EARTH-PULVERIZING MACHINE. j

To -a2 whom it may. c oncemf- Be 1t known that I, HANS CHRISTENSEN,

asubject o'f 'the King of Denmark, residing at Chicago, in the county of Cook and State oflllinois, have invented certain new and useful Improvements in an Earth-Pulver lzing Machine; and I do hereby declare the following to be a full, clear, and exact descrlption of the invention, such as will enable others skilled in the art to whichit a-ppertains to make and use the same,

This invention relates to an earth pulverizing machine, and the object is to provide in connection with a series, or a plurality of series, of rotatable disks,rotary devices associated with each series ofdisks and geared thereto, each of the devices "last named including an axial element and arms radiatingtherefrom.

further objectis to provide, inconnection with the construction above specified,

means for varying the angle: between the axialielements mounting the rotary disks.

fA still further object is, to provide, in a deviceof the typeindicated, a main frame including a" plurality of pairs of shaft mounting dev ices,with the shafts mounted therein, a series of disks carried by each shaft, and particular means forfvarying the angular relation of the shafts.

Astill further objects to provide, in the aboveconstruction, aplurality'of bars, connected respectively to the sections of the device mounting the series of disks, and 'connected with links operated directly by a worm wheel, the latter being controlled by a worm shaft constituting a part of the con trolling mechanism operated by'the driver of the machine. I v V With the foregoing and other objects in view, the invention consists in the novel construction, combination, and arrangement of elements hereinafter described and claimed, it being understood-that modificationsbrvariations in, details of construc-' tion may. be made, within the scope of the appended clair'ns- Inthe drawingsx. I p I Figure 1 is a top plan view, one of. the guard. plates .being removed, and the p votedframes being. at an angle with reference to each other." p I I ."Fig. 2 is a vertical section on the line 2-2 of Fig.- 1, howing the.. oontroll1ng mea s for one Of th p ed fra in Specification o1 Letterslatent.

vation, and showing the drive for the earth working elements of one pivoted frame.

F1g."3 shows one of'the pivoted frames in an elevated position, a portion of the main frame also being shown. 2

Fig. iis a view chiefly-in top plan, show.-

ing the operating and controlling elements for thepivoted frame, detached from the supporting structures I that is the] bars 16' and 17'is a block or draft element 18, and the rearends'of the barsare offset and connected by m'eansof bolts 19 with a downwardly turned flange o f.bar10..' v

- Extending rearwardly from eachjen'd of the bar 10 is a bracket 21 or 22 as the case may be, this bracket having connection with an element 23, on, each side of the machine, adapted to receive the central portion. of one of the shafts: mounting the disks 24.

thrown to a position in approximate alinement, and may be alsothrown out of alinement, so that they will assume various angu lar positions with reference to each other. The shafts 25 may be square in cross section, corresponding, openings. being provided in the central portions of the disks, so that the latter are non-rotatable on the shafts, but are rotatable with the shaft, each shaft carrying a' sprocket wheel 27 on its inner end, and a sprocket. wheel 28 on its'outer.

end, these Wheels and the smaller wheels 29 and 30 on shafts 31 being-rotatable together, in view of the drivethrough the. chains 32.

These shafts 31 may also be square incross section if desired, and they carry a plurality of. series of teeth, flattened asshown at 33, toward'the endportions which are thereby sharpened, and which. act in conjunction with the" disks, with which ey alternate,

Theshafts are designated 25, and may be erence to.those first referred to. The teeth project to a point between the outer edges of the disks and thecentral portions thereof,

in order to insure effective cooperation. The disks are spaced by tubular spacing elements 35. V

In "order to make suitable provision for the mounting of the shafts, and for the control of the two main sections of the appavratus, I provide a frame for each section,

theframe including an upper transverse ele ment 36,. an outer frame, element 37. con nected therewith, and an inner frame element 38, the devices 37 and 38 each being provided with bearings for the mounting of shafts and 31. A guard plate, formed as shown, is provided for each section of the machine and is connected with each upper transverse element 36. Chains 40 and 41 are connected respectively with the guard memberS,- and are adapted to engage the books or pins 42 on element 10, this arrangement permitting of the raising of the rear portion of each frame, and therefore ofthe elevationvof the shaft 31 to a given extent with reference to shaft 25. I

Pivotally connected with each frame is a bar 44having an offset portion l5 and extending forwardly to a point where it has pivotal'connection with a link 46, extending in a vertical direction and movable angularly with reference to a transverse pin 48 passing through bracket members 49. 'A worm wheel 50 is mounted on this pin,iand the links or arms just referred to are rigid with reference to the worm wheel, so that the links are shifted upon the rotation of that wheel through any given angle.

- A worm 51 cooperates with the worm wheel and is mounted on a vertical shaft 52 carrying a wheel 53, within convenient reach of thedriver. A bracket 54 may be formed as shown and includes a centralportion apertured for'the accommodation of the verti cal shaft mounting the worm. The respective sections ofthe "machine are vmovable about the pivotal point upon the rotation of the worm and. worm wheel, in view of the movement imparted to the bars connected :with the respective frames, and'the angular relation of the shafts carrying the. disks may therefore be varied, and the shafts 31 re maining parallel with similarly controlled;

In order to permit of the swinging of the the shafts 25,. will be pivoted section orframes about afhorizontal axis, I connect each frame with one of the bars 44; by. employing a bracket 56 mounted on the inner end of the pivoted"franie, the bar being pivoted to the bracket. The outer main frame, frames pivotally connected with each end of the main framef'a plurality of shafts mounted in each pivoted frame, means for imparting movement from one sha tto the adjacent shaft-in the same frame, earth working fdevices mounted on said'shafts, and means for changing the rel .ative position of thepivoted frames.
