I zen'of the United States, residing at'Salt Lake -City, in the county of Salt'Lake and State of Utah, have invented new and useful Improve- 'm'entsin Sand and Slime Separators, of which the following is aspecification.

,- My invention relates 'to certain new and 'use ful improvements in separating-machines designed, essentially, for working materials containing precious metals and wherein the separation ofjthe sand and slime is effectedautomatically; and my invention consists of the parts and the constructions-and combinations ofparts, which Iwill-hereinafter describe and clai An. essentialcharacteristic of my present invention is the-provision of ia wheel or revoluble member-having pockets or compartments into i which agitated pulp is delivered through a pipe or launder, sai' wheel being periodically rotated, whereby when a conipartment of the bucket is filled theoverflow will automatically trip areleasing mechanism and allow the wheel to turna distance sufficient to bring a succeeding empty compartment beneath the supply and to allow the a material in suspension inthe preceding compartment to be poured off, the heaviermaterial remai ng at the bottom'of the comparts.

' ment' and I eing discharged therefrom when .the compartment is substantially inverted.

' 1"I illustrate one form of. such frame and which frame is provided with vertical standards, in the upper portions of which a hori zontal shaft 10 is appropriately mounted. Upon thisshaft'is mounted or'supported the separating-wheel B, comprising end disks 11 and radially-arrangedpartitions 12, which "I divide'the wheel into a series of separate comthe material to be separated.

in efiect, mounted upon substantially a counterbalancedlever whose fulcrum isthe shaft or rod. p

The swinging launder is connected above its axis withione' end of a rod 24, whose opposite end is connected with a pivoted plate 25,

located in the launder 14 and by which when l I the launder 16 begins to swing outward the flow of the pulp from the launder is diverted from the compartment of. the wheel just filled into the succeeding compartment.

"Projecting from one of the end disks the compartmentewneel are a number of pins 26, I

1 'der, 1'4, in which position the parts are nornmally held and until the overflow from this from falling upon the partition next below it,

one for each compartment and located relative thereto, so that one of these pins will contact with the bent end'27 of the shaft or rod 22, and thus stop the revoluble movement of the, wheel at such a point that the uppermost empty com artmentwill be in line with the discharge 0 pulp from the launcompartment overcomes the counterweighted launder and its adjuncts and moves the shaft or rod to permit the engaged pin to escape past the bent end of the shaft, and thus allow the wheel to make its partial revolution. Another series of pins 28 is provided, also projecting from the end disks of the wheel, and these pins are designed to successively engage exterior bent arms 29, which form a part of a suitable inclined apron 30, so placed that it normally enters thecompart' ment of the wheel next below the compartment being filled, whereby theoverfiow from said last-named compartment isprevented but is directed u on the apron and by the latter is in turn irected into an appropriate trough or launder 31, arranged below it. The apron is pivotally mounted at 32 in the base of the main frame and has a leverarm 32.

upon which. a weight is adiustably mounted, thereby ccenterweighting the apron and automatically returning it to normal position after it has been pushed forward by the par tial rotation of the wheel and the pushing ac-. tion of the pins 28, before mentioned.

1n connection with the trough or launder 31 I prefer to employ a splasb-plate'32, Fig. "3, for receiving the splash from the apron and conducting the slime to the trough 31.

In a separator of the character described it will be found useful to provide means for governing the movement of the wheel, and while various forms of governors may be used in connection with the wheel and other parts heretofore described and two forms of g ov ernors are shown in the drawings I prefer to use a governor of the general type of a dash pot. Accordingly in Fig. l I illustrate a governor which comprises an exterior cylinder or vessel 33, adapted to contain Water or other fluid. Within this cylinder and oper" ating somewhat on the order of a piston is a hollow cylinder or vessel 3 closed at the top and having a relatively small opening in its bottom, said inner cylinder or vessel having an opening in its closed top controlled by an outwardly-opening valve 35. An air-cock 36 is also fixed in the top of the inner cylinder or vessel and controls the rate of movement of said vessel. w i

The inner vessel 34is connected-by a rod or link 37 with one end of a lever 38, fulcrume'd "any other desire at or about its center to a standard 39, rising from the base-frame, and the opposite end of i the lever is likewise attached to a second governing device comprising inner and outer cylinders 33 34 and connect-ions similar to those before described. These two sets of cylinders form an alternately acting governor, and when the inner cylinder of one is elevated the corresponding cylinder of the other is lowered, as I will presently describe. To communicate the partial rotation or the wheel to the governor mechanism, I. show fixed upon the axis of the wheel a large gear- Wheel 40, and in a standard 41 I journal above the gear-wheel 410 a pinion 42 of such size relative to its engaging gear-wheel that a one-half revolution is effected while the separator-wheel B c ves from one position to osition or in the eightcompartment whee (represented in Fig. 3) while the separator-wheel makes a oneeighth revolution. If this wheel consists of more or fewer compartments than shown, the gearing is arranged accordinglv T he shaft of the pinion or smaller gear-wheel 42 is provided with a crank 43, which connects, through the medium of the rod or link 44,

with the centrally-fulcrumed lever, whereby as the separator begins its movement to unloadafilled compartment and bringan empty compartment in position beneath the sand and slime supply the described governor connections result in rocking the lever 38 to ele- Vflf E the then lower and filled inner cylinder of one girverning device and at the same time lower the like cylinder of the other and com anipn governor. When the filled cylinder is thus being raised, the contained water or fluid will pass out of it through the bottom opening and into the outer cylinder and air will enter the inner cylinder through the valve 36, and when the inner cylinder of the other governor is being lowered the water or fluid in the outer cylinder witlrgvhich it connected will be is laced and will enter said inner vessel an relieve any sudden shock or movementwhich might be given the compartment-wheel. The amount of aircushion and the corise uent speed at which the inner cylinder may lower is controlled by the air-cock 36' before mentioned. 1

In Fig. 4 1 illustrate a modified form of governor employing the alternately-acting cylinders before mentioned; but in this case the actuating devices are somewhatmodified. For instance, instead of the toothed gears of Fig. 1 I show insaidTig. 4 groups of pins 4., located relativejroeach com artment of the separator-wheelhnd adapts to engage pins or teeth 46 on the enlarged head 47 of a fulcrumed lever 48, there being in practice two levers and two groups of pins and two pairs of governor-cyliuders and the parts being so arranged in practice at opposite ends of the separator-wheel tnat one set is operating when other set is idle.
