Abstract: This isometric/isotonic exercise and physical therapy system is based on a series of elongated exercise rods made of urethane or other resilient, elastomeric resin that is both bendable and twistable. The exercise or therapy afforded by the system depends on the resilient exercise rod or rods; for a relatively limp, low-resistance rod the exercise is essentially isotonic, but with stiffer rods isometric exercise or therapy is provided. The system includes devices that mount the rod or rods on the person using the system for varied exercises of the knee, elbow, hip, wrist, back, or virtually any other portion of the user's anatomy.

Abstract: An exercise and physical therapy device for a human anatomical part (e.g. a foot and ankle) includes a support. An adjustable, resilient torsion device, capable of both twisting and bending motion, has one end affixed to the support; an engagement member, for engagement with a human anatomical part, is mounted on the other end of the torsion device. In one embodiment the support is pivotally mounted on a base plate, and an elevating latch mechanism latches the support at one of several angular positions relative to the base plate. In another embodiment the support constitutes the base of the device and a plurality of bumpers mounted on the support limit angular deflection of the engagement member relative to the support.

Abstract: An adjustable elastomer bias device includes a base member (metal or rigid plastic) having plural receptacles for receiving one end of each of a like plurality of bendable, resilient, elastomer rods. An index member is included in the device; the index member has plural rod guide passages and each elastomer rod passes through one guide passage so that the index member can slide longitudinally along the rods, toward and away from the base member. The index member is anchored at one of several displacement distances from the base member to change the effective stiffness (bias) of the rods. The index member may be rotated for torsional bias or moved laterally for linear bias to effect a further bias adjustment; a retainer holds the additional bias adjustment. The bias force of the device results from bending of the elastomer rods.

Abstract: This isometric/isotonic exercise and physical therapy device employs an elongated exercise rod preferably made of urethane or other resilient, elastomer resin. The exercise rod is releasably mounted, as by a set screw, in a socket that in turn is mounted on a metal base. The exercise rod may have one end secured in the socket; in other embodiments the socket is tubular and the elastomer rod extends through the tube. Different forms of mounting apparatus mount the base of the device on a stable support such as a floor, a desk, a table, a cabinet, a wall, a door, or a door frame. The base mounts include a vacuum cup for surface mounting, a clamp for a table or desk edge mount, and a floor-to-lintel doorway mount. The exercise/therapy use of the device depends on the resilient elastomer exercise rod; for a limp, low-resistance rod the exercise is essentially isotonic, but with stiffer rods isometric exercise is provided.

Abstract: An adjustable elastomer torsion device includes a base member aligned in partially nested relation with a resilient elastomer (e.g. rubber or urethane resin) torsion member; parts of the base member and the torsion member overlap each other and an extension portion of the torsion member projects beyond the base member. The base member and the torsion member are interlocked, where they overlap each other, to prevent relative twisting between them, but the interlock does not interfere with twisting of the torsion member extension. An adjustment mechanism provides for adjustment of the positions of the base and torsion members relative to each other to vary the length of the extension portion of the torsion member over a given displacement length and thereby adjust the elastomeric, resilient torsional restoration force (torsional resistance) of the device within a predetermined force range.

Abstract: A primary conveyor belt cleaner includes an elongated support extending across but spaced from a conveyor belt of width W and includes a stiff guide extending for approximately the full length of the support; a scraper blade of resilient elastomer resin is mounted on the support and engages the conveyor belt surface. The scraper blade has a short base wall removably mounted on the support by a reinforcement that interfits with the guide; the blade has two longer curved side walls, an inner wall concave toward the belt and an outer wall convex away from the belt. The two side walls come together to form a scraping edge. The belt cleaner includes a torsion bias mechanism that resiliently maintains the belt scraping edge in continuous engagement with the belt. Two or more primary cleaners may be incorporated in one system. Flexure of the blade permits passage of a mechanical splice in the belt without appreciable damage to the blade or the splice.

Abstract: A secondary conveyor belt cleaner includes a metal support of length L1 and a metal guide of continuous or intermittent construction; the support extends across a conveyor belt of width W in spaced relation to the belt. A plurality of belt cleaner blades of total length L2 (W.apprxeq.L1.apprxeq.L2) are mounted on the guide by a plurality of metal cantilever support arms, usually forged aluminum, one per blade; on each arm there is a metal reinforcement that fits snugly in a base wall in its blade. Torsion bias acting on the support rotationally urges the blades against the conveyor belt.

Abstract: A resilient rotational bias device that is continuously adjustable to supply any preselected rotational bias force to a shaft, within a wide range, by rotation of a multi-step shaft retention member, usually a gear, by a simple drive such as a worm gear that engages the shaft retention member; the shaft retention member an the drive are mounted in a housing that is affixed to one end of a resilient torsion member, the other end of the torsion member being affixed to a stationary frame. All elements of the device other than the torsion member, but including a connector for connecting the shaft retention member to the end of a biased shaft, are mounted in the housing. All elements of the device, except a drive shaft for th worm gear, are usually formed of the same molding resin, preferably polyurethane.

Abstract: A skirtboard apron for a belt conveyor is formed as an elongated molded or extruded elastomer member having a U-shaped upper mounting portion that slides onto the lower part of a skirtboard; the legs of the U-shaped mounting portion grip the sides of the skirtboard. A wiper portion of the apron, integral with the mounting portion, projects down into engagement with the conveyor belt. No fasteners are required, and no wear adjustments are necessary.

Abstract: A skirtboard member is adjustable and replaceably mounted on a wall above a belt conveyor by a mounting assembly including a cam member molded from a tough, durable resilient resin (e.g., urethane); a key aperture and two radial keyways in the cam member are aligned with two cam ramps that each end in a key latching depression. A key including a shaft and two radial key elements is inserted through the cam member aperture and keyways and twisted to drive the key elements along the ramps to latched position, where a head on the key clamps the skirtboard member on the wall.

Abstract: A rod hole plugging system for providing an effective permanent plug within a tie rod hole extending through the thickness of a poured cement wall utilizes a short, low cost plug selected from natural fibre or synthetic foam, which is soaked by a liquid resin coating which is seasonally selectible to meet environmental conditions. The selected plug has a diameter exceeding that of the rod hole to be plugged. The selected group of resins is water-tolerating and impermeable, and may be a high solids polyisocyanate prepolymer that will harden to a polyurethane polymer; or it may be a selected mixture of epoxy resin and hardener. The plug is soaked in the resin, and is then diametrically compressed and inserted within the interior (i.e., inside the foundation of the structure) end of the rod hole being treated. The elastic memory of the plug material causes it to swell and engage the walls of the rod hole, in which condition the liquid resin sets up.

Abstract: A plurality of molded, resilient elastomer blade supports are mounted on and keyed to a shaft extending across and spaced from a conveyor belt; each blade support includes an integral blade mount projection on which a scraper blade is mounted. A torsion bias mechanism, using a resilient resin torsion tube, biases the shaft to rotate the scraper blades toward the conveyor belt to compensate for wear and absorb shocks. In some embodiments, the blades are integral with the blade supports; in others, each blade is connected to its support by a connecting rod that includes a resilient joint for added flexure in the overall scraper structure.

Abstract: An improved scraper blade for use in cleaning particulate conveyed material from a belt conveyor, the blade being mounted on a shaft which extends across the conveyor belt in spaced relation thereto. The scraper blade includes an elongated block of molded elastomer material, mounted on the shaft, which has a leading edge and a trailing edge extending across and in contact with the conveyor belt. The scraper blade surface intermediate its leading and trailing edges has a shallow concavity or pocket, spaced from the belt, in which a limited quantity of particulate conveyed material collects. The collected material itself scrapes the conveyor belt to assist in dislodging particulate matter from the belt.

Abstract: An adjustable, quick-release clamp for fastening a barrier member to a base member includes a clamp support affixed to the base member and protruding therefrom, a main lever carried by the support member, with the support member extending through an aperture in the main lever, and a retainer member that holds the main lever on the support member. A first end of the main lever carries a gripper means adapted to engage the barrier member; an overcenter toggle cam is pivotally mounted on a second end of the main lever, a handle lever being attached to the cam. The cam is movable to raise and lower the first end of the main lever, with the retainer member acting as a fulcrum such that the gripper means engages or releases the barrier member in accordance with the positioning of the toggle cam. The position of the retainer member on the clamp support is adjustable to permit accommodation of variable barrier member thicknesses and to provide for adjustment of the clamping pressure.
