PROVISIONAL SPECIFICATION.
Improvements in Hinges.
We, WOLF DEFRIES, of 4 Cleveland Gardens, London, Gentleman, and VICTOR
ISIDORE FEENY, of 7 Queen Victoria Street, London, Consulting Engineer, do
hereby declare the nature of- this invention to be as follows:-
Our invention relates to certain improvements in the construction of hinges for
railway carriage and other doors, whereby the wear is distributed over a much larger
surface than in hinges of ordinary construction, and provision is made for the ready
unhinging of the door.
For this purpose we propose to make the hinge in two parts of precisely similar
shape. Each of these parts or flaps has at its side a boss extending preferably half-
way across the flap vertically, the ends of these bosses where they meet when the
flaps are placed together being a horizontal surface. These bosses are drilled or
bored, through the whole or part of their length, with conical holes, tapering inwards
from the aforesaid horizontal surface, into which is fitted a loose pin tapered corre-
spondingly from its centre to either end. This pin is preferably provided with a
spiral groove extending over its whole length for the purpose of facilitating the
distribution of oil or other lubricating medium over the entire wearing surface of
the hinge. We further provide along the length of each of the bosses one or more
projecting flanges which enter and work in corresponding grooves formed in the
flap immediately opposite. These flanges extend around the boss so far as it is
intended for the hinge to open when in use, and prevent the two parts from
becoming detached unless the hinge is opened to a greater extent, when the flaps are
free and the door may be removed; the operation being facilitated by the double-
tapered pin.
In our hinge the wear being distributed throughout the entire length of the pin
as well as over the horizontal surfaces of the bosses and the flanges, any settle-
ment of the door is very materially delayed and the life of the hinge correspondingly
increased.

We, WOLF DEFRIES, of 4 Cleveland Gardens, London, Gentleman, and, VICTOR

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:-
-
Our invention relates to certain improvements in the construction of hinges for
railway carriage and other doors, whereby the wear is distributed over a much larger
surface than in hinges of ordinary construction, and provision is made for the ready-
unhinging of the door.
· For this purpose we make the hinge in two parts of similar shape. Each of these
parts or flaps has at its side a boss extending preferably half way across the flap
vertically, the ends of these bosses where they meet when the flaps are placed together
being a horizontal surface. These bosses are drilled or bored, through the whole or

page_text: part of their length, with conical holes, tapering inwards from the aforesaid horizontal
surface, into which is fitted a loose pin tapered correspondingly from its centre to
either end. This pin is preferably provided with a spiral groove extending over its
whole length for the purpose of facilitating the distribution of oil or other lubricating
medium over the entire wearing surface of the hinge. We further provide along the
length of each of the bosses one or more projecting flanges which enter and work in
corresponding grooves formed in the flap immediately opposite.
These flanges extend around the boss so far as it is intended for the hinge to open
when in use and prevent the two parts from becoming detached unless the hinge is
opened to a greater extent, when the flaps are free and the door may be removed;
the operation being facilitated by the double-tapered pin.
Upon the accompanying Sheet of Drawing:-
Figure 1 is a front view of a hinge embodying our invention;
Figure 2 a plan of the same; the dotted lines indicating the extent to which the
flap opens when in use;
Figure 3 represents a front view of the hinge showing the two flaps partly
disconnected:
Figure 4 shows the pin detached and
Figure 5 is a vertical section through the boss of the hinge;
Figures 6, 7 and 8 shows a modification in the shape of the bosses at their
meeting point.
Similar letters of reference indicating similar parts in each of the figures
respectively,
A A are the two parts or flaps of the hinge.
BB the bosses; b, 61, recesses in same.
'C the conical pin; c spiral groove in same for passage of oil.
D, D, the projecting flanges; d, d¹, ends of same.
E. E, grooves formed in flaps to receive flange.
Upon reference to Fig. 2 it will be seen that when the flap A¹ is opened to the
position shown therein it will have passed beyond the end d of the flange D
and is therefore free to be lifted as shown Fig. 3, but up to this point the
flaps are securely held together by the retaining flanges D D working in the
grooves E El. The position of the flanges and grooves might be reversed and their
form be modified.
We may for the purpose of keeping dust and dirt from the hinge joint make the
ends of the bosses B B¹ with recesses b. b. so that they may enter each other as
illustrated Figs. 6, 7 and 8 of the drawing.
We may make our improved hinge of any suitable metal or material and of any
shape and dimensions.
In our hinge the wear being distributed throughout the entire length of the
pin as well as over the horizontal surfaces of the bosses and the flanges any settle-
ment of a door is very materially delayed and the life of the hinge correspondingly
increased.
Having now particularly described and ascertained the nature of our said Inven-
tion, and what manner the same is to be performed, we declare that what we
claim is:
1. A hinge having flaps formed to receive a loose double conical pin vertically
means of retaining the flaps in position to turn on said pin and upon each other and
means of separating the two parts or flaps of the hinge when opened to a suitable
angle, the whole arranged and working substantially as described.
2. In a hinge, the use of a double conical pin set loosely in holes of a corre-
sponding shape formed in bosses one on each flap of the hinge substantially as
described.
3. In a hinge having a double conical pin set loosely in a boss on each flap, the
use of a projecting retaining flange or flanges on the boss of one flap working in a
corresponding groove or grooves in the boss of the opposite flap whereby the parts of

page_text: the hinge are kept together but with facility of separation when opened to a certain
extent substantially as described.
4. A hinge constructed, combined and arranged to work substantially as hereinbefore
described and illustrated upon the accompanying sheet of Drawing.
