A double fluke anchor having a pair of flukes lying in a common plane is welded to a crossbar. An elongated stock projecting forwardly of the flukes at right angles to the crossbar and lying in the plane of the flukes is journaled on the crossbar for limited relative rotation. The forward end of the stock is fixed to the forward end of a hairpin shank having its widest dimension at an intermediate point, approximately in the plane of the pivot of the cross bar and converging toward both ends to form a closed loop. A sliding ring connects the anchor line and the hairpin shank and is freely slidable to both ends of the hairpin shank. With this construction, the anchor may be weighed with the flukes lying adjacent the axis of the hairpin shank with the tips of the flukes pointed downwardly.

A three-position safety for a firearm is provided that includes a lever that is rotatable from a first position wherein the bolt and the firing pin are unlocked, to a second position wherein the bolt is unlocked and the firing pin is locked, to a third position wherein the bolt and the firing pin are locked. A detent member has a detent surface to mate with detent apertures on the end of the bolt. When the safety lever is in a first position or a second position, a gap exists between the shaft of the plunger and the detent member allowing for rotational movement of the bolt relative to a cocking piece housing. When the safety lever is in a third position, the shaft of the plunger contacts the detent member such that no rotational movement of the bolt is provided.

A semi-automatic pistol includes a polymeric frame, a barrel secured to the frame medially of its front end and rear end. A slide is slidable relative to the frame without direct engagement therewith. A retainer and guide member is removably secured adjacent a rear portion of the frame and includes a pair of outwardly extending guides. Each of the guides slidably fits within one of a pair of opposing inwardly facing longitudinal grooves. Each of the grooves is disposed along opposed inner surface portions of the slide for retaining and guiding the slide in generally parallel spaced relation to the frame. The pistol includes a second retainer and guide means adjacent the front end and includes, at least in part, a generally circular aperture in a depending front wall of the slide and wherein the muzzle end of the barrel extends through the aperture. The aperture has a predetermined chamfer to enable the slide to disassembled from the pistol after the first retainer has been disconnected from the frame. The chamfer thereby enables the freed, rear end portion of the slide to be pivoted upwardly to a substantial angle generally related to the chamfer whereby the slide may be removed from the barrel and thus disassembled from the pistol.
