Various devices have been developed for insertion through the chamber and into the barrel of a firearm to prevent the gun from being loaded by single shells or cartridges or the working of any of the various mechanisms which would bring a shell from the magazine to the chamber of an automatic firearm; see US. Pat. No. 3,137,957. Such prior art devices have at best suffered from the disadvantage of only being useful with one length of gun barrel and usually with no more than one cartridge head recess size. It is a primary object of this invention to provide a safety device that can be readily adapted to any length of firearm barrel or any size of cartridge head recess.
It is a further object of this invention to utilize a unique form of combination lock that greatly minimizes the possibility of removing the lock from a bead chain to which it is attached.
Other objects of this invention as well as features and advantages thereof will become more apparent from the following description and accompanying drawings, wherein:
FIG. 1 is a side elevational view of a phantom firearm showing the device of the instant invention positioned in the barrel thereof;
FIG. 2 is an expanded cross-sectional view of a portion of the bead chain;
FIG. 3 is an enlarged cutaway view of the combination lock of this invention arranged to receive the bead chain;
FIG. 4 is an enlarged cutaway view of the combination lock of this invention with the bead chain retained therein;
FIG. 5 is a cross-sectional view taken along the line 5-5 ofFIG. 1; and
FIG. 6 is an end view of the combination lock taken along line 6-6 ofFIG. 1.
Referring now to the drawings wherein similar characters of reference represent corresponding parts in each of the several views, the device of this invention is illustrated as being positioned in the barrel 10 and cartridge receiving chamber 12 of a firearm such as a conventional rifle (shown in phantom). The device consists of plug A, bead chain B and combination lock C. Plug A and lock C can be formed most readily of a hard plastic while bead chain B is most effectively formed of metal. Other materials will be apparent to one skilled in this art.
I More specifically, plug A includes a peripheral shoulder 14, tapered sleeve 16, base 18 and recess 20 for engaging flange 22 of chain connecting member 24. Chain connecting member 24 is in turn attached to one end of bead chain B by overlapping frictional engagement with outermost bead 26. As shown in FIG. 2, bead chain B comprises a plurality of beads 26 interconnected with links 28 having enlarged ends 30, chain B being formed in a manner well known to those skilled in the art.
Combination lock C is formed of body 32, pin 34, nose segment 36 and tumbler rings 38 interconnected so as to provide a torturous bead chain defining path 40 of a cross-section sufficient for insertion of bead chain B therethrough as hereinafter described. As shown most clearly in FIGS. 3 and 4, lock body 32 includes a series of parallel, spaced apart bores 42 within each of which is positioned a compression spring 44 and tumbler ratchet sphere 46. Body 32 is also provided with a chamber 48 for receiving the aforementioned pin 34. Also formed in body 32 are a series of parallel slots 50, preferrably aligned with the aforementioned bores 42 for receiving tumbler rings 38.
Referring now to FIG. 5, the interrelationship of one of the tumbler rings 38 to the remainder of the components of combination lock C is illustrated in greater detail. Thus, tumbler ring 38 includes a plurality of notches 70 spaced about the outer periphery thereof. In addition, ring 38 contains a single semi-circular groove 72 formed at a location opposite one of the notches 70. Notches 70 are arranged so as to interact with sphere 46 to lock ring 38 at various positions.
In operation, plug A is threaded onto the end of chain B having chain connecting member 24. Chain B is then inserted into barrel 10 from cartridge recess 12. Tumbler rings 38 are rotated by moving handles 68 so that each of the grooves 72 in respective of tumbler rings 38 is aligned with that portion of path 40 defined by aperture 62. When this is accomplished, bead chain B is inserted along torturous path 40 commencing from aperture 62" to 62 and out of the end of aperture 62. Bead chain B is drawn through combination lock C until tapered surface is drawn into rigid engagement with the end of barrel 10, as plug A is caused to abut recess 12. Tumbler rings 38 are then rotated by moving handles 68 so that grooves 72 are no longer aligned with opening 62. In this manner, bead chain B is prevented from being removed from lock C. Furthermore, bead chain B can only be removed when grooves 72 are again all realigned with aperture 62. As demonstrated in FIG. 6, by providing notches in each ring 38, corresponding to the numerals 1-9 and 0, and randomly forming each groove 72, there are 1,000 possible combinations of alignment of grooves 72 with three tumbler rings 38. Thus, without knowing the combination, lock C can only be opened after considerable manipulation of handles 68. Inclusion of further tumbler rings in the combination lock each expanding the possible combinations by a factor of 10.
Plug A can be formed in a range of sizes to occupy various gauges and calibers of firearms. Furthermore, member 24 can correspond to the cartridge recess opening of a 22 caliber firearm so that it can in and of itself be employed as the plug. Tapered sleeve 16 is provided with a 1 slope to ensure a tight fit within recess 12. Member 24 is provided with a similar slope for insertion into the cartridge recess of a 22 caliber firearm.
Although one embodiment of this invention has been described in detail, it will be apparent to those skilled in this art that the invention is only limited by the scope of the appended claims.
