All devices are mounted on the foundation α .

At bb the foundation α screwed carriers _x is the band saw performed in a conventional construction, and on addition to the carrier b nor the milling device, wherein, as shown. Figure 2 shows, the spindle f ₃ of the slidable in its axis direction of shaft d by the friction wheels ff _{x is} operated.

The shift of the shaft d, which respectively by moving the lever y _& to the right. happens to the left, has the purpose that the two friction wheels ff _x alternately brought into connection with the friction wheel f ₂ on the milling spindle f ₃ and thereby the latter can be rotated to the right and left as desired.

The milling cutter h is to be attached to the mandrel H ₁ , which is inserted into the hollow spindle f _s and tightened by the wedge h ₂ , above the table c. The milling spindle f _s can be moved slightly up and down in its axial direction by turning the screw g together with its bearings, so that the milling cutter h can either be raised slightly from the table c and the object to be milled can be placed on a disk below the milling cutter , or, as shown in Fig. 1 and 2, the milling cutter h can be set slightly recessed in the table c and works without the contact disc.

The mentioned milling device and band saw jointly have the work table c. When working with the cutter, the band saw is removed and when working with the band saw, the mandrel h _{x is} removed from the spindle f _z with cutter h .

The band saw is operated directly from the rotating main shaft r, in that the rotation is transmitted from there to the saw disk axis U ₁ by belts by means of disks r _x and r ₂ , and the milling device is operated from axis Ci ₁ by means of belts by means of disks r ₃ r ₄ on the axis d and by means of friction wheels ff _x and f ₂ on the milling spindle / _Ά .

The planing machine is located between the beams b _x b ₂ , resting on the screws i and guided in the beams b _x b _2; by turning the screws i from the nut J ₂ attached to the foundation α and into the same, high or. arranged to be movable deep, and next to the planing machine is in the carrier b. ₂ and the vertical knife shaft n _{5 is} stored in the block g ₂ above it, for the purpose of milling columns with it.

On the foundation α _{Ί of} the planing machine the length of the slide a _ß and on this the table k and k _} are arranged movable in the same direction. In Fig. 1 and 3, the two tables k and Zc ₁ are moved away from each other and between them there is interchangeable on the carriage a _{% of} the carrier C ₁ in connection with the bracket g ₂ for attaching the column, which by means of the knife shaft K ₅ should be milled. This carrier c _x must be able to work with the planer,

be released from the carriage a _a and removed.

Devices are also connected to the planing machine for dressing wood of thicknesses and widths, to be able to plan and fillet, as well as to drill long holes in wood and the long holes edgy to stofsen resp. to transform into rectangular.

In order to dress wood on the planing machine, the table k is still especially by pushing the wedges Z located under it against each other respectively. opposite by means of screw m a little high resp. deeply movable.

This movement of the table k makes it possible to set it back in front of the knife shaft η according to the thickness which, in order to dress the lower surface of an object, has to be planed from the same.

The device for planing thick wood or wood of the same thickness includes the attachment of a second knife shaft W ₁ together with transport _{rollers ο O 1} above the table Ar _{1 of} the planing machine. In order to plan thick pieces of wood with the aid of this device, the whole planing machine must be transported up against the upper knife shaft W ₁ so that the thickness of the wood to be planed is equal to the shortest distance between the table Zf ₁ and the knife shaft JJ ₁ .

The planing machine is transported up by rotating the vertical shaft jr _} either directly by handwheel O ₂ or indirectly by handwheel O _{3 by} means of shaft j / " _{4 of} the conical wheels pp _n, the shaft j> ₀ and the conical wheels p ₃ p _t is and from shaft Jr ₁ by means of the attached gear χ and the change gear X ₁ the wheels X ^ x ₃ with nuts z ₂ , whereby the screws i from the nuts i held by the foundation α are moved up.

In order to be able to set the table Zf ₁ to the necessary height after the knives screwed onto the knife shaft η , it is the same as the table k. by moving wedges located below it / arranged a little high and low adjustable.

The device for planing wood of the same width consists in the installation of the two vertical shafts qq _Y with cutter heads W ₃ W ₂ , of which the shaft q with cutter head H ₃ can be adjusted so that the distance between the shafts q and q _{t is} changed and can therefore be planed in different widths.

As shown in FIGS. 1 and 4, the knife shaft η is driven by belts by means of pulleys s S ₁ from axis J ₂ and the latter by belts by means of pulleys s ₃ S ₄ from the main shaft r.

As shown in FIGS. 1 and 3, the _{knife shaft W 1} is driven directly from the main shaft r by belts by means of pulleys t f.

The two vertically arranged cutter heads n., 77.J are, as Fig. 4 shows, by means of belts by means of disks t, ?. _s , as well as t _i f _{5 driven} from axis S ₂ and the transport rollers _{0 O 1 driven} from axis r by belts by means of pulleys f _{( .f 7} and by wheels Li ₁ hhh ^and h-

The wood to be processed is on the

Table k placed at the angle k. ₂ sliding, pushed over the knife shaft w and thus dressed on the lower side. When the wood is pushed further on the table Zc ₁ , it is first grasped by the grooved transport roller 0, passed under the knife W ₁ and conveyed on by the smooth transport _{roller O 1} , the upper side of the wood being planed and given the same thickness will.

Finally, the wood on the table Ar ₁ is transported between the two rotating, vertically arranged cutter heads W ₂ W ₃ and planed to a width, being pressed against the table k ₁ by the two rollers g _{s attached to levers and loaded by weight} . Thus the wood comes out at the end of the table Ar ₁ , worked on all four sides.

The so-called Chip breaker H ₁ ensures that the shavings do not fall onto the transport roller, but are thrown outwards.

1, 3 and 4 show, the thicknesser is _{fastened above the table Ar 1} on rails 11 and is arranged in such a way that, when it is put into operation, it is released from the rails u and transported on the extension of the latter Runs to completely expose the table Ar, above, for grooving and drilling wood.

The device for grooving wood on the planing machine or being able to drill into the same elongated holes consists in the hollow axis g- _n in which either the cutter head W ₄ for grooving or the drill is fastened in a similar manner by means of a wedge and cone.
