& Co., Patent Agents, Southampton Buildings, London, for an Invention of
"IMPROVEMENTS IN CARPENTERS' OR JOINERS' PLANES." A communication

PROVISIONAL SPECIFICATION left by the said William Robert Lake at the
Office of the Commissioners of Patents on the 13th October 1880.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent
Agents, Southampton Buildings, London. "IMPROVEMENTS IN CARPENTERS' OR
JOINERS' PLANES." [A communication from abroad by Pierre Brunet and Victor
Brossier, both of Paris, France.]
This Invention relates to improvements in carpenters' or joiners' planes.
According to the said Invention I make a plane in such a manner that it has
only one iron, the latter being provided with a double bevelled edge at the cutting
end. This improved plane is extremely simple in construction and possesses
important advantages.
The chief object of the said Invention is to provide means for dispensing with
the second iron or plate employed in ordinary planes, whose slot or opening
becomes readily choked or blocked with shavings.
In practising the said Invention I provide the wood block or body of the plane
with two mortises or apertures extending through the said block or body, one
being designed to receive the shavings, and the other to contain the plane-iron
and the wooden wedge or key for holding the same in place. The said apertures
or openings taper in such a manner that they are wider at the top than at the
bottom thereof. The said iron is made at its lower extremity with double,
inclined, or bevelled edges, and the cutting blade which is made of steel is let into
the iron centrally and extends a suitable distance along the same in an upward
direction, the edge of the said steel blade which effects the cutting of the wood
being bevelled to correspond with the edges of the plane iron. The faces of the
bevelled portion may be at any angle most suitable for the work to be effected.
The iron may be readily taken out of the wood block or fixed therein, and the
setting or sharpening, also the adjustment, are effected in a very simple manner;
moreover the aperture or opening for the exit of the shavings being perfectly free
and clear no choking of the tool can take place.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent
Agents, Southampton Buildings, London. IMPROVEMENTS IN CARPENTERS' OR
JOINERS' PLANES." A communication from abroad by Pierre Brunet and Victor
Brossier, both of Paris, France.
This Invention relates to improvements in carpenters' or joiners' planes.
According to the said Invention I construct a plane which has a single bit or
iron, and I dispense with the break iron used in planes of the ordinary construction,
whose throat or aperture becomes easily choked or blocked with shavings.
This improved plane is extremely simple in construction and possesses other
important advantages.
The aforesaid bit or iron which has a doubly bevelled edge is provided with a
steel blade or cutter, the said bit or iron being held in its place by a wooden
wedge or key. The cutter is easily sharpened and the plane is not liable to
become choked.
My improved plane is illustrated in the accompanying Drawing, in which
Figure 1 is a longitudinal vertical section of the said plane, and
Figure 2 is a plan of the same.
Figure 3 is a horizontal section on the line A, B, Figure 1.
As shewn in the Drawing the stock a of the said plane has two rectangular
taper mortises or apertures b, c, the first serving for the disengagement of the
shavings, whilst the second serves for the reception of the bit or iron d and of the
wooden wedge e, whereby it is held in its place. This bit d is at its lower end
bevelled in two directions, the two faces being formed with any angle or
inclination required for ensuring the proper action of the plane. In the centre of
this bit between two thicknesses of iron is placed and secured the steel blade f, the
edge of which serves to cut the wood.
As will be readily understood it is very easy to separate the parts of this plane,
to sharpen the cutter, and to adjust the same, and the throat or aperture 6 being
quite free will not become choked or obstructed.
Having thus fully described the said Invention as communicated to me by
my foreign correspondents and the manner of performing the same, I wish it
understood that I claim a plane, constructed as above set forth and as illustrated
in the Drawing, which plane is chiefly characterized by the following novel features,
that is to say:-
The absence of the break-iron.
The peculiarly constructed single iron or bit, which has a doubly bevelled edge
and is fitted with a steel blade or cutter, and
The stock of the plane provided with inclined apertures formed and arranged
as shewn.
All substantially as and for the purpose set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Thirteenth day of April, in the year of our Lord One
thousand eight hundred and eighty one.
