Anobject of thisinventionisto provide a .n spirit V"level which is adjustable' in aA mounting tovarious anglesV tothe 4horizontal so' that the' a, housing, which vhousing is "adjustable "tov any desiredl angle within a" predetermined range;

"A :further object of thisy invention' is jto providel a 'spirit level' construction whichY outwardly bears' .the ,appearance of "a conventional level, but vwhichhas mounted within the housing, means operable from the exterior bywhich the level within the housngmay bepartially rotated to a selected angle. i y

The above and various other objects and advantages of .this invention'will in part be' described in and in'partbe understood from the followingdetailed description of the present pre,-

The inner side ofy this clamping member 19 also operates to'maintain the cylindrical housing member 14 concentrically of the bezel 18. A level adjusting means, generally designated 50 as 25, is mounted foroperation exteriorly of the' bezel 18,'and` comprises a bolt or operating member'26 having a pinion or gear 27 secured thereon against rotation and positioned for engage- -ment with the gears or rack 16 carried by the S5,

' nut 28 carried by the shaft 26 may be suitably tightenedso as to prevent ready turning of this In the present instance, this operating member 25 is constructed in the form of a screw having the head flush With the bezel 18 and the kerf of the` screw positioned for engagement with a screw driverjor the like, so that the'o'peratingigl member Y25 may be yturned so as to partially rotate the cylindrical level carrying housing 14 and adjust this level L to any desired angle. Preferably, the .cylindrical housing 0r member 14 is provided with an inwardly yextending pin or indicating arm v29, and the bezel 18 has gradua-4 vtions 30v on the exterior thereof,-these gradualo f right angles to the member 11, or if desiredonly one member may be mounted in-the Vbar 10,1

this member being swingable in an areY of sub-V stantially 90? lso that the adjacent faces' of the bar maybe positioned in a horizontal position with Athe level L also positioned horizontally.

When the level L is parallel with the opposite sides of thebarl, it can be used asa convene tional leveling means.: ,When itis desired'to use the structure herein disclosed forfdetermining various anglesffrom the. horizontal so'thatV in the construction ofya building or the like, the
