County of Warwick, Manufacturer, do hereby declare the nature of said invention
for "IMPROVEMENTS IN ATTACHING KNOBS TO THE SPINDLES OF LOCKS AND
LATCHES to be as follows:-
"
In the ordinary method of connecting knobs to their spindles, the square spindle
is made in one piece, and fits into a corresponding hole in the neck of the knob or
bandle and there secured by passing a screw pin through the neck of the knob,
which takes into one or other of a series of countersunk holes on either side the
sprindle. This method of connecting always proves uncertain from the vibration
and jar of the door, to which it is connected, causes the screw pin to become loose,
and further, there is considerable difficulty in giving a nice adjustment to the knob
on the spindle to suit the varying thickness of doors to which they are or may be
applied. By my invention the difficulties before described are entirely over come,
the knob is capable of being adjusted with the greatest possible nicety upon the
spindle so as to suit any thickness of door; and when once adjusted and fixed,
there is no liability of either becoming loose, or detached.
My said invention consists in forming or making the spindle of the knob in
halves longitudinally, and when placed together they preserve the square form.

spindle for fitting into the corresponding hole in the neck of the knob; the said
divided spindle is affixed within the neck of the knob which is made preferably to
taper slightly inwards, by a screw pin with a pointed end, which passes through
the neck of the knob in the ordinary way, and takes between the half spindles,

divided spindle into the body or neck of the knob, thereby firmly securing the
said knob to its spindle.
In carrying out my invention, I make the halves of the divided spindle from
half round rods of metals, preferably rolled to that section; that is, the rods are
flat upon one side, and convex upon the other, of the thickness of a half spindle;

Instead of making the halves of the spindle to the section described, they may

into and passes right across the neck of the knob, dividing the half spindles to the
extent of the thickness of the pin. Where a pin of this form is used, the half
spindles will be required to be made slightly thinner, for the purpose as described.
The end of the tapered pin may either screw into the neck of the knob or be
affixed by a small nut or screw washer.

and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
In the ordinary method of connecting knobs to their spindles, the square spindle
is made in one piece, and fits into a corresponding hole in the neck of the knob or
handle, and there secured by passing a screw pin through the neck of the knob,
which takes into one or other of a series of countersunk holes on either side the
spindle. This method of connecting always proves uncertain from the vibration'
and jar of the door, to which it is connected; causes the screw pin to become loose,
and further, there is considerable difficulty in giving a nice adjustment to the knob
on the spindle to suit the varying thickness of doors to which they are or may be
applied By my invention the difficulties before described are entirely overcome,
the knob is capable of being adjusted with the greatest possible nicety upon the
spindle so as to suit any thickness of door; and when once adjusted and fixed, there
is no liability of either becoming loose or detached.

page_text: My said invention consists in forming or making the spindle of the knob in
halves longitudinally, and when placed together they preserve the square form
in section of an ordinary spindle, or rather preserve the four angles of a square
spindle for fitting into the corresponding hole in the neck of the knob; the said
divided spindle is affixed within the neck of the knob which is made preferably to
taper slightly inwards, by a screw pin with a pointed end, which passes through
the neck of the knob in the ordinary way, and takes between the half spindles,
which when driven home, forces outwards or expands the terminal ends of the
divided spindle into the body or neck of the knob; thereby firmly securing the said
knob to its spindle.
In carrying out my invention, I make the halves of the divided spindle from
half round rods of metal, preferably rolled to that section; that is, the rods are flat
upon one side, and convex upon the other, of the thickness of a half spindle; and
when the curved sides of two suitable lengths are presented to each other, a spindle
with square handles is thus forined, with grooves or channels running on either
side thereof The knob is placed and adjusted upon the divided spindle with the
screw. hole in its neck, coming opposite the division, when by driving home the
screw pin, its taper end wedges between the halves of the spindle and thereby.
expands, wedges and slightly forces open the terminal ends of the said spindle into
the neck and body of the knob; thereby firmly and effectually securing the knob
to its spindle..
:
Instead of making the halves of the spindle to the section described, they may be
made triangular; so that the > sides are presented to each other when placed
within the neck of the knob-Instead of employing a short screw as described, the
said screw may be made in the form of a tapered pin with a screwed end, which
screws enter into and passes right across the neck of the knob, dividing the half
spindles to the extent of the thickness of the pin-Where a pin of this form is used,
the half spindles will be required to be made slightly thinner, for the purpose as
described The end of the tapered pin may either screw into the neck of the knob
or be affixed by a small nut or screw washer.
I will now proceed to describe with reference to the accompanying Drawing, tho
manner in which the same is to be performed.
Figure 1 is a plan, and figure 2 is a longitudinal vertical section of a knob and
spindle constructed and connected together according to my invention-Figure 3 is
a longitudinal section upon the line A B with one of the knobs removed-Figure 4
is a transverse vertical section on the dotted lines C D-Figure 5 is the same
section as figure 4 but with the affixing screw removed-Figure 6 is a separate
view of the affixing screw-Figure 7 are the segments or spindle halves in plan-
Figure 8 is an end view of the said half spindle halves figure 7-Figure 9 is an
end view of the neck of the knob showing the shape of the hole through which
the halves of the segmental spindle pass and wherein they lie and are affixed-
Figure 10 is a modification, where the halves of the divided spindle ar forced
asunder and bound firmly within the hole in the neck of the knob by a taper
ended screwed pin-The hole in the neck of the neck of the knob may be square
or of any other figure in cross section to follow the cross section of the spindle or
parts composing the spindle.
The same letters of reference indicate corresponding parts in the several figures
of the Drawing.
a is the knob, and b b are the halves of the segmental spindle preferably formed
from half round or nearly half round rods of metal, rolled to that section; that is;
the rods bb figure 7 are flat upon the sides b 6, and convex or angular upon the
sides 6363, and when placed together as in figures 1 and 2, a square spindle is thus
formed, with grooves or channels running on the top and bottom sides thereof, or
upon two opposite sides-The knob a is placed and adjusted upon the divided
spindle with the screw hole a² in its neck a³ coming opposite the division of the
halves of the spindle-a is the hole in the neck of the knob of somewhat the
figure of the cross section of the combined halves of the spindle, the said hole is

page_text: slightly tapered inwards so as to allow the ends of the spindle to slightly open out
or expand on the taper ended screw pin o being driven home.
To connect a knob to its spindle, it is only necessary to place the knob upon the
said spindle in the desired position to which it is to be affixed, with one of the
troughed or channelled sides coming opposite the screw hole in the neck of the
knob, when by screwing home the screw pin c with its tapered or pointed end c³,
the knob is firmly and securely affixed in its adjusted position upon its spindle, by
the taper or pointed end c³, of the screw pin c, wedging between and forcing
outwards or asunder the balves of the spindle, or rather the terminal ends of the
divided spindle both into the neck, and into the body of the knob as best seen in
figures 1, 2 and 4.
In figure 10 the opening or the jambing of the half spindles in the hole in the
neck of the knob, is effected by a tapered screw pin, which passes right across the
neck of the knob-d is the screw pin, b are the half spindles, and a³ is a square
hole in the neck of the said knob-In this case, the inside edges of the spindle are
inclined instead of curved-So that by the forcing of the tapered screwed pin
between the inside angular faces of the halves of the spindle, the knob is firmly and
securely attached thereto.
I wish it to be observed that the knobs can be adjusted upon their spindles with
the greatest possible nicety, as there is no determinate positions where the affixing
is to be effected as is common with knobs and spindles of the ordinary kind.
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
I claim is
First Affixing or attaching knobs to lock or latch spindles, by expanding or
forcing asunder the segmental halves of a split or divided spindle, into the hole in
the neck, or into the body of the knob, or into both, by the driving home of the
pointed or taper end of a small screw, screw-pin or plain pin which screws into or
passes through the neck of the said knob, as described and illustrated.
Secondly A knob spindle, split or divided longitudinally, preferably made up
from half round or triangular (in cross section) rods or lengths of rolled metal, which
when placed together, with the curved or angular sides in juxta position they
constitute or form a segmental spindle, with grooves or channels running on two
opposite sides, wherein the point or the taper end of the screw or pin wedges itself
for the opening out of the said halves of the spindle into the neck and body of the
knob as described and illustrated-Also the formation of the eye or hole in the
neck of the knob for the purpose as set forth.
