Appl. No.:

5/747553

Inventors:

Roy R. Pryor - Woodville TX
Harold A. Pryor - Woodville TX

International Classification:

B65G 5908

US Classification:

214 6C

Abstract:

An improved fully mechanized sawmill is provided which is composed of structurally independent modules which are removably mounted on a platform composed of a plurality of side-by-side longerons supported horizontally on files of spaced-apart vertical piers and columns. The longerons provide horizontal stress support for the platform along the files of piers and columns perpendicularly to the cutting axis of the sawmill, and the modules mounted thereon provide horizontal stress support for the platform along the ranks of the piers and columns parallel to the cutting axis. In addition, improved mechanisms and techniques are provided for handling and selecting the sawlogs to be cut, for selecting and distributing the pieces cut therefrom according to shape and utility, and for stacking and handling the distributed pieces at preselected locations according to shape and utility. In particular, the stacker assembly comprises a plurality of lifting arms fixedly positioned at one end on a rotatable cross-bar. Rotation of the cross-bar elevates the lifting arms.

Abstract:

An improved trimmer section is provided for use in a sawmill, together with method and means for automatically selecting timbers and the like to be trimmed, and for automatically routing trimmed timbers to a preselected one of a plurality of different storage and loading points in the sawmill. In particular, the operator is required to select which of several stations is to receive each timber after it has been cut to a designated length. Thereupon, the timber is automatically transferred through several stages of mechanical manipulation to the designated station while, simultaneously therewith, another un-trimmed timber is promptly conducted to the trimming saws. Actuation of the entire operation is effected by merely selecting the station to receive the trimmed timber, since the cycle will repeat as long as there are timbers to be trimmed.

Abstract:

This invention is directed to an improved stop and loader assembly for use in a sawmill and the like, and more particularly includes an improved combination slapper bar and log turner. The combination slapper bar and log turner preferably includes a rectangular hollow slapper bar section which contains a movable member having a plurality of teeth pivotally attached thereto. A fluid-actuated piston assembly is provided for drawing the movable member and teeth longitudinally in and out of the slapper bar. A slot is further provided in the upper end of the slapper bar and adjacent any sawlog reposing on the carriage next to the slapper bar, whereby the teeth fall out of the slapper bar in an extended position to engage the log when the movable member is thrust upward in the slapper bar, and whereby the teeth fold into the slapper bar whenever the movable member is drawn downward therein.
