IMPROVE- MENTS IN REAPING MACHINES."
Year: 1868

page_text: LETTERS PATENT to Paul Kotzó, of Posth, in. the Kingdom of
Hungary, at present residing at Norfolk Street, Strand, in the City
of Westminster, Civil Engineer, for the Invention of "IMPROVE-
MENTS IN REAPING MACHINES.""
Scaled the 1st June 1869, and dated the 11th December 1868.
PROVISIONAL SPECIFICATION left by the said Paul Kotzó at the
Office of the Commissioners of Patents, with his Petition, on the
11th December 1868.
I, PAUL KOTZó, of Pesth, in the Kingdom of Hungary, at present
residing at Norfolk Street, Strand, in the City of Westminster, Civil
Engineer, do hereby declare the nature of the said Invention. for
"IMPROVEMENTS IN REAPING MACHINES," to be as follows:-
The object of this Invention is to obtain a direct movement for the
rakes or gatherers of reaping machines so as to bring them into a proper
position with respect to the level of the table or platform of the machine
without the use of complicated and cumbrous gearing. To this end a
bevil toothed wheel imparts motion to the knife bar, and on the back of
this wheel is cast or keyed a small bevil pinion, which gears with a

page_text: large bevil wheel mounted on the lower end of a shaft which turns
within and is held in position by a sleeve shaft. Upon the upper end
of the long inner shaft are keyed four arms united so as to form a cross
head, upon which the ordinary rake arms are fixed. The sleeve shaft is
set at such an angle that the rakes will come successively into the
proper position for sweeping up the corn on the table or platform.
On motion being communicated to the driving wheel the bevil wheel
will through the bevil pinion be caused to rotate, and thereby impart a
rotary motion to the shaft carrying the cross head, on which are fixed
the rake arms, and they are thus brought successively into the position
necessary for sweeping up the corn. By this arrangement, which may
be adapted to any of the ordinary reaping machines, the gearing is
greatly simplified, and a considerable saving of lubricating material is
effected, while from the greater simplicity and stability of the working
parts friction is to a great extent avoided.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Paul Kotzó in the Great Seal Patent Office. on
the 11th June 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PAUL
Korzó, of Pesth, in the Kingdom of Hungary, at present residing at
Norfolk Street, Strand, in the City of Westminster, Civil Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of December, 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 suc-
cessors, give and grant unto me, the said Paul Kotzó, Her special
licence that I, the said Paul Kotzó, my executors, administrators, and
assigns, or such others as I, the said Paul Kotzó, my executors, admi-
nistrators, 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
MACHINES," upon the condition (amongst others) that I, the said Paul

page_text: Kotzó, 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
5 in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patont.
NOW KNOW YE, that I, the said Paul Kotzó, 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
0 following statement, reference being had to the Drawing hereunto
annexed, and to the letters and figures marked thereon (that is to
say):
The object of this Invention is to ensure the efficient working of the
rakes and gathering arms of reaping machines by the use of a simple
construction of driving gear. This I propose to obtain by the employ-
ment of an inclined rake shaft, which when rotated will give the desired
rising and falling movements to the rakes and gathering arms, and cause
the latter to come into contact with the corn and gather it up to the
knives, and when the corn is cut enable the rakes to sweep the corn off
the platform on to the ground.
The manner of mounting this rake shaft and of actuating the same in
combination with a platform so shaped as to conform to the curve formed
by the sweep of the depressed rakes will be seen in the accompanying
Drawing, where Fig. 1 shews in side elevation so much of a reaping
machine as will serve to explain the nature of the Invention; Fig. 2 is
a plan view of the same, and Fig. 3 is an elevation, partly in section, of
the rear end of the machine.
A, A, is the rake shaft inclined, as shewn at Fig. 3, and mounted in a
ubular bearing A¹ supported by bracket castings, which form parts of
frame B. This frame is carried by the axle of the driving wheel C,
nd to it the draft pole D is secured by a fulcrum pin a and an adjustable
oupling b, which allow of the height of the platform and cutter bar
eing adjusted in the well-known manner. Keyed to the upper end of
he inclined shaft A is a cruciform head E, the arms of which are
ocketted to receive arms F, F', that carry respectively the rakes and.
athering boards. The driving wheel C is fitted with an internal toothed
heel c, into which gears a spur pinion d carried by a sleeve shaft on a
ud axle that is made fast to the frame B. On this sleeve shaft is also

page_text: keyed a bevil wheel e and a bevil pinion f, the latter of which gears into
a bevil wheel g' on the lower end of the rake shaft. The.bevil wheel e
serves to give motion to the cutter bar, which is connected to a crank H
carried by a short shaft I having its bearings in the frame B. The
opposite end of the shaft to that which carries the crank H is fitted with
a bevil pinion, which gears into and receives motion from the bevil.
wheel e. K is the platform curved to correspond to the sweep of the
rakes. It will now be understood that as the reaping machine is
advanced rotary motion will be communicated through the gearing
c, d, f, g, to the rake shaft, and the gatherers will be caused to press
the standing corn up to the cutters, and as the corn is cut the rakes
will advance, as indicated by the radial lines in Fig. 2. and sweep it off
the platform on to the ground.
Having now set forth the nature of the Invention of "Improvements in
Reaping Machines," and explained the manner-of-carrying-the-same-into
effect, I wish it to be understood that under the above in part recited
Letters Patent I claim, effecting the gathering up and discharge from
the platform of reaping machines of the cut corn by the means above
described.
In witness whereof, I, the said Paul Kotzó, have hereunto-set-my
hand and seal, the Third day of Junc, in the year of our Lord
One thousand eight hundred and sixty-nine.
PAUL KOTZÓ. (L.S.)
Civil Ingenieur.
