Mortise Fastenings.
We, SAMUEL HILL, Cabinet Bar Fitter, of 260 New John Street West, and
ROWLAND HODGES, Brassfounder, of 12 Frederick Street, both in the City of
Birmingham, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in mortise fastenings, our object being to
construct a convenient and effective fastening of few and simple parts that can be
readily attached to the required door.
In the application of our invention to the construction of a mortise fastening for
a show case, a pedestal, or other receptacle, we employ a lever catch having a
circular boss which is mounted within the sides of a metallic case formed preferably
from one strip of brass or other metal. The metallic case completely encloses the
catch lever and as the extremities of the boss are arranged flush with the outer
surfaces of its sides, the complete case with the contained catch lever can be
readily inserted within an aperture or mortise formed in the front edge of the door
stile. A square or other suitably shaped hole is formed through the boss of the
catch lever to receive the end of the handle which is secured to the face plate
attached to front side of the door stile; the operating end of the handle is made
of any required shape or configuration.
When the handle is turned in the direction for fastening, the catch is turned
within its bearings until the projecting arm is caused to enter within a hole or
mortise formed in the framing immediately opposite to the mortise in the door
stile, and the door is thus fastened. On turning the handle in the opposito
direction the lever is withdrawn into its case and the door is thus unfastened.
With double doors the fastening is secured to the stile of one door and the catch
enters within a hole or mortise formed in the stile of the opposite door.
Instead of employing a lever catch having one end of the operating handle
inserted within the same as bereinbefore described, we sometimes construct our
fastening with a lever catch operated by a slotted cam plate or like part in which
the inner end of the handle is inserted. Upon turning the handle the cam plate
partakes of its movement and the catch is thus forced into the door frame mortise
or withdrawn from the same as required, but when fastened the catch cannot be
forced back into its casing until the operating handle is turned in the direction for
nfastening.
We sometimes employ locking mechanism in connection with our improved
fastening, and we make such modifications in the arrangement of the parts within
he metallic case as may be necessary to suit the particular door to which the
astening is to be applied.

We, SAMUEL HILL, Cabinet Bar Fitter, of 260 New John Street West, and
ROWLAND HODGES, Brass Founder, of 12 Frederick Street, both in the City of
Birmingham, 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 improvements in mortise fastenings, our object being to
construct a convenient and effective fastening of few and simple parts that can be
readily attached to the required door.
In the accompanying sheet of explanatory drawings to be hereinafter referred
to ;-
Figure 1 is an end elevation representing one form of our improved fastening
attached to a door, and Figure 2 a front elevation of such fastening, with its
handle and a portion of the door removed.
Figure 3 is a sectional plan representing the fastening in its closed position.
Figure 4 is a front elevation of a modified form of our fastening with the front
or cover plate removed. Figure 5 is an end view of such fastening.
The same reference letters in the different views indicate the same parts.
In the application of our invention to the construction of a mortise fastening for
a show case, a pedestal or other receptacle, we employ a lever catch such as A
Figures 1, 2, and 3 having a circular boss which is mounted within the sides of a
metallic case B formed preferably from one strip of brass or other metal. The
metallic case completely encloses the catch lever A. and as the extremities of the
boss are arranged flush with the outer surfaces of its sides, the complete case with
the contained catch lever can be readily inserted within an aperture or mortise
formed in the front edge of the door stile. A square or other suitably shaped hole
is formed through the boss of the catch lever to receive the stem of the handle C
which is secured to the. face plate D attached to front side of the door stile; the
operating end of the handle C is made of any required shape or configuration.
We sometimes dispense with the metallic case B and mount the catch lever A
directly upon the stem of the handle C, by first placing it in position within the
aperture or mortise formed in the front edge B¹ of the door stile, and afterwards
passing the stem of the handle C through a small hole formed in the face B2 of
the stile and thence into the square eye of the catch lever within the mortise.
When the handle C is turned in the direction for fastening, the catch is turned
with it and thus moved from the position shown at Figures 1 and 2 and caused to
enter within a hole or mortise formed in the framing immediately opposite to the
mortise in the door stile, as shown at Figure 3, and the door is thus fastened. On
turning the handle in the opposite direction the lever is withdrawn into its case, as
shown at Figures 1 and 2, and the door is thus unfastened. With double doors
the fastening is secured to the stile of one door and the catch enters within a hole
or mortise formed in the stile of the opposite door.
Instead of employing a lever catch such as hereinbefore described, we sometimes
construct our fastening of a form.such as A' Figure 4 operated by a lever A2 in
which the inner end of the handle is inserted. Upon turning the handle the
fastening A partakes of its movement and the catch is thus forced into the door
frame mortise or withdrawn from the same as required, but when fastened the
catch cannot be forced back into its casing until the operating handle is turned in
the direction for unfastening. The spring E retains the catch A' in position within
its casing until it is forcibly moved out by the operation of the handle in the
required direction.

page_text: We sometimes employ locking mechanism in connection with our improved
fastening, and we make such modifications in the arrangement of the parts within
the metallic case as may be necessary to suit the particular door to which the
fastening is to be applied.
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 ;-
1. The improved construction and fixing of a mortise fastening comprising an
independent catch lever such as A, with or without an enclosing metallic case,
inserted in the mortise through the opening on the front edge B¹ of the door stile,
and the handle C having a stem which is passed through a small hole formed in
the face B of the stile and thence into the eye of the catch lever, substantially as
described and as illustrated
2. The general combination and arrangement of parts forming the improved
mortise fastenings, substantially as described and as illustrated.
