This was intended to be an inexpensive globe for classroom use in which the students would have these at their desks while the teacher would lead the lesson with a larger globe. For the teaching of geography, it offers an innovative feature that the company called a “sliding clamp” which allows the meridian to be adjusted at different angles relative to the vertical “upright wire” attached to the base. Loosening the clamp permits the meridian to slide; tightening it secures it in place. Other examples of this globe exist, with different text on the base, advertising the products of the Denoyer-Geppert Company. Those were probably promotional items.
The base explains how to use the sliding clamp:
SUGGESTIONS FOR USE
For most work in geography your city should be on top. Turn the semi-meridian one half turn to the right and slide it so that your antipodes (the place exactly opposite to you) comes directly over the upright wire. Tighten the meridian. Place the semi-meridian in a north and south plane with the north pole to the north. It is now possible to see where the different countries or continents are from your location.
For teaching change of seasons set the globe so that the Antarctic Circle is just over the upright wire. For further suggestions consult “Manual Accompanying Cartocraft Globes.”
