I, ALBERT HOGG of Queens Road, Aston in the county of Warwick, Machinist
do hereby declare the nature of my invention for IMPROVEMENTS IN THE ADJUSTING
AND ATTACHMENT OF DOOR KNOBS OR HANDLES TO THEIR SPINDLES, to be as
follows:-
This invention relates to the construction and arrangement of parts in connection
with the handle or knob and its spindle whereby a perfectly secure attachment is
effected independent of the door itself, and may be so made, as that it is imposible
for any of its parts to get lost even when the knob and its spindle are separated.
At one end of the spindle the knob may be fixed, or, at both ends my improved
attachment may be used, but assuming that the knob at one end is fixed the spindle
at the other end may in cases where there is not a very great strain upon the knob,
be left quite plain. I insert the free end of the spindle through the lock and door,
ready to receive the loose knob. This loose knob is provided with an internal
square or other shaped hole to suit the section of the spindle. Upon the outer
surface of the neck of the knob is provided a screw thread for the purpose of
receiving a screwed collar hereinafter mentioned. At a convenient part along the
neck of the knob a groove is also provided. I also provide a collar having a hole
corresponding to the section of the spindle, and with a cone at one or both ends,
upon its exterior diameter. This conical collar may be in one piece, and having a
slit cut through one of its sides, or, it may be in two pieces.
Also I provide a screwed collar or cap, having in its internal diameter a screw
thread corresponding to the exterior screwed thread upon the neck of the knob,
and also having a conical part, corresponding to the conical collar before mentioned,
and at a point corresponding (when in position) to the groove mentioned in the
neck of the knob, a hole is made to receive a pin or stud.
If the conical collar is coned at both ends, the front internal part of the neck of
the knob is also coned to suit.

page_text: When the conical collar is placed within the screwed collar, which in its turn is
screwed on to the neck of the knob, until the pin or stud hole in its diameter comes
over the groove in the neck, this stud or pin is then inserted into and projects
beyond the hole into the said groove, which prevents the screwed collar being
removed from the neck of the knob, the said groove being wider than the diameter 5
of the pin or stud so as to allow of a certain amount of lateral motion.
Thus when passed on to the spindle and the screwed collar rotated, the conical
collar is closed tightly upon the spindle, and thus in a simple manner securing
itself thereto.
In some cases where there is more severe strain the spindle is notched or serrated I
so as the grip may be increased.

I, ALBERT HOGG of Queens Road, Aston, in the county of Warwick Machinist.
do hereby declare the nature of my invention for IMPROVEMENTS IN THE ADJUSTING
AND ATTACHMENT OF DOOR KNOBS OB HANDLES TO THEIR SPINDLES, 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 construction and arrangement of parts in con-
nection with door handles or knobs, and their spindles, whereby a firm and secure
attachment is effected independent of the door itself, and may be so made, as that
it is impossible for any of the parts to become easily detached and lost, even when
the knob and spindle are separated from each other.
In order to describe this my invention more minutely I have appended hereunto
a sheet of drawings, upon which are figures and letters of reference, and upon which
like letters throughout refer to the same thing.
At one end of the spindle the knob a, may be fixed, that is, permanently
attached, or, if desired this my improved method of attachment may be adopted at
each end, but for the present description, assuming that the one end is fixed, the
spindle at the other end where the improved method of attachment takes place,
may, (where there is not much strain when in use) be left quite plain, or in other
cases where there is heavy wear or severe strain I may notch or serrate the spindle
similarly as shewn at b, Figs. 1 & 2, so that the gripping power may be increased.
The free end of the spindle c, is inserted through the door and lock, or latch,
ready to receive the loose knob d, Figs. 1. & 2. This loose knob d is provided at e,
with an internal square or other shaped hole to suit the section of the spindle.
Upon the outer surface of the neck of the knob at f, Figs. 1 & 2 is provided a
screw thread for the purpose of receiving the screwed collar or cap g, Figs. 1 & 5.
This screwed part at f, may be in some cases left unbroken, or in other cases
I may remove part of the thread by forming a groove at h, Figa 1 & 2.
I further provide a conical collar i, Figs. 1, 3, 4 & 6 having a square or other shaped
hole corresponding to the section of the spindle, and with a cone j, Figs. 1, 3, 4 & 6,
at one or both ends, upon its exterior diameter. This conical collar i may be in
one piece, having a slit cut through one of its sides as shown at k, Fig. 4, or, it may
be in two pieces as shewn in Fig. 3.
Also I provide a screwed collar or cap 9, Figs. 1 & 5, having in its internal
diameter a screw thread corresponding to the exterior screw thread upon the neck
of the knob, and also having a conical part at 1, corresponding to the conical
collar i; and, at a point m, corresponding (when in position) to the groove h, upon
the neck of the knob, a hole is made to receive a pin or stud m.
If the conical collar i, is coned at both ends the front internal part of the neck
of the knob, and also the internal part of the screwed collar or cap g, are coned to
suit, but, if only one end of the conical collar is coned and the other end left
square as shewn in Fig. 6, then the front of the neck of the knob may be left

square to suit, or, if desired, instead of the front of the neck of the knob being
left square, the internal conical part at l, may be left square to suit.
When the conical collar i, is placed within the screwed collar g, which in its turn
is screwed on to the neck of the knob, until the hole at m, comes over the groove
in the neck at h; the stud or pin m is then inserted into and beyond the hole into
the said groove, which prevents the screwed collar g, being removed from the neck
of the knob. The groove h, is made somewhat wider, than the thickness of the
stud m, so as to allow of sufficient lateral motion for the conical parts upon the
front of the knob, or the conical part upon the inside of the collar g, or both com-
bined, to act upon the conical collar i, so that the latter may firmly grip the
spindle c.
Thus, when, the knob is passed on to the spindle c, and the screwed collar g is
rotated, the conical collar i, is closed tightly upon the spindle, and thus in a simple
manner the knob is secured to the spindle.
If desired, I may in some instances dispense with the groove h, and also with
the stud or pin m, as this would cheapen the production in manufacture, but, of
course would be attended with the possibility when not in use, of the screwed
collar g, being taken off, and the conical collar lost.
Generally, the hole in the conical collar is found to answer sufficiently well when
made quite plain but I may notch or serrate it if desired, similar to the spindle..
This method of attachment may be applied to knobs or handles of metal china
or wood &o.
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
1st. The securing of door and other similar knobs or handles to their spindles,
by means of a conical collar i, having one or more coned surfaces, such conical
collar being either in one or more pieces and acted upon by a corresponding coned
surface, either upon the neck of the knob, or upon the screwed collar g, or upon
both, the said conical collar being pressed tightly upon and gripping the spindle in
the manner bereindescribed and illustrated upon the drawings.
2nd. The application of a stud pin in the screwed collar g, and a groove in the
neck of the knob, to prevent the removal of the collar g, as hereindescribed and
shewn upon the drawings.
