Opinion

BAKER, Circuit Judge.

Appellants, owners of patent No. 1,039,-130, which was issued on September 24, 1912, to Hopkins, for a combined writing and adding machine, sought unsuccessfully in the trial court to suppress an adding machine made by appellees under the Sundstrand patent, No. 1,198,487, September 19, 1916.

Claims to the number of 284 are contained in the Hopkins patent. [423]*423Of these 44 were insisted upon at the trial and are here under the assignments of error. Following the oral argument, an extended consideration of 1,983 pages of record and 528 pages of briefs, and examinations of numerous physical exhibits, have finally led to the view that all the issues in the case are to be disposed of by stating and answering one question.

Burroughs was the. founder of the adding machine art. His machine comprises, broadly, a setting-up mechanism, by which the operator positions stops to determine the numbers that are to be recorded and added ; a printing mechanism, by which the selected numbers are recorded on paper; an adding mechanism, by which the totals are accumulated ; and an operating mechanism, that sets in motion the various parts through which the addition is recorded.

As we are not herein concerned with the adding and operating mechanisms, we note that the Burroughs setting-up and printing mechanisms employ the following five elements, viewed broadly: A keyboard; a field of stops; a printing device; connections between the keys of the keyboard and the field of stops; and connections between the field of stops and the printing device.

The Burroughs keyboard contains nine rows, of nine keys in each. The bottom row is made up of l’s the next of 2’s and so on. In the other direction, beginning at the right hand, the rows represent the ordinal values of the numerals. (Separate provision is made for printing ciphers without the use of a key.) In the field of stops, the frame of which is stationary, there are nine rows of nine stops. When the operator depresses a numeral key, a stop of corresponding cardinal and ordinal value is set up in the field of stops by means of the interposed connections. When the stops representing the selected number have been set up, the operator moves a lever, which through its connections brings the type carriers into the positions determined by the set-up stops, and then a farther movement of the lever causes the printing to be done. The Burroughs printing mechanism consists of a platen, movable type, and hammers to strike the type; the paper being interposed between the type and the platen.

Prior to Hopkins many detailed improvements upon the Burroughs machine had been made. But no invention of a primary character appeared until the issuance of the Plelmick patent, No. 630,053, August 1, 1899. Helmick’s invention of the 10-key adding machine could not found a new art, but it exhibited a radically new start at a vital point in the older machines. No one has been able to get away from the field of 81 stops. That has remained as an essential means of placing the type in printing position. Burroughs used 81 keys and 81 connections to control the 81 stops. Helmick found that he could control the 81 stops with 10 keys and 10 connections. The 10 keys represent the cardinal values of the numerals; ordinal values are obtained by giving to the field of stops a step-by-step movement. When a key is depressed, the corresponding stop in Lhe foremost row is set up, and at the same time, by means of an escapement mechanism, the field of stops is moved to a new position, in which the row of stops containing the stop set up by the depression of the key is in line with the right-hand type [424]*424carrier, and the second row of stops is brought into operative relation with the keys. Successive operations of the keys result in repetitions of this movement, until the selected number has been set up in the graveling field of stops, when, by the operation of the lever, the type carriers are moved to the positions permitted by the stops, as in the Burroughs machine, and then the printing follows. In his printing mechanism Helmick did not employ the Burroughs platen, but interposed the paper between the hammers and the type.

Hopkins not only knew of the Burroughs and Helmick adding machines; he was also acquainted with typewriting machines. In his patent for a combined adding and writing machine, many claims, presumptively valid, are devoted to the combined operations. Claims relating to the setting-up and printing mechanisms of an adding machine are divided by appellants into four groups.

The first groupi, 20 some in number, covers all of the specific features which Hopkins developed in bringing together tire foundational inventions of Burroughs and Helmick. We assume that they are sufficient in number and scope to afford appellants ample protection against the unauthorized use of any of those specific features or their fair equivalents. And we accept appellants’ concession that the machine of appellee does not infringe any of these claims.

The second group, 20 in number, comprises various combinations of setting-up and printing mechanisms, in which the traveling field of stops is called a carriage, and is characterized by one of its functions. Claim 141, which is typical of this group, is as follows:

“The combination with,
“1. A series of type carriers;
“2. Hammers co-operating with the type on said type carriers to record;
“3. Means for causing said hammers to operate incidentally to the operation of the corresponding type carriers;
“Each hammer remaining idle when the corresponding type carrier is idle; and
“4. A carriage operable to select the number of type carriers which may be operated; of
“5. A paper carriage arranged to feed a sheet of paper to said type carriers; and
“6. Means for holding said carriage in different lateral adjustments to présent different, columns of paper to said type carriers.”

Terms of broader scope can hardly be imagined. But none of the elements, so generically stated, was brought into being by Hopkins. Elements 1, 2, 3, 5, and 6 were old with Burroughs and his improvers, prior to Hopkins. Element 4 in every generic sense was the property of Helmick.

The third group, 13 in number, is similar to the second group, except that it characterizes the “carriage” by another function. Claim 31, which is typical of this group, is as follows:

“In an adding machine,
“1. Backs;
“2. Type carriers in connection with said racks;
“3. A carriage whose operation is necessary before said racks and type carriers may be operated;
“4. Mechanism for operating said type carriers and racks;
[425]*425“5. Adding mechanism operated by said racks;
“6. Movable elements limiting backward movement of said racks;
“7. Trips operated by said adding mechanism for moving said movable elements effectively to release said racks; and
“8. Means for operating said racks effectively to transfer or carry from lower to higher orders in said adding mechanism.”
