PROVISIONAL SPECIFICATION.
Improvements in and relating to the Manufacture of Door and other
Knobs, Cupboard Turns, and the like.
I, JAMES JOSEPH SUMNER of 132, Sherlock Street Birmingham in the County
of Warwick Brassfounder, do hereby declare the nature of this invention to be as
follows:-
This invention relates to certain means whereby I am enabled to dispense
altogether with the ordinary process known as mounting the neck of the knob.
wherein the spindle is received.
Referring firstly to door knobs and rose furniture I form the neck perfectly
straight, or nearly so, and plain at its extreme end, that is to say without any
mount thereon, the rose is then passed into the neck, said rose when of metal. is
stamped or pressed out of one piece with a collar or rim at right angles thereto and
having an inner rim or flange encircling same, a metallic cap or disc having a
square hollow or tubular inwardly projecting piece attached thereto is now placed
on the end of the knob, the tubular piece being firmly embedded in the neck and
attached within same by lead or other suitable means, both the inner walls of the
knob and the outside of the tubular piece are roughened, nicked, or screw threaded
for the lead to obtain a good hold, and so prevent the parts from pulling out, the
sides of this metal cap fit over and bear onto the inner rim of the rose and thus
prevents the knob from coming off, when a disc is used it will be larger than end of
neck so as to fit against the said inner rim, the spindle is received by the square or
other hole in the tubular piece as in the usual manner, thus the knob although not
mounted, as usually understood by the term, has the appearance of being so, the
rose when screwed to the door taking the place of and acting as the mount as the
collar upon same fits closely to the neck and so gives a good finish.
For other descriptions of knobs used in connection with mortice, rim and such
like furniture, instead of the usual method of mounting the neck, I form the knob
as before described with a straight neck and I use a metallic cap having the
tubular portion which receives the spindle (attached therein) projecting inwardly
into the neck and attached within same by lead being run in or other suitable
means as before described, the sides of the cap are turned over the neck by a press or
other suitable method and fit closely around same and when polished or burnished
the knob will appear as if fully mounted.
The spindle may when desired be permanently attached to the knob at its' one
end by lead or other means to fix same after it has been passed through the
metallic cap, a slot or aperture being made in the cap or its face for the lead to be
run in, in this case the cap may not require the tubular piece for insertion into the
neck as the spindle itself will be permanently attached thereto, as set forth..
Referring to the cupboard turns. By the present method of attaching the
spindle to the knob it is usual to rivet or otherwise attach a stamped or cast cup to
the spindle and then to mount the cup onto a neck or bead on the knob. By my
method I form the neck portion perfectly straight as in the door knobs without
any mount whatsoever and I attach the spindle thereto permanently by means of
leading or otherwise securing same within the neck without the necessity of
any mounting of the knob or spindle end. In order to attach the cupboard turn,
the knob and spindle is passed through a suitable rose, either metal or china which

page_text: is attached to the door, the spindle having been passed through the door the usual
tongue piece or catch is screwed onto same and secured by a set screw and the
parts are thus securely adjusted in position. The rose in no way assists to retain
the parts but is merely for ornamentation whereby the appearance of a mounted
knob is given, the rose becoming the mount and whilst fitting closely round the
neck allows the knob and spindle to freely turn therein.
Or the knob and its spindle may be used without the rose when desired, in
which case I pass the spindle or stem end through a metal cup having a square
hole to receive same, the spindle is extended somewhat in length so that it may be
leaded in or otherwise secured to the knob, thus the appearance of a fully mounted
knob is given when used in combination with metal or chiua roses.
By the above described improvements it will be readily understood that the
object of my invention is to entirely do away with the ordinary method of
mounting the knobs or spindles and to produce effective means as a substitute
therefor, thus cheapening the cost of production and providing a better article, and
thus preventing or minimising the breakage that is liable to occur when mounting
china and such like knobs as hitherto.

Improvements in and relating to the Manufacture of Door and other
Knobs, Cupboard Turns, and the like.
I, JAMES JOSEPH SUMNER of 132, Sherlock Street Birmingham in the County
of Warwick Brassfounder, 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 :-
My invention relates to certain means whereby I am enabled to dispense
altogether with the ordinary process known as mounting the neck of the knob
wherein the spindle is received.
In the accompanying drawings I have illustrated in the several figures my
improvements, similar letters of reference indicate similar parts.
•
Fig. 1 represents in elevation a straight necked knob which is one of the forms in
which I carry out my invention and apply the same.
Fig. 2. represents in plan a front view of the rose and cap or disc. Fig. 3 a plan
of the back of the rose shewing the cap or disc in connection therewith.
Fig. 4 represents the cap or disc, Fig. 5 shews the knob and rose attached.
Fig. 6 is a side view of the cap or disc.
Fig. 7. represents in sectional view the rose with the cap or disc.
Fig. 8. represents in elevation an alternative method of knob having a bead
thereon.
Fig. 9. is a part sectional view of this form of knob shewing the cap or disc and
spindle in position.
Fig. 10. represents another modification of my invention for use with mortice
furniture and the like whereby I may dispense with the rose using a metallic cap
in the place thereof.
Figs. 11 and 12. are front and back views in plan of the cap.
Fig. 13. a side view of same.
Fig. 14. is a sectional elevation shewing the parts.
Fig. 15. shews an elevation of a cupboard turn knob.
Fig. 16. the spindle and disc in connection therewith.
Fig. 17. the disc alone.

page_text: Fig. 18. represents a front plan view of the rose for cupboard turns.
Fig. 19. a back plan of same with spindle and tongue piece.
Fig. 20. a side elevation of rose.
Fig. 21. shews the cupboard turn complete.
Fig. 22. is a sectional elevation shewing an alternative method of cap instead of
a rose.
Fig. 23. side view of cap.
Fig. 24. is a plan view of same.
Referring firstly to door knobs and rose furniture the one method I adopt is to
form the neck A. of the knob perfectly straight or nearly so and plain at its
extreme end that is to say without any mount thereon, the rose B. is then passed
onto the neck A. said rose when of metal is stamped or pressed out of one piece
with a collar or rim C. at right angles thereto and having an inner rim or flange D.
encircling same, a metallic or other cap or disc E. having a square hollow or
tubular inwardly projecting piece F. integral therewith is now placed within the
rose B. and the disc E. obtains a bearing upon the inner rim D. the tubular
piece F. being firmly embedded in the neck A. of the knob and securely attached
within same by lead run in hot or other suitable means, both the inner walls of the
neck A. and the outside of the tubular piece F. are roughened, nicked out, jagged
or screw threaded for the lead in its liquid state to obtain a good hold and so
prevent the parts from pulling out, thus a permanent attachment is afforded, the
disc E. fitting upon the internal rim D. of the rose as stated retains the knob
in place, the spindle G. is received in the square or other aperture in the tubular
piece F.
Thus the knob although not mounted as usually understood by the term has the
appearance of being so, the rose B. when screwed to the door taking the place of
and acting as the mount as the collar or rim C. upon the same fits closely around
the neck and so gives a good finish.
The projecting tubular piece F. has holes F¹ in the sides to allow of the lead
being run in by any suitable means for instance what is known as a dish is placed
in the aperture of the tubular piece F in connection with the holes F¹ for the
purpose of guiding the lead into and through same, any superfluous lead protruding
through the holes into the interior sides of the tubular piece is cut off'flush with a
cutter so that the spindle end can fit in.
It will be obvious that the knob and furniture may be of metal, wood, china,
porcelain, or glass and that my improved means of attachment will equally well
apply.
Referring to the alternative form of knob shewn in Figs. 8 and 9. I may
construct the knob with a bead H. upon the neck, and preferably so, in this case
the collar or rim C. fits close up to and abuts against same being attached in
precisely the same manner to that already described, the bead acting as a ineans
for preventing any possibility of the sharp edge of the collar or rim C. injuring the
hand or cutting a glove.
By either of these methods of construction it will be readily seen that no set
screw is required in the side of the neck to retain the knob on the spindle.
For other descriptions of knobs used in connection with mortice rim and such
like furniture instead of the usual method of mounting the neck I either form the
same as before described straight or nearly so or with the bead H. thereon
(preferably the latter) as in Figs. 10 and 14. and I use a metallic cap I. having the
tubular portion J. which receives the spindle projecting inwardly into the neck
and attached within same by lead being run in or other suitable means as set forth,
the sides of the cap are turned over the neck at the top by a press or other method
and abuts against the bead so that the cap fits closely around the neck, in this case
a side set screw K. will be used which takes into slots or holes in the spindle as in the
ordinary manner. The spindle may when desired be permanently attached to the
knob at its one end by leading or by a set screw to fix it after it has been passed
through the metallic cap I.

page_text: Thus when the cap is polished or burnished the knob will have the appearance.
as if fully mounted and the parts are securely attached.
Referring to the cupboard turns illustrated in Fig. 15 and the following figures.
By the present method of attaching the spindle to the knob it is usual to rivet or
otherwise attach a stamped or cast cup or cap to the spindle and then to mount the
cup onto the neck or bead thereon of the knob, by one of my methods I may form
the neck perfectly straight as in the door knobs and without any mount whatsoever
and I attach the spindle therein permanently by means of leading or otherwise
securing the same without the necessity of any mounting of the knob or spindle.
Either when a straight neck or one with a bead thereon is used a metallic disc or
back plate a. is placed on the end of the spindle b. as in Fig. 16 which spindle end may
be swelled out as shewn so as to retain the disc thereon and jagged to obtain a good
hold in the lead, the spindle and disc are then passed through the rose c. formed
as before described either of metal, wood or china etc. the disc fitting into the
inner rim d. of the same and giving a good finish, the spindle is firmly attached
within the knob by lead run in through a slot e. and hole e¹ in the spindle and disc
which hole e' acts as a guide in pouring in the lead.
When other than a metal rose is used I can dispense with the disc or back plate
as it may not be needed merely using the metallic cap.
The cupboard turn is attached to the door by passing the spindle through and
screwing on the usual tongue piece or catch f. which is secured by a set screw g.
and the parts are fixed in position. The rose may or may not be screwed to the
door and in no way assists to retain the parts but is merely for ornamentation, the
rose being the mount and whilst the rim or collar h. closely fits around the neck it
allows the knob to freely turn therein, or as in the door knobs I may dispense with
the rose and substitute a metallic cup or cap i. Figs. 22 and 23 which cap is formed
without the tubular piece and with a square aperture for the spindle end to pass
through which is extended somewhat in length so that it may be leaded into the
knob or otherwise secured.
By either arrangement the knob will appear as if fully mounted.
In the above described improvements it will be readily understood that the object
of my invention is to entirely do away with the ordinary method of mounting the
knobs or the spindles and at the same time to produce effective means as a substitute.
therefor, thus considerably cheapening the cost of production and producing a
better and securer method of attachment for the purpose, moreover an important
feature is, that breakage is prevented or minimized which is very liable to occur
when mounting china, glass, or such like knobs as hitherto adopted.
I do not limit myself to the exact details of the formation and construction of
my improvements as I may sometimes deem it expedient to vary the same as
occasion may require.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare what I.
claim is.

method of attaching the same the formation and arrangements set forth, described
