Abstract
A combination tool includes a compact “D” shaped handle and a rotating drum for tool selection. The straight back segment of the “D” provides an axis for rotation of the drum. The drum includes opposed tool ends, either of which may be rotated into position for use. In a preferred embodiment, the tool ends are keys for releasing a tamper resistant cap over a Schrader valve. Each key is shaped for a cap used with a particular Freon® refrigerant used in an air conditioning unit. The drum includes indicia of which Freon® refrigerant the corresponding key matches.
Claims15
A combination tool comprising:
- a drum;
- two opposing tools attached to the drum and sharing a tool axis;
- a drum axis approximately centered between the tools and approximately orthogonal to the tool axis;
- a ring handle cooperating with the drum axis wherein the drum may be rotated about the drum axis to position one of the tools for use.

A combination tool comprising:
- a tool carrier;
- a first key attached to the tool carrier, the first key shaped to cooperate with a first locking cap;
- a second key attached to an opposite end of the tool carrier and sharing a key axis, the second key shaped to cooperate with a second locking cap;
- a tool carrier axis approximately centered between the keys and approximately orthogonal to the tool axis;
- a ring handle cooperating with the tool carrier axis wherein the tool carrier may be rotated about the tool carrier axis to position one of the keys for use.

A combination tool comprising:
- a tool carrier;
- a first key attached to the tool carrier, the first key shaped to cooperate with a first locking cap configured to reside on a Schrader valve used to add and remove a first Freon® refrigerant from an air conditioning unit;
- a second key attached to an opposite end of the tool carrier and sharing a key axis, the second key shaped to cooperate with a second locking cap configured to reside on the Schrader valve used to add and remove a second Freon® refrigerant from an air conditioning unit;
- a tool carrier axis approximately centered between the keys and approximately orthogonal to the tool axis;
- a handle cooperating with the tool carrier axis wherein the tool carrier may be rotated about the tool carrier axis to position one of the keys for use, wherein the handle includes indicia of the Freon® refrigerant which each key corresponds to.
