Cement Corncribs, of which the following is a specification.

My invention relates to that class of staves which are to be used in corn cribs or other structures requiring'ventilation.

The object of my present invention is to provide a ventilated stave which will exclude the rain and snow and destructive rodents, but which will be exceptionally strong by reason of its peculiar construction, inasmuch as it has strengthening Webs extending both vertically and horizontally intermediate the ventilating apertures.

My means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawings which are hereunto annexed and are a part of this specification, in which Fig. 1 is a side elevation of a stave con structed in accordance with my improvement. Fig. 2 is an end elevation partly in section, of the same.

Fig. 3 is a fragmentary portion of a wall of a corn crib constructed with this form of my invention.

F 4 is a fragmentary detail view of a stave having a modified form of aperture.

Fig. 5 is a sectional view of the same.

Fig. 6 is a fragmentary detail view of a portion of a wall of a corn crib with this form of aperture.

Fig. 7 shows a stave having a modified 40 form of aperture.

Fig. 8 is a sectional view of the said fragmentary portion of a stave.

' Similar reference numerals refer to similar parts throughout the entire description. As shown in the drawings, the stave 1 is provided with a plurality of elongated apertures 2 which are located in spaced rela-- tion to each other, the spacing being accomplished by horizontal webs 3 and vertical ribs 4. The walls of these webs where they meet the apertures, are tapered as clearly seen in the sectional view. This construction enables the manufacture of a stave in which the apertures can approach the edges 5 and 6 closer than they can in a construction in which only the horizontal formed in the stave 14% are square.

ribs are employed. This enables one to provide the increasedstrength afiorded by the vertical ribs 4: without sacrificing the necessary radiation to ventilate the crib properly. i I

As shown in the drawings, the stave is provided with grooves 7 in one end and a convex portion 8 at the otherend, a similar construction being employed on the vertical edges 5 and 6. In Fig. 3 I have shown a view of a portion of the wall or" the silo,the

staves being held in position'by tightening bands 9 and 10 which may be drawn together in any suitable or convenient manner so as to hold the staves securely in position.

In the modified form shown in Fig. i, the apertures 11 shown in the stave 12 are round but they also are tapered as clearly seen in Fig. 5. In Fig. 7 the apertures 13 It will be apparent that these variations are merely such as may be desired to suit or meet particular conditions or localities in which the crib is being erected, but that they are entirely within the scope of my invention as described in the hereinafter contained claims.

In this form of stave, I have shown a broken joint of the end across which the connecting bands 9 and 10 pass, as it will be obvious that no particular form of construction, as far as the edges of the stave are concerned, is essential to the successful opera tion of my invention, it being designed to permit of the construction of a very large stave which is capable of withstanding extraordinarily heavy pressure without collapsing, and yet insuring sufficient ventilation to accomplish the desired result.

I do not here claim anything shown, described or claimed in United States Letters Patent No. 1,390,994 granted September 20,

1921 on my copending application No.

Having described my invention what I regard'as new and desire to secure by Letters Patent is:

1. In a cement stave for corn cribs, having a plurality of apertures therein, a vertical and longitudinal'web intermediate said apertures, a portion of which web forms a wall of said apertures, the walls of the apertures tapering from one surface to the other so that the opening at one surface of the stave is smaller than the opening at the other.

2. In a cement stave for corn cribs having a plurality of square apertures therein, a vertical and longitudinal web intermediate said apertures, a portion of which web forms a Wall of said apertures, the walls of the apertures tapering from one surface to-the other so that the opening. at one surface of the stave is smaller than the opening at the other.

3. In a cement stave for corn cribs having a plurality of rectangular apertures therein, a vertical and longitudinal web inter mediate said apertures, a portion ot which web forms a Wall of said apertures the walls of the apertures tapering from one surface to the other so that the opening at one surface of the stave is smaller than the opening at the other. I

4. In a cement stave comprising a slabot' concrete having a plurality of apertures separated vertically and longitudinally by webs terminating in the outer solid walls of the stave said webs being strength giving members to the stave the upper walls of the longitudinal webs slanting downwardly and outwardly being means to shed rain or the like.

5. A cement stave comprising a slab of concrete having aplurality of apertures HARRY BERNARD J ONES.
