Improvements in the Method of Securing Knobs and Handles to the
Spindles of Door Locks, Latches, and the like.
I CHARLES HENRY SIDEBOTHAM of 3 Macdonalds' Lane, Corporation Street,
Manchester, in the County of Lancaster, Agent for Building Specialities, do hereby
declare the nature of this invention to be as follows:-
My said invention relates to improvements in the mode of securing knobs and
handles to the spindles of door locks, latches and the like and has for its object to
prevent such knobs and handles from working loose or coming off as happens so
frequently under the present method of securing such knobs and handles.
According to my invention the end of the spindle is screwed and I screw the
knob or handle thereon.
The spindle has one or more slots or gutters cut longitudinally in the screwed
portion. In the collar of the knob or handle I cut a slot and I bore a hole through
the collar at the slotted part and screw it to receive a threaded pin which is screwed
through the collar so that the point enters the gutter in the spindle, the head of

screwed upon the spindle up to the proper point and then I screw the pin into the
slotted portion of the collar and so as to project into the gutter in the spindle, the
knob and the spindle being thus securely fastened together. To keep the screwed
locking pin in its position and prevent it from coming out I make a ring to slip

then placed over the collar imprisoning the stop block ring and keeping it in
position, the rose being fastened to the door by screws in the ordinary manner.
The handle or knob being screwed and locked on the spindle by the aforesaid
means, any pull exerted on the knob is imparted directly to the spindle and does
not fall upon the rose, which is therefore in no danger of being loosened or
pulled off.
A knob or handle attached according to my invention cannot possibly become
loose or turn on the spindle or be pulled off, while by removing the rose, slipping back
the stop block ring and unscrewing the pin the handle or knob can at any time be
removed.

I CHARLES HENRY SIDEBOTHAM of Macdonalds' Lane, Corporation Street,
Manchester, in the County of Lancaster, Agent for Building Specialities, 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 and accompanying drawings:
My said invention relates to improvements in the mode of securing knobs and
handles to the spindles of door locks, latches and the like and has for its object to
prevent such knobs and handles from working loose or coming off as happens so
frequently under the present method of securing such knobs and handles.
According to my invention the end of the spindle is screwed and I screw the
knob or handle thereon. The spindle has one or more slots or gutters cut
longitudinally in the screwed portion. In the collar of the knob or handle I cut a
slot and I bore a hole through the collar at the slotted part and screw it to receive
a threaded pin which is screwed through the collar so that the point enters the
gutter in the spindle, the head of the pin lying flush with the bottom of the slot
in the knob collar. The knob is screwed upon the spindle up to the proper point
and then I screw the pin into the slotted portion of the collar and so as to project
into the gutter in the spindle, the knob and the spindle being thus securely fastened
together.
'
To keep the screwed locking pin in its position and prevent it from coming out
I make a ring to slip over the collar the said ring carrying a stop block which
fills the slot made in the collar and covers over the pin, so that it cannot possibly
work out.
The rose is then placed over the collar imprisoning the stop block ring and
keeping it in position, the rose being fastened to the door by screws in the ordinary
manner. The handle or knob being screwed and locked on the spindle by the
aforesaid means, any pull exerted on the knob. is imparted directly to the spindle
and does not fall upon the rose, which is therefore in no danger of being loosened
or pulled off.
A knob or handle attached according to my invention cannot possibly become
loose or turn on the spindle or be pulled off, while by removing the rose, slipping
back the stop block ring and unscrewing the pin the handle or knob can at any
time be removed.
To render my invention fully understood I will now proceed to describe the same
more particularly reference being had to the annexed sheet of drawings.
Fig. 1 is an edge view of a door with handles applied in my improved manner.
Fig. 2 is a detached view showing the slotted knob collar with the stop ring
slipped clear of the screw.
Fig. 3 is a similar view with the stop ring slipped over the collar.

Fig. 4 is a section of the spindle showing the face of the knob collar and stop 4
ring.
Fig. 5 is a perspective view of the stop ring.
The handles or knobs are marked a and b. The knob a is screwed upon the
square spindle c, while the other end of the spindle may be rivetted into the
knob b.
The spindle c is screwed at one end to receive the knob a and is furnished on
two or more sides with gutters c¹ which are most clearly apparent in the sectional
view Fig. 4. The collar a' of the knob a has a slot a cut in it in the direction of
its axis.

page_text: The collar a' is also bored at this slotted part and screwed to receive a threaded
pin d which is screwed through the collar so that the point enters the gutter clin
the spindle, the head of the pin lying flush with the bottom of the slot a' in the
collar a². When applying the knob a to the spindle c I screw it on till the face of
the collar a rests against the side of the door e. Before thus applying the knob,
I slip over the collar the rosef and the locking or stop ring g. This locking ring
fits the collar a¹ and is formed with a tongue g which exactly fits the slot a' in the
collar. The knob a having been screwed upon the spindle to the proper point, I
screw the threaded pin d into the collar till the point projects into the gutter c¹ in
the spindle c, the knob and spindle being thus securely fastened together. I now
slip the locking ring g along the collar, say from the position in Fig. 2 to the
position in Fig. 3 thereby drawing the tongue gl into the slot a' which it fills up.
Thus the screwed locking pin d is covered and kept down and cannot come out or
work back. The ordinary rose f is then pushed over the collar and screwed to the
door by screws f¹ in the ordinary manner. The locking ring g is then imprisoned
between the rose f and the door so that it cannot get out of position. The handle
or knob a being screwed and locked on the spindle by the aforesaid means, any
pull exerted on the knob is imparted directly to the spindle and does not fall
upon either rose, so that these are in no danger of being loosened or pulled off.
By removing the rose, slipping back the locking ring 9 and screwing back the
pin d, the handle or knob a can at any time be unscrewed from the spindle and
removed.
The mere screwing of a knob or handle upon the end of the spindle and even
the securing of the same to the spindle by means of a set screw passing through
the collar of the knob and entering a gutter in the spindle, is not new, but the
locking ring with tongue for preventing the working loose of the said set screw is
novel and is the essential of my invention.
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.
1. As means for maintaining handles and knobs securely upon their spindles, the
locking ring g with tongue g¹ whereby the set screw for securing the knob to the
spindle is prevented from working back or becoming loose, substantially as herein-
before described and shown.
2. As means for maintaining handles and knobs securely upon their spindles, the
knob a having its collar a slotted as described, in combination with the locking
ring g and tongue 9 occupying the slot in the collar so as to confine and prevent
the working back of the set screw d, the said tongued locking ring being held in
position by the rose, all substantially as described and shown.
3. The general arrangement, construction and combination of improved means
for more effectually securing knobs and handles to the spindles of door locks,
latches and the like, substantially as hereinbefore described and shown.
