two concentrically rotating lower and upper disks 22 and 24 as it appears in actual operation the lower disk 22 is located below or underneath the disk 24 hence the upper disk 24 is located above or on top of the disk 22 each the disks 22 and 24 have central first and second apertures 26 and 28 respectively adapted to receive a rivet 30 in fig1 the lower disk 22 and the upper 24 are shown rotably connected to each other via the rivet 30 inserted through concentric apertures 26 and 28 the recipe sizing wheel 10 is made up of the lower disk 22 as shown in fig3 and the upper disk 24 as shown in fig2 the disks 22 and 24 are connected together in their centers by the rivet 30 as illustrated more fully in fig3 the recipe sizing wheel 10 operates by rotating the upper disk 24 in a prescribed manner with respect to the lower disk 22 to calculate less than full portions or multiples of portions for which a recipe is written or expressed the recipe sizing wheel 10 allows any cook or chef that uses recipes whether from a cookbook magazine or newspaper etc to quickly effortlessly and accurately reduce or increase the number of servings a recipe prepares as illustrated in fig4 the rivet 30 has an elongated shank 32 about which the disk 22 and the disk 24 each freely rotate.
