VENTILATED SILO.

Specification of Letters Patent. Patented Aug, 24, 1920,

Application filed April 28, 1919. Serial No. 293,180. H

To all whom it may concern.-

Be it known that I. Ronnn'r I'TARTENBER- GER, citizen of the United States, residing at Sheboygan Falls, in the county of Sheboygan and State of Wisconsin, have invented certain new and useful Improvements in Ventilated Silos; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to. make and use the same.

My invention relates to improvements in ventilated silos, such as that shown by my United States Patent 1,220,106, of March 20, 1917, the present improvements residing more particularly in a novel form of silo ring and in the association of the several rings with the vertical studs which extend between them, the object being to simplifyand cheapen the construction of the patent above mentioned, without sacrificing any advantages thereof, and to provide a frame structure which can be compactly shipped in short sections.

With the foregoing in view, the invention resides in the novel construction and arrangement of parts hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawing.

Figure 1 is a side elevation of a silo with parts broken away and in section.

Fig. 2 is a horizontal sectional view out above one of the silo rings.

Fi 3 and 4 are vertical sections at right angles to each other, taken on the planes of the lines 3-8 and 14 of Fig. 2.

Fig. 5 is a perspective view of a portion of the silo frame with parts thereof disconnected.

In the drawing, the numeral 1 designates a suitable base of concrete or the like upon which the silo is constructed, said silo con sisting briefly of superimposed horizontal rings 2, vertical studs 3 extending between said rings, inner and outer staves 4 and 5 respectively and a suitable roof 6. The staves 4 and 5 are nailed to the silo rings 2 and these rings are constructed and associated with the studs 3 in novel manner.

Each ring 2 is formed of a plurality of arcuate sections 7 sawed from wood, the ends of said sections being in abutting relation and having registering notches 8 which form mortises to receive tenons 9 on the ends of the studs 3. The several sections 7 of each ring are secured together by plates 10 of oak or other suitable material and these plates are provided. with mortises 11 alined with the registering notches 8. Spikes or. other preferred fasteners 12 are employed for securing the plates 10 to the sections 7 and said plates may either be located at both the upper and lower sides of the rings 2 or only at one side thereof, as desired. I is preferred however to provide each ring with upper and lower plates as shown.

By providing the notches 8 in the ends of the ring sections 7, connecting the ends of the sections by the plates 10, and securing the tenons 9 in the mortises, an extremely eflicient structure is provided, yet one which may be easily sawed at the mill and assem bled after shipment. The plates 10 prevent spreading of the sections 7, the mortises 9 and the notches 8 prevent relative lateral movement of said sections, and in addition,

the mortise and tenon joint forms an effective anchorage for the studs 3, and it will he observed that due to the weight of the frame structure, the studs 3 will exert such downwardpressure as to prevent any possibility of the plates 10 becoming loosened from the ring sections 7. The adjacent ends of the tenon 9 of course are spaced slightly in order that contact of the studs 3 with the plates 10 shall be unimpaired.

The lowermost ring 2 is secured by suitable anchors 13 to the base 1 and all. of the other rings are provided with openings 14; which permit free circulation of air from one end of the silo to the other, suitable provision being provided for allowing the entrance and escape of air as in the patent above referred to.

Since excellent results are obtainable when using the exact details shown and described, they may well. be followed, but within the scope of the invention as claimed, numerous minor changes may well be made as occasion may dictate.

I claim:

A silo structure comprising a plurality of vertically spaced rings each formed of short arcuate sections abutting at their ends and provided in such ends with registering notches jointly forming mortises, horizontal connecting plates secured to the upper and lower sides of said ring sections and extending over the joints between them, said plates having central mortises alined with those aforesaid, and short studs of a length to extend between the adjacent rings, said studs being reduced at their ends to form tenons and shoulders at the inner ends thereof, said tenons being snugly received in said alined mortises and said shoulders resting tightly against said connecting plates, the tenons in each mortise being spaced slightly apart at their adjacent ends to permit the 10 shoulders of said studs to 'bear tightly against said connecting platesJ In testimony whereof I have hereunto set my hand;
