PRAIRIE STATE SAND TRAY INCUBATORS 



The Keystone Series embody in their construction the 

 three principles characteristic of Prairie State Incubators 

 —top-radiant heat, down draft ventilation, and applied 

 moisture. 



TYPE. 



Hot air, as in the Standard Series, free from tanks and 

 consequent danger of freezing or rusting, and proved by 

 years of experience to be the type of highest and most 

 lasting service. 



CASE. 



Double-case construction, inner case or egg-chamber be- 

 ing of soft wood, tongued and grooved, the outer case of 

 cypress — durable, lasting, adaptable to every condition of 

 climate or atmosphere. The case is free from pasteboard, 

 metal linings, oil cloth, or any other substance subject to 

 deterioration. 



I>SrLATIO.\. 



High-grade cotton batting, thoroughly packed between 

 walls of inner and outer cases Extra asbestos, insulation 

 over top of egg-chamber. No "dead air" spaces, no inferior 

 insulating materials. 



PRAIRIE STATE BROODERS 

 AND HOVERS 



NO. KEYSTONE INCUBATOR. 



W^^% ^ 



Prairie State Colony Brooders are built in three sizes, 

 having a total floor space of 18, 12% and 9 square feet, 

 respectively. Numbers 1 and 2 are two-compartment brood- 

 ers, with 1-inch partition in center, forming the hover or 

 nursery room on one side and sun parlor on the other. 

 Access to sun parlor is had by a wide door at bottom of 

 partition, to which is fitted a slit cotton velvet curtain to 

 afford easy passage for the chicks without losing heat from 

 the nursery room, and also a board door by which the birds 

 may be confined to the nursery If desirable. 



The Number 3 Colony Brooder has but one compartment, 

 the hover being located at one end. In this Brooder and 

 in Number 2, hovers of Prairie State Universal type are 

 used, 20 inches in diameter. The lamp is fitted into a spe- 

 cial compartment under the brooder floor, access to the 

 hover being had through the floor. The Number 1 Colony 

 House uses a standard Prairie State Universal Hover with 

 lamp case. In all three the fumes are piped out to the 

 open air through a combination elbow and tee pipe.

PRAIRIE STATE PORTABLE HOVER 



This hover is the m 



latest product of m 



modern manufac- R 



turing methods, and .„,f\. 



is the recognition 

 on the part of our 

 designers of a rap- 

 idly increasing de- 

 mand among poul- 

 try producers for 

 a hover adaptable 

 everywhere and in- 

 stantly portable with minimum labor, light in weight, fire- 

 proof throughout, economical and efficient. The Prairie 

 State Portable embraces all those original and successful 

 features which gave the Universal its instant reputation, 

 and is really the Universal modified to bring the lamp case 

 to floor level, without sacrifice of safety, economy of oil, 

 or free ventilation It is built on lines different from those 

 of all other portable hovers. The hover complete, including 

 lamp case, is made entirely of galvanized steel, insulated 

 thoroughly with non-combustible materials and provided with 

 double curtains of cotton velvet. The steel lamp case, 

 attached to hover by an ingenious method of our own, has 

 conical depression in the bottom which automatically cen- 

 ters the one-piece drawn-steel lamp. It is quickly detach- 

 able and located to one side of the hover, eliminating from 

 the hovering space all possible obstructions such as hot or 

 cold drums, against which the chicks would crowd. 



Made in 2 sizes. 



Large size, 100-chick capacity $18.00 



Small size, 60-chick capacity 11.00
