3 Claims. (Cl. 42-1) The present invention relates to a locking device for use in association with a firearm, for locking the firearm against inadvertent discharge and against tampering by .persons unauthorized to use the same.
l An object of the present invention is to provide a firearm locking device of the character described which may be easily and quickly assembled with a firearm for locking the same and just as easily and quickly removed therefrom by the person in possession of the key thereto. It is also an object of the present invention to provide 'a firearm locking device of the character described which is firmly and securely fixed and held in place upon the firearm to render it undischargea'ble and is substantially proof against removal without a key and against tampering even with the use of force.
Itis another object of the present invention to provide a firearm locking device of the character described which` will permit the ventilation of the barrel of the firearm, even when locked in place thereon, to prevent sweating and resulting rusting and deterioration of the firearm barrel.
It is a further object of the present invention to provide a firearm locking device of the character described which is of relatively simple construction and relatively economicalto produce and simple to use, to thereby make its adoption and use economical and practical and thereby greatly reduce destruction of life incidental to accidental and unauthorized use of the firearm.
The foregoing and other objects and advantages vof the firearm locking device of the present invention will become more readily apparent to those skilled in the art from the embodiments thereof shown in the accompanying drawing and from the description following. It is to be understood, however, that such embodiments are shown by way of illustration only, to make the principles and practice of the invention more readily comprehensible, and without any intent of limiting the invention to the specific details therein shown.
In the drawings:
Fig. 1 is `an elevational view of one embodiment of a firearm locking device of the present invention;
Pig. 2 is an elevational and partly sectional view of the firearm locking ydevice of Fig. 1; shown as mounted in locking position upon a revolver;
Fig. 3 is a fragmentary, sectional land partly elevational view showing the firearm locking device of the present invention as used in association with a rifle;
Fig. 4 s a section taken on line 4--4 of Fig. 2; and
Fig. 5 is a section taken on line 5--5` of Fig. 3.
Referring now in greater detail to the illustrative embodiments of the invention shown in the accompanying drawing, the locking device of the present invention cornprises a cylinder lock 10, disposed in a housing, generally designated as 12. The housing comprises a solid metallic block 14, of any suitable metal conventionally used for the purpose, of preferably circular cross section and preferably thickest at a central point of its length from which it tapers toward each end, to provide iCC an outer surface that will tend to deflect any hammer or like blows that may be applied for lock breaking or removing purpose.
The inner portion of the housing lblock 14 is formed with a preferably centrally disposed longitudinally extending cylindrical bore 16, adapted to t snugly over the end of the barrel 20 of a firearm, such as a revolver 22, with which it is intended to be associated, and the Wall of the lbore 16 is provided at the top thereof, with a slot 24, extending longitudinally inwardly to a point short of the inner wall 26 of the bore 16, to accommodate the firearm sight 28, near the end of the barrel 20. The length of the (bore 16 and slot 24 are relatively such that when the end of the slot 24 abuts the outer end of the sight 28, the end of the barrel 20 which is fitted into the 'bore 16 will terminate short ofthe inner Wall 26 of the latter, to leave an air space 30, at the inner end of the bore 16, in the wall portion of which are formed a plurality of radially extending air admitting apertures 32.
A cylindrical bore 34, of lesser diameter than the bore i 16, is formed in the outer portion of the housing block 14, communicating with the bore 16 but slightly eccentric relative thereto in a direction diametrically opposite the slot 24, in which is accommodated the lock cylinder 10, which may be of any conventional tumbler type, hav- 1 ing a key rotated central rod or core, but preferably of a type from which the operating key 36, may not be removed when the lock is in open position. Such locks are conventional and not thought necessary to be shown in detail.
Secured within the bore 16, by one end thereof, is an v j, bore 16, in any suitable manner, as against the inner wall 26 thereof, so that it is eccentric to the cylinder lock 10. The sleeve 40 is preferably provided with fiutings 42, on its outer surface which permit the circulation and passage of air from the space 30 into the interior of the -barrel 20 into which the sleeve 40 is inserted. Preferably, the iiutings 42 may be interrupted or broken at spaced intervals of their length, to permit improved air circulation by permitting passage or interchange of air between` the several fiutings 42.
A metal rod 44 is disposed within the sleeve 40, its
inner end suitably and operatively connected to the rodv of the cylinder lock lll, so that the rod 44 is eccentrically disposed Within the sleeve 40. The rod 44 is coextensive in length with the sleeve 40 and extends slightly .beyond it and has mounted eccentrically on its outer end,
exteriorly of the sleeve 40, and flush against its end a metallic disk 46.
The sleeve 40 may be of any desired length suitable for the particular firearm for which it is to be used. Thus in the revolver illustrated, the sleeve is of sufficient length to extend inwardly through the barrel 20 and through a registering chamber 48, of the revolver cylinder 50, so that when the locking device is placed in position upon the end of the barrel 20', the inner end of the sleeve 40 will terminate co-extensively with the inner end of the revolver cylinder 50, Iso that when the key 36 is turned to locking position the rod 44 will be rotated to move the cam disk 46 from position of register with the end of the sleeve 40 into an eccentric position out of register therewith and into engagement with the inner face 52 of the revolver cylinder 50, whereby the locking device becomes securely engaged upon the revolver to prevent rotation of the cylinder 50 and the firing of any of its bullets. It is to be understood, of course,
