Abstract
The present invention relates to a simplified construction of the sawhead and carriage for a portable sawmill. This design allows for lower construction cost along with ease of operation.
Description
Specification It is well known that band mill main components are a bed, a sawhead and a carriage. In existing sawmills, the sawhead is a metal frame that support various brackets for the mechanical components and the blade guard.
My invention is a new design of sawhead and carriage for a portable sawmill, this design incorporate a unibody sawhead design simplifying the construction of the said sawmill.
Description of the drawings:
Fig. 1 represents an isometric view of a complete sawmill.
Fig. 2 represents an isometric view of the rear of the sawhead/carriage assembly.
Fig. 3 represents an isometric view of the front of the sawhead/carriage assembly.
Referring to Fig. 1; the carriage (1) rest on the bed tracks (12) and is free to roll on the said bed (12), a log would be installed longitunually on that bed (12) and be sawed. The sawhead (2) is supported by the carriage (1) and is adjusted up and down the carriage (1) to obtain the proper sawing height.
Referring to Fig. 2; the carriage (1) has built in sheet metal vertical tracks (4) that guide the sawhead main wheels (3) as the sawhead (2) travel up and down to adjust the sawing height. Side guide wheels (5) prevent the sawhead (2) from moving sideways in the carriage (1). Gas cylinders (6) can be installed as an option on each side of the carriage (1), either thru a direct connection or thru an indirect connection like cable or chains, to help raise the sawhead (2).
Referring to Fig. 3; the sawhead (2) frame is a metal sheet that form the back, top and bottom. A reinforcing member (8) is installed at the horizontal running from each end of the sawhead (2), this reinforcing member (8) in addition to reinforcing the sawhead (2) creates a certain thickness to the sawhead (2) that allows for mechanical components like the drive belt tension device (9), blade tension device (10) and blade guides (11) to be supported without further brackets or supports.

Claims
The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
-A sawmill sawhead frame that is composed of a sheet metal back wall reinforced with an horizontal member that allows for mechanical components to be mounted without additional brackets.
-A sawmill carriage with built in sheet metal vertical tracks that guides the sawhead wheels as the sawhead travel up and down.
-A sawmill sawhead constructed of sheet metal skin that forms the blade guard and reinforced to support the mechanical components of that sawhead.
-A sawmill drive belt tension device that the return to neutral is cushion by a hose also serving to supply coolant liquid to the blade.
-A sawmill blade tension device with the lever inside the blade guard cover.
-A sawmill sawhead frame that is composed of a sheet metal back wall reinforced with an horizontal member that allows for mechanical components to be mounted without additional brackets.
-A sawmill carriage with built in sheet metal vertical tracks that guides the sawhead wheels as the sawhead travel up and down.
-A sawmill sawhead constructed of sheet metal skin that forms the blade guard and reinforced to support the mechanical components of that sawhead.
-A sawmill drive belt tension device that the return to neutral is cushion by a hose also serving to supply coolant liquid to the blade.
-A sawmill blade tension device with the lever inside the blade guard cover.
