Abstract
A hand-held tool for forming a rivet head at the plain end of a rivet includes an elongated handle having an elongated internal cavity with a guide wall surface extending to an adjacent guide wall surface in an insert having an end wall. The end wall is provided with a predetermined thickness and contains an aperture to house a shop head formed on the plain head of a rivet. An inertia block is slidably guided by the guide wall surfaces of the handle and insert for reciprocation between a displaced position remote from the end wall and a position for contact with the end wall. A spring located in the elongated handle urges the inertia block against an end of a rivet when protruding from the aperture in the end wall and arrests recoiling movement of the inertia block after impact with a rivet end in a direction away from the end wall.
Claims6
A hand-held tool for forming a shop head on a plain end of a rivet, said hand-held tool including:
- an elongated handle having an elongated continuous internal cavity terminating at internal threaded end portions with a guide surface adjacent an end wall defined by a cup shaped insert with an upstanding threaded side wall engaged with one of said internal threaded end portions, said threaded side wall terminating at a planar wall which is coplanar with a terminal end of said elongated handle, said end wall having a predetermined thickness to establish a predetermined shop head thickness and containing an aperture having a predetermined diameter to house a volume of rivet material upset to form a shop head;
- an inertia block slidably guided by said internal guide surface for reciprocation between a displaced position remote from said end wall and a position for contact with said end wall;
- and
- a resilient member supported by said elongated handle for urging said inertia block against an end of a rivet when protruding from said aperture and arresting recoiling movement of said inertia block after impact with a rivet end in a direction away from said end wall.
A hand-held tool for forming a shop head on a plain end of a rivet, said hand-held tool including:
- an elongated handle having a continuous internal cavity closed at one end by an end wall and by a cap at the end opposite thereto, said internal cavity having a guide surface adjacent said end wall, said end wall having a predetermined thickness and containing an aperture to house a shop head when formed from a plain end of a rivet, said elongated handle including internal threaded end portions each terminating an end of said continuous internal cavity, said end wall comprising a cup shaped insert having a threaded surface for mating engagement with one of said threaded end portions, and wherein said cap is further defined by a threaded plug portion extending from a handle extension for threaded engagement with the other of said threaded end portions;
- an inertia block slidably guided by said internal guide surface for reciprocation between a displaced position remote from said end wall and a position for contact with said end wall;
- and
- a spring located in said internal cavity between said inertia block and said cap for urging said inertia block against an end of a rivet when protruding from said aperture and arresting recoiling movement of said inertia block after impact with a rivet end in a direction away from said end wall.
