Dual path kiln improvement
First Claim
1. A load mover for an elongated kiln structure having at least three chambers arranged serially from one end of the structure to the opposite end with said ends being open to allow the passage of said load mover and a load of lumber, said kiln structure having a floor and a pair of parallel rails mounted on said floor and extending along a path that extends from outside said structure through said chambers and through said ends of said structure,said load mover including a housing having a wall with which at least a portion of a load is engageable for transport sequentially through said chambers of the kiln structure, said housing having wheels that, in use, engage and ride on said rails,said kiln structure having a track extending parallel to said rails and through said kiln structure, said track being mounted on said floor,said load mover having mounted thereon a variable speed electric motor and gearing constructed for transferring the output of said motor to a transport gear which is rotatably mounted on said housing of said load mover and which engages said track so that rotation of said transport gear will effect movement of said load mover on said rails, andsaid wall having a substantially vertical portion to engage a load supported on a separate carriage which rides on said rails where said vertical portion is positioned to be moved against a load to enhance the stability of the load during transport along said rails.

Abstract
A dual path kiln is provided that includes a kiln having one or more chambers and at least two lumber charge paths adapted to convey lumber through the kiln in opposite directions by means of a track having two rails in which a pusher device pushes the lumber through the kiln and comprises a variable output electric motor to effect a high degree of accurate control of the movement speed of the pusher device and the lumber it'"'"'s pushing and wherein the pusher device includes a faceplate having two side walls extending from said faceplate to engage the side of the lumber in order to greatly enhance stability of the lumber while it is being transported and minimize the risk of spillage.
