Abstract: An anchor rod for supporting walls, bulkheads and the like, comprises: an anchoring body to be cemented to the ground, at the bottom of a hole for the rod, by burying it into a casting of cement mixture, forming therewith the anchor bulb of the rod; traction cables connecting said anchoring body to a head-piece being fixed to the wall or like to be supported; two pipes containing and protecting said cables inside said hole, the first of said pipes carrying centering members, distributed throughout its length, and an inflatable plugging sleeve close to its end opposite to the head-piece, while the second pipe is telescoped into the first one, in correspondence of the end; and one pipe for feeding said cement mixture to form said bulb. The anchoring body consists of a frustoconical element, connected with its minor base to the end of said second pipe and housing, at its major outer base, a connection plate for the traction cables, being crossed by the pipe for feeding the cement mixture.

Abstract: An anchoring device suitable for restraining line arrays comprises a cylir having a plurality of spring loaded flukes spaced both axially and radially from each other. The flukes retract flush into slots in the cylinder so that the anchoring device may be ejected from a submarine through a stuffing tube gland. The flukes until ejected are held in the retracted position by means of a caked water soluble material. A plurality of anchors may be ganged together by means of a coupling assembly. The same coupling assembly is suitable for connecting the anchoring device to the line arrays.

Abstract: A sheeting panel for trenches formed of a rectangular frame and a pair cover plates which collectively define a chamber housing foam plastic reinforced by steel cord mesh or steel cord waste thereby providing the sheeting panel with inherent strength to resist loads placed thereon by earth when the sheeting panel is used for shoring trenches or the like.

Abstract: This invention discloses a novel collapsible tent which is designed to reduce the humidity therein and which utilizes novel ground-holding means to hold it securely to the ground when erected. The tent covering comprises separate inflatable sections which is suspended over a triangular tent-type configuration of tubular support pieces. The tent is secured to the ground by utilizing expandible plugs which comprise a tapering casing with an expandible ring on its lower section. The casing is inserted into the ground and a screw-type device is inserted therein. This causes the casing to expand and to apply radial pressure to the ground thus providing a secure connection to the ground. The tent also utilizes novel eave troughs which are designed to be able to be used as a carrying case for the tubular support pieces once disassembled.

Abstract: A portable, light-weight, earth engageable gun rack adapted, when in use, to safely, effectively and dependably support a brace of two rifles or shot guns in ready to engage and use position and which, when not in use, can be collapsed and folded into a small, neat, convenient to carry package-like unit. When in use, the rack has major dimensions of approximately 40 inches .times. 7 inches .times. 7 inches and when collapsed and folded has dimensions of approximately 18 inches .times. 7 inches .times. 2 inches.

Abstract: An earth auger is disclosed in which an auger shaft is provided with freely expansible and contractible rotary blades in such manner that said rotary blades may expand automatically when said auger shaft is rotated in the forward direction and may contract automatically when said auger shaft is rotated in the reverse direction. Also a method for driving piles and the like is disclosed which comprises the steps of positioning a pile or shoring adjacent to said auger shaft and above said blades, advancing said pile or the like into an earth bore excavated by said rotary blades, and filling said bore excavated by the rotary blades with mortar or the like.

Abstract: Disclosed is an anchoring apparatus for use in anchoring structures to the ground by use of elongated flexible straps. The anchoring apparatus has a lower ground engaging portion which is embedded in the ground below ground level, and an internally-threaded fastener is provided on the ground-engaging portion. A threaded shaft is releasably attached to the fastener of the ground-engaging portion. An upper portion is attached to the threaded shaft for attaching the straps to the shaft. The upper portion is provided with two anchorheads. Each head has first and second flanges extending at an angle with respect to each other. One of the flanges is provided with a bore through which the shaft extends. The other of the flanges is provided with an elongated slot with a flat-sided bar attached to extend across the slot.

Abstract: Disclosed is an anchoring apparatus for use in anchoring structures to the ground by use of elongated flexible straps. The anchoring apparatus has a lower ground engaging portion for attaching the apparatus to the ground; a threaded shaft extending from the lower portion; and an upper portion attached to the threaded shaft for attaching the straps to the apparatus. In one embodiment, the upper portion is provided with one or more heads, each of which has first and second flanges which extend at an angle with respect to each other. One of these flanges is provided with a bore through which the head is attached to the shaft by means of a threaded fastener. The other of these flanges is provided with means for attaching a strap thereto. In this embodiment, the attachment means comprise an elongated slot in the other flange with a flat-sided bar attached to extend across the slot. In another embodiment, a round knurled pin is used in place of the flat-sided bar.
