STAPLE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 731,630, dated June 23, 1903.

Applicationfiled March 1, 1902.

To all whom it may concern.-

Be it known that we, EDWARD A. SUVER- KROP and ROBERT COATES, residing in the city of Philadelphia, county of Philadelphia,

and State of Pennsylvania, have jointly invented certain new and usefulImprovements in Staple-Machines,of which the following is a specification.

i This invention relates to machines for forming and setting staples, as in the manufacture of paper boxes and leather goods, for example. Its chief objects are to provide in a single machine mechanism for cutting variously-shaped blanks, forming staples of various proportions therefrom suitable for va-' rious uses and settingthe staples so formed all in a continuous operation. The means employed to accomplish these objects permit the use of a metallic ribbon of uniform width,

from which staplesof various proportions can be formed. No waste of material is entailed, as no scrap is formed, all of the material being incorporated in the staples, which have a peculiar form, lending strength to the at- The mechanism of the staples at will.

The further objects and characteristic features of theimprovements will more fully appear in the following description, taken in connection with the accompanying drawings in illustration ofthe invention, of which- Figure 1 is a top plan view. Fig. 2 is a side elevation. Fig. 3 is a front elevation. Fig. 4. is a sectional View in illustration of the movable head, taken on the line 4 4 of Fig. 5. Fig. 5 is a sectionalview taken on the line 5 5 of Fig. 4. Fig. 6 is a sectional View taken on the line 6 6 of Fig. 4. Fig. 7 is a sectional viewshowing details of the striking mechanism. Fig. 8 is a perspective View showing the striking-die mechanism in relation with the blank and staple as formed and set. Fig." 9 is a perspective view of means for adjusting the cutting mechanism,

As illustrated in thedrawings, the frame 1 has a head 2, which guides a vertically-recip- Serial No. 96,199. (No model.)

rocating bar 3, operated by a lever 4, the lever being fulcrumed upon the frame-strut 5 and pivotally connected with the bar-head 6. The bar 3 has a die 7 movably connected therewith by means of a pin 8', which is fixed .in the die and movably seated in the slot 9 of the bar. A pin 10, pressed down by a spring 11, bears upon the pin 8 and thrusts the die .7 downwardly; but when the die is stopped in the downward movement of the rod 3 the striking or forming pin 3 has a further movement through the die, which is permitted by the play of the pin 8 in the slot 9 and the compression of the spring 11, caused by stopping the pin 10 in its downward movement with the rod 3. The die 7 has a shearing edge 7, which coacts with a shear 12, supported by the frame-arm 13, a guide 14: controlling the movement of a ribbon of metal 15, which is fed to the shears and out thereby into diamond-shaped blanks 16. The blank, which is cut by the descending die 7, is placed thereby upon one of a series of dies 17, each having a perforation 18, into which the striking-pin 3is adapted to force a blank againsta pin 19,which plays in the perforation. {Astaple or rivet 20 is formed thereby and has the long points 20 and the short points 20", the former penetrating and binding the materials together, while the latter bite the surface andhold the head thereto.

The several dies 17 are fixed in a ring or collar 21, which revolves upon a bearing-head 22, having a peripheral channel 23, in which the inner ends of the several pins 19 move. The collar 21 is rotated by means of ratchetteeth 2-ithereon,whichareengagedbyaspringpressed pawl 25, pivoted to a ring 26, loose on :the collar, the ring being pivotally connected with a link 27, having a pivotal connection 28with the reciprocating striking mechanism. By this mechanism the dies 17 are given a step-by-step motion, which carries them successively into registration with the die 7 and pin 3' and successively over theanvil or workholder 29, a spring-pressed pawl 30, riding upon the polygonal ring 31 on the collar, centering the dies. The head 22 is adapted to reciprocate in a guideway 32, supported by the frame, a spring 33, seated in the recess 10o the foot, and the foot being forced downward by the arm 42, fixed to the rod 3, in the path of which arm the head is located. The downward stroke of the rod 3, by which the die 7 is caused to strike one of the dies 17 and the arm 42 is caused to strike the head 40, forces down the head 22 until the lowermost die 17 strikes the work-support 29 and at the same time forces down the foot38 and the corresponding pin 19, which drives the staple seated in the perforation 18 through the material held on the anvil. When the rod 3 rises, the respective springs 33 and 41 lift the head 22 and foot 38 to their normal the shears.

position, while the pawl 25, engaging with a ratchet-tooth 24, brings a succeeding die 17 under the striking-die 7 and a diametrically opposite die 17 over the anvil 29.

The feed mechanism comprises a frame 44, having arms 45, which are revolubly supported on the head 2, the position of the yoke and the angle at which the ribbon shall be fed being accurately determined by means of a gage 46, while the parts are held in the position to which they maybe adjusted by means of a set-screw 47, which passes through a slot 48. A reel 49, journaled at 50 upon the frame, carries the metallic ribbon 15, which is fed over the shear 12, beneath the guide 14, by the rollers 52 52, journaled in the frame, a positive action of the rollers being secured by means of the engaging gear-wheels 53 53. A ratchet-wheel 54, fixed to the roller 52, is engaged by a pawl 55, which is pivoted on the rocking arm 56. The arm 56 is pivoted to one end of a link 57, the opposite end of which is pivotally connected with a bearing movably fixed in a slot 58 of alever 59. The lever 59 has one end pivoted on the frame 44 and the opposite end pivoted to a link 60, which has a second pivotal connection with an arm 61, longitudinally fixed but revolubly movable on the rod 3, the arm being guided in its reciprocation by a rod 62 passing through it and fixed to the frame. It will be seen that by this mechanism the angle at which the blank is shorn from the metallic ribbon, and consequently the length of the prongs, may be varied by varying the position of the frame 44, and consequently the angle at which the metallic ribbon is fed to It will also be seen that by moving the connection of the link 57 with the lever 59 the rate of feed and the proportions of the staple may be varied. The angle at which the staple-blank is cut may also be varied by providing means for changing the position of the die-shear 7 and the shear 12. This may be done by providing a revoluble connection between the rod 3 and the head 6 and employing a set-screw 6 for holding the die-shear 7 in the position to which it may be adjusted, and for correspondingly changing the lower sheara shear 14', revoluble in a seat 15, may be employed and fixed in the position to which it may be adjusted by means of a set-screw 16 passing through the shear-slot 17 and the seat 15.

It will now be seen that the oscillation of the lever 4, which reciprocates the rod 3 upon the downward stroke, causes the shears 7' and 12 to cut from the tape or ribbon 15 the blank 16, and the die 7 with its pin 3, aided by the die 17 and its pin or plunger 19, to form the staple 20. The downward stroke, which forms the blank and staple in the uppermost die 17, forces down the head 22 until the lowermost die 17 strikes the material on the anvil 29, and the foot 38, driven down by the arm 42, strikes the plunger 19, which sets the staple that is seated in the perforation 18 and rivets it in the work supported by the anvil. Upon the upward stroke the pawl 25, engaging with a teeth 24, advances the ring or collar 21, bringing a succeeding die 17 under the die 7 and a succeeding die 17 over the anvil 29, while the springs 33 and 41 elevate the head 22 and the foot 38, and coincidently with this operation the feeding mechanism connected with the rod 3 causes the feed-rollers 52 52 to advance the tape sufficiently for the production of a succeeding blank and staple. By adjusting the shears 7' and 14' or by adjusting the frame 44 the angle at which the tape or ribbon 15 is shorn may be varied, and by adjusting the connection of the link 57 with the lever 59 the length of ribbon fed at each shearing operation may be varied. Hence the diamond-shaped blank and the staple formed therefrom may readily be varied at will.

Having thus described our invention, we claiml 1.
