page_text: LETTERS PATENT to James Shand, of the Firm of Shand, Mason, and
Company, of Upper Ground Street, Blackfriars Road, in the County of
Surrey, for the Invention of "IMPROVEMENTS IN STEAM FIRE ENGINES AND

PROVISIONAL SPECIFICATION left by the said James Shand at the
Office of the Commissioners of Patents, with his Petition, on the 16th
March 1867.
I, JAMES SHAND, of the Firm of Shand, Mason, and Company, of Upper
Ground Street, Blackfriars Road, in the County of Surrey, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN STEAM FIRE ENGINES
AND BOILERS, SUCH IMPROVEMENTS BEING APPLICABLE TO OTHER PURPOSES," to be as
follows:-
The first part of my improvements relates to the construction of vertical
tubular steam boilers of steam fire engines, boilers of this improved construction
being also applicable to other purposes, the object of this part of my Invention
being the reduction of the cost of construction of vertical tubular steam boilers
having submerged smoke boxes, and also to render the upper ends of the tubes
more easy of access thereto for cleaning and repairs. For this purpose, in
constructing a vertical tubular steam boiler with submerged smoke box, instead
of connecting the part of the boiler above the smoke box by an annular or
central space to the part below the smoke box, I arrange two or more spaces

page_text: (preferring three) to form such connection, and I enclose the smoke box by a
metal casing which is easily removed, so as to obtain ready access to the upper
ends of the boiler tubes when required. The part of the boiler above the
smoke box is attached to the parts forming the two or more connecting spaces
by a flange with bolts and nuts for each space. To the lower tube plate and
directly under each connecting space a large tube with closed end may be fixed,
and if required may communicate with the smoke box by a small tube, the
object of these large tubes being to reduce the quantity of water and increase
the heating surface of the boiler.
The second part of my improvements relates to the construction of the
pumps and valves of steam fire engines, such improvements being applicable
to pumps employed for other purposes. This part of my Invention applies
to the construction of pumps with one or more cylinders, the pistons or buckets
of which are fitted with valves, the object being to render the valves easy of
access without disturbing the suction-connections, and this part of my improve-
ments is applicable to pumps whether placed vertically, horizontally, or at an
angle. For this purpose I-construct the suction valve in the same manner as
the piston or bucket, and fit it accurately in the end of the working part of
the pump cylinder with a cup leather or other suitable packing; the suction
valve is attached to or forms part of a flanged cover which closes the end
of the pump cylinder, leaving space between the suction valve and said
flanged cover to form the suction connections, so that on removing the flanged
cover the suction valve is removed with it, and access is obtained to the piston
or bucket.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said James Shand in the Great Seal Patent Office on the 14th
September 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
SHAND, of the Firm of Shand, Mason, and Company, of Upper Ground
Street, Blackfriars Road, in the County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of March, in the year of our
Lord One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said James Shand, Her special licence that I, the said James Shand, my
executors, administrators, and assigns, or such others as I, the said James Shand,

page_text: my executors, administrators, and assigns, should at any time agree with, and
no others, from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS IN STEAM FIRE ENGINES AND
BOILERS, SUCH IMPROVEMENTS BEING APPLICABLE TO OTHER PURPOSES,"
upon the
condition (amongst others) that I, the said James Shand, my executors or
administrators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Oflice, within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Shand, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-

struction being also applicable to other purposes, the object of this part of my

The second part of my improvements relates to the construction of the
pumps and valves of steam fire engines, such improvements being applicable
to pumps employed for other purposes. This part of my Invention applies to

page_text: the construction of pumps with one or more cylinders, the pistons or buckets
of which are fitted with valves, the object being to render the valves easy of
access without disturbing the suction connections, and this part of my improve-
ments is applicable to pumps whether placed vertically, horizontally, or at an
angle. For this purpose I construct the suction valve in the same manner as
the piston or bucket, and fit it accurately in the end of the working part of
the pump cylinder with a cup leather or other suitable packing. The suction
valve is attached to or forms part of a flanged cover which closes the end of

DESCRIPTION OF THE DRAWING.
The Drawing shows two views of a boiler arranged according to my
Invention.
Figure 1 is a vertical section, and Figure 2 a sectional plan through the
line G, II, Figure 1. The water spaces B connect the part M of the boiler
below the smoke box A with the part L of the boiler above the smoke box by
means of flanges C with bolts and nuts; the metal casing F encloses the
smoke box, and is easily removed to give access to the ends of the tubes; the
large tubes D with closed upper ends are attached to the lower tube plate N
directly under each connecting water space B to reduce the quantity of water
and increase the heating surface, and the tubes D may be connected with the
smoke box A by the short tubes O so as to cause a circulation of the products
of combustion from the fire-box E to the smoke box A.
Figure 3 shows an end view, and Figure 4 a side view of a steam fire
engine. arranged according to the second part of my Invention, part of the
pump cylinder P being shown in section; J is the suction valve, made in the
same manner as the pump bucket, and attached to the flanged cover K of the
pump cylinder, leaving a space Q to form the suction connections R and S.
It will be seen that upon removing the cover K the suction valve J is removed
at the same time.
Having thus described the nature of my Invention, and the manner of
performing or carrying the same into practice, I would have it understood
that I do not confine myself to the exact details herein described, as the same
may be varied without departing from the true character of my Invention,
but what I claim is,

page_text: First, the improved construction of vertical tubular steam boilers for steam
fire engines and other purposes, as herein described in reference to Figures 1
and 2 of the Drawing hereunto annexed.
And, secondly, I claim the arrangement and construction of the pump,
cylinders, and suction valves of steam fire and other engines, as herein described
in reference to Figures 3 and 4 of the Drawing hereunto annexed.
In witness whereof, I, the said James Shand, have hereunto set my hand
and seal, this do Seventh day of September, in the year of our Lord
One thousand eight hundred and sixty-seven.
JAMES SHAND. (L.S.)
