Improvements in and relating to Attaching Door Knobs or Handles
to Spindles.
1, WILLIAM BROCKLEBANK of 46 Johnson Street, Cheetham, Manchester, Gentleman
do hereby declare the nature of this invention to be as follows:
My improvements relate to improved means of attaching door knobs and handles to
their spindles; and for this purpose I form the spindle preferably of square section
at that end receiving the knob; and in the spindle I form a suitable inclined
longitudinal recess at one or both ends; the deepest part of the recess being at the
end of the spindle. At the shallowest end of the recess, I attach a steel spring,
formed at its opposite or outer end with one or more projections or heads of such a
height, that when the outer end of the spring is depressed to the bottom of the recess
in the spindle, the head or heads do not project above it; but will allow a knob. or
handle to be passed on to the spindle. The end of the hole in the knob or handle
nearest the door, is formed of the same shape as and to fit the spindle to a suitable
depth; and is then recessed-in such a manner-that when the knob or handle has
been passed on to the spindle up to the door, the head of the spring being no longer
held down by that part of the hole in the knob which fits the spindle, springs up into
the recess formed in the knob, and by this means is effectually held on or attached to
the spindle.
In some cases I form the spring with several projections or heads, one in advance
of the other, so that the same spindle and knob or knobs may suit varying thicknesses
of doors.
For removing the knobs or handles from their spindles, I form a hole in the knob
opposite to and down to the head on the spring, so as to admit any suitable article to
press the projection on the spring down into the recess in the spindle, and allow the
knob or handle to be withdrawn therefrom.

Improvements in and relating to Attaching Door Knobs or Handles
to Spindles.
I, WILLIAM BROCKLEBANK of 46 Johnson Street, Cheetham, Manchester, Gentleman,
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 improvements relate to improved means of attaching door knobs and handles to
their spindles; and for this purpose I form the spindle preferably of square section at
that end receiving the knob; and in the spindle I form a suitable inclined longitudinal
recess at one or both ends; the deepest part of the recess being at the end of the
spindle. At the shallowest end of the recess, I attach a steel spring, formed at its
opposite or outer end with one or more projections or heads of such a height, that
when the outer end of the spring is depressed to the bottom of the recess in the
spindle, the head or heads do not project above it; but will allow a knob or handle to
be passed on to the spindle. The end of the hole in the knob or handle nearest the
door, is formed of the same shape as and to fit the spindle to a suitable depth; and is
then recessed-in such a manner-that when the knob or handle has been passed on

page_text: to the spindle up to the door, the head of the spring being no longer held down by
that part of the hole in the knob which fits the spindle, springs up into the recess
formed in the knob, and by this means is effectually held on or attached to the
spindle.
In some cases I form the spring with several projections or heads one in advance of
the other, so that the same spindle and knob or knobs may suit varying thicknesses of
doors.
For removing the knobs or handles from their spindles, I form a hole in the knob
opposite to and down to the head on the spring, so as to admit any suitable article to
press the projection on the spring down into the recess in the spindle, and allow the
knob or handle to be withdrawn therefrom.
And in order that my invention may be fully understood, and readily carried out,
and into effect; I will proceed to describe the accompanying sheet of drawings;
reference being had to the letters and figures marked thereon.
Figure 1, is a side sectional elevation of my improved spindle and knob.
Figure 2 is a plan of the spindle with the knob or handle in section.
Figure 3 is an end transverse section through the line X. Y in Fig. 1.
Figure 4 is a side sectional elevation of my improved spindle and handle, as
arranged for cupboard doors, drawers, &c.
Similar letters of reference denote corresponding parts throughout the several
views.
In these views, A is the knob or handle.
B is the spindle, formed preferably of square section, and having an inclined
longitudinal recess C at both ends of the spindle-as shewn at Fig. 1; and at one
end as shewn at Fig. 4.
E is the catch spring-fastened to the spindle by one or more rivets or screws-and
formed with the head H, of such a thickness, that when it is depressed down into the
groove C, it will allow the knob A to be passed on to the spindle B.
The hole in the knob A is fitted with a metal or other suitable liner or bush F, of
the same shape as, and to fit the spindle B.
The upper part of liner E, has formed in it a number of slots L. L-one in advance
of the other, and into one of which the head H of spring catch E engages itself,
when the knob A is passed onto the spindle B, up to the door. The spring catch E. H
then assumes its normal straight position as shewn in the drawings.
For removing the knob A from the spindle B, I have a hole D in the knob A, to
admit of the spring catch E. H being pressed down into the recess C-by any
suitable article until the head H is level with the spindle, so that the knob can be
withdrawn from it.
I usually form a slit P in the head H, so that the article pressing down the
spring E. H may continue to press it down into the recess C until the head H has
passed it.
In Figure 4-M is the cupboard door or drawer; and the spindle B is fitted at one
end with the catch K, turning into the slot shown in L.
The liner F is fastened to knob A by a collar and screws, in the usual manner.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. Spindles for door knobs or handles formed with a groove C, at one or both ends;
and fitted with a spring catch E H, in combination with a rack or slots L. L in the
liners F of door handles A. A; as described and illustrated in Figures 1-2-3
and 4 of the accompanying drawings.
2. Door handles fitted with a liner F, having formed in it a rack or slots L. L; in
combination with the recessed spindle B, and spring catch E. H; substantially as
described and illustrated in Figures 1-2-3 and 4 of the drawings annexed, or any
mere modification thereof.
3. In spindles for door handles, the use of the spring catch E, H, constructed with

page_text: the head H, in combination with the recess or groove C formed in the spindle B, at
one or both ends; substantially as described in the Figures 1-2-3 and 4 of the
drawings hereunto annexed, or any mere modification thereof.
4. In door handles, the use of the liner F, formed with a rack or slots L, L; in
combination with the spring catch E H, and recessed spindle B; substantially as
described and illustrated in Figures 1 to 4 herewith, or any mere modification
thereof.
5. The use of the pusher hole D in handles A. A, in combination with the handle A
and spindle B; substantially as described and illustrated in the drawings hereunto
annexed.
