39,182	Jul. 07, 1863	Improvement in sugar-cane-crushing mills	Isaac Straub	Cincinnati, OH	This patent date, along with that for patent 22,802, is reported on a Pioneer No. 1 sorghum press made by James L. Haven & Co. Abstract: In all cane-crushing mills of the upright class it is necessary to provide against the stalks getting out at the ends of the crushing-rollers during the operation of the latter in expressing the juice from the stalks of cane, and thereby clogging up the machinery. To this end the upper and lower journal-plates have been fitted in close contact with the ends of the rollers; and in another case annular grooves have been made in the ends of the rollers, into which were fitted corresponding projections or rings cast on the plates of the frame; and other plans have been essayed for this purpose, all of which are found more or less objectionable from the fact that the crushed cane will in time work its way between these contiguous surfaces, clog and derange the machinery, beside rendering it difficult of operation. The nicely-fitting joints soon become choked with dirt, oil, and cane-juice, and the mills require frequent cleaning and repairing. The object of my invention is to remedy these evils in a sugarcane mill, by dispensing with all closely-fitting joints or surfaces at the ends of the crushers, which would be liable to get clogged with crushed cane and to provide a means which, while it serves to keep the cane from escaping at the ends of the crushers to any material extent, will not create any injurious friction nor permit the accumulation of cane or other matters at these points. The nature of my invention consists in leaving wide spaces at the ends of the crushing-rollers and between them and the top and bottom plates of the supporting-frame, and in interposing directly above and below the bite of these rollers curved guards or fenders, which project over or beyond the ends of all the rollers short distances. Claim: The arrangement of projections G-G' on the under side of the top plate, A, and on the upper side of the bottom plate, A', and so that the ends of the rollers for only a small portion of their extent, and immediately at the point where the crushing is performed, shall abut against them.

74,774	Feb. 25, 1868	Improvement in portable grinding-mills	Ambrose W. Straub	Philadelphia, PA	"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..."
