Patented Sept. 1%,2'5233. Serial No. 474,747.

T 0 all whom it may concern Be it known that I, From L. MANNY, a citizen of the United States of America, and resident of Benton Harbor, Berrien county, Michigan, have invented a certain new and useful Improvement in Computing-Machines, of which the following is a specification.

My invention relates to adding or computing machines in general, but more par' ticularly to that type in which a series of. slides or push-bars, each provided with a series of teeth adapted. to be engaged by the point of a pencil or stylus, are employed for operating a similar number of numeral wheels, each numeral wheel having a series of teeth numbered from naught to nine, in In a computing machin of this particular character, the said slides or push-bars are arranged side by side in a horizontal plane, with the teeth oi each slide or bar held normally in alineinent' ith those of the others; and with this arrangement each bar has nine teeth, the ninth tooth of each bar being at the extreme end thereof, and there being ordinarily nine of. said slides or bars, whereby the machine is capable of handling numbers involving high as nine digits. Each bar actuates its allotted numeral or ratchet wheel in accordance with the numeral selected on the slide or bar-that is to say, depending upon the particular tooth of the bar or slide engaged by the pencil or stylus of the operator. \Vhen released, each slide or push-bar re-- turns to normal position, the forward actuation of the bars' being made variable by a stop which cnga es the pencil OIKStYlUS of the operator. T isinaehine is simple, and has always been satisfactory for certain pur poses, but its range of usefulness has always been more or less circumscribed and limited- The object of my invention is, therefore,

machine of this character having a wider range of utility than heretofore; to provide a computing machine of this general charact'er in which provision is made for printing a list of the numbers to be added, and for printing'totals and credits; to provide a machine of this character by which addition, division, subtraction, multiplication, etc, may be carried on, and iii which the i said provision for printing may be disconnected and thrown out of use whenever ms is desirable; to provide-a machine of this character in which provision is made tor automatically feeding both the paper and the ink ribbon employed in printing a list of the numbers to be added, or in printing the totals and credits; and to provide (cu tain details and features of improvement and combinations tending to increase the general eiiiciency of a Computing machine of this particular character.

To the foregoing and other useful ends. my invention consists in matters hereinafter set forth and claimed.

Fig. 1.7 is a perspective of one of the locking dogs on the register cl inech-- c in long1 prises a box or c'asing A for inclosing the greater portionot the mechanism, and having side chambers a and a for inclosing certain operative elements at the sides of the machine. Said leasing has a top Wall a. provided with a slot a for exposing the register wheels B,and a larger rectangular opening a for exposing the numeral teeth of the computing members or push-bars C. The wheels B each have ten ratchet teeth I) With numerals from naught to nine on the beveled faces thereof. Said Wheels are all arranged side by side on the shaft 1), which latter has. longitudinal slots 1). The said wheels turn on the shaft 1), but the disks B have projections that extend into the slots b and can only turn with the shaft. Each disk has a cam portion b and a finger b. (See Fig. 15.)

Each register wheel has a ratchet wheel 11 on the right hand side thereof, and a spring pressed dog 6 on the other side thereof, said dog having a finger b (see Figs. 12 and 15). It will be seen that the ratchet wheel of the hundreds register'wheel is on the side toward the tens register wheel, and

that the dog I) of the said hundreds register wheel is on the side, toward the thousands register wheel. face in the same directionthat is to say,

toward the knob 71* at the end of the cylinder shaft 1), and the fingers b of the dogs all extend in the other direction. Thus the dog I), of the units wheel rides on the periphery of the adjacent disk B, and ts finger 7 extends beyond said disk and overhangs the teeth of the ratchet wheel 6 on the tens register wheel. This arrangement is uniform throughout the series of register wheels, so that whenever a finger b drops into the cam portion L of a disk it engages a tooth of the ratchet wheel on the next register wheel and gives the latter a single step or, rotation forward a distance equal to one tooth, thereby giving a difl'erent reading. Each register wheel, therefore, is capable, iupon being given more than a complete rotation by any two or more successive operations, to add one to the reading on the next wheel, as is usual in addition. This,.

- however, will hereinafter more fully appear.

By the knob 11*. (see Fig. 13) which is slidable on the cylinder shaft and held in normal position by a spring, the said shaft can be rotated to bring all the register wheels to zero that is to say, for the purpose of bringing all such wheels back to starting point. This is by reason of the fact that said shaft when rotated causes the finger b to swing around until it strikes the finger L, and when the shaft stops with the pin 6 on the knob, and .in engagement with a notch on the bearing 6 the disks B, are then all locked in position with their fingers all pointing directly upward, and with The ratchet. wheels 2) all:

the fingers b all resting in position justin front of the fingers Z)". When rotated or while it rotates, therefore, each finger 1) leaves the finger Zr and continues to ride around upon the circular periphery of the adjacent disk B, and does so until the cam portion 6 is reached, ,when engagement is had with the next wheel and one added to the reading of such wheel. As stated, however, all this will hereinafter more fully appear.

The cylinder shaft b is mounted in bearings carried by the yoke-like frame B which latter has its forward end pivoted to the casing at b. The free or swinging end of said yoke normally rests upon a pin 6 on the inner side of the casing. The said yoke also carries a transverse rod or pivot Z) upon which are mounted the dogs I), at one side of the axis of the register wheels. At the other side of the axis of the register wheels, and between the same and the free or movable end of the yoke, the latter is provided with a transverse rod or pivot b upon which are mounted the dogs 5 It will be seen that the dogs I) are subject to the tension of their springs b which are carried on a cross rod 1) on the yoke. The tension of these springs can be regulated by screws 5 extending throughthe rear transverse portion of the yoke. These dogs 5 engage the faces of the teeth I) to prevent backward rotation of the register wheels. The dogs (J engage small recesses 6 in the backs or beveled sides of the said teeth b, and thus normally lock the register wheels against forward rotation. (See Fig. 12.) These dogs I) are subject to the pressure of springs I). .It will also be seen that these dogs I) are provided with fingers I) by which they are raised out of engagement with the register wheels when it is desired that one or more of the latter shall rotate. The dogs I) may all be raised out of engagement with the register Wheels by means of a rotatable cam shaft I) mounted transversely on the yoke B The stop bar D extends transversely of the machine between the register wheels and the faces of thecomputing bars C, and has upright side portions pivoted at d to the sides of the casing. Longitudinally extending bars d have their ends held normally in engagement with the upright side portions of the stop bar D, and are mounted to slide on the rod 1), by reason of slots therein, as shown more clearly in Fig. 7. At. their other ends these bars at are connected by a lock; ing bar d", which latter is normally held out of engagement with the register wheels, by a spring orsprings d Each register wheel has one of its teeth 7) provided with a finger b and the dogs b have cam portions b adapted to be engaged T thereof. The under sides of the forward.

is given a complete rotation, its finger b engages the cam portion Z on the wheel ahead, and thus the latter wheel is permitted to rotate one step. The cam portions 1) all point toward the units wheel. For example, the cam portion 6" on the tens wheel is operated by the finger 6 on the units wheel; the cam portion 1) on the dog of the hundreds wheel is operated by the finger I) on the tens wheel; and this arrangement is preserved throughout the series of register wheels. I

The computing bars 0 are provided with numeral teeth 0, adapted to be engaged by the point of a lead pencil or stylus, in the usual and well known manner. These bars are all arranged side'by side in a.substana plate or table 0 extending transversely of the machine, and supported on the casing ends of said bars are provided with racks 0 adapted to engage segment gears a mounted on a transverse shaft 0. These segment gears are adapted to rest normally upon a bumper a, and are operated by springs 0, whereby the rack and pinion connections thus provided cause the computing or pushbars C to return to normal position when released. Each computing or push-bar is provided with a ratchet tooth rack C havment with the stops 0 on the computing bars. With this arrangemen the ratchet tooth rack bar C normally occupies the position shown in Fig. 7 relatively to the computing bars. The teeth a are adapted to engage the teeth I) of the register wheels, whereby the latter are rotated in accordance with the actuation of the computing bars that is to say, in accordance with the numerals selected on the computing bars when the latter are actuated. The pencil or the stylus of the operator, when it strikes the stop bar 1), moves the locking bar (1 into engagement with all the register wheels, thus preventing undue rotation of said 'wheels at this time. 'Each bar C carries a cam track 0 adapted to engage the corretype bars C bear upon the under surt'aceot the plate or table a, and are secured at their forward ends to the computing bars by screws 0. Each type bar carries at its forward end a wheel or roller adapted to engage a cam lever E carried on a transverse pivot e. The paper F for printing is fed from a roll f around a transverse rod f, thence upwardly and around a wheel then through a narrow slot or channel and then outwardly through a continuation of said slot or channel 1, it being observed that by an opening f the said paper is exposed for the full width thereof at a point directly above the hammer G. The paper feed roll f has a ratchet wheel f adapted to be engaged by a do or feed bar H, which latter is slotted and mounted to slide upon screws or pins h, in the manner shown more clearly in Fig. 7. The paper is held in contact with the roll f? by a second roll f The wheels 0, which are on the typebars, engage the upper edge of the transversely extending plate of the lever E. The finger c engages the roll h, which latter is on the bar 9 and causes the hammer to be depressed. Vith the arrangement shown, the paper 'is fed forward each time the units bar C is operated. In putting down numbers, the operator works from left to right, so that the units bar is always the last one to be operated for any number consisting of more than one digit.

The hammer G is mounted upon parallel side bars 9 which are pivoted at 9, said hammer being controlled by a spring g connected between the casing and the rear end of the bar g. Normally, therefore, the hammer G, which may be faced with rubber, oc cupies an elevated position, as shown in Fig. 7. The bar 9 has a lug 9 adapted to be en gaged by-a. hook g pivoted on the side of the casing. This book is controlled by spring [1 causing it to press normally against the uprightsidebar or portion of the stop bar D (see Fig. 7). A spring 12 keeps the bar H normally retracted and out of engagement with the ratchet wheel f. The bars 9 are provided with depending bars g which take over the upper edges of the bar 9 and which have slots 9 that slide on pins on the casing. These bars 9 are held normally down by springs g which connect their lower ends with the casing. In this way the hammer G is held normally in the desired positionthat is to say. just "out of engagement with the paper, as shown in Figs. Tand 22.

A lever I pivoted to the inside of the easing at i is provided with a pin 2" for engagingoneot the side bars 9, as shown more clearly In Fig. 8. A vertically disposed key J, mounted to slide up and down, has its lower end ada. to engage thesaid lever I, as shown in ig. 8. When this key is denot locked down by the key J. The key J is provided with a notch j adapted to engage the edge y" of the casing, whereby the said key and the lever I, and thereby the hammer G, can be locked in a depressed position, lVhcn this is done, the actuation of the hook or dog 9 does not release the hammer and no printing is done, as will be explained. It is possible, therefore, to actuate the register wheels without operating the hammer, which does the printing. The units computing bardoes the printing, as stated, by reason of the fact that a bar or dog L is arranged to engage the ratchet wheel f at one end, and carried on the segment gear 0 corresponding to the units bar. This bar or feed pawl L has a slot Z adapted to engage a pin Z on the said segment 0 of the units computing bar. A spring Z controls the operation of the said feed pawl L, and the latter is provided with acam portion Z adapted to engage a pin Z to throw it out of engagement with the ratchet wheel f. When the units computing bar is moved forward,,the feed pawl L is pushed forward, and when the said units bar is released and allowed to fly back to its normal position, then the pawl L engages the ratchet wheel f and moves the paper ahead one step The cam portion Z and the rod 2 cooperate to throw the feed pawl L out of engagement 7 with the ratchet wheel f, as shown in Fig.

8. It will be seen, therefore, that the ham- Iner G is tripped and operated each time a computing bar is operated and that the paper feed mechanism is 0 erated each time the units computingbar is operated. The actuation of any computing bar causes the lever E to depress the hammer, and thesamc becomes locked in suchdepressed position by the hook or dog g. When the operators pencil or stylus reaches the stop bar D, and when the latter is moved forward, the harm mer is then released, in the manner explained, and allowed to fly upwardly against the paper. Every time the hammer flies upwardly, its blow is received by a type on the lower surface of the corresponding computing bar, so that a correct record is kept of each actuation of each bar. If it is not desired to use the printing mechanism, then the key J is pressed downward to lock the hammer in an inoperative position, as previously explained. When the register to depress the] backward rotation thereof.

wheels are reset by the rotation of the cylinder shaft L, the cam M thereon is rotated. which cam engages and actuates the end of the bar H, as shown in Fig. 6. This causes a readjustment of the paper into position for printing. After the numbers are all set down and printed, the paper is then run out by means of the rack N adapted to engage the pinion n on the end of the feed roller f Normally this rack occupies the position shown in Fig. 22, being provided with a longitudinal slot 'r," having an upturned portion 11 adapted to normally engage a pin or guide rod n. The outer end of the rack has a handle N", and is also provided with a shoulder a" adapted to rest normally against the edge of the casing, as illustrated. Thus when it is desired to run the paper out of the machine, so that the printed portion thereof may be torn off, it is necessary to raise the handle 71. for the purpose of disengaging the shoulder a and-causing the rack N to engage the pinion 01.. When this rack N is reversed and moved in the opposite direction, then the paper is run. back into the machine. .l n such position, however, it is back of the opening f, and it is necessary at this time, therefore, to actuate the paper forward again and into position for printing. This is done, stated, by means of the cam M when the register wheels are reset or returned to zero. In resetting the register wheels, it is necessary to raise the handle 0, which secured to the cam shaft 1', whereby all of the dogs I) are raised out of engagement with the register wheels.

The ink ribbon P is.carried on two rolls 7? and 7) and travels. through guides 79 thus bringing it directly between the paper and the type on the type bars, and. directly over the opening f \Vhenever the hammer is actuated, therefore, it presses the paper against the ink ribbon, and presses the latter against the type, much after the fashion of an ordinary typewriter. It will be seen, however, that the hammer serves the function of a platen, and is movable, whereas the type remains stationary during the printin Each time the-bar g descends it strikes the upper end of the bar Q. The lower end ofthe latter operates a lever g, which is pivoted'at g and controlled by a spring (1 The other end of this lever q carries a pair of feed pawls 9 q controlled by a spring 9 The pawl q is adapted to engage a ratchetwheel 5 on the roll p, while the feed pawl q is adapted to engage a ratchet wheel 9 on the roll 7). A pair of pivoted dogs 9 are adapted respectively to engage the ratchet wheels Q6, 1 to prevent As shown in ig. 18, the vibration of the hammer G will cause the bar Q to actuate the feed pawl q against the teeth of the ratchet wheel q,

thus Winding the ribbon on the roll 1), and unwinding it from the roll 7). An automatic shifter R is, howeven'provided for reversing this motion. This shitter its upper end pivoted at 'r, and is provided with a lower upturned port-ion r adapted to play between the two rolls, and to be engaged by the ribbon thereon. The said shifter also provided with a diamond-shaped opening 1- having a flat spring r adapted to engage a pin 7 on the stationary plate r of the frame or casing of the machine. The pins and g, mounted respectively on the dogs 9 and g, are carried in and engaged by the opposite ends of the diamond-shaped opening 1*, (see Fig. 18.) The shifter R has a pair of pins 1' which embrace the upper portion of the spring 9 as illustrated. Now. assume that the roll 7) is gradually ini creasing in size, and therefore gradually pushing the shifter R over toward the other roll. direction is opposed by the 'springr until the same has been bent suiiiciently to snap o er the pin 1". When this is done, the dog 9' is disengaged from the ratchet wheel 1, and the dog 9' is caused to engage the ratchet vheel {1 Also the feed pawl is disengaged from the ratchet wheel g, and the feed pawl 7 is brought into engagement with the ratchet Wheel 9 The spring r is, of course, stronger than the spring 9 whereby the latter is placed under tension to" hold the feed pawls to their work until the roll, either one, is full and ready to reverse. When this is done, the continued operation of the hammer G causestl e bar q to operate the roll 77, causing the ribbon to Wind thereon, and causing the said ribbon to unwind from the roll. 7). Thus the hammer Works the ribbon feed mechanism, and the latter is automatically reversed in its'operation as soon as either ribbon roll becomes wound or loaded to a certain extent, namely to an extent sutlicient to push against the portion r, and thereby snap the shifter R over to the otlier-pbsition.

It is often desirable to print without op" erating the registering mechanism, in putting down totals, or as in putting down credits which are not to be added with the other numbers. F or this purpose I provide a pair of keys S and T, the first being the total key and the second the credit key as will be seen by the indications on the u1' per surfaces thereof. Referring to Fig. 2, it i ill be seen that the key S engages one end of a. pivoted lever U, and that. the key T ongages tneothcr end of said lever, each key bcuig held normally in elevated position by a uitablc Spring, in the manner illustrated. Tl. lever U held in a imrmally lim'izonta ion by a spring .1; A bell crank V is n h side of the casing and pro The movement of the shifter in this.

vided with a pin o adapted to engage one end of the lever U. This bell crank operates a slide or bar \V which moves in a slot u; in the frame or casing of the machine (see l ig. H1.) At its forward end the said bar W has an enlarged portion w provided on its l-iiwer surface with a credit type t and a total type .9, adapted to alternate above the hammer and the ink ribbon, whereby one or the other may be used for making an im' pression on the paper. If it is desired to set down a credit, then the key T is pressed and the type If is thereby brought'ihto position for printing at the right'of the number put down. It a total is to be indicated, then the key S is pressed, thereby bringing the type 8 into position to print. on the paper. lVhen the key S is pressed, the bar WV moves toward the said key; but when the key T is pressed, then the bar moves away from said key. Each key is provided with a lever X for lifting the rear end of the yoke B said levers being pivoted at 00 upon the frame or casing of the machine. These levers engage pins 2: on the said yoke, and thus lift the latter sufficiently to bring the register wheels out of engagement with the ratchet teeth 0. In this way printing can be acc oinplished without registering. Also, by raising -the knob U the register wheels Willbe lifted out" of engagement with the computing bars, and thus an y of the latter can be operated with out causing the computing mechanism to operate. In other words, the computing bars can be used for printing without operating the computing mechanism-that is to say, without operating thewheels B. On the other hand, as explained, these wheels can be operated without operating the printing mechanism, by simply setting the key J into position to hold the hammer against upward movement. When one of the keys S and T is pressed, it throws the register wheels B out of operative relation to the !i1}ilt1ting bars, and throws the bar W into position to print either the character C or T, to indicate either a credit or a total. When this done, and when one of the com puti. hers is then operated, or each time a computing bar is then operated, the hamnier prints both the numeral or numerals on said computing bar or bars, and also the c miracle-r C or T, as the case may be. Thus operator can set down a credit without registering the same on the computing mechanism, and may set down a total in the some manner. Obviously, therefore, provide an improved machine in which addi-.

tion, subtraction. multiplication and division andother problems may be carried on n a new and improved manner. I also make provision, explained, for listing, and for using the listing mechanism without using the computing mechanism, and vice versa.

All of this iso'f particular advantage, and so far as I know, this is the first time that listing has been carried on in a machine of this particular character.
