IMPROVEMENTS IN DOOR OR OTHER KNOBS OR HANDLES AND IN THE METHOD OF ATTACHMENT TO THE SPINDLES THEREOF
Year: 1885

page_text: I, CHRISTOPHER LONGBOTTOM, of 27, Kirkgate, Bradford, in the county of York,
Estate Agent, do hereby declare the nature of the said invention for " IMPROVEMENTS
IN DOOR OR OTHER KNOBS OR HANDLES AND IN THE METHOD OF ATTACHMENT
TO THE SPINDLES THEREOF" to be as follows:-
This invention relates to improvements in door or other knobs or handles and in
the method of attaching the same to their spindles.
In carrying out my invention I employ a square or almost square spindle one end
of which is by preference permanently attached to one of the knobs or handles and
upon the rounded corners of such spindle a screw thread is cut.
The spindle is passed through the door and upon the end projecting through the
door, that is to say, upon the opposite end of such spindle froin that upon which
the permanently fixed knob is placed I place a rose fitting up to the door, within
which rose is formed a flange at right angles to the spindle, in which flange is cut
or formed a key way hereinafter referred to-The rose and flange may be made in
one piece or separate as desired.
Next to the flange and entering it I screw upon the spindle a circular nut which
has a square key way cut in its outer surface in a line parallel with the spindle.
This nut has a flange upon it which fits up to the flange of the rose and is screwed
up to such rose thereby adjusting it to the door. The loose knob in which is
formed a square spindle hole is placed last upon the spindle and has projecting
from its flat face and in a line parallel with the spindle a key which fits into the
key way of the nut and the head of which key passes through the key-way in the
flange of the rose before mentioned; by turning the rose and flange the head of
the key is thereby locked at the back of such flange and the knob is prevented
from being drawn off the spindle.
By this method of securing the knob to the spindle the action of turning the
flange part of a revolution secures the knob to the spindle without the aid of screws
or other fastening devices.
I prevent the rose from turning back (by which the head of the key would be
released) by bringing the key way in the flange opposite to such head, by securing
the rose in position by screws.
By forming a second head upon the key I can use an additional locking flange.
I can also use two keys if desired, placed upon opposite sides of the spindle, and
operating as described.

page_text: I CHRISTOPHER LONGBOTTOM of 27 Kirkgate Bradford in the County of York,
Estate Agent do hereby declare the nature of my invention for IMPROVEMENTS
"
IN DOOR, OR OTHER KNOBS, OR HANDLES AND IN THE METHOD OF ATTACHMENT
TO THE SPINDLES THEREOF and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
My invention relates to improvements in door or other knobs or handles, and in
the method of attaching the same to their spindles.
To carry out my invention, I employ a square or almost square spindle, one end
of which is by preference permanently attached to one of the knobs or handles, and
upon the rounded corners of such spindle a screw thread is cut.
The spindle is passed through the door and upon the end projecting through the
door, that is to say upon the opposite end of such spindle from that upon which the
permanently fixed knob is placed, I place a rose fitting up to the door; within
which rose is formed a flange, at right angles to the Spindle, in which flange is
formed or cut a key way hereinafter referred to. The rose and flange may be
made separate or in one piece as desired. Next to the flange and entering it,
I screw upon the Spindle a nut, which has a key way cut in its outer surface in a
line parallel with the Spindle. This nut has a flange upon it, which fits up to the
flange of the rose, and is screwed up to such rose, thereby adjusting it to the door.
The loose knob, in which is formed a square spindle hole, is placed last upon the
spindle, and has projecting from its flat face, and in a line parallel with the
Spindle, a key which fits into the key way of the nut, and the head of which key
passes through the key way in the flange of the rose before mentioned; By turning
the rose and flange the head of the key is thereby locked at the back of such
flange, and the knob is prevented from being drawn off the spindle.
By this method of securing the knob to the spindle the action of turning the
flange part of a revolution secures the knob to the Spindle without the aid of
screws or other fastening devices.
I may, if necessary prevent the rose from turning back (by which the head of
the key would be released by bringing the key way in the flange opposite to such
head) by securing the rose in position by screws.
By forming a second head upon the key I can use an additional locking flange;
or 1 can use two keys if desired placed upon opposite sides of the spindle and
operating as described.
In order to enable my Invention to be fully understood I will proceed to
describe the same with reference to the accompanying drawings in which Figure 1
represents a sectional elevation of my improved knob or handle, attached to a door,
and an elevation of the fast knob upon the same spindle. Figure 2 a section of
my improved knob-Figure 3 a section of the screw nut which bears the pull
of the knob in the manner hereinafter described. Figure 3a, is a front elevation of

page_text: the same. Figure 4, a sectional elevation of the rose with locking flange herein-
after described, and Figure 44 a front clevation of the same. Figure 5 represents
an, elevation of both knobs attached to a door.
Similar letters refer to similar parts in all the drawings.
The knob A is permanently fixed to the spindle B and is passed through the
square hole in the latch fixed in the door F. Upon the projecting end of the
spindle B the rose E is placed, with its broadest flange close up to the door. The
nut D is then screwed up upon the spindle, until the flange upon this nut fits
closely into the recess formed to receive it in the rose E, and when screwed up
sufficiently to hold the rose firmly in its place without causing unnecessary friction,
this nut Ď occupies the position represented in Figure 1.
When the nut D has been screwed up to the required tightness, the key way L
in such nut must be placed opposite to the key way K which is formed in the
locking flange J of the rose E.
The knob C is then placed upon the spindle B, and at the same time the Key ✪
attached to the knob, and which has a locking head or catch, is passed through
the key ways both in the nut D and in the rose E. When the head of the Key
has been passed through both these key ways, the rose E is turned part of a
revolution, either to the right or to the left, and the head or catch of the key being
at the back of the flange J of the rose E is locked by the turning of such rose and
the knob to which the key is fixed is thereby firmly secured to the spindle, as tho
head of the key G catches the back of the flange J of the rose E, which rose is
held in position by the nut D screwed upon the spindle.
In figure 1 a solid handle is represented, upon the neck of which a brass plate
or flange is secured by having its edge turned over the narrow part of the neck of
the handle H. The Key G is fixed to the flat surface of this brass plate by
rivetting, but the key may be attached to the knob or handle by any other
convenient method.
In some cases I make use of two keys for securing the knob to the spindle, when
two key ways will be required in the nut D and in the locking flange J. I may
also make use of keys with two or more heads in which case two or more locking
flanges will be required.
The locking flauge does not necessarily form a part of the rose, as represented in
the drawings, as it may be formed separately, but used in a similar manner
whereby the turning of the locking flange secures the head of the key as
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
The improvements herein described in door knobs or handles, and in the method
of attachment of the same to their spindles, by means of a key or keys attached to
the loose knob, the nut screwed upon the spindle, and the locking flange which
holds the head of the key by being turned partly round, and bears against the nut,
all substantially as, and for the purpose herein set forth, or any mere modification
of the same.
