GROUND-PULVERIZER.

specification of Letters Patent.

Patented Apr. 18, 1916.

Application filed neeember 6. 1915. Serial No. 65,223.

7 '0 all whom it may concern Be it known that I, HENRY Anions, a citi W zen of the United States, and resident of Brillion, in the county of Calumet and State of Visconsin, have invented certain new and useful Improvements in Ground Pulverizers; and I do hereby declare that the following is a full, clear, and exact description thereof;

This invention relates to new and useful improvements in soil working apparatus and is more particularly directedto the provision of a pulverizer including a plurality of ground engaging cylinders.

It is primarily the object of the present invention to provide such a structure wherein the load of the frame and of the operator is distributed in such manner as to procure an exceedingly ellicient operation.

It is further an object to provide in a pulverizer, wherein one of the rollers is of a toothed type, means whereby the load of said roller is imparted thereto in a resilient. manner to protect it from damage or pos sible breakage due to engagement with stones or the like.

With the above and other objects and advantages in view, the invention resides more particularly in the novel combination, ar rangement and formation of parts more particularly hereinafter described-and particularly pointed out in the appended claims.

In the drawings: Figure l is a side eleva tion of a pulverizer constructed in accord-- ance with the present invention. Fig. 2 is a top plan view thereof with portions broken away to more clearly disclose the structure. Fig. 3 is a detail sectional view taken through'the pivotal connection of the roller on the line 3 3 of Fig. 1.

Referring now more particularly to the accompanying drawings, there is provided a body frame including end castings '5 each in the form of a triangular frame. one of the sides of which is disposed horizontally to form the top of the casting, and is provided at its ends with inwardly extending flange portions 6, which flange portions are continued at the adjacent ends of the othor-siihes of the frame to form means for securing respective ends of angle bars 7 which connect the castings. At the meeting ends of the head 8 which carries a bearing sleeve!) in which is journaled the shaft 10 of the for ward roller 11. this roller comprising aseries of disk members having their peripheries angular in cross-section and having their sides abutting to form substantially a cylinder provided with a spaced series of annular ribs. This general structure is disclosed in Patent No 795327, granted July 1905 \s in this previous patent a draft tongue 12 is disposed transversely of and secured to the angle bars 7 I secured to the fin-ward angle bar and to a plate 14 carried by the tongue forwardly of the. frame. For pivotally mounting the rear toothed roller 15, a pair of angular bars 16, are provided which include relatively and braces 13 are short arm sections enlarged to carry at their free end portions, sleeves 17 jom'nalingthe forward sides of the castings, the curvaturefl ot each rib having the pivot of the arm as a] rad i us. casting head R are pro ided with hooks 21' hav ng their bills extending in opposite directions and :ely strong retractlle z zi, |,,i. 1 ,p l g s is i taco pan o 00 (s.

The drn s 23 is carried by a bar 24 which extends from the rear of the draft tongue, this bar being braccdby a link 25.

Each bar 16 and the respective;

intern'iediatcly secured thereto by the clamp plates 25' and secured at its forward apertured end by engagement with the bight of a J-bolt 26, this J-bolt also'carrying a link 27 whichhas its forward end upwardly offset and carrying the double-tree pin 2.8. The rear roller 15 con'iprises a plurality of toothed disks 29 carried on huh-members 3i) and held spaced thereby so thatsaid disks are disposed at the side edges ofthe disks of the forward rollers whereby they engage the ridges of ground formed by the forward j rollers.

By the structure above described, it seen that the entire weight of the body frame and of the draft tongueand of the driver is imparted to the forward roller ll, and that apdesired portion of this weight is indirectly imparted to the rear roller 15 through the medium of the springs 22. As

the forward roller performs the most work it consequently carries the greater load. By positioning the toothed roller 15 rearwardly of the ribbed roller 11, it is noted that any clogs or other hard lumps which are not pressed by the roller 11 will be however, dis posed by said rolier directly' in the path of a respective disk of the roller 15 so that the teeth or" said disk may act thereon to u'eak it up. i

The roller 1 having its load resiliently imparted thereto may ride orer stones without damage or danger of possible breakage to its tooth. As the forward ends of the bars 16 are engagimblc with the ribs 20 throughout the possible morements. it is seen that the pivots of said bars are thereby relieved from strain due to lateral impulses imparted to the rear roller structure.

I claim:

1. A pulverizer comprising a seat and tongue carrying bod frame, a roller carried by the frame. bars pivoted to the frame and extending rearwardly thereof with their rear ends directed downwardly, a second roller carried by the said do .\'nwardly direc-ted ends oi the bars and retractile springs connecting" said bars and the frame.

2. A pulverizer comprising a body frame, including pairs of depending end members, a roller carried by said members. corresponding members of each pair having poi tions offset, angular bars each having one arm inte'rmediately pivoted in a respective offset and extended adjacent the other respective depending member, a roller carried by the other arms of the bars and springs connecting; said bars and the frame.

3. A pulverizer comprising a seat and tongue imrrying body frame, a cylindrical 40 roller carried thereby, a series of annular ribs on the rol er, a toothed ground engaging member pivotally carried by the frame rearwardl o the roller and having its teeth arranged in lonr'tudinal alinement with the lrasc portions of the ribs, and means resiliently urging the said toothed member to the ground. I

In testimony that I claim the for going I have hereunto set my hand at Bril ion, in the count of Calumet and State of Wisconsin, in the presence of two Witnesses.
