Reversible, accessories adaptable archery bow sight

Archery bow peep sight for an archery bow string having barrel with an internal hollow passage therethrough. The inner passage has internal front threads, internal rear threads and an intermediate section locking channel. A lens seat with outer annular retainer, a top lens support ring and a frustoconical inner wall is lowered into and locked into the intermediate section locking channel of the barrel. A front peep shade cap with outer threads and a knurled finger grip is threadable into the internal front barrel threads and has a frustoconical inner wall. A rear aperture has outer threads threadable into the internal rear threads of the barrel and a knurled finger grip. The aperture has a frustoconical inner wall and a lower lens cavity whereat a lens is seated. Lowermost flexible lens retainers, that are generally L-shaped, hold the lens within the lens cavity.

A portable, compact, collapsible, adjustable, archery crossbow press for high poundage crossbows which have a rifle-like frame with an elongate channel and transverse limbs with outwardly located cams or wheels connected by a bow string. The crossbow press includes two limb clamp assemblies that releasably capture the transverse limbs about the cams. A flexible connector connects the two limb clamp assembles just above the rifle-like frame. A safety hook block fits within the elongate channel rearwardly of the crossbow string and is anchored to the rifle-like frame. A mechanical cocking device pulls the flexible connector rearwardly to secure it to a hook on the anchored safety hook block.

A hydraulic piston for a cylinder block of a hydrostatic power unit has an elongated cylindrical body with first and second ends. An elongated cavity is formed in the body. A cap is adhered to the body to close the cavity. The cap has an external shape to facilitate the operative engagement thereof with a slipper, which is in subsequent engagement with a swashplate mounted adjacent the cylinder block. The piston has an elongated first conduit formed in the body which is separate from the cavity and extends between the opposite ends thereof. The conduit terminates in registering communication with a second conduit in the cap thereof to permit transmission of oil through the conduit without invading the volume of the cavity. The cap preferably has a tapered surface on the inner end thereof engaging a compatible shaped surface on an adjacent end of the body to center and align the cap with the body. The tapered surfaces of the cap and body terminate in parallel wall surfaces to create a continuous arcuate interface therebetween which is filled with an adhesive material such as a brazing medium. The body member and the cap are of metallic construction with the material of the cap member being more malleable than the material of the body so as to permit subsequent crimping of the cap as may be required. The body and the cap are preferably formed by a metal injecting molding process utilizing a molding material comprised at the time of molding of a mixture of metallic grains and a binder. The body member and the cap are subjected to a debinding process whereupon the binder material is removed from the molding material and the components are sintered whereupon controlled shrinking occurs. The cap is adapted to terminate either in a spherical ball for attachment to a slipper element, or is comprised of a spherical socket adapted to receive a ball element attached to a slipper element.
