Type Element Assembly Apparatus

This apparatus automatically assembles and tests cap assemblies on type elements such as those used in SELECTRIC* typewriters. Each of these type elements, when assembled, comprise a spherical portion with embossed characters on its surface and a cap portion including a cap head cover, a cap cam lever, and a spring element.

In typical prior installations the type element caps are assembled on a machine and welded to the type element on another machine. Inspection and testing are done manually.

Referring to the drawing, the machine consists of a floor base 1 typically about 8 feet square which supports an indexing machine 2 with associated turret 3, tool mounting brackets 4, 5, and 6, and work stations 1-12. This type of construction lends itself to a minimum amount of disassembly and assembly, which is helpful when the machine is relocated. The functions of the mechanisms at the stations is as follows: Station 1 - A cap headcover for a type element is automatically fed, oriented and loaded to a workpiece holding fixture. Stations 2 and 3 - Idle. Station 4 - A cap cam lever is automatically fed, oriented and loaded to the cap headcover. Station 5 - The trunion pins on the cap headcover are automatically lubricated. Station 6 - A shaped spring element is automatically fed, oriented and loaded to the cap headcover. Station 7 - Idle. Station 8 - A type element is automatically fed, oriented and loaded to the headcover. Station 9 - The...
