It is thou ht that the construction, operation, and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been'disclosed in detail merely by way ofaexample since in-actual practice, it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. It will be .ap parent that the changes in the details of construction, and in the combination and arrangement of parts may be resorted to, with:

out departing from the spirit or scope of the invention as hereinafter claimed or sacri ficing any of its advantages.

Having thus described my invention, what I claim is:

In amixing machine, a supporting structure having an internal gearfixed thereto, a drive shaft rotatable on said structure and having its axis coincident with the axis of said gear, a driven shaft parallel to said drive shaft and having a pinion thereon in mesh fvvith said gear, means for rotatably-supporting saidfdriven shaft on said structure, an internal" gear fixed to said driven shaft, and a pinion on the drive'shaft in mesh with the last named internal gear.
