The core of the mechanism is also removable UNITED STATES PATENTS by the owner in order to provide quick key changes. 3,089,272 5/1963 McKinley ..42/l N 2 Claims, 6 Drawing Figures FIREARM LOCK This invention relates to locking devices for shoulder-type firearms which will prevent them from being fired.

It is therefore the primary purpose of this invention to provide a firearm lock which will be adjustable so as to fit the ejection ports of shoulder arms of various gauge sizes.

Another object of this invention is to provide a locking device which will have a slide bolt which will be adjustable in length, and when used in combination with a slideable body portion of the device will make the firearm lock adaptable to any size ejection port of a shoulder arm.

A further object of this invention is to provide a firearm lock which will have a wire loop lanyard, the lanyard providing a means of securing the firearm lock on any convenient rod or the like.

Other objects of the present invention are to provide a firearm lock which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.

These and other objects will be readily evident upon a study of the following specificationand the accompanying drawing wherein:

FIG. 1 is a plan view of the present invention shown installed within the ejector port of a shoulder firearm which is shown in phantom lines;

FIG. 2 is an enlarged plan view of the invention shown removed from FIG. 1;

FIG. 3 is a side view of FIG. 2 shown in elevation with the extended portion of the bolt shown in phantom lines;

FIG. 4 is a left end view of FIG. 3;

FIG. 5 is a right end view of FIG. 3; and

FIG. 6 is a bottom plan view of FIG. 3 which is shown partly broken away.

According to this invention, a firearm lock 10 is shown to include a plate 11 which is spot welded to tabs 11 of a member which hereinafter will be described.

It shall be noted that an outwardly extending tongue 13 of lock 10 serves to engage the forward interior of the ejection port of the shoulder firearm.

A gasket 12 is provided with an opening 14 in which the hollow main body 15 is carried. An opening 16 through plate 11, receives the lock cylinder 17 and the bolt 18 of lock cylinder 17 includes a size spacer 19 which is adjustable by means of screw 20. The adjustability is achieved by the varied thicknesses of spacer 19 which is secured by screw 20. The tabs 11 of the main body 15 are spotwelded to plate 11 of device 10.

Cylinder 17 is secured within the hollow main body 15 by means of a set screw 21. A slideable internal member 22 is provided with an elongated slot 23 which carries a serrated screw 24, screw 24 being threaded into one side of the main body 15.

It shall be further noted that the slideable member 22 includes the tongue 13 and allows lock 10 to be adaptable to ports of various sizes thereby increasing the versatility of firearm lock 10. Once the proper length is determined, the screw 24 is then tightened.

It shall also be noted that the principal purpose of firearm lock 10 is to provide a means of locking the ejector port of a shoulder firearm and a loop lanyard 25 may be secured in a suitable manner (not shown) to the face plate 11 to allow firearm lock 10 to be secured on a rod or the like, if desired.

It shall even further be noted that the use of lanyard 25 is optional and the high sidewalls of elements 15 and 22 will always be at the bottom of the ejector port opening in order to prevent entry to the operating parts of firearm lock 10 from the bottom of the shoulder firearm.

What I claim is:

l. A key-operated firearm lock for blocking the ejector port of a firearm, comprising an elongated face plate, a lock cylinder carried within said face plate with slideable and adjustable bolt means for blocking said port of said firearm, a hollow main body carried by said face plate, a sliding and hollow secondary body carried by said firearm lock for lockinlg a firearm of various gauge size and means for securing said s rding secondary body to said main body, a gasket of similar shape as said face plate being carried on said main body, said slideable secondary body having a tongue extending outward for providing a means of engaging the interior of the forward portion of said ejector port opening of said firearm and in combination with said bolt and said lock cylinder, said firearm lock thus being rendered stationary within said ejector port, said face plate preventing tampering with said firearm and preventing it from being fired after said key is inserted into said cylinder to extend said bolt of said cylinder outwards within said ejector port, said main body and secondary body being hollow and provided with one sidewall which is higher than another sidewall, said sidewall being at the bottom of said ejector opening in order to prevent entry to said firearm locks mechanism from a bottom of said shoulder firearm and set screw means on the interior of said firearm lock allowing Said slideable member stationary after being adjusted in length for fitting a desired shoulder firearm, said set screw being freely can-ied within an elongated slot of said slideable body member, and said set screw being threadingly received within one sidewall of said main body of said fireann lock, and said mechanism having a core that is removable by an owner in order to provide quick key changes.

2. The combination according to Claim 1, wherein said lock cylinder is secured within said main body of said firearm lock by means of a set screw through one of the sidewalls of said main body and the bolt of said cylinder is provided with a slideable size spacer which is adjustable by means of a set screw member and said lock includes a loop wire lanyard for securing it to a rod or the like.
