AMALGAMATOR.

SPECIFICATION forming part of Letters Patent No. 790.000, dated May 16, 1905.

I Application filed March 28, 1904. Serial No. 200,360. l

To @ZZ whom t may concern:

Be it known that I, JOSEPH J PEAooox, a

. citizen of the United States, residing at Chicago, in the county of Cook and State of Illigamators of the general construction shown in patent to Hoyt, No. 636,300, dated November 12, 1901.

My primary o bject is to provide a practical construction for amalgamators of the general character referred-to, having regard for the practical working conditions under which the amalgamator must be employed.

My invention is illustrated in the accompanying drawings', in which- Figure 1 represents a broken longitudinal sectional view of an amalgamator embodying my improvements, the section being taken as indicated at line 1 of Fig. 2 Fig. 2, a plan view of the same; Fig. 3, a broken section similar to Fig. 1, but on an enlarged scale;

Fig. 4, a transverse section taken as indicated at line 4 of Fig. 3; Fig. 5, a broken plan section taken as indicated at line 5 of Fig. 3; Fig, 6, a transverse section taken as indicated at line 6 lof Fig. 3; Fig. 7, a broken perspective view showing the manner of joinmator, andv Fig. S a perspective view of a removable amalgam-pan and a fragment of acopper lining employed for forming lapjoints as shown in Fig. 3.

In the preferred construction, A represents any suitable frame provided with a top havmg a desired inclination; B, an inclinedsluice supported on said frame and composed -of similar alternate sections B B2, suitably joined together; B3, a series of amalgampans virtually forming linings for the sluicesections B2; B4, lining-sections employed for makingl lap-joints; C, a series of pairs ofv standards adjustablysup orted on the sluicesections B2; C, verticaliD -adjustable hangers or bearings connected with the standards C` and havin 4their lower ends extending within `the s luiceto'near the bottom thereof;

C2, rollers or cylinders journaled in the lower .ends of said hangers and dipping into 'concavities with which the removable amalgampans are'provi'ded; C3, a series of transverse shafts j ournaled in the upper ends of the standards C, andC1 a seriesv of chains or other flexible connections connecting the shafts-in pairs, as shown.

I have shown the frame A composed ofv suitably-supported side members a, connected by suitably-spaced cross members a. It will be understood, however, that any suitable frame may be employed.

In the preferred construction of the sluice B the sections B comprise open troughs of rectangular cross-section and each having a 'plane bottom and sides and having external end ilanges Z, as shown, and the sections B2 are somewhat similar in general formation and are e uipped externally with end anges b and top(llanges b2. The sections B2 are preferably shorter than the sections B and each of the sections B2 is provided centrally at-its bottom with a hollow enlargement b3, extending transversely of the sluice, and each` of the sections B2 is recessed internally at the upper portions of its sides, as shown at t4. The'end flanges of the adjacent ends of adjacent sectionsy abut against each other and are connected by bolts b5.

section than are the lower ends of the sluicesections B, so that when the amalgam-pans B3 are inserted their internal surfaces are flush with the internal surfaces of the lower B4 comprise rectangular copper sheets having their lateral margins bent upwardly vto form sides. In assembling the parts the en- The sluice-sections 'B2 are of somewhat greater Internal crosslar ements b3 of the sections B2 receive the wel s b of the mercury-pans and the recesses b4 receive the handles 67. Also the lateral recesses bs of the mercury-pans receive the upperend portions of the sides of the liningsections B4, and each lining-section overlaps two joints of the sluice and terminates at its lower end adjacent to the upper margin of the well of the amalgam-pan at its lower end. The sides of the sluice-sections B are somewhat lower than the sides of the sluice-sections B2 and at their upper edges receive retaining-clips b, which serve both to aid in retaining the lining-sections in place and to present smooth surfaces at the upper edges of the sides of the sections B. On the under surfaces of the amal am-pans B3 and at the lower sides of the wel s b are spacing-lugs b1", which bear against the inner surfaces of the hollow enlargements b3 and insure the proper location of the amalgam-pans in the sluice.

-The standards C have sufficiently wide bases to rest firmly on the flanges b2 of the sluice-sections B2 and upon the upper edges of the amalgam-pans B3, and said standards are rmly adjustably secured to the flanges b2 bymeans of bolts c, which pass through perfo'rations of greater diameter than themselves in the standard-bases, as shown in Fig. 5. The inner surfaces of the standards C are substantially flush with the inner surfaces of the amalgam-pans, as shown in Fig. 4. The hangers C are provided at their upper ends with vertical slots, through which pass bolts c', by means of which the hangers are adj ustably secured to the standards. Each cylinder C2 comprises a hollow sheet-copper cylinder having inserted cast-metal ends c2, backed internally by Babbitt metal c3 and provided externally with trunnions or ournals. One ofthe Babbitt fillings c3 is backed by a disk c4, and the adjacent cylinder end is perforated to permit the Babbitt metal to be poured in. Each shaft C3 is connected by a belt c5 with the corresponding cylinder lying below it. As will be understood from Fig. 4, the cylinders are so journaled in the hangers that they will be restrained from rising under the buoyant action of the mercury, which is of high specific gravity.

By preference the mercury-wells are graduated in size from the upper end of the machine to the lower end thereof, the upper well being the largest. The purpose of thisnarrangement is to permit the use of successively less quantities of mercury in the wells from the upper end of the machine to the lower end in order that the live quicksilver may be used up at about the same time at all the wells, it being a fact that the wells collect the preclous metals in graduated quantities from the uper end of the machine to the lower end thereof, the largest quantitybeing collected at the upper end of the machine. y

The hangers C are preferably of wood fiber,

and the inner surfaces of the amalgam-pans are coated with aluminium-pain t, as are also the outer surfaces of the cylinder ends. lt is the purpose of the construction to employ as little iron as possible which shall come in contact with the mercury, and wherever iron does come in contact with the mercury the aluminium-paint will siiflice as a preservative.

From the foregoing detailed description the manner of use of the machine will be readily understood. Power is applied to the machine in any suitable manner, as by means of the hand-Wheel shown in Fig. 2, and sand and water are passed through the sluice in the usual way. During the operation the cylinders are revolved in the mercury-wells, thereby keeping the cylinders coated with. a thin covering of mercury, which serves to collect the particles of gold as they pass over or under the cylinders, according to the direction of rotation of the cylinders. To overcome any tendency to clog the wells with particles of gravel or sand and also to enable the maximum amount of material to be passed through the machine, it usually is desirable to rotate the cylinders so that their upper portions will move with the current, as indicated by the arrows. When it is found that as much amalgam has been formed as is practicable, the lining-sections B" and the amalgam-pans B3 are removed from the machine, which action is permitted by removing the standards C and the cylinders depending therefrom. lf desired, the same result maybe accomplished by loosening the standard-bolts and shifting the standards and then removing the hangers, with the cylinders supported thereby. Either course enables the cylinders to be removed from their bearings and thoroughly cleansed or replaced by substitute cylinders, and the lining-seetions and amalgamepans B3 may also be replaced, so that the operation of the machine need not be delayed while the amalgam is being collected.

It is noteworthy that in my improved construction provision is made for supporting and rotating the amalgam-cylinders without perforating the walls at the ends of the wells to provide bearings for the cylinders, so that there is no opportunity for the escape of mercury or ama gam, with consequent loss of material and injury to the machine. lt is also noteworthy that all the parts upon which there is likelihood of any amalgam eollecting are readily removable and replaceable. Furthermore, the adjustability of the cylinder-hangers upon the standards su )porting them enables the capacity of the well (which.

is regulated by the space between the cylinder and the walls of the well) to be altered at will, so that any desired quantity of quieksilver may be employed. This is of great importance where economy of equipment and voperation must be considered. Moreover, the adjustability of the standards enables the cylinder to' be shifted toward or away from the upper end of the machine, enabling the most advantageous arrangement to be obtained for anygiven conditions under which the machine must be operated.

In addition -to what has been stated with relation to the merits of the improved construction it may be stated that any desired number of sections may be employed in making up a machine and the sections may be iventhe most advantageous arrangement or the conditions under which the machine is to be employed. For instance, the first five sections of the machine might be employed together, in which case only two cylinders would be required and one chain connecting the shafts C3. VThus the sectional construction as herein provided not only renders the machine readily portable-a matter of great importance-but enables the same machine to be taken apart and reconstructed into two or more machines when conditions require.

The amalgam-pans are interchangeable, and usually each machine is supplied with several pans of each size. Any desired arrangement of the pans in a given machine may bemade, therefore. For instance, the machine may be equipped with pans all of the smallest capacity, and the machine may then be,v used for sampling purposes or for regular amalgamating-.work when only a small amount of quicksilver is available.

It will be understood that many changes in details of constructionwithinthe spirit of my invention maybe made. Hence I desire to be understood as intending no undue limitation from the foregoing detailed description.
