GEORGE BECK, Salesman, 65, St. Anne's Hill, Wandsworth, S.W., do hereby
declare the nature of this invention to be as follows:--
Knob secured one end of spindle, the other end of spindle to be slotted & drilled
with holes. The tail of L or T pin laying in slot & head of same projecting
through hole other side of spindle. The other knob & rose to be in one piece but
rose to revolve on neck of knob. The rose on knob to be hollow on inside to allow
for slotted plate which is attached to rose. Through slot in said plate the L or

[mprovements in Attaching Door Knobs to Spindles.
GEORGE BECK, Salesman, 42, St. Anne's Hill, Wandsworth, London, S.W. (late of
65, St. Anne's Hill, Wandsworth, S.W.), do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
I take an ordinary square door spindle A with one knob A¹ securely fixed to it &
make a groove B lengthways on one side of the spindle of a certain length & depth.
I then bore holes C through the grooved part of the spindle of an equal distance
apart as shewn in Fig. 1.
AT or cross-shaped pin E is then made (Fig. 2) the short end of which passes
into one of the holes C the shoulders E¹ of pin resting in groove of, & flush with
top of, aforesaid spindle leaving one part E2 projecting above spindle (Figs. 3 & 4).
The pin is so made that by reversing same in any one of the holes, any distance
can be taken up in order to fit doors of different sizes & to prevent loose play when
fixed to the door. I now make a door-knob F with revolving rose F1 attached, the
knob having a square hole F2 in neck of same to fit spindle so that knob can slide on
to the spindle-Fig. 5. To the revolving rose I attach a flat plate G with a round
hole G¹ & slot G2 cut in centre with screwholes G³ the round hole being of the
required size to admit of free play to spindle Fig. 6. By this means a hollow H or
chamber is formed between the said plate & the neck of knob sufficiently large to
allow play of the projecting pin before described.

page_text: To fix this furniture to the door, I pass the spindle with knob fixed one end first
described through the door, so that spindle with the holed & grooved part projects
other side of door. I then drop the aforesaid T or cross-shaped pin into hole in
spindle nearest door, but if this should not be the proper distance to allow for the
rose of knob to pass between the projecting part of pin & the door, I reverse
the aforesaid pin thus taking up or allowing the necessary distance for the fixing
of door-knob & rose to the door. The spindle with handle attached (Fig. 1) is now,
by means of the projecting pin, held in the door. The pin now being in proper
position in spindle, I take the knob-rose with slotted plate attached & slide same on
the projecting spindle, the slotted plate & rose passing over part of the projecting
pin until the rose & plate rests flush against door. The projecting part of pin is
now within the hollow or chamber formed by the aforesaid slotted plate & the knob-
rose. The rose (F) with slotted plate (G) attached which revolves on the neck of
knob is then turned half a revolution (Fig. 7) and is screwed to door, the said rose &
slotted plate having the necessary holes for this purpose. The furniture is now
a fixture to the door as shewn in Fig. 8.
By another arrangement, I can use the knob-rose without the slotted plate being
fixed to rose, by having a smaller slotted & holed plate made so that after the
aforesaid pin has been placed in position, the said loose & slotted plate is slid over
the pin & turned half a revolution and tacked to the door the plate having two holes
for this purpose. The knob-rose is then slid on the spind'e until the rose is flush
with door & rose is then screwed to door to complete fixture.
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:
1. The fixing of door-knobs to the spindles without the use of screws or washers by
means of T or cross-shaped pin & a slotted & holed plate fixed to a revolving rose on
knob as described herein.
2. The fixing of door-knobs to spindles without the use of screws by means of
a T or cross-shaped pin & a loose slotted & holed plate utilising any ordinary
knob-rose.
