KATE Ross Dressmaker 55 Gratton Road West Kensington, London do hereby declare
the nature of this invention to be as follows:-
The ordinary square spindle to have a thread running along, also a slot or groove
A metal wheel screwing
running longitudaley along one of the four sides of same.
on to spindle is turned out sufficiently one side to allow the insertion of a coggwheel
the said coggwheel having a square centre hole to fit on the four sides of spindle,
Sufficient space is allowed between the inserted coggwheel & rim of screwwheel for
the purpose of fixing a catch working on a pin part of the catch projecting through
a slot on the rim of screw wheel, a spring fixed to the screwwheel presses on to the
said catch, which action causes the catch to lock into the said inserted coggwheel in.
screwing the wheel on to the spindle. The said coggwheel, catch & spring being
covered by a plate fixed to the screwwheel. The other side of wheel is also turned out
sufficient to allow of a plate with a square centre hole to be inserted loosely. The
outer rim of wheel being turned sufficiently thin, to be spun over the said inserted
plate, which plate is fixed to a square metal box. The said plate & box being fixed
into the handle. Inside the metal box is fixed a metal slide running longitudally along,
and being of sufficient length beyond the front of box to allow of it being fixed to
inserted coggwheel; the said slide to fit & slide in groove on spindle. The metal box
to be of such a size to fit and allow spindle to pass though. The whole can now be
For purpose of
screwed on as a complete handle locking itself as it is screwed on.
releasing catch & take off handle from spindle, we fit a ring with a slot inside over the
part of screwwheel which contains the projecting catch. The said ring having a slot
cut right through to allow a pin from the screw wheel to project. The object of the
said pin & slot to prevent the ring turning right or left, beyond a distance sufficient
to press down or release catch.

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
We then
We first take an ordinary square spindle & cut a thread the whole length of it, we
also cut a logitudital slot G the whole length of one of the four sides of spindle as
shown in letter H fig. 3. Fig. 1 a round piece of metal M (according to size required
with thread cut in centre to screw on to square spindle H fig. 3) we then turn out
sufficiently on one side of round metal M to allow of a metal coggwhoel A spring B
and catch C (which works on a pivot) to be inserted, a square hole is cut in centre of
coggwheel A of sufficient size to slide over four sides of spindle H Fig. 3.
turn a shoulder on edge of round metal M to allow of a metal ring (fig. 2) to run on,
one end of catch C projects slightly beyond outer surface of metal shoulder the other
end of catch C falls into teeth of coggwheel A and is kept in that position by spring B.
A pin S is also fixed in metal shoulder. Fig. 2 a metal ring roughed outside with an
indent D and slot E cut inside. We then take the ring and fit it over shoulder of
round metal M (fig. 1) the slot E going over pin S and indent D over one end of
catch C. The ring can be turned right and left as far as slot E will allow; the
indent D when place over one end of catch C does not interfere with catch C position,
but when the ring is turned the thicker portion presses on outer end of catch Û raising
spring Band releasing other end of catch C from teeth of coggwheel A for the purpose
of unscrewing from spindle H (Fig. 3) a plate N with a hole in centre size of cogg-
wheel A with a turned flange, it is then rivetted on to metal M fixing the ring
(fig. 2) sufficient space is allowed for the ring to be turned right or left and covering
coggwheel A spring B catch C. We then take a square metal box K with a round
flange in front and inside of it fix a metal slide F the slide F to run in longitudital
slot G. The slide F to project a sufficient length beyond flange of box to come
slightly beyond outside of metal M, we then fix flange of box K to coggwheel A.
The box K may then be fixed in any ordinary handle of any descripton. A portion
of the plate N is then spun over the round flange of box K and edge of handle,

our said
Having now particularly described and ascertained the nature of
invention and in what manner the same is to be performed we declare what we
claim is
A construction of door and like knobs and other handles fitted with metal cogg-
wheel catch and spring attached to metal box with slide, screwing on and off threaded
longitudital slotted spindle as and for the purpose set forth.
