be as follows :--
This invention which relates to improvements in the method of fixing handles to
locks or doors has for its object to effect the fixing of handles in a simpler and more
efficient manner than hitherto.
In carrying out our said invention we provide a square spindle screwed at both
ends on the edges of the square or otherwise. We also provide a half or any
section of a handle with square socket in the centre and recessed or checked at the
circumference at the point where the other half or section of the handle is made to
metre. We also provide the other half or section of the handle which has a nut
fixed in it or to it or separate as the case may be and that either inside or outside
of same which nut screws on to the end of the spindle and being screwed tight
meters and so retains the handle in a firm and secure manner.

We, JAMES SETON PRENTICE, Engineer, 22 Portman Street, Glasgow,
ARCHIBALD BOWIE, Builder, 372 Scotland Street, Glasgow, and MALCOLM
STARK, Junior, 167 St. Vincent Street, Glasgow, Architect 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
This invention which relates to improvements in the method of fixing handles to
locks or doors has for its object to effect the fixing of handles in a simpler and more
efficient manner than hitherto. In carrying out our said invention we provide a
square spindle screwed at both ends on the edges of the square or otherwise.
also provide a half or any section of a handle with square socket in the centre and
recessed or checked at the circumference at the point where the other half or section
of the handle is made to metre. We also provide the other half or section of the
handle which has a nut fixed in it or to it or separate as the case may be and either
inside or outside of same which nut screws on to the end of the spindle and being
screwed tight metre and retains the handles in a firm and secure manner.
In order that our said invention may be properly understood and readily carried
into effect we will now proceed to describe the drawings hereunto annexed.
Figure 1 is a longitudinal section of a brass or other metal handle fixed upon the
spindle in accordance with our said invention.
Figures 2 and 3 are modifications of our invention.
Referring to Figure 1 the handle A has its neck a bored with a square hole to
receive the square spindle B; it being understood that the drawing only shews one
half of the spindle and the one handle, the other handle being a fixture upon

page_text: the other end of the spindle or both handles may be fixed upon the spindle in the
same way, that is to say, in accordance with our said invention.
The head of the handle is provided with a nut C which is formed with an
elongated sleeve r, which is internally screwed so as to be bound upon the screwed
portion of the spindle B; and the said nut is also bound or locked to the top of the
handle by the external screw c'. The arrangement is such that the handle having
been passed on to the spindle, the nut is passed through the centre of the handle's
head and by giving a few turns to the nut with a key or spanner its internal screw
is engaged with the screwed spindle and by continuing to turn the nut the external
screw of the nut is engaged with the head of the handle, and by turning the nut
completely home, the spindle, mut, and head of the handle, are all securely locked
together, the handle being thus firmly fixed as the spindle and the handle become
one fixed body; the handle is thus prevented from shaking or wearing loose.
As a modification of our invention or in cases where the handle is of wood or the
like, we prefer to form the nut C', in the form as shown in Figure 2, the nut being
screwed on to the spindle B, and bound to the head of the handle A.', in the manner
as described with reference to Figure 1, but in this modification we have shown the
head of the nut approximately flush with the head of the handle and fixed in by a
screw driver, spanner or key.
As a further modification of our invention or in cases where the handle is of glass,
china and other like material, and an internal screw cannot be properly formed in
the head of the knob, we form the brass or other metal neck piece D of such
a handle as is shown in Figure 3 with an extension piece d, formed with an external
screw d and we form the nut C² with an internally screwed sleeve c² so that when
the nut is passed through the head of the handle, it first engages with the screwed
spindle B, and then engages with the screw of the extension piece d of the neck
of the handle; the spindle, nut and handle are thus all bound or locked together as
in the other modifications of our said invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1st. In door handles the improved means for attaching the handles to their
spindles substantially as herein before described and shown in the accompanying
drawings.
2nd. In the fixing of door handles to their spindles, the employment of the
locking arrangement C, by means of which the spindle and handle become one fixed
body, substantially as and for the purposes hereinbefore described and shown in
Figure 1 of the accompanying drawings; or any mere modification of the same such
as is illustrated in Figures 2 and 3.
