Description: |
| "My improvements more especially to the portable wheat-flouring and corn-grinding mill of Mr. Isaac Straub, which is now used extensively in the western and southern States, the characteristic of which is, that the lower stone is the 'runner,' whilst the upper one is stationary; and the object of my improvement is to avoid the possibility of the mills getting out of 'tram,' from the terribly rough and careless handling to which they are subjected by steamboat and railroad transportation..." |
