Forgie v. Oil-Well Supply Co., 57 F. 742, 1893 U.S. App. LEXIS 2819 (circtwdpa 1893).

Opinion

BUFFINGTON, District Judge.

W. Forgie brings this bill against the Oil-Well Supply Company, Limited, for alleged infringement of á patent for wrench for oil-well tools, applied for January 28, 1888, and to him granted March 4, 1890, and numbered 422,879. The respondent is the selling agent of the Duff Manufacturing Company, which latter is the manufacturer of the alleged infringing machine, and the real respondent in the case. The device in dispute is a jacking apparatus for screwing and unscrewing oil-well tools. The respondents allege their device is made under patents issued to one Barrett, and. a suit against Forgie for alleged 'infringement thereof in his device was argued with this bill, and is disposed of in our opinion at No. 54, November term, 1891. 57 Fed. Rep. 748.

The present case turns upon two questions: (1) Was -Forgie the inventor of the device? and (2) if so, is the device patentable? Tools [743]*743for drilling oil wells weigh from two to three thousand pounds* and the sections of the drill rod consist of a tapered or conical screw’ and socket, which must be tightly screwed together. The drilling is done by raising and dropping them constantly, oftentimes on solid rock, and they are liable to be jarred loose; in which event serious damage may follow. They must be frequently unscrewed, to sharpen the bits, or to use other tools. Under the old system this W’as thus done: To the floor of the derrick, concentric with, and about three and a half feet from, the hole, a quadrant iron bar was bolted, having at one end a strong pin, and from thence to the other end, at regular intervals, holes adapted to engage the end of a pinch bar. Two powerful wrenches wTere then placed at right angles to each other on the suspended drill rod, one above and one below the screw joint it was intended to tighten; one wrench stationary, and in engagement with the pin, the other free to be moved from the other end of the quadrant towards the pin. This w’as done by inserting the end of the pinch bar in the holes of the quadrant, and forcing the movable wrench, step by step, towards the pin, until the joint was tightened. The same process, the relative position of the wrenches being changed, unloosened the joint. While the process was crude, laborious, and at times required a number of men, the evidence does not show any effort to improve it, although powerful jacking mechanism was in common use for raising weights, and also for moving bodies vertically. Some time prior to February, 1887, Forgie conceived the idea of adopting a jacking mechanism to this use. The practical working out of this idea resulted eventually in the construction of the devices in these suits. In Forgie’s device Ho. 1 the same wrenches we have described perform the same function, and accomplish the same result. The circular bar is provided with teeth, which are used as a shifting base for a movable jack, for the application of power, instead of the holes being used for that purpose with a pinch bar. Upon both sides of the bar a flange is placed, which fits into, and keeps from flying the track, a movable carriage, which contains the jacking mechanism. By means of this simple device, tools of much greater weight, and therefore more effective in drilling, are used, handled with greater ease, and with fewer men. It has gone into general use, and practically superseded the old method.

This brings us to the question, who was the inventor of this device? In February, 1887, Forgie first met Barrett, who was connected with the Duff Manufacturing Company. He was the patentee of the Barrett lifting jack, a powerful mechanism, then manufactured by that company, in common use, and a standard article. This jack was provided with a base, in which was a stationary jacking machine, and from which extended a lifting bar, which was forced upward against the weight desired to be moved. This lifting bar was kept in place by a rectangular slot in the cage surrounding the mechanism. The internal mechanism of the Barrett jack was adopted in Forgie’s device, the cage being adapted to move on the circular track, instead of remaining stationary. Forgie claims [744]*744that when he applied to Barrett he had perfected his invention, and simply wanted it made; while Barrett contends that, apart from the abstract idea of applying a jack to oil-well wrenches, he had evolved nothing.

In considering the testimony we have not overlooked the second testimony of Porgie, taken without leave of court after the case had been closed, for objection thereto was waived at bar. In this Porgie enters with detail into the completeness of his invention, where he first met Barrett; a detail of facts which does not appear in his former testimony, and upon which the case was closed. His explanation of this is that his former counsel had not asked him these questions, but, in view of the fact that it was explicitly claimed in the answer that “Barrett was the inventor and originator of all the material and useful parts of said improvement, and that he communicated the same to. 'William Porgie, and that said William Porgie surreptitiously applied for a patent upon the improvement of Josiah Barrett, and unlawfully obtained letters patent therefor;” that Barrett’s testimony was given in detail to support these facts; that Forgie was then called in rebuttal, when he gave what we have called his first account, — we think we are justified in giving-more weight to the first than to the second. If Porgie had invented the device previous to this meeting, the evidence fails to disclose any experimenting on his part, any sketches, drawings, models, or other footprints which usually mark the inventor’s pathway; and, indeed, a year after, when he made application for a patent, there was no suggestion of any other mechanism than Barrett’s jack. Whether Porgie knew of the mechanism of Barrett’s jack before they met is not certain. In his answer to the bill in the other case, Forgie says, speaking of this meeting: “I was aware at said time that the salid Barrett had not covered by his claims in his said letters. patent the use of the appliances, otherwise than a lifting jack.” In his first testimony, in answer to the question whether he had before that time known of the Barrett jack the company was then making, he says: “Ho; I don’t believe I ever saw a Barrett jack before I went to them;” that in describing his invention to some one they sent him to Barrett, giving as a -reason, “because he was making a jack similar, and would be a likely man to make them for me.” When his later testimony was taken, he says the first time he saw it was in the fall or winter of 1886, at Kay’s store, or-at the Fairbanks Company,-in Pittsburgh. Whether, as stated in the answer, he was acquainted with the very claims of Barrett’s patent at the time of this meeting, or whether, as stated in his first testimony, he had not seta it before, and only went because some one suggested Ms going, or whether he saw it first in the fall or winter of 1886, one thing is certain, — that before this meeting he had made no study with a view of adapting the Barrett jack to unscrewing oil-well tools. Barrett’s account of the meeting is as follows:

“Question. Please state the circumstances of your first meeting with Mr. Forgie. Answer. Mr. Forgie came to me about February. He said he had been di[745]*745rected there from Kay Bros. & Co., Water street, and said he had seen my jack, and had an idea that it could be applied for wrenching and unwrenching oil-well jacks. He then proceeded to describe the old method of .the circle plate and pinch bar, and described how difficult it was to unwrench and wrench the tools with this appliance.
