Specification of Letters Patent.

Patented May 11, 1915.

Application filed August 29, 1904, Serial No. 222,572. Renewed November 2, 1914. Serial No. 8B,974.

To all whom it may concern: v

. Be it known that I, F RANK C. RmsoHE, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Calculating-Machines, of which the following is a full, clear,-

and exact description, such as will enable others skilled in the art to, which it appertains to make and use the same, reference being had to the accompanying drawings, forming partof this specification, in which- Figure 1 is a vertical sectional view through the rear end of an adding machine showing my improvement in position; Fig. 2 is a front elevational view of'a portion of the carriage on an adding machine used' in connection with my improvement; Fig. 3 is a sectional View taken at right angles to the view shown in Fig. 1; Fig. 4 is a detail View showing the parts connected with the total key for insuring the printing of the total under a given column of figures; Fig. 5 is a similar view showing certain of the parts illustrated in Fig. 4, in a different position; Fig. 6 is a detail view of the means for shifting the paper carriage; Figs. 7, 8, and 9 are similar views showing the parts in different positions; Fig. 10 is a view illustrating a slip of paper upon which two columns of figures are printed, one of said columns having a footing indicating the total thereof; and Fig. 11 is a vertical sectional view through the keyboard of the adding machine to which my improvement is applied.

This invention relates to a new and useful improvementin adding or calculating machines of that type shown in United States Letters Patent No. 751,207 granted to me February 2, 1904;. \Vhile I have illustrated certain old parts of my said patent, it will be obvious that I do not confine my invention to the particular type of machine shown in my said patent as the same may be employed in connection with other types or makes of adding machines.

The object of my present invention is to print two or more columns of figures on a piece of paper and so control the adding mechanism that but one of'said columns Wlll be registered in the accumulaton- The particular work which my present 1nvention is designed to accomplish is in connection with the listing of insurance policies and the accumulation ofthe premiums paid printed on a strip of paper carried by the.

I or to be paid in connection with the several policies. While I have referred to insurance policies it is obvious that the invention is capable of many uses" where the items to be added in a column are to be identified by identifying symbols placed in a separate column adjacent to the items to be added. For instance, the invention is capable of use in railroad ofiices where the number of the car is to be printed and opposite said number the earnings of the car for a given period of time. There is no necessity for adding the car numbers together as such a total would be meaningless,but it is desirable to add the earnings of the car and to fin'd the total thereof.

In order to illustrate the work done by my improved machine, I have, in Fig. 10,

illustrated a piece of paper containing two ployed in carrying out my present invention I will refer to Patent No. 751,207, before referred to, as containing all the essential features of an adding and listing machine such as usually found in machines of this character.

To briefly describe the operation of this machine I will state that there is a key board containing series of keys numbered from one to nine consecutively. To set up an example on the key board the proper keys are depressed and then an operating handle is pulled which causes the example to be paper carriage across tlie to'pof the machine, the items set up on the key board being introduced into the accumulator by the same operation of the handle. After a number of items have been setup on the key board, printed on the slip of paper and introduced into the machine, the total key is operated which enables the operator, by again pulling the handle, to print the totalv of the items which have been introduced into the totalizer.

In my present machine there are means provided whereby when the carriage is in one position, to Wit, that in which the identification numbers are printed in their proper column, the totalizer is thrown out of mesh and when the handle is operated it only effects a printing of the numbers set up on the key board and automatically adjusts the position of the carriage so as to locate the paper to print the next item set up on the key board in the item column. This shifting of the carriage also renders the totalizer effective, that is, when the next item is set up on the key board and the handle operated it will print said item and also introduce said item into the totalizer,

to be accumulated. This second operation of the handle in printing the item to be added automatically shifts the carriage again to locate the identification column over the printing type so that the next iden-.

tification number will appear in its proper place but not be added in the accumulator. To avoid printing the total of the item column under the identification column, means is employed to lock the total key when the carriage is in aposition to print under the identification column, an extra stroke of the handle being necessary to shift the carriage and locate the total as a footing to its proper column.

With these objects in View, the invention consists in the construction, arrangement and combination of the several parts all as will be hereinafter described and afterwards pointed out in the claims.

In order to identify the parts illustrated in the accompanying drawings with corresponding parts illustrated and described in my aforesaid Patent N 0. 751,207, I will, as far as I can consistently do so, use the same numerals of reference for the old parts illus trated in this application as were used to illustrate the same parts shown in said patent.

The slide bar 25 illustrated in dotted lines in Fig. 4-, carries a pivoted rack 84 which is adjustably positioned according to the depressions of the keys in the key board, which keys are not here shown, said slide bar moving forwardly upon the operation of the handle and upon reaching their forward position, and just before the handle reaches the limit of its forward stroke, the

racks are thrown into mesh with the accumulator wheels 97 to which are geared the indicator wheels 99 containing numbers on their peripheries to indicate to the operator the total of the items registered in the accumulator. I

The rear ends of the slide bars 25 carry upright standards 128 in the upper ends of which are mounted independently movable the machine.

printing type 129. When the slide bar moves forward, and just about the time that the racks 8% are thrown into mesh with the accumulator wheels, the' printing hammers 131 are released to force the type in the printing line up against the ribbon to make a printing impression upon the sheet of paper designated at X, which paperpasses under a'platen 133. This platen is mounted in a laterally adjustable carriage A and is provided at one end with a ratchet wheel, not shown, with which cooperates a paperfeeding pawl deriving its motion from a rock shaft B mounted in the carriage, which rock shaft has a pendent bail b carrying a collar 1)" designed to cooperate with a Vibrating arm 138.

The construction of the paper carriage and the. means for feeding the paper in the different lateral positions of the carriage is shown in my Patent No. (554,181, of July EH, 1900, and I will not describe the same in detail here except to say that each operation of the handle causes the bar 138 to be vibrated.

The paper carriage is hinged at a, the hinged bearing being carried by a laterally moving saddle having ball races cooperating with balls running in suitable ways formed in a casting (l, secured to the top of A indicates a handle extending forwardly from the paper carriage and cooperating with a bar I), which shown in Fig. 2, is notched to receive the handle, each end of the notch being provided with a depression (Z, so that when the handle rests in said depression it is not liable to become accident-ally displaced.

Referring now to Fig. 8, it will be seen that the rear bar A of the paper carriage is provided with a cam face a with which cooperates a roller on the upper end of the arm E. When the carriage is in the position shown in Fig. 3,-that is, E will be depressed, but when said carriage is shifted to the left the bar E rises and its roller occupies the deepest portion of the cam. This bar E, whose position is controlled by the lateral position of the carriage, in turn controls the introduction or non-introduction of the items in the accu- Inulator. When the bar is depressed the type will print in the identification column, and the items will not be introduced into the accumulator. On the other-hand, when the bar is elevated the items will be printed in the item column and introduced into the accumulator.

The bar E, as shown in Fig. 1, is guided in its vertical movement and connected to a lever F, which lever at its other end is connected to a link G. The opposite end of this link is connected to a bar 93 which is fulcrumed in a rock arm 92 having a limited motion between stops 92 The forward end bar, as

to the right, the bar When an example is set up on the key board the forward movement of the handle permits the slide bars to move to their adjusted positions respectively, and when the slide bars have reached their extreme forward position (the greatest length of movement being when the 9 key is depressed) the projection 91 engages the arm 92 and a continued forward movement of the handle will ordinarily operate the arm 88 so as to engage all of the pivoted racks with their respective adding wheels. However, the forward end of bar 93'is'provided with a recess 93 which is designed to cooperate with a pin 88 on the arm 88; A spring 93 tends to force the forward end of arm 93 down so that the recess in the lower edge thereof will embrace the pin 88.

Arm 88/, as described in my said Patent No. 751,207, is provided with a cam slot in 1ts upper end for raising and lowering the ,cam roller 87 mounted on one of the side arms of the frame which carries the rod 86 passing through the slots in the pivoted racks 84. Thus, if the arm 88 is moved forwardly through the mechanism just described, the racks are thrown into engagement with the totalizer wheels and when said arm 88 is moved rcarwardly the pivoted racks are disengaged from said totalizer wheel.

By referringto Fig. 5 it will be observed that the bar E is raised, which means that the arm 93 is connected to the arm 88 and consequently the items set up on the key board will, when the handle is operated, be introduced into the totalizer as long as the parts remain in this position, to wit, as long as the arm88 is vibrated by the arm 93. However, should the carriage shift so as to depress the bar E the arm 93 will be raised and in its raised position idly vibrate, and not engage the arm 88 so as to cause an engagement between the pivoted racks and the slide bars with the totalizer Wheels, as shown in Fig. 4.

From the above it will be seen that when the carriage is in a position to have the type print in theidentilication column the bar E will bedepressed and when the handle is operated to effect a printing impression there will be no introduction of the items setup on the key board into the totalizer;

but when the carriage is shifted so as to locate-the item column over the printing type, the bar E will be raised so as to engage the bar 93 with the arm 88 and effect an introduction of the items set up on the'key board and printed in the item column into the totalizer.

I will now describe how the carriage A is shifted at each operation of the handle. The rear end of rod 62 which is operated at each operation of the handle, is provided with a rack in mesh with the segmental gear 77. This gear is fixed upon and rocks the shaft 78, said shaft in turn carrying a rock arm 79 connected by a link 80 to a lever 81. The forward end of lever 81 cooperates with the transferring mechanism, not shown in the drawings, while the rear end of said lever is connected to the rod of a plunger arranged in a dash pot 82. This dash pot controls the speed at which the operating handle and its connected parts may move, and at every operation of the handle the lever 81 is vibrated.

Lever 81 carries a pin or projection H which cooperates with certain devices whereby the motion of said lever 81 is transmitted to the carriage A and said carriage is shifted to the right or to the left at each succeeding operation of the lever.

Carriage A is provided with a projection engaged by the slotted upper end of a bell crank lever I, the lower end of said bell crank lever being also slotted so as to receive a finger j on a rocking lever J. The bell crank lever I is mounted on a cross bar 7' on the frame of the machine, and the lever J is preferably mounted on the side framing of the machine. Each end of lever J carries a hook K and K which are designed to cooperate with the pin H on the lever 81. Springs 7: tend to force the hooks K and K into engagement with the pin H. Each hook is provided with a guard wing L and L cooperating with stops is on the hooks, said guard wings being held normally over the hooks to prevent the engagement-of the pin H, by means of springs Z.

It will he noted that in the closed position of the guard wings the outer edges thereof, Z, form tracks over which the pin H .rides, and when the pin gets under the edges Z the guard wings are lifted so as to permit the pin H to enter the hooks and rock the lever J in one direction or the other, de pending upon which hook is engaged by the pm. 7

In the position of the parts shown in Fig. 6, the pin H is in engagement with tie hook K and will, when the lever 81 is raised in the direction of the arrow in Fig. 6 move upwardly riding under the edge of the guard wing L and release said guard wing so that the guard wing will occupy the position shown in Fig. 7. At the same time the pin number in the identification column.

will lift the guard wing L on the hook K and become engaged with said hook K so that when the lever 81 moves in the direction of the arrow in Fig. 7 the lever J will be rocked to the position in Fig. 8. It will be noticed that the movement of the pin H in an upward direction is idle and alternately it becomes engaged with the hook K or K on its down stroke, which down stroke is effective. The down stroke of lever 81 is coincident with the rearward movement of the handle so that the carriage is shifted when the handle is being returned to its home position. The carriage is shifted at this time to avoid interference with the printing impression and paper feeding devices, both of which are identified and connected with the forward movement of the handle. When the parts reach the position shown in Fig. 7 it will be observed that the pin H is in engagement with the hook K, and when the lever 81 descends in the direction of the arrow shown in Fig. 7 it will cause the lever J to rock to the position shown in Fig. 8. In its descent the pin II will ride over the outer edge of the guard wing L and be located under said guard wing in readiness, on its next upward movement to lift theguard wing L on the hook K, as shown in Fig. 9. NVhen the parts reach the position shown in Fig. 9, the pin is in engagement with the hook K, and on its next descent the lever J will be rocked to the position shown in Fig. 6. In its descent it will ride over the outer edge 0f the guard wing L and upon reaching normal position the pin will be located under said guard wing as shown in Fig. 6, in readiness to lift it and enter the recess of hook K, as shown in Fig. 7.

I have before stated that when the carriage is in its position to the right it will print numbers1n the identification column, and it is obvious that the line-spacing mechanism must be rendered inoperative when the handle is pulled to effect the printing in the item column, otherwise the item which is next set up on the key board, introduced into the totalizer and printed, would not be printed opposite its proper In order to effect this the collar bbefore described is so positioned on the bail Z) as to be in the path of the vibrating arm 138 previous to printing the character or characters in the identification column so that the feeding of the paper will be effected prior to printing in the identification column. However, after the carriage is shifted to the item column and a number is set up on the key board, which is to be introduced into the totalizer and printed opposite the identification column, the changed position of the carriage will locate the collar 6'' out of the path of the arm 138% that when the handle is operated the arm 138 will not engage the collar to rock the bail to operate the linespacing mechanism for the paper. It will thus be clear that the feeding of the paper is initially efiected before the impression is made from the type in the identification column, and while the carriage is automatically shifted over to the item column no feeding of the paper takes place until the carriage is again shifted back in a position so that the printing can be effected in the identification column.

It will be obvious that after the item has been printed in the item. column the carriage will be shifted to the identification column and should it be possible to operate the total key to take the total of the items in the item column, the total would be printed under the identification column which would be confusing. To avoid this the total key is locked when printing is to be effected in the identification column, and is automatically unlocked when printing is to be effected in the item colunm. After all of the characters are printed in both the identification and item columns and it is desired to get the total, the carriage must first be moved back so that the type will be oppo'sitethe identification column, this being necessary in order to feed the paper one-line space. As soon as this feeding of the paper is effected the carriage will automatically move back to the item column, at the same time unlocking the total key and by actuating the total key and then the handle the total will be printed at the end of the proper-column.

Referring now to Fig. 4:, 1 18 indicates the total key pivotally mounted at the front end of the machine and preferably arranged at the left-hand frame plate. If it is desired to obtain a total, the key 148 is ulled forwardly and if held in its forwar position it will, after the handle starts on its return movement, retain the total in the machine. If, on the other hand, the total key is released, just after the handle has started on its forward movement, 'it will fly back when the handle reaches the limit of its for,- ward stroke and the totalizer will be cleared.

Upon the operation of the total key, as described in my said Patent No. 7 51,207, all of the slide bars are released; the key board, if an example is set up therein, is released and prevented from being operated, while the total key is in other than a normal position'; devices are set into position to engage and restrain unnecessary forward movement of the slide bars; a lock is operatively positioned'to prevent the restoration of the total key until the handle has at least completed its forward movement; the pivoted racks are engaged with the adding wheels; the means ordinarily operated by the handle (when the total key is home) to engage the racks with the adding wheels, is rendered inoperative; and the ribbon spools are shifted so that the total is printed in a color different'from that of which its items are composed. We are not concerned here in the means for releasing the slide bars, the means for releasing the keyboard, the means for restoring the forw'ardmovement of the slide bars, etc., but in order to identify the several parts attention is directed to the fact that when the total key I LS-is pulled forwardly a rocking lever 150 is operated by means of the link 149. This rocking lever carries a link 168 which is provided with an inverted L-shaped slot in its rear end, which slot cooperates with a stud 169 on the lever 88. In

the normal position of the machine whenthe total key is at home, the stud plays in the horizontal member of the slot; but when the rear end of the lever 168, through the medium of the lateral projection 98 on the forward end of link 93, raises said link out of engagement with the arm 88. Engagement between link 93 and arm 88 is through the medium of a pin 88 entering the recess 98". Thus when the total key is operated the link 93 is disengaged fromthe arm 88.

Topreventthe total key from being effectively operated after an item has been printed and before an extra stroke of the. handle is made, I provide a spring-pressed guard-Y which normally closes the vertical portion of the slot in which the pin 169 opcrates, and prevents the rear end of the lever 168 from being elevated when the cam riage is in the wrong position. When the arm 93 is disengaged from the arm 88, as

in the-printing of identification numbers,

the guard Y, which is mounted onan extension of the lever 168, closes the vertical portion'of the slot and if it is attempted to operate the total key when the parts are in this position, the guard will strike the pin 169 and prevent the rear end of the lever 168 from being elevated. However, when the guard is in a position to print an item which is in a proper position for the total to be printed, the arm 93 is depressed and in en gagement with the lever 88 and the projection 93 contacts with a finger on the guard and carries said guard out of the path of the pin 169. \Vhen the parts are in this position, which is shown in Fig. 5, it will be obvious that when the total key is pulled forward and the rear end of lever 168 elevated, it will'lift the forward end of bar 93 to disengage it from the arm 88 as in the ordinary operation of taking a total,

but this movement will not disturb the retracted' position of the guard and conse quently the pin 169 may enter the vertical portion of the inverted L-shaped siot in the rear end of lever168.

I am aware that minor changes in the construction, arrangement and combination of the several parts of my device can be made and substitutedfor those herein shown and described without in the least departing from the nature and principle of my invention.
