To all 'who-m. 'it may concern.' i
Be it known that I, JAMES L. DALTON, a citizen of the United States, residing atv Pop- Alar Bluff, Butler county, Missouri, have in-v vented a certain new and useful Adding and ,Recording Machine, of is a specification.
This invention relates to adding and recording machines, and more particularly to machines of ,cross-carriage type such for instance as thatshowxi in an application of Hubert Hopkins filed-January 24th 1903-, Serial No.4140,390, eventuating in No. 1039130, dated September 24, 1912.
mechanism whereby two or more separate totals may be carried in the machine'at the same time. j 'i The .total mechanisms whereby the separatey totals are computed and. carried co operate with recording mechanism operable to record the items'including in the totals and also operabletorecord the totals and to clear the` total mechanisms, or permit the latter to retain the totals therein as sub` totals to be included in a iinal grand total. Other objects'and manifold advantages 'of the present invention will become apparent from the following specification, Areference being nade-to the iaccompanying draw` .ings in which: l

p1ate,-in which' all of-thev typeicarifiers are free to move to perform .tlieir jrecording functions.
The machine as at presentwillie-market includes a key-board on which-the keys-1 are arranged inconvenient manner in transverse rows, thel stems ofpthe v.keys-extending through slots in the Vkey-board .plate-and being connected with, or formingpart o f the key-levers Q, which project rearwardly and converge at their rear ends and aregprovided with vertical extensions 3 arrangedhin the same vertical plane. Two transverse rails l are supported near the rear end ofthe machine and the carriage 5 isl providc-djvith rollers G operating above said rails.
gages under one of the rails and thereby prevents derailment of the carriage 'during operation and during movement and 4transportation of the machine. .lVithin the carriage 5 the vertically movable pins 8 are upwardly and at the same time the carriage 5 will be moved one step toward the left A hoolt 74 attached to one side ofthe carriage cn- F ig. 15 shows the -lower position'p thestopwhich is sutiicient' to position the second row of pins in said carriage above the termini 3. This leftward movement of the car- Acal shaft 11, andzthe gear segment 12 on the yupper end of -said shaft 11 enmeshed with a rack13 rigidly connected to one side of the 'far'ria e 5. The escapement 9 has a lbar 14 exten ng over the key levers 2 whereby the eseapement will'be operated at ea'eh operation cfa key. In this way by successive operations of the-keys any number may be set up or registeredin the carriage 5, the pins 8 beingfpositioned to represent the digits of anumber. After the number has thus been represented in the carriage, such number may be recorded and added.
The recording-mechanism comprises a series of type-carriers 15 vswinging from a shaft 16, said type-carriers being arcuate in Aform and extending forwardly. On the forward end of each typ-carrier is a series of type.17,vsaid type 'lining movable with respectfto the type-carriers. A' platen 18 is ,attached on a shaft 19 mounted in a carriage 20 and is operable in connection with the feed rolls 21 to feed the paper across its front surface where records may be made by driving. the type 17 against an interposed ink ribbon. Coperating with each type-carrier there is a member 22, said membor swinging from the shaft 16 and provided on their lower ends with arcuate racks 23. ASaid membersi22 have .extensions connected by pin and -slot connections 24* with the t pe-carriers 15 so that each type-carrier to the length of its slot. The racks 23 are spaced apart the same distance as the-space Aseparating the rows of 'pins 8 in the carposition of the parts, the plate 25 is under the racks 23 and the rear edge of the plate is' supported immediately in front of the heels 24 so that when type-carriers and racks are-actuated forwardly, their forward movement will be stopped by the. heels 2l coming into contact with the rear edge of the plate In the present instance, the arrangement is such that the four racks at the right relative to the operator will engage with as independent movement equivalent the lower portion of the plate while the five remaining racks will eng-ige with the upper portion of the plate When the carriage 5 is moved leftwardly as before described,the plate 25 is also transported leftwardly and at each step moves from in front of one of the heels 2l so that as many racks and type-carriers will be free to move` forwardly as there were figures in the nurnber set up in the carriage. `After the numl ber has been thus'set up in the carriage and the type-carriers .have advanced to their forward positions and been properly positioned by engagement of the heels 2l with the pins 8, the number represented by the type 17 atthe'printing line will be automatically recorded by a set of hammers 28 striking the front ends of the type. Return movement of the type-carriers and racks is effected by a rod 29 supported in front of .the vertical portions of the ltype-carriers and racks by arms 30 depending from the shaft 16, said rod being moved in any convenient'manner. Total wheels 3l are arranged to become enmeshed with racks 23 on return movement of said racks thereby to add the items after they are recorded.
After any series of items has been added,
the total represented in the wheels 31 may be recorded and said wheels restored to clear position or the total may be retained in' the wheels. The mechanism for accomplishing this result as embodied in the machines of the character referred to at present on the market, and as disclosed, for instance, in I the British patent to Hopkins, No. S51, of 1904, includes a totals recordingr key 32 having a steml projecting through a slot in the key-board plate and pivoted at its lower end tothe front end of a lever 33, the rear end of which extends under the horizontal arm of a bell-crank 34. A link connects the bell-crank 34 with a lever 3() pivotcd to a shaft 37 at. the rear oi the machine. Said lever 36 also projects above the shaft 37 and an arm 38 pivoted on thc shaft 37 coperates with the upper portion with the lever 3G to support a horizontal rod which will be swung forwardly whenever the total key is depressed. A cam plate ll-0 is mounted in the carriage 5 and is provided with an oblique slot 4l in which a pin on an extension of the plate projects. SV hen the total key is depressed and the rod 3) is swung forwardly, said rod will engage against the rear end of the cam-plate el() and push said plate fcrivardlv thereby drawing downwardly tbe plate 25 untiLthe lower portion of said plate at tile right ot the cut 27 is entirely below the hecls of the four racks at the right. This will permit said racks and the coiliera'ting type-carriers to move forwardly, the racks `remaining enmeshed with the total wheels whih the totals recording key is down and being 'stopped thereby. ln this-way the total con" tained in thefour Wheels at the right relaf- The'meclranism so f r described iscontained -i n"the machine as et present on ,the

By-mechzinisnr of this churiicter vin-ions kinds of work may be' performed on the machine. For instance, parallel columns of items muy be recorded simultaneously as shown at the top of`Fig. 2 and separate totals thereby may becarried in the machine at the same time and then recorded simultaneously. Again, one column of items may be recorded by the type-carriers at the right relative to the operator as shown at A in Fig. 2 and the total of such column recorded as shown at` B. Then this total may be introduced in the machine through the keys 1 and the carriage 5 and recorded as an item or sub-total in a column at the left of the column A as shown at C. Then other items may be recorded in the column A a total thereof recorded in the same column and this total again introduced into the machine and recorded in the column C, as item or sub-total, after which the total of the numbers recorded in 'the left hand column may be recorded as shown at D. A third specimen of the\work of which this machine is capable of performing is shown at the bottom of Fig. 2 in which two columns oi items are vrecorded simultaneously and the totals thereof recorded at E and F, respectively and the machine cleared. After the totals have been thus ascertained they may be again introduced into the machine and recorded in one column or other as sbowr at Gr making a grand 'total H. The machine may also be used to perform work of various other kinds, but vthe Specimens illustra-ted are sufficient to enable those skilled in this art to compre! hend the nature and. the purpose of the invention. It will be Iunderstood, of course, that the machine performing this work, may be split so that the ciphers at the 'right of the numbers in th'e left hand column or columns will not be recorded, thereby enabling the operator to list a single column of numbers on the left or parallel columns printed simultaneously, specimens of both of which are shown' in Fig. 2.
I am aware that' there may be lvariations' in the constructions, combination and arrangement of this invention Without the least departure from the spirit and scope of the invention. Also that the machine may be used to perform various classes of work other thanthose illustrated and l do not restrict myself to specific constructions or arrangement nor to specific functions, but what I claim and desire to secure by Letters Pateneis: g
