FREDERICK ALBERT SHARPE Gas and Hot Water Fitter opposite the Corn Hill
Lincoln in the County of Lincolnshire and WILLIAM WOOLLASON Engine Fitter
opposite the Corn Hill Lincoln in the County of Lincolnshire do hereby declare
the nature of the said invention for AN IMPROVED CHIMNEY GEAR FOR RAISING
AND LOWERING THE CHIMNEYS OF PORTABLE ENGINES OR OTHER CHIMNEYS to
be as follows:-
A Tooth Quadrant on the Joint Bolt of the Chimney is worked by a screw Worm
or pinion or a Lever can be used on the same centre, Noa 3 & 4 in the drawing
show a Tooth Quadrant (A) which is used on the Joint Bolt (B) and moved by a
screw (C), or a Lever can be used on the Joint Bolt connected to Chimney Base.
(D) is a Bracket, (E) are the Bosses to carry Screw Spindle (F) and at the end of
Bracket is a Hand Wheel (G) to work the Screw and Quadrant for Raising and
Lowering Chimney, the Quadrant is used for Large and Heavy Chimneys, or any
such means central of that Joint may be used.

We FREDERICK ALBERT SHARPE Gas and Hot Water Fitter and WILLIAM
WOOLLASON Engine Fitter, both opposite the Corn Hill Lincoln Lincolnshire
do hereby declare the nature of our invention for "AN IMPROVED
GEAR FOR RAISING AND LOWERING THE CHIMNEYS OF PORTABLE ENGINES OR
OTHER CHIMNEYS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
Our Invention has for its object to provide means whereby the chimneys or
funnels of portable Engines or other chimneys or funnels can be lowered and raised
with great facility steadiness and safety by one man without any necessity for
getting on to the boiler, the chimney into whatever position it may be brought,
being held securely so that the danger of its being damaged by falling is obviated.
We will describe our Invention with reference to the accompanying drawing
whereon Figure 1 is a plan and Figure 2 an elevation of a chimney or funnel
provided with gear according to our Invention. To the joint bolt a of the chimney
or funnel is fixed a toothed quadrant A (or it may be a complete wheel or other
portion of a wheel). A worm C on a shaft F gears with the said quadrant, the said
shaft being mounted in bearings E fixed to the stationary base of the chimney or
funnel The shaft F can be rotated in the said bearings E by means of a handle or
hand wheel G. It will readily be seen that on rotating the hand wheel G, shaft F,
and worm C, the latter. by gearing with the quadrant A or its equivalent, will
cause the chimney or funnel to be lowered as indicated by dotted lines, and by
rotating the handle in the reverse direction the chimney or funnel will be raised
again.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
For lowering and raising chimneys or funnels a quadrant (or its equivalent) fixed
on or connected with the joint bolt on which the chimney or funnel turns in
combination with means for operating it substantially as hereinbefore described and
illustrated in the accompanying drawings.
