ELECTRIC CLOCK MOUNTING APPARATUS Filed May 2, 195a INVENTOR. EILERT E.HJELSETH,JK
Generally speaking, the present invention relates to the electric clock art and, more particularly, pertains to i an improved apparatus for quickly and easily physically mounting an electric clock with respect to a vertical surface, such as a wall or the like, and for simultaneously removably electrically connecting said clock to an electric power supply circuit within 'said wall. H
Thus it can be seen that the apparatus of the present invention eliminates the prior artproblem of physically mounting an'electricclock on a wall andalso the prior artproblem of arranging to electrically connect a clock with respect to an electric power supply circuit, which is usually accomplished by. extending an electric cord consisting of two wires to the nearest electric Wall outlet. This-is disadvantageous for several reasons First, the nearest electric wall outlet may be located a sub sta-ntial distance away from the location where the electric clock is to he mounted onf a wall and thus require a lengthy extension cord Furthermore, such an 'extem sion cord is both unsightly and may become accidentally disconnected or cause other accidents because :it is inthc way. d
Furthermore, the prior art method of physically mounting such an electric clock on a vertical wall'usually requires the insertion of a screw into the wall and the consequent marring of the wall surface. 7
It should be noted that the present invention cornpletely solves all of the above-mentioned prior art ,problems, since no physical fastener must be screwed into the plaster of the wall, and consequently mar-ring-of same is not necessary, and since no extension cord to provide electrical connection is required. In other words, the S clock of the present invention can be very easily and quickly, both physically and electrically, mounted or dis mountedwith respect to a wall'surface at apredetermined location. a a A With the above points in mind, it is an object of the present invention to provide irnprovedmeapsfor removably physically mounting an electricclock in' front of a vertical wall while simultaneously removably electrically connecting said clock to an electric power supply circuit within said wall. v
