Abstract
A feed assembly for a foot-pedal operated riveter and a method of using the same is disclosed. The feed assembly includes a rivet stop that has a tip that separates a lowermost fastener from a second from lowermost fastener when the riveter is in a non-operational position. This rivet stop prevents fasteners from sliding down a raceway on the feed assembly. When the riveter is moved into an operational position, the rivet stop moves out of the way and permits the second from lowermost fastener to slide into position for subsequent installation. The rivet stop thus enables automatic reloading of the riveter during operation.
Claims28
A feed assembly for a riveter comprising:
- a tumbler defining a cavity therein;
- a raceway extending downwardly from the tumbler;
- wherein said raceway defines a feedslot therein;
- and wherein the feedslot which is adapted to receive fasteners one at a time from the tumbler;
- a pair of opposed resilient spring arms;
- wherein a first end of each of the spring arms is fixedly secured to the raceway remote from the tumbler;
- a guide block provided on a second end of each spring arm;
- a channel defined between the guide blocks, the channel being adapted to receive a lowermost fastener from the raceway therein;
- wherein the channel is adapted to selectively receive a plunger from the riveter therethrough and when the plunger passes through the channel the guide blocks move laterally away from each other and the second ends of the spring arms flex outwardly away from each other;
- wherein the plunger contacts the lowermost fastener and moves the lowermost fastener through the channel and out of the raceway;
- and
- a rivet stop provided on one of the spring arms or on one of the guide blocks;
- wherein a section of said rivet stop projects across the feedslot of the raceway and is adapted to selectively contact a second from lowermost fastener and prevent movement of the second from lowermost fastener along the feedslot and into the channel.

A riveter comprising:
- a base adapted to rest on a floor surface;
- a post extending upwardly from the base and defining a cavity therein;
- a head defining a cavity therein;
- wherein the head of the riveter is mounted on the post a distance from the base;
- a foot pedal extending outwardly and forwardly from the post;
- a plunger mounted for reciprocal movement within the head;
- and
- a linkage assembly engaged with the foot pedal and the plunger;
- wherein a portion of the linkage assembly is retained within the cavity of the post;
- and another portion of the linkage assembly is retained within the cavity of the head;
- wherein lever arms of the linkage assembly pivot entirely within the cavities of the post and head of the riveter;
- and wherein movement of the foot pedal in a first direction causes the linkage assembly to move the plunger within the head in a first manner;
- and movement of the foot pedal in a second direction causes the linkage assembly to move the plunger within the head in a second manner;
- and
- a feed assembly, wherein the feed assembly comprises:
- a tumbler defining a cavity therein;
- a raceway extending downwardly from the tumbler;
- wherein said raceway defines a feedslot therein;
- and wherein the feedslot is adapted to receive fasteners one at a time from the tumbler;
- a pair of opposed spring arms;
- wherein a first end of each of the spring arms is fixedly secured to the raceway remote from the tumbler;
- a guide block provided on a second end of each spring arm;
- a channel defined between the guide blocks, the channel being adapted to receive a lowermost fastener from the raceway therein;
- the plunger selectively passes through the channel and moves the guide blocks laterally away from each other and the second ends of the spring arms flex outwardly away from each other;
- and wherein the plunger is adapted to contact the lowermost fastener and move the lowermost fastener through the channel and out of the raceway;
- and
- a rivet stop provided on one of the spring arms or one of the guide blocks;
- wherein a section of said rivet stop projects across the feedslot of the raceway and is adapted to selectively contact a second from lowermost fastener and prevent movement of the second from lowermost fastener along the feedslot and into the channel.
