14 Claims.

This invention relates to printing calculating machines and more particularly to a device to permit retention of a constant factor in the value set-up mechanism for a plurality of computations involving the constant factor.

One object of this invention is the provision in a printing machine capable of addition, subtraction, multiplication and division operations of a mechanism settable to retain a factor set-up by the keyboard in the entry devices for use in a number of distinct multiplication calculations.

Another object is to provide in a printing multiplying machine a factor set-up device in which the factor may be retained for a number of operations and wherein no resetting of such device is required for a total taking operation.

A further object is the provision in such a machine of a factor set-up mechanism and a mechanism operable by the operator to re-indeX a setup factor into a controlling position at any desired time.

A still further object of this invention is the design of a factor set-up mechanism for a printing calculating machine in which a factor may be retained by the use of a locking-in mechanism but which set-up mechanism is shiftable to an ineffective position to permit other machine operations.

Still another object is the provision of a factor set-up mechanism which may be set to retain a selected constant factor but shiftable out of effective position to permit machine operations to be performed which do not involve the set-up factor and which may be re-indexed to effective position by operation of a constant key.

Other incidental objects will be in part apparent and in part specifically pointed out in the following detailed description of a preferred embodiment of the invention.

The present invention is an improvement on the mechanism shown in the co-pending application Serial No. 170,968 filed June 29, 1950 by Oscar J. Sundstrand. For this reason only so much of the structure as is required to set out the novel features of the invention is set out herein, reference being made to the above Sundstrand application for a more complete disclosure of the machine involved.

In the drawings:

Figure 1 is a perspective showing of the constant factor set-up mechanism,

Figure 2 is a view from the right side of the pin setting and constant mechanism,

Figure 3 is a top view, partly in section, of the constant re-indexing mechanism.

General description The present invention as disclosed is embodied in an Underwood Sundstrand printing calculator similar to that described in the Sundstrand application above, wherein it is particularly useful for multiplication calculations involving a constant multiplicand. This device is, however, also useful for multiplication in an adding-subtracting machine without the automatic multiplying features of the above aplication and is not restricted to use in a machine having such automatic multiplication features.

The disclosure herein is of a part of the wellknown Underwood Sundstrand calculating machine, further disclosure being deemed unnecessary, for such machine is readily available commercially and fully disclosed in U. S. Patents including among others the following patents issued to Oscar J. Sundstrand: Patent No. 1,583,102, issued May 4, 1926, No. 1,885,489, issued Nov. 1, 1932, and No. 1,965,611, issued July 10, 1934. Such machines comprise a 10 key keyboard operable to set pins corresponding to a value in a set of stationary pins, the pin setting members and a set of read-out members being shiftable across the field of such pins to change the denominational relationship in the usual manner.

The read-out members are connected to a set of type bars cyclicallyoper-ated to read out and print the set-up values and carrying a pair of racks which are selectively engageable on the return of the type bars by a register to enter the set-up values in the register.

The register is also engageable with the racks following a non-entry cycle, on the forward stroke of the type bars to control the type bars to print the total in the register. During such a total taking operation, the read-out members must be Set to a position to the side of the field of pins to prevent any interference with the rise of the type bars from any set pins and heretofore this has resulted in resetting all set pins. It has not been possible in these prior machines to retain an amount set up on the pins during a total taking operation.

The present invention provides means wherein an amount set up in the field of pins may be re tained during a total taking operation and a constant key operable to shift the read-out members back into effective position with respect to the pins.

Entry of a constant factor Entry of a factor which is to be kept available in the pins is performed in the same manner in this machine as in the prior machines of this type with the exception that all available digital positions must be indexed. This requires that the factor be indexed in the highest denominational position by entering a number of Us following the constant or if the constant factor is to be positioned below the highest order, by first entering a number of s into the higher unused orders.

Referring to Figures 1, 2 and 3, a number of numeral keys Iii are connected to a like number of push rods I! mounted on a swinging gate i2, the rear ends of the rods I resting adjacent one vertical line of a stationary field of settable pins 13. The gate 12 is spring urged to the right, Figure 3, and is retained against the urge of its spring by the engagement of a notched arcuate plate I l with an upper end 55 of gate 1122. Upon depression of any key lll'to set through its associated push rod ii, the pin it to the rear of rod H, an escapement push rod it is also operated to thrust against plate Hi and move it rearwardly to free end I5 of gate 12. The gate 52 then moves to the right until the end of push rod it strikes against the side of the adjacent notch of plate l4 and when the operated key it is released rod it is retracted and gate i2 moved to engage the side of the next notch of plate positioning the push rods H in line with the next vertical row of pins It in readiness for entry "of the next digit.

Notched plate I4 is positioned on a stationary stud l9 at its left end and carries a lever 2d piv oted thereon at 2|. Lever 2t passes in front of end [5 of gate l2 and is bent around at its right end to engage a pin 22 on plate i to limit the movement of plate Hi to prevent any undesired escapement movement of gate l2 under impetus of a hard depression of one of the keys it. A spring 23 connected to the left end of lever 28 serves to hold both plate i l and lever 2i! in engagement with-end it of gate i2.

A stud 25, Figure 2, on the rear end of gate is engaged in a slot of a carriage 26 slidable on a shaft 21 to move carriage 26 synchronously With gate [2. A plurality of read-out rods 23 slidably carried by carriage 26 are moved thereby into position to engage the set pins it. These read-out rods are connected as in the afore mentioned patents, to the usual type bars, not shown, to control the values printed and entered into the register in accordance with the settings of pins I3. A slotted pin restoring bar 29 is slidably mounted on the right end of carriage 26 to restore any set pins It to unset position as the carriage 26 moves to the left by power at the end of any machine cycle.

The position of gate [2 at any time is indicated to the operator by movement of an indicator arm 30 movable behind slots in the machine casing. Indicator arm 35 is fixed to a slidable rack 3| connected by a pinion 32 having a fixed pivot 33 to a rack 34 fixed to end I5 of gate l2.

Locking in a constant factor 4 38 in a slot 43 of slide 39. The left end of lock is is bent down into the path of ear 3? of rack 3e and when rack 34 moves into the last denominational position of gate l2, ear 3? moves latch 38 to move ear 42 of latch 38 out of slot '53 of slide 39 and free slide 39.

Slide 39 is slidable on shaft 40 and a stud 44 and is moved by a lever 35 pivoted on a fixed stud it and provided with a slot M embracing a stud it on slide 33. In the normal rearward position of slide 3%, the set up values on pins is are destroyed by bar 29 every time gate I2 and carriage 2e are returned to their home position. When lever 35 is moved to the front of the machine, bar 29 is shifted to align the slots ie or bar 29 with pins l3 and restoration of gate :2 and carriage 25 will not restore the set pins 63. Slide 39 is provided with a slotted extension 53 which engages a pin 5t of an arm 55 pivoted at 5% on the machine frame. The rear end of arm 55 is slotted to engage, when carriage is in its rightmost position, an ear 5? fixed to the lower end of bar 29. Forward movement of slide 39 will rock arm 55 counterclockwise, Figure 2,to raise bar 29 to its upper position, a detent arm 53 pivoted on carriage 28% serving to retain bar in either set position. An ear tit on the upper end of bar 25 is positioned either above or below a lower rail of a fixed channel bar $5 at all positions of carriage 26 except the fully indexed position to prevent any undesired shift of bar 29. In summary, when lever 45 is moved to its forward position, bar is is shifted to its upper ineffective position and cannot restore the set pinslt upon return to normal position, hence the factor set up on pins i3 is retained for further use.

Slide is is provided with a second slot 69 positioned, when lever 45 is in the forward constant retaining position, adjacent ear 42 of lock 38. When swinging gate 52 and rack 36 move out of the fully indexed position lock Bil is freed to move ear 12 into slot Gil. Thus slide 39 and lever A5 are locked in either of their two positions at all times that gate l2 and rack 34 are out of the fully indexed position to prevent any shift of the lever 35, slide 39 and arm 55 without a corresponding shift of slidable bar 29 on carriage 26.

It is also desirable to prevent operation of keys it when a constant factor is set up in pins 18 to prevent change in the factor. To this end, use is made of a key lock mechanism present in the standard adding e. This key lock comprises a plate 52 gure shiftable forward- ].y to underlie the bottoms of it and prevent their depression. Plate is connected to a lever "53 pivoted on a fixed. pivot E l conneeten to a linked urged rearwardly by a spring i to hold plate 62 in an ineifective position.

Normally this plate 82 is moved to key locking position during achine cycling. The 'ma'in shaft 5? of the n1&'3 ,\.113 carries, Figure l, a roller on an. arm E8 to the shaft SE. A second arm til free on shaft ii'i is connected by a spring H to press its stud 32 against arm t3. Shortly after shaft t? starts rotating counterclockwise, sted "a2 on arm iii strikes against a shoulder i3 and moves (iii and lock plate 62 forwardly to key locking position. A shoulder "M on the rear end of arm 55 is moved in this position of arm 55 in front of a stationary guide 15, spring 55 thereupon moving arm 55 upwardly to latch the arm in its moved position. Upon return of shaft 67 to its Figure 1 position, roller 58 strikes and lowers the rear end of armtfi to release shoulder 14 from guide 75 for return of arm 65 and lock plate 52 to unlocking position.

This key locking mechanism is used to look the keyboard l when a constant factor is being retained in the pins l3. A stud l8, Figure l, on arm 55 is positioned in a slot of a lever i9 pivotecl on a fixed stud 89. Also pivoted on stud 86 and connected to lever if] by a spring iii is an arm '82, spring 81 urging arm 82 clockwise in Figures 1 and 2 against a screw 33 in lever it. The lower end of arm 32 rests in back of a stud 84 fixed in arm 65. Through this mechanism, as lever 45 is moved forwardly to retain a constant fact-or set in pins 53, lever 79 and arm 82 are rocked by arm 55 to move arm forwardly to lock keys it against operation.

Reentry of the constant factor After the constant factor has been locked as above set out and has been used for the first calculation, swinging gate 52 will generally be positioned at some denominational position other the fully indexed position and if a total taking operation has been performed, gate 52 will be in the home position. When it is desired to reenter the previously set constant factor, a constant key 99 is operated. This key 39 when operated releases the notch escapement rack it for gate 2 to permit movement of gate 52 to the fully indexed position. This movement gate 52 effects a shift of the read-out pins as under pins l3 which have remained set to permit further entries of the factor.

Ke 9% is pivoted on the forward arm of a lever ill pivoted at Q2 to the framework for the keyboard, a spring connected to key 953 and a stationary stud alt serving to maintain key till and lever Si in the normal position. An upper arm of lever Si is engaged in a hole of an arm of a horizontal lever other arm a latch pawl 85 pivotally mounted thereon at 93 and urged by a spring Q8 connected between lever 95 and latch pawl so to a counterclockwise position, Figures 1 and 3. Counterclockwise movement of latch pawl E limited by engagement of an ear 9% bent down from pawl and the arm of lever 35. Latch pawl 96 holds a slide iflil against rearward movement under the urge of a spring it! connected to a post i i-2 on slide H26 and a stationary frame part by the engagement of a shoulder on the rear end of pawl 95 with an ear Hi3 bent ofi of slide ltlil.

Constant key 95 is locked when lever 45 is in its rearward position, that is when no con stant is locked into the pins [3, by an ear I64 bent oif an upstandin portion of arm 5i; resting over the rear end of lever 9|. When lever 45 is moved forwardly to retain a set-up constant, arm 55 is rocked to move ear I84 forwardly from above the rear arm of lever 9| and thereby free key 98 for operation. A detent pawl I05 pivoted on pivot 92 for lever Si is urged upwardly by a spring I06 into engagement with ear I04 and serves to hold lever 45, slide 39 and arm 55 in either set position. Depression of key as when it is free rocks lever 9| to rock lever 95 clockwise and withdraw pawl 91 from ear H33 of slide lilo. The resulting rearward movement of slide I60 acting through a lever I01 pivoted thereon at I98 and urged clockwise to engagement of its forward arm with post 102 by a spring I69 between slide I60 and lever I01, strikes square stud 2| on escapement plate hi to move plate I4 rearwardly and free gate I2 95 which carries on its -i for movement to its rightmost fully indexed position, thus in effect re-entering the previously set constant factor.

Rearward movement of slide Hill also acts to reset the conventional hinge blank H0 to prevent a total taking operation. This hinge blank H9 is moved forwardly during a cycle in which swinging gate i2 is in its home position by a stud III on a plate H2 fixed to main shaft 6? and when blank H0 is so moved, it so controls the machine that the next cycle shall be a total taking cycle. When key is depressed, the next cycle is to be an entering cycle and hinge blank I it must be restored rearwardly which is done by an extension H3 of slide I00 engaging blank I it in the rearward movement of slide Iilil.

Slide I653 is returned to its normal latched condition during the following machine cycle. Upon release of key 98, levers 9| and are restored to their normal positions by spring 93 and pawl 96 engages ear H73 of slide its, sprin 5B yielding to allow return of lever 95. An arm H5 pivoted at H6 to a stationary frame part is tensioned by a spring H1 to hold a roller H8 on the lower end of arm H5 against the left p N3 of slide me. When slide it!) is freed from pawl 93 and moves rearwardly, it carries arm H5 with it into the path of a stud H9 on plate H2 on the main shaft 61. Durin the ensuing machine cycle, stud H9 strikes arm H5 and. restores slide Hill to normal position wherein pawl Q6 moves behind ear Hi3 on the slide Hill to relatch the slide it!!! in its home position.

It has been mentioned that lever I0! is pivotally mounted on slide I00. This is to avoid a possible source of error in operation of the machine. It will be noted that if key 50 is retained depressed or is operated during a machine cycle, slide its will be free to move rearwardly during the latter half of the cycle and consequently would free escapement plate M from swinging gate i2 after gate 12 had been restored to normal position. To prevent such an erroneous release of gate l2, lever I0! is pivoted on slide I00 and has an arm I20, Figure 3, which extends rearwardly into the path of end l5 of gate l2, Then when gate l2 overthrows past its normal home position as it does on every restoration, the end IE will strike arm [20 to rock lever I01 counterclockwise in Figure 3 and move its rearward arm from square stud 2 I. This will permit escapement plate M to reengage end 15 of swinging gate [2 and retain the gate in its home position even though slide (00 is released.
