lie it known that leis}: lil. liner, a citizen "rates of .finierica. residing at ecatine. in the county of l rscatine and s out Iowa. has invented ce in new and fill improvements in Vei'itilated Corncribs, of which the following is a specification.

This application is a continuation of my former application, Serial l lo. 331,763 filed October 20. 1919.

My invention relates to corn cribs and more particularly to improvements in constructing cribs whereby ventilated spacer elements are interposed between the staves of the conventional concrete silo.

The object of my invention is in the provision oi a ventilated corn crib by means of interposed spacer elements between the op posed ends of adjacent staves.

Another object of my invention is in the provision of a simple spacer element which may be used in conjunction with the conven tional silo stave to form a ventilated crib.

A further object of my invention is in the particular form of my spacer element which is capable of engaging, in a substantial manner the opposed ends of adjacent staves and at the same time providing suiiicient ventilation therebetween without detracting from the strength of the total structure.

Other objects of my invention will appear in the following; specificationin connection with the annexed drawings in which:

Figure 1, is a fragmentary vertical section of the crib structure showing the actual po.- sitioninp; of the spacer elements.

Figure 2. is a detail vertical section oi one of the spacer elements interposed between adjacent staves.

Figure 3. is a pers 'iective view of the spacer element and Figure t, is a detail horizontal sectional view showing? the engagement of the spacer element with laterally adjacent staves.

In Figure 'l of the drawings. in which I have shown a fragmentary elevation of the corn crib. a base a is shown. This base portion is of concrete. although some other material might well be used inasmuch as there is only the necessity of providing a substantial and level supportfor the stave members. The staves 10 form the major part 01 the wall structure of the crib and are of 331,?53, filed fictober 20, 1919. Thisapplication filed March 27, 1922. Serial No. 547,008.

conventional stave form, being comparai'ely long and narrow and of a thickness to correspond therewith These staves are arranged in superposed courses and in break joint relation as l: have'shown in Figure 1, this structure providing a maximum of emciency not only as to strength but as to ease of construction. As shown in Figure 4 the si es of the staves are concave and convex respectively, with the result that a cylindrical structure may be formed and the staves intained without the use 01 cement. ans for supporting the stave members is vided in the tie rods 11.

The structure I have so far described is merely that of the conventional concrete stave silo but the essence of my invention lies in the following element:

This member has the longitudinal bars 1.2 which in connection with the end or head portions '3 provide the ventilating portions. Projecting); cars 14 on the head portions engage, as shown in the various figures of the drawings not only the opposed ends of adjacent staves but also in a slight degree, laterally adjacent staves. Although my spacer element used in connection with the con ventional silo stave it may be seen that slight indentations 15 and 16 must be made in the adjacent staves to provide engagement portions for the ventilator member.

1 have shown a specific spacer element to be interposed between the stave members but I do not wish to be limited to this particular form inasmuch as other Forms might be used to accomplish the same result.

Although I have referred to the stave members 10 as those used in the conventional silo, l merely make this as a general statement and wish, in the more perfect application for my spacer element, to use it in conjunction with stave members having their opposed ends sloped to an angle of appronh niately forty-five (45} degrees, as shown at 1? and 18 in Figure 2, this construction of the end portions of the stave members pr venting rain partially from beating; through the entilatii portion.

i fhat I. claim is:

j 1 A ventilated corn crib including aplurality oi vertically disposed staves arranged end to end in superposed courses, and grated ventilator members disposed between adjacent staves.

2. A ventilated corn crib including a plurality of vertically disposed stave-s arranged end to end in superposed courses and in break joint relation, means engaging the opposed ends of related staves and disposed therebetween in such manner as to form a ventilating opening therein and supporting means encircling the crib.

3. A ventilated corn crib including a plurality of vertically disposed staves arranged end to end in'superposed courses, said staves having an elongated comparatively thin and narrow body with recesses formed in the ends thereof, and ventilating members disposed between the opposed ends of adjacent staves and engaging said recesses.

4. A ventilated corn crib including a plu- JOHN H. IREY.
