Rebate cover cavity.

Patent addition to No. 24564 of March 10, 1883.

Patented in the German Empire on May 17, 1884. Longest duration: March 9, 1898.

The covering surface h of the brick protected in the main patent lies on the upper side of the covered brick; Since this surface is rough due to the cutting with the wire, it can happen that the precipitation (rainwater) does not run off completely in the first time after the roofing because of the roughness and that something seeps through.

In order to avoid this inconvenience, I press the midrib e downwards into a plane with the main ligament b c; I also get another useful replacement of the leaflet section h if I take the rough covering surface hj on the lower covering side of the tile.

The attached drawing shows:

Fig. Ι the schematic overlap type my previous roof tile (P. R. No. 24564), Fig. 2 the tile cross-section,

3, 4, 7 and 8 the schematic type of covering of the bricks with the rough covering, covering surface H ₁ downwards, namely sections according to, 4-SCD, EF and GH and parallel-perspective view,

5, 6, 9 and 10 show the schematic type of covering of the tile with the central rib depressed at the top, namely sections according to JKL, MN and OP and a parallel perspective view.

These latter figures show that the top view of the brick is exactly the same as that of the main patent is identical, which is of course because the part in question is in a plastic state of pressing pressed down in one case, cut away at the top in the other case became.

The area h ₂ therefore corresponds exactly to that h of the main patent; the difference and advantage lies solely in the circumstances, has undergone That the thickness of the brick strip at point of respective no weakening, but BEZW the thickness of the midrib e ni. also retained the main band b or c. The modification of Figs. 3, 4, 7 and 8 does not have the same appearance as the brick of the main patent, but the schematic Figs. 1 and 3 immediately show a great deal of correspondence, in that the constructive difference is only in the choice of the material used covered or the covering part of the tiles lying on top of each other. While in the main patent (see also Fig. 1) the upper part was cut from the central rib e to form the surface h , in the construction Fig. 3, 4, 7 and 8 to form the recess Zz ₁ cut the lower part from the middle band b . The overlap area h of the main patent is actually taken down here and no longer available up; for the latter reason the original midrib e is no longer there

necessary, but it could be placed in alignment bc , like m in that of the surface L The two modifications of the brick of the main patent described here are made with the same mouthpiece construction for friction compensation as the brick of the main patent; while in the modification Fig. 5, 6, 9 and io the upper part of the central rib e to form the surface h. _{2 is} pressed down into the middle band through the die and counter die, the cutout / J _{1 of} the modification Fig. 3, 4, 7 and 8 is most simply made by hand, instead of using a wire from the cutting table, after using the otherwise shaped brick the board has been taken from the second or tiltable roller carriage. In both of the additional modifications described here, the side folds g remain with the rib elevations d and f as in the main patent. '

Claims (1)

Patent Claims: i. In the case of the patent no. 24564, claim 1., protected extruded interlocking tile with two raised lateral rib folds and raised central rib, the variant that the surface h respectively. /? ₂ , instead of a wire cut as before, is now achieved by pressing down the central rib e into the plane of the central band bc by means of a die and counter die, which are guided against one another, also for the purpose of producing a flat covering surface, FIGS. 5, 6, 9 and 10.
2. The cutout Zi ₁ created with wire cut on a strand interlocking tile with a flat main band and two raised lateral rib folds, so that instead of a wire cut h on the upper side _{, the strand interlocking tile has a wire cut Zi 1} on the lower side on the middle or main band b , which enables that two bricks following upwards cover the lower bricks in such a way that the interlocking rib folds of the lower bricks are covered by the cutouts Ix _{1 at the} top, instead of the same as in the case of the main patent no. 24564 the lateral rib folds, ie cover the surface h formed with the cutting wire, in the variant FIGS. 3, 4, 7 and 8 the rib folds are covered _{by the cut out surface Zj 1.} For this purpose ι sheet of drawings.
