Patented May 26, 1908.

Application filed April 18, 1907. Serial No. 868,863.

T all whom it may concern:

Be it known that l, FRED SALINGER, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Adding-Machine, of which the following is a specification.

The object of my invention is to provide an adding machine that will print the nu1n bers in properly arranged columns, and that may easily and quickly be operated to print the totals of the numbers at any desirable time, and that may be-shifted to bring all of the adding wheels back to starting posi- 5 tion, and that will. visibly indicate to the operator the position of each adding wheel at all't'nnes.

My object is primarily to provide a machine of' 'this kind of simple, durable and inexpensfve construction.

My inventlon consists 1n certain details in the construction, arrangement'and coinbination of the various parts of the device whereby simplicity and durability of con,

struction are provided, and at the same time a machine is produced capable of accomplishing all of the desirable results of the more complicated and expensive machines as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which-;-

Fig. 7 shows a etail plan view, illustrating the shaft of the adding wheels, and the spacing bars thereon for separating the adding -WhG8lS. Fig.- 8 shows an enlarged detail view through a part of the machine frame adjacent to the shaft of the adding wheels, showing some of the adding wheels in se tion, and some in elevation, and illustrating from which numbers are printed, and the dotted lines show the positions of these printing hammers adjacent to the adding wheels from which the totals are taken. Fig. 9 shows a side view illustratin the device for normally locking the shaft of the adding wheels, and. for releasing and turning the said shaft for clearing the adding wheels and returning them to normal position. Fig. 10 shows a rear elevation of the entire machine with part of the paper roller broken away. Fig. 11 shows a detail sectional View illustrating the key bars for printing totals, and the arrangement by which a depression of one of the key bars will cause a movement of all of the )rinting hammers to the right of the key bar epressed, so that the entire-total may be printed'by a single operation. The dotted hnes in this figure show the key bar in the fourth column depressed, and all of the other key bars to the right correspondingly depressed by it. Fig. 12 shows a face view of the three printing wheels to the left of the machine illustrating the position of the periods on the second wheel to indicate decimal points. Fig. 13 shows a detail perspective view of the mechanism for operating the printing hammers, and for shiftlng the earriage'that supports the printing hammers and paper holding devices. Fig. 14 shows a detail view illustrating the mechanism for clearing the adding wheels and returning them to normal position, the pawl being shown in position for permitting the pin on the adding wheel to pass it. Fig. 15 shows a similar view with the pawl in position to engage and stop the pin on the addin wheel. Fig. 16 shows a detail plan view of t e shaft for supporting the said pawls, and also showing a number of pawls in osition on said shaft. Fig. 17 shows a detai lan view illustrating the lever for shifting t 10 ribbon supin the frame is a shaft 11 for supporting the ievers of the printing segments. I have provided one of t ese levers for each column of key bars. The body portion of the lever is indicated by the numeral 12, and normally inclines upwardly at its front end, its rear end bein provided with a segmental printing arm 13, having on its front face a series of cogteeth 14, and having on its outer face a series of type 15, the upper type having the numeral 0 the next the numeral l and so on. ,The rear end of the lever 12 is nor mally held downwardly by means of the spring 1.6.; Obviously, if the forward end of t e lever is moved down a short distance, the second type from the top of the segmental bar 13 will be moved to printing position, and if moved down to its lower limit, the last type of the segmental bar 13 will be moved to printing position. I have provided for operating these levers the required distance by means of a series of keybars for each of the levers 12. These key bars are each indicated by the numeral 17 and are slidingly mounted inthe top of theframe and in a supporting bar 18. Each is normally held to its upper limit by means of a spring 19, and the shoulder 20 is formed on each as clearly shown in Fi 19.

The first key bar indicated by the numeral 21 is designed to print the numeral 0, and is not provided with any notch, and does not affect the lever 12: The adjoining key bar has its bar 13 to the distance required for bringing the second type into printing position. The shoulders 20 are arranged in different position on all of the key bars 17 so that each when moved to its lower limit will operate the lever 12 in such manner as to bring the corresponding type to printing position.

I have provided for printing from the type on the segmental bars 13 as follows: Mounted beneath the sliding key bars is a crank shaft 22, having crank arms in position to be engaged by the key bars 17 when depressed. ()n the rear end of each of the crank shafts 22 is a crank arm 24. The numeral 25 indicates a carriage slidingly riage 25 is a series of supports 31, to each of which I have pivoted a printing hammer 32. This hammer is normally held away from the type by means of the spring Each hammer is formed'witliia slot 34 into which the crank shaft 24 is.placed. By this construction, a depression of any one of the keys 17, or the he 21, will operate to first set the type bearing segments 13 to proper position, andwill then operate the printing hammers. The crank arms 24 are made long enough so that the carriage 25 may be shifted transversely of the machine to the required amount without affecting the operation of the rintinghammen' '1 1e ribbon support comprises two brackets 35, mounted at opposite sides of the machine framc,and containing the shaft 36, having a ribbon spool 37 at its top, and a bevel pinion 38 at its lower end. These brackets 35 are fixed to the shafts 3S) and 40,

which are slidingly mounted in the frame,

and I have provided for sliding the shafts as follows: Pivotc'd to one side of the machine frame is a lever 41, connected by a rod 42 with a bell crank lever 43, fulerumed to a bracket 44, on one of the uprights 26. The other end of the bell crank lever is connected to the brackets'35, and when the lever 41 is depressed, the shafts 3i) and 40, together with the brackets 35, are shifted transversely of. the machine. On each end ofthe roller 28, is a ratchet wheel 45, having projecting outwardly from its outer surface two teeth 46. These teeth are designedto engage the bevel pinions 38, and when one of said ratchet wheels is in position in engagement with one of the bevel inions 38, it will be rotated as the paporis at vanced, andwill turn the bevel pimon 38 two spaces during each revolution of the ratchet wheel. This will be suiiicient to advance the ribbon spools the desired amount, and when the lever 41 is operated in any direction to shift the ribbon device, the motion of the ribbon winding spools will be reversed.

I have provided for advancing the paper roll 28 as follows: Fulcrumed to the machine frame at one side is a lever 47 having pivoted to its lower end a rod 48, provided with a tooth 49. This tooth is normally in engagement with the ratchet wheel 45, and is so arranged that a movement of the lever 47 will turn the paper roll 28 the proper distance for spacing apart the lines in a column of figures.

I have provided means for carrying totals from one type bearing segmental bar 13 to the others, and forvisibly indicating to the o orator at all times as follows: Hounted in t 10 machine frame 10 is a shaft 50 having a I have arranged a series of nlunerals 54, also consecutively arranged from U to 9, so disposed with relation to the other numerals 53, that when the numeral 1 on one wheel is in printing position, that is adjacent to the a'mmer 32, the numeral 1 of the series 54 Formed on of rate et teeth, 56. Rotatably mounted on the hub of each of the wheels 52, is a wheel 57, having cog teeth formed thereon, and

the'teeth 58. .52 is a splring actuated pawl 60, designed to ratchet teeth 59 formed thereon, adjacent to Carried by each of the wheels engage t e adjacent set of ratchet teeth 59. Between each wheel 52 and the adjacent wheel 57, is a spacing washer 61, held against rotation on the shaft 50 by means of the arms 62 resting upon the support 63, as clearly shown in Fig. 7.

Formed within each of the wheels 52 is a circular recess 64, surrounding'the shaft 50.

with the shaft 50.

In this recess is a lug 65, and fixed to the shaft 50 is a pin 66. This pin. 66 is normally in such position that the whcel-52 may freely rotate without having the pin 66 engage the However, when the shaft 50 is the spring 51, the pin 66 will engage the lug 65, and thus cause the wheel 52 to rotate I have provided for manually moving the shaft 50, and for rotating it, as follows: Formed on the frame 10 is a clutch member 67 surrounding the shaft 50.

" Fixed to the end of the shaft is a hand wheel 68., having a clutch member 69 formed thereon to coaet with the clutch member 67. By .means of this mechanism, if it is desired to move ,all of the wheels 52 by hand, the operator grasps the hand wheel 68 and pulls it out of engagement with the clutch memher 67, thus bringing allof the pins 66 into engagement with the lugs 65. He then turns the hand wheel 68, and in this way moves all of the wheels 52. In this connection, it is to be understood that thelugs 65 are so arranged within the wheels 52, that when the shaft 50. has been turned a com- 'plete revolution, with the

clutch members

67 and 69 out of engagement, all of the wheels 52 will be moved to position with the numerale 0, all in printing position, and in position Where they will be visible through the openings 55, so that in this way the machine may be cleared at any time.

I have provided means for carrying totals from one wheel to the next as follows: On the rear side of each of the wheels 52, is, a laterally projecting pin 70. Pivoted to the forwar end of each of the arms 62, is a lever 71, having pivoted to its upper end an arm 72, formed with an inclined shoulder 73, and inclined shoulder 74. Pivotally mounted on top of the arm 72 is a spring actuated pawl 75, normally held by its spring in'engagement with the ratchet teeth 56 of the adjacent wheel 52, to the left. Arranged below thearm 72 is a shaft 76, supported by the machine frame, and carrying a series of pawls 77, each of which has two lateral pro: {)ections 78 and 79 on one side, with a space etween them. The 0 )eration of this carrying mechanism is-as f0 lows: When the'first Wheel to the right has been moved to posi-- tion, with. the numeral 9 thereon in its printing ]position and visible through. the opening in t. 1e top of the frame, where the pin 70 is in position in engagement with the shoulder 74 of the pawl 72, as clearly shown in Fig. 2'. Then when the wheel 52 is moved one type space further, the pin 70 will throw the arm 72 toward the front of the machine, and the pawl connected to the arm 72 will cause the next wheel 52 to thecleft. to be moved one type space. As soon as the arm 72 has been operated to move the adjacent wheel 52 one type space as above described, the inclined shoulder 73 of the arm 72, will strike upon the shaft 76, and thus elevate the arm 72 out of the path of the pin 70, as shown in Fig. 14, so that if the wheel 52 to the right should have been moved more than one type space, the wheel to the left will be moved only one type space and no fartherj A in clearing up the machine by turning the hand wheel 68 as before describedwthe pins 70 would be stopped in position ih engagement with the shoulder 74 of the typewheels 52, and in order to start the machine in operation after it has been cleared, it is necessary that thesepins 70 be in position past the shouldcrs 74 of the pawl 72. To )rovide for this actuated positioning of the wheels 52, I have placed on the shaft 76, a crank arm 80, de signed to enter a notch 8'1 formed in a disk 81, fixed to the hub of the hand wheel 68, as clearly shown in Figs. 3 and 9. as before described, are fixed to this shaft 76, and they are so arranged'that when the crank arm is resting in the notch 81 as shown in Fig. 3, the arms 77 will stand in the position shown in Fig. 14, and when they are in this position, the pins 70 may be passed through )etween the ugs 7S and 79 of the arms 77, but when. the hand wheel 68 is turned, then the rear end of the crank arm 80 will be elevated, thus bringing the arms 77 to the posi tion shown in Fig. 15, where the pins 70 will strike against the lugs 79, andthus all of the wheels 52 will be stopped in thisposition, which (position is such that the pins 70 will be beyon the shoulders 74 of the arms72, so that when startingto operate the machine after it has been cleared, the pins 70. will not engage the shoulders 74,:until after the wheels 52 have made a complete revolution,

The arms 77,

it being understood that as soon as the hand wheel 68 has com leted. its, revolution, the,

a m 7 7 willlagein. rep to the n s fii nshawn in Fig. 14, where the pins 70 will not inter.- fere, or engage with the arms 72, or the lugs thereon. In this connection, it is to be understood that when all of the wheels 52 have been turned to position, with the pins 7 thereon resting against the lugs 79 as shown in Fi 15, all of the numerals 0 on the adding whee s will be in printing position, and be visible through the openings inthe frame. The lugs 78 are for the purpose of engaging the lugs 73 on the arm 72, and holding the arm 72 in an elevated position, as shown in Fig. 15, so that the lugs 74'will not stand in the path of the pins 70.

From the foregoing description it will he understood that the printing of numerals in the first instance will bedone from the type on the segmental bars 13. I have provided means for printing totals at any time direct from the wheels 52, as follows: I have described heretofore, the movable carriage on which the printing hammers 32 are mounted. These hammers normally stand in position to irint from the type on the segmental bars 13,

mt they may be shifted as shown by dotted lines ,in Fig. 8, to positiongfor printing from the type wheels 52. This mechanism eomprises a key bar 82 in each column of key )tLI'S, normally held by a spring in the same way as the key bar 17, and each iirovided near their lower end with a lug 83. i ounted adjacent to the lug 83 is a shaft 84 having a forwardly projecting crank arm 85, to which a cross rod 86 is attached. This rod is in the path of the lugs 83 so that when the key 82-is depressed, the lug 83 will engage the rod 84 and push it downwardly. Fixed to the shaft 84 is a rod 87 connected to the crank arm 88 and a shaft 89, the lower end of which is provided with an arm 90 to enter a notch 91, formed in the sliding carriage 25, as shown in Fig. 18. in this way, the first effect of a downward movement of any of the key bars 82, will be to shift the carriage to position with the hammers 32'opposite to the wheels 52. The next effect of a downwardly movement of any of these key bars 82, will be to have their lower ends strike upon the crank arms 23, and thus actuate the printing hammers- The said key bars are shown in this position in Fig. 11, by dotted lines. I have also provided means whereby the entire total mav be printed by the depression ofa single key, as follows: On each of the key bars, 82 except the first one to the right, I have formed a lateral extension 92, to overlap a pin 93 formed on the adjacent key board to the right. By this means, and assuming that the total sum to be printed was in four figures, then theoperator would depress the key bar 82 in the fourth row, and the extension 92 would engage the pins 93 and thus depress all four of the key barsto the right, as shown by dotted lines in Fig. 11.

In pra'ictical use, and assuming that the seams machine is in its normal position, and assuming that the number 5555 is to be printed, then the operator depresses the key bearing the numeral 5, in the fourth column, then the key bearing the numeral in the third column, then in the second, and then in the first; The printing will be done direct from the segmental bars 13, and the adding wheels 52 will have no part in the operation, except that they will each be moved by the pawls so that the numerals thereon will stand in position with the numerals 5 on the first four Wheels in printing position, andwith the numerals 5 of the same wheels of the set shown in black in Fig. 8, ap earing through the openings in the top of t 1e frame; Then the operator depresses the lever 47, thus advane ing the paper one line space, thcn the operator proceeds to print the next number in the same way. Assuming that the second number to be printed contains the last numeral of a value of five or more figures, then the printing is all done from the segmental bars in the same way as before described, but the carrying mechanism will cause the second adding wheel to the right to be moved one type space, thus carrying ten from the first wheel to the right, to the second wheel. The operator proceeds in this Way until the column of figures to be added has been completed, then'assuming that it is desired to print the total, and the total number comprises five figures, he then depresses the fifth one of the key bars 82, thus shifting the carriage to bring the printing hammers in operative position with relation to the adding Wheels, and immediately thereafter operat ing the printing hammers jointly to print the total.- Assuming that, it is desired to return all of the adding wheels to normal position with the numerals O appearing in printing position through the openings in the frame, then the hand wheel 68 is grasped and moved to release the clutch members 67, and then rotated a complete revolution, this will have the effect of causing all of the pins 66 to engage the lugs 65,.and thus move all of the adding wheels to the desired point, and at the same time it will operate the crank. arm 80 in such manner as to bring the arms 77 into the path of the pins 70, thus positively stopping all of the adding wheels in the proper position, and at the same time allowing these pins to pass the shoulders 74 of the arm 72 so that the machine will be in position or starting a new operation.
