P"-TBNTS I'OR INVENTIONS-ExTENT OJ!' CLAIM-CRE-CRUSIlERS.
Aolaim for a mill constructed of a conical shape, and having an eccentrio motio. In the manner set forth, is not a broad claim for any mill having such shape and motion, irrespective of its other features of construction and operation. Words of limitation in claims are not to be disregarded, and claims cannot be broadened by eliminating or disregarding such words.
8.u4E-PATBNTABILITY-PRIOR STATE OJ!' ART-CIlILLED BE"-RINGS.
Chilling bearings and wearing parts are old in the arts, and it does not require invention to chill any known bearing. Gates did not make any invention in chilling Brown's bearings.
Bearings similar in construction and operation cannot be differentiated from each other by chilling one of them. '

In Equity. Final hearing. Sllit was brought for alleged infringement of eight patents, and proofs made as to seven, to-wit; Nos. 56,793, to H., Pierce; 201,646, to C. M. Brown; 243,343, 243,545, 246,608, 250,656, to l'. W. Gates, known in the record as Gates' patents Nos. 1, 2, 3, and 4, respectively, all of which were for improvements in stone or ore-crushers; Nos. 110,397, to J. H. Rusk, and 237,320, to G. & A. Raymond, for improvements in break-pins for grinding-mills. Coburn Thacher, for complainant. West Bond, for defendants. ·
GRESHAM, J. The single claim of the Pierce patent reads: "The construction of a conically shape<1crushing-mill, with an eccentric motion .as herein described, for the purposes and in the manner substantially set forth." The claim is not broadly for the construction of a conically shaped crushing-mill with. an eccentric' motion. The very language Of the claim limits it to a mill constructed in the manner substantially 81!1 set forth, and the claim, thus construed, describes a mill, or machine, v.42l':.no.1-4

The first claim in Gates' patentN6. 3, '(the chiefclaim in controversy,) is for a new article of manufacture, namely: "A segmental 'p6rtionOf the: babbltJted\': so tha,t:wheiHt becomeswol!n it I may, beremovedj'and a newsegmentalbeanngsubstituted in itsplaee.'''

The alleged invention in Gates' patent No.4 is summed up and embra-ced in the fourth claim which reads: "The shaft ofanore-crushiJ;lg machine provided with a hard metal plate on its lower end, in combination with an adjustable sliding step-block, an oil-step box, and a bearing for the sbaft, substantially as and for tbe purpose specified." Before tbis claim was allowed, the patentee was required to amend bis applica,;, tion by inserting the words, "the adjustable sliding," and the alleged infringing machine contains no such sliding block. The mere attachment of a hard metal plate on or in the lower end of the shaft, admitting that Gates was the first to do it, involved no invention. But if it did, it consisted in theimprovemellt of one of the elements of the combination, namely, tbe shaft, and did not affect the combination claim. Steel wearing, or hard metal plates, were old, and Gates did nothing m()re than any intelligent mechanic skilled in the art might have done. The shaft with the in-set plate operated in the combination just as it did before. No new or improved,result was produced. With the exception of the inset oftbe wearing plate, the drawings of the Brown & SbOville No.1 machine show the combination described in the Gates No. 4 tent. Indeed, the drawings of the old Brown & Scoville machines showGates'patent No.4 to be worthless. I find that the Brown drawings anticipate the Gates patents No.1, No.2, and No.3, and that Gates' patent No. 4, contains no claim for the insetting of tbe plate, and that that patent, too, is anticipated by the samedrawingl:l. In connection with the Gates patents, comp1l1ill!l.nt's counsel and experts have failed to give proper weight to the Rutter patent, the Brown patent, and the two Brown &: Scoville machines, especially the two latter machines. Gyrating shafts were in use before the date of any of the patents owned by the plaintiff.. The patentee simply took the old gyrating shaft, and applied common devices to it. ' . The first claim of the Rusk patent reads: "The combination, substantially as described, of soft metal pins or plugs. 0, 'with the driving gear of the grinding-mill." Rusk expressly limited himself to it soft metal pin, and his claim cannot be enlarged by construction. Thus limited, the claim is not infringed for the defendllllts' use, not a soft metal pin, but a hard cast-iron pin, and their machine does not show in'use inmachines of different the Rusk driving gear. kinds before the of the Rusk patent. The idea of the break-pin, broadly, was not original with Rusk. With the exception of the pin being somewhat more a(:cessibIe, the Raymond patent is not from the Rusk patent. ' . Briefly, these are my reasons for dismissing the bill. 'Later, I may give a fonnal opinion.· :;'
