invention which may be usefully employed in machines which do not'contain recording mechanism. Therefore, we do .not restrictor limit ourselves to 'use of thefinvention in connection withf'recording' mechanism,- except in such of the jappended claims asjim elude recording im'echnnism as subject-matter claimed in such 0 aims.-'
For convenience of illustration- "and description, we have shown the invention e'm'' bodied in an adding machine of the Dalton type which, comprises recording mechanismi for listing items or numbers which are in volved in the calculations or additions performedby the machine. I
It sometimes occurs that in operating add-- ing machinesto list or to add a s'eriesof items, one or more items may be erroneously listed and added or included in the calculations performed by the'niachinei instances the'item o'r items included throu h error may besubtracted, thus correcting t e error. Ourpresent invention comprises; mechanism for simplifying the operation of correcting errors, and in case the machine comprises recording i er'zl'ianism, it is desirable to designate the item or items subtracted so that it may be known at a glance that such items are" not included in the calculations listed, but that such items were listed through error and were subsequently corrected.
An object of the present inventionis to provide mechanism of the character and'operablc to perform theresults and functions art of the designate the subtracted-items and to pre- In suchabove mentioned, as well as other desirable results and functions appearing from the following description taken in connection with the accompanying drawings. in which Fig. 1 is a side elevation of a Dalton adding machine containing our present invention, the case of the machine and a few of the shafts and frame parts being in section. Fig. 2 is'an elevation showing the (am? nections for 'printing'a'designating charactor to designate the snbtrahend items and for controlling the adding raid; in un'itsorde'r to add 1 in units order as required to c'om plate the complementary number'tor'enderj the operation of subtraction 'properl" In this: view of the drawings the mechanism" is shownin idle position.

f'Figfishows an example 'of the work in: subtracting that may flie "performed by} the machine. f
The Dalton adding machine in which we have s'hoii'n the invention comprises differential mechanism 1 in which the numbers are set upby operationof the numeralkey levers 2 in the 'usual manner. After each number has been set 'upfi'n the differential mechanism the type-carriers 3 and their associated'racks 4 are operated in the well known way to list or'print the numbers onpaper, andto introduce or add the numbers:
in the adding mechanism 5 'The type sup-'' ported: by the type-carriers are driven by appropriately mounted hammers'fi'w-s re' quired to list the numbers 'on the paper. The hammers are pivotally supported upon a shaft 7 and are driven against thetype;
at the proper timeby springs- 8, provided for thatvpurpose. Eachhamti'ier is formed with a latch arm 9 arranged tobe engaged and held in a retracted position 'by a'hook 10 on a releasable latch member.
The latch members also havearms 11 which are engaged by projections 12 on the type-carriers with which said latch members, respectively, correspond when the type-carriers are at rest in their normal or idle positions. Thus the latch members for the hammers are held in their lower positions in opposition to the tendency of their springs 13 to raise the rear ends of the latches. When any one or more of the typecarriers are moved to recording position the projection 12 on such type-carriers as move to recording position are carried away from and out of contact with the arms 11 of the corresponding latches; thus permitting such latches to be raised by their springs 13 n sufficient distance to place the shoulders 14 on the raised latches in front of a latch release bar 15.
The latch release bar 15 has one end pivoted upon a stationary support 16 and its opposite end connected with a lever 17 beyond the opposite side of the series of latches so that said latch barextends entirely acrossan d above theseriesof latches.
The lever 17 is pivoted upon a-support 18 and has an arm carrying a rollerll9 operating on a cam 20. The cam 20 is supported from the main shaft 21 of the machine and in idle or rest position-holds the lever 17 1 actuated rearwar in the position in which the bar 15 is above the shoulders 14 on the latches; so that the shoulders 14. cannot engage in front of the bars 15. The up erendof-the lever 17 is d lyby a. spring 22 and in the normal or idle position-0t the machine said lever is held in its forward position above the shoulders l tby the cam.20 in op osition to the spring 22. y a
or present purposes it is suflicient to know that the main shaft 21 ofthe machine is turned in a forward direction after each number is set up in the difl'erential mechanismin order to permit the proper typecarriers to advance I to proper recording position. Such forward turning movement of the shaft 21 advancesthe; cam 20 to position to permit the spring'22 to move the upper end of the lever 17' rearwardly as required to move the latch release-bar 15 rearwardly a suflicient distance to permit the shoulders 14 of the latches whose type-carriers have advanced to rise in front of the latch bar. After the shaft 21 has completed its'forward turninglmovement, it is turned rearwardly to its starting point, thereby causing the cam 20 .to operate the lever 17 which movesthe latch. release bar 15 forwardly thusdisengaging the latches which had been engaged withsaid latch bar from their corresponding hammers, and permittingthe hammers tobe operated by their springs 8 as required to drive the type to print.
-When it occurs that any-item hasbeen erroneously listed and included within the addition or calculation and such error is not discovered until after the completion of the listing and calculation operation of the machine such error may be corrected. In such case; the complement of the number erro neously listed and included within the addition's'an'd calculations is introduced into the differential mechanism of the machine by operation of the complementary numeral keys; with the exception that the digit in units order lacks 1 of being of sufficient value, and with the further exception that the in the higher numerical orders above the highest numerical order of the subtrahend need not he struck on the keys but will be automatically introduced into the calculation.
-To effect the automatic introduction of the.9s for; the purpose mentioned the usual abutment plate 23 is depressed out of the way of; the shoulders 24 on the racks 4. The mechanism included in the machine shown for depressing the abutment plate 23 and with which our invention is cooperatively related. comprises a lever 25 operable by a link 26 to depress. the abutment 23 in any position of the differential mechanism. The forward end of the link 26 is connected with a lever 27 supported on a rock shaft 28which is connected up with the mechanism. comprising our present invention. The lever 27 supports a bifurcated member 29 embracing-the latch release bar 15 between the arms thereof and arranged to stop rearward movement of said bar 15 to prevent said bar from moving far enough to permit the shoulders 14: to engage in front thereof. The construction and arrangement inthe machine shown is such that the latch release bar will not release hammer latches when the mechanism ofour invention is operated. This prevents the printing of the complementary number in the process of subtraction, but permits functioning and operation of our invention to obtain the desired result and to print a designating character adjacent to the subtrahend number.
The Dalton adding machine also includes springs 30 for operating the racks 4 in transferring operations.. When said racks are not operating in transferring operations they are stopped in their normal or idle positions by lugs 31 thereon engaging the hooked ends of abutments 32 which are raised by the adding pinions in the usual manner in transferring operations. The transferring operations in the Dalton adding machine are well known and do not require further description. Our invention comprises means arranged to operate at the proper time to raise the abutment 32 in the lowest or units numerical order to permit the rack which operates the units .adding pinion to move rearwardlyas though a transferring operation was taking place in connection with the Inn number or total that had previously been set up or represented in theadding mechanism. This means we-will nowdescribe. 7
As shown, the subtraction controlling device or keycomprises a key 33 upon an ap propriately formed. lever 34 pivotally mounted upon a shaft 35. The key lever 34 is held in its raised position by" an appro v priatelyrOnnected sprin 36. The subtracting key lever is hBldlILltS depressed or operative position as long. as required by a latch device comprising a projection .37 .on the lever which engages under ashouIder 38 formed on a latch member 39 when the' lever is in its depressed positiom A. spring 40 connects the, key lever 34 vwith the pivoted latch 39 so as to cause proper releasable latch engagementbetween said parts when the key lever is depressed.

We will now describe the means bvfwhieh the full complement of the jsubtrahend is utilized to correct the error resulting froni entering into the calculation and listing the erroneous item. a I a In the example sh 'wnin Fig, the item 2457-was entered'intQ the calculations and listed through error. 7 This item should not have beenentered into the calculations and should not have been listed. In order to correct the error a nd remove this item from the calculations the complementnumber for the number 2457, less 1,i's set :upinthe difi'erential mechanism in the usual "way,
' after which the key lever 34 isdepressed and latched in its vdepressed position, following which operation the machine is operated as though an ordinaryitem was being added and listed. The complementary number of the number 2457, less 1, is 7542, and therefore the number 7542 is set up in the differential mechanism. After the complement number has been set up in the differential mechanism the key lever 34 is depressed,
causing an arm 44 on said lever 34 to raise an. arm 45 which is attached to a rock shaft 46 and which has a in 47 engaging the arm 44. The rock sha t 46 supports an arm 48 from which a link 49 leads to the lower arm of the lever 27. As a result of this construction the abutment plate 23 is depressed to permitthe automatic introduction of the 9s in'higher numerical orders in subtracting operations, as'above explained. It will be seen from the following description that the key lever controlling the addition of 1 into units order also controls the introduction of the 9s in the higher numerical orders.
As previously stated. it is necessary to enter into the calculations in units order adigit which is the full complement of the digit in units order in the error item. That is, it is necessary to enter into the calculation inunits order a digit which added to the digit in units order in the error makes 10, soa s to transfer 1 from units order to tens order, and transfer 1 from tens order to hundreds order,'and transfer 1 from hundreds ordert'o'thousands order, and so on throughoiitjthe full capacity of the machine which,
mentary to the error, lacks 1 in units order (if-being the full complement of the error niliilber 2457. To complete the full complementourinvention comprises means for addingglinto units order automatically and as an incident to operationof the machine in a subtracting operation, so as to make a full complement of the error number.
,"'In"order: to permit the transfer of .1 into units order inaddition to the digit set up in units. order in the complement number, as required to complete the full complement, theiabiltme'nt 32in units order is raised from theusual position shown in'Fig. 1 to permit the units rack to move rearwardly as though a transferring operation was taking lsce from'alower numerical order, as in case ofaddition of fractions, in an example. of addition. The device for raising the abutment '32 forthe units rack comprises a'lever 5Q pivoted on a support 51 and havingya projection 52 extending under the abutment 32 cooperating with the units rack Inforder to raise the abutment 32 controllingthe rackin units order, it is only necessaryto operate the lever 50. For this pru'pose wc provide an actuator 53 which, in case the invention is employed in an adding, calculating and recording machine, may be the type-carrier used to carry special typo for printing designating characters such, for instance, as a character for designating items thatlhad been listed by error. As shown, the actuator 53 isa type-carrier and a special type 54 for printing a designating character, andarranged to be driven by a special one of the hammers 6. The actuator 53 su ports a projection 55 which may be cause to engage with and operate the lever 50, as required to raise the abutment 32 controlling the units rack. The actuator 53 is held from functioninowhen the machine is being' operated in ordinary adding and call culating operations, not involving subtraction or other special operations. For preventing cfi'ective operation of the actuator 53 a projection 56 is provided on said actuator and arranged to en age a shoulder 57 on a pivotaily supported stop member 58. As shown, Fig. 2, the projection 56 and the shoulder 57 are arran ed 'relative to each other in order to permit slight movement of the actuator 53 which. in the form shown, is a type-carrier. Provision is made for this movement in order to permit the type-carrier to move far enough to place the up "1-- inost type thereon in proper position iela We to the printing line. Such movement is illefiective to cause operation of the; levi 50. In order to cause operatio'ii of the lever 50, as required to raise the a 'ut'nientBB'in units order,- it is necessar to more th stop member 58 to place a shoulder 59 on said stop member in position to he engage "y the projection 56. Siic'h movement of the actuator 53 is "sufiicint tb; cause the projection 56 to operate'the levi fig, resulting in the raising of the ahiitineiit 32in units order and permitting the reek in uiiitsoider to be moved rearwardlyby its spring. 30 a distance sufficient to trainsfer 1 into units order. This will complete the introdustion into the calculation of the full complement of the item that had been erroneously entered into the calculation and listed. v
The stop member 58 is moved to adjusted position to permit movement oi the combined type-carrier andactuat-or 53 to trip the abutment 32 and to position the proper. type for printing a designating character adjacent to the erroneous item as an inident to operation of the key lever 34. a'rin ($0 in connection with the key lever? extends behind a projection til-on a link 62 so that when the key lever is operated the iii! will be moved in a forwfard direction. T e forward end of the link 62 is supported by a pin-and-slot construction 63- and the real" cnd of said link is pivoted to a depending" arm in connection with the stop lnenib'ei tis. The stop member-58 is thereby operated to a position in which the shoulder 59 isjn ,t '0 line of movement of the projection thus. permitting the actuator and type-carrier 53 to move to the position sheen in Fig.3. When the key lever 34 is released from the latch member 39, as above ascribed, iiud re: turns to its normal position, the link sailed the stop member 58 are returned to' their normal positions by a s ring 64. a
As before stated, th latch release bar amen 15 during this operation is held in position to prevent the'shoulders 14 on the hammer latches from rising in front of the latch bar by means of the bifurcated member 29. However, the bifurcated member 29 does permit the latchbar 15 to move a distance sufficient to permit the shoulder 65 on the special latch which coo crates with the type-carrier 53 to rise in out of the latch bar 15 when a subtracting operation is being performed. The cam 20 in its return movement then actuates the latch bar 15 a distance 'siifiieient to release the special latch from the hammer 66 coo eratin with the type 54, thereby driving t s special ty 2 54 to print the designating character 67, s iown ig. 5, adjacent to the subtracted item which had been listed and entered into the calciilationsas a result of error.
From the foregoing, it will be seen that our invention completely serves its intended purposes, and that its cooperation with the i g'iilar mechanism of the fnachine is simply ahdeasily effected. We esteem platesn'ch va'riatidas i the inventian as may be necessary to. adapt it for difi'erent of machines, and we do not restrict our selves as a' essential {snares or limitations.
