PROVISIONAL SPECIFICATION.
· Improvements in the Method of and Means for Attaching Door and
other Knobs and the like to their Spindles.
I, JAMES JOSEPH SUMNER of 132, Sherlock Street Birmingham in the County
of Warwick Brass Founder do hereby declare the nature of this invention to be as
follows:-
This invention relates to a method by which I am enabled to securely attach
door and other knobs, and the like to their spindles by dispensing with the usual
screw in the neck of the knob and also the drilling of the spindle for the reception
of such screw.
One method I employ consists in forming the neck of the knob with a projecting
rim or flange on its extreme end wherein the spindle is received, a semi-circular
metal collar, plate or washer is cut out so as to fit on the neck and obtain a
a bearing against the rim or flange, two or more holes are drilled in the washer,
also in the rose of the. knob, for screws, thus when the knob is fitted onto the
spindle, the rose is screwed to the door, the screws passing through the corre-
sponding holes in the washer which firmly secure the knob to the door, and
spindle, the washer preventing the knob from being pulled off, I may also form a
metal rim or collar upon the neck of the knob if required in order to hide the
washer from view through the aperture in the rose.
Or instead of a projecting rim or flange I may form a circular groove or recess
in the neck of the knob into which the metal washer fits, the same effect will be
gained, namely the prevention of the knob from pulling through the rose as in
both cases the washer being of sufficient width bears against a part of, or the
entire back of the rose and so retains the knob in position and securely fixes the
same thus rendering it practically impossible for it to become detached from its
spindle and so affording very effectual, means of attachment for the purpose or
purposes indicated herein.

Improvements in the Method of and Means for Attaching Door and
other Knobs and the like to their Spindles.
I, JAMES JOSEPH SUMNER of 132, Sherlock Street Birmingham in the County
of Warwick Brass Founder, 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, reference being had to the drawings accompanying
this Specification and to the figures and letters shewn thereon that is to say :-
My invention relates firstly to a method or to methods by which I am enabled to
securely and readily attach door and other knobs and the like to their spindles,

page_text: wherever they may be affixed by dispensing with the usual side set screw in the
neck of the knob and also the necessity for the drilling of the spindle as hereto-
fore for the reception of such screw.
'
Hitherto in the manufacture of china, porcelain wood, brass or metal door
furniture, it has been usual to mount the neck end of the knob with a brass or other
metal cap stamped, or cast, and to press the centre into the cavity in the
knob, wherein the spindle fits, the mount being rolled or turned over onto a bead
or pommel, formed upon the extreme end of the neck of the knob, the metal rose
which attaches the knob to the door has also had to be mounted by forming a
circular rim or mount of a separate piece of metal and connecting it to the rose
by means of a press or otherwise, the rim or mount being then rolled onto the first
named mount upon the neck.
Now I am enabled to dispense altogether with this double mounting process,
and one of the methods I employ consists in forming the neck of the knob without
any mount with a projecting circular rim or flange upon its extreme end wherein
the spindle is received, and when the rose is passed on, a semi-circular or other
suitably shaped back plate, collar, or washer, suitably cut out in its centre fits
partially around the neck and obtains a bearing against the rim or
flange and lies
within the rose, two or more holes are drilled in the back plate as also in the rose
corresponding thereto for screws to pass through both to attach the parts to the
door, thus when the knob is fitted onto the spindle which is made perfectly plain
without any drilling as hitherto, the knob is firmly secured.
Or instead of a projecting rim or flange I may form, and preferably so, a circular
groove, or recess, near the end of the neck into which the metal back plate fits,
by being passed into position horizontally behind the rose, and when secured by
screws in manner, before described, attaches the knob to the spindle, as in-both
cases the back plate or washer being of sufficient width fits into a part or the
entire back surface of the rose and being suitably shaped to correspond with the
interior of same.
The cavity in the neck that receives the plain spindle in either of the above
methods may be a plain square sided sinking without any interior metal lining, or
it may be so lined if required.
I will proceed to describe my invention fully with the assistance of the
drawings.
Figure 1 is a view of a knob formed with a groove or recess in the neck and-the
spindle in position.
Figure 2. an end view shewing the cavity for spindle.
Figure 3. a back view of a rose.
Figure 4 the metal back plate or washer. Figure 5 edge view of same.
Figure 6 a back view of the parts in position.
Figure 7. shews a knob having a bead or pommel upon the neck with mount
when desired.
Figure 8. is a front view of a rose for use with Figure 7. Figure 9. side view
of same.
Figure 10 alternative method of forming the knob with a circular flange or
projecting rim instead of a groove or recess.
Figure 11 a view of plain spindle.
Figure 12 shews a back view of a metal rose in connection with my improvements.
Figure 13 a side view of same.
Figure 14 shews position of rose when pushed up to the head of the knob when
adjusting the back plate.
I will firstly refer to the method of grooved neck named above.
A. is the circular groove or recess, formed in the neck B. of the knob and has a
plain. square spindle hole C. therein said knob may consist of wood, china,
porcelain, metal or other material usual for the purpose, in order to attach the
kuob the rose D. is passed onto the neck so that the groove A. projects slightly
within the rose D. the knob being placed on the spindle E. which is perfectly

page_text: plain being neither drilled in its sides or screw threaded at its ends, the back plate
collar or washer F. is passed into position horizontally in the groove A. and
obtains a firm hold around the greater portion of the neck the rose is then attached
to the door by screws through holes therein and the back plate G. G.
It will thus be seen that a very effectual and readily adjustable arrangement is
obtained for the purpose intended, whereby the usual side set screw in the neck or
side of the rose is dispensed with, moreover the parts when thus attached form a
much more secure method, with a far neater appearance, than hitherto adopted.
and in addition to the advantage of dispensing with the side set screw, the neck of
the knob with its grooved end being composed of one piece instead of the usual
practice of mounting the end of same, obviously much time, labour, and cost is
saved as also the metal mounts, and when the knobs are composed of china or
other breakable material, by being able to dispense with the mounting, the
constant breakage that has hitherto been the result of this process in a great
measure is avoided which is a most important feature.
It will be observed that the neck of my improved knob is longer than usual and
of a nearly straight formation, to allow the rose either mounted or not to pass
well up the neck whilst fitting in the retaining back plate, so that it can be easily
adjusted in position.
When china or wooden furniture is used with a mount upon the neck of the
knob I form the said neck B with a pommel or bead thereon H. which can be
mounted as shewn, or not, and which fits into the rose and thus assists in keeping
all tight.
When the rose is of china, or wood I may make it without any inner rim or
ledge so that the mounted neck fits into same and is adjusted as in the case of the
mounted long neck and groove, the centre of the rose having a raised bead or
collar L to allow of a perfect adjustment of the parts when different thicknesses
of rose may be used as they may vary somewhat in manufacture.
When the rose is made of brass or other metal, instead of the present method
where it has been usual to stamp or cast the same, and then to attach an inner
stamped or cast portion forming a mount upon same, by means of a press, thus
making two operations, I stamp or cast the said rose and its mount out of one
piece of metal at one operation and in any suitable manner Figures 12 and 13
thus a much better article is produced at less cost, and by my improved method of
stamping in one piece I may dispense with the inner flange or rim which enables
me to obtain a much larger aperture for the neck of the knob which can be of a
larger circumference and thus afford greater strength.
With reference to the arrangement of knob with a flange or rim shewn in
Figure 10 the mode of attachment and the means therefor will be precisely similar
to that already described in relation to Figure 1 and following figures in connection
therewith.
I do not limit myself to the precise details or arrangement of parts herein
specified as I may modify their formation without departing from my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what 1
claim is
Firstly. Attaching door knobs to their spindles in the manner and by any of the
means substantially as herein described.
Secondly. In connection with door and other knobs the formation of a groove
or recess around the neck of same, the semi-circular or other shaped back plate or
washer taking into the said groove said back plate lying within the rose all in
combination and for the purpose set forth.
Thirdly. In door knobs and their spindles the use of a plain sided spindle
fitting into a plain square cavity, lined with metal or not, in the neck of the knob
as set forth and described.
Fourthly. In door knobs forming the same with the neck longer and with the

page_text: grooved portion all in one piece and dispensing if desired with the mounting of
the said neck either at its end or elsewhere substantially in manner as set forth and
described.
Fifthly. In door knobs forming the same with a circular flange or projecting rim
upon the end (instead of a groove) as set forth and described.
Sixthly. In door furniture, forming a metal rose and its mount out of one piece
of metal in any suitable manner substantially as set forth and described.
Seventhly. The herein described general formation and arrangement of parts
in any of the forms or other similar acting means, and the methods or other similar
methods of carrying the same into effect for the purpose set forth.
