Improvements in Horse Rakes.
We, WILLIAM NEWZAM NICHOLSON and WILLIAM MATHER both of Newark-
upon-Trent in the County of Nottingham, Engineers, do hereby declare the nature
of our said invention to be as follows:-
The first part of our invention applies to an improved method of constructing
the rocking franes of horse rakes by the partial rotation of which the teeth
are lifted.
These rocking-frames as usually made consist of a bar turned at right-angles at
both ends and having formed on the ends so turned, round holes of such size as
will allow the rocking-frame to rotate on the round axle of the rake.
Our improvement consists in elongating and curving these holes in the rocking-
frame, so that in the act of rotation, the frame has a tendency to move forward
carrying the teeth with it and so altering the fulcrum as to materially lighten the
delivery of the rake as well as to allow the teeth to adjust themselves to irregu-
larities in the ground.
The second part of our invention applies to a plan by which after delivery of
the load the teeth of horse rakes adapt themselves on resuming their position for
raking to any unevenness of the land.
Instead of the locking links being constructed with the usual rule-joints, we form
in the upper link an elongated slot, in which a stud formed on the lower link is
allowed to traverse. We also fasten towards the centre of this upper link, a distance
piece having holes on the under side in such positions, that any of these holes will
receive a locking pin or stud forined at the end of the lower link. This locking pin
or stud is arranged to take into any one of the above named holes, thereby locking
the rake and holding the teeth in the position in which they fall, whether on the
level, on the ridge or in the furrow.

Improvements in Horse Rakes.
We WILLIAM NEWZAM NICHOLSON and WILLIAM MATHER both of Newark
upon Trent in the County of Nottingham Engineers, do hereby declare the nature
of our said invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement :―
Figure 1 on Sheet 1 of the accompanying two sheets of drawings repre-
sents so much of a horse rake as is sufficient to explain the first part of our
invention.
This consists in slotting or elongating and curving, if necessary, the holes C in
the rocking frame A, through which the axle B of the rake passes.
The rocking frame A is partially rotated round the axle B to lift the teeth of
the rake.
The effect of slotting the holes C is, that when the rocking frame A is rotated
round the axle B by the locking links D and E, it slides up the axle B in the
slot C thereby throwing the centre of gravity of the teeth further forward and
nearer the fulcrum; and at the same time the arm of the rocking frame A, to which
the locking link D is attached, is lengthened and the leverage increased as shown

page_text: by the dotted lines. The slots C in the rocking frame A also allow the teeth to
adjust themselves to the irregularities of the ground.
The second part of our invention is shown in Figure 2 Sheet 2. Instead of the
locking links being constructed with the usual rule joints, as shown in D and E
Figure 1, we form in the upper link D Figure 2 an elongated slot in which a
stud e formed in the lower link E is allowed to traverse. We also fasten or pivot
towards the centre of the upper link D a distance piece F having holes on the
under side in such positions that any one of the holes will receive a locking pin
or stud G, formed at the end of the lower link E. This locking pin or stud is
arranged to take into any one of the holes formed for it. in the under side of the
distance piece G, thereby holding the teeth in the position in which they fall,
whether on the level as shown in the full lines or on the ridge or in the furrow as
shown by the dotted lines.
Having thus described our invention we would have it understood that what we
claim is
1. In the rocking frames of horse rakes slotting or elongating or curving
the holes C surrounding the axle A for the purposes set forth, and shown in
Figure 1.
2. Slotting the locking links of horse rakes at their attachment so that they can
slide in combination with the locking stud G and the distance piece F or their
equivalents for the purposes set forth and shown in Figure 2.
