Definitions

  • This invention relates to exhausters, and has for an object to provide an improved device of this character in which the working parts are eiiciently protected from contact with the gases which are drawn through the machine.
  • Exhausters are commonly used to expel foul air, products of combustion, or other'.
  • Figure 1 is a longitudinal, vertical section through the center of the exhauster
  • Fig. 2 is an end elevation of the exhauster with the fan removed
  • Fig. 3 is a fragmentary top view.
  • the frame work of the exhauster shown in the drawings consists of four longitudinal angle irons 1 connected at 'one end by horizontal and vertical angle irons 2 and 3, and attheir other end by a frame 4 which constitutes the mouthpiece of thepipe or conduit 5 through which the gases to be exhausted are drawn.
  • the pipe 5 is shown in the form of an elbow rectangular in crosssection.
  • the mouthpiece 4 is shaped at its inner endto correspond with the cross-section of thepipe 5 and is circular at its outer end.
  • a tube 9 extends from an o ening 10,in the rear wall of the-pipeJ 5 to tige ring 8.
  • a fan 14 of the propeller type operating to move the gases in a general axial direction, and. the inner end of the shaft is coupled to the shaft of a motor 15 which is mounted upon a bracket 16 attached to the transverse angle iron 2 of the frame.
  • the bearing 11 is lubricated from an oil cup 17 located at one side of the motor 15.
  • An oil pipe leads from the oil cup 17 to the interior of the bearing casing 11. This pipe 18 lies within the tube 9.
  • the lower'end of the pipe 5 isv connected by a pipe or suitable conduit with the chamber or lreceptacle from which foul air, or other gas, is to be exhausted.
  • Another advantage of the embodiment of my invention which I have described is that it provides a compact structure in which the of these gases. It is thus possible to use a smaller pipe and smaller' fan than would be possible were the motor within the pipe 5. Furthermore the motor ⁇ is readily accessible.
  • the pipe 5 through which the gases are exhausted my be circular in crosssection or of other desired form.
  • This pipe need not form an elbow as is shown in the drawing, and it may, if desired, be provided with a plurality of gas intakes instead of the single intake shown at the bottom in thev drawings.
  • a steam engine, internal combustion engine, or other rotor may be substituted for the electrical motor shown, ory the fan shaft may be driven by means of a belt pulley or other power connection.
  • the protective envelop of fresh air intro-- quizted through the tube 9 to prot-ect the working parts from the gases exhausted may be made use of in an exhauster in which the motor is placed within the pipe 5 directly behind the fan.
  • the air drawn in through the pipe 9 serves to cool the m0- tor as well as the fan bearing, and to protect the motor from the injurious action of chemicals or dust or grit carried by the gases exhausted.
  • An exhauster comprising a Apipe through which the gases to be exhausted are drawn, a tube extending into said pipe, av
  • An exhauster comprising a pipe through which the gases to be exhausted are drawn, a fan in the mouth foi said pipemounted upon a shaft extending through the outer wall of said pipe, a motor without said pipe arrangedvto rotate said shaft, a tube eX*- tending into said pipe and surrounding said shaft, and a bearing for said shaft located ⁇ 5.
  • An exhauster comprising an elbow pipe through which the gases to be exhausted areY drawn, a shaft bearing within said pipe, a frame supporting said bearing and having an annular opening surrounding said bearing, a tube, extending from said annular opening through the rear wall of said elbow, a motor without said elbow, a shaft extending from said motor through said tube and mounted in said bearing, anda fan onsaid shaft adjacent to said bearing.
  • An exhauster comprlsing a pipe through which the gases tobe exhausted are drawn, a fan, a bearing for said fan within said pipe, a tube extending from said bearing ⁇ through the wall of said cant receptacle without said pipe, and a lubricant pipe extending through said tube from said receptacle to said bearing,
  • An exhauster comprising a pipe through which the gases. to be exhausted are drawn, a propeller fan for drawing the gases through said pipe, a bearing for said fan centrally located withinsaid pipe, and means for providing a protective envelop of constantly renewed air between said bearing and the gases exhausted through said pipe.
