Year: 1864

page_text: LETTERS PATENT to Daniel Crowe, of Gaywood, Lynn, in the County of
Norfolk, Engineer and Implement Manufacturer, for the Invention of
"IMPROVEMENTS IN APPLYING POWER TO AND IN ACTUATING COMBINED PORT-
ABLE THRASHING AND DRESSING MACHINES."
Sealed the 28th October 1864, and dated the 23rd June 1864.
PROVISIONAL SPECIFICATION left by the said Daniel Crowe at the
Office of the Commissioners of Patents, with his Petition, on the 23rd
June 1864.
I, DANIEL CROWE, of Gaywood, Lynn, in the County of Norfolk, Engineer
and Implement Manufacturer, do hereby declare the nature of the Invention
for "IMPROVEMENTS IN APPLYING POWER TO AND IN ACTUATING COMBINED PORTABLE
THRASHING AND DRESSING MACHINES," to be as follows:-
This Invention has for its object improvements in applying power to and in
actuating combined portable thrashing and dressing machines.
Heretofore, when using steam power to give motion to the parts of a
combined portable thrashing and dressing machine, a separate portable steam

page_text: engine has been generally employed. Now the present Invention consists in
combining a steam engine with a combined portable thrashing and dressing
machine, in order that the machine and steam power may be combined in
one carriage. When the carriage is to be locomotive the steam engine is
geared with and is thus caused to give motion to the axis of some of the
wheels of the carriage, in like manner to what is practised in giving motion
to traction or other locomotive carriages suitable for running on common
roads, or the carriage may be constructed to admit of its being drawn by
horses.
The machinery of the portable combined thrashing and dressing machine
is constructed as heretofore, but the moving parts thereof receive motion from
the main shaft of the steam engine mounted on the same carriage as the
thrashing and dressing machinery. It is preferred that there should be a
drum or drums on the main shaft of the steam engine, and that the power of
the engine should be transmitted by a strap or straps to the moving parts
of the thrashing and dressing machinery, but this may be varied and other
arrangements of gearing employed between the steam engine and such
machinery.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Daniel Crowe in the Great Seal Patent Office on the g
14th December 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DANIEL
CROWE, of Gaywood, Lynn, in the County of Norfolk, Engineer and Imple-
ment Manufacturer, 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 me, the
said Daniel Crowe, Her special licence that I, the said Daniel Crowe, my
executors, administrators, and assigns, or such others as 1, the said Daniel a
Crowe, 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 APPLYING POWER

page_text: TO AND IN ACTUATING COMBINED PORTABLE THRASHING AND DRESSING MACHINES,"
upon the condition (amongst others) that I, the said Daniel Crowe, 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 Office within
six calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Daniel Crowe, 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:-
This Invention has for its object improvements in applying power to and in
actuating combined portable thrashing and dressing machines.
Heretofore, when using steam power to give motion to the parts of a
combined portable thrashing and dressing machine a separate portable steam
engine has been generally employed. Now the present Invention consists in
combining a steam engine with a combined portable thrashing and dressing
machine, in order that the machine and steam power may be combined in
one carriage. When the carriage is to be locomotive the steam engine is
geared with and is thus caused to give motion to the axis of some of the
wheels of the carriage, in like manner to what is practised in giving motion
to traction or other locomotive carriages suitable for running on common
roads, or the carriage may be constructed to admit of its being drawn by
horses.
The machinery of the portable combined thrashing and dressing machine
is constructed as heretofore, but the moving parts thereof receive motion from
the main shaft of the steam engine mounted on the same carriage as the
thrashing and dressing machinery. It is preferred that there should be a
drum or drums on the main shaft of the steam engine and that the power of
the engine should be transmitted by a strap or straps to the moving parts of
the thrashing and dressing machinery, but this may be varied and other
arrangements of gearing employed between the steam engine and such
machinery.
Having thus stated the nature of my Invention, I will proceed to describe
more fully the manner of performing the same.

page_text: Figure 1 shows a side view, and Figure 2 an end view of a portable
thrashing and dressing machine combined with a steam engine constructed in
the manner I prefer for carrying out my Invention.
In these Drawings I have not thought it necessary to shew the working
parts of the thrashing and dressing machine, nor all the working parts of the
steam engine, but only so much of these as will enable a workman readily to
combine a steam engine with a portable thrashing and dressing machine. The
engine is, as is shown in the Drawings, placed at one end of the thrashing
and dressing machine, and the boiler of the engine is made to extend beneath
it, so that the combined machine is of little greater length than the ordinary
thrashing and dressing machine. The back end of the boiler is carried from
the framing of the thrashing machine by the bent iron support a, the front
end of the boiler is supported by the bent axle b, upon which the hinder pair
of wheels c turn, and also by the side plates d, which plates are connected to
the sides of the framing of the thrashing and dressing machine, and they both
support the front of the boiler and also the platform upon which the man
working the engine stands. The boiler I prefer to construct in the manner
shown by the Drawings. The fire-place is formed in a vertical part e of the
boiler, and the products of combustion pass from the fire over the bridge f
and enter tubes g in the portion of the boiler that runs beneath the thrashing
and dressing machine. At the back end of this part of the boiler the tubes
open into a chamber, from which the products of combustion pass by larger
tubes h to the inclined passage i, that leads through the upright portion of
the boiler, and so to the chimney k. The cylinder and working parts of the
engine are, as is shown in the end view, Figure 2, placed at one side of the
upright portion of the boiler and the crank shaft is placed above it. From
this shaft motion is transmitted to the working parts of the thrashing and
dressing machine by a strap 7 passing around the driving wheel m; this strap
gives motion to the pulley n on one end of the crank shaft that works the
riddles; on the opposite end of this shaft is a pulley which by a strap transmits
motion to the axis of the beaters, and from these axes motion is transmitted
to the various parts of the thrashing and dressing machine, as is usual in
machines of this description. From the crank shaft of the engine motion can
also be transmitted to the pair of wheels c, upon which the hinder end of the
machine is supported; each of these wheels has a toothed wheel formed
within it into which a pinion o gears; on the axis of each pinion is a friction

page_text: wheel, which by other friction wheels p can be caused to gear with a friction
wheel on the crank shaft. The friction wheels p can be moved in and out
of gear by the lever handles r, as is shown. By this means by putting the
friction wheels in gear the machine may be driven from place to place, and by
raising the lever handles the driving wheels may be thrown out of gear with
the engine.
In witness whereof, I, the said Daniel Crowe, have hereunto set my
hand and seal, this Twelfth day of December, in the year of our Lord
One thousand eight hundred and sixty-four.
DANIEL CROWE. (L.S.)
