PROVISIONAL SPECIFICATION.
Improvements in Fastenings for Door Knobs or Handles.
I, JOHN JAMES BAILEY, of Hazelwood, Woodside Park, Finchley, in the
County of Middlesex, Dental Surgeon, hereby declare the nature of this
invention to be as follows:-
In the Complete Specification filed in pursuance of my application for Letters
Patent No. 7,624 of the year 1894, I describe an invention (hereinafter termed
my prior invention) of improvements in fastenings for door knobs or handles.
My present invention differs therefrom in several particulars.
In order that the nature of my invention may be readily understood I shall
proceed to describe it with reference to a contemplated form of my invention, the
said contemplated form serving as a type or example and being illustrated in the
accompanying sheet of drawings.
In the said drawings

to r of Figure 8.
Figure 13 is an inner face view of a modified form of inner ferrule E.
Referring now to Figure 1. A is the door and B the spindle, the said spindle
being similar to that described in my prior Specification, that is to say square or
nearly so in cross section and threaded at the angles. C is the rose or ornamental
washer usually employed in such cases. E is the inner ferrule shown separately in
Figures 2 and 3. It consists of a cylindrical body e with a flange at its inner
extremity e¹ and is perforated with a central circular orifice e². This orifice has a
female thread to enable it to screw on the spindle B. The external surface of the
body e bears a male thread for the purpose of engagement with the outer ferrule
hereafter to be described. The body e is cut away at the part e to take the web
of a webbed washer. This webbed washer F which is shown separately in Figure 4
is an ordinary flat washer bearing the web f. When the said webbed washer is
passed over the inner ferrule the web lies close upon one of the flat sides of the
spindle and thus prevents the inner ferrule from being screwed or rotated upon the
said spindle. G is the outer ferrule shown in position in Figure 1 and separately
in Figures 5, 6 and 7. It consists of a barrel g₁ having a flange g² projecting
outwardly which flange may conveniently have a milled edge. The inner surface 9
is furnished with a female thread to enable it to screw over the body e of the inner
ferrule. is an inner flange or shoulder the function of which will be hereafter
explained. H is the binding washer shown separately in Figures 8, 9 and 10. It
is perforated as shown, the said perforation being large and circular towards the

page_text: outer face and square and smaller at the inner face where it fits over the spindle B.
The surface has a female thread cut on it for the purpose bereinafter to be
mentioned. D is the door kuob or handle fitted as usual with the square orifice d
and having an annular recess d' into which the outer end of the outer ferrule fits.
The part has a male thread cut upon its extremity as shown in Figures 1
and 12. d is the inner annular extremity of the knob which in position comes
preferably up to the flange g².
The application of my invention is as follows. Having thrust the spindle through
the door and rose as shown in Figure 1 I next screw the inner ferrule E over the
spindle B till it is close to the said rose C and then push the webbed washer F over
the barrel e of the inner ferrule flush against its flange e¹.
I now take the handle or knob D and in its recess d¹ I place the outer end of the
ferrule G. I then drop the binding washer H through the outer ferrule and screw
it over the part d², whose male thread now engages the female thread of the
surface h, until the flange 9' is pressed lightly against the bottom of the recess d³.
This brings the end d³ of the knob D up to the flange g² of the outer ferrule so
that the outer ferrule G is now securely attached to the knob D, whilst being at
the same time free to rotate therein.
I now thrust the knob D over the spindle until the outer ferrule comes in contact
with the inner ferrule when I screw the outer ferrule over the inner ferrule giving
the necessary helical motion when grasping the flange 92 until the two ferrules are
tightly screwed together. The knob D is now firmly and effectively held on the
spindle B in proper position for the operation of the lock.
When it is desired to remove the knob D from the spindle B all that requires to
be done is to unscrew the outer ferrule from the inner ferrule by grasping the
flange g² and moving it in the opposite direction to that in which it was moved when
the parts were placed in position: and when the female thread of the outer
ferrule no longer engages the male thread of the inner ferrule the knob can be
withdrawn by sliding it off the spindle.
In Figure 13 I show an inner face view of a modified form of inner ferrule by
means of which I am able to dispense with the labour of screwing the inner
ferrule over a long length of spindle. This modified form of inner ferrule is
made with a square orifice and a female thread is then cut on the same so as
to give the orifice the form shown in Figure 13. With this form of orifice the
ferrule can be at once slid up over the spindle flush against or close to the rosc C
and then by giving it an angular movement equal to say one eighth of a revolution
its thread engages with the thread of the Spille and longitudinal motion over
the said spindle is no forger posible. It is then bound in position by the webbed

COMPLETE SPECIFICATION.
Improvements in Fastenings for Door Knobs or Handles.
I, JOHN JAMES BAILEY, of Hazelwood, Woodside Park, Finchley, in the
County of Middlesex, Dental Surgeon, 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 :-
In the Complete Sperifertion accompanying my Letters Patent No. 7,021 dated
the 17th day of April 1604, I decibe 27 intention (hereinafter
my

page_text: prior invention) of improvements in fastenings for door knobs or handles. My
present invention differs therefrom in several particulars.
In order that my present invention may be readily understood I shall proceed to
describe it with reference to a contemplated form of my invention, the said
contemplated form serving as a type or example and being illustrated in the sheet
of drawings left with the Provisional Specification.
In the said drawings
Figure 1 is a longitudinal section of the parts in position.
Figure 2 is an inner face view of the inner ferrule E.
Figure 3 is an outer face view of the inner ferrule E.
Figure 4 is a face view of the flat webbed washer F.
Figure 5 is an inner face view of the outer ferrule G.
Figure 6 is an outer face view of the outer ferrule G.
Figure 7 is a side elevation of the outer ferrule G.
Figure 8 is an inner face view of the binding washer H.
Figure 9 is an outer face view of the same, and
Figure 10 is a section of the same on the line
Figure 11 is an inner face view of the knob D.
Figure 12 is a longitudinal section of the knob D.
- of Figure 8.
Figure 13 is an inner face view of a modified form of inner ferrule E.
Referring now to Figure 1 A is the door and B the spindle, the said spindle
being similar to that described in my prior Specification, that is to say square
or nearly so in cross section and threaded at the angles. C is the rose or
ornamental washer usually employed in such cases. E is the inner ferrule shown
separately in Figures 2 and 3. It consists of a cylindrical body e with a flange at
its inner extremity e¹ and is perforated with a central circular orifice e². This
orifice has a female thread to enable it to screw on the spindle B. The external
surface of the body e bears a male thread for the purpose of engagement with
the outer ferrule hereafter to be described. The body e is cut away at the
part to take the web of a webbed washer. This webbed washer F which is
shown separately in Figure 4 is an ordinary flat washer bearing the web f.
When the said webbed washer is pa-sed over the inner ferrule the web lies
close upon one of the flat sides of the spindle and thus prevents the inner
ferrule from being screwed or rotated upon the said spindle. G is the outer
ferrule shown in position in Figure 1 and separately in Figures 5, 6 and 7. It
consists of a barrel g' having a flange g² projecting outwardly which flange may
conveniently have a milled edge. The inner surface 93 is furnished with a female
thread to enable it to screw over the body e of the inner ferrule. is an inner
flange or shoulder the function of which will be hereafter explained. H is the
binding washer shown separately in Figures 8, 9 and 10. It is perforated as shown,
the said perforation being large and circular towards the outer face and square and
smaller at the inner face where it fits over the spindle B. The surface has a
female thread cut on it for the purpose hereinafter to be mentioned. D is the door
knob or handle fitted as usual with the square orifice d and having an annular
recess into which the outer end of the outer ferrule fits. The part d' has a
male thread cut upon its extremity as shown in Figures 1 and 12. d³ is the inner
annular extremity of the knob which in position comes preferably up to the
flange g².
The application of my invention is as follows. Having thrust the spindle
through the door and rose as shown in Figure 1 I next screw the inner ferrule E
over the spindle B till it is close to the said rose C and then push the webbed
washer F over the barrel e of the inner ferrule flush against its flange e¹.
I now take the handle or knob D and in its recess d I place the outer end of the
ferrule G. I then drop the binding washer H through the outer ferrule and screw
it over the part d', whose male thread now engages the female thread of the
surface, until the flange 9 is pressed lightly against the bottom of the recess d¹.
This brings the end of the knob D up to the flange g of the outer ferrule so

page_text: that the outer ferrule G is now securely attached to the knob D, whilst being at
the same time free to rotate therein.
I now thrust the knob D over the spindle until the outer ferrule comes in contact
with the inner ferrule giving the necessary helical motion when grasping the
flange g until the two ferrules are tightly screwed together. The knob D is now
firmly and effectively held on the spindle B in proper position for the operation
of the lock.
When it is desired to remove the knob D from the spindle B all that requires
to be done is to unscrew the outer ferrule from the inner ferrule by grasping the
flange and and moving it in the opposite direction to that in which it was moved
when the parts where placed in position: and when the female thread of the outer
ferrule no longer engages the male thread of the inner ferrule the knob can be
withdrawn by sliding it off the spindle.
In Figure 13 I show an inner face view of a modified form of inner ferrule by
means of which I am able to dispense with the labour of screwing the inner ferrule
over a long length of spindle. This modified form of inner ferrule is made with a
square orifice and a female thread is then cut on the same so as to give the orifice
the form shown in Figure 13. With this form of orifice the ferrule can be at once
slid up over the spindle flush against or close to the rose C and then by giving
it an angular movement equal to say one eighth of a revolution its thread engages
with the thread of the spindle and longitudinal motion over the said spindle is no
longer possible. It is then bound in position by the webbed washer.
I desire it to be understood that I do not limit myself to the precise construction
and arrangement of parts herein set forth as, the principles of construction being
understood, considerable modification of form and arrangement can be made without
departing from the spirit of my invention.
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 1
claim is
1. In a fastening for door knobs or handles, what I have termed an inner ferrule
that is to say a ferrule consisting of a cylindrical body perforated with a central
circular threaded orifice, its external surface bearing a male thread and cut away,
substantially as and for the purposes set forth.
2. In a fastening for door knob or handles the modified form of immer ferrule
which differs from that defined in the preceding claim in that it neatral cities
and tiredeti, suunfantially as and for the purpose, set forth.
3. The combination of an inner ferrule and r webbed washer substantially ru
and for the purpose set forth.
4. The coalination of an inner ferrule a webbed her and an inter ferrule
substantially s et forth.
6. The arrangement and combination of parts substantially as set forth with
reference to Figure 1.
6. The specific form of inner ferrule shown in Figures 2 and 3.
7. The specific form of inner ferrule shown in Figure 13.
