ADDING-MACHINE,

Specification of Letters Patent.

Patented July 3, 1906.

Application filed December 2, 1905. Serial No. 290,009.

To all whom. it may concern.-

Be it known that I, CLAIBORNE W. GoooH, a citizen of the United States, residing at Lynchburg, in the county of Campbell and State of Virginia, have invented certain new and useful Improvements in Adding-Machines, of which the following is a specification.

My invention relates to adding-machines of that class adapted to print and list individual items and to accumulate and print the totals thereof and also to print such total at the will of the operator, such class of ma-- chines being exemplified by the Well-known Burroughs adding-machine constructed and operating in substantial accordance with Burroug spatents, Nos. 504,963 and 505,078, issued on September 12, 1893.

The object of my invention is to provide novel and efficient mechanism for splitting the machine into a plurality of separate sections, whereby the sections may be employed for printing and accumulating items of different character.

Another object of my invention is to make provision for changin in convenient manner the'line or point of sp it and for locating it at any line or point between any two denominations of the regular machine and also to make provision for splitting the machine at a plurality of lines, whereby the machine may be split in three or more sections, as may be de sired.

y invention has for its further object the elimination of one or more sections so far as the printing of the total accumulated thereon is concerned, whereby the total of those items only which are required to be accumulated and their total to be printed is recorded.

My invention embodies other novel and advantageous features of construction and operation, which will be apparent from the description hereinafter iven.

In the drawings, igure 1 is a left-hand side elevation of a Burroughs machine, but illustrating only those parts of such machine which are more or less concerned with my improvements; Fig. 2, a sectional elevation of the printing mechanism of the machine;

Although I have illustrated and will hereinafter describe m invention as embodied in a Burroughs mac e, yet it will be understood that my invention is not to be limited in its a plication to this particular make or style 0 machine, inasmuch as may find useful ap lication in adding-machines of other mal es and other constructions. Moreover, inasmuch as my invention has more particular relation to the printing and totalizing mechanisms, the other mechanisms of the complete addin -machine have been omitted; but for an unferstanding and detail description thereof reference may be had to the aforesaid Burroughs patents.

As is well known, a Burroughs adding-ma chine is provided with a series of keys 291, mounted in a keyboard and arranged in rows or banks representing different denominations, increasing from right to left, and of a number accordin to the desired capacity of the machine, the l feys in each row being numberedfrom 1 to 9 to represent the different digits for each denomination. These keys v are arranged to control the extent of movement or oscillation of a series of main levers or sectors 611, mounted or hung upon a main transverse shaft 600, each row of keys being provided with a corresponding sector 611. Each of these sectors is provided at its rearward end with a series of five separate and movable type-plates 618, each plate bearing two separate type and all of the type of eac sector representing the nine digits and the cipher. The other or forward end of each sector 611 is provided with a rack 610, whose degree of descent is determined by the value my invention IOC corresponding row of keys. Each rack 610 meshes with is corresponding pinion 916,

forming a part of the accumulatmg mechanism and provided with the usual adding wheel or dial 912. The descent of the rack 610 through the distance permitted by the particular key depressed raises the rearward or type-bearing end of the sector 611, so as to present the particular type corresponding in value to the key depressed to the printing line of the platen or paper-support 1599, with the result that when the hammer 715, forming a part of the printing mechanism, is operated such particular ty e will be impressed upon the paper on the p aten.

The series of accumulating-pinions 916 are mounted in a rocking frame composed of side plates 910 and arranged to rock or swing upon an axis or shaft-900. This rocking frame is operated by moving parts of the machine in such manner that upon the initial movement of the main operating-shaft of the machine the pinions are all rocked out of mesh with their racks 610, so as to permit the racks corresponding to the rows of keys in which the keys have been set or depressed to descend distances corresponding to the value of such depressed keys. Upon the further operation of the machine and immediately before the ascent of the racks the accumulating-pinions are swung back into mesh with their racks, with the result that such pinions will be turned by those racks which have been operated, as stated, so that the item set up on the keyboard will be transferred to the accumulating-pinions. In the present instance these means for so controlling the operation or rocking movement of thepinions comprise a main rocking lever 813, mounted on the main rockshaft 800 and carrying at its upper end a wipe-plate 821, which is adapted to cooperate With-the three-arm lever 913, with the result that such lever is oscillated first in one direction and then in the other in each complete operation of the machine. The lower or depending arm of the lever 913 is pivotally.

connected to a pitman 914, whose forward end is arranged to cooperate with the rocking frame 910 of the pinions in the usual and Wellknown manner to accomplish the results just stated. To control the operation of the pitman 914 and consequently the operation of the rocking frame 910 for the pur ose of permittin avtotal or a subtotal to be taken at the wil of the operator, there is a total-key during the forward movement of the operating-handle of the machine, and the release of that key during the return movement of such causes a subtotal to be printed. The depression of the total-key interferes with the usual operation of the pitman 914 by preventing the forward rocking of the pinion-frame, with the result that the pinions are leftin mesh with their racks during the descent of the latter, and such racks descend distances as permitted by the pinions which are returned to zero so that the amount thereupon presented by the type to the platen corresponds to the accumulation on the pinions 916. If the total-key is heldde'pressed during a complete operation of the machine, the pinion-frame is caused to be swung forwardly out of mesh with the racks and kept in such non-engaging position in the ascent or restoration of such racks, so that the pinions which have been reset to zero position in such totaling operation are left in that position. In other words, a grand total has been taken, and the machine has been cleared. If now after the total has been printed, as just stated, the total-key is released and permit ted to ascend to normal position, the pinionframe will not be swung out of mesh-with the racks, but left in mesh, so that the values which have been transferred from the pinions to the racks will' now be transferred back again. In other words, the particular total which has been taken isa subtotal, for the accumulation has been retained in the machine. As herein shown, in Figs. 1 and 7 the bellcrank 227 is connected, as usual, with the.

horizontal link 226, which'is in turn connected with the depending arm 227%, certain parts of my attachment, as hereinafter described, being arranged to cooperate Withthe left-hand-side plate 710 both of which I are mounted upon the shaft 600. These hammers are actuated by drivers 716, IIlOIlIllJOd'OIl a cross-shaft 702 in the printing-frame and provided with studs 753, 10-

cated near their upper ends and arranged to be received within the curved slot 715 of its hammer. Each driver and its hammer is normall held retracted,'bu't upon the release of t e driver the hammer is driven rearwardly by the action of the stud 753 in the slot of the hammer. Each driver 716 is under the control of its latch 717, whose lower edge is provided with a shoulder or hook to engage the u per end of its driver. it being understood t at there are as many of these latches as there are hammers and latch, inasmuch as in drivers. These latches 717 are mounted upon a cross-shaft 700 in the printing-frame and are in turn controlled by a series of pawls 718, corresponding in number to the number of hammers, drivers, and latches mounted on a cross-shaft 704, supported at its ends in a frame arranged to oscillate in the operation of the machine and provided with rearward hook-shapedends ada ted to rest upon the upper edge of their late es and to engage shoulders thereon in case their corresponding levers 611 have been operated, but prevented from such actuation of their latches 717 by reason of the contact of the tails of such pawls against the inclined shoulders 611 of the sectors 611 when in their normal or non-operative position, with the result that at such times the pawls 718 will be swung upwardly as to their rearward ends, so as to clear the shoulders on the upper edges of their latches. In order to provide for the transfer of the hammer action from left to right for the the latches 717 are provided with tails d, which are extended laterally, so as to overlie the forward ends of the next succeeding latches on the right, as clearly indicated in Fig. 3. The construction of printing mechanism as just described is that which is common in the ordinary Burrou hs machine; but in the present instance, w lu'ch contemplates the splitting of the machine and particularly of the printing mechanism, 1 rovide two special forms of latches 717, w 'ch are illustrated in perspective in Fig. 6. Before describing the construction and mode of operation and purposes of these special latches I will state that the same may be disposed or assembled at any particular point or line in the series of regular latches 717 and also that any desired number of sets of these special latches may be provided and assembled at any desired number of points among the series of regular latches, according to the number of sections into which it is desired to split the machine. Referring to these special latches, one of them (marked 717) is the same as a regular latch 717, with the exception of the omission of the tail d and the provision of a recess 7-17 on its upper edge, such recess having its rearward side straight or vertical and its front side sloping, as clearl indicated in- Fig. 6. The other special latc 717 is similar to a re latch 717, with the single exception. 0 the provision of a recess 717 on its upper ed e, whose respective sloping and straight si es are the reverse of those of the other special the special'latch 717 it is the front side of the recess which is, formedabrupt or straight. This second special latch is, however, provided with-the usual tail 01, like the regular form of latch. Inasmuch as the transferring-tail d of the printing of ciphers speciallatch 717 is omitted the machine is split at a line or point between the special latches, and so far as the machine has been described the hammer action cannot be transferred from the left to the right of such line of split. However, provision is made for bridging this line of split when it is desired to operate the machine in its entirety as a regular machine operating with the full capacity of keyboard, and in the present instance such bridging is accomplished through the medium of what I will term a coupler, marked A and clearly illustrated in Fig. 6, where such' coupler is shown grouped with the two special latches, but not in cooperative relationship therewith. The construction and arrangement are such that when this coupler is in operative relationship with the latches the line of split is bridged and the latches transfer the hammer action for cipher-printing in the same manner as if the special latch 717 were provided with the transferring-tail d. The coupler consists of a curved arm, whose forward end is provided with an open-ended coupler may be slipped over the transverse rod or shaft 706, secured at its ends in the side plates 710 and 71O The rearward end of the coupler is provided with two laterally-extending pins a and a which may, however, be a sin le pin extending through the coupler and projecting from either side thereof, although for convenience in description the same will be hereinafter referred to as two separate pins. The pin a is arranged to be received within the recess 717 of the special latch 717*, when such coupler is in position to bridge the line of split and to couple the two special latches.

he other pin a is arranged to. be received within the recess 717 when such coupler is in its 0 erative position. It will be obvious that wffen the coupler is in its operative position, with its two .pins within the recesses of the special latches, as indicated in Fig. 2, the oscillation of the special latch 717, caused either by reason of actuation from its own pawl 717 or from actuation by the tail d of the next adjacent but regular latch on the .left, will move the coupler forwardly in unison with the special latch 717, it being understood that the abrupt side or wall of the recess 717 will at this time press against the pin a. This movement of the special latch 717 and of the coupler is transmitted to the other special latch 717 by reason of the pressure of the pin a against the abrupt side or wall of the recess. 717. Thus the special latch 717' is oscillated in substantial unison with its companion special latch, to thereby release its own hammer-driver and also cause the tripping of all of the latches to the right for cipher-printing. When, however, the coupler A is moved or oscillated upslot a, whereby such wardly to thereby remove its pins a from the recesses of the special latches by mechanism hereinafter described, the machine op crates as a split machine, with the line of split between the two special latches.

While in the present instance the line of split is between the sixth and seventh denomiditional sets of these special latches and couplers are employed. In order to enable the line of split to be changed conveniently and at will and also to enable a plurality of sets of special latches to be employed in the machine, I so construct the cross-shaft 7 06, on which the coupler is pivotally mounted, that such coupler may be adjusted to a plurality of positions corresponding to the spaces between the latches and also in such manner that such shaft may receive additional couplers along its length and properly position and retain them. As indicated in Figs. 2 and 3, this shaft 706 is provided with a series of deep circumferential grooves 7 06', which correspond in position to the spaces between the latches and which are adapted to receive the forward end of the coupler or of a plurality of couplers. As shown clearly in Fi s. 2, 3, and 4, the construction of the coup er. is such that it may be readily removed from its supporting-shaft 706 and placed in any other groove'70'6 of such shaft, and at the same time the set of special latches is correspondingly adjusted along the shaft 700 by substitution for two regular latches.

The mechanism, which is under the control of the operator, for operatin the coupler A, and thereby determining w iether the machine is' split "or normal,'comprises abail B, whose parallel arms are connected to a crossrod 1), journaled in the side plates .of the frame of the-printing mechanism, although, as Wlll be evident, an operatingconnectionextending onlyt'o the movable'arm'bo'r coupler A'would be 'required in case the coupler had a relatively fixed position transversely of the printing mechanism. When thebail is moved downwardly in the manner hereinaf5 'ter explained, the forward end of the coupler is likewise downwardly moved and the rear-" ward end of the coupler correspondingly elevated to remove the same from cooperating relationship with the special latches. This bail extends entirely across the width of the printing mechanism in order that-it may be enabled to. contact and operate a coupier to whatever position the latter may be adjusted or to contact and operate all of a series of such couplers disposed along the length of the supporting-rod or rock-shaft 706, as will fbe obvious from an inspection ofFig. 3. This bail is in the present instance key-controlled by reason of the provision of a special key C and operating connections between the bail and such key. In the present instance the shaft 1) is extended through the side plate 710 of the frame of the printing mechanism and provided with a depending crank-arm I), having at its lower end astud b. This stud isoperatively connected with a reciprocating link or operating-arm D, having its forward end upwardly curved or extended and there operatively connected with a crank-arm e on a second rock-shaft E,-suitably journaled at its ends within the machine. This rockshaft is provided at a point toward its lefthand endthat is, toward the left-hand side of the machine-with a second crank-arm .2, having a long stud E extending laterally toward the left, Fig. 10. This stud e is arof the special key C, with the result that when such special key is depressed the rockshaftE is rocked in an anti-clockwise direction when viewed as in Fig. 1, and the machine is changed from a complete to a split machine by operation of the connections, as hereinafter more particularly explained.

.. As clearly indicated in Fig. 1, the stem of the special key is irregular shaped, having two bends providing two substantially vertical portions and a connecting horizontal portion, with the extreme lower end longitudinally slotted in order to fit over and be guided by the cross-shaft 600 of the machine, Figs. 1, 7, and 9. The rearward edge of the extreme lower end of this key-stem is extended, so as to provide a contact-surface c to bear against the long stud e When the special key C is depressed, theentire key-stem 1s bodily depressed, and when the key isfully depressed the shaft 600 is positioned at the upper. end of the slot in suclikey-stem. The special'key is arranged to beheld in tWo different. depressed positiOns-towit, a position of run depression and an intermediate positionftowhichend'the uppenpbrtion of the key-stem is provided with two shoulders 0 0 arranged to look under the'hower plate 212 of the'keyboard. However, so far as the mechanism for splitting the machine is concerned only one of these pdsitions of the key stem is necessary, inasmuch as the depression of the key beyond said intermediate positiori has no effect upon the bail B, the full movement thereof .being accomplished in the first portion of the depression of the special key.

As hereinbefore stated, the stud b of the bail is operatively connected with the operatchine having a plurality of ing arm or link D but in the present instance this connection consists of a coiled spring 6 fastened at one end to the crank-arm b and at the other end to the link D intermediate the length of the latter, as clearly indicated in Figs. 1, 3, and 7. provided with an openended slot to receive the stud b the inner end of the slot being held against such stud by the-tension of the spring b which holds both the link D and the rock-shaft E -in the normal position, which is indicated in Fig. 1. When, however, the shaft E is rocked positively by the depression. of the special key C, as hereinbefore described, the link D is moved or reciprocated rearwardly, thereby tending to withdraw the end of the slot thereof from the stud 62 but by reason of the provision of the sprin 6 such stud follows up the link D, and there y permits the bail B to rock downwardly, with the result that the coupler A is moved up to an inoperative position with its pins a and (1 out of cooperative relationship with the special latches, under which conditions the machine is a split one. As hereinbefore suggested, it is immaterial so far as the splitting mechanism is concerned Whether the key is depressed to the first or second notch or shoulder, inasmuch as the depression to the first shoulder is sufficient and without further effect upon the bail B, because the contact-surface 0 simply continues to slide on the long stud a without further effect on the latter. Upon the release of the special key the latter is restored to normal or elevated position by the tension of its spring 0, and the rock-shaft E andthe link D and also the bail B are restored by means of the action of the sprin 6 In addition to t e above-described mechanism for splitting the machine I provide mechanism cooperating therewith for eliminating the printing action of any one or more of the sections into which the machine is split. In the present instance I have shown such additional mechanism as arranged to cooperate with the left-hand section of a split machine, although, as will be understood and will be hereinafter made apparent, such additional mechanism may be arranged to cooperate with the right-hand section or with any one or more sections of a split malines of split. Moreover, the construction and arrangement is such that the additional mechanism is caused to operate to eliminate the printing action of its section in an automatic manner and by the act of taking a total with the machine, such mechanism being in the present instance under. the control of the totalizing mechanism. 4

Referring to the present construction, the mechanism for so eliminating the printing action of a section of a split machine comprises a bail F with its parallel arms connect- Moreover, the link D is' ed with a rock-shaft f, journaled at its ends in the side plates of the frame of the printing mechanism. The lefthand end of this rockshaft f extends through the side plate 710 and is there provided with a bent crank-arm f, having at its extreme end a pin or stud f which is received by an open-ended slot in the rearward end of the link or operatingarm D. This bail F is held in its raised or inoperative position away from the hammers 715, as clearly indicated in Fig. 2, with a yielding pressure, in the present instance by means of a spring 7, fastened at one end to the crank-arm f and at the other end to a pinf, extending from the side late 710, as seen in Fig. 3. When the bai F is in the normal or elevated position (indicated in Figs. 1 and 2,) all of the series of hammers are free to operate in the usual and well-known mannerhereinbefore described; but when such bail is rocked downwardly to the position indicated in Fig. 7 by 0 crating connections hereinafter described tl e bail is swung into the vertical lane of movement of all of the hammers and serves to arrest all of the hammers of the left-hand section of the machine; but none of the hammers of the ri ht-hand section of the machine are interfere with by the bail, owing to the fact that the hammers of this latter section are cut away at 715 as is clearly indicated in Fig. 4, whereas the hammers of the left-hand section of the machine remain of the usual construction, as indicated in Fi 5. It results from this construction an arrangement that while the hammers of the right-hand section of the machine are permitted to operate in the usual manner to strike their type-plates and cause the impression the hammers of the lefthand section are prevented from operating, inasmuch as after a partial rearward movement the same are arrested and revented from delivering their blows upon t eir type-plates, so that under these conditions the printing mechanism of the left-hand section of the machine is inoperative and no impression will be made notwithstanding the existence of an accumulation on the accumulating-pinions corresponding to this particular section of the machine and notwithstanding also the elevation of the corresponding type-plates to printing position.

It will be understood that the printingcontrolling bail F is not directly under the control of the special key C and is not operated by the depression of such key, but is under the control of the totalizing mechanism, which causes the swinging of the bail F after the special key 0 has been depressed or set to its lowermost position. It therefore results that separate and independent items may be printed on both sections of the machine and separate accumulations kept thereof, but that the accumulation or total of only one of these lists of items is printed and recorded, it being understood that those items which are not footed or totalized represent such items as are not required or desired to be accumulated.

In order to accomplish the results just stated, I provide means arranged to be operated in the act of taking a total for rocking the shaft E farther than it is rocked by the special key C, with the result that the bail F, which has heretofore remained idle and in its normal or elevated position, will be swung downwardly, with the result hereinbefore mentioned, while the other bail, which controls the coupler, is uninterfered with and not moved farther. According to the present construction the means which I have provided to accomplish these results consists of a-link or lever G, shown by itself in Fig. 8 and pivoted at its forward end to the connecting-link 226 of the totalizing mechanism. Under normal conditions when the totalizing mechanism is operated the link G is inoperative and reciprocated freely in unison with the link 226; but such link Gris under the con trol of the special key C, which is arranged to render such link operative upon the full depression of such special key. To this end a pin-and-slot connection is provided between the special-key stem and the link G, in the present instance the link being provided with a slot G and the key-stem with a pin 0 whereby when the special key is in normal or elevated position the totalizing mechan ism is permitted to operate in the usual and well-known manner. However, when the special key 0 is depressed to its full extentthat is, to the extent of the second tooth or shoulder c the rearward end 9 of the link G, which is downwardly curved, is projected into the path of the long stud 6 with the result that when the totalizing mechanism is operated and the link 226 thereby shifted rearwardly the link G is correspondingly reciprocated, whereupon the stud e and con sequently its rock-shaft E, is rocked to a greater extent than by the special key- C. This extra movement has no effect upon the bail B, which hasbeen moved to its operative position upon the first depression of the special key; but such extra movement causes the operation of the printing-controlling bail F, so that simultaneously with the depression of the total-key the bail F is placed in position to eliminate the printingaction of the left-hand section of the machine. The idle condition of the bail F during the operation of the special key and'its active condition u on the depression of the total-key after t e special key has been set are brought about by the provision of the slots in. the link D, the stud normally occupying a position intermediate the length of its slot, so that the movement of the link D, due to the depression of the special key, can have no effect upon case of the stud b the end of the slot which receives such latter stud simply moves away therefrom when the link D is operated by the totalizing mechanism. The relative -positions of the different parts'concerned with my improvements when the totalizing mechanism is operated with the special key depressed is illustrated in Fig. 7, wherein the rockshaft E is shownas rocked rearwardly to its full extent by the link G,thereby shifting the connection or link D rearwardly to its full extent to thereby throwdown the bail such stud and its bail F, whereas in the F' to its operative position to intercept and arrest all of those hammers which are of regular constructionthat is, .unprovided with any cut-away portion, such as illustrated in Fig. 4.

' It will be understood that the right-hand section of the present machine may be the one provided with special hammers, such as shown in Fig. 4, and ,that the left-hand section of the machine may be provided with the regular hammers, such as shown in Fig. 5. Furthermore, it will be understood that in case the machine is split at a plurality of points or lines any one or more of the sections may be provided with such special hammers to prevent printing action in the operation-of taking a total, such result being accomplished by the proper disposition of the special hammers among the series of hammers. It is owing to this possibility and desirability of adjustment in the machinethat the interference with the hammer action is made in the form of a bail, so as tointercept any series of special hammers wherever they may be arranged transversely of the printing mechanism, although such interference need not extend all the way across the printing mechanism in case the hammers of one side only of the printing mechanism are always to be the ones to be interfered with. Finally it will be understood that the relative number of special and regular hammers will vary according to the capacity of the different sections of the machinethat is, the same will vary according to the change in the location of the line of splitting in the manner hereinbefore explained.

In the present instance the machine is normallya com lete machine with the full capacity of the eyboard available to the operator, but is adapted to be split bymanipulation of the'special key and arranged to be restored instantly to complete condition by simply releasing the special key. Thus the range of practical use or application of the adding-machine is considerably increased, inasmuch as it is not only adapted to the usual operations of printing, listing, and totalizing, but is also capable of printing independent items in separate lists, one or more of which are to be footed or totalized and the others not, as in the practice of billing or making out statements for different classes of goods with certain indicating-marks which are not to be accumulated, followed by amounts or values which are to be accumulated.
