Abstract: A sewing machine with a dust removing device prevents trouble such as faulty sewing caused when dust including waste thread and waste cloth is collected under a throat plate, in performing, for example, interlock stitch sewing by an overlock sewing machine. Specifically, an upward air introducing path is provided, through which the cooling airflow generated by a cooling fan actuated during sewing operation is fed to an air introducing path for oil cooling underneath a lubricating oil storage part, and, through which the cooling airflow passing through the air introducing path for oil cooling is blown up from the underside of a frame to a needle location of the throat plate, in order to blow up the dust. An opening of one end of a suction pipe for collecting dust attached to the frame is disposed sidewise above the throat plate.

Abstract: The actuating lever of this invention is intended for use with an air valve having a normally extending valve stem. The actuating lever has utility in many fields. One illustrated embodiment is described in association with an air valve in the waste removal system of a sewing machine, wherein it is desired that the air valve be activated before the sewing machine is activated by depression of a treadle. It is normally desired to initiate the flow of compressed air to create a suction for the removal of waste generated by operation of the sewing machine before the sewing machine is started. The configuration of the actuating lever provides a mechanical advantage that, in the illustrated embodiment, enables the valve stem of the air valve to be depressed with less pressure on the treadle than was required in the prior art, and with less pressure than is required to start the motor of the sewing machine.

The chute consists of: an elongated tube, having an enlarged transversely opening mouth at one end, and a smaller axially opening outlet port at the opposite end.

Abstract: A tape waste collector assembly is suited for use with a belt loop sewing machine having a tape cutter for cutting a length of tape placed on a tape receiving plate into pieces of a predetermined length so that each of the pieces of tape may be sewn on a garment to form a belt loop. The tape waste collector assembly includes an air source, one or more air pipes pneumatically connected to the air source for blowing compressed air supplied from the air source towards the length of tape placed on the tape receiving plate, and a plurality of tape waste collecting elements such as, for example, a hose, a waste box and the like for collecting tape wastes produced when the length of tape is cut by the tape cutter. A controller controls a plurality of solenoid valves to operate the air pipes and the plurality of tape waste collecting elements so that the tape wastes blown off by the air pipes are appropriately collected by the plurality of tape waste collecting elements.

Abstract: A lint barrier for a sewing machine which excludes lint from entering the interior of the sewing machine having a machine housing enclosing the internal workings of the machine. The sewing machine also includes an oil cooler adapted to cool oil circulating through the sewing machine, the cooler including a plenum, a radiator and an air source for moving air through the radiator. A conduit connects the air source to the interior of the sewing machine, whereby air is conducted through the conduit and into the interior of the sewing machine to maintain a positive pressure within the sewing machine interior, thereby preventing the entry of lint into the sewing machine interior.
