Dr. Fritz Mackensen in Worpswede. Asparagus cutter.

Addendum to patent 361464.

Patented in the German Empire on November 22, 1921. Longest duration: June 8, 1936.

The subject of patent 361464 is an asparagus cutter with a rotating knife and ring-shaped guide for the asparagus, which is guided by a narrow ring, 5 above which the knife is adapted to the ring shape, completely protected.

The present invention is an improvement on this asparagus cutter, according to which not only easy dismantling of the device for cleaning, but- ' which also makes the knife easy to replace. In addition, the Asparagus cutter even further in terms of preventing damage to the asparagus perfected.

As with the asparagus cutter according to the main patent, it is used to guide the asparagus a narrow ring, above which the knife, adapted to the ring shape, is completely protected lies.

The new invention is that the upper handle for the insertion rod is removable and holds the spring in the tensioned position, while after removing the The handle's spring, knife tube and knife sleeve can be pulled off the insertion rod can.

Another new feature is that the knife tube consists of two parts, which are connected by a claw coupling and Couplings are coupled together.

Another innovation is that the handle is made of the insertion rod two halves held together by screws, between which the spring end is jammed.

The invention is illustrated in the drawing in one embodiment, namely shows

Fig. 2 shows a side view of Fig. 1, also partially in section;

Fig. 3 shows in section the coupling of the actuating tube and knife sleeve;

Fig. 5 shows a section along line II of Fig. 4;

Fig. 6 shows a section along line H-II of Fig. 4;

Fig. 7 shows a section along line III-III of Fig. 4.

The asparagus cutter consists of the insertion rod a, which is provided at the lower end with the fixed asparagus guide ring b. This guide ring can either be soldered on or riveted and is expediently placed on a remote end of the insertion rod α . This guide ring is made narrow and, as can be seen from Fig. 5 to 7, tapers conically in the side elevation. It is designed to taper at all points after its lower edge on the inner surface. Above the guide ring is the sickle-shaped knife c, which is equipped with a longer,

fixed guide sleeve d is connected and pushed onto the insertion rod α. Below the knife, the guide ring b has a parabolic cross-section (see Fig. 5 to 7), while the width and height of the ring are determined by the width of the knife and the conical shape of the inner wall at the various points of the ring. The side of the ring b, towards which the ίο knife is turned, is kept as weak as possible. In general, the ring has a design at all points so that the resistance when it is led down into the ground is reduced to the lowest possible level and damage to the asparagus is excluded. The sickle-shaped knife c is guided on the rod α through the guide sleeve d in such a way that corners or twisting cannot occur when turning, and that the point rests on the upper edge of the ring when turning.

In the rest position, the knife, as seen from below, is completed by the guide ring covered. For this purpose, the guide ring protrudes beyond the knife on the inner periphery, so that the cutting edge is in the rest position completely .protected. After the knife has been swiveled completely, it towers above it the ring as little as possible. The shape of the ring and the sickle shape of the knife can do more or be chosen to be less oval.

In the rest position, the knife is placed against a stop e , which is chosen to be as small as possible and has a triangular cross-section in order to prevent the jamming of earth and other objects. The stop also tapers into the ring. A well-fitting tube f for the knife is pushed over the insertion rod α. This tube / is provided with a fixed handle g at the top and has a socket h which is expediently soldered on or otherwise held at the lower end. Both the knife tube and the knife sleeve d have a claw-like cutout i and possibly also several claws. After the knife tube / has been pushed on, there is a coupling between the knife sleeve d and the knife tube under the sleeve h . A spring k is pushed onto the insertion rod α above the handle g , the lower end of which is attached to the handle g , while the upper handle I for the insertion rod is detachably attached, for example consists of two halves I, I _{1 held} together by screws m , between which the spring end η is pinched. After putting on the handle I and turning the same ¹ , the spring is tensioned and closed in its! held compressed position, while after removing the handle k, knife ^; tube f and knife sleeve d, together with knife c , can be pushed upwards from the insertion rod.

The handling of the device is such that, with pressure on the handle I, the asparagus cutter is inserted as deeply into the earth as one wishes to cut the asparagus, the asparagus sliding into the guide ring 1.

By fixed or movably mounted indicia 0 the desired penetration depth is determined If the ring is inserted with the blade deep enough, one rotates the handle against the spring action, resulting in a pivoting of the blade and cutting of the asparagus has the consequence. As a result of the peculiar design of the guide ring and the position of the knife, damage to the asparagus cannot occur even if the guide ring is inserted inconsistently. After releasing the handle g , the knife returns to its position. You can then lift the cut asparagus end out of the earth when you pull up the asparagus cutter.

The knife can also be designed in a ring shape. If the counter-pressure is too strong, perhaps because a foreign body has gotten between the knife and the ring, the coupling can be designed to be easy to release. For this purpose, for example, the coupling can be effected by means of claws which are tapered. The spring h pushes the clutch back into its working position.
