Opinion

EVANS, Circuit Judge.

Plaintiff sought damages and an injunction to prevent future infringement of patent No. 705,732, issued July 29, 1902, upon application filed April 21, 1899. The bill was dismissed upon a finding of no infringement.

The patent under consideration, relates to a retaining wall of the cantilever type, and is described by the patentee as follows:

•‘My invention relates to improvements in retaining walls for abutments of bridges, seawalls, banks of streams, embankments, cuts, dams, dry docks, and such places as it is desired to retain earth or other matter permanently in place with its face at an angle nearer vertical than it would naturally repose when exposed to the action of the elements or gravity. * * * The said invention consists principally of introducing into masonry of concrete, stone, or brick a framework of steel or iron in such a way that the whole wall is so much strengthened thereby that the volume of the masonry may be greatly reduced, and yet the height, base, and strength against overturning, bulging, or settling will still be ample.”

Again he says:

“I am aware that retaining walls have been constructed of concrete and steel, but none to my knowledge (1) have been supported on their own base as mine; (2) nor have any of tnem entirely inclosed the steel within the concrete ; (3) nor have any of them used the weight of the material retained as a force to retain itself.”

Claims 1, 3, 5, 16, and 17 are involved in tire present suit. Claims 1 and 16, which are typical, read as follows:

“1. The combination, with a retaining wall having a heel, of a metal structure imbedded vertically in said wall and obliquely in said heel, so that the weight of the retained material upon the heel of the metal structure will pperate to retain the wall in vertical position.”
“16. The combination, with a retaining wall having a heel and a toe at opposite sides thereof, said toe having an independent metal structure imbedded therein, of a metal structure imbedded within said wall and heel, said structure consisting of upright bents at the back part of the vertical wall and continuing down along the upper part of the heel of said wall to the back part thereof, so that the weight of the retained material upon the heel of the metal structure will operate to maintain the wall in a vertical position.”

Defendant maintains: (a) That the patent is anticipated by the prior art; (b) if not so anticipated, the claims must be so restricted and construed as to support the finding made by the trial judge that there was no infringement.
