9 Claims. (01. 235-60) This invention relates to a calculating machine and it is concerned with an improvement for making such machines more automatic.

An item is indexed on a key set calculating machine by depressing the amount keys. During a cycle of operation of the machine, as for example, a total taking cycle, these keys are ordinarily locked against depression. However, after an operator has depressed the total key and the motor bar for a totaling cycle, he may be ready to index an amount in the machine-before the total taking cycle is completed. The present invention, in one of its aspects, is directed to providing a construction for enabling the operator to depress these amount keys prior to completion of the total taking cycle.

Ordinarily, in a key set calculating machine, when an item is indexed by depressing the amount keys, the keys remain latched during the major portion of the cycle of machine operation. During this cycle a differential mechanism, including actuators for the register, moves to differential position under the control of the depressed amount keys. a register is engaged with the actuators at the appropriate time, and, near the end of the cycle, the amount keys are released whereupon they return to normal. It is possible to keep the amount keys depressed through several cycles of machine operation by setting a repeat mechanism either by means of a repeat key or the paper carriage. A total cannot ordinarily be taken with the amount keys depressed because in total taking the actuators must move under the control of the register. If the amount keys were depressed, some or all of the actuators might be arrested by the stops controlled by the depressed keys rather than by the register. In fact, the total key is generally locked when an amount key is depressed.

It is sometimes desirable, however, to enter an amount, to take atotal. end to then reprint or reenter the same amount. While this could be done by a second depression of the amount-keys, the operation of the machine would be speeded up and the work made easier if the operator were not required to index the item a second time. The present invention is directed to a solution of this problem.

The general object of the invention is to provide an improved automatic calculating machine.

A more particular obiect is to provide a construction that will enable an operator to index an item in-the machine whilef-a total taking cycle is being completed.

mechanism for enabling a total to be taken from a register while the indexing means remains indexed for an amount that has been entered prior to the total taking operation.

Other and'more particular objects will appear from the following specification and drawings.

An embodiment of the invention is shown in the accompanying drawings, in which:

The invention is shown applied to a Burroughs high keyboard calculating machine whose construction is so well known that the present description of it will be confined to a general explanation and to the parts more particularly associated with the present invention.

General construction dexed in the machine, the keys being latched in position after being depressed.

An add-subtract register lie-Ii, sometimes called a crossfooter, is provided which can be connected to the actuators to perform addition,

subtraction, total and sub-total taking. The machine also has a pluraliy of multiple registers II which may be selectively positioned for cooperation with the actuators. The controls for the add-subtract and for the multiple registers are 0 described more particularly in Pasinski patents,

Nos. 1,778,506 and 1,911,768, to which reference may be made for details.

The actuators I! are carried on the ends of levers l8 pivoted loosely on the shaft l9, said Another object is to provide an improved levers being diiferentially positioned with the actuators. The rear ends of the levers l8 carry type 20 and, after the levers have been positioned, a printing mechanism, including the hammers 2|, is operated to drive the type against paper held around a platen 22.

Columnar printing is provided for by mounting the platen 22 on a traveling paper carriage 23 controlled by a tabulating mechanism 24 which is normally operated during each machine cycle to tabulate the carriage from one column to the other near the end of the cycle.

The paper carriage is employed to automatically condition the machine to perform predetermined functions, and one of the functions that may be thus controlled is that of total or subtotal taking from a multiple register as described in Muller Patent 1,854,216. Briefly, the carriage supports a roll 25 operating on a yoke 26 which transmits movement through the connections 21, 28 and 29 to a total taking lever 30. In predetermined columnar positions of the carriage the lever 30 may be moved or rocked clockwise from the position of Fig. 1 to condition the machine to take a total from one of the registers IT.

The machine may be cycled by hand or by a motor, portions 33 of a motor drive being shown in Fig. 1.

When an amount key is depressed from the full line position to the dot-dash line position of Fig. 2, it rocks a detent 35 clockwise against the tension of a spring 35 which normally maintains the detent and its key in underpressed position. The lower ends of these detents extend through slots 31 in slides 38, of which there is one for each row of keys. When a key is de pressed the rocking of its detent 35 moves its slide 38 rearwardly where it is latched by a latch 40 urged counterclockwise by a spring 4|. The latched slide 38 thus holds the detent 35 of the depressed key against return to normal and it also locks the undepressed keys of its bank and their detents 35, the slide moving under the lower edges of the detents 35 of the undepressed keys. Near the end of a cycle of machine operation, a restoring bail 42 releases all the latches l whereupon the slides 38 return forward to normal under the urge of springs 36 for the detents 35.

In order to be able to give the machine several cycles of operation with the amount keys depressed, provision is made for preventing release of the latches 40 for the slides 38, and this is done by controlling the movement of the restoring ball I! through the control of the pawl 44 that acts on said ball. The machine may be automatically conditioned for repeat operations by a repeat slide 45 controlled by the carriage through a roll "5, a pivoted yoke 41, and connections I8, 49, as shown in Muller 1,397,774. The automatic repeat mechanism not only controls the release 01' the keys, but it controls the cycling of the machine. When the paper carriage is provided with repeat rolls, the machine will go through a number of cycles automatically depending upon the number of rolls provided, and the keys will remain depressed.

Enabling a total to be taken while the indexing means remains indexed In the embodiment of the invention shown, the taking of a total with the indexing means indexed is made possible by temporarily removing the control of the actuators from the indexing means.

Referring to Fig. 1, the detents 35 which are rocked clockwise by depression of the amount keys are ordinarily connected to the index stop wires But in the present invention, the connection is such that the stop wires may be moved relative to the dctents under certain conditions.

Referring to Fig. 3, which may be taken as an illustration of a detent in the units order row of keys, the detent 35 is pivoted on a shaft 50. Pivoted loosely on this shaft is an arm 5| to which the stop wire H is connected. The arm 5| is urged clockwise by a spring 52 against a stud 53 extending from the detent 35. The spring 52 is strong enough so that, when the detent 35 is locked Clockwise by depression of the key it], the arm 5| moves with it and pulls the stop wire H to indexed position. An arm similar to the arm 5| is provided [or each detent 35, the arms [or the units row of keys being to the left of the dotents as viewed in Fig. 2, while those for the tens row are to the right as shown in said figure. The arms 5| for the two adjacent rows of keys extend downwardly through slots 60 (Fig. 2) in a slide 6|, there being one of these slides for each two rows of keys. The slots 60 are long enough and are normally positioned so that, when an amount key isdepressed. the corresponding arm 5| is moved against the rear edge of its slot 60 without, however, moving its slide 6 The control of the actuators by the amount keys, that is, by the indexing means, is temporarily removed, or disabled, by moving the slides 5| forward. This moves the arms 5| together with their stop wires forward, while the amount keys remain in position. The detents 35 for the keys which have been depressed, are latched by their slides 38. The detents 35 in rows where no keys are depressed are not latched but the stop wires H in said rows are already in their normal forward position. Since the slides 38 prevent the detents 35 in rows where keys have been depressed from rocking, movement of arms 5| for the keys of said rows stretches the springs 52, the parts moving to the relative position shown in Fig. 3.

Thus, by moving the slides 6| forward, all the stop wires II that may have been indexed by depression of the amount keys, are returned forward to normal where they are out of the paths of the actuators which may then be used for total taking under the control of the register.

In the embodiment shown, the slides 6| are moved forward by the total taking control means. As shown in Figs. 1 and 2, this total taking control means is that for the multiple registers II. The total taking lever 30 has a stud 62 operating in a slot 63 in one arm of a pivoted bell crank lever 64. The other arm of this lever is connected to an abutment slide 65 slidably mounted at its forward end on a stud 56. The forward end of this slide also carries a stud 61 operating against one arm of a bell crank yoke 63 pivoted on shaft 69. The other arm 10 of this yoke is connected by a link H to an arm 12 on a shaft 13 that extends across the machine. The shaft 13 has a number of arms 14 fixed to it which extend into slots in their respective slides 6|, there being, as previously explained, one of these slides for each two rows of keys. When the total taking lever 30 is moved forward, the bell crank 64 is rocked counterclockwise which thrusts the slide 65 forward and rocks the yoke 53-" counterclockwise to rock shaft 13 counterclockwise to move the slides 6| forward. Thus, as an incident to the conditioning of the machine for total taking, the control of the actuators by the ment of the registers with the actuators.

indexing means is automatically disabled. The total may then be taken, after which the total taking lever 30 moves back to its normal position shown in'Fig. 1. When the latter movement occurs the slides 6i move back to normal which causes the arms to move back to their normal position. The amount keys remain depressed, but after the total taking operation they are again in control of the actuators; The machine may then be given a cycle of operation during which the actuators will be differentially positioned in accordance withthe depressed amount keys and the item that was indexed prior to total taking may be again printed, and entered in the machine if desired.

Itis to be understood that, the interlock between the amount and the total keys is omitted so that the total key may be depressed while the amount keys are depressed.

Completely automatic control The conditioning of the machine above explained may be had by depressing a repeat key to prevent restoration of the amount keysand by depressing a motor bar for each cycle -of machine operation desired. Provision is made,

however, for completely automatic operation as follows:

Repeat cycles of operation of the machine are controlled by the repeat slide 45 (Fig. 1) heretofore mentioned so that, when an item is entered prior to total taking, and when the motor bar is depressed, the machine will go through a predetermined number of cycles depending upon the number and location of the repeat rolls on the paper carriage. In the total taking column the total lever 30 is automatically moved to total taking position as described in Muller No. 1,854,216. .But, in said patent it is necessary to depress the usual total key shown as T in Fig. 1 of the present case, in.- order to actually obtain the total. In the present machine depression of this total key is made unnecessary.

The depression of the total key T in taking totals from the registers is not for the purpose,

of controlling the engagement and disengage- That control is taken care of by the total lever 38.

The total key T is used to release the zero stops 88 (Fig. 2) that prevent descent of the actuators l2. These are all released ,.by said total key T in the standard Burroughs machine. In the present case, however. the slide 65 (Fig. 1) is provided with a stud 8| engaging the end of a lever 82 pivoted at 83. The other endof this lever engages one arm of a pivoted bell crank 84 whose other arm engages a stud 85 on one arm of a bail 86, that extends across the machine in front of the zero stops 80. Said stops 8!! have projections 8'1 (Fig. 2) adapted to be engaged by the ball 88.

The arrangement is such that. when total lever 30 is rocked forward, slide 65 moves forward, lever 82 rocks clockwise, bell crank 84 rocks counterclockwise, and ball 86 rocks clockwise to release the zero stops 88.

This makes it. unnecessary for the operator to do anything after he enters the item in the column immediately preceding the total taking column. this column, the machine is given a cycle during which the item is entered. Near the end of this cycle, the carriage tabulates automatically to the total taking column where the machine is automatically conditioned to take a total and When he depresses the motor bar in where it goes through another cycle automatically and takes a total, the control of the actuators by the amount keys, which remain depressed, being automatically disabled. Near the end of the total taking cycle, the carriage tabulates to the next column where it is given anothercycle automatically and: where the item is again printed or printed and entered, as the case may be, under the control of the amount keys that remained depressed.

Control by total key of main register As heretofore described, the invention has been explained in connection with the total lever for the registers 11. It will operate equally as well, however, with other function control keys. As an example, a modified form of construction is shown wherein the invention is associated with the total key T'for the main add-subtract regist'er |5l6. In fact, the invention will operate with both total taking controls of the same machine, that is, the lever 30 and the key T.

Referring to Fig. 4. thetotal key T, when depressed, moves the link 90 downwardly to condition the machine for taking a total from the main register l5-l6., This is the usual Burroughs total taking control means and a detailed explanation is unnecessary. The key T is on one end of a total taking bell crank SI the depressed amount key.

which carries a .stud 92 that, when the key is depressed, engages the cam edge 93 of an extension 94 of the yoke 68 (Fig. 2). This yoke controls the previously described link 1|, arm 12, shaft 13, arms I4 and slides 61 which, when the parts are moved, moves the stop wires II to released position to enable a total to be taken.

Thus, even though the amount keys are depressed, when the total key T is depressed, the stop wires ll corresponding to the depressed amount keys are moved to their normal released position so that a total may be taken without the actuators being arrested by said stop wires. When the total key is released, the stop wires move back to normal so that they are indexed in positions corresponding to the depressed amount keys and are in position to arrest the actuators during the next cycle of machine operation.

Early operation of amount keys during total taking operations The invention has been explained in connection with an operationofthe machine where the amount keysare depressed. to enteran item, the amount keys being held depressed during a total taking operation, after which the same item is againentercd or printed under thecontrol of The invention also has another use.

If no amountkeys are depressed prior to a total taking operation, nevertheless, a rapid operator may dcpressthe amount keys to enter an item 1 without awaiting the completion of the total taking cycle. the machine.

As already explained, when. the total lever 30 is moved to total taking position. or. when the total key T is depressed. thev slides 6| of Fig.2 are moved forward. Since no amount keys have This speeds up the operations on been depressed. the slides do not move any of the stop wires ll because such wires are already in their forward positions. but said slidesmove forward so that the rear edges of slots are against arms 5|. The stop wires are thus held forward. The total key, or the total lever 30,

as the case may be. is locked in total taking position during the total taking operation and, thus, the slides II are held in their forward positions during such operation. 11, while the slides I are held forward. some of the amount keys are depressed, the corresponding detents 35 will be rocked clockwise (Fig. 2) and such detents will be latched in position by their respective latch plates 38. Movement of the detents 35 does not ailect the stop wires ll, because the arms 14 hold the slides 6| forward and these slides hold arms forward, the rear edges 01 slots 60 bein: against arms 5|, as justexplained. The rocking of the detents 35 merely stretches the springs M (Fig. 3) between said detents and their respective arms ii. The amount entered on the keys is thus potentially indexed in the machine.

In order for the amount keys to be depressible during a machine operation, the interlock that prevents depression of said keys during a cycle of operation, as shown in Vincent 890,945, is omitted. The interlock between the amount keys and the total keys has already been omitted as previously explained.

At the end 01' the total taking operation and when the total key T, or lever 30, is moved back to normal, the slides ii are allowed to move rearwardly whereupon the springs 52 that have been tensioned by depression of the amount keys act to pull their respective stop wires to indexed position. Thus, the amount that was set up on the keys during the latter part of the total taking operation and potentially indexed in the machine, is completely indexed at the end of the total taking cycle so that the machine can immediately go through another cycle and enter th item that was indexed on the keys. A rapid operator may depress the amount keys while the machine is completing its total taking cycle and, upon such cycle being completed, can depress the motor bar and give the machine another cycle to enter the item.

It should be explained that, although, in normal operations of the machine, the amount keys that have been depressed are automatically released near the end of each machine cycle, the amount keys that may be depressed during a total taking cycle are not released by the machine at the end 01' such cycle. The release of these keys is effected by the bail 41 (Fig. 5) that is normally rocked i'orward near the end of the cycle of machine operation to release the latches 40 that release the latch plates 38 (Fig. l) This bail is rocked by a pass-by pawl 44 mounted on one arm of a three-armed member Iili on the rock shaft Ill. The repeat slide 45 has a ledge I06 which, when the slide is in a certain position, blocks the arm iiil so that the pawl 44 will not move down far enough to get behind the stud I01 on the end of the arm I", that moves ball 42. The repeat slide 45 is controlled by a carriage roll 46 acting through a yoke 41 and connections "-4! so that when the carriage is in a predetermined position the repeat slide 45 will be moved so that the ledge I08 will block the arm III as just explained. The result is that, during the latter part of the cycle, the ball 42 will not be rocked to release the key latches and the keys will be allowed to remain depressed. The machine is thus automatically conditioned so that, even though the amount keys may be depressed during the total taking cycle, such keys will not be released at the end of said cycle, but will remain depressed for the next, or succeeding cycle The repeat slide 45 normally also controls repeat machine cycles inasmuch as the arm I08 oi the ball 42 is normally, near the end of a machine cycle, moved sufficiently counterclockwise in Fig. 5 to engage the rear end of a slide I09 and move the latter sufllciently forwardly to disengage the usual repeat hook i I I) from the stud I II and thus permit the machine to stop at the end of the cycle. When the slide 45 is so positioned that the ledge I06 prevents the pawl 44 from rocking the arm I08 to release the repeat hook H0, the motor bar remains latched down at the end of the machine cycle and the machine then performs an automatic repeat cycle. When the mechanism herein disclosed is used to permit the operator to enter items on the amount keys during total-taking cycles of the machine, the repeat machine cycle is not wanted because the operator does not want a cycle of machine oper-- ation to start until the depression of the amount keys for entry of the item has been completed and, in such use of the invention, the usual repeat hook H0 is accordingly omitted.
