Abstract
Rotary magnetic file including a base having a bottom and two sides. A shaft is mounted between said sides and a magnet is rotatably mounted on the shaft. A pair of magnetic members are mounted on said shaft at each side of said magnet. A pair of spacer members are mounted on said shaft on the outside of each magnetic members, the average diameter of the magnetic members being equal and less than the diameter of the spacer members. The edge of the spacer members adjacent to the magnetic members is gradually decreased to the dimension of the magnetic members. Index cards with clips of magnetic material may be mounted on said magnet and or magnetic members, the clips being formed to fit between the spacers in a self-centering manner.
Claims1
Rotary magnetic file comprising:
- a base having a bottom and two sides,
- a shaft mounted between said sides,
- a magnet mounted on said shaft,
- a pair of magnetic members, one mounted on said shaft, at each side of said magnet, the magnet and the magnetic members being rotatable with respect to said sides,
- a pair of spacer members, one mounted on said shaft on the outside of each magnetic members, the average diameter of the magnet and magnetic members being less than the diameter of the spacer members,
- the edges of the spacer members adjacent to the magnetic members being gradually decreased to the dimension of the magnetic members, and
- a plurality of clips of magnetic material mounted on said magnet and magnetic members, the clips being formed to fit between the spacers in a self-centering manner,
- the dimension of the clips in the axial direction of the magnet being several times larger than the magnet.
