page_text: FREDERICK ALBERT SHARPE Gas and Hot Water Fitter opposite the Corn Hill
Lincoln 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:--
This Invention is applied to the Chimney of a Portable Engine for raising and
lowering it by means of a screw with a hand wheel attached passed through a nut
turning in a bracket fixed to the bottom of the Chimney and through a similar nut
with a clear hole, in another bracket on the other side of the Chimney joint.
There is a long stay inside the Chimney to strengthen it, the stay is riveted on on
the top of Chimney on the back side inside of the Chimney and crosses it and is.
bolted at the bottom of the bracket.
It necessarily follows that this invention dispences of labour as one man can
raise or lower the Chimney, it prevents accidents arising from the men having to
get on the top of the boiler, preserves the engine from being damaged from the
same cause, it is steady and safe in using and will hold the Chimney fast when
travelling, and prevent it from being knocked into holes which has caused many
fires in stack yards.

GENERAL REMARKS, NAMELY LETTERS ON THE DRAWING.
For raising and lowering Chimneys there are (2) malleable iron brackets, (A) is
on one bracket on Chimney and (B) is on the other bracket on the base. There is
a screwed centre nut (C) in the top bracket (A) it is passed through two eyes in
the bracket bosses (D) on the Chimney. The centre nut (E) on the base bracket (B)
has a clear hole to allow the screw (F) to pass through easily. There is a loose
collar (H) pinned on the screw spindle (F) on the top side of the bracket. The
bottom collar (I) is welded on the screwed spindle. The screw works round in a
free neck of the spindle At the bottom there is a hand wheel (J) underneath for
working the screw spindle for raising and lowering the Chimney. There is a long
stay inside the Chimney to strengthen the same, the stay is reveted on the top on
the back side, inside of Chimney which crosses the Chimney and bolted at the
botton of Chimney bracket.

page_text: We FREDERICK ALBERT SHARPE Gas & Hot Water Fitter and WILLIAM
WOOLLASON Engine Fitter both opposite the Corn Hill, Lincoln Lincolnshire do
hereby declare the nature of this invention for "AN IMPROVED CHIMNEY 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:―
The object of this Invention is 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.
According to our Invention we effect the lowering and raising of the chimney
by means of a screwed spindle or rod passed through nuts or carriers which are so
mounted that they swivel or adjust themselves to the altered position of the
spindle due to the rotation thereof in lowering or raising the chimney or funnel.
We will describe ways in which our Invention may be conveniently performed
reference being had to the accompanying drawings, whereon Figures 1 and 2 are
elevations at right angles to each other of a chimney or funnel provided with
means for raising and lowering the same according to our Invention. Figures 3
and 4 are like views shewing a slightly modified form of the arrangement and
Figures 5 and 6 are like views shewing a further slight modification all as herein-
after described but in all the arrangements illustrated, the essential features are
the same.
The figures 24 44 and 64 shew the chimney or funnel of each arrange-
ment in its lowered position.
Referring to Figures 1. 2 and 2ª a bracket A is fixed to the lower portion of
the movable part of the chimney or funnel and another bracket B is secured on the
fixed base part of the chimney or funnel A screw nut C is formed with trunnions
by which it is capable of swivelling in eyes or bearings & formed for it in bosses
on the bracket A and a plain or unscrewed nut E is similarly mounted in the
lower bracket B. A screwed spindle F is passed through the plain hole in the
nut E and also through the screwed hole of the nut C so that it engages with the
screw thereof. A loose collar H is pinned or otherwise secured on to the spindle F
at the upper side of the nut E and a bottom collar I is welded or otherwise fixed
on the said spindle F below the said nut so that the said spindle F is longitudinally
secured in the said nut but can be rotated therein-The said spindle is provided
with a hand wheel or handle J for rotating it. On a motion of rotation being
given to the said hand wheel or handle J and consequently to the spindle F the
screw on the said spindle by its engagement with the screw nut C. causes the said
nut to travel along the said screw whereby the nuts C and E are forced apart and
the chimney or funnel is lowered, the nuts turning upon their trunnions to
accommodate themselves to the altered position of the parts. Figures 3. 4 and 4ª
shew the nuts E and C. arranged to swivel on pins passed through single luge
"

page_text: formed on the brackets but the parts are substantially the same as in Figures 1
and 2 and are marked with the same letters of reference. The arrangement
Figures 5. 6 and 6ª are substantially the same as in Figures 1 and 2 and are also
marked with the same letters of reference but in place of using a plain nut and a
screwed nut, both the nuts E and C. are screwed and the spindle F has a right hand
thread on the part engaging with the one nut, and a left hand thread on the part
engaging with the other nut, and is operated by means of a handle or hand
wheel J fixed thereto between the brackets A and B.
The chimney or funnel is preferably strengthened as shewn in Figure 7 by an
internal diagonal stay k rivetted or otherwise fastened at top to the upper end of
the chimney or funnel, and extending downwards transversely across the chimney
or funnel to the lower part of the opposite side and there bolted or otherwise
fastened to the chimney or funnel preferably by bolts passing also through the
bracket A.
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
1st For lowering and raising chimneys or funnels the employment of a screwed
spindle or rod passing through swivelling or adjustable nuts or carriers on the
moving and stationary portions respectively substantially as hereinbefore described
and illustrated by the accompanying drawings.
2nd The several arrangements and combination of parts constituting the lowering
and raising gear for Chimneys or funnels substantially as hereinbefore described
and illustrated in the several figures of the accompanying drawings.
3rd Providing Chimneys or funnels with an internal diagonally disposed
strengthening stay substantially as hereinbefore described.
Dated this 31st day of January 1885.
