PATENT LETTERING

CLASS 7: Sheet metal and wire production.

Addition to patent no. 30752 of December 4, 1883.

Date of death in the German Empire on October 6, 1885. Longest duration: December 3, 1898.

With the sharp curvature which the wire undergoes in the guide piece F due to the chisel m and the bead w , it suffers a not inconsiderable friction which makes it more difficult to guide it, and the bead n> a strong wear, which latter circumstance results in that the setting of the chisel m to the bead w for a certain wire dimension soon no longer corresponds to the circumstances. In order to counteract these inconveniences, the bead w is made rotatable, as can be seen in the drawing, and the fulcrum is at the point where the wide curve of the guide piece merges into the sharp bend or further back. This also makes it possible to replace the bead w when it is worn and in this way to keep the main part of the guide piece usable.

As long as the wire to be circulated has not yet been taken up by the second pair of rollers, the bead w is maintained by a spring s in the position shown in FIGS. 2 and 3 of the accompanying drawings, corresponding to FIGS. 1 and 2 of the main patent. But as soon as the wire has been taken up BEZW by the second pair of rollers. has emerged from the same, the spring is released by a lever device to be set up according to the respective conditions and the bead is thrown around by the pressure of the wire, so that it assumes the position indicated by dotted lines in Fig. 2. The time of wear of the chisel in and of the bead w is hereby restricted to a minimum. The spring 5 is preferably triggered automatically, in that the wire acts on the lever device connected to the spring when it emerges from the second pair of rollers, but can be provided by a worker at a suitable moment. After the wire has left the guide piece, the bead piece is brought back into its initial position. This can also be done automatically by attaching a spring or weight, but it is preferable to have a worker do this work.

With regard to the overall arrangement of the bypass device, it should be noted that the guide piece F BEZW. F _{1 of} the main patent no. 30752 can also be carried out in the manner indicated by FIG. 4 of the accompanying drawing, ie can be extended to both sides so far that the use of the tubes R and R ₁ provided in the main patent is omitted.

The bypass device can also take place in the manner indicated by FIG. 5 of the accompanying drawing. Here, as in the main patent, the device consists of three parts: the inlet duct Fe, which is widened in the shape of a funnel at the front and at the other

At the end, the twisting of the wire is effected by means of the sharp bend achieved by the chisel m and bead w , the outlet guide Fa and the intermediate piece \, which is connected in a suitable manner to the other two pieces. The shape of the intermediate piece corresponds to the guide piece F ₁ or the guide piece F of the main patent, can also bezw. be used in greater or lesser length.
