I WILLIAM BURROW. SHORLAND of Albert Street: Manchester in the County of
Lancaster, Estate Agent, do hereby declare the nature of said invention for
IMPROVEMENTS IN OR APPLICABLE TO LATCHES," to be as follows:-
Ordinary lever latches are actuated by a lifting, movement before the door to
which the latch is applied can be opened the object of my invention is to actuate
lever latches, and open doors or parts to which they are applied by a direct pull or
push applied to a handle, and my invention consists in applying a lever handle
to lever latches under the latch if applied on one side, and over the latch if applied
on the other side of its fulcrum.
The lever is formed to act both as a handle and lever, hinged or jointed to the
door, or frame or plate, of the latch and it is cranked and arranged so that when a
pull is applied to the handle in the direction to open the door or part to which it is
applied the latch will be lifted and the door opened; In some cases I connect with
the lever handle on one side of the door a knob or handle on the other side of the
door, so that the latch is actuated and the door opened by a direct pull on one side
and push on the handle on the other side.

.
According to a modification of my invention I combine a lever to act upon the
latch as above described and joint this lever with one end of a rod or part forming
a handle which at its other end is jointed to a lever corresponding to the lever for.
the latch which is hinged or jointed to the door or latch frame or plate so that when
a pull is applied to this handle the latch is lifted and the door opened.
The two levers or one of them jointed (or connected or in contact) with the above.
described handle on one side of the door are or may be continued to the other side.
of the door so that a push upon the handle on one side and a pull upon it on the
other side of the door will lift the lever latch and open the door..

I, WILLIAM BURROW SHORLAND of Albert Street Manchester in the County of
Lancaster, Estate Agent do hereby declare the nature of my Invention for
IMPROVEMENTS IN OR APPLICABLE TO'LATCHES" and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:—
The present method of operating an ordinary lever latch necessitates two motions
of the hand viz:-a downpressure or a lifting motion by the thumb or forefinger
and a push or pull to open the door or other part to which it is applied.
The object of my invention is to combine these two motions in one, so that the
push upon one side or the pull upon the other side, of the door or other part
nessessary to open it will also raise the latch.
To attain this, I combine the handle and lever in one which is hinged or pivoted
to the door or frame plate of the latch in such a manner that an inclined plane or
crank formed upon the handle will lift the latch upon the handle being pulled
in order to open the door or other part to which it is applied. In this case the lever
handle is pivoted from its extreme end.
For the other side of the door (or other part) I pivot the lever handle from its
crank or bend and fix it so, that the extreme end of the lever rests beneath the
latch, upon the other side of the door (or other part) Upon this handle being
pushed the end of the lever lifts the latch.
Or, I lift the latch from the other side of the door by pushing the first handle
by means of a rod passed through the door.
up
I use either of the above named lever handles seperatley as well as together or in
reversed positions to suit the fulcrum of the latch or I combine them in one so that
a push on one side or a pull upon the other side of the door will open the latch.
In another modification of my invention I use a lever (corresponding to the lever
of the ordinary latch) to connect the lever handle upon one side of the door (or other
part) with the latch."
In order that the foregoing may be better understood I send herewith a sheet of
drawings in which:-Fig.1 shows the simplest form of the apparatus; upon pulling
the handle b the inclined plane g lifts the latch a. Fig 2 shows the two levers
joined in one; in this Figure a push upon the handle c and a pull upon the
handle lifts the latch a. Fig 3 shows the apparatus with a lever a push upon the
handle e raises one end of the lever d the other end of which pushes down
the extreme end of the latch a which being upon the other side of the fulcrum lifts
it as desired. I do not confine myself to this particular ring shape of handle, but
use different patterns.
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
1st A latch in which lever and handle are combined in one so that a direct push
or pull will both raise the latch and open the door or other part to which it is
