PROVISIONAL SPECIFICATION.
Improvements in 'Connecting Door and other Knobs to their
Spindles.
We, ALFRED BROWN and HENRY CLARKE PRUCE, trading as A. Brown
and Company, of Smallbrook Street, in the City of Birmingham, Merchants and
Manufacturers, do hereby declare the nature of this invention to be as follows:-
Our invention relates to means for connecting door and other knobs to their
spindles and is an amplification of the invention described in the Specification
of a former Letters Patent granted to me and bearing date the 17th day of
February 1894 No. 3434, in which the foot of the neck of the knob takes or
is fitted within a sectional bush or bearing located within the middle part or' neck
of the rose.
!
According to our present invention, the sectional bush or bearing has an annular
groove or channel formed or sunken within its inside periphery, adapted to engage
upon a section flange at the foot end of the knob and a key flange of a screw box
or nut carried by the spindle.
In carrying out one form of our improvements, the foot end of the neck of the
knob (which has a square hole up its middle) is provided with a narrow collar,
having outstanding section flanges, which, with a portion of the collar, form, part
annular grooves and a key way between the flanges or opposite raised parts or
sides.
:
Taking upon the screwed spindle is a nut or screw box having at its inuer end, a
key part or flange of the same thickness, length and breadth as the key way
or sinking lying between the flanges of the foot end of the knob, and within which
keyway the said key flange fits and coincidently lies, thus forming, with the side
flanges on the knob foot end, a single and complete feather flange, which is embraced
by the sectional and jointed bush or bearing collar, whose annular groove freely
clips the said feather flange.
In making the connection between a loose knob and the spindle end, first rotate
the screw box upon the square and screw-edged spindle, up to the door, then slide
home the knob, which has the rose strung loosely, upon the neck, up to the screw
box, when the key flange of the one part takes into the key recess of the other.
Then pass the sectional bearing, when opened out, over and around the feather
flange and then close the bearing, so as to circumferentially embrace and clip the
said feather flange. Now pass the rose into position over the bearing and fix the
same to the door by small screws or other suitable means.
The sections of the clipping bearing may be jointed together by a link or they
may be carried by, and one of them jointedly connected to, a carrier ring to which
the other section is made fast.

page_text: Improvements in Connecting Door and other Knobs to their
Spindles.
We, ALFRED BROWN and HENRY CLARKE PRUCE, trading as A. Brown
and Company, of Smallbrook Street, in the City of Birmingham, Merchants and
Manufacturers, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
Our invention relates to means for connecting door and other knobs to their
spindles and is an amplification of the invention described in the Specification of a
former Letters Patent granted to me and bearing date the 17th day of February
1894 No. 3434, in which the foot of the neck of the knob takes or is fitted within
a sectional bush or bearing located within the middle part or neck of the rose.
According to our present invention, the sectional bush or bearing has an annular
groove or channel formed or sunken within its inside periphery, adapted to engage
upon a section flange at the foot end of the knob and a key flange of a screw box
or nut carried by the spindle.
In carrying out one form of our improvements, the foot end of the neck of the
kuob (which has a square hole up its middle) is provided with a narrow collar,
having outstanding section flanges, which, with a portion of the collar, form part
angular grooves and a key way between the flanges or opposite raised parts or
sides.
Taking upon the screwed spindle is a nut or screw box having at its inner end,
a key part or flange of the same thickness, length and breadth as the key way or
sinking lying between the flanges of the foot end of the knob, and within which
keyway the said key flange fits and coincidently lies, thus forming, with the side
flanges on the knob foot end, a single and complete feather flange, which is
embraced by the sectional and jointed bush or bearing collar, whose annular groove
freely clips the said feather flange.
In making the connection between a loose knob and the spindle end, first rotate
the screw box upon the square and screw-edged spindle up to the door, then slide
home the knob, which has the rose strung loosely upon the neck up to the screw
box, when the key flange of the one part takes into the key recess of the other.
Then pass the sectional bearing, when opened out, over and around the feather
flange and then close the bearing, so as to circumferentially embrace and clip the
said feather flange. Now pass the rose into position over the bearing and fix the
same to the door by small screws or other suitable means.
The sections of the clipping bearing may be jointed together by a link, or they
be carried by, and one of them jointedly connected to, a carrier plate ring to
which the other section is made fast.

Figure 1 of the accompanying drawings represents a set of door furniture fitted
in position and with the adjustable knob on the one side fitted with improvements
made according to our invention.
Figure 2 represents the parts of the said adjustable knob in the positions which
they assume prior to the knob taking over the end of a spindle and with the rose
and key-flanged screw box in section.
Figure 3 is a like view as Figure 2 but with the whole of the parts in elevation.
Figure 4 a cross section upon the dotted line a Figure 1, looking towards the
adjustable knob and with one of the halves of the sectional bearing collar opened.
Figure 5 represents a front elevation and an edge view of the sectional bearing
separately and Figure 6 represents like views of the key-flanged screw box.
Figure 7 is an elevation of the foot end of the adjustable knob.!

page_text: Figure 8 represents an elevation of the adjustable knob, showing the key flange-
of the screw box taking into the corresponding recess in the foot end of the
knob.
Figure 9 shows a modified form of sectional bearing, in which the sections of
the same are carried by, and one of them jointed to, a plate ring. Figure 10 is a.
section of the same.
In Figures 1 to 8 of the accompanying drawing, the same letters of reference.
indicate corresponding parts.
Taking upon the screwed end a¹, of a spindle a, is an inside screwed and adjust-
able knob b, with the foot end b', formed with a sectional collar flange 63, and with
the middle part, adjacent to the square eye or hole 6, recessed with a key way b*,.
corresponding to a key flange c', of a rotating screw box c, adjustable upon the
spindle. The section part , of this said box corresponds to the section part 6, of
the foot of the knob, whilst the section flange c', of the said screw box c, corre-
sponds to the cut-out 6 of the said flange b', so that on the knob being screwed on
to the end of the spindle and with the key way sinking 6, taking over the key
flange c', of the screw box, the collars and parts, being coincident, form a complete.
annular flange and a complete annular foot.
By now passing the sectional bearing d, (which constitutes a keep clip) over the
complete collar formed by the parts b, c, and then passing the rose e, over the
outer flange of the said bearing, the said bearing is closed over the foot end of
the knob and kept in position by passing of small screws e¹, through screw holes in
the same and thereby securing the same to a rose.
When clipped by the bearing the foot end of the knob with the collar, is free to.
rotate within the said bearing.
In Figures 9 and 10 one half part d' of the keep clip d is carried by a ring-
plate d', whilst the other half part d', is jointed to the said plate.
Figure 11 represents a further form of our invention. In this modification, a
segmental and split collar is employed on the foot of the knob and the rotating.
screw box separately.
Figure 12 represents the parts separately, a is the spindle, c is a screw box with
a complete circular and sectional flange e, which when brought up to the opposed
face of a like flange 6, at the foot end 6', of the knob (as represented in.
Figure 11) makes a complete flange and the said knob and screw box are prevented
from rotating one upon the other by the lugs c', upon the screw box taking into.
coincident sinkings , in the foot of the knob b, whilst the said parts are embraced
and held together by a clip collar or joiuted clip d, which is itself kept closed over
the complete collar by a rose e attached by small screws e¹, to a door.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what.
we claim is :-
First. In door furniture, securing a knob to its spindle by a part collar on the
gapped foot end of the knob fitting upon a like and part-collared opposed key end.
of a screw box or equivalent adjustable on the spindle, which parts, when fitting
one into or over the other, form a complete annular flange and foot end and are
locked together by a keep clip within which the said foot end is capable of freely
rotating, substantially as described and set forth in Figures 1 to 10.
Secondly. In door furniture, the general construction, arrangement and combi-
nation of the parts and the means for securing adjustable knobs to their spindles,
substantially as described and set forth in Figures to 9.
Thirdly. In door furniture, the modified form of sectional bearing or keep clip.
described and illustrated in Figure 10.
Fourthly. In door furniture, securing a knob to its spindle by a split or part.
circular collar on the foot end of the knob fitting up to a like split collared end
part of a screw box on the spindle, which, on the said collar parts coming together,
form a complete annular flange, and are kept from rotating upon one another by

page_text: lugs on the one taking into corresponding sinkings. in the other, and are locked
together laterally by a keep'clip within which the said annular flange is capable of
freely rotating, substantially as described and set forth in Figures 11 and 12.
Dated this 3rd day of December 1895.
