Improvements in Apparatus for Cutting the Mitres for Doors,
Windows, Picture Frames, and the like, also applicable for
Outting Mouldings.
I, FRANK HUGHES, of the firm of Hughes Eli and Hughes of 76 Chancery
Lane London W.C. Patent Agent, do hereby declare the nature of this invention
(which has been communicated to me by Pierre Rotsaert, of Ixelles, near Brussels,
Belgium, Manufacturer) and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
In accordance with this invention the apparatus is a simple framework of any
desired dimensions, of wood, iron, or other material, formed open at the bottom
wherein are placed the strips of wood to be moulded; and in order that this
invention may be fully understood reference is had to the accompanying drawings,
and to the letters of reference marked thereon, and in which
Fig. 1 is an elevation of the machine and Fig. 2 a longitudinal section.
Fig. 1, is a vertical section and Fig. 21, is a similar view but with the mouldings
in positions.
Fig. 3, is a plan of the apparatus and Fig. 3¹, a vertical section shewing the
mouldings wedged in.
Any number of mouldings may be cut at one time but for simplicity of
illustration two only marked R in the drawings are here shewn. The saw works in
the channels R¹.
The apparatus is composed essentially of three pieces S. S¹ S", detachable, and
adjustable, and connected by screws, bolts, or other suitable means, in such manner
as to form an inverted U (n) shaped frame. The centre part S is formed with
inclined ends, and is interchangeable according to the size of the mitre it is desired
to cut. In the parts S¹S" which are identical are fitted vertical guides G G, and
inclined guides G G for holding the mouldings firmly in place, horizontally..
These guides G¹ G' are also interchangeable that their inclination, may agree with
the angle of the end of the centre part S. At the same time the inclined
guides G G acting in combination with the inclined ends of the centre piece S
determine together the incline of the saw cuts to be made. The stop piece B is
situated in the centre part S and is employed when cutting the mitres of cross
frames. TT are stop pieces for limiting the descent of the saw so that the sawing
may be exactly true as to depth of cut. As will be seen in Fig. 7 the stop piece T
which is adjustable in its position will serve upon being fixed at any required
position to limit the depth to which the saw shall cut by taking against the
traverse bar a of the saw when it arrives at such predetermined depth. V are
clamping screws to clamp the mouldings R. B₁ are bands encircling the apparatus
to strengthen same. V the adjusting screw for stop piece B. In Figures 2 and 2¹
are seen the mouldings R. Any number of these mouldings may be mounted but for
preference the number should not be more than 2 or 4. Clamping screws V are
employed for holding the mouldings firmly in position. The channels R¹ are fitted
with linings of copper or other metal. In Fig. 3' the mouldings R are shewn held
in position by jaws P. P with clamping screw V".
CC are wedges for wedging the pieces solidly together.
In Figs. 4 and 5 is represented a modification of the apparatus in sectional side-
and end elevation respectively. In accordance with this modification the sawing
may proceed in the two directions at an angle of 45° or only one side if desired
may be sawn.
Fig. 6 is a diagram of the cuts taken in the wood B, shewing a dovetail cut,.
and the corner cut unon one side only

page_text: In these figures B B are the pieces of wood to be acted upon placed through the
bottom opening of the machine in a perfectly straight and level position, which is
easily accomplished by letting their upper sides bear against the two pieces n n ou
each side; said pieces n n being fixed to a corresponding height by a regulating
screw, not shewn. S S are two screw clamps for holding the mouldings firmly in
the frame whilst being sawn.
The saws act in the channels R R. A A are two
stops for the saw so that the sawing may be exact and equal on both sides, and
T is a stop piece situated in the centre & similar to that marked B in Figure 2.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The improvements in apparatus for cutting the mitires for doors, windows, and
the like, and for cutting mouldings substantially as herein before described and
shewn in the accompanying drawings.
Dated this 20th day of May 1892.
