Year: 1872

page_text: LETTERS PATENT to Adam Carlisle Bamlett, of Thirsk, in the County
of York, Agricultural Engincer, for the Invention of "IMPROVEMENTS
IN REAPING AND MOWING MACHINES."
Sealed the 12th April 1873, and dated the 15th October 1872.
FROVISIONAL SPECIFICATION left by the said Adam Carlisle Bamlett
at the Office of the Commissioners of Patents, with his Petition,
on the 15th October 1872.
I, ADAM CARLISLE BAMLETT, of Thirsk, in the County of York,
Agricultural Engineer, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN REAPING AND MOWING MACHINES," to be as
follows:-
This Invention relates to improvements in combined reaping &
mowing machines, the object of the first part of the Invention being to
increase the width of the reaping cut in such machines in a more simple
manner than has hitherto been accomplished, & consists mainly in
making the knife bar long enough to hold one more cutting "section"
than is required for mowing, & in forming with the reaping shoe an
additional finger.
When desired to be used for reaping the mowing shoe is removed
from the finger bar and the reaping shoe bolted on, and the additional

page_text: **
'section" is rivetted on to the knife bar, so that the width of cut in
reaping is increased by one finger and section, which will be found of
great advantage.
The Invention further consists in constructing the framework of
reaping and mowing machines in an improved manner with a novel
combination of what is known as the sun-and-planet gearing, the
framework being made in two parts; on one part is formed an internal
spur wheel, and the other part is made of the same diameter. The parts
are bolted together so as to form an oil-tight case having a long boss
on each side of it through which the main axle works. On the axle
the usual travelling wheels are mounted, provision being made in the
usual manner for the finger bar, draft pole, & the other appliances
usually connected with reaping and mowing machines.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Adam Carlisle Bamlett in the Great Seal Patent
Offico on the 15th April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ADAM
CARLISLE BAMLETT, of Thirsk, in the County of York, Agricultural
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of October, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Adam Carlisle Bamlett, Her special licence
that I, the said Adam Carlisle Bamlett, my executors, administrators,
and assigns, or such others as I, the said Adam Carlisle Bamlett, my
exccutors, 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 REAPING AND MOWING MACHINES," upon the condition (amongst others)
that the said Adam Carlisle Bamlett, 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

page_text: 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 Adam Carlisle Bamlett, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement in writing, and on reference being had to the
accompanying Drawings:-
This Invention relates to improvements in combined reaping and
mowing machines, the object of the first part of the Invention boing to
increase the width of the reaping cut in such machines in a more simple
manner than has hitherto been accomplished, and consists mainly in
making the knife bar long enough to hold one more cutting "section
than is required for mowing, and in forming with the reaping shoc an
additional finger.
"
When desired to be used for reaping the mowing shoe is removed
from the finger bar and the reaping shoe bolted on, and the additional
"section" is rivetted on to the knife bar, so that the width of cut in
reaping is increased by one finger and section, which will be found of
great advantage.
The Invention further consists in constructing the framework of
reaping and mowing machines in an improved manner with a novel
combination of what is known as the "sun-and-planet" gearing, the
framework being made in two parts; on one part is formed an internal
spur wheel, and the other part is made of the same diameter. The parts
are bolted together so as to form an oil-tight case having a long boss
on each side of it through which the main axle works. On the axle
the usual travelling wheels are mounted, provision being made in the
usual manner for the finger bar, draft pole, and the other appliances
usually connected with reaping and mowing machines.
Such being the nature and object of my said Invention for "Improve-
ments in Reaping and Mowing Machines," I will now proceed to
describe more in detail the manner in which the same is to be or may
be performed or carried into practical effect, and in order that the same
may be distinctly understood I have annexed hereunto one Sheet of
Drawings illustrative thereof, and have marked the same with figures of

page_text: reference corresponding with those in the following explanation thereof,
that is to say —
"
On the accompanying Drawings Figures 1 to 4 illustrate the first
part of the Invention. In carrying the same into practical effect I
make the knife bar 1 (Figure 1) sufficiently long to hold one more i
cutting "section" 2 than is required for mowing, and I form or construct
with the reaping shoe 3 (Figure 2) a finger 4.
When desired to reap the mowing shoe (in which no addition or
alteration is made, and which is therefore not illustrated on the accom-
panying Drawings) is removed from the finger bar 5 (Figure 3), to
which the reaping shoe.3 is then bolted, as dotted through holes 6 in
both, thus increasing the length of the finger bar in reaping by the
additional finger on the said shoe.
The additional "section" 2 is also rivetted on to the knife bar 1, as
dotted, through holes 7 therein, whereby the width of the reaping cut 1
in the said combined reaping and mowing machine is increased as
compared with that of the mowing cut by one finger and cutting section,
which it will be readily understood is of great practical advantage.
Figure 1 represents a portion of the knife bar as used for mowing,
with the additional section dotted in position for reaping; Figure 32
represents a portion of the finger bar as used for mowing, dotted in
position in Figure 2 as used for reaping; and Figures 2 and 4 represent
the reaping shoe, showing the addition of the finger & thereto, the former
showing also the finger bar in position for reaping.
The second part of the Invention is illustrated in Figure 5. A sectional
plan 8 represents that part of the framework of the said combined
machines wherein the improvements consist. It is made in two
parts 9, 10, which are bolted together round continuous flanges 11, or
through equivalent lugs placed at intervals round the circumference, in
such a manner as to form an oil-tight case. 12 represents a rim of
internal teeth formed on the interior of the part 10; and 13 represents
the inner circumference of the other part 9, which is of the same diameter
as the part 10. 14, 14*, represent the "sun-and-planet" gearing, which
is enclosed by the said case and actuates the bevil gearing 15, 15*, in
a way well known, and by means of the latter actuates the crank 16 of
the knife bar. The wheel 14* is counterbalanced by the weight 22.

page_text: On either side of the case is a long boss 17 through which works the
main axle 18 on which the travelling wheels are mounted at 19.
20 represents a clutch fast on the axle 18, which by means of another
clutch 21 (when geared therewith) made fast to the planet wheel 14*
drives the gearing 14, 14*. The sun wheel 14 is made fast to the driving
wheel 15 and receives the motion from the wheel 14* and imparts it to
the wheel 15*.
Having now described the nature and object of my said Invention
for "Improvements in Reaping and Mowing Machines," together with
the manner in which the same is to be or may be performed or
carried into practical effect, I would remark in conclusion that I claim
as my Invention,―
Firstly. The improved and peculiar means of increasing the width of
the reaping cut as compared with that of the mowing cut in combined
reaping and mowing machines.
And, secondly. The improved and peculiar construction and arrange-
ment of the framework (forming an oil-tight casing for the gearing
actuating the knife bar) and the application in combination therewith of
the "sun and planet" gearing for actuating the same, all substantially
as above described and as illustrated on the accompanying Drawings or
any mere modification thereof.
In witness whereof, I, the said Adam Carlisle Bamlett, have
hereunto set my hand and scal, this Fifth day of April, in
the year of our Lord One thousand eight hundred and seventy-
three
