IMPROVEMENTS IN MACHINERY FOR REAPING AND MOWING
Year: 1868

page_text: LETTERS PATENT to Adam Carlisle Bamlett, of Thirsk, in the County
of York, Agricultural Engineer, for the Invention of "IMPROVEMENTS
IN MACHINERY FOR REAPING AND MOWING."
Sealed the 22nd May 1869, and dated the 27th November 1868.
PROVISIONAL SPECIFICATION left by the said Adam Carlisle Bamlett
at the Office of the Commissioners of Patents, with his Petition, on
the 27th November 1868.
I, ADAM CARLISLE BAMLETT, of Thirsk, in the County of York, Agri-
cultural Engineer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MACHINERY FOR REAPING AND MOWING," to be as
follows:-
This Invention relates to certain new and useful improvements in
machinery used for reaping and mowing.
The first part of the Invention consists of a sliding segment of a cam
applied to that class of reaper with self delivery at the back of the

page_text: machine which delivers a sheaf for each revolution of the reel, the object
of the sliding cam being to make it deliver two sheaves for each
revolution of the reel. The segment of a cam is fitted loosely on the
reel shaft, and can be placed in working position or withdrawn by a
lever similar to a clutch lever.
The second part of the Invention consists in placing a small wheel on
the outside shoe in advance of the knife, which in crossing furrows
prevents the fingers running into the ground.
And the third part of the Invention consists in the better lubrication
of the bearing where the knife is connected to the connecting rod; that
part of the connecting rod is made hollow, thereby causing it to act as
an oil cup, and thus lubricating that bearing in a much better manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Adam Carlisle Bamlett in the Great Seal Patent
Office on the 26th May 1869.
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 Twenty-seventh day of November, in the
year of our Lord One thousand eight hundred and sixty-eight, in the thirty-
second 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, adminis-
trators, and assigns, or such others as I, the said Adam Carlisle Bamlett,
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 MACHINERY FOR REAPING AND MOWING," upon the con-
dition (amongst others) that I, 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

page_text: 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 Adam Carlisle Bamlett, do hereby
declare the nature of my 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 Sheet of Drawings, that is to say :--
This Invention relates to certain new and useful improvements in
machinery used for reaping and mowing.
The first part of the Invention consists in the use of a sliding segment
of a cam applied to that class of reaper with self delivery at the back of
the machine, and which delivers a sheaf for each revolution of the reel,
the object of the improved or sliding cam being to make it deliver two
sheaves for each revolution of the reel. The segment of a cam is fitted
loosely on the reel shaft, and can be placed in working position or
withdrawn by a lever similar to a clutch lever.
The second part of the Invention consists in placing a small wheel
on the outside shoe in advance of the knife, which in crossing furrows
prevents the fingers running into the ground.
And the third part of the Invention consists in the better lubrication
of the bearing where the knife is connected to the connecting rod; that
part of the connecting rod is made hollow, thereby causing it to act as
an oil cup, and thus lubricating that bearing in a much better manner.
Such being the nature and object of my said Invention for " Improve-
ments in Machinery for Reaping and Mowing," 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 a Sheet of
Drawings illustrative thereof, and have marked the same with figures and
letters of reference corresponding with those in the following explanation
thereof, that is to say:-
The first part of my Invention consists in the use of a sliding segment
of a cam, and is shewn on the accompanying Sheet of Drawings (which
illustrates sufficient of the details of reaping and mowing machines to

page_text: explain my Invention) at Figures 1 and 2, and is an improvement on
that class of reaper which delivers the sheaf by the joint action of the
reel and the tilting platform. The tilting platform is at present worked-
by a cam similar to that shewn at Figure 3, which delivers a sheaf at
every revolution of the reel shaft. Now my improvements, as shewn at
Figures 1 and 2, will deliver either one or two sheaves (as may be,
desired) for every revolution of the reel shaft, a is a pulley; b, two
runners or bosses (cast or mounted on the arms of the pulley); and c,.
the improved sliding cam which slides on the reel shaft. The improved
cam has a groove turned on it (shewn at d, Figure 2,) for an ordinary
clutch lever placed within convenient reach of the driver, and when it is
desired to deliver one sheaf for each revolution of the reel shaft the
improved segment of cam is slid close up to the pulley a, the position
being partly shewn in dotted lines at Figure 2, thereby forming a cam
similar in its action to the one now in general use (illustrated at
Figure 3). When it is desired to deliver two sheaves for each revolution
of the reel shaft the cam is slid back into its former position.
The second part of my Invention, illustrated at Figures 4 and 5,
consists in mounting a small wheel e on the shoef to prevent the fingers g
sticking into the ground in crossing furrows, at which time the small
wheel e comes in contact with and runs along the ground; h, Figure 4,
shows the position of the wheel which carries the finger bar on the corn
side, and i, the position of the driving wheel.
The third part of my Invention consists in a better mode of.
lubricating or oiling the bearing where the knife is connected to the
connecting rod, and is illustrated at Figures 6 and 7. That part of
the connecting rodj which takes into the knife eye is made hollow at k
and is filled with oil (through the hole 1), which flows into the knife eye
through the hole m and through the holes n, thereby effectually
lubricating the knife slide.
Having now described the nature and object of my said Invention for
"Improvements in Machinery for Reaping and Mowing," 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 employment or use of a sliding cam as herein-before
described, and as illustrated (at Figures 1 and 2) on the accompanying
Sheet of Drawings for the purposes herein-before set forth.

page_text: Secondly. The employment or use of a small wheel as described, and
as illustrated at Figures 4 and 5 on the accompanying Sheet of
Drawings, for the purposes herein-before set forth.
And, thirdly. The improved mode or method of lubricating the
bearing of the connecting rod and knife as described, and as illustrated
at Figures 6 and 7 on the accompanying Sheet of Drawings.
In witness whereof, I, the said Adam Carlisle Bamlett, have
hereunto set my hand and seal, this Twenty-fifth day of May, in
the year of our Lord One thousand eight hundred and sixty-ninc.
ADAM CARLISLE BAMLETT. (L.S.)
