377,430. Calculating- machines. JAMES, R. W., 11, Queen Victoria Street, London.-(Remington Typewriter Co. ; Ilion, New York, U.S.A.) July 24, 1931, No. 21244. [Class 106 (i).] In a combined typewriting and calculating machine having a detachable totalizer adjustably mounted on a carriage and adapted to be moved step by step into a computing zone, aligning means carried on the totalizer are adapted to engage successively a plurality of adjacent wheels and to be normally in engagement therewith, means operable only when the totalizer is in the computing zone being provided for shifting the aligning device out of engagement with the wheels. The totalizer is held in place on a bar 1 by a spring-controlled lever 10 having a tooth 15 engaging a rack 16 on the machine carriage. The totalizer is disengaged by pressing a fingerpiece 14 on the lever 10. Actuating mechanism. The depression of a key rocks a cam 72 through a link 68 and swings, about an axis 75, a universal rod 73 forming part of a frame 74. An arm 76 of the frame is connected by a link 77 to a cam 78 which causes the clockwise swinging of a dog 40 controlling the transfer and aligning mechanisms. Another arm 85 of the frame 74 rocks a cam 82 pivoted at 83 and effects the withdrawal of a pawl 81 from the teeth of the master wheel 67. Further movement of the cam 72 causes, through a pin-and-slot connection 69a, the rocking of a cam 71 the face 88 of which engages a pin 89 on a lever 90 secured to a shaft 91 carrying a sector 92 connected by gearing 93 to the master wheel 67. Transfer mechanism. The master wheel 67 is connected to the totalizer wheels 27 through pinions 29, 28. Each pinion 29 has secured to it transfer teeth 34 and a gapped locking disc 32 engaging a star wheel 31 and a Geneva pinion 30 which are secured together and are also integral with a pinion engaging the next higher pinion 29. There are two sets of pinions and wheels 31, 30, each set operating in alternate denominations, to reduce the space between the numeral wheels. Each denominational group of wheels 31, 30 is carried by an arm 35 or 36 pivoted at 8 or 7 respectively. Before actuation, the dog 40 swings the arm carrying the wheels of the denomination next below that engaged by the master wheel to unlock the counting train at that point. A projection 44 on the arm so moved rocks a bar 41 to lock all the remaining arms. Aligning mechanism. Pivoted to the bar 41 is a link 60 connected to a lever 57 pivoted to a lever 63, Fig. 3. This lever rocks abouts its end 65 and engages with and aligns the pinions 28. The rocking of the bar 41 moves the lever 63 into the inactive (dotted) position during the actuation of the counter. The lever 63 does not act on the two right-hand pinions 28. The bar 41 is controlled by a spring 48, Fig. 8, acting through a lever 52 having an aligning tooth 56 engaging one of the wheels 29. The wheels 29 are also aligned by a tooth 94 fixed to the machine frame at the right-hand side of the master wheel.
