"IM-
PROVEMENTS IN FEEDING APPARATUS FOR THRASHING MACHINES
"
Our Invention relates to improvements in thrashing machine drum feeding
apparatus of the kind in which a set of yielding prongs or tinos combined or
alternated with a set of rigid prongs or tines, are arranged above the distributing
cylinder for the purpose of preventing the corn being fed in excessive quantities to
the drum. And the Invention has for its object to make the rigid tines adjustable
according to the desired rate of feed, and to enable the position and motion of the
yielding tines to be varied to suit the adjustment of the fixed tines
According to our Invention the rigid tines are all fixed to a stock or holder
provided with a screw adjustment whereby the said tines may all be raised or
lowered at once in order to set their points at the desired distance from the
distributing cylinder, and the tynes pass through a second bar or holder and
through slots in the cover or case, the said bar being fixed in position thereon by
set screws whereby the position or inclination of these tines relatively to the
distributing cylinder may be varied as required.
The yielding or clearing tines are attached to a rock shaft provided with a
weighted lever arm at right angles to the tines, the weight being capable of
adjustment to regulate the pressure required to deflect the movable tines and an
adjustable stop being provided to adjust their relative position to suit the fixed
tines.
The Invention also relates to a curved prong or prongs mounted on an axis
beneath the feed board and arranged to rise up through a slot or slots therein, the
point of the prong or prongs being directed and moving towards the distributing
cylinder for the purpose of assisting to convey the corn towards the said cylinder.
Oscillating motion is imparted to the axis from a crank on the distributing cylinder
shaft through adjustable connections whereby the motion of the prong or prongs

perfect guard this hood being pivoted to the case of the feeder at each end whercon
the hood is balanced by weights. These weights are fixed to lever arms at the
ends of the hood the arrangement being such that should a man fall onto the feeder
his weight must necessarily come on the hood and cause the latter to completely
close the mouth of the feeder or should a sheaf be thrown onto the hood the latter
will be caused to close the mouth of the feeder and will be restored to its proper
position by the counterweights on the removal of the sheaf. This hood prevents
all corn being lost.
In addition to the tines previously described I may also have two or three L
shaped tines suspended from a rod mounted beneath the top of the case and hanging
over the distributing roller-with-their-points-directed-backwards,_to_which_a_
rocking motion may be imparted from a crank or pin wheel on the distributing
roller shaft.
