Improvements in Hinges.
We, JAMES GRIERSON SMITH, Moulder and JOHN THOMAS HINES, Carpenter,
both of Covington, Kenton County, Kentucky, United States of America, do
hereby declare the nature of this invention to be as follows:-
Of the two leaves of the hinge of this invention, the one is formed with a
vertical boss from which there extends a vertical pintle or hinge rod. Adjacent
to the boss and pintle it has also an outwardly projecting inclined way at the inner
or leaf end of which and consequently at the highest point there is a depression
and beyond the depression a recess in the leaf which is fixed to the gate or door
post or shutter by screws. The second leaf of the hinge carries a boss or sleeve
for taking on to the pintle and also a friction roller for rolling up or down the
inclined way of the other leaf according as the door, gate, or shutter is being
opened or shut. When wide open the friction roller passes into the depression on
the inclined way and it may be also into the recess in the opposite leaf so as to be
out of the way, the depression keeping the roller and consequently the door fixed
in the open position and the bottom part of the inclined way keeping it closed.
The two parts of the hinge can only be put together or separated at a given point.
The door is prévented from rising too high on the pintle by a boss on this latter
taking into an eye on the ascending hinge sleeve.
Dated this 17th day of August 1893.

slot or aperture 8 in which is located the antifriction roller 4. Section A has a
slot 9 into which the antifriction roller passes when the hinge is opened outside.
It will be observed that the way 7 inclines so as to raise section B the eye 2 then
sliding upwards on the pintle 3. At the back end of the inclined way there is a
depression a into which roller + drops and holds the hinge in the open position.
In the preferred form shewn in Fig. 5 the forward end of way 7 lies in the
horizontal plane and the way commences to ascend at a distance back sufficient
to allow of the door moving out of the jamb before roller 4 begins to travel up
the incline, thus preventing the hinged object from binding in the case or jamb.
The form of Fig. is adapted for a gate; that of Fig. 3 for a shutter; and
that of Fig. 5 for a door.
In Fig. 3 the way 7 is horizontal with the exception of the depression a. C is
the casing of a window and D the shutter shewn open. When it is closed it is
designed to be held by a lock so that it may not be opened from the outside, hence
only one recess a is provided and that to hold the shutter open.
In order to prevent the hinged object from being raised too high and thrown off
the hinge when opened quickly a lug bis provided on pintle 3 and a slot c through
eye 2, lug being placed sufficiently low so that eye 2 will bear against the lug
and allow section B to turn until the slot C comes opposite the lug when the eye
will pass down into its proper position.
It will be obvious that the antifriction roller and inclined way may be attached
to the leaves of an ordinary butt hinge and be made strong and compact so that
the hinged object may be fully opened, the two leaves abutting one against the
other as in an ordinary butt hinge, and hold the hinged object open or closed as
desired, the incline serving to hold the parts closed and the recess a holding them
open. It is also clear that the pintle 3 might be attached to the leaf B and the
boss 1 pierced to form the journal for the axis.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim, is :-
A butt hinge consisting of the two sections or leaves A, B, the one provided
with the long pintle 3, the inclined way 7 having the recess a at its highest point
and the aperture 9 in said leaf at a point opposite the inclined way, and the other
leaf provided with a long eye 2, engaging the pintle, and with the antifriction
roller 4 adapted to travel on the inclined way and partially enter the recess in the
pintle carrying leaf, substantially as described and shewn.
