Of these flanges, each inner flange begins where the outer flange terminates, while the middle flange 4 is considerably wider than either of its fellows. Seated on the uppermost flange 5 is an upwardly extending cylindrical member 6 having an open bottom adapted to enclose snugly the disc-like portion formed by that flange. The upper end of this ferrule 6 also carries a top closure 7 having a central perforation or aperture 8 therein.

  • the members 6, 7 i 9 are suitably united with the base 1.
  • the cylindrical member 9 acts as a art of a connecting means holding the memers 7 and 6 firmly to the base.
  • bottom 10 of the member 9 supports a countersunk member 10 and both 10 and 10 are provided with a central perforation 12 ada ted to permit the passage of a bolt 13,
  • the base 2 is provided with a central opening 15 communicating with the aperture 2, though of smaller diameter than the latter, a flange 16 thus being formed surrounding the bottom of the aperture 15.
  • a bottom plate 17 also rests against this flange 16 and the bolt 13 passes axially through this plate and is connected thereto by suitable means, such for example as a nut 18.
  • Improved heating means are also disposed within the member 6.
  • these means comprise a. plurality of coils of a suitable heating element, indicated at 19 and wound about the member 9 substantially throughout the length thereof.
  • a suitable heating element indicated at 19
  • the element 19 is in the form of a series of conductors covered with asbestos, since such an element is adapted to be applied when wet to the member 6 and when dry to stick thereto in such manner as to requireno other attaching means.
  • any suitable number of circuit connections of these coils 19 may be used which is found adapted to the particular conditions required.
  • two concentric series of coils 19 in series connection are rovided; and these are suitably insulating om the outer member 6 by suitable insulating material 21 disposed between the coils and the inside diameter of the member 6.
  • This insulating material may be of different char.- acter, but the same herein is in the form of tape.
  • these heating coils 19 are also connected to a usual conductor or cable 22 which is extended through a suitable lateral aperture 2 3 in the base 1, herein opening into the bottom of the aperture 15.
  • a separate receptacle is preferably placed in the member 9.
  • a receptacle 25 in the general form of a glass or other suitable test tube, is snugly fitted into the member 9.
  • the member10' is preferably made in the form of a seat ada ted to fit the bot: tom of this member 25. erein, for example, the'test tube25 having a rounded bottom. the upe'r surface of the member 10' is suitably diied or-hollowed out, as shown at 27, to
  • this member 10 is preferably formed of metal and thus adapted to conduct heat to the bottom of the testtube.
  • the test tube 25 also carries a nozzle member fitted in the top of the latter.
  • this member has an upstanding portion 29 adapted. to be and that it is also provided with a suitable oppositely disposed extension 30 which extends downward asubstantial distance into the member 25.
  • a spray bulb 31 it will be evident that the device may be held conveniently in one hand while the nozzle member is used as desired, while where a bulb is provided the other hand may be. used to operate the bulb.
  • the base 1 may be grasped in the palm of the hand when the device is used, it is preferred'to provide additional means for inserted in the nostril or mouth, as desired,
  • a covering 34 herein formed of asbestos or other suitable non-conductor of heat, encloses the member 6 and is held in position thereon by the flange 5 and by a suitable depending flange 35 or equivalent projections formed on the periphery of the member 7.
  • an outer cylindrical shellmember 36 is herein provided. This shell member 36 herein is suitably attached to the base, as by a screw 36', and extends upward from the flange 3 in spaced relation to the member 6 in such manner as to be insulated from and insulate the latter and provide a cool grasping means.
  • this member 36 is suitably bushed at 37 to receive the cable 22 and also provided with series of radially disposed apertures 39, 40 near the bottom and top thereof, respectively, in such manner as to permit air circulation and a still further cooling effect.
  • the upper end of the member 36 is curved inward, as shown at 41, in such manner as tooverlie the member 7 and confine the heat to a certain extent above the top thereof while preventing objectionable heating of the bulb 31 or ones hand or face.
  • a suitable aperture 42 is, of course, provided in this portion 41 to permit the insertion and removal of themember- 25' when;
  • the device may be very conveniently and safely handled, while danger from fire, should the same be overturned, is also minimized.
  • Fig. 3 is illustrated a modified construct1on which is generally similar to the 'construction shown in Figs. 1 and 2, with the exception that a flange 43, generally similar to the' fiange 5 but Wider than the latter, is provided, and that a second spacing tube 44 is provided seated on a flange 45, generally corresponding to the flange 4 and within the outer shell member 36, in such manner as, where necessary, further to reduce the temperature of the member 36.
  • the base 1 is elongated vertically and provided with a reduced gripping portion having an outwardly extending flange 51 at its top.
  • the base is made to provide a convenient grasping portion adapted to be held in the hand while the flange 51 prevents the users hand from slipping upward into contact with the heating means carried above the base.
  • an outer ferrule member 52 is used surrounding a suitably raised portion 53 on the base 1 and resting on the upper surface of the flange 51,and this member 52 is disposed at its upper end under the member 7.
  • the member 52 while the outermost member, is ordinarily not provided with apertures corresponding to the apertures 39 .pact vertically.
  • the provision of the base enables the device to stand upright when desired.
