SAWMILL BED ASSEMBLY
A sawmill, a sawmill kit, I and a method for securing one or more components to a sawmill comprises fastening the one or more components between two or more metal plates and securing the plates to the bed directly and further through a plurality of mounting brackets. The components may include one or more of a toe board, a log rest, and a log turner. The components may be hydraulically actuated, and the hydraulics or other actuation systems may be attached to the side of a metal plate or disposed between the metal plates. The method reduces material usage, provides ease of assembly, and saves manufacturing and shipping costs over the prior art.
1 . A sawmill comprising:
a bed having a first rail and a second rail positioned parallel to each other,
a carriage having horizontal movement along the bed,
a sawhead attached to the carriage,
a cross-bunk having a first end and a second end, the first end attached to the first rail and the second end attached to the second rail, the cross bunk comprising an assembly of laminated sheets comprising:
two or more rigid plates horizontally extending from the first end to the second end and
at least one bolt,
one or more components for the sawmill secured between the two or more horizontally extending rigid plates by the at least one bolt, wherein the at least one bolt also fasten the two or more horizontally extending rigid plates to each other.
2 . The sawmill of claim 1 , wherein the at least one bolt supports and stabilizes the horizontally extending rigid plates; and the one or more components are movable within the horizontally extending rigid plates.
3 . The sawmill of claim 1 , wherein the one or more components comprises one or more of:
a toe board assembly;
a log rest assembly; and
a log turner assembly.
4 . The sawmill of claim 2 , wherein the one or more components comprises one or more of:
a toe board assembly;
a log rest assembly; and
a log turner assembly.
5 . The sawmill of claim 1 , wherein the one or more components comprises a toe board assembly, the toe board assembly further comprising a toe board operated by a hydraulic assembly, the hydraulic assembly comprising a top end and a bottom end, the top end secured to a top fastener, the top fastener secured to each of the two or more rigid plates, and a bottom fastener, the bottom fastener secured to the toe board.
6 . The sawmill of claim 5 , wherein the toe board assembly further comprising a vertically extending slot through the toe board, and the top fastener is received through the slot to allow a vertically slideable relation between the toe board and the top fastener.
7 . The sawmill of claim 6 , wherein the slot and the top fastener are sized to prevent horizontal movement of the toe board.
8 . The sawmill of claim 5 wherein the two or more rigid plates are positioned to prevent horizontal movement of the toe board.
9 . The sawmill of claim 1 , wherein the one or more components comprises a log rest assembly, the log rest assembly comprising a log rest operated by the hydraulic assembly, the top end secured to a top of the log rest and the bottom end secured to each of the two or more rigid plates.
10 . The sawmill of claim 9 wherein the two or more rigid plates are positioned to prevent horizontal movement of the log rest.
11 . The sawmill of any of claim 1 , wherein the one or more components comprises a log turner assembly, the log turner assembly comprising a log turning chain, a chain bar and a motor, the motor secured to the two or more rigid plates, the motor providing structural integrity to the assembly of laminated sheets.
12 . The sawmill of claim 1 , wherein the horizontally extending rigid plates are fastened to the rails with rigid brackets.
13 . The sawmill of claim 1 , wherein the two or more horizontally extending rigid plates are made of steel.
14 . The sawmill of claim 1 , the at least one bolt further comprising a spacer attached to the at least one bolt, the spacer tightly fitting a space between the laminated sheets and providing structural integrity to the assembly of laminated sheets.
15 . The sawmill of claim 1 , the at least one bolt further comprising spacers attached to the component fasteners, the spacers sized to prevent horizontal movement of the one or more components.
16 . A method for securing the one or more components to a sawmill of claim 1 , comprising:
fastening the two or more horizontally extending rigid plates to the bed of the sawmill with the at least one bolt;
securing one or more components for the sawmill in between the two or more horizontally extending rigid plates with the at least one bolt, wherein:
the at least one bolt of the one or more components for the sawmill support and stabilize the two or more horizontally extending rigid plates; and
the one or more components for the sawmill are freely movable within the two or more horizontally extending rigid plates.
17 . The method of claim 16 wherein the securing also secures and supports the rigid plates.
18 . A kit of parts for constructing a sawmill of claim 1 comprising the bed, the carriage, the sawhead, the cross-bunk, the one or more components and the at least one bolt.
