Improvements in Hinges.
I, CHARLES HAMMON DAVIS, of the Town of Gloucester, in the County of
Athens, State of Ohio, one of the United States of America, Carpenter 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:-
a
My invention relates to certain new and useful improvements in hinges, the
object being to provide a novel form of hinge, the pintle of which may be readily
removed while a door is hung thereon, whereby should the lock of the door stick
and fail to unlock, the said door may be opened without removing the hinge or
breaking the lock.
Having this object in view, my invention consists in certain novel constructions,
combinations and arrangements of parts, as will be hereinafter more fully described
and claimed.
In the accompanying drawing:
Figure 1 is a side elevation view of the hinge.
Figure 2 is a section view of the same through the knuckles and pintle.
Figure 3 is a detail view showing the parts of the hinge disconnected.
Referring to the drawing, the letters A, B, designate the two leaves of the
hinge. The leaf A, is adapted to be secured to the joint of the door and the other
leaf B, to the door. The said jamb-leaf is provided at one end with a knuckle c, c¹,
with an open space between them. The door leaf has a single central knuckle d,
to occupy said opening.
The leaves are pivotally connected by a removable pintle E, which passes
through the knuckles c, d, but does not extend entirely through the knuckles c¹.
The pintle has a knob or head e, which rests upon the knuckle c. A plug, also
has a head f, in imitation of the pintle head and a body fitting from below with
the space in the knuckle c', left vacant by the pintle. Its sole purpose is to give
to the hinge the appearance of having a pintle passing entirely therethrough and
having two heads."
Considerable difficulty is often experienced in opening doors having mortised
locks, which frequently become stuck so that the door cannot be opened without
breaking the lock or taking off the hinge. By removing the pintle E, my hinge
the door may readily be released and opened.
My invention provides a simple and cheap hinge which entirely overcomes the
objections stated.
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. A hinge provided with a pintle fitted loosely therein, whereby the leaves may
be separated by simply pulling out the pin, substantially as described.
.
2. A hinge having two leaves formed with engaging knuckles, and a pin fitting
loosely in said knuckles, whereby it may be readily removed, substantially as
described.
3. The combination with a door-jamb and door, of a binge having two leaves
counecting said jamb and door and provided with engaging knuckles, a false piutle

fitting loosely in said knuckles, substantially as described.
