LGRINDlNc R CRUSHING MACHINE.
SPECIFICATION forming part of Letters Patent N o. 533,018, dated'J'anuary 22, 1 895.
Application tiled November 2, 1893. Serial No. 489,782. (No model.)
.To a/Z whom it may concern:
Be 1t known that I, JEROME PRINCE, of Milford, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Grinding or Crushing Machines, of which the following, taken in connection with the accompanying drawings, is a specification. A
My invention embodies various improve? ments 1n grinding and crushing machines, especially valuable 1n grinding bones, shells,
and the like for fertilizers, or in crushing beets for sugar making.
A prominent feature of my invention is the horizontally arranged, tapering, male and female grinders between which the material to be crushed passes, discharging at either end.
l The outer or hollow female grinder has a tamale, inner roller has one bearing in the in.
V terior partition of the frame and the other, at
the extremity of its prolonged stem, -in a peculiar bracket fixed on the outer wall of lthe case. There are preferably two or more pairs of these grinders arranged end to end in the case, and fixed on the Same continuous shaft, so that the end-wise thrust of one male grinder neutralizes that of the other. lThe gearing is so arranged that each inner grinder turns in the opposite direction from its female mate. A hopper common to all the grinders is provided, with a spout leading to it, and a slide controlling the feed of material to each pair. The hopper may be partitioned centrally, to provide for grinding different material on opposite sides.
In the drawings Figure l represents avertical section of my improved machine on line of Fig. 2. Fig. 2 represents a horizontal section of the case and intermediate partitions on line y-y of Fig. l. Fig. 3 represents a front elevation of the gearing.
A is the frame (Lf the machine upon which is mounted the case B. Disposed in the case B are one or more pairs of grinders, six pairs being shown in Fig. 2. The outer grinder C is mounted in bearings at c and has a conical opening through `its length, the Surface of said opening being broken by projections or corrugations C. An enlarged tubular ljourgal O2 forms part of each grinder C as in ig. l.
GrinderC partiallyinclosesa conical inside grinder D whose outer surface is preferably at an angle slightly more acute than the tapering inner walls of said grinder O. The surface of the male grinder D also has corrugations or projections d. Each shaft dupon which the grinders D are mounted passes entirely-through and projects from each side of it a gear d2.
Grinders C have mounted on their tubular journals connecting gears G.
On one end of the case B is mounted a shaft g, bearing on it gear g meshing with the gear cl2. Bracket H supports above shaft g a second shaft h, which carries on one end the gear h meshing with gear g', and another gear h2 which meshes with one of the outer guide gears G. Shaft hcarries gear h3 which connects with the rear train of gearing on the outer grinder C. Slides J regulate the amount of material fed to the grinders, each compartment having an independent slide.
K is the hopper and M the supply pipe from the large bin.
N is the receiver for the lower outlets, and O, O are the receivers for the side outlets.
If the gears G and e are of the diameters shown as compared with their respective grinders, and in mesh as represented, the middle set of grinders will turn in the opposite direction from vthose at either side. To cause all the male grinders to turn in one `direction and all the female to turn the other ICO way, it is only necessary to reducethe diame-4 ter of their respective gears and introduce pinions between them.
The operation of the machine is as follows: The material to be ground is contained in the hopper K and is supplied to the different compartments by withdrawing the slides J. Power applied to pulley f, is transmitted through the shaft CZ to the series of inner grinders D, by means of the gears e, which revolve them in the direction shown by the arrows. Power is transmitted to the outer or female grinders C. by means of the gear d2 on the end of shaft d', and through the gears g', h and 72,2 to the end gears G, on the front side, and by gear h3 on the rear. The extra gear h is used to reverse the motion of the outer grinder C from that of the inner grinders D, as shown by the arrows. The larger end of each grinder D protrudes beyond lthe open end of the hollow grinder C, so that the bones or other materials to be ground rest upon its upper surface. At each side of these protruding ends, and in the horizontal plane of their axes is a solid ledge L, formed on or secured to the partition E, as seen in Fig. 2. These ledges prevent the bones, rbc., from passing down bodily at the ends of the rollers C and at each side of the protruding ends D, and oblige the material to work into the annular space between these rollers, there to become disintegrated. These rollers revolve in opposite directions, the grinding surface of each moving upwardly toward the line where the bones' enter from above. A portion of the crushed material will naturally work toward the small end of the rollers D, to escape the pressure of the mass in the hopper, and. other portions will escape at the large end, as indicated in Fig. l. The centrifugal See Fig. 1.
Diiferent grades of work are turned out by giving more or less space between the grinders.
I claim as my invention 1. In a grinding or crushing machine, the tapered grinders C, D, working one within the other, with an annular space between tliein, the body of the inner grinder D extending at its larger end beyond the extremity of the outer one `and having an axial journal and bearing, and the outer grinder having at its opposite end a hollow journal surroundin g theprolonged stem of the inner one, in combination with the wall or partition E'and the solid ledges L thereon, at each side of the protruding larger end of the grinder D, substantially as set forth.
2. In a grinding or` frame having a plurality of compartments, horizontally disposed i male' and female toothed grinders Workingtherein, gearing arranged to turn such grinders in opposite directions, a hopper common to all the compartments and a separate slide for each, in com bination with discharge openings-at both ends of the grinders, substantially as set forth.
3. In a grinding or crushing machine, two inside conical grinders D D lxed on the same continuous shaft d', with their bases toward each other, so as `to neutralize the endwise thrust in combination with two internally tapering female grinders C surrounding such inside grinders and formed with hollow axial extensions c2 constituting their journals, and with gearing applied to such projectingjournals and to a connecting shaft, substantially as set forth. A
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this l9tl1 day of October, A. D. l893.
