Claims.

This invention relates generally to improvements in cash registers and has particular reference to improvements in the diiierential and printing mechanisms of such machines, and is a 5 division of an application for Letters Patent of the United States of Frederick L. Fuller, Serial No. 161,752, iiled January 18, 1927.

The principal object of this invention is to provide an improved differential mechanism which may be utilized for the purpose of adjusting type carriers and indicators as well as actuating accounting machines. In machines of the type used herein for the purpose of illustration it is considered advantageous and desirable, if not altogether necessary, to provide means whereby the keys during their initial movement may be operated independently of the differential mechanisms. This idle movement is particularly important since it permits other mechanisms to be actuated prior to any registering movement of the differential devices and the time which it allows may be employed for a number of purposes, among which may be stated; the latching of the desired keys to the key coupler, the unlocking of the differential actuators, the engagement of a totalizer with the actuators, etc. Moreover, in respect to the printing functions of the machine, it is desirable that the adjusted type carriers be retained in their differentially adjusted positions when the keys have completed their downward strokes so that printing may be properly effected at this time.

Prior to the present construction, it has been the practice to provide the cam slots which cooperate with members operated by the keys with dwells at each end of the cam slots. This permits an idle movement of the keys at the beginning and end of their strokes for performing the desired functions. It is the purpose of the present invention to dispense with the dwells and to provide a mechanism whereby the cam slots may be continuous so that immediately upon the movement of the member which cooperates with the cam slot the differential actuators will be moved.

In the present construction in order to provide for the idle movement between the keys and the diiferential actuators, the member which cooperates with the cam slotted element, has a pin and slot connection with the related key, the parts being so arranged and designed that each key may be operated initially without eiiecting any movement of its cooperating member. For the purpose of illustrating and describing the 55- -utility of such devices this mechanism is shown in connection with devices whereby the keys may be latched to the key coupler during their initial movement at the same time that the actuator locking devices are released. The differential actuators are shown in connection with printing 5 mechanisms whereby they may be utilized for the purpose of differentially adjusting the type carriers as well as the accounting elements.

In respect to the printing mechanism of the machine it is also an object to provide a simple and effective printing mechanism whereby the items may be printed upon a record strip as well as to provide a simple and effective mechanism for printing of the totals upon the record strip. Among the many features embodied in the iml5 proved printing mechanism may be mentioned, an improved paper supply frame which may be bodily elevated from its normal position whereby access to the paper supply may readily be had. Furthermore, in respect to the improved paper feeding devices, the latter are so arranged that during the down stroke of the keys a portion of the paper is drawn from the storage roll thereby rendering a certain amount of slack in the paper. During the return stroke of the key and after the items have been printed the slack is taken up by winding the paper upon the storage roller. Thus by dividing the paper feeding movements between the strokes of the keys the hard operation which would result otherwise is reduced to a great extent.

In the accompanying drawings the improvements are shown applied to a machine of the same general type as is shown and described in the United States application, Serial No. 263,125, i'lled November 19, 1918, by Frederick L. Fuller, and issued January 7, 1930 as Patent No. 1,742,701; and British Patents Nos. 135,465, 140,363, 157,823, 157,824 and 157,825 of July 14, 1921, covering the same inventions. However, as will be more clear- 40 ly apparent later on, the inventive ideas are capable of being embodied in a variety of mechanical structures, and it is to be expressly understood that the drawings are designed for the purpose of illustration only, and not for the purpose of elements of which are set forth in appended claims and a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form a part of this specification.

General construction The machine taken for the purposes of illustration is provided with a number of operating keys divided into denominational groups and if so desired special keys may also be included, but

for the purpose of the present invention these need not be described. The amount keys 24 are all pivoted upon a transverse shaft 25 which is carried by the framework of the machine, this shaft forming the pivotal point of the keys which are guided in their reciprocating movements at their forward ends by slots 26 formed in a cabinet 2l and at their rearward ends by slots 28 formed in a plate 29 attached to a portion of the framework 30. Each of the keys 24 is formed with a square notch 3| adapted to receive the flange 32 of thekey coupler 33 when the latter is elevated by a depression of any of the operating keys. The key coupler is pivoted at 34 between the side frames of the machine and, as will be noted, the

pivotal points of the shaft and key coupler are displaced with respect to each other so that the flange 32 of the key coupler will intersect an arc described about the key shaft as a center and passing through the forward end of the upper shoulder forming the notch 3|. This is for the purpose of coupling the keys so that a complete depression of a single detached key will result in a simultaneous depression of all the keys which have been attached to the key coupler in a manner to be described hereinafter.

Connected to the key coupler 33 is a plate 35 carrying two sets of oppositely disposed rack teeth 36 which are adapted to alternately engage the teeth of a pinion 3l fast to a driving shaft 38 which is also suitably journaled in side frames of the machine. The connection is such that when the key coupler is rocked by the keys the rack 35 is raised and lowered so that the reciprocating motion of the key coupler will be converted into a rotary motion of the shaft 38. The device for accomplishing this need not be described herein in further detail as this sort of mechanism is well known in the art and shown in many patents. For details of construction and operation of one form of the above, reference may be had to the patent to Thomas Carney, No. 482,461, dated September 6, 1892.

In nearly all forms of cash register construction it is considered desirable that after a registration has commenced some devices be provided to compel a complete performance of the started registration before a second operation can be effected. To this end there is secured to the main operating shaft 38 (Fig. 2,) a ratchet wheel 39 against which bears a spring-pressed pawl 40 for preventing any retrograde motion of the shaft 38 and thus insuring a complete operation of the machine when once started.

Dierential mechanism In machines of the class described, the operating keys usually have associated therewith a differential mechanism whereby the keys may differentially adjust type carriers, actuate totalizing mechanism, and control the displaying of indicators so that full information relative to the keys operated may be available in various forms. The machine as herein disclosed is provided with a novel form of differential mechanism which will now be described in detail.

As will be noted in Fig. 1, each of the operating keys 24 is provided with an extension 4| directly over the key shaft 25. It will also be observed in Fig. 3 that each key 24 is pivotally mounted upon a collar 42 which is loosely mounted on the shaft 25, the collar 42 having rigidly attached thereto an upwardly extending arm 43 carrying a pin 44 in engagement with a circular aperture 45 formed in the extension 4| of the key, it being noted that the aperture 45 is slightly larger than the diameter of the pin 44 which projects therein and that each arm 43 is mounted adjacent its respective key 24. Each arm 43 is provided with a roller 46 in engagement with a cam slot 41 of an associated cam plate 48. The cam plates 48 of which there is one for each key are arranged in groups and those of each group fit in slots formed in a frame 49 loosely pivoted upon a transverse shaft 50, the plates 48 being secured to the frame by cross pins 5|. It will be noted from Fig. 1 that the cam slots 4l of the various plates 48 are eccentric with respect to the key shaft 25 so that as each key of a group is depressed its roller 46 coacting with the cam slot 4l of its related cam plate will rock the frame 49 differentially an amount commensurate with the key depressed. 'I'hus it will be understood that when a key of the lowest value in a group or bank is depressed the associated cam plate 48 and differential frame will be rocked a unit amount,

whereas when keys of a greater value are op-` erated the frame 49 will be rocked a greater amount depending on the value of the key operated.

'I'he construction of the differential devices as explained is such that a key may be given a movement independent of the plate due to the loose connection 44, 45 between the key and the arm 43.

It will be obvious that when the key 24 is slightly7 depressed it will elevate the key coupler 33 to a corresponding extent. As will be observed in Fig. 1, there is slidably mounted upon the key coupler 33 a latch plate 52 which is urged rearwardly by a spring 53, suitable stop devices such as shown in the Fuller Patent No. 1,742,701 and British patents mentioned before being provided whereby movement of the latch plate beyond the position shown in Fig. l is prevented. When a key is initially depressed the rack plate 35 will be raised thereby rotating the shaft 38 a partial amount and as the ratchet wheel 39 rotates the spring-pressed pawl 40 will engage one of the teeth of the ratchet wheel adjacent one of the open spaces 54 (Fig. 2). This cooperation will prevent retrograde movement of the key coupler and the shaft 38 and it will be understood constitutes the means for holding the key coupler in its partially elevated or coupling position.

Each bank or group of keys has associated therewith a latch plate 52 so that each latch plate may be operated independently of any other latch plate.

Whenever the key coupler has been raised to its coupling point the latch plates 52 mounted on the coupler will be slightly above the notches 3l formed in the rear ends of the keys which have not been operated, and will bear against the concentric edge 55 of such keys. When it is desired to attach an amount key to the elevated key coupler the desired key is depressed slightly resulting in the raising of the rearward end of the key and by virtue of the concentric edge 55 cooperating with the rear edge of the latch plate 52 the latter will be forced forwardly until the concentric edge clears the latch plate 52. At this time the latch plate will be free to be moved rearwardly under the influence of the spring 53 to engage the notch 3| formed in the rear end of the depressed key. In this manner the amount key is positively engaged or attached to the key coupler and in the same manner amount keys associated with the other banks may be partially and successively depressed so as to latch them to the key coupler which then permits a simultaneous completion of the depression of all the keys which have been so attached.

It is considered desirable during the time that the keys are being latched to the key coupler that there be no movement of the differential devices and that during this time the differential devices which are normally locked, be unlocked to permit their subsequent actuation by the keys. This timing element also permits engagement of a selected totalizer with the differential devices.

Referring to Fig. l, it will be noted that one of the cam plates 48 of a group is provided with a projection 56 cooperating with a hook 51 formed as an integral part of a bail 58 which extends underneath the keys of a bank and which bail is loosely mounted upon the shaft 25. A spring 59| is provided to urge the hook 51 into locking relationship with the projection 56. During the time that a key is being initially depressed the underside of the key coacting with the bail 58 will rock the bail downwardly, thus disengaging the hook 51 from the projection 56, and since the key will be held in its initially depressed position this relationship will be maintained.

As will be observed in Fig. l, when an amount key 24 is partially depressed for the purpose of initially operating the key coupler or latching the key tothe partially elevated key coupler, the extension 4l will be rocked about the shaft 25 and due to the fact that the engagement of the roller 46 against the upper edge of the cam slot 41 is sufficient to hold the arm i3 from movement temporarily against any frictional force existing between the coacting sides of the arm 43 and the key 25, the key 24 may be operated independently of the arm. When the key has been initially depressed to coupling position the rearward edge of the aperture 45 will coact with the pin 44.

As the depressed keys are operated still further the rear edge of the aperture 45 coacting with the pin 44 will rock the arm 43 of the depressed key ciockwise about its pivotal point, and since the roller 46 coacts with the cam slot 41 of its respective cam plate the frame 45 will be rocked differentially and during this time the rollers 46 associated with the undepressed amount keys in the same bank will play in the arcuate slots 59 formed in the related cam plates 48 which permit the upward tilting of the differential frame 49 without interfering with the rollers carried by the unoperated keys.

The differential movement of the frame 49 may be utilized for many purposes and as herein shown is utilized to adjust item type carriers and actuate totalizer elements. Connected to each differential frame is a segment 6i) which, as shown in Fig. 4, is in engagement with a pinion 6l rigidly secured to an item type carrier 62 journaled upon a fixed shaft 63. As stated, each differential frame has secured to it a corresponding segment 56 so that when the segments are moved by the depression of the keys in the related banks the item type wheels 62 will be rotated correspondingly and, as will be described hereinafter when suitable impression means are actuated the item type wheels will print characters indicating the amount of the transaction entered in the machine.

Printing mechanism The printing mechanism. for printing the items comprises a printing frame formed of two side frames 55 and 65 (Fig. 6) which are connected together by a cross bar 61 at the rear ends, and by a rod 68 (Fig. 1) at their forward ends. Each of the frame members 65 and 65 is provided with claws 66 (Fig. 7) overlying the shaft 5D. The forward parts of the side frames 65 and 65 rest upon a tie bar 16. The frame members 65 and 65 are also connected together by shafts and other members which will be referred to hereinafter.

Secured to a shaft 1l (Fig. 4) which is carried by the frames 65 and 66 are two rearwardly eX- tending arms 12 and 13 (Fig. 6) which are connected by a cross head 14 carrying a rubber impression block or platen 15 overlying the item type carriers 62. Pivotally mounted on a stud carried by the frame member 65 is a bell-crank 16 (Fig. 8) which, as shown in Fig. 4, is provided with a roller engaging the race of a box cam 11 secured to the driving shaft 36. The bell-crank 16 has a pin and slot connection with a second bell-crank 18 (Fig. 8) one arm of which is bifurcated to receive a pin carried by a downward extension 16 of a clutch member 66 (Fig. 6) which is springpressed along the shaft 1l by means of a spring 85E. The clutch member 66 is adapted to form the connecting means between the platen and the operating parts of the machine and is provided with a forwardly extending arm 8i (Fig. 7) to which is connected a spring 82 which normally urges the platen 15 upwardly away from the type.

During the downward movement of the keys the item type carriers will be adjusted differentially and during the time that the type carriers are in their differentially adjusted position the box cam 11 (Fig. 4) will move through an angle of substantially 180 degrees, thereby bringing the cam position thereof into proximity with the roller carried at the rear end of bell-crank 10. As the operated keys start their return movement the extensions 4| are moved a short distance independently of the stud 44 and the differential mechanism is held in its adjusted position during this interval. t is then that the cam portion of box cam 11 will rock bell crank 18, extension 19, and clutch member 80, and consequently platen 15 will be rocked downwardly against the adjusted type carriers, thereby effecting a printing impression upon the record strip. Continued restoration of the keys will serve to restore the arms 43 to their normal positions thereby allowing the differentially operated frames to drop to their normal positions. It will be understood that since the forward edges of the apertures 45 will be in engagement with the stud 44 during the return stroke of the keys that the arms 43 will all be positively returned to their normal positions.

Printing from the type carriers is effected upon a record strip 83 which is drawn from a supply roll 84 (Fig. 4) and wound upon a storage roll 85. The supporting studs for the rolls 84 and 85 are attached to a frame member 88 (Figs. 6 and 7) which is loosely mounted upon the platen supporting shaft 1|. As best shown in Fig. 4, the record strip 83 is drawn from the supply rcll 84 over a roller 81 carried by the frame 86 thence rearwardly around the platen 15 over the cross bar 14 and thence forwardly over a roller 88 also carried by the frame 86, and then is wound upon the storage roll 85.

In order to feed the record strip an increment after each printing operation, the following mechanism is employed. Attached to the driving shaft 38 is a box cam 90 (Fig. 7) the race of which cooperates with a roller carried by a bellcrank 9| pivoted upon the side frame 55. he forward arm of the bell-crank 9| is bifurcated to engage a pin 92 (Fig. 8) carried by a toothed segment plate 93 loosely mounted upon the stud which forms the supporting means for the supply roll 84. The teeth of the segment plate S3 engage teeth formed on a second segment plate 94 loosely pivoted upon the supporting stud for the storage roll 85. The plate 93 carries a feeding pawl 95 in engagement with the teeth of a ratchet wheel 9B connected to the supply roll B4 while the segment plate 94 carries a feeding pawl 91 in engagement with the teeth of a ratchet wheel 98 connected to the storage roll 85.

During the downward stroke of the keys the bell-crank 9| will be rocked counter-clockwise (Fig. 7) so that its forward end will be raised thereby rocking the segment plate 93 counterclockwise (Fig. 8) and by the engagement of the pawl 95 with the teeth of the ratchet wheel 9B the supply roll 84 will be rotated slightly so that a portion of the record strip will be unrolled. During this time the segment 94 will be rocked in a clockwise direction (Fig. 8) so that the feeding pawl 91 will slip over the teeth of the ratchet wheel 98. During the return stroke of the keys the forward arm of the bell-crank 9| will be rocked downwardly and since the segment member 94 will be rocked counter-clockwise the feeding pawl 91 will rotate the storage roll 85 in such a direction that it will wind onto the storage roll that portion of the record strip that has been unrolled from the supply roll and thus bring the printed portion of the record strip around the cross head and to such a position that it may be viewed through a glass carried by a lid 99 (Fig. 4) hinged to the cabinet of the machine. 'I'he glass is provided with a writing slot |00 through which written entries may be made in juxtaposition to each printed item, the cross bar 14 serving satisfactorily as a writing table` The inking mechanism for the item printing mechanism of the illustrative machine comprises an inking ribbon |0| (Fig. 6) which is drawn from a roller |02 (Fig. 1) over the printing type carriers and then onto a receiving roll |03 (Fig. 6). The inking ribbon |0| is supported over the type carriers by a pair of plates |04 (Figs. 4 and 6) which are suitably apertured so as not to interfere with the printing action of the platen 15. Any suitable mechanism may be provided for giving the inking ribbon a step by step movement during successive operations of the machine, and since this mechanism forms no part of the present invention, it will not be described in the present application.

It will be noted in Figs. l and 7 that the printing mechanism is normally entirely concealed by the lid 99 and another lid |05 which is also hinged to the cabinet 21. It is necessary at times to obtain access to the printing mechanism and particularly the paper supply devices in order to replenish the supply of paper when exhausted and for this reason the frame 86 which carries the paper supply and storage rolls is so mounted that it may be swung about shaft 1| as a pivot, as shown in Fig. 7, to render the parts accessible.

When the paper carrying frame is returned to l" its normal position it is latched by means of a latch member |06 (Fig. 1) engaging a lug |01 formed on the side frame 65.

Situated just forward of the item type wheels 52 and adapted to engage the segmental racks 60 are pinions |08 attached to the printing wheels of a pair of totalizers designated as A and B in Fig. 4. Both totalizers are pivotally mounted so that by suitable mechanism the totalizer frames may be rocked about their pivotal points to bring the totalizer pinions into and out of engagement with the actuating racks 00 so that the totalizers may accumulate the items entered in the machine. The totalizers may be utilized for the purpose of registering amounts for separate departments or clerks and to this end any suitable selective totalizer engaging mechanism may be utilized. Since this feature is not directly involved in the present application it is not herein shown or described but for one form of mechanism which may be employed for this purpose reference may be had to the Fuller Patent No. 1,742,701 and British patents hereinbefore mentioned.

It is desirable to print the totals accumulated by the totalizers so that there may be provided an unalterable record valuable for future reference. It is also desirable to have this information printed directly upon the itemized record strip and to this end it is a purpose of the present invention to provide a simple and effective total printing means. Secured to a shaft |09 (Fig. 4) extending between the side frames 65 and 60 is a platen carrying frame ||0 carrying a plurality of platens overlying the printing wheels of their respective totaliaers. It will be noted that the record strip passes just beneath these printing platens while interposed between each platen and its related printing wheels is an inking ribbon ||2 (Fig. l) which is guided and supported by spaced 75 supporting plates H3 (Fig. 4) and carried at its ends by a pair of spools. Any suitable devices may be utilized for manually feeding the inking ribbon from one spool to the other when the impressions become light. Secured to the shaft it@ is a printing lever l i4 (Fig. 6) the lever being so arranged that when it is moved one way one of the platens will force the record strip and inking ribbon against the printing line of one totalizer and when moved in the opposite direction the other platen will effect a printing impression upon the record strip from the other totalizer. After this has been performed it is desirable to manually feed the record strip so that the printing impressions may be brought to view and to this end there is pivotally mounted upon the stud which carries the storage roller $5 a lever H5 (Fig. 8) carrying a pawl H6 in engagement with the ratchet wheel 98. By suitably reciprocating the paper feeding lever H5 the printed record strip may be fed manually so that the impression may be brought to view. As best shown in Fig. l, the paper feed4 ing lever projects through the lid Q9 so that it may be exteriorly operated, this being also used for feeding the record strip an additional amount when the space provided by the usual feeding of the record strip by the machine is not sufficient to accommodate the desired autographic notation.

If so desired any suitable locking devices may be provided to lock the printing lever so that printing operations by unauthorized persons may be effectively prevented.

While the type of differential mechanism illus-- trated in Figs. l and 3 has been found practical and capable of performing the results described very effectively, it is to be understood that this is but one embodiment of the invention and that other specific methods and mechanisms may suggest themselves for accomplishing the same object.

One modification of the present invention is illustrated in Fig. 5 'wherein it will be noted that the extension il in this oase is pivotally secured by a pin II'I to the arm #13, the lower end of the arm being provided With an aperture i ifi slightly larger than the key shaft 25. Therefore, it will be obvious that a lost motion connection between the key and the arm 43 is produced through the enlarged aperture H3 encircling the shaft 25. When a key employing this type of construction is depressed the extension iii will be rocked clockwise and due to the fact that the roller Mi is held against movement by means of the cam plate the pin IH will rock the lower end of the arm d3 forward until the rearward edge of the aperture I I8 coacts with the periphery of the key shaft This movement of the key independently of the roller 4G is sufficient to latch the key to the coupler and to perform other functions such as unlocking the differential actuators, selecting a totalizer for operation, etc. It will be obvious that the lost motion connection is also effective at the beginning of the return stroke of the keys so that the type carriers will be held in their adjusted positions while printing from these type carriers is being effected.

In describing the construction of the mechanism comprised by the improvement it has been necessary incidentally to give a thorough explanation of the operation of the different devices. llt is thought, therefore, that the usual summary of operation may, in this case, be omitted.

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.
