Abstract: The adjustable batter board may comprise a first clamp, a second clamp, a hook, and a position adjuster. The adjustable batter board may removably couple to a horizontal crosspiece of a batter board via the first clamp and the second clamp. A string line may be removably coupled to the hook. As a non-limiting example, the string line may designate a layout line of a construction project. The position adjuster may be operable to move the hook laterally in order to position the string line. A plurality of jam nuts may be operable to lock the hook into position.

The arm portions initially extend from the coil in substantially parallel planes, each arm portion initially extends away from a longitudinal axis of the releasable clip, and each arm portion extends from the coil to a respective shoulder portion. A first leg portion and a second leg portion, each leg portion extends from a respective shoulder portion, and each leg portion initially extends toward and crosses the longitudinal axis of the releasable clip. A first arch portion and a second arch portion, wherein each arch portion extends from a respective leg portion to a respective terminal end.

Abstract: A fishing lure line connector is provided with an undivided, single width, unitary elongated member shaped to form first and second eyelets at its respective ends and a circinate hoop, the first and second eyelets axially aligned and residing outboard of the circinate hoop. A method of attaching a fishing lure line connector to a fishing lure having a connection feature is also provided, comprising providing a fishing lure line connector having a hoop and first and second axially aligned line apertures connected to and disposed outboard of the hoop, and moving the connection feature between the first and second line apertures to within the hoop.

Abstract: A clamp for holding shut and submerged a coffee filter containing coffee grounds or the like inside a vessel comprises one strand of wire formed such that an arc-shaped portion separates two arms. A first arm possesses a first jaw of the clamp. A second arm possesses a bent loop portion that functions as a second jaw of the clamp. The first jaw protrudes slightly through the second jaw when the clamp is in its free state. Pushing the first jaw farther through the second jaw expands a “window” in which an object can be placed, while bending the arc portion. After removing pressure from the arms, the clamp will release some of its stored mechanical energy, gripping and holding an object within the clamp's window portion by way of the remaining stored energy within the clamp and from the friction between the object and the clamp's window portion.

Abstract: A device to adjust the effective length of a sling during the transport of a load is designed as a continuous loop with a carrier part. The carrier part has projections located at each of two opposed spaced sites. Each of said projections supports a segment of the sling. The carrier part also has an opening through which a loop segment of the sling is guided.

Abstract: The present invention is a safety hook (12, 12?) having a wire spring latch (26, 26?). The wire spring latch (26, 26?) is a wire loop pawl. The safety hook (12, 12?) is made of a heavy gauge wire form material, which is preferably bent only to form first and second ends (14, 14?, 16, 16?), a chain link securing end (14, 14?) and a hook opening end (16, 16?), respectively. The wire loop pawl (26, 26?) is preferably a rod of elastically deformable material, bent to form an open loop (28, 28?) and bent-over ends (32, 32?, 34, 34?) about which the pawl (26, 26?) pivots with respect to the body (12, 12?) of the safety hook (10, 10?) when the latch (26, 26?) is deformed and forced away from a distal end (38, 38?) of the hook opening end (16, 16?) of the safety hook (10, 10?). The bent over ends (32, 32?, 34, 34?) of the wire loop pawl (26, 26?) are not coaxial.

Abstract: The present invention is a safety hook (12, 12′) having a wire spring latch (26, 26′). The wire spring latch (26, 26′) is a wire loop pawl. The safety hook (12, 12′) is made of a heavy gauge wire form material, which is preferably bent only to form first and second ends (14, 14′, 16, 16′), a chain link securing end (14, 14′) and a hook opening end (16, 16′), respectively. The wire loop pawl (26, 26′) is preferably a rod of elastically deformable material, bent to form an open loop (28, 28′) and bent-over ends (32, 32′, 34, 34′) about which the pawl (26, 26′) pivots with respect to the body (12, 12″) of the safety hook (10, 10′) when the latch (26, 26′) is deformed and forced away from a distal end (38, 38′) of the hook opening end (16, 16′) of the safety hook (10,10′). The bent over ends (32, 32′, 34, 34′) of the wire loop pawl (26, 26′) are not coaxial.

Abstract: Resistivity mapping apparatus includes a tow mechanism for use by a human operator in moving the mapping apparatus over a surface and measuring the resistivity of soils of the surface. The tow mechanism includes a generally triangular shaped tow ring which is engageable by the operator's battery belt, harness, or pack-frame, the tow ring having two opposing hooks at a vertex of the tow ring for receiving a loop from a tow line. The tow line engages the tow ring and a cable depressor weight which keeps the resistivity mapping apparatus in close proximity to the earth as the apparatus is towed. A communication cable in the tow line preferably comprises an optical fiber which transmits signals from the receiver to a data logger carried by the operator.

Abstract: A reversibly attachable fastener has a generally figure-8 geometry when in the engaged state. The fastener is composed of two generally symmetric halves, each comprising arm portions, shoulder portions, and head portions, and the halves are connected by a spring loop. One half of the fastener contains a window feature that allows the opposing, singular half to extend through and be supported in a nested fashion. The half containing the window feature has crown protrusions on the head portions which are then spanned by a bridge structure. The opposing, singular half is provided with a crown protrusion which is notched, this crown protrusion catching on the bridge structure to maintain the fastener in the engaged state. The fastener can be used to easily and reversibly attach various objects, such as keys to keyrings or identification tags to luggage.
