CLOD-CRUSHER.

SPECIFICATION forming part of Letters Patent No. 465,356, dated January 5, 1 892.\ Application led December 11, 1890. Serial No. 374,274. (No model.)

To all whom t may concern,.-

Be it'known that I, FREDERICK MEIER, a

citizen of the United States, residing'at Battle Creek, in the county of Calhoun and State of Michigan,

have invented certain Vnew and useful Improvements inLand Lump and Olody Crushers, of which the following is a specifi' cation, reference being had to the accom panying drawings, forming part thereof.V

The object of this invention and vmode of vits operation will bereadily discovered by; those skilled in land cultivation by a'mere 'inspection of the drawings.

that, among its objects are the following: fi rst, to out the hard clods and lumps of baked soil to pieces instead of simply crushing the same, as heretofore attempted, by the mere weight of the implement; second, to let the severed parts pass between the cutter-bars to the'interior of the roller-cylinder, where theyare alternately lifted and let fall from bottom to top, and vice versa, of the rollerlby means of centrally converging clods are Carried and thoroughly pulverized, as is evident.

In the drawings, Figure l represents a front View of my novel invention having the tonguev .the roller-heads with all the bars in place.

Fig.- 4 represents the completed implement in perspective elevation,mounted and ready for Fig. 5 is a longitudinal section through one of the roller-heads, show ing one construction by which the bars-may be removed independently the one of the other; and Figs' and 7 are respectively an inner face View and an outer face View of the roller-head, and shows another construction adapted to permit independent removability of the bars. l l l Referring now particular] y to the letters and numerals of reference designating different portions of the drawings, wherein similar letters and iigures referto the same parts in all the views. y A is a platforminclosedby anupwardly-projecting border A', which forms a con ven- Further than plates suitably prov vided therein, whereby the severed lumpsandY stones or other obstructions from the field,

'and also kfor use in weighting the implement -according to the ever-varying conditions of soil, dac'. Depending vertically from the extreme ends of theplatforln or from its border A are the roller-supports and bearings 1 l, andcentr'ally between the saine depends a similar support?, and from the said platform (or the tongue) rises the usual support for the drivers seat a, and diagonal lateral braces c c attach at their rear ends to the platform, and at their forward ends are firmly fixed to the tongue T, and asimilar brace (l reaches from the under side of said tongue to the'central vertical support 2, as seen in Figs. 1,2, and 4. B is the roller-shaft, which may be made in two parts, so that the rollers, of which two are 'preferably used, revolve independently, or the said shaft may be continuous throughout, as maybe preferred.

- C represents the roller-head, provided on its inner annular face with anges l), b', and Z1,

6oL I arranged V in series, as shown, said flanges b and b inclining toward each other, thus forming receptacles in shape similar to a truncated cone, the'base of eachbeing formed by the fiange b and the sides by the flanges b and bto receive the ends of the bars D, which areV triangular or V-shaped in cross-section, and are secured tothe heads by means of setscrews S engaging with suitable countersinks or holes in the base of said bars. The bars are removable independently the'one of the other without removing or displacing the roller-heads. Many constructions to permit of such removability of the bars will readily suggest themselves to those skilled in the art towhich this invention appertains, and I therefore do not wish to be understood as limitinginyself to any particular construction for the purpose. Two examples are shown in the drawings.

In Fig. 5 the bars are shown as made somewhat shorter than the space between the heads, so that they will have an endwise movement between said heads when the bolts holding them are loosened of a little more than the amount of projection inward of a liange,

so that by simply loosening the bolts holding a bar and moving said bar until one'end is in Contact with the inner surface of a head the IOO opposite end is free to drop down out of engagement with the flange, when the bar cank be removed.

In the construction shown in Figs. (i and 7 the heads are or may be solid and the ends of the bars reach through the same to the ontermostfaces thereof. With this construction by simply turning back the set-screws at either end or head the bar will be permitted to slide in its V-shaped horizontal channel, so as to allow of its removal. Plates P are provided reaching from the base of two or more of the cutter-bars D, say, about one-half way therefrom toward the central shaft, the office of which is to alternately lift and let fall the hard lumps of soil that pass between the cutter-bars to the inside of the roller. These plates may be attached to the heads or to the base of said bars, or to both, so that they be firmly fixed and run longitudinally of said roller, whereby a much more perfect pulverization and commutation of the soilis secured than by any means heretofore employed, as is evident. I prefer to have the openings between the cutter-bars aggregate about one-quarteror one-third. the entire periphery of the roller at the base of said bars, though this is a matter of no great moment, provided considerable openings are provided between each of the longitudinal bars for the entrance of the severed lumps and exit of the pnlverized soil.

Having thus fully described and illustrated my invention, and pointed ont its more distingnishing features and novel mode of operation, what I claim, and desire to secure by Letters Patent of the United States, is-

1. In a land-roller, the periphery thereof, formed of cutter-bars and open spaces between the same communicating with the interor of the roller, said bars having holes or countersinks in their bases, and set-screws engaging said holes or conntersinks for re movably securing the bars in place, substantially as described. I

2. In a land-roller, the roller-heads, in combination with independently-removable cutter-bars and set-screws engaging said cutterbars and serving to hold the same rigidly in the place described.

3. In a land-roller, the periphery thereof, consisting of alternate longitudinal cutterbars and open spaces between the same communicating with the interior of said roller, in combination with longitudinal plates within the roller, all substantially as described, and for the purpose specified.

4. In a land-roller, the periphery thereof, formed of cutter-bars and open spaces between the same, said cutter-bars having broad bases or rear ends and tapered therefrom to a point and formed in their rear ends with t holes or conntersinks, in combination with set-screws engaging said holes or conntersinks and securing said cutter-bars rigidly in place, but permitting their removal, as speciiied.

5. In a land-roller, the periphery thereof, consisting of alternate longitudinal cutterbars and spaces between the same communieating with the interior of said roller, longitudinal plates reaching the length of said bars and depending therefrom, but about half the distance from the base of said bars to the roller-shaft, and set-screws s, and flanges b b b, arranged in series, as shown, for the purposes set forth.

In testimony whereof I hereunto affix my hand and signature, this 31st day of October, A. D. 1890, in the presence of two attesting witnesses.

FREDK. MEIER.
