KNOCKDOWN 'IBROODER-CANOPY.

Specification of Letters Patent.

Patented Oct. 4,1921.

Application filed May 14, 1920. Serial No. 381,320.

To all whom it may concern:

Be it known that I, HENRY M. SHEER, a citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Knockdown Brooder-Canopies, of which the following is a specification. I

My invention relates to an improvement in knockdown brooder canopies. I

My construction provides a canopy which is the equal for all practical purposes of the modern type of canopy that is assembled complete in every way at the factory and shipped out in that form. But there are objections to such canopies, because canopies which are fully assembled at the factory and then crated or shipped necessarily occupy a great deal of room, and dealers object to this because of the space required to accommodate them intheir warehouses; and, furthermore, if any part is'darnaged, it means the entire canopy, whereas with the construction which I have devised in case of damage to one or more sections, these sections are capable of being replaced by the user without the damage or loss of the entire canopy.

With my form of brooder canopy, there maybe two or more sections, and these are capable of being closely nested and compactly packed for shipping and storage, and they are so constructed that the usercan easily assemble the parts, or take it apart at will, should occasion require.

My present invention is, therefore, a canopy composed of two or more sheetmetal sections, the edges of which are provided with interlocking seams adapted to fit together, and these are so offset that the upper surface of the sections is substantially flush when the parts are assembled, and by bolting through the seams and pr0- viding braces, a substantial brooder canopy of the knockdown type is provided.

Another feature is a damper at the apex, which is both easily adjustable and removable. Another feature is a suspensory arrangement for a thermometer, which can be easily lifted out of the brooder and examined. Still another feature comprises the removable legs.

In the accompanying drawings:

Figure 1 is a view in perspective;

Fig. 2 is a view of one of the sections;

Fig. 3 is a vertical transverse section;

- Figs. 4 and 5 are details;

Fig. 5 is an enlarged fragmentary sectional view through the top of the canopy.

F g.6 is a view showing a rectangular diaphragm in lieu of the braces.

While the brooder canopy may be made of any number of sections, in the construc tion shown'there are four of these sections, designated by the numeral 1. These are all alike, and they are cut and mitered or interlocked as at 2 and 3, so they will fit together and form the complete canopy when assembled, and these mitered edges 2 and 3 are preferably offset to provide a substantially flush upper or outer surface. The sections are held together 2 and 3, as shown at 4. An opening, 5 is formed at the apex, and a castiron ring 6' with a collar 7 is fitted to and dropped down into this opening 5; by reason of the sections being flush, it fits tightly, asshown in Fig. 5, without the necessity of forming notches and clearance spaces. This ring is preferably held in place by the upper set of the center, so that the upper and smaller.

disk 10 is rotatably mounted on the lower larger disk 11, which constitutes its support. A handle 15 is loosely connected with the upper rotatable disk 10 as a means for turning the disk and regulating the size of the registering openings 12 and 13, or closing them altogether, or as a means for removing the damper when desired to look into the brooder canopy from the top to observe the condition of the burner from beneath.

To give strength to the canopy, the outer edges of the sections are crimped or corrugated as at 16, and braces 17 one for each section, are provided. having their ends held by the bolts A at the seams, thus giving rigidity and strength to the canopy.

The canopy is mounted on legs of any approved construction, as for instance made of wire 18 being as shown in Fig. 5, and held in place by a clip 19 and the bolts 4.

A thermometer 21 is adapted to be by bolting through the mitered or interlocking edges dropped through a hole 22 provided therefor and held by a rod 23, which slides loosely through a disk 21, which closes the hole and supports the thermometer when the latter is lowered. A loop 25 at the top of the rod 23 constitutes a handle and a means for raising and lowering the thermometer when it is to be examined.

Thus I have provided asimple form of brooder, whichcan be produced economically and is capable of being easily knocked down or set up, compactly packed, shipped and stored, and it requires no special skill to set it up. At the same time, the device is light and strong, and the ventilation can be easily. and quickly regulated and the interior inspected without the slightest in-' convenience.

In lieu of the braces, the rectangular diaphragm 27, shown in Fig. 6, is secured at its four corners by seam securing bolts. The

opening-28 at the center is to receive the burner (not shown). The diaphragm serves two functions, namely of the braces, and also increases the heat radiating surface of the canopy.

I claim:

, 1. A knockdown canopy including sec-' tions mitered and interlocked at their edges and'made substantially flush on their outer surfaces, the canopy thus formed having an opening'at the apex, a ring fitted to and dropped into said opening and substantially fitting the surrounding outer surface, and forming a seat at its inner end, and a damper removably supported on said seat.

. 2. A knockdown canopy including sections mitered and interlocked at their edges sections, the side edges of which are interlocked and detachably bolted through, and rigid bracing means extending horizontally within the canopy and secured to each fanshaped section, the canopy and bracing means being open through the center, and means for controlling the outlet of air throiwh the openings in the canopy.

4. r knock-down canopy including a plurality of similarly formed fan-shaped sections crimped only at their outer edges to give them rigidity, means for securing said sections together at their side edges to form a complete canopy, a damper at the apex, means at the bottom for holding the canopy a suitable distance above the ground or floor, and bracing means within the canopy extending horizontally, and detachably connected therewith.

5. A knockdown canopy including a plurality of fan-shaped sections detachably interlocked together at their side edges and having a central opening at the apex when together, a ring having a collar fitted to and dropped down into this opening, said collar having an inwardly extending flange and a damper comprising two disks pivoted together and having registering holes adapted to be seated on the flange for regulating the draft through the opening.

6. The combination with a knockdown canopy made of mitered interlocking sections having an opening at the top and braces extending to the joints between the sections, of a ring secured in the opening, and a damper adjustably and removably supported in the ring.

7. The combination with a knockdown canopy made of mitered interlocking sections having an opening at the top and braces extending to the joints between the sections, of a ring secured in the opening, a damper adjust-ably and removably supported in the ring, legs, clips embracing the legs, and bolts for securing the mitered interlocking edges of the sections together, certain of said bolts utilized for holding the ring, the ends of the braces and the clips for the legs in place.

In testimony whereof I ailix my signature.
