An electric plug lock is provided for preventing the unauthorized use of an electrically operated appliance which has an electrical cord and plug. It operates by isolating the electrical prongs of the plug in a two part container and then locking the parts together with a conventional padlock.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Turning now descriptively to the drawings, in which like reference characters denote like elements throughout the several views, FIGS.
1 and 2 illustrate an electrical plug 11 and an electrical plug lock 10 for use for security purposes.
In FIG.
1 plug 11 is attached to cord 12 which can be attached to any electrical appliance (not shown).
The electrical plug lock 10 is generally comprised of two parts 14 and 16 respectively: a closure member 14 integrally formed of one piece has a circular back portion 22 with an elongated slot 20 through which an electrical cord 12 can be inserted.
A tongue 24 projects from the circumferential edge 30 of back portion 22, opposite the elongated slot 20, at a right angle to the surface 32 of back portion 22.
At the extreme end of the tongue 24 is a hole 26 through which the shackle 28 of a conventional padlock 18 maybe passed through.
A cylindrical housing 16 has an open end 18 into which back portion 22 of closure member 14 just fits.
The opposite end of housing 16 is closed by a wall 34 and has a bore 36 through which tongue 24 protrudes when the instant invention is assembled.
In operative use it will be seen, as shown in FIG.
2, that when the two components i.
e.
closure member 14 and cylindrical housing 16 are assembled that an electrical plug 11 may be encaptured inside of the electrical plug lock 10 and locked therein in such a manner that the plug cannot be removed therefrom except by first removing lock 18.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing from the spirit of the invention.
