Improvements in Means for Fastening Handles for Doors and the like.
I, AMON KELLETT, Warwick House, Warwick House Estate. Worthing, Sussex,
Cashier, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in means for fastening handles for doors
and the like. In carrying out my object I provide the handle with a spring catch
which engages in notches or a rack formed upon the spindle or bar which passes
through the door, the notches being so shaped as to enable the handle to be
operated on to the spindle and the spring catch then secures same in position, said
spring catch engaging in the notches aforesaid. These notches may be of any
suitable size and the distance of the notches upon the spindle may be varied so
as to enable the handle to be adjusted upon same.

Improvements in Means for Fastening Handles for Doors and the like.
I, AMON KELLETT, of Warwick House, Warwick Gardens, Worthing, in the County
of Sussex, Cashier, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertaine
in and by the following statenient :-
My invention relates to an improved method of easily fixing and securing a knob
or handle on its spindle, and may be employed for actuating door locks or catches,
and the like, and for securing terminals and mounts for bedsteads and cots.
The accompanying drawing shows how it may be applied to a spindle, such as
are commonly used for actuating door locks or catches.
Referring to Fig. I, A is a square spindle, made of any suitable material; on
one end of the said spindle A, a knob or handle B of any suitable material, is rigidly
secured in any well known or suitable manner. At the other end of the said
spindle A, is a removable knob or handle C, made of any suitable material, and
affixed in the manner described as follows:-
On the said spindle A, a number of ratchet teeth or serrations are made, as
shown at D, D, the knob or handle is made with a square hole E. E¹, so as to
casily slide on the spindle A. On the neck of the said knob C. I place a spring
clip or band F, F, made of steel or other suitable material, having a pin or

freely.
A.
The said pawl H goes through a hole J, J', in the neck of the knob, and engages
in the ratchet teeth D, on the spindle
The clip is made as shown in Figs. III and IV; the end of the pawl, where it
engages in the ratchet teeth, is made bevel, to suit the angle of the ratchet teeth,
and so as to go on the spindle
The other side of the pawl is made square so as to form a back stop, and thus
prevent the knob from coming off the spindle, in fact performing the function
of a ratchet and pawl, the spring clip F keeping the pawl always engaged in the
ratchet teeth D, and being also sufficiently elastic to allow the said pawl to move
up and down over the points of the teeth, and thus to slide forward over the
spindle.
The end of the spindle A, may be bevelled as shown at K, so as to allow the
pawl to enter freely and engage the teeth.
So as to obtain a more delicate and fine adjustment in fixing the knob, the said
ratchet teeth or serrations D, may be on two opposite sides of the spindle A, and
so made that the pitch of the said teeth, alternate on opposite sides of the spindle,
as shown; that is to say, the points of the teeth on one side, are half way between
the points of the teeth on the other side: so that if a slightly longer or shorter
distance is required between the handles at each end of the spindle, the removable
knob . may be placed so that the paw! F, engages in the ratchet teeth on the one
side or other of the spindle, and thus making the said distance longer or shorter
as required.
I can if desired, also place as shown at L, a washer made of india-rubber or some
such elastic material, or else a concave or other suitable form of spring metallic
washer may be used, so that when the knob or handle is being fixed in position,
it may be pushed against the said spring washer and thus compressing the
spring washer slightly, until the spring pawl or catch H, engages in one of the
ratchet teeth, thus securing the knob or handle firmly on its spindle.
The clip is made so as to spring over the neck of the knob C. and so that the
clip may be easily removed, the neck of the knob is indented, as shown at M, M,
so that a bradawl or some such similar tool, may be inserted under the spring
clip, to force it off the knob, thus disengaging the pawl H. and allowing the knob
to be easily detached from its spindle.
If desired, I can of course place a removable knob as at C, F, and L, at both ends
of the spindle A, instead of a rigidly fixed knob at one end, by having a separate
spindle, and having the ratchet teeth at both ends of the spindle.
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 combination of the removable spring clip F, and pawi H. on the knob C,
with the matchet teeth or serrations D, on the spindle A, so as to easily fix the
knob on its spindle; substantially as described and illustrated.
(2) The combination of the ratchet teeth D, the clip F, and pawl I, with the
spring washer L, so as to firmly secure the knob on its spindle; substantially as
described and illustrated.
