IMPRovEMENT IN cLoD-BREARBR ANDPULvERlzE/R,

The Schedule referred in these Letters Patent anctmaking part of the same.

"ing part ot' this specification.

The object of my invention is to provide a means for thoroughly pulverizing all lumps and clods of earth which may remain after ground has been plowed and hart-owed in the common manner, to prepare it, by.r

the useof animal-power, for the reception of seeds ordinarily cultivated by hand, aswell as to furnish a convenient clod-breaker for general farm-work.

1n the accompanying drawings- Figure l is a longitudinal vertical section, taken in the line :t: xof Fig. 1I.. Figure' 1I is a plan or top view of the machine.

Like letters designate like parts in each of the iigm-es.A

The three chains, composed of links, e e c, are coupled together at their forward ends by the ring f, which furnishes a convenient means of attaching the motive-power to the machine.

Through a link of each chain, at a proper distance from the riuoto secure the easiest draught- I )ass v E 7 A D 7 the square bar opening the links e e e first for that purpose, and spreadingthe outer chains, so that they shall be at equal distances from either end of said bar, and' from the centre chain, which last is made to correspond with the centre ot' the bar B.

The links e e e, through which the bar B passes, are then closed down upon notches in lthe same, or are held by bolts or pin permanently in position thereon, and are so adj usted that when the chainslie along the ground, an edge or angle of the bar Bshall be downwards, and so that a horizontal line shall pass through two angles thereof, not contiguous'if a square bar, or contiguous if a triangular bar, as I do -not contine myself to the use of square bars, a triangular bar answering equally as well.

Twoor more links back of this bal' B,'in each of the chains, and through corresponding links therein, I pass the second bar Bi, and fasten it in like manner and position astlic iirst, and so-.ou with bars B" and lil, all ot' the bars being at equal ,distances from each other, and their number being increased-according to the power designed to draw the machine, or the amount ot work required of it. y

The number ot' chains may also be increased, it

needed to secure strength; and I do not contiue inyselt to any specilie number or sizes o l' chains or bars.

Upon the bars B to B', and between their chains, I' place, so as to rest loosely upon the same, the bearers A A, of such a length as to reach over all the bars,

and which are united at their ends by the tiesc c, and further united by the 'ends a a and bottom b ot' the box E, which is formed by the last-mentioned pieces, and a part of the bearers A A serving as sides therefor.

the bars and chains by loopsat d cl, which attach the ties c c to the links e e of the central chain.

The brward ends of the bearers are turned up like the runners of a sled, and for a like purpose.

The uses and operationvof my machine are as follows:

Having placed a suicient weight ,in the box E to give the crushing weight required, the machine is drawn forward by the ring j, an angle ot' each of the bars l5l to B resting upon the ground, and, as then, successively come in contact with the clods or lumps of earth uponthe surface, and heilig' held to their work bythe load inthe box E operating eifectually upon each bar by means of the bearers A A, and yet allowing free motion upon lifting the load both' laterally land vertically, by reason of the link-connections, they aire cut, crushed, or ground bythe sharp angles of the bars, the weight of the load, or the wave-like motion secured tothe barsby their link-connections, said links also assisting in the disintegration of the lumps, the whole thus securing the pulveri'zing ot' each clod or lump over which the machine passes.

Other advantages secured by my invention are the slight liability to clog, secured by the link-connections ofthe bars, andthe tendency 'oi' the machine when in operation to level as well as pulverize the ground.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The use ot' parallel chains, attached. atk right angles, or angles less than right angles, to parallel bars, the whole forming a drag for the purpose of destroying clods or lumps ot' earth, by attrition, when drawn over the same.

2. The use of angular bars of metal, secured so as `to be drawn over the ground with an edge or angle downward, and in Contact therewith, for pulverizing the surface of the ground, as aud for the purposes hereinbefore described..

3. Unit-ing the bars B to B'i by links, soasto allow 4. The angular bars Bto B, box E, and bearers A, chains e e e, and. loops cl l1, all arranged and combined substantially as and for the purposes hereinbefore described. g
