257 F. 302 | 8th Cir. | 1919
This appeal questions the decree of the District Court that Einlay R. McQueen was the original inventor of the combinations and improvements illustrated by letters patent No. 896,233, issued to him on August 18, 1908, on his application filed June 20, 1907, and particularly pointed out in the first and second claims thereof, that the plaintiff below, the Barnett & Record Company, a corporation, is the owner thereof and of all claims for the past use thereof, that the first and second claims of the patent are valid, that the defendants have infringed those claims, and that the plain
In this court counsel for the defendants contend that the decree should be reversed, because the evidence establishes the facts that the patent of the combinations of-claims 1 and 2 is invalid, that McQueen was not the first inventor thereof, and that the conception and reduction to practice of the combinations there claimed did not constitute invention. They concede, however, that if neither of these positions is tenable the defendants were guilty of infringement.
The combinations described and secured by the patent relate to improvements in working grain elevators as distinguished from storage elevators. They relate to that type of grain elevator in which the grain may be cleaned, graded, weighed, otherwise worked, and distributed as in working elevators, as well as received, stored, and shipped, as in storage and terminal elevators. At the time McQueen conceived his combinations, an approved type of such an elevator consisted of a workhouse, of circular grain bins, supported by walls or girders and columns above the workhouse, and of a cupola or tower of four or five stories above the bins, wherein the machinery for elevating, spouting, garnering, weighing, and cleaning the grain could be located and operated. Prior to 1905, when McQueen conceived his combinations, such working elevators had been generally constructed of wood or metal, although the basement or the structure beneath the bin floors had often been made of masonry or reinforced concrete. The reason why the bins in such elevators had not usually been constructed of masonry or reinforced concrete seems to have been that the weight of the latter was so great, that the expense of supporting them over the workhouse upon columns and girders or walls was so great, and the necessary columns or walls occupied so much space in the workhouse, that iron or steel, or even wood, bins had been thought preferable to masonry or concrete bins. The danger of fire, however, and the great amount of w°°d requisite to resist the pressure of the grain, gradually diminished the use of wood, and there were serious objections .to metal as material for such bins. Unless the walls of metal bins were made very thick and heavy, of unless they were very strongly and heavily braced and tied with metal- rods, they were liable to buckle, crack, or tear open, when one of two or more adjacent bins was emptied of its contents, while the others were filled, on account of the-pressure of the grain upon the vacant bin.
During the years between 1895 and 1905, the use of metal reinforced concrete had rapidly increased, and its advantages as a building material had become more and more evident, until builders of working elevators became anxious to construct grain bins for working elevators of reinforced concrete or masonry, but in the then state of the art very heavy and expensive walls, or heavy and expensive girders resting upon many columns, were indispensable to sustain bins of such material over a working house, and such walls, or columns and girders, were so expensive and so cumbered, and occupied so much space! in the working house, that they practically prohibited the use of concrete or masonry bins in elevators of this type. In order to
Up to the time that McQueen discovered the combinations of his patents, no one had succeeded in accomplishing this in the United States. McQueen discovered combinations of old elements that accomplished the desideratum, and embodied them in 'an actual, practical, monolithic structure by means of which the cost of such practical working elevators was reduced about from 12 per cent, to 25 per cent. Working elevators with concrete metal reinforced bins constructed in accordance with the claims and specification of his patent speedily came into common use, and achieved abundant commercial success, so that, when the defendant came to construct the infringing elevator, it selected and built its elevator on the principle of McQueen’s combinations, which it embodied therein.
McQueen, in his patent, limited the material in which the bins of his combinations should be embodied to masonry or metal reinforced concrete, preferring the latter. Speaking, then, of concrete, although what is hereafter said is equally applicable to masonry, the principle of McQueen’s combinations, and. of the working elevator in which he embodied them, is the hanging or suspension above the working house of numerous cylindrical metal reinforced' concrete grain bins, placed close together in parallel rows in two directions, so that each bin shall be supported at two diametrically opposite points only, and only by columns, made of the same material as the bins, founded on the heavy concrete basement floor of the working house, rising vertically through the working house and the bin floor, made of the same material, and extending, on diametrically opposite sides of each bin, between the tangentially abutting sides of it and the adjacent bins, unified and made into one monolithic structure with the adjoining bins respectively, between which each column extends from the top to the bottom thereof, by metal reinforced vertically extended connecting bodies of the same material, which include and become one with these columns and the adjoining bins respectively, and extend from top to bottom of the bins, each of which bins is also united at its two other tangentially abutting portions, along which no column rises, by like metal reinforced vertically extended bodies made in one with the two bins between which they respectively extend from top to bottom, so that the columns, the bins, the vertically extending bodies of metal reinforced concrete between the tangentially abutting portions of the bins, are all rigidly united and made into one homogeneous monolithic structure, hung upon and sustained above the working house, so that the bins are suspended only at two diametrically opposite points by the columns which have been described, and by those columns only which sustain the entire monolithic structure and the cupola above the bins, which was preferably made of metal and sup
McQueen’s two claims here in suit read in this way:
“1. The combination with a multiplicity of masonry bins having their axes arranged in rows in two directions and having their tangentially engaged sides rigidly united by masonry body portions, certain of which constitute column extensions, and supporting columns below said bins vertically aligned and united with said tangential column extension portions of said bins and serving- to support the said bins only at two diametrically opposite points, substantially as described.
“2. The combination with a multiplicity of bins having their axes arranged in rows in two directions and on lines that intersect each other approximately at a right angle and having tangentially engaging sides united by vertically extended masonry body portions, certain of which constitute column extensions, supporting columns below said bins, vertically aligned and united with said tangential column extension portions of said bins and supporting said bins at two diametrically opposite points only, and certain of which bins are further connected by transverse tie walls that extend from top to bottom of said bins and form, on opposite sides of the tangentially connected portions of the bins, spaces through which elevator legs may be passed, substantially as described.”
No good purpose would be served by attempting to embody the history of this art, or to portray its state in 1905, when McQueen conceived his alleged invention, in this opinion. It will be sufficient to notice the prior patents, publications, and structures, which appear from the testimony to be those most closely resembling the devices of McQueen. Mr. Browne, the main witness and the expert for the defendants, testified that in his opinion patent No. 37,134, to George II. Johnson, issued December 9, 1862, came nearer than any others to showing the complete combination of claim No. 1 of McQueen’s patent, but that he had found no prior patent, publication, or structure, which disclosed the entire combination of either the first or second claim thereof. This patent to Johnson clearly demonstrates the fact that he was trying by the improvements he describes therein as early as 1862 to find some way to remedy the defects of cylindrical iron grain bins. He writes in his specifications that previous to his invention storehouses for grain had been constructed of cylindrical iron bins, arranged vertically and in contact with each other, and that the spaces between the bins had been employed as supplemental bins, but that when the grain was drawn off from one of these iron grain bins the sides were apt to collapse, not being of sufficient strength to resist the pressure of the grain in the filled bins adjacent to them. To remedy this evil he described and claimed small cylindrical iron bins placed in the spaces between the larger bins, and wrote that, while that feature was applicable to iron cylindrical bins, he had shown it with other features, which he claimed as applied to a new construction of bins and cylinders formed of brickwork tied together by means of plates and rods of iron. He then described cylindrical
Among other alleged anticipations or in the evidence to sustain lack of invention to which counsel for the defendants refer are:
Patent No. 24,424, to Badger and Sampson, of June 14, 1859, for the substitution of brick, stone, or iron square or tubular grain bins for wooden bins, which discloses such bins standing on a platform supported by two sets of arches beneath them, sustained on columns beneath the arches. But this disclosure lacks (1) the exclusive location of the supporting columns vertically under’the tangentially abutting portions of the bins; (2) the continuous columns extending from basement floor of workinghouse through the bin floor between the tangentially abutting portions of the bins to their tops; (3) the body portions extending vertically between the tangentially abutting portions of the bins through their entire length rigidly uniting in one monolithic whole the bins and tire columns between the bins; (4) the hanging or suspension of the. bins and the entire, monolithic structure on the continuous columns made in one therewith only at two diametrically opposite points of the bins, and other less material elements of McQueen’s combinations, while it portrays the double arches and the unnecessary columns under the bin floor which it was one of the objects of McQueen’s improvement to dispense with.
Patent No. 777,730, to Jamieson, issued December 20, 1904, for a complex, confused, and complicated method of binding together concrete and metal in a grain bin structure consisting of columns and bins which lacks (1) the cylindrical bins; (2) the working house beneath the bins^ (3) the suspension of the bins above the working house by continhous columns only at two diametrically opposite points of the bins; (4) the tie walls and the spaces for the elevator legs of McQueen’s conibinations.
Patent No. 662,452, of November 27, 1900, to James Macdonald, for combinations of cylindrical sheet metal grain bins in the form of nested bins in a storage warehouse which lacks (1) the work
All these and all the other less material patents presented by the . record, have been carefully examined, but none has been found which comes nearer to disclosing the combinations of McQueen, or to an anticipation thereof, than the patent to Johnson which was first discussed, and this court is not persuaded that the Johnson patent, or that any of the patents disclosed in this record, fairly anticipated the combinations of the claims 1 or 2 of the patent to McQueen.
Counsel has cited as an anticipation of these claims the copyrighted book of the Architectural Iron Works of the year 1865 at pages 7, 60, 61, 62, which portrays the Brooklyn Iron Elevator. This iron elevator was a storage and transfer elevator constructed to store and transfer grain from cars to ships. It was built about 1865, and torn down about 1902. It was provided with cylindrical iron bins “made like boilers of riveted plate iron” arranged in rows at right angles, supported on a flat floor, which rested on iron girders, sustained by iron columns beneath the girders. It contained somewhere between 60 and 90 bins. The testimony is conflicting on the question whether the columns were located vertically beneath the tangentially abutting portions of the bins, or vertically beneath the centers of the bins. The evidence for the former location consists principally of the description in the book of the Architectural Iron Works and the testimony of witnesses who saw the elevator before it was torn down, or the site of it after its removal. The evidence for the latter location consists of the blueprints of the drawings, made by George H. Johnson, the engineer for the construction of the elevator, which were found after his death among his papers, and which showed the columns vertically under the centers of the bins, and the testimony of witnesses to the discovery of these plans and the-preservation of them. There was also testimony upon each side of tins question of witnesses relative to the interpretation or meaning of the disclosures in the book of the \ Architectural Iron Works and the plans and sketches which were introduced in evidence. All this evidence has been carefully and repeatedly examined. But in the light of the fact that the witnesses who saw the elevator testified more than 12 years thereafter, of their uncertainty as to the details of the construction, and of the unreliability of the memory of men after so many years, and of the established rule of law that the burden was upon the defendants to prove the location of these columns by clear, convincing, and satisfactory evidence, the proof in this record has failed to convince that the columns of the Brooklyn Iron Elevator were .located vertically under the tangentially abutting portions of the bins, or that it embodied either the principle or the combinations of the first or second claims of the pat
About the yeafl 1901 at Buffalo, N. Y., an elevator was built, called the Dakota, wherein iron or steel cylindrical bins were supported by four continuous iron or steel columns to each bin, extending vertically between the abutting portions of the bins. It is persuasively argued that this elevator! anticipates thé combinations of McQueen, and demonstrates the fadt that there was no invention in conceiving and rer ducing them to practice, because it required no exercise of the inventive faculty to merely substitute masonry or reinforced concrete for iron or steel in ¡this elevator, or to reduce the necessary number of supporting columns 50 per cent. Conceding that there is ordinarily no invention in ¡the mere substitution in the construction of a building or elevator of one equivalent building material for another, it is too broad a statement to declare that there may never be invention in the substitution of one building material for another, and that is well illustrated by the story of this art. Johnson in his patent in 1862 suggested and ¿(escribed cylindrical bins of masonry supported on a floor resting on ¡masonry, brickwork, or iron. It was not, however, until some 40 years after that, that metal reinforced concrete came even into limited use for cylindrical elevator bins, and then these bins were not suspended above a workhouse by continuous columns made in one with them and with other parts of the structure, as in McQueen’s combination, but they were based on heavy masonry walls, or on heavy girders and columns of metal beneath them. The uses and capabilities of reinforced concrete, well known in this year 19.19, were so far unknown in 1862 that there can be no doubt that it would then have been a novel and useful invention to have conceived and reduced to practice an elevator building, according to the plan of McQueen. Johnson’s patent does not appear to have brought within the reach of the skill of the mechanic a practical and useful working elevator made of metal reinforced concrete, or of masonry based on and supported by heavy walls and columns, until about 40 years after the date of his patent, and neither Johnson’s nor any of the other patents or structures disclosed in this case, nor all together, appear to have enabled any one to conceive and reduce to practice or commercial use in this country such a metal reinforced solid monolithic
This result has not been reached without a thoughtful consideration of the testimony of witnesses and of the other structures, publications, plans, and sketches which this record contains. Mr. Browne, the expert and main witness for the defendants, testified that in his opinion the Brooklyn Iron Elevator more nearly resembled the structure of McQueen’s combinations than any other structure disclosed by the evidence, and Mr. Carter, the expert for the plaintiff, testified that in his opinion the Dakota Elevator enjoyed this distinction. As neither of them anticipates the patented combination of McQueen in suit, and no structure more nearly resembling McQueen’s elevator has been discovered by the court from the evidence in this case, it is unnecessary to discuss the other disclosures at length.
75Before reaching this conclusion the opinion of Judge Cassels in 13 Exchequer Court Reports, Canada, 186, was carefully considered. It does not, however, rule the material issues in this case, because his question was the validity of McQueen’s Canadian patent, the Montreal Harbor Elevator was available in his case as evidence of anticipation of that patent, and the sections of the Revised Statutes of the United States which make that structure unavailable as such evidence in the case in hand did not govern there and were irrelevant to the issues in his case.
The evidence and arguments of counsel for the defendants to the effect that the combinations of the second claim, which consists of the combination of the first claim with the transverse tie walls that extend from top to bottom of certain of the bins, and form on opposite sides of the tangentially connected portions of the bins vertical spaces through which elevator legs may be passed from the cupola, through the concrete or masonry structure to the working house below. one on one side and the other on the other side of the tangentially connected portions of the bins, was anticipated by the Dakota Elevator, the Great Northern Elevator, the Rialto Elevator, and other structures, and by the patents to Johnson, to Macdonald, and to others, and was not patentable, have not been overlooked. But, as neither of these structures or patents contain the combination of the first claim of McQueen, it does not contain the combination of the elements of that claim and the additional elements of the tie walls and spaces for the elevator legs described in the second claim. The question is not whether or not the tie walls and the spaces for the elevator legs were anticipated or patentable considered by themselves, but whether or not the combination of them with the combination of the elements of the first claim was patentable, and the court is not persuaded that it was not.
It is so ordered.
