Improvements in Chimneys or Funnels for the Boilers of Auxiliary
Steam Vessels.
;
I, BENJAMIN LEE GUINNESS of Ballard Coombe Warren, Kingston, in the County
of Surrey, late a Captain in Her Majesty's Regiment of Horse Guards, 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:
This invention has for its object improvements in chimneys or funnels for the
boilers of Auxiliary Steam Yachts, and other vessels, with a view to enable a vertical
portion of the same to be turned down to allow the main boom of a sail to pass over
the same when tacking under sail or steam, and to permit the said chimney or funnel to
be placed at any convenient angle for carrying the smoke clear of the yacht or other
vessel, and to increase the draught.
For this purpose I construct the funnel or chimney with capability of turning,
around a vertical axis, central with the uptake of the boiler, either to the Starboard .
or Port side of the vessel; the main part of the chimney or funnel consists of a short
vertical length, connected, by an elbow, with a horizontal portion fitted with rollers
near its outer end to travel on a suitable path or way; the outer end of this horizontal
portion. is fitted with a swivelling length formed with an elbow so that it can be
turned around a horizontal axis into a vertical or horizontal position, as may be
required..
And in order that my invention may be more clearly understood and readily carried
into effect, I will proceed, aided by the accompanying drawings, to describe one
method in which the same may be carried into effect.

with straps D secured thereto by suitable screws and having hooks at their lower
ends, which arrangement holds the whole in its proper position.
It will thus be seen that a horizontal radius, having its axis in the centre of the
short funnel B, can be traversed by the arm C¹ of the funnel, which arın is supported
by a bracket E provided with wheels or rollers moving upon a radius plate F laid
upon the deck. Or the wheels or rollers may be fitted with india rubber tires, so as
to dispense with the radius plate F. The extent of this horizontal movement is
shown on the drawing, figure 3, in dotted lines. The arm C² of the funnel or chimney
is arranged at right angles to the swivelling part C', and is so constructed as to allow
of a movement of about one half turn, so that it may be placed at any desired angle,
and secured at such point by the set screw G, which works in a slot in the joint. H
for this purpose.
The brackets or lugs I are to allow a handspike or other suitable instrument to be
used to turn this portion of the funnel, and generally work the same. The chimney
or funnel may be constructed of any suitable material, but preferably of copper with
gun metal or brass joints.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The improvements in the construction of chimneys or funnels for the boilers of
auxiliary steam yachts and other vessels, substantially as herein shown and described
and for the purposes stated.
