Feed Rollers for Chaff Cutting Machines.
I, ROBERT HENRY LANE, of Woodland House, Fair View, Cheltenham, Engineer,
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 relates to an arrangement of feed rollers for chaff cutting machines
by which the feed is automatically pressed during its progress through the box to
the cutting knife, avoiding the danger hitherto existing to the hands of the operator.
In accordance with this invention I provide two wooden or other suitable rollers
which I place across and within the box at any convenient distance from the mouth
of the chaff cutter. These rollers are preferably of different diameters and have
bearing pins at their ends passing through slots in the sides of the box and which
are connected to the ends of a quadrant arm upon each side of the box. These
quadrant arms work outside the box and are centrally pivotted to the sides of the
box. Immediately the hay comes in contact with the first roller it raises same in
accordance with the thickness of the feed and at the same time the second roller
is correspondingly depressed upon the feed, as it passes on to the cutter and thus
does the work hitherto performed by hand. The quadrant arm bearings may be
within a vertical slot in each side of the box, tightened and held in position by nuts
or the like, so that they may be readily adjusted to any thickness of feed.
And in order that this invention may be fully understood, I will now describe
same with reference to the accompanying drawings and letters and figures of
reference marked thereon, that is to say:
Fig. 1 is a side elevational view of a portion of the box of the chaff cutting.
inachine shewing the arrangement of quadrant arm carrying the rollers before
mentioned; and
Fig. 2 is a plan of the same.
Similar letters of reference indicate like parts in each figure.
a a are the sides of the box within which the rollers 66 are placed. cc are the
quadrant arms centrally pivotted at c¹ to the bearing pin d passing through the.
sides a of the box. ff are adjusting nuts. gg are the bearing pins above
mentioned at each end of the rollers 6 which pass through slots h Fig. 1 in the
sides a of the box and are connected to the ends of the quadrant arms c. When it
is desired to make the rollers adjustable in accordance with the thickness of the
feed these slots must be made of a sufficient width to allow play to the bearing
pins g notwithstanding the height at which the central pin d is adjusted, and as
shewn at e in dotted lines, (Fig. 1) vertical slots may be formed in the sides of the
box a in which the bearing pin may be adjusted at any desired height by nuts or
the like. Though not shewn relief springs may be added to the small roller as well
as to the bearing pin of the quadrant arms.

invention and in what manner the same is to be performed, I declare that what
I claim is:-
The feed rollers for chaff cutting machines constructed arranged, and operating.
substantially as hereinbefore described and shewn in the accompanying drawings.
