declare the nature of this invention to be as follows:-
This invention relates to a machine for making chips or shavings of wood.
The improved machine is constructed in such a manner that the fineness of the
chips or shavings can easily be regulated at will by varying the velocity of the feed
of the wood and the angle of penetration of the knives; and, if necessary, by changing
the knives themselves according to the width of the chips or shavings to be
obtained.
The machine is moreover arranged to work with a relatively small power.
The machine rests upon a bed carried by three feet.
At one extremity of the bed are arranged the mechanism for the transmission of
the motion, and comprising a shaft supported in two brackets and carrying the fast
and loose pulleys operated by the driving belt; a crank and fly wheel actuating the
knife holder through the medium of a connecting rod; and an excentric connected by
means of a rod to the apparatus for the advance and regulation of the pusher or feed
carriage for the block of wood to be reduced to chips or shavings.
At the other extremity of the bed is arranged the machine proper, comprising a
frame provided with guides in which the knife holder slides during its alternating
to-and fro motion.
Perpendicular to the surface of the machine is arranged a carriage capable of
sliding upon a guide way. The said carriage terminates in a plate which is applied
against the wood and in operation pushes it in a uniform manner. This carriage is
provided at its lower part with a nut which can be raised and lowered at will by
means of a cam lever so as to engage it with or disengage it from a screw.
This screw is set in rotation by means of an excentric, the said rod and a ratchet
wheel and pawl. A retaining pawl prevents any back motion of the ratchet wheel
during the back motion of the pawl.

page_text: At each to-and fro-motion of the excentric rod the ratchet lever pushes the ratchet
wheel and thus causes the screw to turn through a corresponding angle. The latter
then imparts to the nut and consequently, to the carriage and to the wood a forward
motion.
To regulate the velocity of this forward motion the point of attachment of the
excentric rod can be raised or lowered upon the pawl carrying lever; for this purpose
the said excentric rod is articulated upon a sleeve which can slide upon the said pawl
lever and which is kept in place when once regulated by a set screw.
The more the sleeve is raised the greater the amplitude of the angle described by
the screw for every revolution of the machine, and consequently the quicker will be
the advance of the wood and the coarser the chips or shavings.
To maintain the wood during its motion so that it cannot deviate from its recti-
linear position it bears on one side against the edge of the frame and on the opposite
side it is pressed by a griper arm articulated at the extremity of a lever, the large
arm of which is acted upon by a counterweight the chain of which passes over a guide
pulley so as to force the screw upon the wood.
Holdfasts, upon which act counterweighted levers, press against the upper surface
of the wood and prevent it from being lifted.
To vary the angle of penetration of the knives according to the required thickness
of the chips or shavings the knife holders are movable upon a vertical axis and bolts
serve to regulate them to the desired angle.
The knives are placed opposite each other, one being formed of a smooth blade and
the other cut in the form of teeth, so as to form a series of small blades separated by
spaces of equal width.
This latter knife supplies chips or shavings by making grooves in the wood during
the motion of the knives in one direction and during the return in the other direction
the smooth blade cuts the ribs which separates the grooves and thus produce chips or
shavings that are similar to those first cut. These two operations are repeated in
succession during every to-and-fro motion of the apparatus.

Chips or Shavings.
I, LOUIS ARBEY, of 95 Boulevard Beaumarchais Paris, France, Engineer, do hereby
declare the nature of this invention to be as follows:-

To vary the angle of penetration of the knives X according to the required thick-
ness of the chips or shavings the knife holders X' are movable upon a vertical axis,
and bolts X" serve to regulate them to the desired angle as shewn in Fig. 5 which is a
sectional plan of the knives and knife holder.
The knives are placed opposite each other, one being formed of a smooth blade and
