Year: 1857

page_text: LETTERS PATENT to Charles William Ramié, of Camberwell, in the
County of Surrey, for the Invention of "IMPROVEMENTS IN THE MODE' OF
ATTACHING KNOBS TO SPINDLES."
Sealed the 6th November 1857, and dated the 7th May 1857.
PROVISIONAL SPECIFICATION left by the said Charles William Ramié
at the Office of the Commissioners of Patents, with his Petition, on the
7th May 1857.
I, CHARLES WILLIAM RAMIE, of Camberwell, in the County of Surrey, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
MODE OF ATTACHING KNOBS TO SPINDLES," to be as follows:-.
For the purposes of this Invention I make use of a square' or other angular
spindle, on the angles of which a screw is cut in the manner previously known
and practised: At the inner end of the knob is attached a nut, which is
free to revolve about its axis, and tapped to fit upon the screwed angles of
the spindle. To this nut is attached a washer or escutcheon plate, whereby
the nut may be caused to revolve, and the knob consequently drawn forward

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles William Ramié in the Great Seal Patent Office on
the 7th November 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
WILLIAM RAMIE, of Camberwell, in the County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of May, in the year of our Lord One
thousand eight hundred and fifty-seven, in the twentieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Charles William Ramié, Her special licence that I, the said Charles William
Ramié, my executors, administrators, and assigns, or such others as I, the
said Charles William Ramié, my executors, administrators, 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 "IMPROVE-
MENTS IN THE MODE OF ATTACHING KNOBS TO SPINDLES," upon the condition
(amongst others) that I, the said Charles William Ramié, 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 Charles William Ramié, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
For the purposes of this Invention I make use of a square or other angular
spindle, on the angles of which a screw is cut in the manner previously known
and practised. At the inner end of the knob is attached a nut, which is
free to revolve about its axis, and tapped to fit upon the screwed angles of
the spindle. To this nut is attached a washer or escutcheon plate, whereby

page_text: the nut may be caused to revolve, and the knob consequently drawn forward
upon the angular spindle, the end of which fitting into a corresponding hole
in the knob prevents the latter from revolving thereon.
The manner in which my said Invention may be carried into effect will
be readily understood by reference to the accompanying Drawing, where
Fig. 1 represents the spindle of an ordinary door lock, one knob of which is
attached thereto according to my Invention, and is consequently capable of
being adjusted thereon to suit different thicknesses of doors. The other knob
not being required to be adjustable may be fixed upon the spindle in any
convenient manner.
The spindle a, the cross section of which it is preferred to make square,
has cut upon its angles the screw thread b, upon which is fitted the nut c,
capable of being revolved thereon by means of the washer d, and connected
with the knob e by means of the metallic bush f, fixed in the knob, and
having its inner end formed so as to embrace the flange g, formed on the
nut, which is free to revolve within the bush. The part h of the bush,
situated beyond the nut, fits upon the angular spindle, and is the means
whereby the revolution of the knob is communicated thereto. In applying
the spindle and knobs to a door lock, the moveable knob is removed by
revolving the nut by means of its washer. The spindle is then passed through
the door and lock, and the moveable knob drawn upon the spindle (by
revolving the washer) as far as requisite to suit the thickness of the door.
The washer is then to be secured from turning by a small pin or screw i
passing through it into the door.
In the arrangement shown at Fig. 2, the spindle is threaded as in the
previous arrangement, and a groove j is formed along one of its sides, into
which is fitted the drag piece k, let in flush with the side of the spindle, and
having a projection l, taking into a corresponding cavity formed in the bush
h (or in the knob), and a similar projection m inside of the nut, which nut
may be formed with the washer, by the revolution of which the knob is to
be drawn on to the spindle, as in the former instance, and the washer then
secured by a small screw or pin passing into the door, as before mentioned.
In metallic knobs the bushes may be dispensed with, and the corresponding
parts formed in the knob itself.
Having now described the nature of my said Invention, and in what
manner the same may be performed, I would have it understood that I do
not lay claim to any of the parts separately, neither do I confine myself to
the precise forms or details represented; but what I claim is, the combination

page_text: of parts herein described for the purpose of attaching or connecting knobs
to spindles.
In witness whereof, I, the said Charles William Ramié, have hereto
set my hand and seal, this Seventh day of November, in the year
of our Lord 1857.
