ROBERT C. MORRIS, OF OLNEY, ILLINOIS, ASSIGNOR OF ONE-HALF OF HIS
RIGHT TO HIRAM H. McL ANE, OF SAN ANTONIO, TEXAS.
IMPROVEMENT IN ANGLE-PLATES FOR DOORS.
Specification forming part of Letters Patent No. 220,4890 dated October 1.4, 1879; application filed
August 1, 1878.To all whom it may concern:
Be it known that I, ROBERT C. MORRIS, of
Olney, in the county of Richland and State
of Illinois, have invented certain new and
useful Improvements in Doors; and I do here-
by declare that the following is a full, clear,
and exact description of the invention, which
will enable others skilled in the art to which
it appertains to make and use the same, ref-
erence being had to the accompanying draw-
ings, and toletters ofreference marked thereon,
which form a part of this specification-
Figure 1 being an elevation of a portion of
a door, a section thereof being broken away
to show the application of my improvement;
and Fig. 2 is a perspective view of the strength-
ening-bracket.
Corresponding letters denote like parts in
both of the figures.
This invention relates'to doors and gates
generally, it being particularly applicable to
such as are hung upon hinges, the object be-
ing to provide against sagging, and otherwise
to strengthen them so that they shall not be
liable to change their form.
The improvement consists in inserting into
the corner or corners of doors or gates a me.
tallic bracket or brace, which is so arranged
therein as to give firmness to the structure,
and prevent it from sagging when upon hinges
or changing its form when otherwise applied.
In providing doors or gates with my im-
provement, I prefer to cut in one or more cor-
ners thereof a groove for the reception of a
web or brace, A, formed upon the bracket A',
as shown in Fig. 1 of the drawings.
The bracket A' is substantially of the form
shown in Fig. 2, thevertical and horizontalpor-
tions thereof being at a right angle to each
other, and each provided with apertures for
the reception of screws with which to attach
them to the door, said horizontal portion be-
ing of sufficient length to cause it to pass be-
yond the joint between the side and end rails
of the door.
Extending from the vertical to the horizon-
tal portions there is a web or brace, which, as
above stated, is let into a slot formed in thedevice for its reception, said web or bracepre-
venting the bending of the bracket, and thus
any sagging of the door when mounted upon
its hinges.
This bracket may be made of any suitable
kind of material, such as cast-iron, wrought-
iron, malleable iron, or brass, and in cross-
section the vertical, and horizontal portions
may be of such width as to be equal to the
thickness of the door to which it is applied;
or they may be of less width, and in being ap-
plied be let into a recess formed for their recep-
tion in the door.
In the drawings accompanying this specifi-
cation I have shown but one bracket, and that
as applied to the lower outer corner of the
door; but I contemplate using two or more in
each door, according as the dimensions and
weight thereof may require, and I also pro-
pose to use them in the upper or lower cor-
ners, or both, as occasion may demand.
It is apparent that this improvement is ap-
plicable to sliding doors as well as to those
which swing upon hinges. It is also applica-
ble to gates, window-shutters, and other simi-
lar structures, and especially to the doors of
railroad-cars, which, owing to their violent
usage, are often found out of form, and are
thus prevented from moving upon their roll-
ers or hangings. In the latter class of doors
it will probably be found advisable to insert
a bracket in each of its corners, by doing
which the change of form above alluded to
will be entirely prevented.
It should be remarked that the vertical and
horizontal portions of the brackets may be of
any desired length and of varying thickness,
according to the service required of them.
Having thus described my invention, what
I claim, and desire to secure by Letters Pat-
ent, is-
A strengthening-bracket for doors, gates,
or frames generally, to be applied to the ex-
ternal angles of the same, consisting of a
strip or plate of metal bent or formed to the
desired angle, one of the legs of said angle-
piece being of sufficient length to cover and
embrace the joint of the meeting parts of the
