Improvements in Planes.
I, WILLIAM BEDDOWS of 1 Northumberland Avenue in the Town and County
of the Town of Nottingham, Joiner and Builder, 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, reference being had
to the accompanying drawings and to the letters and figures marked thereon, that
is to say:
My invention relates to improvements in side planes or those planes which are
known as side-rabbets, and are employed for smoothing quirks, bevelled shoulders,
and grooves in woodwork.
The object of the invention is to so construct side rabbeting planes that they
shall he of the requisite thinness and capable of smoothing the sides of very
narrow grooves. Furthermore, that the irons or bits of such planes shall be firmly
retained in place in the stock and yet be so arranged as to be capable of ready
removal therefrom for the purpose of sharpening, and be of a shape suitable for
sharpening.
For the purpose of my invention the stock, which is made preferably of iron,
steel, or gunmetal, is formed with a specially contrived bed or groove extending.
obliquely from the upper part to the lower edge of the stock, inclining transversely
from front to back, and canted laterally, said groove terminating in a mouth
formed at the side of the stock, and which may be at a suitable angle to the bottom
edge of the stock. Into this bed or groove thus formed, the plane iron, which is
slender, is received, and is retained in position by any suitable means, such for
instance as a retaining plate secured by a screw button; and the cutting edge of
the plane iron is inclined at an angle to suit the inclination of the mouth. The
planes can be made right or left handed.
And in order that my invention may be readily understood and be carried into
effect, I will describe the same with reference to the annexed drawings.
Fig. 1 is a side elevation, Fig. 2 an end elevation, Fig 3 a cross section on the
line, a, of Fig. 1, and Fig. 4 a plan showing a plane constructed in accordance
with my invention.
Figs. 5 and 6 show respectively a face and edge view of the plane iron.
Fig. 7 is a detailed sectional view of the retaining plate hereinafter more fully
referred to.
In Fig. 4 the plane iron and the retaining plate are removed, in order that the
bed or groove may be more clearly seen.
Fig. 8 is a plan and Fig. 9 an end view showing a modified construction of plane.
Referring more particularly to Figs. 1 to 7, is the stock and is the specially
contrived channelled bed or groove into which the plane iron c is received and
retained firmly in place by means of the sides of the groove and the retaining
plate d, and screw e.
As will be seen by the drawings, this bed or groove, not only inclines from top
to bottom of the stock, as seen in Fig. 1, but is also canted laterally and slants
transversely from front to back, as seen in Fig. 3, where it terminates in an
inclined mouth through which the angular cutting edge g of the plane iron slightly
protrudes when this latter is in place in the stock. The angular cutting edge g
may form any desired angle with the edge of the plane iron. The angle, or
amount of slant, given to the bed or groove may be varied according to the shape
of the stock.
The retaining plate d is furnished with a ledge or Hange d' which bears upon the
plane iron when the screw e is tightened up. This screw is shown as passing

page_text: centrally through the retaining plate d, and is tapped into the stock a; but if
preferred said plate d may be retained in position by means of a counter-sunk bolt
provided with a nut; or by making the plane iron triangular in cross section, the
ledge of flange on the retaining plate may be omitted.
In the modified construction shown in Figs. 8 and 9, the plane iron is retained
in place by means of a wedge h, the retaining plate and its screw being dispensed
with. In this construction the upper part of the stock a is enlarged so as to
receive the plane iron and wedge, and this latter is driven into place in the bed or
groove, from one end of the plane, and thereby forcibly holds the iron within its
bed or groove.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. A side rabbeting plane having its stock formed with a canted bed or groove
which extends obliquely from the upper part to the lower edge of the stock and
inclines transversely from front to back thereof where it terminates in a mouth
formed at the side of the stock, and into which bed or groove the plane iron, pro-
vided with an angular cutting edge, is received and is maintained by suitable
means, substantially as hereinbefore described and as shown with reference to the
drawings.
2. In side rabbeting planes, constructed as above claimed, the means for securing
the plane iron in place in the stock, consisting of the plate d preferably formed
with a ledge or flange d adapted to bear on the plane iron, and of the screw e for
tightening up such plate, as described and shown.
3. In side rabbeting planes, as above claimed, the arrangement of the mouth
inclining towards the back end of the plane, substantially as described and shown.
4. The modified construction of side rabbeting plane, as described and shown
with reference to Figs. 8 and 9 of the annexed drawings.
5. My improvements in planes substantially as described and shown.
