Improvements in Compound Hinges, particularly applicable for
Casements and Doors.
I, GARIBALDI HERBERT, of 9, Princes Road, Tivoli, Cheltenham, Draughtsman,
do hereby declare the nature of this invention to be as follows:-
According to this invention, I construct compound hinges to do the work
of two pairs of butt hinges. And in order that my said invention may be clearly
understood, I will proceed to describe the same with reference to the drawings
accompanying this specification, in which Fig. 1 shews a sectional plan of the
hanging stile of a casement, connected to the casement frame by means of one
of the aforesaid compound hinges, and Fig. 2 shews the elevation of such a hinge.
The same letters of reference are employed to denote the same parts in all the
views. S shews the casement, C, the hanging jamb of casement frame, e, el, a, b, d,
compound hinge, h screw face plate, g screwfastening, f centre bit hole to allow
the head of the said screw fastening to go into the jamb, H hole in plate a, to
allow screwfastening to pass into the face plate h, so as to fasten plate a of the
hinge to the stile of the casement. When it is required to pass the casement
through the frame for cleaning, the fastening is taken out. The dotted lines A
on the drawing indicate the position of the casement when opened outwards, and
those at B, its position when opened inwards. The hinges are so constructed that
the centres of all the knuckles are practically in the same vertical plane as the
inner face of the plate a The hinges are so fixed in relation to the stile of case-
ment, and the jamb of its frame, that the knuckles e are half in the stile of case-
ment, and half in the jamb, and the knuckles e¹ are not let into the jamb and
are kept clear of the outer face of the hanging stile of casement. The marks x
between the dotted lines on plates d & a indicate the portions where they have
to be eased so as to allow the said plates to fold together in the position shewn
on the plan. It should be understood that on the elevation of the hinge Fig. 2,
the easements are on the farther side; also that the plates are eased where
strength is the least required. By the use of hinges as described and shewn on
the drawing, casements or doors can be swung inwards or outwards without
having recourse to the method shewn in Figs. 2 & 3 Sheet 2, of those drawings
filed with my Provisional Application No. 15,664 (1898) where I use two pairs
of butt hinges.

Casements and Doors.
I, GARIBALDI HERBERT, of 9, Princes Road, Tivoli; Cheltenham, Draughtsman,
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 follow-
ing statement:-
According to this invention, I construct compound hinges with the centres of
their knuckles practically in the same vertical plane as the inner face of the
centre plate of the hinges, and without shaping the butts of the inner knuckles
to the rabbet projection of the window or door frame. By this means either a
door or casement may be swung inwards without interference with the usual
rabbets.
And in order that my said invention may be clearly understood, I will now
proceed to describe the same with reference to the provisional" drawings, in
which
Fig. 1 shews a sectional plan of the hanging stile of casement, connected to
the case frame by means of the aforesaid compound hinges, and Fig. 2 shews
the elevation of compound hinges.
The same letters of reference are employed to denote the same parts in both
figs. C, shews the hanging jamb of casement frame, S the hanging stile of case-
ment, a shews the centre plate of compound hinge b leaves of hinges fixed to
casement, d leaves of hinges fixed to casement frame, e inner knuckles, e¹ outer
knuckles, thumbscrew face plate let into stile of casement, thumbscrew which
fixes hinge to casement by passing through the hole H into the aforesaid thumb-
screw face-plate, f centre-bit hole to receive head of thumb screw.
The dotted line A shews the casement opened outwards, and at B opened
inwards.
The plate a extends between the upper and lower hinges.
The marks x indicate where the front of the leaves d, and the back of the
plate a, are bevelled out, so that when the casement is in its closed position the
parts come together as shewn on plan.
The leaves bare sunk into the casement so that half of the knuckles e, go into
the casement and half into the jamb, while the circumference of the said knuckles
are flush with the face of casement. The outer knuckles e¹ are not let into the
jamb. By placing the leaves d at the back of the plate a, while the planes of
their faces pass through the centres of the knuckles e', the plate a is allowed to
turn round the said knuckles far enough to allow the closing stile of casement to
pass through the frame.
If the hinges should be made in pressed metal it would be better to make the
knuckles e continuous. It is not absolutely necessary that the plate a should be
extended between the top and bottom hinges, as the said top & bottom hinges
could be screwed on a strip of oak let into the rabbet of the jamb. of casement
frame, similar to that shown in Figs. 2 & and 3. Sheet 2 of those drawings accom-
panying my Application No. 15664, 1898.
I wish it to be understood that I make no claim for joining the top & bottom
parts of compound hinges together, by extending the centre plate of such hinges
between the said parts.
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:-
1st. That construction of the hinges that place the centres of all the knuckles

page_text: in the same plane as the face of the centre plate a, as herein-before described
and shown on plan at a, e, e¹, Fig. 1 of the "provisional" drawings.
2nd. That construction of the hinges that place the leaves d in such a position
that the back of the centre plate, closes against the faces of the said leaves, while
the plane of their faces pass through the centres of knuckles e¹, as herein before
described, and shown on plan at, a, d, e, Fig. 1, of the "provisional" drawings.
3rd. That construction of compound hinges (for reversible casements and the
like whose jambs have rabbet-projections) that makes it necessary to secure the
centre-plate of such hinges to the hanging stile of casement when such casement
is in ordinary use, as shown by the dotted lines at A Fig. 1 of the "provisional'
drawings.
"
4th. That construction of compound hinges (for reversible casements and the
like whose jambs have rabbet-projections) that place the inner knuckles in the
angle of the jamb and the circumference of the said knuckles flush with the face
of casement, as shown at e Fig. 1 of the "provisional" drawings.
