  • Fig. 3 a rear elevation of the machine, partly broken away, and with certain portions in section;
  • Fig. 4 a vertical axial section of the machine
  • the main object of the present invention is to so construct the apparatus that,the heated air is introduced directly into the drum where it rst contacts the goods to be treated, and then passes outwardly through the perforate wall of the drum to an exhaust passage or oiftake.
  • the arrangement is such that'the heated air which is introduced into the central portion of the drum or about and around the axis thereof, flrstcontacts the goods in the drum and is then drawn outwardly through the perforate drum wall to an exhaust fan through which the vapor-laden air is discharged.
  • a further object of the invention is to provide a structure wherein means is present to cause the air to follow the path above outlined, without undue impedance. 'I'he parts are, however, so proportioned and arranged as to evenly distribute the ⁇ flow of air outwardly of the apparatus'. p

  • Head 43 is imperforate and the same is true of the head 44 except for a large central opening formed therein dened by an inwardly extending fiange 45 which surrounds the inner portion or end of the member 28 in spaced relation thereto.
  • the inwardly extending flange 45 is curved, and together with the adjacent portion of the member 26, forms an annular orifice denoted by 45.
  • This annular space is, in effect, a nozzle through which the indrawn air is normally caused to pass, and by reason of the curvature of the member 45, friction or resistance is at the minimum.
  • a series of lifter elements which may be formed in various ways.
  • they are produced from sheet metal bent to form, the sheetsy being folded upon themselves into a general V-shape in cross-section, so as to produce the lifter whichjs designated generally by 46.

  • stub shaft 52 having strengthening ribs' 49 .radiating from a centrally disposed hub-like element i, the outer end of which is reduced, forming a stub shaft 52.
  • Said stub shaft ex ⁇ tends into a housing or casting 53 in which it finds its support, suitable roller bearings or the like (not shown) being provided at the outer end of the shaft and at the inner portion thereof adjacent the hub.
  • Stub shaft 52 has secured to it (see more particularly Fig. 3), a sprocket 54 about which passes a sprocket chain 55, which chain also passes about a second sprocket 5B mounted upon a counter-shaft 51 driven Iby an electric motor 58, or other suitable source of power.

  • this packing is U-shaped in form and when produced from heavy felt or the like will, by reason of its U-shape, spring outwardly and closely contact the adjacent wall of the casing, forming a continuous seal between the rotatable drum and the casing. Thus, passage of air around the end of the drum at this point is precluded. Any form -of seal and the securement thereof at this point be drawn into the rotating dnmi and directly into contact with the goods which are being cascaded therein, prior to its outward passage through the perforate wall of the cylinder.
  • a chamber as 59 will be formed or mounted upon the ⁇ upper end of the cylindrical shell or casing I6, and a suitable heating element is mounted in the intake end of said casing, which end is open to the atmosphere.

  • Fig. 5 the apparatus is shown vin the dia--v grammatic or outline form, this with a view of clearly indicating the passage of the air through the apparatus.
  • the incoming air passes into the upper portion of the structure where it is heated, thence is drawn downwardly through the openings 29 and through the nozzle or space 45, and is thus projected centrally into the drum.
  • the air may pass through the openings or apertures 28 in the sleeve-like member 26 and into the drum in the event that the cascading articles being treated in the drum should tend to close off portions of theY main air inlet. to wit, the nozzle 45".
  • the air is precluded from passing varound the end of the drum or cylinder and exteriorly of the same by the packing 50, which seals off the space between the outerV wall of the drum and the casing; thus, short-circuiting of the air is precluded and it must. all pass axially and inwardly into the drum.
  • the air is thus brought into direct contact with the goods which are being cascaded within the drum, contactingy the same prior to any contact with the perforate wall of the drum, and the heat units are given upnilrst to the goods and not'primarily to the drum.
