Addendum to patent 275382.

Patented in the German Empire on February 10, 1914. Longest duration: July 4, 1927.

The object of the invention is to simplify and improve the closure disc according to the main patent 275382.

While according to that patent, the disc is studded on both sides with lugs, the the pressed material in the. Stroke channel openings in, is the disc according to the invention smooth both on the edges and on both sides, i.e. without any elevation or the like, but mounted at an angle on the drive shaft that it sways when turning Performs movements, similar to the well-known "swaying circular saw". By These fluctuating movements will affect the strand material when it penetrates with a large amount Speed rotating disc displaced laterally and streaked into the duct openings, whereby the closure of the hollow stone comes about.

The technical progress is partly in the simpler design of the subject of the invention compared to the disc according to the main patent, and partly in the possibility of being able to close even very thin-walled hollow stones without errors, which was only possible to a limited extent with the older disc. A further advance consists in the fact that it is not necessary to keep disks with different length, corresponding locking noses in stock for different channel cross-sections; rather, this need is met in the case of the disk according to the inventor 40

tion fulfilled by appropriate inclination of the same on the drive shaft. In economic Regard should be mentioned that the new locking disk compared to the older one, whose noses are exposed to wear and tear, completely is significantly superior in that it hardly causes a thirtieth part of the operating costs.

The drawing represents the subject of the invention on a longitudinal section through the brick strand in front view.

The smooth, round disc ι is adjustably mounted with an inclination 3-7 ⁰ as needed on the drive shaft. 2

Set in high rotation, it is guided against the brick strand 3, cuts it, closing the channels at the same time, to form shapes that are closed on all sides 4.

The closure is effected in that the strand material is removed from the penetrating disc moved in the same direction of rotation (carried away) and by the lateral fluctuations the same is deposited at the same time between the walls of the brick and spread there, whereby a similar Closure comes about.

During the experiments, the inventor claims to have observed how the molded product can be the number of lateral fluctuations of the disc necessary for closure correspond to the interface. The closure is fire-proof and is with the
