4151,5208, liled March 11, 1921. As shown in the drawn gs, there are provided our banks of amoimt keys, each bank consisting of a plurality of keys of different denomination, giving the machine a registering capacity o'l The keys used in this device are of the press down type and are so constructed that it' the wrong key has been depr ssed through error the depression of another key in the same bank will automatically release the first mentioned key; A novel mechanism also provided w iich operates under the control of the depressed keys to break the latch ot the differential mechanism in a position corresponding to the value of the key depressed. t

2 Keyboard.

The machine includes main side frames 18 and 19 (F 1 and. 8) which support the main shafts of the machine. is shown in Figures 1 and. 9, each of the keys 2O is'pivotally mounted on a shaft 21 which is supported by side frames 22 and 23 suitably secured to the base of the machine (not shown). These keys are adapted to be depressed, that is, rocked counterclockwise about the shaft 21, but this movement is limited by means of a rod 24s which extends through slots 25 cut in all 01 the keys (Figs. 1 and The operation 01 the keys is what is known in the art as flexible, that is, the depression of any key in a bank will automatically release any key in the same bank which has previously been depressed. The means for accomplishing this will now be described. Each of the key plates has a notch 26 cut therein. A plate 27 carried by a pair oi arms 28 loosely mounted on a shaft 29 normally lies adjacent the notches 26. There is one or these plates 27 for each bank of keys, as can be seen from Fig. 4;. The arms 28 tend to rock constantly in clockwise direction due to the influence or a spring 30 which is stretched between a pin 31 *arried by an extension. of one of the arms and any suitable point on the base oil the machine. The keys 20 are normally held in their upper position by means ol :1 spring 32 stretched between a pin carried by each key and a rod 33 running across the entire machine and supported by the side frames 22 and 23. it can be seen from the above that when any key is depressed an o, A oonroaarron or transinclined portion 3a thereof will contact with a beveled portion on the upper edge of the plate 27 and as the key is depressed will rock said plate downwardly until the notch 20 comes into alinement with said plate, whereupon the spring 30 will cause said plate 27 to move into said notch and thereby mamtain the depressed key in its depressed position. If, however, any other key in the same bank is depressed, the cam portion Ell thereon will rock the plate 27 downwardly far enough to release the previously depressed key and at the same time engage the notch 26 and hold the key last depressed in its depressed position.

Mechanism is also provided for locking the depressed keys in their depressed positions, as well as locking the undepressed keys in their undepressed positions during the operation of the machine. This function is performed by a yoke carried by a pair of arms 36 faston a shaft 37 which is support ed by the side frames 22 and F23. The shaft 87 is given a counter-cloclnvise rotation (Fig. 1) at the beginning of an operation of the machine in a manner which will hereinafter be described. This n'iovement of the shaft 87 will, through the arms 36, move the yoke 35 into engagement with the notches 26 in the undepressed keys and will. at the same time take up a position just back of a shoulder 38 on any of the keys which have been depressed. This position of the yoke will be maintained until near the end of the operation of the machine and it will therefore positively lock the keys in either their depressed or undepressed positions,

DWI 0mg mec/ z cmi-vm.

This machine is adapted to be driven either by means of a motor of any suitable design or by a crank handle 39 mounted on the right hand side of the machine (Fig. 8). If the crank handle is used to operate the machine, a pinion 40 carried thereby will be meshed with the teeth of a large gear 11 rotatably mounted on a stud 1-2 secured to the side frame 19 of the machine. This gear, in turn, meshes with a gear 13 fast on a shaft 44, which is the main drive shaft of the machine. The gearing just above described is so proportioned that two complete rotations of the crank handle 39 will cause the shaft i to receive one complete clockwise revolution. viewed in Fig. if a motor is used to drive the machine. it is connected to the shaft 44- by mechanism which is well known in the art and which is shown in the above mentioned. patents and application. It is not thoughtnccessarv therefm'c to include any further description thereof hcrei 11.

R076 using wteclmnianz.

As is usual in machines of this type. the

mechanism is normally locked, and manual means are provided for releasing said mechanism for operation. Reference may be made to the copending application of 15. M. bnipley, tlerial No. ($255,027, for a detailed showing of this mechanism. 1f the machine motor-driven the releasingmechanism also closes the motor circuit so that the operation will be commenced immediately. If, however, the machine is operated by the crank, the releasing mechanism must tirst be operated and then the crank handle be given two complete rotations. In order to effect this releasing movement of the machine there is provided a motor bar 4:5 (Fig. 8) which is su iported by a plate 415 having a bifurcated end which straddles two lugs projecting from another plate which, in turn, is supported by two studs 1-9 extending through slots into the side frame 19 of the machine. The plate =18 also carries a stud 51 which projects into the bifurcated end 52 of a lever 53 mounted on a stud 5-1 projecting from the machine side frame. This lever at its opposite end carries a pin 55 which extends into the bifurcated end 56 of an arm 57 loosely mounted on a shaft 58 supported by the machine side frames. The arm 57 is connected by a yoke 59 to a hool-t-shapcd member 60 which is adapted to co-opcrate with a roller (31 carried by an arm (3 loose on a shaft of also supported by the machine side frames. The arm (32 is connected to another arm (54L by a yoke (35 (.llig. 7). The arm ti t at its lower end is formed with three teeth 66 which mesh with teeth (57 carried by a member (.38 loosclv mounted on the shaft 58 and which has it squared end against which normally rests a flat-sided stud carried by an arm 70 which loose on the shaft 63. The arm 70 has a portion 71 which lies over a roller 72 carried by an arm 73 fast on the shaft (33. It can be seen from the above that when the bar is depressed to release the machine the plate 4 8 will he slid inwardly on the studs 49, and the stud 51. which engages w h the bifurcated portion of the lever 53. will rock said lever counter-clockwise about the stud 5 1. This movement will cause the pin 55 carried by the opposite end of said lever, through its engagement with the hil'urzated portion 50 of arm 57, to rock this arm. and through the yoke 59 the hooked portion (it) clockwise. This movement of the hooked portion (it) by means of its engagement with the roller 61 carried by the arm 62 will rock this arm. and through the yoke (35. the arm Li-l clockwise. The arm (51-, through the engagcmcnt of its teeth 66 with the teeth (37 on the member (38 will rotate this member counter-clockwise about the shaft 58 far enough to cause the squared end of the member tiSto pass out of engagement with the fla t side of the stud (39 carried by the arm 70. The shaft 68 constantly tends to rock in a clockwise direction under the influence of a powerful spring 75 (Fig. 8). Therefore, when the arm is permitted to rock in a cl ckwise direction, as above described, the spring 7 5 will cause the shaft 68 and arm 7 8 to rock clockwise and thereby bring the flatsided stud 69 into a position between the member 68 and a member 76 which is loose on the shaft 58 but which is held in engagement with the member 68 by means of a spring 77.

The spring which constantly tends to rock the shaft 68 in a clockwise direction, is compressed between the bottom of a slot 78 in a link 79 (Fig. 8) and a shoulder formed on two members 80 which arepiv-oted to an arm 81 fast on the shaft 68. The stud which forms the pivot of the members 80 is carried by the arm 81 and projects through a slot in the upper end of the link 79. The clockwise movement of the arm 81 and snaft 68 is limited by a stud 88 projecting from the side frame of the machine into the path of movement of a projection 84 integral with the arm 81.

It will be recalled that the yoke is moved into engagement with the notches 26 in the keys to lock the keys against depression and into engagement with the shoulder 88 of said keys to prevent therelease of the depressed keys during the operation of the machine. The means for rocking the yoke 85 to accomplish this function will now be described. Faston the shaft 87 which carries the yoke is an arm 85 to which pivoted a link 86, which at its other end is pivoted to an arm 87 loose on a shaft 88 which is supported by the side frames 22 and 28. The arm 87 is connected by a hub 91 (Fig. to a similar arm 89 to which pivoted a link 90. This link at its upper end is pivoted to an arm 101 which is fast on the shaft 08. It can be seen from Fig. 5 that when the shaft 68 is given its clockwise rock-- ing movement the link 90 will be raised. and through the arm 89, hub 91 and arm 87 the link 80 will be moved toward the right, as seen in this figure. and therefore the arm 85 and shaft 87 will be rocked counter-clockwise a. sutlicient distance to raise the yoke 85 into engagement with the notches 26 in the keys, as above described.

Difl'crentz'al mechanism.

The differential mechanism shown in con nection with this invention is identical with that shown and described in the above mentioned patents and application, and therefore only a very brief description thereof will be included herein. The differential mechanism is driven by means of a pair of cams 102 and 108 which cooperate with anti-friction rollers 104: and 105 respectively carried by a Y-shaped member 106. pivoted to a frame 107 at 1070, which partially supports each differential unit. The frame 107 is supported by rods 108 and. 109 mounted in the side frames of the machine. At its upper end the Y -shapcd member 106 is pivoted to a link 110 which at its other end is pivoted to a driving se ment 111 rotatably mounted on a bushing 112 supported by the frames 107. Also mounted on the bushing 112 is a pair of differentially movable plates 118 between which are mounted actuating segments 11. 1. The cams 102 and 108 are fast on the main drive shaft 1 1 and are given a complete clockwise rotation on every operation of the machine. This movement, through the Y-- shaped member 106 and link 110, causes the driving segment 111 to be given first a clockwise and then a counter-clockwise movement. The plates 118 are connected to the driving segment 111 by means of a latch 99 pivotally mounted on an arm 115 and a bell crank 116 carried by the plates 118. The inner end of the latch 99 engages a shoulder 117 formed on the periphery of the driving segment 111. The latch is norn'ially maintained in its inner position by means of a spring 118 stretched between the upper end of the bell crank 116 and a pin on the hub of the plates 118. The cams 102 and 108 for the various groups of keys are timed to move the actuating segments 111 upwardly simultaneously and to return them to effect transfers successively.

The plates 118 are rotated by the driving segment 111 in a clockwise direction, and in orderto properly add, indicate and print the amounts set up on the keyboard the latch 99 of the differential mechanism must be broken when the plates 118 reach a position corresponding to the value of the key de pressed in their appropriate banks. In order to accomplish this result the following mechanism has been designed.

Each of the keys 20 has a downwardly e7;- tending tail 120 which has formed thereon a shoulder 121. These shoulders are located at different distancesfii'om the upper ends 122 of said tails, depending on the value of its corresponding key (see Figs. 1 and 9). Adjacent each of the banks of keys is an arm 128 pivoted on a shaft 88 having a curved slot 124 formed therein. Projecting into this slot is oneend of a rod 125 (Fig. 1) which is supported by a pair of arms 126 fast thereto. The arms 126 are pinned to a shaft 127 which is loosely mounted in the ends of two arms 128 fast on a shaft 129 supported by the machine side frames. Also fast on the shaft 12! is a downwardly extending arm 181 to which is pivoted one end of a pitinan 182 (Fir 1 and 2). The pitman 182 is slotted at its rear end to receive the main drive shaft ll and carries two anti-friction rollers 188 and 185 which cooperate with a. pair of cams 185 and 136 respectively, fast on the shaft 4a. The shaft 4% is given a complete clockwise ice rotation on each operation of the machine, and through the cams 135 and 186 moves the pitman rearwardly, which movement by means of the arm 131 rocks the shaft 129 counter-clockwise (Fig. 2). As the pairs of arms 128, (each of said pairs being appropriate to one of the banks of keys) are fast on the shaft 129, they will be rocked counter-clockwise (Fig. 1) and will lower the shafts 127, and through the arms 1213 fast thereto will lower their rods 125 in the slots 1241; and then return said rods to their normal positions.

It can be seen from Fig. 1 that the depression of any of the keys in a bank will move its corresponding shoulder into such a position as to obstruct the passage of the rod 125 at a certain point in its travel in the slot 12%. Therefore, when the rod 125 comes in contact with the shoulder 121 it will cause the rod 125 and arms 126 to be rocked clockwise about the shaft 127, and as the end of the rod 125 travels in the slot 12 1 the arm will be rocked counterclockwise with said rod. It can be seen that the rocking movement of the rod 125 will. take place at different times during the downward move ment of the rod, depending upon which one of the keys in its corresponding bank of keys has been depressed.

The arm 123 for the tens of dollars bank (Fig. 3) is fast to the shaft 88. Also fast to this shaft an arm 138 which extends pwardly and at its upper end is bifurcated to co perate with a pin 139 carried by a lever 1 11) which is pivoted to a segmental plate 1 11 supported at its lower end on the rod 109 and at its upper end on a rod L12.

A lever 1 13 similar to the lever 110 is pivoted on the plate 1&1 and has a bifurcated portion 11 1 cooperating with the pin 139. At its upper end the lever 148 is pivoted to a plate 1-15, which plate at its lower end carries a roller 1 1-6 adapted to cooperate witn a bifurcated portion 1%? in the lower end of the lever 1 10. The levers 1 110 and 1413 are held in their normal positions, as seen in Fig. 1, by means of a spring 118 stretched between pins carried by extensions 1419 of said levers.

It can be seen from the above description that when the lever 12 is rocked countcrclockwise, due to the engagement of the rod with the shoulder 1.21 on the tail 1211 of the depre scd key and the subsequent camming action thereof. the arm 123 will impart a counterolm-kwise movement to sha 1'1 88 and arm 136%. This movement, through the cooperation of the bifurcated portion in the upper end of the arm ioS with the pin 139 will rock the lever 1 1O counter-clockwise and the lever 1&3 clockwise simul taneously. As the opposite ends of the levers 1410 and 143 are connected to the plate 145 it can be seen that this plate will more inwardly radially toward the center of the differential mechanism tlfin l). The parts are so timed that as the differentially movable nieu'ibers 11b (airrying the actuating segments 1121: given their clockwise rotation the plate 115 will be moved inwardly ust in time for the appropriate one of a series of notches formed on the inner e( lee of said plate to engage the forward end of the bell, crank 11c and thereby break the latch of the differential mechanism in the position appropriate to the value of the key depressed. ll hen the latch is broken the forward end of the latch member 91) will come into cngagemcnt with one of a series of notches 151 formed in the inner edge of the plate 111. above described. The mechanism above described is for the lens of dollars bank of keys. The means for connecting the arms 123 of the units of dollars, tens of cents and units of cents banks with their appropriate arms 138 can be seen in Fig. -3, and consist of sleeves 1:32 which surround the shaft 88 and are supported thereby.

ll'hen the driving segment 111 upon its counters:lockwise return movement reaches the pos' 11011 at which the latch was broken, the spring 111% will move the latch member 99 rearwm'dly and once more engage said latch with the shoulder 1.1.7 of the driving segment and the differentially movable plates 11?- will then be returned to home position by the cnganenient of a pin 153 car ried thereby with the upper cud of the driv- 111;,2: segment .111.

It will be noted from Fig. 1 that the radially movable plate 1.4;?) has only seven notches cut therein. When the latch is to be broken in the first position the bell crank 1.16 comes in contact with the lower edge of the plate and thereby breaks the latch. \Vhen the latch is to be broken in the ninth position. the plate 1 115 is only partiallv moved, as there no shoulder appropriate to the ninth position on the plate 1151. hen this condition arises the latch will. be broken by the engagement of the bell crank 1113 with a lug); 15 1; carried by the plate 111. In case no key in a bank is depressed. a zero stop pawl 156 is provided. which will break the dill'erci'itial latch in the zero position. This zero slop pawl is normally in position to engi'agle the end o1 an arm 157 projection from a plale (not shown hcrciu) but which can be seen in the liel'orcnicntionwl patents and application. 'lhe end of this plate 15'? is bifurcatml and compcralcs will a pin 15$; projecting lat rally from the end of the bell crank 111$. can therefore be seen thal as the differential mechanism moves in its clockwise direction, the end of the arm 157 will come in contact with the zero stop pawl 1%.

and, due to the engagement of the pin 158 with said arm, will. rock the bell crank 116 and thereby break the latch, as above do ill] loo

scribed. The Zero stoppawl is maintained in its normal position, as shown in Fig. 1, by means of a spring 159 stretched between a pin on the plate 1 11 and a pin carried by an extension of said pawl. If any key in a bank is depressed, the upper end 122 of its tail will give the rod 125 a slight elocln wise movement, which movement will be transmittd to the arm 128, shaft 88 and arm 138, as above described. Each of the arms 138 has a downwardly extending curved portion which norn'ially contacts with a pin 161 carried by a downwardy extending portion 162 of its a ipropriate zero stop pawl. It is therefore evident that as tlie arm 138 is given a' slight counterclockwise rotation upon the depression of any of the keys in its bank, the lower end 166 thereof will also move in a counter-clockwise 'directiornand through its-engagen'ient with the pin 161 will rock the zero stop pawl counter-clockwise out of its effective position.

t is desired on totalizing operations to have all the Zero stop pawls rocked out of effective position, and this is accomplished by means of a rod 168 carried by arms 16-1 fast on a shaft supported by the machine side frames. This sha't 165 is rocked in a clockwise direction by 'niechanisu'i controlled by a movement of the total lever, used in machines of this class, to any of its totalizing positions. This mechanism, tlilOPEli the engagement of the rod 163 with a surface 191 on each pawl, will rock all ofthe zero stop pawls 156 counterclockwise to inerective position.

The segment 170 also has teeth 17 2 formed thereon with which an alining plate 173 is adapted to, cooperate. This alining plate is carried by a plurality of arms 17d fast on a shaft 17 At the beginning of an operation the shaft 175, arms 17-1 and plate 173 are given a clockwise rotation to disengage the plate 173 from the teeth 172. The differential mechanism is then operated, and when it has received its differential movement the alining plate 1'78 is once more eng 'agedwith the teeth 1'72 and thereby prop- :y alines the parts of the differential mechanism. 1

Printer.

At its lower end the liiik169 appropriate to. each difrerential unit is pivoted to an arm 116 which is fast on ashaft 177 or one of a plurality of sleeves 178 surrounding said shaft. 'llh is shaft and the sleeves supported thereby carry at their opposite ends appropr ate type wheels which cooperate with other mechanism to print the amount regis- 111666718 for releasing 7063 3 at Z716 end of an operation.

It will be remembered that the shaft 63 is given a. clockwise movement in order to re the machine for operation by the spring 75 (Fig. 8). It is therefore necessary at the end of an operation to return this shaft to its normal pos 'ion and this object is accomplished in the following 1113112161. Pivoted on a bl nd 180 is a curved arm 181 which carries a pin 1.82 in ta :3 ment with a recess 183 formed in an op IMHO; 18 1 in the link '79. The arm 181 carries a roller 185 which is adapted to cooperate with a cam groove 186 formed in the large gear all, previously described. it will be remembered that this gear is given one-halfof a complete rotation at each operation of the machine. The cam groove 186 is therefore provided with two cam portions 187 which will cooperate with the roller 185 the extreme end of the operation of the machine and thereby rock said arm first clockwise and then counter-clockwise to its normal position. 'Upon the clock wise movement of the arm 181 the pin 182 will move the link 17 9 downwardly, which movement will rock the arm 81 and shaft 6?.

As these indicators form no part of the present inp counter-clockwise a little past normal position. Vi hen this occurs the pin 72 which is carried by the arm 78 fast on the shaft 63 comes in contact with a surface 188 of a restorin member 189 which is loosely mounted on the shaft 58 (Fig. 6) and thereby rocks said restoring member counter-clockwise. This restoring member 189 has a tail 190 which cooperates with an extension of the pin 69 so that when the member 189 is given its counter-clockwise movement, as above described, the tail 190 will rock the arm 7U carrying the pin counter-clockwise about the shaft (33 far enough to permit the spring 7? to return the member (38 to its normal posi tion behind the pin (39. The shaft- 63 is then rocked slightly clockwise to normal and held in its normal position, as shown in Fig. 7. The return movement of the sh aft 63 to nor mal position, through the link 90, arm 89, sleeve 91, arm 87 and link 86 rocks the arm 85 in a clockwise direction (Fig. The arm 85 has a downwardly extending portion 200 carrying a pin 201 adapted to cooperate with. the end of a lever 202 which is fast on the extreme left hand end of the shaft 29. Also fast on the shaft 29 two arms 203 which carry pins 204:. These pins normally lie adjacent to upwardly extending projections 205 carried by one arm of each of the pairs of arms 28 which support the latching! plates 27 for the keys (Fig. at). l/Vhen the arm 85 is given its clockwise movement, as just described, the pin 201 will engage the end of the area 202 and rock this arm counter-clockwise (Fig. 5). As this arm is fast to the shaft 29 this shaft will also be given a conntor-clockwise movement, as seen in Fig. 1. which will. cause the arms 203 to come in contact with the upwardly extending per-- tions 205 of the arms 28 and rock these arms and the plate 2'? carried thereby downwardly out of en gagcment with the notch 26 of the key depressed in this bank. The rocking of the arm 85 in a clockwise direction, as lust :bove des ib-cd, will rock the shaft 3? in the same direction, which movement will cause the arms carrying the yoke member r)\) to be rocked clockwise to remove the yoke member from its engagement with the notches 26 of the undepressed keys and the shoulder 38 of the depressed keys. As both the latching plate 27 and the yoke member 35 are now removed, the springs will return the depressed keys to their normal undepressed positions.
