Improvements in Means for Attaching Door Knobs or Handles to
their Spindles.
We, GEORGE SKINNER, of 138 Clarence Street, Bolton, in the County of
Lancaster, Draughtsman, and JOHN HILL, of 73 Church Street, Bolton aforesaid,
Foreman Fitter, do hereby declare the nature of this invention to be as follows:-
Our invention relates to improvements in means for attaching door knobs or
handles to their spindles, and the chief object of our improvements is to fix the
knobs or handles firmly and securely in position without the use of any screws or
nails and at the same time to enable them to be quickly and readily removed or
adjusted on their spindles when required.
In carrying our invention into effect we prefer to cast the spindle into or other-
wise rigidly connect it to one knob or handle. In two opposite sides or in three
sides of the spindle we cut at any suitable distance apart any convenient number of
grooves, and after the spindle with one knob or handle secured thereto, as above
mentioned, has been passed through the hole in the door and lock or latch, we pass
the usual rose over the end of the spindle and then slip a washer in which is cut an
open slot into one of the sets of grooves cut in the spindle; this washer should abut
against the boss of the rose but, should there be any space left, a filling up washer
can be placed between the slotted washer and the boss of the rose; we then attach
the second knob or handle to the boss of the rose preferably by means of a spring
coupling, the end of the square spindle entering a square hole formed to receive it
in the knob or handle.
Any suitable form of spring coupling to connect the knob or handle to the boss
of the rose may be employed; but we prefer to use a coupling which will enable
the knob or handle to be turned while the rose remains stationary.
A convenient
form of coupling consists of a spring fitted in a groove inside the knob or handle
and engaging a groove on the boss of the rose.
In cases where screws are not considered objectionable we might couple the knob
or handle to the rose by a screw or screws the points of which enter the groove in
the boss of the rose.
Instead of the slotted washer and grooved spindle a cotter pin might be passed
through a hole or slot in the spindle so as to act as a key, and a filling up washer
or piece would be employed if required.
The rose may be held stationary in any convenient manner as for example by
fitting a squared boss thereon into a square recess in the door.
Again instead of forming the groove for the spring or other coupling in the boss
5 of the rose we might form it in the slotted washer or in a filling up washer; and
instead of attaching one knob or handle rigidly both might be connected to the
spindle by spring or other couplings as described.

Improvements in Means for Attaching Door Knobs or Handles to
their Spindles.
We, GEORGE SKINNER, of 138. Clarence Street, Bolton, in the County of
Lancaster, Draughtsman, and JOHN HILL, of 73 Church Street, Bolton aforesaid,
Foreman Fitter, 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 :-
Our invention relates to improvements in means for attaching door knobs or
handles to their spindles, and the chief object of our improvements is to fix the
knobs or handles firmly and securely in position without the use of any screws or
nails and at the same time to enable them to be quickly and readily removed or
adjusted on their spindles when required.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Figs. 1, 2, 3 and 4 are sectional views of door knobs connected to their spindles
according to our improvements the locks being omitted.
Fig. 5 is a view of a slotted washer and
Fig. 6 is a view of the spring used in the knob.
Referring first to Fig. 1, a designates one knob or handle in which the spindle b
is cast or otherwise rigidly connected thereto. The spindle is passed through
the rose c and through the door d and through the rose e on the other side
of the door the roses c and e are secured to the door by screws f in the usual way.
On the end of the spindle is a washer g and a lock nut, the washer g being used
to fill up the space or recess in the second knob or handle a¹; this knob a' we attach
to the boss of the rose e by means of a spring coupling the end of the square
spindle enters the square hole formed to receive it in the knob or handle a!.
Any suitable form of spring coupling to connect the knob or handle a¹ to the
boss of the rose e may be employed; but we prefer to use a coupling which will
enable the knob or handle to be turned while the rose remains stationary and fixed
in position as shown.
A convenient form of coupling consists of a spring i (see Fig. 6) fitted in a
groove inside the knob or handle a' and engaging a groove on the boss of the
rose e.
In Fig. 2 a loose square spindle is employed the ends of which enter the square
recesses in two loose knobs a¹ which are connected to the roses e by the spring
couplings g as in Fig. 1.
In Fig. 3 the grooved boss of the rose e acts as a nut screwed upon the spindle b,
a locknut being also employed as in Fig. 1 this arrangement being particularly
applicable for what are known as rim locks.
Fig. 4 shows another arrangement which is intended for a mortice lock as are the
arrangements illustrated by Figs. 1 and 2 and in this case the spindle ò is grooved
to receive the slotted washer k (see Fig. 5) which acts as a key to secure the spindle
instead of the lock nut / shown in Figs. I and 3.
A filling up washer might be employed placed between the slotted washer k and
the boss of the rose.
In cases where screws are not considered objectionable we might couple the knob
or handle to the rose by a screw or screws the points of which enter the groove in
the boss of the rose.
b
Instead of the slotted washer and grooved spindle 6 a cotter pin might be
passed through a hole or slot in the spindle 6 so as to act as a key, and a filling up
washer or piece would be employed if required,

page_text: The rose may be held stationary in any convenient manner as for example by
fitting a squared boss thereon into a square recess in the door.
Again instead of forming the groove for the spring or other coupling in the boss
of the rose we might form it in the slotted washer or in a filling up washer; and
instead of attaching one knob or handle rigidly as shown in Fig. 1 both might be
connected to the spindle by spring or other couplings as described.
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 use and application of a spring coupling for the purpose of attaching a
door knob or handle to the spindle which actuates its lock or latch substantially as
and for the purposes herein set forth.
2. The several arrangements embodying our improvements substantially as
described and as illustrated by the drawings annexed.
Dated this 4th day of October 1892.
