PROVISIONAL SPECIFICATION.
An Improvement in Self-binding Reaping Machines.
I, JAMES FORD, Saughton Hall, Mains Edinburgh, in the County of Midlothian,
North Britain, Farmer, do hereby declare the nature of this invention to be as
follows:-
-
This invention relates to an improvement in self binding reaping machines, and
has for its object to dispense with the upper canvas travellers or elevators between
which, as at present, the straw is caught up from the lower travelling canvas, and
is travellel up or elevated to the binder. In lieu of the said upper canvas or
elevator I employ a frame work of joggling or feeding rakes. The said rakes
consist of an arrangement of parallel bars preferably of half bar round iron
running lengthways at a slope from about the level of the lower or flat travelling
canvas to the upper part of the machine where the binder is situated. To the under
part of the said bars are fixed the teeth or prongs.
The rakes thus formed
are carried upon two cranked shafts for the top and bottom of the rakes; each
of the bars or rakes is carried upon an upper and lower crank and each alternate
bar or rake has opposite cranks, the arrangement being such that as the two shafts
are driven simultaneously an oscillating, scraping or joggling motion is given to the
rakes, the one set of alternate rakes taking the feeding or raking-up motion as the
other alternate set has just finished that motion. Behind or below the teeth
of the rakes is fixed to the machine a sloping board or back upon which the straw
is conducted by the rakes to the binder. In order to give the necessary raking
sweep to the rakes I mount the bars upon the cranks through the medium of
rocking journals, that is to say I pivot or hang the backs of the bars upon a
projection formed upon the under half of the bush upon the crank.
I may
actuate the cranked shafts by pitch wheels driven by the endless pitch chain at
present in use.

COMPLETE SPECIFICATION.
An Improvement in Self-binding Reaping Machines.
1, JAMES FORD of Saughton Hall Mains, Edinburgh, in the County of
Midlothian, North Britain, Farmer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :—
This invention which relates to an improvement in self-binding reaping machines,
has for its object to dispense with the upper canvas travellers or elevators between
which, as at present, the straw is led up from the lower travelling canvas to the
binder and to employ in lien thereof a framework of joggling or feeding forks.
As illustrated in cross section Figure 1, and part plan Figure 2 of the annexed
drawings the framework of joggling or feeding rakes consists of an arrangement of
parallel bars A, preferably of half round bar iron mounted in such a manner as to
run at a slope from about the level of the lower travelling canvas B to the upper
part of the machine C where the binder is mounted. The said bars A are provided
on their under sides with a suitable number of teeth or prongs a, so as to rake up
the straw from the canvas B over the sloping board or back D, which is secured to
the main framework E of the machine, to the binder. The said sloping board D is

page_text: preferably provided at its lower end with a ribbed or grooved roller F having a
number of curved sheet metal guards farranged at intervals along its length so as
to lead the straw on to the board D and so prevent the roller becoming choked; the
said roller F is driven by the ordinary chain driving gear of the machine.
In order to give the rake bars A, an oscillating, scraping or joggling motion I
mount each of them preferably by means rocking journal G and a fixed or
stationary journal H to two crank shafts J, which have each alternate crank
directly opposite each other as shown, so as to cause each pair of the rakes to go in
such a manner that when the one is leaving the straw the other one is entering it
and so forming a continuous oscillating or joggling rake, which is also greatly
assisted by means of the rocking journals G, which are formed with a pivotted
joint, by means of the lower half bush having a projection or tail piece formed
on it and which works in a suitable bracket which is secured to the bars A by
bolts or otherwise. The said bars are preferably connected at their top ends to the
top rail K, by means of two or more jointed links L, so as to prevent any side
movement or twisting of the cranks taking place.
The whole of the foregoing are driven by means of pitch wheels M and chain
from the ordinary driving gear of the machine, and the said chain may be either
the main chain or an auxiliary chain as desired.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what 1
claim is :-
1st. The general arrangement, construction and combination of the various parts
constituting my improvement in self binding reaping machines, all substantially as
hereinbefore described and shown in the drawings.
2nd. In self binding reaping machines the joggling or feeding rakes substantially
as and for the purposes hereinbefore described and shewn in the accompanying
drawings.
3rd. In self binding reaping machines the rocking journals G, substantially as
and for the purposes herein before described and shewn in the accompanying
drawings.
