THE HUMANE OIL-O-STAT provides all 
chicks at the same time with comforting, pro- 
tective temperatures. 
MASSIVE HEATER — TILTING CANOPIES 
The Humane Oil-O-Stat is extremely simple and clean 
cut. There are no loose or fragile gadgets. From the 
super-convenient tilting canopy to the double bottom that 
eliminates screens and sand rings, the Humane is 100% 
practical common sense. 
Exclusive Patented Burner (Pat. 20339) 
This all cast iron wickless burner directs twin col- 
umns of heated air around the vaporizing oil, for com- 
plete clean combustion and greater economy. We have 
spent much time and money on burners of all types— 
we find none equal to it for brooder use. Five recently 
issued U. S. Patents cover the exclusive features of 
burner, heater and valve design. 
Only the Humane Oil-O-Stat has the great Twin Blast 
Burner. It was chosen by the Marine Corps as best able 
to meet difficult operating conditions in their radio dry- 
ing oven.

ELECT-O-STAT 
SENIOR — WITH FAN 
THE ELECT-O-STAT has every modern up- 
to-date improvement — plus Makomb quality 
construction. With its High Quality Fan Unit 
—has been known to save over 40% current 
cost in a room at 20°. It is best for cold weather 
brooding, because the ratio of current saved 
increases with the amount of current used. Has 
exclusive 3 way air diffusion through ports 
near the top of the air shaft, air is drawn to 
mix with fresh air. This warmed, vitalized cur- 
rent is pulled down and fanned outward, 
ABOVE tthe chicks. It brushes the elements, 
then part rises to again enter the air shaft 
from above. The rest splits and some escapes 
under the curtains. The remainder turns in 
and back to the fan through an opening just 
above the motor.
