Opinion

BUFFINGTON, Circuit Judge.

In the court below T. B. Wood’s Sons Company, the plaintiff, by its bill charged the Valley Iron Company with infringing patent No. 790,609, granted May 23, 1905, to Charles D. Wood, for a shaft hanger. That court, in an opinion reported at 206 Fed. 172, held infringement had not been established. From a decree dismissing the bill, plaintiff appealed.

A. 46) we noted that the surfaces on the top and on the bottom of the bearing-box, with which the large top and bottom screws engaged to hold the box, were cylindrical in form, and that this cylindrical form had the functional effect of allowing a variation in the position of the box. 'Vyhat we there said was:

“Tbe invention thus appears to consist of a combination by which the box wbicb supports tbe shaft may be readily adjusted to any position of the shaft vertically and horizontally with firmness and accuracy. Tbe patent accomplishes this by means of horizontal screws on tbe sides and large screws on tbe top and bottom; these last screws having plain surfaces, but bearing upon a countersunk cylindrical surface or a flanged cylindrical surface. The surface upon wbicb tbe flat screw bears allows a variation in position of tbe box; but, when once adjusted, tbe flat surface of the screw has sufficient bearing to prevent further movement when tbe large screw or flange is fastened with a set screw.”

The cylindrical form was thus noted in pursuance of the disclosures of the specification and the limitations of the claims. In that regard the specification says, referring to accompanying figure:
