10 Claims This invention relates to improvements in cash registers and accounting machines and has more particular reference to that class which are adapted to issue checks or tickets having amounts printed thereon commensurate with the value of the keys depressed, and is a division of the application for letters patent of Herman F. Sadgebury, Serial No. 137,664, filed Sept. 25, 1926, now Patent No. 1,957,671, dated May 8,

Machines of the class operable by a crank or electric motor are usually equipped with a printing mechanism which serves satisfactorily to print and issue checks during operations of the prime mover. The devices utilized to perform these functions include parts which are usually heavy and rugged, and, therefore require considerable power to operate. The feeding devices usually comprise a pair of feeding rollers which are geared to the prime mover, the check paper being usually inserted between these rollers so as to feed the check out of the machine. Moreover, the devices utilized to print and sever the check comprise heavy parts which in themselves require considerable power to operate. Attempts have been made in the past to apply to machines of the key-operated class the same type of printing mechanism employed in key-set machines, with the result that such machines were hard to operate and in order to overcome the hard operation auxiliary power devices were usually added, which in themselves, were complicated, and apparently did not solve the problem of attaching a check-printing mechanism to key-operated machines.

The principal object of this invention is to provide a check printing mechanism for a keycperated machine so that all the functions incidental to check printing and issuing may automatically be performed by a manual depression of the keys without sacrificing speed of operation and requiring but a slight additional load upon the keys.

In order that the key-operated'machines to which the improved printing devices are applied may be operated with a minimum of time and expenditure of energy it is an object of the invention to provide a novel paper feeding device which is positive in its operation and requires little power to operate. In the illustrative embodiment of the invention this comprises a pair of normally separated reciprocating members which, during their initial movement, are adapted to positively grip and hold the paper so that upon a continued operation of the machine the check Will be fed to the proper point.

In connection with the novel paper feeding devices embodied in the illustrative machine, it is also an object to provide improved devices whereby the paper strip will be caused to be fed in substantially a straight line either during manual feeding operations or during feeding operations performed by the machine. This overcomes to a great extent the disabling of the machine which usually occurs when printing mechanisms are jammed by the accumulation of check paper caused by the natural curl of the paper. The improved machine employs a very simple device for counteracting the natural curl of the paper.

The arrangement of the printing attachment is such that the roll from which the checks are drawn is visible, and in front of the operator, so that he will readily know when the supply of paper has been exhausted, and the design is such, furthermore, that a new roll of paper may be readily inserted by those unfamiliar with mechanical devices and within a minimum of time.

Due to the peculiar and advantageous arrangement of the paper feeding devices the check paper may be readily inserted in the printing mechanisms and when it is desired to discontinue check issuing, the paper may readily be withdrawn since it is accessible and visible to the operator. However, by the employment of a special manipulative device with which the illustrative machine may be provided, a more convenient means of discontinuing issuing of checks may be afforded.

In the accompanying drawings the invention is shown applied to a cash register such as that fully illustrated and described in the U. S. Patent to Frederick L. Fuller, No. 1,742,701, January 7, 1930. The invention is not limited in its application to any one particular kind of machine but is capable of application by various modifications to accounting machines in general.

With these and incidental objects in view the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which will now be described with reference to the drawings which accompany and form part of the specification.

Detail description The amount keys I (Fig. 2) are loosely pivoted upon a key shaft II so that they may be moved through an angle about said shaft as a pivot. The amount keys I0 are guided in their movements at their forward ends by slots formed in a cabinet I3, and at their rearward ends by slots formed in a plate I4 which is attached to a portion of the framework. Resting upon the rear ends of the keys is a key coupler I provided with trunnions I0 by which it is pivoted, and with a flange 'I'I coacting with notches I8 formed in each of the operating keys. The key coupler serves in the usual way to insure simultaneous and uniform depression of the keys.

The key coupler is provided with a pin I9 extending through a horizontal slot 20 in an upright double rack member 2I. The rack has a slot 22 embracing a fixed pin 23 and is thus guided in its vertical movement by the pin, but is rocked around the pin so that the sets of teeth 24, 25 carried by the rack member 2| will alternately engage a pinion (not shown) attached to the main driving shaft 26 of the machine.

The devices for printing and issuing checks are, in the main, carried by two side frames 41 and 48 (Fig. 3). The side frames are connected together in spaced relation by shafts and cross members so that most of the elements comprising the check printing devices may be carried by said framework. These side frames and the parts carried thereon may be readily detached from the machine for the purpose of inspection, adjustment, etc.

The checks which are issued are drawn from a check roll 92 (Fig. 1) the paper being wound upon the usual form of spool 93. The check roll receptacle comprises two side plates 94 and 95 (Figs. 1 and 5) between which is extended a curved plate 00 which is bent so as to form a curved paper guiding plate 91. The members just referred to may be connected or attached to each other by any suitable means so as to form an integral unit and in the illustrative machine the unit is attached to the printer frame by screws 98 which pass through the plates 94 and 95 and into the side frame 4? (Fig. 1).

Secured by screws 99 (Fig. 5) between the side frames 41 and 48 is a block I00 which is undercut at I0! (Fig. 3) to a width substantially the width of the check strip. As best shown in Fig. 1 the check strip passes under the curved plate 91 and between the block I00 and the plate I02 which is provided with an integral rearwardly extending portion I03 curved and bent at its sides to form a paper guide or chute.

The check roll 92 is held in its proper position by means of spring grippers I04 (one only being shown Fig. 1) which are riveted to the side plates 94 and 05 and are formed with concave depressions I05 which project through apertures in the plates 94 and 05 to engage apertures formed in the ends of the spool 93. By this means the roller may readily be placed in the container or detached therefrom. By the present construction the engagement between the concave depressions I 05 and the ends of the spool 93 creates little frictional resistance when the check roll is rotated as the paper is fed by means which will now be described.

The paper feeding devices for the illustrative machine comprise an eccentrically mounted disk I06 (Fig. 1) cooperating with lugs I 0'1 integral with a pitman I08 which is attached by a pin I09 to an arm IIO loosely mounted upon the shaft 21. By the mechanism just described the arm H0 is given a reciprocating movement during each operation of the machine.

Attached to the check printer side frame 48 by means of studs III (Figs. 3 and 4) is a guide plate II2 which is formed with a slot H3 in which projects a stud II4 carried by a plate H5 and another stud II 0 also carried by the plate H5. The plate II 5 has also attached to it a stud II 7 (Fig. 1) engaging an open-ended slot formed in the arm IIO, the stud being suitably recessed so as to receive a spring H8. The spring II8 also fits in a cup shaped member II9 (Fig. 3) which is attached to a plate I20 by an upwardly extending stud I 2I the plate being loosely pivoted on the stud H4. The stud I2I is upset at one end to attach the cup II9 to the plate I20. The stud I2I has secured to its upper end a gripping member I22.

The spring II8 normally tends to force the gripping member I22 upwardly but is prevented by means of a bell-crank I23 (Fig. 1) loosely mounted on the plate II 5, the bell-crank being formed with a hooked portion engaging a shoulder I24 formed in the lower part of the plate I 20. In order to disengage the hooked portion from theplate I 20 at the desired time there is provided a second bell-crank I25 loosely pivoted upon the shaft M and having a hooked portion I20 engaging an extension of the bellcrank I23. The bell-crank I25 is urged by a spring I21 so that its rearward arm engages a stud 49. As best shown in Fig. 4 the plate I20 is provided with a stud I28 projecting through an aperture formed in the plate II5, the stud I28 being adapted toengage a shoulder I29 formed on the guide plate II2 when the plate H5 is shifted.

As best shown in Fig. 3 the check strip is located between the gripping member I22 and a cooperating gripping member I30 which fits in a recess formed in the block I 00 and is slidably mounted in the block I00 by means of a stud I32 fitting in a slot I3I (Fig. 5). In order toinsure that the gripping member I30 may receive the same movement as the associated gripping member I22 there is provided a bail or yoked member I33 pivoted to the block I00 by means of a stud I34. The free end of the upper portion of the bail is forked to receive the stud I32 (Fig. 5) which carries the gripping member I30 and its lower portion (Fig. 3) is bifurcated to receive the stud I 2I attached to the gripping member I22. The gripping surfaces may be comprised of rubber or any other suitable material so that at the desired times they may grip the check paper and feed it forwardly, the operation of the above described mechanism being as follows:

When one of the keys is depressed the shaft 26 will be rotated and the arm I I0 will be rocked to the right as viewed in Fig. 1 and since the bell-crank I25 will hold the lower end of the bell-crank I23 against movement as the plate II5 is moving forwardly continued movement of the plate H5 and the plate I20 will cause the bell-crank I23 to rock clockwise (Fig. 1) to positively disengage the hooked portion of this bellcrank from the shoulder I20 of the plate I20. This will permit the spring II8 to raise the gripping member I22 to positively grip the check paper between it and the associated gripping element I30. Further depression of the keys will move the plate I20 and the gripping members still further forwardly and their gripping action upon the check paper will positively feed the latter over the adjusted type carriers.

When the keys reach their extreme downward movement a printing impression is effected. At about this time the stud I28 cooperating with the shoulder I29 will rock the plate I20 clockwise as viewed in Fig. l, permitting it to be again latched by the bell-crank I23 whereby the two gripping members are separated. During the return movement of the keys the arm, IIO will be moved in a reverse direction and when the plate I20 reaches its extreme rearward movement the bell-crank I25 will again engage the bell-crank I23, the parts then being in the position shown in Fig. 1. It will be obvious that since during each operation of the machine the gripping members grip the check paper at substantially the same time and feed it similar amounts the successively issued checks will be of a uniform length.

In some machines equipped with printing devices considerable annoyance is caused the oper ator when a new supply of paper is inserted in. the machine primarily due to the fact that on account of the natural curl of the end of the check paper the strip tends to deviate from the proper course. The result of this is that the operator is required to spend considerable time in threading the paper strip and to obviate this difficulty the illustrative machine is provided with a simple and effective device.

Attached to the underside of the plate I02 is a pair of forwardly extending springs 2I6 (Figs. 1 and 3) which are suitably bent so as to leave an opening between the underside of the block I00 and the top of the spring to permit the passage of the check paper between. The ends of the springs underlie the extreme forward end of the block I00 which end is machined so as to form a curved extension 2I'I (Fig. 1). When the end of the check strip is passed into the chute 96I and forced forwardly the natural curl of the paper, would, if no means were provided to prevent it, tend to pass upwardly and possibly behind the platen. With the provision of the curved extension 2H and the springs 2I6 when the end of the check strip passes between these elements the curl of the paper will be counteracted with the result that the check paper will pass straight forwardly beneath the platen and over the inking ribbon. In the event that the end of the check strip should strike the platen it will strike a beveled portion 2I8 (Fig. 1) of the casting I45 so that it will be directed downwardly to the proper position. It is to be understood'that this construction does not only function during manual feeding operations but also during the feeding operations of the check strip by operations of the machine.

When it is desired, as is often the case in some lines of business or under certain conditions to use the machine without the check printing attachment, the check strip may be simply withdrawn from the chute and reinserted in the same way when it is desired to renew the issuing of checks.

In the illustrative machine this can be performed in a very facile manner since the cooperating feeding elements are normally separated as well as due tothe simple and effective devices which have been provided for guiding the check strip. As a more convenient means for throwing the paper feeding device out of operation and into operation at will, there may be provided a check controlling lever 2I9 (Fig. 4) The lever is pivotally mounted by means of a stud 220 and extends upwardly through a slot in the cabinet I3 of the machine so as to be adjustable to either a check or no check position. The position shown in the drawings is the one it assumes when it has no control over the paper feeding devices and therefore permits them to operate in the usual manner. However, when it is desired to discontinue check feeding without withdrawing the paper strip from the machine the lever 2I9 may be forced rearwardly so that a shoulder 22I cooperating with the stud 222 attached to the bell-crank lever I25 will rock the bell-crank counterclockwise thereby disengaging the hooked end I26 from the extension of the bell-crank I23. Loosely mounted upon the shaft 8| and urged upwardly by a spring 223 is a detent plate 224 having a lug provided with an aperture 225 which cooperates with the lower end of the lever 2I9 when the latter is moved to the no check position. It is to be understood that since the hooked portion I20 is entirely disengaged from the bell-crank I23 the latter will not be tripped during an operation of the machine thus permitting the paper gripping elements to remain disengaged so that they will not be operative to feed the check paper.

Summary of operation A resum of the general operation of the machine will now be given to coordinate the operations and functions of the various parts which have been described in detail.

It will be assumed that the operator desires to issue a check for the amount of 20. In the illustrative machine to issue a check commensurate with this amount it is only necessary to depress the appropriate key and permit it to return to its normal position, the various functions of check issuing, printing and severing being performed during this cycle of operation.

When the appropriate key in the dimes bank is depressed the notch I8 (Fig. 2) in the rear end of the key will engage the flange I? of the key coupler and since the coupler is connected to the rack plate 2| the latter will be elevated and by the alternate engagement of its rack teeth 24 with the pinion attached to the driving shaft 26 it will give the latter a complete operation.

Assuming that the check strip is properly located between the associated gripping members it will be obvious that when the: key is depressed the cam I06 (Fig. 1) co-operating with the lugs I01 will rock the arm IIO forwardly and since the bell-crank I25 will hold the lower end of bell-crank I23 against movement as the plate I I 5 is moved forwardly, the continued movement of the plate H5 and the plate I20 will cause the bell-crank I23 to rock clockwise to positively disengage the hooked portion of the bell-crank I23 from the shoulder I24 of the plate I20. This will permit the spring II8 to raise the gripping member I22 to positively grip the check paper between it and the associated gripping member I30. The gripping action upon the check paper occurs at substantially the initial movement of the keys so that further depression of the keys will feed the check paper over the type carriers.

When the supply of paper is exhausted which is readily noted, due to the fact that the paper roll projects through the hinged cover 2I3, the spool 93 (Fig. 1) around which the check paper is rolled is withdrawn from co-operation with the spring-urged fingers I04 and a new roll placed therein. The end of the check paper is then passed into the chute 96I between both paper feeding elements, forwardly over the type carriers and beneath the rubber impression block I46. The machine is now conditioned for further printing and issuing of checks.
