Abstract:
In a nut installation head having a nut passage receiving a plurality of nuts in side by side relation, a transverse plunger passage communicating with said nut passage, a plunger reciprocating in said plunger passage to install a nut received in said plunger passage, a reciprocal feed for feeding a nut successively into said plunger passage, said head having an apertured nose with said plunger passage extending through said nose and said nut passage extending into said nose and said plunger moving through said nose. The improvement comprises a nut guide for said head, including a cylindrical slot formed in said nose, parallel to and displaced laterally of said plunger passage. A resilient retainer is nested within said slot having an upright recess. A hardened steel dowel of cylindrical shape is positioned within said slot and laterally and guidably nested partly within the retainer recess with a portion of the dowel extending into the plunger passage to guidably support a nut therein. Successive downward movement of the plunger moving said nut along said dowel is adapted to forcefully project the nut into piercing and interlocking registry with a panel underlying said nose, said dowel guidably engaging said nut during its downward movements.
