Original application filed March 11, 1921, Serial No. 451,508. Divided and this application 1923. Serial No. 650,390.

This invention relates to cash registers, and more particularly to indicating mechanism therefor.

The subject matter of this application constitutes a division of a copending application, Serial No. 451.508, 'filed on March ll, 1921, by B. M. Shipley.

The principal object of this invention is to provide a machine of a well. knowntype with mechanism tor disabling its indicating mechanism to prevent a display of totals or sub-totals.

The specific object of this invention is to render such disabling mechanism etiective as an incident to the seting ot a control lever preparatory to total and subtotal printing operations.

Mechanism is therefore provided herein for disabling the indicating mechanism on total The machine to which the invention is shown appliedis of the general type shown and described in Letters Patent oi the United States No. 1 ,230,864 issued to W. A. Ghryst on June 526, 191?; Letters Patentof the United States. Nos. 1242.170 and 1,39%,256, issued to F. L. Fuller on Oct. 9, 191'? and Oct, 18, 1921, respectively. it is to be understood however that this invention, is applicable to many other types of machines, and it is therefore not desired to limit its use to the machineshown herein.

In View of the fact that a very complete description of the machine is given in the before-mentioned patents, only a very brief description thereof will be included herein. The keyboard comprises a plurality of banks of depressible keys for setting up the amounts to be entered and for controlling the selection and engagement of the totalizers 26. An amount bank and differential mechanism are shown in Fig; 1. These keys when depressed are adapted to cooperate with a bell. crank 27 carriedby totalizer actuating Alatch member supported on said bellcrank normally connects the actuating n'iember 28 to a driving segment 29. This segment is given an invariable extent of movement on every operation of the machine by means of pair of cams carried by the main drive shaft 46, a it-shaped member 47 and a link 48., ll of which are well known in the art. When the segment 29 isgiven this invariable movement the or" the depressed key. vThis moves the latch member 24 to disconnect the actuating member 28 from the segment 29 and to hold the actuating member in its ad usted positlon as is well known in the art.

When the segment 29 is returned to the position shown in Fig.1, surface 30 therei on, engages a pin 31 carried by the actuating member 28 and returns this member to zero. Before this is accom )lished the selected to talizers 26 are rocked into engagement with the actuating member that when this member is returned to zero the value represented by the depressed key will be entered thereon.

Pivoted to the actuating member 28 a beam 32 which is bifurcated to cooperate with a stud carried by a link 34. By means of this beam 32 the differential movement of the actuating member 28 is transferred to the link 34 in a manner fully described in the above referred to patents.

At its lower end the link 34 is pivoted to an arm loose on a rod 36 and fast on a spiral. segment 3'? also carried by said rod. The segment meshes with a spiral pinion 38 fast on a shaft 39 supported by laterally spaced frames. Also fast on the shaft 39 is a segment 4:0 which meshes with a rack 41 (Fig. 7). This rack also meshes with a pinion 42 fast on the inner end of a sleeve 43 which at its outer end *arries a similar pinion l4 meshing with a type wheel 45. It can be seen from the above that the movement of the differential actuating member 28 will, through the train of mechanism just de scribed, move its appropriate type wheel a corresponding extent.

There are two groups of indicators (Fig. 1) for each of the amount banks of keys 25. One group of indicators indicates toward the front-of the machine and the other group indicates toward the back of the machine. There are other groups of indicators which are associated with the various control banks of keys but as all of these indicators are mounted in a similar manner the group associated with one amount bank only is illustrated and described herein. The group of indicators 55 (Fig. 2) which indicate toward the front of the machine are carried in av casing 56 and rest upon a ledge 57 of a plate 58 slidably mounted on rollers 59 on rods 60 supported by two plates 61. only one of which is shown. The plates 61 are secured to the side frames of the machine by studs 62. The plate 58 has teeth 63 meshing with a segment 64 integral with a segment 65 fast on one of a plurality of sleeves 66 supported by a shaft 67. The upper end of the link 34 is. pivoted to the segment 65 so that the differential movement of the differential actuating member 28 is transmitted by means of beam 32 and link 34 to the segment 65 and thereby to the segment 64 and plate 58. In this manner the plate 58 carryingthe group of indicators for indicating toward the front of the machine is differentially positioned to bring any desired indicator into operative relation with an in dicator-lifting means to be hereinafter de scribed.

The indicators 55 which indicate toward the back of the machine are differentially positioned by means of a plate similar to plate 58. As the indication from the back of the machine is the reverse of that lookiug from the front, each of the segments 65 is secured to a sleeve (36 so that the move ment im 'iarted to the segment 65 is tl'irough the sleeve 66 imparted to the plate 58 which carries the indicators for indicatin toard. the back of the machine. The front and back indicators for the middle amount bank are carried in casings 56 supported by plates 58 integrally connected as shown in Fig. l

[iii/Hay; moo/1 (moon.

After the indicators have been ('llllfi1611- tially positioned according to the keys which have been depressed, the selected indicator is exposed to view. This mechanism is substantially the same as that shown and des -ribed in the patent to Fuller No. 1,168,?48 granted Doc. a, l9l5. licfore the indicators 55 can be di'i ercntialiy positioned it is necessary to lower those exposed during the prc vious operation. A frame 70 (Fly. 2), rectangular in shape, has at each end an arm Tl carrying a. roller '72 projecting into a slot 7-3 in each plate 61. The frameTO also has projections 71: at the front and back thereof adapted to engage the indicators in a manner fully described and illustrated in said patent. P votcd on a stud 75 on the frame '70 is a link T6 also pivoted to a lever 7? fast on a shaft 78 mounted in the side frames of the machine. There is a link 76 and a lever 7T 2 each end of the machine in order that the :i' ame TO may be lifted evenly to prevent bin Pivoted on a stud 79 on the lever roller 81. projecting into the short portion of an L-shaped slot 82 in a lever 83 loose on a rod 84; carried by the side frames of the machine. The lever 83 has two rollers 85 and 86 cooywwting with. cams 87 and 88 respectivcly, fas" on the shaft The link 80 has a roller 89 a; nst. which rests an edge 90 of a pawl 91 loose on a rod carried by the side frames. A spring 93 holds the pawl 91 against the roller ti!) so that the roller 81 is normally maintained in the short portion of the L-sha ed slot 82.

From the above de-crii tion it ca be clearly seen that when the cams and 88 are rotated count er-clockwise the lever 83 is rocked clockwise thereby moving the link 80 downward in the d: cclion of its length and rocking the levers Ti and shaft '78. This movement of the levers 7''? through "the links 76 lowers the fra in TO and the indicators which were cxpce L. du -in ay tho operation. As the link 80 is bcin huncreth the spring 93 maintains the tension against the roller 89 so that the roller til cannot become disei'ie'agcd from the short portion of the slot 82. A stud 9 3i limits the clockwise movement of the pawl 01. After the arm usly cxoosed indicators 55 have been lowere h as j st descril'ied, and

after the plates 58 have been differentially positioned to select a new indicator, the cams 87 and 88 rock the lever 83 counter-clockwise to home position. This raises the link and consequently rocks the levers 77 counterclockwise to home position, thereby raising the links 76 to raise the frame 70, whereby the projections 74: thereof engage the selected indicators 55 and expose them to View;

After the frameis in its lowerposition it is held locked in this position until the plates 58 have been differentially positioned to select a new indicator. This locking means will now be described. Slidably mounted on the rods 60 is a plate (Fig. 2), having a slot 96 engaged by a pin 97 on a lever 98 on a shaft 99 supported by the side frames. Pivoted tothe lever 98 is a link 100 (Fig. 4) which is pivoted to a lever 101 (Fig. looseon the stud 84:. The lever 101 has rollers 102 and 103 cooperating with cams 104 and 105 respectively fast on the shaft 16. The cams 10% and 105 are so timed that after the frame it) has been lowered said cams rock the lever 101 clockwise, which, through the link 100, rocks the lever 98 counter-clockwiseand moves the plate 95 toward the left, whereupon a. projection 106 thereof engages the roller 72 on the arm 71, thereby holding the frame 70 in its lowered position until the indicators 55 have been selected, after which the counter-clockwise movement of the lever 101 to normal position rocks the lever 98 clockwise to disengage the projection 106 from the stud 72 thereby allowing the frame 70 to be raised to expose the selected indicators to view.

Alibi 22g mechanism.

Each of the segments 65 has aiming notches therein with which an a-lining bar 107 cooperates. This alining bar 107 is in tegral with. parallel arms 108 2 and at) fast on the shaft 99. as above described. The lever 98 is fast on the shai 90. Therefore when said lever is rocked 'cotmter-clockwise the shaft 99 rocks the arms108 counter-clockwise and disengages the alining bar 107 from the notch in the segment 65 so that this segment may be differentially positioned under the control of the direrential r echanism. 'lVhen the lever-98 is rocked clockwise to normal position the aliner 107 is again engaged with a notch on the segment 65 to hold the segment in proper position until a subsequent operation of the machine.

Thereis also another alining mechanism 109 which directly alines the plates 58. This aliner 109 is in the form of an angle iron (Figs. 2, 3 and 4). in alinement with each plate 58 the aliner 109 has slot 110 and also an alinin tooth 111 which cooperates with notches 112 in. the plate 58. The

aliner 109 is secured at each end to horizontal portions of levers 113 pivoted on studs 11% mounted in the plates 61.

Pivoted to the levers 113 are links 115 which are also pivoted to the levers 98. When said levers are rocked counter-clockwise, as previously described, the links 11: rock the levers 113 clockwise and disengage t'le alining teeth 111 from the notches 112 of the plates 58. The slots 110 of the aliner 109 then act as a guidefor the p 58 to hold them in proper late :11 position. Amer the desired indicaters have been selectedand before the frame 70 is raised to expose the selected indicators to View, the levers 98 are rocked clockwise to home position, which movement through the links 115 rocks the levers 113 counter-clockwise, whereby the teeth 1 11 again engage the notches 112 and hold the indicators in proper alinem-ent until the ma chine is again operated.

Indicator crippling on. totalizing operations.

of this link are bifurcated to surround the rod 92 and the shaft 11'2". The link 129 carries a roller 130 adapted to cooperate with a. surface 131 of the previously described link 80.

It is well known in the art that machines of this type are controlled on total and subtotal priiitinr;- operations by means of a total lever 135 6). Movement of the total lever either up or down, out of its addingposition, rocks the sl aft 11'? clockwise, to lock out the amount keys and certain banks of control keys, and to control the machine for a two cycle operation as vell known in the art. This movement is accomplished in the following manner: integral with the total lever 25 is 5 plate 136. A pivoted lever 138 cc ries a roller cooperating with a slot 13? formed in this plate. Also pivoted on the same center the lever 138 is a member 1.39 which has a'slot formed therein into which projects a roller carried by an arm 1 .210 on shaft 117. The lever 138 and member 139 connect-ed together by a spring 1 11 and a pin and slot connection. it can be seen from the above that when the total lever moved out of its adding position, the lever will be rocked counterclockwise due to the shape of the slot 137. This movement of the lever 138, through the spring 1 11, ,ocks the me. her 139 also counter-clockwise. which will. in turn, rock the arm 14:0 and shaft 11'? clockwise.

Upon this movement of the shaft 117 the rm 118 will be rocked counter-cloclnvise as seen in 2. This n'iovement of the arm 118, through the engagement of the pin 119 with the slot 120, moves the link 129 to the left. This positions the roller 130 into cooperative relation with the surface 131 of the link 80.

During adding operations it will be remembered that the link 80 is moved downward by the lever 83 at the beginning of the operation to lower the indicators which were exposed (hiring the last previous operation. During the first part of the movement of the shaft 16 (Fig. 2) the lever 83 is rocked clockwise and lowers the link S0, which lowers the previously exposed indicators to their normal positions. As the link 80 nears the end of its downward movement. during a total or sub-total printing operation the surface 131 engages the roller 130 which has been moved to the left by movement of the total lever, and rocks the link 80 clockwise about the stud 79 thereby disengaging the roller 81 from the short portion of the L-shaped slot and positioning it in the end of the long portion of said slot. Then, when the lever 83 is moved connter-clockwise, to home. position, it has no etl'ectupon the link 80, and. consequently the indicator lifting frame is not raised to expose selected indicators to view. During the second rotation of the shaft 16 the lever 83 is again rocked clockwise, thereby positioning the short portion of the slot 82 opposite the roller The lever 83 is then again rocked counter-clockwise to home position without lifting the link 80. The total or sub-total printing operation is now completed with the roller 81 near the bottom of the long portion of the slot 82. During a total or sub-total printing operation, whichever the case may be, the shaft 117 is rocked still farther in a counter-clockwise direction, by mechanism not shown herein but disclosed in the patents referred to. As the lower portion of the slot 120 is concentric with the shaft 117 the link 129 receives no farther movement to the left than that which was given it by the first conntcr-clockwise movement of the shaft 117 under the direct control of the total lever 135.

When the total lever is again moved to its adding position it rocks the shaft 117 to home position, thereby rocking the arm 11S clockwise, which moves the link 129 to the right to the position shown. As the machine is now operated and the short portion of the slot 82 positioned opposite the roller 81, the s nking 93 through the engagement of the surface 90 of the pawl 91 with the roller 89 will rock the link 80 connter-clockwise thereby mo ing the roller 81 into the short portion of the slot 82. \Vith the roller in this position, the counter-clockwise fi'lOVGHlGnt of the lever 83 to home position raises the link 80, rocks the arm 77 counter-clockwise and raises the link 7 6 to expose the selected indicators, for this operation, to View.
