page_text: LETTERS PATENT to Eliab Wright Pamplin, of Toversham, in the County of
Cambridge, Agricultural Engineer, for an Invention of "IMPROVEMENTS IN
MACHINERY, BEING SELF-FEEDING APPARATUS FOR THRESHING-MACHINES."
PROVISIONAL SPECIFICATION left by the said Eliab Wright Pamplin at
the Office of the Commissioners of Patents on the 18th February 1880.
ELLAB WRIGHT PAMPLIN, of Teversham, in the County of Cambridge, Agricultural
Engineer. "IMPROVEMENTS IN MACHINERY, BEING SELF-FEEDING APPARATUS FOR
THRESHING-MACHINES."
This Invention relates to improvements in the application of a self-feeding
apparatus for conveying to the drum of machines unthrashed grain from the stack,
barn, cart, or floor by means of an elevator constructed with two separate partitions,
one for protecting and distributing the grain as it is drawn upwards by chains or
belts fitted with spikes or blocks to the machine, the other to prevent waste of
loose or scattered corn, and to prevent accidents, to the workmen employed, on its
returning motion, the various speeds being obtained by unequal sized pulleys fixed
at the top end of elevator, and the chains or belts running over these and corre-
sponding pulleys at the bottom. The elevator is attached to a hopper fitted with
Oscillating boards attached to springs. Motion is obtained from the driving-spindle
of the elevator fixed over the beaters of the machine by round castings so constructed
as to make the elevator entirely self-acting, and so adjust itself to the required
elevation, and driven from the shaker or other spindles of threshing-inachine.

ELIAB WRIGHT PAMPLIN, of Teversham, in the County of Cambridge, Agricultural
Engineer. "IMPROVEMENTS IN MACHINERY, BEING SELF-FEEDING APPARATUS FOR
THRESHING MACHINES."
My Invention relates to improvements in threshing machines, and consists, first,
in the addition to said machines of a contrivance of a self-feeding apparatus for
conveying to the drum of the machine from any elevation or depression commen-
surate with the length of the platform hereinafter described, or along the top of said
machine unthrashed grain from the stack, barn, cart or floor; secondly, in an
improved clevating and lowering and distributing platform with two separate
partitions and removeable side-boards, and arranged in such a manner as to enable
it to be easily applied to either side of the threshing machine.
The mechanical arrangement of the self-feeding apparatus consists of a platform
for elevating and lowering and also an arrangement for conveying along the top of
the machine unthreshed produce, and constructed with two separate partitions, one
for protecting and distributing the corn as it is drawn towards the hopper, the
other to prevent waste of loose or scattered corn, and also to prevent accidents,
from the returning motion of the belts hereinafter described, to the workmen
employed in tending the machine. The corn is drawn towards the hopper by
various speeds (two, three, or more) of endless chains, india-rubber, or leather belts,
or other suitable appliances fitted with reversible projections of wood, iron, or other
suitable material, and of upright or vertical form at one side, and convex form at
the other side. These projections can be adjusted by the attendant so as to effect
more or less distribution as required. The chains, belts, or other suitable appliances
work over unequal sized sexagon or other suitable pullics, which are permanently
attached to the spindle or driving shaft which is fixed at the top of the aforesaid
platform, or they may be attached to separate shafts or spindles, or to the driving
spindle fixed to the machine itself. At the bottom of the aforesaid platform thero
is a corresponding number of pullies, round which said chains, belts, or other
suitable appliances work also. The pullies at the top of the aforesaid platform are
(as has been already stated) permanently attached to the spindle or spindles, and
when fixed on the driving spindle attached to the machine itself, as hereinbefore
mentioned, are also attached permanently thereto, so that they have the motion
thereof. The corresponding pullies as hereinbefore described are not so fixed, but
rotate freely round the spindle at the bottom of the said platform. Motion is imparted
to the various speeds of chains, belts, or other appliances hereinbefore mentioned
by the shaft or shafts at the top of the said platform, or by the shaft fixed to the
machine itself, as the case may be. The said shaft or shafts at the top of the said
platform are fixed over the beaters of the machine by round castings nioulded so as
to render the platform entirely self-acting, and to enable it to adjust itself to the
required elevation or depression. By these means the corn is conveyed direct to
the beaters of the machine from any required elevation or depression commensurate
with the length of the aforesaid platform.
For the better explanation and illustration of my said Invention I refer to the
accompanying Drawings. Figure 1 shows a side-elevation of the upper part of a
threshing machine with my self-feeding apparatus attached. A is the platform
placed in position at A¹, and containing the speeds of endless chains, belts, or other
suitable appliances B, B, B, as hereinbefore described; C is the hooded-hopper with
oscillating movements; D, D, D, are the unequal sized sexagon or other pullies, as
herein before described; E, E, E, are the pullies at the bottom of the said platform,
as herein before described. Figure 2 is a reverse section of the said platform,

page_text: showing the returning motion of the aforesaid speeds of chains, belts, or other
suitable appliances; Figure 3 shows the form of the aforesaid reversible projections;
Figure 4 shows the top of a threshing machine, and the mode of attaching and
working my self-feeding and distributing apparatus thereon. F, F, F, are the
unequal sized pullies fixed to the driving spindle, which is fixed to the machine
itself; G is the spindle fixed near the beaters of the machine.
Having thus fully described the nature of the said Invention I claim,—
First. The combination and arrangement of the herein before described self-feeding
apparatus for conveying and distributing to a threshing-machine, or along the top
thereof, unthrashed grain by various speeds (two, three, or more) of belts, chains,
or other suitable appliances working round pullies fixed to the spindle or spindles
at the top of the said platform, or to the driving spindle attached to the machino
itself, as hereinbefore described.
Second. The combination and arrangement of the platform with two separato
partitions, as hereinbefore described, and by means whereof the said platform is
rendered self-acting, and for facilitating the application of said platform to either
side of the machine.
Third. The herein before described reversible projections for enabling the aforesaid
apparatus to effect more or less distribution.
In witness whereof, I, the said Eliab Wright Pamplin, have hereunto set my
hand and seal, this Seventeenth day of August, in the year of our Lord One
thousand eight hundred and eighty.
Signed and sealed,
in presence of
