This led to con-tinuous milk and cream discharges, and consequently also tothe continuous inflow of whole milk. These machines wereof the hollow-bowl construction. Modern Separators.—Since the year when the Danish Westonand the De Laval machines were invented, many differenttypes of separators with different contrivances within the bowlhave been put upon the market. Baron Bechtelsheim, ofMunich, is given the credit of having discovered that certain. Fig. 71.—The United States separator. contrivances on the inside of the machine increase the efficiencyand capacity of skimming. This discovery was made, accord-ing to J. H. Monrad,* in 1890. This invention was bought bythe De Laval Company. The principal part of practically all the separators is a bowlrotating in a vertical position, with or without contrivancesinside the bowl. Machines having a bowl rotating in a hori-zontal position are, so far as the authors know, not in use atthe present time. Such a machine was once manufactured atHamburg, Germany, and was called Petersons Centrifugal * Dairy Messenger, Jan. 1892, p. 9. SEPARATION OF CREAM. 133 Machine. Another German machine, called The Page, wasalso manufactured in the horizontal bowl style. From the above it will be noticed that fou
