6 Claims.

invention relates generally to improvements in machines for the treatment of sand,

gravel,

materials.

One of its objects is stone and like materials, and particularly to a machine for washing and scrubbing such the provision of a machine of this character designed to produce a thorough and eficient scrubbing action and one which is designed to eifectually handle either light or heavy loads.

Another object of the invention is to provide a scrubbing apparatus which is simple, compact and rugged in construction,

which is positive and reliable inoperation, and which affords a maximum capacity at a minimum consumption of water and power.

In the accompanying drawings:---

Figure 1 is a perspective view of the scrubbing apparatus embodying my invention. Figure 2 is detailed cross section through one of the troughs and taken in the plane of line 5-5, Figure 3. Figure 6 is a similar view taken on line 66, Figure 3.

Similar characters of reference indicate corresponding parts throughout the several views.

In connection with the invention, a vibratory or shaking body or carrier is provided, including a plurality of substantiallytrough-shaped scrubbing decks 10 which lengthwise of the are disposed side by side machine in transversely stepped-like fashion and symmetrically about the longitudinal axis thereof, as shown in Figures 1 and 2. This gyrating body may substantially horizontalor slightly inclined position and is supported andibalanced for vibratory movement on a centrally disposed longitudinal rotary shaft 11 supported at its ends in suitable bearings 12 mounted on a frame structure 13 of any appropriate construction. This shaft con stitutes the drive element of the machine and imparts to the scrubber body a positive circular or gyrating movement at right angles to the shaftaxis, whereby all points of the body are vibrated in a circular path or orbit, and to this end the shaft has eccentric portions 14, as seen in Figure 4, on which said body is supported, the latter having rollers or like bearings 15 arranged in housings 16 secured to transverse plates 17 depending from the scrubber body at points adjacent the ends thereof.

For the purpose of maintaining the be disposed in a machine in proper balance, the shaft 11 is provided with counter-balanced wheels 18, and to steady and hold the scrubber body in its proper balanced position on the shaft its opposite side portions are yieldingly suspended or supported by 5 seated at their lower ends on supporting members 21 applied to the frame structure 13, in the manner shown in Figures 1 and 2.

As shown in Figure 2, the scrubbing decks 10, which are substantially parallel to the operating shaft 11, are disposed symmetrically in a collective substantially peaked formation and in suit- 15 able spaced relation over and about the top and adjoining sides of the shaft. In the example shown, two troughs are disposed side by side and at the same elevation centrally over the shaft, while below these troughs and at opposite sides of the shaft are two additional troughs arranged in stepped relation. The lower portion of each preference, approximately section and fitted therein shell 22 spaced from the surrounding wall of the deck and preferably constructed of wire mesh or like material. The material to be cleaned engages this shell, which latter provides a roughened surface to produce a combined screening and scrubbing action as the material travels along the decks, the foreign or removed material dropping through the screen section into the bottom of the deck and. being washed away by the water which is used during the cleaning and scrubbing operations. Adjacent their discharge ends or, if desired, at other points along the length of the decks, openings 23 are provided through which the foreign matter and wash water are discharged.

The material to be scrubbed or cleaned is delivered to the decks at the upper or left hand end thereof by a feed hopper or like device 24, shown by dotted lines in Figure 2, and for the purpose of efiecting'a proper distribution of the material from the first-named wall. The lower edge of the bridge wall 27, as shown in Figure 2, is notched as indicated at 28 over the respective scrubbing decks to provide resulting openings or passages through which the material is conducted from the 5:

'body in substantially circ zontal axis, and a plurality of relatively narrowr,

compartment 25 into the respective decks. As shown in Figure 2, the hopper 24 is disposed over the central decks l0 and any overflow of the material into the compartment 25 is permitted to iiow by gravity into the adjoining stepped troughs or decks, thereby enabling the handling of fluctuating loads in an efiicient manner with a uniform distribution of the'material.

As the material, travels lengthwise of the troughs, the gyrating body of the machine combined with the circular bottoms of the troughsections 22 imparts to the material a tumblinglike action, the particles of material taking a loop or spiral-like course through the troughs, asindicated by the arrow in Figure 5, with the result that the particles of material rub against the trough-walls and against one another to effectually loosen and remove the clay matter from the material. During this operation, sprays of water are played upon the material as it flows through the troughs. a

Disposed transversely of thetroughs at suitable intervals lengthwise thereof are a plurality of bafile walls or plates 29 which are preferably provided to intercept and govern thev flow of I the material as it travels through the trough and not only momentarily retardsuchmovement but also cause the material to be impacted against the same and contact with the edges thereof to there by assist in the removal of-foreign matterfrom the material. At the discharge ends of the troughs are arranged closure plates or bridge-walls 30 which extend to the bottoms of the troughs while their upper edges terminate at a suitable distance abovethe bottoms, and while'retardingth'e discharge of the materials from the troughs to assure its thorough scrubbing, eventually permit it to pass over the top edges of these plates and empty into a suitable receptacle provided for receiving it. 7 1 For the purpose of controlling or regulating the rate of flow of the material through thescrubbing decks and'of governing the capacity of the machine for the different materials to betreated,

I preferably mount the baffle walls 29 so as to be readily adjustable vertically or in the direction of depth of the decks. While-anyappropriate means of adjustment may be employed, I have shown each baffle wall mountedon a transverse support-- ing bar 31 secured at its ends to the sides of the respective deck and having bolts 32 engaging upi treated applied 'to-said body and extending genright slots 33 in said wall. a

I claim as my invention:-'- '1. 1. A machine of .the character described, comprising a gyrating body, means for gyrating said" ular pathsabout ahorisubstantially trough-shaped receiving. decks for the material to be treated applied to'said body and extending. generally in the direction of .its

or other foreign gyrating axis and disposed in stepped relation on opposite sides of such axis.

2. A machine of the character described, comprising a gyrating body, means for gyrating said body in substantially circular paths about a horizontal axis, and a plurality of substantially trough-shaped receiving decks for the material to be treated applied to said body and extending generally in thedirection of its gyrating. axis and disposed symmetrically about the same in stepped the other on opposite sides of such axis.
