To all 'whom it may concern:

VBe it known that I, RUSSELL E. BENNER,

a citizen of the United States, residing at or where it is desired to definitely limit the length of a list for any reason, the operator will be relieved of the necessity of closely watching the printing as it progresses or counting the operations of the machine but .will be automatically notified when the maximum number of items for a single list has been printed. In machines of this character it is customary to provide mechanism which operates to automatically advance the paper step by step as themachine is operated and it is further customary in machines Wherela roller platen is employed to provide for discontinuing the automatic advance of the aper when' such platen is moved from printing position.

In Patent No. 595,864, issued December 21, 1897, on the invention of William I-I. Pike, Jr., there is shown and described a printing attachment for an adding and listmg machineof the well-known Burroughs tipe, this attachmentv comprising a laterally s ftable paper carriage supporting a roller laten in a rocking frame. When said ame is swung forward the laten is brought to printing position and into frictional' engagement with one or more driving rollers on a shaft turned step by step throughl ratchet-and-pawl mechanism, the

latter actuated bysuitable connections with set to provide for thev above referred to have been in use quite extensively for a considerable time in Burroughs adding and list-ing machines. In a more recent type the method. of automatically advancing the paper step by step has been somewhat modified by eliminating the friction drive and applying the ratchet- 'and-pawl mechanism directly to the jour-` 'nal of the rollerlplaten and instead of disfcontinuing the automatic vpaper feed by separation of the roller platen from driving rollers it is accomplished by disengaging the pawl from the ratchet -automatically by the act of throwing back the platen. In

either case `when the platen is thrown back it can be turned by hand in either direction. In the Pike construction any backward turning of the platen roller necessarily takes place when such roller is entirely disconnected from the alarm mecha nism. Consequently the stop devices of the latter which serve to reestablish the normal condition under any desired adjustment cannot be availed of to set a limit to backward turning of the platen.

One feature of the present invention is the provision of stop devices which may not only serve to restablish a normal condition of mechanism which measures the advance of the paper under different adjustments but also serve to measure backward movement of the paper as is highly desirable when several parallel vertical columns of amounts are to be printed, each containing the same number of items. Thus having arranged the paper to receive the first item of a list-and having adjusted the measuring devices so as to provide for the printing of a predetermined number of items, and such number of items having been printed, the paper can be turned backward without the operators having to watch the column of amounts or items already printed or the top edge of the paper but simply until the stop devices take effect when the paper will be positioned for starting a new column. along the same horizontal line as theA first item of the column alreadxyI printed, it being of course assumed that the paper is shifted laterall l Another feature of the present invention is the arrangement of the measuring mechanism so as to always be in step so to speak, with the paper feed whether thepaper is in printing position or not and therefore whether the paper is being advanced automatically by operations of the machine or by hand while the automatic `feed is discontinued. Thus if in running a column of figures on a sheet of limited length under an adjustment which provides for notifying the operator when the end of the sheet has been reached, the operator should for any reason after listing a number of items advance the paper by hand to line space before continuing the listing of items, the measuring mechanism would be in operation both during the listing of items and during the spacing. Consequently,the ,operator would be notified when the end .of the sheet of paper had been' reached just the same as though the listing of items had gone on continuously without any such spacmg as referred to. It will be obvious that this would not be true if, when the paper was moved back from printing position for the purpose of spacing, the measuring mechanism was disconnected as for instance in a construction such as that shown in said Pike patent.

While the present invention as to th above-specified features may be considered as broad enough to embrace constructions providing merely for the sounding of an alarm when the predetermined number of items have been listed, another feature of the invention relates to a different mode of notifying the operator when the list is complete as by causing the numbered keys `or other manipulative amount-determining or setting-up devices to become locked.

'Thus having set the indexing or measuring devices to provide for the listing of a cer` tain number of items, when that number of items has been listed the depressible amount keys will no longer yield to linger pressure and so the operator will be notified that the limit has been reached and that the paper must be run back to the starting point be ore further listing can be done. y

While, as above indicated,l the measuring mechanism can be' utilized by adjusting the paper at the starting point and adjusting an index according to the number of items to be listed, the .present invention provides for otherwise utilizing this,r .mechanism which obviates the necessit of consulting the index. Thus starting with the stop devices at normal and advancing the paper by hand until the point is reached where the list should end, the indexing device need simply be brought upagainst its own stop, the paper then run back and brought to printing position and the machine opera roughs.

Under either mode of utilizing the meas-l uring mechanism thefnotication to the operator will occur at the proper time and when the paper is moved out of printing position and run back it will be stopped at the proper point to begin a new 11st and that new list can vbe started without any readjustment of the measuring or indexing mechanism.

The invention further provides for conveniently restoring the measuring or indexing mechanism to normal when a dili'erent adjustment is desired in preparation for a different length of list. Provision is also made for conveniently disabling the measuring mechanism altogether when the machine is to be operated withoutlimit as to the length of list as for example when listing amounts on a strip of paper drawn from a roll. p

The invention is here shown and described in detail as applied to a machine of the above-mentioned Burroughs type and reference may be had for an understandingy of the principles on which machines of this type are constructed, to Patents Nos. 504,963 and 505,078, issued September 12, l893, on the inventions of William S. Bur- However, it is to be understood that the invention is not necessarily limited to the form of embodiment here shown which especially adapts it for use as an attachment to or improvement upon a machine of this Burroughs type, but the principles of the present invention may be 'applied to adding and listing or like machines of other types, the form of adaptation being modified to suit difierentconditions.

known on account of its extensive commer-l cial use and also by reason of the issuance of the before-mentioned patents and many others it will not be necessary to enter into a detailed description of the same and for the purpose of a thorough understanding of the present invention it will suiiice to refer only to s0 much of the Burroughs mecha-4 nism as intimately associated with the devices applied to the machine for the purpose of carrying out the present invention. `The delpres'sible keys 291 arranged in rows l and those of each row numbered from 1 to 9 operate to thrust rearwardly the usual sliding detent strips 214 and spring-held Ipivot-- ed detents 228 engage in apertures of said strips to hold the same in positions to which they are moved by the keys. The usual key- `releasing bail is employed, the same comprising a cross-rod 202 toact upon the detents 228 and side plates 219 securedto a rock shaft 207. The' bail is normally drawn rearward by a spring 208 and swung forwardly against the stress of such spring by the familiar wipe-pawl or cam plate 623 which takes effect at the close of the machines operation. When the bail is so rocked forward its cross-rod 202 not only lifts the detents'A 228 but lalso acts against the rea-r ends of the strips 214. Therefore if the ,bail should be .locked in its forward position no amount keys could be depressed. The present invention provides for so locking this bail. The depending arm of the right-hand side-piece 219 of. the said bail,

v'which arm carries the usual roll for coaction with the wipe-pawl 623, also carries a stud a which normally occupies the upper portion of a substantially right-angled slot b in a link B jointed to the usual error key lever Eand normally abutting the central rock-shaft 600 of the machine. This link may thus serve the usual function of a connection from the error key to the key-re leasing bail for effecting release of erroneously depressed keys. vIn the resent instance this link'serves an additional func-- tion in that by elevatingits rear end when the key-releasing bail is rocked` forward otherwise than by depression of the error key, the substantially vertical portion of the said right-angled slot'b will be caused to eIlgage 'the stud a and thus lock the bail against return movement and thereby prevent depression of the amount keys. The two branbhes of the slot are curved, one t6 accord with the arc movement of the stud a Whenthe bail is oscillated with the link in its lowered position and the other to accord with the arc movement of the link when it rises to lock the bail or lowers to release the same. This horizontally extending link B is jointed at its rear extremity to a vertically-extending link C and the latter at its lower end is jointed to an arm D secured to t-he. right-hand end of a short rock-shaft B j ournaled in bearings on the back of the machine and which has secured to its opposite end a bifurcated arm B2 embracing" a bead f on a plate F which extends longitudinally of and is secured to a rock shaft F in bearings on the laterally shiftable y paper carrlage 17. The left-hand end` of this rock shaft F (Fig. 4) has secured to it a short arm F2, andaspring F-3 connects said arm with an upper portion of'said paper carriage. This spring tends to rock the plate F downward and thus lift the arm 'D and the link B but is normally restrained from so doing by mechanism hereinafter described which measures the advance of the paper and counts the listed items. It will be seen that an operative-connection is preserved between the above-specified partsl on4 the laterally shifting carriage and the` baillocking parts in the machine proper by reason of the sliding connection between the bifurcated arm D2 and the elongated plate F.

4 ln order to provide for preventing a locking of the bail even though theabovementioned spring F3 might be permitted to act so far as the measuring or item-counting mechanism is concerned, (as when indefinitely listing items on roll paper), a plate G, (Figs. 1, 4 and 12) is slidingly mounted in the machine, being slotted to embrace a cro-ss shaftk209 and also slotted to embrace a stud b on the link B. This plate is drawn upward by a spring g and when lin its uppermost position as shown in Fig. 12 said `stud b is at the bottom of the yslot and the late therefore doesnot interfere with a ris of the Alink lB to lock the key-releasing bail. However, when thesaid plateis depressed so thatl the stud-b is in the upper end of the slot it will be obvious that said link cannot chine casing and havin on its-inner end a l act to depress the lat-ter.

substantially semi-circu ar head Gr'1L overlying the upper edge of the plate G. When the said knob is turned to a position where the inscription Oif is uppermost said headj occupies such a position as that shown in Fig. 4: where its rounded perl hery is in` cont-act with'the upper edge o said plate holding the latter depressed. The said head is rounded oli' so as to operate with an easy camming effect upon the edge of the plate and it will be obvious that in turning it'will 1n order to prevent accidental displacement of the head G* it is formed with a detaining notch vga adapted to be engaged by the nose g4 ofa catch lever gl5 pivoted to a forward extension of the plate G and connected by a spring g6 with the rear portion of the plate. It will be seen that as the head Gr4 is turned it will displace said catch lever and when the head is turned to a position where the nose of said lever may enter the notch g3 there will be yielding resistance to displacement of the said head. When the knob G is' turned to a positionv where the inscription On is uppermost the flat portion of the head G* lies in contact with the upper edge of the plate G so that the latter may occupy its upper position and present no obstruction to rise of the link B. Such a condition is represented in Fig. 12 and in' Fig. 13 the link B is illustrated as having swung upward and locked the bail in its forward position. In Figs. 1 and 4: the plate G is illustrated in its lowered position, the knob being turned to the oil' position and the link B therefore obstructed sothat the bail may swing back and forth indenitely.

Passing now to the paper-carrying portion of the machine the reference numeral 17* designates the usual roller platen which is journaled in a roking frame on the carriage 17 said frame comprisin side-pieces 17? secured to a rock shaft 17. hand end of the roller platen journal there is secured a ratchet wheel 17 d (Fig. 5) and there is loosely mounted upon said journal an arm 17 carrying a pawl 17t spring-drawn Vinto engagement with said ratchet. A link '17E is connected to said pawl-carrying arm and slotted at its lower end for engagement with a stud on an arm 17l1 secured to a rock shaft 17, said rock shaft carrying a bail 17j which has sliding'en agement with jaws of a vertical slide bar 1 on the back of the machine.

-lever is of course carried with it.

Said slide bar is engaged by a lever 17m (Fig. l) which is vibrated by a cam 17n 0scillating in ever operation of the machine. The vertical reclprocations of the slide bar 17k thus produced cause up sand down vibrations of the bail 17j and the arm 17h and this movement is transmitted to the pawl 17t to first retract the same and then cause it to turn the roller platen.

lAn abutment piece 17 (Fig. 5) may beengaged with one or another of a series of sockets in the link 17 to vary the amount of movement imparted to the roller platen, it being understood that the stud of the arm 17h moves said link upward by actin against said abutment piece and downwar by acting against the lower end of the slot v of the link.

The throwing back of the platen by rocking its supporting frame about the axis of the rock shaft 17 as a center, has the eil'ect of disen aging the pawl 17 f from the ratchet Wheel 17d. The construction employed for such purpose is of the following description: There is pivoted to the right-hand side-piece 17b of the roller platen cradle or rocking frame at the point 171 a lever having a curved upwardly-projecting arm 17 1 extending in front of a stud 17r on the pawl 17t which is drawn into engagement with the ratchet wheel 17d by a spring 17 E. The lever has a downwardly-extending arm 17t bearing against a lateral projection 17 of the carriage 17 and formed with a cam portion normally just below said lateral projection. When the platen is thrown back the said The cam portion of the lever coacting with the lateral projection on the carriage causes the lever to be rocked sufficiently to disengage the pawl from the ratchet wheel by the action of the curved upper arm 17 of said lever against the awl-stud 17 as illustrated in dotted lines 1n Fig. 5.

It will be seen that when the platen is forward or in printing position the engagement of the pawl with the ratchet will prevent backward turning of the platen but when the platen is thrown back and the pawl disengaged from the ratchet in the manner already described the platen may bel rotated backward by means of the usual knob on the end of the platen journal. The paper is as usual introduced from the rear on the underside of the platen between the same and suitable pressure rollers and the turning of-the platen in .eitherdirection carries the paper with it.

Coming now to the mechanism for meas- `uring the paper feeding and retracting movements of the platen there is secured to the left-hand end of the platen journal a small gear wheel H (Fig. 4) which normally meshes with a larger gear wheel H' soupes gear wheel H into and out of engagement with the small gear wheel H. The large r wheel is normally held in enga ement with the small gear wheel both byl e preponderanceof weight on the right-hand side arm H= in its forward position wit of the center h as the 'parts are seen in Fig. 4 and by /the action of a spiral spring It which connects the' upper part of the arm or plate H with the ower rearwardlyperojectin endof a cam lever H* of double ll cra outlinepivoted at its. upper angle to the upper extremity of said plate or arm H2 as shown at h'. In' the forward substantially vertical rtion' of this lever there is formed an angu ar' slot h* which engages a screw stud h on the platen rock frame or cradle. The sprin h tends to draw this slotted portion of t e'lever downward and en A the u per end of the slot with said stud which asv the' effect of locking the u the gears in mesh. The .lever H', however, has a linger piece H to be pressed back when the gears are to be disengaged. The first effect of rearward finger ressure 4on this lever is to rock the same on its ivot causing the upper branch of the slot to traverse the stud h, such portion of the slot being concentric with the lever. Continued pressure on the lever Awill then rock the arm Hz back both by reason of the vfact that the above-mentioned travel of the upper branch of the slot has unlocked said arm and the lfinger pressure can therefore 'take leiect tov rock the gear-carrying arm 'and also by reason of a cammin effect of the lower branch of the slot agalnst the studl h5. This lower branch o f the slot extends at an angle to the upper portion and the rocking of the lever H3 after this lower branch of the slot has reached the stud h5 necessarily causes a displacement of the arm or plate H2 as the slot continues to traverse? the stud. The engagement between the stud h? and the rear edge of the lower branchof the slot will obviously have the effect Vof camming the arm or plate H2 rearwardly When the `lever H3 is relieved of inger pressure the vspring h2 causes the forward edge'oflthe H" against the endof a ass-by pawl H* which is pivotally mounte on the plate Hz and held forward by a spring ha as illus- -trated in Fi 4.; In forward rotation the ar H w' not be stop ed by this pawl ause the stud hf may t en wipe over the pawl, the spring l1.8 yielding, but as soomas the stud has passed this sprin restores the pawl to position for stopping the reverse rotation of the gear. This gear H' is emplo ed for advancin a measuring device a lstance predetermlned according to the number of items to vbe listed in one column, and the size. of the gear is such as to provide for the lmaximum number of items which would be listed when there would be any. occasion for scttin a limit. Therefore so far as o eration o -the machine under Vany such limitation might be concerned there need be ,no such provisions as above described for permitting the gear to turn beyond a single rotation, i. e. the abutment iece for the stud il? need not be ofl the passy variety. However, as before explained, the application of the present invention to a machine of the character referred to at -the outset of this specification provides for the ordinary use of the machine for indefinitely listing items on a strip of paper drawn from a roll and this would call for indefiniteV turning of the said gear wheel H. which it will have been seen 1s rovided for by the above-described passy pawl construction.

When the machine is being operated under an adjustment for-limiting the number of itemsincluded in a single column it is highly desirable that the backward turning of the platen shall bring the paper to the same starting point each time and it will bel obvious that the stop devices above described will serve this purpose inasmuch as the gear H will always be stopped at the same point by the abutment ofthe stud h" against the pass-by pawl H4, and inasmuch as said gear turns with the platen. These stop devices also come into play when the gear wheel H is disengaged from the gear wheel H after limited columns of items have been printed and it is desired to change the adjustment. The gear wheel H (Fig. 7) carries on its inner side a spring barrel Hi and a volute spring H's within said barrel has frictional engagement at its outer end with the same and at its inner end is secured to the sleeve h through the medium of a collar h secured to said sleeve 'vancing movement of the platen being in.

opposition to the spring so as to wind up vthe latter. y Of course the .action of the 20 on the arm F2. When the finger is upon the spring in returning theI gear is limited by the abutment of the stud z.T against the passby pawl H. 4

Referring now to the indexing devices by which the number of items to be listed may be determined a shaft I extends through the sleeve it which supplies a bearing for the shaft and on the inner end of the latter there is secured a disk I which is formed in its periphery with a notch (dotted lines Fig. 4 and full lines Figs. l0 and 1 1), said notch being of substantially segmental outline abrupt at one end and beveled or sloped at the other end. A finger I2 pivoted at on the carriage 17 is formed at its upper end with a lateral angular lip 2 overlying the periphery of the notched disk. This finger has. an extension 3 forward of its pivot, which extension has-jointed to it a link 4 slotted at its lower end to embrace a stud f unbroken periphery of the disk said link is lowered, bringing the upper end of its slot upon the stud f. Upward movement of the arm F2 by the spring F 2, which it will be remembered has the effectl of locking the keyreleasing bail and preventing depression of the keys, cannot take place so long as rearward movement of the finger I2 is obstructed by the notched disk but when the notch of the disk comes opposite the lateral lip 2 of said. finger obstruction to rearward moved ment of the latter is no longer presented by the disk and so the spring F3 is not thereby prevented from acting.

There is secured to the shaft I outwardly beyond the gearH (Figs. 7 and 9) a radial arm J bifurcated at its outer end and there is slidingly mounted upon the shaft outwardly beyond this arm a disk J having a stud y' occupying the bifurcation of -said radial arm so that the disk J and the shaft I will always be rotatively engaged though said disk may be moved longitudinally of the shaft. The disk is formed with a knurled knob J 2 by which to manipulate it, the said knobbeing in the nature of a hub surrounding the shaft. It is recessed to accommodate la spiral spring j which is confined by a screw f2 entering the shaft I (Fig. 7). Said spring serves to thrust the disk inwardly against the outer side of the gear H. 'Ihe disk has a peripheral fiange J 3 to bear against said gear and this fiange is graduated and suitably inscribed to correspond with the vfeed movements of the platen. The gear H has a radial mark j* (FigA) with which any one of the gradual@ tions on the flange J 3 may be made to register, thus determining how far the paper may be advanced before the`amount keys will be locked. Of course when thefindexin disk -has been adjusted to register the esired `graduation mark with the mark on the gear wheel it should be so engaged with the gearl Apin jT by a spring js (Fig. 4).

wheel as to rotate as a part thereof. To thisV end there is secured to thedisk J (Figjf) a dog js which preferably is in the forln'of an 'angular piece secured to the inner side of the disk andL projecting through a notch' 7'0 in the flange and formed at its outer extremity with a number of laterally projecting t teeth to engage the teeth of the gear wheel, being withdrawn laterally therefrom when the disk is moved outwardly on the shaft and of course thrust laterally into the teeth of the gear when the disk is released and the spring 7" moves the disk against the side of the gear.' Turning of the disk back. wardly when withdrawn from engagement 804 with the gear wheel is limited by the'abutment of said dog against a pass-by pawl J 5 mounted on a stud j carried byl a forward projection of the rocking plate 4or arm H2. When the disk is interlocked with the gear wheel saidpass-by pawl does notstand in t-he path of the dog but when the disk is withdrawn from engagement with the gear the dog will encounter the pass-.by pawl when the disk is turned backward. This pawl will yield under forward turning of i the disk, being h'eld against a suitable stop It shouldV be noted'that the gear wheel H is wider than the platen gear wheel andV that the 95. teeth of the dog can only project half-way across the teeth of the gear wheel H' (Fig. 7). Consequently, the intermeshing of the gear wheels is not affected by the engage, ment of the dog with the teeth of the larger 10o wheel. j j

As the notched disk I is secured to the same shaft with which the flanged disk J is always rotatively engaged it follows that the relation between the notch of the disk I and the line-spacing. scale made up of graduations on the flange J 2 of the disk J never varies. Consequently, the setting of the fianged disk at different positions will vary the point at which the notch of the i disk I will arrive opposite the lip of the l finger I2. The normal position of the measuring gear H, being the position to which it is brought by .its spring Hf as before explained, is such that the indexing mark j? is at the upper side of the wheel where it can be conveniently-viewed when adjusting the indexing disk.' It will be obvious that the adjustment of the latter with relation to said mark will determine the point at which the notch of the disk I will permit thelocking of the amount keys to take place. Thus if the column of items is to be limited to ten the indexing disk will be disengaged from the gear wheel and 125 turned until the graduation mark opposite the inscription 10 registers with the mark y'4L (as shown in Fig'. 10) and said disk then rengagedwith the, gear. The latter being A at normal when the work begins the amount keys will be locked after the printing of the tenth item (as indicated in Fig. 11 assuming of course that the automatic inespacin mechanism is adjusted to correspond with the aduations on the index disk. These gra uations will referably be made to correspond with sing e spacing, e., advance of the platen a distance of a single tooth of the ratchet wheel. It will be noted that in Fig. 5 the tap et-piece 17 is posi- ,ing and sto mechanisms of t e resent in'- -vention nee not necessarily be ollowed in 'order to secure the desired column regulation.

tioned to rovide for t is single spacing.

It will seen that with the above construction applied to a machine of the charg acter indicated it will only be necessary when the length of columns is to be limited on account f limited length of paper, for exam le, to start with the measuring ar wheelpat normal and set the indexin isk according to the number of items to e included in one column, then proceeding with the listing in the ordinary way. The lockg ing of the amount keys upon the printing 'as far as it will o.

of the last item notifies t e operator that the limit has been reached. Assumin that columns of items are to be printed slde by side as will ordinarily be the case when there is occasion to use devices such as those provided by the present invention, the operator ,-will then shift the carriage to the left,'throw back the platen and then rotate it V.backward The stop devicesbefore described limit such backward rotation to the point where the first column of items started. If the work being done includes continuous addition of items or amounts then it` will usually be desirable to print a sub-total at the bottom of the first column which can be done after the amount keys have become locked. The locking of such keys does not aifect .the sub-total or total keys or prevent movement of the operating l handle and parts connected therewith. Consequently, when the amount keys become locked, indicating completion-of the column, the usual spacing stroke can thereupon` be taken and then the sub-total or total key depressed and the handle again operated to print a total or sub-total. Wherefa total is to be carried to the next column it is preferable, when the platen has been turned backward as above described, to first again print the sub-total before proceeding with'the listing. This sub-total will appear on the same horizontal line asl the irst item of the column already printed, or it may be opposite the imprint of a specialcharacteredenoting a clear condition of the machine before the starting of the work. Then following items.

will appear opposite items of the first column respectively down to the last added one" thereof when the keys again become locked.

Of course the total ,pressing back the lever described can be continued for as many columns as desired and all sub-totals at the to of columns will be in the same horizonta line and all sub-totals at the foot of columns will also bel in the same horizontal of the last column will or inarily be a grand ,total and not a sub-total but it would be in Having caused the measuring ear =to assume normal position, which as be ore explained can be done at anIyI time by simply and having thrown back the platen, the latter may be advanced by hand until the paper is advanced to the point where the columns `should end. Then the indexing disk may be drawn out disengaging it from the gear and turned backward as far as it will go, t'. eyuntil the dog y" comes up against they .pass-by pawl'J (Fig. 4)'. lThis brings the notch 'i of the disk I opposite the lip 2 of the finger I2 as shown'in `dotted lines in Fig. 4. The gear.y H has, however, been turned by the turnin forward of the platen so that the stop stu h" is not at normal as rinted at the foot in Fi 4 but advanced a distance corresponding with the advance of the platen. The latter will now be turned backward as far as it will go, i. e. until the said stop stud It comes up against the pass-by pawl H4. This of course means that the platenl is turned backward exactlyv the same distance it had previously been turned forward. The indexing disk being at this time interlocked with the measuring gear, (this having taken place upon the release of the disk after its eing turned back as above described) the backward turning of the gears carries the notch z' away from the lip z2 of the linger I2 a distance corresponding With the extent to which the platen has been turned backward. Consequently, when the listing thereupon ensuesvthe notch will again be brought opposite the lip of the finger when the platen has advanced tothe same extent'it Was pre- 115 viously turned by hand and the locking of the amount keys willtherefore take place at the point previously determined upon when the platen was turned forward by hand.V Further columnar printing will be carried on the lsame as already described in connection with the other method of using the measuring mechanism.

While as before stated backward turning of the index disk is limited by the abutment of the dog against the pass-by pawl J 5, the latter' will lyield to the turning ofthe disk in the opposite direction and so ifior example the index disk is to be shifted rom'an adjustment for twenty items to an adjustworked and of course when the handle isv pulled with the platen in printing position the line-spacing will take effect whether amount keys are depressed or not. notch in the disk I is sufliciently long to -alloW for several strokes of the operating handle after the amount keys have been locked, thus providing for the spacing and total-printing above referred to, without affecting the locking connections. Of course it is to be assumedthat the operator, having run a column of items and printed a total at the foot of the same, will have no occasion to further operate the handle of the machine until the paper has been run back for the starting of a new column. But if the handle is pulled more times than the length of the notch in the disk I provides for no disastrous results will ensue for as before eX- plained one edge ,or side of said notch is beveled andthe lip of the finger I2 is angular so that such excessive operation of the handle would simply result in the linger being cammed out of the notch and the keyreleasing bail unlocked. This might be availed of where for some reason a certain groups of items'. i-n the same column. Thus themeasuring mechanism might be set for the printing of a predetermined number of items and then instead of turning the platen 40 backward and shifting the paper carriage when the amount keys became locked, the operating handle could be pulled until `the amount keys became unlocked and the listying could then be resumed. However, ordinarily when itemsare to be listed in a col- `umn .of unlimited length the amount key .locking mechanism would be disabled altogether by theuse of the knob G.

It will be noted that when the platen is thrown back the finger I2 will be rocked rearwardf by the platen journal and the link I4 thus elevated so that it no longer obstructs the arm. F2. Hence with theplaten 4thrown back the amount keys will become locked as a result of a single stroke of the operating handle. But upon bringing the platen forward again the keys would be unlocked by reason of the action of the link 4 upon the stud f, unless of course the notch of the disk 3. I wasopposite the lip of the finger I2 in which case the amount keys should of course remain locked. This locking of the amount keys as a result of throwing back the platen is infact a desirable feature inasmuch as it 'p65 prevents repeated operation of the machine The v amount of spacing was desired between 'in -such manner as to project the type rear- .per feeding devices, an'fl means controlled by the latter for automatically locking the setting-up devices after a predetermined number of successive operations of the feeding devices with provisions for disabling said means at will.
