US Patent 3,955,602 (Robert W. King, assigned to Avco Corporation, granted 11 May 1976) describes a loom-like apparatus that uses needles to weave filaments along the X and Y axes into a bundle of Z-axis filaments, producing a three-dimensional woven block. The structure is held together by inter-yarn friction, compressed, then impregnated with resin or another matrix and cured into a billet that can be machined. The document includes a web-printed copy of the patent record, the original patent drawing sheets (8 figures, including a cylindrical variant), and the typeset specification and claim.

US Patent 4,001,478 (granted Jan. 4, 1977) to Robert W. King, assigned to Avco Corporation, describes three-dimensional woven filamentary materials and the looms used to make them. Filaments on a Z axis are woven with X-axis and Y-axis filaments, compressed so inter-yarn friction holds the structure together, then impregnated with resin or another matrix and cured into a machinable composite billet. The patent describes a rectangular needle loom and a cylindrical weaving apparatus built from wound slats on a mandrel. It includes the claims, the description, and four sheets of drawings (Figs. 1-8). The scan contains both a USPTO web printout and the original patent print.

US Patent 4,038,440 (1977), granted to Robert W. King of Avco Corporation, describes a method and product for making three-dimensional woven filamentary material. Filaments in the Z axis are interlaced with X and Y filament layers in close touching contact, held together by inter-yarn friction. The block is then compressed and impregnated with plastic or resin and cured into a billet that can be machined. The document includes the USPTO database printout, the claims and description, and the patent drawings of the apparatus and the impregnation setup.
