Definitions

  • the patent is intended for a spirit level for measuring the incline on surface levels.
  • This invention solves a technical problem in the following way: the spirit level is constructed in such a way that when put in the desired position it enables us to read the angle of the incline in degrees on the visible angle scale.
  • the problem is solved in two different ways in terms of measure ⁇ ment. They differ according to the quantity of liquid in the container which is built in the casing of the spirit level.
  • picture 1 a tubular transparent container of circular shape filled with spirit exactly to haalf the level of the container, firmly built in the casing of the spirit level
  • picture 2 a flat transparent container of circular shape filled with spirit exactly to half the level of the container, firmly built in the casing of the spirit level.
  • the spirit level for measuring inclines on surface levels consists of the casing 5, angle scale 4, transparent container walls 1, spirit 2 and the empty part of the container 3.
  • the transparent container is filled with spirit 2 exactly to the half the level of the container, closed with a hermetic seal and firmly built in the casing 5.
  • the casing is best to be of rectan ⁇ gular shape, made of wood, metal or artificial material. It can be of a different shape but one of the two longest sides has to be straight and flat.
  • the angle scale has to be marked on the edge of the hollow of the spirit on the casing 5.
  • the angle scale may also be marked on the spirit container.
  • picture 1 a tubular transparent container of circular shape filled with spirit to the top so that only a small air bubble can be seen at the top.
  • the container is firmly built in the casing of the spirit level
  • picture 2 a flat transparent container of circular shape filled with spirit to the top so that only a small air bubble can be seen at the top.
  • the container is firmly built in the casing of the spirit level.
  • the spirit level for measuring surface level inclines consists of the casing 5, angle scale 3, transparent container walls 1, spirit 2 and the empty part of the container or air bubble 3. In both cases the transparent container is filled with the spirit 2 in such a manner that only a small air bubble 3 remains at the top of the container.
  • the container is closed with a hermetic seal and firmly built in the casing of the spirit level 5.
  • the casing is preferaably of a rectangular shape, made of wood, metal or artificial materials. It can be some other shape but one of the two longer sides has to be straight and flat.
  • the angle scale 4 is marked on the casing 5, next to the edge of the hollow fot the spirit 2.
  • the angle scale may be marked also on the spirit container.
  • the air bubble 3 which is visible in the trans ⁇ parent container has to reach the point on the scale 4 which marks 0 degrees. If the incline of the casing 5 is changed, according to the invention, the air bubble 3 reaches some other point on the angle scale 4 and on that point the angle or the incline can be read in degrees.

Abstract

La nivelle pour la mesure de pentes du sol résout le problème posé par la simple lecture de différentes pentes sur certaines surfaces, sur l'échelle d'angles (4) divisée en degrés qui figure sur le récipient circulaire et transparent. La lecture de la valeur de la pente s'effectue en degrés, au niveau du point où le niveau de la bulle d'air atteint un certain point sur l'échelle, avec une déviation négligeable.
