Improvements in Hinges.
I, THOMAS RYLAND, of Hope Cottage, Carlton Grove, Brixton, in the County
of Surrey, Mechanic, do hereby declare the nature of this invention to be as
follows:-
The invention has for its object improvements in hinges whereby, when required,
one leaf of a hinge can be adjusted in height in relation to the other leaf..
For this purpose instead of using a fixed hinge pin, I employ a pin which is
adjustable in height in relation to one leaf of the hinge and which, as heretofore in
some classes of hinges, bears at its lower end on the bottom of a socket formed in
the knuckle of the other leaf of the hinge.
In carrying my invention into effect in that class of hinge having a single knuckle
to each leaf, and in which one leaf is readily removable from the other, I form the
knuckle of one leaf, (that is to say, the bottom knuckle,) with a socket closed at
the bottom to receive the hinge pin, which latter, at its bottom end, rests on the
bottom of the socket and carries the weight of the door, gate, &c., to which the
other leaf is attached.
The parts above referred to are common to many forms of hinges and separately
form no part of my present invention. Instead however of fixing the hinge pin in
its carrying knuckle (or upper knuckle) of the other leaf as heretofore, I, according
to my present invention, adjustably fix the pin in said knuckle by forming a screw
thread in the socket of the knuckle and a corresponding screw thread on the upper
part of the hinge pin, the upper or outer end of which latter is made suitable to be
turned either by a screw driver or key as may be desired. I also preferably place
on the screwed part of the hinge pin, a lock nut, by which the said hinge pin, when
adjusted in height in its knuckle, can be readily set fast therein. It will be readily
understood that the leaves and knuckles of the hinge may be reversed in position.
Thus if a door, gate, &c., should be found to have dropped, it can be readily raised
to its proper position by adjusting the hinge pin in its screw knuckle.
In applying my invention to a hinge in which one leaf cannot be removed from
the other without previously removing the hinge pin, I will illustrate the same as
applied to a hinge in which one leaf has a knuckle which is placed between the two
knuckles or parts of knuckles of the other leaf. In this case I form the space
between the two knuckles or parts of knuckles of the one leaf, greater than the
length of the knuckle of the other leaf, and I form such central knuckle with a
screw threaded socket to receive the screw formed on the hinge pin, which latter is
plain at its upper end and also at its lower end to fit plain sockets formed in the
two outer knuckles, one of such sockets being closed at its lower or outer end to
receive the end of the hinge pin.
Thus the hinge.pin is capable of adjustment in height in relation to its screwed
socket, and the central knuckle is thereby capable of adjustment in height within
the space between the two knuckles or divided knuckle of the other leaf.
It will be evident that the hinge last above described may be reversed in
position, and that my invention is applicable to hinges having other numbers of
knuckles.

Improvements in Hinges..
I, THOMAS RYLAND, of Hope Cottage, Carlton Grove, Brixton, in the County
of Surrey, Mechanic, 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 :-
The invention has for its object improvements in hinges whereby, when required,
one leaf of a hinge can be adjusted in height in relation to the other leaf.
My invention is illustrated in the accompanying drawings, in which :-
Fig. 1 is a face view and Fig. 2 is a plan or edge view of a hinge each leaf of
which carries half of the knuckle and the leaves of which are readily separable from
each other.
Fig. 3 is a vertical section through the knuckle.
Fig. 4 is a face view with the knuckle in section and showing one leaf raised in
relation to the other, and
Fig. 5 is a view of the hinge pin separately.
Fig. 6 is a face view with the knuckle in section showing my invention applied to
a hinge in which the leaves cannot be separated from each other except by first
removing the hinge pin.
In all the figures like parts are indicated by similar letters of reference.
According to my invention, instead of using a fixed hinged pin, I employ a pin
which is adjustable in height in relation to one leaf of the hinge and which, as
heretofore in some classes of hinges, bears at its lower end on the bottom of a socket
formed in the knuckle of the other leaf of the hinge.
In carrying my invention into effect in that class of hinge having a single
knuckle to each leaf and in which one leaf is readily removable from the other, as
represented in Figs. 1 to 5, I form the knuckle a' of one leaf a, (that is to say, the
bottom knuckle), with a socket closed at the bottom to receive the hinge pin c,
which latter, at its bottom end, rests on the bottom of the socket and carries the
weight of the door, gate, &c., to which the other leaf b is attached.
The parts above referred to, with the exception of the adjustability of the leaf b
carrying the hinge pin, which I am now about to describe, are common to many
forms of hinges and separately form no part of my present invention. Instead
however of rigidly fixing the hinge pin c in its carrying knuckle 6 of the leaf bas
heretofore, I, according to my present invention, adjustably fix the pin c in said.
knuckle b' by forming a screw thread in the socket of the knuckle 6' and a corre-
sponding screw thread c on the upper part of the hinge pin, the upper or outer
end of which latter is made suitable to be turned either by a screw driver or key
as may be desired. I also preferably place on the screwed part cl of the hinge pin
a lock nut d by which the said hinge pin c when adjusted in height in its knuckle b¹
can be readily set fast therein.
In Figs. 1 and 2 the knuckle 6' is shown in contact with the knuckle a', but in
Fig. 4 the knuckle 6' and its leaf 6 are shown raised in relation to knuckle a¹
and leaf a.
I will now describe the hinge represented at Figs. 6 and 7 in which one leaf
cannot be removed from the other without previously removing the hinge pin.
These figures represent a hinge in which the leaf b has a knuckle b¹ which is placed
between the two knuckles or parts of knuckles a' of the other leaf a.
In this case
I form the space between the two knuckles or parts of knuckles a¹ of the leaf a
greater than the length of the knuckle b' of the other leaf b, and I form such
central knuckle with a screw threaded socket to receive the screw c¹ formed on
the hinge pin c, which latter is plain at its upper end c³ and also at its lower end c
to fit plain sockets formed in the two outer knuckles a¹ a¹*, the socket a¹ being
closed at its lower or outer end to receive the end of the hinge pin c.

page_text: By the constructions herein shown and described, the hinge pin c is capable of
adjustment in height in relation to its screwed socket and the central knuckle b' is
thereby capable of adjustment in height within the space between the two knuckles
or divided knuckles a¹ a¹ of the leaf a.
It will be evident that the hinges herein shown and described may be reversed
in position and that my invention is applicable to hinges having other numbers of
knuckles or divided knuckles.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. The improved hinge having one leaf adjustable in height in relation to the
other leaf, substantially as herein shown and described.
2. The improved hinge having one leaf adjustable in height in relation to the
other leaf by the combination of an adjustable hinge pin having a screwed portion
screwing into a knuckle of one leaf and a plain part or parts lodged in a plain
socket or sockets in the knuckle or knuckles of the other leaf and bearing on the
end of the supporting socket, substantially as herein shown and described.
3. The improved hinge having one leaf adjustable in height in relation to the
other leaf by the combination of an adjustable hinge pin screwed into a knuckle of
one leaf and resting in a plain socket in the knuckle of the other leaf and a lock
nut to fix the hinge pin in position, substantially as herein shown and described.
