E. MOLINA. APPARATUS FOR TREATING RUBBER. APPLICATION FILED AUG, 5, 1908. Patented Mar, 2, 1909. WITNESS .3 rims/r A7TOHNEYS smoke chamber. .ber the hollow axle does not pass out of contact with the pin 26 until after the end of the drum has passed into the end Opening of the In the use of my improved apparatus the closure 25. is removed and the drum support,- 1 by the .end flanges 11. ed with one end" thereof extending'out through the opening in the smoke chamber and the inner end supportedupon the end of the pin or pivot 26. The drum is thus suported at both ends so that it remains in a orizontal position, and the open end is I moved inward axially so that it is supported is then inserted to constitute a bearing for 'upt entirely upon the pivot 26, andthe closure 25 support one end of the the axle and hel built on the grate bars 16 drum. A fire is and by closing the damper 23 the smoke is compelled to ass u ward through the purifier and-into t e smo e chamber. The drum is continuously rotated and the li uid caused to flow over the inner surface of t e drum so as to be exposed to the action of the smoke and gaseous roducts of combustion in a very thin film. ter the material has been treated to the desired extent, the damper 23 may be opened and the smoke permitted to pass e pipe 21. I My improved apparatus is especially adapted for use inthe treatment of the juice or sap of the rubber tree, to coagulate or solidi the same as a first step in the formation 0 rubber. The smoke purifier prevents solid particles from passing into the 01;; 'nd'er but does not affect the gases other 40 t a n to slightly cool them. The purifier thus serves the additional purpose of preventing the smoke .chamber from becomin heated to a high temperature. The li ui under the action-of the smoke slightl so 'di-' fies or coagulat'es and at the end of t e process forms a solid lining within the drum. To remove the material from the drum, I preferably cut a slit along one side thereof from end to end, .and by folding in the material at one side of the cut or slit it may be readily withdrawn in a sheet from the open end of the drum. The material after being removed will appear substantially as shown in Fig. 4, and will be in the form of a hollow cylinder A having a wall of substantially uniform thickness and having a slit'B along one side. Althou h the apparatus above described] designed for use in the treat-' is especial ment of ru ber yetit is evident that itmay' be, employed for various'other purposes in which it. is desired to treat a substance with gaseous products of combustion while being continuously agitated. I Having thus described my invention, I claim as new Patent: '65v and desire to secureby Letters 1. In an apparatus of the character d'escribed, a casing having two communicating chambers, means for supporting the burning material within one of said chambers, means for supporting and a tween said chambers. I I 2. In an apparatus of the'character detating the material to be treatedin'the smo e chamber, and a mass of pebbles within the communication bescribed, a casing having an opening in one I end thereof, a pivot extending inwardly from the opposite side of said chamber, and a1 rotatable drum Within said chamber and having a,.hollow axle mounted upon said pin. and said drum being removable through said openin 3.' 11% an apparatus of the character described, a chamber having a circular opening in one end thereof, a closure therefor, a pm extending into said chamber from the sidethe smoke passing from said fire chamber to said smoke chamber, and means for supporting the material to be treated smoke chamber. 5. An apparatus for treating rubber, including a smoke chamber, a rotatable drum within said within said chamber and having at each end thereof -'an inwardlydirected flange, a' fire chamber, and means for purifyingand cooling the smoke passing from said fire chamber to said smoke chamber. In testimony whereof have signed my name tothis specification in the presence of two subscribing witnesses. ENRIQUE. MOLINA. Witnesses: CLAIR. W. FAIRBANK, EVERARD B. MARSHALL.
