ROTARY APPARATUS FOR TREATING MATERIALS.

Application filed July 15, 1910, Serial No. 572,132.

To all whom it may concern:

Be it known that I, JO N W. Ho NsEY,

a citizen of the United States, residing at Summit, Union county, New Jersey, have invented a new and useful Improvement-in Rotary Apparatus for Treating Materials, of which the following is a specificatiom'reference being had to the accompanying drawings, in which Figure 1 is a-seotion in perspective of a rotary cylinder equipped with my improvement; Figs. 2 and 3 are similar sections tary apparatus. 1

' My invention is of particular value in.

the treatment of materials which tend to become sticky during the treatment; or must be introduced into the apparatus in asticky or cohesive condition.

I shall herein show and describe my apparatus in the forms which I have found to be preferable for actual use; but it will be understood that many changes may be made, and that the forms here illustrated and described constitute merely preferred embodi-v ments of my invention.

Referring to the drawings, 1 is a section of a rotating cylinder equipped with my apparatus. At various points .inthe cylinder are attached the eye-bolts 3 which are se cured by suitable lock-nuts l, and through the eyes of which pass the hinge pins 5 on which are supported the hinges 6 of the movable buckets or cradles 7. These cradles consist each of'two side pieces 8 andfa series of cups or shelves 9 arranged in ladder fashion from the outer ends of the side pieces to near the hinge ends, and as the cylinder rotates they serve to carry the material upward, and, after having passed a certain position, the Weight of the unbal Specification of Illetters Patent.

anced outer ends of the cradles 7 is sufficient to cause them to fall downward. It is desirable to stop this downward movement abruptly so as to dislodge any material that may have adhered to the cradles. This abrupt stop may be provided for in various ways. o

In Fig. 1 I show a cylinder 2 against which each cradle, as it is elevated in the rotation of the cylinder and falls downward, comes to rest with a sudden jar, thereby dislodging any adhering material. Upon further continuance of the, rotation the cradles fall back against the outer cylinder as before. The inside edges 10 of the cups 9, as shown in. Fig. 1, and the outer edges 11 of the cups 9 and of the side pieces 8, as shown in detail in Figs. 6 and 7 are preferably sharpenedso that when they fall against the inner cylinder 2 (in Fig. 1), or back against the sides of the cylinder .1, they serve to cut away any material adhering to either the cylinder -or' to, the flue, which might otherwise build up and render the cradles inoperative. The motion of the cradles is accompanied by "a blow of consid erablemagnitude as they fall into either position, which assists them in removing the I adhering material, and in cases'where' the inner cylinder 2 is stationary, as respects the cylinder 1, the edges 10 act as scrapers to efl'ectively remove all of the material adhering to the top of the inner cylinder 2. y In. order to increase the force of the blow 7,

produced bythe falling bucket,'I may if I I so desire, weight the outer end of the cradle 7 as shown more particularly by' the weighted portion 7( in Figs. 5'and 6. The inner cylinder may be used to convey heating gases if desired. The blows produced b y the cradles falling against the sides of the cylinder, in conjunction with the cutting action of the sharpened edgesiof the cradles, I have found to be amply sufiicient in all cases" to dislodge anymaterial adhering to the inside of I the cylinder. When the material has become partly dried and agglomerated into distinct masses of some degree of solidity, the cradles alsolser've to 'break,'- crush and grmd up this agglomerated material into smaller particles, so that the resulting product is more uniform both as respects the size of the par ticles and the completeness of the treatment of each particle.

The cup or shelves 9 may be riveted or otherwise attached to the side pieces, as shown in some of the figures, or may be cast integral with them as indicated in Figs. 6 and 7.

In Fig. 2 I show a modified form of stop consisting of stirrups 12 which are hinged upon the pins 5 so as to fold down against the cradles when in their lower position, as shown in the figure. In the upper portion of the cylinder the cradles fall forward as in the arrangement of Fig. 1 and are caught and abruptly stopped by the stirrups 12. In Fig.2 I also show a second set of cradles which are staggered in position as respects the first set, but in all other respects are 7 similar. The objects to be attained by staggering the cradles, are, first, to present a devious path for any fluid which might tend to flow endwise through the lower portion of the cylinder, and, second, to cause the operation of adjoining sets of cradles to take place successively, and thereby the material contained in and adhering to the cups of the cradles is caused to shower down and to be distributed more uniformly, and the formation of voids or blank V-shaped spaces through which a gas traversing the cylinder might pass without interacting effectively with the material contained in the cradles, is to a large extent obviated.

In Fig. 3 I show another modification in which, instead of the movable stirrups 12 I have substituted the rigid stirrups 13, through the extremities of which the bars 14 pass. These rigid stirrups 1,3 are pinned to the rings 15 by the pins 16, which also serve as hinge pins for the cradles themselves. The check rings 15are provided for the purposes described in my companion application filed July 15, 1910, Serial No. 572131, and where it is desired to use both cradles and buckets in the same cylinder the buckets may be attached to one side of the check ring 15 as described in my companion application, and the cradles to the other side. I may also construct my check rings so that either buckets or cradles may be used in connection with them, as desired, in view of the consistency of the material to be treated in the cylinder.

In the arrangements illustrated in Figs. 1' and 2, no fixed check rings'are shown and the side pieces 8, when made broad as shown in those figures, act as check rings.

' In Fig. 4: I show a further modification in which, within the cylinder 1, there is provided a loose rotary cage 17 consisting of the annular side pieces 18 and the buckets 19 arranged in ladder fashion between them and attached to them in any suitable man ner. Upon the cylinder 1 at suitable intervals here shown as 180 apart, I place the projections 20. If the cylinder be rotated in the direction of the arrow, the cage 17 will roll up the projections 20 on their inclined sides 21, and will then fall against the side of the cylinder, thereby producing a blow of sufficient violence to dislodge any material adhering to the cage 17 or to the cylinder 1. This action is in all respects analogous to that produced by the cradles 7, and the outside edges of the buckets 19 and of the cage 17 may be sharpened so as to assist in cutting away the adhering material in a similar fashion. The cage may eX- tend the whole length of the cylinder, or for only a portion thereof, and instead of one long cage there may be a series of shorter ones; and, if itis desired to provide cages for only a portion or certain portions of the cylinder, the cages may conveniently be held in place by making them slightly larger in diameter than the inner diameter of the fixed check rings 15, if such are provided, as shown in Figs. 1 and 5.

All such modifications are obviously within the scope of my invention.

The. speed of rotation of the cylinder should be governed by the character of the material-being treated, and partly by the intensity of the blow or jar which it is desired to produce when the movable buckets or cradles fall upon the stops, for, by regulating the speed of rotation I have found that I can regulate the intensity of the blow to a nicety. g

What I claim is:

1. In apparatus for treating materials, a rotating chamber, shelves rotating with said chamber and adapted to lift and drop the material under treatment, supports for said shelves, and means for causing such shelves to move with relation to said cylinder and means for abruptly stopping such motion.

2. In apparatus for treating materials, a rotating chamber having therein a series of pivotally mounted cradles and means for arresting the movement of said cradles during the rotation of the cylinder.

8. In apparatus for treating materials, a rotating chamber, a series of cradles pivotally mounted therein and a series of coacting stirrups secured to said vessel in which said cradles are mounted, and acting as stops.

4. In apparatus for treating materials, a rotating vessel containing a plurality of buckets for elevating and distributing the material, said buckets being movable with relation to the vessel,

5. In apparatus for treating sticky materials, a rotary vessel containing a plurality of buckets for elevating and distributing the material, said buckets being adapted to shake prevent the sticky material from adhering loose the sticky material during the rotation either to the interior of the vessel or the of the vessel. buckets.

6. In apparatus for treating sticky mate- 7 JOHN W. HORNSEY. rials, a rotating Vessel containing a plurality Witnesses: l of buckets for elevating and distributing the R. I. MIDDLETON, material, and means Within said Vessel to G. HANSEN.
