IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR ACTUATING THE CATCHES OF DOOR LOCKS OR FASTENERS
Year: 1884

page_text: I JOSEPH KAYE of Bank Works, Kirkstall in the County of York, Lock Maker
do hereby declare the nature of my Invention for IMPROVEMENTS IN THE METHOD
OF AND APPARATUS FOR ACTUATING THE CATCHES OF DOOR LOCKS OR FASTENERS
to be as follows:-
:
This invention relates to certain improvements in the method of and apparatus
for actuating the catches of door locks or fasteners, and consists in an arrangement
whereby the catch is operated by pushing only at either side of the door.
Letters Patent were granted to Joseph Kaye, Jim Wainwright Kaye, and Walter
Kelita Kaye, dated 22nd of December A.D. 1877 for the construction of a latch or
fastener wherein a lever worked by the push or pull of a spindle or knob moves
in one direction only a segment or finger turning on a fulcrum and pressed in the
opposite direction by a spring so as to engage with a catch plate.
My present improvements relate to the method of actuating the lever à in
Figure 1 in the said specification and the lever L in Figures 1. 8. and 12 of the
specification of Letters Patent granted to me on the 14th of February A.D 1883
and numbered 814.
To the door on one side I fix a handle firmly through the middle of which a
hole is bored for a spindle to pass through. This spindle is cut to the proper
length in order to operate the lever h or L in the above named specifications, of the
lock or fastener: on to this spindle I put a cap of metal for the finger or thumb to
press against. On to the other side of the door but secured to the lock, I have a
similar handle as above described; but the spindle of the one operates upon the
lever which actuates the catch at one end whilst the other operates upon the lever
between the fulcrum and the catch or fastener.

page_text: ·I, JOSEPH KAYE of Bank Works, Kirkstall, in the County of York, Lock
Maker, do hereby declare the nature of my invention for IMPROVEMENTS IN THE
METHOD OF AND APPARATUS FOR ACTUATING THE CATCHES OF DOOR LOCKS OR
FASTENERS, 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 certain improvements in the method of and apparatus
for actuating the catches-of-door-locks-or-fasteners, and consists in an arrangement
whereby the catch is operated by pushing only at either side of the door.
Letters Patent were granted to Joseph Kaye, Jim Wainwright Kaye, and Walter
Kelita Kaye, dated 22nd of December A.D). 1877 for the construction of a latch or
fastener, wherein a lever worked by the push or pull of a spindle or knob, moves
in one direction only a segment or finger turning on a fulcrum, and pressed in the
opposite direction by a spring so as to engage with a catch plate.
My present improvements relate to the method of actuating the lever h in
Figure 1 in the said specification; and the lover Lin Figures 1, 8, and 12 of the
specification of Letters Patent granted to me on the 14th of February A.D. 1883,
and numbered 814.
In order that my invention may be more completely understood, reference is
made to the accompanying drawings which are marked with letters and figures of
reference, and in which Fig 1 represents an elevation of a lock made with my
improved apparatus for actuating the catches applied thereto, the cover plate of the
lock being removed. Fig. 2 represents a sectional plan through line a b., and a
section through a portion of the door and striking plate frame.
To the door A on one side I fix a handlo B by the screws C, and through the
middle of the said handle a hole is bored for the spindle D to pass through; in this
spindle is bored another hole for the reception of a smaller spindle D¹ which is cut
to the proper length in order to operate the lever ; which is effected by pressing
the thumb or finger against the end of the said spindle D, thereby. actuating the
lever h, causing it to ride on its fulcrum at h¹, and the opposite end of lever at h²,
to act upon the arm of the finger, catch, or fastener G, and the latter to withdraw
itself from the striking plate H, thus liberating the door.
On the other side of the door, but secured to the lock, is a similar handle B¹,
through which a spindle D2 is passed, and which operates on the opposite side of
the lever h, thereby actuating the catch or fastener G, when the spindle D' is
pressed inwards by the thumb or finger, thereby liberating the door; and as soon
as the pressure of the thumb or finger is. removed from the spindles D or D2, the
catch or fastener G is moved back to its original position by spring S, which is
compressed between the said catch or fastener G, and projection P.

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 construction of a door lock or fastener wherein the lever h is worked from
either side of the door by the pushing of a spindle by which the fastener or catch G
is withdrawn from the striking plate, all arranged substantially as herein described
and illustrated by Figs 1 and 2 of the accompanying drawings.
