, ing application, Serial No. 590,373, filed Septem- 5 coupled to a keycoupler '31 in the usual manner.

ber 25, 1922, (now Patent No. 1,824,248, issued September 22, 1931) of which this is a division.

An object of this invention is the provision of means for operating a machine of the key-operated type from a source of power other than a key. 7 I

Another object of the invention of this application is the provision of mechanism for operating a universal key detent by depression of either of two machine releasing keys which connect either the item entering and item printing mechanism or the total printing mechanism to the source of power.

Another object of this invention is the provision of means for looking out the total key by a partial operation of the universal key detent upon depression of an amount key.

With these and incidental objects in view, the

invention consists in certain novel features of construction and combinations of parts the essential elements of which are set forth in appended claims and a preferred form of embodiment of which is hereinafter described with ref- ,erence to the drawings which accompany and form part of this specification.

In said drawings:-

Figs. 1A and 13 comprise a plan view of the machine with parts omitted.

Fig. 2 is a transverse section through the machine looking toward the right.

Fig. 3 is a detail view showing the mechanism for releasing the motor and driving the key coupler during item entering operations.

Fig. 4 is a detail view showing the mechanism for releasing the machine and driving the printer during total-taking operations. 7

The machine comprises a plurality of groups of amount keys, at totalizer, item entering and item printing mechanism, total printing mechanism, driving means, and keys for connecting the driving means with either the item entering and item printing mechanism or the total printing mechanism. The printing mechanisms are not disclosed in this application.

The keyboard comprises a plurality of groups or amount keys (Figs. 1A, 1B and 2) and item control key 21 (Figs. 1A and 3) and a total control key 22 (Figs. 13 and4). The amount keys 20 "comprise, two members, a front manipulative member 23, and a rear member 24 adapted to be Both members are pivoted upon a rod 19 mounted in the side frames of the machine. The item control and total control keys are mounted upon the ends of the rod 19 projecting through said side frames.

In machines of this type, the members 23 and 24' generally heretofore have been integral to drive the key coupler by depressing the keys. In this machine, the manipulative member 23, is depressed only a slight extent, and this slight movement thereof functions'to stretch a spring 25 (Fig. 2) secured to the frame and to a lever 26 pivoted to said member and provided with a pin 27 projecting over said member and in engagement therewith, into the plane of a forward extension 28 of the member 24.

After a manipulative member is depressed, spring pressure will be exerted on the extension 28 of its corresponding rear key member to urge the rear end thereof toward the key coupler. As the key coupler is raised, the rear key member is also raised independently of the front key member 23 by the spring 25 a suficient distance to effect a I coupling connection with the key coupler.

Uprights 34, connected to the rear ends of the rear key members, are provided with notches for engaging rods 36 carried by rocker members controlling totalizer actuators 37, the notches being located to transmit amounts of movement to the actuators proportionate to the number of units represented by the appropriate keys. The actuators 37 and their respective rocker members are operatively connected together.

The totalizer actuators are normally in mesh with gears 38 which are connected with the item printing wheels (not shown) to set up the amounts represented by the keys depressed.

The right hand end of the key coupler is provided with a trunnion 56 extending through the printer frame.

The amounts represented are also entered in a totalizer mounted in a frame 66 (Fig. 2) pivotally supported in brackets projecting rearwardly from a front cross member 68 and secured'to the side frames. The totalizer is in all respects the same as that shown in the Von Pein patent referred to.

The amount accumulated on the totalizer is ascertained by a printing operation. For this purpose mechanism is provided for setting up total type wheels (not shown) in accordance with the amount in the totalizer, This mechanism comprises stepped disks 86 rigid with gear wheels 8'7 meshing with the gears '71 rigid with the totalizer pinions, and feelers 96, all constructed by the keys depressed and operating as in the Von Pein patent referred to.

The driving means preferably comprises a motor of the usual type (not shown) which drives a clutch shaft 151 (Fig. 4). Mounted on the inner end of this shaft 151, is a gear 152 (Figs. 1B and 4) in mesh with a gear 153 secured to a shaft 154 supported in the main right hand frame 155 and a bracket 156 secured to the motor casting.

Freely mounted on the shaft 154 is a cam disk 160 which cooperates with a roller 161 (Fig. 3) on a pivoted arm 162 connected by a link 163 with an arm 164 secured to the key coupler trunnion 56. The cam disk is provided with a female clutch member 165. Also freely mounted on the shaft 154 is a gear 166 (Fig. 1B) in mesh with a gear 167 secured to the total printing drive shaft 108. The gear 166 is provided with a female clutch member 168.

The means for causing the cam disk 160 and gear 166 to rotate with the shaft 154 comprises the female clutch members on the disk and gear and a sleeve clutch member 169 (Figs. 1B and 4) slidably, but non-rotatably, mounted on the shaft 154 and provided with male clutch end portions to couple with either of said female clutch members.

Normally the sleeve clutch member is held in engagement with the clutch member by means later referred to. In this position, it drives the key coupler for an itemizing operation. When it is desired to print a total accumulated on the totalizer, the sleeve clutch member is moved to the right into engagement with the clutch member 168. This is effected by the total key 22, which will be described later.

Interlocking and control features When the amount key members 23 are depressed, they set up a spring pressure against the rear key members 24 to select them for operation. The key members 23 are held depressed temporarily by spring-controlled angle plates 170 (Figs. 1A, 1B and 2) which snap over projections 171 thereon. There is one plate 170 for each group of keys. These plates are supported by arms of levers 172 rotatably mounted on a rock shaft 173. The lower ends of these levers bear against pins carried by arms 174 pinned to the rock shaft 173. The plates 170 are normally held in the position shown by springs secured to the lower ends of levers 172 and to a rod carried by the frame of the machine. The shaft 173 extends through the right hand side frame where it is provided with an arm 175 (Fig. 3) controlled by a lever 176 freely mounted on a control shaft 180, later referred to. By means of the lever 176, depressed keys may be released before an entry of items is eifected to make corrections in the amount set up.

A look lever 184 (Fig. 4) releases the motor when moved counter-clockwise by a spring 185 and arrests the motor when moved clockwise by an arm 186 rotatable with the shaft 154.

The spring 185 is connected to the frame and to a slidably mounted link 187connected to the arm 184. The link 187 is normally held in the position shown in Fig. 4 by a spring-actuated laterally directed fin 194 in alignment with the lip 191. This catch member is also provided with a shoulder to cooperate with the stud 189. When the catch member 192 is moved downwardly, the catch 188 is released and the lock lever 184 is moved to releasing position. When the lock lever is returned to locking position, the parts move back to the position shown in Fig. 4. A tension spring 196 holds the catch against the stud 189.

The releasing mechanism described may be controlled from either the item control key 21 or the total control key 22. The control shaft 180 is mounted in the side frames of the machine. Adjacent to its left end it carries a rigidly fixed arm 200 (Fig. 3) provided with a pin 201 extending under a bearing edge 202 on the item control key. The key and arm 200 are held in home position by

springs

203 and 204.

Secured to the shaft 180 adjacent to the right hand side frame of the machine, is an arm 205 (Fig. 4) which carries a pin 206 projecting through a plate 207 pivoted on the catch memher 192 at 208 and slotted as shown, to receive the stud 193 on which the catch member 192 is supported. The total control key 22 (Fig. 4) carries a pin 209 for engagement with the plate 207 from which it is spaced when in its home position. The key 22 is normally held in home position by a spring 210 connected to a long stud 211 on the key and to the frame.

When the item control key or total control key is depressed, the control line 180 is rocked to move the catch member 192 downwardlyto release the motor. When the motor releasing mechanism is returned to home position, the

springs

204 and 210 return the control line and total key to home position.

The clutch sleeve 169, before described (Figs. 1B and 4), is normally controlled from the total control key 22, which isnormally held in home position by the spring 210. The key is provided with an arm 215 connected by a link 216 with an extension 217 on a yoke 218 whose side members are mounted for rocking movement on the sleeve clutch member 169. The yoke 218 is held thereon by a sleeve 219 located between the side members of the yoke and connected to the sleeve clutch member by any suitable means 220. The base of the yoke 218 is convex and is provided with a cam groove 221 cooperating with a fixed stud 222 carried by the frame of the machine. By means of the mechanism described, the sleeve clutch member 169 is normally connected with the key coupler driving clutch member 165, and

upon depression of the total control key, is moved into engagement with the clutch member 168 for the total printing mechanism.

It is desirable to prevent an operation of the total control key after an item entering operation has been begun by the depression of an amount key. For this purpose, the amount keys are provided with cam portions 230 (Fig. 2) which cooperate with a universal locking member 231 supported by arms 232 secured to the control shaft 180.

When an amount key is depressed, the control shaft 180 and pin 206 (Fig. 4) are rocked in a clockwise direction a sunicient distance to swing the upper end of a pawl 233 under the stud 211 on the total control key. The amount key is held in this position by the temporary locking plate 170 (Fig. 2). This rocking movement of the shaft 180 is not sufficient to release the machine for operation, such release being subsequently effected by the depression of the item control key 21.

When the item control key 21 is depressed, the control shaft 180 is rocked from the position to which it is set by the depression of an amount key 20, to carry the locking plate 231 over projections 240 (Fig. 2) of amount keys depressed and under projections 240 of amount keys not depressed, and releases the motor for an item entering operation. It is necessary to provide the release key 21 to release the machine, instead of depending upon the depression of an amount key 20 to rock the shaft 180 a suflicient distance to efiect such release, since if the depression of any amount key 20 were to rock the shaft 180 far enough to release the machine, the flange 231 would be rocked beneath the projections 240 of all the undepressed keys 20. Then, it would be impossible to depress another amount key to complete the entry of an amount of more than one digit. Rocking the shaft only slightly by the amount keys 20 locks out the total control key, in the manner hereinbefore described, and after all the amount keys 20 have been depressed, the item control key 21 is depressed to release the machine. When the motor releasing mechanism is returned to home position, the pawl 233 is returned to home position by a spring 241 connected thereto and to the total control key 22.

The total control key may be depressed after an item operation is completed or at any time when no amount keys are depressed. When the total control key is depressed, it first connects the sleeve clutch member 169 with the clutch member 168 to drive the total printing mechanism. The control line 180 is then rocked to lock out all of the amount keys. This movement of the control line rocks the pawl 233 over the stud 211 carried by the total control lever holding the lever depressed until the total printing operation is completed. When this operation is completed, the total control lever will be released, and the clutch sleeve member 169 will be returned to home position by the spring 210.

The key members 23 are also provided with portions 250 for cooperation with plates 251 pivoted on a cross frame member 252 to prevent a simultaneous depression of a plurality of amount keys in the same denominational group.

Operation An item of a transaction is entered in a totalizer and printed on an issuing strip by first depressing amount keys representing the item and then subsequently depressing the item control key. After each of the items of a transaction has been entered and printed, the total control key is depressed to operate the total printing mechanism, which prints the total of the items involved below the items, feeds the printed total past a severing knife, and clears the totalizer to prepare it for a subsequent transaction.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form or embodiment herein disclosed, for it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.
