Abstract: An aerodynamic multi-bladed expandable broadhead with rearward mounted overlapping blades with greater in-flight blade angles along with substantially perpendicular blade edges relative to the arrowhead body. Position of blades in flight guarantees they will always make a lethal cut on contact with an animal even before expansion. Greater in-flight blade angle means less force to open blades on hide guaranteeing expansion, and minimal rotation of blades to the penetration position results in a maximum entry cut and greater penetration. By expanding the distance between the blade edge and pivot a stronger blocky blade is produced. Geometry dictates during entry when blades hit bone on angle shots arrow direction will favorably remain in its intended lethal path to an animal.

Abstract: A noise reducing bowstring suppression device consisting of an individual length of pliable material supported between dual support members mounted on a bow, a bowstring on the bow contacting the pliable material when the bow is shot.

Abstract: A broadhead includes a one-piece elongated ferrule, with a plurality of slots through a central longitudinal axis of the ferrule, at least one of which has an open end, and one-piece blades mounted in the slots. At least one of the blades includes a blade slot in it and the blades having openings through them. A securing member is inserted transversely through the central longitudinal axis of the ferrule and passes through the openings of the blades securing them within the ferrule.

Abstract: Lever Regulated Compound Bow uses multiple groove modules on the limb tips to spool bowstring and cables to provide desired energy storage and nock travel, while simultaneously using a lever to regulate cam synchronization, using split cable harnesses to deter limb twist, and lever blocking draw stop means.

Abstract: A broadhead includes a one piece elongated ferrule, with a plurality of slots through a central longitudinal axis of said ferrule, at least one of which has an open end, and one piece blades mounted in the slots. At least one of the blades includes a blade slot in it and the blades having openings through them. A securing member is inserted transversely through the central longitudinal axis of the ferrule and passes through said openings through the openings of the blades securing them within the ferrule.

Abstract: An archery bow (B) having at least one draw force module (1a or 1b). The module includes a concentric bowstring (3) pathway (12a) and at least one eccentric cable (6a) pathway (7a) with a decreasing radius proportional to the increasing spring rate of the flexing limb so the peak weight remains the same through a portion of the draw force curve and decreases at the end.

Abstract: An arrowhead with a removable blade captured within a doubly terminated slot is disclosed. When a number of blades are used, the interlocking blade bodies have complementary recesses whereby each interlocking blade is received into the other interlocking blades. The arrowhead may be integral with and a portion of an arrow, or it may be a separate, detachable ferrule. The tip of the arrowhead is either a unique slotted pyramid, or a conventional cone or spear. Securement of a blade within the arrowhead is achieved through an attachment to the arrowhead. This attachment may perform other functions in the arrowhead, for instance the attachment may also function as the tip of the arrowhead.

Abstract: An adjustable sight for an archery bow has a hollow barrel open at at least one end, the barrel having an interior side wall, and a sliding member mounted in the barrel. The barrel is mounted parallel to the long dimension of a bow, and the sliding member projects beyond an open lower end of the barrel. The sliding member has annular channels in it, in which O-rings are mounted that engage an inside surface of the barrel with sufficient force to inhibit unwanted sliding of the plunger but to permit the plunger to be moved manually by the user of the bow, even when the bow is at full draw. The sliding member carries an aiming device, such as an adjustable sighting pin.

Abstract: In an exercise apparatus for exercising having a horizontal bar and a plurality of weights, the weights including a bar receiving slot opening through the lower edge of the weight, and a closed end intermediate the height of the weight and above the center of gravity of the weight when the bar is at the closed end of the slot, the weight being gravity biased to a position where the open end of the slot is below the bar.

Abstract: An apparatus for mixing or blending chemicals includes a dedicated pump for each type of chemical to be blended, such as one pump for water-based chemicals and another pump for oil-based chemicals. Each pump preferably operates in a fast speed when delivering the majority of a particular chemical into a vending vat. When the desired amount of a chemical has almost been pumped into the vat, the pump switches to a slower speed to add the remaining amount. Then, the pump is reversed to clear the chemical from the line so that another similarly based chemical can be pumped through the line into the vat.

Abstract: A hunting arrowhead carried by an arrow shaft includes at least one blade cluster made up of at least two blades in side-by-side relation, substantially parallel to one another and with cutting edges spaced from one another to make closely spaced, parallel cuts as they penetrate.

Abstract: A diaphragm type game call has at least one diaphragm mounted in a frame in such a way that the diaphragm cooperate with a part or parts of the frame to permit the tension of the diaphragm to be varied selectively, as by fixing the initial effective length of the diaphragm at the outboard edge of a leg of a U-shaped frame whereby the inboard edge serves as a fret of sorts to shorten the effective length of the diaphragm when the diaphragm is pushed against it by the tongue of the user, or by providing a fret intermediate the length of the diaphragm, or by providing one or both legs of a frame with channels into which and from which a diaphragm can be readily mounted and demounted to permit the selective tensioning of the diaphragm so mounted.

Abstract: A game call of the type known as a mouth call, has a plurality of generally elongatedly rectangular, planar, thin, flexible diaphragms secured at opposite short edges in a frame, the diaphragms lying adjacent one another in substantially the same plane, each of the diaphragms having a trailing and a leading long edge, the trailing edge of the diaphragms being substantially parallel to and spaced from the leading edge of the next successive diaphragm.
