ERROR to the Circuit Court of the United States for the District of Massachusetts.
Woodman sued Stimpson, in the court below, to recover damages for an infringement of a patent granted on the 29th March, 1864, for 'a new and useful machine for ornamenting leather,' as stated in the letters patent. In the specification the plaintiff stated that he has 'invented a new and useful improvement in boarding or pebbling leather,' and describes how this process was formerly carried on. He says:
'What is known as a boarded or pebbled grain or finish, has hitherto been given to leather by what is called the boarding operation, which consists in doubling the skin over on to itself on a table, so that the flesh side shall be out, and then forcing or rucking one part over the other, in different directions, by means of a flat 'cork-board,' which breaks or wrinkles the grain, and gives it a rough, checkered, or pebbled appearance. This operation is performed by hand, and is very slow and laborious, and produces only one particular kind of finish.'
He then observes:
'The nature of my invention, therefore, consists in producing this 'pebbled' or 'boarded' grain or finish on leather, by subjecting it to the pressure of a short revolving cylinder or roller of steel, or other suitable metal, having the required design or figure engraved or sunk on its periphery. . . . My improvement further consists in combining with said roller a certain new and useful combination of mechanical devices for carrying my invention into practical operation, so as to accomplish the object desired with great rapidity and cheapness.'He further observes:
'It is obvious that my 'pebbled' roller may be combined with various mechanical devices, whereby it can be rolled with sufficient pressure over a skin of leather. I will, however, now describe a combination of devices which I find to answer every purpose required.'
The plaintiff then describes with great minuteness the machine, and every part of it, and closes with his claims:
'First. Boarding or pebbling skins or leather by means of a single short cylinder rolling over a table with the requisite pressure, substantially as described.
'Second. I also claim raising and lowering the table 'A' by means of the toggles 'Q,' arm 'S,' spring 'U,' arm 'T,' and cam 'P,' or their equivalents, substantially as set forth, and for the purposes described.'
The second claim was not in the case, as the arrangement or contrivance was not found in the defendant's machine. The first was the only one in question. That, as already stated, was 'boarding or pebbling' skins or leather by means of a single short cylinder rolling over a table with the requisite pressure, substantially as described, which means, as this court stated that they understood the claim, finishing or figuring the leather, by means of a revolving roller, the design or figure engraved or sunk on its periphery, and worked over the grain of the leather by the use of the machinery described, or by machinery substantially like it.
It was admitted, in the bill of exceptions, that evidence was given on the trial, by the defendant, tending to show that prior to the plaintiff's invention, boarded or pebbled grain or finish, described in his patent as produced by him, had been produced on leather by subjecting it to the pressure of a short revolving cylinder of steel or other metal, having the required design or figure engraved or sunk on its periphery, and rolling over a table upon which the leather was placed; and that the said revolving figured cylinders, which are known in the case as 'pebbling rollers,' were operated with the requisite pressure by means of hand devices.
