AN IMPROVEMENT IN FIXING ..THE SPINDLES OF DOOR LOCKS TO THEIR KNOBS
Year: 1855

page_text: LETTERS PATENT to Joseph Gibbons, of 345, Oxford Street, in the
County of Middlesex, for the Invention of "AN IMPROVEMENT IN FIXING
..THE SPINDLES OF DOOR LOCKS TO THEIR KNOBS."
PROVISIONAL SPECIFICATION left by the said Joseph Gibbons at the
Office of the Commissioners of Patents, with his Petition, on the 5th
February 1855.
I, JOSEPH GIBBONS, of 345, Oxford
Street; in the County of Middlesex,
Invention for "AN IMPROVEMENT IN
do hereby declare the nature of the
FIXING THE SPINDLES OF DOOR LOCKS TO THEIR KNOBS" to be as follows:-
This Invention has for its object an improvement in the construction of the
spindles of door locks, to facilitate the adjustment and fixing of the knobs
thereon. For this purpose, each spindle is formed with a slit or slot at one
or both ends, and on one side of the spindle is fixed a plate of steel or elastic
metal. The knobs, as heretofore, have screws, which pass into their stems
or shanks, and the inner end of each screw, on coming against the spring
near the end of the spring plate, bends out that end, so as to enlarge the
spindle. The passage in the stem or shank of the knob is inclined, or enlarged
inwards, to admit of the end of the spring plate being bent outwards; hence
the knob can be slided on its spindle into position, and be then fixed by
expanding the size "of the spindle either by a screw or other suitable
means.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPHI
GIBBONS, of 345, Oxford Street, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of February, in the year of our Lord' One
thousand eight hundred and fifty-five, in the eighteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Joseph Gibbons, Her special licence that I, the said Joseph Gibbons, my
executors, administrators, and assigns, or such others as I, the said Joseph
Gibbons, 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, excrcise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "AN IMPROVEMENT IN FIXING THE
SPINDLES OF DOOR LOCKS TO THEIR KNOBS," upon the condition (amongst others)
that I, the said Joseph Gibbons, by an instrument in writing under my hand
and seal, 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 Joseph Gibbons, 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):-
This Invention has for its object an improvement in the construction of the
spindles of door locks, to facilitate the adjustment and fixing of the knobs
thereon. For this purpose, each spindle is formed with a slit or slot at one
or both ends, and on one side of the spindle is fixed a plate of steel or elastic
metal. The knobs, as heretofore, have screws which pass into their stems or
shanks, and the inner end of each screw, on coming against the spring near
the end of the spring plate, bends out that end, so as to enlarge the spindle.
The passage in the stem or shank of the knob is inclined, or enlarged inwards,
to admit of the end of the spring plate being bent outwards; hence the knob
can be slided on its spindle into position, and be then fixed by expanding the
size of the spindle either by a screw or other suitable means,

page_text: Having thus described the nature of my said Invention, I will proceed to
describe more fully the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shows the section of two door knobs, with their spindle, and means
of fixing them thereto according to my Invention; Figure 2 shows three
views of a spindle constructed suitably for fixing door knobs thereto according
to my improvement; Figure 3 shows two views of the socket or interior part
of a knob when fixing door knobs to spindles according to my Invention.
I would remark that the Drawing shows an ordinary brass knob and a china
knob, but it will be evident that the improvement is equally applicable to
knobs made of wood, glass, or other substance, the improvement not being
in respect to the knob itself, but in the form of the spindle and socket for the
spindle which is within the knobs. a is the spindle, which is made with a slit
or slot a', at each or either end. To one side of the spindle is fixed a plate of
steel a², or other metal; this fixing may be done in any convenient manner, but
it is preferred to be done by a ring or hoop b, and screw c, as shown. On one
side the interior of the sockets d within the stems of the knobs are sunk, or
made concave, as shown. e, e, are screws, which passing through female screws
in the stems of the knobs, then pass through the slots or slits in the spindle,
and then end-press the plate a² outwards into a convex form, thus fixing the
knob to the spindle in such manner as not to slide thereon; and it will be
evident that the points of fixing of knobs to a spindle may be varied within
the limits of the slits or slots formed in the spindle, and it will also be evident
that in thus fixing a knob to a spindle the distance apart between the knobs
may be very accurately adjusted.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that what I claim is, the
combination of parts herein described.
In witness whereof, I, the said Joseph Gibbons, have hereunto set my
hand and seal, this Third day of August, in the year of our Lord
One thousand eight hundred and fifty-five.
Witness,
S. CARPMAEL.
JOSEPH GIBBONS. (L.S.)
