This gidt is upon three letters patent granted to William Goldie, namely: No. 391,118, dated December 4, 1.888, for improvements in spikes, and more especially spikes used in the construction of railroads; No. 418,841, dated October 22,1889, for a spike-pointing machine; and No. 413,842, dated October 22,1889, for a method of pointing spikes.
The distinguishing feature of the Goldie spike consists in its having a point provided with diagonal catting edges located in the same perpendicular plane with its rear side, and a compressing surface on its front side, formed with oblique facets on the front sides of the cutting edges; the diagonal cutting edges, as the spike is driven into the wood, dividing the fiber with a clean, shearing cut, whereby is obtained a square-cut backing or solid supporting; wall to bold the spike against the crowding strain of the rail, while the oblique facets turn and compress the ends of the severed fiber [238] outwardly towards the side grain of the timber, so that they bear with great friction on the body of the spike, which is held firmly in the tie.
The claims of this patent are:
“(1) A spike having a point provided, on each side with diagonal cutting edges located in the same perpendicular plane with its rear side, substantially as set forth.”,
“(2) A spike having a point provided with a sloping compressing surface on its front side, and with cutting edges, p, p, located in a plane with the rear side of the point, and diverging from the center diagonally upward to the lateral sides, and with the oolique facets, o, o, on the front sides of the said cutting edges, substantially as set forth.”
[We herewith publish from the records of the United States patent office drawings of the G-oldie spike, patented December 4, 1888, letters patent Ho. 394,113.]
Goldie’s method of pointing spikes consists in swaging the point to form front and rear compressing surfaces, and then producing a sharp edge by shearing off the surplus metal obliquely across and in the direction of the length of the grain or fibei of the rolled iron. His spike-pointing machine consists of a vertically reciprocating plunger provided on its lower portion with one or more cutters of a shape to conform to the shape of the cutting edges required on the spike, and with a gage stop projecting below and in the rear of the cutters, and an anvil die having its upper face arranged to support the spike in a position oblique to the movement of the plunger, and having its front lower edge fitted to conform to the cutter or cutters on the plunger.
The Goldie spike, which was first put on the market in the year 1889, has met with unusual public favor. It has gone into very extensive use upon lines of railway all over the country. The un-contradicted proofs show that if is regarded by road masters and track officials generally as the best fastener for rails that has yet [239] been produced. It is also satisfactorily shown that the plaintiffs’ competitors in business (save the defendant company) have respected their rights under the patents in suit.
I have very carefully examined the numerous prior patents set up by the defendants as anticipating Goldie’s inventions, or as showing want of patentable novelty in what he has done. I am, however, quite clear that, no such effect is to be given to them. The Goldie spike seems to be a valuable improvement, evincing meritorious invention. .Nothing appears to create a doubt as to the validity of either of the patents sued on.
A specimen of the spikes manufactured by the defendants and here complained of is an exhibit in the case, and the question of the infringement of the spike patent (No. 394,113) is determinable by a more inspection of this exhibit. The plaintiffs’ spike and the defendants’ spike differ in this: that, whereas the spike shown in the patent has a. single point, the defendants’ spike has two points, each, however, being substantially the same as the Goldie point in form, function, and result. The two points in the defendants’ spike are produced by shearing away as well a central pari, of the metal as the sides, after the point is formed by sivaging. The central shear, indeed, is crescent-shaped; but this is purely a formal difference. The substance of the invention remains. The principle of the two* spikes is identical. The defendants’ spike is provided with diagonal cutting edges located in the same perpendicular plane with the rear side of the point, and with oblique facets on the front sides of the cutting edges. To all intents and purposes the defendants’ construction is a mere duplication of the Goldie point. The change which the defendants have made is a palpable evasion, and cannot here avail them.

AQPIESON, Circuit Judge.
This gidt is upon three letters patent granted to William Goldie, namely: No. 391,118, dated December 4, 1.888, for improvements in spikes, and more especially spikes used in the construction of railroads; No. 418,841, dated October 22,1889, for a spike-pointing machine; and No. 413,842, dated October 22,1889, for a method of pointing spikes.
The distinguishing feature of the Goldie spike consists in its having a point provided with diagonal catting edges located in the same perpendicular plane with its rear side, and a compressing surface on its front side, formed with oblique facets on the front sides of the cutting edges; the diagonal cutting edges, as the spike is driven into the wood, dividing the fiber with a clean, shearing cut, whereby is obtained a square-cut backing or solid supporting; wall to bold the spike against the crowding strain of the rail, while the oblique facets turn and compress the ends of the severed fiber [238] outwardly towards the side grain of the timber, so that they bear with great friction on the body of the spike, which is held firmly in the tie.
The claims of this patent are:
“(1) A spike having a point provided, on each side with diagonal cutting edges located in the same perpendicular plane with its rear side, substantially as set forth.”,
“(2) A spike having a point provided with a sloping compressing surface on its front side, and with cutting edges, p, p, located in a plane with the rear side of the point, and diverging from the center diagonally upward to the lateral sides, and with the oolique facets, o, o, on the front sides of the said cutting edges, substantially as set forth.”
[We herewith publish from the records of the United States patent office drawings of the G-oldie spike, patented December 4, 1888, letters patent Ho. 394,113.]
Goldie’s method of pointing spikes consists in swaging the point to form front and rear compressing surfaces, and then producing a sharp edge by shearing off the surplus metal obliquely across and in the direction of the length of the grain or fibei of the rolled iron. His spike-pointing machine consists of a vertically reciprocating plunger provided on its lower portion with one or more cutters of a shape to conform to the shape of the cutting edges required on the spike, and with a gage stop projecting below and in the rear of the cutters, and an anvil die having its upper face arranged to support the spike in a position oblique to the movement of the plunger, and having its front lower edge fitted to conform to the cutter or cutters on the plunger.
The Goldie spike, which was first put on the market in the year 1889, has met with unusual public favor. It has gone into very extensive use upon lines of railway all over the country. The un-contradicted proofs show that if is regarded by road masters and track officials generally as the best fastener for rails that has yet [239] been produced. It is also satisfactorily shown that the plaintiffs’ competitors in business (save the defendant company) have respected their rights under the patents in suit.
I have very carefully examined the numerous prior patents set up by the defendants as anticipating Goldie’s inventions, or as showing want of patentable novelty in what he has done. I am, however, quite clear that, no such effect is to be given to them. The Goldie spike seems to be a valuable improvement, evincing meritorious invention. .Nothing appears to create a doubt as to the validity of either of the patents sued on.
A specimen of the spikes manufactured by the defendants and here complained of is an exhibit in the case, and the question of the infringement of the spike patent (No. 394,113) is determinable by a more inspection of this exhibit. The plaintiffs’ spike and the defendants’ spike differ in this: that, whereas the spike shown in the patent has a. single point, the defendants’ spike has two points, each, however, being substantially the same as the Goldie point in form, function, and result. The two points in the defendants’ spike are produced by shearing away as well a central pari, of the metal as the sides, after the point is formed by sivaging. The central shear, indeed, is crescent-shaped; but this is purely a formal difference. The substance of the invention remains. The principle of the two* spikes is identical. The defendants’ spike is provided with diagonal cutting edges located in the same perpendicular plane with the rear side of the point, and with oblique facets on the front sides of the cutting edges. To all intents and purposes the defendants’ construction is a mere duplication of the Goldie point. The change which the defendants have made is a palpable evasion, and cannot here avail them. Hoyt v. Horne, 145 U. S. 302, 308, 32 Sup. Ct. 922. Infringement of this patent., I think, clearly appears.
With respect to the other two patents, the evidence of infringement is both direct and circumstantial. The defendants’ spike itself bears very strong indications that it was cut by a reciprocating plunger acting upon the metal while supported upon an anvil die in a position oblique to the movement of the plunger. Plainly, its sharp cutting edges were produced by shearing the metal obliquely across and in the direction of the length of the fiber. The faces of the cut show straight and continuous lines, while the under side of the spike has visible marks which can be reasonably accounted for only upon the supposition that when cut it rested upon an anvil die. Then we have the positive statement of David Ford, an experienced witness, who examined and describes with particularity the defendants’ spike-making machines. According to (he specific description contained in his affidavit, those machines are the same, in construction and operation, as the machine of the Goldie patent, or substantially so. How do the defendants meet this case? In their answer the denial of infringement is couched in the most general terms. George W. Todd, the president of the defendant company, and its codefendant, in his additional opposing affidavit does not at all explain the defendants’ machines or method. [240] Mr. Browne, the defendants’ patent expert, Mr. Griffith, their em-ployé, and Mr. George, their foreman, respectively deny the correctness of Ford’s description of the spike-making machines the defendants are using, and assert that Ford’s statements are “erroneous” and “wholly false and misleading”; that the defendants’ machines and methods are “radically and totally different” from Ford’s description, the machines operating in “an entirely distinct and different manner”; with other allegations to the like general effect. But no one of these affiants describes the machines the defendants are using, or their method of manufacture, or gives the court any specific information as to the actual construction of those mhchines, or their mode of operation. This reserve is significant. It is not satisfactorily explained. The plaintiffs’ proofs under this head are exceedingly strong, demanding something more than bald denials and vague general statements. The defendants should have given the court facts, and not bare opinions. Moreover, the three last-named affiants state that the defendant company actually has one machine made “in substantial accordance with the Goldie machine patent,” but intended and used, they say, “simply for the purpose of experiment.” The proofs, then, as a whole, I think, fully warrant the interposition of the court to prevent infringement of the patents for the Goldie machine and method.
The evidence tends to the conclusion that the defendants do not conform to the Bower and Todd patents, but in material respects depart therefrom. Be that as it may, however, those patents are for inventions of a later date than Goldie’s, and are subordinate to his patents.
The allegation that the plaintiffs have been guilty of such laches as should deprive them of summary relief is not well founded. In November, 1892, upon the first serious intimation of probable infringement, the plaintiffs addressed a warning letter to the defendants. Positive information of actual infringing sales did not reach the plaintiffs until May, 1893, and satisfactory proofs of infringement were not obtained until late in the year. Then the bill was promptly filed, and this motion made. There are no equitable considerations to induce the court to withhold preliminary relief. Interference with the defendants’ general business is not proposed. Their manufacture of infringing spikes began recently, and has not yet attained large proportions. On the other hand, to permit the defendants to put on the market the infringing spikes at an under price, as the evidence shows they have been doing, would seriously embarrass the plaintiffs, and inflict upon them “special injury which it would be very difficult, if not impossible, to compensate adequately.
A preliminary injunction in accordance with the prayer of the bill will be allowed.
