shown in Fig. 4. Fig. 6 is an elevation of one of the cam-setting devices with a section of the same feathered shaft as is shown in F lgs. 4 and 5. Fig. 7 is'a transverse sectional elevation of the cam-settin device, together with a portion of the eathered shaft shown in F 1g. 6. Fig. 8 is a broken elevation' of an assemblage of supporting disks, cams, feathered shaft, cam-setting device and main shaft. Fig. 9 is a perspective vlew of a section of the stationary concave grlnding surface of my device. Fig. 10 is a perspective view of a form of section, circumferentially'continuous with the concave stationary grinding surface, and which I preferably use to allow the disintegrated product to pass through. i.

The outer casing of my device is composed of three parts fastened together. The'lower or'larger part shown in Fig. 1 is marked 1. The sections 2 and 3 rest upon sectionl 1 and are fastened thereon, as well as together. The main shaft 4 passes through the center of the machine and has mounted upon it a series of supporting disks 5, keyed to the shaft 4l by the key 6. Between the respective disks and fulcrumed upon the rods 7 are the grinding shoes 8. Engaging the inner ends 9 of the respective slices 8 are the the feathered shafts 11 by the keys 12.

Mounted on the respective featheredshafts 1'1 and contained within hexagonal recesses 13. in the outer one 'of the disks 5, are the respective cam-setting devices 14, which are concentric with each of the feathered shafts 11, and are keyed thereon by the keys 15. The nut 16 secures the cam-setting device 14 upon the shaft 11. The rods I and the shafts 11 are respectively secured at each end and act to hold all the parts supported thereon together. Surrounding the arrangement of disks 5, cams 10 and shoes 8 are the sections of cylindrical partition, which are of two kinds, one marked 17, being adapted for grinding and the other marked 18 being adapted to allow the lfiner particles of the disintegrated product to pass through the saine and to gravitatc into the hopper 19. Mounted within the section 3 of the casing, is the inclined trough 20. The upper ends and sides. as well as the top of this trough 20 are inclosed; the inner side is hung from an oscillating mechanism mounted 011 the i casing 3'and constitutes a valve 21, whereby nalcd in the bearings 2S) and 30 upon the` casing Mounted upon the shaft 24 is the oscillating lever 31, the outer end of which Y' is provided with a slot 32, within which slot verse to is adjustably secured-the pin 33. The lever 31 is actuated by the crank 34 through the means of the connecting rod 35 journaled on the Wrist pin 36 and the pin 33. A radial slot 37 is provided near the outer end of the crank 34, within which is adjustably secured the wrist pin 36. The shaft 38 is journaled in the standards 39 and 40, mounted upon t-he casing section 3. At one end of this shaft 38is secured the crank 34 .while near the other end is mounted the pulley 41. Attachedto the casing section 3 and forming therewith the inlet hopper 42'is the plate 43.

In Fig. 2, the shaft 4 is journaled in the bearings 44, 45, and 46. Between the bearings 45 and 46 and secured to the shaft 4, is the pulley 47. Centrally disposed, transthe shaft 4, is a partition wall 48, which divides the inner space Within the casing into two similarly constructed compartments, 49 and 50, withineach of which, mounted upon the shaft 4, is a complete set of disks 5, 5, cams 10, 10, cam-setting devices 14, 14 and similar attachments thereto as described above in connection with Fig. 1. The lower inner open end of the trough 20 serves as an inlet hopper to the compartment 50, near the pulley 47. The annular recesses 51, 52, 53 and 54 are all concentric with the shaft 4. Vithin the recesses 51 and 52 are supported the sections 17 and 18 of the cylindrical partition within compartment 49 and within recesses 53 and 54 are supported the sections 17 f and 18 of a similar cylindrical partition within compartment 50. These sections of said cylindrical partitions are adapted to fit within the said respective .annular recesses and to be adjustably supported therein in any desired combination of the said sections about and concentric with the Inain shaft `4, and the rotating grinding parts thereon.

In Fig. 3, I have shown transverse milled teeth 55, 55 on the outer curved part of the grinding shoe. This curved part is thickened below as at 56 and is integral with the arm 57. A hole 58 is provided in thearm 57 adapted in relative position and size to receive a rod 7, as shown .in Fig. `1. The lower end 9 offthe arm 57 is concave and adapted to engage the cam 10 of Fig. 1 when in position between the disks 5, 5.

In Fig. 4 is shown one of the cams 10 of Fig. 1, keyed upon a section ofa feathered shaft 11 by the key 59.

Fig. 5 shows a transverse section of the cam 10 with the key 59 partially in position .in the keyway 60 of a feathered shaft 11.

In Fig. 6, the hexagonal cam-setting device 14 is lshown keyed to the shaft 11 by the key 61. A transverse section of the same cam-setting device 14 mounted on the shaft 11 and thekey 61 is shown partially in position along the keyway 60 in the shaft 11; the end 62 being threaded to receive a nut.

In Fig. 8 is shown three of the disks 5 mounted upon 'the shaft 4, together with 'the cams 10, the cam-setting -device 14, the featheredshaft 11 and the nut 63. f

In the perspective view of a section of the cylindrical partition With a sur-face as illustrated in Fig. 9, the transverse teeth 64, 64 are shown milled in the concave face of the said section. -The curved ends'of the sections 65 and 66 are adapted to fit within the annular recesses marked 51, 52, 53, 54, in the flat walls of the casing.

I have shown in Fig. 10 a square wire screen 66 mounted on the concave side of a frame section 67 and secured thereto. The said frame section being adapted on the curved ends to fit within lthe said annular recesses. y

Previous to operating my device, \it isv desirable to set the grindingshoes in governing the space between the rotating, grinding surfaces and inner surface of said cylindrical partition and to arrange the concave sections 17 and 18 within the annular recesses. Each- 'roup of grinding shoes 8, fulcrunied on the rods 7, between the disks 5, is set with reference to the stationary grinding surface of said cylindrical partition by partially rotating the feathered shaft 11 of said group, having previously withdrawn the cam-setting device from its hexagonal socket and placing the said device within the said socket, after attaining the desired position of the cams, then securing all parts together upon the shaft 11, by the nut 63, there being a head on the other end of each shaft 11.

The cam-setting device being` also keyed upon the feathered shaft 11, turns with this shaft 11 and when reinserted within the hexagonal socket .is then in a new position within the said socket after the shaft 11 has been turned as just described. Instead Vof using the hexagonal form for the external shape ofl thecam-setting device, any other regular form concentric with the shaft 11 may be used, providing said form have equal sides and providing the corresponding socket Within the end disk is similar in form and size to properlyengage the said camsetting device. The greater the number of equal sides used in said device, the greater will be the variety of positions attainable when setting the grinding shoes. I have found it desirable to relatively arrange the lsections 17 and 18 around the annular recesses to attain various results in the disintegratedy roduct. The desi I have here shown an adopted in connect-ion with the annula r recesses gives freedom in quickly lnter; changing the said sections. The section marked 68 and shown in perspective 1n Ilg. 10, being preferably woven of square wire, presents a rough concave surface to assist 1n disintegrating the materials within, at the same time allowing the finer particles to pass through and reach the ho per.

In operation the materlal to be disinte-l grated is fed into the feed hopper- 42 and finds its way between the grinding shoes 8 and the concave grinding surface 64, and is artially disintegrated, as itmoves in the direction of the grinding shoes. Continuing over the open section 18 where the rough surface 67 of the section 18 assists in cooperation with the grinding shoes 8 in further disintegrating the material within. The finer particles find their way through this open section and the coarser are carried on to be reground on other grinding sections of said cylindrical partition within the annular recesses or are carried around and ground again and again, the finer particles of material finding their way through the` open sections Aafter they are'formed.

Auxiliary grinding is accomplished by allowing some of the material to pass into the trough 2O and downinto the adjoining grinding compartment 50, where the process is carried on in a manner similar and with similar means to that just described for the initial grinding chamber 49. Thev oscillation of the valve, in-amplitude and period of vibration, forms a positive means of governing the amount of material found desirable to pass into the auxiliary grinding chamber 50. Any multiplicity of auxiliary grinding chambers in addition to the one shown and described, can be arranged along the main shaft 4 to afford any desired result in the disintegrating of materials, and the material can be passed in succession from one to the next chamber as is done from chamber 49 t0 50.
