PROVISIONAL SPECIFICATION.
Improved Means for Attaching Door Knobs to Spindles.
I WILLIAM KNEEN of 149ª Aldersgate Street in the City of London Manufacturer
do hereby declare the nature of this Invention to be as follows:-
The object of my Invention is to provide means whereby the screw or analogous
device used for securing knobs to their spindles is prevented from accidentally
becoming loosened. For this purpose I make the screw pin or the like split or
divided at its point end and when it is passed through the neck of the knob and
spindle the said split point end is turned outwards so that it becomes practically
enlarged and will not be liable to become loosened and leave its place whilst by forcing
the split parts together the screw pin or the like can be readily removed when desired.
I prefer to provide the neck of the knob with a countersink or recessed part to receive
the turned out parts of the screw pin or the like.

COMPLETE SPECIFICATION.
Improved Means for Attaching Door Knobs to Spindles.
I WILLIAM KNEEN of 149ª Aldersgate Street in the City of London Manufacturer
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:-
The object of my Invention is to provide means whereby the screw or analogous
device used for securing knobs to their spindles is prevented from accidentally
becoming loosened. For this purpose I make the screw pin or the like split or
divided at its point end and when it is passed through the neck of the knob and
spindle the said split point end is turned outwards so that it becomes practically
enlarged and will not be liable to become loosened and leave its place whilst by forcing
the split parts together the screw pin or the like can be readily removed when desired.
I prefer to provide the neck of the knob with a counter sink or recessed part to receive
the turned out parts of the screw pin or the like.
The accompanying drawing shews a knob A and spindle B attached by means of a
screw C split according to my Invention. Figure 1 shews the screw separately
Figure 2 shows the knob and spindle with the screw before the split end is splayed
out and Figure 3 shews the same with the split end of the screw splayed out. The
end of the screw pin C is split at c³ and after it is screwed into place as shewn in
Figure 2 the split part is by means of any convenient tool splayed out as shown in
Figure 3. I preferably provide a countersunk part as at a³ in the neck of the knob
to receive the splayed out parts but I may if desired dispense with this and make the
screw long enough for the split end to protrude beyond the surface of the neck of the
knob and splay out the part so protruding. I prefer to screw the pin as shewn but if
desired it may be plain and be secured simply by the splaying out of the ends.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is
First-In, or for, attaching door knobs to spindles a screw or pin with a split end
which split end is splayed out to secure the screw or pin in place.

page_text: Second-The means for attaching door knobs to spindles consisting of a screw or
pin split at the end opposite the head end and a countersunk hole in the neck of the
knob for receiving the split part when splayed out as hereinbefore described and
shewn.
