De Laval Magnetic—the 
World’s Best Milker 
De Laval Principle of Fixed and Uniformly Con¬ 
trolled Pulsations Proves Its Superiority 
In practically every de¬ 
tail of construction the 
De Laval Magnetic Milker 
is superior, but its chief 
feature, distinguishing it 
from all other milkers, is 
the principle of fixed and 
uniform magnetic pulsa¬ 
tion control. 
It is largely due to this 
exclusive and patented 
De Laval feature that the splendid milking 
results of the Magnetic Milker are obtained, 
and the simplicity and reliability of operation 
for which these Milkers are famous. 
Judged on the basis of efficiency, speed, and 
thoroughness of milking, on simplicity and 
reliability of operation, on quality of con¬ 
struction, on its ability to produce clean milk, 
the De Laval Magnetic is supreme. The 
simple truth is that the Magnetic is in a class 
by itself in Milking Machines. 
Should anyone question these claims, he can 
satisfy himself by making an investigation 
among De Laval users. Better still, a Mag¬ 
netic tried side by side with any other Milker 
in actual use will convince any fair-minded 
person of De Laval superiority.

Rate of Milking. The capacity of each 
Milker unit is from eight to ten cows per hour. 
This can be increased to twelve and fourteen 
per hour by fast operators. One man can 
operate two to three units and do his own 
stripping, carrying milk, weighing, etc. If he 
has some help, he can easily operate three to 
four units. If he has two assistants, he can 
operate six units. 
De Laval Utility Milker 
While De Laval Util¬ 
ity outfits have many 
De Laval patented fea¬ 
tures, they embody a 
less expensive construc¬ 
tion than the Mag¬ 
netic, which enables 
them to enter a lower 
price field. 
The Utility is a qual¬ 
ity Milker in every respect, and the best 
Milker of its kind that money can buy. 
The pulsator used on the Utility units is of 
an ingenious membrane type that has only 
three moving parts. It requires no lubrica¬ 
tion and seldom regulation. The pulsator is 
easy to take apart and is the best pail pulsator 
of its type that has ever been made. 
Utility Milker units are provided with one- 
piece teat-cups. The shell is a single piece and 
the liner and milk-tube are a single piece of 
rubber. 
Utility units are provided in either single 
or double unit type.
