2 Sheets-Sheet 2 BY Mv ATTORNEY Patented Dec. 1, 1931 LEVI n. HOUGHTALING, or READING, PENNSYLVANIA ,SILO STAVE Application filed September 30, 1930. Serial No. 485,496.

' This invention relates to a stave construction designed particularly for use in constructing silos of the type disclosed in my United States Patent No. 1,750,600, although I do not limit myself to its use therein.

- Anobject of this invention is to provide a stave of a simple but durable structure, and

. having means for its quick assembly into its final position.

A further object is to avoid the necessity of costly bricklaying in'the construction of silos, the staves herein-described and claimed being easily assembled by one having little or no experience.

'15 Still a further object of this invention is to rovide a silo stave comprising a concrete body having a reinforcing framework embedded therein, said framework comprising means whereby said stave may be interlocked with adjacent staves when set up in a building structure.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly ointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a perspective view of a silo 1 constructed in accordance with my invention,

Figure 2 is a perspective view of one of my improved staves, Figure 3 is a side elevation of a row of my ci-mproved'staves connected together to form,

'35 for example, the wall of a silo suoh'as is shown in Figure 1, i

Figure 4 is a longitudinal sectional view, partly broken away, of a pair of my staves in assembled position, and portions of abut- 4 ting staves,

Figure 5 is a partial sectional view taken on line 55 of Figure 4,

Figure 6 is a perspective view of a horizontal reinforcing member hereinafter more fully described, and

Figure? is a fragmentary perspective view showing the reinforcing elements.

Referring more particularly to the draw ings, 10 indicates the body of a stave. It will r be seen that the outer or exposed face 11 of the stave has a projecting edge 12 which extends lower than its adjacent edge 13. It will further be seen that the inner face 1 1 of the stave has a proj ectingedge 15 which extends higher than its adjacent edge 16. Vertically disposed and permanently embedded in; the stave is a pair of tubular steel reinforcing members '17. These members 17 extend from a pair of cone-shaped openings 18 in the edge 16 through the edge 12, and have free ends 19 at their lower extremities. The free ends 19, it will be seen, are adapted to fit into the cone-shaped openings 18 of the subjacent stave. Also permanently embedded in the body'of the stave and spot-welded to the members 17 is a series of horizontal reinforcing members 20, of which I have shown three inmy preferred form.

Locking sockets 21 are permanently affixed to one end of the members 20. 7,0

These members 20 extend from the socket 21 and protrude from the other side of the stave. The protruding ends are formed into keys 22. The locking sockets 21 are adapted to receive the keys 22 of the adjacent stave,

when assembled. It will be noted that the hollow members 17 are adapted to act as drains for any seepage that may accumulate between a stave and its overlying stave, thus forming a continuous vertical drainage sysso tem forany structure that might be erected by the use of said staves. v

, WVhen a circular structure, such as that shown in Figure 1 is built with my improved staves, the completed structure is braced against outward strain by encircling steel bands, 23, which are more particularly described in my above-mentioned patent.

It will be seen from the above that my stave may be quickly assembled into a wall by first, forming a bottom row of staves, and there assembling the remainder of the staves until a desired height is reached. 7

This is done by attaching the free ends 19 in any suitable manner to a concrete base, then. inserting the keys 21 of the adjacent stave in the sockets 21 of the first stave. After the bottom row has thus been formed, all that is necessary is the placing of the free ends 19 in the cone-shaped openings of the underlying stave, at the same time placing the keys 22in the sockets 21 of the'adjacent stave. The hollow tubes together with the cone-shaped openings 18 will serve to drain off any accumulation of liquid which may collect between any stave and its overlying stave.

,. The horizontal bars 20, together with the I vertical bars 17, by means of the welded joint securing them together, form 'a rigidrein forcing framework for the stave o rb'lock.

In addition to the reinforcing feature, .t hi s framework'provides the means whereby the interlock is formed with adj acent staves, thus 1 having theadvantage of p rforming a double funetlon in this organization. 4
