Opinion

SAGE. District Judge.

This is a suit on two patents, owned by complainant,—No. 344,950, issued July 6,1886, to Basil C. Dorsey, for an improvement in disk seeders and cultivators; and No. 418,199, issued December 31, 1889, to P. E. Little, for an improvement in harrows. The Dorsey patent relates to a construction of disk harrows wherein two gangs of disks are pivoted to the main beam, one in advance of the other, and one gang arranged to overlap the other. The Little patent relates to a particular construction of hinge for coupling the gangs of disks to the main frame of the harrow. The only claim alleged to be infringed in the Dorsey patent is the first, which reads as follows:

“The disk gangs, G, the disks or cutters of Avhich are cupped or concaved outwardly to throw' the dirt from the center, said gangs having their inner or adjacent ends overlapping, with the innermost cutter or disk of one working between the innermost two of the other, substantially as herein deucnbeu.--

[732]*732The defenses are (1) noninfringement; (2) lack of novelty, if the claim is to be broadly construed. Counsel for defendant call attention to diagram in Fig. '3 of the letters patent, to which the patentee in his specification refers as “a diagram showing the overlapping-feature of the disk gangs,” and contends that the two gangs of disks, as shown in the diagram, in addition to merely overlapping, bear a peculiar relation to, each other, in that the innermost cutter of one gang is located bodily between the innermost two cutters of the other gang. He also calls attention to his claim that the construction of the harrow shown is such that no change of angle of the gangs to the line of draft can alter this peculiar relation of the innermost disks, which determines the place of the one actually and bodily between the other two.

The Horsey patent is for an improvement in “disk seeders and cultivators.” The invention consists of a frame upon the underside of which are adjustably secured at an angle to each other two shafts carrying disks. These disks are concaved or cupped outwardly, and held in position by intervening spool-like castings surroundingthe shaft, the whole construction being called a “disk gang.” These gangs are so placed that they overlap at their inner ends, the innermost disk of one gang tracking .between the innermost two of the other. In operation, as the machine is drawn across a field, the disks enter the soil, and, partly sliding therein, turn it over, and thoroughly pulverize it, their convex faces, inclined to the path of travel, tending to raise and throw from them in a shower the earth they encounter. This is claimed to be a great improvement—First, over the old method of cultivating by first plowing and then har-rowing the soil; ^second, over all previous methods of using rolling disks to cut and pulverize it. Many devices have been invented and patented for accomplishing this result by the use of rolling disks. Among the first was to use disks dished or saucer-shaped. The [733]*733next step was to provide two shafts and sets of wheels or gangs, placed at an angle to each other, the tendency of one gang to make . the machine go in one direction being counteracted by the tendency of the other in the opposite direction, so that the machine could be drawn straight across the field. Sometimes one gang was set in front of the other, but generally they were placed abreast., and so connected with the frame as to yield to the inequalities in the surface of the ground. But then, if the disks were cupped outwardly, there would be a strip of unfilled land between the two gangs, and, if they were cupped inwardly, a ridge would be thrown up between them, which could not be leveled by the next passage of the machine without lapping more than half its width, and doing more than one-half its work the second time. The next improvement was to make the frames carrying the disk-gangs overlap a little, hut this did not remove the difficulty. It only resulted in making the ridge narrower. Then—and this was as early as 1876—it was attempted to remedy this defect by abandoning tbe end to end arrangement of the gangs, and placing them tandem instead of abreast. The result was to reduce by one-half' the width of the strip harrowed, without reducing appreciably the draft of the machine; so that arrangement was abandoned, and tbe gangs continued to be constructed abreast, with their disks cupped towards the center, which involved the objectionable ridge in tbe middle.

If is claimed that no remedy that was not fatal to the practical success of the machine was provided by any of the numerous inventors working in the art until Dorsey, by his patented machine, presented a simple and effective one. lie, it is claimed, discovered that by placing the gangs at proper counterbalancing angles and approximately abreast, so as to work over an area as wide as their aggregate space, but with one gang slightly ahead of tbe other, and the ends overlapping just enough to enable the innermost disk of one gang to do its work between the innermost two disks of the other, the ground would be equally and evenly tilled, without leaving' any ridge or uncultivated strip. The invention is described in ihe specification as follows:

“The disks are concaved or cupped outwardly, so that they throw the dirt from the center. The inner or adjacent ends of the disk gangs, it will he specially observed, overlap; the end disk of one gang operating between file end two of the other gang-. This is an important feature of my Invention, as it effects a result which, so far as I am aware, lias never heen done by a disk cultivator. Generally, the disk gangs abut as near as possible, if the disks are cupped outwardly, the innermost of each gang, throwing from the center, leaves a strip of uncultivated ground, while, if they are cupped inwardly, they throw up a ridge in the center, by reason of not being adapted, on account of their shape, to he brought close together; hut by overlapping them, as I have shown, and cupping thorn outwardly, neither of these results follows, but the center is cultivated equally with the sides.”

The court is of opinion that upon the record the complainant's device is novel and useful, and that it is patentable. That it is patentable seems to be conceded on behalf of the defense, which rests upon the proposition that the claim is not to be broadly construed, and is good only for the particular construction described and claimed; that is to say, to cover only a harrow showing two gangs of disks, not merely overlapping, but so adjusted that the innermost [734]*734cutter of one gang is located bodily between the innermost two cutters of the other gang. It is claimed for the defendant that the alleged infringing harrowT is not of this particular construction; that, while the disk gangs overlap, so that in operation the cut or track of the innermost disk of one gang is between the cuts and tracks of the innermost two disks of the other gang, the- innermost disk of one gang is not located between the innermost two disks of the other gang.

The defendant’s machine is provided with two diagonally arranged disk gangs, the disks being cupped or concaved outwardly to throw the dirt from center. The inner ends of the gangs overlap. The innermost disks of the rear gang work between the innermost two of the other gang.
