The following particulars, furnished by the Aylesbury Dairy Companj', give 
a short description of the most important parts of this Separator, and au 
explanation of its working : — 
The drum is a vertical cylinder loj inches in diameter, and lOJ inches high, 
■with a cone-shaped bottom, and an annular top, the aperture of which is 
9J inches in diameter. It is enclosed in a cast-iron casing, and rests on a 
spindle, to which the necessary speed of 2800 revolutions per minute is given 
by a driving-strap passing over a floor-pinion. A space or chamber is formed 
for the heavier part of the milk, i.e., the skim-milk, by an annular plate 
fixed one inch under the cover or upper internal flange of the drum, a narrow 
slot or groove being left for the entrance of the skim-milk between the cir- 
cumference of the plate and the inside of the drum. The milk is by means 
of the two outlet tubes of Professor Fjord's Regulator conducted to the bottom 
of the drum, and, being immediately forced by centrifugal power to and up 
its sides, forms what is virtually a cylinder of milk , at the same time the 
centrifugal force effects a separation of the heavier from the lighter parts of 
the milk, so that the outer wall of this " milk cylinder " is composed of skim- 
milk, and the inner surface of cream. Tlie skim-milk passes upwards through 
the slot or groove above referred to into the chamber between the annular 
plate and the top of the drum, and is drawn off by means of a tube fastened 
to the cover of the external casing, and bent to reach into the chamber. A 
similar tube bent to reach below the plate draws off the cream. The relative 
proportions between the cream and skim-milk can be altered during the 
motion of the machine by sliding the two draw-off tubes lengthwise back- 
wards or forwards, and a further advantage which this Separator possesses 
over others is that, if required, it will, by means of elevating tubes, deliver 
both products at a height of 8 feet above the drum. 
The Separator is designed to take the cream from about GO gallons of milk 
per hour, with an expenditure of force much less than that generally known 
as " a horse-power." The cream is delivered into a cream-can, and the skim- 
milk is raised by the centrifugal force to a considerable height into a large 
Lavsrence's refrigerator, or, as may be generally deemed convenient, into a 
new warming and cooling apparatus by the same makers, and thus described 
by them : — 
Article 6. — Improved Patent Apparatus for heating and cooling 150 gaUons of 
Milk per hour; manufactured by Lawrence and Co., Limited, 22, St. Mary Axe, 
London, E.G. Price 301. 18s., fitted complete. 
The skim-milk thus treated is conveyed into ordinary railway milk- 
churns and is used partly for immediate consumption in the Showyard 
AS a beverage — as is largely the case with the separated milk from English 
butter-factories. 
Each "churn" of milk is conveyed from the truck to the Swedish (Laval) 
Separator, and is raised to the necessary height by means of a smaller 
Lewis's Milk-can Lifter {Article 3) which lias already been described on p. 43. 
The price of this smaller implement is G/.
