1, JAMES HODGES of Pool Street Wolverhampton in the County of Stafford,
Lock Manufacturer, do hereby declare the nature of my said invention for
"IMPROVEMENTS IN MORTICE AND RIM LOOKS " to be as follows:-
My invention consists in an improved action on the latch bolt of the above
mentioned locks, whereby I obtain a push and pull motion of the knobs, in lieu of
turning them in the ordinary way to draw in the latch bolt.
At the extreme bottom end of the lock and in or about the centre of the same I
employ a piece of metal, in the centre of which there is a round hole, having a female
screw thread therein for the reception of a spindle having a corresponding screw
thread thereon-On either side of this hole there is another round hole which slide
up and down upon two upright pins in the case of the lock.
Immediately above this, and moving on two other pins across the lock case, I
employ a plate of metal having upon its under side a projecting incline plane,
corresponding with an incline plane upon the piece sliding up and down upon the
other two pins.
This plate of metal has a round hole in the head of the same which fits on a stud
upon a lever which is geared to the latch bolt.
The action of the same is as follows:-
The spindle being screwed into the before mentioned plate, and being either pulled
on one side or pushed on the other, causes it to slide up the pins, and by virtue of the
same, the incline plane thereon pressing and bearing against the corresponding plano
on the plate of metal immediately above it, causes the same to move across the lock,
and in doing so the hole in the head of the same fitting upon the stud in the lever
which is geared to the latch bolt draws the same within the case of the lock, but so
soon as the knob is released, the said plate which is actuated by a spring on the
end of it, moves back to its original position, and in doing so pulls down the
piece of metal with spindle therein and the knobs assume their former position.

Lock Manufacturer, 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 :-
My invention consists in an improved action on the latch bolt of the above!
mentioned locks, whereby I obtain a push and pull motion of the knobs, in lieu of
turning them in the ordinary way to draw in the latch bolt.
At the extreme bottom end of the lock-Fig. 1-and in or about the centre of the
same I employ a piece of metal-a-in the centre of which there is a round hole-b-
having a female screw thread therein for the reception of a spindle having a
corresponding screw thread thereon-On either sido of this hole there is another
round hole- -which slide upon and down upon two upright pins in the case of
Immediately above this and moving upon two other pins-d-d-across the lock
case I employ a plate of metal-e-having upon its under side a projecting incline
plane-Fig. 4-corresponding with an incline plane upon the piece-a-sliding
up and down upon the other two pins.
the lock.
This plate of metal has a round hole-g-in the head of the same which fits upon a
stud upon a lever-h-which is geared to the latch bolt―i.
The action of the same is as follows:-
:-
The spindle being screwed into the before mentioned plate-a-and being either
pulled on one side or pushed on the other cause it to slide up the pins, and by virtue
of the same, the incline plane therein pressing and bearing against the corresponding
plane on the plate of metal immediately above it causes the same to move across the
lock, and in doing so the hole in the head of the same fitting upon the stud in the
lever which is geared to the latch bolt draws the same within the case of the lock,
but so soon as the knob is released this said plate which is actuated by a spring-j-
on the end of it moves back to its original position, and in doing so pulls down
the piece of metal with spindle therein and the knobs assume their former
position.

page_text: 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
The withdrawing of the latch bolt of Mortice and Rim locks by pulling or pushing
together two incline planes substantially as described and illustrated by the
accompanying drawings.
