FIGS

WITNESSES 76 Q2 INVENTOR P M ATTORNEY to a less and less degree of fineness. It is this fact which makes adjustability such a desirable feature in the construction of this type of apparatus. When such wear occurs in my improved device, it is only necessary to remove the split collar 1112 by loosening the nuts 18, and then to slide the hubs 78'toward each other along the shaft 1, thereby Withdrawing the heads or flanges 9 and 10 from the studs 25. This action will release the cams so that the cams and the connected studs may be withdrawn from the heads or flanges 4 and 5 and turned through 90 or 180 as may be desired, and then reinserted into the heads 4 and 5, whereupon the other two flanges or heads are replaced, the split collar again bolted in position and the device is once more ready for operation. It will be obvious that the turning of the cams through 90 or 180 will permit the hammers or heaters to progress away from the shaft 1 through the action of the cam surfaces, and that the square studs entering the square holes in the two sets of flanges or heads will lock the cams in the desired new position. This change in the effective eccentricity of the cams will place the hammers or beaters into such a position that the outer periphery of the bars 10 is again in its proper relation with respect to the casing when the hammers or heaters assume the position shownin Fig. 1 under the influence of centrifqgal force. The wear is thus effectively -cm i'rngreiisated. It will be evident, of course, that by changing the number of sides of the studs 24 and 25, finer adjustment and a greater number of degrees of adjustment may be obtained. In Fig. 1 I have shown the parts in their normal initial position,.

so that the eccentricity w is in its most remote position with respect to the main shaft 1. The limitin position, or position of maximum adjus ment with this type of cam and stud, will obviously be obtained when the cams are each rotated through 180.

In Fig. 4 I have shown a modification in which the cam 23 is provided with a main stud 28 of circular cross-section and a supplementary locking pin 29 which is adapted to enter one of a series of circular holes 30 in one of the heads or flanges, these holes being equidistant from the center of the stud 28. It will be obvious that adjustment of the cam may be obtained by placing the pin 29 in any one of the several holes 30, thereby varying the effective eccentricity of the cam. The fineness of the adjustment will depend upon the number of holes 30 provided.

Fi 5 illustrates a further modification in w ich the inwardly projecting stud 25 is similar to that already described, while the outwardly-projecting stud is replaced with a stud of circular outline 31 entering a circular hole 32 in the outer fixed flange 4 or 5, as the case may be. The stud 25 has projecting inwardly from it an extension 33 of circular cross-section such that it may be inscribed within the periphery of the stud 25. In adjusting this type it is only necessary to slide the movable flange 9 or 10, as the case may be, inwardly into the position illustrated by the dotted lines in Fig. 5 and then to rotate the cam through the desired angle in any suitable manner, as by introducing a thinspanner wrench between the leg 20 of the hammer or beater 9 or 10 as the case may be, whereupon the movable flange 9 or 10 may be restored to'its normal position, thus locking the cam in place through the engagement of the lug 25 with the noncireular hole 27 in the flange 9 with which it engages. a

While I have illustrated and describedonly certain specific embodiments of my device, I realize that it is susceptible of wide application, and I do not desire to be limited to the precise structure shown and described.

Having thus described my invention, what I claim is:

1. In a disintegrator, a rotary member, a fixed head and a laterally movable head mounted thereon, a hammer and means for adjustably mounting said hammer upon the rotary member, includinga cam journaled in and supporting said hammer, said cam being supported by said heads and having a locking means engaging one of said heads and held in adjusted position thereby.

2. In a disintegrato'r, a driving shaft, a fixed head on said shaft, a movable head adapted to slide longitudinally on said shaft but rotating therewith, a hammer and means for adjustably mounting said hammer between the heads, including a cam and opposed projections therefrom one of which is non-circular adapted to engage, respectively, with the fixed and movable head.

3. In a disintegrator, a driving'shaft, a fixed head thereon, a movable head thereon adapted to slide longitudinally on said shaft but rotating therewith, a hammer and means for adjustably mounting said ham mer upon said heads, including a cam journaled in said hammer and a non-circular projection extending lon 'tudinally be end said cam and adapted to e located in xed, illdjlsted position by said fixed and movable ea s.

4. In a disintegrator, a main driving shaft, a pair of fixed heads thereon, a pair of movable heads mounted between said I fixed heads and adapted to slide longitudinally along said shaft but rotating therewith, a U-shaped hammer having legs adapted to enter between the adjacent fixed and movable heads, means for adjustably mounting said hammer upon the heads, and spacing means for locking said movable heads against sliding on said shaft.

heads but releasable said pair of fixed heads thereon, a pair of movable heads mounted between the fixed heads and adapted to slide longitudinally along said shaft but rotating therewith, a U-shaped hammer having legs entering between the adjacent fixed and movableheads, means for adjnstably mounting said ham- Iner u on'said heads, includingacam' having a ocking member'engaging one of said by slidlng said movable head away from said fixed head and spacin means for retaining said movable -heads in lockedoperative position. v
