placed in line with each other or overlapping, parallel or at any angle to
each other, and they can be brought together so as to exclude draught.
The link or links may be placed at either or both sides of the plates or sunk or
recessed into the plates.
The accompanying drawings show this hinge in various positions and with some
slight modification of construction.
A A are the leaves or plates; these are jointed together by the link B which may
be sunk within the thickness of the plate as in Figure 1 or rest upon the plates if
they are not recessed to receive it. Figure 4 shows the same form as in Figure 1
but it is turned the other way up and attached to portions of a screen C Figure 5
is a modification which readily explains itself; the link B works between jambs
and the leaves A are shaped so as to suit this particular application CC are
portions of a screen.
The forms shown in Figures 2, 3, and 7 are similar to an ordinary butt hinge
with the links B inserted. By means of this link B either plate A of the hinge can
be turned round the other, the link C acting as a radius bar to keep the two parts
always the same distance apart.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what
we claim is
In a hinge the link B which unites the two leaves A while allowing greater
freedom of movement than if the two plates were jointed directly together
substantially as specified.
