¶11. Reissued letters-patent No. 4289, granted March 7,1871, to George Crouch, for an improvement in straps for shawls, are void, by reason of the prior knowledge and public use of the invention which they describe.

¶3Appear from the Circuit United States · Case Law">Court of the United States for the District of New Jersey.
¶4This is a suit in equity by George Crouch against William Roemer to prevent the infringement by the latter of reissued letters-patent No. 4289, granted March 7,1871, to the complainant for an improvement in straps for shawls.
¶5Among the defences set up by the respondent was the want of novelty and the prior public use of the invention described in the letters. The remaining facts are stated in the opinion of the court.
¶6The court below sustained the defence and dismissed the bill. Crouch thereupon appealed.
¶7Mr. JE. B. Barnum for the appellant.
¶8Mr. Arthur v. Briesen, contra.
¶10delivered the opinion of the court.
¶11The appellant in this case, complainant below, in describing his invention, when he applied for his patent, said that before his. invention “ straps had been used to confine a shawl, or similar article, in a bundle, and a leather cross-piece, with loops at tbe ends, had extended from one strap to the other ;■ and above, *798and attached to this leather cross-piece, was a handle.” He then said: “ My invention consists of a rigid cross-bar beneath the handle, combined with straps that are passed, around the shawl or bundle, such straps passing through loops at the ends of the handle.” This was because the " leather cross-piece or connecting strap ” was “ liable to bend and allow the straps to be drawn toward each other by the handle in sustaining the weight; . . . hence the handle is inconvenient to grasp.-” From this, as it seems to us, the rigid cross-bar was, from the beginning, the controlling idea of the inventor. His object clearly was, not to bind and hold the bundle, but to keep the handle which the holder was to grasp from pressing the sides of the hand. Hence he says: “ I claim as my invention— 1. The rigid cross-bar, connecting the ends of the handle, and provided with loops for the- straps, substantially as and for the purposes set forth ; ” that is to say, to bind and hold a bundle to be carried. The drawings which accompany this application show that the inventor had in his mind straps which were to pass over the rigid bar crosswise, but there is nothing to indicate that they might not pass over the ends or through openings in the bar itself. Next he claims, “ loops made of the leather of the handle, and secured to the rigid cross-bar,” and then, “ the rigid cross-bar for a shawl-strap made of sheet metal, corrugated and covered with leather.”
¶12Clearly the defendant could not have infringed any other than the first claim. He did have a rigid cross-bar connecting the ends of a handle provided with openings, which were undoubtedly the equivalent of loops through which the straps to hold the bundle could pass ; but he had no loops made of the leather of the handles, and no cross-bar made of sheet-metal corrugated and covered with leather. Our inquiries are, therefore, confined to the validity of the first claim in the complainant’s patent.
¶13It is conceded in the patent itself that shawl-straps with handles attached to a leather cross-piece having loops at the ends were old. Eustace, one of the witnesses for the complainant, says he made his goods with a cross-piece of the firmest leather he could get, doubled and stitched, so as to render it firmer still. , His object clearly was to keep the weight of *799.tbe bundle from drawing tbe ends of tbe handle together so as to press against the sides of the hand.
¶14The testimony leaves no doubt on our minds that handles fastened on rigid cross-bars and used to carry bundles were known long before the complainant’s invention. Possibly in adjusting them to use, though this is by no means certain, the straps to bind the bundle were not passed through loops across the bar, yet it is clear, beyond all question, that the handle, rigid cross-bar, loops, or their equivalent, and straps, or equivalents, were used in combination to keep together and carry one or more articles in a package made by piling or rolling the articles together. Under these circumstances it was no invention to stiffen by artificial means the leather cross-piece which had before been made as rigid as it could be by thickness, doubling, and stitching. All that was done by this- inventor was to add to the degree of rigidity which had been used before. The addition of metal or other substance as a stiffener of the known cross-piece, which had already been made rigid in a degree, was not invention. The substantial elements of a well-known structure were thus, in no patentable way, changed.
¶15This view of the case makes it unnecessary to follow counsel in their efforts to break down or sustain the testimony of individual witnesses. The thing which the complainant claims to have patented was substantially made and used long before his invention. All he did was, by the use of known equivalents for some of the elements of former structures, to make it somewhat better than it was ever made before. This is not patentable.
¶16Decree affirmed.
