General description Machines of the type to which the present invention is shown applied, and which are shown and. described in the above mentioned patents, are pro'videdwith a plurality of banks of amount keysand a plurality of departmental or transaction keys. In order to enter a transaction in the machine, it isneces- Sary to depress the amount key corresponding tothe amount of the transaction, and-the transaction or departmental key for selecting" a totalizer into which the amountis to be added. Sometimes the operator fails'to depress the amount keys and when the machine is operated nothing is added in the totalizer. In order to call the attention of the clerk to his failure to depress the amount key, an interlock is provided so that it is necessary to depress not only a departmental key but also an amount key before the machine can. be released for operation.

In machines of the type to which this invention is applied, a No-Sale key is usually provided. When the machine is operated with the No-Sale key depressed, it is apparent that no amount key should be depressed. In order to permit operation of the machine with the No-Sale key depressed,

mechanism is novided so that upondepres' sion of the No-Sale key, the means for preventing operation of the machine releasing mechanism is rendered ineffective.

When the Nobale key is (lGPI'QSSGXLdt is desirable to have the amount keys locked against depression, and when the amount keys are depressed, to have the hie-Sale key locked against depression. Such an interlock is provided between the amount key banks and the No-Sale key.

When atotal is taken from any of the departmental totalizers, it is also necessary to render the machine releasing mechanism'effective without depressing an amount key. A device, ogerated upon moving the total lever out of its add position, is provided for rendering the latches for the releasing shaft ineffective.

Detailed description The machine is provided with a release shaft 30 (Figs. 1, l, 9 and 10). Before the machine can be operated the shaft 30 must be released to be rocked in a clockwise direc tion (Fig. 10) by a spring 31. The method of releasing the machine is described in the above mentioned Shipley patent. One end of the spring 31 bears against a shoulder on a link 32 and the other end against shoulders on two guides 33, pivoted on a stud; carried by an arm 84-, secured to the release shaft 30. The release shaft 30 is retained in its normal position by a release pawlST (Fig. 1 1) which lies in the path of a half-round stud 35, carried on an arm 36 secured to the release shaft 31). The stud normally held in engage ment with the end of the pawl 37 loosely mounted on a shaft 38. The pawl 3.7 is rocked out of the path of the stud 35 when the motor bar 39 is depressed. The motor bar is removably mounted'on a slide 40 provided with a stud engaging the bifurcated end'of a lever 41, pivoted on a stud 42. The slide 40 ismeunted on two studs 43 projectii. from the side frame of the machine. The lever 41 is provided with a stud which projects into a bifurcated arm a4 also pivoted on the shaft 38. The arm 44. is integral with an arm 45, which is normally held in engagement with a stud 46 by a spring l7 connected to the lever 41. The stud 46 is mounted on an arm 48, connected to an arm 49, bifurcated to engage a stud on the pawl 37.

When the motor bar 39 is depressed against the tension of the spring 47, the arm 49 is rocked clockwise (Fig. 11), thereby aising the pawl 37 away from the stud 35. .Vhen the pawl 37 is thus removed from the stud 35, the release shaft 30 is free to be rocked in a clockwise direction under the action of the spring 31, thereby causing the machine to be released in a manner Well known in the art.

Before the shaft 30 can be rocked to release the machine, a latch (Figs. 5 and 9) n'iust berocked away from an arm 56, secured tothe shaft 30. The latch 55 is disengaged from the arm 56 when any one of the ainount keys is depressed, or'by the No- Sale key. The means for withdrawing the latch 55 by the amount key is described first. Each amount key 57 4).carries a stud which projects from each side of the key and co-opcrates with a cam edge 59 of a settable bar 60.. The bar 60 is carried at its lower end by an arm '61 and at its upper end by an arm 62 (Figs. 8 and 9) pivoted to the key frame 63. The arm 62 is provided with a stud 64 which co-operates with a two-armed lever 65, pivoted on the shaft 38. One of the arms of the two-armed bail 68 is rockedin clockwise direction. The

bail 68 is integral with an arm 69, at its left hand end (Fig. 9) and with an arm 70 at its right hand end. The arm 69 is provided with a stud 71, which projects into the bifurcation of an arm 72, loosely mounted on the shaft 38, and which is hubbed to the latch A spring 73 (see also Fig. 5) stretched between a stud on the arm 69 and a stud on the arm 72 normally maintains the latch 55 in the path of the arm 56. The spring 73 also maintains all of the studs 66 in engagement with their respective levers 65. Thus it is seen that wh n any one of the amount keys s depressed, the latch 55 will be moved out of the path of thearm 56, thus permitting the release shaft 30' to be rocked under the influence of the spring 31, as above described.

Each bank of amount keys is provided witlra flexible detent bar 80 (Figs. 3 and it) provlded w th hook shaped detents which are moved into engagement with the studs 580i the depressed amount keys aspring 81, stretched between a stud in' the key frame 63 and a stud on the detent bar The detent bar is pivotally supported by an arm 82 at its upper endand by an arm 83'at its lower end.'

Each bank of amount keys is provided with the usualand well known zero stop pawl 84, each pawl being secured to aseparate shaft 85 journaled in the lower end of its keybank. Also secured to each shaft 85 is a. bell crank 86, provided with a stud 87, held in engagement with the arm 61 by a spring 88. When an. amount key is depressed and the settable bar 60 is loweredby engagement of the stud 58 with the cam edge 59, as above described, the arm 61 is rocked clockwise, thereby rocking the bell crank 86 counter-clockwise, and in this manner causing the zero stop pawl 84 to move to its ineffective position. The zero stop pawl forms no part of the present invention and therefore no further mention thereof will be made'herein.

A second latch (Figs. 1, 2 and 9) is provided, which co-operates with an arm 96, for preventing operation of the release shaft 30 until a transaction key or the No- Sale key has been depressed. The transaction keys 97 are mounted in akey frame 98 (Fig. 1) and are provided with studs 99, adapted to engage the cam edges 100 (Fig. 9) of a settable bar 101. The bar 101 is pivotally supported by an arm 102 at its upper end and by an arm 103 at its lower end. The arms 102 and 103 are pivoted in the key frame 98. The arm 102 is provided with a stud 10 1 which engagesan arm 105, connected to the latch 95 by a bail 106;

\Vhen the transaction key is depressed the bar 101 will cause the arm and latch 95 to bc'rocked counter-clockwise thereby moving the latch out of the path of the arm 96 and thus permitting the machine to be released.

From theabove' description it can be seen that before the motorbar 39 can release the machine, both the latches 55 and 9 5 which are operated by the amount keys and the transaction keys. respectively, must be rocked to their ineffective positions, so that'the shaft 30will be free to rock under the action of the spring 31 (Fig. 10) as before described.

' The transaction bank is also provided with a detent bar 80, like detent bar 80 in the amount bank, for holding the transaction keys in depressed positions. Inasmuch. as this detent bar is identical with the detent bar in the amount banks, no further reference thereto will be made herein.

)Vhen the No-Sale key (Figs. 1, and 9) depressed. both the

latches

55 and 95 are rocked to their ineffective positions so that the machine can be operated without'depressing an' amount key, or-anyof the transaction keys. The No-Sale key 115 is pro vided'with along stud 116, which projects toward the right far enoughto engage the cam edge 117 on a segmental bar 113 carried by an arm 114 integral with a pivoted arm 118 c'a-rriedby a stud 119. The studs 99 on all the other transaction'keys are short studs which are not longenough to cooperate with the cam edges on the bar113. The bar 113 is provided with a cam edge 117 for'the position of each keyso that the No-Sale key can be located in any one of the nine positions and still co-operate with the arms 11 t and The arm 118 (Figs. 4 and 9) is provided with a cam edge 120 which co-operates with a stud 121 of an arm 122,'secured to a shaft 123. The arm 122 is also provided with a stud 124, which engages an arm 125 connected with an arm 126 by a bail 127. The arm 126 is provided with a stud 128 which engages the arm 70 integral withthebail 68. Thus it is seen that when the No-Saie key is depressed, the bail68 will be rocked in clockwise direction by the arms 114,118, 122, 125 and 126. The clockwise rotation of the bail 68 around the shaft30 will rock the arm 72 and latch 55 counter-clockwise to disengage the latch 55 from the arm 56. I

The stud 116 also projects toward the left of the key 115 and engages the settable bar 101. Thus when the No-Sale key is depressed, the bar 101 will'be lowered to disengage-the latch95 from the'arm 96 in exactly the same manner as the. transaction keys 97 disengage the latch 95 from the arm 96 From the above it is apparent that when the .No-Sale key is depressed, the machine can be released by the main motor bar, without the depression of an amount or transaction key.

The arm 118 is held in position with the cam edge 117 in engagement with the stud 116 by a spring 129 (Figs. 1 and 9). \Vhen the No-Sale key is depressed, the arm 118 is rocked against the tension of the spring 129, so that when the bar 101 is lowered, in a manner to be hereinafter described, for releasing the keys, the spring 129 will again rock the arm 118 to its normal position. The movement of the ar1n118 to its normal position, will permit the spring 73 to rock the latch 55 into the path of the arm 56 and will permit a spring 130 secured to the bail 106 to rock the latch 95 into the path ot the arm 96. Tl'lus at the end of the operation of the machine. the

latches

55 and 95 will again be in their latching positions, with their respective arms 56 an'd'96.'

)Vhen the No-Sale key is depressed, a bail (Figs. 7 and 9) is'rocked into the path of the arms 61, thereby preventing depression of any amount key-after the No-Sale key has beendepressed. Secured to the arm 114 is a downwardly projecting arm 136, cmbracing a stud 137 mounted on an arm 138 pivoted on a rod 139. The arm 138 is connected to an arm 140 by a bail 141. A stud 142 on an arm 144 is held in enga ement with the arm 140 by a spring 143 fig. 7). The arm 144 is connected to an arm 145 by the bail 135. The

arms

144 and 145 are loosely mounted on a shaft 146. Secured to the bail. 135 (Fig. 7) is an arm 147 also loosely mounted on the shaft 146. The arm 147 is provided with a stud 148 with which one end of the spring 143 engages. The other end of the spring 143 engages an arm 149 secured to the shaft 146. The spring 143 normally holds the stud 148 in engagement with the arm 149, thus maintaining the bail 135 in its normal position, in which the stud 142 is held in engagement with the arm 140, as shown in Fig.7 9.

When the No Sale key isdepressed and the arm 114 is rocked in a counter-clockwise direction (Fig. 9) the arms'138 and 140 are rocked clockwise, thereby rocking the bail 135 downwardly into the path of the arms 61. This movement will cause the spring 143 'to be tensioned because the arms 149 and shaft 146 are held'stationary at this time and therefore the stud 148 will be moved away from the arm 149. However, when the No- Sale isreleased at the end oft-he operation of the machine, the spring 143 will again rock the arm 147- counter-clockwise until stopped by engagement of the stud. 148 with the arm 149. This will return the bail 135 to its nor 'mal position, in which the arms 61 will be free to be moved by depression of an amount key.

After an amount key hasrbeen depressed, the No-Sale keywill be locked out against depression. lVhen the amount key is de pressed, the arm 61 is rocked beneath thebail 135, and therefore, will prevent movement of the bail 135. It is apparent from the above that so long as the-bail135 isf-heldf against movement the arm 138 and consequently the arm 114 cannot'be moved by the No-Sale key, and therefore,the No-Sale key will be held against depression; 1 7

From theabove it is apparent that the bail 135 acts as a means for preventing depression of an amount 7 e after the No-Sale key has been depressed, and also as a means for pre nailing deprcssimi of the No-Sale key after an amount key has been tie/ nfected.

Kcf/ rc/ca-s'c vacclzrnnianz.

As previously stated. near the end of the (narration of the machine, the amount and transaction keys are permitted to return to their normal positions. Secured to the'shaft 30 (Fig. is an arm 150, which is rocked into engagement with the rearwardly'projecting portion of the arm 82 near the endof the operation of the machine. Theshaft-3O is rocked by a cam race 151 ig. 10), which rocks an arm 152 pivoted on a stud 153. The arm 152 is provided with a stud 154, held in engagement with shoulder of the link 32. The downward movement of the arm 152 will cause the link 32 to be lowered, thereby rocking the arm 34 and the release shaft 30 in a counter-clockwise direction, which movement will rock the arm' 150 (Fig. 3), into engagement with the arm 82, as above described. The engagement of the arms 150 with the arms 82 will cause the detent bars 80 in the amount and transaction banks to be lowered far enough to disengage the hook portions of the detents from the studs on the depression keys, thereby permitting springs (not shown) to return the keys to their outer or normal positions.

-The cam race 151. (Fig. 10), is cut int-he side of a gear155, which is given a one-half rotation during each adding operation by a pinion 156. given two rotations by a crank well known in the art but not shown herein.

During total taking operations a total control lever 160 (Fig; 12) controls the machine so that it will make two cycles of operation instead of one, for controlling the machine in a manner well known in the art. During total taking operations the link 32 (Fig. 10) is controlled so that the arm 152 is ineffective for rocking the releaseshaft 30 at the end of the first cycle of operation of the machine and it is again effective to rock the shaft at theend of the second cycle of operation of the machine.

The total control lever 160 is provided with a cam slot 161 which engages a stud mounted on an arm 162. pivoted on a stud 163, and is connected to another arm 164 by a flexible connection in the form of a spring 165. The arm 164 is provided with a cam slot 166 into which pro jects a stud on an arm 167 secured to the shaft 146. Also secured to the shaft 146 (Fig. 10) is an arm 168, connected to an arm 169 by a link 170. The lower end of the arm 169 is pivoted to a link 171, slidably mounted on a stud 172. The rear end of the link 171 is provided with a. stud 173 which projects into a slot of the link 32. Movement of the total control lever 160 will cause the link 171 to be moved toward the left (Fig. 10) far enough to disengage roller 174 from a notch in the cam 175 and more it into the cam race 176. v

The cam 175 is stationary during adding operations, but when the link 171 is moved toward the left for total taking operations, as just described, the cam 175 is coupled to the gear 155, and therefore, during total taking operations the cam 175, is rotated.

The link 171 is provided with two studs 177 between which projects a flange 1780f a coupling slide17 9, normally in arecess 180 in the rear of the cam 175. Movement of the The arm 162 is.

inseam link 171. will therefore cause the slide 17 9 to be moved toward the left until the forward end thereof enters a notch 181 in thegear 155. Therefore, when the gear 155 is rotated, the cam 17 5 will be rotated therewith. i

The cam race 176 is so timed that before the arm 152 is lowered at the end of the first cycle of a total taking operation, the link 17 2 is moved toward the left far enough to posi: tion the long portion of the slot 182 in the link 32 into the path of the stud 154. Thus when the arm 152 is lowered, the stud 154 will move in this long portion of the slot and therefore will not lower the link However, near the end of the second cycle of op: eration, before the arm 152 is again lowered by the cam race 151, the link 171 is again moved to the right (Fig. 10) by the cam race 176. This movement is enough to position a shoulder 183 into the path of the stud 154.

\Vhen the arm 152 is lowered near the end of the second cycle of a total taking operation, the link 32 will be lowered by the stud 154 striking the shoulder 183, thus releasing the transaction keys in the same manner as described for the adding operation.

When the link 32 restores the shaft 30 to its normal position, as just described, the release pawl 37 (Fig. 11) is again rocked into the path of the locking stud 35, thus again locking the machine. Release of the keys will also permit the

respective latches

55 and 95 to again rock into the path of the members 56 and 96. 7

During total taking operations the transaction total is printed by depressing the selected transaction key after the total control lever has been moved to its selected total position, and thereafter releasing the machine. Thus it is apparent that during total taking operations it is necessary to rock the latch 55 (Fig. 9) to its inefl'ective position-because no amount keys aredepressed. Machines of the type disclosed are sometimes provided with group totalizers, and when it is desired to print the total of a group totalizer no transaction key is depressed, because the total control lever selects the totalizer. Since no transaction key is depressed it is necessary to also rock the latch 95 to its inefiective pos tion. Movement of the total control lever out of its add position rocks latches 55 and 95 to their ineffective positions. The total control lever is provided with a cam slot 190 (Fig. 12) into which projects a stud 191 mounted on an arm 192. Movement of the totalcontrol lever 160 in either direction out of its add position will rock the arm 192 in a clock.- wise direction, thereby rocking the shaft 123 to which the arm 122 is secured. The clockwise movement of the arm 122 will rock the arm 125 (Figs. 2, 6 and 9) in a counter-clockwise direction. The counter-clockwise move? ment of the arm 12 5,through the

arms

126, 70,

6 9 and 72, will disengage the latch 55 from the arm 56 in a manner before described.

The arm 125 is also provided with a stud 193 which engages the latch 95. Thus, when the arm 125 is rocked by the movement of the total control lever out of its add position the stud 193 willcause the latch 95 tobe diseng d from the arm .96.

nring total taking operations it is desirable that the amount keys be locked against depression. .As previously stated, when the total control lever 160 is moved out of its add position, the shaft 146 (Fig. 12) is rocked in a clockwise direct-ion by the cam slot 161. The clockwise movement of the shaft 146 will cause the arm 149 (Fig. 7) to rock the bail 135 into the path of the arms 61 of all the amount keys, by theengagement of the arm 149 with the stud 148. As above described, the stud 148 is mounted on the arm 147 se cured to the bail 135. Thus, it is seen that so long as the total control lever is out ofits add position, the bail 135 is in the path of the arms 61, and therefore, no amount key can be depressed.

Operation Before the machine can be released for adding operations, an amount key and, a transaction key must be depressed. Depression of the amount key will disengage the latch 55 from the arm 56 (Fig. 9). Depression of a transaction key releases the latch from the arm 96. After these two latches have been disengaged, the release shaft 30 is free to move to release the machine upon depression of themain motor bar 39. However, when the No-Sale key is depressed, it is desirable to have the machine release without depression of an amount key. Depression of the No-qale key rocksv out both of the

latches

55 and 95, thereby permitting the main motor bar to release the machine.

- Depression of a Noale key will also lock out the amount keys by means of the bail 135 which is rocked in front of the arms 61, which. are moved upon depression of an amount key.

Depression of an amount key prevents dcpression of the No-Sale key, \Vhen an amount key is depressed, the arm 61 of the bank in which the key is depressed moves into the path of'the bail 135, thereby preventing depression of the No-Sale key.

Movement of the total control lever out of the add position withdraws both the

latches

55 and 95 from the path of the arms 56 and 96 of the release shaft, thereby permitting the machine to be released by depressing the main motor bar 39, thus, making it unnecessary to depress an amount key and a transaction key.

In a normally locked machine, the combination of a normally locked releasing mech anism; means to unlock said mechanism; amount keys; transaction keys; a special key; a plurality of devices to prevent an effective operation of the unlocking means unless both an amount key and a transaction key are op amount keys to pr vent operation of the latter when said bail is shifted out of normal position; means cooperating with one of said devices "to render said device ineffective; a rocking bail intermediate said one device and the other device to render the latter device ineffective upon operation of said one de vice; means operated by the special key to erated; a shiftable bail cooperating with the h prevent an effective operation of the unlock- H ing means; a shiftable bail cooperating with said amount keys to prevent operation of the latter when said bail is shifted out of normal position; means cooperating with one of said latches and adapted to move the same to anin'eifective position; a plurality of rocking bails intermediate said one latch and the other latch to render said other latch ineffective when said one latch is moved into an 'inefl'ective lever operated by the special key, to actuate position; and means, including a j said cooperating means; a second shiftable bail cooperating with the first-named shiftable bail; and means on said lever to shift the second shiftable bail to operate the firstnamed shiftable bail to move the latter into an effective position simultaneously with the movement of the latches to their ineffective positions.

8. In a normally locked machine, the combination of a normally locked releasing mechanism; amount keys; transaction keys; a plurality of means for preventing operation of the releasing mechanism adapted to be rendered ineffective by the amount keys and transaction keys; a special key; and a plurality of shit'table bails operated by said special key, certain of said bails to render said preventing means ineffective, thereby permitting the releasing means to operate without first depressing an amount key and a transaction key, other of said bails to simultaneously prevent depression of the amount keys.

9. In a normally locked machine, the combination of a normally locked releasing mechanism; amount keys; transaction keys; a plurality of means for preventing operation of the releasing mechanism adapted to be rendered ineffective by the amount keys and transaction keys; a special key; a plurality of shiftable bails operated by said special key, certain of said bails to render said preventing means ineffective, thereby permittin the releasing means to operate without rst depressing an amount key and a transaction key, other of said bails to simultaneously prevent depression of the amount keys; and means operated by any one of the amount keys and adapted to be moved into the path of said other bail to prevent depression of the special key after an amount key has been depressed.

In testimony whereof I affix my signature.
