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.

The feed assembly as defined in claim 2, wherein the rivet stop is located on the raceway between the tumbler and the guide blocks; and the rivet stop is adapted to prevent downward movement of the second from lowermost fastener when the spring arms are spaced the second distance from each other; and the rivet stop does not prevent downward movement of the second from lowermost fastener when the spring arms are spaced the first distance from each other. 4. The feed assembly as defined in claim 3, wherein the rivet stop is substantially J-shaped. 5. The feed assembly as defined in claim 4, wherein the J-shaped rivet stop includes a shaft and a head, and the head has a curved outermost edge, and the outermost edge is adapted to contact a head of the second from lowermost fastener when the spring arms are disposed the second distance from each other. 6. The feed assembly as defined in claim 5, wherein the head of the rivet stop further includes a V-shaped tip adapted to be positioned between the lowermost fastener and the second from lowermost fastener when the spring arms are disposed the second distance from each other. 7. The feed assembly as defined in claim 6, wherein the shaft includes a first side edge and a second side edge, and the tip of the head extends for a distance outwardly beyond the second side edge of the shaft. 8. The feed assembly as defined in claim 7, wherein the tip includes a shoulder edge disposed generally at right angles to the second side edge of the shaft. 9. The feed assembly as defined in claim 8, wherein the curved outer edge of the head intersects the shoulder edge at an acute angle. 10. The feed assembly as defined in claim 9, wherein the acute angle is approximately 45 degrees. 11. The feed assembly as defined in claim 10, wherein the shaft of the rivet stop includes a first section that is substantially vertically disposed, and a second section extending outwardly from one end of the first section at an angle; and the head of the rivet stop extends outwardly from an end of the second section remote from the first section. 12. The feed assembly as defined in claim 11, wherein the angle is from about 133 degrees up to about 137 degrees relative to the first section. 13. The feed assembly as defined in claim 12, wherein the head is coplanar with the second section. 14. The feed assembly as defined in claim 1, further comprising: a feed chute defining an opening therein that is in communication with the cavity of the tumbler; wherein the feed chute is adapted to feed a plurality of fasteners through the opening and into the cavity of the tumbler. 15. 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; anda 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; anda 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; anda 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. 16.
