Abstract: A feeler gage mounting system comprising a case having a pair of opposed walls, a pin having an elongated pin body having opposed first and second ends, the first end being non-rotatably affixed to one of the walls of the case. The second end of the pin is connected to the other case wall. A plurality of feeler gage blade members are removably rotatably connected at two circular holes to the pin body. The pin body forms a key and the blade members form keyway sheets leading to the circular holes, the keyway slots being adapted to receive the pin body so that the blade members can be mounted onto or removed from the pin body at a particular angle at which the key of the pin body is positioned.

Abstract: An improved fuse removing apparatus including an elongated housing, a pair of complementary jaws extending generally longitudinally outwardly from the housing for engagement with a fuse. The complementary jaws are secured within the housing in longitudinal sliding relationship such that a plate at the end of the housing forces the jaws towards each other when the complementary jaws are urged into the housing. A cap disposed over the plate causes the jaws to rotate during use so as to lockingly engage the plate and thereby firmly grip a fuse without having to manually rotate the housing. All that is necessary to lock the device onto the fuse is to simply push the apparatus onto the exposed part of a fuse. A minimum of manual rotation is all that is required to disengage the jaws from the locking plate, and thereby release the retained fuse.

Abstract: A multi-function tester includes a hollow elongate cylindrical case having a longitudinal axis. A probe needle is fixedly mounted along the axis at one end of the case. A retractable protective sheath is provided which selectively covers and exposes the tip of the probe needle. A transparent cartridge containing electrical circuitry for performing a predetermined number of electrical tests is removably receivable within the case, with a penlite type battery being interposed between the cartridge and the probe needle. A compression spring is interposed between the battery conductive outer case and the probe needle. Electrical contacts connected to the circuitry within the cartridge are in electrical engagement with both the battery conductive outer case as well as to the center or positive terminal of the battery.
