IMPROVEMENTS IN ATTACHING DOOR AND OTHER KNOBS TO SPINDLES
Year: 1885

page_text: We JOHN WALKER and HENRY BAXTER WORSEY both of N° 14 Edmund Street
Birmingham in the County of Warwick Hardware Factors and Manufacturers do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN ATTACHING
DOOR AND OTHER KNOBS TO SPINDLES "
to be as follows :-
Our invention consists of improvements on an invention for which Letters Patent
we granted to John Walker one of the present applicants on the 12th day of July
1871 N° 1823.
In the patented invention referred to the adjusting and fixing of the moveable
knob on its spindle is effected by an adjustable oblong key screwed on its curved
ends the said key screwing on the end of the spindle. The shoulder of the move-
able knob which slides on the spindle has a cross recess for taking upon the oblong
key. The periphery of the shoulder of the moveable knob is screwed and by
means of a loose screwed collar on the neck of the knob screwing upon the shoulder
of the said knob and upon the screwed ends of the key the knob is fixed to the
spindle. According to our invention we dispense with the loose screwed collar
together with the screwed shoulder of the knob and screwed end of the key for
fixing the moveable knob to the key and use for that purpose the rose of the
moveable knob the said rose being constructed and combined with the other con-
necting appliances in the manner hereinafter described. We use the cross recess in
the shoulder of the knob as before described for taking upon the adjustable key
but the periphery of the said shoulder is plain and we connect to the said shoulder
a rose capable of a partial rotation thereon. In this rose is a cross opening of the
same size and shape as the cross recess in the shoulder of the knob. By turning
the connected rose in one or other direction through about a quadrant the opening
in it can either be made to coincide with the recess in the shoulder of the knob or
cross the said recess. On the opposite longer sides of the opening in the rose
curved slots of different lengths are made for a stop pin on the face of the shoulder
of the knob to take into. The rose is connected to the shoulder of the knob by a
flange on the rose working in a groove, in the said shoulder the ends of the key
being stepped to fit upon the flange of the rose.
The parts are used in the following manner. The key having been adjusted on
the spindle the moveable knob carrying the connected rose (the opening in the rose

page_text: and the recess in the shoulder of the knob coinciding) is pushed by a sliding
motion onto the spindle until the recess in the shoulder of the knob takes upon
the key which key completely fills the recess but the inner face of the key is clear
of the rose. The rose is next turned upon the knob through about a quadrant and
fixed to the door by screws. The opening in the fixed rose is thereby made to
cross the key and hold the latter in the recess in the knob and thus connect the
knob through the said key to the spindle. When the knob is turned in either
direction for withdrawing the latch the stop pin on the shoulder of the knob travels
in the longer curved slot in the rose. As the angle through which the knob turns
is less than that necessary to bring the key coincident with the cross opening in
the rose it follows that the turning of the knob does not interfere with the parts
by which the knob is attached to the spindle.
In order to detach the moveable knob it is first necessary to unfasten the rose
and turn it back until the stop pin enters the short curved slot in the rose. The
opening in the rose now coincides with the cross recess in the knob and the latter
can be withdrawn from the spindle.

page_text: We JOHN WALKER and HENRY BAXTER WORSEY both of N° 14 Edmund Street,
Birmingham, in the County of Warwick Hardware Factors and Manufacturers, do
hereby declare the nature of our Invention for "IMPROVEMENTS IN ATTACHING
DOOR AND OTHER KNOBS TO SPINDLES" and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
Our invention consists of improvements in an invention for which Letters Patent
were granted to John Walker, one of the present applicants, on the 12th day of
July 1871, No 1823.
In the patented invention referred to, the adjusting and fixing of the moveable
knob on its spindle is effected by an adjustable oblong key screwed on its curved
ends, the said key screwing on the end of the spindle. The shoulder of the move-
able knob which slides on the spindle has a cross recess for taking upon the oblong
key. The periphery of the shoulder of the moveable knob is screwed and by
means of a loose screwed collar on the neck of the knob-screwing upon the
shoulder of the said knob and upon the screwed ends of the key the knob is fixed
to the spindle.
According to our invention we dispense with the loose screwed collar together
with the screwed shoulder of the knob and screwed end of the key for fixing
the moveable knob to the key and use for that purpose the rose of the moveable
knob, the said rose being constructed and combined with the other connecting
appliances in the manner hereinafter described. We use the cross recess in the
shoulder of the knob as before described for taking upon the adjustable key but
the periphery of the said shoulder is plain and we connect to the said shoulder
a rose capable of a partial rotation thereon. In this rose is a cross opening of the
same size and shape as the cross recess in the shoulder of the knob. By turning
the connected rose in one or other direction, through about a quadrant, the opening
in it can either be made to coincide with the recess in the shoulder of the knob or
cross the said recess. The rose is connected to the shoulder of the knob by a
flange on the rose working in a groove in the said shoulder, the ends of the key
being stepped to fit upon the flange of the rose.
The parts are used in the following manner. The key having been adjusted on
the spindle the moveable knob carrying the connected rose (the opening in the rose
and the recess in the shoulder of the knob coinciding) is pushed by a sliding
motion onto the spindle until the recess in the shoulder of the knob takes upon
the key which key completely fills the recess, but the inner face of the key is clear
of the rose. The rose is next turned upon the knob through about a quadrant
and fixed to the door by screws. The opening in the fixed rose is thereby made to
cross the key and hold the latter in the recess in the knob and thus connect the
knob through the said key to the spindle. As the angle through which the knob
turns is less than that necessary to bring the key coincident with the cross opening

page_text: in the rose it follows that the turning of the knob does not interfere with the
parts by which the knob is attached to the spindle.
In order to detach the moveable knob it is first necessary to unfasten the rose
and turn it back until the opening in the rose coincides with the cross recess in the
knob when the latter can be withdrawn from the spindle.
Figure 1 of the accompanying Drawing represents the moveable knob of a pair
of door knobs connected to its spindle according to our invention and Figure 2
represents the same with the connected rose turned through a quadrant or into the
position proper for permitting of the moveable knob being passed onto or with-
drawn from the spindle; Figure 3 represents the spindle detached from the door
and the moveable knob detached from the spindle, the said moveable knob being
represented partly in longitudinal section: Figure 4 represents in back elevation

key separately; Figure 11 represents the said key in section and Figures 12 and 13.
represent the two parts of the adjustable key.
.
The same letters of reference indicate the same parts in the several Figures of
the drawing: a is the fixed knob and b is the spindle, one end of which is screwed
on its angles as usual; c is the moveable knob which slides upon the said spindle b;
is the adjustable key screwed internally for screwing upon the screwed end of
the spindle b; e is the connected rose of the moveable knob c the said rose e being
secured to the metallic shoulder ca of the moveable knob by turning a flange on
the rose over the said shoulder c² so that while the rose can rotaté upon the
shoulder it is incapable of being disconnected therefrom; f is the cross recess in
the shoulder of the knob c for taking upon the adjustable key d on the spindle:
To the front of the rose e a plate e² (shown separately in Figure 9) is connected.
In the rose plate e² is a cross opening e³ of the same size and shape as the cross
recess in the shoulder of the knob c. By turning the connected rose e in one or
other direction through about a quadrant its cross opening e³ can either be made
to coincide with the recess fin the shoulder of the knob as represented in Figure 5,
or cross tlie said recess as représented in Figure 4. The ends of the adjustable
key d are stepped as seen in the Drawing, the stepped ends when the key passes
into the recess in the shoulder of the knob engaging with the flanges inside the
rose (see Figures 1 and 2). On the front of the adjustable key d is a flanged
collar d the flange of which when the moveable knob has been passed to its
position on the spindle abuts against the door. The said adjustable key is capable
of turning within the said collar d² for accurately adjusting the position of the key
with respect to the cross slot e³ and recess f in the rose and moveable knob.
In attaching the moveable knob c to the spindle b, the said spindle with the
fixed knob a on one end, is passed through the door g and on the protruding
screwed end of the spindle the adjustable key d, d² is screwed until its flanged
collar abuts against the face of the door as represented in Figures 1 and 2. The
moveable knob c carrying the connected rose (the opening e³ in the said rose and
the recess in the shoulder of the knob being made coincident) is pushed by a
sliding motion onto the spindle b until the recess fin the shoulder of the knob
passes onto the key d'on the spindle which key completely fills the said recess fin
the knob as represented in Figures 1 and 2. The parts are now in the positions
represented in Figures 2 and 5. The rose e is next turned upon the knob c through
about a quadrant. The opening e³ in the rose is thereby made to cross the key d
as illustrated in Figures 1 and 4 and hold the said key in the recess f in the knob
in consequence of the uncut away part of the plate e² of the rose being brought

page_text: in front of the ends of the key. After the rose e has been turned as described so
as to lock the key d to the combined rose and knob e, c, the said rose e is fixed to
the door g by screws at h, h as represented in Figure 1. The adjusted moveable
knob is thus fixed to the spindle. The accurate adjustment of the position of the
key d so as to bring it opposite the cross opening and recess in the rose and knob,
is effected by slightly turning the key upon the spindle, the said key rotating
without the abutting flanged collar d².
As the angle through which the moveable knob c turns to operate the latch is
less than that necessary to bring the key d, which virtually forms a part of the
said knob, coincident with the cross opening e³ in the now fixed rose, the operating
of the latch does not interfere with the attaching parts of the knob.
In order to remove the knob c from the spindle the rose e is unfastened from the
door and the said rose is turned until its cross opening e³ coincides with the cross
recess in the knob c when the said knob can be withdrawn from the key d and
detached from the spindle as represented in Figure 3.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we delare that we
claim as our Invention of "Improvements in attaching door and other knobs to
spindles"
Attaching the moveable knob to its spindle by the combination of the following
parts, namely, the cross recess f in the shoulder of the knob, the adjustable
screwed key d, da and the connected rose e, e², having a cross slot or opening e in
its front face, the said parts f, d, d² and e, e², ea being constructed, arranged and
used substantially as hereinbefore described and illustrated in the accompanying
Drawing.
