CALCULATING-MACHINE.

Patented Sept. 4, 1917.

Application filed July 8, 1916. Serial No. 108,187.

To all whom it may concern:

Be it known that I, An'rnnr. PnN'rnoos'r, a subject of the King of England, residing at East Orange, Essex county, New Jersey,

have inventedfnew and useful Improvements in Calculating-Machines, of which the following is a specification.

The invention relates more particularly to I piece or item counting mechanisms for calculatingmachines, wherein a portion of the regular counters of such machines are utilized for counting the number of pieces, items or amounts set up on the keyboard.

It has been customary to provide means to efiect the automatic step by step rotation of one or more of the regular counters of a calculating machine, to register and accumulate thereon anamount corresponding to the numberof checks, cars, bales or other items, pieces. or articles, the amounts, weights, or values of which are accumulated on other of the regular counters reserved for such calculations.

\\ In'some cases, the carrying mechanism has machine.

Many of the devices applied to prior maohines, for efi'ecting piece counting, are driven from the main shaft of the machine, and will operate to count or accumulate a succession of ones on blank or idle strokes. This type of item counters are really stroke counters, and open the way for an inaccurate count of the items,

Otherdevices employed to count items on one or more of the regular counters of a calculating machine, which are free from the above objection,'will eii'ect a count of one on a non-print operation of themechine, thereby confusing the operator, because the tot-al number of items listed will be less than the total number registered on the. item counting section of the accumuvlator.

operated, and one object ofthe invention is to provide a novel, and accurate keyboardcontrolled means to effect the counting of items, or the like on a part of theregular accumulating mechanism of the machine.

Another object is the provision of readily accessible means to control the operation of an item counting mechanism, which means can be adjusted at will, to eilect or prevent item counting, the machine being adapted for normal operation to its full capacity when the'item counting mechanism is ineffective. I

A further object is to provide a means to eiiect item counting which becomes operative only when an amount set up on the keyboard is listed or printed.

A still further object is the provision of novel means to prevent the count of one when taking a total or sub total.

Further objects are the provision of a simple, durable, and easily controlled device of this nature, which may be readily applied to machines now in use, and comprises but few parts not liable to get out of order.

The foregoing and other objects and advantages will be more .fully pointed out hereinafter and particularly set for h in the claims.

' 032, August 15, 1905 #1,133,596, March 30, 1915, for a more complete explanation of the Wales machine, the description of which hereinafter will be made as brief as possible, consistent with a clear understanding of the present-invention.

Calculating machines of the Wales type comprise a keyboard mechanism, an accumulator section, and a printer section supported between side frames 967 and inclosed within a removable casing 1065 (a fragment only of which is shown in Figs. 1 and 2).

The keys 117 of the keyboard are arranged in denominational rows, there being generally as many counters 490 in the accumulator section as there are rows of keys, anda similar number of typecarriers 514 (Fig. 2) in the printing section, with their respective groups of printing members, ineluding hammers 510.

Depressing numeral keys 117 (Fig. 1) in the rows or banks of the keyboard, projects stops 115 into the paths of counter-driving members 310, each of which is pivoted on a pair of front and rear supporting arms 312, and 311, journaled on the cross shaft 300 and cross rod 301, respectively.

A restraining and restoring bar 205 contacts. the front supporting arms 312 to normally hold the drive members 310 in retired position, against the action of their drive springs 383 which connect the respec- -.tive rear supporting arms 311 and the restraining bar 205.

Turning the main drive shaft 200 journaled' in the side frames 967, rocks a crank 210 engaging a cam-slotted arm 220 fast with the restraining and restoring bar 205 to withdraw the latter and tension the driving springs 383, to advance the racks or drive members 310 until arrested by the key-controlled stops 115 or by displaceable detents 221 in those banks wherein no'keys' have been depressed.

The counters 490 are each equipped with pinions 435 and normally remain disengaged from their drive members 310, but asthe main drive shaft" approaches the end of its forward stroke, it trips well known countersupporting means (not shown) to effect the engagement of the pinions 435 with the drive members. (See Fig. 5.) I

The counter supports are tripped and 1e set through the operation of a swinging rod springs 580 are secured,'to store by. means of radius bars 323 thereon.

journaled I Links 214 connect the swinging rod 308 with cranks 212 on the main shaft 200 to oscillate the 1'00.

The counter drive members 310, on their 3 advance, rock extensions 311 of their rear supporting arms 311 to raise the typecar riers 514,.connected to the extensions by links 515, and position the proper types 561 at the printing line.

A group of printing members for each typecarrier, includes a printing hammer 510 (Figs. 1 and 2) journaled on a cross shaft 500 and driven at the proper time by a spring 580 against a firing pin 562 inline with the positioned type to effect the imprint of the type on the work sheet.

A hammer pawl 511 normally retains the printing hammer 510 in cocked position, and a universal latch 518 restrains the entire series of hammers against operation. Crossover tails 511" on the hammer pawls 511 enable a pawl to the left to release all pawls to the right thereof in the customary manner to print ciphers to the right of a significant digit.

A simple split and normal device is provided to interrupt cipher printing to the right, of well known construction, and for this reason is not illustrated.

As the extensions 311 rock upwardly, they release trip bars 513 which displace the hammer pawls 511 of denominations corre- 525 fast on a cross shaft 500, to rock the cross shaft 500. -Arms 519 on the shaft support a hammer resettingba-il 509, Rocking the shaft 500 on the forward stroke ofthe main drive shaft, withdraws the hammer resetting bail 509 beyond the travel of the hammers 510. 1

At the same time, a link '525. which connects the bell crank 525 to an arm 513 on a shaft 502, rocks the shaft 502 which carries arms 512 supportin a tensioning bail 505, (Fig. 2) to which t e hammer'd'rive springs. i

, A connecting bar 528 pivoted at 538 to the bell crank 525, is slotted to accommodate a stud 555 projecting from anarm 517 to which the universal hammer latch 518 is,

secured, so that after-the individual hammer pawls 511 are released, the hanuner 'reset ting bail 509 withdrawn,- and the hammer springs 580 tensioned. the universal latch power in the.

. I (Fig. 1

messes 518 is lifted to free the hammers to the ac tion of their springs and efi ect an imprint of the types 561 as the main shaf approaches the end of its forward stroke.

Main restoring springs (not shown) effect the return stroke of the main. drive shaft 200, during which the restraining and I'm-- storing frailv 205' retires the counter driving members 310 to normal position. The drive members, on their retirement, turn their counters 490 to register or accumulate thereon the amount corresponding to the values of depressed keys.

As the shaft 200 approaches its normal idle position, and after the amounts have been registered, the returning swinging rod 303, by familiar mechanism (not shown) lifts the counters 490 bodily to disengage the pinions 435 from their drive members 310.

Also, the swinging rod 303, during its restoration to normalposition, presses the hammer resetting bail 509 against the discharged hammers 510 to return them to cocked position where they are held by the/ individual hammer pawls 511, released for action by the retirement of the counter drive members 310 and trip bars 518. The tensioning bail 505 is also shifted to relieve the hammer drive springs 580 of a part of their tension, and the universal latch 518 is returned to effective position.

Carrying mechanisms are provided for the counters to transfer the tens from counters of lower denomination to those of next higher denomination.

Such carrying mechanisms each include a rocker 610journaled on a cross rod 600 and equipped with a carrying dog .610 adapted to engage a toothed ratchet 410 on the corresponding counter 490 to drive the counter one step forwardly.

A spring 680 drives the rocker 610 and its carrying pawl 610 against the ratchet 410, and a trigger 612 having a step can in the path of one arm 610 of the rocker, normally retains the rocker and pawl in cooked or set position.

The triggers are journaled on a cross rod 600 extending between the side frames of the machine, and are held in place by springs 681. I

E a c h counter carries a cam finger Kill so arraifged that as the counter turns from its 9 to its 0 position, the cam finger will wipe past and trip the trigger 612 to free the rocker 610 and its pawl 610 to the action of the spring 680 which drives the pawl into mesh with the ratchet 10 on the counter of next highest denomination, to turn the latter one step.

Means to delay the carrying operation, and reset the carrying mechanism is shown in Fig. 1, but not described in detail, as

the principle of this mechanism is fully dismer is m cocked or set position. Such proclosed in the prior patents referred to.

'sition is sufiicient to state that the tripped carrying mechanisms are reset at the end of each forward "stroke in readiness to be tripped during the return stroke of the main drive shaft, should a carrying operation be amounts on the keyboard controls the operation of the printer section and the groups of printing members. To'utiliiae one or more of the regular counters 490 of the machine on which to effect an accumulation of the number of items set upon the keyboard, i have contrived a means operable from the printer section to trip the carrying mechanism of a selected counter each time an amount is entered on the keyboard and printed. Y

. To this end, I journal a tripping arm or member 1 on a cross shaft 401 mounted in the side frames 967 of the-machine. Preferably, the arm forms a part of a substantially U-shaped rocking yoke or frame 2 journaled on the cross shaft, the arm extending forwardlylto a. point above and adjacent the trigger 612 of the selected carrying mechanism, and having a yielding tappet or finger 3 slidably mounted by a headed pin and slot connection 4.. at its outer end. A spring 5 tends to hold the free end of the finger 3 normally projected beyond the free end of the arm 1, the outer end of the finger having an inclined face Gadapted to wipe idly over the trigger when the arm swings downwardly to 'its set position, (Fig. 2).

The tri") arm. 1 is normally held in idle p0- l'fig. 1) by a link or actuator 8., against the tension of a setting spring 7 tached at one end to the arm. A; shot 9 in the actuator link fits over a pin 10 pro- ]ectrng from a. rearwardly extending crank.

11, preferably forming an integral part of the amp arm 1 or of the rocking frame 2 on which the arm is mounted, and a restoring spring 12 conveniently secured"at its ends to the pin 10and to a pin 13 onthe link, flexibly connects the crank and link, the lat ter being supported and guided in its rectilinear travel by a stud 14; projecting from a fixed plate 420 through a guide slot 15 in the link at one end of its travel. when the hamjection is referably mounted on the units 5" link '8ibythecontact of the projection 18" with the 17 on the link, tensions the superior'restoring spring12 connected to the tripping arm 1 on the opposite side of its fulcrum, which restoring spring, therefore, 6 overcomes 'the trip arm in its elevated ofirermally idle position. A check, 'as an arm 20, connected to the trip arm 1- or to the-rocking frame 2,

contacts astationary part of the machine, as

v the cro'ss rod 402, to'arrest the trip arm in cocked position (Fig. 1) against the tension I of the restoring spring.

1 When no .keys are depressed, the idle ,stro kin-g of themain drive shaft 200 will 39 have no effect on the mechanism for efi'ecting fitem counting, the racks or drive members 310"bein'g arrested by the rack detents 221 before. they have advanced sufiiciently to tenable the trip bars 513 to release the individual hammer 'pawls 511. Consequently, jl'ie units hammer 510 remains cooked and the projection 18 carried thereby, retains the link actuator 8 in retracted position.

Turning the main drive shaft when an 10 ti get up on the keyboard, releases the printing hammers'510, as heretofore ex plained, and the units hammer, as it turns on its shaft 500 in firing, withdraws its projection18 from the path of the toe 17 of the i5 actuating link 8, thereby freeing the link to the action of the tensioned restoring spring "12 which immediately contacts, and draws the link upwardly, guided by the stud 14,

f the collars 16, and the pin 10. The relaxation of the spring 12 also enables the tensioned setting spring 7 to rock the frame 2 and tripping-arm 1' from normal position (Fig. 1) to set position (Fig. 2) during which,-the cam face 6 of the finger or tappet 3'.contacts the trigger 612 and yields rearwardly, to wipe idly over the trigger without displacing the latter, because at that time the carry-resetting mechanism is substantially inoperative, and the displacement of the trigger would have no effect on ,.the counter.

' V The arm 1 may be arrested on its setting stroke by contact with the hub of the 'pinion 435.

1 The hammer cocking bail 509 restores the the setting spring and maintains hammers on the return stroke of the main shaft, durin which operation, the projection 18' on t e units hammer contacts the advanced toe 17 of the actuating link 8 and returns the link to normal position. o

The link, as it retires, tensions the meter ing spring 12, which overcomes the settin spring 7 and swings the rockin frame 2 and tripping arm 1 upwardly unti the finger or tappet 3 contacts the trigger 612. The finger does not yield on the return travel of the arm 1, and the resistance offered by the trigger 612 and its spring 681 to the action of the restoring spring 12 is sufficient to arrest the arm in contact with the trigger until the hammer projection 18 has nearly returned the actuator link to normal position, storing more energy in the restoring spring. Just as the actuator link. is drawn'to itsnormal position, the outer end wall of the slot 9 in the link contacts the pin 10 on the rocking frame 2 and positively rocks the arm 1 upwardly. This'positive action causes the arm 1 to wipe past and trip the trigger 612, whereupon the restoring spring 12 is freed to return the rocking frame to idle position.

The trigger, when tripped, releases the carrying rocker 610 to the action of its drive spring 680, which tilts the rocker, and forces the carrying pawl 610 thereon against the ratchet 410 of the adjacent counter 490 to turn the latter one step and thus frame, which tension is suflicient-to overcome the tension stored in the setting spring by the restoration of the frame to its normal position. I 1

From the foregoing, it will be seen that the automatic counting of items will not occur unless an amount has been set up on the keyboard to permit the release of at least one hammer.

The split or interruption of cipher printing to the right in the printing section, is effected at a point between the hammer corresponding with the counter of lowest denomination reserved for the accumulation of the item count. and the hammer of similar denomination to the counter of highest value in the section reserved for the accumulation of amounts.

It is desirable that a total of the item count registered on the counters to the left of the split, be printed when a total of the amounts or items accumulated to the right of the split is taken, but as the printing of the total of the amounts involves the operation of the units printing hammer 510, means is provided to disable the item counting mechanism during such total taking, to

mit the counters appropriated to register such count to clear, when desired.

Depression of the total key 327 (Fig. 1)

" rocks a lever 317, one arm of which is connected to a slide member 320 guided on studs 358 in the side frame 967, to advance the slide. A shoulder 320 (Figs. 1 and 6) on the slide contacts a pin 454 on an arm 412* projecting from an alinement bar 412 jou'rnaled on a cross rod 403 in the side frames. The slide rocks the alinement bar 412 to .interpose abutments 412 thereon into the paths of the cam fingers 411 on the respective counters to arrest the latter in their zero positions in the customary manner, as

shown in Fig. 6.

The upper edge of the alinement bar lies in front of the crank 11 on the rocking frame 2 and carries a keeper 21 normally out of the path of a lug 22 on the crank. When the alinement bar 412 shiftsto effective position, however, the keeper 21 swings over the lug 22 to .lock the rocking frame and trip arm in cocked position against operation, until the alinement bar returns to normal idle'position, and thus prevents the tripping of the carry and the consequent of the number of items, and the digitof highest value in the total of the amounts.

In order to lock out the automatic means which effects a count of the items set up on the keyboard, so that the machine may be used as anormal machine to accumulate items or amounts to its capacity, I provide a manually controlled device which locks the trip arm 1 in cocked position against the action of the setting spring'i. Such lock may be of any convenient form, but in the present instance, it comprises a foot 23 carried by a stub shaft 24, preferably journaled in a plate 25 mounted over an aperture 26 in the casing 1065 of the machine, above the rocking frame 2. A spring 27 coiled about the stub shaft 24 between the foot 23 and the under face of the plate 25, operates to frictionally hold the foot in adjusted position. Turning a thumb piece 28 on the upper end of the shaft projecting above the plate, swings the foot 23'over the check arm 20 to prevent the latter from rising, (Fig. 5) or shifts the foot away from the'check arm to enable the frame and trip arm to rock to set position.

The foot ca ries an abutment 29 (Figs. 2, 5 and 6) adapted to contact the check arm 20 in case the locking mechanism is operated while the cheek arm is out of its normal position, to thus prevent the effective operation of the locking mechanism. Otherwise,

the foot could be interposed between the check arm and its arresting rod 402 to prevent the return of the frame and trip arm to normal cocked position.

Stops 30 (Fig. 3) on the plate 25 contacted by a pointer 31 on the shaft 24, arrest the travel of the foot 23 in either direction, and the late may bear the Words On and O or other suitable designations adjacent the respective stops to indicate to the operator the position of the locking mechanism.

WVhen the locking mechanism is in effective position, the operation of the machine, with an amount set up on the keyboard, will effect the release by the units hammer, of the actuator link 8, which is drawn upwardly by the contraction of the restoring spring 12 until arrested bythe contact of the lower end wall of the slot 9 in the link I with the pin 10 on the rocking frame 2. The foot 23 prevents the operation of the rock- Without departing from the spirit and scope of this invention.
