| 201 | Wraparound cover for guns during field use | US142193 | 1988-01-11 | US4860479A | 1989-08-29 | Michael D. Easter |
| A new protective covering device (14) for guns (16) with telescopic sights providing protection for the telescopic sight, trigger and action while the gun (16) is being carried in the field. The covering device (14) is comprised of a single expanse of flexible waterproof material (14) having sufficient size to envelop the midsection of a gun (16), to include the telescopic sight, action and trigger. Attached to the flat upper edge of flexible material (4) are one or more straps (10A, 10B) extending outward and having a releasable connector device (8) attached to the free end providing means for attaching the covering device (14) to the telescopic sight of a sun (16).Integral with the lower portion of the covering device (14), is an elastic member (6) defining a circuitous and somewhat encircling route adjacent to and parallel with a skirted edge (12). As the covering device (14) is wrapped around and closed over the midsection of a gun (16), the integral elastic member (6) is stretched into tension and provides a retaining and sealing of the flexible material (4) about the weather sensitive midsection of a gun (16). The skirted edge (12) participates in providing the desired protection while conveniently serving as a means for the user to grasp the covering device (14) in order to open and close the covering device (14). | ||||||
| 202 | Lock cover for muzzle loading rifles | US166088 | 1980-07-03 | US4328634A | 1982-05-11 | James W. Wiltrout |
| An inverted generally channel-shaped member is provided for downward embracing engagement over the stock of a flint lock mechanism equipped muzzle loading rifle having its flint lock mechanism supported from one side of the rifle stock. The channel member includes opposite side depending first and second flanges interconnected by an upper bight portion extending and secured between the upper marginal edges of the side flanges and the bight portion includes an opening in vertical registry with the flint lock mechanism. The bight portion includes an opening formed therein in vertical registry with the flint lock mechanism and a top wall portion is supported from the channel member for swinging movement into and out of closing relation with the opening. When the top wall portion is in the closed position, the flint lock mechanism is at least substantially fully enclosed within the channel member and thus protected from the elements and when the top wall portion is in the open position free access to the flint lock mechanism is provided from above. The opening and top wall portion are spaced to the same side of the longitudinal center line of the rifle on which the flint lock mechanism is disposed. | ||||||
| 203 | Closing device for the slot through which passes the cocking lever of automatic weapons | US870186 | 1978-01-17 | US4145831A | 1979-03-27 | Maurice V. Bourlet |
| Closing device for the slot through which passes the cocking lever of automatic weapons, the slot being provided in the casing of the latter, characterized by the fact that it is mainly made up of: a shaped flap provided with a cut-out portion at each of its ends; two posts which are integral with the casing and pass through each of aforesaid cut-out portions; and a spring hooked by its ends onto aforesaid posts and attached in its center to aforesaid flap, so as to press the latter against the casing and to stress it towards its closing position of the slot. | ||||||
| 204 | Rotary port cover | US690518 | 1976-05-27 | US4044487A | 1977-08-30 | James C. Hutton; Thomas G. Bauman; Kenneth C. Rowlands |
| An ejection port cover for a firearm which moves in pure rotation about an axis parallel to the bore of the firearm. The port cover is held about this axis and is oriented in the "open port" and "closed port" rotational position for proper alignment of a port cover cam with associated cam pin means on the reciprocating slide assembly since the port cover is shorter than the stroke of the slide assembly that engages and causes rotation of the port cover. | ||||||
| 205 | Machine gun having trigger group | US3731588D | 1971-11-22 | US3731588A | 1973-05-08 | CURTIS G; TATRO H |
| The machine gun of this invention features a bolt assembly reciprocably mounted within a receiver and removably maintained within the receiver by a single latch mechanism, and a fire control group supported for reciprocation on the receiver between a forward charging position and a rear firing position, the fire control group including a sear releasably holding the bolt assembly in cocked condition, the fire control group having a releasable latch and a trigger pivot shaft mounted for movement laterally of the receiver and serving as a safety when the fire control group is in rear firing position.

| 206 | Lockless firearm system | US3713240D | 1970-06-05 | US3713240A | 1973-01-30 | GOLDIN M |
| A firearm breech comprising a cylindrical breech section with a chamber cut through it to form a slot between a pair of straps which are integral with the portions of the firearm at the axial ends of the chamber. The chamber may be closed by an axially slidable sleeve which also thereby encloses the straps; the structure results in the elimination of all conventional gun locking structure.

| 207 | Round extractor for caseless firearm | US3628277D | 1969-07-18 | US3628277A | 1971-12-21 | PLUMER ROY D; SHROUT HAROLD |
| An extractor for removing a round of caseless ammunition from the chamber of a firearm capable of firing caseless ammunition. The extractor comprises an elongated spring steel member having a forked end providing a pair of spaced spring fingers which are adapted to embrace the molded propellant of a round of caseless ammunition. The elongated spring steel member is slidably supported by a guide block mounted on the exterior of the firearm and the spring steel member can be axially projected into a position where it grips the round of caseless ammunition and then moved back to withdraw the round from the chamber of the firearm. The spaced fingers of the extractor are formed with beveled edges which permit the extractor to slidably engage the molded propellant of the caseless round when the extractor is being moved forward but include a sharp edge which bites into the caseless round to form a means for withdrawing the round from the chamber when the extractor is pulled back. The firearm has an opening which is closed by a pivotally mounted door and the extractor is arranged to move the door to an open position and grip the caseless round of ammunition, when the extractor is projected into the chamber to grip the round of ammunition. The door is spring biased toward a closed position, and when the extractor is moved back to the position outside of the chamber, the door is returned to the closed position.

| 208 | Protective cover means for firearms | US3574965D | 1969-01-23 | US3574965A | 1971-04-13 | SEIGER RICHARD H |
| New and improved stock covers for firearms, which covers can remain installed even while the firearm piece is being fired. The subject covers protect particularly exposed areas of the stock from marring as by hitting objects, falling of the firearm piece, and so forth. The stock covers of the invention include suitable openings to provide relief or access areas for certain functional portions of the firearm, and, additionally, means such as flaps and straps for ultimately securing the covers in place. The covers are so designed that side areas of the stock of the firearm are especially protected against damage.
