Specification of Letters Patent.

Patented Apr. 9, 1918.

To all whom it may concern:

Be it known that l, EDWARD J. Von Pnrx, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certa'n new and useful Improvements in Printing Mechanism, of which I declare the following to be a full, clear, and exact description.

This invention relates to improvements in accounting machines, and has particular reference to improvements in the printing mechanism thereof.

A main object of the invention is to provide a device which may be embodied in cash registers and other forms of accounting machines having printing mechanisms whereby, in addition to performing their usual functions, such machines may be made to serve satisfactorily as check printers or check protectors.

A number of different styles of such machines are now in general use arranged to print amounts on inserted cheeks, drafts and similar papers, one object being to enforce a record of the amounts in the record retaining devices of the machines as an incident to the printing operation, and another to make it more difficult to raise the amount for which the paper is drawn. This arrangement gives satisfactory protection as far as the compulsory record is concerned, but does notgive a full measure of protection in the way of preventing f audulent alterations of the amounts printed, as said amounts are usually printed in figures, and it requires the addition or alteration of but one or two figures to make such a fraudulent change. It apparent, of course, that increasing the number of ch racters wiich must be altered vill increase the difficulty of making such alterations without detection. This "an probably be best accomplished by printing the full words representing the different denominational values, instead of representing the values by figures and decimal points.

However, the mere substitution of word printing type for the usual figure or digit type, does not accomplish all that is necessary to produce a satisfactory mechanism. This is because of the construction of the type carriers and their operating mechanism. The type carrier in general use is ar-- type, the protection is, as before stated, in-' I creased materially, but there remains to be overcome the obstacle which has, as far as applicant is aware, prevented prior satisfactory application of word printing type carriers to machines of the differential type just mentioned. This obstacle is presented by the fact that the mere substitution of words for digits does not provide for satisfactorily printing the words representing amounts between 10 and 20, 2'. c. eleven, twelve and the teens thirteen to nine teen inclusive in both the dollars and cents orders. For example, such type woulc print from the units and tens of cents carriers the words Ten Five cents, instead of the decimal points and digits .15, while, of course, there should be printed Fifteen cents. This invention consists mainly in the means by which the obstacle just mentioned is ove come.

In the aceompanyin vention is shown appli such as is fully illustra United States Letters latent No. 703,639, granted July 1, 1902 and No. 75%.019, granted March 8, 1904;, to Thomas Carroll. However, as has already been stated, the invention is not limited in its application to any one particular kind of machine, but is capable of application in v -rious modifications to accounting machines in general. In fact, as will appear clearly after the construction is fully understood, the idea is g drawings, the ine to cash register C ted and described in capable of embodiment in structurally separate check printing or protecting devices, such as the ordinary hand operated stamps now in general use in banks and business houses.

It will also be aoparent after the inveu tion is clearly understood, that while the improvement is shown as applied to rotatable type carriers, it is not limited to such an embodiment, but can be applied with equal facility, to. indicators .or similar devices which it may be desirable to first differentially position and then give an additional degree of movement as an incident to further operation of the mechanism comprising such devices.

\Vith the above and Fig. 3 is a chart showing the arrangement of the type on the type carriers.

Fig. 4 is a group of details showing the type carriers in right elevation.

Fig. 5 is a plan view of the printing mechanism. Certain of the parts have been omitted and others broken away, the object being to show to the best advantage the parts directly involved in the invention.

Fig. 6 shows in section certain features of the control for the type carrier operating mechanism. 4

Fig. 7 is a detail of that part of the controlling mechanism shown in Fig. 6 which is designed to control the units and tens of cents type carrier operating mechanism.

Fig. 8 shows in detail the construction of one of the lower order type carriers, the

type being omitted from the periphery for the sake of clearness.

Fig. 9 shows how the amounts are printed on checks by the improved machine.

The machine of the Carroll Patent No. 754,049, to which the invention is shown applied, is one of the ones mentioned above as having ten division type carriers and key controlled differential mechanism for operating them. In applying the invention thereto, type carriers of approximately twice the circumference shown therein have been used andthe width of the carriers has also been increased. Raised word printing type are arranged about the periphery of the carriers and are of about the same height as the digit type of ordinary form which they replace. The increase in circumference is to provide for additional printing spaces on the four lower ordercarriers. In the case of the two higher order carriers, the ones for incidental objects in view, the invention consists 1n certain novel. features of construction and combinations hundreds and thousands of dollars, no change has been made except increasing their circumferences to make them conform in size to the lower order carriers, and, of course, the substitution of word printing type for the digit type.

The tens of cents and tens of dollars carriers have the same general-arrangement of type as the thousands and hundreds of dollars carriers,-except that they are provided with one additional printing face, while the units of cents and units of dollars type carriers, in addition to the words substituted for the usual digits, have alternating therewith the words Eleven, Twelve and so on, and after each of the words on the units carriers is the words Dollars or Cents to designate the denominational values of words preceding in the printing line. The arrangement of the type on all of the carriers is fully shown by the chart in Fig. 3. j The improvement consists in the mechanism whereby on a registration involving the printing of amounts from eleven to nineteen inclusive, either dollars or cents, the type carriers will first be positioned in the usual way by the differential mechanism, and the units and tens carriers on which such an amount has been set up will then be given a movement beyond that imparted by the differential mechanism. This extra movement is for convenience usually spoken of herein as a half step of movement because its extent is about half that of a step of movement imparted by the differential mech anism. The additional movement of the carriers will carry away from the printing line the word on the tens carrier which was just positioned there by the difierential mechanism and position inplace thereof type on the additional printing face above mentioned arranged to print a line of dashes.

-At the same time there will be substituted for the words set up on the units type carriers, the adjacent words which properly represent the value registered. For example: If a registration involves the operation of the ten and live cents keys, the units and tens of cents type carriers will be positioned by their differential devices to print the words Ten Five cents. Just before the impression is taken, devices driven independently of the din erential mechanism, but controlled thereby, give each of the two type carriers the additional or half step of movement. This carries the word Ten away from the printing line and'presents in place thereof the. adjacentprinting face which, as before stated, is provided with type to print a line of dashes. The half step of movement of the cents carriers carries the words Five cents away from the printing line, and substitutes therefor the adjacent words Fifteen cents. The impression then taken will be --Fifteen cents.

Operating mechanism.

The illustrative machine is, as is well known, of the two motion type; that is, one in which entries are made by first depressing the proper keys on the ke board and then turning the operating handle. Such a machine can have any number of banks, depending upon the registering capacity desired. The invention has been shown as designed for a machine having six banks, one of which is shown in detail in Fig. 1. The remaining banks have been omitted for the sake of simplification as they are mere duplicates of the one shown. Each of the banks has a vertical row of selectively depressible keys 2O ranging in value from one at the bottom to 9 at the top. The keys are held in depressed position when operated until near the end of an operation of the main operating mechanism by a detent 21, (Fig. 1) and a retaining bar 22, with one end of the depressed key projecting into the path of a trip 23 carried by an operating member 24.

The operating handle 25 (Fig. 2) has at tached thereto a pinion 26, meshing with a large intermediate gear 27 rotatably mounted on a stud shaft 28 in the machine frame. The intermediate gear, in turn, drives gears 81 and 32 attached to the shafts 33 and 34; respectively, which extend across the ma chine. This gearing is so proportioned that two complete rotations of the operating handle will cause the shafts 33 and 34.- to be given one complete rotation.

Dz'fierential mechanism.

Running transversely through the machine is a rock shaft 35 (Fig. 1). Attached to'this rock shaft is an arm 87 connected by a link 38 to an arm 39, fastened to the driving shaft Wh n the shaft- ?A is rotated, the arm 39 is, of course, carried. with it, thereby, through the link 38 and arm 37, rocking the shaft 35 throu h an arc of about 90 degrees, first clockwise and then anti-clockwise, Fig. 1. During the anti-clockwise movement, a plunger 41 carried by the operating member 2% engages a lug i2 on a plate 43 attached to a plate 36 fast on the shaft and through the connection so formed the operating member 2 1': is carried upward during the clockwise oscillation of the plate 36 until the trip 23, which is operatively connected to the plunger %1, strikes the inner end of the depressed key and causes the plunger to be disengaged from the lug d2, thereby disabling the connection between the operating member 24 and the plate 36. As the plunger 4-1 is disengaged from the lug 42 it is projected into the one of the notches L4 corresponding to the key so as to hold the operating member in its adjusted position The operating member 24 is formed with a rack in mesh at all times with an intermediate gear 45, and the differential adjustment of the operating member is transmitted through said gear and a pinion 451 to an indicator d6.

Type carrier operating mechanism.

Extending across the machine is a shaft 47 and a series of nested sleeves 4L8 concentric to and supported by said shaft. Attached to the shaft and each of the sleeves is an arm 51 having a curved slot 52 cooperating with a stud on the operating member 2st. Through this connection the differential movement of the operating members 2a is transmitted to the shaft at? and sleeves &8. At their right ends this shaft and sleeves each carries a rack plate 56, Figs. 2 and 5. Teeth 5st carried by these plates are at all times in engagement with gears 57 attached to the inner ends of a shaft 59 and sleeves 60. Secured to the other ends of said shaft and sleeves are type carriers 58. The mechanism just described is so proportioned that for each step of movement permitted to an operating member 24 by the keys 20 the corresponding type carrier i turned one division, thereby positioning, opposite a platen 61, the type corresponding to the key 20 which was depressed at the beginning of the operation.

All of the mechanism described so far is more fully shown and explained in the Carroll patent above mentioned, and reference may be had to said Patent No. 754,044), if more detailed information is desired.

As hereinbefore stated, the units and tens type carriers of both the dollars and cents denominations are on certain registration given a half step of movement by devices driven independently of, but controlled by the differential mechanism. The means whereby this is accomplished comprises disks 62 attached to the sides of the type carriers, as best shown in Fig. l. The disks for the units of cents and units of dollars are each provided with 10 lugs 63, while the disks attached to the tens of cents and tens of dollars carriers each have but a single lug 631. No lugs are provided for the hundreds and thousands of dollars carriers because they are positioned entirely by the differential mechanism, that i to say, they are never given the half step of movement which is at certain times imparted to the four lower order carriers.

Arranged to act against the lugs 63 and 631 at the proper times are slides 64, Figs. 2 and 5, one for each of the four lower order carriers. These slides are held against lateral displacement by a slotted guide 65 supported by the printer frames, and are pivoted at their rear ends to arms 66 secured to a rock shaft 67. Fastened to said rock shaft is a short rearwardly extending arm 68, to which is pivoted one end of aI-pitman 69 slotted to encompass the shaft .84 and carrying at its upper end a roller 71 projecting into a cam groove 72 formed in the side of the gear 32. It will be remembered that this gear makes a completerotation on every operation of the machine. The configuration of the cam groove is such, that near the end of the operation of the shaft'34 the shaft 67 is rocked, and the slides 64 are first thrown forward and then returned to the normal positions in which they are shown'in the drawings. It Is during this forward movement, if at all, that these shoes engage the lugs 63 and 631 attached to the type carriers to give the carriers the half step of movement above mentioned. However,

mally prevented by the forward ends of the slides being held up so that during their reciprocation they pass above the lugs 63 and 631, thereby causing the movements of are given the usual reciprocation their ends will engage such lugs 63 and 631 as may happen to be in their paths and rotate the corresponding type carriers. The extent of the reciprocation of the slides 64 is just sufficient to rotate the carriers half the distance that they are rotated by a step of the differential mechanism.

' The devices employed whereby the slides 64 are lowered at certain operations will next be described. The plates 56 (Fig. 2) carrying the racks for positioning the four lower order type carriers have integral therewith racks 81, which are constantly in engagement with gears 82 (Figs. 5 and 6). The left hand one of these gears is attached to a shaft 83 rotatably'mounted in the printer frames. This gear and shaft are driven by the difierential mechanism for the lowest order or units of cents bank. Cone ntric to and supported by the shaft 83 are three sleeves 84, each having attached to its left end one of the gears 82. These gears are driven by the differential mechanism of the tens of cents,

' units of dollars and tens of dollars banks respectively from left to right in the order named.

Fastened to the right hand endof the shaft 83 is a gear 91 meshing with a gear 92 secured to a short shaft 93, journaled at one end in the outsidev printer frame, and

this result is nor at the other in a boss carried by the upper end of a bracket 931 (Fig. 5) attached to said frame. Rigid on the shaft 93 is a second gear 94 (Fig. 6) meshing with a gear 95, rotating on the tens of cents sleeve 84.

Secured'to the gear 95 so as to rotate there- 7 with is a disk 96 having an ear 97, best shown in Fig. 7, which in the normal, or zero position of the units of cents differential mechanismrests under a roller 98 carried by the arm for the tens of cents bank, and holds said arm and its slide 64 in the raised position. The ear 97 is so shaped that if the shaft 83 is rotated even Y a single step by the units of cents difier- 'ential mechanism, the slide 64 will be low 'rier is rotated more thanone step the lug 631 is carried so far that it is out of the path of the end of the slide.

The tens of cents sleeve 84 which, as already indicated, is the one next to the shaft 83, carries at its right end a disk 101 (Figs. 6 and 7) having a notch 102 in its periphery. A single step adjustment of the dimes bank differential mechanism, such as occurs when the machine is operated with the ten cent key depressed, will cause the disk 101 to be rotatedone stepofrom the zero position in which it is shown, bringing the notch 102 under the roller 98 carried by'the arm 75 for the units of cents bank. This allows said arm and the connected slide 64 to be lowered by the corresponding spring 78 so that when the slide is reciprocated its forward end will engage whichever one of the ten lugs 63 carried by the units of cents type carriers happens to be in the path of the slide 64 and rotate the carrier a half step beyond the position to which it was previously adjusted by its differential mechanism. In all positions of the tens of cents differential mechanism other than the one just mentioned, the units slide is held in ineffective position by the periphery of the disk 101.

said disk under the roller 98 and allowing thearm 75 for the units of cents bank and the slide 64 connected thereto to be drawn down to effective position. At the same time, the differential mechanism for the units of cents bank will position its type car ier and rotate the shaft 83, gears 91 and 92, the short shaft 93, the gears 94 and 95 and the disk 96, five steps. At the beginning of this rotation, the ear 97 on the disk 96 is carried from under the roller 98 on the arm 75 for the dimes bank, allowing the arm and corresponding slide 6 1 to be lowered. As the one step of rotation of the tens of dimes carrier has carried the lug 681 into the path of the slide 64, when the slide for that bank is reciprocated said lug. will be engaged and the tens type carrier moved forward a half step. This will bring the space between the words Ten and Twenty, see Fig. 3, to the printing line. This space is arranged to print a series of dashes to fill up the space which would otherwise be left blank. During its reciprocation the slide for the units of cents bank will engage the one of the lugs 68 which was brought into effective position by the five steps of rotation of the units of cents type carrier and give the units carrier a half step of movement, carrying the words Five cents away from the printing line and presenting in place thereofthe adjacent words Fifteen cents.

From the immediately preceding description it'is apparent that if the ten cent key only is pressed, the disk 101 will be rotated the right distance to present its notch 102 to the roller 98 for the units of cents bank, thereby allowing the arm 75 and slide 64 for that bank to be lowered. In such a registration the units of cents type carrier will be at its normal Zero position, in which position it prints the characters Cents but these type are carried away from the printing line in the usual way by the operation of the slide 64. In order to take care of the condition just mentioned; that is. to properly print in the units division when the ten cent key only is operated, the designation for the zero position is repeated at the next half step above on the type carrier so that when the slide (let operates, the half step of movement imparted to the carrier will cause it to print the same character as though the carrier remained undisturbed in its zero position. It is obvious, however. that the lug 63 at. the zero position might be omitted instead of du alica'tin v p I:

the type for the zero position. 7

The mechanism for imparting the half step-of movement to the units and tens of dollars type-carriersis the same as the mecha for thje'units and tens of cents INS-1560111011 of produce like results. There is, therefore, no necessity for repeating the description.

In the foregoing, reference has been made to the fact that the four lower type carriers are capable of a half step of movement independent of the differential mechanism. T he devices by which this independent movement of the carriers is permitted are shown in Fig. 8. Each of these four carriers is hollow and has an internal hub 111, loosely journaled on the shaft 59 or one of the tubes 60 as the case may be. A rib 112 extends between the hub and the outside shell of the carrier. Fastened to the shaft 59 and each of the tubes 60 is a disk 113 having a slot 114 through which extends a stud 115 on the rib 112. A spring 116 is fastened at one end to the stud 115, and at the other end to a stud 117 on the disk 113. This construction causes the type carrier to move in correct relation to the movement of its differential mechanism. but when a slide 64: gives one of these carriers a half step of movement, the carrier is moved against the tension of the spring 116 until the stud 115 is carried to the opposite end of the slot 114 from that at which itis shown. lV hen the slide is drawn rearward to its normal position the spring returns the carrier to normal relation with its differential devices.

baking and impression taking devices.

An inspection of the cam groove 72 formed in the gear 32 on shaft 34; (Fig. 2) will show that after it operates the pitnian 69 to throw the slides 6% forward, it holds the pitman and slides in their operated peel-- tions for some little time. If the slides have been lowered and engage the lugs on the type carriers, the carriers are during this time held in their half step positions of adjustment against the tension of their springs 116. However, regardless of whether or not any of the carriers are at the time being so hold in their half step positions, it is during this period of the operation that the position type are inked and impression taken therefrom.

The ink for the type is supplied by a pad 121 carried by a plate 122 supported at either end so as to have a slight rocking movement by stucs 123 on arms carried by rotatable elements 120. The right hand one of tiese elements is journaled on the shaft 59 while the other rotates about the outer type wheel sleeve 60, see Fig.5". Rigid with the elements 120 are other elements 118- bearing teeth 119. For each of these toothed elements there is provided a pitman 125 (Figs. 2 and 5). These p'itmen have elongated openings at their forward ends surrounding toothed elements 118 andare provided with teeth-12a meshing withthe teeth 1-19. Attheinrear ends the pit-men are slotted to straddle a shaft 126 and-each times.

carries an antifriction roller 127 projecting into a cam groove 128 formed in the sides of gears 129 secured to the shaft 126. The

gears 129 are in mesh with gears 130 se- :34 makes one complete rotation at each operation of the machine and the gears 129 and 130 are rotated to the same extent. The configuration of the cam grooves 128 is such that at near the end of an operation of the machine the pitmen 125 are thrust forward and the teeth 124: acting against the teeth 119 cause the elements 120 to be rotated to bring the ink pad 121 over the platen 61.

, The platen 61 is raised twice during each operation. The first time it presses the ink pad against the type carriers, after which the pad is restored to the normal position in which it is shown in Fig. 2, and the second time it presses the inserted paper against the type to take the impression from the type of the item set up thereon.

The platen 61 is adjustably mounted in a frame 135 arranged to slide vertically in a bracket 136 secured to the machine frame. At each end of the. frame 135 is a stud 139 projecting through a slotin the forward end of one of a pair of levers 137. The levers 137 are pivoted on a rod 138, and at their rear ends carry anti-friction rollers projecting laterally into cam grooves 1411 formed in the sides of gears 1412 secured to a. short shaft 143 journaled in the printer frame. These gears-are, through the gears 132 and 129 rotated once at each operation of the machine. As shown the cam grooves 1&1 are arranged to operate the levers 137 twice at eachrotation of the gears 1&2, raising the platen a corresponding number of As already indicated at the first operation the ink pad is pressed up against the type, and at the next the check or other record material is pressed against the face of the type. 7

Attached to the machine frame is a table 141 to receive the check or other paper on which the amount is to be printed. This table extends the width of the type carriers, and has an opening through which the platen 61 operates. A stop 1 15, which of course may be arranged to be adjustable to different positions, serves as a guide in-placing the paper on the table to insure positioning the paper correctly to effect the printing at the desired point.

Operation.

In describing the mechanism, it has been necessary inc dentally to explain the operation of the devices comprised by the imremn n 1 such a ex nt; w-t r f thought that only a very brief summary of the operation is necessary here. The check or other paper which is to receive the 1mpression is laid upon the table 1-14 with its mechanism controlled by the keys and driven from the operating handle rotates the type carriers 58 in the usual manner to position opposite the platen 61 the words on each representing the different keys pressed. If the amount to be printed does not include any of the numbers 11 to 19 inclusive in either the dollars or cents orders, the impression is simply taken from the positioned type carriers in the usual way. If, however, the amount to be printed does involve the printing of one of such amounts, both the units and tens type carriers of the denominational orders involved are given a half step of movement in addition to the movemechanism and substitutes therefor words.

on said carrier indicating the total value represented by the two keys operated in the units and tens banks. For example, in a fifteen cent registration the differential mechanism would operate the type carriers to position at the printing line the word Ten on the tens type carrier and the words Five cents on the units type carrier. The controlling disks 96 and 101 would incidentally be operated by the difierential mechanism to allow the corresponding slides 64; to be lowered so that when said slides are reciprocated the lugs 631 on the tens type carriers and the-proper lug 63 on' the units carrier would be engaged, thereby rotating the two carriers a half step beyond the positions to which they were adjusted by their differential devices. This substitutes for the word Ten, the type to print the row of dashes, and for the words Five cents the words Fifteen cents. The type are then inked and the impression taken while the auxiliary devices hold the carriers in their newly adjusted positions, and upon the withdrawal of the auxiliary devices, the type-carriers are-returned to'their normal relations to the difierential mechanism. 7 It is to beunderstood that while the incarriers.
