Improved Means of Attaching Knobs to Spindles.
JOHN EDWIN BROWNE Agent 57, Holborn Viaduct London E:C. do hereby
declare the nature of this invention to be as follows:-
Primarily a means of attatching a knob on a spindle. I employ for this purpose
an ordinary square spindle threaded on the edges. I fix in it a fly-nut or rose
which is screwed to run on the spindle in the same way as it has been done before.
I however on the face of the said fly nut or rose make bayonet slots or groves: on
the neck of the knob I put studs or catches with heads on same, which heads are
The nut has a
passed through the large parts of the bayonet slots or groves.
square hole to fit the spindle. To fix the same the fly nut is first screwed up to the
door or lock, the knob is then pushed on the spindle until the studs or catches pass
through the large parts of bayonet slots or groves that are in the fly nut or rose.
The fly nut or rose is then turned so as to bring the shanks of the studs or catches
in the small parts of the slots or groves which securely fixes the knob on the
spindle.
I can if thought necessary so as to prevent by any possible jarring or shaking of
the door the fly nut or rose from travelling back on the spindle, fit a spring or
catch in the fly nut or rose, allowing the fly nut or rose to move in the direction to
fix, but not in the opposite direction so as to pull off again; or, I could put a
screw, wedge or key into the fly nut or rose to come between the heads of the studs
or catches and the large parts of the bayonet slots or catches, which would prevent
when once fixed the fly nut or rose from turning back on the spindle.
Dated this 20th day of December 1892.
COMPLETE SPECIFICATION.
Improved Means of Attaching Knobs to Spindles.
JOHN EDWIN BROWNE 57, Holborn Viaduct London E.C. Agent 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:—
This invention relates to means of attaching or securing knobs to spindles.
In order that this invention may be understood I hereby annex a sheet of
drawing illustrating the same.
Fig. 1. represents the knob marked A with clamps attached marked C.
Fig. 2. D is a fly nut or rose with slots.
Fig. 3. represents knob & rose attached to screwed spindle.
In carrying this invention into practice I imploy the ordinary square spindle H
with screwed threaded edges, and apply the fly rose D which is screwed to fit the
same spindle. In fixing same I first screw rose D on to spindle, I then slip knob
which has a square hole on to square spindle-bringing the heads of clamps
opposite to the large parts of slot F to rose D.
The knob is then pressed tight against the rose-which rose is turned so that the
heads of clamp come into small parts of slot F which prevents the knob from being
drawen off.

page_text: Having now described the nature of my invention and in what manner the same
has to be performed-I declare what I clame is
An improved method of attaching knobs, to spindles—by means of a fly rose with
slots therein corresponding with the clamps on the knob which secures knob with
square hole on said square screwed spindle.
