page_text: LETTERS PATENT to Thomas Nott, of Southampton Buildings, Holborn, for the
Invention of "IMPROVEMENTS IN FIXING HANDLES AND KNOBS TO LOCK
SPINDLES AND IN THE APPLIANCES THEREFOR, SUCH IMPROVEMENTS BEING ALSO
PARTLY APPLICABLE TO OTHER PURPOSES."
Sealed the 23rd March 1877, and dated the 17th January 1877.
PROVISIONAL SPECIFICATION left by the said Thomas Nott at the Office of
the Commissioners of Patents on the 17th January 1877.
THOMAS NOTT, of Southampton Buildings, Holborn. "IMPROVEMENTS IN FIXING
HANDLES AND KNOBS TO LOCK SPINDLES AND IN THE APPLIANCES THEREFOR, SUCH
IMPROVEMENTS BEING ALSO PARTLY APPLICABLE TO OTHER PURPOSES."
This Invention consists in an improved means of and appliances for securing
handles, knobs, and other similar articles upon lock and other spindles and shafts,
whereby such handles, knobs, or other articles are 'far more securely and expe-
ditiously fixed thereon than heretofore.
In applying my Invention to fixing handles and knobs upon lock spindles I
proceed as follows:-I either drill or cut a suitable orifice in the wood or other
material intended to form the knob or handle of the lock; I then take one of my
improved spindles, which are fully described and illustrated in the Specification of
my Patent, No. 3265, of 1873, and after jagging or cutting the solid end of such
spindle I place the same in the bolt of a press, and force down such solid jagged end
to any convenient depth into the orifice provided for its reception. I then enclose
the spindle when so fixed with a suitable metal collar, preferably of a wedge-like
shape, which I will hereafter call a ferrule wedge, and by means of a press or in
any other convenient manner I drive such collar or wedge into the substance of
the knob or handle, and thereby the spindle becomes so firmly wedged therein as
to preclude all possibility of its either getting loose or coming off.
A further improvement in reference to the application of my Invention to the
fixing of door handles consists in making the rose with two or more pins or prods
fixed to or formed on the under side thereof, which pins or prods take into the
substance of the door and so securely attach the rose thereto; or instead of such

page_text: pins or prods I sometimes prefer to use a metal collar, which I either affix to or
form on such rose, as may be most convenient, such metal collar being made slightly
taper both in form and thickness at its outer projecting end so as to permit of its
being forced into and becoming firmly wedged in the substance of the door, thus
preventing all possibility of the spindle in its action chafing against and thereby
gradually wearing away the substance of the door immediately around it, as now
often occurs. By this means I also entirely overcome the great disadvantage of
the present method of fixing door handles which now frequently become displaced,
loose, and comparatively useless, owing to the screws or pins by which the rose is
attached to the door becoming loose and falling out.
My Invention may also be applied with great advantage to the fixing of drawer
knobs and handles. In doing this I entirely dispense with any other spindle or
shank than that formed upon the knob or handle itself, which spindle or shank I
form hollow to a suitable depth and with (a suitable internal female thread formed
thereon, if desired, and I split the same in a similar manner as is described in the
Specification of my Patent herein-before referred to. Having dipped such shank
or spindle into the glue in the ordinary way I then place it in the hole formed in
the drawer for its reception, and either insert or force in a suitable screw or wedge,
thus wedging out the hollow end of the spindle or shank against the substance of
the drawer and so firmly securing it thereto.
My Invention may also be applied to the fixing of driving wheels, discs, drums,
and other similar mechanism upon shafting and for other similar purposes.
I wish it to be understood that I do not confine myself to any particular form of
spindle, as the same may be varied as circumstances may require.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Thomas Nott in the Great Seal Patent Office on the 7th July 1877.
THOMAS NOTT, of Southampton Buildings, Holborn. "IMPROVEMENTS IN FIXING
HANDLES AND KNOBS TO LOCK SPINDLES AND IN THE APPLIANCES THEREFOR, SUCH
IMPROVEMENTS BEING ALSO PARTLY APPLICABLE TO OTHER PURPOSES."
This Invention consists in an improved means of and appliances for securing
handles, knobs, and other similar articles upon lock and other spindles and shafts,
whereby such handles, knobs, or other articles are far more securely and expe-
ditiously fixed thereon than heretofore.
And in order that my said Invention may be better understood and readily
carried into effect, I will now, with the aid of the accompanying Drawings, proceed
to more particularly describe and ascertain the nature of the same, that is to say:-
In applying my Invention to fixing handles and knobs upon lock spindles I
proceed as follows:-I either drill or cut a suitably sized orifice, either square,
circular, or of any other convenient form, in the wood or other material intended to
form the knob or handle of the lock. This orifice is indicated at a¹, Figure 2, of
the accompanying Drawings. I then take one of my improved patent lock spindles
which are fully described and illustrated in the Specification of my Patent,
No. 3265, of 1873, and after jagging or cutting the solid end of such spindle, as
shewn at a, Figure 1, of the accompanying Drawings, which is a view of one of my
improved patent spindles, so jagged at its solid end as aforesaid I place the same
in the bolt of a press and force down such solid jagged end to any convenient depth
into the orifice so provided for its reception, as shewn at Figure 7, such serrations
serving to contribute to firmly secure the same in the knob. I then enclose the
spindle when so fixed in the knob with a suitable metal collar, which I prefer to
make of a wedge-like shape and which I will hereafter call a ferrule wedge. Such
metal collar I by means of a press or in any other convenient manner drive into the
substance of the knob or handle, as shewn at b, Figure 2, of the accompanying

page_text: Drawings, which is a sectional view of a door knob with one of such metal collars
inserted therein, and thereby the spindle becomes so firmly wedged therein as to
preclude all possibility of its either getting loose or coming off.
Another feature of my improvements in reference to the application of my
Invention to the fixing of door handles consists in providing the rose on its under
side with three or more pins or prods of a taper shape, and either affixed thereto in
any convenient manner or formed thereon, as shewn at c, Figure 3, of the accom-
panying Drawings, which shews a side elevation of a rose so furnished with taper
pins or prods, and which taper pins or prods take into the substance of the door
itself and so securely attach the rose thereto. This method of affixing the rose to
the door is more especially adapted for economical purposes, such as fitting my
improved lock furniture to the doors of cottages, warehouses, and in other similar
situations where strength and utility are more especially requisite; or instead of
such pins or prods I sometimes prefer to use a metal collar. and socket which I
either affix to or form on such rose as may be most convenient, the socket of which
metal collar is inade slightly taper both in form and thickness at its outer projecting
end, as shewn at d, Figure 4, which shows a side elevation of a rose fitted with
one of such taper metal collars so as to permit of its being forced into and becoming
firmly wedged in the substance of the door, thus preventing all possibility of the
spindle in its action chafing against and thereby gradually wearing away the
substance of the door immediately around it, as now often occurs. The rim or
flange forming the collar may be of any convenient width, and such collar and
socket is equally adapted for application to roses either of china, glass, wood, or
other material, and may be either countersunk therein or be laid over the top of
the inner recess of the rose in the form of a thin metal plate. By this means I also
entirely overcome the great disadvantage of the present method of fixing door
handles which now frequently become displaced, loose, and comparatively useless,
owing to the screws or pins by which the rose is attached to the door becoming
loose and falling out.
My Invention may also be applied with great advantage to the fixing of drawer
knobs and handles. In doing this I entirely dispense with any other spindle or
shank than the nozzle formed upon the knob or handle itself, which nozzle I form
hollow to a suitable depth and if desired with a suitable internal female thread
formed thereon, and I split the same in a similar manner as is described in the
Specification of my Patent, No. 3265, of 1873, herein-before referred to; Figure 5
shews a sectional view of a drawer knob constructed on this principle. Having
dipped such nozzle into the glue in the ordinary way I then place it in the hole
formed in the drawer for its reception, and either insert or force in a suitable screw
or wedge, shewn at Figure 6, thus wedging out the hollow end of the nozzle or
shank against the substance of the drawer and so firmly securing it thereto.
My Invention may also be applied to the fixing of driving wheels, discs, drums,
and other similar mechanism upon shafting and for other similar purposes.
I wish it to be understood that I do not confine myself to any particular form
of spindle, as the same may be varied as circumstances may require.
Having now particularly described and ascertained the nature of my said
Invention and the manner of carrying the same into effect, I would have it under-
stood that what I claim and desire to secure by the herein-before in part recited
Letters Patent is,-
1. The serrating the solid end of my improved patent lock spindle, substantially
in the manner and for the purposes herein-before described and illustrated.
2. The use and application of a taper metal collar or ferrule wedge, for the purpose
and in the manner herein-before described and illustrated.
3. The affixing to or forming on the under side of the rose a suitable number of
taper pins or prods, substantially in the manner and for the purpose herein-before
described and illustrated.
4. The use and application of a metal collar and socket, in the manner and for
the purposes herein-before described and illustrated.

page_text: 5. The use, either separately or in any suitable combination thereof, of the
various improvements herein-before described and illustrated for the purposes
herein-before referred to.
In witness whereof, I, the said Thomas Nott, have hereunto set my hand
and seal, this Sixth day of July, in the year of our Lord One thousand
eight hundred and seventy-seven.
THOMAS NOTT. (L.S.)
