` To all 'whom it mafyconcernr rendered and. accounts kept and for simplifyin the work lof the hook-keepers ofthe es ta ilishrnent. To this end l associate with the platen corresponding to the usual platen -of thev machine, a second and auxiliary platen. The two platcns fina-y .he actuated separately and independently of each otlur, and it is in this manner that they are' lc`- signed to. he utilised in connnercial billing,y Work. Means argshown, however, by which the two platens may he Aso connected that they may he actuated hy the usual and ordinary line-space mechanism ofthe machine to which myV invention shown as applied, and

when so coupled or coiiinected the two platcns may he uscd as one in a manner in no wise i different from that employed with the usual and ordinary platen ofthe-inachine.

One billing systenr'in which the two platen are used' 1n their separate -a11 l' .l1st1net caa'citics may be outlined. hricfly as follows :-v

. en a sale is made, a hill or sales slip contalnlng thefgltcms and amounts of the sale is made out hyl the sales clerk andgscnt to the Atthe end of 'oi'lce -of th'e establishment. the day the sales slips which have been received at the' oi'lice are divided into lots alphabetically', and lthe order in which cach lot or group isass'ortc'rl is thereafter maintained at all times. l 45 l -lng machine who totals all sales slips of each The various lots or groups-then pass into the hands of an'operator of an addcustolnen', with the adding machine and then prints the several totalsv upon a tot-Mining strip Vin said machine. 'l-hc totalswill appear on thc totalizing strip of the addingr Inachinc in the order in Which'the sales ,slips -arc kept.' The different lots of sales slips alphabetically grouped as stated are next turned v over to the' typewriter' operators who make from the sales slips the bills which are to be sent to the customers. Thus one operator will have, for example, the hills'of all custoniers whose naines he in with A, B, C or D; a second operator wil have the bills of all customers whose naines begin with E,l F, G or ll, and so on. The sales slips hein carefully maintained in the order in whic 1 they were.handed to the typewriter operator are used. as copies from which to write the bill.

f The latter is inserted into the machine so as to he fed over the long sectionof the platen or that section which may be said to correspond with the ordinary and usual platen of -the machine. At the same time that the first hill is inserted in the machine a separate and independent longv and narrow strip of paper is inserted in the machine, so -as to be fed over the Ishort section of the platen.

After the entry of the days sales on the i hill is completed the total arnount of the dayssales is written hy theoperator in the daily total column on the hill and thereafter this total amount for the day is Written on the narrow continuous strip on the short auxiliary platen.v lt will he apparent, therefore,vv

.that the totals on the narrow strip, which may be called the checking strip, will appear in the order in which the-typewriter operator" receives the sales slips and in which the entries are made on the bills. items have been written on it, the hill is filed away until the next sale is made to the customer to whoni the bill is made' out. This method is continued until the end of the lnonth when the monthly total is inade out from the, daily totals on .the bill, after which the latter may be given to the hook-keeper who makeshis entries from it, and thereafter it is forwarded to the customer. course is Apursued the condensed record carhon sheet usually employed may he dispensed with. At the end of each day the narrow checking or totalizing strip contain- `ing that days totals of the different bills is turned over to thc 'hoolekeeper for co1nparison with thc totalizing,r strip previously Inadeon the adding machine.

After the days VVheIL this By coinpar? the ratchet head 29 being formed with re` cesses or depressions 36 to receive said last named pins. The locking Pin 31 isl constantly pressed'inward by the force of a leaf s ing 37, the end of which is b'ifurcated so at the arms 38 of the bifurcation embrace tially 'surround the locking pin. The

or le' spring is secured to the face of the ratchet'wheelQQ by a headed screw 39.

The locking pinmechanisrn just described, when in operative position, as illustrated in Fig. 5, so connects the two platens that theyT may be ope-rated'by the usual and ordinary linefspaeemechanism presently to .be described, but yfor the main purposes of my in-A vention the locking Vmechanism is normally inoperative as shown in Figs. 2 and 3. To render the mechanism inoperative, as shown 4in these last named iigures, it is necessary only to pull the, locking pin outward ortoward the right against the pressure of the leaf spring 37 unti the pins 35'are disengaged from the recesses 36, andA thereafter to turn I the knurled head 33 of the locking pin until the said pins 35 are out of alinement with their recesses 36. Tlf now the locking pin be released, the ends of the 4pins 35 will abut against the face of the ratchet wheel 29, thus prventing the locking pin from returning to position shown in Fig. 5. The pins 35 are of such length that when they` abutagainst the face of the ratchet wheel 29, the

endof the locking pin 31 is wholly withdrawn from the perforation 32 in the end'piece 25, so that lthe two platens maybe turned sep arately and independently of'each other; It is to be understood throughout the specificationl that the locking pin mechanism is'in inoperative position, except where the contrary is specifically stated.

In the mechanism, as hitherto described, the ratchet wheel 29 serves the purpose of the usual and ordinary ratchetwheel found in the type of machine under consideration. .Engaging with the teeth of said ratchet wheel is a detent roller 140 which.f is mounted at the end of the spring finger 41, which is iixedly I secured to the rear bar 6 `of the platen frame i or carrier.

.lever 42 is pivoted at 43 to a lug 44 fixed to The usual form of line-space the platen frame, andV pivoted to the upper arm of said line-space lever at 46 is a pawl 47 which cooperates with the ratchet teeth of the ratchet wheel 29, and the throw whereof-may be .re ulated bya line-space regulator 48. AThe ine spacing devices are 4introduction of the bill n.,

the usual manner it causes the pawl 47 to engage with the teeth of the ratchet wheel 29 and to rotate the latter one, two or three teeth, as the case may be. As the ratchet wheel turns, it causes the sleeve portion 19 I on which it is mounted and thes'leeve 18 to rotate with it thereby rotating the main )laten 13 through a corresponding distance.

uring this rotary movement of the main platen 13, the auxiliary platen 22 remains quiescent. i

Suitably secured as by screws'49 tothe top of the front bar 6 of the platen frame are two. upstanding ears 50 which serve as bearings for the pivot portion 51 of an. auxiliary l-inespace lever '52. The 'line-space lever-comprises, in addition tc the pivot portion 51, a `linger portion 53 projecting forwardly in a general horizontal direction from the left- Ahand end of said pivot portion and a rearwardly projecting horizontal arm 54. Piv oted at 55 .to the end of the arm 54 is a depending pawl 56 which is ada ted to engage with' the ratchet teeth-28. vhe pawl 56is formed with 'a tail 57 which is normally pressed against a )in 58l projecting from the side .of the arm 54 .y a flat spring which is also secured to said arm 54. The rear or pawl arin of the auxiliary line-space lever is held normally depressed, as shown in Fig. 1, by ar coiled spring 60 which surrounds the pivot portion 5 1 of the lever, and one end whereof' is secured to the rear or paWl arm 54 of said lever.- A rollcrdetent o1 is mounted in a spring arm 62 which is lixedly secured to the rear bar 6 of the platen frame. The roller detcn-t 61 cooperates with the ratchet teeth 2S to' prevent accidental rotation. of the auxiliary platen. v

ln operation, thel 'll, which is indicated by the reference (his introduccil into the ma'- chine so as to leed over the main platen 13. At the saine time 4that the lirst of thel days series ol' bills is introduced into the machine, along, narrow strip of paper,.wl'iich has been previously rel erred to as a checking strip and which isindicated in the drawings by the reference/i, is introduced into the machine so as to feed over the shorter or auxiliary platen 22. (lonen-lering Athe bill u to be one well along in the days series vof bills, it is evident that when the said bill e is introduced into th'e'machine the checking stript will have printed upon it-a number ol daily totals, as

.indicated ifi-Fig. 4 ol" the drawings, and this 4number will be' thesame' as the number olf bills which have been written up prior to the As illustrated 1n the drawings, the bill (L isone showing a prior purchase made on Nov. 5th and ri-prcseuting a total for thatdato olfti] .51), which amount it is to be assumed Wasset Vdown inthe propel' place on the. checking strip ol Nov', 5th. rlhe Jill is fed into the machine in a Well-known manner, which l have not considered it 4nec- 'iary platen 22 one lin'e space.

The data is copied by the .operator from the sales slip in a manner well understood and which I have not deemed it necessary to eX- plain at length. Thereafter the lliuc-space ever 42 is actuated, causing the. pawl 47 to enga e with the ratchet wheel' 2l), and turning t e main platen 13 through a double line space, the line-space regulator-48 being so set as to give main platen, as indicated in Fig. l. During this rotation of' the main platen through two spaces, the auxiliary platen is maintained in a relatively fixed position or state of rest the'engagenient'of it's detent roller 40 with the ratchet teeth 28. The second line of the purchase of Nov. 12th, namelyg# 1 pr: lace curtains. 15.5()

is nex'twrttcn on the bill. Then the line space lever 42 is again actuated, the auxiL iary platen remaining motionless as before,

.appears in Fig. 4) it will be understood, is the 12th of the last precedingl dai total for Nov.

is made for the same aceountor until the end ol the month. .'lhcreal'ter the next succeeding bill is fed into the machine; the amount ol"4 the purchase of Nov. 12th is copied upon it from. the sales-slip .rela-ting. to said suc coed ing bill in the manner hitherto described; and the total amount ol` the purchase is rc- 'coljded in the daily total column of the bill, 'The auiilia 1 line-space lever is thereupon actuan-dao cause a rotary movement oftheauxiliary platen, thereby leediu f the checking strip the distance ol a sing; e line space and the daily'total is recorded under. the $90.50, which is the last amount on said that amount ol" feed-to the- 32, thereby locking or couplin -bined lengths. paper approximating 1n Width the length of land that said operatingl checking strip. until all of the days bil s have been written and their amounts recorded on the checking stri i, which latter is then turned over to the boo keeper for comparison with the adding machine totalizing strip, as has been eX- plained.

When it is desired to use the platen for ordinary work it is only necessary to manipulate the locking or coupling device g that is,

to turn the locking pin 31 by Ineens of its 75A head 33 until the. pins 35 aline with the recesses 36. When this position is attained the spring 37 pushes the locking pin inward. Either of the platens is rotated until the holes 30 and 32 are in alineinent and as soon as this 80V occurs the locking pin 31 will enter the hole.

the two platens together so that both wil rotateto ether when actuated either by the ordinary ine-space lever 4L- or space lever, or by the usual 'platen finger wheel 63. The axes of the two platens are coincident,aml said platens are equal in diameter and are so closely arran ed end to end that they allord a v)raetically cylindrical surface throughout their corn- ()ousequently, if a sheet of the combined plalcnsl be fed into the Inachine, it may be manipula-ted by the line spacing devices described and by the other devices vcommon to the machine and written upon as though the platen were one of the regular style.

It will be noted that the line space o erat,J

ing levers 42 and 52 are unequal in lengt the pon er arm of the lever being much shorter than the power arm of the operating lever 42 levers are actuated in op'iosite directions, pulled upwardly and the lever 52 being pressed downwardly. This arrangement is a desirable one as it tends to prevent confusion in the mind of the operator as to the line spacing devices and enables said line s paring devices to be independentl operated without one interfering Withthe ot er.

0l course, the platens herein shown and* described ma f be used for other systems of billing as well poses for which they maybe a plicable; and I do not wish to be considere( es limited to theI use of my novel mechanism for the specifi c purposes above described, inasmuch as it is' plain that saidr mechanism may be used 120 for a variety of purposes. vFor example,' 'where what `may be termed .the condensed record system is employed, the bill, as it is written is inanifolded paper on a cond'ensed rec-ord sheet which, after it is illed, is usuallyy incorporatcd with other sales sheets 1n a binder, which-'binder then constitutes a sales This process is repeated 65 by the auxiliary line- B5 continuous 90 the'lcver 42 being 105 as for any andall other pur 115 y means of carbonV .or sales book. Each regular customer of the estabarbitrary symbol and after the amount of his purchase.is recorded on the bill, the same amount is written on the chechimr or ledger strip preceded. by his arbitrary resignation or symbol. When all of the days sales have been recorded on the ledgerstrip, the latter is turned over to the book-keeper vali enabled, by means ofthe arbitrary symbols, to debit or credit the amountsto the proper parties .in his ledger.

Where credits are to' be given for cash or returned-goods, such credits may be entered lon the monthly bill sheet and on the checking or ledger strip in credit columns provided on said papers orsheets. l llhispartol' the account system has been omitted from the drawings `and specification in order to simplify the Apresenta-tion oi' the invention as much asl possible consistently with a clear description thereof.
