Abstract
A simple and compact tool for use with aircraft spark plugs to reset the spark gap, which enables a person to hold the spark plug to the tool, hold a gauge to the spark plug, and squeeze the electrodes of the spark plug to set the gap, all under field conditions. The tool includes a pair of bars pivotally connected at one end and a nut fixed to a first of the bars to loosely hold a spark plug, the nut having a cut-away portion to permit the second bar to move over a spark plug held by the nut, and the second bar having a recessed edge which can move against an electrode of the spark plug to bend it.
Claims5
A tool for resetting the gap of an aircraft-type spark plug, comprising:
- a pair of bars having pivot ends pivotally connected together and having opposite handle ends;
- and
- a spark plug-holding member with a threaded hole, mounted on a first of said elongated members at a location spaced from the pivot end thereof by less than half the length of said first member;
- the second of said bars having a recess positioned so that when said bars are pivoted together, the recess on said second bar moves over the threaded hole of said spark plug-holding member, whereby a person can hold and operate the tool with one hand, with the spark plug held on the tool, while this other hand holds a spark gap gauge device.
A tool for resetting the gap of an aircraft-type spark plug comprising:
- first and second pivotally connected bars having handles that can be moved together and apart;
- a nut member threaded to receive the threaded head of an aircraft-type spark plug, said nut member fixed to the underside of said first bar;
- said second bar lying immediately under said first bar and said nut member being cut away along the top portion thereof which is in the path of said second bar.
