FIREARM LOCK
Abstract
A locking mechanism for placement into the ejection port of a
gun. The device when placed into the port of the gun is
key-operated to prevent the removal of the device and will not
allow the gun to be fired until it is removed therefrom. The device
is also of such structure so that it cannot be forced out of the
port. The core of the mechanism is also removable by the owner in
order to provide quick key changes.

Claims
What I claim is:
1. 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 locking a firearm of various gauge
size and means for securing said sliding 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 carried
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 firearm 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.
Description
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 specification and 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.
