ZOBEL NEUBERT & CO. in SCHMALKALDEN. Cork cutting machine.

Patented in the German Empire on July 31, 1877. Longest duration: February 22, 1892.

The purpose of the machine is to use as much as possible from the cork wood, which has been pre-cut in the form of a cube Protection of the expensive cork wood, stopper in cylindrical or conical shape to cut.

The operation that is carried out automatically by the machine is one of the most meticulous Study of the hitherto customary handicraft, in which the cork cube at is pushed past a sharp, fixed knife in a spiral.

The machine has two cast iron feet to which a cast iron frame piece q is screwed on the side. On this frame, a support piece h can be moved up and down between two vertically standing, dovetail-shaped undersized guide strips, which carries the knife s intended for cutting, and that is clamped between planed surfaces by screws. A cast iron / ground guide rail i provided with guide strips is also fastened horizontally on top of the frame piece g. A hand support k is pushed back and forth on the same when the worker is cutting cork.

A small bearing / is screwed laterally to this frame g , in the bore of which there is a double nut thread with a very high pitch (380 mm). The long screw spindle m, which has the same high-pitched thread, moves in this nut thread. In order to produce these screw spindles, which cannot be produced on an ordinary lathe, a special tool device had to be made.

The spindle »? is firmly supported by one, front end, which can be held between attachment disks, in a small bearing arm η extending laterally on the hand support k and at the end in front of the bearing arm carries a small disk o with needle points. Opposite this disk is a second, needle-tipped disk O ₁ attached to a short piece of rotatable spindle /. This spindle is also jn a small, laterally interpretative arm bearing rotatably q.

The disk O ₁ can be approached to the disk ο. The piece of cork wood intended for cutting is picked up by these discs.

At the beginning of a cut, the worker standing in front of the forehead of the machine pulls the hand support k towards him until the latter hits the adjustable rubber buffer W ₁ (i.e. to the right in the front view, sheet 1). For this purpose, the two parts of the booklet r and T _{1 are} grasped by hand and the disks 0 O ₁ provided with the needle points are opened involuntarily by means of the handle T _1. The cork cube is then placed between the discs in such a way that one of its side faces rests on the almost horizontal knife, the edge of which is almost exactly below the. The center of the spindle m and p is located, the spring /, being pushed to the side.

If the worker pushes the support k forward by 380 mm by horizontal pressure against the handle r , the cork cube has covered this distance at the sharp edge of the knife and at the same time made a rotation through the action of the screw m. The result is a round cork, which ο during retraction of the support and the opening of the discs by the spring f _t is thrown out. The path of the hand support k is also limited on the other side by an adjustable rubber buffer u.

Placing a cube on the knife requires an exactly tangential cut of the same, so that the greatest possible savings are made with regard to the material, if the cubes are evenly prepared.

The bearing arm η is connected to a plate which, for longer or shorter plugs, can be moved between horizontal , ground strips cast on k and can be fixed by means of the screw It _1. - On the same plate there are two twisted bolts standing horizontally, which carry movable and adjustable crossheads y and ) \. In the latter, upright, small spindles are stored, each of which has a small emery roll attached to it so that it can rotate. The larger of the same X ₁ , which exactly brushes the lower knife surface with its ring surface, is used to re-sharpen the knife every time. The smaller, finer-grained one.

Claims (3)

which brushes the surface of the knife at an angle, is used for finishing the any degree, so that in this way the knife is always kept sharp, and a cut of the most perfect smoothness is achieved. The emery rolls are adjustable by means of Spirals pressed against the knife and turned into rotating when the support is pushed back and forth Movement. The small bearing arm q can be shifted in a similar way between vertical strips on k and locked by the screw ^ ₁ , whereby the cutting of conical corks is effected. The adjustability for the different thicknesses of the plug is achieved by raising and lowering the knife support h by means of the toothed racks ζ ζ attached to h , the gear α α by the shaft b , which is provided with a square shoulder at the end, by using a wrench is rotated accordingly. On this shaft by a clamping screw, a c with the shaft to be connected to lever c, the lower end of a stirrup depends d has. - When working, the cork cutter stands at the front end of the machine shown in sheet II with the right tip of the foot in the stirrup d. The slightest turn of the foot to the left brings about a lifting of the knife and in this way allows the worker to position the knife at any moment so that a weaker one is made from the finished cork as soon as the cork wood shows defects on the surface. From this description the following peculiarities of the construction are evident:
ι. The round cut is made when the cork cube, placed on the knife, makes a helical movement on a fixed knife. This Einrichtimg a quick insertion and an economical work with regard to the material is required. 2. The knife is kept constantly sharp by a peculiar sharpening apparatus. 3. The easy adjustability of the knife allows the worker at any moment Reworking the cut cork, and the adjustability of the clamping discs that Cutting of corks of all practical dimensions, both cylindrical and conical.
