struction and one which will permit the convenient and safe attachment of a feed elevator or spout to the top of the silo.
Other objects of the invention will appear from the following detailed descrip tion.
The invention consists generally in vari ous constructions and combinations, all asv hereinafterdescribed and particularly pointed out in the claims.
In the accompanying drawings forming part of this specification,
Figure 1 is a plan view of a silo roof embodying my invention, a
Figure 2 is a sectional view on the line 22 of Figure l, 1
Figure 3'is a partial plan View showing the preferred manner of securing the inner or upper ends of the roof panels together,
Figure 4 is a sectional view on the line l-4 of Figure 3,. I
Figure 5 is a perspective view of one of the panels of which the roof is composed,

In the drawing, 2 represents the vertical walls of the silo composed of suitable'bloclrs and. encircled .by hoops 3. The roof of the silo is composed of slabs, also of concrete, said slabs being interchangeable and tapered from their outer toward their inner ends and indicated inthe drawings-by reference numeral 4-. Near the outer end of each slab on the underside thereof I provide a shoulder 5 forming with the slab a recess 6 to rest upon the wall of the silo, the shoulder 5 bearing on the inner Specification of Letters Patent. Patented Aug; Applicationfiled October 2, 1919; Serial No.,,327,916.
vertical face of the wall and'preventing outward longitudinal movement of the slab.
At the'apex or center of the roof'l provide. a collar or ring 7 having a flaring flange 8 at its lower edge upon which the inner ends of the slabs are seated. This ring is of'sufi'icient s'izeto provide an opening 9 through which access may be had to 'the'interior' of the silo and a door 10,
for filling purposes h-ingedat 11 to one side of the ring 7 and whenever desired this cover may be tilted backwardly to expose the opening 9. In fillingthe silo, an elevatingmeans is attached to'the top bywhich the ensilage is lifted and discharged into thesilo through the opening in the roof.
The slabs are preferably provided with longitudinal reinforcing rods 12 and near the outer ends of these rods 1 provide up right angle plates 13' having their lower .ends embedded in the slab with holes through which the rods 12 are near the outer and provided inserted, the endsof the rods ends of-the slabs being bent slightly for the purpose of more securely locking them in the concrete. The projecting portion of the plates 13 is provided with ahole 11: and through this hole a rodv 15 is inserted to extend entirely around the silo, forming a railing near the edge, of the roof. This railing forms a convenient attaching means for the elevating 'devicethat is connected with the top of the silo and also formsa very convenient foot rest for a person seated on the roof and pulling or lifting the elevatingdevice to its working position. The rod 15 in effect is a guardrail'to prevent a person from accidentally slipping off the silo roof besides forming a convenient attaching means, as stated; I Y
The inner ends of the slabs are spaced from the ring 7 and the rods vl2 project into this space and around these projecting ends I wrap a wire '16 for the purpose of locking the tapered ends of theslabs togetherand this having been done, I fill the space preferably cone-shaped, is.
between the slabs and the ring 7 with conv crete in plastic form. This concrete flows in under theJends 0f the'slabs and upon becoming hardened forms a tight joint at this point and co-operates with the concrete between the slabs and the ring 7 to hold slabs rigidly in place.
The slabs are preferaby provided with beveled edges 18 which form a ll-shaped recess 19 between them, when assembled in the roof, and into this recess l pour a plastic material 20, which, flowing down to the bot tom of the recess, will seal the joint between the slabs against the entrance of moisture and will present a smooth, finished appearance to the upper surface of the roof. lVhen these slabs are assembled and the roof completed, the collar 7 will be'firmly held between the inner ends of the slabs and the elevating means for filling the silo can be conveniently and safely attached to the roof and a considerable load may be carried by the roof without danger of collapsing.
In assembling the sections of the roof, .i usually place a wooden falseworh and lay the slabs thereon, then insert the ring from the inside of the silo and pour the concrete between it and the ends of the slabs. The falseworl; may then be removed and the sleeves and ring will securely brace each other. The dome or cover 10 is placed on the ring after the roof is completed. lhis is shown clearly in Figure l, where one side of the roof is shown with the cement poured between the ring and the slab while the opposite side is incomplete and the cover is omitted entirely.
I claim as my invention:
1. A building roof having a central ring and a flange radiating therefrom, slabs having their inner ends seated on said flange, reinforcing rods provided longitudinally in said slabs and projecting therefrom into a space provided between said slabs and said ring, and a plastic material for closing the joint between said slabs and ring and said flange.
