Opinion

BLATCHFORD. District Judge.

This suit is founded on re-issued letters patent of the l.'nited States, granted to Samuel P. Kittle, one of the plaintiffs, October 17th, 1865, for a “spring mattress.” on the surrender of original letters patent granted to him November Sth, 1864. The re-issued patent contains seven claims, but only the first two claims are alleged to have been infringed by the defendants. The subjects of these two several claims are defined by the specification in the following language: “The first part of my invention relates to the division of the sides of the box which contains the springs on which the hair mattress or other stuffing is supported, at two points, and connecting the said parts by hinges, in such a manner that the joints thereof shall be, at two points, distant from each other twice the thickness of the stuffing’, and so arranged that the head or foot portion of the bed can be folded over so as to bring the principal parts of the box parallel with each other, the stuffing being between them, as hereinafter more fully set forth. The second part of my invention relates to so constructing that portion of the box which forms the short section between the hinges or joints, as to make it capable of supporting a portion of the springs, while at the same time it is of such length as to allow the parts upon each side of it to be hinged to it, and connected to each other at two points on each side, at the distance apart of twice the thickness of the stuffing, as hereinafter more fully set forth.” The first and second claims of the patent are as follows: “First. The combination of the two parts. A and 'A', and an intervening portion of the sides of the box of a box-spring mattress, having the cases containing the stuffing attached to the said sides, the said parts, A, A', and the intervening portion, being connected to each other by hinges, the joints of which are located twice the distante apart of the thickness of the stuffing, substantially as herein above set forth. Second. The combination of the two parts, A, A', hinged at two points the distance apart of twice the thickness of the stuffing, the intervening part, A", and a series of springs supported upon slats, attached to the said intervening portion, A", the whole being constructed and operating substantially as herein above set forth.”

The object of the improvement covered by the first claim is to enable a box-spring mattress to be folded flatwise without material injury to the stuffing, which is mounted upon and connected with the box bottom containing the springs. The improvement consists in combining two parts of the sides of the box of the mattress with an intervening portion of such sides, by connecting them together by means of hinges, the joints of which are located twice the distance apart of the thickness of the stuffing, the cases containing the stuffing being attached as well to such two parts as to such intervening portion. The specification describes a division of the sides of the box at two points on each side.

The object of the improvement covered by the second claim is to make such intervening portion capable of supporting a portion of the springs, while, at the same time, it is of such length as to allow the parts upon each side of it to be hinged to it. and connected to each other at two points, on each side of the box, at the distance apart of twice the thickness of the stuffing. The improvement consists in [696]*696combining such two parts of the box, hinged at two points the distance apart of twice the thickness of the stuffing, with such intervening part, and with a series of springs supported upon slats attached to such intervening part. This construction enables the parts of the box on each side of the intervening part to be folded over so as to become parallel with each other, the spring-box and the mattress mounted on the springs being folded over by the same movement.

There can be no doubt that the defendants have infringed both of these claims. Their mattresses are of a like construction in principle to the mattress of Kittle, differing only formally in this, that the defendants’ box has each of its sides divided into five parts instead of three, each of the sides being divided at four points instead of two. The result is, that the defendants’ mattress has, in the middle of each side of the box, a long portion, on each side of such long portion, a very short part, corresponding with the intervening part in Kittle’s mattress, and, at each end of the length of each side, another part. These end parts can be folded over so as to become parallel with the middle part of the box, and to be in the same plane with each other. When so folded, the defendants’ mattress is, in effect, two of Kittle’s mattresses combined into one. It embodies each one of the two improvements of Kittle covered by his first and second claims, and embodies each one twice, each of the improvements being applied at each end of the mattress. If cut into two, through the space between the end parts when folded, and through the centre of the middle one of the five “parts, two of Kittle’s mattresses would be produced. There are the two outer parts, the intervening part, the box, the box spring mattress, the cases containing the stuffing attached to the three parts, the three parts connected to each other by hinges, the joints of the hinges located twice the distance apart of the thickness of the stuffing, and the series of springs supported upon slats attached to the intervening part, and all this in duplicate in each mattress, one of such arrangements at each end. The same result is attained by the arrangements, and in the same way, as in the patent. In such mattresses of the defendants as contain the arrangements above mentioned, except in not having the eases containing the stuffing attached to the parts forming the sides of the box, the second claim of Kittle’s patent is infringed. It may be that the defendants’ mattresses contain a useful improvement beyond what is found in Kittle’s patent. Whether they do or not is of no consequence here. They certainly embody what is patented by Kittle.

In addition to the defence of non-infringement, urged at the hearing, but not set up in the answer, the allegation of infringement made in the bill not being denied by the answer, the defendants attack the patent for want of novelty, various specifications in that regard being contained in the answer. Without going into a detailed discussion of the prior inventions set up, it is sufficient to say, that none of them embody what is covered by either the first or the second claim of the Kittle patent. The three principally relied upon are what are known as the “Putnam bed,” the “Colton folding bedstead and mattress,” and the “Cincinnati bed.” These are effectually disposed of by the testimony of the expert on the part of the plaintiffs, and there is no testimony in contradiction.

The defence really relied on, and which has caused the proofs in this case to be swollen to the bulk of some seven hundred printed pages, is a claim, on the part of the defendants, that what they have done in respect of their mattresses has been done under a right or license granted by Kittle under the inventions covered by the patent. The answer sets up, that, by a written instrument executed by Kittle and one Alexander D. Farrell, on the 11th of April, 1863, Farrell became interested in Kittle’s invention.
