Abstract
Abstract An assembly of a multiplicity of thin wood boards each having parallel grooves in one face from edge to edge thereof, and the opposite face being ungrooved, is held together by one or more rods extending through the several boards, the grooved face of each board facing the smooth face of an adjacent board. At the ends of the assembly, cupped spring plates engage the outermost surfaces of the boards and nuts threaded on the rod ends apply pressure on the plates to hold the board surfaces in contact. There is a flexible thin strip of adhesive covering one end of each of the grooves and adhered to the board edges at that end of the grooves and to the adjacent side edges of the boards.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
161 words
A nesting structure for wild bees, comprising: a plurality of parallel engaging wooden boards forming a stack; a plurality of parallel grooves formed in one side surface of each board running from one side edge of the board to an opposite side edge in the direction of the wood grain; wherein the remaining side surface of each board is planar and ungrooved with each grooved surface resting against a planar side of an adjacent board to form a plurality of closed channels opening at opposite ends of the stacked boards; an aperture formed through each board from the grooved surface to the planar surface forming an open bore extending through the stack; a supporting rod received through the open bore with ends protruding from the stack; spring clamp bars at the rod ends for engaging the stack at opposite ends thereof; and means on the rod for deflecting the spring clamp bars against the stack ends to secure the boards therein.
Claim 2
Dependent Claim
161 words
A nesting structure for wild bees, comprising: a plurality of parallel engaging wooden boards forming a stack; a plurality of parallel grooves formed in one side surface of each board running from one side edge of the board to an opposite side edge in the direction of the wood grain; wherein the remaining side surface of each board is planar and ungrooved with each grooved surface resting against a planar side of an adjacent board to form a plurality of closed channels opening at opposite ends of the stacked boards; an aperture formed through each board from the grooved surface to the planar surface forming an open bore extending through the stack; a supporting rod received through the open bore with ends protruding from the stack; spring clamp bars at the rod ends for engaging the stack at opposite ends thereof; and means on the rod for deflecting the spring clamp bars against the stack ends to secure the boards therein.
Claim 3
Dependent Claim
52 words
The wild bee nesting structure as defined by claim 1 further comprising: a flexible sheet covering the open channels at one end of the boards; and an adhesive securing the flexible sheet to the one end of the boards to prevent communication between the groove at said one end of the boards.
Claim 4
Dependent Claim
109 words
The device defined by claim 1 wherein said spring clamp bars are formed of resilient curved steel bars having concave faces facing end boards of the stack and receiving the supporting rod through apertures therein; and wherein said means is comprised of: a head on one end of the rod against a convex side of one bar; an opposite end of the rod being threaded to receive a nut; and a nut threaded on the rod at said opposite end to force the bars toward each other and flex the bars against the stack therebetween bias the boards together to prevent communication between the grooves at the side surfaces.
Claim 5
Dependent Claim
35 words
The device defined by claim 2 wherein the flexible sheet material comprises a metal foil with an adhesive coated over one entire side surface thereof to enable adhesion to an entire side of the stack.
