PROVISIONAL SPECIFICATION. -
Improved Joint for Boxes, and Machine for Cutting the Wood to
Make the same.
I, JAMES HUNTER YOUNG, of Priory Bank, Castlehead Paisley, North
Britain, Timber Merchant, do hereby declare the nature of this invention to be
as follows:-
The object of this invention is to provide an improved joint for the sides and
ends of wooden boxes which when put together and the bottom fixed will be inter-
locked and cannot come asunder. In carrying out my invention I form angled
checks in the sides and ends. The sides and ends are put together at an angle by
fitting the tongues of one part into the angled checks in the other part. When
the bottom is fixed on a strong box is formed without nailing or gluing, the ends
and sides of which cannot come asunder.
The machine for cutting out these angled checks is constructed as follows:-On
a horizontal spindle a series of cutters is fixed with a space between each cutter
equal to the breadth of the cutter, the outer edges of the cutters forming a
portion of a cone. Between the cutters there is a sliding table with slots through
which the cutters get through. The surface of the table is parallel to the outer
edges of the cutters when in their highest position and the surface of the table
can be adjusted nearer to or farther from the outer edges of the cutters according
to the depth required for the angled checks. On the table a fence is fixed at an
angle to the spindle approximately equal to the inclination of the outer edge of
the cutters to the spindle.
The wood to be cut is placed on the surface of the sliding table and fixed
against the fence. The table then carries the wood past the cutters, and the
angled checks are cut out.
Instead of having the spindle horizontal I may make the table horizontal and
the spindle inclined so as to make the line of cutters in the highest position
horizontal.

COMPLETE SPECIFICATION.
Improved Joint for Boxes, and Machine for Cutting the Wood to
Make the same.
I, JAMES HUNTER YOUNG, of Priory Bank, Castlehead, Paisley, North
Britain, Timber Merchant, 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 object of my invention is to provide an improved joint for the sides and
ends of wooden boxes, which, when put together and the bottom fixed, will be
interlocked and cannot come asunder.

page_text: In carrying out my invention I form angled checks in the sides and ends. The
sides and ends are put together at an angle by fitting the tongues of one part into
the angled checks in the other part. When the bottom is fixed on, a strong box
is formed without nailing or gluing, the ends and sides of which cannot come
asunder.
The machine for cutting out these angled checks is constructed as follows. On
a horizontal spindle. a series of cutters is fixed with a space between each cutter
equal to the breadth of the cutter, the outer edges of the cutters forming a portion
of a cone. Between the cutters there is a sliding table with slots which the
cutters get through. The surface of the table is parallel to the outer edges of the
cutters when in their highest position, and the surface of the table can be adjusted
nearer to or farther from the outer edges of the cutters according to the depth
required for the angled checks. On the table a fence is fixed at an angle to the
spindle approximately equal to the inclination of the outer edge of the cutters to
the spindle.
The wood to be cut is placed on the surface of the sliding table and fixed against
the fence. The table then carries the wood past the cutters and the angled checks
are cut out.
Instead of having the spindle horizontal I may make the table horizontal and
the spindle inclined so as to make the line of cutters in the highest position
horizontal. The table and fence may be fixed and the cutters may be moved
along past the wood to be cut.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended an explanatory sheet of drawings in the several
figures of which corresponding parts are marked with the same letters of
reference.
Figure 1 is a plan of the machine.
Figure 2 is a vertical section.
Figure 3 shows one of the cutters.
Figure 4 is a piece of wood with the checks cut out.
A A A are a number of cutters fixed to the spindle B, the space between each
cutter being equal to the breadth of the cutters. The outer edge of the cutters
forms a portion of a cone. The sliding table C has slots formed in it through
which the cutters project. The surface of the table is inclined to the horizontal
spindle at the same angle as the conical surface. Thus the table is parallel to the
highest line of the cutters. The cutters can be made to project more or less
above the surface of the table by raising or lowering the framework carrying the
horizontal spindle B. This may be done by means of the hand wheel D and bevel
wheels E, F. The vertical spindle of the bevel wheel F has a thread cut on it
which works in a nut attached to the framework carrying the horizontal spindle.
On the table a fence G is fixed, the faces of which are inclined to the spindle at
an angle approximately equal to that of the outer edge of the cutters. The
wood to be cut is placed on the table and fixed against the fence by means of the
clamps H or I. The table with fence and wood to be cut is moved across
the cutters by means of the hand wheel J and toothed wheels K, L, M.
the spindle m of the toothed wheel M there is a pinion N which gears with a
rack attached to the framework of the table. As the wood is carried past the
cutters the angled checks are cut out.
.
Од
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. The machine for cutting angled checks and tongues substantially as
described.
2. In a machine for cutting checks in wood, the combination of a series of

page_text: cutters, the outer edges of which form a conical surface with a fence set at
approximately the same angle to the spindle of the cutters substantially as
described.
