communication
Sealed the 12th August 1856, and dated the 4th April 1856.
PROVISIONAL SPECIFICATION left by the said George Tomlinson Bous-
field at the Office of the Commissioners of Patents, with his Petition, on
the 4th April 1856.
I, GEORGE TOMLINSON BOUSFIELD, of Sussex Place, Loughborough Road,
Brixton, in the County of Surrey, do hereby declare the nature of the
Invention for "IMPROVEMENTS IN MOULDING PLANES," to be as follows:-
This Invention consists in constructing moulding planes in such a manner
that the face of the plane may be readily separated from the body thereof, so
that many faces (having different mouldings thereon) may be used in con-
junction with one body. For this purpose, an angular piece of metal of the
same length as the plane is attached to the body so as to project beyond the
bottom thereof, and each of the moveable faces has a groove in its side to
correspond with the angular piece of metal attached to the body, and there
are thumb screws passing through the body, and screwing into metal nuts,
which are fitted into grooves in the moveable face, so as to clamp it firmly to
the body.

by the said George Tomlinson Bousfield in the Great Seal Patent Office
on the 4th October 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
TOMLINSON BOUSFIELD, of Sussex Place, Loughborough Road, Brixton, in the
County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent bearing dato the Fourth day of April, in the year of our Lord, One
thousand eight hundred and fifty-six, in the nineteenth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said George
Tomlinson Bousfield, Her special licence, that I, the said George Tomlinson
Bousfield, my executors, administrators, and assigns, or such others as I, the
said George Tomlinson Bousfield, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at
all times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN MOULDING PLANES," a communication, upon the condition
(amongst others) that I, the said George Tomlinson Bousfield, my executors
or administrators, by an instrument in writing under my or their, or one of
their, hands and seals, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Tomlinson Bousfield, do hereby
declare the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
This Invention consists in constructing moulding planes in such a manner
that the face of the plane may be readily separated from the body thereof, so
that many faces (having different mouldings thereon) may be used in con-
junction with one body. For this purpose an angular piece of metal, of the
same length as the plane, is attached to the body, so as to project beyond the
bottom thereof, and each of the moveable faces has a groove in its side to
correspond with the angular piece of metal attached to the body, and there
are thumb screws passing through the body and screwing into metal nuts,
which are fitted into grooves in the moveable face, so as to clamp it firmly to
the body.

page_text: And in order that the said Invention may be most fully understood, and
readily carried into effect, I will proceed to describe the Drawings hereunto
annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 (Sheet 1.) is a side view of a moulding plane constructed
according to the Invention; Figure 2 is a plan, Figure 3 an end view,
Figure 4 an under side view, and Figures 5 and 6 aro sections of the same,
taken respectively at the lines 1, 2, and 3, 4, of Figure 1. a is the body of
the plane, and b is a moveable face thereof; c is an angular piece of metal
fixed to the body a, and the moveable face b is grooved so as to fit into and
against the piece c; d and e are thumb screws, which screw into the nuts
f and g, having flanges f¹ g', which fit into undercut grooves b', b', in the
moveable face b. Thus, by turning the thumb screws d and e, the nuts f and
9 are drawn up, and the portions of the face 6 over the grooves b', 6', are
firmly nipped between the flanges on the nuts and the body of the plane, and
the body and face are thus held firmly together. h is the iron of the plane,
and i is the wedge by which it is set; j is an adjustable guage on the move-
able face to regulate the width of the cut by resting against the edge of the
board; the plane, as now arranged, being adapted to diminishing the thickness
of a board near its edge; k is another adjustable guage which regulates the
depth to which the plane will penetrate by coming in contact with the surface
of the board when the cut has reached the required depth; lis a small
additional cutter for clearing out the corner of the cut. Figure 7 is an
under side view of the body of the plane; Figure 8 is a plan; and Figure 9
a side view of the moveable face of the same; Figure 10 is a section taken
at the line 5, 6, of Figures 8 and 9. Figures 11 and 12 are separate views
of the thumb screws and nuts d, e, f, g. Figure 18 shews separate views of
the iron h.
Sheet 2 of the Drawings shows three other moveable faces and irons to be
substituted for the face 6 and the iron h (Sheet I.) Figure 1 is a plan,
Figure 2, an end view; Figures 3 and 3* are side views; Figure 4 is a
section taken at the line 1, 2, of Figure 3. Figure 5 shows the form of iron
adapted to this form of face. Figures 6 and 7 are similar views of other
forms of face and iron.
Sheet 3 shews another form of plane very similar to that shewn by Sheet I.,
but having a metal body in place of a wooden one. Figure 1 is a side view;
Figure 2, a plan; Figure 3, an end view; and Figure 4, a section taken at
the line 1, 2, of Figure 1. a is the metal body, and b is the moveable face;
d, e, f, and g, are the thumb screws and nuts, as before; h is the iron, which,

page_text: in place of being wedged in the ordinary manner, is held by the claw i, which
is made to bear tightly on it; by means of the thumb screw : Figure 5 is a
side view, and Figure 6 an under side view of the body, seen separately
Figure 7 shows the claw i and the thumb screw ; Figure 8 shews the
iron.
Having thus. described the nature of this Invention, and the manner of
performing the same, I would have it understood that I do not confine
myself to the exact details described; but what I claim is the constructing
moulding planes in such a manner that the face of the plane may be readily
separated from the body thereof, so that many faces (having different mould-
ings thereon) may be used in conjunction with one body.
In witness whereof, I, the said George Tomlinson Bousfield, have here-..
unto set my hand and seal, this Third day of October, in the year of
our Lord One thousand eight hundred and fifty-six.
