Publication number: 20140047788Abstract: A surface covering unit includes at least one face comprised of at least one primary rotational tessellation element. The rotational tessellation element includes at least two pairs of sides, and the sides in each pair of sides have the same length and are images of one another. The sides of a first pair of sides extend from a first vertex and are rotationally spaced from each other, and the sides of a second pair of sides extend from a second vertex and are rotationally spaced from each other. The sides of the first and second pairs of sides have two or more straight line segments or complex curves, and are not a single straight line or a single curve. One pair of sides has a length different from the other pair of sides. The surface covering has a natural appearance such that a repeating pattern is not readily apparent.Type: ApplicationFiled: October 11, 2013Publication date: February 20, 2014Applicant: Keystone Retaining Wall Systems LLCInventor: Thomas S.

Publication number: 20140048964Abstract: A floating cut-off bar coupled to a feed drawer whereby a mechanism allows the floating cut-off bar to engage the specified contour of side rails and a division plate in a mold box assembly and aid in material distribution by screeding excess material and delivering additional material to areas of the mold box as necessary and method of making wall blocks therefrom. The specified contour of the side rails and optionally division plate is designed to optimally deliver material to achieve a specified uniform density of the block produced for greater structural integrity, strength and durability of the block.Type: ApplicationFiled: October 28, 2013Publication date: February 20, 2014Applicant: KEYSTONE RETAINING WALL SYSTEMS LLCInventors: David M. LaCroix, Robert A. MacDonald

Patent number: 8609215Abstract: A surface covering comprises multiple units adapted to mate with one another and cover a surface. Each said unit comprises at least one primary rotational tessellation element that defines the sides of the unit, has an irregular configuration, includes a face having molded surface irregularities or variations therein, and has at least two pairs of irregularly shaped sides. Preferably, gaps of variable width are defined between visible edges of adjacent units in the surface covering. The surface covering has a natural appearance such that a repeating pattern is not readily apparent. A structural wall unit system is also provided.Type: GrantFiled: September 25, 2012Date of Patent: December 17, 2013Assignee: Keystone Retaining Wall Systems LLCInventor: Thomas S. Riccobene
