Definitions

  • ABSTRACT A character dial assembly used with a machine for engraving characters on finger rings and other metallic ornamental articles, which comprises a lower circular dial member and an upper circular dial member having a diameter smaller than the lower dial member.
  • Each of the two dial members has its upper surface engraved with a set of various characters which are disposed circumferentially on the dial member in equal spaced relationship with one another.
  • the lower dial member also has its upper surface impressed with index characters on its upper surface corresponding to the characters engraved thereon and disposed radially outwardly of the corresponding engraved characters.
  • the upper dial member has a cut out section for obtaining access to the engraved characters on the lower dial member.
  • the lower and upper dial members are coaxially connected together for rotation relative to each other.
  • a character dial for use with engraving machines and the like is generally required to have about 60 to 70 characters engraved on it, including Arabic numerals, capital and small alphabetical letters and associated symbols.
  • this large number of characters was put on a single dial by engraving on both sides of the dial.
  • the use of such a dial is cumbersome because the dial must constantly be turned over in order to fully select from all of the characters on the dial and in order to properly position the desired character with relation to the engraving machine.
  • this type of dial was usually fixed to the engraving machine by screws which had to be removed each time the dial was turned over.
  • dials were provided which had engraved characters on only one side of the dial.
  • the size of the dial had to be so large that it could no longer be fixed directly to the machine bed of the finger ring engraving machine or the like, and thus it has become necessary to employ a suitable attachment for mounting the dial to the machine bed.
  • the present invention provides a character dial assembly having an upper circular dial member rotatably mounted on a lower circular dial member.
  • Each of the two dial members has its upper surface engraved with a set of various characters disposed in a circular pattern in equal spaced relationship with one another. The diameters of the circular patterns on the upper and lower dials are approximately equal, while the diameter of the lower dial is larger than the diameter of the upper dial.
  • the lower dial member also has its upper surface marked with index characters corresponding to the engraved characters and disposed outwardly of the same engraved characters.
  • the upper dial member has a cut out portion to allow access to the engraved characters on the lower dial member.
  • the sets of characters engraved on the upper surfaces of the two dial members may include Arabic numerals, capital and small alphabetical letters and associated symbols.
  • FIG..4 is an exploded view of a portion of FIG. 3.
  • reference numeral 1 designates a finger ring engraving machine well known in the art as, for example, the type shown in U.S. Pat. No. 2,562,269 issued July 7, 1951 to G.G. Gruettner et al.
  • the engraving machine 1 includes a machine bed 2 having three support projections 3a, 3b, and 3c formed on the upper side thereof for stably supporting a character dial to be described.

  • the dial assembly comprises a lower circular dial member 8 having a central opening 9 formed therethrough for detachably mating with the outer side wall of the dial mounting cyl inder 7 of the finger ring engraving machine 1.
  • the upper face of circular dial member 8 includes several concentric annular surface areas delimited by various imaginary circular lines.
  • a first or innermost annular surface area is a circle of engraving characters, delimited between imaginary lines 30 and 31.
  • the engraving characters such as Arabic numerals, capital alphabetical letters and associated symbols, indicated as 10, are engraved in the upper face of the dial. All of these characters are equally spaced apart and sized to the width of the annular surface area between circles 30 and 31.
  • a second or intermediate annular surface area is a circle of indicia delimited between imaginary lines 33 and 34 which consists of a set of index characters 1 l, duplicating the set of engraving characters 10.
  • the index characters are impressed on the dial and positioned to correspond to the position of the engraving characters 10 in the first annular surface area.
  • the thickness of the dial member 8 is smaller than the length of the dial mounting cylinder 7 which is projected upwardly of the machine bed 2 of the finger ring engraving machine 1.
  • the dial assembly further comprises an upper circular dial member 13 having a diameter somewhat smaller than that of the lower dial member 8.
  • a cut out 14 for viewing and obtaining access to a predetermined number (at least one) of the engraved characters on the lower dial member 8.
  • the annular surface area of the upper dial member 13 which contains the cut out portion 14 includes a circle of engraving characters delimited between imaginary lines 30 and 37 in FIG. 2. These engraving cha'racters indicated as 15, such as Arabic numerals, small alphabetical letters and associated symbols, are engraved on the upper face of dial 13 and are equally spaced apart.
  • the upper dial member 13 has a centrally disposed circular opening whose inner wall 38 provides a stepped portion 16 like a staircase.
  • a check plate or flange member 17 is connected to the lower dial member 8 by screws 19.
  • the flange member 17 has a central opening 41 (FIG. 3) and an outer circumferential edge which provides a complementary stepped portion or flange surface 18 for mating with the stepped portion 16 of the upper dial member 13 and a guide surface 39 for coaction with the inner wall 38 of the upper dial member 13.
  • the check plate 17 Secures upper dial member 13 to the lower dial member 8 while allowing the upper dial 13 to rotate with respect to the lower dial 8.
  • a substantially circular recess 20, as deep as the stepped portion 18, is formed in the check plate 17 at a portion adjacent to the outer circumference thereof.
  • a set screw 21 is received in the recess 20 to fix the upper dial 13 to the lower dial member 8.
  • the set screw 21 is threaded into a threaded hole 40 in the lower dial member 8 through a small aperture 20a formed centrally of the recess 20 in the check plate 17, thereby fastening the upper dial member 13 to the lower dial member 8.
  • a knob or handle 22 is detachably screwed into the upper dial member 13 and has a recess formed in the lower end face thereof for resiliently receiving a slide ball 24 which is engageable with several small recesses 23 formed in the upper side of the lower dial member 8.
