I, CHARLES FREDERICK PARSONS of 101 Ormside Street, Old Kent Road,
Surrey, Engineer, 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 an improved construction, or arrangement, of combined
wood sawing and slicing machines of a kind similar to that Patented by me on
the 7th January 1884, N° 896, but in which the saws have a horizontal reciprocating
action and the slicing knives a vertical reciprocating action both acting with the
grain of the wood but transversely to each other and not from the end of the grain
to sever the wood after the saws have cut it into slabs or boards. The knives act
with a guillotine motion through the wood in the direction of the grain and not
end on along with it.
For the purpose of my invention, (which is represented on the annexed drawings,
Figures 1 and 2 being front and side elevations respectively, and Figure 3 a plan
of my improved combined wood sawing and slicing machine) I arrange any desired
number of saws A, A, horizontally and at distances apart in a slide frame B to
which they are secured by screw clamps C, C, at each end. The slide frame B is
actuated by a crank D from driving pulleys E, E, and moves in the frame F of
the machine.
At one end of the frame F I arrange two or more guillotine knives G, G, (of
which Figure 4 is a perspective view) adjustable in grooves H, H, in a slide frame I,
which moves in a projecting piece F of the frame F. The knives G, G, are
actuated by an eccentric or disc J (see Figure 2) driven by the pulleys K, K.
The two sets of pulleys E, E, and K, K, may be driven by the same, or different
engines as desired, and their shafts L, M, are preferably provided with fly
wheels N, N¹, as shown. The wood to be cut is fed into the boxes P, P, and passed
through the saws A, A, by the feed wheels Q, Q. The feed wheels Q, Q, are caused
to rotate by means of bevil gearing R, R, said bevil gearing R, R, being operated
by friction wheels S, S, and pawls T, T, from eccentrics U, U¹, on the shafts L,
and V. The shaft V is rotated by the speed cones W and W₁ at right angles
and connected by the band X, or equivalent reducing gear.
This feed mechanism may be actuated by the pulleys K, K, as shown on the
drawings, or by a belt on the speed cone Z from overhead shafting, or otherwise.
The wood under operation after passing through the saws A, A, is cut into the
desired lengths by the knives G, G, which are regulated to move at the right speed
for the purpose.
Several planks, or distinct blocks of wood are put into the machine in successive
order for the saws to act upon them in the direction of the grain, the knives
cutting also in the direction of the grain but transversely to that of the saws and
not from the end of the grain as in previous machines.

page_text: 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 improved construction and arrangement of machinery shown in the annexed
drawings and its method of action by which wood can be sawn and sliced in the
direction of the grain as herein before described.

Agent for the said C. F. Parsons.
