Those are track ends.

Besides being used on track bikes these dropouts (that aren't technically dropouts) were also used on coaster bikes and 3 speeds.

The simple lugwork and pressed ends suggests that it was an entry level model but it still could be turned into quite a nice ride and that fork appears to be chromed.

It would be nice to see the rear with a wheel mounted up to see what kind of clearance the bike has... 27 inch tyres would seem to be the logical choice for a bike that is this well aged.
