Opinion

SHIPMAN, Circuit Judge.

Letters patent to John E. Atwood, No. 253,572, dated February 14, 1882, for an improved support for spindles in spinning machines, were the subject in a bill in equity in this court between the parties in this case, and were adjudicated upon in a decision which was filed September 26, 1892, (52 Fed. Rep. 590,) and in which the second, third, and fifth claims of the patent were held to be valid, and to have been infringed upon by the defendant’s spindle, known in the case as the “Morrison Spindle.” Subsequently the present bill was brought to prevent the manufacture and sale by the defendant of the spindles known as the “Hammond and Dady Spindles,” and which were a modification of the device the manufacture of which had been enjoined. Upon a motion for preliminary injunction, the use of the Hammond spindle only was enjoined. 54 Fed. Rep. 693. The opinions which have , been already written in this litigation state the history and the distinctive features of the invention, and contain the conclusions' of the court in regard to the patentable character and scope and the proper construction of the claims of the patent.'

The characteristic feature of the Atwood invention was truly said in the specification of the patent to be “a supporting tube, which is flexibly mounted with relation to the spindle rail, and contains the'step and bolster bearings for the spindle, so that the latter and said tube may move together laterally in all directions during the self-adjustment of the spindle while carrying an unequally balanced bobbin and its yarn, instead of relying upon the movement of the spindle and its bearings within and independently of the supporting tube, as heretofore in this class of spindles.” In the prior suit, the Rabbetli spindle support, which was patented by letters patent No. 227,129, and which was admitted to have priority over the Atwood invention, was relied upon as an anticipation of the Atwood patent. The Rabbeth structure was described in the opinion as follows: It “had a supporting tube rigidly connected with the rail; a bolster bearing, which was a thin tube, affording a lateral bearing surface for the spindle; a yielding cushion between .the bolster bearing and the supporting tube, and a step bearing within the supporting tube. This tube may constitute the step bearing, but the step bearing and the •bolster bearing are separate pieces, and consequently the spindle and the bolster bearing can vibrate in all directions.” ■ The important features of the patented device were said in the same [655] opinion to be “the supporting tube, within which are formed both the ate]) bearing and the bolster bearing, and flexibly mounted upon or in relation to the supporting rail, the tube moving out of position under the influence of the vibration of the spindle; together with the manner in which the tube is secured to the rail, so that graduated pressure can be given, and strength can be secured.” It was further said that the flexible support, of the Atwood tube below the rail is far more than a change of the position of the Kabbetli cushion from the inside of his tube, and Hint the result was to cushion, but the method by which the cushioning is produced is very different. It is insisted in the argument of the present ease that the foregoing description of the Kahbeth device is not universally true, but that the patent also describes a method of construction in which both step bearing and bolster bearing are parts of the same thin tube, which the patent designates as a vertical bearing. Two of the three claims of the Rabbeth patent call for- a bolster bearing which is capable of yielding laterally with equal freedom in all directions, and a step within this supporting tube, which permits the foot to move in the same manner. These requirements are not expressed in the third claim, but, the whole drift of the specification is that the bolster and the foot of the spindle each has equal freedom of motion in every direction, and (hat the foot of the spindle is not confined laterally, but, is in an unsocketed or loosely fitting bearing. For example, it is said:

"In operation it will be seen tlxat the entire hearing-, f, [the vertical hearing-,] being- callable of more or loss lateral movement in all directions, and the foot of the spindle being also equally free to move in any direction, the spindle can readily assume any position which an unevenly balanced bobbin would cause it to assume.”

The position of the defendant is based upon the clause of the specification, which says, in substance, that when the bottom of (he supporting tube is fitted for a plain step bearing the vertical bearing is ojien at its bottom, and when it is desired that the bottom of the spindle be elevated above the bottom of the supporting tube the vertical bearing is mounted upon a base lube, which rests upon the bottom of the supporting tube, and the step bearing is provided for either by means of a head inserted in the bottom of fhe vertical bearing or in the top of the base tube. The defendant naturally supposes that “inserted” means fixed in the bottom of the hearing. I think that this is true, and that the thin tube can in one proposed method of construction contain both bearings, and to that extent the previous description of the Rabbeth device requires modification.

This fact does not change the patentable relation of the two dm vices to each other. It is admitted by the learned expert for the defendant that he does not find in any structure before Atwood's a live spinning spindle supported within a supporting tube, containing step and bolster bearings for the spindle, which tube is flexibly mounted with relation to the.rail of the spinning ma[656] chine. The flexible attachment, with relation to the rail, of this supporting tube, is the gist of the Atwood device, and was its substantial improvement upon the rigidly held supporting tube of the Babbeth spindle, and its cushion interposed between the supporting tube and the thin tube which constituted the bolster bearing.
