Improvements in Grafting Tools.
I HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby
declare the nature of this invention to be as follows:-
This invention is chiefly designed to provide the vine grower with a tool by
means of which he can effect the grafting of vines in a perfect and rational
manner.
The operation succeeds perfectly when the graft to be inserted into the vine
presents a cut corresponding exactly to a projection provided on the branch of the
vine which is to receive the graft in such a manner that the juxtaposition of the
two parts shall be accurate without producing any break either in the ligneous part
or in the surrounding bark. The bark when the grafting has been effected must
not present any irregular break of continuity.
•
In order to obtain this result I have devised an improved grafting tool having
two jaws which a spring tends to keep open. One of these jaws presents two
converging planes comprising between them a plane angle. The second jaw is
composed of two taper cutting blades pivoted at the end of the first blade and
converging into a point so as to be perfectly adapted to the outer faces of the first
jaw and to embrace them exactly.
If the extremity of the graft is introduced into the tool in one direction and the
jaws are then closed a piece is cut off which is comprised between the convergent

planes meeting together at the point of the grafting tool.
in the central part of the graft a cut terminating in a point. If on the other hand
the grafting tool is applied to the vine which is to receive the graft, that is to say
if the branch of the vine to be cut is introduced into the tool in the opposite
direction to that above mentioned, two lateral portions are cut off leaving at the
extremity a pointed tooth. The two cuts being effected by means of two exactly
corresponding surfaces the two parts being adapted between them in an accurate
manner.
With this grafting tool any person can graft from three hundred to four hundred
vines a day. The improved tool may be used for grafting fruit trees and also
flowers and the like.

Improvements in Grafting Tools.
I HENRY HARRIS LAKE of the firm of Haseltine Lake & Co. Patent
Agents 45 Southampton Buildings in the County of Middlesex 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 is chiefly designed to provide the vine-grower with a tool by
means of which he can effect the grafting of vines in a perfect and rational

page_text: The operation succeeds perfectly when the branch which is to be grafted upon
the vine presents a cut corresponding exactly in shape to a projection carefully cut
on the branch of the vine which is to receive the graft in such a manner that the
fit of the two parts shall be perfect and without any break of contact either in the
woody part or in the surrounding bark. The bark when the grafting has been
effected, must not present any irregular or broken edges.
In order to obtain this result I have devised the grafting tool represented in the
accompanying drawing.
Figure 1 is a lateral side view of my grafting tool the jaws being open.
Figure 2 is a front view of the same.
Figure 3 is a section on the line ay Figure 1.
Figure 4 a section on the line W Z also of Figure 1.
C
A spring a tends to keep the two jaws open. These jaws are formed as follows.
The jaw A Figures (1, 2, 4) is formed of two planes bed and be converging
at and comprising between them a plane angle of which be is the edge. The
second jaw B is composed of two taper cutting blades fg pivotted at C at the base
of the first mentioned blade A and converging to a point near b so as to be perfectly
adapted to glide over the outer faces of the jaw A and to embrace them exactly.
If the extremity of the graft is introduced into the tool in the direction of the
arrow P, and I close the jaws one upon the other a piece is cut off which is
comprised between two convergent planes which meet together at the point of the
grafting tool. In other words I make in the central part of the graft a cut
terminating in a point. If on the other hand the grafting tool is applied to the
vine which is to receive the graft, that is to say if the branch of the vine to be cut
is introduced into the tool in the opposite direction to that above mentioned that is
to say the direction indicated by the arrow Q two lateral portions are cut off
leaving at the extremity a pointed tooth. The two cuts being effected by means
of two exactly corresponding surfaces the two parts are adapted to fit together in
an accurate manner.
With this grafting tool any person can graft from three hundred to four hundred
vines a day. The improved tool may be used for grafting fruit trees and also
plants of other descriptions.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondent I declare that what I claim is.
A grafting tool characterized by the simultaneous employment of two jaws
embracing one another and which by changing the respective positions of the
branches of trees or plants with regard to the tool may be employed either for
providing the said branches with projections or with notches so that the said
projections may be fitted accurately to the notches in a geometrically perfect
manner.
