Description
Wasserwage. Die bisher gebräuchlichen Wasserwagen für Bauhandwerker, Zimmerleute usw. be stehen meistens aus Holz und sind zur Ver stärkung mit Eisenkanten und -platten an den beiden Enden der Auflegefläche versehen. Diese Verstärkungen haben aber keinen nennenswerten Einfluss auf die Genauigkeit und Haltbarkeit der Wasserwagen, da die Holzteile sich trotzdem stark abnützen, wäh rend die Eisenteile deformiert werden. Der artige ,Wagen werden deshalb bei etwas grober Behandlung rasch unbrauchbar.
Gegenstand der vorliegenden Erfindung ist eine Wasserwage, deren Auflegesohle mit einer teilweisen in das Holz eingelassenen, harten Leichtmetallschiene mit U-förmigem Profil abgedeckt ist, so dass ein Verziehen oder Abnutzen des Holzes nicht stattfinden kann.
Auf beiliegender Zeichnung sind zwei Ausführungsbeispiele des Erfindungsgegen standes dargestellt.
Fig. 1 zeigt die Ausführungsform in per spektivischer Darstellung, während Fig. 2 die Schiene einer zweiten Form veranschaulicht.
In das prismatische Holzstück a sind in bekannter Weise Libellen b hinter Glas scheiben<I>a</I> eingebaut. Eine starke Schiene<I>d</I> aus hartem Leichtmetall, vorzugsweise aus Anticorodal oder einer andern in bezug auf Härte, Korrosionswiderstand und geringe Deh nung hochwertigen Aluminiumlegierung, ist auf die Auflegeflächen a'angebracht, indem sie teilweise in das Holz eingelassen und gege benenfalls mit versenkten Holzschrauben be festigt ist. Das Profil der Schiene d ist U-förmig, wie dies aus der Zeichnung ohne weiteres ersichtlich ist.
Das Profil wird vor teilhaft gemäss Fig. 2 achwalbenschwanzartig sein, damit ein besserer Halt beziehungsweise Verankerung der Schiene, sowie eine ein wandfreie Versteifung des Holzstückes a erzielt wird.
Die Schiene d aus Anticorodal ist sehr widerstandsfähig und schützt somit die Sohle vor jeder Abnutzung oder Deformation, wäh rend die Wasserwage nicht sonderlich er- Schwert wird. Die Lebensdauer der Wasser wage ist durch die Anbringung der Schutz schiene also beträchtlich verlängert worden.
Spirit level. The previously common water wagons for builders, carpenters, etc. be mostly made of wood and are provided for reinforcement with iron edges and plates at the two ends of the support surface. However, these reinforcements have no significant influence on the accuracy and durability of the water car, as the wooden parts still wear out a lot, while the iron parts are deformed. Such wagons will quickly become unusable if handled roughly.
The subject of the present invention is a spirit level whose support sole is covered with a hard light metal rail with a U-shaped profile that is partially embedded in the wood, so that the wood cannot warp or wear.
In the accompanying drawing, two embodiments of the subject invention are shown.
Fig. 1 shows the embodiment in a perspective view, while Fig. 2 illustrates the rail of a second form.
In the prismatic piece of wood a, dragonflies b are installed behind glass panes <I> a </I> in a known manner. A strong rail <I> d </I> made of hard light metal, preferably made of anticorodal or another aluminum alloy of high quality in terms of hardness, corrosion resistance and low elongation, is attached to the support surfaces a 'by being partially embedded in the wood and if necessary, is fastened with countersunk wood screws. The profile of the rail d is U-shaped, as can be readily seen from the drawing.
The profile will be in the form of a swallowtail before some according to FIG. 2, so that a better hold or anchoring of the rail, as well as a wall-free stiffening of the piece of wood a is achieved.
The rail d made of Anticorodal is very robust and thus protects the sole from any wear and tear or deformation, while the spirit level is not particularly bad. The lifespan of the water dare has been extended considerably by attaching the protective rail.
