PROVISIONAL SPECIFICATION.
Improvements in Connecting Door and like 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, Manufacturers, do
hereby declare the nature of this invention to be as follows:-
This invention has relation to adjustable means for securing door and like knobs
to their spindles, and has for one of its objects, a simple and efficient means of
connection, whereby rattling is prevented and the working loose of the parts is
obviated, and for another of its objects, the taking of the strain on the turning of a
knob from off both the spindle and the connecting screw.
The essential feature of our invention consists in the employment of a loose split
and fitted bearing for the foot end of a knob to work within.
In carrying out one form of our invention in connection with the "Duce" type
of furniture, we take an angle-screwed and slotted spindle and a knob screwed up
its middle to take upon the said spindle, and with a screwed hole through its neck
adjacent to a foot collar or flange, which latter takes and works within the bearing
race of a cup-shaped bush or sleeve made in two or more transverse sections, held
or clamped together by the rose.
Thus the bearing consists of a split or sectional bush made cup-wise, and with
the fore part centrally pierced and having an undercut channel or race, of the
sectional shape of the flange of the knob, whilst the spindle of the knob passes
through the said central piercing.
The outside fore part of the bearing is tapered or coned or increases in size from
front to rear and upon which the inside boundary edge of the hole in the rose
takes, and by means of which the split or segmental parts of the bearing are held
closely together, forming a complete bearing for the foot of a knob to turn within.
Assuming that the knob has been screwed upon its spindle and the keep screw
passed through the hole in the neck and that its foot collar has been brought up to
a distance from the door equal to the distance between the race or channel of the
bearing and its back edge and assuming that the bearing. is composed of two or
more sectional parts, and that the rose is brought back onto the neck of the knob,
first pass one half of the bearing home with the race or channel taking over one.
half of the foot flange of the knob and with the edge of its cupped or hollow back
coming into juxtaposition with the door. Then pass the second sectional half
home in manner alike unto the first, and push the rose back from off the neck
towards the door, which, closes the sectional parts of the bearing, and when the
rose is fixed by small screws to the door, the said bearing is held in its assigned
position by the said rose.
Now that the foot flange of the knob works within a supplementary bearing
located between the rose and the back of the door, all strain occasioned by the
turning and twisting of the knob is taken from off the spindle and the keep screw
securing the knob to the spindle.
The bearing may be made to cover or hood over the head of the keep screw and
thereby prevent it from rising.
We wish it to be understood that our invention is applicable to varying types of
door furniture other than that described.
In a further form of our invention, the sectional parts of the bearing may be
jointedly connected to a carrying plate or washer.
Thus, a thin disc washer is taken with a hole through its middle and with the

page_text: sectional bearing parts jointed to it, so that the said parts are capable of opening
out and closing upon the spindle whilst being carried by the plates, and by this,
the said sectional parts are kept together and prevented from becoming lost.
As a still further form, we make the said sectional parts from sheet metal by
taking a pierced disc and raising the same cupwise, and then turning the front
edges of the cup over so as to form an undercut race as referred to in the first
arrangement.
The said sections may be made separately or they may be made in one piece
which is then divided by being transversely cut or sawn.
As still another form of our invention, the said sectional parts may be attachedly
connected to their carrier washer by headed studs on the said sectional parts taking
into long cross piercings in the said washer, so as to admit of the said sectional
parts opening out for taking over the spindle, whilst at the same time being kept
together.
As a still further form of our invention, we may provide each of the said
sectional bearings with a flange screwed upon its periphery for receiving the screw
of an inner-mounted china or wood rose, or the china or wood rose may take direct
upon the said peripheries or screwed parts.
In such a case, we propose that the split bearing should be secured to a door by
small screws passing through screw holes directed through the flanges as aforesaid.
Thus, assuming that the sectional parts of the bearings have upright flanges
which are screwed on their edges, first pass the sections over the spindle, then
bring the same together and affix them in position and to a door by small screws.
Now screw the rose upon the edge of the sectional bearings, which bearings are
kept together thereby.
As still another form of our invention, we connect the sections together directly
by jointing or hinging them one to another.
The whole of the forms described may be made from sheet metal and can be
applied to and used with practically all types of spindles now in use.

Improvements in Connecting Door and like 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, 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 :-
This invention has relation to adjustable means for securing door and like knobs
to their spindles, and has for one of its objects, a simple and efficient means of
connection whereby rattling is prevented and the working loose of the parts is
obviated, and for another of its objects, the taking of the strain on the turning of a
knob from off both the spindle and the connecting screw.
The essential feature of our invention consists in the employment of a loose split
and fitted bearing for the foot end of a knob to work within.
In carrying out one form of our invention in connection with the "Duce" type
of furniture, we take an angle-screwed and slotted spindle, and a knob screwed up
its middle to take upon the said spindle. and with a screwed hole through its neck

page_text: adjacent to a foot collar or flange, which latter takes and works within the bearing
race of a cup-shaped bush or sleeve, made in two or more transverse sections, held
or clamped together by the rose.
Thus the bearing consists of a split or sectional bush, made cup-wise and with
the fore part centrally pierced and having an undercut channel or race, of the
sectional shape of the flange of the knob, whilst the spindle of the knob passes
through the said central piercing.
The outside fore part of the bearing is tapered or coned, or increases in size
from front to rear and upon which the inside boundary edge of the hole in the rose
takes, and by means of which the split or segmental parts of the bearing are held
closely together, forming a complete bearing for the foot of a knob to turn within.
Figure 1 of the accompanying drawings represents a vertical section, partly in
elevation, of a set of door furniture, or a spindle provided with fixed and adjustable
knobs, the latter provided with a loose and split bearing for the foot end of the
knob to turn and work within.
Figure 2 represents a transverse section of Figure 1, upon the dotted lines ―x,
looking towards the rose, a portion of which is broken away sufficient to show a
portion of the periphery of the said split or segmental bearing.
Figure 3 represents a section upon the dotted lines A Figure 1.
Figure 4 represents a vertical section of the bearing separately, showing the
tapered front part and the transverse split for allowing the same to be opened out,
the all-through piercing and the undercut channel or race, wherein the annular
collar or feather at the foot end of the neck of the knob takes.
Figure 5 is a front elevation of Figure 4 and Figure 6 is a side view thereof.
Figure 7 represents the split bearing opened out.
Figure 8 represents a section of the rose and Figure 9 an elevation of the knob.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
a is an adjustable knob, inside screwed for taking upon an outside screwed and
slotted spindle b, whose other end has a fixed knob c. a is the neck of the
adjustable knob having an annular shoulder or web a², near its foot or inner end a³,
adapted to take and work within an undercut race d', of a divided or split knob
bearing d, having an all-through hole d², through its middle, a back collar d³, and
a taper or curved front part d, with the part of larger diameter equal in size to
the diameter of the middle piercing or hole e², of the loose rose e, which is affixed
in position and to the door, by small screws e, taking through holes in its
flange.
The two half parts of the said knob foot end bearing are connected and jointed
together by a link do, having pins do, taking through holes in the ends of the link
and in lugs, formed upon two of the adjacent ends of the sections.
Assuming that the knob has been screwed upon its spindle and the keep screw g,
passed through the hole in the neck and that its foot collar has been brought up to
a distance from the door equal to the distance between the race or channel of the
bearing and its back edge, and assuming that the bearing is composed of two
sectional parts, and that the rose is threaded or brought back onto the neck of the
knob, then pass the bearing, when open, around the foot end of the knob and close
the same upon the said foot end and collar of the knob with its open back and flange
coming into juxtaposition with the door.
Then bring the rose back to the door, with its middle piercing coming over the
outer peripheries of the parts of the bearing which are drawn together and clamped
by the rose.
Now that the foot flange of the knob works within a supplementary bearing
located between the rose and the back of the door, all strain occasioned by the
turning and twisting of the knob is taken from off the spindle and the keep screw
securing the knob to the spindle.
The bearing is made to cover or hood over the head of the keep screw and
thereby prevent it from rising.

page_text: We wish it to be understood that our invention is applicable to varying types of
door furniture other than that described.
In a further form of our invention, the sectional parts of the bearing may be
jointedly connected to a carrying plate or washer, instead of being secured together
by a link.
Thus, a thin disc washer is taken with a hole through its middle and with the
sectional bearing parts jointed to it, so that the said parts are capable of opening
out and closing upon the spindle whilst being carried by the plates, and by
this, the said sectional parts are kept together and prevented from becoming lost.
Figure 10 represents a front elevation of such an arrangement, and Figure 11
represents a back view of the same, but with the divided half parts opened out,
whilst Figure 12 is a section of Figure 10.
d is a bearing or bush, with the half parts jointed by pins do, to a carrier
ring or washer 8, having a middle clearance sufficient to pass over the foot end
collar of the knob.
Figure 13 represents a front elevation of a modification of the first-named
bearing or bush, in which, instead of having a solid link, a slotted one is
employed.
d is the knob foot end bearing or bush, with the sections or half parts
connected together by a link d³, by pins do, taking through lug extensions of
the said half parts.
Instead of the sections of the bearing being connected together by links or
the like, they may be made loose.
As a still further form we may make the said sectional parts from sheet metal
by taking a pierced disc and raising the same cupwise, and then turning the front
edges of the cup over so as to form an undercut race as referred to in the first
arrangement.
The said sections may be made separately or they may be made in one piece
which is then divided by being transversely cut or sawn.
Figure 15 represents in front elevation, and in vertical section a knob foot end
bearing made from sheet metal and according to my invention.
Figure 16 represents a front and edge view of the blank from which the said
bearing is made.
Figure 17 represents a section and Figure 18 a front view of the cup formed
by the first process in the making of the bearing and the ears or lugs for connecting
the two halves of the bearing together by a link or otherwise.
Thus I take a blank of metal Figure 16 and raise the same into a cup d,
Figure 17, and cut or pierce from the collar d³, cars or lugs d. These said lugs
or ears are then turned back and the remaining part of the said collar closed
forward, leaving an inner race d', between the inside surfaces of the presented
walls.
-The cup is then divided upon the dotted lines B Figure 17, and the half parts
united by a link d', see Figure 15.
As still another form of our invention, we connect the sections together directly
by jointing or hinging them one to another. As represented in Figure 19 or if
Decessary they may be made separate and without any connection, as in Figure 20.
Figure 21 represents a section of a split bearing screwed upon its periphery, so
that an inner screwed mount of a china or wood rose or the inner screwed hole of a
metal rose may take upon it and hold the segments together.
The whole of the forms described may be made from sheet metal, and can be
applied to and used with practically all types of spindles now in use.
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, employing in connection with the knob and rose, a

page_text: loose and split or sectional bearing or bush, for the foot end of the knob to work
within, substantially as, and for the purpose as, described and set forth.
Secondly. In the foot-end bearings of door knobs, connecting together or
carrying the sections of the same, either by a link, or by a ring or carrier,
substantially as described and set forth in Figures 1, 2, 3, 4, 5, 6, 7, 10, 11, 12, 13,
14, 15 and 19.
Thirdly. Making the foot end bearings of door knobs from sheet metal, by the
way substantially as described and set forth in Figures 15 to 18.
