portions of the back section 6. The inner or free
15 end of each guide member I 9 has secured thereto
a shouldered pin 22, which travels in the adjacent

It will now be observed that the guide members

the slot and pin connection, so that when-the
sections are fully extended with the pins 22 po

25 the pins as a pivot, until the sections assume a
more or less tilting or angular position krelative
to each other as clearly illustrated in Figure 8
and by broken lines in Figure 3.

movement of the lug 28 through the medium- of
