Abstract
A cooling and waste collection system for a sewing machine which includes a fan connected to a main shaft of the sewing machine, and an air passage having a suction passage and a cooling passage, where the suction passage feeds in air from the outside atmosphere to an air blowing chamber. The cooling passage feeds air from the air blowing chamber to an oil pan of the sewing machine. The suction passage has one end connected to the air blowing chamber and another end opening at the work area of the sewing machine. The cooling system further comprises a waste collection system positioned in the air passage for accumulating waste materials generated when sewing.
Claims12
A cooling system for a sewing machine comprising:
- a fan rotatably driven by a main shaft of the sewing machine;
- an air blowing chamber partially enclosing said fan;
- an air passage having a suction passage for feeding air from the outside atmosphere to said air blowing chamber and a cooling passage for feeding air from said air blowing chamber to an oil pan of the sewing machine, said suction passage having one end connected to said air blowing chamber and another end opening at the sewing area of the sewing machine, and said cooling passage having one end connected to said air blowing chamber and another end connected to said oil pan;
- an air intake port mounted within said cooling passage;
- and
- pressure decreasing means mounted within the cooling passage for lowering the air pressure at said air intake port and to draw air through said air intake port.
A cooling and waste collection system for a sewing machine, comprising:
- a fan rotatably drive by a main shaft of the sewing machine;
- an air blowing chamber partially enclosing said fan;
- an air passage having a suction passage for feeding air from the outside atmosphere to said air blowing chamber and a cooling passage for feeding air from said air blowing chamber to an oil pan of the sewing machine, said suction passage having one end connected to said air blowing chamber and another end opening at the sewing area of the sewing machine, and said cooling passage having one end connected to said air blowing chamber and another end connected to said oil pan;
- waste collection means mounted within said air passage;
- and
- a suction power means positioned between the air blowing chamber and the suction passage for generating suction forces by the rotation of the fan.
