TABULATING ATTACHMENT FOR TYPEWRITERS.

Specification of Letters Patent.

Patented June 28, 1921.

Application filed November 20, 1919. Serial No. 339,463.

To all whom it may concern:

Be it known that I, MARVIN (irARRETT, a citizen of the United States, residing at Pensacola, in the county of Escambla and State of Florida, have invented certain new and useful Improvements in Tabulating Attachments for Typewriters, of whlch the following is a specification.

My invention has for its object the provision of a tabulating attachment for typewriters which will be efficient in operation and easily manipulated and which may be applied to a typewriter at a cost which is not prohibitive. The invention seeks to provide a tabulating attachment by which a form containing any number of columns within the capacity of the typewriter may be filled without requiring a separate adj ustment of the tabulator after it has once been set. A further object of the invention is to provide an attachment which will adapt the typewriter to a variety of forms without requiring the removal and replacement of the attachment or readjustment of the same, and a still further object of the invention is to provide a tabulating attachment which may be easily set to accurately arrange statistics in columns. The stated objects and other objects which will hereinafter'appear are attained in such a mechanism as is illustrated in the accompanying drawings, and the invention resides in certain novel features which will be particularly pointed out in claims following a detailed. description.

In the accompanying drawings, I have illustrated a portion of an Underwood typewriter, indicatedat 1, having my tabulating attachment applied thereto, but it is to be understood that this showing is for convenience of illustration only and is not restrictive in any way inasmuch as the attachment may be applied to any standard make of typewriter without substantial change in form or construction. The typewriter frame illustrated is provided at its back corners with posts 2 and. in carrying out my invention. 1 mount in the said posts the ends of a rock shaft 3 which may slide as well as rotate in the 'said posts and constitutes the main member of the stop bar carrier. Standards -.l and 5 rise from this rock shaft 3 at intermediate points of the same and the stop bar 6 is supported upon the said standards. The standard 4, as shown most clearly in Fig. 4, is provided at its upper end with a crosshead 7 disposed obliquely with respect to the rock shaft 3 and provided at its extremities with upstanding lugs or stops 8 while the standard 5 is constructed at its upper end with a crosshead 9 disposed at a right angle to the axis of the shaft 3 and in the same horizontal plane with the crosshead 7 but the said crosshead 9 is provided at its front end with an upstanding lug 10 from which a retaining'plate 11 extends rearwardly to overhang the crosshead and rest upon the upper surface of the stop bar when the parts are assembled. The rear end of the crosshead 9 is free of upstanding projections, as shown clearly in Fig. 4, but upon the said crosshead, near the rear end thereof, Ipivotally mount a latch 12 having an upturned hook 13 at its rear end adapted to engage the rear edge of the stop bar so as to retain the same in position upon the crosshead. This latch is constructed with a depending handle or finger 14 against which a spring 15, secured to the standard 5, bears so that the latch will normally be held in its upper position. The stop bar is preferably oblong and rectangular in plan view but its upper surface is arcuate or convex, as shown at 16, except at the end engaged by the retaining plate or keeper 11, said convex surface being formed on an arc concentric with the rock shaft 3 so that when the stop bar carrier is rocked the surface of the stop bar will remain in constant relation to the counterstops, as will presently appear. The stop bar is of such width that its front and rear edges will fit respectively against the front and rear lugs 8, as shown in Fig. 3. and in the front edge of the stop bar near the left hand end thereof I form recesses or notches 17 and 13 which are respectively adapted to engage the lug 10 at the front end of the crosshead 9, the purpose of which construction will hereinafter appear. In placing the stop bar in position it is first disposed obliquely relative to the rock shaft 3 so that its right hand end may be passed between the lugs 8 after which it is swung around so that its left hand end will ride over the latch 13 and onto the crosshead 9, the notch 17 or the notch 18 engaging the lug 10 and the latch 13 springing up intoengagement with the rear edge of. the stop bar to lock the stop bar in position upon the carrier. \Vhen it is desired to remove the stop bar for any reason, pressure is applied to the finger or handle member 14 to overcome the spring 15 and release the latch whereupon the stop bar may be readily swunggearwardly about the standard 4 as a center and withdrawn from between the lugs 8 as will be readily understood.

The stop bar is capable of both a rocking and an endwise sliding adjustment and these adjustments are effected through manipulation of a key at the front of the typewriter and adjacent the right hand side of the bank of typewriter keys. Depending from the rock shaft 3, is an arm 19 having a crank 20 at its lower end extending toward the right hand end of the haft. This arm 19 is shown as alined with the standard 4 but it will, of course, be understood that the exact position of the arm is not material and it may be disposed at any point where it will properly perform its allotted functions. Se cured to the side of the typewriter frame at the bottom thereof are a pair of brackets 21 and a single bracket 22. The brackets 21 consist each of'a bar having openings 23 therethrough and provided at one end with an upstanding lug 24 through which a. fasstood that as the bar 25 is slid forwardly or baclm'ardly the crank 20 will be set in motion and the arm 19 correspondingly swung so that the shaft 3 will be rocked to set the stop bar in a desired position. The front end of the sliding bar 25 rests upon the bracket 22 which is substantially U-shaped, having upstanding lugs 29 at its ends, and upon the outer side of the bar 25 is formed a rack 30, as clearly shown in Figs. 5 and 8.

The front end of the bar 26 also rests upon the upper surface of the bracket 22 and the lugs 29 at the ends of said bracket serve as guides for the slide bars in the, operation of the same, the outer lug 29 also furnishing means whereby the bracket may be secured to the frame of the typewriter. The bracket is provided midway its ends with openings 31 either of which may receive the lower end of a stem 32 depending from the key 33, the openings being separated by a web 34, as clearly shown in Fig. 6. A hinge bracket 35 is secured to the front of the typewriter frame and a lever plate 36 is hinged or pivoted to said bracket, as. shown in Figs. 5 and 6, the rear end of the said lever plate being provided with a vertically disposed sleeve 37 to receive the stem 32 and also having a llOI'lZOIltilLJlOtCh 38 to accommodate a pinion 39. vhich is manipulated by the sai'd stem It will be noted that the pinion is provided witha central opening having inwardly extending lugs 40 on its Walls and the key stem 32 is provided with channels or grooves 41 in its sides which are adapted to receive the said lugs whereby the stem may slide through the pinion but cannot rot-ate inde endently of the pinion. The sleeve 37 furnishes a bearing for the key stem and the pinion may engage the rack 30 upon the slide bar 25 or the rack 42 upon the inner side of the slide bar 26 accordingly as the lever plate 36 is swung to one or the other side. When the pinion is so engaged, the rotation of the key 33 and the stem 32 will cause the pinion to act upon the engaged rack and thereby slide the corresponding bar forwardly or rearwardly, as will be readily understood. The stem may be raised so that its lower end will clear the openings 31 when the pinion is to be shifted from side to side but after the pinion has been properly shifted, if the stem be lowered so that its end will engage in an opening 31, the desired rotary movement may then be imparted to the pinion without causing it to swing away from the engaged rack, and to further hold the pinion in the said adjusted position I provide a dog consisting of a leaf spring 43 secured to the under side of the bracket 22 at the front edge thereof and having a lip 44 at its free end projecting upwardly past the front, edge of the bracket to engage against the side of the lever plate 36, as shown in Fig. 7, and thereby hold it in the position in which it may be set. The form and strength of the spring should be such that it will normally hold the lever plate against movement but will readily yield when pressure is applied to the plate through the key 33 and stem 32. An index rod 45 rises from the slide bar 25 and is constructed at its upper end with a'pointer or finger 46 playing over an index plate 47 which is secured to the front of the typewriter frame adjacent the bank of keys and is provided with a forwardly and rearwardly extending slot 48 through which the said index rod may pass and in which it may play. A scale is displayed upon the index plate 47 adjacent the slot 48 and this scale corresponds to the number of longitudinal rows ofstops provided upon the stop bar 6 so that the numeral to which the index 46 points-will designate the row of stops which is in position to be engaged by the counterstop upon the typewriter carriage, as will presently be more fully set forth.

From the slide bar 26 an index rod 49 rises to pass through and play in a longitudinal slot 50 formed in the index plate 47 and upon the upper end of this index rod 49 is a double pointer 51 which at one end points to'the same graduations with which the index 46 cooperates and at its opposite end points to and cooperates with a scale indicating the denominations to which the stops have been adjusted. The slide bar 26 terminates adjacent the back of the typewriter frame and at its rear end is equipped on its outer side with a rack 52 which is engaged by a segmental gear 53 carried by the lower end of a vertical rock shaft 54 which is mounted in suitable bearings 55 upon the side of the typewriter frame At the upper end of the shaft 54, I provide a second segmental gear. 56, which engages a rack 57 formed on the front side of a setting block 58 which is fitted upon the rock shaft 3 and may be, in some instances, formed integral therewith. In the illustrated embodiment of the invention, the block 58 at one end rests against the standard 4 and at the opposite end against a collar 59 through which'a set screw 60 is inserted to bear upon the rock shaft and thereby secure the collar to the shaft so that while the shaft may rock in the block it cannot move endwise unless the block be likewise moved. Obviously. when the bar 26 is moved forwardly or backwardly the shaft 54 will be rotated and an endwise movement imparted to the block 58 and the shaft 3 through the operation of the segment 56 and the rack 57. To aid in holding the bar 26 in the position in which it may be set, a series of teeth or stops 61 may be provided upon the under side of the bar to be engaged by a. spring pawl 62 secured upon the typewriter frame or to one of the brackets 21 and a duplicate of this arrangement may be provided to hold the bar 25 against undue endwise movement.

To reduce wear, the ends of the pawls may be equipped with rollers as shown in Fig. 8.

In the operation of the device, a stop upon the stop bar 6 is engaged by a counterstop upon the typewriter carriage and to hold the stop bar and its carrier against movement under the shock of this engagement, I provide the rack 63 on the under side of the block 58 and also provide a holding pawl 64 to engage said rack or stop and hold the block and the carrier firmly against cndwise movement. The holding pawl 64 is illustrated in the form of a lever fulcrumed upon the typewriter frame and having its rear free end playing between said frame and a bracket 65, secured to the same, the rear end of the pawl forming a tooth adapted to readily enter between adjacent teeth of the rack 63 and securely hold the same. The front end of the pawl .is pivoted to a link (36 which has its lower end pivoted to a key lever 67 disposed between and somewhat above the

bars

25 and 26 and having its front end carried upwardly, as shown at 69, and terminating in a lip 69 fitting to the stem 32 immediately below the key 33 and above a collar 70 secured upon the said stem. The rear end of the lever 67 is fulcrumed upon the typewriter frame and the connection with the link 66 is in advance of the fulcrum so that, when the key 33 is depressed, the lip 69 will follow the movement and the key lever 67 consequently swing downwardly and pull upon the link 66 to rock the pawl G4,.the rear end of which will be thereby caused to engage the rack 63. The link 66 extends above the pawl 64 and has its upper end pivoted to a forwardly extending arm 71 on the front side of a combined brake bar and trip bar which is pro vided at its ends with trunnions orpintles 72 journaled in suitable bearings upon the. typewriter frame. This combined brake and trip bar is disposed upon th typewriter in advance of the rock shaft 3 and consists, in

the illustrated construction, of a flat bar 73 having depending portions 74 at its ends, the trunnions 7 2 extending from the lower ends of the depending portions 74 and the arm 71 projecting from one of saidv depending portions so that the trunnions form the center about which the several parts swing. A trip 75 issecured to and depends from the bar 73 and is provided at its lower end with a forwardly projecting lug or lip 76 which is adapted to bear upon the escapement trip lever usually provided upon the typewriter whereby when the bar 73 is rocked the typewriter escapement will be released and the carriage permitted to move. The carriage of the typewriter is indicated conventionally at 77. A leaf spring. 100 arranged between the arm 71 and the top of the typewriter frame holds the trip bar in.

its normal position and. returns it to that position after it has been rocked.

A rod, indicated at 78, is ordinarily found upon the carriage of an Underwood typewriter and, in applying my attachment to that make of machine, If utilize this rod as a support for the counterstops which cooperate with. the stops on the stop bar 6. .in open substantially U-shaped frame TS) is provided with ears 80 which are loosely engaged upon the said rod 78 between stop collars 81 whereby the frame may swing about but cannot slide longitudinally of the rod. A spring 82 is coiled around the rod 78 between the ears 80 and has one end secured to the rod and its other and secured to one of the ears whereby the spring tends to hold the frame away from the stop bar. A back plate 83 connects the cars 30 and from one end of said backplate a hanger 84 depends, a roller 85 being carried upon the rear side of said hanger 84l adj acent the lower end of the same in position to run upon the front face of the trip and brake bar 73 as will be readily understood and as indicated by the dotted lines in Fig. 11. The carriage stops or counterstops are mounted in the outer or rear portion of the frame 79 and are carried by a rod 86 inserted through the sides of the frame 79 and an intermediate web 87 disposed midway the sides and parallel therewith, the said web 87 serving to connect the rear end of the frame with a bridge plate 88 near the frontend thereof. Two counter-stops are provided, as shown at 89 and 90, and each of said counterstops is provided at its ends with lips 91, the rear lips being adapted to rest upon the rear end of the frame 7 9 while the front lips are engaged by leaf springs 92 which are secured upon the bridge plate 88, as shown clearly in Fig. 10. it will be readily understood, upon reference to Fi s. 10 and 11, that the springs 92 tend to liff the inner or front ends of the counterstops and thereby hold the outer or rear ends thereof lowered but will readily yield to permit the counterstops to pass over an obstruction and the rear end of the frame 79 forms a support for the counterstops and prevents them being swung downwardly to such an extent that they will not properly engage the stops. Each counterstop is also provided near its rear evtremity with a depending tooth 93 audit will be noted, upon reference to Fig. 1, that the said depending teeth have their under edges beveled in opposite directions, this arrange ment permitting one counterstop to ride over the stops and the other counterstop to engage the stops accordingly as the carriage is moving in one or the other direction. The counterstops are fitted loosely upon the pivot pin or bolt 86 and between each counterstop and the adjacent outer side of the frame 79 a cushion spring 9-1 is coiled around the said pin or bolt. If the counterstops were fixed upon their pivots, when either counterstop was brought into engagement with a stop it would remain in a fixed relation to the said stop so that wheirthe escapement mechanism was again operated the cou'nterstop would again be brought into engagement with the same stop and the carriage would not be permitted to move. T he arrangement illus trated and described, however, avoids this condition inasmuch as when the counterstop is brought against the stop it will yield slightly to the impact and the coacting spring 94 will be slightly compressed. As soon as the frame 79 rises to release the counterstop from the stop, the spring 9% will expand so that the counter-stop will then be projected slightly over the stop, and if it be then again depressed it will strike the top of the stop and will ride on the same instead of impinging against the end or side thereof as before. v

The stop bar 6 is provided with sockets or openings 95 in its upper surface which are arranged in longitudinal and trans erse rows, as clearly shown in Fig. 3, and it will be readily understood that any desired number of longitudinal rows may be provided but the transverse rows will be limited in number by the length of the line which may be printed upon the typewriter. These columns or rows of sockets will be numbered from front to rear or from rear to front of the stop bar, as indicated at 96, to correspond with the scale upon the index plate 4700- operating with the pointer a6. Stops 97, which are preferably in the form of a narrow plate having prongs 98 on oneedge, are

"engaged in the sockets 95 at such points as may be necessary to conform to the arrangement of columns to be printed and these stops will project above the surface of the stopbar so as to be engaged by the counterstop 89 or the counterstop 90 accordingly as the carriage is moved in one or the other direction. It will be noted that I have shown the stops'as provided with three prongs or teeth 98 which are to be engaged in adjacent openings in the proper column of tlie stop bar 6, the provision of a plurality of prongs or teeth preventing twisting of the stops from their proper operative positions. While I do not restrict myself to the illustrated details of the stop and the stop bar, it may be noted that the form of stop shown presents its edge to the counterstop and a thin stop will effectually withstand the impact of the countcrstop, and the same number of stops can be accommodated on a narrower bar than is feasible with the usual construction inasmuch as the stops are presented side to side transversely of the stop bar.

In the drawings, I have illustrated eight rows of sockets or openings extending lengthwise of the stop bar 6. The stops obviously may be engaged in the sockets at any point along any of the rows and by provid ing stops at several different points along any one row I adapt the tabulator to any one form upon which data is to be transcribed. ()bviimsly, therefore, the illustrated stop bar may be set up to accommodate eight different forms and it will not be necessary for the operator to change his machine or change the adjustment of the tabulator when his work involves the use of a variety of forms. It is frequently necessary to transcribe data into a plurality of different forms upon a single sheet and my attachment permits the operator to do such work without delay. It is also possible to provide for a large number of combinations of different forms inasmuch as the stop bar is readily removable and a stop bar having a different arrangement of stops may be quickly substituted for one which has been in use.

When the tabulator is to be used, the stops are engaged in the proper sockets of the stop bar so that they will conform to the arrangement of columns into which data is to be transcribed after which the key 33 is shifted to bring the pinion 39 into engagement with the rack 30 and is then rotated so that the bar 25 will he slid backwardly or forwardly. When the pointer 46 has been brought into alinement with the indicia denoting the proper column or row of stops upon the stop bar. the operator will know that the stop bar is then in such position that it will stop the carriage in position for printing in the first column upon the sheet and the successive stops upon the stop bar in the row indicated upon the index plate will cause the carriage to stop in positions to permit printing in the successive columns upon the sheet. When the bar 25 slides forwardly or backwardly, the standard 27 will be likewise moved and the shaft 3 rocked through the action of the crank 20 and the arm .19, as previously stated, and such rocking ot' the shaft 3 will bring the proper row of stops 97 into the path of the counterstops relatively fixed upon the carriage. After the proper row of stopshas been brought into the path of the counterstops, the pinion 39 is shifted into engagement withthe rack 42 so as to slide the bar 26 forwardly or rearwardly. The movement of the bar 26 will be transmitted through the segment and the shaft 54 to the segment 56 so that an endwise movement will be imparted to the

rock

89 and 90 which are shaft 3 through the rack 57 and the block 58. This movement of the shaft 3 will, of course, carry the stop bar 6 endwise and the stop 97 will be shifted relative to the decimal printing point so that the first character printed by the typewriter after the carriage has been shifted will represent a denomination corresponding to that indicated by the index 51. in the adjustment indicated in Fig. 8, the machine has been adjusted for use in connection with a sheet having an arrangement of columns corresponding to the adjustment of the stops in the fourth longitudinal row of sockets of the stop bar and to print the first character in any column in the position to represent ten thousandths if the notch 18 be engaged with the portion 10 of the keeper, or four spaces past the point for which the stop is set if the notch 17 be engaged with the member 10. After the stop bar has been adjusted, the key 33 is depressed so that the front end ofthe key lever 67 will be swung downwardly and a downward pull exerted upon-the link 66 which will swing the holding pawl 64 into engagement with the rack 63 so that the stop bar will be held firm and will not move under the impact of the carriage, and simultaneously with this movement of the holding pawl 6% the brake and trip bar 73 will be rocked forwardly so that the arm 84 will be swung forwardly and the counterstop frame 7 S) swung downwardly, the counterstops being thereby lowered into position to engage the stops. its the trip bar 73 swings forwardly, the trip 76 will release the escapement lever of the typewriter and the carriage will then at once more under the action of the spring drum in the. usual manner, said movement of the carriage continuing until one of the counterstops engages the first stop. The number to be transcribed may then be written, after which the key 33 will be again depressed and the carriage will move. until the counterstop thereon engages the second stop, the carriage being thereby brought into position to permit printing in a second column, and this operation may be repeated until all of the data has been transcribed. Obviously, the movement of the carriage is in the nature of a jump and. unless retarded, will tend to damage some of the parts under the shock of stopping. I, therefore, provide upon the type writer carriage a block or pad of leather, rubber, or other material, indicated at 99, which will be engaged by the trip bar 73 when the latter is swung forwardly to release the escapeme nt and the movement of the carriage will be thereby retarded so that the impact of the counterstop upon a stop will not be so abrupt as to cause breakage.

The stop bar will be held against endwise movement upon its carrier by the engagement of the lug 10 at the front end of the crosshead 9 in the notch 1'7 or the notch 18,

and either of these notches will be engaged accordingly as it is desired to stop the carriage before the stop 97 reaches the printing point or bring the carriage to a stop after the printing point has been passed. It will be understood, of course, that each longitudinal row of sockets upon the stop bar represents one form and that the spacing of stops in each row corresponds to the widths of the columns in the form represented by that row. It only one forml appears upon the sheet to be filled in, the stops may be ar ranged with one stop in each longitudinal row of sockets upon the stop bar so that the desired'adjustment oi the stop bar may be effected by manipulating the slide bar 25 and the slide bar 26 may remain at rest throughout the operation.

lVith my device the printing point may be at either side of the stop. The notches 17 and 18 are spaced aparta distance equal to nine printing spaces of the typewriter so that by shifting the stop bar in its carrier, the position of the stop, relative to the typewriter carriage may be shifted nine spaces. Referring to Fig. 5 of the accompanying drawings, it will be noted that the pointer 46 carried by the slide is opposite the numeral 4 upon the index plate and that the double pointer 51 is opposite the same nu- -mel'al and also opposite the legend l0 Thous The word legends on the index plate are read in connection with the pointer 51 only when lug 10 is engaged by the notch 18. Assume a stop 97 to be in the fourth longitudinal row of sockets in the stop bar and in the fortyfourth transverse row. that is 44 points or spaces from the beginning of a line of writing. If the key 33 be now depressed, the carriage will move and will stop with the printing point at are. Now, it the

pointers

46 and 51 be left undisturbed and the stop bar be shifted to bring the notch 17 into engagement with the lug 10, the step 97 will be shifted nine spaces to the left on the machine and the printing point on the paper shifted nine spaces to the right, the pointer 51 being then read in connection with the scale of word legends. In certain classes of work, it is desirable to be able to jump the carriage from zero to any point or space on the line scale without the trouble of setting the stops, and this result may be accomplished by putting one stop at 10 in the first longitudinal row of sockets in the stop bar, another stop at 20 in the second row, another stop at 30 in the third row, etc, the lug 10, of course, being engaged by the notch 17.

'If it be desired to jump the carriage to 24,

for instance, (twenty-four spaces from beginning of line) the key 33 will be manipulated so that the pointer 46 stands at 2 and the pointer 51 at 4 upon the index plate, after which the key will be depressed to release the escapement in the manner previously described. The notches 17 and 18 may, of course, be otherwise spaced and the range of the index plate correspondingly varied.

' My tabulating attachment is especially advantageous by reason of the capability of the stop bar to be adjusted longitudinally relative to the carriage of the typewriter and this advantage may be amplified by increasingthe number of notches in the edge of the stop bar so that instead of merely two notches arranged as illustrated and previously described there should be an extended series of notches arranged apart a distance equal to the spacing of the letters of the typewriter. It frequently happens that after the stops upon the stop bar have been set to correspond with the verticallines printed on'a form, the form will be inserted in the machine a few spaces to the right or the left of the exact position and it several carbon copies are being made it is very diiii cult to adjust the paper in the typewriter carriage so as to bring the printed forms into exact coincidence with the stops without disarranging the forms and as a result the writing on the-carbon. copies will be out of line with the writing on the original. With my invention, under surh circumstances. the stop bar may be shifted longitudinally the required number of spaces to the left or to the right so that the stops on the bar Will be brought into strict alincnient with the ruling on the form. hloreover, it is sometimes desired .to print a series of subtotals of a plurality of columns of figures without setting up a separate row of stops for the sub-totals and this end may be attained by simply shifting the bar longitudinally the required number of spaces toward the left after listing the several items and before printing the sub-totals. The stop bar carrier will, of course. be constructed with a lug or other stop of suitable form'to engage the notches in the stop bar.

It. will be readily noted that I provide for ,the adjustment of the stops to accommodate the arrangement of columns upon the form to be filled and also to eilcct the necessary denominational adjustment of the device through the manipulation of a single key and the same key serves to release the carriage to bring it into the printing position. it will be noted that the stop bar can be instantly released or removed from its carrier and another stop bar substituted therefor, and when in position upon the carrier, the stop bar will be effectually held against endwise movement relative thereto so that the action of the typewriter will be positive and certain, and it will also be noted that the device will operate with equal facility Whether the carriage is moving in one or the other direction and, consequently, it the work is such, that an equal number of entries is not to be made in all of the columns, the carriage may be moved past those columns in which no entries are to be made and need not be returned entirely across the frame of the machine when no data is to be put in the first column. The device is not complicated in its operation nor in the construction or arrangement of its parts and it is, therefore, not liable to get out of order and will prove eiiicient in use at all times.

It is to be understood that I do not limit myself to the exact construction and arrangement of parts shown in the drawings and herein described inasmuch as various changes may be made in the details without involving any departure from the principle or scope of the invention as the same is defined in the appended claims.

Having thus described the invention, what is claimed as new is:

1.
