Improvements in Hinges.
I JOHN HOWARD CARTLAND, of Constitution Hill, in the City of Birmingham
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction and arrangement of
hinges primarily intended for what are known as parliament hinges, such as are
used for window shutters, but which may be used for other similar purposes.
By reason of the window casements being set back or recessed from the outer
face of the wall, in such hinges the joint of the hinge is extended soine distance
from that part where attachment is made to the window casement and to the
shutter itself, in order, that when the shutters are opened and thrown back, they
shall lie back against the said outer face of the wall.
Usually where such hinges are used it is difficult by reason of inaccessibility to
provide for the securing of such shutters in their opened or thrown back position.
It is the object of this my invention to obviate this difficulty and to provide
ready means whereby such hinges (and thereby the shutters &c. to which they are
secured) may be secured in their said opened position, and in some cases in certain
intermediate positions.
This my invention admits of considerable variation in detail without departing
from its nature.
I provide in conjunction with the joint of such hinges a locking device,
consisting of a sliding pin or bolt, vertical or horizontal, upon the one part of
the hinge taking into a hole or holes, notch or notches upon the other part
of the hinge.
Upon the one part of the hinge is provided a segmental concentric lug about the
joint. In this lug is a hole or notch. In some cases the upper surface of this lug
is inclined. Upon the other part of the hinge and above the said lug, is a boss or
bosses, through which slides loosely a vertical pin, whose lower end is made to fall
into the aforesaid hole or notch in the lug upon the other part of the hinge.
Thus as the hinge is opened the vertical locking pin rides up the inclined surface
of the opposite lug, until at a given position it comes over the hole or notch, when
it falls automatically thereinto and secures the hinge in such position. This position
may as before intimated, be either when the hinge is full or part way open, or
similar notches or holes for both positions.
In some cases I may modify this by making upon the one part an enlargement
of the aforesaid lug, in the shape of a circular arm having therein a number of
holes or notches and by providing upon the other part of the hinge a hole through
which such arm may work. Also upon this last named arm is a suitable guide to
receive the vertical locking pin as before. In either of such or similar cases, the
locking pin may if desired, be supported in its elevated position so as to be free of
the holes or notches named. In some other cases I may provide that the said locking
pin shall be of a bolt form, a guide way for the bolt being provided upon both
parts of the hinge, the said bolt being carried upon the one part, until the hinge is
opened to a given extent when it may be slid into the slide way upon the other
part. Or, a jointed lever, the front end of a lever may be made to engage with
such notches.
Such locking device may be situated at the middle of the depth of the hinge or
at the upper side as may be most convenient.

Improvements in Hinges.
I JOHN HOWARD CARTLAND, of Constitution Hill, in the City of Birmingham
Manufacturer 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 following statement :-
This invention relates to improvements in the construction and arrangement of
hinges, primarily intended for what are known as parliament hinges, such as are
used for window shutters but which may be used for other similar purposes.
By reason of the window casements being set back or recessed from the outer
face of the wall, in such hinges the joint of the hinge is extended some distance
from that part where attachment is made to the window casement and to the
shutter itself, in order, that when the shutters are opened and thrown back, they will
lie back against the said outer face of the wall.
Usually where such hinges are used it is difficult by reason of inaccessibility
to provide for the securing of such shutters in their opened or thrown back
position.
It is the object of this my invention to obviate this difficulty and to provide
ready means whereby such hinges (and thereby the shutters &c. to which they are
secured) may be secured in their opened position, and in some cases in certain
intermediate positions.
This my invention admits of considerable variation in detail without departing
from its nature.
I provide in conjunction with the joint of such hinges a locking device,
consisting of a sliding pin or bolt, vertical or horizontal, upon the one part of
the hinge taking into a hole or holes, notch or notches upon the other part
of the hinge.
In order to more fully explain this my invention I have appended hereunto
an illustrative sheet of drawings, upon which are figures and numbers of
reference, similar numbers referring throughout the several views to the same
thing or part.
Fig. 1, is a rear view of a partly closed hinge made according to this my
invention.
Fig. 2, is a plan view of Fig. 1.
Fig. 3, is a rear view of the hinge full open and locked.
Fig. 4, is a plan view of the locked hinge.
Fig. 5, is a rear view of a modified form of locking device showing the hinge
full open.
Fig. 6, is a plan view of the hinge as shown in Fig. 5.
Fig. 7, is a plan view of this hinge as seen when partly closed.
Fig. 8, is a view in elevation of the hinge as shown in Fig. 7.
Fig. 9, shows a further modification in the method of locking the hinge.
Fig. 10, is a sectional elevation of Fig. 9 on line A-B.
Fig. 11, is a sectional plan of Fig. 9, on line C-D.
Fig. 12 is a rear elevation of a further modification of the manner in which the
hinge may be locked.
Fig. 13, is a plan view of Fig. 12.
In reference to Figs. 1, to 4, inclusive:-I provide upon the part 1, of the hinge,
a segmental concentric lug 2, about the joint 3. In this lug is a hole or notch 4.
In some cases the upper surface of this lug is inclined at 5. Upon the other
part 6, of the hinge and above the said lug 2, are bosses 7, 7", through which slides
loosely a vertical pin 8, whose lower end is made to fall into the aforesaid hole 4,
in the lug 2, upon the other part 1, of the hinge. Thus as the hinge is opened, the
vertical locking pin 8, rides up the inclined surface 5, of the opposite lug 2, until at

page_text: a given position it comes over the hole 4, when it falls automatically thereinto and
secures the hinge in such position, as seen in Figs. 3, & 4. This position
may as before intimated, be either when the hinge is full or part way open, or
similar notches or holes for both positions, by increasing the number of holes 4,
in the lug 2.
In reference to Figs. 5, to 8, inclusive-In this case I have modified this, by
making upon the part 1, an enlargement of the aforesaid lug, in the shape of a
circular arm 2, having therein a number of holes or notches 4, and by providing
upon the other part 6, of the hinge, a hole 9, through which such arm may work.
Also upon this last named part 6, is a suitable guide 7, to receive the vertical
locking pin 8, as before. In either of such or similar cases, the locking pin may,
if desired, be supported in its elevated position so as to be free of the holes or
notches named. To effect this, a smaller pin 10, may be screwed into the pin 8*,
capable of movement up the slot 11, and be turned around the part 11", and thus
support it in its raised position. As will be readily seen, the hinge may be locked
in full open or part open positions, by reason of the holes 4.
In reference to modification illustrated in Figs. 9, 10, & 11, I have made the
locking pin slide horizontally in the form of a bolt 8b, which works in guide or
groove 7, formed upon the part 1°. A similar guide or groove is formed at 13,
upon the part 6, into which the bolt 8b, may slide when the hinge is full open, as
seen in dotted lines in Fig. 11, and thereby lock it in such position.
In some cases, instead of a sliding locking pin, a lever may be used, as shown in
the modification illustrated in Figs 12, & 13. The hinge parts 1° & 6°, and the
arm 2, are similar to those illustrated in Figs. 5, 6, 7, & 8, except that instead of
the holes 4*, notches 4b, are used, into which the lower end of the lever 14, enters.
This lever is pivoted at 15, and is provided with push down piece 16. Upon
pressing down the latter, the lever is drawn clear of the notches and the hinge is
free to open or close, while the hinge is locked at any position in which the lever
is engaged with either of the said notches.
Such locking device may be situated at the middle of the depth of the hinge or
at the upper side as may be most convenient.
Having now particularly described and ascertained the nature of this my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The employment in combination with hinges, of a locking device substantially
as herein described and set forth.
2. In hinges the combination with the part 1, having the lug 2, with the hole 4,
of the other part 6, having the locking pin 8, carried thereon, as described and
shown in Figs. 1, to 4, inclusive.
3. In hinges the modified combination of the part 1", having the arm 2ª, with the
part 6, having the locking pin 8ª, as herein described and illustrated in Figs. 5, to 8,
inclusive.
4. In hinges the modified combination of the part 1', having the sliding bolt 8",
with the part 6, having the bolt groove 13, into which the bolt 8b, may enter, as
described and shown in Figs. 9, 10, & 11.
5. In hinges the modified combination of the part 1°, having the arm 2º, and
notches 4, with the part 6, having the lever 14, which engages with such notches
as described and shown in Figs. 12, & 13.
