SBEGIFIGATION forming part of Letters Patent No. 731,587, dated June 23, 1903. Application filed December 11, 1902. Serial No. 134,824 (No model.)

To all rah/omit may concern,- Be it known that I, ROBERT K. MARPLE, re-

' sidingatPhiladelphia, in the county or Philadelphiaand State of Pennsylvania, have invented certain new and useful Improvements in Staple-Machines, of which the following is a specification.

This invention relates to mechanism adapted for cutting blanks, forming them into staples, and driving and riveting'such staples. It has as its primary object to'produce a simplified machine for effecting these operations and to render the parts readily changeable in order to adapt the mechanism to the character of the work The nature and characteristic features of the improvements will more fully appear by vil 3, the latter being preferably movable to vary its height with reference to the stem. A cam wheel or disk 4t is journaled on the arbor 4', supported by the frame, and has the cam-grooves 5 and 6 formed in the face thereof. The groove 5 operates the plunger 7 bymeans ofits engagement with the roller 8 on the plunger. This plunger is adapted to reciprocate in the stem 2 and has fixed thereon astop9, which moves in the recess 9', formed inthe stem, and limits the upward movement of the plunger with relation to the stem aswell as its downward movement with relatiou'to.thediethereon. The die 10 is sleeved on the lower end of the plunger 7 and is movably engaged therewith by a screw 10, which passes through the die and projects into a blind channel 7, formed in the plunf. gerl A die 11, coacting with the die 10, is;

sleeved on the pin 12 and lies within the socket 13 of the arm 14, the die 11 being cushioned upon the spring 15, located in the socket. A knifel6 is attached to the socket and is adapted to coact with the edge of the die 10 in shearing blanks from a metallic ribbon 23 fed between the dies. The cutting mechanism may he modified, however, by omitting the knife 16 and attaching a knife 17 to the lower die, so as to project above the same and coact with the edge of the upper die in cutting the blanks, the spring 15 being provided with sufficient resistance to effect the cutting operations. A rod 18, fixed to the arm 14, is adapted to reciprocate in a bearing 19 on the stem, the rod having therein a worm or cam-groove 20, which receives a pin or boss 21, fixed in the bearing. An arm or hearing 22, to which the rod 18 is revolubly connected and longitudinally fixed, carries a roller 23, which engages the cam-groove 6, the arm being engaged by the stem 2 to prevent the roller leaving the groove.

It will be understood that when the revolving cams 5 and 6 elevate the parts '7 and 18 a metallic ribbon 23, fed by any suitable mechanism between the dies 10 and 11, will bepressed by the die 11 against the die 10 and out by the knife 16or 17. The blank thus shorn and held between the dies is by the further revolution of the cam-disk 4 and the consequent further upward movement of the rod 18 forced into the hollow die 10 against the end of the plunger 7 by the forming-pin 12, the thrust of the stem 2 and the die 1 0,supported thereby, against the die 11 compressing the spring 15 and permitting the forming-pin to enter the upper die and form the rivet 21. The further revolution of the cam-disk moves the rod 18 downward,and by the engagement of the worm 20 with the pin 21 the arm 14: swings the mechanism carried thereby out of the path of reciprocation of the plunger mechanism comprising the plunger 7 and the die 10, upon which this plunger mechanism is carried down until the die 10 strikes the work supported upon the anvil 3 and the plunger 7 drives the staple 24.

As the parts are of simple construction and readily changed, the mechanism may be varied readily as required for different kinds of work. By changing the cam-disk and providing cam-grooves of various forms the strokes of the reciprocating parts may be varied at will, the anvil being adjustable to accommodate its height to the stroke. There is thus provided simple and flexible mech- IOO anisln permitting operation in angles and corners of boxes or receptacles of various forms and depths.

Having described my invention, I claim 1. In a machine of the class described, the combination with a support of reciprocating mechanism comprising a plunger and a die movably sleeved thereon, a second recipro' eating mechanism comprising a pin and a die movably sleeved thereon, and means for operating said .mechanisms, substantially as specified.

3. In a machine of the class described, the combination with a support of reciprocating mechanism comprising a plunger and a die movably sleeved thereon, a second reciprocating mechanism comprising a knife, a pin and a die mova'bly sleeved on said pin, and means for operating said mechanisms, substantially as specified.

4. In a machine of the class described, the combination with asupport of a reciprocating mechanism comprising a plunger and a die, means for operating said reciprocating mechanism,a second reciprocating mechanism comprising a knife, a pin'and a die, and means for swinging said second reciprocating mechanism out of the path of said first reciprocating mechanism, substantially as specified.

5. In a machine of the class described, a cam, a reciprocating plunger operated by said cam, a die sleeved on said plunger and having a limited movement thereon, in combination with a forming-pin, shearing mechanism, and means for supporting'said parts, substantially as specified.

6. In a machine of the class described, a cam, a forming-pin connected therewith and reciprocated thereby, in combination with a die adapted to receive said pin, a plunger movable in relation to said die, and a cam for operating said plunger, said cams being rigidly connected, substantially as specified.
