44 Claims. 1

This invention relates to accounting and similar business machines, and more particularly to the type of accounting machines used by banking and similar institutions, wherever, as a part of a business system, it is necessary or desirable to pick up data, such as an Old Balance, whether it be a debit balance or a credit balance, from records previously prepared, as an incident to the type of system used in the institution.

The invention is adapted to be used in machines of the general type disclosed in the following United States Letters Patent:

Bernis M. Shipley, No. 1,619,796, dated March 1, 1927; Bernis M. Shipley, No. 1,789,418, dated January 20, 1931; Bernis M. Shipley, Pascal Spurlino and Everett H. Placke, No. 2,262,253, dated November 11, 1941; Mayl A. Goodbar, No. 2,305,000, dated December 15, 1942; Everett H. Placke, No. 2,351,541, dated June 13, 1944; and Pascal Spurlino, Everett I-I. Placke, Willis E. Eickman and Arthur G. Kramer, No. 2,373,510, dated April 10, 1945.

Such records of the type mentioned in the first paragraph may be in the form of cards, sheets or tapes, etc., having thereon magnetic areas, or perforations, or printed or written characters designating the data to be picked up to be recorded in the machine embodying the present invention; and from such magnetic areas, perforations, or printed or written characters, definite data may be picked up, under control of the same, and recorded in said machine.

More specifically this invention relates to an automatically operated and electrically controlled keyboard, controlled by record cards,

sheets or tapes, etc., of the type above mentioned, wherein said prepared records control the selection of the various amount determining devices or keys, which selected devices or keys, after selection and upon automatic operation thereof, control difierentially adjustable devices to enter into the totalizers of the machine, and to set appropriate printing mechanisms in the machine, with the amounts corresponding to the values of the automatically selected and automatically operated manipulative devices or keys.

Moreover, the above mentioned keyboard is unique in its construction in that, in addition to its being electrically controlled and automatically operated, it can also be manually operated without in any way interfering with a previous or a subsequent automatic selection and operation of the devices or keys. Thus, variable amounts or data may be set up on the keyboard manually by the operator, or such variable amounts or variable data may be automatically picked up from record cards, sheets or tapes, and the devices or keys corresponding to the amounts or data picked up are automatically selected, and such automatically selected keys are also automatically operated whereby such amounts or data are entered into the machine through a differentially adjustable mechanism under the control of said devices or keys to transunit said data to appropriate totalizers and appropriate printing mechanism.

Such differential mechanisms, totalizers, and printing mechanisms, are disclosed in several of the above mentioned patents.

Only that much of said types of machines is shown herein as is necessaiy to properly illustrate the present invention, and for a more detailed description and illustration of such machines reference may be had to the patents above mentioned.

There are machines known wherein electrically operated devices have been superimposed above amount keys on adding machines, which devices are electrically operated for the purpose of depressing keys under control of perforated cards, to set up amounts corresponding to those represented by the perforations on the cards.

However, applicants invention is entirely different from that in this respect, in applicants invention, While the keys are automatically selected by electrical devices and are automatically depressed, such automatic mechanisms do not in any way interfere with the manual selection and depression of any of the same groups of keys. In the illustrated form the invention is applied to what are known in the art as flexible amount key banks, where, when manually operated the depression of any key in a bank releases any other previously depressed key in the same bank.

Thus, the machine to which applicants invention is applied may be operated automatically under the control of record cards, sheets or tapes, etc, having thereon magnetic areas or perforations, or printed or written characters, designating the data to be recorded in the machine. This same machine may be also operated by manual selection of keys and manual depression thereof to control the machine to record and accumulate data according to the manually selected and manually operated keys.

Therefore, it is an object of the present invention to provide a novel keyboard for a machine of the type above mentioned, which novel keyboard may be operated either automatically or manually.

It is another object of the present invention to provide a keyboard for machines of the type above mentioned, wherein the keys may be electrically selected and those electrically selected keys automatically depressed to control the machine to accumulate and record data according to the selected and operated keys.

It is a further object of'the present invention to provide a keyboard for types of machines above mentioned, wherein the keys thereof may be automatically selected and automatically depressed, or said keys may be manually selected and manually depressed for the purpose of controlling the machine to accumulate and record data according to the keys which have been either automatically or manually selected and depressed.

It is a further object of the present invention to provide a keyboard for machines of the above type, the keys of which are each provided with a movable device which is adapted to be automatically moved from a non-controlling into a controlling position under control of electrical devices.

It is a further object of the present invention to provide a keyboard of the type above mentioned wherein each key has a movable key pin connected to the armature of a solenoid such pin adapted to be moved from a non-eifectiv-e into an eifective position upon the energization of its associated solenoid.

A further object of the present invention is to provide machines of the type above mentioned with mechanism for performing a preliminary or auxiliary cycle prior to the regular machine cycle for the purpose of automatically selecting any of the keys and then automatically depressing the electrically selected k ys whereby those keys, after having been automatically depressed by means operable during the auxiliary cycle, control differential mechanism in the machine to accumulate and record data, according to the selected and operated keys.

It is a further object of the present invention to provide a machine of the above mentioned type and having the novel keyboard associated therewith, with means for performing a preliminary or auxiliary cycle prior to the regular cycle of the machine, and to provide means to prevent the regular machine releasing mechanism from becoming effective until substantially the end of the auxiliary cycle.

It is a further object of the present invention to provide a machine of the above type with a sin le motor having a plurality of clutch or driving devices operable by said motor, for the purpose of driving a portion of the machine throu h an initiatory or preliminary cycle, such preliminary cycle mechanism being driven by one of the clutches from the common motor. and at the same time preventing the other clutch from being o erated during the auxiliary cycle, and roviding for the release of the second clutching mechanism to drive the machine throu h its re ular cycle following the auxiliary cycle. which control mechanism renders the second clutch relea e mechanism effective near the end of the auxiliary cycle.

It is still a further object of the present invention to provide machines of the above mentioned type with a novel keyboard mechanism, the keys of which are adapted to be automatically selected under the control of cards, sheets or tapes, having thereon magnetic areas, or perforations, or printed or written characters, designating the data to be accumulated and recorded in the machine.

With these and incidental objects in view the invention includes certain novel features of construction and combinations of parts illustrated in a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form a part of this specification.

GeneraZ description Described in general terms, the invention invention includes novel keyboard mechanism for machines of the type mentioned at the outset of this specification, and particularly those machines which are ada ted to be used in banking institutions, other types of financial institutions, and as a matter of fact, wherever records are made where, as a part of the system of keeping those records it is necessary and essential that old balances be set in the machine to which new accounts are either added or subtracted, and finally the new balance is arrived at and a record made thereof.

More specifically the keys of each of the key banks of the keyboard, and particularly the amount key banks, are arranged to be electrically selected through means of a selective circuit closing device which functions to pick up the old balance from magnetic spots or perforations, or printed or written characters designating the carriage.

data to be picked up to be recorded, after which the selected keys are automatically depressed.

These selecting and depressing operations of the keys of the novel key banks all take place in what has been termed herein a preliminary or auxiliary cycle of the machine, which cycle is initiated prior to the regular operation of the machine during which regular operation the differential mechanisms, the printing mechanisms and totalizers are controlled according to the positions and values of the keys which have been automatically selected and depressed.

To accomplish the above purpose, and in the preferred form of the invention, the machine is provided with an electric motor and two clutching mechanisms which clutching mechanisms are adapted to be released in a predetermined timed relation so that one of them drives the machine through its preliminary cycle and the other drives the machine through its regular cycle.

It might be well to state here that during the preliminary cycle the main cam shaft and the differential mechanisms of the machine do not function, but are held in an idle position all during the preliminary cycle.

There are provided two separate clutch release mechanisms for the machine, but when the machine is released only the clutch release mechanism associated with the preliminary cycle is fully released to allow its associated clutch to drive the preliminary cycle mechanism. At this time the regular clutch release mechanism is held in an inoperated position by mechanism which is operated during the releasing of the auxiliary clutch mechanism, and is held in such idle position until substantially near the end of the preliminary cycle, at which time the main clutch releasing mechanism is rendered effective, whereupon the main cycle of operation automatically takes place immediately following the auxiliary cycle, without any other depression of keys or levers by the operator.

In other words, a depression of the balance pickup key or the overdraft pickup key closes a switching mechanism which completes a circuit to energize a solenoid, which trips the machine release shaft and releases the auxiliary clutch, and the motor starts.

At this time the card carriage, or table, such as that shown in the Shipley, Spurlino and Placke Patent No. 2,262,258, and also the Spurlino, Placke, Eickman and Kramer Patent No. 2,373.510, is moved into position. Upon this card carriage or table, there has been previously placed a cardor other type of control medium having thereon either magnetic areas or perforations, or printed or written characters, designating the balance which is to be picked up, and the selective circuit controlling or closing device which is diagrammatically shown herein, functions to pick up the old balance from the magnetic spots or perforations or from the characters on the control medium, which has been placed on the During this preliminary or auxiliary cycle the auxiliary cam line operates a portion of the machine release shaft which is associated with the amount keys only, to release any amount keys that might have been depressed accidentally. The auxiliary cam line operates a shaft line to pull in or depress the keys which have been selected under control of said magnetic spots or perforations or characters on the control medium.

The auxiliary section of the machine release shaft, the auxiliary clutch and the auxiliary motor switch are then restored, after which the Operating mechanism As above mentioned, the machine is particularly adapted to be driven by an electric motor, which is not shown in full in this application, but there is shown a worm 26 (Fig. 8), driven by the motor, which worm 2i! drives a worm gear 2! secured to a clutch driving shell 22, which will be known herein as the main driving clutch. This worm gear 25 is also secured to a clutch driving shell 23, which will be known herein as the auxiliary clutch.

Both of these clutch driving shells 22 and 23 are substantially like that shown in the above mentioned Shipley Patent No. 1,519,796, and also in the United States Patent No. 2,069,249, granted to Howard B. Scott on November 10, 1936.

Cooperating with the inner surface of the shell 22 is a clutch ring 2%, which also cooperates with a roller 25 floating between two studs (not shown) carried by a clutch roll disc This roller 25 cooperates with the inner surface of the shell 22 and the periphery of the ring 2 3. The ring 24 surrounds an eccentrically mounted driven member 2'. fastened to a gear Eli and mounted on the sleeve 29 (Fig. 10) of said gear. The clutch roll disc 26 is mounted on the hub of a stop cam 39 rigidly secured to the member 2? and the gear Mounted on the hub of the gear 28 is a switch cam 3| having secured thereto a stop block 32. Surrounding the hub of the switch cam BI is a torsion spring 33 having one end wrapped around the lower end of the block 32 and the other end wrapped around a stud 3 carried by the stop cam 30.

A shoulder 35 of the clutch roll disc 2%, a shoulder 35 of the stop cam 35 and the upper edge of the block 32 normally engage the lower end of a clutch release lever 38 mounted on a stud 39 on the machine frame AB. This lever maintains the clutch members 26, 3f 3! and 32 in their normal inactive positions,

An arm A! of the clutch release lever 38 (Figs. 8 and 10) carries a roller which normally rests upon the curved edge 43 of a lever 32 fast on a shaft 5, which extends across all of the amount key banks in the machine and has hearings in the frame 6!} and an arm (not shown). When the lever 44 is rocked counter-clockwise (Fig. 10) to release the machine, in a manner to be hereinafter described, the lever 33 is rocked counter-- clockwise and is thereby disengaged from the shoulders 35 and 36 and also from the block by a spring 4?. Counter-clockwise mov ment of the lever 38 is limited by a stud 18, carried on the frame Upon operation of the lever in the manner fully illustrated and described in the above mentioned Shipley Patent 1. 9,796, the Worm as drives the gear 2! and shell and the spring 3-3 rocks the clutch roll Zfi to force the roller 25 into a position to we ge the r ng 2 against the inner surface of the shell 22 and presses the ring tightly against one side of the driven member 21 so that the shell 22, the roller 25, and the ring 24 operate as a single unit to drive the member 2-1 and the gear 28, which 'is secured thereto, as is fully illustrated and described in the above mentioned Scott Patent No. 2,060,249.

The movement of the switch cam 3! by the spring 33 rocks lever 59 (Figs. 10 and 11) whereupon the upper end of said lever engages a roller carried by a lever 52 pivoted to the motor frame, and moves the free or right end of said lever downwardly as viewed in Fig. 11, to cause an insulated portion 53 of said lever to move a pair of contact springs 54 into engagement with contact points 55, thereby closing the circuit through the motor to drive the worm 20 as above mentioned.

The gear 28 and its sleeve 29 are journaled on a stud 62 carried by the frame 40. This gear 28 meshes with an intermediate gear 64, which in turn meshes with a gear 65 secured to a main shaft 66 of the machine. Through this gearing the cam shaft 65 is rotated once during each main operation or cycle of the machine.

For the purpose of restoring th lever 38 to locking position near the end of the operation of the machine, a link 61 is pivoted at 68 to the arm 5! of the lever 38. The gear 65 carries a stud (59, which near the end of the operation of the machine engages a curved surface H3 of the link 61 and raises the latter, thereby moving the arm 4! and consequently the lever 38 clockwise to their normal positions, and into the path of the shoulders 35, 36, and block 32, to stop and hold the clutch members 26, 30 and 3| in their normal positions.

As will be hereinafter described, the lever 54 is rocked clockwise to normal position just before the stud 69 passes out of engagement with the bottom surfaces m of the link 81 in order to retain the leve 38 in its normal position.

The operation of the clutch release lever 38 has been above described as taking place during a normal adding operation of the machine.

However, in connection with the present invention, wherein, as above stated, there is a preliminary or auxiliary cycle of the machine prior to the main cycle of the machine, this lever 38 is positively controlled by means operable during the preliminary or auxiliary cycle to prevent the release of this lever at any time during the preliminary or auxiliary cycle. This clutch release lever 35, however, is also controlled so that it will be released automatically at the end of the preliminary cycle, whereupon the machine will automatically be permitted to go through its main or regular cycle of operation, whereby the differential mechanism will be set up under control of the amount keys which have been automatically selected and automatically depressed during said preliminary or auxiliary cycle. Mechanism for so controlling this main clutch release lever 38 will be described in connection with th description of the auxiliary cycle mechanism.

Preliminary or auxiliary cycle As above stated, the machine is adapted to perform a preliminary cycle, which involves certain novel mechanism associated with the regular mechanism, to control the clutch releasecycle and mechanism to perform-those functions, which will be set out in detail in connection with the description of this auxiliary cycle.

When the machine is operated and used to compute records from a previous balance, which balance may be in the form of magnetic spots, perforations, or printed or other characters on a record medium, from which, through electrical means, the amount keys are automatically selected, such type of operation is initiated by the depression of either a balance pick-up key 1! (Fig. '7) or an overdraft pickup key '12. These keys are mounted in the usual key frame 13, which is supported on rods Hi and 75, in turn supported by the machine frames 36 and d6.

The key H and the key '72 each has a pin l6 and T! respectively, which cooperates with an angular surface 18 and 19 respectively of a slide 36] mounted on pins 8] carried by the key frame i3. This slide 86 has a projecting finger 82 adapted to cooperate with a switch blade 83 to close the contacts of the switch 8% whenever the slide is moved to the right by the depression of either the balance pickup key ll or the overdraft pickup key 12. As can be seen from Fig. 7, whenever either of the keys H or i2 is depressed, its pin 56 or 17, through the angular surface '28 or "J9 will move the slide 83 to the right, whereupon the finger 82 contacts the switch blade 83 and moves the same to the right to close the contacts of the switch 84.

The circuits closed by this switch will be hereinafter described at the proper time.

The auxiliary clutch, including the shell 23 (Fig. 8') is'comprised of a clutch ring 35, a roller 36, a clutch roll disc 81a driven member 88,:

a stop cam 89, a switch cam' 90, a stop block 9!, and a torsion spring 92, connected to astud 93 on the stop cam 89 and to the lower edge of the stop block 9|. A shoulder 94 of the clutch roll disc 87, a shoulder 95 of the stop cam 89, and the upper edge of the stop block 9!, normally engage the lower end of an auxiliary clutch release lever 98 to maintain the clutch members 3'5, 89, 90 and 9!, in their normal positions. The above described clutch members are substantially identical with the'main clutch members which have been previously described, and when released function in substantially the same way as the clutch members of the main clutch.

The auxiliary clutch lever 98 (Figs. 6 and 8) is pivoted on a stud 99 carried by an auxiliary side frame I00. An arm IBI, integral with the clutch release lever 98, carries a stud i532 cooperating with the surface H33 of a clutch release control lever [04, secured to an auxiliary release shaft H15. This shaft M5 is in axial alinement with the release shaft 45, as shown in Fig. 8, and is supported by the auxiliary frame 25!] and the hub l 06, rigid with the main release lever le.

When the release shaft I05 is rocked counterclockwise, as will be hereinafter described, the lever m4 is rocked in the'same direction, and the surface H33 passes from beneath the stud H32, whereupon a spring H31 connected to the auxiliary clutch release lever fil rocks this lever 98 counter-clockwise untilit is stopped by a limit stud I 88 carried by the auxiliary frame 5863. Upon this counter-clockwise movement of the clutch release lever 98 the worm 2E drives the worm gear 2! and she l 23, and the auxiliary clutch members are set in position by the spring 92 to cause the shell 23, the roller and ring 85 to operate as a single unit to operate the driven member 88 to drive a gear H39 in exactly 9 the same manner as the regular driven member 27 drives the gear 28 in connection with the regular clutch.

The movement of the switch cam 953 rocks a lever Hi3 (Fig. 11) like the lever 56, which lever HG, through its engagement with a stud Hi on a lever l [2, rocks said lever to cause an insulated bar US, carried thereby, to move the switch contact springs d into engagement with the contact points 555, thus closing the main motor switch to drive the worm 253 in exactly the same manner as was described in connection with the movement of the lever 50 when the clutch release lever 38 is released.

The gear ltd meshes with an intermediate gear i2 3, which in turn drives the gear 125 secured to an auxiliary drive shaft E26 supported by the auxiliary side frame I69 and a sub-frame I23. Near the end of the preliminary cycle, the auxiliary clutch lever 98 is restored to its normal position by means of a link i2? pivoted at I23 to the arm iii! of the clutch release lever 88. The stud I29, carried by the gear Hit engages a surface ltii of the link I27 and raises the link, and consequently rocks the lever 98 clockwise to its normal position just before the end of the preliminary or auxiliary cycle.

The machine release shaft in the present case is divided into three sections namely, shaft 55 which extends from the left side frame as of the machine to a point near the right side frame 56, as shown in Fig. 8, an auxiliary shaft E85, which has been previously described, and a third shaft Mi (Figs. 8 and 9). The shaft extends across all of the amount banks in the machine, and the shaft It! of the machine release shaft extends only across the control banks of the machine, which control banks are, as is well known in the art, located to the right of the amount bank. There are usually three control banks in the machine, a portion of one of which is shown in Fig. 7.

There is a coupling between the shaft MI and the shaft 45, and another coupling between the shaft 55 and shaft H35, which couplings will be hereinafter described, and which are for the purpose of permitting the shafts G5 and M5 to be reeased upon the depression of the Balance Pickup key if or the Overdraft Pickup key 72, which are shown in Fig. 7.

The Baance Pickup key M and the Overdraft Pickup key #2 cooperate directly with the release shaft HM, and when either of these keys is depressed this shaft l ll is permitted to move in a clockwise direction as viewed in Fig. 7, or counter-clockwise as viewed in Fig. 9.

The release mechanism and couplings for the release shaft will now be described. Cooperating with the keys H and 72 (Fig. 7) is a control bar I42 adapted to be moved toward the left by the depression of either one of these two keys.

This control bar I42 is mounted at its lower end by means not shown, which is pivoted on the lower stud 8 l, and at its upper end on an arm M3, pivoted on the upper stud 8|. The arm M3 carries a pin M4 cooperating with an arm I45 of a yoke Hi5 pivoted on a rod i i! supported by the machine frame. Integral with the yoke I46 and arm M5 is an arm E48 normally held in front of an arm Hi9 secured to the machine release shaft MI. A spring 55E connected to a stud in the arm I65 holds the latter in its normal position. A spring [M is tensioned between a stud on the arm I45 and the usual non-repeat pawl I52.

From the above description of the parts it can be seen that when either the Balance Pickup key N or the Overdraft Pickup key i2 is depressed the movement of the bar 1 32 to the left rocks the arm Hi3 clockwise, whereupon the pin [44, through the arm M5 and yoke f it, rocks the arm I48 counter-clockwise against the tension of the spring 50 until the arm M8 is moved above the arm 149. When this occurs, the shaft l il is immediately moved in a clockwise direction, as viewed in Fig. 7, and counter-clockwise as viewed in Fig. 9 by the following mechanism. Secured to the shaft MM is an arm I56 carrying a stud I57, which supports a pair of members i523 (only one of which is shown), and the lower ends of which are surrounded by a coil compression spring IE9 compressed between shoulders on the members I58 and the end of a slot 50 in a link lfii which also surrounds the stud 551. This last described mechanism is old and well known in the art, and fully illustrated and described in the above mentioned Shipley Patent 1,619,796.

From the above description it will be clear that when the arm M3 is moved upwardly, thus releasing the arm MQ, the spring 851*}, being under compression, will exert its power through the members 258 to rock the arm I56, and consequently the shaft Mi, in a counter-clockwise direction as viewed in Fig. 9. This is clockwise as viewed in Fig. 7.

When this movement of the shaft Ml occurs, an arm I62 (Figs. 8 and 9), secured thereto, is moved in a counter-clockwise direction, whereupon a pin carried by an arm iris, secured to the shaft :5, is released to permit the arm hi-i and shaft 55 to move in a counter-clockwise direction as viewed in Fig. 10, under the influence of a spring 565 secured to the previously de scribed lever id.

Therefore, upon release of the shaft Mi, through the coupling members E82, N33, and i5 1, the shaft 55 is permitted to move in a counterclockwise direction, as viewed in Fig. 10, under the influence of the spring 455.

It will be recalled from the previous descri tion that the depression of either the Balance Pickup key 7! or the Overdraft Pickup key i2 closes the switch (Fig. 7). The closing of this switch closes a circuit to be later described, to energize a magnet ill (Fig. 6) having secured to its core member an arm 5'52, to which is pivoted at H8 a link lid, carrying a pin H5, which projects into a slot N8 of an arm ll? secured to the shaft 585, as shown in Figs. 6 and lo. When the pin IE5 is moved to the left under the influence of the energized iagnet or solenoid Hi, said pin I is moved into the path of a surface [i8 of an arm Hi9, which is secured to the hub 196 of the lever 55, which it will be remembered is secured to the release shaft 5. The link is forked at its upper end and is normally held against the shaft by a sprin i From the above description it will be clear that when the lever id is rocked counter-clockwise, as viewed in Fig. 19 by its spring Hi5, and after the pin H5 has been moved into the path of the surface 178 of the arm H9, this arm if?) by its engagement with the pin 5 Eli in a to will. move the arm counter-clockwise direction. Thus, the shaft I and the lever ace secured thereto are rocked counter-clockwise.

It will also be recalled that when the arm 2534 is moved in a counter-clockwise direction, as just mentioned, its surface 63 moves from beneath the stud I82 of the auxiliar clutch release lever 98, thus releasing the auxiliary clutch mechanism so that it can be driven by the clutch shell 23, shown in Fig. 8, to drive the auxiliary mechanism shown in Fig. 6 through one cycle prior to the regular cycle of operation of the machine.

It is necessary, at this time, to prevent the release of the main clutch release lever 33 (Fig. 10) when the clutch release lever 93 is released. This is accomplished by the following means:

The arm Iii, which has just been described, is provided with a finger I82, which cooperates with a stud I83 carried by the arm LII of the main clutch release lever 38. As the arm Ill is moved counter-clockwise (Figs. 6 and 10) the finger I82 is moved directly beneath the stud I83 prior to the time that the surface 43 of the lever id is moved from beneath the stud 52 of the arm i therefore, even though the lever M and the shaft 45 are moved into their released positions by the spring I65, the main clutch mechanism cannot be released because at this time the main clutch release lever 38 is held in its normal position by the finger I32 having been moved directly beneath the stud I83 on said lever 38.

From the description of the above mechanism it will be clear that upon the depression of either the Balance Pickup key 7| or the Overdraft Pickup key 72, the three sections of the release shaft, namely, MI, 45 and I65 (Figs. 6, 8 and 10) are released and caused to move under the infiuence of their springs I59, and I 65 through the coupling members I62, I56 and I79, and pin I75, to effect a release of the preliminary or auxiliary mechanism so that this mechanism may be driven through one cycle of operation just prior to the main cycle of operation. It will also be clear that while the shaft 45 is released the main clutch shell 22 cannot drive the main clutch mechanism and the gear 28 because the main clutch release lever 38 is locked in its normal position by the finger I82 and stud I83 during such auxiliary cycle.

Near the end of the preliminary cycle the shaft I95 is restored to its normal position, and when this occurs the finger I82 is moved from beneath the stud I83, whereupon the spring cl rocks the main clutch release lever 38 counterclockwise, as viewed in Fig. 10 to release the main portion of the clutch so that the clutch shell 22 can drive the gear as in the manner previously described, to drive the main cam shaft 96 of the machine.

The means for restoring the shaft I95 to its normal position will now be described. The intermediate gear I24 (Fig. 6) meshes with a gear I84 which is mounted on a short shaft I85, supported by the frames I99 and I23. Secured to the side of this gear I8 3 isv a disc I95, having a cam race I81, which cooperates with a fiat sided stud I88 carried by an arm I89 which is secured to the shaft I85. Ihe cam slot #8? has a wide section I99 so that when the shaft I95 is released and rocked counter-clockwise in the manner previousl described, the flat stud I88 will be moved to the right into this wide section E93 of the slot IS'I'. As the gear I3 and the disc I 86 are given one complete rotation in a counter-clockwise direction during the auxiliary or preliminary cycle, near the end of this cycle the cam race I81, through its engagement with the pin 83, rocks the arm I89 clockwise back to the position shown in Fig. 6, whereupon the shaft I95 and the mechanism thereon is moved likewise.

During this clockwise restoring movement of the shaft IE5 the arm II! is moved likewise, and during the first part of this restoring movement the ringer I82 is released from beneath the stud I83 so that the spring 41 (Fig. 10) can rock the main clutch release lever 38 counter-clockwise to release the main clutch so that it will be driven by the main clutch shell 22 to drive the gear 28 to operate the main cam shaft 88 or" the machine.

Before the arm I06 is restored clockwise to its normal position, the stud I29 (Fig. 6) will have moved the clutch release lever 98 clockwise to its normal position through the engagement of the stud with the bottom of the link I21 so that as the lever Ice reaches its normal position it will pass beneath the auxiliary clutch release lever stud I92, thus locking the auxiliary clutch mechanism in its home position.

Should any of the amount keys have been depressed prior to the beginning of the auxiliary cycle of the machine, there is provided a device operated during the auxiliary or preliminary cycle for automatically releasing any amount keys in the machine which might have been accidentally depressed. This mechanism is as follows:

Secured to the shaft I isa plate camv I9I (Fig. 6) which cooperates with a roller I92 on a lever I93 pivoted on a stud I94 carried by the frame use. The upper portion of this lever I93 has an offset arm I95 (Figs. 6 and 8). The stud I92 is normally held against the plate cam I 9I by a spring I 95. This offset arm I95 cooperates with a long stud I9? (Figs. 8 and 10) carried by the release lever Mi. As the gear I8 3 is rotated counter-clockwise, and near the middle of the cycle of operation, the cam plate I9I rocks the lever I93 counter-clockwise, whereupon the offset arm I95, by its engagement with the stud I91, rocks the lever 44 in a clockwise direction to automatically release any amount keys which may have been accidentally depressed prior to the beginning of the auxiliary cycle. The means which actually releases restores the keys will be hereinafter described.

To insure that the gear 84 and all of the parts connected therewith are brought to their normal positions at the end of the preliminary cycle, the plate or disc I85 is notched as at I98 to cooperate with a stud I99 on an arm 290, which is pivoted on the stud I94. The stud I99 is held always in contact with the periphery of the disc I96 by a strong spring 2M so that should momentum cause the gear I89 and disc I86 to be moved slightly past normal position in a counterclockwise direction at the end of the preliminary cycle, the spring ii -I, through the pin I99 will restore the disc I65 in a clockwise direction to its normal position and this will also insure that the gear I24 and all the gears meshing therewith are in their normal positions at the end of this preliminary cycle.

The intermediate gear I24 meshes with a gear 2532 (Figs. 6 and 8) which is mounted on a short shaft 253, supported by the frames I23 and Hit. Secured to the gear 252 is a plate cam 26%, which cooperates with, and controls a normally closed electric switch 205, the purpose of which will be hereinafter described.

The previously described gear 525 (Fig. (3) has cut in the side thereof a cam race 2st, into which projects a roller ZEBI carried by a lever 29S pivoted on a stud 299 supported by the frame 595. Pivoted to this lever 2% is a link 299 which in turn is pivoted to an arm 2H3 secured to a 13 shaft 2Il supported by the frame I60, and brackets 2l2, which in turn are carried by a bar 2 13 supported by the frames 4!] and 45, as viewed in Fig. 8.

The configuration of the cam race 286 is such that during the preliminary or auxiliary cycle the shaft 2H is rocked first counter-clockwise and then clockwise to normal position, as viewed in Fig. 6. As viewed in Fig. 1, this direction is first clockwise and then counter-clockwise. This shaft 2H also has secured thereto an arm 2H1 connected by a link 2l5 to a key operating slide 2 It, the purpose of which will be hereinafter described in connection with the key bank mechanism.

Regular cycle operation When it is desired to perform a regular cycle of operation for the purpose of adding an amount into the totalizers or for subtracting an amount from the crossfooter the operator manually selects the amount keys 2ll representing the amount desired and manually depresses or operates such keys. He then depresses, for example, a motorized or machine release key 2l9 (Fig. '7) having a pin 22% which cooperates with the control bar M2. This pin 22% upon depression of the key 2l9 moves the bar I42 to the left to rock the arm I48 counter-clockwise away from the front of the arm I42 secured to the shaft [45 thus releasing this shaft l4l to the action of the spring l59 which rocks the shaft lit, and coupling arm I62 to permit the spring I65 (Fig. 10) to rock the shaft 55 and release control lever 24' counterclockwise to release the clutch release lever 38, whereupon the regular clutch shell 22 is permitted to operate the gear 28 to drive the machine through a regular cycle of operation.

Since the ke 255 does not cooperate with the slide 88 (Fig. '7) the switch 84 is not closed and consequently the magnet Ill is not operated and therefore the auxiliary release shaft I05 is not released thus preventing the operation of an auxiliary cycle when the amount keys 2?! are manuall selected and manually operated followed by a depression or operation of the machine release key 2l9.

Machine release controlling circuits As previously described, this invention involves the automatic selection and operation of amount keys which automatic selection and operation are performed in what has been termed herein, a preliminary or auxiliary cycle of the machine which occurs immediately preceding the regular or main cycle of the machine. It has also been described how the main cycle of operation takes place automatically immediately following the preliminary or auxiliary cycle.

To initiate the auxiliary cycle requires the depression of either the balance pickup key ll or the overdraft pickup key '52 which are shown in Fig. 7. The depression of either of these keys, as previously described, closes the switch 84 to energize the magnet l'll (Fig. 6) to move the coupling pin H5 into coupling position so that the auxiliary shaft H15 may be released through the action of the machine release shaft 45 and the machine release shaft MI in the manner previously described.

The circuits to control the energization of the magnet ill are illustrated in Fig. 3 in a diagrammatic form and will now be described.

In connection with these circuits, there is secured to the gear 262, which is operated only during the preliminary cycle, a cam 22l which cooperates with a switch 222 to normall hold that switch closed.

The closing of the switch 84 by either the balance pickup key ll or the overdraft pickup key l2 establishes a circuit from a positive potential of v. D. 0., through line 223, through the switch 85, line 22%, switch blade 225, line 226, line 227, to a relay 228. From the relay 228 through line 229 to ground 239 thus completing the circuit to energize and operate the relay 228.

The circuit just completed energizes the relay 228 which attracts the three switch blades 23l, 232 and 233 to close the following circuits.

The magnet l'll is in a separate circuit of volts, A. C. 60 cycles and when the switch blade 232 is operated by the energization of the relay 228 a circuit is completed from line 234' of the 115 volt circuit through the switch blade 232, through line 235 to the magnet ill and thence to line 236 to the opposite side of the 115 volt circuit thus energizing the magnet ill to couple the auxiliary releas shaft [25 to the release shaft 45 to effect the release of the auxiliary clutch release lever 98 in the manner previously described.

The energization of the relay 228 through the movement of the switch blade 233 closes a circuit from the positive line 223, through line 2 32, switch blade 233, line 24!, relay 242, line 223 to the ground 238 thus energizing relay 252. The energization of relay 222 operates the switch blade 225 and a switch blade 24 3'. The operation of the relay 242 closes a holding circuit for itself from line 223, switch 84, line 224, switch blade 224, line 245 to point 246, through the relay 222, and line 243 to ground 238. The operation of this relay 242 also by its operation of the switch blade 225, opens the key operated circuit by breaking the contact between the switch blade and line 226.

The relay 228 is now held in operated condition by a circuit from the line 223 through line 25l, switch blade 23l, line 252, to switch 222 which is still held closed by the cam 22l, and from switch 222, through line 227, relay 222, line 229 to the ground 239.

At an approximate degrees time in the auxiliary cycle, the cam 221 releases the switch 222 permitting it to open and thus breaking the circuit through the relay 228 whereupon the switch blades 23l, 232 and 233 are released, thus breaking the circuit at the switch blade 232 for the magnet Ill and breaking the main circuit to the relay 242 at switch blade 233. However, the relay 242 is still held by its holding circuit from the positive potential through line 223, switch 84, line 224, switch blade 242, line 245, to point 246 through the relay 242, line 243 to the ground 230.

Due to the fact that the switch 222 is closed just before the end of the preliminary cycle it is necessary to hold this relay 242 active at this time in order to keep the circuit for the relay 228 open at this time at the point between the switch blade 225 and line 226 because the switch 84 remains closed at the end of the preliminary cycle and also during the regular cycle which follows the preliminary cycle, until the depressed balance pickup key ll or the depressed overdraft pickup key '12 is restored near the end of the regular cycle.

access? 15 Amount keys As has been previously stated, the amount keys in the present invention are adapted to be automatically selected and the automatically selected keys automatically depressed, the automatic selection being under the control of magnetic spots or perforations, or other controlling characters on a control medium such as a card or tape, or any other type of medium which is desired and convenient to use in the machine. It has also been previously stated that these same keys may be operated manually, that is, they may be manually selected and manually depressed.

In the present application there is shown only one bank of amount keys, but it is to be clearly understood that as many banks, like that shown, may be used as is necessary, depending upon the capacity of the keyboard which is desired in the particular business in which the machine is being used.

The selected and operated or depressed keys control differential mechanism of the usual type shown and described in the above mentioned patents, which difierential mechanism in turn controls the accumulation upon the totalizers and also controls printing mechanism such as shown in the above mentioned patents.

In Figure 1 there is shown one bank of amount keys and its associated differential mechanism. This bank of keys is what is known as a flexible key bank as previously stated. In each of the amount banks of keys there are nine amount keys 2' (Figs. 1 and 2) which are sup.- ported in the usual type of key frame 272 mounted on the rods 14 and 15. Each key 275 carries a pin 213, which projects from both sides of the key stem, to cooperate with a controlling bar 274 and a locking detent 215. The controlling bar 214 is pivoted at its upper end to an arm 216 pivoted on a stud 2?! supported by the key frame 212. The lower end of the controlling bar 214 is pivoted on an arm 278 supported on a stud 2T9 carried by the key frame 212. This arm 218 cooperates with a pin 230 in an arm 28! secured to a short shaft 232, to which is also secured the usual zero stop pawl 283. A spring 28 5 normally holds the pin 2% against the arm 2T8. Depression of any one of the amount keys moves the controlling bar 214 downwardly, whereupon the arm'ZlB by its contact with the pin 286 rocks the zero stop pawl 283 counter-clockwise from its eifective position shown in Fig. 1 to an ineffective position, so that the differential mechanism to be hereinafter described can be set under the control of the depressed key.

Also when one of the keys is depressed, its stud 213 moves the locking detent 215 downwardly until the pin is beneath a hook 2-85 on the detent, whereupon a spring 288 rocks the detent back to its normal position to retain the key in its depressed position. When a key 2H is manually depressed, the movement of the detent by the pin 213 releases any key 21! that might have been depressed in the same key bank. This type of key bank is known in the art as a flexible key bank. This locking detent is supported at its upper end by an arm 28'! pivoted on the stud 217, and at its lower end on an arm 288 pivoted on the stud 215). The usual springs 289, one associated with each of the key pins 213, normally retain the keys 2il in their outer or undepressed positions.

Each of these keys 2' is normally longer than those shown in the above mentioned patents,

and each of said keys 211 has secured thereto a coupling in carrier Bel (Figs. 1, Z and a), in which is slidably mounted a lightweight coupling pin 392 having an annular groove 3B3 engaged'by a lip 3% of an armature 305 of an electromagnet 30 3 mounted in a bracket 30! secured to the top of the key frame 272.

The armature 385 is freely pivoted in a slot 368 in the side 2309 of the electromagnetic bracket 3M. A compression spring tie is extended between a stud ill on the armature 395 and a finger 312 on the bracket Sill. This spring 3!?) normally holds the armature M55 in the position shown in Fig. 4, whereupon the hollow pin 3532 is held in a position wherein its inner end is inside the side face of the key 21 i.

The previously described key operating slide 2H6 (Figs. 1, 2 and 4) lies adjacent the sides of the keys 2' and is mounted to slide on studs 3E3 and 3M carried by brackets 315 and 315, respectively, which brackets are secured to the top of the key frame 212. The slide 2H5 has slots 3|? and 3H; which surround the pins 3G3 and 3M. This slide 2V3 is provided adjacent each of the pins 382 with a camming notch 319, the purpose of which will be hereinafter described.

As shown in Fig. 1, there is an electromagnet 3G5 and associated mechanism cooperating with each one of the keys 2'. These electromagnets are adapted to be controlled by magnetic spots or perforations, or other printed or written con trol characters on a control medium 325), which may be a card or slip or tape. This control medium 329 is shown diagrammatically in Fig. 5 in connection with the wiring diagram for this invention.

When any one of the electromagnets 39.6 is energized by means to be hereinafter described, it attracts its armature 385, which is rocked counter-clockwise as viewed in Fig. 4, whereupon the lip 3G4 moves the pin 392 inwardly with relation to the carrier 3%! and projects the inner end of the pin 352 beyond the key 2?! and into its associated camming notch 3 l 9 of the operating slide 256.

This energization of the magnet 396 occurs during the first part of the preliminary cycle which has been above described, after which the shaft 2!! (Fig. 1) is rocked in a clockwise direction by means of the cam race 2% (Fig. 6) in the manner which has been previously described. This movement of the shaft 2| I through the arm 2M and link 2H5, moves the key operating slide 255 to the right, as viewed in Fig. 1, whereupon one of camming' notches 3K3 engages the proiected end of the associated pin 3%2, which has been moved inwardly by the energized magnet thus depressing its associated amount key 2H to move its lower end into the path of a difierential mechanism to be hereinafter described, to control the extent of movement of that differential mechanism.

When a key 2?! is so depressed by the automatically operated key operating slide 2m. its associated pin 273 operates the locking detent 2'55 in the manner previously described, where" upon the automatically depressed amount key 2?; is retained in its depressed position at the end of the preliminary cycle "and during the regular cycle of the machine which follows, in order that the difierential mechanism shown in Fig. 1 and to be hereinafter briefly described, will be controlled by the value of the key which has ataassvi been automatically selected and automatically depressed. v

Near the end of the preliminary cycle the electromagnet 3&6 is deenergized by having the circuit thereto broken, whereupon the spring 318 restores the armature 385 to its normal position and through the lip 3E4 simultaneously draws the pin 3622 out of cooperation with the camming notch 3MB of the key-operating slide 25-53. After this occurs the cam race 256 (Fig. 6) rocks the shaft 21! counter-clockwise (Fig. l) to its normal position, which restores the key operating slide 2; to its normal position shown in Fig. 1. The slide H6 is held in sliding position on its studs 3l3 and 3h; by a cover plate 32L which is secured to the top of the key frame 272 and also secured to the ends of the studs 313 and 3M.

Circuit for key selecting magnets -The circuit for controlling the energization of the magnets 39% will now be described. Secured to the bracket 3 I6 (Fig. 1) is a ten-wire plug 322, nine of the wires which run between insulating sheets 323 and 324 (Fig. 2). One or these wires goes to each one of the electromagnets 336 and the tenth wire is fastened to the frame as a ground Wire. The ten wires from the ten wire plug 322 are adapted to be put into a ten-wire socket 325 shown diagrammatically in Fig. 5, the wires from which lead to a selective circuit closing device 326, also shown diagrammatically in this Fig. 5.

' Let it be assumed that there is a magnetic spot or a perforation or a printed or written control character in the 8 position of the control medium 32a, shown diagrammatically in Fig. 5. In this case the electromagnet 333 associated with the 8 key 27! will be energized and the circuit for the energization of this magnet is as follows:

From the ground 33!, through battery 332, switch 2&5, line 333, line 334, into the selective circuit-closing device 323, through the perforation or control character on the control medium 329, indicated at the point of the arrow 335, to line 336. From the line 336 the circuit continue to the socket 325, to the plug 322, through line 331 to the electromagnet 3% associated with the 8 key 21!, from this electromagnet 39% to line 333 to line 339, through the plug 322, socket 325, to ground 34%). Th .magnets' 33% are all normally partially energized by means of a holding circuit, later described, and thus the above circuit causes the selected magnets to be fully energized. Therefore the magnet 3% associated with the 8 key, attracts its armature 3 35 to move its associated pin 332 into the camming notch 3l9 of the keyoperating bar 2| 3.

When the magnetic spots on the control me dium 323 are used to control the selecting magnets 336, such spots cause electrical impulses in the circuit by means of appropriate amplifiers to perform a function similar to that performed by perforations, that is, to close the circuit. Said impulses are sufficient to cause full energization'of the selected magnets whereupon such fully energized magnets attract their respective armatures to actuate or move their associated pins 3B2 into their related camming notches 3l9 of the keyo'perating bar 216.

Since it is contemplated controlling the above described circuit by a scanning movement of the control medium 320, there is a normally closed holding circuit for the magnetBOB, which is as From the ground 33L battery 332, switch 205, line 333 to line 3el, resistor 342, line 343, to the line 33c, and thence through the socket 325, plug 322, lin 331', magnet 395, line 338, line 339, and back to the ground 34%].

This holding circuit, through the resistor 342, is maintained until near the end of the preliminary cycle of operation and is opened when the low portion tic oi the cam 24% comes adjacent the switch 2e25, thus perrmtting this switch to open and break the holding CilCellt for the magnet 306.

This low position 3% covers sufficient time in the cycle of its operation to permit the thus deenergized magnet Sue to release the armature 305 whereupon the spring 3h) restores tile pin 302 in the manner above described. However, the key lit at this time is in its depressed position, but' the armature we" and lip 3m are long enough, as viewed in big. 2, so that the lip 3M3 still engages th pin 332 while the key 2 is in its depressedposition.

l rom the above description it will be clear that whenever there is a magnetic spot or a perforation or a printed or written control character on the control medium 32o opposite any one of the wires in the selective circuit controlling devicethat the electromagnet Bee will move the pin 302 and thus automatically select an amount key, depending upon the relative value position of the 1 magnetic spot or perforation, or printed or written control character on the control medium 32d. Such automatic selection of the keys 2H occurs during the prellinlnary cycle, and during this same preliminary cycle of the machine said automatically selected key is automatically de-' pressed by operation or" the key-operating slide in the manner previously described. Thus, the differential mechanism which will be hereinafter briefly described is controlled as to its extent of movement by the automatically selected andautomatically operated key.

Differential mechanism The diiierential mechanism shown in this case is that shown in connection with one single amount bank, and is substantially identical with" the amount differential mechanisms shown in many of the above mentioned patents, and therefore only a brief description thereof will be given herein. 7

Depression of any one of the amount keys 2H, either automatically or manually, rocks the Zero stop pawl 233 associated with that particular de nomination counterclockwise out of the path of a reset spider tiiii free on a hub of an amount dif-. ierential actuator rotatably supported on a bushingtfit extending between two hangers or supportplates (only one here shown) said. plates being in turn supported by rods 355 and S55 extending between the main frames it and 43. There is a pair of supporting plates 35 for each amount differential and a tie rod 351 extends through the holes in the center of the bushings 353 to secure all of the amount differentials in a compact unit.

A notch in the forward end of the spider 35l engages a stud 353 in a forward extension of a bell crank 35-3 pivoted on an extension of the ac-'. tuator Carried by the vertical arm of the bell crank 35% is a stun on which is pivoted an arm 36L The arm 3 s also pivoted to the upper end of a latch 3G2 pivotally mounted on the actuator 352. The latch 332 has a foot 363 normally held in contact with the periphery of a driv- 7 5 ing segment 3&4 just above a shoulder 365 thereon is by means. of a. spring 356. The. driving; segment 334; is rotatably supported. on the hub. of the a tnator 35.2.. Alink 3.61 pivotally connects. the. drivsegment. 334 to a cam. lever 3.6.8. pivoted on a. stud 369 in the left-hand one, of the plates 354, said lever 3.3.8 carrying rollers 3'13 and 31! which coact. with the peripheries. of cams 372 and 313-, respectively, secured on the. main cam shaft 69.. Depression of anyone of the amount keys 21! moves the lower end thereof into the path, of a rounded surface 3.14 of the bell crank 35.9.

. In adding operations, or in other words, in the mainv cycle. of operation which immediately follows the,- previously described preliminary or aux! iliary cycle, the main shaft 96 and cams 312 and 31-3. make one clockwise revolution, causing the lever 3.5.8 to. rock the driving segment 364. first. clockwise. and then counter-clockwise back to. normal position. Clockwise movement of the seg- 11181311354. causes the. shoulder 365. thereon, in, co: operation with the foot 363 of the latch 3.62v to carry the. latter and: the, amount. actuator 352 clockwise in unison until the rounded surface 314 contactsthe. stem of the depressed key 2;! I. This rocks the. bell crank 359, and through the arm 3&1, thelatch 362 counter-clockwise to disengage the, foot 363 of the latch from the shoulder 365 to arrest the clockwise movement of the actuator 351 and topositionsaid actuator according to the value of the depressed amount key 2'. Disen.-. easement. of the. latch 332 moves the rounded ex ten ion of the arm. 36! into. engagementwith the corresponding. one of a series of locating notches 315 in a plate 37 3. secured between the rod 356 and an upward extension of the. left-hand supporting plate. 354..

, After he. latch 3.6.2 is disengaged from the shoulder 365, an; arcuate, surface 31.! on the seg-. ment. 36A. moves opposite the foot. 3.6.3. to retain thev atch n its set position.

When the lever 398reaches the terminus of its clockwise movement a roller 318 carried thereby coacts with an arcuate surface 319 on a beam 38,0. pivoted on a, stud 38l carried by the actuator 3 52,, and forces a conoaved surface on the upper edge of said beam 389 into contact with the hub of'th actuator 352 to move the rearward end of the, beam into a position commensurate with, the- Ydlue. of the depressed amount key.

The rearward end of the beam 339 is bifurcated to engage a stud 39| in a link 3.92, the lower end of which is pivotally connected to a segmental arm 393 which is used to set up type wheels of a column printing mechanism of the type fully illustrated and described in a patent to Charles H, Arnold No. 2,141,332 and embodies an application of the well known principle of driving mechanism disclosed in the United States patent. to Walter J. Kreider No. 1,693,279.

From the above described mechanism it is clearhow the differential actuator 352 is set under con-. trol of the depressed one of the amount keys 2'.

Each of the actuators carries three sets of gear teeth 3.94, 395 and 393 which cooperate with lines of' totalizers 391, 399 and 399, respectively, to. cause the value of the amount key depressed to be accumulated into the selected one or ones of the. totalizers on the lines 391, 398 and 399, in a manner which is well known in the art and which is also fully illustrated and described in several of the above mentioned patents.

whereupon a member 499 secured to, the shaft 45 contacts. the arm 231 upon which the locking detent 215 is mounted, and moves the locking (1 tent downwardly or toward the front to release the hook 285 fromabove the pin 213 of the depressed key, whereupon the associated key spring 289 will restore the. key to normal undeprcssed position; After this movement of the Shaft. 45 it is moved slightly clockwise back to its normal p0.-v sition, whereupon the Spring 286 restores the looking detent 215. to its normal position shown. in

Fig. 1.

As previously stated any amount keys 2?] that might have been depressed, manually, prior to an auxiliary cycle of operation, are automatically released during such auxiliary cycle of operation so. as not to. interfere in any way with the auto, matic selection and automatic depression of such amount keys during the preliminary cycle of op.-. eration. It will be recalled that the arm I95. (Figs. 6 and 8). of the lever I93 by itsengagement with the stud l9! rocks the lever 93 (Fig. 10,) in a, clockwise direction. This lever 44, being secured to the shaft 45, rocks said shaft 45 clock! wise (Fig. 10) which is. counter-clockwise as, viewed, in Fig. 1. Therefore, the member 409 is. rocked counter-clockwise during such preliminary cycle of operation. and said member 400 by its enga ement with. the arm 28'! moves the looking detent, 275 to release any hook- 285 from any pin 273 of any key 21, Iv that mighthave been de-. pressed prior to the preliminary cycle of operation. Any such released key- 21! will then be restored to its normal undepressed position by its spring 289.

The auxiliary release shaft I is then restored and the auxiliary clutch release lever 98 is restored, whereupon the main cycle clutch release lever 38 is released and the gear 28, through the V main clutch mechanism drives the main cam shaft 66 through its regular one cycle of operation. During this operation the diiferential mechanism shown in Fig. l is set under the control of the values of the depressed amount keys, whereupon such amounts are, through this differential mechanism, set up on printing mechanism through the medium of the segment 393 by means fully illustrated and described in the above mentioned Arnold and Krieder patents, and at the same time these same amounts are accumulated in the selected one or ones of the totalizers 39?, 398, or 399.

As has been previously pointed out, these same amount keys 21! may be manually operated without in any way affecting the automatic selection thereof as has been described previously. When it is desired to use the machine manually and depress the keys manually, the key release shafts MI and 45 are released but the electromagnet IN is not energized, and therefore the stud I75 (Fig. 5) remains in the position shown, and consequently the coupling, consisting of the stud I and arm H9, does not operate, and therefore the auxiliary shaft I05 is not released. In order that the arm I19 can rock counter-clockwise, as viewed in Figs. 6 and 10, upon the release of the release shaft 45, there is a clearance notch in the arm 179 which moves over the stud I15 without in any way affecting any movement of the stud H5 when the machine is manually operated, that is, when the amount keys 2' are operated by hand instead of automatically through the selection of the various electromagnets 306.

Therefore, it can be seen that the present invention provides a novel keyboard mechanism wherein the keys thereof may be operated either manually by manual selection and manual depression, or they may be automatically selected and automatically depressed, the automatic operation in no way afiecting the manual operation, and vice versa, the manual operation in no way affecting the automatic selection and operation of these keys. This of course greatly enhances the value of this type of keyboard mechanism because of the much wider range of usage to which it may be put.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form or embodiment herein disclosed, for it is susceptible of embodiment in various forms.
