page_text: LETTERS PATENT to William Meakin, of Number 3; Great Woodstock
Street, in the Parish of Marylebone, London, Engineer, for the In-
vention of "CERTAIN IMPROVEMENTS IN THE CONSTRUCTION OF ADJUSTABLE
Lock SpryDLES AND THE FITTINGS THERETO
"
Sealed the 11th June 1869, and dated the 14th December 1868.
PROVISIONAL SPECIFICATION left by the said William Meakin at
the Office of the Commissioners of Patents, with his Petition, on the
14th December 1868.
I, WILLIAM MEAKIN, of Number 3, Great Woodstock Street, in the
Parish of Marylebone, London, Engineer, do hereby declare the nature
of the said Invention for "CERTAIN IMPROVEMENTS IN THE CONSTRUCTION OF
ADJUSTABLE LOCK SPINDLES AND THE FITTINGS THERETO," to be as follows:-
In this arrangement one handle or knob of china, metal, or other
material is firmly secured to one end of a square spindle in any customary
manner with the ordinary attachment revolving in a "rose" plate firmly
secured to the door. The other handle or knob has (if of china or such
like material) a metal bush or ferrule affixed to it, in the centre of which
is a hole accurately tapped to suit a screw thread cut on the angles of
the spindle; this metal bush or ferrule has a projecting collar forming a
circular recess to receive a disc of brass, iron, or other material. A squaro

page_text: aperture is formed in the centre of the said disc, through which the
square spindle passes allowing of longitudinal motion only, and the disc
is pierced transversely with four or more holes tapped to receive a set
screw or pin, as hereafter explained. The disc also has a circular pro-

collar of the ferrule of the knob or handle before mentioned (which is
provided with holes corresponding to those in the disc) revolves in a
bearing or rose plate secured to the door, which carries a loose "rose
of china or other material, having a corresponding screw thread, by
means of a screwed projecting rim; an opening is provided in this rim
by which the set screw or pin can be passed through the collar of
the ferrule of the knob or handle and be screwed into the tapped hole of
the disc; the head of the set screw or pin when "home

The method of adjustment. obtained by this Invention is as follows:
The two bearing or rose plates being scoured in position on the door, the
spindle with one knob or handle fixed thereon, is passed through them
and through the "follower" of the lock, the disc is passed on to the
projecting portion of the spindle, and the other knob is then screwed
on to the spindle until a good working fit is obtained. The set screw or
pin is then passed through the aperture formed in the rim of the bearing
or rose plate, through the nearest corresponding hole in the collar on the
ferrule of the knob or handle into one of the tapped holes provided in
the disc, and then firmly screwed up so as to "jam" against one of the
square faces of the spindle. The whole arrangement is thus rendered
free from any shake or chatter and perfectly firm, and when the "rose"
is screwed on to the rim of the bearing or rose plate no screws are
visible.
One important advantage gained by this Invention is that any ordinary
carpenter can readily understand the method of fixing and adjusting this
lock furniture, no special tool being required to cut away any portion of
the door, and the only fixing requisite is the screws to secure the bearing
or rose plates to the door.
I do not confine myself to the precise details herein referred to, as
both the materials to be employed and any slight deviation in the forms
described may be varied to suit special circumstances.

filed by the said William Meakin in the Great Seal Patent Office
on the 14th June 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
MEAKIN, of Number 3, Great Woodstock Street, in the Parish of Mary-
lebone, London, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of December, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Meakin, Her special licence that
I, the said William Meakin, my executors, administrators, and assigns,
or such others as I, the said William Meakin, my executors, admi-
nistrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "CERTAIN IMPROVE-
MENTS IN THE CONSTRUCTION OF ADJUSTABLE LOCK SPINDLES AND THE FITTINGS
THERETO," upon the condition (amongst others) that I, the said William
Meakin, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same .to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that' I, the said William Meakin, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to he particularly described and ascertained in and by the
following statement and accompanying Drawing
-
In this arrangement one handle or knob of china or other material is
firmly secured to one end of a square spindle in any customary manner
with the ordinary attachment, revolving in a rose plate firmly secured
to the door. The other handle or knob has (if of china or such like
material) a metal bush or ferrule affixed to it, in the centre of which is
a hole accurately tapped to suit a screw thread cut on the angles of the
spindle; this metal bush or ferrule has a projecting collar forming a

page_text: circular recess to receive a disc of brass, iron, or other material. A
square aperture is formed in the centre of this said disc, through which
the square spindle passes allowing of longitudinal motion only, and this
disc is pierced transversely with one or more holes tapped to receive a
set screw or pin, as hereafter explained. The collar of the ferrule of the
knob or handle mentioned (which is provided with holes corresponding
to those in the disc) revolves in a bearing or "rose plate" secured to the
door which carries a loose "rose" of china or other material having
a corresponding thread; by means of the screwed projecting rim an
opening is provided in this rim by which the set screw or pin can be
passed through the collar of the ferrule of the knob or handle, and he
screwed into the tapped hole of the disc, the head of the set screw or
pin when "home" lying in the thickness of the collar and serving to
connect it firmly to the disc.
-
The method of adjustment obtained by this Invention is as follows:-
The two bearings or "rose plates" being secured in position on the door
the spindle with one knob or handle fixed thereon is passed through
them and through the "follower" of the lock, the disc is passed on to
the projecting portion of the spindle, and the other knob is then screwed
on to the spindle until a good working fit is obtained. The set screw or
pin is then passed through the aperture formed in the rim of the bearing
or rose plate through the nearest corresponding hole in the collar on the
ferrule of the knob or handle into one of the tapped holes provided in
the disc, and then firmly screwed up so as to "jam" against one of the
square faces of the spindle. The whole arrangement is thus rendered
free from any shake or chatter and perfectly firm, and when the "rose'
is screwed on to the rim of the bearing or "rose plate" no screws are
visible.
"
One important advantage gained by this Invention is that any ordinary
carpenter can readily understand the method of fixing and adjusting this
lock furniture, no special tool being required to cut away any portion of
the door, and the only fixing requisite is the screws to secure the "rose"
or bearing plate to the door.
Fig. 1 is a side view, partly in section, shewing the details of my 3
method of fitting lock spindles in position, in which A is the knob or
handle, shown as secured to one end of the spindle B and revolving in

page_text: the "rose plate" C, which carries the "rosc" D by means of the pro-.
jecting rim having a thread formed upon it; E is the knob or handle
having a metal bush or ferrule F to receive the screwed portion of the
spindle B. This metal bush or ferrule has a projecting collar forming a
circular recess to receive the disc G, which has a square hole in the
centre through which the spindle B passes. In the disc G one or more
tapped holes are provided to receive the set screw H.
Fig. 2 is a front view of the "rose plate," having a portion of its
projecting screwed rim cut away to allow of access to the set screw H
while fixing the spindle B.
Fig. 3 is an end view of the knob or handle E, shewing the set
screw H, connecting the collar of the ferrule F of the knob E to the
disc G, and firmly securing the spindle B.
Fig. 4 is a side elevation of the knob or handle E and the ferrule F,
in the collar of which suitable holes are formed to receive the set
screw H.
Having thus described the nature of my said Invention I wish it to be
understood that I do not confine myself to the precise arrangements
herein referred to, as both the materials to be employed, and the exact
details of the parts described may be varied, the number of holes for
adjustment may be increased or diminished, and both the knobs or
handles may be fitted with the same or similar disposition of parts to
obtain increased length of adjustment; but what I claim is, the general
arrangement, substantially as herein described and shewn in the accom-
panying Drawing.
In witness whereof, I, the said William Meakin, have hereunto set
my hand and seal, this Twelfth day of June, in the year of our
Lord One thousand eight hundred and sixty-nine.
