PROVISIONAL SPECIFICATION.
Improvements in and connected with Bolts and Nuts.
ALBERT FREDERICK SAUL, 49 Swansea Street Preston, Joiner, and JOHN
SOUTHWORTH 1 Derby Terrace Watery Lane Preston Lancashire Overlooker, both
in the County of Lancaster do hereby declare the nature of this invention to be as
follows:-
A bolt screwed on both ends, on one end of which, is a loose square nut, and on
the other end, is a loose bevil toothed wheel, which is worked by a bit with bevil
teeth on the bottom, applied vertically above it.

Improvements in and connected with Bolts and Nuts.
We, ALBERT FREDERICK SAUL, of 49, Swansea Street, Preston, Joiner, and JOHN
SOUTHWORTH, of 1, Derby Terrace, Watery Lane, Preston, Overlooker, 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:-
The bolts and nuts to which our invention more particularly refers are of the
kind employed for screwing up or drawing together the different lengths or sections
of wooden hand rails. As heretofore employed such bolts have been screw-threaded
near each end the screw-threaded parts each carrying a nut one of them being of
the ordinary square kind and the other round or cylindrical with longitudinal
grooves or furrows to which a suitably pointed chisel and a hammer are applied to
effect the rut's rotation.
According to our invention we employ a similar bolt and at one end a square nut
of the usual kind but in lieu of the ordinary grooved cylindrical nut we employ a
nut in the form of a toothed bevel wheel which is rotated on its bolt by means of
an implement in the form of a bit having bevel teeth on its outer extremity which
gear into the bevel wheel nut the bit being rotated preferably by means of a brace
of the kind usually employed by joiners the bevel wheel nut within its recess in the
hand-rail being thus capable of being readily screwed up or unscrewed as required.
In order that our invention may be the better understood reference is had to the
accompanying drawings in which Fig. 1 is a longitudinal sectional view and Fig. 2
a cross sectional view of a hand rail to which our improved bolt and nut are applied

page_text: In the said figures A A represent two adjoining sections of a handrail; b is the
bolt screw-threaded near each end; c the ordinary square nut, and d our improved
nut in the form of a toothed bevel wheel. e is a washer of the usnal kind. fis the
bit having bevel teeth upon its outer extremity. The other end f' is preferably
squared so as to fit an ordinary joiner's brace.
Fig. 3 is a sectional view shewing an opening 9 in the underside of the bandrail
into which the bit f is introduced-the side g¹ (see also Fig. 1) of the opening g
forming a resistance or thrust bearing to receive the pressure of the bit whilst
engaged in rotating the bevel wheel nut d.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is :-
With screw bolts of the kind specified the use of a screw-threaded unt in the
form of a toothed bevel wheel and means for rotating the said nut substantially as
herein described and shewn in the drawings.
Dated this 23rd day of July 1897.
