(19) With particular reference to the included Figs., an embodiment of the present invention generally comprises an apparatus of two support posts, each consisting of a top plate 14, a bottom plate 26, and a plurality of fasteners that secure the apparatus and allow for its adjustment. More specifically, an embodiment of the present invention may comprise an adjustable support post that is formed from one or more of the following: pieces of steel or other similar material that are cut to a length that form a top plate 14 and a bottom plate 26, and various fasteners.

(20) Now referring to FIGS. 1-13, that will be discussed together, there are shown components of a portable adjustable easel method and apparatus used to support a rigid material. In an embodiment of the present invention, a top plate 14 may have a center slot cut 32, into the body of the top plate 14. Some embodiments may have a tab 24 at one end of the center slot 32 in the top plate 14, while other embodiments may not have a tab at one end of the center slot 32. The top plate 14 may be made from steel or other similar material. A hole 16 may be drilled approximately midway along the long-axis of the top plate 14.

(21) After a bending process, the top plate 14 may be shaped with three curves and a fourth section may comprise the unbent remainder of the top plate 14. Accordingly, other embodiments may comprise a top plate 14 with sections of varying lengths. The center slot 32 cut into the top plate 14 may reside primarily in the fourth section while in the third section a hole 16 may be tapped into the top plate 14.

(22) In an embodiment of the present invention, a bottom plate 26 may have a center slot 27 cut into the body of the bottom plate 26. The center slot 27 may extend in length the majority of the body of the bottom plate 26 yet may leave room at one end for product identification and the application of a protective coating 28. The bottom plate 26 may be shorter in overall length than the top plate 14. The bottom plate 26 may be made of steel or other similar material.

(23) In an embodiment of the present invention, the top plate 14 and bottom plate 26 may be sandblasted, powder coated or painted before applying a protective coating 28 to the end of the bottom plate 26.

(24) In an embodiment of the present invention, when assembled, the bent top plate 14 may be connected to the bottom plate 26 by using fasteners to connect the two together. By way of example, the top plate 14 and bottom plate 26 may be connected together by inserting a carriage bolt 30 into the slot 27 cut into the bottom plate 26 and extending through the slot 32 of the top plate 14 in the fourth section. A flat washer 22 may be positioned against the top plate 14 and a wing nut 20 may be threaded onto the carriage bolt 30 to secure the top plate 14 and bottom plate 26 together. The wing nut 20 may be loosened from the carriage bolt 30 to allow lengthening or shortening of the bottom plate 26 to attain desired length. Upon reaching desired length, the wing nut 20 should be tightened firmly to the flat washer 22 and carriage bolt 30.

(25) In an embodiment of the present invention, components may be connected to form a clamping attachment that secures a rigid material to the invention. The clamping attachment may be comprised of a thumbscrew 18, lock nut 38, cupped washer 36, and a cotter key 34. The thumbscrew 18 may be inserted into the hole 16 drilled into the top plate 14 in its third section, the lock nut 38 may be threaded onto the thumbscrew 18, and the cupped washer 36 may be fit onto the thumbscrew 18 and rest against the lock nut 38. A hole 40 may be drilled into the end of the thumbscrew 18 into which the cotter key 34 may be inserted to hold the cupped washer 36 in place.

(26) It is to be understood that the form of the method and apparatus described herein is to be taken as preferred examples of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention.
