Abstract: 394,999. Calculating-machines. ELLIS ADDING - TYPEWRITER CO., 338, Elizabeth Avenue, Newark, New Jersey, U.S.A. Jan. 7, 1932, No. 444. Convention date, Jan. 8, 1931. [Class 106 (i).] In a calculating-machine having a plurality of totalizers and a travelling paper carriage, a common totalizer-engaging link has a constant excursion in every operation and carries a series of latches, one for each totalizer, means being provided which are controlled both by the carriage and by keys for rendering one or more of the latches effective to couple the corresponding totalizer or totalizers to the common engaging link. The invention is shown applied to a machine of the Ellis type having six totalizers 1 .. 6, Fig. 4. Totalizers 3, 5 are controlled by one common engaging link and totalizers 4, 6 by another common engaging link, while totalizers 1 and 2 are controlled by separate links in the known manner. Totalizer No. 3 is engaged with the actuating racks by the anticlockwise rocking of a shaft 53 on which is a crank 52 carrying a pin 51. A plate 43 secured to the main shaft 42 pivotally carries a flying lever 45 pivoted to a link 50 having a slot in which rests the pin 51. The link 50 comprises the common engaging link for Nos. 3 and 5 totalizers. A latch 61, Figs. 1, 2, and 12A, is pivoted to the link 50 and is normally pressed away from the link by a spring 64. Stops 82, Fig. 3, on a bar 83 secured to the machine carriage rock a lever 78 connected by a link 77 to a lever 70, Fig. 1. A link 67 on the lever 70 is thereby lowered and rocks a lever 66, Fig. 2, pivoted in a member 65 secured to the link 50. The lever 66 presses the latch 61 towards the link 50 so that a projection 62 on the latch lies in the path of the pin 51. When the link 50 is moved to the right by the flying lever upon the rocking of the main shaft 42, the projection 62 engages the pin 51 and rocks the No. 3 totalizerengaging shaft 53. The No. 4 totalizer-engaging shaft 163 is operated in a similar manner by a second flying lever 155 and link 160 carrying a latch 168 having a projection 169 capable of engaging a pin 161 on the crank 162 of the No. 4 shaft 163. The latch 168 is moved into operative position when a carriage stop 82 depresses a lever 153 connected by a link 147, lever 149 and link 173 to a lever 174. To engage the No. 5 totalizer, a link 86 is pivoted to the link 50 and is provided with a latch 94 having a projection 95 which can engage a pin 87 on the crank of the No. 5 totalizer engaging shaft 91. The latch 94 is moved into operative position by a lever 99 connected by a link 100 to an arm 101 on a shaft 102. An arm 103 at the other end of the shaft 102 is connected by a flexible link 106 and a lever 108 to a link 110 carrying a pin 111 which is pressed to the left by stops 114 on the carriage. The No. 6 totalizer-engaging shaft 167 is similarly rocked by a link 164 pivoted to the link 160 and having a latch 170 with a projection 171. The latch 170 is moved into operative position by a lever 311 connected by a link 310, arm 309, shaft 308, and arm 307 to a link 305. A pin 300, Fig. 3, similar to the pin 111, is moved by the carriage stops 114 and through a link and a lever (not shown) operates the link 305 to put the latch 170 in operative position. Taking totals. The depression of the No. 3 total key 115, Fig. 4, causes a latch 120 to enter a notch in the keystem, a pin 22 on the latch depressing a totals cam 123. Pawls 126, 127 connected with the cam 123 are thereby moved into the path of the flying lever 45 to cause it to perform the sequence of movements necessary for total taking. Depression of the key 115 also rocks a lever 130 pivoted at 131 and connected by a link 132 to the lever 78. The latch 61 is thus moved to couple the link 50 to the totalizer-engaging shaft 53. Similarly, the No. 4 total key 133 has a latch connected by a link 137 to a lever 138 having a pin 140 which can act on a totals cam 141. With this cam are connected pawls 143, 144 controlling the flying lever 155. A pin 150 on the keystem 133 rocks a lever 151 pivoted at 131 and connected by a link 152 to the lever 153 controlling the No. 4 totalizer-engaging latch 168. Nos. 5 and 6 total keys 177, 178, Fig. 7, are situated on the opposite side of the machine. A pin 180 on the No. 5 keystem 177 rocks a lever 181 connected by a link 183 to a lever 184 pivoted at 185. The upper end of the lever 185 bears against a pin 186 on the link 110 controlling the No. 5 totalizer-engaging latch 94, this latch being moved into operative position when the key 177 is depressed. The No. 6 latch 170 is similarly controlled by the No. 6 total key 178. The No. 5 key 177 also acts on an arm 187 attached to a sleeve 188 surrounding a shaft 190. The other end of the sleeve 188 carries an arm 191, Fig. 9, actuating a lever 196 pivoted at 197 and having a pin 200 controlling the totals cam 123. The No. 6 total kev 178 acts on an arm 201 secured to the shaft 190 which shaft at its other end carries an arm 203 linked to a lever 205 pivoted at 206 and controlling the totals cam 141. Taking sub-totals. Releasing the totals keys. To the main shaft 42 is secured a plate 234, Fig. 9, which carries the flying levers 237, 238 controlling totalizers Nos. 1 and 2. The plate 234 has a stud 233 which moves into the region of a lever 230 pivoted to a slidable release bar 224. During the clockwise movement of the plate 234 the stud 233 wipes past the lever 230 but on the return movement of the plate the top of the lever 230 contacts with a fixed stud 232 and so causes the release bar 224 to move to the left. Projections 239 on the release bar contact with the latches of the Nos. 3 and 4 total keys. The release bar 224 is connected by an arm 222, shaft 221, and arm 220, Fig. 7, to a second release bar 217 having projections for releasing the latches of the Nos. 5 and 6 total keys. To take a subtotal, a key 243 is depressed at the same time as the corresponding total key. A subtotal release bar 225 is situated adjacent the release bar 224 and is connected at 226 to a lever 227. The bar 224 carries a pin 240 and the bar 225 a pin 241 and when the subtotal key 243 is depressed a blocking piece 242 is inserted between the two pins. During the clockwise movement of the plate 234 a pin 235 thereon rocks the lever 227 and moves both bars 224, 225 to the left to release the total and subtotal keys, whereupon the total pawls 143, 144 or 126, 127 are moved away from their respective flying levers at such a time in the operative cycle that a subtotal is taken from the corresponding totalizer. In a modification, the Nos. 5 and 6 total keys are arranged on the same side of the machine as the Nos. 3 and 4 total keys. Specifications 28253/08, [Class 106, Registering &c.], and 348,105 are referred to.
