Plane Dissection, Nine triangles,four quadrilaterals, one pentagon, and one hexagon which are arranged as a pentagon.
Geometric Model - Plane Dissection by A. Harry Wheeler, with Pieces Arranged as Pentagon, Square, and Hexagon
Description:

The fifteen pieces of this dissection fit into a pentagonal box with a wooden base, plastic sides and top, and paper lining. The pieces can be arranged as a regular pentagon, a square or a regular hexagon.

The pattern is first in 1979.3002.43 (folder 1).

Drawings of triangle-square-pentagon (14 pieces), triangle-square-pentagon-hexagon (26 pieces), square-pentagon-hexagon (15 pieces), triangle-square-hexagon (13 pieces)dated December 21, 1931 are in 1979.3002.43, folder 3.
