POWER-OPERATED CALCULATING TYPE-WRITER. I

7 Application filed February 16, 1911.

To all whom it may concern Be it known that we, EDWARD I-I. PALMER and lVILLiAM S. KrNsLnY,'of Reading, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Power-Operated Calculating Type-lVriters, of which the following is a specification.

This invention relates to a calculating apparatus adapted for operation simultaneously with a typewriting machine, under the control of the latter, for indicating totals of figures which are being written upon the sheet by the typewriting machine.

In some respects, the present machine resembles that which forms the subject matter of our application filed December 16, 1909, Serial No. 533,453, the similarities, however, residing in the particular counteractuating rack and pinion mechanism, and in the mechanism for carrying from one counter to the next.

In the application above referred to, the operation is entirely a manual one, and when adding as well as the typewriting of numerals is to be performed, a special set of key levers is employed.

One of the objects of our present invention is to provide a machine or apparatus of this character employing power other than that obtained from the operator of the machine, such as an electric motor.

Another object of the present invention is to provide an apparatus requiring no extra set of key levers, but employing the regular numeral and character key levers of the typewriter either for writing without performing any calculating operation, or for both calculating and making a typewritten record of the several amounts involved in the calculation.

The invention herein described and claimed does not relate to the general struc ture of the typewriter machine excepting in so far as portions of the typewriter machine are employed to control the computations of calculations, and therefore the present invention specifically relates especially to a power-operated calculating mechanism, although at the same time there is a writing or recording operation taking place.

Specification. of Letters Patent.

Patented Mar. 21, 1916.

Serial No. 608,955.

In the accompanying drawings, we illustrate only so much of the apparatus as is necessary to an understanding of the present invention, reference being had, if necessary, to our application above referred to for detail description of the operation of the counters and the carrying mechanism.

Of said drawings: Figure 1 is a plan view of parts of the front half of the machine, full size, many of the members or elements which are duplicates being omitted to avoid confusion; Fig. 2 is a view similar to Fig. 1, showing the rear part of the mechanism; Fig. 3 represents a section on line 38 of Figs. 1 and 2; Fig. {l is a detail plan view of a portion of the selecting mechanism shown in Fig. 2. Fig. 5 is a detail front elevation of the slide employed for shifting the apparatus to perform subtraction instead of addition.

Similar reference characters indicate the same or similar parts in all the figures.

The mechanism is practically an attachment for an ordinary typewriter machine, such attachment being placed under the t pewriter machine as explained in our earlier application referred to. The base of the attachment is indicated at 5, side portions being shown at 6.

Referring to Fig. "2, at the top thereof, a portion of a constantly driven shaft 7 is indicated, it being understood that this main shaft 7 may be constantly driven by a suitable electric motor. Carried by the shaft 7 is a ratchet wheel 8 with which a pawl 9'00- operates. The pawl 9 is carried by a disk 10, carried by a shaft 11, the structure being such that whenever the pawl is in engagement with the ratchet, the shaft will be rotated. In general features. this mechanism for rotating the shaft 11 is similar to the mechanism shown in the application filed November 14, 1908, Serial No. 462,584, by Palmer and Berry, with this difference, that in the said Palmer and Berry application there is a shaft running through a series of cylindrical members. only one of which at a time is given a single rotation, while in the present invention the entire shaft 11 is given one complete rotation and stopped every timethat a key is depressed. For present purposes it will be suflicient to explain that the pawl 9 has projecting from its pivot a heel 12 adapted to contact with the upper end of a post 13, the engagement of the pawl with the ratchet and the disengage: ment therefrom being controlled by a lever 14 pivoted at 15 and shifted toward the right or left in Fig. 3 by means of a light red The p t n is sueh that every time that the rod 16 is shifted slightly toward the right in Fig. 8, it causes the engagement of' the pawl 9 with the ratchet 8 so that the shaft 11 will be rotated by the motor, this rotation being limited to a sine complete one, t e t r .2 o th p 9 co ng? t a s p ga nst th pp end of post 13 after the pawl is disengaged, thus ins n ly t pping m eme t of the s a tu th d tail of t is me ani m are not n es ary he e n sin e they are fully illusated an described i th aid Balmer and Be y pp i n.- The shaft 1 ha re upo t h ee sam the PHPPQSQS o uh eh il be h e naf e esoribe Ob- "ie s y, in tea f cause, eccentr s u h a hown in he sa Pa mer and Berry app ication, may be empleyed.

One of the cams carried by the shaft 11 as shown in Fig. 2 is intermediate with the ends of the shaft and is indicated at 17, said earn acting upon a roll 18 carried by an arm of r k s a 20- sa o k shaft having at each nd an arm 21,111 ahn m ut with the arm 19. The two arms 21 are connected bv links 22 w th r cipr at g Plate 23 ch s h rei after ref r d to. as he earriag-e, the pivotal print of the links 22 with aid ar iag being ndica e a 4.

IHOVGIHBDCS toward the right or left of the machine by means of slcts and suitable supporting pins. The operation of this selector plate will be described more fully in detail hereinafter. i ii The tongues 36 are so spaced that only one of them at a time can be located behind the upper end of one of the levers 31. When a stop 36 is so located, the movement of the carriagegg toward the left in Fig. 3 will cause the lower end of the stopped lever 31 to swing toward the left and so slide the bar 35 to which it is. connected also toward the left, but all of the other levers 31 that are connected with the carriage 23, wil swing on their pivots in the other direction be-:

cause their forked ends will remain in engagement with the pins 34 on actuating bars that are not moved, such idle levers 31 sin1- ply swinging on their pivots 32, their upper ends passing in between the s op tongues 36. A rack arm 41 is pivotally connected at 42 to. each actuating bar 35', springs 43 being employed to preserve he operative engagement of the racks w th the pinions 45 in the same manner as in the Palmer and Kinsley application hereinbefcre referred to 'The disks of the counters are indicated at 46, said disks, being carried at th upper ends of spindles 47 on which the pinions 45 are mounted, The extreme ends of the rack arms 41 are wedge-shaped as 50, to engage p ns carried by arms 51 pivoted at 52, each of said arms 51 having an arm 54 and an arm 55, all substantially as shown in the said Palmer and Kinsley application.

or the puruo es f xp a n ng the present invention it is not necessarv to refer to the operation of the counters, either for sing e step. m em nt or t e carrying mo ements furtherthan to that all ofthe eounting and carrying movements are controlled by the indeoeudentreciprocation of the racks 41 through their actuating bars 85.

ljle will. now describe the mechanism by which the selector plate is reeiprocated or adjusted transversely in accordance with the movements. of the typewriter carriage (not illustrated), so that the proper stop tongue 3 will, be brought in position for the upper end of a lever 31 to abut so that the lower end of such lever will cause the actuation ofthe proper counter, A tape 56, (Fig, 2) is. attached at one end (not shown) to. a Part of the transversely movable carriage of the typewriter machine. said tape passingover an idle pulley 5,7 and having its other end attached to Spring-operated drum 58 so that the tape 5 will partake teel one, suitably thereto a its shoulder 59. A lever 60 pivotally supported at 61 and held in one direction by a spring 62 has a round end or knob 63, and is provided with a pin 64 in the path of movement of the tape shoulder 59. In order to limit the movement of the lever 60 under the influence of the spring 62, a suitable stop device is employed, such device preferably consisting of a fiXed rod 65 about which the spring 62 is coiled, the said rod being fixed at one end to a suitable member 6, of the frame and having its other end in position to serve as a step for the side of lever 60. The shoulder 59 carried by the tape moves the lever 60 in one direction, and the spring 62 in the opposite direction. It may be mentioned here that this mechanism is especially arranged for use of the calculating mechanism when the numerals are being written at the right of the sheet in the typewriting machine. But by changing the positivn of the shoulder 59 relatively to the length of the tape, the work may be performed on any lateral portion of the sheet. As the carriage of the typewriter machine travels toward the left of said machine, the spring-operated drum 5S winds up the tape andcauses the shoulder 59 to swing the lever 60, the firstmovement of which would bring one of the tongues 36 in position to serve as an abutment for the first lever 31, and a further movement of the lever 60 will cause the shifting along of the selector plate mem rer 37 to bring the next tongue 36 opposite the upper end of the next lever 31, and so on.

The first series of step movements of the lever 60 causes one transverse or sliding movement of the section 37 of the selector plate under the tension of the spring e0. This is because the section 37 can slide relatively to the section 38, while the spring 40 is connected to both sections 37 and 38. And as one of the screws or pins (66 in Figs. 2 and l serves as a stop to limit the extent of movement of the section 38 toward the left, the said pin or screw 66 acts the same as though it was the anchoring point for the end of the spring 40, and so continues to act as an anchoring point until section 37 has,

step by step, been moved to the right until all of its vernier-like positions of said slide have brought each one of its tongues successively into position to act as a temporary fulcrum for one of the upright rock-arms 31. The last of these positions will bring the knob 63 in contact with the shoulder or abutment 39 on selector section 38. The selector section 37 has a shoulder 67 which bears against the knob 63 of l ver 60 and consequently, as the lever 60 is shifted along by the tape shoulder, the shoulder 67 follows it under the influence of spring 40, so that the section 37 will partake of the step movements of the lever 60. lVhen the section 37 is moved along as far as permitted by the guide pins or screws 68, it is stopped, and at this time the knob 63 of lever 60 contacts with the end of the projection 39 so that continued movement of the lever 60 causes the section 38 to be shifted along with a step movement, the spring to yielding to permit of this shifting.

The reason for making the selector plate in two sections, 37, 38, as described, is because the amount of movement that would be required if made of one piece would cause the stop tcngues to be shifted along to such positions that they would interfere with other parts of the mechanism. Of course on the return movement of the carriage the lever 60 follows the movement of the tape shoulder and first permits the selector section 38 to return to normal position unoer the influence of spring 40 and then owing to the knob 63 contacting with the shoulder 67 the selector section 37 is carried to its normal position shown in Fig. 2, the spring 62 be ing of course of greater strength than the spring etO. The relative spacing of the stop tongues 36, and the relative spacing of the levers 31, is such that no tongue 36 opposes movement of a lever 31 at the point where the decimal point and the commas employed in the writing of numerals occur.

In order that the selector plate sections may be moved out of position when the typewritin machine is being used to print the upper case characters of the numeral key levers, or when it is desired to write numerals without actuating the calculating mechanism the said selector plate sections are mounted upon a bar 69 which is mounted at its end on pivots 7 0. One of said pivots extends through a side plate 6 of the frame and is provided with a handle 71. This pivotal mounting of the bar 69 on which the selector sections are slidably mounted enables the stop tongues 36 to be raised above the plane of the tops of the levers 31. This swinging movement may be effected by the operator actuating the handle 71 whenever it is desired to typewrite numerals without doing any calculating or print upper case characters. In order that this bar 69 may be actuated by the shift key of the typewriter machine, mechanism as now described may be employed. As shown in Fig. 3, the shift key lever 72 is provided with a lateral pin or shoulder 73 adapted to ride, when the shift key lever is depressed, along a preferably curved face of an upwardly projecting arm 7% of an elbow lever 75 which is pivot ally supported at 76, the other arm of the lever 75 being connected by a link 77 with one arm of an elbow lever 78 pivoted at 79, the lower end of said elbow lever 78 extending along the forward edge of the pivot bar support 69, so that whenever the shift lvey lever is depressed the bar 69 will be oscillated to carry the tongues 36 above the planes of the tops of the levers 31, this movement of course, incidentally swinging the hand lever 71 in the direction of the arrow in Fig. 3. This movement of the shift lever, as usual, permits the upper case characters of the numeral key levers to be printed, but no actuating of the calculating mechanism occurs. The reason for the curvature of the arm '22 projecting from lever 75 is to give an easy cam-like movement while at the same time obtaining the requisite amount of motion to perform the function described.

The numeral key levers of the machine are indicated at 2, the usual slotted guide plate or comb for said levers being indicated at 1. Each key lever 2 is connected to actuate a lever pivotally mounted upon a stationary rod 81. The upper end of each lever 80 is iormed as a fork, the structure illustrated in Fig. 1 comprising a side plate 82 riveted to one side of the upper end of the lever 80 but spaced therefrom sufficiently to admit the lever 2 between said plate 82 and the side of the upper end of the lever 80, said plate 82 having the same configuration as the upper end of the lever 80, this structure forming, as mentioned, a fork for the upper end of said lever. To

preserve the engagement of the parts, a

horizontal portion of the lever 2 so that a catch 87 will partake of all vertical movements of the lever 2. The catch 87 is formed with a teeth 88 and is also formed with a slot, the upper portion of which is substantially vertical as at 89, the lower portion being offset or cam-shaped as at 90 and embracing a rod 91 which extends across between the sides 6 of the frame of the attachment. Mounted in the sides 6 is a rock shaft 92- having arms 93, which arms carry a bar 9-1, the lower front edge of which is shaped as a continuous tooth from one end of the bar to the other, so as to be able to engage either tooth 88 of the catch 87 that has been brought into position for such engagement. The rock shaft 92 is provided with an arm 95, connected by a link 96 with an arm 9'? of a bell crank mounted loosely on the shaft 20, the other arm 98 of said bell crank having a roll 99 adapted to be actuated by a cam 100 on shaft 11.

It will now be understood that each rotation of the shaft 11 causes the earn 100,

through theconnections just described, to

throw the bar 9e downwardly. Since the very first downward movement of a key lever 2 causes the catch 87 to move downwardly enough so that the cam part 90 of the slot in said catch will cause said catch to swing under the rib or tooth edge of the bar 9t, such first movement of the key lever 2 throws its catch to such a position that the rest of the movement of the key lever 2 will be elfec-ted by the power of the motor. Consequently, all that the operator has to do is to depress the key lever 2 sufficiently to slightly move the catch 87 downwardly and shift it into position so that the bar 9 power driven, completes the rest of the operation. Therefore, although the drawings do not show a complete typewriting machine, yet since the mechanism shown is adapted for use when printing numerals, the said mechanism does practically include typewriting mechanism which is power actuated. These connections are such that if for any reason the motor fails to oscillate the bar at so as to cause a lever 2 to make a complete stroke to perform its usual operation, such complete stroke may then be manually completed by the operator. Such movement causes the lever 80 to operate, the same as though the motor had completed the stroke. Therefore, if any catch 87 should break or become worn, the mechanism does not become entirely inoperative. Owing to the vertical portion of the slot 89, the guide rod 91 offers no obstruction to the completion of the stroke of the lever 2 by a manual operation whenever desired.

At the same time that the catch 87 has been swung as described, a pin 101 projecting from the lever 80 moves along an inclined or cam portion 102 of a slot formed in a bell crank 103 pivoted at 104 and having its lower arm formed with a lug 105. Of course there is a bell crank 103 for each numeral key lever of the machine. The lugs 105 co-act with a control plate 106, as hereinafter described. Said control plate is mounted so that it may be shifted slightly trans versely of the machine between a front guide rib 107 and two short rear guide ribs 108, these ribs being carried by a plate 109, the front edge of which is formedby the rib 107, the rear edge being indicated by a dotted line in Fig. 1. The plate 109 is secured to the outer ends of two reciprocating bars 110 (see Fig. 1), said bars 110 being similar to the actuating bars 35. These two bars 110 are reciprocated by levers 111 which are similar to the levers 31. The levers 111, however, at their upper ends, contact with stops 11.2 which are similar to the stop tongues 36, but are fixed instead of being laterally shiftable (see Fig. 2). The levers 111, like the levers 31, are pivotally mounted in the carriage 23, and consequently whenever the' carriage '23 'is'reciprocated, the

plate 109 is also moved forwardly and backwardly. If a lug 105 of the bell crank 103 has been lowered to position, to stop rearward movement of the plate 109, then the latter can only shift toward the left (see Fig. 3) as far as permitted by said lug 105, co-acting with the rear edge of the plate 106. Said rear edge, as shown in Fig. 1, is formed with aplurality of stepped recesses 113. These recesses are of different depths progressively, as indicated in said Fig. 1. l/Vhen the plate is in the lateral position shown in Fig. 1, if the extreme left hand lug 105 is depressed, the plate 106 can only move sufiiciently to actuate a counter 46 to indicate two or to add two. If the next lug 105 were depressed, then the plate 106 can be moved rearwardly far enough so that three will be indicated or added, and so on.

The rearward movement of the plate 106 is effected by the springs 30 through the following connections: As has been described, these springs 30 are connected to the carriage 23, and the latter carries the levers 31, the levers 31 pulling the actuating bars 35 rearwardly to put the latter in proper position for actuating the counters, upon the return of said actuating bars. The forward movement of the carriage and all of the levers mounted therein is efiected by the cam 17 through the connections hereinbefore described, and of course this forward movement is always to the same point. It will now be understood that if the control plate 106 is restricted as to its rearward movement, owing to the positioning of either one of the lugs 105, then the selected lever 31 that is to be actuated by the return movement of the carriage 23, will actuate the proper counter in accordance with the particular lug 105 that has been positioned. The carriage 23 is thus restrained in its rearward motion, and any of the rocking bars 31 carried by the carriage are also limited in their rearward motion, and thus, any actuating bar which becomes operative through a selecting tongue 36, having afforded by its lateral position a fulcrum for said rocking bar, also limits or controls any and all of the indications as to their movements from one to nine.

It will be understood that the recesses 113 of the plate 106 are cut so that their inner ends are stepped, the total width of the recesses at their mouths being considerably wider than the lugs 105. By shifting the plate 106 laterally, different portions of the bottom of the recesses in the plate (or in some portions, the rear edge of said plate) will be brought in alinement with the lugs 105.

The control plate 106 is carried by the frame comprising the plate 109 and its ribs 107, 108, and said frame is mounted for to and fro reciprocation, while the plate 106 may reciprocate laterally. The stepped recesses 113 are so formed that when the plate 106 is in the position shown in Fig. l, which is the position for addition, contact surfaces for the lugs 105 are so spaced opposite said lugs, that slidable movement of the carriage 23 is permitted to count from 1 to 9. If said plate 106 is shifted one step to the right, the portions of the stepped recesses which are then opposite the lugs 105, are distant therefrom to permit slidable movement of the carriage 23 to count the co-elficient of 9 in relation to the key operated to effect subtraction by addition according to a wellknown method. But, as is well known, in this method of subtraction by means of addition, the sum added in subtracting the right hand numeral of the subtrahend must be the co-eflicient of that number with 10, instead of the co-eflicient of that number with 9. The recesses 113, as will be seen, are so formed that by adjusting the plate 106 one more step to the right, portions of said recesses are brought opposite the lugs 105 to permit slidable movement of the carriage 23 to count the co-efficient of 10 instead of 9. It is to be understood that this last shifting of the plate 106 is to be effected only for the operation of writing the righthand numeral of the subtrahend. To effect the lateral shifting of the plate 106, said plate is formed with a slot 114 which receives a pin 115 (see Fig. 1) carried by the inner end of a lever 116 pivoted at 117, and having a flexible extension 118, which rests in a recess 119 in the upper edge of a slide 120 (see Figs. 1 and 5). A spring 121 connects a pin 122 carried by said slide with a suitably fixed point 123 so that said spring has a normal tendency to hold the slide 120 toward the right, and through the lever 116, hold the control plate 106 in the position shown in Fig. 1. The slide 120 is formed with a series of notches 124, either one of which is adapted to receive a cam 125 carried by a lever 126 pivotally mounted on a rod 127.

In practice, as will be described in another application filed by us, there will be a series of cam levers 126, the operation of either one of which in a direction to depress its cam into the proper notch 124 so that the cam will act upon the side of said notch, will shift the slide 120 toward the left, and, through the lever 116, shift the control plate 106 for the performance of subtraction. The inner end of either lever 126, when swung downward, presents a stop opposite one end of a pivoted bar 51 so as to prevent carrying beyond that point. Extending under all of the levers 80, is a bar 128, said bar being mounted in two arms 129 pivotally mounted on the rod 81. One of the rods 129 carries also a depending arm 130 so as to constitute in effect a bell crank lever. The

lower end of the arm 130 is provided with a laterally projecting pm 131 through which passes the light rod 16 hereinbefore described. A spring 132 is interposed between the pin 131 and an enlargement on the end of the rod. pressed, its connected lever 80 is moved downwardly and, owing to the bar 128 and the connections just described, the light rod 16 will be drawn forwardly sufficiently to release the control lever 14; so that the shaft 11 will be free to have its single rotation imparted thereto by the motor. As the-rest of the movement of the key 2 is effected by the power, acting through the bar 9 1. to catch 87, the lever 80 and the arm 130 continue to move, and the spring 132 permits of this movement, without strain upon the light rod 16. i

The shaft 11 is provided with a re-setting 1 cam 183 which acts upon a roll 13% carried by one arm of an elbow lever pivotally mounted on the shaft :20, the other or lower arm 135 of said elbow lever being connected by a link 136 with an arm 137 of a rock shaft 138. The shaft 138 is provided with a series of pins 139 extending downwardly to position to act upon the pivoted arms 51 in a manner presently described. Each arm 51 has a spring 1 10 connected to it and extending to a point so that, when the rock shaft 138 is actuated under the influence of cam 133, all of the pins 139 will re-set the carrying arms 5.1 tonormal position, the springs 140 constituting yielding connections or buffers which we have found in practice facilitates the operation of; thisportion of the mechanism. The cams carried by the shaft 11 occupy such relative positions that. when the parts start from the position shown in Fig. 3, the cam 133 acts to re-set all of the. carrying arms 51 through the connections just described, while theother parts of the machine are performing such movements as.

occur during the rearward movement of whatever rack l is being carried to position to actuate its counter on its return move: vment. In other words, the cam 133 performsits function before the. cam 100 reaches the roll 99.
