Abstract
A dual blade band saw cutting machine which allows two individuals to work on two different objects at two separate work stations within the same machine. Through the utilization of a single variable speed motor and two overlapping triangular rotational patterns, two safe and independent work stations with large working areas, each having its own cutting band, are provided. Additional features of the cutting machine include assemblies for adjusting the tension of the cutting bands, an assembly for varying the speed of the motor, and a display for informing the individuals operating the cutting machine of the rotational speed of the cutting bands in blade feet per minute.
Claims12
A cutting machine comprising:
- a housing supporting a table having an upwardly facing horizontal working surface;
- a power source supported and located within said housing;
- a plurality of work stations, each of said work stations comprising a plurality of guide wheels rotatably supporting a flexible, continuous cutting band, said plurality of guide wheels comprising, for each of said cutting bands, a drive wheel, an adjustment wheel, and an idler wheel, thus describing a triangular rotation pattern, at least one of said drive wheel, said adjustment wheel, and said idler wheel being located in said housing above said working surface and at least one other of said drive wheel, said adjustment wheel, and said idler wheel being located in said housing below said working surface, each of said work stations being configured such that a respective cutting band projects from said housing above said table working surface and is received into said table and is exposed to a user, thereby to enable work to be manipulated therearound and thus to be cut thereby, whereby a number of independent cutting operations corresponding to the number of work stations is enabled;
- said power source is adjustably supported within said housing by a plurality of adjustment bolts, and includes a variable speed motor and a plurality of drive belts powering said drive wheels, manual positioning control means mounted on said housing and mechanically connected to said power source by linkage including a shaft for adjusting said motor, said shaft employing a universal joint therealong so that all connections of said linkage reaming operable should said power source be adjusted when tensioning the drive belts used to transfer rotational power from said motor to said drive wheel of said triangular rotation patterns.
