makes four cuts.

Patented in the German Empire on September 19, 1906.

The subject of the present invention is a hair clipper of the type in which there is a fourfold cutting action, with each going back and forth of the hand lever with the assistance of an intermediate lever, two oppositely directed Cuts are made. The invention consists essentially in one of the following device described in more detail, according to which the first and fourth cut of the machine by direct action of the hand lever on the movable cutting blade and the second and third cut by action the intermediate lever moved by the hand lever is brought about onto the cutting blade.

The accompanying drawing shows the clipper in
Fig. I in section.

Figs. 2 to 4 show the movable cutting blade in front and end views at three various taken during the first and fourth cutting process, by the Nose of the movable handle lever brought about positions compared to the on fixed cutting blade seated fastening pin.

Fig. 5 shows the fixed cutting blade in front and end views.

6 shows the articulated lever arranged within the housing cap.

Fig. 7 shows the upper part of the movable handle lever in front and side views and

Fig. 8 the upper part of the fixed handle hebeis in front, side and top view on a slightly larger scale.

α is that as usual with the fixed handle lever s respectively. with the housing cap c formed on the same by bolts d and fastening screw e with the interposition of a resilient washer / connected lower cutting blade, which receives its firm hold on the housing cap that the latter with an upper shoulder g and a lower pin h (Fig. 1 and 8) engages in corresponding recesses 1, 2 (Fig. 5) of the cutting blade. Within the housing cap c, with its cutting prongs protruding from the same, the upper movable cutting blade b is also slidably mounted on the fixed cutting blade α in the usual way, whereby it is through a groove r provided on it, in which the housing cap c of the lever s with a Rib t (Fig. 8) engages, is guided straight in the horizontal direction.

In the movable cutting blade b (Fig. 2) recesses 3, 4 and 5 are provided with a corresponding shape. The screwed into the fixed cutting blade α passes through the recess 3 as a fulcrum for a small one

Claims (2)

two-armed articulated lever k (Fig. 6) serving pin / through. The lever k has at both ends directed .Vorsprünge i, j, of which the projection i temporarily engages in a recess η provided in the upper arm of the movable lever m (Fig. 7) and the lower projection j in the Recess 4 of the movable cutting blade b engages. The lever m is also provided with a nose ο which extends into the recess 5 of the movable cutting blade. The operation of the device is as follows:. In the case of the partial resp. half pressing against each other of the handles of the two levers m, s is the movable cutting blade b respectively by the lever m. through the nose ο of the same, which engages the right-hand boundary edge of the downward continuing part of the recess 5 of this cutting blade (indicated by dashed lines in Fig. 2), from which in Fig. 2 opposite the pin /, d of the fixed cutting blade α assumed Moved position to the right, here brought into the positions according to FIGS. 3 and 4 and thus completes the first cut. With the subsequent second half-pressure or the termination of the pressing of the lever handles against one another, the movable cutting blade b is moved back into its previous position by means of the small two-armed lever k, in that the upper arm of the lever k is pushed through the upper jaw w des which engages with the projection i thereof Hand lever m is pressed to the right, while his lower arm swings to the left with the protrusion j engaging in the recess 4 of the sheet b; the second cut is made here. It should be noted that the backward movement of the cutting blade b is not hindered by the nose ο of the lever m, since the sheet with the horizontal part of its recess 5 can slide back on this nose ο. Now the normally arranged spring ρ comes into action, which was compressed when the levers m, s were pressed against one another. When the handle levers are pressed apart by this spring, the upper arm of the hand lever m moves the small lever k, which has meanwhile come into engagement with the recess η of the latter with its projection i, around its pin / in such a way that its lower arm with the projection j moves to the right moves, whereby he also pushes the cutting blade b to the right and the third cut is made. During the further apart movement of the handle lever m, s by the spring _p, the upper arm of the lever swings further and further to the left and its right jaw q (FIG. 7) gradually disengages from the projection i of the lever k respectively. passes under him, the movement of the cutting blade b is interrupted to the right and BEZW in the movement to the left. converted into the fourth cut in that now the nose 0 of the upper arm of the lever m hits the left-hand boundary edge of the downwardly extending part of the recess 5 of the cutting blade b and pushes it to the left; the small lever k remains inactive. The movable cutting blade b and the nose 0 of the hand lever m are now again in the original shown by FIG. 2; original position, and the four cutting processes start over. Godfather nt-A ν Proverbs: 1.Hair clipper with a movable cutting blade which is slidably arranged on a fixed cutting blade and which makes four cuts with each back and forth movement of the hand lever by making the first and fourth cuts by direct action of the hand lever on the movable cutting blade and the second and third cuts by action an intermediate lever operated by the hand lever is brought about on the cutting blade, characterized in that the movable cutting blade (b) with each stroke of the hand lever fm) alternately by the movable hand lever fm), which with its nose (ο) into a recess (5) of the Cutting blade (b) engages and executes in the same on the one hand a movement causing the advance of the cutting blade (b) and on the other hand an empty sliding movement in the same, as well as by the two-armed lever engaging with a projection fjj in a recess (4) of the cutting blade (b) fk) is moved, which at der'in the recess (5) of the movable n the cutting blade taking place empty sliding movement of the nose (0) of the hand lever fm) comes into engagement with the latter and under the action of the same brings about the opposite movement of the movable cutting blade (b). 2. Embodiment of the hair clipper according to claim 1, characterized in that the movable hand lever fm) two different length attack jaws (n>, q) for the projection (i) of the lever fk) and a recess fn) loading in order to be able to effect the movement of the lever (k) in one direction by means of the longer jaw (n>) and the movement in the other direction by means of the jaw (q) and to enable the lever to move under your Swing the projection (i) of the lever (k) further and then move the movable scissor blade (b) in the opposite direction to the movement caused by the lever (k) by means of the nose (ο) .
