  • FIG. 1 A first figure.
  • the present invention relates to a tool formed by a body enclosing a ballpoint pen to which, is affixed, a rod which acts as a point of a compass, and which makes it possible, by using the writing point of the pen, to draw circumferences of predetermined diameters.
  • Such a tool as expected cannot be a tool of exacting precision, but rather it is a practical tool, which allows the use of the ballpoint pen in all usual ways and, furthermore when one needs to make drawings, diagrams, etc. permits the use of compass in order to make use of its special features.
  • a vertical depression is formed with a sufficient cross-section to allow same to receive therein a pivotal compass point arm which, when folded down, fits completely into the outer surface of the case in the depression.
  • FIG. 1 is an axial section of the entire unit; the compass point being shown in dotted lines in an extended position;
  • FIG. 2 is a front elevational view of the ballpoint pen with the compass point arm folded back;
  • FIG. 3 is a top plan view of the ballpoint pen, shown in FIG. 2.
  • the compass ballpoint pen combination comprises a case, made of preferably plastic material, on the inside of which there is a formed a compartment 2, which houses a flexible and replaceable cartridge 4 of the ballpoint pen, the latter ending in a writing point 5.
  • a vertical depression 3 which houses a compass point arm 6 which, when its needle 8 is retracted, fits complementarily into the depression 3.
  • a small grooved wheel 7 is provided in order to adjust the needle 8.
  • the depression is formed with a circular widening just at the height of a wheel 7 and complementary to its periphery 3a, so that it will fit in.
  • a flap 9 is pivotally mounted on a transverse pin 10 in a direction opposite to a couple of vertical grooves 11, which are diametrically opposed and which make possible the free articulation of the flap 9 on the pin 10.
  • a jointed clamp 13 is provided over the pin 10 and astride the flap 9, on which clamp 13, a pommel 12 is screwed, in order to improve the effectiveness of the compass.
  • a compass ballpoint pen comprising a case having curved surfaces and defining an axially offset peripherally closed asymmetric compartment
  • a ballpoint pen cartridge disposed in said compartment and having a pen point extending at one end through said case
  • a compass point arm having a compass point adjacent said one end and being pivotally mounted to the other end of said case at its end remote from said compass point in said depression
  • said asymmetric compartment being narrowest adjacent said other end of said case and widest adjacent said one end
  • said depression being widest adjacent said other end of said case and narrowest adjacentsaid one end, such that said compartment and said depression complementarily define a cylindrical shape throughout the length of said case extending from the narrowest portion of said compartment to the widest portion thereof, said opening of said depression extending substantially less than of said cylindrical shape,
  • said ballpoint pen cartridge extending in said compartment asymmetrically relative to an axial center line of said cylindrical shape
  • said compass point arm being thicker at said end remote from said compass point
  • transverse pin mounted to said case passing through said axial center line and thereat pivotally mounting said compass point arm.
  • said depression has a circularly widened portion
  • a grooved wheel means for adjusting the extent of said compass point on said arm and said means received by said circularly widened portion and fits substantially flush with said cylindrical shape of said case.
