IMPROVEMENTS IN MEANS FOR ATTACHING KNOBS TO THEIR SPINDLES FOR DOOR FURNITURE, ALSO APPLICABLE FOR OTHER SIMILAR PURPOSES."
Year: 1879

page_text: LETTERS PATENT to William Squires Codner, of 10, Quadrant Road, Canon-
bury, in the County of Middlesex, for the Invention of "IMPROVEMENTS IN
MEANS FOR ATTACHING KNOBS TO THEIR SPINDLES FOR DOOR FURNITURE,
ALSO APPLICABLE FOR OTHER SIMILAR PURPOSES."
PROVISIONAL SPECIFICATION left by the said William Squires Codner at
the Office of the Commissioners of Patents on the 14th October 1879.
WILLIAM SQUIRES CODNER, of 10, Quadrant Road, Canonbury, in the County
of Middlesex. "IMPROVEMENTS IN MEANS FOR ATTACHING KNOBS TO THEIR
SPINDLES FOR DOOR FURNITURE, ALSO APPLICABLE FOR OTHER SIMILAR
PURPOSES."
This Invention relates to means of or device for attaching or securing the knobs
or handles of lock or door furniture to their spindles, the object being to provide a
device of simple yet effective construction, and that from its cheapness may be
applied either to cheap or costly fittings.
In carrying the Invention into practice I employ the ordinary square spindle
with screw threaded edges, and apply a fly nut thereto, said fly nut having a milled
edged flange and a socket piece screw threaded externally, said external screw
thread being reverse to that upon the spindle and the internal thread of the said
fly nut. The interior opening of the knob or handle is for a certain distance
threaded to receive the socket piece of the fly nut, and terminates in a square hole
fitting the square spindle; thus there is the combination of the right and left
handed fly nut engaging with the reverse threaded spindle and internal screw
thread of the knob, and the projection of the square spindle into the terminating
square hole of the knob or handle, which when the fly nut is adjusted to its required
position on the spindle and then turned will draw the knob or handle along the
spindle and at the same time advance the fly nut into its position against the
68 rose or door, when the locking of the parts will be effectual until the fly nut is
again turned to release the parts. The square hole of the handle fitting the spindle
prevents any turning of the fittings on the spindle by the ordinary turning action
of opening and closing the door. It will be obvious that the device is applicable
for attaching or jointing parts together in other appliances than door furniture
where two parts have to be connected under similar conditions.
The great advantage of this apparatus is its adaptability to existing furniture,
and the facility afforded for its adaptation by reason of its simplicity and fewness
of parts.

the said William Squires Codner in the Great Seal Patent Office on the 14th
April 1880.
WILLIAM SQUIRES CODNER, of 10, Quadrant Road, Canonbury, in the County
of Middlesex. "IMPROVEMENTS IN MEANS FOR ATTACHING KNOBS TO THEIR
SPINDLES FOR DOOR FURNITURE, ALSO APPLICABLE FOR OTHER SIMILAR
PURPOSES."
This Invention relates to means of or device for attaching or securing the knobs
or handles of lock or door furniture to their spindles, the object being to provide a
device of simple yet effective construction, and that from its cheapness may be
applied either to cheap or costly fittings.
In order that the said Invention may be well understood I have hereunto annexed
a Sheet of Drawings illustrative thereof, wherein Fig. 1 represents the two knobs
of a door spindle fitted acccording to this Invention, although one knob might be
rigidly affixed to the spindle.
Fig. 2 represents the double screwed fly nut in position upon the screwed spindle
ready for the handle being advanced upon the said fly nut preparatorily to said nut
being screwed up, as represented in Fig. 1.
Figs. 3 and 3 represent the handle in longitudinal section and under view.
Figs. 4 and 4a represent the fly nut in longitudinal section and end view.
Fig. 5 represents modification of the double screwed fly nut formed as a screw
cap for the shank of the handle.
In carrying the Invention into practice I employ the ordinary square spindle A
with screw threaded edges, and apply a fly nut B thereto, said fly nut having a
milled edge flange C and a socket piece D screw threaded externally or internally,
as represented at D' in Fig. 5, said external or internal screw thread being reverse
to that upon the spindle and the internal thread E on the neck of the said fly nut.
The interior opening of the knob or handle or externally thereof is for a certain
distance at F, or externally at F¹, threaded to receive the socket piece D or D' of
the fly nut, and terminates in a square hole G fitting the square spindle. Thus
there is the combination of the right and left handed fly nut B engaging with the
reverse threaded spindle and internal or external screw thread F or F of the knob,
and the projection of the square spindle into the terminating square hole G of the
knob or handle, which when the fly nut B is adjusted to its required position on
the spindle A and then turned will draw the knob or handle along the spindle A,
and at same time advance the fly nut B into its position against the "rose or
door H, when the locking of the parts will be effectual until the fly nut is again
turned to release the parts. The square hole of the handle fitting the spindle
prevents any turning of the fittings on the spindle by the ordinary turning action
of opening and closing the door. It will be obvious that the device is applicable
for attaching or jointing parts together in other appliances than door furniture
where two parts have to be connected under similar conditions.
"
The great advantage of this apparatus is its adaptability to existing furniture,
and the facility afforded for its adaptation by reason of its simplicity and fewness
of parts.
Having now described the nature and particulars of the said Invention, I
claim,―
The improvements in the means for attaching knobs to their spindles for door

page_text: furniture, also applicable for other similar purposes where two parts have to be
connected together under similar conditions, as herein specified in reference to and
shown by the Drawings, Figs. 1 to 4ª and Fig. 5.
In witness whereof, I, the said William Squires Codner, have hereunto set my
hand and seal, this Twelth day of April, in the year of our Lord One
thousand eight hundred and eighty.
WILLIAM SQUIRES CODNER. (L.S.)
