Improvements in the Mode of Securing Knobs and Handles to the
Spindles of Door Locks and Latches.
I GEORGE ASHTON BROOKES of 345 Moss Lane East, Manchester, in the County
of Lancaster, Brewer, do hereby declare the nature of this invention to be as
follows:-
My said invention relates to improvements in the mode of securing handles and
knobs to the spindles of door locks, latches and the like, so as to render the same
more easily and accurately fitted and also to prevent them from becoming loose or
detached. At present the most usual mode is to secure such knobs and handles to
the spindle by a small screw passing through the boss of the handle and engaging
with one of a series of countersinks made in the square spindle. The screw has no
great hold on the handle or on the spindle and is very apt to work loose or to have
its point in the countersink "chewed" off by the working of the spindle.
According to my invention I thread the corners of the square spindle end and
form the handle or knob with a square hole to fit the spindle so that it can be pushed
on and adjusted exactly to the thickness of the door or depth of the lock. To keep
the knob or handle in position I screw a jamb nut on the threaded end of the
spindle, which holds the knob exactly to its adjusted position. To box in this jamb
nut I prefer to recess or cup the knob or handle on the outside so as to surround
and shroud the jamb nut. The appearance of the knob or handle is thereby enhanced.
Means might be taken to prevent any possibility of the jamb nut working back,
but at present I do not think such means will be required. A knob or handle fitted
according to my invention is always secure and can never become loose or be pulled
off. By a modification of my invention I might screw on the threaded spindle a
collar which can be screwed forward and adjusted exactly to the required position.
I then push the handle or knob upon the projecting squared spindle end, the boss of
the knob being annularly recessed to receive the screwed on collar. A stout screw
pin or other connecting means is or may be used to connect the knob to the screwed
on collar. The screwed on collar provides for the utmost delicacy of adjustment
while the squared extension of the spindle fitting the hole in the knob prevents any
turning or alteration of the adjusted position of the parts. Under the first or second
modification of my invention, the spindle and knobs can be applied and fitted without
the least trouble, while the removal is equally easily effected.

I GEORGE ASHTON BROOKES of 345 Moss Lane East, Manchester, in the County
of Lancaster, Brewer, 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 and accompanying drawings:-
My said invention relates to improvements in the mode of securing handles and
knobs to the spindles of door locks, latches and the like, so as to render the same
more easily and accurately fitted and also to prevent them from becoming loose or
detached. At present the most usual mode is to secure such knobs and handles to
the spindle by a small screw passing through the boss of the handle and engaging
with one of a series of countersinks made in the square spindle. The screw has no
great hold on the handle or on the spindle and is very apt to work loose or to have
its point in the countersink "chewed" off by the working of the spindle.
My improvements will be best understood by a reference to the accompanying
illustrative sheet of drawings in which,
Fig. 1 shows my improved method of securing the handles to the spindle of an
ordinary door latch, the latch mechanism being omitted as forming no part of my
invention. The left hand portion of the fig. shows the handle in outside view whilst
on the right the handle and milled jamb nut are shown in section.
Fig. 2 is an end view of the handle and spindle shown in Fig. 1.
Fig. 3 shows a modification of my invention.
Referring now to Figs. 1 and 21 thread the corners of the square spindle a and
form the handle or knob b with a square hole to fit the spindle a so that it can be
pushed on and adjusted exactly to the thickness of the door c or to the depth of the
lock. To keep the knob or handle b in position I screw a jamb nut d on the threaded
end of the spindle, which holds the knob exactly to its adjusted position. To box
in this jamb nut I prefer to recess or cup the knob or handle b as shown so as to
surround and shroud the jamb nut. The appearance of the knob or handle is thereby
enhanced. Means might be taken to prevent the possibility of the jamb nut working
back, but at present I do not think such means will be required. A knob or handle
fitted according to my invention is always secure and can never become loose or be
pulled off.
By a modification of my invention and as illustrated in Fig. 3 I might screw on
the threaded spindle a a collar e which can be screwed forward and adjusted exactly
to the required position. I then push the handle or knob b upon the projecting
squared spindle end, the boss of the knob being annularly recessed to receive the
screwed on collar e as clearly shown in the drawing. A stout screw pin for other
connecting means is or may be used to connect the knob or handle 6 to the screwed
on collar e. The screwed on collar provides for the utmost delicacy of adjustment
while the squared extension of the spindle a fitting the hole in the knob prevents
any turning or alteration of the adjusted position of the parts. The handle in this
case need not of necessity be of the formation shown in the drawings. I may
for instance while suitably recessing the boss, use a knob of the ordinary
description.
With a view to further improving the general appearance of the handle fittings
I might prior to fixing the handle, slip on the spindle a and secure to the door c,
any suitable description of ornamental rose.
Under my invention the spindle and knobs can be applied and fitted without the
least trouble, while the removal is equally easily effected.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
(1.) The improved method of securing knobs or handles to the spindles of door
locks, latches and the like substantially as described and as shown in Figs. 1 and 2
of the accompanying drawings.
(2.) The modified manner of securing handles to the spindles of door locks,
latches and the like substantially as described in the foregoing specification and as
illustrated in Fig. 3 of the drawings
