SILO-ROOF.

mosses.

ToaZZ whom it may concern Be it known that I, THoMAs F. MEYER, a citizen of the United States, residing at Bristol, in the county of Kenosha and State of WVisconsin, have invented a new and useful Silo-Roof, of which the following is a specification.

This invention relates to an improved form of silo roof. 1 r

An object of the present invention is to 7 provide a silo roof which may assume a conical form and act in the capacity of a roof or Which may be assembled in the form of a hollow cylinder, in which shape it will act as an extension for the side walls of a silo.

- :A further object'is to provide a silo roof which may assume a cylindrical outline so that the ensilage maybe positioned within the silo and thereabove and allowed to set- -tle after which the roof is folded to its with ensilage.

Nith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the inven tion.

In the drawings accompanying this specification and forming a part thereof, the preferable form of my invention is illusj trated in which :-j-

the roof, holding structure. Fig. 9 is a fragmental View of the roof holding structure at a point near where it joins the silo walls. Fig. 10 illustrates the manner in which a ring is mounted above the upper edge of the silo walls and secured thereto. Fig. 11 is a fragmental View of a modified form.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 represents the cylindrical side walls of a silo fitting over the upper edge of which is a clip member such as illustrated in Fig. 10 and which clip comprises the downwardly extending walls 2 and the crimped or bent portion 3 which is adapted to engage a metallic ring 4 which ring is held concentric of the silo walls a slight distance above the upper extremity of the same.

The metallic ring 4L is adapted to support the silo roof thereon and provides'means whereby the same may be secured to the edges of the silo walls. The roof supporting structure preferably made of iron comprises the central post 5 the lower extremity of which rests against the horizontally X- .tending members 6 the ends of which members are fragmentally illustrated in Fig. 9

of the drawings and comprise a bifurcated portion 7 adapted to engage the metallic ring a. Pivotally secured to the cross mem bers 6 of the roof supporting structure are the upright members 8 which are pivotally secured at theirupper extremities to a col .lar 9, which collar is formed'integral with a sleeve 10 which is adapted to travel over the cylindrical post 5. The sleeve 10 is held in a raised position by a pin-11 or other equivalent means. sleeve 10 and the upright members 8 allows the entire roof supporting structure to be removed from the metallic ring at and to be lifted from the top of the silo previous to the insertion of the ensilage therein. Y

the latter is assembled in the form of a cyl- The construction of the The members which comprise the roof 'proper are formed in a plurality of sections such as illustrated in Figs. 5 and 6 of the The member as illustrated in .Fig. 5' of the drawings is one of a number of members 12 which are substantially trapezoidal in outline and are curved so as; :to conform with the curvature of the silo walls. To the lower extremities of the mem-' bers 12 are secured the members 13, one of which is shown in Fig. 5 with the central portion thereof removed to illustrate the outstanding lugs 14 which are adapted to engage the metallic ring 4: and to secure the member 12 thereto. The outstanding portion 15 is adapted to contact with the side.

walls 1 of the silo and to form an air-tight joint therewith such as illustrated in Fig. 2 of the drawings. A flat metallic ring 16 is secured to the roof supporting members 8 and against which is adapted to contact the upper extremities of the trapezoidal members 12. The remaining portion of the roof is formed by means of the triangular members 17 which are provided with the clownwardly extending portion 18 which is adapted to contact with the upper or smaller ends of the trapezoidal members 12 to forma seal joint therewith. The members 17 are adapted to contact and be supported by the metallic ring or band 16 and the upper ends of the said members 17 meet at the apex of the roof 19, at which point a metallic cone 20 is secured which holds the said members 17 in position and provides an air-tight or seal joint therewith. The members 12 and 17 are formed with grooved edges as illustrated and which provides that the said members will form a structure and will when assembled in position, form an airtight roof.

It will be noted in this connection that other means may be utilized than the tongue and groove to effect a tight joint between the various members 12 and the member 17, as it is thought will be readily appreciated.

When it is desired to fill the silo to which my improved structure has been secured, the cap 20 is removed from the upper portion of the roof and the members 17 removed one by one, after which the members 12 are moved upwardly so as to be disengaged from the adjoining members and the members 12 are then rotated upon the ring 4., being mounted for such rotation by the outstanding lugs 14 illustrated in Fig. 5, until said members lie substantially parallel to the side walls of the silo with which they contact as illustrated in Fig. 3. The members 17 are then positioned between the members 12 with the vertex thereof pointing downward so as to form a circular wall as illustrated in Fig. 3 and which is in fact a continuation of the silo side walls, it being noted that the roof supporting structure which includes the post 5, the cross members 6 and the inclined members 8 may be removed from the silo previous to the positioning of the members 12 and 17 as per Fig. 3. The silo may now be filled and it is noted that a decided in- V 17. The members 12 and 17 are maintained crease in the capacity thereof is obtained and that ensilage may be piled to the top of the extension formed by the members 12 and in this position until such time as the ensilage settles below the upper edge of the walls 1 atwhich time the roof supporting strucring 1 and the band 16 positioned thereon and the members 12 and 17 then returned to their original positions to form a conlcal roof structure, which it is to be' noted will form an air-tight juncture with the side walls of the silo. I I

In order that the roof formed by the members 12 and 17 may be held rigidly in place, a'ring 21 is provided with a turn buckle 22 and the said ring is adapted to fit within suitable grooves 28 formed in the members 12 and 17 as illustrated. In order members 12 and 17 when in a roof forming position, will be air-tight, a band 2 L isflpo+ i sitioned thereon as more clearly shown in Fig.2. In Fig. 1 of the-drawings a dormer window 25 has been illustratedas being secured to one of the members 12 and it is to be understood that such changes may be made within the scope of the presentinvention.

When the silo wall is of considerable thickness, the clip member 2 as illustrated in r Fig. 11 is used in which the metallic ring 4 is set adjacent the inner surface of the silo wall. Attention is also called to the fact that in this modified form the members 12 and 17 rest directly upon the clip member 2' i so as to present a smooth and continuous sur face with the silo wall. The members 13 and the outstanding lugs 14: are removed and a hoop-shaped band 15 inserted in place thereof. Mention is also made ofthe fact that the members 12 and 17 may be made of metal should it be so desired. J

Having thus described the invention what I claim to be new and original with me is 1. A-silo roof comprising trapezoidal and triangular detachable members, adapted to form interchangeably, a conical roof, and a cylindrical wall.

2. The combination with a silo of a roof supporting structure secured thereto, trapetallic ring substantially equal in diameter to the diameter of the siloside wall and detachably supported a slight distance thereabove, a roof supporting structure comprising a central post, horizontal'members se-' cured to said post and engaging and supported by said ring, a sleeve journaled upon said post, and roof supporting members piv-j otally secured to said sleeve and to said' horizontal members. I

The combination with a silo, of a roof supporting structure secured thereto, roof. forming members detachably securedto said and grooves roof supporting structure, the said roof forming members provided With tongues adapted to interlock to form a sealed roof, said members adapted to interengage to form a cylindrical Wall extension for said silo, and means cylindrical Wall extension tion. a a i 5. The combination with a silo, of a metallic ring mounted thereabove trapezoidal members provided with outstanding lugs adapted to rotatably engage said ring, a

for holding said rigidly in posiroof supporting structure detachably secured to said ring and adaptedto hold said trapezoidal members in a roof forming position, triangular members supported by said roof supporting structure abutting the upper extremities of said trapezoidal members and meeting in an apex to thereby form a continuous conical roof, said trapezoidal members adapted to rotate upon said ring to a vertical position, said triangular members adapted to interengage said trapezoidal members to thereby form a cylindrical Wall extension of said silo.

In testimony that I claim the foregoing as my own I have hereto afliXed my signature in the presence of two Witnesses.
