Definitions

  • Patent 4,538,37l issued on the 3rd day of September l985; by Mears in U.S. Patent 4,570,37l issued on the l8th day of February l986; and by Csongor in U.S. Patent 4,574,5ll issued on the llth day of March l986.
  • an object of the present invention to provide an improved magazine charger which is substantially free of one or more of the disadvantages of prior chargers. Another object is to provide an improved magazine charger which is inexpensive to manufacture.
  • Another object is to provide an improved magazine charger which can be employed to quickly and efficiently charge cartridges to a magazine.
  • Still another object is to provide an improved magazine charger that can be operated by a single individual.
  • Yet another object of the present invention is to provide an improved magazine charger which is especially useful with 9mm cartridges.
  • An additional object is to provide a magazine charger that functions smoothly when used with a magazine having two rows of cartridges which are side-by-side.
  • a magazine charger comprising a body, a plunger, and a plunger spring.
  • the body has an open end which constitutes means for receiving a magazine to be charged with cartridges.
  • the magazine has a magazine spring.
  • the body further comprises a closed end which is opposite the open end.
  • the closed end of the body has a passage with outwardly flared sidewalls.
  • the plunger is axially, slidably carried in the passage in the closed end of the body of the charger.
  • the plunger is adapted to move cartridges against the magazine spring.
  • the plunger spring biases the plunger away from the open end of the charger.
  • the plunger is operable to sequentially depress the uppermost cartridge thereby facilitating feeding of cartridges to the magazine.
  • the charger l0 is especially useful for charging 9mm cartridges to a magazine l2.
  • the charger l0 comprises a body l4, a plunger l6 and a plunger spring l8.
  • the body l4 is constructed of a single piece of resinous thermoplastic.
  • the body l4 has an open end 20 and a closed end 22 (see Figure 4).
  • the open end 20 constitutes means for receiving the magazine l2.
  • the charger l0 of the present invention is adapted to be used with a conventional well-known magazine l2.
  • a magazine l2 there is a cartridge follower 26 which is biased toward the open end of the magazine l2 by a magazine spring 24.
  • the magazine l2 is equipped with a magazine spring 24 which upwardly urges a cartridge follower 26.
  • the magazine l2 terminates in a left lip 28 and a right lip 30.
  • the lips 28, 30 are juxtaposed with respect to each other; they are cartridge-retaining lips which keep the cartridges within the magazine. In order to perform this function, they are spaced from each other a distance less than the diameter of a single cartridge such as the cartridges 32, 34.
  • the body l4 carries legs 36, 38.
  • the distance "d" (see Figure 5) between the legs 36, 38 is less than the width of the magazine l2. This causes the legs 36, 38 to tightly and firmly grip the magazine l2.
  • the body l4 of the charger l0 also carries a fixed saddle 40 the surface of which is lower than the cartridge-retaining lips 28, 30 of the magazine l2 (see Figures 9 and l0). As explained more completely below, insertion of a cartridge, such as the cartridge 34, into the magazine l2 causes the cartridge 34 to slide along the fixed saddle 40 while remaining out of contact with the lips 28, 30.
  • the plunger l6 comprises a shaft l7 of given width "w".
  • One end of the shaft l7 is fixedly attached to the top 48.
  • the top 48 has a diameter "L” which is far greater than the width "w” of the shaft.
  • the other end of the shaft l7 is fixedly attached to a plunger-­saddle l9.
  • the width "s" of the plunger-saddle l9 is slightly greater than the width "w" of the shaft l7.
  • the plunger l6 is axially slidably carried by the closed end 22 of the body l4 (see Figure 3). Furthermore, as shown in Figures 9 and l0, the plunger l6 is adapted to move cartridges such as the cartridges 32, 34 against the magazine spring 24. Thus, the plunger l6 is operable to sequentially depress the uppermost cartridge 32, or 34 facilitating the feeding of additional cartridges to the magazine l2. The plunger l6 contacts the uppermost cartridge 32 behind the forward edge of the cartridge-retaining lips 28, 30. The plunger l6 has a stroke which is greater than the diameter of a single cartridge, such as the cartridge 32, in order to depress the cartridge 32 downwardly a distance sufficient to insert a cartridge such as the cartridge 34.
  • a typical 9 mm cartridge 32 such as the cartridge 32, comprises a projectile 42 held in a casing 44.
  • the casing 44 is provided with an extractor recess 46 and a rim 47.
  • the closed end 22 of the charger l0 has a plunger-receiving passage 52.
  • the passage 52 comprises a planar left sidewall 54 and a planar right sidewall 56.
  • the left sidewall 54 has a top edge 58 and a linear bottom edge 60.
  • the right sidewall 56 has a top edge 62 and a linear bottom edge 64.
  • the sidewalls 54, 56 are outwardly flared such that the distance "t” between their top edges 58, 62 is greater than the distance "b” between their bottom edges 60, 64. Furthermore, the distance “b” between the bottom edges 60, 64 of the sidewalls 54, 56 is slightly greater than the width "w” of the shaft l7 of the plunger l6. (See Figure 7). However, the distance “b” is slightly less than the width "s" of the plunger-saddle l9.
  • the passage 52 also comprises a planar back wall 66 joining the back of the left sidewall 54 to the back of the right sidewall 56.
  • a planar front wall 68 joins the fronts of the sidewalls 54, 56.
  • the plunger l6 is inserted in the plunger-receiving passage 52 by forcing the plunger-saddle l9 past the bottom edges 60, 64 of the sidewalls 54, 56.
  • the sidewalls 54, 56 expand slightly and the plunger-­saddle l9 contracts slightly until the plunger-saddle l9 passes beyond the bottom edges 60, 64, whereupon the plunger-saddle l9 and the bottom edges 60, 64 regain their original shape.
  • the plunger-saddle l9 then prevents removal of the plunger l6 from the passage 52.
  • the magazine charger l0 is employed to charge a magazine as follows. An empty magazine is first charged with a cartridge 32 in any convenient manner or in the manner described below. Thereafter, finger pressure is applied on the top 48 of the plunger l6 causing the plunger l6 to downwardly move a full stroke. At this point, the plunger spring l8 is fully compressed as shown in Figure l0. Furthermore, the first cartridge 32 is moved away from the saddle 40. It is also moved downwardly against the upward force of the magazine spring 24. This leaves a space 50 between the saddle 40 and the first cartridge 32. This space 50 is ideally adapted to receive a second cartridge 34. Next, a second cartridge 34 is manually inserted in the space 50 between the saddle 40 and the first cartridge 32. The second cartridge 34 is moved rearwardly until the rim 47 of the cartridge 34 lightly contacts the plunger l6.
  • the plunger l6 is no longer behind the cartridge 34.
  • the cartridge 34 is further manually inserted until the rim 47 of the cartridge 34 contacts the rear wall (not shown) of the magazine l2.
  • the plunger-saddle l9 can follow each cartridge whether the cartridge is in the left row as in the case of the cartridge 32 or in the right row as in the case of the cartridge 34.
  • the charger l0 of the present invention can be constructed of a wide variety of materials.
  • the charger l0 can be metal or plastic.
  • the preferred materials are resinous thermoplastics such as polypropylene or nylon. Nylon 66 is the most preferred material.
  • the charger l0 of the present invention can be employed with a wide variety of cartridges. However, it is especially useful with the standard 9 mm cartridge having an outside diameter of about 9.9 mm and having a length of about 27 mm. Such cartridges are too short to be manually charged to a magazine with any facility whatsoever.
