MANUFACTURING COMPANY, or IOFOHIOL" ful Improvement in Cinder-Mills, of which the following is a fullfclear, and exact de scription, reference being had to the accom- T panying drawings.
Th1s invention isintended especially for use in foundries for thepurpos'e of, economically crushing cinders and recovering the metal and coke contained therein.
The mill shown in the drawings embodying the invention is a development of and improvement upon the mill which is described and claimed in my prior patent, No. 514,097, the primary object of the invention being to increase the efliciency of the mill.
The invention consists in the construction and combination of parts shown in the drawingis andhereinaft'er described and claimed.

Fig. 4 is an enlarged perspective inside view of the dischargeehead of the mill. Fig. Sis a longitudinal vertical section of the mill when empty, and Fig. 6 is a longitudinal horizontal section of the mill. containing-material to be acted on. 7
Referring to the parts by letters, A represents a rotatable drum having the two ends The two heads are respectively provided with two hollow trunnions b and c, u on which the drum rotates,
said trunnions eing mounted in suitable bearings. Water is pumped in through the trunnion c, and the lig t particles of the cinder crushed in the mill, as hereinafter explained, pass out through the trunnion-b, the heavy uncrushed particles remaining in the mill.
The structure is particularly designed to feed the materialcontin ually away from the exit and so that it shall not clog the outlet. This will be fully explained.
On the head 0 is preferably an external gear 0, by which the drum may be rotated.
lihe two heads are preferably cast in' the Spcificationof Letters Patent. I Application iiled lliarch 21, 1905. Serial N0. 251,24ii. s

'7 form shown, the: body portion, which maybe made of sheet metal, is secured to them. The drum tapers slightly from end'to end being. smallest at the discharge end, whereby the body portion is attached .toEthe head B. A perforated partition F,- is preferably'secured to an. annular flange a on the inner face of the head C, thepurpose 'of the partition being to prevent the material in the rum fromworkingbackward and out'through the hollow trunnion c;
The head B has peripheral-cylindrical flange 1), which fits within thebody a and is secured thereto. There is also a concentric cylindrical flange Iii-projecting inward from the end plate of thehead, the diameter of this flange being preferably'somewhat more than half theYdiameter-of the'flange b." A circular plate e is secured to the flange bf, and this plate, togetherwith said flan e, c'on'stitutes a cylindrical chamber E, w ich communicates directly with the hollow trunnion b. In the annular space between the flanges b and b are a plurality of pockets H, and in the flange b are a plurality ofopenings'e', each leading from one of' said pockets into the cylindrical chamber E.- r The only wayin which anythin'gjimthe drum can pass'tdthe outlet in'the" trunnion b is throughsaid;1 ockets and openings 6 into chamber hese pocketsare formed by blocks M," which project inward from=the inner face of the endplate of the head B and extend from the flange b to the flange, 11
Each of these blocks joinsaid end late near one edge of a hole a and exten' s slightl ast the next adjacent hole e. Each bloc isundercut adjacent to the last-mentioned hole e. The outer surface of each 'bl'ockcommunicate with, the chamber "throughthe holes a.
' that is to say, the surface whichfaces the interior of the drum is inclined at 'anangle of Within the nii'nj 'aiilygaotibl ant er K. In the for'inshown it iscomposed, oftt wo head It will be understood that this mill is to be charged with the cinders to be treated through an gpening which the cover-plate D Wl'll close. he drumbeing charged and the door being tightly closed, the drum is rotated in the direction indicated by the arrow in Fig. 2. A stream of water is pumped through the drum into the trunnion c and out through the trunnion b to maintain the water-level at about the axis of the drum.
As the drum rotates the crusher Will be carried up with the cinders a short distance and will then drop backward and in so doing will crush some of the cinders. The .cinders will be carried up by the mill, and the surfaceof the cinders will occupy substantially the position indicated by line H H, Fig. 2. This leaves an approximately triangular space below the water-level on one side of the mill and between the water-level and the top of the charge of 'cinders and extending from one head to the other. pulverized the water will take up the'pulverized part thereof and will float it ofl, passing into the several pockets and through \he openings cf into the cylindrical chamber ll and thence out through the hollow trunnion 1). Of course the metalwill not be finely pulverized, More or less of it, however, will fall into the pockets referred to;
but as. the drum continues to revolve all such metal will fall by gravity out'of these pockets back into the drum. This operation will go on until all of the cinders are pulverized and carried off, leaving only the metal in the drum.
The object of tapering the cylinder and locating the outlet in the smaller end is to cause the metal and heavier matter to gravitate away from the outlet, while the water suspends and carries with it the lighter matter toward the outlet. The crusher is tapered for a similar purpose. The larger end will travel faster than the smaller one. Therefore it will always be, in advance, assuming a position somewhat diagonal tothe axis of the cylinder, as shown. in'Fig. 6. The crusher being in the diagonal position, the trough-like spaces between the blades convey whatever is contained therein in a direction opposite to the outlet, while' the watercurrent carries what it has in suspense toward and out As the cinders are through hollow trunnion. The coke being light enough to be carried by the water passes out as 'fastas it is liberated from the slag without being materially reduced in size. It is thereafter separated from the dirt and water by suitable means. (Not shown.)
Having described my invention, I claim a interior of the drum, the said flange having openings through it pockets.
2. In a cinder-mill, the combination of rotatable drum, which is in the form of a truncated cone and which has an axial inletopening through the larger head (,1 and an axial discharge-opening through the smaller at the bottoms of said head B, with a flange projecting into the cylinder from head B around said dischargeopening, a plate fast to said flange and forming, with it and the head, a chamber E, a plurality of blocks secured in the space between said. flange and the wall of the drum in contact with head B and extending therefrom at an acute angle, thereby forming pockets which communicate with the interior drum, said flange having openings through it at the bottoms of said pockets, whereby communication is established between the bottoms of said pockets and chamber. E.
3. In a cinder-mill, the combination of a rotatable drum, which is in the form of a truncated cone and which has an axial inletopening through the larger head 0 and an axial discharge-opening through the smaller head B, a flange projecting into the cylinder from head B around said discharge-opening, a plate fast to said flange and iorming, with it and the head, a chamber E, a plurality of blocks secured in the annular space between said flange and the wall of the drum in contact with head B and extending therefrom at an acute angle, thereby forming pockets which communicate with the interior drum, said flange having 0 enings through it at the bottoms of said 00 rets, whereby communication is establis ed between the bottoms of said ockets and chamber E, with a crusher Whic .is of gradually-increasing diameter from one end to the other andhas a series of' longitudinal outwardly-projecting blades, said crusher being placed loosely within the drum with its larger end adjacent to the smaller end of the drum.
