## Background
BACKGROUND OF THE INVENTION
Various types of wood cutting machines are in use and are known in the prior art. However, what is needed is a wood cutting machine that is adaptable and easy to use, but at the same time, has characteristics that have not yet been utilized or conceived as shown in the present invention. The present invention provides the strength and utility of a large wood cutting machine for individual or light business use, while at the same time, provides stability to a board being cut by holding the board in place without an individual having to personally hold the board. This characteristic provides extra safety measures combined with the ability to make clean and straight cuts.
FIELD OF THE INVENTION
The present invention relates to a wood cutting machine, and more particularly, to a wood cutting machine that provides features and characteristics above and beyond existing wood cutting machines that are presently available today. Although a wide variety of wood cutting machines exist, none combine ease of use with the safety of the present invention and the ability to effectively and quickly cut wood. The present invention is simple enough to be used for personal or business use but versatile enough that it can be used to cut wood in a variety of different lengths, shapes, and configurations.
SUMMARY OF THE INVENTION
The general purpose of the present wood cutting machine, described subsequently in greater detail, is to provide a wood cutting machine which has many novel features that results in a wood cutting machine which is not anticipated, rendered obvious, suggested, or even implied by prior art, either alone or in combination thereof.
The present invention disclosed herein is a wood cutting machine that is fabricated from a central track that is mounted on a quartet of end legs and a pair of center legs that are height-adjustable. A number of cross supports are in operational communication with the central track. A frame is mounted on a pair of tracks that are in operational communication with the central track, with the frame including a pair of saw blades mounted on a blade shaft that is axially attached to the frame via a pair of mounts. A motor housing is in operational communication with the frame and includes an internal motor, which is in operational communication with the blade shaft via a pair of pulleys and an attached belt. A pair of rollers in operational communication with the frame help push down and stabilize any piece of wood configured to be placed on the central track, which can then be cut by moving the frame forward over the piece of wood. The blades will rotate and cut the wood as the frame is moved over the piece of wood.
Thus has been broadly outlined the more important features of the present wood cutting machine so that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.

DETAILED DESCRIPTION OF THE DRAWINGS
With reference now to the drawings, and in particular FIGS. 1 through 7 thereof, an example of the wood cutting machine employing the principles and concepts of the present invention and generally designated by the reference number 2 will be described.
Referring to FIGS. 1 through 7, a preferred embodiment of the present invention is disclosed. The wood cutting machine 2 disclosed herein includes a central track 4 having a first end 6 and a second end 8. The first end 6 of the central track 4 is attached to legs 10 and 12 and the second end 8 is attached to legs 14 and 16.
The central track 4 includes a left lower support 7 and a right lower support 9 attached lengthwise along the central track 4. The central track 4 has a plurality of cross supports 18 that run perpendicular to the length dimension of the central track 4 that provide extra support. Each of the cross supports 18 is attached atop the left lower support 7 and right lower support 9.
The wood cutting machine 2 also includes a pair of individually height adjustable center legs 20 and 22. Each of the center legs 20 and 22 is designed to be placed approximately halfway between the first end 6 and the second end 8 of the central track 4.
The central track 4 further includes a pair of tracks comprising a left track 26 and a right track 28. The left track 26 and the right track 28 are parallel to each other and are attached to the full length of the central track 4. Each of the left track 26 and the right track 28 is fixedly attached to the left lower support 7 and right lower support 9, respectively, by a separate bracket 24. The left track 26 and right track 28 are attached atop the cross supports 18 as well. A stop plate 29 is attached to each end of left track 26 and right track 28.
A blade mounting unit 30 is mounted atop the left track 26 and right track 28 by a plurality of runners 32. The blade mounting unit 30 includes a rectangular frame 36 that includes mounts 38 and 40, with blade shaft 42 being axially inserted into mounts 38 and 40. A pair of saw blades 44 and 46 are removably attached to the blade shaft 42 and are temporarily locked in place by the use of one or more lock collars 48, which are configured to be placed on each side of each saw blade 44, 46 to temporarily affix the respective saw blade in the desired spot on the blade shaft 42.
Motor housing 50 is also in operational communication with the frame 36, with motor housing 50 including an internal motor 52. Motor 52 is powered by a power cord 54 that is in operational communication with an external power source 56. Motor 52 is in operational communication with a first pulley 58 that is disposed outside the motor housing 50. A second pulley 60 is in operational communication with the blade shaft 42. A belt 62 connects the first pulley 58 to the second pulley 60. When the motor 52 is in operation, first pulley 58 and belt 62 causes second pulley 60 and blade shaft 42 to rotate as well.
A belt cover 64 is usually configured to be placed over the pulleys 58, 60 and the belt 62 when the wood cutting machine 2 is in use to minimize sawdust formation.
A pair of rollers 65, 66 are in operational communication with the frame 36 via an attached roller cam 68, with each roller cam 68 being inserted into a roller mount device 69. Two separate roller mount devices 69 are in operational communication with the rectangular frame 36 and each roller mount device 69 merely keeps a connection between a roller cam 68 and the rectangular frame 36, while the actual height of each roller 65, 66 in relation to the frame 36 or other objects of the present invention are determined by what each roller 65, 66 is resting upon.
In use, a board 70 to be laterally cut is placed on the central track 4 and a plurality of cross supports 18. Then, the roller 65 is adjusted for placement atop the board 70 and the blade mounting unit 30 is moved forward by hand, slowly along the length of the board 70. The saw blades 44, 46 will slowly cut lengthwise along the length of the board 70, while at the same time, rollers 65 and 66 will help to secure and affix the board 70 in a particular position to prevent movement while cutting the board 70. Rollers 65 and 66 operate primarily by the use of gravity and exert a slight downward pressure on the board 70 while the board 70 is being cut.
In use, a safety shield 80 is preferably configured to be placed over the frame 36 while the wood cutting machine 2 is in use. A ventilation hose 82 is in operational communication with the safety shield 80 via a hose connection 84. The ventilation hose 82 preferably removes air and wood debris on a continuous basis while the wood cutting machine 2 is in use.
