IMPROVEMENTS IN TRACTION, LOCOMOTIVE, AGRICULTURAL, AND OTHER PORTABLE ENGINES.
Year: 1864

page_text: LETTERS PATENT to Edward Rush Turner and Frederick Turner, of
Ipswich, in the County of Suffolk, for the Invention of "IMPROVEMENTS
IN TRACTION, LOCOMOTIVE, AGRICULTURAL, AND OTHER PORTABLE ENGINES.
PROVISIONAL SPECIFICATION left by the said Edward Rush Turner
and Frederick Turner at the Office of the Commissioners of Patents,
with their Petition, on the 23rd June 1864.
We, EDWARD RUSH TURNER and FREDERICK TURNER, of Ipswich, in the
County of Suffolk, do hereby declare the nature of the Invention for "IMPROVE-
MENTS IN TRACTION, LOCOMOTIVE, AGRICULTURAL, AND OTHER PORTABLE ENGINES,"
to be as follows:-
This Invention has for its object improvements in traction, locomotive,.
agricultural, and other portable engines, and is applicable to those classes of
portable engines which have a locking motion in front. The improvements
consist in extending the upper plating of the steam boiler beyond the fore end
of the boiler. This projection at the end of the boiler has applied to. it the
vertical shaft, by which the fore wheel or wheels are caused to lock. Although
the arrangement for producing the locking motion of the fore wheel or wheels
may be varied, it is preferred that there should be a screw wheel or part of a
screw wheel fixed on the vertical shaft, and that to actuate the shaft a screw

page_text: or worm should gear into this screw wheel. By thus extending the upper
part of the plating of the boiler the fore or locking wheel or wheels may be
of comparatively large diameter, and when two are used they can be caused
to lock under the extended upper part of the end of the boiler.
SPECIFICATION filed in pursuance of the conditions of the Letters Patent,
and of an Order of the Lord Chancellor, by the said Edward Rush
Turner and Frederick Turner in the Great Seal Patent Office on the
13th January 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWARD
RUSH TURNER and FREDERICK TURNER, of Ipswich, in the County of Suffolk,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of June, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Edward Rush Turner and Frederick Turner, Her special licence
that we, the said Edward Rush Turner and Frederick Turner, our executors,
administrators, and assigns, or such others as we, the said Edward Rush
Turner and Frederick Turner, our 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 TRACTION, LOCOMOTIVE, AGRICULTURAL, AND OTHER PORTABLE
ENGINES," upon the condition (amongst others) that we, the said Edward
Rush Turner and Frederick Turner, our executors or administrators, by an
instrument in writing under our or their hands and seals, or under the hand
and seal of one of us or them, 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 Office
on or before the Seventeenth day of January One thousand eight hundred
and sixty-five.
NOW KNOW YE, that we, the said Edward Rush Turner and Frederick
Turner, do hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described and ascer
tained in and by the following statement thereof, that is to say:-

page_text: This Invention has for its object improvements in traction, locomotive,
agricultural, and other portable engines, and is applicable to those classes of
portable engines which have a locking motion in front. The improvements
consist in extending the upper plating of the steam boiler beyond the fore end
of the boiler. This projection at the end of the boiler has applied to it the
vertical shaft, by which the fore wheel or wheels are caused to lock. Although
the arrangement for producing the locking motion of the fore wheel or wheels
may be varied, it is preferred that there should be a screw wheel or part of a
screw wheel fixed on the vertical shaft, and that to actuate the shaft a screw
or worm should gear into this wheel. By thus extending the upper part of
the plating of the boiler the fore or locking wheel or wheels may be of com-
paratively large diameter, and when two are used they can be caused to lock
under the extended upper part of the end of the boiler.
Having thus stated the nature of our said Invention, we will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews a side elevation, and Figure 2 an end view of a boiler
constructed according to our Invention suitable for a traction, locomotive,
agricultural, or other portable engine; Figure 3 shows a modification of the
boiler by raising the smoke box.
a is the fire-box end of the boiler; b, the body of the engine; c, the smoke-
box end of the boiler, beyond which the upper plating of the boiler is carried,
as is shown at d, d. There is an opening in the lower part of the end plate of
the smoke box, which is covered by a suitable door. The plating d, d, forms
an extension or continuation of the front of the boiler or smoke box, forming
part of a boiler, which extension may be wholly closed in at the outer end and
on the under side or not, as may be desired. In the Drawings the extension
d, d, is shown to be only partially enclosed by a horizontal plating e, e, in
order to receive and have fixed thereto the tubular bearing f, through and in
which the upper part of the vertical axis of the locking motion works. The
locking motion is preferred to be similar to what has been before used, and
consists of a vertical axis, to the lower end of which the fore axle (on the ends
of which are the two fore wheels) is fixed, and motion is given by a worm or
screw to a part or sector of a screw or worm wheel fixed on the vertical
axis.
By thus extending the fore end of the boiler
whilst the locking motion of the fore wheels is
below the extension of the plating of the boiler.
framing is dispensed with,
most conveniently applied
It will be evident to an

page_text: engineer that the form of the boiler may be varied, and yet have its plating
extended according to our Invention, so as to have the fore wheels or wheel
below and to lock under such extension, and it is the extending of the plating
of a steam boiler suitable for a traction, locomotive, agricultural, or other
portable engine which constitutes the peculiarity of our Invention.
In witness whereof, we, the said Edward Rush Turner and Frederick
Turner, have hereunto set our hands and seals, this Tenth day of
January, in the year of our Lord One thousand eight hundred and
sixty-five.
