PROVISIONAL SPECIFICATION.
Improvement in Machinery for Sawing Wood for Frames, Boxes
and Articles of a kindred nature by Means of Guides.
EDUARDO PEDRAZZOLLI of No. 18 Camden Passage Islington in the County
of Middlesex Musical Instrument Maker do hereby declare the nature of this
invention to be as follows:-
This invention relates to a machine or apparatus for guiding saws in cutting
wood for use in the manufacture of picture frames and boxes and similar articles
where a bevel or mitre is required and which dispenses with the use of the mitre
shooting board. The present apparatus has for its object an improved method of
cutting wood by sawing with an ordinary saw between steel guides which can be so
arranged as to guide the saw either straight or diagonally at any required angle
and by elevation or depression to produce any bevel that may be desired.
The invention consists of (1) a wooden block or bench (Figure 1) with protruding
feet (a) (a) for clamping to an ordinary bench, hollowed out at the sides (6) with a
hole drilled through (c). (2). An iron or other metal plate Figure 2 with two
parallel slots (d) (d) for adjusting the guides on the front side and a corresponding
plate (Figure 3) with parallel slots (e) (e) for adjusting the guides at the back
each plate being drilled with a hole to correspond with the hole (c) in the wooden
bench.
The guides consist of a pair of steel blades (Figure 4) with a hole corresponding
with the hole (c) in the block and plates and a number of smaller blades or
guides (Figure 5) drilled with two holes (ƒ) (ƒ) at their lower end for the reception
of screw bolts.
The iron plates are firmly screwed on either side of the wooden block the
requisite number of screw bolts having been first passed through the slots the heads
being behind the plates in the hollowed out sides of the block and the screws
protruding outwards. The guides (Figure 5) are then laid on either side the
The guides
screws passing through the holes ff and are made fast with nuts
(Figure 4) are fixed by means of a screw bolt passing from back to front through
the holes (c) and secured with a fly nut. The apparatus is then complete
(Figure 6).
The steel guides are all capped with lead to prevent injury to the saws and are
bevelled in different directions those at the front to correspond with those at the
back. By loosening the nuts the guides can be slid backward or forward on either
side enabling the front and back guides to form any angle required for cutting
diagonally while by the same means the guides can be either elevated or depressed
so as to slant to any degree and produce any bevel that may be requisite.

EDUARDO PEDRAZZOLLI of No. 18 Camden Passage Islington Green London N.
Mandolin Manufacturer 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 relates to a machine or apparatus for guiding saws in cutting wood
for use in the manufacture of picture frames boxes and similar articles where a
bevel or mitre is required and which dispenses with the use of the mitre shooting
board or with the necessity of shooting at all.
The present apparatus has for its object an improved method of cutting wood by
sawing with an ordinary saw between the steel guides which can be so arranged as
to guide the saw either straight or diagonally at any required angle and by elevation
or depression to produce any bevel that may be desired.
The invention consists of; (as shewn in the drawing accompanying my Provisional
Specification)
Figure 1. a wooden block or bench with protruding ends (a) (a) for clamping
to an ordinary bench hollowed out at the sides (b) and with holes drilled
through (c).
Figure 2. is an iron or other metal plate with two parallel slots (d) (d) for
adjusting the guides on the front side and a corresponding plate (Figure 3) with
parallel slots (e) (e) for adjusting the guides at the back each plate being drilled
with a hole to correspond with the hole (c) in the wooden bench.
The guides consist of a pair of steel blades (Figure 4) and a hole corresponding
with the hole (c) in the block and plates and a number of smaller blades or guides
(Figure 5) drilled with 2 holes (f) (f) at their lower end for the reception of
screw bolts.
The iron plates are firmly screwed on either side of the wooden block the
requisite number of screw bolts having been first passed through the slots the heads
being behind the plates in the hollowed out sides of the block and the screws
protruding outwards. The guides (Figure 5) are then laid on either side the screws
passing through the holes (f) (f) and are made fast with nuts. The guides
(Figure 4) are fixed by means of a screw bolt passing from back to front through
the holes (c) and secured with a fly nut.
The steel guides are all capped with lead (Figure 6) to prevent injury to the
saws and are bevelled in different directions those on the front to correspond with
those at the back. By loosening the nuts the guides can be slid backward or
forward on either side enabling the front and back guides to form any angle
required for cutting diagonally while by the same means the guides can be either
elevated or depressed so as to slant to any degree and produce any bevel that may
be requisite.
In the drawing accompanying this Complete Specification Figure 1 is a plan
view of the mitre cutting block.
Figure 2 is a sectional view of a detail of an additional means for sawing wood
for frames boxes and articles of a kindred nature by means of the guides.
In such figure I shew that the block is cut in two equal parts from end to end
and that by means of two screws the said block can either be permitted to remain
in its original position before its severance or it may be widened to the extreme
length of the screws or bolts thereby enabling the craftsman to cut wood of a wider
nature than prior to the alteration. These screws or bolts are represented by the
letters A in Figures 1 and 2 herewith.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare what I
claim is
An improvement in machinery for sawing wood for frames boxes and articles of
a kindred nature by means of guides substantially as described and for the purposes
set forth.
