Abstract: A fishing lure comprising at least one fish hook having two retainers on its shank, a piece of flexible material wrapped around the shank between the retainers, the material having first protrusions on one side and second protrusions on the other side, the first and second protrusions being adapted to releasably interlock with each other, a skirt or other visible lure assembly attached to the strip and secured to the shank thereby.

Abstract: Apparatus is provided for removing coils of scrap wire or cable (103) from about a reel (100) comprised of an array of juxtaposed cutting blades (50-53) and apparatus (60-63, 54-57) for reciprocally driving each of the blades independently along a different path in a group of mutually juxtaposed paths. Apparatus (16) is also provided for supporting the reel with the reel flanges straddling a portion of the group of paths.

Abstract: A continuous cold cut slicing system utilizing a slicing machine having a conveyor which feeds a loaf into engagement with a series of drums located on each side of the slicing machine channel; the drums are driven by a variable speed motor with the rotation of the drums providing a feed mechanism of the product to the slicing blade. A gripper assembly is provided which rides on a guide shaft adjacent the channel with the movement of the gripper in the channel constantly being monitored by an encoder and clutch arrangement connected thereto. As the gripper approaches the knife, the encoder and clutch arrangement provide for a drag on the gripper thereby controlling the feed of the product compensating for pull on the knife. Also, since the encoder and clutch arrangement are constantly monitoring the position of the gripper the exact location of the tail end of the loaf being sliced is readily determinable so that a profile compensation control system may be effectively incorporated into the system.

Abstract: A lapping machine includes a circular drive plate mounted on the end of a driven shaft and a circular lapping plate mounted on the drive plate. A pair of leveling levers are mounted between the drive plate and the lapping plate with each lever being in a groove in the drive plate. Each lever has a pivot point adjacent one end which is pivotedly seated on the drive plate and projects from the groove in the drive plate so that the lapping plate engages the lever. An adjustment screw is at the other end of each lever for adjustably pivoting the lever and thereby tilts the lapping plate with respect to the drive plate. Either the lapping plate or the drive plate has holes therethrough to permit access to the adjustment screws. A drive pin projects from the drive plate and fits in a groove in the bottom of the lapping plate to drive the lapping plate with the drive plate.

Abstract: A portable knife sharpener comprising two duplicate bar or narrow plate-like clamp members connected together adjacent to but spaced from their one ends for pivotal movement about axes generally parallel with the planes thereof and having facing planar surfaces with linear edges at their ends closest to their pivotal connection. A thumb screw is threaded in one of the clamp members intermediate its end opposite to said one end and its pivotal connection with the other clamp member the end of which clamp screw abutts the other clamp member. A discrete flange or angle-like member is pivotally connected by one flange part thereof to the side of each of the clamp members not facing the other clamp member with the other flange part of the member extending normal to the planar surface of the clamp member to which it is connected. Each of said angle-like members has a plurality of apertures therein spaced like distances from the planar surface of the clamp member to which it is connected.

The damping piston defines a control cylinder and the base of the damping cylinder carries a control piston adjustably fixed in the control cylinder in axial alignment with the damping piston over the entire stroke distance. A pneumatic fluid supply line in the control piston connects the damping cylinder with the control cylinder and is provided with a non-return valve.

Abstract: An artificial lure (10) is provided which simulates the natural motion of a living creature as the lure is drawn through water. The lure (10) comprises a resilient body (12) having a head portion (26), a mid-body portion (28) and a tail portion (30). The mid-body portion narrows in a first direction to form a hinge section (38) and protrusions (40, 42) extend outwardly from opposite sides of the mid-body portion (28) adjacent the hinge section (38). Recesses (44, 46) are formed by the protrusions. As the lure is drawn through water, the flow along the lure induces oscillation in the tail portion (30) which resembles the motion of the living creature.

Abstract: A system for cutting generally planar quadrilateral workpieces into a plurality of quadrilateral elements, at least a portion of which have both their length and width dimensions smaller than the overall length and width dimensions of the original workpiece wherein cuts extending completely across the workpiece parallel to one of the length and the width dimensions thereof are first effected by a first saw with the cut pieces being then conveyed to a third saw where cuts completely thereacross may be made in directions perpendicular to the one dimension. The remainder of the workpiece is conveyed to a second saw where cuts are made in directions parallel to the other of the length and width dimensions with the cut portions of the workpiece remainder being subsequently conveyed to the third saw for effecting cuts in the cut portions in directions parallel to the one dimension.

Abstract: A blade tensioning mechanism for a band saw is provided with a block slidably mounted on the saw frame and carrying a movable, non-driven, i.e., idler, band saw blade wheel. A link extends through a cam follower secured to the block and carries a pivotally mounted cam for engaging the cam follower. The end of the link opposite the cam is threaded and is engaged in a threaded bore of a rotatable shaft which is carried on the frame and which is restrained against displacement relative to the frame. A handle is connected to the shaft through a preset torque limiting device whereby the blade can be pretensioned to a predetermined amount by turning the handle to move the link, cam follower, block, and idler wheel relative to the frame. The cam can be subsequently pivoted against the cam follower to further move the idler wheel a predetermined amount to apply a final, operational tension.

Abstract: A continuous cold cut slicing system utilizing a slicing machine having a conveyor which feeds a loaf into engagement with a series of drums located on each side of the slicing machine channel; said drums are driven by a variable speed motor with the rotation of the drums providing a feed mechanism of the product to the slicing blade. A gripper assembly is provided which rides on guide shafts adjacent said channel with the movement of the gripper in the channel constantly being monitored by an encoder connected thereto and positive drive is supplied to the gripper towards the blade by a clutch means in conjunction with a rack and pinion arrangement. The positive drive may be synchronized with the feed of the drums. As the gripper approaches the knife, the drag may be placed on the gripper thereby compensating for pull of the blade.

Abstract: A device for catching crabs is described comprised of a frame portion and attached net structure. The frame portion, comprised of three U-shaped members, can be deployed to a functional state having a perimeter from which said net structure is suspended, and a handle adapted to receive a tether line used to lift the device vertically from a body of water. When placed in a collapsed state for storage, the three frame members lie closely adjacent each other, thereby occupying considerably less space than the device in its deployed state.

Abstract: A floating container, specially adapted to hold live bait, which is shaped like a small boat so that it can be pulled behind a fishing vessel without sinking. The container is transparent so that the bait carried therein can be seen and thus attract game fish in the surrounding water. The container is structured to provide proper aeration for the bait, yet allow access to it when needed. Closure doors are positioned to shut independently when the container is being towed.
