Specification of Letters Patent Patented July 25, 1911.

Application filed September 21, 1908. Serial No. 453,962.

1'0 all whom it may concern:

Be it known that I, J nssn G. VINCENT, a citizen of, the United States, residing at- Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Adding and Listing Machines, of which the following is a specification.

In adding and listing machines of that type in which a plurality of rows of amount keys are employed and a corresponding number of registering wheels together constituting the accumulator, and a corresponding number of type carriers, it is customary to provide for so-called splitting of the machine, which means interrupting the coiiperation between the impression-making de vices whereby automatic printing of ciphers is accomplished. It is also old. to provide for changing the point of split at will to vary the number of decimal places on opposite sides of the split. Thus two or more columns of imprints can be run in the same series of operations of the machine, one column representing for example dates and the other amounts opposite those dates, Or the one column may represent designating numbers as of checks or vouchers, while the other represents the amounts of such checks or vouchers. Or the one column may represent measures as for instance car loads while the other represents amounts opposite such numbers. In the latter case the totals of both columns will ordinarily be desired, whereas when the first column represents dates or mere designating numbers no total need appear as a footing of such column. As these machines are usually constructed, however, the total of the date or designating numbers would be accumulated upon the wheels corresponding with the columns of keys set apart for the date or designating number prlnting. The capacity of the balance of the accumulatorffor running up a total of amounts is under such circumstances necessarily limited more or less, according to the point of split, In other words, a total exceeding the capacity of those wheels would. not be taken care of by the wheel or wheels to the left associated with the column or columns of keys used for date or designating number printing purposes because that wheel or those wheels would contain the total of the date or designating numbers.

As a total of date or des gnating numbers is useless, addition might just as well be dispensed with on the wheels corresponding to the rows of keys used for dates or designating numbers, and those wheels reservedfor extension of the total being accumulated on the balance of the wheels.

The object of the present invention is to provide improved means for accomplishing this extending of the total whereby when the machine is operated under any one of a number of possible split adjustments for the printing of dates or other numbers not to be accumulated, the total of the amounts accumulated as a result of depression of keys in the balance of the rows and operations of the machine with such keys depressed as well as keys in the row or rows devoted to dates, ma exceed the capacity of the wheels associate with the amount rows of keys, to the full, capacity of the machine when operating at normal or without a split. It follows that two columns of imprints having been run off, one representing dates and the other amounts, a total of the latter can be printed, which total may run to the left below the column of dates, thus Or, in the case of designating numbers,

thus

In machines of the above described general type it is customary to employ reciprophi eating racks and adding inions engageable therewith and disengagea le therefrom, and type carriers movable with the racks for setting upin type numbers and amounts corresponding with the degrees of moveinent imparted to the pinions by the racks. Ordinarily, when the impression devices which operate upon the type are uncoupled for producing double column work such as above referred to, the cob erative action of racks and pinions is not a "ecteds lhe present invention provides tor'subdividing the accumulator which is made up of the series of pinions and reventing pinions of one division from-being turned by racks which have advanced as a result of depression or" keys to one side oil a selected point of split; At the same time cooperation for transfer or carrying purposes is preserved between all or" the racks and all of the inions. Manipulative devices are provided whereby anyone of a number of points of split can be selected and at the same time an adjustment made which will cause a correspond;

ing number of pinions to remain unacted' upon by their racks while at the same time such pinions are available for registering any extension of the total being accumulated upon the balance of the pinions.

lhe accompanying drawings which form part of this specification illustrate t e invention as embodied in an adding and listing machine of the well known Burroughs type exemplified in William S. Burroughss Patents No. 504,963 and No. 505,078, issued September 12, 1903, but it is to be understood that the invention is not necessarily limited to employment in this particular type of adding and listing machine.

Before proceeding to describe the special devices employed for carrying out the presentinvention, some of the usual parts of a Burroughs adding machine will be pointed out. Amount keys 291 arranged in several rows on the keyboard operate as usual when depressed to set stops guided by slots in the upright plates 210 at the front of the machine and the depressionof these lreys also trips the usual latches 415 through the medium of sliding strips 214, said latches releasing the racks 610. The latter are as usual. mounted through slot-and-pin connections upon levers 011 loosely mounted independently of each other upon a central rock shaft 600 to which is fastened the restoring bail 613. The rear ends of the levers 611 carry the usual segmental series of type plates6l8 to be driven against the roller platen l? by hammers Z15. The numeral 716 designates -the usual hammer drivers '31? the latches which normally restrain said drivers and 718 usual pawls which trip said latches, the heels said pawls cotiperating as usual with inclined shoulders on the levers 611 so as to hedisabled unless the latter move past the zero position. However, the latches 7L7 trip each other from left to right for the filling in of ciphers through the medium of the usual overlapping tails d and certain coupling devices of the following description. A group of latches be ginning in the present instance with the second latch to the right and including all latches to the right up to the seventh l rom the'leit are specially constructed, the same having pivotally connected with their upper portions pitmen B, FigsQl, 2 and 9, which are widened and bifurcated at their forward ends to embrace a rod 13 and which carry pivoted catch arms or couplers B. The latter have laterally turned lips or flanges B which normally engage shoulders B on adjacent pitmen, the engagement being enforced by springs B connecting the catch arms or couplers with a suitable fixed support. It will be seen that with this arrangement the shoulder B on the pitman of one latch so equipped will operate against the lip or flange B of the pitman on the next adjacentlatch to the right to displace that latch when the first mentioned latch is displaced and this action will be carried through the group oi": specially constructed latches. The overlapping tails are omitted on all except the last latch to the left of this group and therefore the cooperative action depends entirely upon the above described couplers. It will be seen that displacement of any one of these couplers will interrupt such cooperative action.

lhe means for displacing thecouplers to effect a split comprise a shaft B mounted to turn in bearings or supporting side frames of the printing mechanism, said shaft being equipped with cam fingers B spirally arranged on the shaft (Fig. In the present instance three cam fingers are shown for displacing"respectively the catch arms or couplers of the second, fourth and fifth pitmen counting from the left, thus effecting the split ,between the second and third, fourth and fifth or fifth and sixth latches. The shaft B carries a gear wheel B in mesh with a gear segment B pivoted on the left hand side piece of the printer frame, and this segment is connected by a lever B? with a crank arm B on a rock shaft B The latter is journaled in suitable bearings in the base of the machine and'protrudes from the front thereof where it carries an operating handle B Working over a scale plate- 13. Said plate is suitably inscribed to register with the pointer on said operating arm and the latter is equipped with a.-

handle B having a spring pin 8, to engage apertures in the plate. By moving the operating arm from the zero position to one or another position where its spring pin will enter an aperture of the index plate, the shaft B will be turned to displace the corresponding coupler and effect the split.

The reference numeral 910? designates a plate somewhat similar to that ordinarily constituting the left hand side piece of a rocking frame carrying the accumulator pinions which cooperate with the racks 610.

There is also a right hand plate 910 corresponding with that usually employed and .hese two plates are mounted upon the pivot shaft 900 such as ordinarily employed and they are connected by a cross rod 910*. However, according to the present invention this rocking frame does not carry a single series of pinions extending from side to side, one for each rack, and all movable together out of and into engagement with the racks. The right hand portion of the frame does carry such a series of pinions designated 91(5 and journaled as usual. between tie plates 910 which embrace theshaft 900 and. the cross rod 9l0 This group of pinions with their numbered wheels 912 operate the same as the pinions and wheels which ordinarily extend from side to side of the-rocking frame in the regular Burroughs machine,

such pinions being normally engaged with their racks and disengaged at the outset of an accumulating operation and reengaged for the return movement of the racks, whereas in the taking of a total the pinions remain engaged with the racks during the first part of the operation of the machine and in the case of a subtotal throughout the operation of the machine. The controlling devices employed in this connection comprise the usual total key 265 surmounting a bell crank lever227 which operates a bail 224 for displacing all of the latches L15 and to which lever the slotted upper end of a link 911 is attached, the lower end of said link being connected to the usual pitman 914, branched or forked at its forward end to engage either of two studs 958 or 958 The rear end of the pitman is coupled to a triangular frame 913 carrying studs 961 and 961 adapted to be alternately acted upon by a wipe plate or pawl 821 on the upper end of a rock arm 813. The balance of the adding pinions are divided into three sections and carried by separate sub frames in the main rocking frame. The first of these sections has but a single pinion 916* jour; naled between plates 910 (Fig. 5) which are mounted to rock upon the shaft 900 and are connected by cross rods 910 The next of the sections comprises two pinions 916 journaled between plates 910 which are mounted to rock upon the shaft 900 and are connected together by cross rods 910. The third section also comprises two pinions 916, these being journaled between plates. 910 which are mounted to rock upon the shaft 900 and are connected together by cross rods 910. The cross rod 910 of the main frame extends "through the side plates of all of the sub-frames, these sub-frames being slotted as shown at e in Figs. 6 and 7 to provide for movement of the main frame independently of the sub-frames. Normally, with all of the pinions in mesh with their racks, the cross rod 910 would be occupying the forward ends of the slots 6 and consequently when the main frame rocks forwardly all of the pinions would be disengaged from the racks, the same as though the accumulator did not have the sectional construction above described. However, one, two or three of the sub-frames may remain forward when the main frame rocks back, so that all of the pinions would. not be reengaged with the racks as in the regular Burroughs machine. Normally all sections of the accumulator operate in unison. to which end the left hand sub-frame carries pivotally mounted upon a forward extension f of its left hand side piece a. latch F drawn by a spring f into eugageu'ient with the stud 958 which is made a little longer than usual. It will be obvious that the engagement of this latch over the rear side of said stud will cause the left hand subframe to be rocked rearward with the main frame. The right hand side piece of this sub-frame overlies a laterally turned lip or flange 5 of the left hand side piece of the adjoining sub-frame, Fig. 5, and the ri it hand side piece of the latter sub-frame overlies a similar lateral lip or flange 7 of the left hand side piece of thenext sub-frame It follows that when the .left hand subframe rocks rearwardly the other two subframes must move with it. At the same time both the arm either one or both of said other two subframes might return with the main frame...

without the left hand sub-frame returning.

Means are provided for so controlling the sub-frames that one or more of the same will remain forward according to the location of the split in the printing mechanism. Forward extensions a ofthe opposite side pieces of the main rocking frame carrying a cross bar a l ig. 5, against the front of which lies a slide plate '6 longitudinally slotted as at b to embrace screws a secured in the bar a. This plate projects above the bar and has a series of raised edges 6 and b of increasing length separated by depressions b and b in the plate. The left side piece of the left hand rocking subframe has a forwardly projectin arm 6 which normally engages the raised edge 6 of said plate. The left side piece of the adjoining sub-frame has aforwardly projecting arm 5. which engages the raised edge 6 of the plate and the remaining sub-frame has an arm 5* projecting forward from its left side piece and engaging the raised edge 5* of the plate. These forwardly projecting arms engage the several raised e ges at increasing distances from the left hand terminals of the raised edges as clearly shown in Fig. 5, the arms being nearest to the terminal. "It follows that the plate may he slid to the right far enough to become disengaged from said arm without becoming disengaged from either of the arms 5 or b and further that the plate can he slid to the right far enou h and the arm without becoming disengaged from the arm Z). The extreme movement of the plate to the right will disengage it from allthree arms. So

long as the plate is engaged with the three arms it is obvious thatthe sub-frames cannot remain forward while the main frame rocks rearward, but that so far as the slide plate is concerned one, two or all three of the sub-frames may remain forward when the said plate is moved to the right. Theplate is controlled by the same (lGVLCG-S which control the split. Thus the rockshaft B carries a crank arm 6 which is connected by a link 6 with the right hand end of the slide plate. It will be obvious that. when the handle 13 is moved the plate will be. moved and the-arrangement is such that the.

than the next adjacent sub-frame will also" to become disengaged from v eoeyrsr with the main frame so long as the latch F is not displaced, from which it follows that accumulations of-the different columns can be preserved whenever des1red and the totals printed, as in the examples of work shown by Figs. 12, 14: and 16.

The latch F is engaged by the hook-shaped lower end of a link F which at its u per end is connected to an arm F (Fig. 1 secured to and projecting forward from a rock shaft 200. 'llhere is also secured to this rock shaft a rearwardly extending arm F Fig. 2,, carrying a roller stud 7 which bears againsta slide strip or bar C underlying strip or bar has a cam rise f normally just forward of the roller stud f. A. pin 0 projecting from the strip up through slotsin the keyboard plate 212 and 213 is surmounted by a knob C and when that knob is pushed .rearwardly the cam rise f" takes effect upon the roller stud f with the result that the latch F is lifted out of engagement with the stud 958 through the connections above described. The said knob C works over an index plate 0 Fig. 10, which is suitably slotted td accommodate the pin 0 andv suitably inscribed to guide the operator in manipulating the knob. In the present in stance the plate is shown inscribed ExT.,

indicating extended total, and AllT., in-

dicating totals for both columns, and the knob is formed with a pointer to register with these inscriptions. A spring F connects the arm F with a fixed stud, this spring thus normally holding the arm.down and permitting the latch to maintain its engagement with the stud 958.

In order to operate for extendin the total it is of course essential that pinions which have remained out of mesh during the rearward rocking of the main frame shall return to mesh with their racks in time to take transferor carrying movements It will be understood in this connection that transferring or carrying is done as in the regular Burroughs machine, the

.pinions havingthe usual transfer projections which displace pawls 413 normally engaging over studs or pins 414: on the racks and adapted when displaced to be so held by latches 411. Extra upward movement of the racks allowed by the slot and pin connections with thelevers 611 produces the carrying movement of pinions, but this can-- not ensue until-the restorin frame 613 is raised beyond a position sufdbient to restore the racks to their. normal home positions,

, for until then the spring studs of the levers fill are at the lower ends of.the slots in e the lower keyboard plate 212. This hlide racks; It is when the restoring framq is moved far enough to return the =mcl'rsfto their normal home positions and before said frame moves farther that any pinions which remained forward are rocked rearward into mesh with their racks. This is accomplished through the medium of a link 920, Fig. 1, which is coupled to a downward extension of the left .end of the slot and thereupon thrusts the link 920 forward, rocking the said subframe and restoring its pinions to mesh with their racks, and if one or both of the other sub-frames remained forward in the accumulating o eration' they also will be rocked rearwar by reason of the'one-way connection between the sub-frames previously pointed out.

In order to prevent accidental rearward "rocking of the sub-frame, spiral springs j i the' same.

are employed connecting the arms 6 b", b

respectlvely with studs on the inner side ofthe crossbar a.

As the extended total wheels m ay be out 'of mesh at the time the transfer pawl is tripped by the adj acent'wheel of the regular set, it is necessary to provide means for pre-' venting the transfer or carrying movement of the rack for the right-hand one of the extended total wheels, until that wheel comes into-mesh with the rack. By referring to Fig. 2 it will be observed that there is swung from the same stud that supports the transfer pawl 413 another pawl 413 having a finger h separated fromits mai'n'portion a little more than the diameter of the usual stud 414 on the rack which cooperates with the regular transfer pawl. This finger it normally stands in rear of that stud as shown in Fig.2 so that it does not obstruct There is oneyof these auxiliary pawls for each section of extended total wheels and each pawl is drawn forward by a spring 71 but is normally held rearward by the associated sub-frame, the right hand side plate of which is formed with a' rearwardly and upwardly'projecting arm h having a forwardly-turned upper end portionwith a laterally projecting flange h standing in front of the-lower rounded extremity h of the auxiliary transfer pawl as clearly illustrated in Fig. 2. When the sub-frame rocks forward the auxiliary transfer pawl follows it by reason of the action of the spring 2' and the finger his then brought to position over the stud 414. The rocking back of the regular frame of course has no effect upon this auxiliary pawl. It continues to restrain the rack until the sub-frame rocks hand side piece of the outside sub-frame, Figs. 6 and 7. The rear end of back and its pinions are engaged with its racks. Then the restrained rack is released by the auxiliary pawl and the transfer may take place.

Of-course it will be understood that in order to printthe extended total all of the pinions must remain in engagement with their racks during the forward stroke of the operating handle. Now the springs j as well as the weight of the sub-frames and their pinions and wheels will tend to disengagethese pinions from their racks as the arm 813 starts rearward, relieving the link 920 of the restraint imposed upon it by the stud 9?. As before explained the extended total adjustment of the knob C keeps the latch F raised and it is preferable to avoid the necessity of changing the adjustment of the knob when the total is to be printed, as very likely the operator would be continuing a similar'character of work. Therefore an additional latch is provided which comes into play when the total key is depressed. This latch is designated by the reference let- 'ter F and it is pivoted on the same stud that supports the previously described latch F and furthermore it is of similar form and adapted to engage the stud 958 in a similar manner, being actuated by a spring f in a direction to produce such engagement. Normally this latch is upheld so as not to engage such stud, this being effected by the contact with the latch of an edge of the upper branch of the pitman 914, which edge extends in rearof the notch of said branch which normally engages the stud 958, all as illustrated in Fig. 1. It will be obvious that upon depression of the total key and consequent lowering of the pitman the said latch F will follow the pitman and become engaged with the rear. side of said stud 958, thus preventing any of the sub-frames from rocking forward independently of the main frame. T

The return of the accumulator wheels to mesh with the racks at the conclusion of a grand totaling operationis effected through the usual means employedin a Burroughs machine; the same comprising a rearwardly projecting arm 919 secured to therock shaft 900 near its right-hand end .and' having a cam edge acted upon by a roller 311 on the full stroke-sector 311, all asillustrated in Fig. 2:

The usual form of locking means is employed to prevent turning of the pinions when disengaged from their racks, said locking means comprising a frame journaled on the shaft-900 and composed of side plates 926 intermediate plates 926", with locking noses, and cross rods 926. Said frame cooperates with the usual locking-lever such as illustrated in Burroughss Patent 504,963. It will be understood that whenever the accumulator wheels to theright of the split move out of mesh with their racks the wheels to the left of the split must necessarily be moved out of mesh with their racks support capable of independent movement.

Figs. 12, 1 1 and 16 have been before referred to as illustrating work of the machine under different split adjustments with accumulation and total printing in each col umn. Figs. 13, 15 and 17 show examples of work under corresponding split adjustments but without accumulation in the left hand. column and with printing of extended totals for the right handcolumn. Whether or not the items of the left hand column are accumulated depends upon the position of the knob C In order to insure complete movement of that knob in either direction and to prevent its being accidentally moved, the slide-strip C is formed with a B -shaped portion 0 engaged by a roller-stud 0 in the upper end of a bar C slidingly mounted on the frame-work and upheld by a spring 0 What is claimed is:
