Claims
- 1. In a motor-driven fastener machine having a base, an anvil on the base, a fastener driving mechanism mounted for movement relative to the base, the improving comprising
- drive-control means also mounted on the base about pivot means for movement with respect to the base to cause the fastener driving mechanism to drive the fastener against the anvil;
- rotary drive means mounted on the drive-control means such rotary drive means including eccentric means carrying shaft means;
- follower arm means mounted between (1) the base about a second pivot means spaced from the first pivot means, and (2) the rotary drive means such arm means including eyelet means for surrounding and engaging the eccentric means;
- transmission means (66,63) connected to the rotary drive means (68) for causing the drive-control means (50) carrying such shaft means (62) to move through a cycle of movement including a reciprocating path (A); and
- fastener mechanism means (55) on the drive-control means (50) slidably engageable with the fastener driving mechanism (17, 43) which engagement means (55) causes at times the fastener mechanism (I7, 43) to be driven downwardly and at other times causes the drive-control means to move the fastener mechanism upwardly.
- 2. The fastener machine of claim 1 in which the rotary drive means includes a driven wheel and having in addition dumbbell means comprising in turn (1) such means secured to the driven wheel and (2) two spaced apart cylindrical elements secured in an offset manner to the shaft means and further having follower arm dumbbell engaging means which is a circular recessed opening for receiving one of the cylindrical elements whereby rotation of the driven wheel carries the circular elements around such shaft in an eccentric pattern.
- 3. The fastener machine of claim 1 in which the fastener driving mechanism includes a head workpiece compensation means which includes spring means which is compressible between the workpiece and the engagement means on the driving and control means.
- 4. The stapler machine of claim 1 in which the transmission means comprises a motor-driven shaft and spur gear which spur gear is engageable with the driven wheel and shaft means.
- 5. The motor-driven fastener machine of claim 1 in which the anvil is in turn mounted on an anvil plate means which plate means is pivotally mounted on the base for pivoting from an open to a close position and having further first cam means on the anvil late means and cooperating second cam means on the driving and control means to cause such plate means to pivot.
- 6. In a motor-driven staple machine having a base, an anvil on the base, a staple forming and driving mechanism pivotal on the base, the improvement comprising
- drive-control unit means mounted on the base about a first pivot means for causing the stapler forming and driving mechanism to form and drive the stapler against the anvil;
- rotary drive means mounted on the drive-control unit means such rotary drive means including dumbbell means carrying shaft means mounted on the drive-control unit means;
- follower arm means mounted between (1) the base about a second pivot means spaced from the first pivot means, and (2) the rotary drive means, such arm means including dumbbell engaging means;
- transmission means connected to the rotary drive means for causing the drive-control unit means to carry such shaft means to move pivotally through a cycle of movement including a reciprocating arcuate path; and
- slot channel means on the drive-control unit means slidably engageable with the staple mechanism which slot channel means causes at times the staple mechanism to drive the stapler mechanism downwardly and further at other times causes the driving and control means to move the staple mechanism upwardly.
- 7. The staple mechanism of claim 6 in which the rotary drive means includes a driven wheel and having in addition a dumbbell unit comprising in turn (1) shaft means secured to the wheel and (2) two spaced apart cylindrical elements secured in an offset manner to the shaft means and in which the follower arm dumbbell carrying means is a circular recessed opening for receiving one of the circular elements whereby rotation of the driven wheel carries the cylindrical elements around such shaft in an eccentric pattern.
- 8. The stapler machine of claim 6 in which the stapler driving mechanism includes a head workpiece compensation means which includes spring means which is compressible between the workpiece and the slot means on the drive-control unit.
- 9. The stapler machine of claim 6 having battery means for powering the motor driven shaft.
- 10. The stapler machine of claim 6 in which slot channel means is substantially horizontal in its upper position and below horizontal in its down position.
