Abstract
A kit for constructing a sawhead comprises a pair of plates adapted to be stacked upon and secured to one another by bolts to form a plate stack. The kit further comprises a pair of elongate guide receivers. Each guide receiver has a longitudinal axis and an interior wall which defines a bore extending through the each guide receiver and through which bore the longitudinal axis extends. The interior wall has a cross-section which is substantially constant along the length of each guide receiver. The guide receivers are adapted to be mounted to the plate stack by bolts at respective operative positions whereat the longitudinal axes are oriented parallel to one another and whereat the guide receivers are spaced from one another in a direction transverse to the axes.
Claims19
An improved sawmill having:
- a bed defining a first translation axis:
- and
- a carriage, the carriage being mounted to the bed for movement along the first translation axis;
- and defining a second translation axis and a lateral axis, the second translation axis being orientated transverse to the first translation axis and the lateral axis being orientated transverse to each of the first translation axis and the second translation axis,
- wherein the improvement comprises:
- two or more elongate guide members secured to the carriage for movement therewith along the first translation axis, the guide members each being orientated parallel to the second translation axis and being spaced apart from one another in the direction of the lateral axis;
- and
- a sawhead, the sawhead comprising:
- two or more guide receivers, each guide receiver being mounted to a respective one of the pair of guide members;
- two or more plates extending parallel to said first translational axis, said plates stacked upon and secured to one another to form a plate stack, the plate stack being secured to each of the two or more guide receivers;
- and
- one or more reinforcing members sandwiched between the plates in the plate stack and secured to the plates.
A constructed sawhead for use as part of a constructed sawmill, said constructed sawmill having:
- a bed defining a first translation axis;
- a carriage, the carriage being mounted to the bed for movement along the first translation axis;
- and defining a second translation axis and a lateral axis, the second translation axis being orientated transverse to the first translation axis and the lateral axis being orientated transverse to each of the first translation axis and the second translation axis;
- and
- two or more elongate guide members secured to the carriage for movement therewith along the first translation axis, the guide members each being orientated parallel to the second translation axis and being spaced apart from one another in the direction of the lateral axis,
- constructed sawhead comprising:
- two or more plates adapted to be stacked upon and secured to one another by bolts to form a plate stack;
- and
- two or more elongate guide receivers, each guide receiver having a longitudinal axis and an interior wall which defines a bore extending through said each guide receiver and through which said longitudinal axis extends, the interior wall having a cross-section which is substantially constant along the length of said each guide receiver, two or more guide receivers being adapted to be mounted to the plate stack by bolts at respective operative positions whereat the longitudinal axes are oriented parallel to one another and whereas the guide receivers are spaced from one another in a direction transverse to said axes.
A kit for constructing a sawhead for use as part of a constructed sawmill, said constructed sawmill having:
- a bed defining a first translation axis;
- a carriage, the carriage being mounted to the bed for movement along the first translation axis;
- and defining a second translation axis and a lateral axis, the second translation axis being orientated transverse to the first translation axis and the lateral axis being orientated transverse to each of the first translation axis and the second translation axis;
- and
- two or more elongate guide members secured to the carriage for movement therewith along the first translation axis, the guide members each being orientated parallel to the second translation axis and being spaced apart from one another in the direction of the lateral axis,
- said kit comprising:
- two or more guide receivers, each guide receiver, upon construction into an operable sawmill, being mounted to a respective one of the pair of guide members;
- two or more plates, upon construction into an operable sawmill, extending parallel to said first translational axis, said plates, upon construction into an operable sawmill, stacked upon and secured to one another to form a plate stack, the plate stack, upon construction into an operable sawmill, being secured to each of the pair of guide receivers;
- and
- one or more reinforcing members sandwiched between the two or more plates in the plate stack and secured to the plates upon construction of the sawhead.
