This invention relates to a recording, device,

to engage aligned notches l9 formed in central

from rotating freely on shaft I2.

The above and other objects will appear more
fully from the following more detailed descrip
tion, and from the drawing wherein:

device as it appears on the instrument panel of

front portion of housing 20 to allow plunger I5
to project therethrough. The entire working or
leading edge of locking bar I4 is wedge-shaped

that same may engage notches I9 when the device
is in a locked position.
