This invention relates to a reversible fork, rake,
or hoe.
An object of this invention is the provision of
simple and efficient means for adjusting a tool
for use as a fork, or a rake, or a hoe.
Another object of the invention is to reduce
to a minimum the number of parts of a reversible
or convertible tool.

pointed end of the spur I3 rides down the in

movement of the head I, as the spur assumes its
complete seated position, as shown in Figure 4;

A still further object of the invention is the
