PROVISIONAL SPECIFICATION.
An Improved Combined Portable Boiler and Centrifugal Pump
and Engine.
We, TANGYES LIMITED, of Cornwall Works, Birmingham in the County of
Warwick, Engineers, and THOMAS JEFFERISS of Holyhead Road, Handsworth, in the
County of Stafford, Engineer, do hereby declare the nature of this Invention to be as
follows:-
This Invention has for its object to provide a combined portable boiler and
Centrifugal pump and Engine, wherein balancing of weights and freedom from
vibration are obtained, and both pump and Engine are kept free from the dust due
to firing the furnace of the Boiler and the fire-door of the said furnace can be placed
in the front instead of at one side as is the usual custom and morcover the pump and
the Engine can be easily removed when required.
According to this Invention a base or frame is connected to the back of the fire-
box extending from side to side between the pairs of wheels and it is further
supported from the barrel of the boiler; this base may be made preferably of
wrought iron, of rigid but light construction; on this base is secured the engine bed,
preferably of cast iron; at one side is affixed the steam engine and on the other
projecting side of the same base, the Centrifugal pump is secured, the spindle of
pump being connected by means of a coupling to the crank shaft of the Engine.
The Pump is so arranged that it can be turned in several directions to meet the
varied requirements of suction and delivery pipes, and when the pump is not required
the pump coupling can be disconnected from the crank-shaft and the engine be used
for other purposes.
A Fly-wheel on the outer side of the shaft is conveniently placed to give off the
power by means of belting or the like.

WO TANGYES LIMITED of Cornwall Works Birmingham in the County of Warwick
Engineers and THOMAS JEFFERISS of Holyhead Road Handsworth in the County
of Stafford Engineer 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 to provide a combined portable boiler and
Centrifugal Pumping Engine wherein balancing of weights and freedom from
vibration are obtained and both pump and engine are kept free from the dust due to
firing the furnace of the Boiler and the fire door of the said furnace can be placed in
the front instead of at one side as is the usual custom and moreover the pump and
the engine can be easily removed when required. Figure 1 of the accompanying
drawing is a side elevation. Figure 2 an end view and Figure 3 a plan of a combined
portable boiler and centrifugal pumping engine according to this invention.
A base
or frame A is connected to the back of the fire-box, B, the said base or frame
extending from side to side between the pairs of wheels C. CO2 and it is further
supported from the barrel D of the boiler by the plate d.
This base or frame A is preferably made of wrought iron of rigid but light con-
struction and on it is secured the Engine bed E preferably made of cast iron. This
bed E is secured to the wrought iron frame A one end carrying the engine F and
the other end the pump G. The crank shaft fand pump spindle g begin connected
by a coupling and passing close under body of the boiler-The pump G is so arranged
that it can be turned and fixed in any required direction to meet the varied require-
ments of its suction and delivery pipes and when the pump is not required the pump
coupling can be disconnected from the crank shaft and the engine F be used for
other purposes. I is a fly wheel on the outer side of the shaft conveniently placed to
give off the power by means of belting or the like.
h
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is.
The improved combined portable boiler and centrifugal pump and engine having
its parts arranged and combined as a whole substantially as hereinbefore described
and illustrated in the accompanying drawings.
Dated this 23rd day of December 1887.
