Company H. Hauptner, 5650 Solingen, Kuller Str. 38-44 Shearing machine for animals, especially cattle and horses

The invention relates to a shearing machine for animals, in particular cattle and horses, with a lower comb that is fixed to the shearing head and an upper comb that can be moved back and forth by a motor drive. In known embodiments, both the lower comb and the upper comb are held on the shearing head by an adjusting screw. The tension between the lower comb and the upper comb is regulated by tightening or loosening the adjusting screw. It often happens that the tension is set either too tight or too loose. If the tension is too tight, the friction between the lower comb and the upper comb causes the shearing combs to heat up and wear out prematurely. If the tension between the lower comb and the upper comb is set too loosely, the cut animal hair is clamped between the shearing combs, often blocking the back and forth movement of the upper comb. This can damage both the shearing combs and the drive motor.

The invention is based on the task of eliminating the defects identified and of creating a shearing machine of the generic type in which manual regulation of the tension required between the shearing combs is not necessary. To solve this problem, it is proposed according to the invention that the tension between

the lower comb and the upper comb that works together with it can be regulated by a spring pressure plate that is detachably provided on the shearing head. This design has the advantage that the tension between the shearing combs specified by the manufacturer of the shearing machine is automatically adjusted when the spring pressure plate is attached, so that further manual regulation is not necessary.

In a preferred embodiment of the invention, the spring pressure plate can be made of hardened, tempered steel, have a concavely curved surface and be equipped with receptacles for the fastening elements at the highest points of its surface. This ensures that when the fastening elements are inserted, the curved spring pressure plate is deformed in such a way that the spring pressure plate, which strives to spring back to its original position, exerts a pressure between the shearing combs with the prescribed tension. The bending of the spring pressure plate is selected so that the desired tension between the shearing combs is achieved.

According to a further feature of the invention, the receptacles for the fastening elements can be located on the center line of the spring pressure plate. This is therefore recommended in order to load the fastening elements of the spring pressure plate evenly.

The arms of the spring pressure plate, which are advantageously located on both sides next to the center line, can preferably be designed parabolically and have different radii of curvature. This is useful for manufacturing reasons.

The edges of the arms can consist of edge zones that are ground on both sides. This ensures that when replacing the shearing combs by loosening the spring pressure plate, the operator's hands cannot be injured by sharp edges.

The fastening elements of the spring pressure plate can advantageously be designed as retaining screws.

The invention is shown in an embodiment in the drawing. It shows:

Fig. 1 is a bottom view of the shaving head,

Fig. 2 a side view of the shaving head,

Fig. 3 an external view of the spring pressure plate,

Fig. 4 a side view of the spring pressure plate,

Fig. 5 is an enlarged section of the left edge zone of Figure 4, and

Fig. 6 an internal view of the spring pressure plate.

Figures 1 and 2 show the removed shaving head of a commercially available clipper. This consists of an electric motor (not shown), the housing of which is designed as the handle of the clipper. The lower comb 11, the front edge 12 of which is equipped with a large number of cutting teeth 13, has, as Figure 1 in particular illustrates, openings 15 in its rear area 14, through which anchor members 16 adapted to the openings 15, which are located on the underside of the shaving head 10, pass.

and secure the lower comb 11 in its working position. The upper comb 17 is operatively connected to the lower comb 11 arranged below it and is also provided with cutting teeth on its front side.

The upper comb 17 is moved back and forth over the lower comb 11 via a driver 18 by the electric motor (not shown). The captured hair of the animal to be sheared is thereby cut off.

As Figure 2 shows, both the lower comb 11 and the upper comb 17 are held by a spring pressure plate 19, which is attached to the underside of the shaving head 10 with retaining screws 20.

The spring pressure plate 19 is shown in Figures 3, 4, 5 and 6. It is made of hardened and tempered steel and is bent to form a concave surface 21. The spring pressure plate 19 is provided with receptacles 23, 24 at the highest points of its surface 21, which is crossed by a center line 22, which engage the retaining screws 20, as shown in Figure 2. The arms 25, 26 of the spring pressure plate 19, which lie on either side of the center line 22, are parabolic in shape. Their radii of curvature are different, with arm 26 having the larger radius of curvature. The edges 27 of the arms 25, 26 are ground on both sides, as can be seen in Figure 5.

The shearing combs 11, 17 can be easily replaced. This is done by removing one retaining screw and loosening the second retaining screw 20. The spring pressure plate 19 can then be pivoted so that the shearing combs 11, 17 can be pulled out downwards.

As already mentioned, the embodiment shown is only an example of the implementation of the invention. It is not limited to this. Various modifications and designs are possible. For example, the spring pressure plate 19 could have a different shape and be more curved.
