I HENRY SEPTIMUS WHITEHOUSE of the firm of John Whitehouse and Sons
of Green Street, Birmingham in the County of Warwick, Brassfounders, do hereby
declare the nature of this invention to be as follows:-
My said invention consists in constructing and arranging the parts of door lock
furniture in the manner hereinafter described, whereby the knob of the door lock
is connected to the lock spindle independently of the rose, and pressure upon and
motion of the knob has no tendency to loosen the rose.
I make the loose knob screw on the end of the spindle by means of a concave or
hollow screw in the knob or mount of the knob taking on the screw thread on the
The
angles of the square spindle. 1 construct the rose in the following manner.
foundation plate of the rose consists of a disc screwed to the door in the ordinary
way. In a central opening in the said foundation plate is a compound disc rotating
in the said central opening. The said compound disc consists of two parallel discs
a short distance apart connected at their edges. The inner disc, that is, the disc
which when the rose is fixed is against the door has a slot passing across it of a size
suitable for the square spindle of the lock to pass through but not to rotate therein.
The other or outer disc has a slot parallel to the slot in the inner disc but of larger
diameter and having at one end a circular expansion of such a size as to permit of
the square projection on the mount in which the hollow or concave screw is made
to turn therein. The end of the said slot which has parallel sides is of such a
width that the said projection can enter but not turn in it.

end of the spindle on which the movable knob is to be screwed is passed through
the lock and the rose is passed on to its protruding end. The rose is placed on
the spindle so that the spindle is situated centrally in the circular end of the slot
in the outer disc. The knob is now screwed on the spindle till the face of the
mount of the knob or end of the neck of the knob bears lightly against the outer
disc. The square projection on the mount or neck of the knob has passed by the
screwing of the knob on the spindle, through the front or outer disc, and by sliding
the rose on the spindle the parallel sides of the slot in the front disc are made to
engage with the said square projection and by now screwing the rose to the door
the knob is fixed. That is, the square projection on the mount or neck of the knob
being engaged in the slot, in the front disc the knob can only turn by turning the
compound disc, but the square spindle engaging in the slot in the inner disc the
compound disc can only move through the angle permitted by the follower of the lock.
The knob is thus fixed to the spindle without any strain on the rose and can only
be removed or adjusted on the spindle by unscrewing the rose so as to permit by a
sliding motion of the circular end of the slot in the outer disc being brought around
the spindle of the lock.

Improvements in Door Lock Furniture.
I HENRY SEPTIMUS WHITEHOUSE of the firm of John Whitehouse and Sons
of Green Street Birmingham in the County of Warwick Brassfounders do hereby
declare the nature of my invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
My said invention consists in constructing and arranging the parts of door lock
furniture in the manner hereinafter described, whereby the knob of the door lock
is connected to the lock spindle independently of the rose and pressure upon and
motion of the knob has no tendency to loosen the rose.
I make the loose knob screw on the end of the spindle by means of a concave or
hollow screw in the knob or mount of the knob taking on the screw thread on the
angles of the square spindle. I construct the rose in the following, manner. The
foundation plate of the rose consists of a disc screwed to the door in the ordinary
way. In a central opening in the said foundation plate is a compound disc rotating
in the said central opening. The said compound disc consists of two parallel discs
a short distance apart connected at their edges. The inner disc, that is, the disc
which when the rose is fixed is against the door has a slot passing across it of a
size suitable for the square spindle of the lock to pass through but not to rotate
therein. The other or outer disc has a slot parallel to the slot in the inner disc
but of larger diameter and having at one end a circular expansion of such a size as
to permit of the square projection on the mount in which the hollow or concave
screw is made to turn therein. The end of the said slot which has parallel sides is
of such a width that the said projection can enter but not turn in it.
The parts described are put together and operate in the following manner.
The
end of the spindle on which the movable knob is to be screwed is passed through
the lock and the rose is passed on to its protruding end. The rose is placed on the
spindle so that the spindle is situated centrally in the circular end of the slot in the
outer disc. The knob is now screwed on the spindle till the face of the mount of
the knob or end of the neck of the knob bears lightly against the outer disc. The
square projection on the mount or neck of the knob has passed by the screwing
of the knob on the spindle through the front or outer disc and by sliding the rose on
the spindle the parallel sides of the slot in the front disc are made to engage with
the said square projection and by now screwing the rose to the door the knob is
fixed. That is, the square projection on the mount or neck of the knob being
engaged in the slot in the front disc the knob can only turn by turning the com-
pound disc but the square spindle engaging in the slot in the inner disc the com-
pound disc can only move through the angle permitted by the follower of the lock.
The knob is thus fixed to the spindle without any strain on the rose and can only
be removed from or adjusted on the spindle by unscrewing the rose so as to permit
by a sliding motion of the circular end of the slot in the outer disc being brought
around the spindle of the lock.
I will now proceed to describe with reference to the accompanying drawing the
manner in which my invention is to be performed.
Figure 1 represents partly in elevation and partly in section door lock furniture
containing my improvements for connecting the loose knob to the lock spindle
independently of the rose;
Figure 2 represents a front elevation of the same with the loose knob removed;
Figure 3 represents partly in elevation and partly in section the said door lock
furniture before the loose knob has been screwed home on the spindle and exhibits
the position which the rose and the compound dise of the rose occupy before the
loose knob is fixed to the spindle ;
Figure 4 represents a front elevation of the rose and compound disc in the
position Figure 3;

page_text: Figure 5 represents in side elevation and back elevation the loose knob
detached and
Figure 6 represents in front elevation, section and back elevation the rotating
compound disc of the rose separately.
The same letters of reference indicate the same parts in the several figures of the
drawing.
a is the lock and the door; e is the screwed lock spindle having on one end the
fixed knob e as usual; d is the movable knob having a hollow or concave screw
made in the metal mount for taking upon the screw thread on the angles of the
square spindle c; is the square projection on the mount of the knob for the
purpose hereinafter described; g is the ring like foundation plate of the rose
screwed to the door and h, i is the compound disc situated and capable of rotating
in the central opening in the fixed foundation plate the edge of the said plate
or rose being turned into the depressed or grooved edge or periphery of the
compound disc as represented in Figures 1 and 3 so as to connect the rose and
compound disc together while permitting the latter to rotate in the former. The
said compound disc consists of two parallel iron discs h, connected together in
the manner represented, that is, the outer disc has a brass shell or covering
to which the inner disc is connected, the edge of the said brass shell being formed
into the periphery of the compound disc. In the inner disc or that disc nearest
the door, is a straight slot of a size proper for the spindle c to pass through it but
not to rotate in it. The other or outer disc has in it a slot m parallel to
the slot but of larger diameter and provided at one end with the circular
expansion m². The circular expansion m² is of such a size as to permit of the
square projection on the mount of the loose knob d to turn in it but the said
square projection can enter but not turn in the part m of the said slot having
parallel sides.
The loose knob d is connected to the lock spindle e so as to be independent of and
exert no strain.on the rose in the following manner.
The spindle c having the fixed knob e on its end is passed through the lock and
door and the combined rose g and compound disc h, i is passed onto the protruding
end of the spindle, the said rose being so placed on the spindle that the latter
is situated centrally in the circular end m² of the slot in the outer disc h of
the compound disc as best seen in Figure 4. The loose knob d is now screwed on
the spindle e until the face of the mount of the knob bears lightly against the outer
dise and the square projection on the mount has passed through the front
or outer disc (see Figure 1) and occupies the dotted line position indicated
in Figure 4, that is, occupies the curved enlarged part m² of the slot m in
the said disc of the compound rotary disc of the rose. By pressure upon the con-
nected rose and compound disc in the direction indicated by the arrow in Figure 4
it has a sliding motion given to it on the spindle parallel to the door and made to
occupy the position illustrated in Figure 2. By this cross sliding motion of the
rose on the spindle the parallel sides of the bottom m of the slot in the front
or outer disc are made to engage with the square projection f on the knob
and the bottom of the straight slot in the back disc i is passed onto the spindle.
The rose
is now screwed to the door bas represented in Figures 1 and 2 and the
loose knob d is thus connected to the lock spindle independently of the rose.
will be seen by an examination of Figure 2 that the square projection of on
the mount of the knob d being engaged in the part m of the slot in the front disc h
the knob can only turn by turning the combined or compound disc hi which rotates
within the fixed rose g and that the square spindle being engaged in the slot / in the
inner disc the compound dise can only move through the angle permitted by the
follower of the lock. Thus the pressure upon and motion of the knob d has no
tendency to loosen the rose.
It
In order to detach the knob it is necessary first to unscrew the rose 9 and then
to give a sliding motion to the connected rose and compound disc and bring it into
the position represented in Figure 4 whereby the circular enlarged end m²

page_text: of the slot m in the outer disc h is brought around the lock spindle c so as
to permit of the withdrawal of the square projection f by the rotation of the knob
on the said spindle out of the slot m2.
When the loose knob is made of metal the neck of the knob is screwed internally
and has a square projection similar to the projection f at its front.
Having now particularly described and ascertained the nature of my inven-
tion and the manner in which the same is to be performed I declare that I claim
as my invention of "Improvements in door lock furniture":-
The construction and combination of parts hereinbefore described and illustrated
in the accompanying drawing for connecting the loose door knob to the lock spindle
independently of the rose; that is to say, making the rose of a ring-like foundation
plate screwed to the door and a compound slotted disc connected to and capable
of rotating in the central opening in the foundation plate or rose; and the use with
the said rose and compound slotted disc of a square projection on the mount or neck
of the knob, the lock spindle and square projection on the knob being engaged with
the slotted compound disc of the rose in such a manner that on the turning of the
knob the said compound disc moves in the rose only through the angle permitted
by the follower of the lock, the several parts being combined and acting sub-
stantially as described and illustrated.
