8 Claims.

This invention relates to improvements in looking mechanism for manipulative devices in accounting machines.

This application is a divisional application of application Serial No. 116,004,,filed by Warren P. Loudon on September 16, 1949, now Patent No. 2,628,774.

The invention is shown applied to a machine of the type disclosed in United States Patents No. 2,209,763, issued to Ernst Breitling on July 30, 1940, and No. 2,587,019, issued to Frank R. Werner on February 26, 1952; and in the copending applications for United States Letters Patent of Frank R. Werner, Serial No. 46,165, filed August 25, 1948, and Serial No. 58,114, filed November 3, 1948.

The principal object of the invention is to provide a machine of the type disclosed in the above-mentioned patents and applications for use by cooperative societies, and, as illustrated herein, the machine is adapted for use in Great Britain, where cooperative societies are well organized and consist of many cooperating stores.

The object of theinvention is to provide an interlock to prevent the adjustment of amountsetting manipulative devices when a special manipulative device is moved into a certain position.

With this and incidental objects in view, the invention includes certain novel features of construction and combinations of parts, a preferred form or embodiment of which is hereinafter described with reference to the drawing which accompanies and forms a part of this specification.

.Of said drawing:

Fig. 1 is a side view of an amount manipulative device.

Fig. 2 is a side view of a special transaction lever. and an interlock actuated thereby.

Fig. 3 is a detail front elevational view showing the side spacing of the amount and transaction manipulative devices, together with the interlock actuated thereby.

General description As disclosed in the parent application, the right-hand half of the machine embodying the invention comprises a set of amount setting levers, a transaction lever, and a clerks lever, together with four machine release keys. In certain business systems, particularly in cooperative stores, as operated in Great Britain, in which members of a cooperative association are entitled to receive rebates, a record is kept of their particularaccounts. If a. customer who is a non-member of the association makes a purchase, it is then desirable to print a code on the perforated strip (illustrated in the parent case) indicating such, so that the data will not be added into an account. In order to control such auditing, a special code is perforated on the perforated strip before the entry of the sale to a non-member is entered into the machine. Setting of the transaction lever to its ninth position controls certain interlocks in the machine, which prevent the adjustment of the amount levers and also prevents operation of a receipt printing and issuing mechanism. Thereafter, upon operation of the machine with the amount levers all set at zero, a code is perforated on the perforated strip adjacent the non-members account number, which account number may represent an account number of another association, and therefore, when the perforated strip is later analyzed, the special code perforated on the strip controls the analyzing machine to skip the entry of the amount which is entered on the perforated strip immediately following the operation in which the code is printed. After the code is printed, the amount of the purchase is set up on the amount levers and the normal operation of the machine is made, whereupon the data is perforated on the strip.

Amount setting manipulative devices Loose on the main shaft 37 (Figs. 1 and 3) is as amount lever 10 for each denominational order, an upward extension of which terminates in a finger piece H, which protrudes through a corresponding arcuate opening in the cabinet of the machine. Each of the levers 10 has a plurality of v-shaped notches 12 cut in a segmental portion thereof. Said notches correspond to the different positions of the levers and are adapted to cooperate with respective rollers it, each of which is mounted upon a corresponding lever 14, loose on a shaft 15 supported by the frames 29 and 30 (Fig. 3). A spring it, connected to each lever 14, urges the levers 14 clockwise to maintain the rollers 13 in engagement with the notches 12, thereby providing a means for locating and retaining the amount levers 10 in set positions. Each of the setting levers is connected by a link ll to a corresponding mechanism for setting an indicator, and each lever is provided with teeth 35 for setting type carriers, and also a stud for actuating a totalizer differential segment in the manner disclosed in the above-mentioned patent to Breitling and in the parent case.

Each of the settable levers it has a segmental portion of gear teeth 85, which mesh with a corresponding drive gear to set a corresponding type wheel.

Transaction setting manipulative devices Adjacent the highest order amount lever 1d, a lever 290 (Fig. 2) is provided for controlling certain functions in the machine, as disclosed in the parent case. When this lever is moved into its ninth position, means are adjusted to lock the amount levers against movement. The lever 280 is provided with teeth for setting type carriers; a link 298, for setting an indicator; and a link Etl, for actuating a control element, all as fully described in the parent case.

Interlock between transaction and amount manipulative devices In the system in which the present invention is illustrated, it is necessary to prevent the recording of amounts on the perforated strip when the transaction lever 2E0 (Fig. 2) is in the lowermost, or nine, position. such aresult, a means actuated by the transaction lever positions a lock in the path of the lever 14 in each amount bank to lock the res'p'ective studs 13 in the notches T2 of the amount lever.

To accomplish this result, the transaction lever 200 is provided with a stud 839, which is moved into the chain-line position when the lever is set into it's eighth position. In this po- 'sition, the stud 830 contacts a lever BSE, and, upon "movement of the lever 2M! into its ninth position, the stud 830 lifts the arm 83% to move around the shaft 31, upon which it is pivoted. The arm 83! is connected to an arm 832 by a link 833. The arm 832 is connected to a sec ond arm 832 by a yoke 834, and the arms 8-32 are pivoted 'on a shaft 2 [8. A spring maintains the arm 832 in lowered position, with a toe 836 o'n'the 'arr'n 832 against a shaft 365. The arms 832 carry a rod 838, which extends across the planes of all the levers 14 of the six amount bank's. When the lever 200 is moved into its ninth position, the rod 833 is lifted into the paths of the lower ends of the levers M, thus locking the studs 13 in the notches of the amount levers, to prevent any movement thereof.

While the form of mechanism shown and described herein is admirably adapted to fulfill the object primarily stated, it is to be understood that it is not intended to confine the invention to the form or embodiment disclosed herein, for it is susceptible of embodiment in various other forms.
