Opinion

AESCHUEER, Circuit Judge.

The action was at law, begun by the predecessor of plaintiff in error for alleged infringement of certain claims of United States patent No. 1,336,904, to Hopkins, through the making by defendants in error of machines under later patent to Sundstrand, No. 1,198,487. At the close of plaintiff’s testimony, on'motion of defendants, the court directed verdict in defendants’ favor on the ground of noninfringement, and gave the judgment here in question.

Application for the Plopkins patent was filed April -9, 1906, and patent issued April 30, 1920. The Sundstrand application was filed March 14, 1914, and patent thereon issued September 19, 1916, and reissue patent No. 14,237 granted December 26, 1916. All the devices are in the adding or calculating marchine art, that of Hopkins being for a combined calculating and writing machine.

The Plopkins patent presents the disturbing situation of its pend-ency in the Patent Office for over 14 years, and the allowance of the appalling number of 421 claims. These facts, while not influential in determining the issues here, suggest the dire need of change in our patent law or practices, or both.

This controversy has to do only with the “setting-up” mechanism of the adding or calculating machine — the mechanism whereby certain stops are positioned for arresting the moving type-carrying bars in proper place for printing the desired, numerals. The Sundstrand applications were filed and granted during the pendency of the Hopkins application, and Hopkins, contending he was entitled to certain of the Sundstrand claims, in 1918 adopted, and on hearing of interference was allowed, claims 12 and 14 of the Sundstrand reissue patent, as Hopkins’ claims 419 and 420, which are as follows:

“419. In a stop mechanism for. adding machines, a stationary group of stops, a plurality of push pins, means for moving the field of push pins into position adjacent the various stops, and means for projecting said push pins against the stops.
“420. In a stop mechanism for adding machines, a stationary group of stops, a movable support, a plurality of stop-setting members carried by said [552]*552support, means for moving said support to carry said members into and out of operative relation to the various stops, and means for actuating said stop-setting members.”

These are typical of the six claims sued upon; the other four, 181, 182, 211, and 214, being somewhat more limited. On determination in Hopkins’ favor of the interference, Sundstrand disclaimed his reissue claims 12 and 14.

A prior patent to Hopkins, No. 1,039,130, September 24, 1912, on application filed January 24, 1903, for a combined writing and adding machine, was the subject-matter of an earlier controversy in the same District Court, wherein infringement of the setting-up mechanism of the first Hopkins patent was charged through the same Sundstrand setting-up mechanism as here in issue. The court found noninfringement, and entered decree accordingly, which this court affirmed. Dalton Adding Machine Co. v. Rockford Milling Mach. Co., 267 Fed. 422.

The very broad claims there in issue, sufficiently inclusive to cover the Sundstrand machine, were held, in the light of the prior Burroughs patents and the Helmick patent, to be limited to the mechanism which Hopkins showed, and not to cover the Sundstrand setting-up device. The Hopkins patent of this suit had not been issued at the time of the disposition of the other case, and of course was not before the court.

The question here is upon the infringement of the second Hopkins patent, and not the first. But the query presents itself: What is there in the setting-up mechanism of Hopkins’ second patent which requires here a conclusion different from that reached in the action upon his first ? Here, as there, Burroughs is the pioneer in the use of a stationary field of stops, actuated by 81 keys, and Helmick broadly the inventor of the movable field of stops actuated by 10 keys. Hopkins’ first patent (which is here prior art) shows also the movable field of stops in a 10-key machine. Por more detailed description and comparison of setting-up mechanism of these respective devices, our opinion in the Dalton Case is referred to.

Hopkins’ second patent shows a complete rearrangement of his stop mechanism, but when carefully examined does not really present a very wide departure from what he showed in his first, where each key, when depressed, elevated a' stop in the field and caused the carriage to move one step, presenting the next order of stops for action by the next depression of a key, and so on, and after printing the number the entire field to be returned to original position with all stops back to normal. In his second Hopkins has in effect split his field of stops into two fields, one over the other, the upper stationary and carrying the stop pins, and the lower a field of corresponding pins in a carriage slidingly mounted on a frame. The depression of the keys, instead of raising the stop pins themselves, raises pins in the lower field, and moves the lower field one order on each depression until the then elevated pins in the lower field are opposite corresponding stop pins of the upper field, whereupon the' influence of the key depression is terminated, and the movement of the handle lifts a pivoted frame carrying the lower field of pins, sufficiently to cause the then elevated pins in the lower field to press against the corresponding stop pins of the upper field, causing these particular stop pins to rise above the normal face of [553]*553the tipper field of stop pins and act as stops to the type-carrying bars which overlie them. The specification better states this feature in these words:

“From tbe' foregoing description it will be seen that, wben an example is introduced into tbe traveling carriage and tbe setting-up pins are elevated, tbe said traveling carriage bas progressed step by step under tbe stop pins 93, so that wben tbe completed item is set up on tbe keyboard tbe traveling carriage with its setting-up pins occupies tbe proper relation with respect to tbe field of stop pins; tbat is, if tbe example was 123, tbe elevated setting-up pins will lie directly under tbe pins in tbe hundreds, tens, and units columns in tbe field of tbe stop pins. Wben tbe frame 58 is elevated, tbe setting-up pins will elevate corresponding stop pins 93 and position stops for tbe rack bars in exactly tbe relation to eacb other that tbe setting-up pins occupied. Thus, in the example 123, tbe stop pins 93 in tbe hundreds, tens, and units columns will be positioned so as to arrest tbe rack bars in such position tbat this sum will be printed and registered in tbe totalizer wheels.”

Now, so far as the stop mechanism is concerned, if the lower movable field were extended upward, its pins, when elevated by the key compression, would serve as the stops, and do away, not only with the need of two fields of pins, but also with the mechanism for lifting the lower carriage and frame for elevating the stops in the upper field.

It is contended for plaintiff in error that this division into two members of the Helmick and first Hopkins movable field possesses the advantage of reducing the shock and strain present where there is but one such.
