Knobs and to the Fastening of the same.
We, JOHN WILLIAM KERSHAW of 7, Burleigh Road South, Everton, in the County
of Lancaster, Clerk, and SAMUEL BENNETT Gloucester Place, Liverpool, in the
County of Lancaster, Joiner, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide an improved fastening for firmly securing
door handles or knobs to their spindles or rods, so that they cannot work loose, as the
screws now generally used, often do, and so that the handle may be casily removed
when required.
In carrying out the invention, the handle is provided with a sliding or guided spring
catch which engages with teeth cut on the spindle or rod and holds the handle in place.
The spindle is preferably made square, and the teeth preferably in the form of a
ratchet cut on one or more of its sides. number of teeth may be provided, so that the
handle can be secured in any desired position. The catch is made so that it is held in
engagement with the teeth by means of a spring, but if pressed from the outside of
the handle, is moved clear of the teeth, and the handle may then be removed. The
teeth and catch are preferably so formed that the handle can easily be put on to the
spindle in the required position, but cannot be removed therefrom without disengaging
the catch.
In my experimental handle the sliding catch is made flat, having a hole in its
centre rather larger than the spindle, through which the spindle passes. One side of
the catch is provided with a spring, so that the side of the hole nearest the spring is
held in engagement with the teeth on the spindle. The other end of the catch pro-
trudes froin the surface of the handle, and when pressed, will compress the spring and
slide out of engagement with the teeth, so that the handle may be removed. If
desired, however, the catch may be made flush with the handle, so as to be invisible
from the outside. It can then be depressed by a penknife or other suitable instrument.
The catch is held in place by a plate placed over its surface at the end of the handle
nearest the lock, and secured by rivets or screws. These rivets may conveniently form
guides for the sliding catch.

Improvements in and Appertaining to Door or Gate Handles or
Knobs and to the Fastening of the same.
We, JOHN WILLIAM KERSHAW of 7 Burleigh Road South, Everton, in the County
of Lancaster, Clerk, and SAMUEL BENNETT Gloucester Place, Liverpool, in the County
of Lancaster, Joiner, 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 :-
The object of this invention is to provide an improved fastening for firmly securing
door handles or knobs to their spindles or rods so that they cannot work loose, as
the screws now generally used often do, and so that the handle may be easily removed
when required.
The manner in which we carry out our invention may be understood by reference 1
to the accompanying drawings in which :-
Fig. 1 is an elevation, partly in section, of a pair of ordinary door knobs & spindle
fitted with a fastening device in accordance with our invention.
Fig. 2 is a transverse section on line a. fig. 1.
Fig. 3 is a similar view to fig. 1, showing a modification of the invention.
Fig. 4 is a transverse section on line y. y fig. 3.
Referring more particularly to figs. 1. and 2. The handle A is provided with a
sliding or guided spring-catch B which engages with notches or teeth C or their
equivalent cut on the spindle or rod D and holds the handle A in place. The spindle D
is preferably made square and the notches, C, preferably in the form of ratchet teeth,
are cut on one or more of its sides. A number of notches may be provided so that
the handle can be secured in any desired position. The catch B is made of a piece of
sheet metal and is preferably square in shape, having at its centre a hole ɗ, rather
larger than the spindle, through which the said spindle passes.
One edge d of the hole is preferably beveled to correspond with the slope of the
notches C, and the outer edge of the catch, remote from the beveled edge d³, is pro-
vided with a projection d², which passes through the neck of the handle and protrudes
slightly beyond it. The catch is preferably located within a shallow recess in the end
of the handle neck and is held in position by a cover plate E, or its equivalent, the
said plate being secured to the neck by the inturned edges a thereof, or by other
suitable means. A bent spring F, or spring of other suitable form, is placed below
that edge of the catch which is remote from the projection d².
The catch is held in engagement with the notches by means of the spring F but if
the projection d² be pressed inwards from the outside of the handle the catch is moved
clear of the notches and the handle may then be removed. The notches and catch
are so formed that the handle can easily be put on to the spindle in the required
position, but cannot be removed therefrom without pressing the spring and disengaging
the catch.

page_text: Figs. 3 and 4 show another method in which our invention may be applied to
handles, especially to those baving small necks. In this case the projection d' is
shown flush with the outer edge of the neck, and it may be depressed by a penknife
or other suitable instrument, when it is desired to disengage the catch. The catch is
held in position as before by a plate E, or other metallic device but the plate is
placed over it at the end of the handle neck nearest the lock and it is secured to the
said neck by rivets or screws a¹. These rivets may conveniently form guides for the
sliding catch. The spring F is in this instance, a flat spring, bent to the contour of
the interior of the handle. Its outer end passes through a slot f in the neck and
rests (as in figures 1 and 2), against the edge of the catch. The inner end of the
spring is fastened, as at a², to the neck, preferably before the outer part of the handle
is attached thereto.
A knob or handle constructed in accordance with our invention may be placed at
each end of the spindle I), but generally it is sufficient to put it at one end only.
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
1st. The manufacture of door or gate handles or knobs having a ratchet rack or its
equivalent on the spindle and a spring actuated catch in the knob, catching on said
rack, such catch having a projection or its equivalent capable of being pressed back
from the other side of the knob by external pressure and of thus being liberated,
substantially as described.
2nd. The fastening devices for door or gate handles or knobs, substantially as set
forth in figures 1 and 2, and also the modification set forth in Figures 3 and 4.
