1. Letters-patent No. 4887, bearing date April 30, 1872, granted to Washburn ' Racé and S. !R. C. Mathews for an improvement in hydrants,- being a reissue of letters No. 19,206, dated Jan. '26, 1858, are void, inasmuch as, by claiming the elements of the invention separately and not as a combination, which is claimed in the original letters, they enlarge the scope of the lát-, ter, and they also cover a different invention. Miller v..Brass' Company ( 104 U. S. 350 ) cited and approved.delivered the opinion of the court.'
This case comes. before us.ori an appeal from a decree dismissing a bill in equity filed by Samuel R.
The Race and Mathews paténts, ■ on whichMihis suit was ■brought, relate to casings or jackets around hydrants, and to the valvésfor letting on the-water when wanted for' use, and for draining it out of the hydrant when not in use.. It is conceded that the objects of the casing are to, prevent freezing in and around the hydrant, by surrounding it- with .a volume of dead air, to keep it free from contact with the surrounding-earth; and to enable the hydrant to be taken out of the ground without removing,the surrounding earth. - If the earth is in contact with the hydrant, it lifts the hydrant out of place by the action of the frost,, and has to be dug away when repairs or other operations have to be performed below' the surface. Many casings formerly used were fastened in different ways to the hydrant, and they raised it, when they were lifted by the frost, causing breakage or leakage or other damage by the displacement; and the hydrant could ■ not be disconnected from the main and removed, "without removing the casing also. '
So far as the improvement' in the casing is concerned, the
As first patented in 1858, the invention did not accomplish the object. The.bottom of the case, it is true, surrounded the hydrant like a sleeve, and rested on a flange projecting from the elbow (which allowed the hydrant to be separately removed without removing the casé); but the top of the case ■was enclosed in a flange projecting from the enlarged part of the hydrant above, like the brim of a hat, but turned down over the top of the case, so that, the latter, though unconnected. otherwise with the hydrant, yet if it were lifted by the frost, it would press upward against the flange'and raise the hydrant also. This 'difficulty was remedied by the invention of the improvement patented in 1869, by which the top of the case was made to surround and enclose the upper enlargement of the hydrant, and to slide over it like a sleeve, as before stated. The reissued patent of 1872 substantially embraces both features of the improved case, namely, its disconnection with the hydrant both above and below, and places much stress on the dead-air- chamber as a'protection from frost, and on .the protection of the -hydrant' below from the surrounding earth; although no claim is based on these last features.
But the complainants, in their reissued patent, have, split up and divided the elements of their invention, and claimed them separately, and not as a combination;. Of course, this enlarges the scope of their patent. The separate claims embrace fewer elements in combination .than were embraced in the claim of the original patent. ' No one could infringe the original patent unless he used all the elements of the combination. Any one will infringe the reissue who uSes any of those elements which are now separately claimed.
The original patent had but a single claim in reference to the case, being a claim for a combination between the hydrant, the induction pipe provided with a flange to sustain the jacket, and the jacket itself, when arranged as described in the specification to effect the desired end, to wit, the ready, removal of the hydrant. This, in the reissued patent, is divided' into two claims, namely, first, the jacket surrounding the hydrant and
There is still another objection to the claims in question. There is a wide departure from the original invention in this,-that the subject of the latter was a jacket, or casing, whose top was ericlosed. and covered by a flangg projecting from the hydrant, which effectually prevented the removal of the jacket without removing the hydrant also ; and which-caused the hydrant to be raised when the jacket was lifted by the frost. Iri the reissued patent nothing is said ’ of this arrangement of the top of the jacket, and the claims ignore it altogether; so -that, as already intimated; the patent as it now stands would cover such á; jacket as that described and claimed in the -cornplainants’ patent of 1869, which slides like-a sleeve, over the hydrant at top as well as bottom. The reissue is not only for a broader claim made many years after the original was granted,.bat is for-a different invention. -Therefore, so far as the jacket is concerned, we think it cannot be sustained.
■ But the patent of 1869 still remains. That was for an improvement by which it was proposed to liberate the top of the case from the flánge which covered' and enclosed it, and make it surround the .hydrant and slip over' it like a sleeve. The claim is for “ the detached case B,. so combined and arranged with the hydrant-A, as to have an énd play, or vertical motion
As. to the valve apparatus, the object of which is to let the water in the body of the hydrant escape when the main valve is closed, and to prevent any escape of water when the main valve is open, since Race and Mathews were not the original inventors' of this process, but only of a particular arrangement of valves to effect it, they can only,properly claim the specific arrangement which.they invented. And in view of the older valve in the St. Louis hydrants, which that of the defendants most nearly resembles, .and' of' the fact that the valve used by the defendants is not m the specific form of that invented by Race and-Mathews, we think that the defendants are correct in. their position that they do not infringe the-patent of Race and Mathews, as that patent must be. construed in order to be sustained.
Decree affirmed,
