Improvements in Grafting Machines.
We, JEAN CHEVRETON and STÉPHANE RIVIÈRE, both Citizens of the Republic
of France, and residing at St. Chamond, Loire, France, 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:-
-
The present invention has reference to horticultural implements and the special
object thereof is to provide a simple but substantial device, specially constructed
and combined for grafting and like purposes and allowing the gardener and even
those who are not skilled in the art, to cut away the branches to be grafted very
easily and readily and by one operation only.
The grafting machine, contemplated as an object by the present invention
consists in a simple lever pivotted to a base or its equivalent and carrying three
knives, adapted to cut the necessary incisions in the twigs or branches to be
grafted by a simple depression of the lever of the device, the same having been
previously raised and the twig placed upon a suitable support provided on the
machine.
Our improvements consist in the arrangement and combination of parts, more
clearly and fully pointed out and claimed hereinafter and illustrated in the
accompanying drawings, in which ;-
Figure 1 is a side elevation of the improved implement embodying our
invention.
Figure 2 is a plan view of same, and
Figure 3 shows two twigs or branches a and b with the necessary incisions for
grafting successively effected by the knives of the implement.
In these drawings, like letters refer to like parts throughout all the figures.
The letters A, B and C represent three knives, indicated by dotted outlines.
The machine comprises an oblong base 1, provided with suitable foot pieces 2
to secure it to a board, a table or the like, said base being preferably made of
cast iron, however any other material may be employed for its manufacture;
the base 1 has an extension or standard 3 at the rear end thereof, secured to or
made one with said base and to the upper end of which is pivotted a lever 5,
by means of the journal 4 movably held in bearings on said standard 3. The
opposite end of the lever 5 is provided with a handle 6, and the lever is guided,
as it is raised or depressed, by the curved post 7 rectangular in cross section
secured at 8 to the base 1 of the machine and extending through a correspond-
ing slot in the body of the lever. The portion of the lever indicated by
numeral 9 and comprised between said slot and the handle 6, has an arched
shape, the lower fore end 10 of which carries the knife A, fitted into a slot in
said end and adjustably held therein in any suitable manner. On the left of
lever 5, and extending through a slot provided in an extension 11 on the under-
side of said lever, there is a second knife B, also adjustably held in its slot in
any suitable manner. The knives A and B are thus arranged parallel with the
longitudinal axis of the lever. On the right of lever 5 there is another exten-
sion 12, provided with slot 13, through which extends a third knife C, adjust-
01

page_text: ably held therein in any suitable manner, and placed obliquely with respect to
knives A and B, that is, with respect to the longitudinal axis of the machine.
From the aforegoing construction it will be seen that the knives. A, B and C,
which may be of any suitable shape, are situated in three different planes for the
purpose hereinafter described.
The machine carries furthermore a suitable support 14 secured to the base 1
and adapted to receive and hold the twig or branch to be grafted.
The operation of my improved grafting machine is as follows:-The lever 5
is raised to the top of curved post 7 and the twig or branch a-to be grafted then
laid upon support 14. Now the operator quickly depresses said lever 5 whereby
the knife A first cuts said twig or branch a on line 15 as shown in Figure 3;
the second knife 1 then makes a cut 16 a little further on said twig and extend-
ing parallel with cut 15 to the centre of same, and finally the third knife C cuts
the twig or branch a longitudinally on its axis 17, the end of said twig or branch
being thus formed as shown in Figure 3 of the drawings. It will be obvious that
a second twig or branch 6 operated upon in a similar manner, will be very easily
grafted to twig a, by applying the faces 15, 16 and 17 on twig a upon the faces
151, 16 and 17' on twig b.
We wish it to be understood that we do not confine ourselves to the particular
construction and the precise arrangement of the parts as shown in the accom-
panying drawings so long as the principle of our invention be retained.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is:-
(1) In a grafting machine, a suitable base 1 having a support or standard 3,
in combination with a lever 5 pivotted to said standard, three knives A, B
and C carried by said lever, means for guiding said lever as the same is moved,
and means for supporting the twig or branch to be grafted, substantially as
described.
(2) In a grafting machine, a suitable base 1 having a standard 3, in com-
bination with a lever 5 pivoted to said standard, three knives A, B and C carried
by said lever, a curved post 7 secured to said base and guiding said lever as the
same is raised or depressed, and means for supporting the twig or branch to be
grafted, substantially as described.
(3) In a grafting machine, a suitable base 1 having a standard 3 or its equiva-
lent, in combination with a lever 5 pivotted to said standard, three knives A, B
and C placed in three different horizontal planes and carried by said lever, a
curved post 7 secured to said base and guiding said lever as the same is moved,
and a support 14 secured to said base and supporting the twig or branch to be
grafted, substantially as described and shown."
(4) In an implement of the class described a pivoted lever carrying three knives
adjustably secured thereto in any suitable manner and situated in three different
horizontal planes, one of the knives being placed obliquely with respect to the
other two, substantially for the purpose set forth.
(5) In an implement of the class described the arrangement of three knives
situated in three different horizontal planes, one of the knives being placed
obliquely with respect to the other two, substantially for the purpose set forth.
