IMPROVEMENTS IN HINGES FOR RAILWAY AND OTHER CARRIAGE DOORS, AND OTHER ANALAGOUS PURPOSES to be as follows:
Year: 1884

I, WILLIAM WILKES of Mill Lane Works Bloxwich in the county of Stafford,
Railway carriage Lock Manufacturer do hereby declare the nature of my invention
for "IMPROVEMENTS IN HINGES FOR RAILWAY AND OTHER CARRIAGE DOORS, AND
OTHER ANALAGOUS PURPOSES to be as follows:-
"
My improvements consist in the construction of Lubricating hinges both single
and double jointed. In constructing the one with single joint, I employ a steel
pin having a double-conical shoulder in about the middle of it, the one end of
which with its half-double cone shoulder is driven into the upper leaf or flap of
the hinge, whilst the other end with its half-double cone thereon fits into and
turns in a corresponding hole formed in the bottom leaf or flap of the hinge.
The object I have in forming the double conical shoulder on the aforesaid steel
pin, is first, that of strengthening it, and secondly, that of taking the wear off those
parts of the hinge which meet together in the joint. This pin I slightly flatten
upon the shoulder and bottoni end only.
In the upper part of the joint or knucle of the bottom leaf or flap; I drill a hole
slantwise into the recess in which the conical shoulder turns. This hole forms a
resevoir for the reception of oil which can only be inserted when the hinge is
open, and by virtue of the shoulder and bottom end of the pin being slightly
flattened the oil decends and lubricates the hinge.
In order to prevent the two leaves or flaps of the hinge from coming assunder
I preferably cut a groove in the lower end of the pin with conical shoulder thereon,
and screw a pin through the joint or knucle which projects into the groove before
mentioned and thereby secures the two halves from separation.
In constructing a double jointed hinge, the single joint or knucle of the one leaf
or flap of the hinge which fits into and works between the two joints or knucles
at either end of the other leaf or flap, I drill only part of the way on either side,
thereby leaving a solid space in the middle, but in this case I employ two steel
pins instead of one as in the former case, only that these pins are ordinary plain
pins slightly flattened on one side as herein before mentioned, and having conical
points corresponding with the conical bottoms of the holes formed by the point of
the drill,

page_text: These two pins are driven from either end of the joints or knucles of one leaf
or flap of the hinge, slightly projecting at each end, and the non-working end of
ench being held firmly in position by virtue of its being driven into a smaller hole
than that which the other end works in.
The pin in the upper joint or knucle having a conical point has the same effect.
of taking off the wear of those parts of the hinge which meet together at the joint.
Upon the projecting ends of the aforesaid pins 1 st two caps which I secure to
the ends of the leaves or flaps of the hinge by means of soldering them thereto or
other suitable means.
The method of lubricating in this case is precisely the same as in the former,
only that the pin in the top joint or knucle is lubricated from one side, whilst
that of the bottom is lubricated from the other side.
On the single jointed hinge I also claim forming a solid ornamental cap at either
end.
What I particularly claim as my invention is the special construction of
Lubricating hinges for railway and other carriage doors, and other analagous
purposes as herein before mentioned.
I do not however strictly confine myself to the exact details herein described as
the same may be variously modified.

page_text: I, WILLIAM WILKES of Mill Lane Works Bloxwich in the county of Stafford,
Railway carriage lock Manufacturer, do hereby declare the nature of my invention
for "IMPROVEMENTS IN HINGES FOR RAILWAY AND OTHER CARRIAGE DOORS, AND
OTHER ANALAGOUS PURPOSES" and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
My improvements consist in the construction of Lubricating Hinges both single
and double jointed. In constucting the one with single joint, I employ a steel
pin, A, Fig. 1. having a double conical shoulder in about the middle of it, the one
end of which with its half-double cone shoulder is driven into the upper leaf or
flap, B, of the hinge, whilst the other end with its half-double cone thereon fits
into and turns in a corresponding hole formed in the bottom leaf or flap, C, of the
hinge. h. h. are solid caps.
The object I have in forming the double-conical shoulder on the aforesaid steel
pin, A. is first, that of strengthening it, and secondly, that of taking the wear off
those parts of the hinge which meet together in the joint.
This pin I slightly flatten upon one side of the shoulder and bottom end only.
In the upper part of the joint or knucle, D. of the bottom leaf or flap, C, I drill
a hole, E, slantwise into the recess in which the conical shoulder turns. This hole
forms a resevoir for the reception of oil which can only be inserted when the
hinge is open, and by virtue of the shoulder and bottom end of the pin being
slightly flattened on that side nearest the hole, E, which forms the reservoir when
the hinge is open the oil descends and lubricates the joint of the hinge. In order
to prevent the two leaves or flaps of the hinge from coming assunder, I preferably
cut a groove, f. in the lower end of the pin with conical shouder thereon, and
screw a pin, g. through the joint or knucle which projects into the groove
before mentioned and thereby secures the two halves from separation. h. h are
solid caps.
In constructing a double jointed hinge, Fig. 2, the single joint or knucle of the
one leaf or flap, a, of the hinge which fits into and works between the two joints
or knucles at either end of the other leaf or flap, b, I drill only part of the way
on either side, c, c. thereby leaving a solid space, d, in the middle, but in this case
I employ two steel pins instead of one as in the former case, only that these pins
are ordinary plain pins slightly flattened on one side as herein before mentioned,
and having conical points corresponding with the conical bottoms of the holes
formed by the point of the drill as shewn in drawing. These two pins are driven
from either end of the joints or knucles of one leaf or flap of the hinge, slightly
projecting at each end, and the nou-working end, e. e. of each being held firmly in
position by virtue of its being driven into a smaller hole than that which the other
end works in. The pin in the upper joint or knucle having a conical point has
the same effect of taking off the wear of those parts of the binge which meet
together at the joint. Upon the projecting ends of the aforesaid pins I fit two
caps which I secure to the ends of the leaf or flap, b, of the hinge by means of
soldering them thereto or other suitable means, The method of lubricating in this
case is precisely the same as in the former with the exception of the top and
bottom pins being lubricated on either side, g. g.
Fig. 3, shews a concealed hinge for private and other carriages. H, is the plate
of the same, I, is the reservoir, J, is a solid angular piece projecting from the back
of the plate to the pillar, K, through which I drill a hole slantwise into the hole
through which the screw, L, passes, down which hole the oil descends and
lubricates the screw and joint of the hinge as in the former case.

page_text: The same method applies to the lubricating of butt hinges only that in this case
I preferably drill a hole slantwise through the face or front of the joint or knucle
when the hinge is open as shewn at. M. Fig. 4.
Having now particularly described and ascertained the nature of my invention,
and in what manner the same is to be performed, I declare that what I claim is
1-The improved construction of single and double jointed hinges with
lubricating devices, substantially as hereinbefore described and illustrated
in figures 1 and 2 of the drawings.
2-The improved methods of lubricating the pins of binges substantially as
herein-before described
