My invention consists in the combination, of a churn-box and gear wheel, with a broad horizontal shaft and dashers; the dashers passing through the shaft obliquely; and also in peculiar counter beaters in the lower part of the box.

The object of my invention is to improve the efficiency of box churns, by giving the cream both a rotary and a longitudinal motion, and at the same time to force a sufficient amount of cool air through the cream to prevent its becoming heated by friction or agitation. The advantages of the diagonal dashers and broad shaft are as follows: A complete reaction is produced in the cream by the dashers at each half revolution of the shaft, and the shaft being flat and broad, the cream in the centre of the churn is agitated equally with the rest. Although this churn is extremely simple in its construction, yet by its peculiar reaction on the cream, I am enabled to churn in from three-quarters of a minute to three minutes, and make as much and as good butter as any churn in use.

liability to shrink, swell, split, &c., so unavoidable in wooden machines, is prevented. The spiral springs over the rolls render this machine self adjusting, so that small and large articles, as well as articles uneven in thickness, are certain to receive uniform pressure.

The patent fastening, by which the machine is tightened to the tub, we believe to be superior in simplicity and efficiency, to anything yet offered.

It will wring thoroughly anything, from a single thread to a bed quilt, without any alteration whatever.

No thumb-screws or complicated fastenings to wear out or get out of order; it can be faetened firmly to the tub in a single second.

Among the collection exhibited by Baldwin, Dewitt & Co., were the following machines:
