page_text: I, REUBEN THOMAS PRESTON, of the Firm of J Stone & Company, of Deptford,
in the County of Kent, Engineers, do hereby declare the nature of this invention.
to be as follows.-
My invention relates to improvements in hinges for doors and the like an i
particularly for doors which are exposed to the elements such as railway carriage
doois and the doo18 of other vehicles.
Hitherto great difhculty has been experienced with the hinges of railway and
other carage doors owing to the difficulty of removing the pin which is generally
usted and jammed when it has been in use for some time When from one
icason or another it has become necessary to remove the door it is often impossible
to detach it from the carriage except by the removal of the entue hinge either
from the door itself or from the carriage.
Now according to my invention I provide a hinge the pinhole of which is
slightly tapered from the top to the bottom and a pin which 16 conespondingly
tapered to hit it that is to say it is sufficiently tapered to be capable of holding in
the two parts of the hinge on one of them when tapped in from above by means
of a hammer and yet it may almost as easily be loosened by striking its lower
projecting end when it is necessary to remove it
If desired the pin may be
removably fixed in the hinge by means of a nut or a small lynch pin or a set
Sciew or a split ng or the like and further the pin may have a groove near its
upper or lower end or near the middle into which the set sciew may take. Or the
pin itself
may at its lower end be split for a little distance up, the lower part of
the hinge being made taper in the opposite direction to the taper on the hinge
pin, so that when the latter is in position the split parts expand and prevent the
pin fiom working out if from any reason it should become loosened It is not
however essential that the lower part of the hinge should be made taper in the
contiary duection if the pin be made slightly longer
A further improvement consists in providing the hinge pin with a square for a
epanner or a hole for a tommy so as to allow of giving the pin a part of a turu
or revolution occasionally so as to equalize the wear thereof

COMPLETE SPECIFICATION

page_text: and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement.―
My invention relates to improvements in hinges for doors and the like and
particularly for doors which are exposed to the elements such as railway carriage
doors and the doors of other vehicles
Hitherto great difficulty has been experienced with the hinges of railway and
other carriage doors owing to the difficulty of removing the pin which is generally
usted and jammed when it has been in use for some time When from one
leason or another it has become necessary to remove the door it 18 often impossible
to detach it from the carriage except by the removal of the entire hinge either
from the door itself or from the carriage.
Now according to my invention I provide a hinge with a pin which is slightly
tapered more or less, that is to say it is sufficiently tapered to be capable of holding
in position in the two parts of the hinge and the pin hole in the hinge is corre-
spondingly tapered. The pin need not necessarily be tapered its entire length but
the tapered part must be such as to be capable of holding in one part of the
binge at least for if it be loose in both it will be liable to jump or work out The
pin may either be held in the hinge by being tapped in from above and held by
fiction or it may be held by a nut or other suitable fastening.
Figure 1 of the accompanying drawings represents partly in elevation and
partly in section a hinge constructed according to my invention
Figures 2, 3, 4, and ō are similar views of modifications and
Figure 18 an elevation of another modification
As shewn in Figure 1 I provide a hinge a with a pin hole which is slightly
tapered from the top to the bottom and a pin b which 18 tapered to correspond
with the said pinhole, that is to say the pin is sufficiently tapered to be capable
of holding in the hinge when tapped in from above by means of a hammer and
yet it may almost as easily be loosened by striking its lower projecting end when
it is necessary to remove it
If desired the pin b may be removably fixed in the hinge a by means of a
nut cas shewn in Figure 2 or by a small lynch pin d as shewn in Figure 3 or
by a set screw on a split ring on the like Further the pin b may have a groove e
as shewn in Figure 4 near its lower end into which a set screw f may take or the
groove may be near the upper end of the pin or near the middle if preferred.
As shown in Figure 5 the pin 6 1s at its lower end split at q for a little distance
up, the lower part of the hinge being made taper in the opposite direction to the
tape on the hinge pin, so that when the latter 18 in position the split parts
expand or are forced apart and thus prevent the pin from working out if from
any reason it should become loosened It is not however essential that the lower
part of the hinge should be made tape in the contrary duection if the pin be
made slightly longer
A further improvement consists as shewn in Figure 6 in providing the hinge
pin b with a square h for a spanner or a hole for a tommy so as to allow of giving
the pin a part of a turn or revolution occasionally so as to equalize the wear thereof
and a min of this construction is either as shewn or is provided with the additional
fastenings described and shewn in Figures 2, 3, 4 and 5.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same 18 to be performed, I declare that
what I claim is:-
I A hinge provided with a pin all or part of which is slightly taper sub-
stantially as set forth
2 A hinge provided with a pin all or part of which 18 slightly taper and
additional means for retaining said pin in the hinge substantially as described
and shewn in Figures 2, 3, 4 and 5
3 A hinge provided with a slightly tapered pin and a square or a hole on or in
said pin substantially as described and shewn in Figure 6.

page_text: 4. A hinge provided with a slightly tapered pin, a square or a hole on or in
zaid pin and additional means for retaining the pin in the hinge substantially
as set forth.
