I brought home a Clausing 1300 lathe (13" x 36") that has a somewhat
peculiar cross slide. There is a main cross slide, with the normal
power cross feed, but instead of a normal compound on top, the main
side has T slots towards the front and rear. A regular Aloris tool
post is attached with a small base plate bolted down to the T slots.
Since It appears this is the way the machine was made, what was the
main use for such an adaptation?

It allows you to set up two independent tools on the carriage, very
common on ram-type turret lathes. This pic shows a typical setup with
a turning tool on the front and a cutoff on the back.
