VENTILATING CUZPOLA.

Application filed August 1'7, 1921. Serial No. 492,953.

To all whom it may concern:

Be it known that I, HERMAN citizen of the United Minneapolis, Minnesota, but now SILVER, a

formerly of rcsi ding States,

5 at Fairlield, in the county of Jefferson and State of Iowa, have inv ful Improvement which the following is My invention relates in Ventilating Cupolas,

ented a new and useof a specification.

to cupolas designed to be placed on buildings, such as barns and the like,

to promote ventilation therein, to add to the general appearance of the and building, and it consists of an improvement in the details of cons truction, whereby a more substantial construction will be ob tained, and the cupol a, which should be mostly sheet metal, will be more securely anchored to placed. Also, in other the building upon. which it is details of construction which will be hereafter explained and set forth in the claims.

In the accompanying drawings forming a part of this specificat ion, Fig. l is a view,

is an enlarged vertical of Fig. 1, looking in section on line 22 the direction of the arrow, and the cut away portion of Fig. 1

being shown to make this figure complete.

9, and 10 are detail views which will be hereafter explained.

Referring to the drawings,

the base of the cupola,

the lower portions of the inner band; D an outer The base is preferably made for the cupola;

A represents the upper and B cupola flue; C an band, and E a cap rectangular with the lower edges outwardly flared, the upper portion of the flue section cylindrical, the cap conical, and the lower ortion of theflue section tapered with its ower edges rectangular and adapted to fit over the upper edges upper edge cylindrical the lower edge of t flue section. As menu of the base and its and fitting under no upper portion of the factured, the cupola consists of three separate sections towit: 1st, the base A with the frame timbers ll and cornice G; 2nd, the flue section con sisting of the upper and lower portions B and B, which are preferably joined together as hereafter explained, and having the inner band C attached to the upper edge of the flue; and 3rd, the top portion having the outer band I) and cap E with their attachments.

The sections are all turned upside down in nesting as shown in l. First, the base A and then the part B of the flue portion is placed in the base with the inner band C resting at certain points upon the frame timbers l5. Lastly the cap E with its spire H reaching downward into the line section B, and the outer band D resting at certain points on the lower edge, (but now the upper edge) of the flue section B. The contacting edges of the flue portion B being rectangular while the contacting edge of the outer band D is cylindrical, it will be readily understood that they will cross each other at points near the corners of the portion B and will come in contact at these points, the diagonal dimensions of the section 13 being greater than the diameter of the band D.

When thus nested, the portions of the cupola will be in the form of a substantially rectangular shaped package, and the most delicate parts will be protected and can be securely crated for shipment, as shown in Fig. 5. As will be seen, when. the sections are nested, the circumference of the outer band D will be substantially in vertical alignment with the central portions of the rectangular flanged edges l. and the cornice G, and will all be in direct contact with the central. crating boards which will. hold all the parts securely in place, and the nested sections can be entirely surrounded and held in place by a rectangular shaped crating, as shown in Fig. 5.

In placing the cupola on the building the base A. is first set in place. Its lower edges will have to be cut to fit thepitch of the roof J, which should be cutaway inside of the cupola, leaving the rafters K intact. The flanges l are designed to make a better connection with the roof and are preferably connected thereto by nails or screws. a, as shown in Fig. 1. In cutting away the edges ofthe base to lit the pitch of the roof,

. base, through which enough extra metal should be left to form this flange all the way around. The base being fitted to the roof and secured thereto by the nails a, the next thing is to anchor it to the roof timbers.

For this purpose, metallic plates L are secured to the inner sides of the frame timbers F, preferably on opposite sides of the threaded bolts having threaded nuts on the-irlower ends M are passed down through a timber or timbers in the roof of the building. Where a ridge pole N is used, all that is necessary is to bore holes through the ridge pole directly elow the plates L and pass the bolts M through these holes. lVith a ridge pole anchor bolts shorter than those shown in the drawings may be used.

lVhen there is no ridge pole, collar beams may be secured to the rafters and if near enough to a vertical position under the plates L, a hole may be bored through each collar beam and the bolts passed through them. If the collar beams are not in the proper positions, a header P may be placed between them directly under the plates L and the bolts M may be passed through properly located holes in the header. In Fig. 1, both the ridge pole N and the header P are shown, although only one is generally necessary. In any event it is advantageous to use the collar beams, because in a storm they will hold the rafters more securely together and this will make a more reliable anchon Fig. 3 shows a modified In this case the sides of the base having the timbers F on'which the plates L are placed, are set on opposite sides of the peak of the roof instead of crossing it at right angles as shown .in Figs. 1 and 2, andheaders Q are placed between the rafters K immediately below the plates L and through these headers the anchor bolts Mare passed. This plan will require longer anchor bolts than the plans shown in Figs. 1 and 2. I show different plans to accommodate different conditions, and users can take their choice.

The base A being placed in posit-ion and securely anchored, the next thing is to attach the flue sect-ion consisting of the portions B and B. The lower edge of the'portion B is made to fit over the upper rectan gular edge of the base immediately above the cornice G, and it may be secured thereto by a series of nails 6 driven through holes in its lower edges into the timbers F. This will hold the section securely in place and will form a rain-tight joint.

The next and final step is to connect to the upper portion of the flue section the remaining section consisting of the outer band D and the cap E and their-attachments. The outer band D and the cap E are connected together by a series of circumferentially form of anchor.

spaced apart braces R having downwardly inclined perforated ends (shown upwardly inclined or inverted in F ig. 4), and all that is necessary to make the connection is to join these perforated ends to the upper edge of the inner band C, or to the means connecting the inner band to the flue section B by a se ries of bolts (Z. lVhen this is done the different parts of the cupola will be in operative position as shown in Fig. 1.

It is advisable to use a screen in the space between the inner band and the cap to keep birds, bats and the like out of the flue. The side portions of this screen are indicated by S, the central portion being broken away to give a better view of the parts behind. it. Formerly this screen was connected to the upper edge of the flue section B and from there extended perpendicularly to inner portions of the cap, as shown by my Patent #1,- 312,586, Aug. 12, 1919, Reissue #15223, Nov. 8, 1921, of which the structure herein disclosed is designed to be an improvement. The former arrangement permitted birds and bats to roost on the sheltered upper edge of the inner band and to drop pieces of wool. moss and other debris in the space between the inner band and the flue, and even to build nests therein, so that in time the space was liable to become entirely closed.

To remedy this defect I attach the up per and lower edges of the screen to the adjacent edges of the cap and the inner band by the lower bolts 6 which connect the lower edge of the cap to the upper ends of the braces R. and by the upper bolts d which connect the lower ends of the braces R to the upper edge of the inner band C. or to the outer upper edges of the devices connecting the inner bend to the flue.

All that is necessary to make the connection is to pass a mesh of the screen over the point of the adjacent bolt. the burr being removed, and then place a washer a over the point of the bolt large enough in circumference to hold the mesh, and then place the burr and turn it down to hold the washer, as shown in F 7, which is an enlarged section of the left side of Fig. 1, showing a portion of the screen. This will effectually protect the inner band and the only additional ex pense will be the cost of the washers which will be much less than that required to at tach the screen to the flue in the former way.

As before stated it is preferable to make the base A rectangular. When this is done the preferable way to join the vertically disposed edges of the four sides together. is to form on their adjacent edges outwardly and backwardly disposed hook-shaped flanges, as shown in Fig. 8, A representing transverse sections of adjoining portions of the two sides of the base. Then use a corner binder T which is bent at substantially right angles longitudinally near its center, and has on its opposite edges inwardly disposed hook shaped flanges U as shown separately in Fig. 9. By placing the edges of the sides A together the binder T can be slipped endwise over their adjacent edges and its inwardly disposed hook shaped flanges U will slide below and catch under the outwardly disposed hook shaped flanges of the sides A. After being properly adjusted the hook shaped interlocking flanges will make solid reliable connections Without any additional fastenings.

As already stated, the upper and lower portions B and B of the flue section are preferably connected together in the factory and before nesting or crating and shipping. In order to obtain the most substantial water-proof joint between them I bend the lower edge of the upper portion inwardly and upwardly back on itself, and then bend the edge downwardly beyond the backwarclly bent portion, leaving a narrow space between the edge and the bent portion. The upper edge of the part B is then inserted in this space and after the parts are brought close together they are held in place by a series of rivets 00, passed through them below the bend. This makes an exceedingly strong rain-tight joint between the portions B and B, as most plainly shown in Fig. 10.

It is preferable that a pair of anchor bolts passed through anchor plates secured to the frame timbers on opposite sides of the base be used, but if desired, a single bolt passed through an anchor plate secured to a frame timber in the base may be used and will answer the purpose of anchoring the cupola to the roof of the building. The threads on the lower end of the anchor bolt or bolts should be long enough to permit the nut or nuts to be drawn up tightly against the lower edge of the timbers O, P or Q, if they should be set a little too close to the plate L.

There may also be other variations in the details of construction without departing from the spirit of my invention.

What I claim is:

1. In ventilating cupolas having a base section, a rectangular shaped frame on the inside of said section, metallic plates secured to the inner sides of the timbers of said frame on opposite sides thereof, and threaded bolts provided with threaded nuts passed vertically through said plates, whereby when the cupola is placed on a building, the bolts may be passed down through a timber or timbers in the building, and the cupola may thereby be adjustably anchored to the building by turning up the nuts on the bolts.

2. A ventilating cupola having a flue section, a band secured to the outer upper edge of the flue so as to leave a space between the band and the flue, a top section having a cap with its edges located a distance above the band, means to connect the cap to the band leaving a space between them, and a screen inserted in the space between the cap and the band, one edge of the screen being secured to the lower edge of the cap and its other edge secured to the upper edge of the band.

3. A ventilating cupola having a flue section, a band secured to the outer upper edge of the flue so as to leave a space between the band and the flue, a top section having a cap with its edges located a distance above the band, a series of oircumferentially spaced apart braces to connect the cap to the band and leave a space between them, and a screen having its upper edge secured to the upper edge of the cap and its lower edge secured to the upper edge of the band by means of the fastenings which secure the braces to the cap and the band.
