Abstract: A portable, positive pressure fan for fire fighting provides a three-leg frame with a platform supporting the fan and its driving engine. The platform carries two forward, laterally spaced collars and one rearward collar to adjustably receive the three legs for support spacedly above a supporting surface. The legs are adjustably positionable in the collars to allow vertical adjustment to regulate fan height and angulation relative to a supporting surface, have an arcuate configuration and are somewhat resilient to absorb and damp operative forces, and the leg array alleviates or negates walking of the structure on a supporting surface caused by vibrations resulting from operational forces. The fan has a blade with diametrically opposed lobes of the aircraft propeller type to create a narrow cone of pressurized air and preserve as great a volume and velocity of such air as possible at ordinary operating distances.

Abstract: A tool to releasably engage in a channel of a concrete block for lifting provides an elongate body rod defining a fastening loop in its upper portion and carrying in its lower portion two radially extending fins having an obtuse central angle less than a straight angle therebetween. Each fin pivotally supports vertically spaced, parallel connector links that pivotally interconnect vertically orientated fastening arms for similar radial motion. The body provides at least one fixed fastening arm extending on a line bisecting the central angle between the two fins. Release mechanism provides a release collar slidable on the body between the fins and fastening ring. The collar pivotally carries connector links that interconnect with the upper fastening arms to radially move the fastening arm responsive to collar motion. A compression spring carried about the body rod between the collar and the fastening ring biases the collar downwardly and responsively the fastening arms outwardly.

Abstract: A locking wheel chock, for positioning between adjacent tandem wheels on spaced axles of a vehicle having no independent braking system provides upper and lower pairs of wheel contacting blocks connected in spaced relationship by a telescoping body assembly. The telescoping body assembly carries a rack on one portion and a fastening lever with a partial pinion on the other portion to engage the rack to adjust the length of the body assembly to move the wheel blocks into and out of fastening engagement with the tandem wheels for preventing relative rotation. Each wheel block is independently pivoted to allow tangential contact with the adjacent tire tread. A lock prevents movement of the fastening lever to maintain positioning and prevent tampering with the wheel chock when the fastening lever is in fastening position. A first species of wheel block provides paired adjustably spaced blocks on each side of the center line of tandem wheels.

Each medial column below the uppermost element defines an upstanding fastening structure to pivotally mount another column element thereabove. A dome-like cover is releasably supported on the periphery of the base to enclose the medial portion of the base and the medial column structure.

Abstract: A ligature tool, of the type having a handle carrying an elongate body defining a fastening clip chamber in its forward part with ligature tubing holding and tensioning means carried on the body, provides improved crimping and tubing holding means. The crimping element provides a single pivotally mounted crimping dog that contacts a slit portion of an annular ligation tube clip carried in the fastening clip chamber and is movable into that chamber to crimp the sides defining the slit toward the adjacent inner surfaces of the annular clip body to fasten ligation material therebetween. The tubing holding means provide a body supporting similar laterally opposed tubing holders each having a headed vertical post about which the end portion of tubing is wound under tension before placement in an adjacent wedge-shaped slot for releasable fastening. The tubing holding body also provides tubing cutting structure.

Abstract: A mobile orthopedic device to support a disabled leg of a standing patient while the leg is bent at the knee, especially as when partially amputated or encased in a cast or support device. A base having peripheral caster wheels supports a medial upstanding support shaft that is adjustable for height. The upper portion of the support shaft carries a horizontal support with padded upper surface configured to cradle the knee and adjacent lower leg of a patient. A handlebar assembly extends upwardly from the forward end of the horizontal support to aid user support, steerage and maneuvering of the device. A medial, adjustably depending foot optionally aids positional maintenance of the support on a supporting surface. A first species provides a releasable, adjustably positionable strap and knee pad that are carried on the upper surface of the horizontal support to aid positional maintenance of a supported leg to prevent overturning of the support in a forward direction.

Abstract: A nipper tool to remove a peripheral portion of the lip of a bivalve mollusk shell, and especially the shell of an oyster, to aid opening with a shucking knife provides a peripherally defined angulated handle structurally interconnecting a peripherally defined cylindrical nipping body. The nipping body defines an insertion notch in its lower forward portion distal from the handle to provide access to the nipping body chamber which slidably carries a nipper plunger with depending nipper blade to nip the lip of an oyster in the insertion notch. The nipper plunger is biased downwardly in the nipper body chamber by a compression spring and movable against this bias by a bell crank extending into the handle structure. A first manually operated species provides a pivotally movable lever adjacent the handle, with linkage to the bell crank to move the nipper plunger against its bias and release it to nip an oyster shell lip.

Abstract: A two-wheeled trailer carries an adjustably rotatable crane to allow loading and placement of grave headstones by a single worker. The trailer provides a ladder type frame supporting a bed with upstanding sides and openable tailgate. The frame is supported for locomotion by a two-wheeled truck and has tongue structure with vertically adjustable supports. The tongue structure immediately forwardly of the body supports a crane base that journals an angulated crane mast carrying a boom structure, with adjustable braking mechanism communicating between the mast and base to regulate rotation of the mast. The crane mast carries a hoist to move a cable supported by a sheave at the outer end of the crane boom for vertical lifting at the end of the boom. The trailer frame has an adjustable outrigger support to prevent vehicle tipping on inclined support surfaces or when supporting laterally extending masses.

Abstract: An adjustable holder for use in a vehicle to positionally maintain variably sized beverage containers. The holder provides a flat base carrying two upstanding spacedly opposed columns defining a slot therebetween to allow passage of a cup handle therethrough. Each column carries a flexible, circumferentially extending support arm that partially encircle a cylindrical beverage container in opposite directions to overlap and releasably fasten to each other in their outer end parts, in a first species by hook and loop type fabric fastening structure carried on adjacent support arm surfaces and in a second species by a ratchet type fastener. The base of the holder is releasably fastenable on a carpeted surface for positional maintenance by four radially extendible carpet hooks that are biased inwardly by an elastic member interconnecting all hooks. The bottom surface of the base also provides hook and loop type fasteners for optional fastening on solid surfaces such as a dashboard or center console.

Abstract: A wheel to support a pipe, or a tower carrying a pipe, of an agricultural irrigation system, especially of a rotary type, provides a polygonal metal web with feet pivotally mounted by foot supports at the vertices of the web. The feet have relatively wide base elements for support on unstable wet earth that define depending protuberances oriented perpendicularly to the direction of travel of the wheel to minimize rut creation of waterflow along ruts in the earth being traversed. Foot supports carried by the wheel provide two spaced radially extending pivot elements about which the supported foot pivots in sequence in moving over supporting earth to lessen the vertical component of motion of the wheel.

Abstract: A connector is disclosed to releasably attach a horizontal tubular element of a mobile patient support and a vertical tubular element of an intravenous infusion apparatus (I.V.) support apparatus having wheels for locomotion. The connector provides a medial body rigidly carrying an adjustably fastenable I.V. support fastening arm extending therefrom in a first direction and pivotally carrying a patient support structure fastening arm comprises a bracket extending in a second opposite direction. The patient support structure fastening arm defines a fastening channel in its outer part and is biased to a fastening mode by spring means extending between the fastening the arm and the body.
