between the two plates holds them apart and retracts thefingers into the tube.With the bottom plate grasped between the fingersand enough thumb pressure applied to the top plate tocompress the spring, the tool fingers extend from thetube in a grasping position. When the thumb pressure isreleased, the tool fingers retract into the tube as far asthe object they hold will allow. Thus, enough pressureis applied on the object to hold it securely. Somemechanical fingers have a flexible end on the tube topermit their use in close quarters or around obstructions(fig. 1-75).NOTEThe fingers are made of thin sheet metal orspring wire and can be easily damaged byoverloading.REVIEW QUESTIONSQ42.What are mechanical fingers used for?FLASHLIGHTLEARNING OBJECTIVES: Identify thetype of flashlight that belongs in every toolbox.Each toolbox should have a standard Navyvaporproof two-cell flashlight. The flashlight is usedconstantly during all phases of maintenance. Installedin both ends of the flashlight are rubber seals, whichkeep out all vapors. The flashlight should be inspectedperiodically for these seals, the spare bulb, and coloredfilters, which are contained in the cap.NOTEDo not throw away the filters; they will benecessary during night operations.REVIEW QUESTIONQ43.Identify the type of flashlight that belongs inevery toolbox.INSPECTION MIRRORLEARNING OBJECTIVES: Describe theuse of inspection mirrors.Several types of inspection mirrors are available foruse in maintenance. The mirror is issued in a variety ofsizes and may be round or rectangular. The mirror isconnected to the end of a rod and may be fixed oradjustable (fig. 1-76).The inspection mirror aids in making detailedinspections where the human eye cannot directly seethe inspection area. By angling the mirror, and with theaid of a flashlight, it is possible to inspect most requiredareas. One model of inspection mirror features abuilt-in light to aid in viewing those dark places whereuse of a flashlight is not convenient.1-47Figure 1-76.—Adjustable inspection mirror.Figure 1-75.—Mechanical fingers.
