Abstract: A block for use in constructing a retaining wall having a bottom with a non-planar portion which creates a gap between the bottom surface and the top surface of a lower course of similar blocks when the block is placed thereon is herein disclosed. The non-planar portion permits the block to rest on a lower course of blocks and provides a space where small amounts of rubble and dirt may exist without interfering with the stacking of the blocks. The non-planar portion of the block reduces the unit weight of the block without significantly affecting the structural integrity of the block. The block's bottom surface may further comprise a plurality of grooves and a gutter constructed and arranged with respect to the non-planar portion so as to define a bearing surface therebetween.

Abstract: A wall structure (10, 110) and method of construction. The wall structure (10, 110) comprises a plurality of preformed, lightweight blocks (12, 112) supported and interconnected by a plurality of elongated, vertically oriented, collateral support beams (16, 116). Preferably, the support beams (16, 116) are operatively connected to an appropriate substructure (62, 100) and the lightweight blocks (12, 112) are operatively connected to the support beams (16, 116). The blocks (12, 112) and support beams (16, 116) are configured so that when they are connected to each other, a space is formed between the wall structure (10, 110) and the substructure (62, 100). Thus, an assembled wall structure (10) may be setoff from a substructure and the substructure (62, 100) may be used for other purposes.

Abstract: A retaining wall comprising a series of differently sized, pre-formed horizontal and vertical blocks. Each block includes a projection and a recess, with the projection and recess arranged and configured so that each projection effectively engages a recess in an adjacent course to operatively connect adjacent courses together. The horizontal, blocks are formed in incremental thicknesses and may be stacked in various combinations equivalent to the height of the vertical, blocks. The location of the abutment member relative to the block may be varied to enable adjacent courses to be coplanar or tiered in a variety of predetermined offset distances.

Abstract: A fastening element for operatively connecting masonry units together in a fixed relation. The fastening element comprises a body with a web having opposing surfaces, and a plurality of projections that extend in a generally perpendicular direction therefrom. The projections are spaced apart from each other and configured to engage portions of masonry units therebetween in a constrained relation. The fastening element permits two, three, or four masonry units to be operatively connected together in variety of configurations without the use of mortar.

Abstract: A block for use in constructing a retaining wall having a bottom with a non-planar portion which creates a gap between the bottom surface and the top surface of a lower course of similar blocks when the block is placed thereon. This gap assists the block in resting on the lower course of blocks in a stable, level manner by providing a space where small amounts of rubble and dirt may exist without interfering with the stacking of the blocks. The non-planar, preferably concave, portion is also advantageous in that it reduces the unit weight of the block without significantly affecting the structural integrity of the block. Preferably, the block's bottom surface further comprises a plurality of grooves which further reduce the weight of the block and provide additional clearance in the gap for larger stones.

Abstract: A mortarless wall structure comprising a plurality of preformed, stackable blocks with the blocks operatively connected to each other by a plurality of elongated, vertically oriented, support beams. The blocks may include one or more channels that are configured and arranged to intercept moisture traversing from the front surface toward the rear face of the block, and to direct the moisture in a predetermined direction that does not intersect the rear face. The wall may be freestanding or operatively connected to a suitable support structure by one or more brackets. Each bracket includes a support beam engaging portion and a structure engaging portion, and is configured and arranged to allow constrained movement of the support beam in a predetermined direction relative to the support structure. When used in conjunction with a support structure, the wall may be provided with a sealing element that prevents moisture and debris from being introduced between the wall and the support structure.

Abstract: A block for use in constructing a retaining wall having a bottom with a non-planar portion which creates a gap between the bottom surface and the top surface of a lower course of similar blocks when the block is placed thereon. Preferably, the block's bottom surface further comprises a plurality of grooves. It is envisioned that these grooves be “V” shaped, thereby having angled walls which act to funnel the larger stones into an area of adequate clearance when the block is being placed on a lower course of similar blocks.

Abstract: A retaining wall made up of a plurality of blocks shaped to prevent the escape of material used to fill the cavities of the wall while allowing dissipation of pressures exerted on the wall by the retained earth and a method of constructing the wall taking advantage of the continuous, uninterrupted vertical cavities formed by the unique shape of the blocks. The shape of the blocks comprises a front portion interconnected to a rear portion which has ears on opposite sides which cooperate on adjacent blocks to create a tortuous path into a space created between two adjacent blocks. In a preferred embodiment the rear portion further comprises a cavity which, when pyramidally placed on top of two adjacent blocks, forms a continuous, uninterrupted vertical column which significantly increases the weight and strength of the wall when filled with a particulate filling material.

Abstract: A retaining wall block is provided which comprises a forward, face portion and a tail portion spaced rearwardly of said face portion and extending generally parallel thereto, said face portion and said tail portion being connected by a central web. A downwardly depending abutment member is formed on the bottom of said face portion to serve as a spacing mechanism for offsetting successive courses of block, thereby imparting a uniform backslope to the retaining wall. The block is designed in such a fashion that portions of the spacing mechanism may be easily removed or modified so as to permit different angles of backslope.

Abstract: A silo is provided with a thickened section along one portion of its circumference and located therein is a passage extending from top to bottom of the silo. This passage opens into the silo by means of an unobstructed opening which also runs from top to bottom of the silo. This opening may be covered by a series of doors which may be automatically opened and closed in conjunction with the silo unloading operation.

Abstract: An agricultural silo comprising a plurality of vertically spaced apart silage discharge orifices includes a double passage chute overlying the orifices. The chute includes a first passage permitting unobstructed operator access and a separate silage discharge passage which confines the silage during the unloading operation. A dormer door provided in the silo top may be opened to discharge silage therethrough into the silage discharge passage. When opened the door vents the silo and when closed the door prevents material from entering the climbing and discharge chute during silo filling and prevents updrafts in the chute during unloading. A frame affixed in a dormer space at the top of the silo and chute defines a dormer opening of substantially the same size as the discharge orifices for snug mounting of an unloading transfer conduit therein.
