BROODER Filed May 18. 1928 known as the-d rip feed,

Patented 1.... 14, 1930 umrsoa's TEs PATENT'VVOFFICE "CLAUDE smnnnia, on enonan, IOWA.

I naoonnn I Application filed Kay 18, 1928. Serial No. 278,855,

for its object to provide a heating unit fora brooder, having novel and improved features of construction. 7

5 Another object of my invention is to provide a combined heating unit and forced draft ventilating system for the brooder.

The stove of m invention is one which may be converts to the t vpe commonly wherein the fuel isallowed to drip from a height through a vertical pipe, which comprises the air inlet onto a vaporizing device, from whence the draft carries it in a horizontal lane through a twisting passageway, in whic it is burned.

Another object of my invention is to provide a heating unit fora brooder, which combines, with the advantages of the winding passageway t ofroil burning stove, the

utmost simplicity, durability and cheapness of construction.

More specifically referring to the last object, it is my intention to construct a stove Iofthe type mentioned entirely of pipe or B5 tubing, which may be of'the same diameter throughout.

, Another object is to provide with such a 'stove simple and novel means for supporting the stove, said means being adjustable as to V height. I V

, Another object is to provide a combined heating unit and forced draft ventilator, together with sim 1e and novel means for controlling the dra to the ventilator.

' Another object is to provide novel means for supporting a fuel tank upon the upper end of the feed tube of the stove.

With these and other objects in view, my

invention consists in the A construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained,-as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Fig. 1 is a section-a1 view taken through the center of a brooder involving my invention.

2 is a plan view of the stove detached from the brooder.

Fig. '3 is a perspective view of one of the supporting legs of the stove.-

ig. 4 is an enlarged, detail, sectional view through the lower portion of the air inlet flue of the stove.

Fig. 5 is a sectional view through the upper end ofthe air inlet flue illustrating the fuel tank WhlCll is employed when,the drip system is used.

In Fig. 1, I have illustrated a conventional form of brooder having the side walls 10 and ilge roof 11 and having at its top a ventilator Ordinarily the air from the brooder simply passes through anopening in the roof below the ventilator and thence into the atmos here.

y invention aims to utilize the stack 13 of the brooder stove for the purpose of creatmg a forced draft to the ventilator 12.

To this end, the stack 13 is surrounded by asleeve 14, concentrically spaced from the flue 13 and suitably supported in the ventilatlon opening in the roof 11. The ventilator 12 1s supported by means of arms 15 upon the upper end of the sleeve 14.

The stack 13 might-be formed as an integral continuation of the chimney 16 of the stove, or it may be constructed separately and fitted thereover, as shown in Fig. '1.

Upon the chimney 16 is slidably supported 7 a damper 17, which, when raised to the level of the lower end of the sleeve 14, will completely shut off circulation of air there through and which will vary the draft through the sleeve in proportion to its height.

A set screw or the like 18 may be used for 21, 22, 23.and 24:, joined together toform an S shaped construction, the ends of which are joined respectively to the chimney 16 and the inlet flue 19.

A diagonal brace 25 connects the

pipes

16 and 19 and forms a rigid structure of the winding series of pipes.

There are several advantages in the construction just described over the old type of construction of drip feed burner, (which ,comprised a rectangular box, partitioned of to form a winding passage), one of these advantages being the simplicity of construction which is obtained by the use of uniform pipe sections joined together to form the Winding. passageway. Another advantage resides in a marked increase in heat radiation in the present construction as compared with the inclosed box-like structure of prior devices.

Another advantage in the present construction resides in the possibility of'attachment to the

vertical pipes

16 and 19 of a pair of supporting legs, which may be adjusted relative to those pipes, without interfering with the intervening passageway portion of the stove. By slidingly attaching the legs directly to the

pipes

16 and 19, a vertically adjustable supporting structure of the utmost simplicity maybe obtained. Y

The desirability of vertical adjustment of the stove has been recognized prior to my invention. The advantage of the feature resides in the ability to adjust the intensity of heat radiation. from the stove to the chicks below the stove.

In this respect, it will be understood that in the most approved forms of chick hovers,

' not onl the. hm er, but the stove itself should be pre erabi adjustable as to height from the floor of t e brooder.

The supporting structure comprises two independent legs, each having a channel shaped base 26, a pair of

uprights

27 and 28, connected at their lower ends to the base 26 and secured at their upper ends to a split ring 29, adapted to encircle and clamp each of the

upright pipes

16 and 19. A tightening bolt 30, which may be a thumb nut or the like, clamps the ring 29 against its respec-' tive pipe.

'It will now 19, respectively, are received between the

uprights

27 and 28,and that the stove may be lowered until the'horizontal

pipes

20 and 24 rest upon the upper edges of the channels 26. Thus at no time will the stove be allowed to come into contact with the floor of the brooder and the danger of fires will thus be minimized.

It will be noted from an inspection of Fig. 2 that the supporting legs will be secured to their respective pipes so as to extend parallel to and underneath the

pipe portions

21 and 23, overlapping each other somewhat and extending sufficiently on either side of the center line joining the axes of the

pipes

16 and 19 to insure against tipping of the stove.

The upright 28 may be bracedby means of a diagonal brace 31.

The hover 32 is supported upon the pipes be noted that the pipes 16 and (See Figs. 1 and 4.) Vhere the stove is used as a tank heater, the drip system is employed and I provide a readily attachable and de. tachable fuel tank, as shown in Fig. 5.

The fuel tank 34 has secured to its bottom a depending annular collar 35, to which are Socured inwardl extending fingers 36, provided with hoo s 37, adapted to hook ovr the edge of the pipe 19 in order to support the tank thereon in coaxial relation therewith. The collar 35 overlaps the upper end of the pipe 19 so as to guard against sudden drafts affecting the smooth flow of air currents therethrough.

The drip valve which is of an old construction is shown at 38. The fuel is allowed to drip from the valve 38 upon a mass of ashes 39 in the lower end'of the air flue 19. This element is old and does not form a part of my invention. The oil is vaporized as it strikes against the ashes, which are heated by conduction of the heat from the portion of the stove where burning takes place through the walls of the stove.

Nhere the feed. shown in Fig. 1, is used, the oil works its way up through the mass of ashes by capillary action and is vaporized during the process. Combustion commences in the pipe 24 and continues through the

pipes

23, 22, 21 and 20.

It may now be noted that the air within the sleeve 14 will be heated to a higher degree than the air surrounding thesleeve 14 and.

the general atmosphere within the brooder and consequently a column of air which is lighter than the remainder of the air within the brooder will be formed. Thiscolumn of air will ascend, due to its levity and will create a forced draft within the brooder. Creation of this forced draft is accomplished by heat, which would otherwise go up the chimney in the form of waste heat.

The sleeve 14 serves not only to segregate a column of air for super-heating and forced draft but also servesto hold the heat Within the brooder. Instead of having a directavenue of escape through an opening in the roof, the heated air must enter the sleeve at its lower end in order to escape. 'Thus all of the heated air above the lower end of the sleeve is trapped. .In actual o eration the heated air and gases-ascend to t e upper region of the building and then travel downwardly around the sleeve 14, after havin cooled slightly. A continuous circulation of air throughout the entire building is thus assured. v 7

Some changes may be made in the construction and arrangement of the parts of my invention without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their. scope.
