ADDING MACHINE.

7 T 0 all whom it may concern:

Be it known that I, 'Hnman C. Pumas, a citizen of the United States, residing in the cityg county, and State of New Kerk, have invented certain new and useful Improvements in Adding-lllachines, of which' the following is a specification.

My invention relates to adding machines and the like, capable of printing, listing and adding or accumulating individual items or f amounts and of printing the total thereof at the will of the operator, such type of ma chine being exemplified by the well known- Burroughs adding machine, made substantially in accordance with Letters Patent of the United States-Nos. 504,968 and 505,07 8, issued on September 12, 1893, on the invention of \Villiam S. Burroughs.

as hereinafter described, the total'is automatically taken during a second blank or spacing operation of the machine, that is during a second blank stroke or movement of the main operating machine or of the operating handle, if a handle is employed as the means for operating the machine. The usual total key or button may thus be dispensed with and the total taken by a plurality of operations of the machine which would ordinarily be blank or spacing operations o-r strokes of the machine.

f In the present instance, for the sake of a clear and definite description and understanding of my invention, I have illustrated and will hereinafter describe the same in connection with a Burroughs adding machine, but it'will be understood that my inventionis not limited in its application and' scope to such particular type of machines,

but that it may be employed in connection with or embodied in adding machines of the same general character and used for the $211119 general purposes.

In the drawings, Figure 1 is a side elevatlon of the right-hand side of a Burroughs ing on the shaft 400.

Application filed April 29, 1905. Serial No. 258,088.

adding machine illustrating only those parts of the ordinary machine which are necessary to an understanding of my inventiong-Fig. 2a view similar to that of Fig. 1; but'of the left-hand side of themachine; Figs: Site 6 detail views principally of my "improvements or attachments showing diiferent posit-ions thereof.

Briefly describing these parts of a Bur roughs machine which are more or less directly concerned with the operation of my improvements or' attachments, the keyboard is provided as usual with a series of keys arranged in rows representing the differentdenominations increasing from right to left and each row containing keys 291 representing the digits 1 to 9. .Uponthe depression or operation of any one of the keys on the keyboard the sliding plate or plates 214 corresponding to the row or rows of "thekeys which have been operated are moved rearwardly, with the result that the projection or lug 214 depending from such sliding bar will rock the bail composed of'the universal bar or rod 209, extending transx'ersely of the machine, and the parallel side arms 4-24 rock- This "longitudinal movement of any one of the sliding bars 214 will operate to rock the detent 4:15 corresponding, thereto and thereby release its corresponding rack 610, which is thereby permitted to move downwardly between the plates 210 a distance as permitted by the particularone of the stop rods 270, which may have been operated, this movement or descent ofthe rack corresponding in" value to the value of the particular key operated or depressed. The racks 610 correspond in number with the number of rows of keys and cooperate with a corresponding number of adding wheels 912 which are each provided with a pinion 916 meshing with said racks in a manner hereinafter explained; The

racks are carried at the forward ends of a series of main levers or bars 611 pivoted intermediate of their length on the main transverse shaft 600 and carrying at their. forward ends the movable type 618. As is well known, the rearward or type bearing ends of the main levers, that is those levers corresponding to the rows in which any key may have been operated, are elevated, in the operation of the machine, a distance corresponding to the degree of descent of their respective racks 610, with the result that in composed essentially of the side or end I pitman will be reciprocated parts of the machine and just before the set up on the keyboard.

the further operation of the machine and the actuation of the printing mechanism, the amount or value indicated by the depressed keys will be printed upon the paper on the platen and in the subsequent restoration of the parts of the machine such amount or value will be accumulated on the adding wheels or dials.

Describing next the totalizing i'nechanism employed for taking a total, either a grand total, or a subtotal, and referringparticularly to Fig. 2 of the drawings, the adding wheels are mounted in a swinging frame plates 91.0 which are pivoted upon the main cross shaft 900. l"his-a(ldin wheel or pinion frame is rocked forwardly and backwardly at the proper times in the operation of the machine so as to cause engagement and disengagement betwcemthe racks and their respective pinions. In accumulating items, the pinion frame is swung forwardly upon the initialmovement of the main shaft 300 of the machine and the racks, that is the racl's corresponding to the particular keys which have been operated are permitted to descend while out of mesh with their pinions. Upon the restoring movement of the racks begin their upward movement, the pinion frame is swung rearwardly' and the pinions put into mesh with their respective racks, with the result that an amount or value is transferred to the pinions whose racks have been operated, such amount or value corresponding to the value or amount- Each item or amount. is thus added or accumulated on tlr. pinions and wheels. In a Burroughs machine, this rocking movement of the pinion frame is ln'oug ht about through the medium of the bifurcated pitman 914a operativcly connected to the three-armed lever or. plate 913, which tself rocked by means of the rocking arm 01 lever 813 secured to the main rock shaft 800 of the machine. As is well known, the lever 913 is rocked through the medium of the-wipe plate 821 ivotcd on one of the arms of the rocking lever 8 3 and arranged to cooperate with the pins or studs 961 and 961 on the lever 913. The arms or forks of the pitman cooperate with the pinion frame 910 for rocking the latter in the we-lllniown wa; and for the purposes above stated and it will sutlice to say that upon the initial movement or rocking of the main shaft 800, the pitman 914: is moved forwardly, that is to the right in Fig. 2, with the result that the pinion frame 91.0, through contact of one of the arms of the pitman with the stud 9.38 will be rocked forwardly, but upon the restoring movement of the main shaft and'of the rock shaft 800, the. in the opposite the pinion rame with it direction, carrying and causing its pinions to again engage with their respective racks for the purpose of accumulating the amounts or values rcprescntcd by thoseracks which have been operated. Heretofore, in taking a total, a total key or button has been employed for the purpose of controlling the movements of the totalizing; mechanism described, such total key or button having been connected with the pitnian 9H, through the medium of the link 911, with the result that when the total key or button was operated or depressed the pituian 91d was removed from its operating connection with the pinion frame 910 through the medium of the stud or pin 958, with the result that upon the initial movement of the main shaft of the machine and the descent of the operated racks, the pinions would remain in mesh with their racks, and the latter would descend distances corresponding to the accumulation or total indicated by the adding wheels, thelatt'er being stopped at zero position by contact of their transfer projections against the feet. of the transfer pawls as usual) and after such total had been printed, the pinion frame would be swung forwardly, thereby disengaging the pinions from their racks and permitting the latter to be restored to normal position and leaving the adding wheels at their reset or zero position. Upon the completion of the operation of the machine the-pinion frame swung forwardly to its normal position. The totalizing operation just referred to is that for taking a grand total, but in taking, a sub-total (referring to the ordinary Burroughs machine) the total key or button is released at the end of the forward stroke of the main shaft of the machine, so that upon the return movement of the racks, their piuions are left in mesh, with the result that the amounts or values which were transferred from the pinious to the racks will now be re-transferred to the pinions and their adding wheels. I

In the operation of taking a total an arm 227i secured on the transverse shaft 20- (which arm has heretofore been made in the fi'lrm of a bell crank connected with the total key) is moved or rocked rcarwardly as to its lower end for the purpose of reciprocating the link 21.611 which, together with the similar link 216R. on the right-hand side of the machine carries the transverse or universal rod 209 serving the purpose of rocking the series of detents 415 and thereby releasing all of the racks' This arm 227L also serves to reciprocate the bar 226, for the purpose of resetting the keys, but as this part of the machine is not concerned directly with the operation of'my improvements, the same need not be further described.

The parts hereinbetore described are hose which are usual and well known in the ordinarv Burroughs machine, to which I have chosen toapply my invention forthe purpose of a comprehensive description.

In general terms, my invention provides means under the control of the machine in its operations for accomplishing, in an automatic manner, the same results heretofore accomplished by themanual operation or manipulation of a total. key or button, such automatic operation, in the present instance,

. justment of the totalizing mechanism.

Referring to the new parts or attachments, 1 provide a link or bar 1, which is normally substantially m a-hnement with the link 216R and having a pin and slot connection with the lower end of the rock ing arm 227R, in the present instance such link or bar having a longitudinal slot 2 received by the stud 263 at the lower end of the rocking arm 227R. At its rearward end, the bar 1 has a pin and slot connection with a rock arm 3, which is secured upon the rock shaft 801. Inrthe present instance, the bar 1 has a longitudinal slot 4 toward its rearward end and adapted to receive the pinor stud 5 carried at the outer or forward end of the rock arm' 3. In order to rock the rearward end of the bar 1 upwardlyfor the purpose hereinafter made apparent and at the time any key on the keyboard is depressed, I provide means for rocking the shaft 801 simultaneously with the operation of any one of the keys. To this end, in the present instance, I provide the rock shaft 801 with a crank arm 6, which is operatively' connected with the arm 424: by means of the link 7 extendingparallel of the sliding bars 214, with the resultthat whenever the arm 42%: is rocked rearwardly by the depressing of any one of the keys on the keyboard, the link 7 will likewise be shifted rearwardly and the rock shaft 801 rocked in a clockwise direction, Fig. 1, thereby rocking and elevating the outer end of the rock arm 3 and likewise elevating the outer end of the link or bar 1. It will be seen that this elevating or raising of the link or bar 1; as to its rearward end occurs only when one of the keys on the keyboard is operated, such operation being for the purposeof moving the link or bar 1 to an inoperative position so as to be removed from the rai'ige of the mechanisn'i hereinafterexplained'. The relative positions of the bar 1 and its rorlc arm 3 in their elevated condition is illustrated in Fig. 5 of the. drawings, their nornml'position being shown in Fig. 1.

It is evident that a swinging or rocking lions of the machine are performed, I proout the raising or elevating movement here- "of the depending arm 227R'rearwardly1as to its lower end will so set or position the totalizing mechanism on the left-hand side of the machine as to enable a total to bev taken and such rocking or swinging of this depending arm is brought about, in the present instance, by the link or bar 1 just described. It will be understood that whenever such link or bar is shifted or reciprocated longitudinally sufficiently to the rear of the machine to cause the outer end of its slot 2 to engage and move the stud or pin at the lower end of the arm 227R, such arm will be rocked in the manner and for the purposes already described. To accomplish this desired longitudinal movement of the bar 1 in an automatic manner when, according to the present embodiment of the invention, a certain number of.operavide suitable mechanism which, in the present instance, consists of the following parts: Upon a rocking plate 622, which is hung or pivoted upon the main transverse shaft 600 of the machine, I pivot an actuating pawl 8, which is normally spring pressed by a spring 9, to cause its outer or toothed end to coiiperate with the lower notched edge of the link or bar 1. However, this spring pressed movement of the pawl is limited by means of a pin 10. As shown in the drawings, the lower edge of .the link or bar is provided with two separate angular notches 11 and 12, with which the pawl 8. is arranged to cooperate under different condi tions or positions of the operating parts. The link or bar 1 is adapted, upon a blank or spacing operation of the machine, to be shifted rearwardly to a partial extent with inbefore referred to and is further adapted to be retained in this shifted position, in order, in the present instance, to enable the actnatingpawl 8 upon the'next blank or spacing operation of the machine, to engage the forward notch 12 of the linkor bar and thereby fully reciprocate or shift the latter in the manner hereinafter explained. To this end, I provide means for retaining the link or bar in its first or partially shifted position, such means, in the present in stance, comprising a dog 13 pivoted on the side frame of the machine and spring pressed by means of the spring 14 toward the lower edge of the link or bar 1, but 12 limited as to degree of swinging movement by means of a pin 15, as clearly indicated in Figs. 1, 3, 4 and 5. This dog is arranged to cotiperate with a third angular=notch16 located near therearward end of the link or bar, with the result that when the latter is shifted rear\vardly, as hereinafter explained, the same will be caught and retained against return movementby such dog 13, in the manner clearly 1lIdICatQd'lH Fig. 3, it being understood that such link or bar is normally spring pressed forwardly by means of a spring 17, secured to its forward end.

For the purpose of positively rocking the plate (322 by means of a moving part of the machine, I provide such plate with. an operating arm 18 pivoted upon the shaft (300 and forming a part of or separate from the plate (322, but arranged to positively rock the latter when it is itself rocked. This operating arni depends in the path of movement of a cam plate 311 which, in the present instance, is operatively connected with the usual sector 31 but which may obviousl} constitute an integral part of such sector it desired. The lower. end of the operating arm 18 normally bears against the forward or inclined corner of the am ilate 31.1. with the result that when the cam plat and sector is rocked in an anti-clockwise direction at the initial operation of: the machine, the operating arm is quickly rocked in a clockwise direction, but owing to the. illustrated contour of the remainder ol the cam face, the operating; arm is not rocked after its initial rocking, but the sector is permitted to complete its toiwvard rockino' niorement without :turther etleet upon the operating arm. The result of this rocking of the operating arm and the consequent rockingoi the plate 622 is to cause the actuating'pawl 8 which nor-mall enthe notch 11 to move the link or bar rearwardly to such a position as to be caught and retained by the dog 13, it being understood that the assumed stroke or operation of the sector is what is generally known as a blank or spacing stroke, at which time no keys on the keyboard have been operated or depr ssed, with the result that the link or bar has not been elevated, but. has been left in position to be engaged by the actuating pawl S in the manner just described. The position of the link or bar 1 at the end of the first blank 'or spacing stroke is illustrated in Fig-,2 th the pin or stud at. the lower end of the depending arm 227R being positioned near the outer end of the slot ot the link or bar, with the result that when tl e latter is further shifted in a rearward direction, such depending arm will be rocked for the plll'pOFjO of bringing the totalizing and clearing mechanisms inproper position "for the taking of a total or the clearing of the machine. Referring more particularly to Fig 3 of the drawings which illustrates the relative position of the parts at the end of the first blank or spacing stroke or operation of the machine, itwill be observed that upon the second blank or spacing stroke or operation of the machine, the cam plate 311" will rock theoperating arm 18 and the actuating pawl 8 in the same manner as before, but at this t me e c iactuatingpawl has already taken its place in the forward notch 12, due to the fact that the dog, 13 held or retained the link or bar 1 in its rearward position to which it had been shifted onthe fiustblank stroke or operation of the machine. Upon the rocking of the arm 18 and the consequent rocking of the actuating pawl 8,,the link or bar will be shifted rearwardly to its full extent in the manner illustrated in Fig. 4, with the result that the depending arm 227R which controls the position of the totalizing and clearing mechanisms has been rocked rearwardly and at the saine time the series of (letcnts 115 have been rocked by the universal bar as to release all of the racks. Owing to the illustrated contour of the cam plate 311", the linkyor bar 1 is operated quickly at the initial movement of the sector 311 and its operating shaft 3 O, to which it is connected so that the totalizing or clear-- iug' mechanisms are properly set or adjusted for the totalizing or clearing operations in advance of the other operations: of the machine, which take place in the further movements of the operating: shaft.

According to the macnine as so tar described, the total which will be taken as above explained will be a grand total a d the machine would be cleared after such total had been taken. llmvever, to enable a sub-total to be taken upon the second blank or spacing operation of the n'iachine, 1'. pro vide suitable means tor preventing the rocking or swinging ot the pinion frame 910 forwardl upon the return movement oil the main operating or rock shal't 300, with the result that the adding wheel pinions will be kept in mesh with their racks upon both the descent tlltl return of the latter, so that the accumulation or total. atter being printed, will be transferred back to the add ing wheel pinions in the usual and well known manner, In the present. instance. l accomplish these results by interfering with the operation of the wipe plate 821 upon its return movement. and. thereby prevent the same from engaging the pin 961 and from rocking the arm or plate 913. According to the present embodiment of my invention in this respect, as clearly illustrated in Fig. (3, I take advantage of the movements of the usual error ke 293E and its operating connections consisting of the bell crank 2271/4, the. link 2201/2, connected to the side arm 919R of the bail for restoring the keys, which bail rocks as usual on the shaft 207; At the left-hand end of the shaft 207 the end of the bail is formed as a bell crank 2191i, whoselower or forwardl i ex: tending arin 21$) is arranged to rock downwardly at every depression of the error key to the position indicated in. dotted lines in Fig. (5. At the outer 'end of this arm of the hell rank is pivotally connected a depending bar or strip 19 which is of such length andmarranged in such relative position to be projected into the path of movement of theliwipe plate 821 whenever the error key is depressed, as indicated in dotted lines in itfaiidal ligrfi. To guide and support this bar th 'machine is operated twice without any akeys being:operated, that is, two blank or spacing" strokes are taken, the total being taken and printed and the machine cleared automaticallyanez'cly by reason of such p u- 5 l'alitiy dfblank or hl'HlClllQ strokes or operaetions of-the-nrachine flVhen, however, it is idesiied to simply take a sub-total, the error-keyis depressed as above explained, lerrtointerfere with one of the funct.i(1'=1=is- -r)f the wipe plate and the two vLstr'nke rioperations of the il'tfltlllllt. are

tomeans t'or au'tomati- My invention also contemplates means, under the control of the operator, for rendering the automatic total mechanism inoperative in ord r that blank strokes or operationsof the machine may be taken, as for spacing, without causing an operation of the automatic total or clearing mechanism. In the present instance .I utilize for this purpose the repeat key 215 and its bell-crank connection 218 which is fulcrumed upon the rod or shaft 208. Upon this bell-crankQlS I provide a stud or pin 218 which is arranged in the path of movement of the link or bar 1 of said automatic mechanism, with the result that when the repeat key is depressed the link or bar 1 is raised or rendered inoperative in the same manner-as when any one or more of the value or number keys are operated or depressed. usual, this re )eat key is provided with means for locklng the same in operated position so that after one operation or depression thereof as many blank strbkes as desired may be takenwithout operating the automatic total or clearing mechanism. in the present instance the bell-crank 2l8 oi? the repeatkey mechanism cooperates directly with the ,pawl (323 for the purpose of interfering wi h the action of the latter and thereby preventing the restoring movement of the arm 219R which when operated rcstores the sliding bars 214 and permits the operated keys to return to normal position. For this purpose the hell-crank 218 IS provvided near its rearwardend with a stud or means of the spring (388v against; whose tension the stud 218" holds such pawls in the interfering position just described.

It will he understood 't'rom'the foregoing description that my automatic mechanism maybe rendered inoperative at the will of the operator by simply operating the repeat'. key. When the repeat. key is permitted to be restored to normal [)OSltlOll, the link or bar 1 is also permitted to be restored to nor-- mal position. l\l01eover, it will be understood that my inventioncontemplates and covers broadly mechanism for the autmuatic taking of a total, either a grand total or a sub-total, or both, and regardless ot whether it is the tahingot the gramltotal or ,lllt-E: subtotal which requiresthe'scttlng or operation ot? a specialkey'.
