Toallwlwmitmay concern:

Be it known that I, Cani. A. Snswsox, citizen of the United States, and resident of the borough of Manhattan, city of New York in the county ofNew York and State of New York, have invented certain new and useful Improvements in Calculating Machines, of which the following is a specification.

My invention relates to calculating chines and more particularly to spiral removing mechanism for such machines.l

In calculating machines, in which carrying mechanism of certain kinds is employed to carry from a wheel of lower order to the next wheel of a`higher order throughout the series, there is a likelihood of developing what is known as spirals during the carrying and clearing operations. That is to say the numerals on the re 'ster wheels, exposed at the sight-openings in the totalizer frame, instead of appearing in a straight horizontal line will appear in a spirally disposed arrangement which sometimes results in the im roper actuation of the register and gives a alse reading on the register wheels, as is well understood in the art. v

The main object of my invention is to provide simple and highly elicient rectifying mechanism for overcoming t h`is difficulty and for automatically aligning the wheels after each operation thereof to remove any spiral that may develop.

A further object of my invention is to provide simple and eicient mechanism ofthe character specified which maybe readily incorporated in existing computing machines vwithout modifying, or materially. modifying, the structural features of such machines as they now exist.

To the above and other ends which will hereinafter appear, my invention consists in the features o-f construction, arrangements of parts, and combinations of-y devices set forth in the following specification and particularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference characters indicate corresponding parts in the different views,

Figure 1 is an enlarged detail fragmentary' fore-and-aft vertical sectional view showing a portion of the actuator and a portion of a totalizer of a Remington accounting machine.

Figure 2 is a like view of the same kshowing the parts in different positions from` those represented in Fig. 1.

Figure 3 is an enlarged detail perspective view of the aligning bar and means associated therewith for controlling the movement thereof.

Figure' 4 is an enlarged detail fragmentary front view of the parts represented in Fig. 3 together with certain of the wheels of the totalizer with which the aligning bar coacts.

Figure 5 is anenlarged detail perspective view of the means by which the spring for the aligning bar "is retained in place.

I have shown my invention in the present instance embodied in a Remington accounting machine of the character disclosed, for example, in the patent to John C. Wahl, No. 1,270,471, dated June 25, 1918, in which the devices of the present invention may be readily embodied without modifying, or materially modifying, structural features of said machine as they now exist. YIt should be understood, however, that the invention is not restricted to embodiment in such machines but may be employed wherever found available in various styles of computing machines.

lThe Remington accountingmachine is a combined typewriting and computing machine in whlch one or more vertical totalizers are carried by a truck connected to the carriage of the ty` writing machine to travel therewith. ach vertical totalizer carries registering mechanism controlled by actuating mechanism carried by the frame of the machine and o i ated b the numeral keys of the t pewriting mac4 ine. When a totalize has geen brought to the computin zone an actuation of a numeral key wil register in said totalizer a number according -to the value of the key which has been actuated, either for addition or subtraction, in accordance with the setting of the machine. The truck advancing one step at each operation of a numeral key. brings wheels of the totalizer successively into en agement with the master wheel or device o the actuating mechanism for actuation thereby. When used for addition, for example, each register wheel in making a complete revolution and in moving from the 9 position to the 0 positionv will result in the carr ing mechanism turning the register wheel o the next higher order one space adding one thereto, this movement at times being transmitted throughout the series from a wheel of the lowest order to a wheel of the highest order.

In the accompanying drawings I have shown only so much of the Remington accounting machine as is necessary to arrive at an understanding of my invention in its inclusion therein, the mechanism 'of this machine being well understood in the art and fully disclosed in the said Wahl patent.

A portion of the truck, by which one or nioie vertical totalizeis are carried, is indicated by the reference numeral 1 in Fig. 1. Each totalizei comprises a frame Q.' detachably connected to and adjustable to different positions along the truck 1. Each totalizer frame 2, as ordinarily constructed, carries a series of dial wheels 3, each provided with a gear wheel 3a; a series of meshing idle wheels 4; a series of gears 5 each having thirty teeth which mesh with the gears et; and a series of locking wheels 6. Each gear 5 has fixed on the left-hand side 'thereof a wheel a formed with three carrying teeth Z) spaced apart at intervals of ten teeth of the coiiipanion gear 5. Each gear 5 also has fixed thereto a wheel 7 arranged to the left of the wheel a and having its periphery formed with three notches 8 arranged at intervals corresponding to the positions of the carrying teeth Zi. Each wheel 7 constitutes a member of a Geneva gear which coacts with the companion gear, star or locking wheel 6. Each wheel 6 carries a gear 9 on the righthand side thereof with which the carrying teeth Zi coact, and also has on the left-hand side thereof a gear (not shown) which meshes with the wheel 5 of the next higher order. When the teeth of a wheel 6 engage the periphery of the companion wheel 7 said wheel 6 is prevented from turning. lVheii, however. a recess 8 is brought opposite a tooth of the companion wheel 6 as shown in Fig. 1, a carrying tooth engages the associated gear 9 and turns said wheel 6 one unit; a tooth of the wheel 6 passing through the registering recess 8 at this time. This turning movement of the wheel 6 is transmitted through the gear on the left-hand side thereof to the engaged gear 5 of the next highei` order and such motion in turn is transmitted to its dial wheel. In this manner motion may be transmitted throughout the series from the lowest to the highest order wheels to carry successively through all of the register wheels.

The truck 1 moving with the typewriter carriage brings the totalizer to the computing Zone and the wheels 5 are brought successivelyv by a. step by step movement in to mesh with a master wheel or device 10 w to be operated successively thereby at succesmaster wheel 10 is carried by an actuator frame secured to the frame of the typewriting machine. Various parts of the actuating mechanism by which the master wheel is controlled are carried by this frame, certain only of such parts being illustrated. This actuating mechanism comprises a series of links 12 each connected at its lower end to the respective key lever of the numeral key for said link. The upper end of each link is pivoted to the associate socalled fan 13 that includes part of the full stroke mechanism and means by which motion is transmitted to various parts of the actuating mechanism. A cam 14 on each fan 13 coacts with a universal bar 15 carried by and adapted to turn in bearings in parallel arms 16 fixed t0 a rock shaft 17. Also fixed to the shaft 17 is aA crank arm 18 to which a link 19 is pivoted at 20. The upper end of the link 19 is .slotted at 21 to receive a headed pin 22 carried by a master cam 23. This cam is xed on a shaft 24: and is operative on a certain master dog (not shown) and on other devices, which for the purpose of my present invention need not be considered further than to point out that the parts in question operate in the usual manner, except that a certain aligning dog usually employed in the Remington machine and co-operative with the wheels 5. is omitted. An additional crank arm Q5 fixed on the rock shaft 17 carries a laterally projecting pin or roller QG co-operative with a cam 27. This cam is formed in a member 28 pivoted at 29 and carrying a so-called locking dog 30 which normally engages the master wheel 10 and serves to definitely align the master wheel and hold it in position during the time said wheel is not being rotated by the depression of a key.

illy improved aligning mechanism includes a crank arm 31 fixed on rock shaft 21 and carrying a laterally projecting pin 32 that projects into an opening 33 in a carrier 3l pivoted on a. headed pin 35 secured to a frame plate 3G of the actuator. As the shaft 2t receives a clockwise movement from its normal position as the arts are viewed in Fig. 1, the pin 32 wil be forced against the wall 33 of the opening in the carrier 34:. turning the latter from the Fig. 1 to the Fig. 2 position. The forward end of the carriei' 34 carries laterally projecting lugs 37 between which is received a depending arm 38 at the right-hand end of an aligning` bar or plate 39. A pivot pin 40 extends through the lugs 37 and the arm 38 transversely of the bar 39 lto pivotally connect the aligning bar at one end to its carrier 3%. The lower end of the arm 33 is formed with an enlargement 41 provided with an opening through which a. pin 42 extends. This pin is secured at its inner end to and projects laterally from the carrier 34. The diameter of the pin is smaller than that of the opening in the arm 38 through which the pin extends so as not tointe'rfere with the pivotal movements of the aligning bar on its carrier 34. A coiled expansion spring 43 surrounds the pin 42 and bears at its inner end against the enlargement 41, and at its outer end against a stop or head 44 carried by the pin at the outer end thereof. I prefer to detachably connect 4this head to the pin as best shown in Fig. From this view it will be seen that the pin 42 is provided with two recesses, slots or cutouts 45 on opposite sides thereof and near its outer end. This leaves an interniediate web 46 .between the slots, and leaves a head 47 at the end. The detachable head 44 is in the nature of a washer of a thickness ycorresponding substantially to the width of the slots 45 and formed with a laterally extending slot '48 corresponding` substantially to the thickness ot the web 46 and with a. central depression 49` corresponding substantially to the shape and dimensions of the head 47. It will be understood that when the spring 43 is maintained contracted on the pin 42, the head 44 may be slipped laterally on the pin through the openings 45 therein until the head is centered on the pin. It' the spring is then released it will force the head 44 to the right and seat the head 4T in the recess 49, thuslocking the head 44 against accidental detachment, and holding it in this position so long as the force of the spring 43 is exerted thereon, but enabling the head to be readily detached when desired.

It Will be understood from what has been said the force of the Spring 43 is exerted to hold the arm 38 against the carrier 34, or to return it to such position if moved therefrom. The spring therefore tends to hold the aligning bar 39 in the normal position, shown in Fig. 3, relatively to the carrier 34, so that the two may swing together as one part around the axis of the pivot 35, which is parallel with the aligning bar and with the axis of the wheel 5. The left-hand end of the aligning bar 39 is provided with a locking finger or lug 50 co-operative with the locking or holding device that is automatically thrown into and out of engagement therewith, as will hereinafter appear. I prefer to guide this finger 50, in its movement with the plate 39 and the carrier 34, in a guide slot 51 ot a bifurcated guide member 52 secured at to the plate, 54 of the actuator frame. In order to further aid in guiding the carrier 34, and to provide means for limiting its pivotal movements from and back to -normal position, I prefer to employ a headed pin the stem of which extends through a slot. 56 in the carrier, as shown in Fig. 2. This pin is secured to the frane plate 36 and the head of the pin overlapping the right-hand or outer face of the carrier guides'the latter at its foward end between said head and the frame plate 36.

From an inspection of Fig. 4l it Will be seen that the upper engaging edge 39A of the aligning bar is of angular shape in cross section to lit snugly between the teeth of the wheels 5. Then therefore the bar is forced into place between said teeth the wheels engaged by the bar 'will be properly aligned, It is not necessary to have the aligning bar coact with the right-hand or lowe'st order wheel inasmuch as said wheel is properl aligned by engagement with the master wieel, which is itself aligned and held in proper position by the locking dog 30.

The carrier 34 is turned on its pivot 35 from the Fig. 2 to the Fig. 1 or effective position, by a contractile spring 5T stronger than the spring 43 and connected at one end to a pin 58 which projects from the frame plate 3G, and connected at its other end to a pin 59 which projects laterally from the carrier. The movement of the aligning' bar 39 with its carrier to the releasing position is effected by the camming action of the pin 32 against the carrier and against-the torce of the spring 5i'.

As thus tar described the construction is such that the tirst part ot the depression of a key is effective to swing the universal bar l5 `before any motion is transmitted to the master wheel in a manner to be presently described. This movement ot the universal bar results in moving the parts controlled thereby from the Fig. 1 to the Fig. 2 position, thereby withdrawing the locking dog 30 from the master wheel 10 and withdrawing 1the 'locking bar 39 from engagement with the wheels'rthat coact therewith. In this movement, the bar,39 swings bodily with its carrier 34 around the pivot and simultaneously disengages all the wheels with which it coacts. The parts are held in this position by the universal bar bearing on adwell 14a ot the cam 14 ot the actuated fan 13 during part ot' the remainder of the. down stroke of the key, and until the universal bar clears the dwell 14"l and is freed from control ot the depressed key for independent return movement.

Itis not until after the above described preliminary operations of releasing the master wheel and the wheels 5, etc., have taken place that the master wheel is tui-ned the requisite distance during, say, the last half oli/a. depression of a key to set up a number in the register. The operation of the inaster wheel is ett'ected by a series of goosenecks 6() each formed as a part of a carrier 6l mounted to turn on the supporting rod 62 on which the t'ans 13 also are mounted to turn. Each carrier 6l is associated with ins lll

' wheels and o rated by a fan 18 through an interm iste lost motion connection omprising a pin 68 projecting laterally f1 `om the carrier into s slot 64 in the companion fan 13. This lost motion connection enables the above `described preliminary o ration to be effected before the upper wa 64'* of the slot in the o rated fan reaches the pin 63 and takes uptic carrier of the goose-neck to cause an operation of the master Wheel. It will be understood that cams 65 on the different goose-necks are so shaped that each gives a different extent of throw depending on the value of the key to which the gooseneck is operatively connected. Each cam terminates in a slot 65a which acts as a dwell st the high point of the cam. These goose-necks operate on pins or rollers 66 carried by arms 67, only live of which are shown in the resent instance. These arms project from t ie differential shaft 68 of the machine end radiate from said shaft to bring the pins 66 thereon into cri-operative relation with the cem 65. The usual means (not shown) are provided for transmitting to the master Wheel the different extents of movement given to the differential shaft 68.

Thus fer l heve described in detail only the disengaging movement of the aligning plate or bar 39 from the wheels 5, it being understood that the engagement of the plate with seid Wheels and the aligning thereof does not taire place until after the master Whe-el has been actuated. n engaging the and aligning them, and thereby aligning the dial Wheels it is highly desirable cause the aligning bar 39 to engage the Wheels successively' beginning at the right. ln order to effect this result l provide the following means co-operative with those hereinbefore described.

Referring especially to Fig. 3, it will be seen that the diderential shaft G8 carries a crank arm 60 provided with a laterally projecting pin 70. This pin is received 1n a cam slot 7l of a locking member 72 mounted on e heeded pivot pin 7 3 secured to the frame plate 54. The upper wall. of the cam slot continues as a surface 74 which when the member 72 is in the actuated position is concentric to the center of the shaft 68. This surface 74 acts as a dwell to hold the locking member in its actuated or locked position until the pin 7() re-enters the cam slot 7l and withdraws ,the locking inember to releasing position, shownhin Fig. 3. The preliminary operations hereinbefore described et the first part of a key depression .l moves the aligning bar down to simultaneouslv disengege the wheels 5, and leaves the locking linger in the lower end of the slot 5l. During a further depression of the key the differential shaft 68 will be rocked by tlie'nctnsted goose-neck s distance deon thevvalue of the particular key depressed. The first part of this movement of the differential shaft is efectivo to turn the locking member 72 in an anti-clockwise direction, as the parts are viewed in Fig. 3. This brings the upper hook-like engaging portion 75 over the finger 50 and prevents an upward or return movement of that end of the aligning bar. The construction and arrangement 0f the parts of the Remington accounting machine are such that near the termination of the down stroke of a key the universal bar 15 drops olf the dwell 14 of the actuated fan 13, allowing the universal bar and the parts controlled thereby to return to their normal positions. Un the other hand, the actuated se-neck, the differential shaft 68 and-t e parts controlled thereby do not return t0 normal position until about the termination of the 11p-stroke of the key. By controlling the carrier 34 of the aligning bar 39 from the universal bar, and controlling the lockin member 72 from the differential shaft 68, am enabled to move the aligning bar down and simultaneously disengage all the wheels 5 at the rst part of the down-stroke of the key. When this movement is completed the member 72 is moved to locking position to hold the free end of the aligningbar against turn movement. Before the down stroke of the key is completed the universal bar returns to normal position allowing the carrier 34, under the force of its sprin 57, to move up to the position shown in ig. 4. The e ect of this is to carry the right-hand end of the aligning bar up with the carrier while the lefthand end thereof is held by the locking member 72; the lookin bar at this time overcoming the force of t e spring 43 and turning on the pivot 40. The locking bar is thus moved relatively to its carrier 34 and is dis d in an oblique position, its engaging edge assuming an angular position relative to the axis of the wheels 5, as shown-in Fig. 4. It is with the parts thus disposed that the right-hand end portion of the align ing bar successively engages Avvheels 5 of the lower orders near the right-hand end of the series. The parts remain in this position until near the end of the return movement of the depressed key, when the associate l se-neck releases the differential shaft 68. As the latter returns to normal position the locking member 7 2 will return to releasing position, thus freeing the aligning bar. When thus freed the spring 43 is eective to turn the aligning bar on its pivot 40 while the carrier 34 remains at rest. The effect of this ivotal movement of the aligning bar is to e evate or advance the left-hand end thereof, thus bringing about a successive engagement thereof with the remaining wheels 5 to the left; or as many of them as it may be necessary for all practical purposes to engage. It has been pointed out that the lli master dog 30 coacts with the master wheel so that in practice it is unnecessar to align the righthand or lower order whee 5 by the aligning ba'r 39. It is also unnecessary in practice for the bar 39 to coact with one, or even several of the wheels to the left of the alining bar. Therefore when I refer herein and in the accompanying claims to the aligning bar engaging a series of Wheels, it will be understood that the entire series of wheels 5 are not necessarily included by such terms.

The teeterin movement, of the aligningr bar so as to a vance first one end thereof and then the other into engagement with the wheels and thus successivel engage them, I regard as an important eature of my invention, as is the control of the aligning bar by the universal bar anddiiferential shaft for bringing about the successive and lIropei'ly timed operation of the aligning The operation of a totalizer mi ht be one in which carr in is done to al carrying wheels above t e owest, or one in which the totalizer is cleared by addin to aiegistered number the complement 0% that number. Probably trouble caused by the spiral in clearing operations is more annoying than that caused by it/in carrying operations, since clearing operations are frequently performed, whereas carrying operations in which carrying is done to several wheels at a time are performed only occasionally or rarely; the spiral not occurring so as to be troublesome except when a number registered at the sight-openings contains a long succession of either nines or naughts.

yIt will be understood that the greater the number of register wheels, the greater the liability of spiraling, since the longer the series of wheels the greater is the amount of lost motion in the carrying gear train. In a totalizer'carrying a suiliciently long series of wheels, tlie spiral would absorb all of the motion derived from a carrying wheel of the lowest order, so that not any-of it would be imparted to the highest carrying wheel. In the `present instancel I have shown fifteen totalizer wheels, a rather long series; and in practice the justifyin mechanism of my invention has proved e cient iii use with such a `totalizei.

It will be observed that the construction is such that the spring43 is rendered alternately eifective and ineil'ective to produce a, pivotal movement of the aligning bar 39 around its pivot that the spring 43 constitutes a connecting means by which the aligning bar is connected to its carrier 4t or moving means, and that the axis'of the pivot 40 is contained in a lane at right-angles to tlie axis of the whee 5 and the carrier 34 swings in such a plane so that the aligning bar swings on its pivot 40 in a plane at right-angles to the plane of movement of the carrier 34 to eiiectv the described movements of the aligning bar.

Various changes may be made without departing from my invention.
