COMPLETE SPECIFICATION.
A Machine for Cutting Wood Blocks and Strips.
1, ADOLF GOGL of Szepes-Teplicz, in the Kingdom of Hungary and Austrian
Empire, Forest Official, 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 this invention is to provide a machine whereby blocks and strips
of wood can be cut at one stroke. This invention also enables the blocks and
strips of wood used in the manufacture of matches and match boxes to be produced
in a much simpler manner than heretofore.
And in order that my said invention may be properly understood I have
hereunto appended an explanatory sheet of drawings, whereon,
Fig. 1 is a perspective sectional view of the machine and,
Fig. 2 is a part front elevation of the drum.
The machine consists essentially of a rotating drum composed, as shown, in
section of four sectors of which those at opposite sides of the drum are alike.
The two sectors having the greater radius are provided with vertically cutting
rollers or knives d behind which are fitted planing blades c. The other two sectors
having the smaller radius are made with inclined guide grooves e, el cut in their
surfaces s. The cutting frame B is provided with a projection h which works in
the guides e and with a projection j which works in a groove in the table D. A
number of circular knives g (or in the case of very hard wood triangular or other
suitably shaped knives) are mounted on the frame B and are fed forward against
the wood being operated on. The cutting edges of the knives g are at the same
distance from the centre of rotation of the drum as the edges of the blades c.
The modus operandi is as follows
cutters g.
The wood to be operated on is placed on the table D and pressed against the
As the drum rotates the projection h is caught by the projection or
tooth (Fig. 2) at the side of the drum and as a consequence of the pressure
exerted in an oblique direction by one edge of the groove e on the projection / it
along with the frame B is caused to travel longitudinally from the left towards the
right hand side of the table whereby the wood is cut into in the direction of its fibres.
The action of the cutters is such that a number of longitudinal cuts, corresponding
to the number of cutters, are made in the wood. As the drum continues to revolve
the circular cutters d eventually come in contact with the wood and make vertical
cuts in it at determined distances apart and then the planing blades c cut off,
according to their adjustment, correspondingly thick layers or pieces of the wood.
These pieces fall down between the spokes of the drum, which are pitched or have
the form of a part of a screw thread, and are owing to the screw action
automatically delivered by the spokes.
The cutting frame, when it reaches the right hand side of the drum, is, as the
latter continues to revolve eventually caught by the projection r of the groove e¹
(at the opposite side) which is inclined in an opposite direction to the groove e,
and as a result the frame B is caused to travel back again from right to left.
The reciprocatory motion of the frame is repeated at each revolution of the
wheel.
When full width strips are to be cut off by the machine the cutting frame B is
merely thrown out of gear.

page_text: 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
consider novel and desire to claim is :-
1. A machine for catting wooden blocks and strips wherein the material being
operated upon is pressed against a rotating cutting drum and subjected to the action
of reciprocating and rotating circular cutters which cut the wood in the required
longitudinal and transverse directions, strips or pieces being subsequently cut from
the material by means of planing irons fixed to and rotating with the drum and
automatically delivered by the conveying screw action of the spokes, substantially
as hereinbefore described with reference to the drawings annexed.
2. The cutting frame B which is reciprocated by the action of the inclined
grooves e, e' of the rotating drum, substantially as hereinbefore described.
