COMBINED HARROW, CLOD-CRUSHER, AND LAND-ROLLER SPECIFICATION formig g part of Letters Patent No. 376,841, dated January 24, 18 88. Application filed August 18, 1887. Serial No. 247,252. (hlo model.) l v To aIZZ whom it may concern:

Be it known that I, GEORGE W. ALBAUGH, a citizen of the United States, and a resident of State Line,in the county of Franklin and State oI' Pennsylvania, have invented certain new and useful Improvementsin a Combined Harrow, Clod-Orusher and Land-Roller; and Ido hereby declare that the following -is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figurel is a side view of myimproved combined harrow, clod-crusher, and land-roller. Fig. 2 is a longitudinal vertical sectional view of the same. Fig. 3 is a transverse vertical sectional view takenon line we in Fig. 1. Fig. 4 is a top plan view; and Fig. 5 is a detail perspective view of one of the brackets and one of the wheels or rollers of the pivoted frame. Likeletters of reference denote corresponding parts in all the figures. r

My invention has relation'to that class of inventions known as combined harrows, clodcrushers, and land-rollers, and it consists in the construction and combination of parts of the same, as will be hereinafter more fully described and claimed.

In the accompanying drawings, the letter A platform, D, secured thereto. BracketsE EE project downwardly from the rear end of the main frame, and are formed with bearings at their lower ends to receive the trunnions of two land-rollers, F F. V

A transverse frame, G, is pivoted upon a king-bolt, G, under the forward end of the main frame, and has brackets 'H H H, similar to those secured to the rear end ofthe main frame, projecting downwardly. The trunnions I I of the clod-crushers IIarejournaled in the lower ends of these brackets,to the outer ones of which are secured outwardly-projecting screw-threaded bolts J J, to which two longitudinally-slotted bars KK are adj ustably secured by means of thumb-nuts L L. The

the slots in the bars and serve to keep the said bars in a vertical position. To the lower ends of these slotted bars, which are provided with stub-axles M M, are j-ournaled wheels or rollers N N, adapted'to travel upon the ground.

Two or moreharrow-beams, R R, hingedtogether at their sides and having teeth, preferably inclinedrearwardly in their under'sides, are attached to the hooksQ Q upon the rear side of the doubletree Q by means of chains rear one of these barrow-beams has a chain, T,

. 5 b 1; denote the markers, having curved flattened lower ends, and are secured in the bars It will be seenthat by having theadjustable bars, with wheels journaled thereto,the crusher-rollers may be raised or'lowered according] to the condition of the ground, andwhen the implement is transported from one placeto another the wheels orrollers are lowered sufficiently to allow the pressure-rollers to pass over the ground without coming in contact with the same.

It will further be seen that by havlng the harrow supported'by the chains connected to v the doubletree and to the lever the harrow mayrock to either side, and will follow any unevenness of the ground,or, if desired,it may be raised from contact with the ground by means of the operating-lever.

The implement will first harrow the ground, whereupon the crusher-rollers will crush any clods which were not broken by the harrow, and at last the land-rollers will smooth the ground,leaving it perfectlyprepared for planting. All of these processes will be performed at once without requiring but little more draft than either one of the separate elements.

Having thus described myinvention,I claim and desire to secure by'Letters Patent of the United States 1. In a combined harrow, clodcrusher, and land-roller, the combination of the main frame having brackets in its rear end, land-rollers journaled therein,a pivoted cross-fran1e at its forward end, brackets secured thereto, and clod-crushers journaled in said brackets, with slotted bars formed at their lower ends with stub-axles, wheels, orrollers journaled upon said axles, and means, substantially as described, for adjusting said bars.

2. In a combined harrow, clod-erusher, and landroller, the combination of the main frame having brackets secured in its rear end, landrollers journaled in said brackets,brackets secured at its forward end, screw-threaded bolts projecting outwardly therefrom, and cloderushers journaled in said brackets, wlth slotted bars formed at their lower ends with stubaxles, wheels, or rollers journaled theret0,and thumb-nuts.

3. In a combined harrow, clod-crusher,and land-roller, the combination of the main frame,

land-rollers journaled in its rear end, a cross frame pivoted to its forward end, clod-crushers journaled in brackets secured to the said cross-frame, and markers, substantially as described,secured to the side of the mainframe, with aharrow consisting of two or more beams having teeth in their under sides hinged together, the tongue secured to said cross-frame, a doubletree secured to said tongue, chains connecting said harrow with said doubletree, and means,substantially as described,for raising and lowering the said harrow.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

GEORGE W. ALBAUGH.
