Improvements in Means for Attaching Door Knobs, Cupboard Turns
and the like to Spindles.
1, EDWARD VERNON BAILEY, of the Firm of Bailey and Mackey, Great Hampton
Row, in the City of Birmingham, Manufacturer, do hereby declare the nature
of this invention to be as follows:-
This invention has relation to means for affixing door knobs to cupboards turns
and the like to their spindles and has reference principally to such furniture in
which drilled-through spindles are employed and a small keep screw is made to
pass through the neck of the knob and engage the spindle.
In one form of my invention as applied to door knobs, a series of transverse
thoroughfare holes are drilled in a line along the spindle from the one end, or
from both ends, and the spindle is also split or divided longitudinally up its
middle, with the split intersecting the holes and running to a distance equal to
the range of the series of holes, which are of a less bore or diameter than of the
body of the pin passing through the neck of the knob.
This pin consists of a screwed upper end having a coned body and with the
tip or inner end being of a diameter a little greater than the bore of the holes.
The hole in the neck is screwed, so that by driving home the screw, its wormed
part engages the screwed hole in the neck whilst the coned body passes into one
of the holes in the knob and thereby opens out the split in the spindle, which is
expanded into the square unscrewed hole in the neck of the knob. The tip of
the locking pin may pass into a small hole formed for its reception on the
opposite side of the said hole in the neck.
As a further form, instead of the spindle being completely split, it may be
channelled for a distance inwards from the end, with the small holes to receive
the locking pin being continued through the bottom of the channel, which said
holes are of such a size as to admit of the tip of the locking pin passing there-
through to engage with the sinking on the opposite side of the neck to that
through which the said pin enters.
When the conical body of the screw is forced home, then the sides of the slot,
channel or groove open out laterally and the sides of the spindle thus expanded
exert a locking friction against the inside of the neck of the knob.
The application of my invention to cupboard turns and the like differs in no
essential respect from its application to door knobs or door furniture as herein
described.
Dated this 5th day of October 1899.

I, EDWARD VERNON BAILEY, of the Firm of Bailey and Mackey, Great Hampton
Row, in the City of Birmingham, Manufacturer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
This invention has relation to means for affixing door knobs, cupboard turns, and
the like to their spindles and has reference principally to such furniture in which
drilled-through spindles are employed and a small keep screw is made to pass
through the neck of the knob and engage the spindle.
Figure 1 of the accompanying drawings represents a knob and spindle con-
structed, or provided with means for connecting them to one another in a simple
and efficient manner in accordance with one form of my invention. In this view,
the spindle and the neck of the knob are represented in longitudinal section,
whilst the keep-screw or combined keep-screw and peg is shown in elevation.
Figure 2 is another view of the said knob and spindle, showing the latter in
plan, whilst the neck of the knob is represented in section upon the dotted line a,
Figure 1.
1. Figure 3 represents a cross section of Figure 1 upon the dotted line a¹.
Figure 4 shows a plan of the spindle and an elevation of the keep screw or
affixing pin separately.
The same letters of reference indicate corresponding parts in the said Figures 1
to 4 of the drawings.
According to this form of my invention, a series of transverse thorough-fare-
holes a, are drilled in a line along the spindle b, from the one end b¹, (or from
both ends) and the spindle is also split or divided longitudinally up its middle
at c, with the said split e, intersecting the holes a, and extending for a distance
equal to the range of the series of holes (or further as may be desired) which are
of a less width than the body of the pin d, passing through the neck e¹, of the
knob e.
The
This pin is represented separately in Figure 4, and consists of a screwed
upper end d, and a coned body d², with the shank or inner end d³, being of a
diameter a little greater than the bore or cross breadth of the holes a.
hole in the neck e', which is inward-tapered, is screwed, so that by driving home
the screw, its wormed part engages the screwed hole in the neck whilst the coned
body or peg passes into one of the series of holes or hole seatings in the spindle
and thereby opens out the split in the said spindle, which is expanded laterally
within the plain and slightly-back tapered hole et, in the neck of the knob.
Figure 5 represents, partly in elevation, and partly in longitudinal vertical
section, a modified form of knob and spindle connection in accordance with the
modified form of my invention.
Figure 6 represents a cross section thereof upon the dotted line ³.
In this arrangement, the spindle b is likewise provided with a series of holes a,
intersected by a longitudinal slit c, and is expanded by a conical-bodied pin d,
as before but with the head d³, of the pin made plain and lying within a plain
hole on one side of the neck e¹ of the knob e, which is slightly larger inwardly
than at the mouth but to this I do not limit myself as the sides may be parallel,
whilst the tip d, of the pin, which, when forced home, extends beyond the off
side of the spindle, is wormed and engages with a corresponding screw hole et in
the opposite side of the said neck.
Or the head of the locking pin may be screwed and engage with a wormed

page_text: hole in the neck of the knob as described and represented in Figures 1 to 4, but
the plain tip end d' may, as represented in Figure 7, extend beyond the off-side
of the spindle and engages with a plain hole et, formed for its reception within
the neck of the knob, opposite to the wormed hole aforesaid.
Instead of the body or peg part of the keep screw being tapered, it may be
plain, in which case the split, or the hole seatings intersected by the split would
be provided with a taper lead or mouth.
The application of my invention to cupboard turns and the like differs in no
essential respect from its application to door knobs or door furniture as herein
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 what
I claim is:―
First: In door and like furniture, the employment of a spindle having a
series of transverse thorough-fare holes formed in a line along one end, or along
each end, and intersected by a longitudinal split or division, in combination with
a keep screw having a peg end or body adapted to pass into the hole seatings in
the spindle and laterally expand the same within the neck of the knob, substan-
tially as herein described and also as set forth in the accompanying drawings.
Secondly-In door and like furniture, the employment of a spindle having a
series of transverse thorough-fare holes formed in a line along one end or along
both end and intersected by a longitudinal split or division, in combination with
a keep screw having a peg or body part adapted to pass into the hole seatings in
the spindle for the purpose of laterally expanding the same within the neck of
the knob, and with the lower end or tip of the same extending beyond the spindle
and engaging with a corresponding hole in the said neck of the knob, substan-
tially as herein described and also as set forth in Figures 5, 6 and 7 of the accom-
panying drawings.
