I ENOCH SUMMERFIELD of No 40 New Street Aston near Birmingham in the
County of Warwick Locksmith do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN ADJUSTING AND FIXING DOOR KNOBS TO THEIR SPINDLES "
to be as follows:-
I make the spindle square in cross section and I form a screw thread on the
angles of that end on which the adjustable knob is to be fitted as usual. I also
make the hole in the neck of the adjustable knob into which hole the spindle takes
square in cross section so that the knob can slide but cannot rotate on the spindle.
Upon the screwed angles of the spindle I fit a screw nut which by rotation can be
adjusted to any required position on the screwed end of the spindle. The said
screw nut has a groove at its middle and when the adjustable knob is put in its
place on the spindle the open end of its neck fits upon and covers the said screw
nut. The end of the neck has a screwed hole into which a screw pin may be
screwed the end of the said screw pin engaging in the groove in the screw nut.
The action of the parts is as follows-The spindle to the unscrewed end of
which the fixed knob is attached is passed through the door and lock or latch and
the screw nut is screwed onto the screwed end of the spindle until it abuts against
the door. The adjustable knob is then passed onto the spindle and a screw pin
screwed into the hole in its neck. The end of the said screw pin enters the groove
in the screw nut and the knob is thereby fixed in its place.
I prefer to use with the arrangement described a rose having a collar or neck
engaging with the neck of the knob. Great steadiness is given to the knob by the
use of a rose of the kind described.
Instead of making the groove in the screw nut circular it may be made square
or of other angular figure.

I ENOCH SUMMERFIELD of N° 40 New Street, Aston, near Birmingham in the
County of Warwick, Locksmith do hereby declare the nature of my Invention
for "IMPROVEMENTS IN ADJUSTING AND FIXING DOOR KNOBS TO THEIR SPINDLES
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
•
My invention consists of the arrangement or combination of parts hereinafter
described for adjusting and fixing door knobs to their spindles.
I make the spindle square in cross section and I form a screw thread on the
angles of that end on which the adjustable knob is to be fitted as usual. I also
make the hole in the neck of the adjustable knob into which hole the spindle takes
square in cross section so that the knob can slide but cannot rotate on the spindle.
Upon the screwed angles of the spindle I fit a screw nut which by rotation can be
adjusted to any required position on the screwer end of the spindle: The said
screw nut has a groove at its middle and when the adjustable knob is put in its
place on the spindle the open end of its neck fits upon and covers the said screw
nut. The end of the neck has a screwed hole into which a screw pin may be
screwed, the end of the said screw pin engaging in the groove in the screw nut.
The action of the parts is as follows; The spindle to the unscrewed end of which
the fixed knob is attached is passed through the door and lock or latch and tho
screw nut is screwed onto the screwed end of the spindle until it abuts against
the inside of the rose. The adjustable knob is then passed onto the spindle and a
screw pin screwed into the hole in its neck. The end of the said screw pin enters
the groove in the screw nut and the knob is thereby fixed in its place.
I prefer to use with the arrangement described a rose having a collar or neck
engaging with the neck of the knob. Great steadiness is given to the knob by the
use of a rose of the kind described.
Figure 1 of the accompanying Drawings represents partly in side elevation and
partly in longitudinal section a pair of door knobs, the moveable or adjustable knob
of which is adjusted on and fixed to its spindle by the arrangement or combination
of parts constituting my invention; Figure 2 represents a cross section of the same
taken on the line a, a Figure 1; Figure 3 represents the fixed knob and its spindle
the said spindle being passed through the door ready to receive the rose, the
adjusting screw nut and the moveable or adjustable knob; Figure 4 represents
the same after the rose and screw nut have been passed onto the spindle; Figure 5
represents in front elevation the rose and screw nut and Figure 6 represents the
rose in side elevation; Figure 7 represents the moveable knob partly in elevation
and partly in longitudinal section and in front elevation; Figure 8 represents in
side elevation, Figure 9 dn section and Figure 10 in front elevation the screw nut
detached.
The same letters of reference indicate the same parts in the several Figures of
the drawings

.b is the fixed knob and c the moveable or adjustable knob; d is the spindle
square in cross section and screwed on the angles of that end on which the
adjustable knob c is to be affixed. The hole o' in the said knob c for taking upon.
the spindle is square in cross section so that the knob can slide upon the spindle
but cannot rotate upon it. In the front of the knob c ia a cylindrical recess c³ and
in the neck of the said knob c is a screwed hole for the neck screw pin o³ to
engage with; e is the adjustable screw nut for screwing upon the screwed angles
of the spindle &; e is the groove in the middle of the screw nut e for receiving
the end of the neck screw pin c, the said groove e² when the moveable knob o is
adjusted on the spindle coinciding with the screwed hole c in the neck of the said
knob; fis the rose used with the moveable knob the said rose having a collar f* for
fitting over the neck of the knob and preventing the neck screw pin from rising
out of its screwed hole.
The adjusting and fixing of the moveable knob on its spindle is effected in the
following manner.
The spindle & carrying the fixed knob b is passed through the door and lock or
latch, the screwed end of the spindle being made to protrude from the door in the
manner represented in Figure 3. The rose f, f' is next placed on the spindle and
made to bear against the door and the externally grooved screw nut e, e³ is screwed.
upon the spindle until it abuts against the rose f as represented in Figure 4. The
moveable or adjustable knob c is then passed onto the spindle, the plain cylindrical
recess at c³ in the front of the neck of the knob fitting upon and covering the said
screw nut e, e² and also fitting within the collar f* of the rose as illustrated in
Figure 1. When in this position the screwed hole c in the neck of the knob c is
Bituated opposite the groove e³ in the screw nut e. The hole fs in the collar f2 of
the rose f being made to coincide with the screwed hole c' in the neck of the knob,
a screw pin c is screwed into the said neck hole c¹ the end of the screw pin
entering the groove e² in the screw nut e and its flat bottom bearing against the
bottom of the said groove as represented in Figure 1. The knob c is thereby fixed
to the spindle through the screw nut e, e³ the latter being incapable of rotating on
the said spindle. The collar of the rose is next turned so as to bring an
unperforated part of the said collar over the screw pin c as represented in Figures
1 and 2 and the rose is finally fixed to the door in the usual way.
Although I prefer to use with the arrangement described a rose having a collar
or neck engaging with the neck of the moveable knob as described and illustrated
whereby great steadiness is given to the knob yet a rose without a collar fƒ³ may
be used with my improvements.
Instead of making the bottom of the groove in the screw nut circular as
described and illustrated it may be made square or of other angular figure that is
the bottom of the neck screw pin may take a bearing upon a flat surface instead of
upon a curved surface.
The groove into which the screw pin takes may be made in the neck of the
moveable knob instead of in the adjusting screw nut and the hole for the screw pin
may be made in the adjusting screw nut instead of in the neck of the moveable
knob.
This modification of my invention is represented partly in side elevation and
partly in section in Figure 11, the moveable knob .separately in side elevation in
Figure 12 and end elevation in Figure 13 and the adjustable screw nut in side
elevation in Figure 14, section in Figure 15 and front elevation in Figure 16.
In this modification the groove in the neck of the moveable knob c is marked co
and the screwed hole in the adjusting screw nut e for the screw pin c to take into,
is marked e. The screw nut e having been adjusted on the screwed projecting
end of the spindle d as before described, the moveable knob c is pushed onto the
said spindle until its neck passes into the recess e in the screw nut e and the
collar cabuts against the face of the screw nut e. The groove c³ in the neck of
the moveable knob c is thereby brought opposite the screwed hole e³ in the screw
nute and the screw pin c is passed into the said hole 6 and into the groove c³ for

page_text: fixing the position of the moveable knob and the screw nut as illustrated in
Figure 11. The rose ƒ is then turned into the proper position and fixed as herein
before described.
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 I claim
as my invention of "Improvements in adjusting and fixing door knobs to their
spindles "
The combination of the externally grooved adjusting screw nut e, eª and plain
recess c³ at the front end of the sliding adjustable knob for fitting over the said
screw nut e, e², with the neck screw pin o for taking into the groove of the said
screw nut and preventing its rotation substantially as hereinbefore described and
illustrated in Figures 1 to 10 both inclusive of the accompanying Drawings the
said combination of parts being used preferably with a necked or collared rose;
also the modification of the fixing parts hereinbefore described and illustrated in
Figures 11 to 16 both inclusive of the accompanying Drawings.
