Yes. Dienes patented that spring placement in 1936, and it shows up in many of their models into the 50s. Later on Dienes stopped tapering the strips and just made them rectangular.
Several manufacturers incorporate the "funnel" aspect of the wood strips with a more conventional spring placement. I have a Zassenhaus mill with a pair of funnel strips and side-mounted springs. KyM also used a similar setup on some mills—only they use two wood strips and just a single spring above the drawer.
It works...the strips put the grinds where you want them and cuts down on the mess inside the box. Eventually features like these disappear, presumably the result of value engineering efforts intended to strip unnecessary costs out of each unit.
(Here's a good example of value engineering at work: Note that the drawer opening on that 1936 mill above has rounded corners. That's because the front face is a single pice of wood, and the corner seams are only visible from the sides of the box. That looks better, because the seams aren't visible from the front. However, this construction method uses more wood, because the front piece is full-sized, then is cut to accommodate the drawer. If you can live with the corner seams facing the front, then the front piece of wood is only 2/3rds the length of the other pieces and you can simplify a production step. Hence, many of the box mills—and subsequent vintages of the same Dienes model pictured above—have forward facing corners.)
