WALL STRUCTURE FOR CORN-CRIBS AND THE LIKE.

To all whom it may concern:

Be it known that I, JOHN H. IREY, a citizen of the United States, residing at West Liberty, in the county of Muscatine and State of Iowa, have invented certain new and useful Improvements in Wall Structures for Corn-Cribs and the like, of which the following is a specification.

The invention has for an object to enable the construction of ventilated walls such as are required for corn cribs by the use of stock material. such as is employed in the construction of concrete silos, and other wall constructions. It is a particular object to enable the construction of a corn crib with suitably ventilated walls, while at the same time there will be a minimum liability of ingress of water during storms.

A further object is to provide an improve ment in a specific article of manufacture adapted to enable the construction of ventilated walls from ordinary blocks, bricks and the like without requiring the cutting of the wall nor the building of special openings therein requiring a disturbance of the orderly formation of courses as ordinarily followed in the construction of a solid wall.

Additional objects, advantages and features of invention will appear from the construction, arrangement and combination of parts hereinafter set forth comprising one of the possible embodiments of my invention, an a proximate representation thereof being ma e in the accompanying drawings, wherein Figure 1 is a fragmentary elevational view of a section of a concrete corn crib wall embodying my invention,

Fig. 2 is a fragmentary vertical cross section thereof,

Fig. 3 is a detail of the ventilating spacer unit interposed between the superposed blocks of the wall.

Fig. 4 is a fragmentary perspective of a modification of the spacer element.

Fig. 5 is a fragmentary end view of a spacer with more than two bars. Fig. 6 is a fragmentary horizontal section of wall showing the angular relation between the stave units, and the relation between the masonry units and my spacer.

There is illustrated a section of wall 10 which may be used as a corn-crib wall or as a bin wall for other uses. In order to effect the formation of ventilating openings in the wall without changing the orderly form of Specification of Letters Patent. Patent d J 21 192 Application filed October 6, 1919.

Serial No. 328,740.

the courses of blocks or other building units employed, I have provided a spacer plate and guard 11, illustrated in Fig. 3 which may beset in place upon the'upper surface of certain of the building units and other units superposedthereon, bywhich the latter are held spaced above the lower ones, the plate 1l thus becoming or taking the place of building units or parts thereof. Preferably in the construction of grain cribs, I use blocks termed stave elements which for the most part are formed with outwardly incl ned upper and lower edges 12 and 13, in Fig. 2. The bottom and top blocks, however, are formed with horizontal edge faces at one end and sloping faces at the other. The blocks having such formation may be termed starting and finishing blocks,and are formed in two'sizes, one being longer than the other, as indicated at 17 and 18 in Fig.

1 so that when blocks of uniform size are superposed thereon in vertical series or coursesthey will break omts uniformlyas shown in this view. In its preferred form,

my spacer device is constructed as shown in Fig. 3, being a stamping of thick sheet metal or a casting, comprising head portions 19 at each end connected by a plurality of narrow bars 20 in sufiicient number and spaced close enough together to prevent passage therebe tween of small rodents and vermin such as m ce. The head portions 19 are provided with projecting ears 21, at top and bottom adapted to be set in notches which may be formed or cut in the opposed faces of super posed stave elements as shown in Fig. 2. This device may, of course, also be used with stave elements having horizontal upper and lower faces, or may be formed in a size corresponding to that of an ordinary brick, and interposed between vertically adjacent bricks in a course of a wall, as will be understood from the disclosure.

In the use of this invention, the stave elements are cast in the form indicated, and if not provided with the notches 22 adapted to receive the cars 21 at each side, they may be notched with a chisel or other suitable tool as they are put in place. The first course of stave elements 17 and 18 alternately are put in-place and secured by a hoop element p 11 interposed as shown in Fig. 2, and a second hoop element 23 is thenengaged around the upper ends of the elements 17 and the lower parts of the elements 24.

customarily, the stave elements used in constructing circular cribs and bins have their vertical edge portions concave atone side and convex at the other, as shown in Fig. .6, so that they interlock to a certain extent, thus facilitating the use of my spacingplate and preventing liabilityotlateral displacement of the upper stave elements when supported upon my plates 11. After the weight of the upper elements is largely taken up or carried by the cement between laterally adjacent stave elements.

If desired, the spacer device maybe formed shown. in Fig. 4, wherein a plate 11 is provided similar to the one first described with the'exception. that the head portions 19 are provided at'their upper and lower parts with oppositely extended flanges 27 by which the device will be self-supporting upon a horizontal surface, and will also support a superposed buildingunlt thereon in such a manner that 1t Wlll IlOt fall. to one sideior the other, while a wall is in course of erection.

It has been found that with this construction a crib can be built very quickly, less time having been required to construct a crib of a given capacity than by the use of any other known building material with workmen operating at ordinary speed.

With building blocks of ordinary thick ness, the sloping of the vertically adjacent faces-of the stave elements at an angle of about 45 degrees to the horizontal locates the inner upper edge portion of the lower'stave unit well above the outer lower edge of the upper stave element, (see Fig. 2) making it impossiblefor ordinary rain to beat in upon the contents of the crib. V p

In Fig. 5 there is illustrated the possibility of forming the spacers with a greater number of connectingbars 20 corresponding to those 20 before mentioned.

lVha-t is claimed is: V p

' 1. course building element for a directly ventilated wall comprising head portions'and connecting air admitting vermin guard parts therebetween, said head portions having parts projected above and below said connecting portions.

2. A masonry course unit comprising head parts andiconnecting air'admitting vermin guard parts, said headhaving broad upper and lower parts to afford a wide bearingon supporting and superposed masonry.

In testimony whereof I have aflixed my signature in presence of two witnesses.
