  • TRANSFER RESTORING MEANS Filed July 24, 196'? INVENTOR DALE L. PLACKE 7" HIS ATTORNEYS United States Patent 3,441,211 TRANSFER RESTORING MEANS Dale L. Placke, Dayton, Ohio, assiguor to The National Cash Register Company, Dayton, Ohio, a corporation of Maryland Filed July 24, 1967, Ser. No. 655,650 Int. Cl. G06c 7/10 U.S. Cl. 235-433 4 Claims ABSTRACT OF THE DISCLOSURE Cross reference to related application Programmable Totalizer Control Mechanism, United States patent application Ser. No. 618,598, filed Feb. 27, 1967, by Louis E. Zurbuchen and Freeland R. Goldammer.
  • the invention is directed to a mechanism for restoring tripped transfer mechanisms in a positive manner.
  • Prior devices have used springs to restore the transfer mechanisms to their home position.
  • An example of this type of construction is shown in United States Patent No. 2,628,778, issued Feb. 17, 1953, on the application of Maximilian M. Goldberg. Once the springs have become worn through use or clogged with dirt, the transfer pawls are not returned in time for the next machine operation.
  • the mechanism of this invention is also associated with a machine having an add-subtract totalizer in which during a machine operation a transfer may occur between the highest order totalizer pinion and the lowest order totalizer pinion. It is important that prior to and during this operation the transfer pawls in the amount banks be prevented from being accidentally moved.
  • a mechanism for restoring actuated transfer members including a drive member mounted adjacent a transfer member and having a first portion which when positioned adjacent said transfer member prevents said transfer member from being actuated and a second portion which cams the transfer member, when actuated, to its home position.
  • FIG. 1 is a partial detailed side view of an amount 'bank showing the transfer mechanisms utilized in the present embodiment.
  • FIG. 2 is an exploded detailed oblique view of the transfer mechanisms including the totalizer pinions mounted in an adjacent amount bank.
  • FIG. 3 is a top detailed view of the mechanisms shown in FIG. 2.
  • FIG. 4 is a partial detailed side view of the lowest order amount bank showing the add-subtract totalizer pinion Patented Apr. 29, 1969 and the overdraft mechanism utilized in the present embodiment.
  • FIG. 5 is a partial detailed side view of the add-subtract totalizer pinions shown in engagement with their reversing gears.
  • FIG. 6 is a rear view of the add-subtract totalizer pinions shown in FIG. 5.
  • FIG. 7 is a partial detailed front view of the overdraft trip mechanism in a position to receive amounts into the negative totalizer pinion.
  • FIG. 8 is a partial detailed side view of the overdraft trip mechanism in a negative position.
  • FIG. 9 is a partial detailed front view of the overdraft trip mechanism in a position to receive amounts into the positive totalizer pinions.
  • FIG. 10 is a partial detailed view of the overdraft trip mechanism in a positive position.
  • FIG. 1 there is shown a partial de tailed view of an amount keybank of the transfer mechanism used in the present embodiment.
  • the machine to which the present invention is directed is a cash register of the type disclosed in the co-pending United States patent application of Louis E. Zurbuchen and Freeland R. Goldammer, Ser. No. 618,598, filed Feb. 27, 1967.
  • information set up on the keyboard of the machine by the depression of the required keys is entered into a number of totalizers.
  • Each totalizer has a capacity of storing nine units. When additional amounts are added to the totalizer which total more than nine, a transfer operation occurs, in which one unit is transferred to the next higher order totalizer by the use of a transfer mechanism.
  • the present machine includes three rows of totalizer pinions 19 and one row of add-subtract totalizer pinions 20.
  • Each of the pinions 19, 20 utilized in the totalizers contains a tooth 21 (FIGS. 1 and 2), which is wider than the other teeth 22 of the pinions.
  • one of the rows of totalizer pinions 19, 20 is raised in an upward direction to engage the tooth portion 23 (FIG. 4) of the primary rack 24 (FIG. 3) of one of the amount rows.
  • the primary rack has been moved to a position commensurate with the amount key that has been depressed in the amount bank.
  • the primary racks 24 of the machine are moved to the left, to their home position. This action rotates the engaged pinions 19, 20 counter-clockwise, as viewed in FIG. 1, thereby adding the amount into the totalizer pinions.
  • the wide tooth 21 passes from the ninth position to the zero position, it engages and rocks clockwise an arm 25 of a transfer trip pawl 26 rotatably mounted on a stud 27 secured to a transfer pitman 50 mounted adjacent said trip pawl.
  • the trip pawl 26 is normally urged counter-clockwise by a spring 28, which is connected between a right-angle end portion '30 of the trip pawl and an end portion 31 of a transfer latch arm 32, rotatively mounted on the stud 33, which is also supported on the transfer pitman 50*.
  • a second spring 34 mounted between the end portion and a right-angle stem portion 35 of a transfer arm 36, urges the transfer arm 36 clockwise in a manner to be described more fully hereinafter.
  • the latch arm 32 has a finger 37, which is normally positioned against a step 38 of the trip pawl 26 by the action of the spring 28.
  • the finger 37 of the latch arm Upon the clockwise rotation of the trip pawl 26 'by the wide tooth of its associated pinion, the finger 37 of the latch arm is positioned in an upper step portion 40 of the trip pawl, thereby holding the trip pawl in a trip position. This is the position of the right-hand trip pawl shown in FIG. 1.
  • FIGS. 2 and 3 there are shown an exploded view and a top view of the transfer mechanism.
  • the transfer arm 36 is rotatively mounted on a hub portion 41 of the trip pawl 26, which in turn is mounted on the stud 27.
  • a stud portion 42 of the transfer arm is positioned adjacent a stop portion 43 of the trip pawl26.
  • the transfer arm follows the movement of the trip pawl 26.
  • the clockwise rotation of the trip pawl 26 by the action of the wide tooth 22 results in the clockwise rocking of the transfer arm.
  • the primary rack may not have returned to its home position. If this is the case, upon returning to its home position, the rightangle extension 45 cams the hook 44 of the transfer arm counter-clockwise against the action of the spring 34. As soon as the extension 45 passes under the hook 44, the spring 34 rocks the hook 44 clockwise over the extension 45.
  • each amount bank also includes the transfer pitman 50 and a transfer restoring slide 51.
  • the pitman is slidably supported on a pair of rack support 'bars 52.
  • the transfer restoring slide is slidably mounted on a pair of studs 53, one of which is shown in FIG. 1.
  • the studs 53 are supported by the transfer pitman 50.
  • a transfer cam 55 Secured to a cam shaft 54, located below the transfer pitman 50, is a transfer cam 55. Associated with the cam is a transfer cam arm 56, rotatably mounted on a stud 57 secured to the transfer pitman 50, and a transfer pitman cam arm 58 rotatably mounted on a shaft 60, which is supported within the machine. As the cam 55 is rotated clockwise during a machine operation, a high portion 61 of the cam engages a cam roller 62, mounted on the pitman cam arm 58, rocking the cam arm counterclockwise. Movement of the cam arm 58 allows a stud 63, mounted on the cam arm, to move the transfer pitman 50 to the left, as viewed in FIG. 1. This movement of the pitman is against the action of a spring 64, mounted between the pitman and a stationary comb 65.
  • Movement of the pitman 50 also carries the transfer restoring slide 51 to the left until the edge 66 of the slot 67 contacts a rear portion of the comb 65. Further movement of the pitman tensions a spring 68, mounted between a stud 70, secured to the pitman 50, and a second stud 71, mounted on the restoring slide 51. Movement of the transfer pitman cam arm 58, in actuating the pitman 50, also rotates a transfer restoring arm 72, rotatably mounted on a stud 73, due to the action of a spring 74, connected between the restoring arm and the cam arm. Counterclockwise rotation of the restoring arm 72 positions its tail 75 against the transfer restoring slide 51, thereby preventing further movement of the slide to the left, as viewed in FIG. 1.
  • the machine is equipped with an add-subtract totalizer 20 (FIG. 4), which is usually referred to as a crossfooter.
  • the crossfooter consists of a plurality of sets of plus and minus totalizer pinions, there being one set for each amount row. Amounts entered into the plus or minus pinions are subtracted from the amounts contained in the other pinion. When the amount entered exceeds the amount existing on the other pinion, an overdraft occurs.
  • each set of crossfooter pinions consists of a plus totalizer pinion 77 and a minus totalizer pinion 78.
  • a set of reversing pinions 80, 81 Associated with each of these pinions is a set of reversing pinions 80, 81.
  • the reversing pinion 80 engages the plus totalizer pinion 77, while the reversing pinion 81 engages the minus totalizer pinion 78.
  • the reversing pinion 80 is secured to a shaft 82, on which is mounted a reversing gear 83, while the reversing pinion 81 is secured to a shaft 84, on which is mounted a reversing gear 85.
  • both reversing gears 83, 85 engage each other.
  • FIGS. 7 through 10 there are shown detailed views of the plus and minus totalizer pinions 77, 78, located in the highest order amount bank.
  • FIG. 7 is a front view of the crossfooter, showing the minus totalizer pinions 78 engaged by the primary racks 24, while FIG. 9 shows a plus totalizer pinion 77 engaged by the primary rack 24.
  • the line of crossfooter pinions 20 is shifted to position either the plus or the minus totalizer pinion so as to be engaged by the primary rack 24. This shifting of the crossfooter is determined by the transaction key depressed on the keyboard.
  • an overdraft trip mechanism which consists of trip pawls 86, 87 secured together and an overdraft arm 88, pinned to an overdraft shaft 90.
  • the shaft 90 extends between the gigliest order amount bank and the lowest order amount
  • the overdraft shaft 90 is normally in one of two possible positions and indicates whether the crossfooter contains a positive amount or a negative amount. If the crossfooter contains a positive amount, the overdraft shaft is in the Plus, or positive, position (FIG. 10). If the crossfooter contains a negative amount, the overdraft shaft is in the Minus, or negative, position (FIG. 9).
  • the plus totalizer pinion 77 contains the true amount
  • the minus totalizer pinion 78 contains the nines complement of this amount to 999,999.99. If a sufiiciently large amount is sub- '5 tracted from the crossfooter, an overdraft occurs. The amount in the crossfooter becomes negative, and the minus totalizer pinions contain the true negative amount after one cent has been added automatically to the totalizer pinion in the cents amount bank. This one cent is automatically generated when the overdraft shaft 90 1'0- tates from its positive position to the negative position.
  • the overdraft shaft 90 turns from negative position to positive position. Again one cent is generated and added to the amount on the plus totalizer pinion to make the necessary one-cent correction.
  • an amount is added to either of the plus or minus totalizer pinions, they are rotated counterclockwise, as viewed in FIG. 8.
  • a wide tooth 91 located on the minus pinion 78, rocks the overdraft trip pawl 87 counterclockwise and the overdraft arm 88 and the overdraft shaft 90 clockwise. This moves the overdraft arm 88 from a negative position (shown in dotted lines in FIG. to a positive position.
  • the overdraft shaft is similarly moved from a negative position to a positive position.
  • the movement of the trip pawl 87 is limited by a stud 92, which is mounted between parallel abutments 93 located on the top portion of the trip pawl.
  • the overdraft shaft 90 mounted adjacent the cents amount bank, is shown with a toggle arm '96 pinned to it.
  • a second toggle arm, 97 rotatively mounted on the shaft 90, is also mounted on a stud 98, secured to a cents transfer trip arm 100.
  • a pair of springs 101 connected between the toggle arms 96 and 97, allows the toggle arms to act as a link connected between the shaft 90 and the trip arm 100.
  • Mounted on the front of the trip arm 100 is a stud 102, which is positioned within a C-shaped slot 103, located in the cents transfer pitman 104.
  • the stud 102 will be in the lower or upper portion of the slot 103. As shown in FIG. 4, the shaft 90 is in the minus position.
  • the cents transfer trip arm 100 is rocked counter-clockwise, thereby cam ming a latch-positioning arm 105 counter-clockwise, above a stud 106, mounted on the pitman 10'4.
  • Counterclockwise movement of the arm 105 allows a stud 107, mounted on the arm and positioned in a slot 108 located in an overdraft latch 109, which in turn is rotatively mounted on a stud 110 secured to the pitman 104, to rock the overdraft latch clockwise.
  • a spring 111 mounted between a stud 112, located on the latch 109, and a stud 113, mounted on the rear portion of a transfer arm 114-, rotates the transfer arm 114 clockwise, allowing the hook portion 115 to move behind the cents transfer segment 116 on the amount primary rack 24, in the manner described previously.
  • the latch arm 118 is rocked cockwise, thereby positioning an extension 121 in a lower step 122 of the latch 109, thus retaining the latch in the tripped position.
  • a stud 127 mounted on the cam 124, engages a restoring cam arm 128, rotatably mounted on the transfer pitman 104.
  • This engagement rocks the restoring cam arm counter-clockwise, resulting in movement of a restoring slide 130, slidably mounted on the pitman 104, to the right, which engages the latch arm 118 and rocks it counterclockwise.
  • This movement of the latch arm carries its extension 121 above the upper step of the overdraft latch 109.
  • the spring rocks the latch 109 counter-clockwise, allowing the engagement of the latch with the stud 113 of the transfer arm 114, which moves the transfer arm counter-clockwise to the position shown in FIG. 4.
  • the restoring slide 130 is moved to the left by the action of a spring 131 mounted between the slide and the pitman 104. This allows the spring 120 to rotate the latch arm 118 clockwise until the extension 121 is positioned against the upper step of the overdraft latch 109, as shown in FIG. 4.
  • a second stud 135 (FIG. 1) mounted thereon engages a rear portion 136 of the transfer cam arm 56.
  • This engagement rocks the cam arm counter-clockwise and the restoring arm 72 clockwise a suflicient distance to allow a cam portion 137 of the restoring arm to engage the transfer restoring slide and drive it to the right, as viewed in FIG. 4.
  • This movement of the restoring slide allows a number of cam surfaces 139, located on the lower edge of the slide, to engage each of the trip transfer latch arms 32 and drive them counter-clockwise.
  • This movement of the latch arms 32 allows a lower edge portion 138 of the arm to engage a cam portion of its associated transfer trip pawl 26, thereby positively rocking said trip pawl counter-clockwise.
  • This action positions the finger 37 of the latch arm 32 adjacent the step 38 of the trip pawl 26.
  • the counter-clockwise rotation of the trip pawl also rotates the transfer arm 36 (FIG. 2) out of engagement with the extension 45' of the next highest order transfer segment 46.
  • the spring 74 rotates the restoring arm 72 counter-clockwise, allowing the restoring slide to move to the left under the action of the spring 68, which action moves the cam surfaces 139 of the slide from engagement with the latch arm 32.
  • the spring 28 moves the finger 37 of the latch arm 32 against the step portion 38 of the trip pawl 26.
  • the transfer mechanism is in its home position.
  • means for adding one to the next highest totalizer element when one of said totalizer elements is rotated a predetermined distance including (d) a control means mounted adjacent said totalizer element and adapted to be moved to an actuated position by said totalizer element upon movement of the totalizer element through said predetermined distance, the movement of said control means adding one to the next highest totalizer element;
  • a transfer mechanism for adding one to the next highest totalizer element when one of said totalizer elements is rotated a predetermined distance; said transfer mechanism including (d) a transfer arm adapted to add one to the next highest totalizer element when actuated,
  • blocking means mounted on said slide member adjacent said latch arm and adapted to prevent said latch arm from movement when said slide means is in said first position
  • said blocking means comprises a depending extension portion of said slide member, said extension portion being positioned so as to block rotation of said latch arm when said slide member is in said first position.
  • said trip pawl contains a cam portion positioned adjacent said latch arm
  • said cam means comprises a depending extension portion located adjacent the latch arm when the latch arm is in a tripped position, said extension portion engaging said tripped latch arm and rotating it to its home position when said slide member is moved to said second position, whereby said latch arm engages the cam portion of said trip pawl, rotating said trip pawl to the home position.
