~ ^ PRAIRIE STATE UNIVERSAL HOVER 



It may be attached to any form of outdoor brooder, two feet or more in height, to 

 any size or form of colony house, shed, coop, piano, dry goods or oi-gan box. It also 

 enables those who wish to build their own brooders to get the best brooding device 

 possible in an economical manner. It fills that want, felt by everyone who raises 

 poultry, for something they can use anywhere, any time, and do the work well. 



The hover is twenty-two Inches in diameter, the top of which is wood, lined with 

 strawboard, a 4-inch rim extending downward, to which is attached six inches of felt 

 curtains. The hover stands on three Iron feet, but is not stationary, and may be 

 raised and moved instantly, if desired. 



A thermometer is provided, which may be read from the outside without disturbing 

 any part of the brooder. The lamp is made of metal, using a No. 2 Sun Hinge Burner 

 and a metallic chimney seven inches in length, thus assuring a steady, bright, clear 

 flame; the lamp being on the outside of the brooder in view at all times. Surrounding 

 the hot-air flue or chimney is a fresh-air pipe through which fresh air, slightly 

 warmed, is injected into the upper part of the brooder. This diffuses downward and 

 through the curtains, thus furnishing a perfect system of ventilation. At an addi- 

 tional cost of $1 to the regular price a standard Wafer regulator may be attached to 

 the hover, by the use of which a uniform temperature can be mainlained withoutclose 

 attention. It is not essential, but a great convenience during the cold, changeable 

 weather, and greatly aids the operator in supplying the desired conditions for newly 

 hatched chicks, relieving him of any cause of worry concerning the brood. 



—Price for fiover, with lamp case, smoke conductors, lamp and thermometer $7.00 



ne, lamp case and smoke conductors are not required. Hover and lam; 6.00 



Hover regulator, $1.00 extra.

THE PRAIRIE STATE PORTABLE HOVER 



The Prairie State Portable Hover embraces in principle and construction all 

 those original and successful lealures which at once established the high repu- 

 tation of the prairie Stal;e Universal Hover. It is a Universal Hover so modi- 

 fied as to bring the lamp case to the floor level without sacrificing safety, econ- 

 omy of oil consumption, or ventilation, and involving attached lamp case and 

 all-steel construction. It is a Portable Hover built along lines different from 

 all others. Contrary to general practice in building Portable Hovers, we have 

 so designed this hover as to furnish a lamp case which is a separate unit in 

 itself, entirely detachable from the hover proper, if so desired, being quickly 

 attached by a unique and simple clamp, distinctively Prairie State. The ar- 

 rangement is therefore such as to prevent interference in the hovering space 

 by the intrusion of any part of the lamp box or by other drums or similar 

 obstructions. This is to be particularly noted, for the tendency of young chicks 

 to crowd against such obstructions is well known, and the danger from crowd- 

 ing against hot or cold drums is easily recognized. Furtliermore, in hovers in- 

 volving location of lamp at the center, there is the added danger resulting from 

 similar tendency to approach a light, or to huddle in spots which are warmer 

 than the space surrounding. Removal of all such obstructions, with uniform distribution of heat from above in all parts of the 

 hover, renders every square inch of the hovering space equally available to the chicks, and is an exclusive characteristic of 

 Prairie State Portable Hovers. No other Portable Hover now on the market provides a heating power equal to that of the Prairie 

 State, with a correspondingly low rate of oil consumption and an equivalent volume of fresh air constantly forced in for free 

 ventilation. This current of air is taken in through screened openings near the base of the lamp box, is forced therefrom 

 through a space- between the smoke pipe and its outer jacket into the body of the hover just under its top' and is there radiated 

 and diffused downward, passing out under the curtain. The principle is exactly that of the Prairie State Universal Hover In its 

 passage this fresh air current at once cools the lamp to a degree which lowers oil consumption and is at the same time warmed 

 before entrance into the hover. It is readily seen what a contrast this method forms to the poorly located lamp and bad ven- 

 tilation of center lamp types.

The Combination Colony Brooder, No. I 



This Brooder House is constructed of tongued and grooved boards. The 

 brooder is full size in all dimensions, 3 feet wide, 6 feet long and 3 feet high 

 in front and 2 feet in rear, with tin roof. The interior is divided by a mov- 

 able partition into two compartments — the nursery room and the exercising 

 room or sun parlor. The nursery is double walled, top and sides, with dead- 

 air space and paper insulation between the board partitions, securing 

 warmth and uniform temperature. A strong point in the nursery is the cir- 

 cular hover without obstructions of any kind, such as hot drums or domes, 

 leaving every inch of inside space available for the chicks. It is open all 

 around. No cold corner.^; or hot spots to crowd into. A glass door in front, 

 22 inches wide, furnishes light and access to the chicks. A movable board 



under the door 



brings the opening 

 level with the floor 

 of nursery and per- 

 mits easy cleaning 

 of the apartment. No,

The Combination Colony Brooder, No. 2 



This Brooder is similar to the No. 1 in construction and is 60 inches 

 long, 30 inches wide, 20 inches high in rear and 30 inches in front. 



The interior is divided into two large compartments by a movable par- 

 tition — the nursery room and the sun parlor or exercising room — the floor 

 throughout being on a level and S inches from the ground. Be- 

 tween the nursery and exercising room is an opening 18 inches 

 wide, with a wooden door, hinged to open and close at will, so 

 when desired the chicks may be confined in either apartment. 

 With the wooden door opened, the space is covered with a 

 heavy felt curtain, slit for easy passage of the chicks back and 

 forth. Two glass doors, 26x14 inches, furnish access to the 

 chicks confined. A movable board below the glass door brings' 

 each opening level with the floor and permits easy cleaning of 

 each apartment.
