CASH REGISTER, INDICATOR, AND RECORDER.

SPECIFICATION forming part of Letters Patent No. 479,720, dated July 26, 1892.

Application filed February 26, 1892. Serial No. 422,881. (No model.)

To all whom it may concern:

Be it known that I, JOHN PFEIFER, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash Registers and Indicators, of which the following is a description, reference being had to the accompanying drawings, forming part of this specification.

The object of my invention is to produce a simple, cheap, and efficient machine of this class; and its novelty consists in new combinations, constructions, and modes of operation, as will be herein set forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of my improved machine with the upper part of the casing removed, the in dicators at O, and the hand-lever in its upper position. Fig. 2 is a front elevation of the machine with all of the casing and the registering mechanism removed, with one key moved to make an indication, and with the hand-lever in its lower position; Fig. 3, a vertical section of the machine on the line 3 3 of Fig. 2 with all the indicators at 0 and the hand-lever in its upper position; Fig. 3, an enlarged detail of part of the drawer-releasing and gong-sounding mechanism; Fig. 4, a vertical section 011 the line -.L et of Fig. 1, but with a key operated and the hand-lever in its lower position; Fig. t, a detail side View of one of the keys and its pawls; Fig. 5, a vertical section on the line 5 5 of Figs. 1 and 2 with the hand-lever up; Fig. 6, a vertical section of the upper part of the machine on the line 6 6 of Fig. 1; Fig. 7, a vertical section of the upper part of the machine on the line 7 7 of Fig. 1; Fig. 8, a front View of the upper part of the machine, showing the application of a printing attachment; and Fig. 0 a vertical section on the line 9 9 of Fig. 8.

The same letters of reference are used to indicate identical parts in all the figures.

The indicator-Wheels A are loosely mounted on a shaft B in the upper part of the machine. They are four in number in this instance, representing, respectively, units of cents, tens of cents, units of dollars, and tens of dollars, and each bearing upon its face a cipher and the nine digits. Fast upon or rigid with each of these wheels is a pinion C, which meshes with a gear-toothed sector D, loosely mounted upon a shaft E, Figs. 3 and 4, there being four sectors, one for each wheel. Integral with or rigidly secured to each sector is a pendent curved arm F, extending nearly to the bottom of the machine. Mounted in the framework at the front of the machine are four inclined guide-rods G, one substantially in line with each of the arms F and sectors E. Upon these rods G slide the operating keys or handles H, one upon each rod. Each of these keys or handles consists of a suitable body portion embracing the rod and carrying friction-rollers bearing thereon, a forwardlyprojecting finger-piece, and a rearwardlyprojecting arm I. This arm I is slotted at its rear end and embraces one of the curved sector-arms F and carries a friction-roller .I, which bears against the rear side of said arm. Under this construction it will be seen that whenever any one of the keys His slid downward upon its forwardly-inclined guide-rod the arm F, which is connected to it, will be gradually drawn forward and the sector E moved upward and rearward. This will cause the indicator-wheel A, which is geared to the sector, to be turned forward and its numbers will, successivelyand in order pass the reading point or window in the casing of the machine. As seen in Fig. 1, the forward-inclined side of the casing has four slots or spaces, between the plates of which it is composed, through which slots or spaces the shanks of the keys II pass and have their play. Beside each of these slots is placed an index H, representing the numbers to be indicated and registered by the adjacent key on the right, and each key carries a laterally-projecting pointer K, arranged to move over its index. The adjustment of the parts is such that when any key is pulled downward until its pointer stands opposite a given number upon its index the arm F, connected to that key, will be drawn forward just far enough to cause its sector to turn the corresponding indicator to position to expose such number at the readingopening in the casing of the machine.

Beside each of the guide-rods G, parallel therewith and extending the full length thereof, is a ratchet-bar L, having the teeth upon its upper and lower sides facing in opposite directions, as seen in Fig. 4:. Each of these bars has its opposite ends bent to the right at right angles to the body of the bar, and by these bent ends it is hung upon the adjacent guide-rod G, the latter passing through holes in the ends of the bar, as seen in Fig. 2. The ratchet-bar is thus free to swing up and down upon and parallel with its supporting guiderod G. The upper end of each ratchet-bar is not only bent to the right, but is widened or extended upward, as seen in the case of the second bar in Fig. 2 and also in Fig. 7, to form a bell-crank plate M, with the rod G as its pivot. It results from this that when the upper end of the plate M is moved to the left the body of the ratchet-bar will be thrown downward, and vice versa. A horizontal bar N, Fig. 2, extends across the machine at the upper ends of the rods G and bars L and the upper end of each bell-crank plate M is pivoted to it. \Vhen the bar N is moved to the left, therefore, all of the ratchet-bars will be thrown downward, and when it is moved to the right they will be lifted. A spiral spring 0, Fig. 1, connected at one end to the framework and at its other to the bar N, pulls the bar to the right and yieldingly holds all of the ratchet-bars in their upper position.

Upon the left-hand side of the bodyof each of the keys H are pivoted two pawls P and P, Fig. 4, the former co-operating with the teeth upon the upper side of the bar and the latter with the teeth upon its lower side. These two pawls are connected by a spring Q, tending to press them into engagement with the ratchets; but stop-pins B, Fig. 4, upon the side of the body of the key limit the movement of the pawls under the stress of the spring, so that when the ratchet-bar is thrown downward to its full limit of movement the upper pawl P will be entirely freed from the upper ratchet, and when it is thrown upward to its limit of movement the pawl'P willbe entirely freed from the lower ratchet. In Fig. 4 both pawls are shown in engagement with the ratchet-bar, which will be hereinafter explained.

lVhen the bar N is held to the light by its spring 0 and the ratchet-bars L are all in their upper positions, the keys H are free to be pulled downward, their pawls P being free from the lower ratchets and their pawls P slipping over the teeth of the upper ratchets; but the engagement of the pawls P with the upper ratchets will prevent any backward movement of the keys. lVhen, therefore, any key is pulled downward until its pointer stands opposite a given number upon its index, that number willbe indicated by the corresponding wheel A, and the key will be caught and held at that point when the finger of the operator is removed from it and the number on the indicator will remain exposed to view. Vhcn the ratchet-bar is thrown downward to its limit of movement, by moving the barN to the left to its limit of move ment the upper ratchet will be disengaged from the pawl P and the lower ratchet engaged with the pawl P. The key is thereupon free to be moved upward to normal position, but cannot be pulled farther down ward. When started back to normalposition, too, the engagement of the pawl P with the successive teeth of the lower ratchet will prevent retrograde movement at any point, so that the key must be returned entirely to normal position before it can be again operated.

Each of the sectors D has connected to it the forward end of a spring S, Fig. 3, whose rear end is secured to the framework. This spring tends to pull the lower end of the sector and its arm F rearward and yieldingly hold them in the position shown in Fig. 3, with the indicator-wheel standing at O. The strain of these springs, exerted upon the keys H through the arms F and I, will cause the keys to be slid upward upon their rods G to normal position whenever their pawls P are disengaged froin the ratchets upon the upper sides of the bars L. \Vhen, therefore, one or more keys have been pulled downward and caught, as in the case of the second key in Fig. 2,to make an indication and registration, and the barN is then moved to the left to its limit of movement, and the ratchet-bars L thereby thrown downward, all of such keys will be released and the springs S will restore them to normal position and reset the indicator-wheels to O.

The bar N is moved to the left to release the operated keys in the manner and by the means to be now described.

Fast upon the right-hand end of the shaft E, just within the side frame of the machine, is a gear-wheel T, Fig. 5, (or it may be simply a gear-toothed sector,) while fast upon the end of the shaft outside the frame is a handlever U. The gear T meshes with a vertical rack-bar V, mounted to slide up and down in suitable guides. When the end of the handlever is thrown down, the rack-bar is moved downward, and vice versa. Plvoted at its lower end to the framework is an arm W, Figs. 1, 2, and 5, having an outwardlyand upwardly curved extension X, Fig. 5, whose upper end bears against the right-hand end of the bar N, heretofore described, as seen in Figs. 1 and 2. hen the upper end of the arm 7 is thrown to the left, therefore, the bar N will be forced in that direction and the ratchet-bars L all thrown downward. Pivoted in a slot in the upper end of the arm W is a trip Y, whose nose projects to the right beyond the face of the bar, as seen in Figs. 1 and 2, and to whose opposite end is connected a spring Z, tending to pull that end of the trip downward and hold the trip in the position shown in Fig. 1. When the parts are in the position shown in Figs. 1 and 5, the nose of the trip projects beneath the lower end of the rack-bar V. The arm W has also upon its outer side at its upper end a beveled projection Z, which stands below the end of the rack-bar V. Vhen the bar is moved downward by the depression of the hand-lever, its lower end, riding over the beveled projection Z on the arm IV, forces said arm, and consequently the bar N, slightly toward the left. This movement of the bar N is not sufficient to throw the ratchet-bars L far enough downward to disengage their upper ratchets from the pawls P and release the keys; but it is sufficient to move their lower ratchets into engagement with the pawls P, the result being thatboth pawls of each key are now engaged with its ratchet-bar, as seen in Fig. 4t, and the key is positively locked from movement in either direction. The lower end of the rack-bar as it has moved downward has depressed the nose of the trip Y and flipped up its opposite end, and the trip remains in this position until a hole in the rack-bar at A, Fig. 5, comes opposite the nose of the trip, whereupon the latter flips into it and the trip assumes the position shown in Fig. 2. At the beginning of the return upward movement of the bar the nose of the trip is carried upward by the hole A in the bar as far as the play of the trip in its hearings will permit, and then as the nose is forced out of thehole in the bar and bears against the face of the bar below said hole the arm \V and the bar N will be forced still farther to the left, depressing all of the ratchet-bars L still further and releasing the operated keys, which will thereupon be restored to normal position in the manner before explained. \Vhen the rack-bar V has been lifted to the position shown in Figs. 1 and 5 and its lower end carried above the-beveled projection Z and nose of the trip, the arm \V will be released and the bar N will be thrown to the right again by the spring 0, thereby lifting all the ratchet-bars L, disengaging their lower ratchets from the pawls P, and engaging their upper ratchets with the pawls P, ready for new operations of the keys.

Supported at its opposite ends byarms D, projecting from sleeves O,loose uponthe shaft B, is a screen-plate B, Figs. 1 and 2, extending across the series of indicator-wheels. Fast upon the right-hand end of the right-hand sleeve 0 is a pendent arm E, which co-operates with an arm F, fast on the gear T, Fig. 5. When the hand-lever is thrown down to its lowest position, the arm F strikes the arm E and throws the screen-plate up to the position shown in Fig. 2, thereby exposing the numbers on the indicator-wheels to view. WVhen the hand-lever is thrown upward and the arm F is carried away from the arm E, the screen is lowered by gravity in front of the indicatorwheels to hide their numbers while the wheels are returning to 0 and being moved to the new indication. Upon the screen I3, I place the words No Sale, so that whenever the screen is exposed to view and the wheels hidden those words will indicate that .the machine has not been properly orcompletely operated. Instead of the words No Sale, the screen might bear the words Sale not Registered, This Should not Show, or like words to call the attention of the customer to any attempted improper manipulation of the machine by the clerk.

A double-toothed pawl G, Fig. 5, co-operates with the gear T and pins I thereon and with a spring-catch J in the usual manner to compel a full stroke of the leverUin each direction.

The mode of operation of this much of my machine may be described as follows: In the normal position of the partsthat is, at the end of one operation and preceding the next-- the keys H stand in the various positions to which they havebeen moved at the preceding operation, with the corresponding numbers upon the indicator-wheels exposed to view. The pawls P of the keys are engaged with the upper ratchets of the bars L, the hand-lever U is down, and the parts stand in the position shown in Figs. 2 and 4. The first step in the new operation of the machine is to throw up the hand-lever U to its uppermost position. This will lower the screen-plate B to a position in front of the indicators and move the bar N to the left, thereby releasing all of the operated keys, which will then be restored to their uppermost position and the indicatorwheels turned to 0. Then the proper keys are pulled downward untiltheirpointers stand opposite the numbers which are to be indicated and registered. Then the hand-lever U is thrown down again, lifting the screen B to expose the new indication and moving the bar N far enough to the left to engage the ratchet-bar L with both pawls of each key, and thereby positively lock both the operated and unoperated keys from any movement.

It will be understood that the co-operation of the pawls P of the keys with the upper ratchets of the bars L is so far independent of the co-operation of the pawls P with the lower ratchets of those bars that the one set of ratchets and pawls may be employed without the other. Thus if the bars L had no ratchets upon their inner sides and the keys carried no pawls P the pawls P would still co-operate with the upper ratchets of the bars to hold the operated keys at the points to which they are moved until released by the upward movement of the hand-lever. In such case the beveled projection Z upon the arm IV would be dispensed with and the nose of the trip Y alone engage the rack-bar V. lVithout the pawls P and lower ratchets on the bars L and the projection Z, co-operating with the rack-bar V, the keys would not be locked from movement during the downward stroke of the hand-lever, as they now are; but such locking operation, though desirable, is not essential to the practical use of the machine. It will also be understood that while I have shown the pawls carried by the keys and co-operating with the ratchet-bars as being pivoted to the keys and spring-pressed into engagement with the ratchets, yet this feature of my invention may not be evaded by direction, or the bearings of the keys in their guides might be made slightly yielding for the same purpose.

In addition to locking the keys after the hand-lever is started downward I have provided means for locking said lever against downward movement until one or more of the keys H has been moved to make an indication. Upon a rock-shaft K, extending across the machine at the rear of the sectors D, Figs. 3, 4, 6, and 7, are fastened four arms L, one extending forward beside each of the sectors. Each of the arms L has a notch in its upper side into which fits a pin H upon the adjacent sector D when the latter is in normal position. When any one of the keys II is pulled downward and the corresponding sector rocked upon its axis, its pin M will be carried out of the notch in the arm L and the arm will be pressed downward and the shaft K rocked forward against the resistance of a spring N, Fig. 4, connected at its lower end to the framework and at its upper end to a screw upon the rear side of the shaft. Fast upon the shaft K, near its left-hand end, Figs. 6 and 7, is an arm 0, projecting forward and arranged to co-operate with a shoulder Q upon a sleeve Q fast upon the shaft E, which latter shaft, it will be remembered, has fast upon its opposite end the hand-lever U. When the sectors D are all in their normal position, with the indicator-wheels standing at O, (as they always are when the hand-lever is in its upper position) and the arms L upon the rock-shaft K are in their highest position, with their notches engaged with the pins M, the front end of the arm 0 stands immediately behind the shoulder Q, so that the shaft E cannot be oscillated in the direction of the arrow, Figs. 6 and 7, and the hand-lever U is locked from downward movement. When, however, any sector is oscillated by the operation of a key its pin, M will press down the adjacent arm L and rock the shaft K and throw the arm 0 out of the path of the shoulder Q, and thereby unlock the hand-lever, as will be readily understood.

I will next describe the means I have provided for preventing downward movement of 3, 4, and 7, are fastened four forwardly-extendin arms S one beside each of the arms F of the sectors D. The upper sides of these arms are notched and pins T upon the sides of the arms F eo-operate with the notches. Fast upon the left-hand end of the shaft R, Figs. 1, 3, 6, and 7, is an upwardly-extending arm V, to which is connected the forward end of a spring WV, secured at its rear end to the framework and tending to pull the arm V rearward and throw the arms S upward. Resting upon the upper end of the arm V is an arm X, loosely hung upon the shaft K, above and extending forward over the sleeve Q which is fast upon the shaft E. The forward end of the arm is hooked and arranged to cooperate with a shoulder Y upon the sleeve Q Fig. 6. When the pins T on the arms F all rest in notches in the arms S, the

spring \V holds the arm V and the arms S in their highest positions, and the upper end of the arm V then holds the hooked arm X up out of the path of the lug Y on the sleeve Q as in Figs. 6 and 7; but when any sectorarm F is moved to such a position that its pin T rests upon the top of the tooth between two of the notches in its co-operating arm S',said arm and all of the arms S will be slightly depressed, as will also the arm V, and the hooked arm X, resting on the latter, will be lowered into the path of the lug Y and the shaft E and lever U be thereby locked from movement. Now whenever any key is pulled downward and released at a point between two numbers upon its index, (instead of being moved to a point exactly opposite a number thereof,) the pin T on the sector-arm which is connected with that key will be left resting upon the top of one of the teethin its co-operating arm S, instead of resting in a notch thereof, the arms S and V will be depressed, and the hooked arm X will lock the shaft and lever from movementin the manner above described. It will thus be seen that,in order to operate the lever U after it has been thrown upward to release the previously-operated keys and lower the screen-plate to hide the indicator-wheels it is not only necessary to pull down some one of the operating-keys to make an indication, and thereby throw down the arms L and rock the shaft K to carry the arm 0 out of the path of the shoulder Q on the sleeve Q, as before described, but it is also necessary that the operated key shall be moved to and released at a point opposite some number upon its index, so that such number will be properly indicated when the lever is thrown down and the screen lifted.

The lower sides of the pins T are preferably beveled to an edge, as shown, and their co operation with the upwardly pressed notched arms S aids the operator in moving the key to and releasing it at the proper point, for if the key be released at a point approximately opposite a number the upward pressure of the arms S will force the operated sector-arm F slightly one way or the other to per- ICC mit its pin T to fit in the bottom of the notch with which it may be engaged.

I have provided still another lock for the purpose of preventing the lever U being moved upward to its full limit of stroke until the operated key or keys have been fully restored to their upper positions and the indicators turned to 0. It will be remembered that the bar N is moved to the left by the trip Y and the arm V to release the operated keys at the beginning of the upward stroke of the lever U and rack V and that the keys and sectors are then restored to normal position by the springs S, Figs. 3 and at. Now it is not until the keys and sectors reach normal posi tion that the pins Iv on the latter are brought into position for the notches in the arms L to engage them, and it is not until these notches are engaged with the pins M that the spring N can rock the shaft K and lift the arm 0, Figs. 6 and 7, into the path of the shoulder Q on the sleeve Q As long, therefore, as any one of the keys is displaced from its uppermost position and the pin M on the co-operating sector remains outof the notch in its arm L the arm 0 will be held out of the path of the shoulder Q. .In such case, therefore, when the lever U was moved to its uppermost position and the shoulder Q carried in front of the end of the arm 0, thelatter would not catch behind the shoulder and the shaft E and lever would remain unlocked and the lever could bethrown down again without first operating any key. It is intended that all of the operated keys shall be immediately restored to their uppermost positions when released at the beginning of the upward movement of the lever Y and rack V; but it is to guard against any accidental failure of them to do so that the lock to be now de scribed is provided. It consists of an arm Z, Fig. '7, loosely hung upon the shaft K beside the arm 0' and arranged to co-operate with a shoulder Z upon the sleeve Q This arm rests upon a pin or lug Z projecting from the side of the arm 0', by which lug its front end is held above thepa h of the shoulder Z when the arm 0' is in its uppermost position, as shown in Fig. 7. It will be remembered that when any key is pulled downward the arm 0 is lowered out of the path of the lug to unlock the shaft E and lever U. This lowering of the arm 0, whose lug Z supports the arm Z will permit the front end of the latter arm to drop upon the top of the shoulder Z \Vhen the lever U is now depressed and the shaftEturned forward in the direction of the arrow, the shoulder Z will be carried from under the arm Z and the latter will drop behind it. The arm Z will remain in this position until the arm 0' is again raised by the return of all the keys to upper position in the manner heretofore described, so that until all of the keys are so returned and the arm 0 so lifted the arm Z will remain in the path of return of the shoulder Z and prevent a complete backward movement of the shaft E and upward stroke of the lever U. If, therefore, any key should fail to entirely reach normal position when released at the beginning of the upward stroke of the lever and the operator should fail to notice it, he will [ind the lever locked from full upward stroke, and since when once started upward itcannot move backward again until given a full upward stroke (because of the double-toothed pawl G, which co-operates with the gear T, Fig. 5) it will be locked from movement in either direction until the key or keys which have failed to return to normal position are moved to such position.

The registering-wheels A A A*, and A Fig. 1, are loosely mounted upon a shaft B extending across the machine in front of the sectors D and journaled at its opposite ends in the side frames. The hubs C of these wheels on their right sides have clutch-teeth formed on their ends and co-operate with clutch-pinions D feathered upon the shaft 13 These pinions mesh with the respective sectors D and coiled springs E conlined between their right-hand ends, and collars F fast on the shaft B yieldingly press their clutch ends into engagement with the hubs of the registering-wheels. \Vhen thekeys are pulled downward and the sectors moved upward, the pinions carry the registering-wheels around with them to effect a registration of the amount indicated; but as the keys are restored to normal position and the segments moved upward the registering-wheels remain stationary, being held from backward movement by the pawls (not shown) engaging ratchets secured to their left-hand sides. Suitable transfer mechanism, which need not be described in detail, is interposed between theregistering-wheels to cause the revolution of each wheel to turn the next higher wheel one number. At the left of the fourth registering-wheel A are two additional registering-wheels A and A representing, respectively, hundredsand thousands of dollars and actuated by transfer mechanism from the wheel A Combined with the last wheel A is a locking-lever H Figs. (5 and 7, which is pivoted to the framework at I and has a hooked rear end arranged to co-operate with the shoulder Z upon the sleeve Q Fig. 7, heretofore described. The front end of the lever 11 bears upon the hub of the wheel A its rear end being pulled upward by a spring J and said hub has upon it a projection or cam K Fig. 6. When the wheel A has made nine-tenths of a revolution and brought its number 0 to the reading-point, the cam K upon its hub rides under and lifts thefront end of the lever I1 and throws its hooked rear end down against the shoulder Z Fig. 7. When the lever U is pulled down and the shaft .E and sleeve Q rocked forward, the shoulder Z 'is carried from under the rear end of the lever 11 and the hook of the latter catches behind the shoulder. hen it is attempted to throw the lever U upward again,

it will be arrested by the engagement of the shoulder Z with the hook of the lever H before it reaches its limit of stroke, and as it cannot be moved downward until it completes its upward stroke it will be locked from movement in either direction. The operated keys having been released and restored to normal position at the beginning of such upward movement of the lever. all of the keys are held locked from movement by the engagement. of their pawls P with the lower ratchets on the bars L, so that the whole mach ne is locked from further operation. In this manner, when the highest registeringwheel has been turned to its highest number the machine becomes automatically locked.

The right-hand end of the shaft B projects beyond the framework, Fig. 1, andis squared to receive a key, by which the shaft may be turned to reset all of the registering-wheels to 0, suitable resetting devices being interposed between the shaft and registeringwheels for that purpose. The turningof the wheel A to O carries the cam K from under the lever H and the spring J pulls up the rear end of the latter and disengages its hook from the shoulder Z The leverUcan then complete its upward stroke and the operations of the machine be resumed.

The framework of the machine shown in the drawings is intended to be set on the usual base containing a drawer-compartment and money-drawer, and in Fig. 3 are shown the drawer-bolt and the means for actuating it to unlock the drawer. A lever L pivoted between its ends in the bracket M has its rear end passed through a slot in the vertically-guided drawerbolt N whose lower end extends down into the drawer-compartment into position to engage the drawer or a catch thereon. A gong O is mounted upon a standard P above the front end of the lever L and a spring R bearing against the underside of the lever, yieldingly holds its front end up and its rear end down. Ver near its middle is the lower end of a link S which extends upward to the shaft E, being forked at its upper end to embrace said shaft. Fast upon the shaft E, beside the link S is a forwardly-projecting arm T to which is pivoted a plate U Fig. 3 This plate is yieldingly held in the position shown by a spring U and carries upon one side of its lower rear end a cam-lug V arranged to cooperate with a lug W upon the side of the link S The rear end of the plate U is held from upward movement by contact with the projecting face of the arm T at U; but it can be moved in the opposite direction against the pressure of the spring U W'hen the le- WVhen the Pivoted to the lelug V passes to the rear of the lug V the spring R throws up the link S and front end of the lever L and causes the latter to strike and sound the gong. lVhen the lever U is thrown up again and the plate U moved forward, the front end of the lug V engages the beveled rear side of the lug V and passes under the latter, the plate U swinging upon its pivot against the pressure of its spring to permit it to do so. hen the lug V has passed to the front of the lug W the plate U resumes its normal position. (Shown in Fig. 3.)

Under the construction shown in the first seven figures of the drawings and thus far described my machine is designed simply to indicate and register the amounts of the sales; but I can also readily combine with it a printing attachment, by which the amount of each sale may be printed upon a check or ticket to be delivered to the customer, and also upon a permanent record-strip, if desired. In Figs. 8 and 9 I have shown such a printing attachment applied to the machine. As seen in Fig. 8, the indicator-wheels A, instead of being loosely mounted on the shaft B, as before described, are, with the exception of the one on the right, secured upon sleeves B concentrically mounted upon the shaft B and free to turn independently of each other. The wheel A on the extreme right and its driving-pinion O are fast on the shaft B, (though they, too, might be secured upon a fourth sleeve within the other three,) while the other wheels A and their driving-pinions are fast upon the righthand ends of the respective sleeves 13 Fast upon the left-hand ends of said sleeves are three type-wh eels C the fourth type-wheel on the left being fast on the shaft B, so as to turn with the indicator-wheel A on the right. The second type-wheel from the left turns with the second indicator-wheel from the right, and the third and fourth type-wheels from the left turn, respectively, with the third and fourth indicator-wheels from the right. The left-hand type-wheel represents units of cents and turns with the units-of-cents-indicator wheel, and the second, third, and fourth typewheels represent tens of cents and units and tens of dollars, respectively, and turn with the corresponding indicator-wheels. The relative positions of the type-wheels and indicator-wheels upon their respective sleeves and upon the shaft B are such that when any number upon an indicator-wheel is brought to the reading-point the same number upon its corresponding type-wheel will be brought to the printing-point.

Immediately beneath the type-wheels is an impression-platen D carried upon the front end of an arm E Fig. 9, pivotally supported at F Fast upon the shaftE beneath the arm F. is acam G which,when the lever U is thrown downward and the shaft E rocked forward, engages the under side of the arm E and forces the platen D against the type-wheels to effect the printing. The types upon the wheels C may have sharp faces, so as to indent their figures upon the record strip or check interposed between them and the platen, or an inkingribbon maybe passed between the type-wheels to print the typenumbers upon the check or strip. In Fig. 8 I have shown two inking-ribbon spools H arranged upon the opposite sides of the setof type-wheels and supported upon a plate 1 attached to the framework and having an opening in it immediately above the platen for the passage of the latter, as seen in Fig. 9. \Vhere loose checks are to be printed, this plate may serve as a guide and support for them as they are inserted beneath the typewheels. I have shown no means for turning the spools II to wind the ribbon from one onto the other; but this may be done in any convenient way, as by a suitable connection with the platen D or shaft E. So I have not shown the permanent record-strip nor the means for supporting the same and feeding it beneath the type-wheels; but as there are many well-known methods of doing this an illustration and a description of any particular method are not deemed necessary.

It will be understood that where a permanent record-strip is employed in connection with the type-wheels it may constitute the sole record of the sales made, and the registering-wheels A A &c., be dispensed with, if desired. So the type-wheels may be employed without the indicator-wheels, if desired, and, instead of being secured directly upon the sleeves B and shaft B, they may be independently mounted and be geared to said sleeves an d shaft.
