Year: 1884

page_text: I EDWARD VERNON BAILEY of N° 174 Great Hampton Row Birmingham in
the County of Warwick Brassfounder do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN CONNECTING DOOR AND OTHER KNOBS TO AND
ADJUSTING THEM ON THEIR SPINDLES" to be as follows:-
My Invention consists of the construction and combinations of parts hereinafter
described for connecting door and other knobs to and adjusting them on their
spindles.
My Invention is particularly applicable to the connecting and adjusting of the
moveable knobs of lock spindles but is also applicable to the connecting and
adjusting of the knobs of cupboard turn spindles and the knobs of other spindles.
In applying my Invention to a pair of door knobs and their spindle I use a
fixed knob on one end of the spindle and a moveable knob on the other and
screwed end of the spindle. The hole in the neck of the moveable knob is
screwed at the back with a screw thread for taking upon the screwed end of the
spindle and the front of the said hole in the neck is square or angular. For
determining the position to which the moveable knob can be passed onto the
screwed end of the spindle I use a sliding collar having a square or angular bush
at its front of a size suitable for the square or angular hole in the neck of the
said moveable knob to take upon. Or the sliding collar may have lugs on its edge
instead of a bush at its front the edge of the neck of the knob having cross
notches for engaging with the lugs on the collar. The rose to be secured at the
fixed knob having been passed onto the neck of the fixed knob the screwed end
of the spindle is inserted through the door and lock and on the protruding
screwed end of the spindle the sliding collar herein before described is passed until
it reaches the door. The moveable knob is now screwed on the end of the spindle
and the square hole in the neck of the said knob made to take upon the bush on
the sliding collar or the cross slots in the neck take upon the lugs on the collar.
The moveable knob is thereby prevented by the collar from rotating on the spindle.
The spindle being now pulled backwards by the fixed knob the collar at the
moveable knob is made to bear closely against the lock and is maintained in that

place the moveable knob cannot be withdrawn from the spindle.
The rose on the neck of the fixed knob is next screwed on the fixed rose plate

page_text: I EDWARD VERNON BAILEY of N° 174 Great Hampton Row, Birmingham in
the County of Warwick, Brassfounder do hereby declare the nature of my
Invention for "IMPROVEMENTS IN CONNECTING DOOR AND OTHER KNOBS TO AND
ADJUSTING THEM ON THEIR SPINDLES" and in what manner the same is to bo
performed to be particularly described and ascertained in and by the following
statement
My Invention consists of the construction and combinations of parts herein-
after described for connecting door and other knobs to and adjusting them on their
spindles.
My Invention is particularly applicable to the connecting and adjusting of
the moveable knobs of lock spindles but is also applicable to the connecting
and adjusting of the knobs of cupboard turn spindles and the knobs of other
spindles.
In applying my Invention to a pair of door knobs and their spindle, I use
a fixed knob on one end of the spindle and a moveable knob on the other and
screwed end of the spindle. The hole in the neck of the moveable knob is
screwed at the back with a screw thread for taking upon the screwed end of
the spindle and the front of the said hole in the neck is square or angular. For
determining the position to which the moveable knob can be passed onto the
screwed end of the spindle, I use a sliding collar having a square or angular
bush at its front of a size suitable for the square or angular hole in the neck
of the said moveable knob to take upon. Or the sliding collar may have lugs
on its edge instead of a bush at its front, the edge of the neck of the knob
having cross notches for engaging with the lugs on the collar. The rose to
be secured at the fixed knob having been passed on to the neck of the fixed
knob the screwed end of the spindle is inserted through the door and lock and
on the protruding screwed end of the spindle the sliding collar herein before
described is passed until it reaches the door. The moveable knob is now screwed
on the end of the spindle until it touches the sliding collar and the square hole in
the neck of the said knob made by pressure to take in the bush on the sliding
collar or the cross slots in the neck take in the lugs on the collar. The moveable
knob is thereby prevented by the collar from rotating on the spindle. The collar
at the moveable knob is maintained in its position by means of a forked rose plate
(that is, a plate screwed on its edge or middle and having a radial slot extending
from its middle to its circumference) which rose plate is passed onto the spindle by
its forked part between the neck of the moveable knob and the door and screwed
to the door. So long as the rose plate is in its place, the moveable knob cannot be
withdrawn from the spindle. The rose on the neck of the moveable knob is next
screwed on the fixed rose plate and the spindling of the knobs is complete.
The forked plate may be applied either to the moveable knob or fixed knob.
In attaching knobs to cupboard turn spindles I proceed in the manner already
described excepting that in place of a forked rose plate I use a similar forked plate
which is fixed to the inside of the cupboard door between the arm of the turn and
the said door.
Figure 1 of the accompanying Drawings represents partly in elevation and
partly in horizontal section a pair of door knobs the moveable knob of which is
connected to the spindle according to my Invention. Figure 2 is a section of the
moveable knob taken on the line a Figure 1; Figure 3 represents the moveable
knob after the sliding collar or key has been engaged with the recess in the neck

page_text: of the moveable knob, but before the forked rose plate has been put in its place;
Figure 4 represents in front elevation and Figure 5 in side elevation the moveable
knob detached; Figure 6 represents the sliding collar separately and Figure 7 the
forked rose plate and rose detached.
b is the fixed knob on one end of the spindle d and c is the moveable knob on
the other and screwed end of the said spindle. The hole e in the neck of the
moveable knob c is screwed as usual for taking upon the screwed end of the
spindle d; f is the recess at the front of and crossing the neck of the moveable
knob c as best seen in Figures 4 and 5; g is the sliding collar or key for
determining the position of the moveable knob c on the spindle d and for fixing
the said knob. The said sliding collar or key g is of an oblong figure and has a
square hole in its middle for sliding upon the spindle d and the said collar or key
has a shape the counterpart of the recess f in the neck of the moveable knob c
into which recess it is to be passed. Instead of the oblong sliding collar or key g,
a square collar or key may be used, the recess in the neck of the knob having a
corresponding figure; h is the forked rose plate having a radial slot i in it
extending from its middle to its circumference (see Figure 7). The said rose plate h, i
is screwed to the door at the moveable knob c for securing the sliding collar or
key in its recess f in the moveable knob. The rose plate h has at its outer face
a screwed shoulder k for the rose / to screw upon. The said rose when screwed.
in its place upon the rose plate h covers the said rose plate and conceals the screws
by which it is fixed to the door.
In connecting the moveable knob c to and adjusting it on its spindle d by the
appliances constituting my Invention I proceed as follows:-
The rose m to be secured at the fixed knob b having been passed onto the neck
of the said fixed knob, the screwed end of the spindle d is passed through the door
and lock and on the protruding screwed end of the spindle the sliding collar or
key g is passed until the bush at its front bears against the door. The moveable
knob c, with the rose on its neck, is now screwed on the end of the spindle d
until the neck of the knob abuts against the sliding collar or key g, with the
recess opposite the said sliding collar or key. After the knob c has been screwed
close to the sliding collar or key g in the position described, the said knob is
pressed towards the door and the recess f in the neck of the knob made to take
upon the sliding collar or key g. The moveable knob c is thus prevented by the
collar or key g from rotating on the spindle. The knob b is now pressed so as to
move forward the spindle d and bring the knob c and the engaged collar g into the
position represented in Figure 3, thereby leaving a space between the neck of the
knob c and the door equal to the thickness of the collar g. The forked rose
plate is next passed onto the spindle and into the space between the neck of the
knob and the door, the slot i in the rose plate fitting loosely the bush on the fixed
collar gas represented in Figure 1. The forked rose plate is thus made to cross
the collar or key g and hold it in the recess f and so long as the said rose plate is
in its place the moveable knob cannot be withdrawn from the spindle. The rose
plate having been fixed by screws to the door it is covered and concealed by
screwing the rose upon the said rose plate as represented in Figure 1.
rose m of the fixed knob having been screwed to the door in the ordinary way the
spindling of the knobs is completed.
The
The forked rose plate (or the forked plate hereinafter described) may be used at
the fixed knob instead of at the moveable knob. In this case after the recess in
the neck of the moveable knob has been engaged upon the sliding collar or key the
rose plate or forked plate is passed into the space between the collar of the fixed
knob and the door or lock so as to maintain the moveable knob in its position
against the door and the key or collar in the recess in the said moveable knob.
Figure 8 represents in side elevation partly in section a pair of door knobs for a
rim lock the moveable knob of which is furnished with a forked plate instead of a
forked rose plate and the sliding collar has lugs on its edge; Figure 9 represents an
elevation of the face of the moveable knob; Figure 10 the sliding collar or key

page_text: having lugs on its edge; Figure 11 the forked plate and Figure 12 the rose used to
cover and fix in its place the forked plate.
The moveable knob c has in its face a recess f of the shape represented in
Figure 9 for receiving the sliding collar or key g and its lugs g, g². After the
recess in the moveable knob c has been engaged upon the sliding collar g, gå in
the manner herein before described, the forked plate n, Figure 11, is passed onto
the spindle and into the space between the face of the moveable knob c and the
door so as to fix the sliding collar or key g, gå in its place in the knob. The
rose (shown separately in Figure 12) is then fixed to the door by screws. By
the fixing of the rose p the forked plate n is secured in its place and the spindling
of the knob completed.
Figure 13 represents in side elevation and Figure 14 in back elevation my
improvements applied to the spindle of a cupboard turn; Figure 15 represents the
forked plate; Figure 16 the arm or latch of the turn and Figure 17 the trough
shaped nut for screwing on the spindle.
The
q is the screwed spindle carrying the knob of the cupboard turn; r is the arm
or latch of the turn having a square hole in it for sliding on the square spindle q,
and s is the nut having turned up edges for the latch or arm of the turn to
engage with. The said trough shaped nut has a tapped hole 8 at its middle.
latch or armr having been passed by a sliding motion along the spindle q until it
bears against the door, the trough shaped nuts is screwed upon the end of the
spindle until it touches the latch when outward pressure upon the knob causes
the trough shaped nut 8 to engage with the latch and thereby fix its position on
the spindle. The forked plate t is next passed onto the spindle and into the space
between the latch r and door so as to secure the said latch in the trough shaped
nut 8.
The forked plate t is fixed to the door by screws.
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 The combination in the ways herein before described and illustrated in
Figures to 12 both inclusive of the accompanying Drawings, of the sliding
collar g or g, g and the forked rose plate h, i, k, or forked plate n, for adjusting the
moveable knob on and fixing it to the spindle.
Secondly-The modification of the parts as applied to cupboard turn spindles
herein before described and illustrated in Figures 13, 14, 15, 16 and 17 of the
accompanying Drawings.
