AMALGAIVIATOR.
SPECIFICATIOH forming part of Letters Patent N 0. 752,246, dated February 16, 1904.
Application filed October 7, I902. Renewed uly 22, 1903. Serial No. 166.634. (No model.)
To all whmn it may concern:
Be it known that I, PETER J. NELSON, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Amalgamators, of which the following is a specifitory tank preferably employed therewith, and
Fig. 2 is a longitudinal sectional'view of the amalgamator.
In the embodiment of the invention as illustrated in the drawing Fig. 1 two tanks are employed-a main tank A and a supplemental tank B. These tanks may both be formed of the same casting or may be cast separately, as in the present instance, this depending largely upon the size of the machine.
The two tanks A and B, which are substantially similar in construction, have their adjacent walls a, and b abutting and in the present instance rigidly bolted together, as shown, the said wall a of the main tank being provided at its upper edge with a flange a, overhanging the other wall 6. Each tank is provided at both ends with vertically-extending abutments c and c, and vertical shoulders (Z d and partitions e e are placed in vertical position against said abutments and are held thereagainst solely by wedges ff, interposed between the partitions and the said shoulders, as indicated in Fig. 1. Hence the partitions may readily be withdrawn and replaced whenever desired. Each of the partitions is provided in its lower edge with a plurality of recesses g. The partition of the main tank A forms a feed-passage h with the adjacent wall of said tank, said passage leading from a hopper z'of any suitable character, and the partition of the supplemental tank B also forms a passage h with the adjacent wall Z1, which latter passage receives the overflow from the and on each shaft is a plurality of blades or beaters 5, arranged in such position on their respective shafts that they will sweep through corresponding recesses g in the partitions, whereby'to carry down the ore-bearing slime from thepassages 7L and it into and through bodies of mercury at the bottom of the tanks, the level of said mercury being indicated in Fig. l by the dotted linem. That portion of each tank below said line forms a mercurychamber. Each blade is preferably concave transversely on its advancing face, as'illustrated.
The bottom of each tank slopes forwardly, preferably from the level of the mercury to the front wall, where each tank is provided with a bottom discharge, and said bottoms also slope from the ends of the tank to the middle, as indicated in Fig. 2. As also indicated in said figure, the bottom discharge includes a pipe it, provided with two independent cocks or valves a M, the first valve being close to the discharge-opening and the second placed at any desired distance from the first valve. The length of pipe between the two valves forms a receptacle for the amalgamated material, which can be drawn off without disturbing the main body of mercury by closing the valve a near the bottom of the tank and opening the second valve n thereby emptying the pipe. As soon as the pipe has been emptied the valve n is closed and the valve it opened. The tanks are further provided at a point above the mercury-level with discharge-pipes 0 0, by which the water, mud, and the slime may be drawn off without disturbing the body of mercury, thereby exposing the shafts and revoluble heaters, so as to make repairs inside the tanks quickly, and the supplemental tank is, moreover, provided with anoverflowout- Fig. 1, below and in a vertical plane between said two shafts 7c and It, and said driving-shaft p is also mounted at its ends for the sake of rigidity in standards q, independent of the machine standards. One of said independent standards is illustrated in Fig. 2. The three shafts 70, la, and p are geared together by spurwheels 70 70 and 19 as shown in Fig. 2 and in dotted lines in Fig. 1.
In connection with the two amalgamatingtanks I preferably employ a preparatory tank C, supported in-any suitable manner with its discharge '1" above the hopper 2' and provided with a number of mixing-blades s. The purpose of this preparatory tank is to mix the slime, sand, or other ore-bearing material before it reaches the amalgamator.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. An amalgamator, comprising a tank provided with a mercury-chamber; a partition secured in said tank and forming therein a feed-passage for the slime and the like to the mercury-chamber, said partition being provided in its lower edge with recesses; and revoluble beaters arranged to sweep through said recesses into both the feed-passage and the mercury-chamber, as and for the purpose set forth.
2. An amalgamator, comprising a tank provided with a mercury-chamber; a vertical partition in said tank and forming therein a feedpassage for the slime and the like to the mercury-chamber, said partition being provided in its lower edge with recesses; and revoluble beaters arranged to sweep through said recesses into' both the feed-passage and the mercury-chamber, and concave transversely on their advancing faces, as and for the purpose set forth.
3. An amalgamating-Inachine, comprising two tanks arranged with side walls abutting whereby to form an overflow from one tank to the other; and the bottom of each tank sloping from the rear wall to the front wall, where it is provided with a discharge; a partition in each tank and said partitions provided in their lower edges with recesses; shafts extending through said tanks; beaters concave transversely on their advance faces and mounted ,on said shafts and arranged to sweep through said recesses; and a driving-shaft arranged to rotate said other shafts, as set forth.
In testimony whereof I afiix my signature in the presence of two witnesses.
