Abstract: An improvement setter and method of operation for maintaining and reconfigurating the shape of a malleable pattern used in molding of parts. The setter includes an arrangement for arranging the pattern against the setter using vacuum.

Abstract: A method and apparatus for creating a pattern in the surface of a golf club part having a surface area lacking smoothness using a radiated beam to make portions of such surface smoother. The disclosure is also directed to the golf club part created by the operation of such method and apparatus.

Abstract: A method for treating the surface of a golf club part having a non-smooth surface such as a part which has been cast. Preferably, in those instances where the part is cast, the part is abraded for example by tumbling or by directing a light sandblast against the part to create a low reflectivity surface. Such abrading roughens the golf club part so that greater contrast can be obtained using radiated beam treatment. Surface roughening can also be created by acid etch or other suitable method. The club part is mounted in a beam treatment station to permit projecting a radiated beam on selected areas of the part's surface resulting in the momentary and superficial melting or fusing of the surface which makes such areas less rough and more light reflective than adjacent surface areas. Patterns are formed by causing relative movement between the part and a high energy heat source such as a radiated beam. Preferably the heat source or beam is held fixed and the part mounted on a movable table.

Abstract: An injection mold for forming a pattern for use in investment casting having mold sections carrying two pattern-forming surfaces and a translatable third pattern-forming element movable on a mold section. The mold also includes an inner core. Parting lines are located at inconspicuous locations by sizing and shaping the mold sections. The method of use of the injection mold includes employing an arrangement for facilitating lower mold section and for raising the inner core to facilitate its removal.

Abstract: A muzzle-loading firearm having a bolt, a receiver, a striker mounted in the bolt and a breech plug or other part of the receiver carrying a percussion cap in which the bolt has an extension engageable with the breech plug to prevent inadvertent engagement of the striker and percussion cap when the plug is not properly seated. Further, the bolt extension may prevent bolt locking when the plug is not properly seated.

Abstract: A golf club part including a metal component requiring subsequent finishing steps after initial formation which part as photo chemically engraved artwork formed in its surface after completion of the finishing step. The method of fabrication and etching of the metal part includes application of photoresist material to the metal surface, use of graphic art film, masking of surface areas in which artwork will be created by subsequent photochemical engraving, thereafter stripping of the photoresist from the metal surface. Creation of customized patterns on graphic art films is accomplished utilizing a programmable computer.

Abstract: A lever action firearm having a receiver, a hammer, a lever pivotal about a fixed point, a bolt and a link which link is pivotal on both the bolt and the lever. The pivotal lever includes first surface means to engage second surface means on the hammer to cause the hammer to be cammed back during unloading. The lever, link and bolt are configured such that when they are in the fire position and are subjected to forces of firing they function as a joint lock to prevent unloading of the bolt and lever. Locking surfaces on the receiver and bolt strengthen the joint lock at the moment of firing.

Abstract: A firearm frame constructed of plastic material having slide rail guidance members in the forward, central and rear portions of the frame. The frame is useful with a barrel unit which is cammed back and down by slide reciprocation and by a cam block which with barrel movement being arrested by the walls of a frame cavity. Forces and energy created in arresting such back and down movement of the barrel and block is transferred to the frame by the block hitting the frame cavity. A slide stop pin passing through openings in the frame and cam block also assist in transferring energy to the frame. Forces causing the slide to move upward during the arresting of barrel and block is prevented buy the rail guidance members. The trigger rotates about a trigger trunnion located in such frame cavity below the cam block.

Abstract: An autoloading firearm having a reciprocating bolt, a cocking lever and firing pin which bolt and firing pin are locked by a locking lever until the trigger is pulled or until the cocking lever of the bolt is manually pulled back. A linkage operably controlled by the trigger causes the locking lever to unlock the bolt and firing pin when the trigger is pulled.

Abstract: A method of manufacturing a firearm part and the part so manufactured in which the part is molded in a mold having secured therein an insert unit and after demolding a portion of such insert unit is removed to create an identification surface.

Abstract: A firearm having a laser beam capacity for aiding in sighting positioned within the firearm for adjustment therein and having an on-off switch operated by the firearm operator's trigger finger of the trigger finger hand is in position on the firearm grip. The switch can be assembled for operation by finger pressure from a selected side of the firearm.

Abstract: A device or arrangement for automatic firearms in which a transverse rotatable element is mounted in the slide is operable to move by camming action the firing pin partially forward to avoid being struck by the hammer, all prior to its further functioning to rotate the sear to release the hammer. The device also prevents further movement forward of the firing pin during rotation and the device may include means to hold it in its firing-pin-forward position.

Abstract: An elongated configured spring which biases the trigger bar of a pistol rearwardly and upwardly and engages the slide top latch to prevent its transverse movement. The spring is anchored in the frame and trigger bar under tension. The spring is long and narrow requiring little space in the firearm.
