Title: Improved apparatus for testing sparking plugs
IPC: H01T13/58
Filed: 1944-10-27
Abstract: 576,080. Sparking - plug testing machines. LODGE PLUGS, Ltd., and HOPPS, B. Oct. 27, 1944, No. 20927. [Class 7 (iv)] A sparking-plug testing machine comprises a fluid actuated piston by means of which a sparking plug is held in position during test with the sparking end in open communication with the fluid acting on the piston and means for connecting the plug to a high tension circuit. The operative connection between the sparking plug A and the piston 4 is by means of rods 11 which pass through a block 9 containing a cylinder 5 in which the piston works and a slidable member 10 and spring pressed plunger 16 which bears on the plug. The plunger serves both to hold the plug in place and connect it to a source of high tension current. When the pressure is supplied to the cylinder the piston is raised and carries with it rods 11 and member 10 and this raises the plug and forces the sparking end against a seating 18 so that it is in communication with the interior of the cylinder 5. A container for liquid on a carrier 20 can be raised to immerse the plug and indicate leakage. The carrier is slidably mounted on a column 3 of the machine. The block 9 is mounted at the top of the column 3 and at its rear carries a lamp chamber for illuminating the plugs while immersed. The light passes through holes in the column and a window in the head. The sparking can be viewed by means of a transparent window 35 at the top of the cylinder and a mirror 34. A mirror 41 is also provided for viewing the back of the plug while under test. An ignition coil 39 may be mounted on the block 9 and an adjustable spark gap 36 may be provided in the H.T. lead. The H.T. current passes to the plunger 16 by terminal 14, cable 13 and terminals 12, 15. A vent hole 40 in the member 10 enables air which may leak from a faulty plug to escape into the liquid container. A release valve 42 enables the plug to be removed by releasing the pressure in the cylinder so that the member 10 can fall under its own weight.
