Improved Method of Securing Door Handles on their Spindles.
I, WILLIAM WARD, of High Street, Portishead, Somerset, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention consists in an improved method of securing door handles on
their spindles.
According to this invention a spring of india-rubber surrounds the spindle in
front of the neck of the fixed knob and is preferably contained within a metal
thimble the inner end of which is adapted to bear against the door.
The other end of the spindle, that is to say, the end which takes the removable
knob is round up to a suitable length from the end. Beyond such point the spindle
is square or rectangular, as usual. The removable knob is adapted to be screwed
on the round part of the spindle. In the neck of the removable knob are teeth.
.Between the door and the removable knob is a sleeve free to slide axially on the
square or rectangular part of the spindle, but not free to turn except with the
spindle. In the outer end of the sleeve are recesses corresponding to the teeth in
the neck of the knob.
When the spindle has been passed through the door the sleeve aforesaid is slid
on the spindle.
The spring aforesaid is then compressed by exerting an inward pressure on the
fixed knob. The removable knob is then screwed up until the tops of the teeth
in the neck come into contact with the corresponding projections of the recesses.
The knob is moved further round until the teeth are clear of the tops of the
projections.
The pressure on the fixed knob is then withdrawn and the teeth of the
removable knob are drawn, by the action of the spring, into the recesses in the
sleeve.
The sleeve and the knob thus become locked together and turn with the spindle.
Instead of an india-rubber spring, a spiral steel spring may be used.

COMPLETE SPECIFICATION.
Improved Method of Securing Door Handles on their Spindles.
I, WILLIAM WARD, of High Street, Portishead, Somerset, Engineer, do
hereby declare the nature of this invention aud in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to door handles, and consists in improvements in aud
relating to the attachment of such handles to their spindles.

relating to the attachment of such handles to their spindles.

page_text: According to one arrangement comprised in this invention a spring surrounds
the spindle at that end at which is carried the fixed knob. The spring, which
may be of india-rubber, but is preferably a spiral spring of steel, bears at one end
against the neck of the fixed knob, and, at the other end, either against the door,
or door lock or against the end of a thimble carried loosely on the spindle which
latter is throughout a part of its length square or rectangular in section. From
the other end up to the point at which the spindle is of square or rectangular
section the spindle is round and screw-threaded.
The removable knob is adapted to be screwed on the round part of the spindle.
Between the door and the removable knob is a sleeve which when slid on to
the square or rectangular part of the spindle, which it fits, can only turn with the
spindle. The outer end of the sleeve is toothed and recessed as also is the
removable knob.
When the spindle has been passed through the door and the lock, the sleeve
aforesaid is slid home on the spindle and the removable knob is screwed on and
up until the neck comes into contact with the sleeve. The spindle is then made to
protrude still further through the sleeve by compressing the spring at the fixed
knob end. The removable knob is now further screwed up to the sleeve and when,
after so doing, the teeth of the removable knob are brought opposite the recesses
in the sleeve the spring at the fixed knob end is allowed to rebound. The teeth
on the neck of the removable knob enter the recesses in the sleeve, and the
removable knob and sleeve become interlocked.
Instead of locking by means of teeth formed in the neck of the removable
knob, as above described, locking is, under a modification, effected by means of
pins fixed into the neck of the removable knob and engaging with correspondingly
shaped cavities in the sleeve.
Referring to the accompanying sheets of drawings,
Fig. 1 illustrates one arrangement comprised in this invention.
Between the neck of the fixed knob a and the inner end of a thimble b
loosely carried on the spindle c is a spiral spring of steel. The spindle c
is square or rectangular in section from the fixed knob a up to the point c
from whence to the other end the spindle is round and screw-threaded.
Fig. 2 is a view of the spindle as shown apart.
On the square or rectangular part of the spindle c fits a sleeve e, shown apart in
side view at Fig. 3 and in outer end view at Fig. 4 from which latter it will be seen
that the channel through the sleeve corresponds in sectional shape to the square
or rectangular part of the spindle c. At its inner end the sleeve e bears against
a rose for against the door or door lock. At its outer end the sleeve e has teeth e
and recesses. The neck of the removable knob g has similar teeth g' and
recesses g³. A detached inner end view of the knob g is shown at Fig. 5. The
knob is adapted to be screwed on the screw-threaded part of the spindle c.
When the spindle c has been passed through the door and lock, the sleeve e is slid
on from the rounded end until it bears at its inner end against the rose for
against the lock or door if a rose is not used. The removable knob is then
screwed up. Compression of the spring d, by an inward pressure exerted on the
fixed knob a, extends the spindle further beyond the outer end of the sleeve e and
when, after the knob g has been screwed up to a sufficient extent the pressure on
the knob a is withdrawn, the spring d rebounds and. the teeth e¹ of the sleeve e
enter the recesses 9 of the neck of the knob 9 and thus the sleeve e and
knob g become interlocked so that when the latter is turned, the spindle o turns
with it.
g
At Figs. 6 to 8 inclusive, is shown a modification according to which inter-
locking of the sleeve e and knob g is effected by pins or studs screwed or
otherwise fixed in the neck g' of the knob, and taking into cavities e³ made for
their reception in the sleeve e. Fig. 6 is a view of the outer end of the sleeve.
Fig. 7 is a part section and part elevation, and Fig. 8 is an inner eud view of the
knob g.

page_text: 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. A method of securing door handles on their spindles; said method consisting
of interlocking, by the rebound of a previously compressed spring, of one of the
handles to a sleeve carried on the spindle and capable, when in place, of turning
only with the spindle, substantially as hereinabove described.
2. Means for securing door handles ou their spindles; said means consisting of
the spring d, or its equivalent, situated between the fixed knob a and the door or
door lock, the partly rectangular and partly round and screw-threaded spindle c,
the sleeve e shaped to fit the angular part of the spindle and to interlock with
the neck g of the knob g; the latter being fitted to be screwed on the rounded
part of the spindle; all constructed, arranged and operating, substantially as
hereinbefore described with reference to Figs. 1 to 5 inclusive of the drawings.
3. The modified method for interlocking the removable knob g and the sleeve e,
consisting of pins or studs / fixed in the neck of the removable knob, and cavities
to receive the same formed in the sleeve, substantially as hereinbefore described
with reference to Figs. 6 to 8 inclusive of the accompanying sheets of illustrative
drawings.
