I ARTHUR MOORE of Thimble Mill Lane, Aston, in the county of Warwick Brass-
founder do hereby declare the nature of this invention to be as follows:-
This invention relates to the securing of knobs or handles upon their spindles, and
consists in the arrangement of a conical screw or pin, in combination with a divided
or slotted spindle.
This invention may be applied either to plain square spindles, square spindles
having screw threads upon their angles, or other sections of spindles. In describing
this my invention as applied to an ordinary door furniture, and plain spindle, I may
say; may apply it either to both ends of the spindle, or I may make the one end
secure by any method I please, and apply this my invention to the other end only.
Assuming the latter, I cut a slot up the middle of the spindle, rather farther along
than is required for the knob to slide up. The outer edges of this slot (near the flat
surface of the spindle) may or may not be bevilled or countersunk. I then form the
knob much in the same way as ordinarily, only, that I should make the "small
screw" hole to pass through both sides of the neck, and tap or screw the off side, the
front hole being somewhat larger.
When the slotted spindle passed into the neck of the knob, I insert through the
hole in the one side of the knob, and also through the slot in the spindle into the
screwed hole upon the opposite side of the neck of the knob, a screw pin, having an
enlarged conical part, which when being screwed up in its place impinges upon the
two sides of the slot in the spindle, and springs them open, which not only jams them
tightly against the sides of the hole in the neck of the knob, but also forces thein to
assume upon their exterior a taper form, enlarging as it approaches the end of such
spindle, thus effectually preventing the removal of the knob. I may in some instances

page_text: only provide the screw to pass through the one side of the neck, but still to act upon
and open the two sides of the spindle in a similar manner. The slotted form of the
spindle may be either upon the flat, or it may be across the angles of such spindles.
Further, the slot may in some instances be formed, leaving a portion of the end of the
spindle untouched, except just cutting it through, for the sake of parting the two
sides, or the slot may be formed parallel right through to the end of the spindle, and
then the ends turned inwards, so that in each case the knob could not be removed
from the spindle, unless the screw pin was not only slackened, but removed. Another
important feature in this my invention is, that in most cases after having passed the
pin into its place, I should rivet over the end of the said pin, or otherwise prevent its
removal.
This my invention would be applicable to all kinds of knobs or handles, where the
knobs are secured to a spindle or its equivalent, such as door knobs, cupboard door
knobs, drawer knobs, cupboard turns &c. &c.

1 ARTHUR MOORE of Thimble Mill Lane Aston, in the county of Warwick Brass-
founder 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 :-
:-
This invention relates to the securing of knobs or handles upon their spindles and 2
consists in the arrangement of a conical screw or pin in combination with a divided
or slotted spindle.
This invention may be applied to either plain square spindles, square spindles
having screw threads upon their angles, or other sections of spindles. In describing

page_text: this my invention as applied to an ordinary door furniture and plain spindle I may
say, I may apply it either to both ends of the spindle, or, I may make the one end
secure by any method I please, and apply this my invention to the other end only.
Assuming the latter, I cut a slot up the middle of the spindle, rather farther along
than is required for the knob to slide up. The sides of this slot may be bevilled or
tapered to suit the taper part of the screw pin if desired.
I then form the knob much in the same way as ordinarily, only that I should
make the "small screw" hole to pass through both sides of the neck, and tap or screw
the off side, the front hole being somewhat larger.
When the slotted spindle is passed into the neck of the knob I insert through the
hole, in the one side of the neck of the knob, and also through the slot in the spindle
into the screwed hole upon the opposite side of the neck of the knob, a screw pin,
having an enlarged conical part, which when being screwed up in its place, impinges
upon the two sides of the slot in the spindle, and springs them open, which not only
jams them tightly against the sides of the hole in the neck of the knob, but also
forces them to assume upon their exterior a taper form, widening as it approaches the
end of such spindle, thus effectually preventing the removal of the knob. I may in
some instances only provide the screw to pass through the one side of the neck, but
still to act upon and open the two sides of the spindle, in a similar manner.
The slotted form of the spindle may be either upon the flat, or it may be across the
angles of such spindles.
Further, the slot may in some instances be formed leaving a portion of the end of
the spindle untouched, except just cutting it-through for the sake of parting the two
sides, or, the slot may be formed parallel right through to the end of the spindle, and
then the ends turned inwards, so that in each case the knob could not be removed
from the spindle, unless the screw pin was not only slackened, but removed.
Another important feature in this my invention, is, that in most cases after having
passed the pin into its place, I should rivet over the end of the said pin, to prevent its
removal.
Having now described the nature of this my said invention I will now more clearly
explain how it is to be performed, with the aid of the accompanying illustrative sheet
of drawings, upon which are figures and letters of reference, like letters referring
throughout the several views, to the same thing or part.
Fig. 1, is a view shewing this my invention as applied to an ordinary door
furniture.
Figs. 2 & 4 shew enlarged details of Fig. 1.
a, is the knob, to be secured to the spindle b; c, is the slot cut in the spindle, and
which in Fig. 2 is shewn widened out a little at the front end, so that upon being
compressed or closed together again in order to admit of its being passed into the
neck of the knob, it would again spring open, preventing the too ready removal of
the knob therefrom, when the screw pin may not be tightened up; d, is the taper
screw pin. It will be readily seen that upon passing the spindle into the knob a,
then inserting the screw pin, and screwing it (the pin) home, the two sides of the
slotted spindle are forced outwards in a taper form, somewhat similar as shewn in
Fig. 1, thus preventing the removal of the knob from the spindle.
Fig. 3 shews this my invention applied to a modified form of spindle, and hole in
the neck of the knob, the former having a screw thread formed upon its angles, and
the latter, tapped to suit. In adjusting the knob a, into its position, in this case, the
said knob a, would be screwed along the spindle into position, and afterwards the pin
inserted when in order to draw or slide the knob back the pin would first be
removed; the adjustment of the position of the knob in this case being limited to at
least one half revolution.
Figs. 5 & 6 show how in some instances I may make the slot in the spindle b, of a
taper or bevilled form, in order to fit the taper of the screw pin d.
Fig. 6 further shews a modification in form of the screw pin d, where the said
screw pin only passes through the one side of the neck of the knob, the screw part of
the pin being upon the rear side of the cone.

page_text: Instead of cutting the slot c in the spindle right through to the end of the spindle
as in Fig. 1, I may if desired, leave an end thereto, as at e Fig. 7, cutting simply a
slot through such end to enable the two parts to be sprung open. Or, again, I may
cut the slot right through as in Fig. 1, and then bend over the ends as in Fig. 8; in
both these two last cases (Figs. 7 & 8) the object being to prevent the withdrawal of
the Knob from the spindle unless the pin d is entirely removed.
Again, in order to prevent the possibility of losing the pin d, Figs. 1, 4 & 5 I may
in the case of open ended slotted spindles, rivet over, the end of the said pin d, as
shewn at g Fig. 4, before passed on to the spindle, and in the case of closed spindles
Figs. 7 & 8, rivet it over after the knob is passed upon the spindle and the pin
inserted; when it would only be necessary to slacken the pin d in order to adjust the
knob into position.
This my invention would be applicable to all kinds of knobs or handles, where the
knobs are secured to a spindle, or its equivalent, such as door knobs, cupboard
knobs, drawer knobs, cupboard turns &c. &c.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1st. The improvements in the attaching of knobs or handles to their spindles, as
hereindescribed and illustrated in Figs. 1, 2, 4, 7 & 8, that is to say; the combination
of a conical screw with a slotted plain spindle, as, and for the purposes specified.
2nd. The combination of a conical screw with a slotted spindle screwed upon its
angles, or exterior surface, and working in a tapped or screwed hole in the neck of
the knob, similarly as illustrated in Fig. 3.
3rd. The combination of a conical pointed screw, with a slotted spindle, similarly as
hereindescribed and illustrated in Figs. 6, 2, 7 & 8.
4th. The rivetting over of the screw pin which passes through both sides of the
neck of the knob, to prevent its removal or loss from the said knob, as herein-
described and illustrated in Fig. 4.
Dated this 20th day of April 1887.
