Year: 1856

page_text: LETTERS PATENT to Nathan Ager, of Upper Ebury Street, Pimlico, in
the County of Middlesex, Carpenter, for the Invention of "IMPROVEMENTS
IN CONNECTING SPINDLES OF LOCKS AND LATCHES WITH THEIR KNOBS AND
HANDLES."
Sealed the 24th June 1856, and dated the 4th February 1856.
PROVISIONAL SPECIFICATION left by the said Nathan Ager at the
Office of the Commissioners of Patents, with his Petition, on the 4th
February 1856.
I, NATHAN AGER, of Upper Ebury Street, Pimlico, in the County of Middlesex,
Carpenter, do hereby declare the nature of the Invention for "IMPROVEMENTS
IN CONNECTING SPINDLES OF LOCKS AND LATCHES WITH THEIR KNOBS AND HANDLES,"
to be as follows:-
The object of this Invention is to connect the spindles of doors or drawers
with their knobs or handles in a more simple and convenient manner, at the
same time facilitating the adjustment of the length of spindles to the varying
thickness of the doors and drawers. For this purpose each spindle is, by
preference, made with a square transverse section, and with a screw thread cut
on its angles, as has before been done. The knobs or handles are made with
hollow stems of a corresponding angular section with the spindle, and so that
the end of a spindle may pass into the stem of a knob or handle, but not turn
therein; and in order to attach a knob or handle to a spindle, a cylindrical
screw nut, with a flanch at one end is used, with a groove or recess in its outer
circumference; this screw nut, when separate from the knob or handle, screwз

page_text: freely on to the spindle, and when it has been adjusted to the proper position
thereon, the knob or handle is fixed to the screw nut by a screw passing through
the stem, so as to enter into the groove or recess in the outer surface of the
screw nut, by which the handle can turn freely on the screw nut, and at the
same time move round the spindle without changing the position of the screw
nut on the spindle.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Nathan Ager in the Great Seal Patent Office on the
4th August 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NATHAN
AGER, of Upper Ebury Street, Pimlico, in the County of Middlesex, Carpenter,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of February, in the year of our Lord
One thousand eight hundred and fifty-five, in the nineteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Nathan Ager, Her special licence that I, the said Nathan Ager, my executors,
administrators, and assigns, or such others as I, the said Nathan Ager, 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 "IMPROVEMENTS IN CONNECTING SPINDLES
OF LOCKS AND LATCHES WITH THEIR KNOBS AND HANDLES," upon the condition
(amongst others) that I, the said Nathan Ager, my executors or administra-
trators, 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 mouths
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Nathan Ager, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
My Invention consists of a peculiar combination of parts for connecting
spindles of locks and latches with their handles and knobs.

page_text: And in order that my Invention may be most fully understood and readily
carried into effect, I will proceed to describe the Drawing hereunto annexed,
which represents a spindle with one of its knobs or handles connected there-
with according to my Invention. The other handle or knob is fixed to the
spindle in any convenient manner, it only requiring that one of the ends of a
spindle should be formed with a view to adjustment. a is the spindle, which
is, by preference, made with a square transverse section, and with a screw
tbread cut at its angles, as has theretofore been done; b is the handle or knob,
in section, which is connected, according to my Invention, to the spindle a.
The knob or handle is made with a hollow stem, and, by preference, is bushed
with metal, as shown; the hollow or opening in which at 6' corresponds with
the section of the spindle, and so that the end of the spindle may pass into
the stem of the handle or knob, but not turned therein. c is a cylindrical
screw nut, having a flanch c¹ at one end, and also a groove or recess at c³ in
its circumference. This screw nut, when separate from the handle or knob,
screws freely on the spindle, and when it has been adjusted to the proper
position thereon, the knob or handle is fixed to the screw nut by a screw d
passing through the stem, so as to enter into the groove or recess in the outer
surface of the screw nut, by which mode of combining the parts, when the
handle or knob is turned it will by the part b¹ of its hollow stem turn the
spindle. The knob or handle 6 is retained correctly adjusted by the screw
nut c, and by the screw d, which passes through the stem of the handle or
knob, and enters the groove or recess c² formed in the screw nut.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I do not claim any
of the parts separately, nor do I confine myself to the forms or details of the
parts; but what I claim is, the mode herein described of combining apparatus
for connecting spindles of locks and latches with their knobs and handles.
In witness whereof, I, the said Nathan Ager, have hereunto set my hand
and seal, this Fourth day of August, in the year of our Lord One
thousand eight hundred and fifty-six.
NATHAN AGER. (L.S.)
Witness,
W. CARPMAEL, Jun.
