Scaled the 2nd March 1877, and dated the 20th September 1876.
PROVISIONAL SPECIFICATION left by the said Nathaniel Clayton and Joseph
Shuttleworth at the Office of the Commissioners of Patents on the 20th
September 1876.

of Lincoln, Engineers. IMPROVEMENTS IN ROAD LOCOMOTIVES OR TRACTION
ENGINES."
"
Our Invention relates to the steering gear of road locomotives or traction engines,
and consists of a peculiar arrangement and combination of apparatus whereby the
guiding or steering is effected with facility and promptitude.
In carrying out our Invention we employ a toothed sector which is attached by
adjustable hinged joints to the bed of the fore carriage in such a manner that on
radial motion being imparted to such sector the fore carriage shall be turned and
the engine be guided or directed in the required course. This radial motion is
obtained by means of a worm engaging with the sector and which is mounted upon
a horizontal shaft carrying a mitre wheel, to which motion is imparted by another
mitre wheel mounted upon the lower end of an inclined shaft, the upper end of the
latter carrying a steering wheel, by the act of turning which the train of gearing
and consequently the sector is actuated.
The worm, the horizontal shaft, the mitre wheels, and the lower end of the
inclined shaft are carried in suitable bearings on a bracket bolted or otherwise
secured to the under side of the boiler. The bracket also carries a step affording
ready access to the engine for oiling, examination, or any other required purpose.

by the said Nathaniel Clayton and Joseph Shuttleworth in the Great Seal
Patent Office on the 20th March 1877.
NATHANIEL CLAYTON and JOSEPH SHUTTLEWORTH, of Lincoln, in the County
of Lincoln, Engineers. " IMPROVEMENTS IN ROAD LOCOMOTIVES OR TRACTION
ENGINES."
Our said Invention relates to the steering gear of road locomotives or traction
engines, and consists of a peculiar arrangement and combination of apparatus
whereby the guiding or steering is effected with facility and promptitude.
And in order that our said Invention may be fully understood, we shall now
proceed more particularly to describe the same, and for that purpose shall refer to
the several Figures on the annexed Sheet of Drawings, the same letters of reference
indicating corresponding parts in all the Figures.
Figure 1 of the accompanying Drawings represents a side elevation; Figure 2, an
end elevation; and Figure 3, a plan of so much of a road locomotive or traction
engine as is requisite to illustrate our said Invention.
This
We employ a toothed sector A which is attached by adjustable hinged or other
convenient form of joints B to the bed or axle of the fore carriage C in such a
manner that on radial motion being imparted to such sector the fore carriage
shall be turned and the engine be guided or directed in the required course.
radial motion is obtained by means of a worm D engaging with the sector and
which is mounted upon a horizontal shaft E carrying a mitre wheel F, to which
motion is imparted by another mitre wheel F' mounted upon the lower end of an
inclined shaft G, the upper end of the latter carrying a steering wheel H, by
the act of turning which the train of gearing and consequently the sector A is.
actuated.
The worm D, the horizontal shaft E, the mitre wheel F, and the lower end of the
inclined shaft G with its mitre wheel F¹, are carried in suitable bearings on a
bracket I bolted or otherwise secured to the under side of the boiler J. The
bracket I also carries a step K affording ready access to the engine for oiling,
examination, or any other required purpose.
Having now described and particularly ascertained the nature of our said
Invention, and the manner in which the same is or may be used or carried into
effect, we would observe in conclusion that what we consider to be novel and original,
and therefore claim as the Invention secured to us by the herein-before in part
recited Letters Patent is, the employment in the guiding or steering of road
locomotives or traction engines of a toothed sector operated by a worm and other
gearing carried by a bracket attached to the boiler, substantially as herein-before
described and illustrated by the accompanying Drawings.
In witness whereof, I, the said Nathaniel Clayton, on behalf of myself and
the said Joseph Shuttleworth, have to this our Specification set my hand
and seal, this Fifteenth day of March One thousand eight hundred and
seventy-seven.
NATHANIEL CLAYTON. (LS.)
