Definitions

  • This invention relates to press attachments and has for its 'ObJQGt, the provision of means for feeding stamping and emboss ing material as roll leaf, metal leaf and the like under predetermined conditions which govern the rate and extent of feed.
  • Another object includes the provision of a construction which is compact and selfcontained, so as to be readily handled and quickly transferred from one stamping press to another. I further place the feed rolls at an angle to the feed table, thereby providing an arrangement for readily threa ing the strips of stamping material through the machine and correctly locating the same on the feed rolls.
  • a further object includes the provision of means for quickly adjusting without tools, the machine to vary the extent of stamping material pulled by the respective feed rolls to suit the work at hand.
  • Another object embraces the provisionof a compact and entirely self-contained machine which has comparatively few parts, is easily transported and is comparatively cheap to manufacture and readily replaced.
  • Fig. 1 is a plan view of a construction embodying the principles of my invention.
  • Fig. 2 is a side elevation thereof showing the adjustment mechanism.
  • Fig. 3 is a view taken on the line 3--3 of Fig. 1.
  • Fig. 4 is a View taken on the line 4.-4 of Fig. 1.
  • Fig. 5 is a view taken on the line 5-5 of Fig. 1. r
  • Fig. 6 is a view in section showing the ratchet clutch.
  • Fig. 7 is a view showing a manner of tensioning the idler rolls and Fig. 8 is a view taken on the line 8-8 of Fig. 4, looking in the direction of the arrows.
  • stamping and embossing'press attachment which is self-contained and wherein one of the main features of construction provides means for feeding the roll leaf slowly and uniformly to the desired extent without damaging or tearing the carrier strips during the feeding operations.
  • the leaf is fed. with uneven or jerky motions, thereby causing the carrier strip to tear and cause trouble by catching in .the rolls.
  • Even under the most favorable conditions the used strip has a tendency to tear because in the stamping operations the die which-transfers the stamping medium from the carrier strips to the article stamped has tendency to perforate the carrier strip, thereby weakening-it greatly.
  • I utilize a torsion spring which is wound with the movement of the press platen and the torsional stress of the spring is then utilized in causing the roll, or rolls, to advance at a slow and predetermined speed, which is controlled by a regulating governor or con trol device.
  • This device may be any suitable control mechanism, as a geared electric motor, or a suitably placed dashpot, or other means whereby the feed movement of the rolls is properly retarded.
  • a geared electric motor or a suitably placed dashpot, or other means whereby the feed movement of the rolls is properly retarded.
  • the governor or control device is an electric motor which retards the return movement of the spring and therefor also the control feed roll, or rolls, in the manner to be stated more fully herein-after.
  • the frame or bed plate is provided with inclined end arms 11 and 12 and with press attachment means in the form of a dove-tailed lug piece 13.
  • the latter piece fits into a slot 14: on the press frame 15 readily attaching the mechanism to any standard press suited for using metallized roll leaf in ornamenting, stamping and embossing or the like.
  • the arms 11 and 12 carry the mainor feed rolls 16 and the idler rolls 52 together with the operative parts associated therewith.
  • Journal 22 is also providedwith a head 25 which isfastened to the said journalby a pin 26.
  • the journal head 25 is provided with a crank arm 27 which engages the re winding plunger stem 28 ofplunger piston 29.
  • This plunger operates in the dashpot in cup 18 and the stem extends through the floor of the bed plate in a bearing 30 tobe positively moved upwards by the press platen (not shown) 1 to wind up the torsion spring 31 for operatingthe teed rolls.
  • a set screw 32 provides means for proper adjustment between the press platen and the i the journal 22 by a pin 38.
  • plunger stein One'endot' spring 31 is fastened onto the casing and the other is tastened onto a sleeve 33 which is secured to This arrange ment causes spr1ng31 to be tensioned or wound up when the plunger 28 is raised.
  • the cords 39 pass over the pulleys 4C1 on the outer roll and the end of each cordis fastened to the individual roll sleeve 12; which is rotated by the pull of the cord against the tension of a suitable spring 43 within the roller sleeve.
  • One end of this sleeve is carried on a bearing 4 1 and row, the ball will remain ine'itective.
  • This clutch comprises a )lurality of clutch balls 16 which are held y a spring 47 inoperative position. While the head is rotated counter clockwise in the direction of the ar- When, l'lQWQVGI, the motion is reversed, the balls will ride up the incline plane in the head and grip on the outer surface thereby locking the sleeve and its attachedroll 16 against rotation in that direction.
  • the feed rolls 16 are supported in the frame arms 11 and 12 and the manner best shown in Figs. 1 and 5. In the 1 construction shown three full rolls are. provided, but obviously the number of rolls employed may. vary to meet required or desired needs. of these rolls is alike and therefore a de- SCl'lPillOl'l of one of the rolls will suffice.
  • the roll body 16 is companion roll 52 which is here shown as an idler.
  • Ajournal 18 is provided with bearresponse to the pull and in the direction stated above.
  • An end clutch 51 similar in consiruction to its companion clutch 45, but oppositely placed, controls the directionot pendent rotation of each feed roll in the same direction, which is hereln counter-clockwise,
  • the companumroll 52 is pivotally held on a rocker armj53 and rstensioned to grip the leaf roll by means of a tension spring 54, the free end of which is hooked on a finger ice 55 project-ingt'rom the frame arm 11 at one end and from the frame arm 12at the other.
  • a brake device is provided and this brake device controls the return or unwinding otthe operative spring.
  • a motor governor or retarding device 19 which is conveniently .22 to rotate and wind roses-"1r attached directly ,onto the plate 20.
  • a bush ing '60 in plate 20 is provided for the motor drive axle 61.
  • the motor drive axle carries the reduction gear 61", which operates gears 62 on the bevel gear 62 of known construction, .and provides means for reducing the rate of rotation in proper ratio of the motor axle and the sleeve gear 63, which is driven from gear 62.
  • the sleeve gear 63 is loosely mounted on sleeve 64, which is carried freely on the journal 22. On the flange of the sleeve gear 63 there is secured by suitable means, as a key 63 the silent ball clutch 45, which is surrounded by the journal hub extension 65 and is secured to the journal 22 by a pin 80.
  • the operation of the retarding construction is as follows:
  • the printing platen strikes the lower end, or set screw 32 of plunger 28, and by pushing up this plunger, causes journal up spring 31.
  • the plunger 28 and arm 27 will then assume the position shown in Fig. 3 and by reason of .the spring tension will unwind or move in the direction indicated by the outer arrow in Fig. 8.
  • the rate of the unwinding will be controlled by the motor through the retarding gears and the clutch about as follows:
  • the retarding sleeve gear 63 and the clutch 45 being united will rotate in unison in the direction indicated by the arrows on the clutch (Fig. 8) and the rate of rotation will be constant and controlled by that of the motor.
  • the motor shaft 61 also carries at its end a bevel gear 67 which meshes with a sleeve gear 68.
  • the latter gear is fastened onto the sleeve shaft 64, which is loosely mounted in journal 22.
  • the sleeve shaft 64- is further provided with a standard type of friction clutch 69 for automatically operating the contact device 7 0 of known cam structure, on journal 22, whereby the motor circuit (not shown) is automatically closed during the return motion of journal 22, so that the motor is in operation only during the return motion of the journal 22, and its connected head 25 and arm 35.
