4. A parking coin depository comprising: a housing,‘
a guide attached to the housing, a slide mounted for
movement along the guide, the housing having a window

any coin in the passageway will drop to the level of the
slide and window, the guide being a track and there
being no obstruction between the passageway and the
track except for said surface.
5. The invention as de?ned in claim 4 wherein the
window is offset from the passageway, and the slide has
an end surface normal to said upper surface for pushing
a coin to the window.

6. The invention as de?ned in claim 5 wherein the track
extends below the window but is discontinued past one
edge of the window so that a coin may be pushed off
the track by the end surface.
7. The invention as de?ned in claim 6 wherein the

slide has a magnetic material attached to it, and the
housing has an opening in line with the movement so
that a magnetized key may be inserted through the open
ing and thus actuate the means mounted for movement.
