IMPROVEMENTS IN MEANS FOR ADJUSTING AND FIXING KNOBS OR HANDLES ON THE SPINDLES OF MORTISE AND OTHER LOCKS OR FASTENINGS
Year: 1874

page_text: LETTERS PATENT to John Harrington, of Ryde, Isle of Wight,
Gentleman, for the Invention of "IMPROVEMENTS IN MEANS FOR
ADJUSTING AND FIXING KNOBS OR HANDLES ON THE SPINDLES OF MORTISE AND
OTHER LOCKS OR FASTENINGS."
Sealed the 1st December 1874, and dated the 10th June 1874.
PROVISIONAL SPECIFICATION left by the said John Harrington at the
Office of the Commissioners of Patents, with his Petition, on the
10th June 1874.
I, JOHN HARRINGTON, of Ryde, Isle of Wight, Gentleman, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MEANS
FOR ADJUSTING AND FIXING KNOBS OR HANDLES ON THE SPINDLES OF MORTISE AND
OTHER LOCKS OR FASTENINGS," to be as follows:-
The Invention has for its object improvements in means for adjusting
and fixing knobs or handles on the spindles of mortise and other locks or
fastenings. For this purpose the spindle is formed square as usual,
the corners of which are cut into portions of a screw to enable the knob

page_text: which is correspondingly tapped to be screwed thereon. The rose is
formed with a square hole therein to fit the spindle, by which means it
can be readily slidden on to the spindle but will not turn thereon. The
rose has fixed on the back thereof a spring which carries two studs;
these studs pass into holes formed through the rose, and one of them
projects to a short distance beyond it. Corresponding holes are formed
in the knob or handle so that when the latter is screwed up the pro-
jecting stud can enter any one of such holes. Thus by holding back the
studs the knob or handle may be screwed on the spindle until a proper
adjustment is obtained, then by allowing the projecting stud to spring
forward into one or other of the holes in the knob or handle the latter is
prevented turning without the rose, and consequently on turning the
knob or handle the rose and spindle are also turned with it. The knob
or handle cannot be turned on the spindle until by the aid of a bradawl
or other similar tool the spring is acted upon to release the projecting
stud from the hole in the knob or handle.

If desired the second stud may be also caused to project and be
furnished with an enlarged head to enable it to be acted upon by the
finger; or it may be made flush with the surface of the rose; or it may
be dispensed with altogether, in which latter case the spring can be
directly acted upon by a tool passed through a hole in the rose.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Harrington in the Great Seal Patent Office
on the 10th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HARRINGTON, of Ryde, Isle of Wight, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of June, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Harrington, Her special license
that I, the said John Harrington, my executors, administrators, and
assigns, or such others as I, the said John Harrington, my executors,
administrators, and assigns, should at any time agree with, and no

page_text: 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
MEANS FOR ADJUSTING AND FIXING KNOBS OR HANDLES ON THE SPINDLES OF
MORTISE AND OTHER LOCKS OR FASTENINGS," upon the condition (amongst
others) that I, the said John Harrington, 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

page_text: If desired the second stud may be also caused to project and be
furnished with an enlarged head to enable it to be acted upon by the
finger; or it may be made flush with the surface of the rose; or it may
be dispensed with altogether, in which latter case the spring can be
1.

Figure 1 is a sectional view showing a lock spindle with a knob or
handle adjusted and fixed thereon according to my Invention; Figure 2
is a view of the inner end of the knob or handle separately; and Figures
3 and 4 are back and front views of the rose separately.
a is the spindle, on one end of which the knob or handle is per-
manently fixed in any suitable manner; this spindle is formed square as
usual, the corners being cut into portions of a screw to enable the
knob c to be screwed thereon; the rose d is formed with a square hole d¹
therein to fit the spindle a, by which means it can be readily slidden on
to the spindle but will not turn thereon; the rose d has fixed on the back
thereof a spring d² consisting of a flat piece of metal rivetted or other-
wise fixed to the rose at d³; this spring d² carries two studs d', d³, which
pass into holes formed through the rose d, and the stud d' projects to a
short distance beyond the surface of the rose d; corresponding holes c¹
are formed in the knob or handle c, so that when the latter is screwed
up the projecting stud d' can enter any one of such holes. Thus by
holding back the studs d', d, by means of a bradawl or other similar
tool acting against the stud d³, the knob or handle c may be screwed on
the spindle until a proper adjustment is obtained; then by allowing the
projecting stud d' to spring forward into one or other of the holes c¹ in
the knob or handle c, the latter is prevented turning without the rose d,
and consequently on turning the knob or handle c the rose d and
spindle a are also turned with it.
It is evident that the knob or handle c cannot be turned on the
spindle a until the spring d² is acted upon to release the projecting
stud from a hole c' in the knob or handle. Or the stud or studs may
be rivetted to a disc of metal, not being of itself a spring, and the disc

page_text: of metal may be kept in position by a thick washer or flat ring of india-
rubber, or by a spring of other description acting thereon.
If desired the stud d³ may be also caused to project, and may be
furnished with an enlarged head to enable it to be acted upon by the
finger, or it may be made flush with the surface of the rose d, or
dispensed with altogether, in which latter case the spring d² can be
directly acted upon by a tool passed through a hole in the rose d.
At Figures 5, 6, 7, 8, and 9 I have shewn various views of a slight
variation from the arrangement above described, similar parts being
marked with similar letters of reference to those employed in the
previous Figures. In this latter arrangement instead of the rose & being
of a similar form to that above described, and to the rose ordinarily
employed, it is made to fit a recess formed in the rose d*, and the spring
or disc d² has fixed thereto two studs d', both of which pass into holes c¹
in the handle c, the stud d³ being dispensed with and the spring or
disc d² being acted upon directly by any convenient instrument applied
thereto at the part d. By this latter arrangement the rose d* may be
screwed to the door in the usual manner, whilst the rose d acts as before
described and turns with the spindle a.
Having thus described the nature of my said Invention, and the mode
in which I carry the same into effect, I would have it understood that I
do not claim the forming the spindle a square and with portions of a
screw cut thereon, as such has before been employed with other devices
for securing the handle thereon; but what I claim as my Invention is,
the employment in combination with a square spindle screwed at its
angles of a rose & carrying a spring or disc of metal d² having studs d', d³,
acting in combination with holes c' in the knob or handle c, in manner
and for the purpose substantially as herein shown and described.
In witness whereof, I, the said John Harrington, have hereunto
set my hand and seal, this Seventh day of December, in the
vear of our Lord One thousand eight hundred and seventy-four.
