Metal type is cast in a machine having a mold of upper and lower blocks, into which the molten metal is forced through a funnel-shaped part of the mold at the foot of the type, and fills the mold, including this part, whereby the face and body of the type, with this excrescence attached, are cast. A forward movement of the mold separates the casting from the metal. Formerly an upward movement of the upper block carried the casting, held it in slightly by projecting pins, away from the lower block, until the end of the casting separated from the metal, [419]*419and called a “sprue,” should strike a finger, and the head a stool projecting from the lower block, and be withheld from the moving upper block till the casting would be released from that block, fall into a chute, and be carried away. The excrescence, called a “jet,” was separated from the body of the type by hand.
A patent, No. 187,880, dated February 27, 1877, was granted to Thomas Mason for an improvement in type molds, in the specification of which the parts of the mold blocks forming the jet are called “breaks,” and the invention referring by letters to drawings was described thus:
“In these breaks, angular or Y-shaped recesses, a, are formed, which, when the mold is closed together, are oppositely arranged in respect to each other, so that, when metal is injected into the mold, angular shoulders, b, corresponding in form to the recesses, a, are formed on each side of the break, c, of the type; so that, as the mold is opened with the type or casting in it, the contrary action of the oppositely arranged inclined sides of the recesses, a, produces sufficient strain to sever the break from the type, which is retained by the shoulders of the mold. The recesses in the breaks of the mold may be arc-shaped, or may have any other form which will effect the severing of the break.”
This suit is brought for alleged infringement, in the same machines, of claims 1, 2, 3, 4, and 6 of patent No. 352,869, dated November 16, 1886, for a mold for casting type by which the jet is held in the stationary lower half of the mold by pins, and broken and separated from the body of the type by the rising of the upper half, carrying that with it away from the jet, to he released and dropped into one receptacle, while the jet is removed by an arm into another; and claims 1, 2, 3, and 4 of patent No. 354,060, dated December 7,1886, for a mold for casting type, having recesses in the jet part of the lower half for casting detents upon the jet, to be struck by an arm moving close to the jet end of the mold, to release the jet from the mold,—both of which were granted to Carl Hochstedt, Philipp Wenzel, and Herman Heinehtich; and of claims 4, 5, 6, and 7 of patent No. 354,935, dated December 28, 1886, and granted to George Rettig, for a type-casting machine having an arm connected with another arm or lever, called “D,” pivoted to any part of the machine fitted in a position relative to the lower part of the mold, and connected by a link, called “D',” to a part-as an arm, E, moving when the mold is open, for moving the arm, D, past the jet end of the lower half of the mold, to strike the projecting points of the jet, and dislodge it.
The several claims involved are, in their order:
(1) In a type-casting machine, the combination, with the lower stationary member of the mold, having a detaining device in the jet-casting portion, of the upper mold section, provided with similar detaining devices in the typecasting- portion, substantially as described.

The defenses set v. are want of patentable invention, anticipation in prior patents, the nearest and most important of which is that to Mason, and prior knowledge and use, the most apt being what were involved in the operation of machines made after the Mason patent. The working faces of the shoulders of the recesses in the jet mold of the Mason patent appear to slant away from the body mold, so that, as the mold blocks separate, they slide like cams on thp shoulders of the casting in the recesses, and force the jet away from the body of the type lengthwise, and break them apart; and witnesses testify that, in the operation of the machine, the castings hold the jet in the lower block, while the raising of the body in the upper block, by that motion crosswise, breaks them apart. The machine is said to have been a failure. It appears, however, to have been operative as a mechanism in all its parts, but [421]*421not profitably for its purposes, and not a financial success. It cannot be disregarded as having been wholly abandoned.
The connection to be broken by these machines between the body of the type and the jet is so small, and the movements necessary to break it are so slight, that: it would seem difficult to tell that the separation was not effected in the Mason machine by the lengthwise motion before the blocks would be separated far enough to do it by the crosswise motion; especially as the recesses do not appear to he adapted to hold the jet firmly down in its place as cast in the lower mold so but that it might follow the crosswise motion of the body of the type till separated by the lengthwise motion, without being separated by the crosswise movement. That it operated to break crosswise unexpectedly, instead of lengthwise, as the inventor intended, does not seem to be established beyond any reasonable doubt, as is necessary in proving anticipation to defeat a patent. So, this anticipation must stand upon the Mason patent itself, which appears to be for the peculiar shaped recesses in the jet mold for drawing the jet away from the body of the type, and loosenjng it in the mold, rather than for holding it in the mold while the body of the type is broken away from it; as the use under it must be considered to have produced merely that operation. The other alleged anticipations are so much more remote than this that no discussion of them, after disposition of this, seems to be at all necessary. None of them comes anywhere near holding the jet in the lower half of the mold while the body of the type is carried away in the upper half, and separated from it. The claims involved are, in this view, considered to be valid for these improvements.
The denial of infringement has not been made prominent at the argument, the principal contention being as to the validity and scope of the claims, which being established, the plaintiff is entitled to a decree. Decree for plaintiff.
