Remote indicator attachment kit
First Claim
1. A remote indicator attachment kit for use with a mechanical level gauge of an oil tank located in the basement area of a dwelling to indicate, to the dwelling'"'"'s occupant who is located at a remote point from said tank, that the oil level in the tank has dropped below a predetermined value, said level gauge having a see-through housing an a vertically movable indicator member in said housing, comprising in combination:
- a) a permanent magnet adapted to be fixed onto the movable indicator member of said mechanical level gauge to move therewith,b) a reed switch actuatable by said permanent magnet when brought near the magnet,c) clamp means for adjustably mounting said reed switch on the see-through housing of the mechanical level gauge for adjustment to different levels thereon,d) an electrically actuatable indicator for installation at said remote point,e) energizable electric means cooperable with said reed switch and said electrically actuatable indicator, to activate the latter when the reed switch is actuated by said permanent magnet, andf) an attachment member having means for gripping said indicator member and having positioning means engageable with the magnet.

Abstract
A remote indicator attachment kit for use with the mechanical level gauge of an oil tank located in the basement area of a dwelling, to indicate at a remote point the drop in oil level, comprises a magnet attachable to the movable member of the existing mechanical gauge, and a reed switch and mounting that is attachable to the see-through housing of the mechanical gauge, to be influenced by the magnet on the movable member. Circuitry connected to the reed switch and to the remote indicator is energized to provide an indication at the remote point.
