Abstract
A fuel tank gauge having a pivotal measuring portion that can accurately measure fuel level in a fuel tank of a vehicle not on level terrain and which also may be installed in the tank fill-pipe at an angle with the tank whereby the gauge pivot permits the measuring portion of the gauge to be in vertical position at all times.
Claims2
A fuel tank gauge for accurately measuring fuel in a tank having a fill pipe through which said gauge is directed,
- said gauge including a gauge cap adapted to be attached to said fill-pipe,
- said gauge having a pair of support rods attached to said gauge cap and extending through said fill-pipe to the interior of said tank,
- said support rods having lower ends with a float guide freely pivotally connected thereto,
- said float guide having a rotatable vertical shaft with a spiral section having a vertically moveable float mounted on said spiral section,
- said float engageable with said float guide in a vertically moveable, non-rotational manner whereby vertical movement of said float causes said vertical shaft to rotate, and
- means on said filler-cap connected to said rotatable vertical shaft to indicate the rotational position of said shaft and thus the vertical position of said float.
