A New Combination Link and Tine for Use in Making and Repairing
Chain Harrows, and for Increasing Friction on the Land.
I, GEORGE LEWIS, of Woodford, Berkeley, Gloucestershire, Agricultural
Implement Maker, 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 :-
My invention relates to a new combination for use in connecting the ordinary
links of chain harrows; and consists in making a link-tine from a bar of iron. or
steel, bending the same into a loop near each end, and turning the ends downwards
to form tines to scratch the land and separate the clods or lumps of manure; the
link-tine being available for repairing harrows when the links are broken.
In the manufacture of chain harrows as at present carried on, each link has to
be forged and united to those adjoining it by heating and then welding on the
anvil, which involves considerable labour in lifting to and from the forge, especially
when the harrow approaches completion. By the use of my combination link-tiue,
the harrow can be made in rows and sections, and these united without the.
application of heat, as the link-tine is closed by hammering when cold, and thus a
harrow can be made without lifting the whole of it into and from the forge, and at
the same time. the turned down ends will furnish double the number of points to
scratch the land.
My invention and the manner of carrying the same into effect, will be more
fully described in connection with the accompanying sheet of drawings, in which
Figure 1 represents a link-tine with a bow turned near each end, and the ends
turned down, each on the same side of the rod, to form tines; Fig. 2 is an end
view of the same, left open for the insertion of an ordinary link; Fig. 3. is another
end view of the same, after it has been closed around the link by hammering
it cold on an anvil or the. like; Fig. 4 is a view of a similar link-tine, but
with one bow and tine turned on one side of the rod, and the other on the
opposite side, which causes the two tines to operate in different lines or rows;
Fig. 5 is an end view of the same, showing the bow at each end left open for
receiving the link, and Fig. 6 is a view of the same when closed round the link.
Fig. 7 is a segment of a chain harrow, the rows of ordinary links connected by
link-tines as shown in Fig. 1; in this case the harrow travels in the direction
indicated by the arrow, and the tines operate at suitable distances between the
vertical ordinary links; Fig. 8 is also a segment of a harrow, where the rows of
links are joined by link-tines as shown in Fig. 4; when made with these, the path
of travel, as indicated by the arrow, will be in another direction, and the deviating
tines as shown in Fig. 6 will form two rows for scratching the land, instead of only
one, as is the case with ordinary links.
The link-tines are made from a bar of iron A of suitable length, the bows B
or B being formed as shewn, and the enls turned down to form tines, both on
one side, as C, where the tines are made vertical, or nearly so, or one on each
side, as C, in which case it is desirable to spread them on each side the rod,
as shewn in Figs. 5 and 6. The ends of the tines may be left blunt as shewn,
or brought to a point, or turned out at any couvenient angle, to form spreaders,
as indicated by dotted lines in Figs. 1, 2, 3, 4.

page_text: The construction of my improved link-tines and their use in the manufacture of
chain barrows will be fully understood from the drawings and description: the
link-tines are also used for repairing harrows, in the event of a link giving way,
one of the link-tines is inserted to connect the adjacent links, and the part C
hammered cold against the part A, and thus the harrow can be quickly repaired
by unskilled labour, without the annoyance and delay of sending it to the maker or
to a smith.
If it is preferred to use the harrow without the tines being in operation, the
harrow is turned over, when the tines will be uppermost, and produce no effect on
the land.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The construction of a combination link and tine for use in making and
repairing chain harrows, having the loops or bows left open for the reception of
the required links, and then closed cold by hammering the bows on an anvil or the
like, substantially as herein described and illustrated.
2. The construction of a combined link and tine for use in chain harrows, having
each end turned down to form a tine, whereby double the number of scratching
points are provided to operate on the land, substantially as described and shewn.
3. The construction of a combined link and tine for chain-harrows as described, in
which the ends or tines are set at different angles, whereby the scratching points
are more evenly distributed, substantially as shown in the drawings.
4. In the manufacture of chain harrows, the construction of links which will
enable the harrow to be made in rows or sections and united by the links which
are closed cold by hammering, substantially as described and shown.
