Definitions

  • the present invention relates to a device for simultaneous engraving of a plurality of medallions, plates or like, adapted to replace the single scriber of the conventional pantographs.
  • the present invention refers to a device comprising an element having a plurality of scribers which may replace the single scriber of the conventional pantographs known in the art.
  • the purpose of the invention is to provide a device having a plurality of scribers, adapted to be easily and quickly applied to any kind of the pantographs existing on the market, to replace the conventional single scriber.
  • this multiple reproduction has the advantage of a remarkable increase of the production with respect to the conventional pantographs in the same working time.
  • the number of the scribers, which may be arranged in said engraving element, may be very high, but in practice owing to some requirements of technical nature, it should not exceed 15 scribers, since said scribers should perform the engraving work with the same precision of the single scriber of the known pantographs.
  • This equalized distribution of the engraving force is obtained by a system of equidistribution of the hydraulic pressure on all the scribers within the multiple engraving element.
  • the items to be engraved such as medals, medallions, plates or like, in a number obviously corresponding to that of the scribers, are firmly fastened onto the pantograph table by means of two fastening elements, each fixed onto one of two approachable jaws of the pantographs, each of said fastening elements being provided with projections or like, which form, together with those of the other fastening element, seats in which are locked the items to be engraved.
  • the multiple engraving element 1 consists of a bar 10, having a rectangular cross section and provided with ten engraving points or scribers 2 which are equispaced from one another.
  • a plate 3 is rigidly connected with the element 1 and has two oblong slots 4, into which it is fastened by means of a nut screw 5 a bar 6 making part of an articulated assembly adpted to follow the traverse and penetration movements of the scribers 2.
  • the assembly includes also a bar 7 having two side slots 7 1 for fastening it to the pantograph frame.
  • said bar 7 has two parallel side projections 7" connected by ball bearings 8 with two parallel staffs 9 in turn connected by ball bearings with two parallel end projections 6 1 of the bar 6 by two parallel levers 10.
  • the provision of the ball bearings 8 at the articulation points of the articulated traverse and penetration assembly allows both to follow with the maximal sensitivity and precision the movements of the conventional tracing point of the pantograph and attain a firm support of the bar 1.
  • the multiple engraving element 1 is fastened to a movable arm of the pantograph, at the place of the single scriber, by means of a plate 11 firlmy connected by screws 12 with said element 1.
  • On the plate 11 a block 1 3 freely abuts, said block being fastened to said movable arm of the pantograph by a lock plate 14 pressed onto one side of the movable arm by means of two screws 15 which are screwed into the block 13 through the arm so as to firmly press it onto the other side of said arm.
  • the block 14 has a central hole into which a round rod 16 is inserted, which bar is movable, in opposition to that of the conventional pantographs.
  • a strong helicoidale spring 17 is arranged, which abuts at its lower end on the block 13 and at its upper end on a circular portion of a lever 18 inserted on the rod 16 and pivoted thereon by a pivot pin 19.
  • a small rod 20 is pivoted, the lower end of which is pivoted on a projection 21 rigidly connected with the block 13.
  • a ball handgrip 22 is fastened, which is used during the multiple engraving for pressing the scriber element onto the items to be engraved through the movable rod 16 which may exert a pressure on the element 1 owing to that the other end of the lever 18 is fastened to the block 13 which in turn is firmly secured on the movable arm of the pantograph.
  • the items to be engraved are fixed between two rods 23, shows in Fig.7, each of which is fastened to one of two jaws of the pantograph by means of screws 24.
  • Each rod 23 carries a plurality of circular supports 25, on which are fastened small discs 26 of rubber or like.
  • the item to be engraved is locked between the pairs of the contiguous discs 26 of the jaws.
  • the single scribers 2 are inserted into respective holes of the multiple engraving element 1, preferably of aluminium, and consist of a plug 27 screwed into the upper threaded portion of said hole, a bronze bushing 28 inserted (shrinked) into the lower portion of said hole and carrying in its inside a steel pin 29, the disc shaped end 29' of which abuts on the ring shaped projection 28' of the bushing 28.
  • the seal of said pin 28 is attained by means of an 0-ring 30 and a gasket 31 seals the plug 27.
  • an engraving diamond 35 is fastened by a screw 34.
  • the holes of the scribers which are connected one with another by a longitudinal channel 33, contain hydraulic oil which assures the equalized distribution of the pressure on all the scribers.
  • the operation of the multiple engraving is similar to that of the single engraving.
  • the tracing point is guided by a hand of the operator on the word traced in the model, whereas all the scribers abuting in an initial position on the respective medallions and slightly pressed thereon by the handgrip 22 pushed by the other hand of the operator follow the tracing point and engrave on the medallions the desired word or like.
