Improvements in Hinges.
I, FRANZ SPENGLER, of No. 6, Alte Jakobstrasse, Berlin, in the Empire of Germany,
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 a hinge with a vertical axis, which is distinguished by
the arrangement between the two parts which bear against one another when the
hinge is operated, of special renewable slide pieces, which rub one against the other,
and thus prevent the wear of the most important parts of the hinge.
In the accompanying drawing,
Figure 1 shows an elevation of the improved hinge.
Figures 2, 3 and 4 show details of the renewable slide pieces and
Figure 5 shows another form of renewable slide piece.
In the door-hinge shown in Figure 1 I arrange between the two sockets a and b
of the hinge plates c and d on the pine of the former, two slide rings ƒ and g which
bear one upon another and which are attached to their respective parts a and b of
the hinge in such a manner as not to rotate thereon. The securing of these rings f
and y to the parts a and b, which may be done in various ways, is effected in the
present case, for example, by tongues or projections h, one of which is placed either
on the hinge pin a or b, and the other on the rings for g, and which takes into a
corresponding notch i. By this means the surfaces of the rings ƒ and g must bear
against one another in the movement of the hinge, and consequently preserve the
main parts of the hinge from wear.
In the arrangement shown in Figure 5, in which the hinge is intended as a base
hinge for doors or such like, the slide-pieces k and do not bear against one another
over their whole surface, but are so arranged that a conical projection, connected
with the slide piece k by means of a pin m or such like, turns in a corresponding,
conical cavity n of the piece l. The pieces k and l, one of which is connected with
the vertical axle e, the other with a base plate o by means of a pin or such like, can
be renewed, as likewise can the conical projection, by means of which the main
parts of the hinge are entirely protected from wear.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. A hinge with vertical pin, characterized by the arrangement between the two
parts of the hinge turning against one another of two metal pieces, each of which
is connected to its part of the hinge so as not to be rotatable thereon in such a
manner that in the movement of the hinge they bear against one another and
consequently protect the main parts of the hinge from wear.
2. A hinge as set forth in Claim 1, characterized by having the two pieces (fand g)
made in the form of rings, which rings are laid on the pin (e) and are connected
with their respective hinge pieces (a and b) by tongues or projections (h).

of solid metals which likewise are connected with their respective hinge-pieces so as
not to be rotatable thereon (Figure 5).
