ACCOUNTING-MACHINE Specification of Letters Patent Pabenfiefl Ngv, 22 19111 Application filed ere 26, 1909.' Serial No.280,178.

automatic manner, the envelops being automatically discharged as they are printed upon. ment of this character is shown applied to the rear portion of a well-known type of adding and listing machine and so connected to the working parts of such machine that as the amount keys are manipulated to set.

up different amounts and the. handle of the machine is pulled or the machine is otherwise operated in a familiar manner, envelops stacked in'a suitable runway are successively taken from the stack singly, presented with the desired portion confronting the type, held at such position so as to receive an impression from the type, then discharged and finally 're-stacked.

With the aboveobject in view the invention. consists in certain novel .featurcs of construction and combinations of parts, the

essential elements whereof are recited in the appended claims and a preferred form of embodimentof whichis described in detail hereinafter and fully illustrated in the ing such as obtain at the middle of anoperation of said machine, Whereas in Fig. 1 the various parts are shown at normal; Fig. 3 is a vertical cross section of the attach ment taken substantially on the line 3-3 of 'Fig. 2; Fig. 4 is a section taken substant1a ly on. the line 44 of Fig. 3; Fig. 5.is

In the present instance an attach arts of the adding and listing machine, t e conditions bean enlarged detail section talren on line 5-5 of F 1g. 2; Figs. 6 to 10 are enlarged sections and illustrating thesuccessive steps in handling the envelops; and Figs. Hand 12 show an envelop before andafter treatment. It will not be necessary to describe in detail the adding and listin machine here shown but reference may he had to Burroughs Patents 5%,963 and 505,078,'issued September 12, 1893. It is to be understood that this is merely chosen as one of several types of adding and listing machines and that the invention is adaptable to other types. It is proposed. in the present embodiment of the invention to apply the attach-- aper carriage is ment where ordinarily a mounted. Thus a supportlng plate .9; is secured across the back of the machine, being suitably bolted or otherwise attached to the main framework 3 of the machine. There is seouredwto this plate projecting rearwardly therefrom a box 4 here shown as of considerable depth and rectangular in cross section. The lower portion of this box 0011-, stitutes a runway for envelope stacked with ends resting on the'bot-tom of the'hox as shown in Fig. 4t. An opening 5 is provided in one side of the box as shown in Fig. 3

through which to introduce the envelops in packages. They can be so introduced with the usual bands (in-them and such bands broken and removed after the packages of envelops have been stacked in the box. A plate 6 (Fig. i) is mounted to travel in the box as a follower for the similar to the right-hand portionof Fig. 4

stack of envelope, constantly thrusting the same forward. Said plate is preferably equipped with rollers '7 to run on the bottom of the box and reduce friction. The plate has ears 8 (Fig. 4-). overlying ears 9 on a head 10 of a lunger rod 11, and a swivel pin 12 extent through the ears and said plunger rod, connecting the follower and the plunger rod so as to allow for pivotal movement of the former to compensate i'or irregularities in the envelops and provide for close engagement between the follower and the rearmost envelope and .for uniform pressure tending to. advance the stack of envelops. The lunge'r rod 11 is here shown in theform "ol a channel bar. but may of course take various forms. There is secured to its rear end, which rotrudes from the box, a cable 13 running orward overasheave or pulley 14 and having suspended on it a weight 15. Saidsheave or pulley is supported in a, suitable bracket 16 secured to the back of the'box and it will be obvious that the weight acts to constantly thrust the follower 6 forward, forcing the envelops to the forward end of the box as long as any of them are contained in the box.

Mounted on the front side of the box l is an envelop lifter which is in the form of a rectangular plate 17 confined in a vertical slideway formed in the rear side of the supportin plate 2, the box at not havinga front side-0t its own but partially closed at the front by said supporting plate. The lifting plate 17 is thus presented to the first-envelop of the stack in the box and such envelop will be closely pressed against said lifting plate. The latter is thickened along its lower edge and formed with a ledge or shoulder a, and the bottom of the box -lis cut out so as to provide for the thickened portion of the lifter plate passing down throughsuch bottom until said ledge or shoulder is flush with the upper surface of the bottom of the box as shown in Fig. 7. Normally, however, the lifter plate is elevated as shown in Fig. f so that said shoulder or ledge is considerably above the bottom of the box, as shown in Figs. 4, 6, 8 and 10.

In the upper forward portion of the lower division of the box which contains the stack of envelops there is mounted a stop bar for preventing any but the foremost envelop rising. As here shown this bar comprises a head 18 and a shank 19, the latter bifurcated to embrace a cross rod 20 supported in the sides of the box. This shank contains a spring-pressed plunger 21 bearing against said cross rod, the spring acting to thrust the stop bar forward. The head 18 of the latter is also bifurcated and embraces the central portion of a shaft 22. The lower forward corner of the head 18 is slightly chamfered onrounded off so that the foremost envelop when lifted by the plate 17 may enter the bite of a pair of feed rollers 232 l, the latter carried by the shaft 22. The spring applied to the plunger 21 is comparatively light so that it may yield when the said envelop is lifted and as it is carried up by the feed rollers. Frictional, engagement between this and the next en velop is prevented from causing such next envelop to rise, by reason of the obstruction offered by the head 18 in advance of the up er edge of such next envelop.

t will be later explained through what particular means motion is imparted to the ifter plate through the operation of the adding and listing machine but it may now be stated that with the latter at normal the lifter plate is elevated and a blank operation of the adding and listing machine will condition is illustrated in Fig. 4.

'27 towardthe roller 28.

lower the lifter plate so that the foremost envelop will thereupon engage over the shoulder or ledge a and then said plate will rise so as to carry the foremost envelop up into the bite of the feed rollers 23-2l, which At this time said feed rollers are in motion so that they'take hold of the envelop and at the coin clusion of the blank operation stand ready to further raise the envelop. Fig; (3 illus trates the condition when jthe machine is at normal and a stack of envelops is put'into the box and the follower released'so that it is pressing the stack forward. Fig. 7 illus trates the condition shortly after the commencement of the blank operation of the adding machine. Fig. 8 illustrates the con-i dition at the conclusion of such blank operation. A in each of these figures designates the foremost'envelops.

In ensuing operations of the adding machine in which the amount keys 221 (Fig. 1) are manipulated and the shaft 300 oscillated by the drawing forward and release of the usual operating handle or otherwise, the envelops will be brought one at a time to position for receiving impressions from the type plates 618. In the box 4: just above the stop bar 1819 there is journaled a platen roller 25 (Fig. 4) located to back up the envelop ..when the type plates 618 are drivenagainst it, it being understood of course that a suitable inking ribbon intervenes. The supporting plate 2 is open in front of said platen roller and there project from the sides of the opening suitable guiding clips-26 behind which the envelop passes when advanced to printing'position by the feed rollers 2324-. In' line with the said feed rollers and located above the printing line are similar feed rollers 27-28, the

latter secured to a shaft 29 journalett in the sides of the box fl. There are here shown two feed rollers 23 and two feed rollers 27 and the feed rollers2 l and 28 are of sectional construction as shown in Fig. 3

uncovering the

shafts

22 and 29 for a space at the middle of each. Thus there are ina sense four pairs of feed rollers, two at each side. The feed rollers 23 are journaled in springs 33 or causing said rollers 23 to be pressed yieldingly toward the roller 2- The upper rollers 27 are journaled in arms 34: loose on a cross rod 35 supported in the sides of the box 1, at the upper forward part thereof. Spiral springs 36 extend between studs 37 on said arms 34 and the screw studs 31, said springs serving to press the rollers The arms 34 not only serve to support the rollers 27 but also act to deflect the envelops as they are fed into raised andthe foremost envelop brought be-' the upperpart of the box 4 by the feed rollersas indicated in Fig. 4, said arms being inclined rearward.

It has before been stated that normally the lifter plate 17 is elevated and it has been further'explained how, in a blank, operation of the machine, said plate is lowered and tween the feed rollers 23 and 24: to the posi tion shown in Fig. 8. In an ensuing operation of the adding machine said feed rollers will be turned sufliciently to carry the envelop up between the platen 25 and the type or to the position illustrated in Fig. 9,the upper edge of the envelop being then in the bite of the rollers 27-28. The envelop remains at this position until the printing has taken place. Then during the return movement of the adding machine handle or re turn rocking of its drive shaftythe feed rollers .23 and 24- are further turned and also the feed rollers 27-28 so that the envelop will be carried upward to the position shown in Fig, 10 .or until its lower edge has moved beyond the printin line. Then when another operation of t i eadding machine starts the feed rollers 27-28 again move and dis charge the envelop, another meantime being brought to the printing position. The arms 84 deflect the envelop as it is discharged by the rollers 27-28 so that it will fall backward withthe printed side uppermost.-

The platen roller 25 is grooved, at each end to receive bands or belts 38 which engage similar grooves of a 'pulley 39 journaled between arms 40 Which at their forward ends loosely surround the platen roller shaft 41. These last-described parts constitute airendless con'veyeruponwhich the envelops fall when discharged from the upper feed rollers. The upper stretches of the conveyor belts travel rearward so that the printed envelops are moved toward the back otthe box at. Here the box is formed with an incline 42 up which the rearmost envelop will slide so that the latter eventually assumes a partially upright position as shown in Fig. 4, following envelopslsliding'up on each other so that the envelops will be stacked after having been printed. The arms to are connected by suitable cross rods 48 and normally extend horizontally resting upon pins 44 which roject from the sides of the box. The endless conveyor thus. di vides the box into upper and lower compartments but if desired to gain'access to the lower compartment through the top of the box the conveyor can be raised swinging on the platen shaft 41. This may be found more convenient at times when introducing a large number of envelo into the runway, as compared with intr ucinga bundle at a time through" the said opening 5.

It remains to describe the means here shown for imparting movement to the lift plate 17, the teed rollers and the roller platen. thesevarious parts takes the tormot a lever having a segmental portion 50 above its pivot (see Figs. .1 and 2) and an arm 51 below its pivot, the latter pivotally connected to a link 52 which extends through an The main .op'eratin member for i opening in the supporting plate 2 and is formed at its forward end with jaws 53. The latter embrace a wrist pin or shaft 54- carried by crank arms 110' secured to a rock shaft 100. This shaft and itsarins 110 as well as the wrist pin or cross shaft 54 are all familiar parts of the Burroughs adding and listing machine and it will be understood -that they oscillate in each operation of such machine. Hence with the jaws of the link 52 engaging the shaft ,or wrist pin 54, the

lever505l will be vibrated every time the machine is operated. This lever is suitably pivoted between the side of the box 4 and a bracket 57 projecting from the supporting plate ,2, and has fa forwardly-projecting prong 56 normally engaged with a stud 58 (Fig. 1) on a strip or bar 59 slidably mounted upon the supporting plate-2 as shown in Fig: 3. Said strip or bar is there shown as formed with laterally turned end portions, the upper one of which is slotted to receive a screw 60 and the lower one of which is connected by a screw stud 61 witha lever 62 mounted on the front side of the plate 2,

said screw stud extending through a slot in 17, said studs 63 working in a vertical slot of-t'he plate 2 (Figs. and t). I

As the handleot the adding machine is pulled forward it will be obvious that the accompanying rearward swing of the crank forward movement of the operating handle.

There is formed in the segmental upper. portion 50 of the driving lever an oblique slot 70 the sides of which act with a camin'ing efiect upon a roller on the end of one arm ofa' bell crank lever 71 pivoted on a stud projecting from the side of the box 4 and carrying pivoted to its other arm an elongated pawl 72. The latter is adapted to act upon pins 73 yrojecting from the side of a gear wheel 74. the latter journaled upon a stud 75 which is secured to the side of the box a .(see Fig. 5). A spiral spring 76 congear wheel is further rotating.

It will be seen that rocking of the lever 51 caused by pulling the operating handle of the adding machine forward will rock the'bell crank 71 in a direction to advance the pawl 72. Normally the acting edge or shoulder of the pawl stands a little in rear of one-of the pins 73. Consequently as the operating handle starts the pawl moves up to said pin and in continued forward movement of the handle acts upon said pin to turn the gear wheel 74.. The latter is in mesh with pinions 78 and 79 on the

feed roller shafts

22 and 29 so that-this movement of said gear wheel causes turning of the feed rollers in a direction to carry the envelop upward. The measure of this movement is such as to take the envelop to the printing position illustrated in Fig. 9. Here the upper feed rollers 27 and 28 do not act upon the envelop but the

lower feed rollers

23 and 2 alone perform this function, carrying the upper edge of the envelop into the bite of the upper feed rollers. It will be understood that this assumes a blank operation of the machine to have previously been made with the result before explained, to-wit, that of lifting the foremost envelop of the stack into the bite of the lower feed rollers, the latter having taken hold of the envelop as illustrated in Figs. 6, 7 and 8. Of course in such blank operation the upper feed rollers are performing no work.

It will be understood that at the conclusion of the forward movement of the operating handle rinting takes place, amount keys 221 having been depressed before the handle is pulled. There is a short dwell at the lower end of the cam slot 70 which provides for the gear wheels remaining stationary and the envelop consequently being immovable during the printing.

A gear segment 80 is formed upon the upper portion 50 of the driving lever and this gear segment is in mesh with a pinion 81 journaled upon the stud (Fig. andsecured to a ratchet wheel 82 mounted alongside of it. A pawl 83 is pivotally mounted on the side of the gear wheel 74 and spring-pressed into engagement withsaid ratchet wheel (Figs. 1 and 2). During the rocking of the driving lever already described the pinion and ratchet wheel are turned in the direction of the arrow in Fig. 1 so that the teeth of the ratchet wheel simply click ast the pawl. Upon the reverse rocking of the driving lever, however, which accompanies the backward swing of the operating handle, said ratchet wheel drives the gear wheel 74: through the medium of the pawl 83. This turning of the gear wheel rotates the feed rollers so as to carry the printed envelop up to the position shown in Fig. 10, the lower feed rollers first acting in conjunction with the upper feed rollers to pass the envelop along and the upper feed rollers then acting to carry the envelop beyond the printing position. Meantime the prong 56 rises and acting upon the stud 58 elevates the lift plate 17, raising the next envelop into the bite of the lower feed rollers and the rotation of the latter having continued they take hold of this envelop, moving it to the position shown in F ig. 8. To prevent overthrow when the gear segment comes to the end of its return movement after driving the gears in the manner described, there is loosely mounted upon the same stud which supports the bellcrank 71, a pawl 85 which is swun spiral spring 86 (Fig. 2) but moved against the stress of said spring by contact of the driving lever with a stud 86 on the arm of said pawl which depends from its pivot (Fig. 1). This rocking of the pawl by the driving lever engages its notched end with one of the pins 73 of the gear wheel 74:-

which obviously prevents any overthrow of the latter. The lost motion between the pawl 72 and the pins 73 on which it rests provides for the unlocking of the gear wheel before said pawl acts upon said pins.

in the next ensuing operation while the lower feed rollers are advancing'the next envelop to the printing position the upper feed rollers discharge the printed envelop, the latter being deflected by the arms 34 and falling backward onto the conveyer. As one operation after another takes place the printed envelops thus discharged upon the conveyer are carried rearward by the same and eventually the first envelop strikes the boxincline as, (Fig. 4). The envelops will lie one upon another at different inclines as the operations proceed so that they are stacked in the upper compartment of the box in regular order.

Means are provided for turning the roller platen step by step for the purpose of intermittently actuating the conveyer and also for the purpose of distributing the wear .on the .platen. Thus there is secured to the right-hand end of the platen journal a ratchet wheel 90 (Figs. 1 and 2) which is engaged by a tooth 91.0n an arm 92 pivoted intermediate its ends to a crank arm '93 which is rigid with thedriving lever. A spiral spring 94 connects the lower end of said arm 92 with a stud on the side of the box 4, said spring holding the tooth 91 in engagement with the ratchet wheel. The latter has an odd number of teethtwenty-one in the present insta'nceand the tooth 91 Or rearwardly by a erases has a throw of an even number of teeth,

in the present instance 4. It will be chduring the further movement of the operating handle but comes to a close just as the hammers of the adding machine are fired.

It will be'obvious' that the intermittent turning of the platen roller moves the conveyer belts in a direction to carry the printedv envelope rearward. I

It is suflicient for the upper pressure rollera 27 to simply bear upon the companion rollerv sections 28 but as the lower set of "feed rollers have more work to do in extract ing the front envelop from the stackagainst the friction between it and the next envelop,

it is preferable to gear the slower feed rollers together. To this end the shaftQQ carries small gear Wheels95-96 which mesh respec tivelywith similar gear Wheels 97, 98 on the pressure rollers 23 sothat the latter are respectively driven .and do not rely simply upon friction engagement with the envelop to receive rotary movement. 4

A machine equi ped as above described will be found use ulin many'connections, but it will suliice to refer specifically to one, to-wit, its use in a paymasters office. In

this connection the attachmentmay be assinned fo'r'example'tobe on a machine such as that shown in Vincent Patent No. 908,430, issued December 29, 1908, where provision is i made for splitting or subdividing the printing mechanism, and extending the total to the adding Wheels associated with the lefthand section or subdivision.- Envelops will r be stacked in the lower 'compartment of the box 4 with the sides to be printed '(Fig. 11)
