I GEORGE GIBSON BUSSEY of Museum Works, Rye Lane, Peckham in the
County of Surrey do hereby declare the nature of my Invention for IMPROVEMENTS
IN LOCK SPINDLES AND THE METHOD OF SECURING HANDLES THERETO to be as
follows:
The object of one part of this invention is to reduce the labour of making a
spindle exactly fit the square hole of the lock follower, which (in its normal state)
is too large. For this purpose I form longitudinal grooves along each side of the
square of the spindle, so that, when a file is applied to reduce the size, it has only
to cut the projecting edges and not the flat of the spindle. Labour is thus not
only saved, but a more effectual fit secured than when the whole surface has to be
filed away.
A further and more important object of this invention is simply but effectually
to attach the handles to the spindle. To accomplish this I reduce about one inch
of one or both ends of the spindle to a round stem about half its original
substance.
On this stem I form a screw thread on which has to work a peculiarly formed
nut with shouldered head or boss. The neck of my knob shaped handles are fitted
with the usual square socket to receive a proportion of the square of the spindle.
The remainder of the handle is bored through with a hole which may be round,
square, parallel or conical.
The aforesaid screw nut works in this hole and engages with the screw of the
spindle but is prevented from working through the handle by the shoulder formed
thereon. It thus fixes in a most simple yet efficacious manner the handle to the
spindle, which, while it never in use works loose, can yet be detached with the
greatest ease by unscrewing the shouldered nut.

page_text: Improvements in Lock Spindles and the Method of Securing
Handles thereto.
I, GEORGE GIBSON BUSSEY, of Museum Works, Rye Lane, Peckham, in the
County of Surrey, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of one part of this invention is to reduce the labour of making a
spindle exactly fit the square hole of the lock follower, which (in its normal state)
is too large. For this purpose I form longitudinal grooves along each side of the
square of the spindle, so that, when a file is applied to reduce the size, it has only
to cut the projecting edges and not the Hat of the spindle. Labour is thus not
only saved, but a more effectual fit secured than when the whole surface has to be
filed away.
A further and more important object of this invention is, simply, but effectually,
to attach the handles to the spindle. To accomplish this I reduce about one inch
of one or both ends of the spindle to a round stem about half its original
substance. On this stem I form a screw thread to receive a specially formed nut
with shouldered head or boss. The necks of my knob shaped handles are fitted
with the usual square socket to receive a proportion of the square of 'the spindle.
The remainder of the handle is bored through with a hole which may be round,
square, parallel or conical.
The aforesaid screw nut works in this hole and engages with the screw of the
spindle, but is prevented from working through the handle by the shoulder formed
thereon. It thus fixes in a simple and efficacious manner the handle to the spindle,
which, while it never in use works loose, can yet be detached with the greatest
ease by unscrewing the shouldered nut.
And in order that my said invention, may be particularly described and
'ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parta
Fig. 1 is a section of the spindle c. Fig. 2 is an end view of the knob or
handle d. Fig. 3 is a section of the handle on the line a b of Fig. 2. Fig. 4 is a
side view of the nut f, and Fig. 5 is a section of the nut f.
The spindle is formed with a longitudinal groove c¹ on each of its four sides,
which form reduces the labour in making the spindle fit the square hole in the lock
follower. The spindle is reduced, at one or both ends, as shown at g (Fig. 3) and
has a screw thread formed upon such reduced portion or portions. The form of
the nut will be understood on reference to the drawings. The head is formed
with one, two, or more saw-cuts h, in order that it may be turned with an ordinary
screw-driver. These saw-cuts are preferably made ornamental, as shown at h
(Figs. 2, 3, 4 and 5). The mount e is fitted with a square hole in the ordinary
manner.
A suitable hole having been made through the knob d, and the mount e attached
thereto, the spindle c is inserted therein: the nut f being then inserted in the outer

page_text: end of the knob, the female screw cut therein engages the screw g at the end of
the spindle: the nut is then turned until the handle is secured, as shewn in Fig. 3.
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 method of securing handles to lock spindles by means of the nut f,
secured to the screw 9, formed upon the spindle c, severally operating substantially
as herein before described and shewn on the drawings.
2. The general arrangement, construction and combination of the several and
respective parts, together forming my improvements in lock spindles and the
method of securing handles thereto, substantially as herein before described and
shewn on the drawings.
