A wedge-like piece of smooth wood is placed at each end of the 
roller, and acts as a guide to keep the butter from passing off 
the table. The attendant turns the butter over with wooden 
boards : in passing through all the different operations it never 
comes into direct contact with the naked hand. 
Fig. 3. — Mr. Ahlhorn's Prize Mechanical Butter-worker {No. 2118), 
suitable for large Dairies {Class JF.). 
Mr. Hancock's butter-worker (No. 1818) is simply a piston 
working in a cylinder, the bottom of which is perforated by 
numerous small holes. The butter is placed in the cylinder, 
and sufficient pressure is applied to the piston, screwed down so 
as to force the butter in spiral threads through the small orifices 
at the bottom. No. 6348 is an American machine, somewhat 
resembling No. 2118, to which the First Prize was awarded, 
only that a fluted roller is made to work backwards and forwards 
along an inclined straight table.

* The smaller quantity of butter after being washed was in this case due to loss 
by adiiesion to the flannel cover of the piston and to the case of the machines, and 
not to more thorotigh working or pressing-out of the buttor-milk or water.
