It is the object of my invention, among other things, to produce an apparatus of this character wherein the water within the barrel may be discharged from the side thereof rather than through perforations in its periphery, as has heretofore been the practice; to mount the upper of the crushing rolls so that it may have great ease of movement and flexibility; and in other ways to materiall .improve the pulverizing devices hereto ore made.

To these, and other ends, my invention consists in the pulverizer having certain details of construction and combinations of parts, as will be hereinafter described and more particularly pointed out in the claims.

Referring to the drawings, in which like numerals of reference designate like parts in the several figures;

Figure 1 isa front elevation, partly in section, of an apparatus embodying one form in which my invention may be constructed;

Fig. 2 is an end view thereof, taken upon line af-b of Fig. 1;

Fig. 3 is a sectional elevation thereof, taken upon line c-d of Fig. 1;

Fig. 4 is a fragmentary end elevation looking toward the right of Fig. 1;

Fig. 5 is a sectional view vof the drum, taken upon line e-f of Fig. 3; and

Fig. 6 is a fragmentary view of the settling tank and the over-flow trough connected therewith. f

Heretofore the barrel or drum has been provided with a plurality of openings in its outer shell through which the water enters the barrel, but in some classes of work this is objectionable, because the holes become clogged and the water does not enter the barrel in sufficient quantities to do effective work, and again, the upper of the crushing rolls has been so mounted that it moves in substantially a straight line and thereafter does not bear with equal pressure upon the lower crushing roll at all times. I have obviated bothof these disadvantages 1n this inventionby providing means for supplying the barrelwith water without admlttrng it through apertures in the outer shell thereof, and also by making the upper of the crushing rolls more flexible in its aca tion, and so mounted that it always bears with equal pressure uponthe lower crushmg roll.

In the practice of my invention I prov ide a pairof substantially parallel uprlghts 1%1, to which is attached a circular head plate 2, which forms a stationary end for the barrel. The barrel 3 has upon opposite ends thereof the external annular anges 4 and 5, which are in frictional contact withf the rollers 6 that are journaled in the adjustable bearings 7. A shaft 8 is rotatably mounted in the head plates 2, and fixed thereon is a crushing roll 9. Upon the outer end of this shaft is a gear wheel 10, the teeth of which mesh into those of the pinion 1l fixed on the shaft 12. Fast and loose pulleys 13 are fixed on this latter shaft and thereby provide convenient means for rotating all of said shafts and the crushing roll 9 through the middle of a plate, as is common in the art. An auxiliary shaft 15 is rotatably mounted in a bracket 14. attached to one of the frames 1 and fixed thereon is a sprocket wheel 16, which is operativel connected with a sprocket pinion 17 upon the shaft 8 by the chain 18. Also fixed upon the shaft 15 is a pinion 19, shown by dotted lines in Fig. 2, both of which mesh into those of the internal gear 20 on the flange 5. l

By the means above described the barrel 3 is rotated and the crushing roll 9 at one and the same time, and through the action of the shaft 8.

A second crushing roll 21 is fixed upon the shaft 22 journaled in the yoke 23 that is movably mounted upon the shaft 24. journaled at its opposite ends in the brackets 25. These brackets are fixed upon the inner faces of the plates 2. This second crushing roll 21 bears by gravity against the roll'9 and through its pivot mounting is moved toward and away from the roll 9, its relative position depending upon the quantity of material passing therebetween.

In one of the plates 2 is an opening 26, l

through which the slag cinder is fed into the barrel and for convenience in deliverin the cinders into the barrel, I have provided a feed chute 27 that is pivoted to one of the head plates 2 at 28 and is secured in this position byna latch 29 on the spindle 30, which engages a lug 31 upon the chute.

The cinder as it falls into the barrel is deected byfthe guard 47 and accumulates upon the bottom of the barrel. It is then carried upwardly by the pallets Y32, which discharge the cinder by gravity upon an apron 33, which ismounted upon said spindle 30 and guides the cinder between the crushing rolls 9 and 21. After passing between the rolls the crushed cinder drops onto the bottom of the barrel and is again carried up by the pallets and recrushed, which operations are repeated until the contents of the barrel are discharged by means hereafter described. L

A water trough 34 is arranged so that the drum rotates therein and adjacent thereto is a settling tank 35r connected with the trough 34 by a spillway 36, over which the water flows fromsaid settlin tank into said trough. Within the barre between the outer walls thereof and the inner walls38 are a plurality of inner chambers 37, which are radially separated from each otherfby partitions 39. During the rotation of said barrel water is admitted into the chambers 37 from the trough 34, throughthe openings 40 in the outside of the barrel and is discharged into the barrel through the openings 41 upon the inside? of the barrel. When the water in the barrel arrives at the level of the openings 48 in the plate 2,see Fig. 3, it overiows onto the spout 43 and is discharged into the settling tank 35, from which it flows back into the water trough over the spillway 36. By this method of water distribution the water in the barrel is maintained at a level higher than that in the trough, is being continually used and no new supply is required,thereb providing means for operating the device at the minimum expenditure for water supply. Afterpassing between the rolls the light particles of the cinder mass by the action of the water in the barrel and by its agitation are carried into the settling tank through the opening 48, and the heavy particles, which contain the metal, sink to the bottom of the bavifel and are again carried up and passed bet e cessive crushing operations.

As the cinders are always wet when presented to the rcrushing rolls, there is no dust in the operation of my device. It may be used, however, for dry grinding if desired, l use'I may provide a hole 46 in one of the heads 2 to receive a dust iue leadin yto a suitable exhaust device (not shown by means of which the dust is drawn en the` rolls, being continually subjected to suc- Lasalle 0H. After the cinder has been sufficiently ground the barrel is emptied by swinging the apron 33 through the manipulation of the handle 44 to the position shown by dotted lines in Fig. 3. In such position the material is deflected onto the stationary chute 45 in the barrel and over which the apron 33 normally lies. As the bottom of this chute is inclined downwardly the material slides onto the swinging chute 27, which is in theposition shown by dotted lines in Fig. l, and thus forms a continuation of the chute 45.

Within reasonable limitations various modifications of my invention, aside from those herein suggested, may be adopted, and will readil suggest themselves to any erson skille in the art. I would there ore have it understood, that I do not limit myself to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of my invention.

What I claim as new and desire to secure by Letters Patent, isz- 1. In a crushing apparatus, the combination with a barrel; of a water trough, means for rotating said barrel so that a thereof passes through the water in said ortion f water trough, and means'connected with water in said trough whereby water `will enter said chambers from said trough and kwill be delivered intosaid barrel.

3. In a crushing a paratus, the combination with a barrel aving a plurality of chambers therein adjacent to its periphery, each of said chambers having openings adjacent to the op osite ends thereof, the o ening in one end being through the outsi e of said barrel and at the opposite end through the inside of said barrel; of a water trough, and means for rotating said barrel within said trough, so that the openings into said chambers through the outside thereof pass through the water in said trough.

4, In a crushing apparatus, the combination with a barrel; of a water trough, means for rotating said barrel in said trough so that water may be takeny vup from said trough vand conveyed to the inside of said barrel and discharged therefrom at a level higher than the water in said trough.

5. In a crushing apparatus, the combinanaomi tion with a water trough; of a settling tank adjacent thereto and ha connection therewith, whereby water in said settling tank will flow into said water trough, a barrel, means for rotating said barrel so that the periphery thereof passes through the water in said water trough, a discharge opening through one side of said barrel between the periphery and the axis thereof, said discharge opening being at a oint in a plane higher than the Water in sai trough,

and means connected with said barrel for taking water from said trough, dischar 'ng it into said barrel, and discharging it om said barrel through said discharge openn 15 In testimony whereof I have hereunto a fixed my signature.
