Application tiled August 31, 1910. Serial No. 579,957.

To all whom it may concern:

Be it known that we, Finnois il. Tor LEY and l/VILLIAM l?. Snins'rnn, citizens of the United States, residing at Brookville, in the county of Franklin and State of indiana, have invented certain new and useful lmprovements in Sectional Roots for Silos; and we do hereby declare the following` to be a full, clear, and exact description oi the invention, such as will enable others skilled 1n the art to which it appertains to make and use the same. v

This invention relates to improvements in silos, and more particularly to theiroot.

l The object ot' the invention is to provide a simple, economical and durable roof structure, which may be conveniently opened for the introduction of Inaterial rom the top of the silo.

The invention also comprehends improve# ments in the specific details of construction and arrangement of parts which will be hereinafter described, and particularly pointed out in the claim.

In the drawings: Figure l is a sideeleva-- tion of the upper portion of a silo with our improved roof in position. Fig. 2 is a plan view with a port-ion removed to better illustrate the ral'ter construction. Fig; 3 is a plan view of the roof supporting trarne.

`ig. 4 is a view similar to Figl, but showingthe roof sections thrown' open. Fig. 5 is a detail erspective view of one of thereof sections. 6 is a similar view of the roof supporting rame.

The same numerals refer to like parts in all the figures. l indicates a cylindrical or .other shaped silo of any approved construction. Mounted ontop of the silo l is a frame 2 composed of end and side bars 3 and 4:. Each of the said end and side bars is preferably formed of two boards of substantially the same length and securely spiked together as shown vat 5. Each board extends at one end over the adjacent board forming the bar, mortise 6. This construction avoids the necessity of accurate cutting, and also pel'- mits of the use of cheap timber. The noortised ends are fitted i-nto each other and bolts i' fasten them together. The end and side bars 4 and 5, are seured at' their central portions to the top edge of the silo l by lag screws 8, and at the corners bybrackets 9. The brackets are each provided at their-upper end with an outwardly bent portion 10,

to provide al formed with an opening to receive one oi' the screws 7. The lower end of the bracket is bent downwardly to engage the outer surface of the silo, and is formed with openings for the passage of bolts ll. The frame 1s therefore firmly bolted to the silo, and at its corners it is supported by the angularly disposed brackets, which sup )ort the roof structure about. to be describen.

Firrnly fastened tothe side bars 4-4 are ableframes 13, each comprising a base oard lll, two upwardly inclined bars 1.5-

l and an intermediate brace har 16,'suitably secured together and provided with a corrugated sheathing 17. i

The roof proper is composed ,of two or more hinged sections l8-l8 and each section com rises a :frame 19, and a sheathing 20. Eac i frame consists of a series otnpwardly inclined transverse braces 20', corresponding to the inclination of the rafters l5, and formed with a series of mortises 21, in which fit the reduced ends of a series of longitudinally disposed rafters 22. The upper edge oi each iframe is cut at an angle to form a neat and tight joint when the frames are folded. Over this framework the sheathing 20 is fastened. Each section is hinged to the end bars 3, as indicated at 25, a light distance iromthe lower outer edge, the overhanging portion 26 of the section serving to shed the water falling on the roof, and at thesame time acts as an abut-mentto liinit the movement when the'roof sections are thrown open as shown in Fig. 4.

We Vrovide dowel pins 28, at the upper edge ci? one roof section and openings 29, in the edge of the adjacent section, to forno a. firm joint, and alsg form a locking connection between the sections when they are in closed position. Links or'hooks 3l, are pivoted on the inside of each section, and en! gage eyes 32 on the gables, whereb to hold the sections in open position when lling the silo from the top.

A. silo roof constructed as above described, will permit ot' the roof sections being thrown. open on their hin es whereby the silo can be conveniently fille from the top, and when said sections are closed they serve the purpose of an eiiective roof.

`When the sections are thrown sition, as shown in Fig. Il, the overhanglng portions abut against the silo and prevent said sections being swung outwardly too far, and therefore act to brace the parte, which in open powith thehooks or links firmly hold the sections in their open position.

Having thus described our invention what We claim is The combination With a silo, of a horizontelly disposed rectangular-shaped frame upon the upper edge thereof and having its opposite corners projecting beyond the circumference of the said silo. onpositely disposed triangular end frames secured to the upper edges of the ends of the rectangular frame, corrugated, Wind-diverting end closures secured to the end frames, with their opposite edges projecting beyond the said' triangular frames, hinged roof sections 4secured to the opposite sides of the rectangular trane and adapted to rest upon the upper converging sides of the triangular end the roof sections for frames, plates secured to the roof. sections, with the sides overlapping the corrugated end closures, of the rectangular frames, hooks carried by the purpose of supportin said roof sections-in open position, and dowels adapted to engage openings formed in the adjacent edges of the roof sections whereby the same will be held together against displacement, substantially as and for the purposes set forth. f

In testimony whereof We aiiX our signatures in presence of two Witnesses.
