Opinion

THAYER, Circuit Judge,

after stating the case as above, delivered the opinion of the court.

The first question to be considered on this appeal is whether the original patent, No. 175,588, granted to Roscoe Bean on April 4, 1876, was broadened by the reissued patent, No. 8,681, so as to bring within the claims of the latter patent a class or kind of pumps, that were not covered by the original patent. This question was answered by the circuit court in the affirmative.' 68 Fed. [819]*819213. The trial court held, in substance, that the original patent could not be classed as a pioneer patent, and that, in view of the explicit, language describing the invention found in the original specification, claims 1 and 2 of the original patent should be limited to a pump such as is shown in Fig. 1 of the foregoing statement, in which the tubular pipes, O and D (the former being an air chamber closed at its upper end, and the latter a discharge pipe), open into the cylinder or barrel of the pump, B, “on opposite sides thereof, and in the same horizontal plane,” thereby forming a substantial support for the cylinder. The trial court further held, in substance, that the original patent had been expanded in the reissue, because it appeared that the specification had been so altered in the reissue as to bring within the grasp of the reissued patent a class of pumps like that shown in Fig. 3 of the foregoing statement, in which the tubular pipes, O and D (the one being an air chamber and the other a discharge pipe), do not open into, and are not directly attached to, the cylinder, B, on opposite sides thereof, but are attached to, and open into, a chamber, F, located at any convenient distance above the cylinder, B, and below the platform of the well or cistern. We think that no error was committed by the circuit court in holding that the original patent issued to Roscoe Bean does not fa,ll within the category of pioneer inventions. The patentee made an improvement in an old device or old machine for elevating water, by changing to some extent the relation of its parts or elements, all of which were individually old; but he neither produced a distinctively uew and useful result, nor laid the foundation of a new art, nor applied one of the known or theretofore unknown forces of nature to a new and beneficial use. Suction pumps were certainly well known and in common use when Bean entered the field as an inventor, and air chambers, in one form or another, had long been used in connection with such pumps, to increase their efficiency. The pump invented by Bean operated upon the same principle and in the same way as other suction pumps then in use. It raised no more water, and obviously required no less force to actuate it. It is also apparent that the supporting air chamber employed by Bean, consisting of the elongated pipe, 0, in Fig. 1, though different in form and location from those in use on older structures, nevertheless operated upon the same principle. As the circuit court well remarked, Ihq novelty of the invention consists in making one pipe serve the double purpose of an air chamber and a support for the cylinder, when the cylinder, to prevent freezing, is placed some distance below the platform on which the pump stock is located. .But this feature of the device was not such a wide departure from the known mode of constructing suction puinps as to justify the application of new rules of interpretation. The patent is entitled to a fair and reasonable construction, but no greater latitude of construction can be allowed on the theory that it is a pioneer invention.

There are some expressions found in the specification of Bean’s original patent which render it certain that at the date of (he patent the method of constructing a pump indicated by the drawings at[820]*820tached to the patent (Figs. 2 and 8), in which the descending air and discharge pipes are attached directly to the cylinder, on opposite .sides thereof, and open into it, and thereby form a firm support for the cylinder, was the only method of constructing a pump and applying his invention which the patentee had at that time conceived or contemplated. Thus, in the second paragraph of the specification the patentee says:

“Tbe nature of my invention consists in the construction and novel arrangement of a pump stock, connected with the cylinder by two tubes, one forming an air chamber and the other the discharge pipe; said tubes opening into the cylinder directly opposite each otha‘, as will be hereinafter more fully set forth.”

And again, in describing the mode of construction and the advantages thereof, the inventor says:

“B is the pump cylinder connected to the pump, A, by means of two tubes, C and D. The lower ends of these tubes are screwed into pieces, a, a, between which the cylinder, B, is placed, and the parts then firmly bolted together. The pieces or elbows, a, a, open into the cylinder on opposite sides thereof, and in the same horizontal plane. * * * By this mode of connecting the pump stock and cylinder a substantial support is formed for the cylinder, and it is very simple and readily put together. * * * By having two holes in the cylinder (one for discharge and one for the air chamber), it gives a place for the air chamber to have a direct action on the water while in use; giving it an even, steady stream, and a direct discharge for.the water, independent of the air chamber.”

The claims of tbe original patent were well conceived and expressed to cover tbe method of construction and features of novelty thus clearly described. The original specification contained no intimation that the method of constructing a pump described in the specification and drawings was merely a preferable mode of construction, and that the depending air pipe and discharge pipe might with equal efficiency be attached to a chamber located at any convenient distance above the cylinder, instead of being fastened to the cylinder itself. From the fact that the latter mode of construction was not suggested in the original specification, it is evident that that method of constructing a pump had not been conceived by the patentee. Moreover, as no method of applying the invention was pointed out, except that which was explicitly described in the specification and drawings, an ordinary person, not versed in patent law, would naturally conclude that claims 1 and 2 of the original patent were limited to a combination of parts in which the air pipe, 0, and the discharge pipe, D, were attached to the cylinder on opposite sides, and opened into it.

But, aside from these considerations, the evidence in the record clearly shows that between the dates of Bean’s original and reissued letters patent (that is to say, between April 4, 1876, and March 25, 1879) a class of pumps had come into use, similar to the one illustrated by Fig. 8 of the foregoing statement, in which the depending air pipe and discharge pipe opened into a chamber which was placed above the pump cylinder. It is claimed on the part of the appellee that these latter pumps were better adapted for use in deep wells with a small bore or diameter than the Bean pump, as the chamber, F, could be located a short distance below [821]*821the platform, while the cylinder was placed much further down in the well.
