Abstract: A suction cleaning apparatus as described below is a suitably shaped reservoir for enclosing any suitable cleaning fluid such as water or saline solution. Within the reservoir of cleaning fluid are one or more cleaning cylinders. The cleaning cylinders may adopt any suitable length to enclose a single cleaning bristle in the bore of the cleaning cylinder. The upper portion of each cleaning cylinder may have a generally conical or funnel shape, forming guide section to direct the distal end of a suction tube into alignment with the cleaning bristle coaxially aligned with the long axis of the bore of the cleaning cylinder. In use, an obstructed suction tool is inserted into the cleaning fluid and pushed into the cleaning cylinder thereby engaging the bristle. The bristle is sized such that the bristle extends into the obstructed suction tool to mechanically disengage the obstruction.

Abstract: A suction cleaning apparatus is a generally cylindrical vessel for enclosing any suitable cleaning fluid such as water or saline solution. A generally planar cleaning plate with an upper and lower surface is supported a suitable distance from the cup floor by a plurality of legs forming a fluid plenum between the lower surface of the cleaning plate and the cup floor. The upper surface of the cleaning plated has a plurality of bristles extending from the upper surface for mechanically cleaning an obstructed suction tool. In use, an obstructed suction tool is inserted into the cleaning fluid and pushed into engaging the bristles. The bristles are sized such that one bristle extends into the obstructed suction tool to mechanically disengage the obstruction. The bristles may include a central channel for conducting cleaning fluid from the fluid plenum to the tip of the bristle increasing fluid flow into and obstructed suction tool to expedite clearing the obstruction.

Abstract: An archery bow sight has a sight tube which is fixed to a link arm which extends between two rotatable members mounted to a frame which is connected to the riser of a bow. The arm is pinned to the rear rotatable member at a radius which is less than the radius at which it is pinned to the front rotatable member. The rotation of the rotatable members is synchronized by a connector such as an intermediate gear, a timing belt, a rigid link, or a linked chain. By rotation of a range adjustment knob, the sight tube is caused to change simultaneously in inclination and in height in such a way that the archer may continue to view the target through the sight tube. The sight tube has a fiber optic sight point. The relationship between the rotating members and the link arm is adjustable for draw length.

Abstract: Two generally triangular segments of metal or plastic are rigidly or pivotably connected at an angle of about 45 degrees. A flexible strap extends through vertical slots formed in each segment. A strap connector, such as a double bar buckle, is positioned between the two segments. The strap extends through the first slot and around a portion of the strap connector, back out the first slot and around the joint between the segments and into the second slot. The strap passes from the second slot, around a portion of the strap connector, back out the second slot and then around the tree. The free ends of the strap are releasably connected. The edges of the segments may have upwardly angled teeth, such that when the tree step is secured against the tree by downward pressure, the upwardly angled teeth restrain the upward return of the tree step in response to the tension in the strap. Installed, strap tension restricts opening of the two segments, while the strap connector restricts collapse of the two segments.

Abstract: Adjustable upper straps extend from the four corners of a collapsible seat assembly and terminate at a central O-ring. A groin strap extends from the central ring to a portion of the seat assembly. A tree ascender strap is also connected to the central ring, and has a latchable hook which can be used to encircle the trunk of a tree and secure the climber as he climbs. A back strap and shoulder strap extend from the central ring and help to restrain a hunter within the assembly both while climbing and while in an elevated position in the tree. A main lead securing strap extends from an extension strap connected to the central ring and has a buckle which allows it to be secured around a tree above the head of the hunter. The main lead securing strap is looped through itself in such a way that the strap chokes the tree trunk within itself to prevent slipping on trees with smooth bark.

Abstract: A protective case for fishing hooks and lures wherein the protective case is mounted to a fishing rod.

An opening formed in the end of both outer housing member 12 and inner housing member 32 provides for continuous engagement with a fishing line. An aperture cap provides a bottom for the enclosure, which may be removed to clean debris that has accumulated therein. The protective case may be attached to a fishing rod through any of a variety of methods including a V-shaped clamping member, hook and pile straps or a spring clamp.

Abstract: An adjustable compound leverage bowstring release which may be held in the hand of an archer includes a housing assembly, a latch cam which is pivotally mounted to the housing assembly and a trigger cam which is also pivotally mounted to the assembly. The housing assembly has an outer contour which is shaped to be grasped by the hand and also has a slot for receiving a bowstring. The latch cam has a notch which receives the bowstring when the bowstring is pulled into the housing assembly slot. As the bowstring is pulled back into the slot, the latch cam is pivoted from its open position to a latched position. In its latched position a lever portion of the latch cam moves through a lever pathway. The trigger cam then is pivoted so that a smooth wall on the trigger cam intersects the latch cam lever portion pathway to prevent the latch cam from returning to its open position.

Abstract: A portable tree seat has a generally flat platform with a back edge for engaging a post or tree and is held in position on the tree by a rope. A flexible strap is secured to the platform near its front edge and extends to the back edge of the platform where it is adjustably secured in position by being passed through a pair of slots formed in the platform. A rigid elongated brace is attached to the flexible strap and is cradled therein between the positions of securement of the strap to the platform. When the back edge of the platform is held in position on a tree, the flexible strap may be adjusted such that the brace is held by the strap in a position engaging the tree at its back end and extending up to a position supporting the platform at its front end so that the platform is held in a substantially horizontal position. The brace is held only by the strap so that the brace may shift to its most stable position when the platform is loaded.
