IMPROVEMENTS IN ATTACHING KNOBS TO SPINDLES
Year: 1879

page_text: LETTERS PATENT to Frederick Ryland, of West Bromwich, in the County of
Stafford, Manufacturer, for the Invention of "IMPROVEMENTS IN ATTACHING
KNOBS TO SPINDLES."
Sealed the 12th December 1879, and dated the 17th June 1879.
PROVISIONAL SPECIFICATION left by the said Frederick Ryland at the
Office of the Commissioners of Patents on the 17th June 1879.
FREDERICK RYLAND, of West Bromwich, in the County of Stafford, Manufacturer,
"IMPROVEMENTS IN ATTACHING KNOBS TO SPINDLES."
Referring to the annexed Drawings, Fig. 1 shews a plan of the underside of a
knob intended to be used with the form of rose shewn in plan, Fig. 2; Fig. 3 is an
clevation of the neck. (a) is the handle; (b), the neck formed with an undercut
cam projection (c); (d) is the spindle; (e), a tubular core of tin or thin sheet metal
round which the neck of the knob is cast; this core is employed for the purpose of
saving the labour of filing the casting to fit accurately the spindle. (f) is the rose
plate formed with a rib (g) in its inner periphery, corresponding to the form of the
neck at (b), so that passing the neck into the rose by fitting the projection (c) in the
space (h), and turning the handle round the projection (c) engages under the rib (g),
and the knob is prevented from being withdrawn from the rose plate. The part (g)
is formed also of thin sheet metal, and the plate cast round it to avoid the labour
of turning or filing the casting. The parts above described are applicable to furniture
used with mortice locks which employ similar parts on each side the lock, but for
rim locks when there is no rose plate on the lock side I use on that side a loose
collar shewn in plan, Fig. 4, and elevation, Fig. 5. This collar travels on the
screwed thread of the spindle so as to adjust it to the thickness of the door, and the
rib (7) keying into the groove (k) in the neck of the knob prevents the turning of
the knob upon the spindle. A pin fixed through the neck and rivetted upon each
side secures the parts together.

"IMPROVEMENTS IN ATTACHING KNOBS TO SPINDLES."
In the annexed Drawings Figure 1 shows a plan of the underside of a knob
intended to be used with the form of rose shewn in plan, Figure 2; Figure 3 is an
elevation of the neck. (a) is the handle; (b), the neck formed with an undercut
cam projection (c); (d) is the spindle; (e), a tubular core of tin or thin sheet metal
round which the neck of the knob is cast; this core is employed for the purpose of
saving the labour of filing the casting to fit accurately the spindle. (f) is the rose
plate formed with a rib (g) in its inner periphery corresponding to the form of the
neck at (b), so that passing the neck into the rose by fitting the projection (c) in
the space (h) and turning the handle round the projection (c) engages under the
rib (g), and the knob is prevented from being withdrawn from the rose plate. The
part (g) is formed also of thin sheet metal, and the plate cast round it to avoid the
fabour of turning or filing the casting.
Figure 6 represents a view of the entire arrangement.
The parts above described are applicable to furniture used with mortice locks
which employ similar parts on each side the lock, but for rim locks when there is
no rose plate on the lock side I use on that side a loose collar shewn in plan,
Figure 4, and elevation, Figure 5. This collar travels on the screwed thread of the
spindle so as to adjust it to the thickness of the door, and the rib (j) keying into
the groove (k) in the neck of the knob prevents the turning of the knob upon the
spindle. A pin fixed through the neck and spindle and rivetted upon each side
secures the other knob upon the spindle.
Having thus described the nature of my said Invention and the manner in which
the same is to be performed,-
-
I claim the improvements in attaching knobs to spindles, substantially as herein
more fully set forth and specified.
In witness whereof, I, the said Frederick Ryland, have hereunto set my
hand and seal, this Fifteenth day of December, in the year of our Lord One
thousand eight hundred and seventy nine.
FREDERICK RYLAND. (1..s.)
