Wood wool machine.

Patented in the German Empire on October 14, 1887.

The present invention relates to a wood wool planing machine in which pieces of wood any length can be processed.

The characteristic of the machine consists in the following facilities:

Above the horizontally moved back and forth, the knife-carrying slide are two displaceable Stand attached, in which the clamping jaws used to clamp the wood can be raised and lowered by vertically mounted screw spindles. The ends of the screw spindles carry wheels with are connected to a control mechanism, by virtue of which between the Jaws clamped pieces of wood before each hanging of the slide, automatically and with jerks is employed against the latter.

Effects a peculiar device when the piece of wood arrives in that position in which it is not processed is more possible, an automatic lifting of the jig.

In the drawing is a wood wool planing machine constructed in accordance with the present invention shown, namely:

Fig. Ι a front view, partially in section, Fig. 2 is a plan view,

3 shows a cross section along x-x, FIG. 1.

Fig. 4 shows the locking mechanism for moving the piece of wood.

Fig. 5 is a vertical section through the displaceable clamping jaw along the line w-w, Fig. 6, and

Fig. 6 is a horizontal section according to \ - \, Fig. 5;

Figure 7 is a side view of the front stand.

As can be seen from FIGS. 1 to 3, on the table A ₁ on which the slide B carrying the knives slides, two stands C C ¹ are arranged, which slide by screws c, FIG. 3, the heads of which slide in the grooves α, be held. If the screws are lifted, the stand can be moved as desired and clamped by tightening the screws at any point along the length of the wood.

The uprights are provided with vertical straight guides, in which the moved by screw spindles D D ¹ C ¹ C blocks. ² slide up and down. The latter carry the two clamping jaws c ³ c ⁴ , of which the former is firmly ^{screwed to one block c 1} , while the other c ⁴ can be moved in the second block c ^{2 by} means of a lever c ^5, FIGS. 5 and 6 This lever c ⁵ is mounted in two lugs c ^{6 of} the block c ² , engages with its lower end c ⁷ in a slot in the clamping jaw c ⁴ and carries a weight c ^s at its upper end. If it assumes the fully extended position in FIG. 1, the clamping jaw is withdrawn. If, on the other hand, it is turned in the direction of the arrow so that it assumes the position shown in dotted lines, the movable clamping jaw c * is advanced and the weight applies it to the wood.

The two screws DD ₁ have bevel gears dd ^{1 of the} same size at their upper ends , which are coupled by the wheels e β _λ sitting on the common shaft E. Of the latter, the wheel e ^{1 is} displaceable on the shaft E and carries a sliding wedge which engages in a groove e ^{2 of} the shaft E so that the wheels e ¹ and ^{d 1} remain in engagement and always both when the stand C ¹ is moved Screws are rotated uniformly. This turning of the screws DD ¹ is effected by the main drive shaft F.

This is namely provided with an eccentric / whose rod is connected to a two-armed lever f ¹ .

The latter carries a pin / ² which is adjustable in a slot and on which there is a pull rod f ^B which is connected to an arm g ¹ which is loosely attached to the hub of the wheel g · ² and provided with a pawl g , FIG. 4. The pawl g engages with the ratchet g ² and rotates the same at each return movement of the carriage B. the ratchet g ^"1 sitting as well as the Riemscheibe g ^s loosely on the shaft g, onto which the. in the wheel d engaging bevel gear g ^e, Fig. 2 and 3, is attached.

A dog clutch g · ⁴ , which can be disengaged by the lever g ⁵ , FIG. 3, rotatable about g ^{9, is arranged between the two wheels.} If the clutch is moved to the left, as shown in Fig. 3, the ratchet wheel g " ^{2 is} connected to the shaft G and the screws DD ¹ are rotated and evenly rotated by the gears g ^e ee ¹ and d ¹ when the carriage B slides backwards the piece of wood jerks down against the knife. The lever g ⁵ is held in this position by the lever H, the end of which is supported against the pin g ^{s. '} If, however, this lever H is turned by pressing down the handle h (when a new piece of wood is to be clamped), the spring g ⁷ pulls the arm g ^B to the right and connects the coupling g ^A with the pulley g ³ , which from the main drive shaft is driven in the opposite direction as the ratchet wheel g ^2. As a result, the screws DD ^{1 are turned} back and the blocks c ^l c ² lifted. This also happens automatically when they have reached their lowest level by the block c ² pushes the lever h ¹ and by means of the rod / i ² turns the lever H.

On the shaft G there is a brake disk 7, FIGS. 3 and 7, which prevents the wheel g · ² from being rotated back when the pawl g swings back. The brake band i placed around the same is attached to a lever i ^l and is tensioned by the spring i ^2. i ³ is an angle lever provided with a handle i ⁴ , the second arm f ⁵ of which presses on the lever i ^1. The same is connected to the arm g ⁵ by the rod i ⁶ . So if the latter is moved to the right (to turn back the screws), the lever i ^{s is} turned at the same time; the arm i ⁵ presses on the lever i ¹ and relieves the brake band i.

If the lever i ^{a is} pushed back again by means of the handle i ⁴ , the coupling g * is also shifted (whereby the pin g ^% enters the notch of the lever H ) and the direction of movement of the screws DD ^{1 is} reversed.

In order to enable the carriage to move quickly without warming up, the arrangement is that the carriage B engages over the bed and the sliding surfaces of this carriage are continuously covered with oil. For this purpose, strips j, FIG. 3, and the raised side walls j ^{1 are} attached to the two inner sides of the slide track J. The gullies created in this way are closed at both ends by screwed-on plates j ² and filled with oil, j ³ are metal strips that cover these oil vessels so that the oil is not contaminated by dust and wood chips Plates B ¹ B ^{2 is} extended to and fro by a steering rod k which does not engage directly on the slide, but on a rod A ¹ which is fastened to the slide by means of a pivot k ² and is guided at k ^h. The knives are attached to the slide directly or by means of their own knife box L, FIGS. 1 and 2, and consist of the scoring knives Z and the planing knife P, which work in a known manner.

Claims (3)

Patent claim: A wood wool machine, characterized by the simultaneous presence of the following facilities: 1. Vertical stand CC ¹ above the horizontally to and fro, the knife-carrying slide, in which stands c ³ c ⁴ carried by screw spindles DD ¹ are movable, whereby one of the main . drive shaft F in function locking g ^% brings the screw spindles in jerks in rotation so that the clamping jaws are lowered and the wood clamped between these jaws is placed against the knife. 2. To lift the clamping jaws, an automatically acting and also manually adjustable reversing device for the screw spindles DD ¹ , consisting of a coupling g *, which from the clamping jaw c ^{4 reached} in the lowest position through a Lever mechanism g · ⁶ ti ² ii ^e H is changed over, so that a constantly rotating disk g ³ connects to the drive shaft G of the screw spindles and reverses the direction of rotation of the screw spindles.
3. A support guide J, which is provided with two lateral strips j and j ¹ , so that a chamber is formed which is closed by the end plates β and filled with oil, into which the extensions of the slide B which laterally overlap the guide j preventing the machine from warming up. 1 sheet of drawings.
