1. Patents — -Anticipation—Band-Saw Mills.

In the Smith patent, No. 442,645, for an improvement in band-saw mills, claim 1 of which is for the combination with the band wheels and main supporting frame or column of an integral standard carrying the front bearings of the upper and lower band-wheel shafts, the standard being attached to the front side of the main frame or column between the band wheels, the essential feature covered by this claim is the outside support for the front bearings of the hand-wheel shafts, which, as constructed, permits the removal and replacement of the band saw without difficulty or derangement of the machinery; and the claim was not anticipated by previous patents, none of which covered the combination in the same form, although its elements were found in them.

2. Same — Limitation on Claim — Pnion State or Akt — Inkeingemicnt.

As there was no invention in combining such elements found in previous patents, nor in overcoming their defects by merely increasing the strength of the parts, the claim cannot he construed broadly to cover the use of an integral outer standard attached to the main column between the band wheels, hut must be limited to the construction, shown of such outer support in the form of a single casting, as expressed in the application, stating the object to be to lessen the number of parts usually considered necessary; and hence that claim is not infringed by a combination in which the outside support is made of two parts, although they are bolted together so as to present the effect and produce the result of a single casting; and claims 2, 3, and 4, each of which merely adds to the combination of claim 1 an element found in previous patents, not involving invention, are1 not infringed by like combinations having the outside support so constructed. 57 Fed. 934, reversed.

3. Same.

Claims 5, G, and 10 of the patent, covering the straining device whereby tho saw is kept at the proper tension, all the elements of which, except the mechanism supporting the kmfe-edgod bearings of the rock shaft, are found in previous patents, is limited by such pre-existing devices, and hence is not infringed by the straining device of the Kooi’od patent, No. 4G8,303, the differences in the supporting mechanism being greater than the Changes) made by the Smith patent in adapting the previous devices. 57 Fed. 934, reversed.
