I haveshownmy invention, in the present instance, embodied in a #23 Remington bookkeeping machine and used in combination with features disclosed. in the application of Frederick A. Hart, Serial No. 120,- 403, filed July 3, 1926 and disclosed also in the joint application of Sigurd 'L. Walsoe and John P H L'Serial N lgn ag l a A still further object of my invention is to" 1926. Serial No. 122,239.

July 8, 1926. While from certain aspects of the present invention, features thereof are claimed in combination with other features invented by the said Frederick A. Hart and disclosed and claimed in his said application, nevertheless, from other aspects of my invention, the paper end stops, etc, are of eneral application and may be employe in various characters of typewriting and like machines, all as will hereinafter more clearly appear,

In the accompanying drawings, I have shown only so much of the #23 Remington bookkeeping machine, and the constructions disclosed in said Hart and Walsoe & Hill applications, as is necessary to arrive at an understanding of the its embodiment therein.

Generally stated, the machines of said applications are employed in various kinds of billing operations, where two or more work sheets are to be .correlated in the machine and printed at a single operation; However, I do not deem it necessary to describe specifically the many different forms ofbilling nection with which the machines may be employed together with the vices of my invention. I

.One method of using the machine which will be specifically referred to, is its employpaper end stop de ment', for example, by a public service corporation suchas, say an electric or gaslight company, for simultaneously, or at one writpresent invention in operations in which the said machines may ing, making out a bill, making corresponding entries on the ledger sheet carrying the account, and on a record or register sheet whichreceives the entries written on all of the individual bill and ledger sheets. In the example referred to theregister sheet and its accompanying carbon sheet remainin the machine. The ledger sheet which usually requires but a single cross line entry at a time, say, for the-month for whichthe entry is made, may be in the nature of a blank with different vertically ruled columns to be filled in under appropriate printed headings; each cross line of thesheet being ruled ofi' la zonta y d g n e r o a d fie e ma h,

and the entire sheet covering a period of anywhere from, say, eighteen to thirty-six months. Means are provided to enable each ledger sheet to be quickly introduced backwardly from in front of the platen and properly positioned to receive the requisite entries in the line allotted for the month in question without disturbing the previously introduced register sheet. Means also are provided for then quickly entering a bill sheet and accompanying carbon sheet rearwardly into the machine from in front of the platen, and accurately positioning them in proper correlation with the previously introduced ledgersheet and the printing line. The entries may then be made on the bill sheet and these will be transferred through interposed carbon sheets to the ledger and register sheets. If desired, additional entries may be made on the ledger sheet which are not to appear on the bill or register sheet. The bill and ledger sheets and accompanying carbon sheet are then rapidly withdrawn from the machine Without disturbing the register sheet, and another ledger sheet and a bill sheet with accompanying carbon sheet may then be quickly introduced as before, and so on. I

In the example of the billing operations explained above the end stops of my pres"- ent invention are intended to coact with the ledger sheet, to quickly and accurately eflec't a positioning thereof under varying conditions. It should be understood, however, that in other uses of the machine, the said stop devices of my invention will coact with other sheets in a variety of ways, some of which will be hereinafter explained.

With the foregoing general explanation, I will now proceed to briefly describe so much of the said Hart machine as is necessary to arrive at 'an understanding .of my invention in its embodiment therein.

The frame of the machine is of the usual construction .and includes a top plate 1 carrying fixed guide rails 2, oppositely grooved to receive crossed anti-friction guide rollers 3. These rollers are also received in oppositely grooved carriage rails 1 at the front and rear of the carriage, said rails being connected with the end bars 5 and 6 of the carriage.-

The carriage, which is power driven in the usual manner, is thus supported and mounted to travel from side to side of the machine over the top plate under control of the usual escapement mechanism (not shown), and in some instances under control of the usual tabulator mechanism.

The platen 7 is carried by the platen frame in the usual manner, said. platen frame comprising end plates 8 and 9 united by suitable cross bars. The platen frame is connected to the carriage or truck'by links 10 in the usual manner, which links ordinarilv guide the platen frame in its case shifting movements. The present machine, however, is intended to write only with capital letters or upper case characters and there is, therefore, no case shifting movements of the platen and platen frame; the platen frame being firmly held in its upper case position on the carriage, where it will coact with the outermost types 11 on the type bars 12. These type bars are mounted in a type bar segment in the usual manner to swing upwardly and rearwardly to printing position where they strike against the front face of the platen.

The usual ribbon vibrator mechanism is employed so as to interpose the ribbon in the path of the types 11 at each actuation of a type bar. Only the upper end poition of the ribbon vibrator 13 isshown, it being understood, however, that the vibrator is guided for up and down movement on the type guide 14 inthe usual manner.

As in the construction disclosed in said Hart application, there are two curved paper deflectors 15 and 16 employed beneath the platen, one arranged above the other and maintained spaced apart by intermediate spacing members or blocks 17 and 18 located channel 19 between the two deflectors, and

which is bounded at its. ends by the spacing members 17 and 18, either or both of which may constitute side edge guides or gages for cooperation with one or both side edges of a work sheet or sheets introduced into the channel 19. The other separated channel 20 is provided between the under surface of the platen and the upper deflector 15. It will be seen that the forward edge of the deflector 16 terminates in advance of the forward edge of the deflector 15. The deflector 16 is continued up at the rear to form an upwardly and rearwardly extending paper table 21, which terminates at a considerable height above the platen. On the other hand, the deflector 15 terminates in the rear of the platen at a much lower point and below the top of the platen, where it is bent to form a loop 22 that loosely surrounds a rod 23 fixedly connected at its ends to the end plates 8 and 9 of the platen frame. In this manner the rigidly united deflectors 15 and 16, together with pivotal movement on said rod. The construction is such that the heavier parts connected to the paper deflectors in the rear pivot rod 23 cause the forward edge portion of the deflector 15, normally, to belightly pressed all of the parts carried thereby are mounted on the rod 23 and have a slight.

against the platen, or against theinterposed sheets R, R. R, are held snugly against. the platen and sheets I, L, L intended to be introduced rearwardly into the channel 19 are prevented from entering the channel 20. By moving the upper end of the paper table forward, the forward end portions of the deflectors may be moved downward a limited distance, thus carrying the forward contact edge ofthe deflector 15 away from the platen.

In order to facilitate the backward introduction of work sheets into the channel 19 from in front of the platen there is provided in accordance with the Hart invention, a guide, shield or paper deflector 24 that is movable on the carriage from a substantially horizontally disposed ineffective position, shown in dotted lines in Fig. -1, to a downwardly and rearwardly inclined effective position, shown in full lines in said figure and vice versa. p

The deflector 24 has depending arms 25 at the ends thereof, each of said arms being pivoted at 26 on an end plate 8 or .9 of the platen frame. In this manner the deflector 24 is mountedfor pivotal movement from the ineffective dotted line position, shown in- Fig. 1, where it is out of' the paths of the types, to the full line position where itcrosses the printing line and extends in the path of the types. In this last mentioned position the deflector overlaps the forward edge of the deflector 16 and forms virtually a continuationof the channel 19 to aid in quickly and effectively introducing work sheets backwardly beneath the platen into the channel 19'.

It is unnecessary, for the purpose ofthe presentinvention, to disclose the means by whichthis deflector 24 is actuated and by which the fine wire line indicator 27 is automatically shifted from the effective, dottedline, to the ineffective full-line position in Fig. 1, when the deflector 24 is shifted from the dotted tothe full-line position and vice versa. It also is unnecessary to disclose herein the means by which these-devices are automatically controlled by a shifting of certain of the feed rollers 28 and 29-from the ineffective position shown in Fig. 1 into contact with the platen or a work sheet thereon as shownin Fig. '5. Nor is it necessary to disclose the means for automatically lowering the ribbon vibrator from the full to the dotted-line position in Fig. 1 when the deflector 24 is moved from ineffective to ef fective position, thus giving ample clearance between said deflector and vibrator. All of such means are fully disclosed in saidhereinbefore mentioned applications.

It will suifice for the purpose of arriving at a better understanding of this invention,

in its present embodiment, to bear in mind In this manner the sheets R,

with the work sheetR and that the parts referredto operate in the general manner indicated above.

- {is disclosed in said previously filed applications a set of feed rollers 30 coact only its carbon sheet R, whereas one or more additional sets of feed rollers 28 and 29 are employed depending on the use of the machine as a so-oalled two-sheet biller, or for more than two work sheets. The specific manner of mounting these feed rollers for shifting movement into and out of cooperation with the worksheets with which they coact has been fully explained in the applications hereinbefore referred to and need not be specifically described herein.

In accordance with the present invention certain adjustable work sheet gaging means, or paper end stops, which coact-with the bottom edge of a ledger sheet L introduced through the channel 19 are supported on the paper table and contribute to the preponderance of weight back of thepivot rod 23, spoken of above. These devices of the present invention and the manner of mounting and adjusting them will now be described.

Upright bars 31 are fixed at 32 to the back of the paper table 21 and extend upthrough openings 33. (Fig. 4) in the upper bent portion thereof. These bars are connected at their upper ends to a cross bar 34 by suitable connecting means. Such connecting'means, in the present instance, comprise headed bolts 35 and nuts 36. Each associated pair of bolts 35 also pass through openings in a downwardly extending, inclined bar 37 to firmly connect the latter to, and support it wholly at its upper end by, the associated bar 31 and cross bar 34. Each bar 37 overlies its associated bar 31, and is spaced apart therefrom to form an intervening ch'annel38. Eachchannel 38 is bounded on the rear side by the-paper table 21 and a bar 31, andon the forward side by the overlying bar 37. Each channel 38 at its lower end communicates with the channel 19 intermediate the deflectors'15 and 16. It will be seen that the lower unsupported end of each bar 31 passes down and is bent forward behind the pivot rod 23, and terminates in a bevel face 39 onits rear side where it enters the channel 19. This is to insure a sheet introduced into the channel 19 from the front of the platen, passing from the chan nel 19 up through the channels 38 between the parallel bars 31 and 37 until arrested by an end stop 40 in the path thereof. A

The end stop 40, in the present instance, is

formed as a flange extending at right angles.

&

down adjustment on the bars 37 and may be retained in any position to which it is thus adjusted by set screws 43. Each screw is received in atapped opening in the associate loop 42 and bears at its inner end against the forward face of the bar 37 received in said loop. It will be seen that the stop face or flange 40 extends in the path of the bottom edge of each ledger or other work sheet L guided rearwardly and upwardly through the channels 19 and 38 and effectively arrests said sheet.

When the lower edge portion of each ledger sheet L is to be brought to the printing line, in order to write at and near the bottom of the sheet, the range of adjustment of the bar 41 is insufficient to bring the stop 40 to a position where it will coact with the bottom edge of the sheet. Therefore, other end stops have been provided which will now be described.

It will be seen that two thin flexible or resilient metal arms 44 are pivoted at 45 on the front face of the bar 41. The pivotal mounting of these arms provides sufficient friction to hold'the arms in either of the two positions to which they may be swung around their pivots, i. e., either to the ineffective position, shown in Figs. 1, 4 and 5, where the arms overlie the bar 41, or to the effective position, shown in Figs. 2 and 3, where they extend down at substantially right angles to said bar 41. The free end of each arm is bent at right angles to the body portion thereof to form an end stop 46 against which the bottom edge of a ledger sheet L is adapted to abut when the arms are in effective position. From an inspection of Fig. 2, it will be seen that by reason of the flexible character of the arms 44 they maybe bent around the cylindrical platen and conform to the general contour of the deflectors 15 and 16, so that the stops 46 may be adjusted around the platen in the channel 19 by an adjustment of the bar 41 in its lower positions along the bars 37. In this manner the stops 46 may be brought into use to coact with the bottom edge of a work sheet L when said edge is within the channel 19 and beyond the range of the stop 40, as shown in Fig. 2.

In the present example, assume that the ledger sheets L are in the nature of printed blanks with separate spaces for various entries thereon, some at least of which are written thereon through an interposed carbon sheet L, or in some instances each bill sheet I may have a carbonized back which would answer the same purpose. Also assume that each ledger sheet has printed thereon the months of the year, or the months of more than one year. If, for example, the entries are to be made near the top of each ledger sheet in an appropriate cross line for the month of, say, January, then the operation will be as fbllows The first ledger L is introduced rearwardly, as previously described, and accurately positioned with reference to a line finder or indicator 27. When this position has been attained the end stop 40 is adjusted to coact with the bottom edge of the ledger sheet L, as shown in Fig. 1, and all successive ledger sheets adjusted to said end stop 40 will be accurately positioned to receive the January entries. When entries are to be made for the next month, February". the first sheet will be positioned with the aid of the line indicator 2? and the stop 40 is adjusted as previously described, and all successively introduced ledger sheets L may be quickly and accurately introduced to properly receive entries for that month, and so on for succeeding months.

As entries reach the lower end portion of each ledger sheet L, the lower end thereof is within the channel 19 when properly positioned to receive such entries, and each of such sheets is therefore out of the range of adjustment of the end stop 40. At this time the arms 44 may be swung down into position at right angles to the bar 41, thus bringing the end stops 46 into effective position in advance of the end stop 40. An adjustment of the bar 41 towards or away from the platen is effective at this time to adjust the end stops 46 along the channel 19 and in a curved path around the platen, as shown in Fig. 2, until the stops coact with the bottom edge of the first ledger sheet previously positioned with the aid of the line indicator 27.

In this manner entries may be made at as low a point on each ledger sheet as is required, it being understood that a single adjustment of the stops 46 suflices for entering bills during a given month and that the stops 46 operate in the same general manner, and for the same purpose as the end stop 40, but are brought into use when the stop 40 is no longer available to coact with a ledger sheet.

I have hereinbefore indicated that the present machine is capable of a very wide range of use, and may be employed with or without slight change in almost any character of billing or like work wherein two or more sheets are employed, and where one or more work sheets are introduced into and removed from the machine, while another or other sheets are retained in the machine and a certain correlation is required between the sheet or sheets retained in the machine and those introduced therein from time to time. Therefore the end stops may be employed in a variety of ways.

For example, let it be supposed that the machine is to be used as a check writing machine, in which a copy is to be made of all checks as they are written. In this event the checks only would be rearwardly introduced into the channel 19, the end stops 46 being advanced to some such position, as that indicated in Fig. 2 and permitted to remain in such position indefinitely. The record of the checks Written would be manifolded through the carbon sheet R to the record sheet R, both of which latter sheets are 'fed through the separate channel 20. In this event the sheet It would constitute a pay roll or register sheet, the use of the stops 46 in check-Writing providing for the adjustment of such stops to accord with checks of different depths.

Generally speaking, the sheet R, if used in book-keeping work with a ledger sheet, may constitute a so-called register or proof sheet. If used when copying invoices, it may constitute a sales sheet or a distributing sheet. If used in check-Writing it may constitute a payroll or register sheet. In each event, however, the sheets R and R remain in the machine while the remaining work sheets I and L (or either of them as the case may be) are removed after each writing, and new sheets entered in place thereof with the aid of the stop devices of my invention.

In some instances the stops corresponding to the stops 46 may be used without the stop 40 or the bar 41. Thus, in the modified form of construction shown in Figs. 6 and 7 an end stop is provided at the lower end of a flexible arm 48. This arm is looped at the upper end, as indicated at 49, and provided wlth'a second depending arm which terminates' in a contact projection 51. This construction is such that the flexible arm 48 is formed integral with its own carrier and may straddle over the upper edge of the paper table 52, the arm 48 extending down in front of the table and the arm 50 extending down in the rear thereof.

The contact projection 51 bears against the rear face of the paper table and with the frictional resistance of the arm 48 against the deflector 16 holds the stop device in the position to which it ma be adjusted. It will be understood that t ii's construction enables each stop 47 to be adjusted not only around the platen in the channel 19 but also longitudinally of the platen. As many of these stop. devices. may be employed, as desired, two such devices, however, being usually suflicient. v

Various changes may be made without departing from my invention as it is defined in the accompanying claim and certain fea tures thereof may be employed without range others.

What I .claim as new and desire to secure by Letters Patent, is
