To all whom it may concern.- Be it known that I, FREDRIGK L. KINBEY, States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new an useful Improvements in Grinding and Disintegrating Machines; and I do hereby declare the ollowing to be a full, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form part of this specification.

Like figures of reference refer to like parts.

My invention relates to improvements in grinding and disintegrating machinery of the rotary type; especially to means for governing the amount of space between the respective grinding surfaces and to means of governing the discharge of the disintegrated product. p

The objects of my invention are to provide adjustable and positive means for grindand disintegrating materials, as well as to govern the discharge of the said materials rom between the grinding'surfaces.

I desire also to so construct and arrange the various members of my device that they can, with ordinary mechanical skill, be easily disassembled, repaired, or replaced, reassembled and adjusted in a-convenient manner, which shall lend to [practical utility in its continuous service an as-an article of manufacture.

To attain the above objects, Iprovide certain details of construction, which are illustrated in the accompanying drawings and are hereinafter described. Their coiiperation is explained and what I claim is set forth.

In the figures, I have shown a vertical device assembled in Figure 1. In Fig. 2, I have shown a front elevation partially broken away to illustrate the internal arrangement of the parts. Fig. 3 is a perspective view of one of the grinding shoes composing the rotary grinding surface. Fig. 4 is an elevation of one of the cams, showing in section the feathered shaft upon which it is mounted. Fig. 5 is a trans verse sectional elevation of the cam and shaft shown in Fig. 4. Fig. 6 is an elevation of one of the cam-setting devices with a see tion of the same feathered shaft. as is shown in Figs. 4 and 5. Fig. 7 is a transverse sectional elevation of the cam'setting device, to-

gether with a portion of the feathered shaft shown in Fi 6. Fig. 8 is a broken elevation of an assem lage of supporting disks, cams, feathered shaft, cam-setting device and main shaft. Fig. 9 is a perspective view of a section of the stationary concave grinding 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 through.

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 section 1 and are fastened thereon, as well as together. The main shaft 4 passes of the machine and has mounted u on it a series of supporting disks 5, keye to the shaft 4 b the key 6. Between the respective disks an fulcrumed upon the rods 7 are the grinding shoes 8'. Engaging the inner ends 9 of the respective shoes 8 are the cams 10, WhlCll lie between the respective disks 5.

These cams 10 are looked upon the featheredshafts ll by the keys 12. Mounted on the respective feathered shafts 11- and contained within hexagonal recesses 13, in the outer one of the disks 5, are the respective cams setting devices 14, which are concentric with each of the feathered shafts ll, and are keyed thereon by the keys 15. 4 The nut 16 secures the cam-setting device 14 upon theshaft 11. The rods 7 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 finer particles of the disintegrated product to pass through the same and to gravitate into the hopper 19.

Mounted within the section 3 of the casing,

.is the inclined trough 20. The upper ends disintegrated product to passthrough the center and sides, as well as the top are inclosed; the inner side is hung from. mounted on the an Oscillating mechanism casing 3 and constitutes a valve 21, whereby a limited amount of the disintegrated product is allowed to enterv the trough 20. The oscillating mechanism above the valve 21 is made up of the following parts; rocking arms 22 and 23, which-are mounted on a shaft 24 connect with the valve 21 by the links 25, 26, 27, 28. The shaft 24 is journaled in the bearings 29 and 30 upon the casing 3. Mounted upon the shaft 24 is the oscillating lever 31, the outer end'of which is provided with a slot 32, within which slot 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 ournaIed in the standards 39 and '40, mounted upon the casing section 3. At one end of this shaft 38 is secured the crank 34 while near the other end is mounted the pulley 41. Attached tothe casing section 3 and formin 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 securedto the shaft 4, is the pulley 47. Centrally disposed, transverse to the shaft 4, is a partition wall 48, which divides the inner space within the easing into two'similarly constructed conipartments, 49 and 50, within each of which, mounted upon the shaft 4, is a complete set of disks 5, 5, cams 10, 10, can1-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. Within 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 and 18 of a similar cylindrical partition within compartment 50. 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 concentarate with the main shaft 4, and the 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 the arm 57 adapted in relative position and size to receive a rod 7, as shown in Fig. 1. The

of this trough 20 These sections of said' rotating grinding parts the key 61.

trated in lower end 9 of the arm 57 is concave and adapted to engage the cam 10 of Fi 1 when in position between the disks 5,

In Fig. 4 is shown one of the cams 10 of Fig. 1,.keyed upon a section of a 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 shown keyed to the shaft 11 by A transverse section of the same cam setting device 14 mounted on the shaft 11 and the key 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 feathered shaft 11 and the nut 63.

I In the perspective view of a section of the cylindrical partition with a surface as illus- '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 fiat wall 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 the said annular recesses.

Previous to operating my device, it is desirable to set the grinding shoes 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 group of grinding shoes, fulcrumed 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 feath ered shaft 11 of said group, having previously withdrawn the cam-setting device; from its hexagonal socket and placing the said device within the said 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 camsetting device being also keyed upon the feathered shaft 11, turns with this shaft 11 socket, after 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 of using the hexagonal form for the external shape of the cam-setting device, any other regular form concentric with the shaft 11 may be used, providing said form has equal sides will be the variety of positions attainable when setting the grinding shoes. I have found it desirableto relatively arrange the' sections 17 and 18 around the annular recesses to attain various results in the dis-' integrated roduct. The design I have here shown and adopted in connection with the annular recesses gives freedom in uickly interchanging the said sections. he section marked 68 and shown in perspective in Fig. 10, being preferably woven of square wire, presents a rough concave surface to assist in disintegrating the materials within, at the same time allowin the finer particles to pass through an reach the hopper. In operation the material to be disintegrated 1s fed into the feed hopper 42 and finds its way between the grinding shoes 8 and the concave grinding surface 64, and is partially disintegrated, as it moves 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 car ried on to be reground on other grinding sections'ofs'aid cylindrical partition within the-annularrecess or are carried around and ground again and again, the finer particles of material finding their way through the open sections after'the'y are formed. I

Auxiliary grinding is accomplished by allowing some of the material to pass into I the trough 20 and'down into the adjoining grinding compartment 50, where the process I is carried on in a manner similar and with s1m1lar means to that ust described for the initial grinding cham or 49. The 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 to 50.

rests, and that when the disks are revolved the knife or heater is held a radial position by centrifugal force, and I disclaim said mechanical construction. My invention employs grinding shoes 8 'so mounted that their mass, when operated on by centrifugal.

force, impacts upon the material being ground or disintegrated with a degree of resiliency and so mounted that their mass can not be thrown into radial alinement with the axes of the supporting disks 5 the' weight of the shoes 8 is therefore thrown, by centrifugal force, not upontheir supports, but, u on the material constituting the work of t e machine, and therefore not upon the rod 7 or cam 10. In the machinesof the prior art referred to in this disclaimer, the knives or hammers cut, or break, or beat the material with their front faces,

vas they are revolved, held in radial position by centrifugal force with the weight of the cutting or beating tool entirely upon the rod or pin upon which it is pivotally mounted;

1n my present invention the shoe 8 is I dragged behind its. rod 7 with its rearwardly curved grinding face, roughened by the milled teeth 55, 55 or other suitable means, thrown outwardly by centrifugal force, working against the curved abrasive inner face of the inclosing cylindrical receptacle, formed of sections 17 and 18 as hereinbefore described. The material being disintegrated or ground is thus dragged by the shoe 8 against the-faces of the sections 17 and 18, and. at thesame time is subjected to the weight of the shoe 8 as the same is forced outwardly by centrifugal force, within the limit of movement defined for the shoe 8 by the adjustment of the cam 10. At the same time, the mounting of the shoe 8 is such that 'it will yield and be depressed by an infrangible obstruction, accidentally fed to the machine, such as aniron bolt, which would otherwise be likely to breakand destroy the shoe 8, or rupture the cylinder, and put the machine out of service.

, It will be understood that the foregoing description of the function and mode of operation of the shoes 8 applies to the ma chine when in operation upon material, and while the material is being properly fed to the machine by one skilled in the operating of-such machinery. If the disks 5 are re.-

volved without material being fed, the

weight of the shoe .is divided between the rod 7 and the cam 10, and this condition continues under the light feeding of material.
