COME LIM DE MULLICATION.
An Improved Tool or Cutter for Planing and Shaping Machines.
We, WILLIAM HENRY CHAPPELL, Machinist, of No. 876 Mead Street and
WILLIAM HENRY PERKINS, Accountant, of No. 1233 West Adams Street both
of the City of Chicago, in the County of Cook State of Illinois, United States of
America, 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 relates to a tool for planing or shaping metals, and which
is intended for use in that type of planing or shaping machines, in which the metal
piece, or the tool has a rectilinear movement, with relation to each other.
The present improvement having for its object to provide a simple and efficient
tool or cutter for such uses, in the operation of which, at each stroke of the
planing or shaping machine, a series of independent and simultaneously successive
cuts will be taken, of the full depth required, the result being that a much wider
surface can be planed at each stroke of the machine, in a practical and
successful manner, than could be done with a single cutter of the same width of
cutting edge.
We attain such object by the construction and arrangement of parts illustrated
in the accompanying drawings, in which
Figure 1, is a plan view of the present improved tool or cutter for metal planing
or shaping machines.
Figure 2, a front elevation of the same.
Figure 3, a side elevation of the same.
Figure 4, a plan view of a piece of metal partly planed, with the points of the
series of obliquely arranged cutters of the present invention, shown in section and
in relative operative position.
Similar numerals of reference indicate like parts in the several views.
Referring to the drawings:
1, represents the body of the tool holder, and 2, the attaching shank thereof,
by which the tool holder is secured in place in the metal planing or shaping
machine.
3, are the series of cutters of the present invention, secured in or to the head or
body 1, of the tool holder in any usual and suitable manner.
In the construction shown in the drawing as illustrative of the present invention,
the series of cutters 3, are arranged in individual orifices in the head 1, and having
individual clamping screws 4, for securing and holding them in proper position.
In the present invention the series of cutters 3, have an oblique arrangement
with relation to the line of movement, and in a common and rectilinear plane, so
that each cutter point will remove an independent and simultaneously successive
cut of the full length and depth required; the result of the present view and
novel arrangement is that a series of independent straight cuts are planed along
the whole length of the piece of metal, regardless of its extent, each cut being
slightly in advance of the next succeeding one, and which after the cuts are beguo
the whole series of cutters are in operation during the interval that said cutters
move along the entire length of the metal surface that is being planed.

page_text: Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare what
we claim is:
1. A tool or cutter for planing or shaping machines, comprising in combination,
a head or holder, a series of independent cutters secured therein, and means for
clamping said cutters in place, the cutting points of said cutters being arranged in
a common and rectilinear plane, and obliquely to the line of movement, so that
each cutting point will remove an independent and simultaneously successive cut
of the full depth required, substantially as set forth.
2. A tool or cutter for planing or shaping machines, comprising in combination,
a head or holder having a series of orifices for the reception of the cutters, a series
of independent cutters arranged in such orifices and a series of set screws for
clamping said cutters in place, the cutting points of said cutters bei g arranged in
a common and rectilinear plane, and obliquely to the line of movement so that
each cutting point will remove an independent and simultaneously successive cut of
the full depth required, substantially as set forth.
