"~ PRAIRIE STATE UNIVERSAL HOVER 



It maj' 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 organ box. It also 

 enables those who wish to build their own brooders to get the best brooding dovice pos- 

 sible in an economical manner. It fills tliat 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 b-^ road from t'le ontside without disturbing 

 any part of the brooder. The lamp used is made of metal, using a No. 2 S .u Hinge 

 liurner and a metallic chimney seven inches in length, thus assuring a stoa.;.v. bright, 

 clear flame ; the lamp being on the outside of the brooder in view at all times. Sur- 

 rounding the hot-air flue or chimney is a fresh-air pipe through which fresh air, slightl.v 

 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 a.i additional 

 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 maiiitaiiiod without close atten- 

 tion. It is not essential, but a great convenience during the cold, changeaMe weather, 

 and greatly aids the operator in supplying the desired conditions for newly hatched 

 chicks, I'caevii'.g him of any cause of worry concerning the brood.

THE PRAIRIE STATE PORTABLE HOVER 



The Prairie State Portable Hover embraces in principle and construction all 

 those original and successful features which at once established the high reputatiop- 

 of the Prairie State Universal Hover. It is a Universal Hover so modified as t( 

 hriag the lamp case to the floor level without sacrificing safety, economy of oil 

 consumption, or ventihition, and involving attached lanip case and all-steel con- 

 struction. It is a Portable Hover built along lines different from all others. Con- 

 t'-ary 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 de- 

 tachable from the hover proper, if so desired, being quickly attached by a uniciue 

 and simple clamp, distinctively Prairie State. The arrangement 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 voung chicks to crowd against such obstructions is well 

 known, and the danger from crowding against hot or cold drums is easily rfc 

 cgnized. Furthermore, in hovers involving location of lamp at the center, th(M( 

 is the add-'d danger resulting from similar tendency to approach a light, or ti 

 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 cur- 

 rent of air is taken in through screened openings near the base of the lamp box, 



is forced therefrom throuph 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 exactl.v 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 ho-^er. 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. 1

 temperature. A stroiig point in the nursery is the circular hover without ob- 

 structions of any kind, sLich as hot drums or domes, leaving every inch of inside 

 space available for the chicks. It is open all around. No cold corners or hot 

 spots to crowd into. A glass door in front, 22 inches wide, furnishes light and
